Chicken eggs can provide better understanding of human birth defects

Clemson University researchers found that chicken eggs can provide a better understanding of human birth defects. Susan Chapman, associate professor in Clemson's College of Agriculture, Forestry and Life Sciences, received a South Carolina IDeA Networks of Biomedical Research Excellence award that allowed researchers to identify two regions in the chicken genome that are associated with congenital deafness and spine deformities in humans.

PCBs banned by the US 3 decades ago hurt seniors' cognitive performance

Although PCBs have been banned in the United States since 1979, University of Montreal and CHU Sainte-Justine researcher Maryse Bouchard has found that higher levels of the toxin was associated with lower cognitive performance in seniors.

Waseda University researchers observe molecular motors that play critical role in chromosome transport

Researchers at Waseda University in Japan have for the first time directly observed the “molecular motor”, called Xkid, that plays a critical role in facilitating the proper alignment of chromosomes during cell division. Their findings are expected to contribute greatly to elucidating the molecular mechanisms of chromosome segregation, a key aspect of the development of certain medical disorders including cancer and birth defects.

CRISPR-Cas-system: A promising tool for genetic engineering

Viruses cannot only cause illnesses in humans, they also infect bacteria. Those protect themselves with a kind of 'immune system' which - simply put - consists of specific sequences in the genetic material of the bacteria and a suitable enzyme. It detects foreign DNA, which may originate from a virus, cuts it up and thus makes the invaders harmless.

Research: Notch protein plays essential role in triggering T-cell development

The lab of Avinash Bhandoola, PhD, professor of Pathology and Laboratory Medicine, has studied the origins of T cells for many years. One protein called Notch, which has well-known roles in the development of multiple tissues, plays an essential role in triggering T-cell development.

Researchers identify immune cell protein that sets off body's initial response against viral infection

A Massachusetts General Hospital-led research team has identified an immune cell protein that is critical to setting off the body's initial response against viral infection. The report that will be published in an upcoming issue of Nature Immunology and is receiving early online release describes finding that a protein called GEF-H1 is essential to the ability of macrophages - major contributors to the innate immune system - to respond to viral infections like influenza.

Researchers discover how type 2 diabetes drug metformin actually works

Researchers from St. Vincent's Institute of Medical Research in Melbourne, Australia, in collaboration with researchers at McMaster University in Canada, are reportedly the first to discover how the type 2 diabetes drug metformin actually works, providing a molecular understanding that could lead to the development of more effective therapies. Mass spectrometry technologies from AB SCIEX, a global leader in analytical technologies, played a critical role in the analysis that led to this breakthrough finding.

Super cocktail of six natural compounds killed 100% of breast cancer cells without toxic side effects

A study led by Madhwa Raj, PhD, Research Professor in Obstetrics and Gynecology at LSU Health Sciences Center New Orleans and its Stanley S. Scott Cancer Center, has found that a super cocktail of six natural compounds in vegetables, fruits, spices and plant roots killed 100% of sample breast cancer cells without toxic side effects on normal cells.

Study may shed light on neural regrowth in mammals after spinal cord injury

Fish, unlike humans, can regenerate nerve connections and recover normal mobility following an injury to their spinal cord. Now, University of Missouri researchers have discovered how the sea lamprey, an eel-like fish, regrows the neurons that comprise the long nerve "highways" that link the brain to the spinal cord.

First molecular test developed to detect eosinophilic esophagitis

Researchers at Cincinnati Children's Hospital Medical Center have developed the first molecular test to diagnose eosinophilic esophagitis, a chronic upper gastrointestinal disorder. The incidence of EoE has skyrocketed since it was first characterized two decades ago.

Inhibition of parvalbumin-expressing prefrontal interneurons triggers fear behaviours

Using an approach combining in vivo recordings and optogenetic manipulations in mice, the researchers succeeded in showing that the inhibition of parvalbumin-expressing prefrontal interneurons triggers a chain reaction resulting in fear behaviour. Conversely, activation of these parvalbumin interneurons significantly reduces fear responses in rodents.
