Diabetes app forecasts blood sugar levels – Science Daily

Posted: April 28, 2017 at 1:49 am

Columbia University researchers have developed a personalized algorithm that predicts the impact of particular foods on an individual's blood sugar levels. The algorithm has been integrated into an app, Glucoracle, that will allow individuals with type 2 diabetes to keep a tighter rein on their glucose levels -- the key to preventing or controlling the major complications of a disease that affects 8 percent of Americans.

The findings were published online today in PLOS Computational Biology.

Medications are often prescribed to help patients with type 2 diabetes manage their blood sugar levels, but exercise and diet also play an important role.

"While we know the general effect of different types of food on blood glucose, the detailed effects can vary widely from one person to another and for the same person over time," said lead author David Albers, PhD, associate research scientist in Biomedical Informatics at Columbia University Medical Center (CUMC). "Even with expert guidance, it's difficult for people to understand the true impact of their dietary choices, particularly on a meal-to-meal basis. Our algorithm, integrated into an easy-to-use app, predicts the consequences of eating a specific meal before the food is eaten, allowing individuals to make better nutritional choices during mealtime."

The algorithm uses a technique called data assimilation, in which a mathematical model of a person's response to glucose is regularly updated with observational data -- blood sugar measurements and nutritional information -- to improve the model's predictions, explained co-study leader George Hripcsak, MD, MS, the Vivian Beaumont Allen Professor and chair of Biomedical Informatics at CUMC. Data assimilation is used in a variety of applications, notably weather forecasting.

"The data assimilator is continually updated with the user's food intake and blood glucose measurements, personalizing the model for that individual," said co-study leader Lena Mamykina, PhD, assistant professor of biomedical informatics at CUMC, whose team has designed and developed the Glucoracle app.

Glucoracle allows the user to upload fingerstick blood measurements and a photo of a particular meal to the app, along with a rough estimate of the nutritional content of the meal. This estimate provides the user with an immediate prediction of post-meal blood sugar levels. The estimate and forecast are then adjusted for accuracy. The app begins generating predictions after it has been used for a week, allowing the data assimilator has learned how the user responds to different foods.

The researchers initially tested the data assimilator on five individuals using the app, including three with type 2 diabetes and two without the disease. The app's predictions were compared with actual post-meal blood glucose measurements and with the predictions of certified diabetes educators.

For the two non-diabetic individuals, the app's predictions were comparable to the actual glucose measurements. For the three subjects with diabetes, the app's forecasts were slightly less accurate, possibly due to fluctuations in the physiology of patients with diabetes or parameter error, but were still comparable to the predictions of the diabetes educators.

"There's certainly room for improvement," said Dr. Albers. "This evaluation was designed to prove that it's possible, using routine self-monitoring data, to generate real-time glucose forecasts that people could use to make better nutritional choices. We have been able to make an aspect of diabetes self-management that has been nearly impossible for people with type 2 diabetes more manageable. Now our task is to make the data assimilation tool powering the app even better."

Encouraged by these early results, the research team is preparing for a larger clinical trial. The researchers estimate that the app could be ready for widespread use within two years.

New blood test may better predict gestational diabetes – Science Daily

Posted: April 28, 2017 at 1:49 am

A new study led by researchers at Brigham and Women's Hospital has found that a single measurement of plasma glycated CD59 (GCD59), a novel biomarker for diabetes, at weeks 24-28 of gestation identified, with high sensitivity and specificity, women who failed the glucose challenge test as well as women with gestational diabetes. Plasma levels of GCD59 were also associated with the probability of delivering a large-for-gestational-age newborn. These findings are published in Diabetes Care.

