Obese adolescents not getting enough sleep? A new study shows they could be increasing their risk for developing diabetes, heart disease and stroke. Lack of sleep and obesity have been associated with an increased risk of cardiovascular and metabolic diseases in adults and young children. However, the association is not as clear in adolescents.
A rare skin infection has been traced to raw seafood purchased at fish markets in New York City's three large Chinese neighborhoods, city health officials said Wednesday. There have been 30 reported cases of infection caused by a bacterium called Mycobacterium marinum, according to the city...
Surgery to remove the prostate saves lives compared to "watchful waiting" for some men whose cancers were found because they were causing symptoms, long-term results from a Scandinavian study suggest. However, U.S. men should not assume that immediate treatment is best, doctors warn, because the...
Scientists have modified genes in the blood cells of HIV patients to help them resist the AIDS virus, and say the treatment seems safe and promising. The results give hope that this approach might one day free at least some people from needing medicines to keep HIV under control, a form of cure.
Harvard stem cell scientists have successfully converted skins cells from patients with early onset Alzheimer’s into the types of neurons that are affected by the disease, making it possible for the first time to study this leading form of dementia in living human cells. This may also make it possible to develop therapies more quickly and accurately than before.
How Individual Staphylococcus Cells Adhere to Nanostructures Could Lead to New Ways to Thwart InfectionsMarch 5, 2014 1:22 pm | News | Comments
The bacterium Staphylococcus Aureus (S. aureus) is a common source of infections that occur after surgeries involving prosthetic joints and artificial heart valves. The grape-shaped microorganism adheres to medical equipment, and if it gets inside the body, it can cause a serious and even life-threatening illness called a Staph infection. The recent discovery of drug-resistant strains of S. aureus makes matters even worse.
To fool predators, some butterflies create wing color patterns that make them resemble their unpalatable cousins. Only recently have scientists been unraveling how they do that, and now researchers have identified the gene that does the trick for an Asian swallowtail.
A second baby born with the AIDS virus may have had her infection put into remission and possibly cured by very early treatment — in this instance, four hours after birth. Doctors revealed the case Wednesday at an AIDS conference in Boston. The girl was born in suburban Los Angeles last April, a...
Beer drinkers know that hops are what gives the drink its bitterness and aroma. Recently, scientists reported that the part of hops that isn’t used for making beer contains healthful antioxidants and could be used to battle cavities and gum disease.
Scientists in Freiburg may have discovered a fundamental aggravating factor in autoimmune diseases. If B-lymphocytes lack the protein PTP1B, the cells will become hyperactive for stimulatory signals and can thus promote an autoimmune attack. This study offers an additional explanation to how B-cells regulate an immune response.
In a study that began in a pair of infant siblings with a rare heart defect, Johns Hopkins researchers say they have identified a key molecular switch that regulates heart cell division and normally turns the process off around the time of birth. Their research, they report, could advance efforts to turn the process back on and regenerate heart tissue damaged by heart attacks or disease.
Several fertility clinics across the country are beginning to administer testosterone, either through a patch or a gel on the skin, to increase the number of eggs produced by certain women undergoing in vitro fertilization (IVF). Women are also purchasing the over-the-counter supplement DHEA, which is converted by the body into testosterone, to boost their chances of pregnancy with IVF.
The Muse Cell Analyzer from EMD Millipore uses multiparametric fluorescent detection of individual cells via microcapillary flow technology, enabling highly sensitive and rapid measurement of cell parameters using minimal cell numbers—in a smaller footprint than typical benchtop cell analyzers and standard flow cytometers.
Realtime Stain from Biophoretics is a single step coomassie like pre-electrophoresis protein stain that allows visualizing the separation as it occurs; in real time. The stain irreversibly binds amine groups coloring the proteins deep blue with little to no gel background; providing detection sensitivity as low as 50ng.
Just try sugar-coating this: The World Health Organization says your daily sugar intake should be just 5 percent of your total calories — half of what the agency previously recommended, according to new draft guidelines published Wednesday. After a review of about 9,000 studies, WHO's expert...
