Scientists are learning more about how protein gets in the urine when the kidneys begin to fail and how a new drug blocks it.

Long-nosed Cape rock elephant-shrews are fond of sticky treats, according to Dr. Petra Wester from the University of Stellenbosch in South Africa. Her investigations show for the first time that the elephant-shrew, Elephantulus edwardii, licks the nectar of the flowers and pollinates the Pagoda lily. Her results are published in Springer's journal, Naturwissenschaften – The Science of Nature.
CINCINNATI—University of Cincinnati (UC) researchers have discovered a new protein that could be cardioprotective during heart attack, potentially leading to more targeted treatments for patients at risk.
These findings are being presented at the American Heart Association's (AHA) Scientific Sessions in Chicago Nov. 16.
Dr. Joseph Glavy at Stevens Institute of Technology studies the smallest and most basic elements of life. The Assistant Professor of Chemical Biology runs the Glavy Lab, where advanced student scientists study the nuclear pore complexes (NPCs) in cells, observing the minutest mechanisms of life as they unfold during mitosis. The Glavy Lab's formal purpose is to study the NPC at the molecular level in the pursuit of the unknown or unexpected in the well-studied but not always well-understood nuclei of living cells.
CINCINNATI—Researchers at the University of Cincinnati (UC) have found that fat around the outside of arteries may lead to the development of cardiovascular disease and could be linked to its onset in individuals with diabetes.
David Manka, PhD, a researcher in the division of cardiovascular diseases, and his team found that this fat—known as perivascular adipose tissue—could possibly lead to the formation of fatty buildup inside of arteries and could cause existing buildup to break loose, leading to stroke or heart attack.
OAK BROOK, Ill. – The risk of radiation-induced breast cancer from mammography screening is slight in comparison to the benefit of expected lives saved, according to a new study appearing online and in the January issue of the journal Radiology.
Umbilical cord stem cells may be useful in the treatment of rheumatoid arthritis (RA). Animal and in vitro experiments, described in BioMed Central's open access journal Arthritis Research and Therapy, have shown that mesenchymal stem cells (MSCs) taken from umbilical cord blood can suppress inflammation and attenuate collagen-induced arthritis.
People who use herbal and dietary supplements along with warfarin, an anti-clotting medication, are often not aware that they might be compromising the drug's safety and efficacy, according to new research.
Researchers surveyed 100 warfarin-treated patients for 1) the frequency of herbal and dietary supplement use among patients treated with warfarin (also known as Coumadin); 2) if a communication gap about the simultaneous use of warfarin and herbal and dietary supplements existed between physicians and patients; and 3) barriers to communication.
They found that:
To mark The World Day of Remembrance for Road Traffic Victims, which takes place on Sunday November 21st, PLoS Medicine publishes two research articles on Road Traffic Crashes.
The World Day of Remembrance for Road Traffic Victims takes place on the third Sunday of November every year as the appropriate acknowledgment of victims of road traffic crashes and their families. It was started by RoadPeace in 1993 and was adopted by the United Nations General Assembly in 2005.
Prescribed medicines are responsible for over 3% of road traffic crashes in France
Injecting a platelet inhibitor directly into the heart through a coronary artery (intracoronary) may restore blood flow more effectively than conventional administration through a vein (intravenous) after a severe heart attack, according to new research.
ANN ARBOR, Mich---University of Michigan researchers have determined that most types of melanoma cells can form malignant tumors, providing new evidence that the deadliest form of skin cancer does not conform to the increasingly popular cancer stem cell model.
In addition, the researchers found that melanoma tumor cells can change their appearance by switching various genes on and off, making the malignant cells a stealthy, shape-shifting target for researchers seeking new treatments, according to a team led by Sean Morrison, director of the U-M Center for Stem Cell Biology.
Like us, plants rely on an immune system to fight off disease. Proteins that scout out malicious bacterial invaders in the cell and communicate their presence to the nucleus are important weapons in the plant's disease resistance strategy. Researchers at the University of Missouri recently "tapped" into two proteins' communications with the nucleus and discovered a previously unknown level of cross talk.
Surgical items, such as sponges and small instruments, left in the bodies of children who undergo surgery are quite uncommon and rarely fatal but decidedly dangerous and expensive mistakes, according to a Johns Hopkins Children's Center study to be published in the November issue of JAMA-Archives of Surgery.
Such errors added eight days, on average, to a young patient's hospital stay and nearly $36,000 in extra hospital charges, both stemming from complications and the need for follow-up surgery to retrieve the forgotten objects.
STANFORD, Calif. — A preservative-free alternative to standard nasal sprays — which routinely use preservatives that can cause unwanted side effects, such as allergies or damage to the mucosal lining of the nose — was found to be both safe and well-tolerated, in a short-term study from the Stanford University School of Medicine.
The alternative acidified solution also maintained sterility in the applicator bottle without the use of the chemical preservatives, according to the study, which will be published Nov. 15 in the Archives of Otolaryngology-Head & Neck Surgery.
