Scientists Think They Know How Stress Causes Gray Hair – Healthline

Posted: January 28, 2020 at 2:48 pm

Sorry Mom and Dad: It turns out you might not have been exaggerating when you told us your children made your hair turn gray.

Stress may play a key role in just how quickly hair goes from colored to ashen, a study published this past week in the journal Nature suggests.

Scientists have long understood some link is possible between stress and gray hair, but this new research from Harvard University in Massachusetts more deeply probes the exact mechanisms at play.

The researchers initial tests looked closely at cortisol, the stress hormone that surges in the body when a person experiences a fight or flight response.

Its an important bodily function, but the long-term presence of heightened cortisol is linked to a host of negative health outcomes.

But the culprit ended up being a different part of the bodys fight or flight response the sympathetic nervous system.

These nerves are all over the body, including making inroads to each hair follicle, the researchers reported.

Chemicals released during the stress response specifically norepinephrine causes pigment producing stem cells to activate prematurely, depleting the hairs reserves of color.

The detrimental impact of stress that we discovered was beyond what I imagined, Ya-Chieh Hsu, PhD, a lead study author and an associate professor of stem cell and regenerative biology at Harvard, said in a press release. After just a few days, all of the pigment-regenerating stem cells were lost. Once theyre gone, you cant regenerate pigments anymore. The damage is permanent.

But stress isnt the only or even the primary reason that most people get gray hair.

In most cases, its simple genetics.

Gray hair is caused by loss of melanocytes (pigment cells) in the hair follicle. This happens as we age and, unfortunately, there is no treatment that can restore these cells and the pigment they produce, melanin, Dr. Lindsey A. Bordone, a dermatologist at ColumbiaDoctors and an assistant professor of dermatology at Columbia University Medical Center in New York, told Healthline. Genetic factors determine when you go gray. There is nothing that can be done medically to prevent this from happening when it is genetically predetermined to happen.

That doesnt mean environmental factors such as stress dont play a role.

Smoking, for instance, is a known risk factor for premature graying, according to a 2013 study. So kick the habit if you want to keep that color a little longer.

Other contributing factors to premature graying include deficiencies in protein, vitamin B-12, copper, and iron as well as aging due in part to an accumulation of oxidative stress.

That stress is prompted by an imbalance between free radicals and antioxidants in your body that can damage tissue, proteins, and DNA, Kasey Nichols, NMD, an Arizona physician and a health expert at Rave Reviews, told Healthline.

And some degree of oxidative stress is a natural part of life.

We would expect increasing gray hair as we advance in age, and we see about a 10 percent increase in the chance of developing gray hair for every decade after age 30, Nichols said.

Changes you can pursue to delay premature grays include eating a diet high in omega-3 fatty acids such as walnuts and fatty fish, not spending too much time in the skin-damaging and hair-damaging ultraviolet light of the sun, and taking vitamin B-12 and vitamin B-6 supplements.

That said, if you are going gray prematurely, it wouldnt hurt to go have a checkup just in case natural genetic factors arent the sole culprit.

The new Harvard research is only a mouse study, so replicating the same results in a human study would be necessary to strengthen the findings.

But the Harvard research has implications far beyond graying hair, with the hair color change merely one obvious sign of other internal changes as a result of prolonged stress.

By understanding precisely how stress affects stem cells that regenerate pigment, weve laid the groundwork for understanding how stress affects other tissues and organs in the body, said Hsu. Understanding how our tissues change under stress is the first critical step towards eventual treatment that can halt or revert the detrimental impact of stress.

Might that also mean someday halting and reverting the march of premature gray hair? Its too soon to tell.

We still have a lot to learn in this area, Hsu said.

In a race against terminal illness, former Obama staffer with ALS and his wife find new hope a year later – PostBulletin.com

Posted: January 28, 2020 at 2:48 pm

CHICAGO - Brian Wallach wasn't supposed to live to see his younger daughter's first birthday.

Diagnosed with amyotrophic lateral sclerosis (ALS), a terminal disease with no cure, doctors told him in 2017 that he might have six months to live.

Today, he's focused on being there for his daughter's future firsts: kindergarten drop-off, middle school dance, wedding day.

More than two years after his diagnosis, he has been lucky, he said, to experience relatively limited progression of his disease. After some balance issues, the Kenilworth resident now uses a cane - or, as he is careful to specify, a "cool walking stick" - to get around.

When Wallach was diagnosed, neither he nor his wife, Sandra Abrevaya, knew much about ALS, a neurodegenerative disease that affects nerve cells in the brain and the spinal cord, eventually paralyzing even the body's ability to breathe.

In response to Wallach's diagnosis, the couple, both 39, launched I AM ALS in 2019. Former staffers in the Obama White House, they marshaled lessons learned while campaigning - gathering information, forming consensus, considering the impossible possible - to build a force to mobilize hope and change for those facing a disease they say can and should be cured.