Gestational diabetes is a type of diabetes that occurs during a woman's pregnancy, increasing the mother's risk of delivering a large-for-gestational-age baby, which can lead to pre-term birth, fetal injury, perinatal mortality and cesarean delivery. Gestational diabetes is also a risk factor for preeclampsia and gestational hypertension. Since treatment of gestational diabetes can lessen the risk of adverse pregnancy outcomes, practice guidelines recommend screening all non-diabetic, pregnant women for the disease. The current standard of care to both screen and diagnose gestational diabetes predominantly involves a two-step approach. The first step, known as the glucose challenge test, includes administration of a sugary drink followed by a blood sugar measurement one hour later. Women who fail this screening are then sent for a longer test, called the oral glucose tolerance test, which requires fasting overnight, drinking a more concentrated sugar solution and undergoing baseline and hourly blood draws for three hours. These glucose tests, or variations thereof, are currently the only methods used to screen pregnant women for or diagnose gestational diabetes. They are time consuming, cumbersome, uncomfortable for mothers and have poor reported reproducibility.

The research team's primary goal was to assess the accuracy of the diabetes biomarker, GCD59, in predicting the results of the standard of care glucose challenge test used to screen for gestational diabetes. The team conducted a case-control study of 1,000 pregnant women who were receiving standard prenatal care at BWH: 500 women who had a normal glucose challenge test (control subjects) and 500 women who failed the glucose challenge test and required a subsequent oral glucose tolerance test (case patients). Researchers found that, when compared with the control subjects, the median plasma GCD59 value was 8.5-fold higher in the patients who failed the glucose challenge test and 10-fold higher in the subset of these patients who met diagnostic criteria for gestational diabetes in the subsequent oral glucose tolerance test.

"This is the first study to demonstrate that a single measurement of plasma GCD59 can be used as a simplified method to identify women who are at risk for failing the glucose challenge test and are at higher risk for developing gestational diabetes," says Jose Halperin, MD, a physician and researcher, Director of the Hematology Laboratory for Translational Research at BWH and senior author of the publication.

The researchers also found that higher plasma GCD59 levels at gestational week 24-28 were associated with higher prevalence of large-for-gestational-age newborns, with the higher the level, the higher the risk (4 percent higher risk for patients in the lowest quartile of GCD59 plasma levels, and 14 percent in the highest quartile). Out of the 58 large-for-gestational-age babies born to mothers that failed the glucose challenge test in this study, 80 percent were born to mothers who did not meet oral glucose tolerance test criteria for gestational diabetes, but had median plasma GCD59 levels 7-fold higher than control women with a normal glucose challenge test. These findings are consistent with other studies showing that women who fail the glucose challenge test, but do not meet criteria for gestational diabetes, are still at a higher risk of abnormal pregnancy outcomes, including delivering large for gestational age babies. Currently there are no practice guidelines for the management of women who fall between normal and abnormal glucose tolerance levels, and, therefore, their management is the same as that for women with a normal glucose challenge test results.

"These results suggest that a single measurement of plasma GCD59 during weeks 24-28 may also help stratify the risk for delivering larger infants among women with gestational glucose intolerance." says Halperin. "Our studies opened an avenue for larger multicenter studies to further assess the clinical utility of plasma GCD59 for screening and diagnosis of gestational diabetes among the general population of the United States. If our results are confirmed, we're hopeful that the GCD59 test could be available in clinical practices within the next few years."

Smartphone App Enables Wireless Control of Diabetes – Genetic Engineering & Biotechnology News

Posted: April 28, 2017 at 1:49 am

Imagine taking out your smartphone and asking, Can you control my blood sugar now? Ideally, you wouldnt even have to askif the smartphone were part of a loop that wirelessly connected your glucometer and an implanted population of cells engineered to secrete insulin on demand.

Such a setup, assembled by scientists based at the Shanghai Key Laboratory of Regulatory Biology, was recently shown to keep blood sugar levels within normal limits in diabetic mice. Details of this work, a synthetic biology tour de force, appeared April 26 in the journal Science Translational Medicine, in an article entitled Smartphone-Controlled Optogenetically Engineered Cells Enable Semiautomatic Glucose Homeostasis in Diabetic Mice.

Using a multidisciplinary design principle coupling electrical engineering, software development, and synthetic biology, we have engineered a technological infrastructure enabling the smartphone-assisted semiautomatic treatment of diabetes in mice, wrote the articles authors. A custom-designed home server SmartController was programmed to process wireless signals, enabling a smartphone to regulate hormone production by optically engineered cells implanted in diabetic mice via a far-red light (FRL)responsive optogenetic interface.

