Dipyrone may reduce brain damage after stroke

An older nonsteroidal anti-inflammatory drug (NSAID) called dipyrone may offer a new approach to reducing injury to brain tissue after a stroke, according to a study in the October issue of Neurosurgery, official journal of the Congress of Neurological Surgeons.

Budding yeast helps make useful predictions about the biology of individuals

It now only costs a few thousand Euros to sequence the genome of an individual human. However, for most of us, knowing our genome sequence would not be useful. Each human has more than 20 000 genes, and in each of us several thousand of these genes carry mutations.

Non-therapeutic antibiotic usage in food animals creates resistance genes, promotes antibiotic resistance

In a review study, researchers from Tufts University School of Medicine zero in on the controversial, non-therapeutic use of antibiotics in food animals and fish farming as a cause of antibiotic resistance.

Leading alcohol researchers to discuss latest genetic findings at Loyola meeting

Leading alcohol researchers from the United States and Canada will discuss their latest findings at an all-day meeting Nov. 18 at Loyola University Chicago Stritch School of Medicine.

Mirna reports new preclinical data of miRNA-based therapeutic candidate for hepatocellular carcinoma

Mirna Therapeutics, Inc., a biotechnology company pioneering microRNA replacement therapy for cancer, announced the presentation today of new preclinical data on the development of a miRNA-based therapeutic candidate for primary liver cancer at the AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics in San Francisco, CA.

Coronary calcium scoring can determine risk of cardiac events

If your doctor says you have a negative stress test, or that your cholesterol or blood pressure are normal, how assured can you be that you're not likely to have a heart attack in the next seven to 10 years?

Insulin sensitivity in the ovaries and the pituitary linked to infertility

Infertility is common among obese women, but the reasons remain poorly understood and few treatments exist. Now a team of Johns Hopkins Children's Center scientists, conducting experiments in mice, has uncovered what they consider surprising evidence that insulin resistance, long considered a prime suspect, has little to do with infertility in women with type-2 diabetes, polycystic ovary syndrome and metabolic syndrome, all obesity-related conditions.

Human pluripotent stem cells rely heavily on glycolysis to drive their metabolic activities

Human pluripotent stem cells, which can develop into any cell type in the body, rely heavily on glycolysis, or sugar fermentation, to drive their metabolic activities.

Just 20 seconds to know whether a stranger is trustworthy, kind or compassionate

There's definitely something to be said for first impressions. New research from the University of California, Berkeley, suggests it can take just 20 seconds to detect whether a stranger is genetically inclined to being trustworthy, kind or compassionate.

Atherosclerotic plaques spread downstream in coronary arteries

In human coronary arteries, atherosclerotic plaques tend to spread downstream because of the changes in blood flow patterns the plaque causes, researchers have found.

CDCs can increase healthy heart muscle cells in patients with ischemic heart disease

Healthy, new heart cells have been generated by animals with chronic ischemic heart disease after receiving stem cells derived from cardiac biopsies or "cardiospheres," according to research conducted at the University at Buffalo School of Medicine and Biomedical Sciences.

Study detects contrasting patterns of malaria drug resistance in humans, mosquitoes

A study conducted by researchers at the Johns Hopkins Malaria Research Institute and their Zambian colleagues detected contrasting patterns of drug resistance in malaria-causing parasites taken from both humans and mosquitoes in rural Zambia.

Sex during adolescence can have negative effects on body and mood well into adulthood

A new study suggests that sex during adolescence can have lasting negative effects on the body and mood well into adulthood, most likely because the activity occurs when the nervous system is still developing.

Molecular level insights into connection between cancer and diabetes

Developing type 2 diabetes is a lengthy process. An early sign that it has begun is high levels of insulin in the blood. As long as the insulin-producing beta cells are able to compensate for the increased demand, for example when the individual is overweight, the blood sugar levels remain normal. It is not until the capacity for insulin secretion falls below the level needed that type 2 diabetes becomes a fact. The latter stage generally goes quickly, as the stressed beta cells work themselves to death.

Researchers examine how brain recognizes color

How the brain perceives color is one of its more impressive tricks. It is able to keep a stable perception of an object's color as lighting conditions change.

Alcohol can readily decrease function of women's serotonin system

After only four years of problem drinking, a significant decrease in the function of the serotonin system in women's brains can be seen. This is the system that regulates such functions as impulse control and mood. It takes 12 years before a corresponding decrease is seen in men.

Researchers discover human genes that might contribute to ALS

Amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease, is a universally fatal neurodegenerative disease. Mutations in two related proteins, TDP-43 and FUS, cause some forms of ALS. Specifically, these two proteins are RNA-binding proteins that connect to RNA to regulate the translation of proteins and other cellular functions such as RNA splicing and editing. In a new study, researchers at the Perelman School of Medicine at the University of Pennsylvania discovered additional human genes with properties similar to TDP-43 and FUS that might also contribute to ALS.

AHA honors Gladstone senior investigator with Distinguished Scientist Award

The American Heart Association will today present Gladstone Institutes Senior Investigator and President Emeritus Robert Mahley, MD, PhD, with the 2011 AHA Distinguished Scientist Award, bestowing yet another honor on one of Gladstone's founding cardiovascular scientists.

Scarring prevents precipitous decline in heart function after cardiac injury

After a heart attack, the portions of the heart damaged by a lack of oxygen become scar tissue. Researchers have long sought ways to avoid this scarring, which can harden the walls of the heart, lessen its ability to pump blood throughout the body and eventually lead to heart failure. But new research from the University of North Carolina at Chapel Hill School of Medicine shows that interrupting this process can weaken heart function even further.

Blood-based gene expression test more effective in ruling out obstructive CAD

A blood-based gene expression test was found to be more effective for ruling out obstructive coronary artery disease in stable symptomatic patients than myocardial perfusion imaging (MPI), a common test that uses a radioactive agent to evaluate the blood flow and function of the heart.