Rays of hope are beginning to emerge through an innovative trial that received FDA approval last week to test several drugs at the same time, a bipartisan congressional caucus, doubled federal funding, and support from groups like the Chan Zuckerberg Initiative, which gave the couple's organization a $453,000 grant in September.

"Last year we made hope a word that was OK to use," Wallach said. "This year we have to make hope real."

Audaciousness is the only option, the couple says, in their race against the clock.

Wallach logged 120,000 miles in the air last year, including traveling to Washington, D.C., in April, where he testified before Congress and asked legislators to amp up funding.

"Last year, every time someone said, 'Do you want to speak to us,' I said, 'yes.' Every time someone said, 'There's a meeting,' I said, 'I'm going.'" he said. "Every time there was anything, I said, 'Great, I'm on the plane.'"

Until October, when Wallach fell while exiting a Lyft in Boston after swinging a heavy backpack onto his back. Thirteen staples in his head later, and after terrifying Abrevaya with a phone call, the two agreed he wouldn't travel alone anymore. He's maintaining momentum for the cause with more hours in his home office and fewer in airports.

In December, I AM ALS debuted billboards around Times Square as part of its #CuresForAll campaign aimed at informing the public about the impact a cure or better treatment for a neurodegenerative disease can have on other diseases such as multiple sclerosis, Alzheimer's and Parkinson's. ALS patients and their families from states including Michigan, Maine and Colorado were in New York for the launch.

The billboards noted the number of people lost to ALS each day - 16 - with photographs of those who died in 2019. Days earlier, Pete Frates, a founder of the viral fundraiser the Ice Bucket Challenge, which raised $115 million, had died. He was 34.

The campaign was also shared on social media. The posts expressed the suffering and loss nationwide: a mother wrote about her son who was diagnosed at 20 and died at 28; a son posted in honor of his dad; Colorado Rep. Jason Crow posted a message honoring his cousin.

It's time, the couple said, to switch ALS conversations from a diagnosis rooted in darkness to the faces of people bravely moving forward. They want to speed development of potential cures and give patients more access to experimental treatments.

That's not an unreasonable goal, said Sabrina Paganoni, a faculty member at The Sean M. Healey & AMG Center for ALS at Mass General in Boston, which plans to test at least five different medications for ALS at the same time, a first for the disease and something she said could be a huge turning point.

On Wednesday, the Healey Center announced it received FDA approval to move forward with testing the first three drugs: Zilucoplan, Verdiperstat and CNM-Au8. Similar to how cancer drugs are already tested, this gives patients access to more treatments and allows researchers to quickly collect data and accelerate the pace toward a cure.

"This is a very exciting time in the history of ALS," Paganoni said. "I think this is going to be the decade when ALS is changed from a rapidly fatal disease to a more chronic disease that we can manage."

For years, Steve Perrin, the chief executive officer at the ALS Therapy Development Institute, has monitored clinical trials for ALS. So far, he said, the two drugs approved by the FDA, Radicava and Rilutek, are "a very marginal slowing down of disease."

This year, he said the quality of drugs going into trials seems improved. He is excited about several trials, including one studying stem cells and another testing a drug to potentially slow progression in some patients.

"As a patient you want to see something measurable, and I don't mean measurable in days," he said. "If I'm a patient, I want to see something, and I want hope for myself and my family. I want something that is going to slow the disease down so I can watch my kids growing up, I can watch them graduate from college, I can watch them marry."

But that takes resources.

"We are in a time when we can reasonably say that there's going to be new treatments available," Paganoni said. "But we need more funding and support, so all of this can happen, and happen soon."

Nearly every moment feels like a push-pull for Wallach and Abrevaya.

Do they spend more precious minutes with their two daughters, ages 4 and 2, or do they spend time away, among strangers - on a plane, in a researcher's office, walking the halls of Congress - with the hope that those minutes will, someday, result in time banked to create more family memories.

"The hardest balance, if I'm honest, is, I love every minute I have with them," Wallach said about his daughters, "but I also feel this pressing sense of, I need to be working towards a goal of actually finding a cure."

"We're doing that so we have a shot at a real future together," Abrevaya said about their time spent traveling and advocating.

At home, when the family heads for the door, the toddlers reach for their father's shoes, and they get his walking stick.

"While that both fills your heart with joy and appreciation, it's also painful that your toddlers are being put in this position," Abrevaya said.

The parents guard normalcy. They take their daughters to swim at the neighborhood pool and on vacation with friends. Wallach wishes he could lift them above his head to touch the ceiling, like their uncle can. But he can lie on the floor and play with them; he can listen to them belt out songs on their purple karaoke machine.

They find ways to lighten a heavy subject. On New Year's Eve, the two danced in a video on the foundation's Instagram, singing into hairbrushes, and Wallach promised to get an "ALS: You Gone" tattoo if 20,000 people donated $10 to a Healey Center research fundraiser. It raised $40,000 in 24 hours, Wallach said. No matter the outcome, he plans to get the tattoo.