Essentially, the researchers added the cells to a soft biocompatible sheath that also contained wirelessly powered red LED lights to create HydrogeLEDs that could be turned on and off by an external electromagnetic field. Implanting the HydrogeLEDs into the skin of diabetic mice allowed the researchers to administer insulin doses remotely through a smartphone application. When the cells in the hydrogel were stimulated by the red LED lights, they produced a short variant of human glucagon-like peptide 1 (shGLP-1) or mouse insulin.

The scientists, led by Haifeng Ye, Ph.D., not only custom-coded the smartphone control algorithms, but also designed the engineered cells to produce insulin without any "cross-talk" between normal cellular signaling processes. The scientists went on to pair the system with a Bluetooth-enabled blood glucose meter, creating instant feedback between the therapeutic cells and the diagnostic device that helped diabetic animals rapidly achieve and maintain stable blood glucose levels in a small pilot experiment over a period of several weeks.

In vivo production of shGLP-1 or mouse insulin by the engineered cells in the hydrogel could be remotely controlled by smartphone programs or a custom-engineered Bluetooth-active glucometer in a semiautomatic, glucose-dependent manner, the authors continued. By combining electronic devicegenerated digital signals with optogenetically engineered cells, this study provides a step toward translating cell-based therapies into the clinic."

Local nonprofit gets grant to help uninsured diabetes patients – Nooga.com

Posted: April 28, 2017 at 1:49 am

A local organization recently got a grant to help area residents who have diabetes. (Photo: Contributed)

A local nonprofit just landed a $35,000 grant to create a nutrition and wellness program that will help people with diabetes who don't have access to health insurance.

Volunteers in Medicine Chattanooga, a free clinic thatprovides primary and preventive health care to financially eligible individuals and families who don't have insurance,was one of 33 organizations across the country to be awarded a CVS Health Foundation Grant.

More information

The organization serves people between the ages of 19 and 64 who are at or below 200 percent of the federal poverty level.

Services are provided by licensed medical professionals who donate their time without charge to Volunteers in Medicine Chattanoogapatients.

For more information about how to start the program, click here, call 423-855-8220 or go by the clinic, which is located at 5705 Marlin Road, Suite 1400.

"We are thrilled to be recognized by the CVS Health Foundation as a recipient of a CVS Health Foundation Grant," Executive Director Ashley Evans said. "The foundations support makes it possible for our organization to continue helping our diabetic patients manage this chronic disease."

If left untreated, diabetes can cause the loss of limbs, blindness and kidney failure, she said.

But many of the organization's patients ignore chronic conditions because they don't have the resources to make it to appointments.

In 2016, the organization treated more than 100 patients with diabetes through medication oversight, diet plans and quarterly education talks.

Of those patients, about 70 percent maintained or reduced their blood sugar to normal levels.

The grant will be used to develop, implement and evaluate a lifestyle education program specifically to help patients prevent, reverse and manage diabetes.

It will allow the organization to work with 60 patients and do a 21-day food program in which the participants stay on a plant-based diet. The organization will provide lunch and dinner to participants for the 21 days. That will be coupled with weight loss and nutrition classes, as well as health screenings.

"I don't expect a lot of people will stick with being completely vegan after this, but ... [we're hoping] that when people see they've lost weight and their diabetes might be completely under control that will make an impact on them," Evans said.

The program is set to start in May.

Miss Michigan raising awareness about diabetes – Fox 2 Detroit

Posted: April 28, 2017 at 1:49 am

(WJBK) - In just over two weeks, Miss Michigan Krista Ferguson will be traveling to Las Vegas to compete for the title of Miss USA.

While she has the spotlight, she's using the attention to raise awareness about diabetes. She was diagnosed with Type 1 diabetes two years ago.

Type 1 diabetes, also known as juvenile-onset, is where the body's immune system destroys the cells that release insulin, versus Type 2 diabetes in which your body can't use insulin the right way. Type 2 typically develops in adulthood.

