Possible new route to regenerating function lost in diabetes
In people with type I diabetes, insulin-producing beta cells in the pancreas die and are not replaced. Without these cells, the body loses the ability to control blood glucose. Researchers at the University of California, Davis have now discovered a possible new route to regenerating beta cells, giving insight into the basic mechanisms behind healthy metabolism and diabetes. Eventually, such research could lead to better treatment or cures for diabetes.
Nutritionist Looks at Fortifying Staple Foods To Boost Health
By Lisa Howard
Reina Engle-Stone was halfway through her biology degree at Cornell University when she discovered global nutrition.
Her introduction was a nutritional epidemiology class, and almost immediately she was hooked. “You could take biology and apply it to other things. I thought, this is great, this is what I want to do,” she says.

Two UC Davis graduates have started a company incubated in the TEAM manufacturing facility at the UC Davis Department of Biomedical Engineering.
Arshia Firouzi and Gurkern Sufi met in 2011 as Freshmen living in Tercero Dormitories at UC Davis and quickly became friends. Arshia majored in Electrical Engineering and Gurkern in Biotechnology, and they worked with the mentorship of Professor Marc Facciotti to explore their shared interest in the intersection of electronics and biology. In 2015 they won a VentureWell grant for a research project, which they pursued in TEAM’s Molecular Prototyping and Bioinnovation Laboratory. By the end of their project, they had come up with an idea that grew into a company that could usher in a new era for laboratories all over the world.

The successful application of an alternative male contraceptive in rhesus macaque monkeys at the California National Primate Research Center is paving the way for human clinical trials.
For over a century, men who did not want to father a child had only one permament option for contraception. But according to the results of a study conducted at the California National Primate Research Center (CNPRC), there could be an alternative to a vasectomy that is as efficient and has the potential to be easily and successfully reversible.

A UC Davis-led study of nursing mothers in The Gambia shows how environment changes breast milk content
In a newly published study, UC Davis researchers and their colleagues, paint the picture of an elegant web of cause-and-effect that connects climate, the breast milk of nursing moms, gut microbes and the health of breast fed infants.
The research is part of a long-running. cross-disciplinary project at UC Davis studying milk and its role in nutrition. For example, last year UC Davis scientists and colleagues at Washington University St. Louis worked with both children and animal models to show how milk compounds could alter gut microbe composition and affect health. UC Davis researchers also led a consortium to study the “milk genome,” the collection of all genes related to producing milk.

For all the moms who obediently popped their prenatal vitamins during pregnancy while wondering if the supplements could actually benefit their babies, an international research group has the answer, and it’s a resounding “yes.”
In fact, in a recent study the researchers discovered children whose mothers took multi-micronutrient supplements during pregnancy were advanced in cognitive abilities by as much as one full year of schooling by age 9-12 years.
The study, conducted in Indonesia and published Jan. 16 in the journal Lancet Global Health, also indicated that other essential ingredients in the recipe for smarter kids include early-life nurturing, happy moms, and educated parents.
Event Includes Horse Therapies For First Time

Four UC Davis researchers with expertise in the application of stem cell science for therapies in human or veterinary medicine are slated to speak during the World Stem Cell Summit in Palm Beach, Florida, Dec. 6-9.

This will be the 12th consecutive year that the summit has brought together scientists, physicians and veterinarians, industry representatives and patient advocates from around the world to share medical breakthroughs in stem cell research, also known as regenerative medicine.
Today’s White House announcement of the National Microbiome Initiative will bring new funding and attention to better understand the billions of microbes that swarm around in and around us and probably play an important role in our health, food and environment. At UC Davis, many scientists are already exploring this hidden world. Here are a few of them.
Jonathan Eisen is one of the pioneers of studying microbe communities through genetic sequencing. His lab is involved in understanding the complete “Tree of Life,” and projects on microbial communities associated with buildings, as well as communities on different plants and animals, including people, dogs and cats. A prolific blogger, Eisen regularly calls out examples of excessive microbiome hype.

Antibiotics are essential for fighting bacterial infection, but they can also make the body more prone to infection and diarrhea. Exactly how do antibiotics foster growth of disease-causing microbes – and how can resident “good” microbes in the gut protect against pathogens, such as Salmonella?
Now research led by Andreas Bäumler, professor of medical immunology and microbiology at UC Davis Health System, has identified the chain of events that occur within the gut lumen of mice after antibiotic treatment that allow “bad” bugs to flourish.

The curtain cloaking how AIDS and HIV (human immunodeficiency virus) impact the human digestive and immune systems has been drawn back a bit further, thanks to a team of researchers from UC Davis’ departments of Food Science and Technology and Medical Microbiology and Immunology.
The small intestine is extremely difficult to study because of its location in the body but plays a critical role in human health. Its inner lining offers both a portal for absorbing nutrients and a barrier against toxins or invasive microbes.