The couple, who both work full-time jobs - Abrevaya is the president of nonprofit Thrive, Wallach works at law firm Skadden, Arps, Slate, Meagher & Flom - want more research, to create a patient navigation system, and to gather signatures for a letter asking new FDA commissioner Stephen Hahn to speed ALS patients' access to possible treatments.

And they keep looking for light. But it takes work.

Changing life with ALS for Wallach, and for other patients and their families, requires bold action from people with the power to make change: politicians, researchers, philanthropists.

As they meet others with ALS, they welcome new friends and face the pain of losing some.

"It does make you uniquely urgent in what you do," Wallach said. "You push because you have to. You push because you know that the time that we have is precious, and that you want to see 20 years from now. And know that you can make that happen."

Wallach often shares moments about his ALS journey on Twitter with his 40,000 followers. Recently, he shared something he wasn't sure he should. It was a time he was unable to find light.

On a recent night, he woke up to pain he's had for the past few months, radiating from his right hip to his right calf.

He clutched a stuffed llama his daughter gave him. And he began to cry.

"I cried because of the pain. I cried because I couldn't be the father to my girls I dreamed of being," he wrote. "I cried because I couldn't be the husband to my wife I dream of being. Because I saw the future zooming ahead, and for a brief moment I wondered if I would be a part of it."

His wife heard him crying that night. She asked what was wrong. And he said maybe they would be better off if he left, living instead in an assisted living facility. Their daughters, he told her, could have a dad who could do everything he dreamed of doing.

She looked at him in the dark. "You are my light," she said. "You are their light. The only way you are leaving us is if you die in my arms, and we aren't going to let that happen for a long, long, long time."

Tune in Tonight: Oscar-nominated The Cave debuts on National Geographic – Daytona Beach News-Journal

Posted: January 28, 2020 at 2:48 pm

Film buffs who want to see as many Oscar-nominated films as possible before the big awards should not miss "The Cave" (9 p.m. Saturday, National Geographic). For the record, this is not about the Thai cave rescue efforts to save a trapped soccer team. Nominated for best documentary, this 2019 Syrian film is directed by Feras Fayyad and is a companion to his earlier film "Last Men in Aleppo." "Cave" profiles female doctor Amani Ballour, who operated a makeshift hospital in a cave during the worst of the Syrian civil war. "Cave" has already been cited for the People's Choice Award for Documentaries at the 2019 Toronto International Film Festival.

David Attenborough narrates "Seven Worlds, One Planet" (9 p.m. Saturday, BBC America, AMC, IFC, Sundance, TV-PG), an exploration of each continent's unique species, as it turns its focus to North America.

It's always the husband! Lifetime puts a true-crime spin on its women-in-peril franchise with "Chris Watts: Confessions of a Killer" (8 p.m. Saturday, TV-14). After his wife, Shanann (Ashley Williams), and their two young daughters had been missing for some days, Chris Watts (Sean Kleier) made an emotional plea in front of television cameras. Scant days later, his charade began to unravel after he failed a polygraph and later spilled details about the murder of his family. Confessing to the murder was only the beginning of revelations that would shatter the lives of friends, neighbors and colleagues as they learned secrets of his dark double life.

A special report, "Beyond the Headlines: The Watts Family Tragedy" (10 p.m.) follows.

Monday marks the 75th anniversary of the liberation of the Auschwitz death camp. To commemorate the event, the History Channel returns to history, for one night at least, with "Auschwitz Untold" (9 p.m. Sunday, TV-14), a history of the Nazis' Final Solution program, including interviews with survivors who recall their internment when they were only children.

Discovery offers a special airing of the 2018 historical drama "Who Will Write Our History" (3 p.m. Sunday, TV-14). Joan Allen and Adrien Brody headline an impressive voice cast in this handsome production about a group of scholars, journalists and activists in Poland's Warsaw Ghetto, who decided, at great personal risk, to write and research the real story of their occupation and oppression in order to counter Nazi propaganda that depicted Jews as filthy vermin fit for extermination.

Linking the Maitland family's "vacation" in Ohio to similar mysterious killings, Holly begins to see patterns that defy rational explanation on "The Outsider" (9 p.m. Sunday, HBO, TV-MA). Portrayed by actress Cynthia Erivo ("Bad Times at the El Royale," "Harriet"), investigator Holly Gibney is the latest in a long line of "damaged" detectives, dating back through "Monk" all the way to Sherlock Holmes.

Her social unease and peculiar focus, born of her place on the autism spectrum, makes her one of the more compelling television characters to emerge in the new year. "The Outsider" is a very good series. Holly has all but stolen the show.

Scientists Have Created Living Robot Frogs, And They Just May Save Your Life – Parentology

Posted: January 28, 2020 at 2:47 pm

The day of the robot frog is here. Sort of. Researchers in the United States have taken stem cells from the tissue of African clawed frogs and put them together to build tiny living robots. These are the worlds first living machines, robots made from biological tissue that have advantages your run-of-the-mill plastic and metal robots dont have.

