The first side-necked turtle ever to be found in the UK has been discovered by an amateur fossil collector and palaeontologists at the University of Portsmouth. The fossil remains are the earliest of a so-called side-necked pan-pleurodiran turtle, named as such because they fold their neck into their shell sideways when threatened. This does mean they can only see out with one eye. Originally found on a National Trust beach on the Isle of Wight, the turtle fossil is an almost complete shell with cervical, dorsal and caudal vertebrae, scapulae, pelvic girdle and appendicular bones. Sadly, the skull was missing. Lead author, Megan Jacobs, ...

LOS ANGELES -- A new study from Keck Medicine of USC has uncovered significant racial disparities in the diagnosis, treatment and outcomes of peripheral artery disease (PAD) among Black and white patients in the United States.   PAD, which affects approximately eight to 12 million Americans and is associated with nearly half of the 150,000 yearly amputations in the U.S., is a potentially life-threatening condition in which the arteries that carry blood from the heart to the legs narrow or become blocked by the buildup of fatty plaque. This can lead to a heart attack, stroke or amputation of the affected limb.  “We discovered that Black patients are nearly 50% less ...

Following encouraging results from pre-clinical research and a recent clinical trial on stem cell-based treatments for patients with Type 1 diabetes, researchers are now working on maximizing the function and potential of stem cell-based treatments for future application in patients.    More than 8 billion people worldwide live with Type 1 diabetes (T1D) according to recent estimates. In T1D, the so-called beta cells in the pancreas do not make enough of the hormone insulin due to the destruction of beta-cells by the immune system leading to blood sugar levels rising above normal levels. Over time, T1D can lead to severe organ damage. There is no cure ...

Researchers have used heart and lung stem cells infected with the virus that causes COVID-19 to better understand how the disease impacts different organs, paving the way for more targeted treatments.

LA JOLLA (June 13, 2023)—The immune system protects the body from invaders, such as bacteria, viruses, or tumors, with its intricate network of proteins, cells, and organs. Specialized immune cells, called cytotoxic T cells, can develop into short-lived effector cells that kill infected or cancerous cells within our bodies. A small portion of those effector cells remain after an infection and become longer-lived memory cells, which “remember” infections and respond when infections reappear. ...

Most women diagnosed with early stage breast cancer today can expect to become long term cancer survivors, finds a study published by The BMJ today. The findings show that the average risk of dying from breast cancer in the five years after a diagnosis has fallen from 14% to 5% since the 1990s. For those diagnosed during 2010-15, more than six in 10 women had a five year risk of 3% or less. The researchers say their findings can be used to reassure most women treated for early breast cancer that they are likely to become long term cancer survivors. ...

June 13, 2023 – Enrollment in the Medicare Advantage program – which allows Medicare beneficiaries to get their health care through plans administered by private insurance companies – has been growing so rapidly that it has recently surpassed enrollment in traditional Medicare. A new analysis by USC researchers warns that overpayments to Medicare Advantage plans now exceed 20 percent or $75 billion annually, underscoring the urgent need for reform. Researchers with the USC Schaeffer Center for Health Policy & Economics found that the millions of beneficiaries in traditional Medicare who have switched to Medicare ...

Philadelphia, June 13, 2023 – Cognitive deficits accompany mood disorders and other psychiatric conditions, often with debilitating effects. Limited treatments currently exist, but studies in animals and humans have pointed to drugs such as the laxative prucalopride that activate serotonin receptors as a potential therapeutic for the symptoms. It has remained unclear, however, how the medication affects resting brain activity. Now, a new study in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging, published by Elsevier, examines the drug’s effects in healthy human adults. Serotonin receptors and the 5-HT4-type receptors in particular are found in areas ...

CD8+ T cells, a vital component of the immune system that provides immunity against cancer, have been the focal point of anti-cancer therapies. Recent studies have identified two major subpopulations of these cells present within the tumor—the stem-like cells that do not have anti-tumor activity, and the terminally differentiated CD8+ T cells, which are generated from the stem-like cells and have cytotoxic function on tumor cells. Tumor-draining lymph nodes (TDLNs) have been found to be the primary site for the presence of these cells. However, the molecular mechanisms responsible for the generation of stem-like cells into terminally differentiated ...
