Neurons that trigger our sense of thirst—and neurons that turn it off—have been identified by Columbia University Medical Center neuroscientists. The paper was published today in the online edition of Nature.
A team of oncology and genetic researchers from Georgetown Lombardi and electrical and computer engineers and bioinformatics specialists from Virginia Tech collaborated in an effort designed to study the living cell as an information processing system.
Scorpions can teach us a lot about the benefits of prolonging nerve impulses, and we might now be better students. The results of a new study could pave the way for easier identification of drugs that function similarly to scorpion venom, but with happier results for the recipient.
Leaks are not just problems for plumbers and politicians; researchers reveal how leaky transmembrane channels could cause disruptions in normal heart function. The study suggests that ion leaks in mutant sodium channels might contribute to an unusual set of cardiac arrhythmias.
Researchers have identified a population of “progenitor” cells in the skin that are solely responsible for the generation and maintenance of touch-sensing Merkel cells.
) Using a simple camera and water tank, investigators from Dartmouth-Hitchcock’s Norris Cotton Cancer Center demonstrated that induced Cherenkov light can be imaged and used to confirm that the complex spatial dose distribution imparted in dynamic treatment plans is being delivered correctly.
Researchers have shown that neonatal mouse hearts have varying regenerative capacities depending upon the severity of injury. Approaches to extend this regenerative capacity in a mammalian model, from the neonatal period to the juvenile or adult period, could help identify new treatment options for humans.
The Monell Center has received a $1.5M NIH grant to further develop clinical methodology that can predict the path of air flow through a person’s nasal passages. The methodology may someday help physicians predict success taes for surgery to reverse nasal obstruction and associated loss of smell (anosmia).
1.4 million Americans suffer from uncomfortable abdominal cramping and diarrhea that come with inflammatory bowel disease (IBD). The condition is associated with an imbalance among the thousands of species of “good” bacteria that inhabit the gut. A University of Utah study published on Jan. 22 in Cell Host and Microbe demonstrates that a component of the immune system, MyD88, coordinates a host immune response that promotes a healthy colony of good bacteria, and digestive health.
NYU educators and clinicians have developed an educational and clinical innovation transitioning the traditional head, ears, eyes, nose, and throat (HEENT) examination to the addition of the teeth, gums, mucosa, tongue, and palate examination (HEENOT) for assessment, diagnosis, and treatment of oral–systemic health problems.
Researchers report on the use of denoising autoencoders (DAs) to effectively extract key biological principles from gene expression data and summarize them into constructed features with convenient properties.
By analyzing such parameters as the force applied by key presses and the time interval between them, a new self-powered non-mechanical intelligent keyboard could provide a stronger layer of security for computer users.
Case Western Reserve scientists have taken a leap toward identifying root causes of psoriasis. Of the roughly 50,000 proteins in the human body, researchers have zeroed in on four likely contributors to this inflammatory skin condition. The findings were published Molecular & Cellular Proteomics.
Existing cancer therapies are geared toward massacring tumor cells, but Johns Hopkins researchers propose a different strategy: subtly hardening cancer cells to prevent them from invading new areas of the body. They devised a way of screening compounds for the desired effect and have identified a compound that shows promise in fighting pancreatic cancer.
Researchers at The Saban Research Institute of Children’s Hospital Los Angeles now reveal an unexpected role for ghrelin in early brain development and show its long-term impact on appetite regulation. Their study will be published online January 20 by The Journal of Clinical Investigation.
An animal study led by Johns Hopkins investigators has uncovered what controls the ability of healthy hearts to speed up in response to circumstances ranging from fear to a jog around the block.
Elderly LGBT adults will get free screenings for blood pressure, oral health, mental health, HIV, and Hepatitis C at a health fair to kick off the e-linc program. Wednesday, January 21, 1:00pm to 4:00pm at SAGE Center, 305 Seventh Ave, 15th floor, NY, NY.
Some cone snails add insulin to the venom cocktail they use to catch fish, University of Utah biologists have discovered. Adding the hormone to the mix of venom toxins may have enabled predatory cone snails to disable entire schools of swimming fish with hypoglycemic shock. The snail insulin could prove useful as a tool to probe the systems the human body uses to control blood sugar and energy metabolism.
Researchers at the University of Michigan Comprehensive Cancer Center analyzed the global landscape of a portion of the genome that has not been previously well-explored. This analysis opens the door to discovery of thousands of potential new cancer biomarkers.
A group of white blood cells known as B cells, which play a key role in the human immune response, need a protein-targeting signal called M6P in order to proliferate, differentiate, and present immune cell–activating antigens.