These lifeforms have never before existed on earth, Michael Levin, director of the Allen Discovery Center at Tufts University, which conducted the research alongside scientists from the University of Vermont, said. They are living, programmable organisms.

Researchers are calling these new creatures xenobots, derivedfrom Xenopus laevis, the scientific name for the African clawed frog. The botsare less than a millimeter wide, which is small enough to travel through thehuman body. And they dont look anything like the robots weve all seen before.Xenobots are basically tiny dollops of moving pink flesh.

According to CNN,the researchers took stem cells from frog embryos, left them to incubate, thenused a supercomputer to cut and shape the cells into body forms. For example,you can have a xenobot with a hole in the middle that could possibly be used todeliver medication inside the human body.

Once they were created, the robots operated on their own. Theskin cells bonded to form structure, and the heart cells would actually pulse,allowing the bots to propel themselves.

What else might the xenobots be used for? Scientists say theycould potentially be used to remove plaque from artery walls, locate anddestroy radioactive waste, and even clean up microplastic pollution in theoceans.

And although metal and plastic robots are strong and durable, there are good reasons to create bots from biological tissue. For one thing, the xenobots are self-healing. And once their task is complete, says The Guardian, they fall apart, just as natural organisms decay when they die. That makes them more environmentally friendly than traditional robots, as well.

Creating these xenobots does raise some ethical issues,particularly because future versions of them might actually have nervoussystems and cognitive abilities. And then what will they be, living creaturesor just machines?

Whats important to me, Sam Kriegman, a PhD student on the University of Vermont team, said, is that this is public, so we can have a discussion as a society and policymakers can decide what is the best course of action.

Stem Cell Therapy for Joints & Spine in Austin Texas

Posted: January 28, 2020 at 2:45 pm

Schedule a Free Stem Cell Consultation to Find Out if This Advanced Treatment Can Help You

If chronic joint pain is limiting your daily routine or preventing you from activities you enjoy; regenerative medicinemay be the answer youve been looking for!

The pharmaceutical approach to these conditions is still not effective for some 20% to 40% of those suffering from arthritis or other degenerative joint conditions. According to the National Institute of Health, Stem Cell Therapy provides a promising alternative to surgery by promoting safe and natural healing. The less invasive approach Stem Cell Therapy offers attracts thousands each year.Texas Spine and Sports Therapy Center is one of the few clinics in the country to offer Stem Cell Therapy. With convenient locations nearAustin, we are ready to get you back to the activity levels you desire.

Stem cells are found in all of us and play a key role in the bodys healing process. They lie latent in your body until they receive signals that the body has suffered an injury and then they follow your platelets to the injured site. Stem cells are able to transform into the same type of cell that was injured to promote healing. They are tasked to heal injured ligaments, tendons, tissues and bones. After an injury, or as a natural result of aging, the amount of stem cells needed in certain areas of the body declines. Stem Cell Therapy solves this problem by delivering a high concentration of stem cells into the injured area promoting natural healing.

The Stem Cell Therapy procedure is simple and takes just 15 minutes with pain relief in 24-48 hours. The therapy can be performed right in the Texas Spine and Sports Therapy Centeroffice and provides pain relief without the risks of surgery, general anesthesia, hospital stays or prolonged recovery. There is zero recovery time after Stem Cell Therapy. Most experience complete joint restoration of ligaments, tendons and cartilage in 28 days. Stem Cell Therapy is very safe and effective. The injections have been used over 10,000 times in the United States with no reported adverse side effects and have a 100% safety record in Europe with 100,000s of patients.

Stem cell treatment takes advantage of the bodys ability to repair itself. With Stem Cell Therapy, your Texas Spine and Sports Therapy CenterProvider will inject stem cells into your body. Similar to cortisone and steroid shots, stem-cell injections have anti-inflammatory properties, but offer far more benefits than those of standard injection therapies. While cortisone and other drugs only provide temporary pain relief, stem cells actually restore degenerated tissue while providing pain relief. The growth factors in Stem Cells may replace damaged cells in your body. Additionally, stem cell injections contain hyaluronic acid, which lubricates joints and tendons, easing the pain and helping restore mobility.

The Stem Cells can turn into any type of tissue found in joints other than nerve tissue. Depending on the different tissues that are damaged, the stem cells can turn into whatever your joint needs which can quite often be a combination of cartilage, ligament, tendon, bone or muscle. This is a curative treatment. You can literally grow new joints tissue. Once your joint is healed, it is healed. The oldest research to date shows that 100% of recipients who benefited from stem cell therapy were still pain free 4 years later. Stem Cell Therapy allows our state-of-the-art clinics across the Texas Hill Countryto treat and rehabilitate your pain and injuries without drugs or surgery.

