Scientists at Kumamoto University have made a major breakthrough in regenerative medicine by successfully creating functional ureter tissue—organoids resembling the urinary tract—from pluripotent stem cells. The achievement brings researchers one step closer to developing transplantable kidneys capable of producing and expelling urine.
Kanishka Thiran Jayasundera has been appointed professor and chair of the Department of Ophthalmology and Vision Science. He comes to UC Davis from the University of Michigan’s Kellogg Eye Center.
Jayasundera is a leading expert on inherited retinal diseases. His clinical expertise and compassionate care have placed him at the forefront of vision restoration. He built his distinguished career by focusing on improving treatments and providing mental health support for patients with vision loss.
Next to cancer recurrence or progression, cardiovascular diseases are the leading causes of death in cancer survivors. The Surveillance, Epidemiology, and End Results database revealed that among the more than three million who initially survived cancer between 1973 and 2012, 38% eventually succumbed to the disease while 11.3% died from cardiovascular diseases. Specifically, cancer survivors are at a four to seven-fold higher risk of venous thromboembolism (VTE), which proves fatal in one out of seven cancer patients.
While the effects of high-fat diets have been studied in the context of cancer and cardiovascular disease, sparse information is available on the impact of a high-protein diet and cancer-associated thrombosis.
In a new study researchers have found that a high protein diet, or a diet high in amino acid tryptophan (Trp). Trp is abundant in various protein-rich foods increases the risk of cancer-associated VTE in experimental models.
The Cardiovascular Research Foundation® (CRF®) is excited to announce the late-breaking clinical trials and science set to be presented at TCT® 2025, the annual scientific symposium of CRF® and the world’s premier educational meeting specializing in interventional cardiovascular medicine. This year’s conference will take place October 25–28 at the Moscone Center in San Francisco, bringing together top experts, innovators, and clinicians from around the globe.
An interdisciplinary team has uncovered the first genetic evidence of the Plague of Justinian in the Eastern Mediterranean, reshaping the history of pandemics and our modern understanding of how pandemics emerge, recur and spread -- and why they remain a persistent feature of human civilization.
