First-ever captivity-bred bat colony to unlock secrets of behavior, cognition

Mysterious creatures that thrive in the dark, bats have long been associated with witchcraft, vampires, and black magic. But according to Dr. Yossi Yovel of Tel Aviv University's Department of Zoology at Tel Aviv University, we have much to learn from these highly intelligent winged mammals. Now he is developing the world's first bat colony born and raised in captivity to unlock the secrets of behavior and cognition, including social hierarchy and structure, communication abilities, and memory.

ACADI’s pimavanserin may have therapeutic benefits in treatment of ADP

ACADIA Pharmaceuticals Inc., a biopharmaceutical company focused on innovative treatments that address unmet medical needs in neurological and related central nervous system disorders, today announced results of preclinical studies, which suggest that pimavanserin, ACADIA's proprietary product candidate currently in Phase III development for Parkinson's disease psychosis, also may have therapeutic benefits in the treatment of Alzheimer's disease psychosis (ADP).

Scientists discover two key epigenetic regulating genes that govern stem cell differentiation

The ability to control whether certain stem cells ultimately become bone cells holds great promise for regenerative medicine and potential therapies aimed at treating metabolic bone diseases. Now, UCLA School of Dentistry professor and leading cancer scientist Dr. Cun-Yu Wang and his research team have made a significant breakthrough in that direction. The scientists have discovered two key epigenetic regulating genes that govern the cell-fate determination of human bone marrow stem cells.

MiR-33 plays a key role in regulating bile metabolism

In research funded by the National Institutes of Health and the American Heart Association and published in EMBO Molecular Medicine, Saint Louis University investigator -ngel Bald-n, Ph.D., found that the microRNA miR-33 plays a key role in regulating bile metabolism. Further, the research suggests that, in an animal model, the manipulation of this microRNA can improve the liver toxicity that can be caused by statins.

Researchers investigate whether PTSD is a brain disorder

Researchers at The University of Texas Health Science Center at Houston (UTHealth) are investigating whether post traumatic stress disorder (PTSD) is a brain disorder that can affect multiple parts of the body and cause lifelong illnesses.

Researchers discover mechanism that favours disappearance and inhibition of SCC development

Skin squamous cell carcinoma (SCC) is a subtype of very aggressive skin cancers that usually develops in sunexposed body regions, but can also affect a large number of organs such as the bladder, esophagus, lungs etc. However, little is known about the biology of these cells, which consequently makes difficult the generation of new specific therapies; actually, the standard treatments are based on surgery and subsequent radiotherapy.

Lipid ceramide helps cells keep cilium or antenna from retracting

A lipid that helps lotion soften the skin also helps cells find and stay in the right location in the body by ensuring they keep their "antennae" up, scientists report.

Glycemic index varies from one type of rice to another

Research analysing 235 types of rice from around the world has found its glycemic index (GI) varies from one type of rice to another with most varieties scoring a low to medium GI. This finding is good news because it not only means rice can be part of a healthy diet for the average consumer, it also means people with diabetes, or at risk of diabetes, can select the right rice to help maintain a healthy, low GI diet.

Scientists develop novel anticancer drug designed to travel through the bloodstream

Scientists at the Johns Hopkins Kimmel Cancer Center, working with Danish researchers, have developed a novel anticancer drug designed to travel -- undetected by normal cells -- through the bloodstream until activated by specific cancer proteins.

Disabling Nf1 gene makes stem cells from the third ventricle proliferate rapidly

Scientists showed in mice that disabling a gene linked to a common pediatric tumor disorder, neurofibromatosis type 1 (NF1), made stem cells from one part of the brain proliferate rapidly. But the same genetic deficit had no effect on stem cells from another brain region.

Methylation provides signal of unique mix of leukocytes

When a person is sick, there is a tell-tale sign in their blood: a different mix of the various types of immune cells called leukocytes. A group of scientists at several institutions including Brown University has discovered a way to determine that mix from the DNA in archival or fresh blood samples, potentially providing a practical new technology not only for medical research but also for clinical diagnosis and treatment monitoring of ailments including some cancers.

Oligomers may be responsible for onset of Alzheimer's

Alzheimer's disease is one of the most dreaded and debilitating illnesses one can develop. Currently, the disease afflicts 6.5 million Americans and the Alzheimer's Association projects it to increase to between 11 and 16 million, or 1 in 85 people, by 2050.

Sox10 gene plays a central role in melanoma

Black skin cancer, also known as melanoma, is particularly aggressive and becoming increasingly common in Switzerland. Despite intensive research, however, there is still no treatment. Researchers from the University of Zurich have now discovered a gene that plays a central role in black skin cancer. Suppressing this gene in mice inhibits the development of melanoma and its proliferation - a discovery that could pave the way for new forms of therapy.

MammaPrint more cost-effective and clinically-useful test than Oncotype DX

New research from University of the Sciences' Mayes College of Healthcare Business and Policy suggests that MammaPrint - a gene expression profiling (GEP) test used to identify whether women with early-stage breast cancer would benefit from chemotherapy - is the more cost-effective and clinically-useful test than the most frequently used GEP in practice in the United States today.

Measuring creatinine and cystatin C more accurately estimates kidney function

Measuring creatinine and cystatin C - two markers for chronic kidney disease (CKD) - more precisely estimates kidney function than either marker alone, according to a study funded by the National Institutes of Health. Results appear in the July 5 issue of the New England Journal of Medicine.

Combination of estrogen and MPA increases synapses in the prefrontal cortex

A new study of aged female rats found that long-term treatment with estrogen and a synthetic progesterone known as MPA increased levels of a protein marker of synapses in the prefrontal cortex, a brain region known to suffer significant losses in aging.