El Paso scientists to deliver 3D bioprinted miniature hearts to the ISS – 3D Printing Industry

Posted: January 28, 2020 at 2:45 pm

Biomedical researchers from Texas Tech University Health Sciences Center El Paso (TTUHSC El Paso) and The University of Texas at El Paso (UTEP) are collaborating to develop artificial mini-hearts using 3D bioprinting technology for space.

These heart-tissue structures will be sent to the International Space Station (ISS) to gain insight into how microgravity affects the function of the human heart, particularly in regards to the health condition known as cardiac atrophy.

The artificial mini-heart, otherwise known as a cardiac organoid, will be produced using a combination of human stem cells and 3D bioprinting. The project, which began in September 2019, will take course over the next three years. It is funded by the National Science Foundation (NSF) and the space stations U.S. National Laboratory.

TTUHSC El Paso faculty scientist Munmun Chattopadhyay, Ph.D., a researcher on the project, states:

Knowledge gathered from this study could be used to develop technologies and therapeutic strategies to better combat tissue atrophy experienced by astronauts, as well as open the door for improved treatments for people who suffer from serious heart issues due to illness.

How does microgravity affect our hearts?

Researchers taking part in the project are Dr. Chattopadhyay and UTEP biomedical engineer Binata Joddar, Ph.D. Dr. Chattopadhyay is an assistant professor in TTUHSC El Pasos Center of Emphasis in Diabetes and Metabolism, part of the Paul L. Foster School of Medicines Department of Molecular and Translational Medicine. Dr. Joddar is an assistant professor in the UTEP College of Engineering and leads research in the universitys Inspired Materials and Stem Cell-Based Tissue Engineering Laboratory.

Together, the researchers will collaborate to 3D bioprint small cardiac organoids using human stem cells. These heart-tissue structures will then be sent to the ISS, where they will be exposed to the near-weightless environment of the orbiting space station. The researchers hope that this will provide a better understanding of cardiac atrophy, which is a reduction and weakening of heart tissue, leading to difficulty pumping blood to the body. This condition commonly affects astronauts who spend long periods of time in microgravity, which causes significant problems as a weakened heart muscle can lead to symptoms such as fainting, irregular heartbeat, heart valve problems, and even heart failure.

Cardiac atrophy and a related condition, cardiac fibrosis, is a very big problem in our community. People suffering from diseases such as diabetes, muscular dystrophy and cancer, and conditions such as sepsis and congestive heart failure, often experience cardiac dysfunction and tissue damage, comments Dr. Chattopadhyay.

The first phase of the project will focus on research design. During this stage, taking place over the first year, Dr. Joddar will use 3D printing to fabricate the cardiac organoids. This will be achieved by coupling cardiac cells in physiological ratios to mimic heart tissue. Moving on to the second year, the researchers will be preparing the organoid payload for a rocket launch and mission in space. The third and final year of the project will center on analyzing the data from the experiment once the organoids have been returned to Earth.

Additionally, Dr. Chattopadhyay and Dr. Joddars project will provide an educational opportunity for the El Paso community. A workshop for K-12 students will be set up engaging young minds in the local area around the subject of tissue engineering, with focus placed on projects taking place on the space station. A seminar will also be provided for medical students, interns and residents to enable a discussion regarding the benefits and challenges of transitioning research from Earth-based laboratories into space.

3D bioprinting aboard the ISS

The TTUHSC El Paso and UTEP collaborative research project is one of just five research proposals selected by the NSF and ISS National Lab in 2019 as part of the organizations collaboration on tissue-engineering research funding. The NSF awarded Dr. Chattopadhyay $256,892 and Dr. Joddar $259,350 for their roles in the project.

A number of 3D bioprinting research projects have taken place aboard the ISS, as companies and organizations seek further understanding of how space flight affects astronauts.

For example, Russian bio-technical research laboratory 3D Bioprinting Solutions developed its Organ.Aut magnetic 3D bioprinter to study how living organisms are affected by long flights in outer space. In 2018, it was delivered to the ISS onboard the Soyuz MS-11 manned spacecraft following a previous failed launch from the Soyuz MS-10 spaceflight. In late 2019 it was announced that the company was able to 3D bioprint bone tissue in zero gravity aboard the ISS using the Organ.Aut. The experiment is part of a plan to create bone implants for astronaut transplantation during long-term interplanetary expeditions.

Additionally, the 3D BioFabrication Facility (BFF) bioprinter from nScrypt, a Florida-based 3D printing system manufacturer, and spaceflight equipment developer Techshot is also onboard the ISS. Delivered to the ISS aboard the SpaceX CRS-18 cargo mission in 2019, the system is capable of manufacturing human tissue in microgravity conditions. It was sent to the ISS in order to facilitate the production of self-supporting tissues that could lead to the development of therapeutic treatments.