Krista is giving herself about four shots every day, as well as pricking her finger multiple times to check her blood sugar. She also keeps a patch on her leg that continuously checks her blood sugar, and she gets alerts on her phone if her levels are changing too quickly.

Krista wants others to know that your illness doesn't define you.

"It may be a part of you but it will never stop you from conquering your dreams and achieveing your goals," she says.

You can watch Krista compete in the Miss USA competition right here on FOX 2 on May 14, 2017 at 7 p.m.

LONDON, April 27, 2017 /PRNewswire/ -- Diabetes management is on the verge of being disrupted by innovative technologies such as artificial pancreas, non-invasive glucose monitoring sensors, wearables, apps, and inhalable insulin. This research study captures all the innovative developments across the segments of wellness, diagnosis, monitoring, and therapy of the diabetes care continuum, covering the global market.

Download the full report: https://www.reportbuyer.com/product/4842301/

Diabetes remains one of the top causes of mortality, and health expenditure on the disorder and its complications is set to rise 19% annually until 2040, to reach $802 billion. Beyond the traditional focus and high-interest areas of monitoring and therapy, rising diabetes prevalence and costs are resulting in the focus gradually shifting to preventing diabetes, and on the overall wellbeing of diabetics and pre-diabetics, resulting in the highest double-digit growth of the wellness segment. Diagnosis, however, remains a neglected aspect of diabetes and novel approaches may be necessary to improve screening and diagnosing patients earlier to save on long-term costs. Monitoring developments that help improve the quality of life of diabetics include blood glucose monitoring tech advances (traditional glucometers and also semi-invasive, implants, and non-invasive continuous glucose monitoring systems), data analytics support, care delivery support, and overall diabetes management support in the form of apps, telehealth, and insulin dosing calculation support. Therapy, the largest segment, is also seeing several improvements in terms of better drugs, combination drugs, better insulin forms, and better delivery mechanisms. Of course, the main development in this segment is that of artificial pancreasthere is one commercially available system and several being developed with varying approaches and features. The other notable "permanent cure" approach is cell therapy involving regenerative medicine techniques with variations in the approaches for transplantation.

The study provides an exhaustive coverage of the overall diabetes ecosystem, with strong focus on startups, apart from the existing stakeholders. It also analyzes the role that technology giants such as Alphabet (ne Google) and IBM are playing in the diabetes space. An overview of several innovative diabetes care delivery models from across the world is also included. The study would be valuable for diabetes stakeholders to chart out their strategies for future collaborations and partnerships, while keeping a watchful eye on the competition.

Key questions this study will answer: How is the diabetes burden evolving across the globe? How are market forces and trends shaping the diabetes market and the segments of wellness, diagnosis, monitoring, and therapy? What gaps in diabetic care need to be filled to address the unmet needs of diabetics? What are the technological developments in the industry that attempt to address such unmet needs? How have some care models perfected diabetes management, catering to local needs? What are some future perspectives for the industry?

Andrews Institute Looks Ahead – Inweekly

Posted: April 27, 2017 at 10:47 am

By Duwayne Escobedo

At a recent press conference in honor of his facilitys 10th anniversary, Dr. James Andrews told the story about the moment he knew the Andrews Sports Medicine and Orthopaedic Center partnership with Baptist Health Care would happen.

Baptist Health Care brought its top executives to approach him for a second time in December 2003 about teaming up to start a sports medicine medical center in Gulf Breeze. He had just finished surgery at his Birmingham, Ala., center and welcomed the group into a small adjacent office.

Baptist Health Care CEO, Al Stubblefield envisioned building the Andrews Institute next to Gulf Breeze Hospital and providing its world-class medical care to the community. He was told about Andrews and his celebrity as a top sports orthopaedic surgeon. Stubblefield said, I dont know what an athletic trainer is, but I want some.

However, other Baptist officials werent convinced, especially Baptist Chief Financial Officer Joe Felkner.

During a tour of the Andrews sports medical center in Alabama, Felkner spotted USA Olympic gymnast Blaine Wilson doing rehab on an injured shoulder. Wilson grew up in Columbus, Ohio, and starred on Ohio States gymnastics team. Felkner was a big Buckeyes fanatic.