El Paso scientists team up for heart research project at the International Space Station – KVIA El Paso

Posted: January 28, 2020 at 2:45 pm

EL PASO, Texas -- Biomedical research scientists from Texas Tech University Health Sciences Center El Paso and The University of Texas at El Paso are partnering up to send "artificial mini-hearts" to the International Space Station to better understand how microgravity affects the function of the human heart.

The three-year project, funded by the National Science Foundation (NSF) and the space station's U.S. National Laboratory, brings together TTUHSC El Paso faculty scientist Munmun Chattopadhyay, Ph.D., and UTEP biomedical engineer Binata Joddar, Ph.D. The researchers will collaborate in their Earth-bound labs to create tiny (less than 1 millimeter thick) heart-tissue structures, known as cardiac organoids, using human stem cells and 3D bioprinting technology.

By exposing the organoids to the near-weightless environment of the orbiting space station, the researchers hope to gain a better understanding of a health condition known as cardiac atrophy, which is a reduction and weakening of heart tissue.

A weakened heart muscle has difficulty pumping blood to the body, and can lead to problems such as fainting, irregular heartbeat, heart valve problems and even heart failure. Cardiac atrophy is also associated with chronic disease.

The first year of the project, which began in September, will focus on research design. During this phase, Dr. Joddar will use 3D printing to fabricate the cardiac organoids by coupling cardiac cells in physiological ratios to mimic heart tissue. The second year will be centered on preparing the organoid payload for a rocket launch and mission in space. The third and final year of the research will involve analyzing data from the experiment after the organoids are returned to Earth.

The project will also provide an educational opportunity for the El Paso community, with a workshop for K-12 students to learn about tissue engineering projects on the space station. It will also include a seminar for medical students, interns and residents about the benefits and challenges of transitioning research from Earth-based laboratories into space.

Blood drive to honor Franklin child with cancer – Daily Journal

Posted: January 27, 2020 at 11:53 pm

The tiny body seemed consumed by tubes and wires and monitors.

Just one day prior, Stephanie and Cody Smith had learned the terrible truth about why their 18-month-old son, Charlie, had been so sick recently. He had neuroblastoma, a cancer that forms on the nerve endings. Scans revealed cancer was on his kidney, lungs, bone and lymph nodes.

To stem the aggressive cancer, his doctors immediately got to work, putting in catheters, taking bone marrow biopsies and preparing for the start of intense chemotherapy. Charlie lay in his hospital bed eating Cheetos Puffs, his favorite food, and sitting with his parents.

"It was hard when we got the news," Stephanie Smith said. "I tried to be calm and collected; I had to be strong for my baby. But its been hard."

Story continues below gallery

The past two months have come straight out of a nightmare for the Smith family. Since Charlie was diagnosed with Stage IV neuroblastoma in November, each day brings uncertainty.

The Franklin family has spent 49 of the last 60 days at Riley Hospital for Children at IU Health. Charlie has gone through rounds of chemotherapy, suffering through fevers, mouth sores, extreme fatigue and nausea that wracked his small body. His treatment will last over the next 18 months, and will include chemotherapy, stem cell transplants, blood transfusions, radiation and immunotherapy.

But despite everything theyve been through, the Smiths remain resolute that Charlie will get better. They have relied on their faith, and an army of supporters who have stepped forward to help them in their worst time, to get them through.

"It was amazing to see so many people come up and love on us. It has taught us to be generous people; weve always thought we were generous people, but when you see the number of people who care for you and pray for you and support you, its really amazing," Stephanie Smith said.

The Smiths have partnered with Versiti Blood Center of Indiana to host a blood drive in Greenwood Saturday. The Cheering for Charlie event will be held from 6 a.m. to 2 p.m., to help increase blood supplies for patients such as Charlie who rely on transfusions to survive.

Every two seconds, someone needs life-saving blood, whether theyre bravely battling disease like Charlie, undergoing surgery or are victims of trauma," said Duane Brodt, spokesman for Versiti. "People need people since blood cant be manufactured."

For most of his life, Charlie was a happy-go-lucky toddler. He loved to smile and laugh, beaming joy. Where his 3-year-old brother Henry was more of a wild child, Stephanie Smith said, Charlie seemed to always be in a pleasant, good mood.

His parents described him as their "happy baby."

Thats what made his lethargy, lack of appetite and gradual decline in health so concerning.

"He was learning how to walk over the summer, and started getting sick," Stephanie Smith said. "We just thought it was a virus; we didnt think of the worst."

Charlie developed a low-grade fever, wasnt eating well and was falling asleep unexpectedly while playing with toys. He wasnt acting like himself, Stephanie Smith said.

During a visit to his pediatrician, the doctor found a hard area on Charlies abdomen, and recommended doing some blood tests and taking an X-ray. Those tests only led to more questions he had severe range anemia and elevated levels of platelets in his blood. But the doctor didnt have any conclusive answers as to what was causing it.

Stephanie Smith, a nurse at Franciscan Health, started hearing warning bells in her mind. That, combined with a mothers intuition, convinced her that they needed to take Charlie to Riley Hospital for Children. After 12 hours in the emergency room, and dozens of tests, doctors found a large tumor in Charlies abdomen.

"Sometimes, when kids are diagnosed with cancer, they can go home and be in and out of the hospital for treatment, but Charlie was really sick. The tumor was pushing on his kidney, damaging his kidney, so we had to stay in the hospital," Stephanie Smith said.

The pathology lab at Riley Hospital for Children confirmed the tumor was neuroblastoma. The cancer forms in immature nerve endings, often in the adrenal glands located near the kidneys and is most common in children age 5 and under, according to the American Cancer Society.

But the cancer is very rare; only about 800 new cases are diagnosed in the U.S. each year, according to the American Cancer Society.

Neuroblastomas grow and spread very rapidly, so treatment would have to be aggressive, doctors explained to the family. Charlies oncologist recommended starting with two rounds of focused chemotherapy, followed by the extraction of his red blood cells for stem cell transplants, then another three rounds of chemotherapy.

Two different stem cell transplants would be held about a month apart, and Charlie would start radiation treatment. Immunotherapy, which jolts the immune system into targeting and killing cancer cells, would be the final part of the regimen.

Almost immediately, Charlie started his chemotherapy.

"It grows so quickly, that we had to be aggressive. The beginning was pretty intense," Stephanie Smith said.

The treatment was hard on Charlies young body. He developed mouth sores and didnt want to eat, and his nausea left him miserable. The Smith family essentially relocated to the hospital, staying with him constantly.

But at the same time, their friends and family, as well as complete strangers, stepped up to offer help. A meal train was set up to provide the family with food, and prayers came from all directions.

A GoFundMe page has raised more than $36,000 for the family. A community Facebook page has more than 5,000 members.

"We had a rally of people come around us," Stephanie Smith said. "We couldnt have done it without all of the people who have come together."

Charlie has completed his first four rounds of chemotherapy, and on Jan. 20, he was able to return home with his family to wait for surgery to remove the tumor in his abdomen. That operation is tentatively going to be early to mid February.

In the meantime, the family has been soaking in the opportunity to be together somewhere besides the hospital. They have also been working to plan the blood drive being held on Saturday.

Charlie has relied on blood transfusions throughout his treatment, and a blood drive would be a way to raise awareness of the importance of those transfusions to cancer patients, Stephanie Smith said.

"Charlie received quite a few blood products, especially early on in his treatment. He had 12 transfusions in these 2 1/2 months. For his little body, thats a lot," she said. "Being a nurse, I didnt realize the number of cancer patients who need blood products. Its so important. So this was a way to let people know that."

Stephanie Smiths sister, Shelby Richards, knew people who had organized drives with their friends and helped the family get the Cheering for Charlie drive going.

The drive is a perfect opportunity to remind people that blood donations are vitally important, Brodt said. Versiti Blood Center of Indiana needs to collect at least 560 blood donations every day to support the need at its 80 hospital partners throughout the state, he said.

"So our Cheering for Charlie will truly make a difference and help save lives," Brodt said.

For the Smith family, the drive is a way to give back for all the love theyve been shown.

"Its really cool for us to see how many people have signed up, and also be advocates for other people who need blood, to just get the word out there about how important it is," Stephanie Smith said. "Its encouraging for us to see people come out to support Charlie and kids like him."

Scientists Have Grown Snake Venom Glands in The Lab. Here’s Why That’s Awesome – ScienceAlert

Posted: January 27, 2020 at 11:50 pm

For the first time, scientists have produced snake venom toxins in the lab, opening up a much-needed path for developing drugs and venom antidotes that doesn't involve having to breed and milk real-life snakes.

The toxins have been produced through mini glands called organoids, following a process adapted from growing simplified human organs something that is already helping in a wide range of scientific and medical research projects.

In the case of the snakes, researchers were able to blow organoids matching the Cape coral snake (Aspidelaps lubricus cowlesi) and seven other snake species, and they say this new approach is a welcome upgrade on current methods of farming snakes to extract their venom.

"More than 100,000 people die from snake bites every year, mostly in developing countries," says molecular biologist Hans Clevers, from Utrecht University in the Netherlands. "Yet the methods for manufacturing antivenom haven't changed since the 19th century."

By tweaking the recently developed process for growing human organoids including reducing the temperature to match reptiles rather than mammals the researchers were able to find a recipe that supports the indefinite growth of tiny snake venom glands.

Tissue was removed from snake embryos and put into a gel mixed with growth factors, but access to stem cells which is how human and mouse organoids are usually developed wasn't required.

The cells quickly began dividing and forming structures, giving the team hundreds of growing samples in the space of a couple of months, and producing small white blobs from which venom toxins could be harvested.

Al least four distinct types of cell were identified by the researchers within the artificially grown venom glands, and they were also able to confirm that the venom peptides produced were biologically active, closely resembling those in live snake venom.