It was a damn miracle, Andrews said. He always played the bad guy. But right away he said, We got to do this. Thats really how we got the financing done.

A decade later, Andrews Institute in Gulf Breeze has made a huge impact on the Florida Gulf Coast region. It is estimated to have an economic impact on the region of tens of millions of dollars. The cutting-edge, world-renowned sports medicine center celebrated its achievements at its 10th anniversary Wednesday in the Andrews Athletic Performance and Research Pavilion.

Its been a magnificent journey for all of us, said Andrews, who thanked local government officials, Baptist executives, his team of more than 50 physicians, and wife, Jenelle. He also singled out longtime friend Jerry Pate and Ed Gray for securing funding from then-Governor Jeb Bush that helped make the Florida center a reality.

The funding allowed Andrews Institute to open the doors to its 126,535-square-foot sports medicine center in April 2007 that feels more like an upscale, luxurious hotel than a hospital. It features an ambulatory surgery center, an athletic performance center, and a research and education center.

Over its first 10 years, Andrews Institute performed more than 6,000 surgeries, provided athletic trainers freely to 25 public high schools from Escambia to Walton County and three area colleges, trained 57 fellows under its top-notch physicians, and worked to develop the next generation of sports medicine tools at its Regenerative Medicine Center.

Not only did it look back at its achievements at the press conference, the sports medicine center looked forward to what the next decade might hold for the institute.

One promising development is the use of stem cells to help speed up the healing process, regenerate tissue, cartilage and organs and lead to other cures for diseases, such as diabetes, arthritis and osteoporosis.

Dr. Adam Anz, an Andrews orthopaedic surgeon and sports medicine specialist, is overseeing a stem cell study that starts in May. He said stem cells are five to seven years away from earning FDA approval for medical uses and becoming widely used to treat patients. Stem cells are considered the biggest advance in sports medicine since arthroscopy surgery, which allows physicians to make a small incision on a patient and use a tiny camera to surgically repair knees, rotator cuffs, and other common debilitating sports injuries.

Anz talked excitedly about regenerative medicine. Today, bone marrow aspiration typically produces about 17,000 stem cells, while140 million stem cells come from a variety of regenerative sources, such as embryos, gestational and adult tissues, and reprogrammed differentiated cells.

The FDA is a lot like the IRS, Anz explained. We need to refine and prove to them that they work. There are future products, and they need development.

Andrews agreed. He said: Were still at the tip of the iceberg. Its coming though. Regenerative medicine will revolutionize not only what we do in sports medicine but all surgeries.

Another impact that Andrews Institute has had on the region is its sports medicine outreach to youth. The public service ensures sports medicine coverage freely to all of the public high schools in Escambia, Santa Rosa, Okaloosa and Walton counties and has plans to expand to other Northwest Florida counties, including Bay County. It includes performing baseline concussion tests for more than 4,500 youth athletes since 2015.

Only 37 percent of public high schools have a full-time athletic trainer, reports the NATA Research and Education Foundation.

Andrews led a charge in 2015 in the Florida Legislature to require all Florida High Schools to have at least one athletic trainer. But the legislation never passed.

Its getting to where it will be a medical legal issue, Andrews predicted. Right now my passion is youth sports.

Dr. Roger Ostrander was one of the first orthopaedic surgeons to relocate to Gulf Breeze in July 2004.

When I got here in 2004, I didnt understand the scope and magnitude of this project. Its unique in the country, Ostrander said. I feel very fortunate to be part of Andrews Institute from the beginning.

Andrews Institute By the Numbers 2007-2017 650,000+ Visits to Andrews Institute Rehabilitation location since 2008 61% Increase in patient volume since 2008 228,000+ X-ray and MRI exams completed since 2007 50,864 Patients/Cases seen at the Andrews Institute Ambulatory Surgery Center 303% Increase in patient volume since 2007 20,000 Free pre-participation exams performed 68,500 Injury assessments performed 1,800 Injury assessments performed at Saturday morning Student-Athlete Injury Clinic 4,500 Concussion baseline tests performed since 2015 400 Community events with Andrews Institute sports medicine coverage 84 Clinical research studies conducted over the last 10 years 19 Open clinical research studies from July 2015 to June 2016 112 Wounded or injured Special Operations military members treated from July 2015 to June 2016

UMN research team fixes broken hearts with 3D-printed tissue patch – Minnesota Daily

Posted: April 27, 2017 at 10:47 am

A research team at the University of Minnesota found a way to heal broken hearts.