"We know from other secretory systems such as the pancreas and intestine that specialised cell types make subsets of hormones," says developmental biologist Joep Beumerfrom Utrecht University.

"Now we saw for the first time that this is also the case for the toxins produced by snake venom gland cells."

The use of snake venom toxins to develop medicines and treatments has been going on since the time of ancient Greece. In the modern age, drugs fighting everything from cancer to haemorrhages have been developed with the help of toxins we find in snake venom.

Having faster and more controlled access to these toxins could mean these treatments can be developed more easily and on a shorter time scale, say the researchers.

Besides drug development, these organoid venom glands should make it easier and faster to develop antivenoms and with so many people suffering deaths, injuries or disabilities because of snake bites, that will make a considerable difference.

"It's a breakthrough," snake venom toxicologist Jos Mara Gutirrez from the University of Costa Rica, told Science.

"This work opens the possibilities for studying the cellular biology of venom-secreting cells at a very fine level, which has not been possible in the past."

The research has been published in Cell.

Weekly pick of brain tumour research news from around the world – Brain Tumour Research

Posted: January 27, 2020 at 11:50 pm

The first symposium of the South West Brain Tumour Centre was held on Thursday at Derriford Hospital in Plymouth. During a fascinating and very well attended event, topics covered included the mechanism of tumour development, new drug targets, new biomarkers and brain tumour imaging. The South West Brain Tumour centre is of course one of the UK Centres of Excellence funded by Brain Tumour Research.

A really big cancer wide story this week is here Immune discovery 'may treat all cancer' applicable to some solid tumours but not yet brain it really shows the direction of travel toward immunotherapy I have recommended this book before but if interested please do read The Breakthrough by Charles Graeber it is available on Amazon and you can read reviews here - http://www.charlesgraeber.com.Researchers uncover novel drug target for glioblastoma by revealing a cellular pathway that appears to contribute to glioma stem cell spread and proliferation. This pathway shows that glioma stem cells ability to access key nutrients in their surrounding microenvironment is integral for their maintenance and spread. Finding a way to interrupt this feedback loop will be important for treating glioblastoma.

An intelligent molecule could significantly extend the lives of patients with glioblastoma, research finds. The molecule, called ZR2002, which can be administered orally and is capable of penetrating the blood-brain barrier, could delay the multiplication of glioblastoma stem cells resistant to standard treatment. According to scientists in the Metabolic Disorders and Complications Program at the Research Institute of the McGill University Health Centre (RI-MUHC) the ZR2002 molecule is designed to kill two birds with one stone: on top of attacking the tumour, it destroys its defence system.

Researchers find clues to drug resistance in medulloblastoma subtype.US scientists have identified specific types of cells that cause targeted treatment to fail in a subtype of medulloblastoma. They found while the majority of cells responded to treatment, diverse populations within the tumour continue to grow leadingto treatment resistance. They concluded that the diversity of cells within tumours allow them to become rapidly resistant to precisely targeted treatments," and that due to this tumour cell diversity, molecularly precise therapies should be used in combinations to be effective."

Nanoparticles deliver 'suicide gene' therapy to paediatric brain tumours growing in mice So-called "suicide genes" have been studied and used in cancer treatments for more than 25 years. Researchers report here that a type of biodegradable, lab-engineered nanoparticle they fashioned can successfully deliver a ''suicide gene'' to paediatric brain tumour cells implanted in the brains of mice.

According to a study that uncovers an unexpected connection between gliomas and neurodegenerative diseases a protein typically associated with neurodegenerative diseases like Alzheimers might help scientists explore how gliomas become so aggressive. The new study, in mouse models and human brain tumour tissues, was published in Science Translational Medicine and found a significant expression of the protein TAU in glioma cells, especially in those patients with better prognoses. Patients with glioma are given a better prognosis when their tumour expresses a mutation in a gene called isocitrate dehydrogenase 1 (IDH1). In this international collaborative study led by the Instituto de Salud Carlos III-UFIEC in Madrid, Spain, those IDHI mutations stimulated the expression of TAU. Then, the presence of TAU acted as a brake for the formation of new blood vessels, which are necessary for the aggressive behaviour of the tumours.

'Innovative research award' helps Colorado scientists block brain cancer escape routes Cancers used to be defined by where they grow in the body - lung cancer, skin cancer, brain cancer, etc. But work in recent decades has shown that cancers sharing specific genetic changes may have more in common than cancers that happen to grow in an area of the body. For example, lung cancers, skin cancers, and brain cancers may all be caused by mutation in a gene called BRAF. Drugs targeting BRAF have changed the treatment landscape for melanoma, an aggressive form of skin cancer, and are also in use against lung cancers and brain cancers with BRAF mutations. It is really worth clicking through to read more on this and the ultimate goal of identifying new potential targets for combination therapy and new agents that could be added to BRAF inhibiting drugs in brain cancer to keep the cancer from developing resistance.