Researchers used a 3D printer to create protein patches that mimic heart tissue to treat post-heart attack scars. The research is in collaboration with the University of Wisconsin-Madison and the University of Alabama-Birmingham.

Brenda Ogle, a University biomedical engineering professor and lead researcher for the project, said she and her team have investigated proteins that surround cells in the body for 15 years. The team has been studying how the proteins also called the extracellular matrix influence stem cell behavior.

For many years, weve been trying to develop optimum formulation that can support stem cells in new cardiac [cell] types, Ogle said, adding that theyve focused on cardiac cell types to figure out a way to strengthen them after the muscle cells are damaged and die during a heart attack. Its one of the cell types in the body that cant be recovered.

The team successfully treated mice with the patches and is now planning to test the method on larger animals.

Molly Kupfer, a doctoral student who is part of Ogles team, said a heart attack occurs when there is a blockage in a primary blood vessel that delivers oxygen and nutrients to the heart.

When that happens, you have cell death in the area of the heart that doesnt receive the appropriate oxygen and nutrients, Kupfer said. Those cells that die arent able to recover."

Typically, after a heart attack, the blood clot in the heart is removed at a hospital, and if the heart has not been damaged too badly, doctors monitor the heart long-term, prescribe medicine and regularly check for signs of heart failure, Ogle said.

What you get instead after a heart attack is scar tissue forming, and that scar tissue ultimately fails, Ogle said.

Associate Professor Brenda Ogle places a 3D printed biopatch on a mouse heart in Nils Hasselmo Hall on Tuesday, April 25, 2017. Her research team induces heart attacks in mice, which causes a dead area of cardiac cells. The patch is placed in this dead zone and mimics the cells of the native heart that aren't able to be replenished on their own.

Kupfer said she worked with Paul Campagnola and his lab at the University of Wisconsin to print the patches; the cells were prepared at the University of Minnesota.

Campagnola, a biomedical engineering professor, said he initially developed the underlying printing technology in 2000.

"The idea of the patch is it could actually behave like native cardiac tissue and assist the function of the heart, Kupfer said, adding that the method used to print the patches results in extremely high resolution structures.

Ogle said before applying the patch to the animal hearts theyre currently testing on, they take a scan of the scarred tissue and create a digital template for the 3D-printer to follow and print the proteins in the same pattern.

Campagnola said the patch provides a stable space for cells to grow and be implanted in damaged areas.

Cardiac cells are also added to the patch when it covers a damaged area. Ogle said it not only provides a support structure, but transplants healthy cells that will eventually become integrated into the heart, stabling it structurally and functionally.

A huge aha moment was when [the cardiac cells] started to beat on this patch synchronously and spontaneously, she said. When that happened, we realized that this could be a viable therapy for the heart, a way to replace those lost muscle cells.

Through the research group at the University of Alabama, Ogle said a study was conducted where the patch was tested on dead or dying tissue in mice hearts and the group saw improvement in the mice after four weeks.

The project was funded through a series of grants from the National Institutes of Health, the National Science Foundation with support from the University, she said.

The group has since received larger funds from the NIH to run a study using the patch on larger animals within the next year.

Ogle said it would take about 10 years until the patch can be used on human patients in a clinical setting.

Bengals set to hold onto McCarron for at least 1 more year | Sports … – Newsexaminer

Posted: April 27, 2017 at 10:47 am

CINCINNATI Bengals backup quarterback AJ McCarron is looking at another year of barely getting on the field, and maybe longer.

With the draft a few days away, Cincinnati has given no indication its willing to trade him to a team that would give him a bigger role. Its a challenging situation for McCarron, who proved he could lead a team into the playoffs in 2015 if given the opportunity.

As a competitor, you always want your chance to play, McCarron said Monday. But it will happen. I just have to wait my time. I believe that, and I trust in my ability to keep showcasing what I can do and then get my opportunity.

The two-time national champion at Alabama got his chance when Andy Dalton broke the thumb on his passing hand late in the 2015 season. McCarron, a fifth-round pick, started the last three games and won two of them. His late touchdown pass to A.J. Green had Cincinnati ahead in the closing minutes of a playoff game against Pittsburgh before a pair of defensive penalties helped the Steelers move in range for the winning field goal.

Last year, he was relegated to a backup role again, getting into only one game without throwing a pass.

Although theres great demand in the NFL for starting quarterbacks, the Bengals havent shown an inclination to trade him. Theyre content having him as the backup in case Dalton gets hurt again.

Its great to be wanted, it really is, McCarron said.

Even so, its difficult to go back to being the backup after leading a team to the playoffs. Dalton has been extremely durable during his six-year career the broken thumb was his only significant injury so the odds are against McCarron getting much chance to play until his contract ends.

Hes in a situation similar to Jimmy Garoppolo in New England, which hasnt shown an inclination to trade Tom Bradys backup.

McCarrons original deal runs through this season, but theres a catch. He showed up for training camp with a sore shoulder as a rookie in 2014 and was unavailable for most of the season, which could affect his status. Instead of being an unrestricted free agent, the Bengals think he should be a restricted free agent after the 2017 season because he missed most of his rookie season.

As a restricted free agent, McCarron could wind up spending the 2018 season in Cincinnati as well.

Were still going through all that, McCarron said. And its probably going to go into next year. Its just something theyre going to fight on their side and something Im going to fight on my side to prove why I shouldnt have to have another year.

McCarrons eagerness to move into a starters role is tempered by his appreciation for how the Bengals drafted him. They stuck with him after he missed most of his rookie season because of the sore shoulder, which improved after he got stem cells injected. In a year or two, hell get his chance.

There were some quarterbacks that got some pretty nice pay days this offseason, McCarron said. Hopefully in my future, one of those days is coming up.

Testing putative therapeutics

SS: Please tell us about your marine compounds project that you are working on, and the main challenges involved?

EK: We are currently looking into how marine compounds influence the mineralization in a murine chondrocyte cell line (ATDC5). The aim of the project is to test putative therapeutics, to improve joint health. Specifically, we are interested in seeing how they affect differentiation of these cells.

SS: Which methods do you use to investigate this project and how does the BioTek Cytation 5 play a part in this?

EK: We are exposing the cells to different concentrations of fractionated marine compounds in a 96-well microplate format. After 24 days of incubation we stain the cells both with calcein and Alizarin Red to quantify calcium deposition. This is when the Cytation 5 from BioTek comes in: we have a workflow set up that images (magnification 4x) each well in phase contrast and fluorescence (we are using a GFP filter cube for this assay), and also carries out a read of the fluorescence signal. We then perform the Alizarin Red staining, take more pictures and extract the bound color after several washing steps. A further reading step quantifies the Alizarin Red using an absorbance read.

The figure below shows an example read of the calcein stain: first picture, phase contrast, second picture, fluorescence channel (GFP filter cube) and the third picture, overlay of both:

SS: What are your main research findings so far?

EK: We have identified several possible inhibitors of mineralization, but we are still in the process of improving the assay protocol to make the quantification of the mineralization more reproducible. The Alizarin Red stain has proven to represent more accurate calcium deposition into the cells, when testing the assay protocol using standard inhibitors like levamisole, so we are using the calcein stain to visualize mineralization, and Alizarin Red to quantify.

SS: What is the future of your research?

EK: We are looking into setting up assays investigating blood pressure. Our project partner developed a product line based on fish protein hydrolysate using trimmings from cod (Gadus morhua). The proteins are extracted and broken down to smaller peptides that have been shown to inhibit a key enzyme involved in increasing blood pressure (ACE). For this research we will develop and perform cell-based assays.
