How heart is formed in the embryo helps explain congenital heart disease

Children's Hospital of Pittsburgh Cardiologist Bradley B. Keller, MD, and his research team are discovering details in the lab that explain how the heart is formed in the embryo. This knowledge improves the chances of doctors identifying fetuses who can benefit from intervention to treat congenital defects.

Metabolic side effects of antipsychotics are known, but rarely monitored

Psychiatrists are doing a “modest” job of monitoring for weight gain, diabetes and other metabolic problems that may result from use of the newer antipsychotics for schizophrenia, researchers say.

Sildenafil prevents anti-cancer drug induced heart damage

Virginia Commonwealth University researchers have found that the popular impotence drug Viagra prevents damage to the heart from a potent chemotherapeutic agent frequently used in the treatment of breast cancer, leukemia and sarcomas.

Practice wait training while weight training

In today’s busy world, cutting corners to fit everything in is a daily truth. However, the one place you should not skimp is in your weight-training schedule.

Alteration of steroid receptor genes creates fat burning muscle

The Salk Institute scientist who earlier discovered that enhancing the function of a single protein produced a mouse with an innate resistance to weight gain and the ability to run a mile without stopping has found new evidence that this protein and a related protein play central roles in the body's complex journey to obesity and offer a new and specific metabolic approach to the treatment of obesity related disease such as Syndrome X (insulin resistance, hyperlipidemia and atherosclerosis).

Zinc appears to help boys learn

Seventh graders given 20 mg zinc, five days per week, for 10 to 12 weeks showed improvement in mental performance, responding more quickly and accurately on memory tasks and with more sustained attention, than classmates who received no additional zinc.

Potential therapeutic role for the ataxin-3 protein for Machado-Joseph disease

The repetition of three little "letters" within the gene that codes for the ataxin-3 protein is both the cause of and perhaps a solution to Machado-Joseph disease and an entire family of similar genetic disorders, according to researchers at the University of Pennsylvania.

Cannabis-based medicines given in a highly-controlled clinical environment unexpectedly lead to strong psychotic effects

Volunteers taking cannabis-based therapeutic drugs as part of a controlled trial, which had been approved by an ethics board as safe for the subjects, experienced psychotic effects just as strong as if they had smoked cannabis. These findings, highly unexpected in such a controlled environment, are published today in the peer-reviewed, Open Access journal BMC Psychiatry.

Movie techniques, MRI/CT data combine with computer modeling of knee/patella to aid surgery

Take the kinds of movie techniques that allow animation with true-life action, throw in an anatomically-based muscle, ligament, tendon, bone and soft-tissue geometries dataset, and add individual patient MRI or CT scan data.

Being a couch potatoe may run in family

So, you don’t like to exercise? Maybe you could blame it on your great-great-grandparents. Similarly, if you’re a practiced and proud couch potato who suddenly woke up to the fact that you’re a “natural” athlete, the credit could also belong to your genes.

Estrogen, SERMS reduce asthma impact by halting constriction

For years, anecdotal evidence suggested that ovulating or pregnant women or post-menopausal women taking estrogen supplements, experienced fewer asthma attacks and less severe asthma symptoms, strongly suggesting that perhaps estrogen affects airway smooth muscle function by preventing the hyperresponsiveness characteristic of asthma and other chronic lung diseases.

Alcoholism reduces male heart muscle’s ability to synthesize protein

The fact that men and women react differently to alcohol consumption and addiction, health and behavior risks, disease and death is well known and accepted. Women get drunker faster on less alcohol than men, but fewer women drink either occasionally or heavily, and men are more likely to become dependent on alcohol.

Pediatric burn victims’ recovery, diabetes aided by Fenofibrate

One of the immediate serious results of sudden extreme trauma or stress, including burns and even surgery, is insulin resistance, or diabetes. As a result, healing is delayed, especially in the case of severe burns, and since the body is unable to fully use blood sugar for energy, muscle tissue is broken down as the body scavenges for other possible energy sources.

Moderate aerobic exercise improves cardiovascular and nervous system function in HIV+ subjects

Researchers from Teachers College, Columbia University, and Coler Goldwater Specialty Hospital and Nursing Facility report that moderate aerobic exercise for 10 weeks, three times a week for 45 minutes each session significantly improved function of the nervous system and circulation in those with HIV disease.

Statins, other cholesterol-depleting agents, may disrupt hypertension from developing

Cholesterol-lowering agents, such as the widely-prescribed statin drugs, and cholesterol-blocking agents may prove to be “novel therapeutic agents to modify cellular calcium that contributes to the development of pulmonary hypertension,” according Hemal H. Patel who lead a multidisciplinary team of researchers at the University of California, San Diego (UCSD).

Simvastatin linked to protection against endothelial dysfunction in diabetic rats

Almost two years ago, the diabetes arm of the Heart Protection Study, the largest-ever study using a cholesterol-lowering medication, found that diabetics who took a daily dose of the statin drug simvastatin over five years reduced the risk of a first nonlethal heart attack by 37 percent and risk of a first nonfatal or fatal stroke by 24 percent, regardless of their cholesterol or glucose levels.

Mesoblast moves towards adult stem cell human trials

Exciting Australian adult stem cell company, Mesoblast Limited, today announced that it is set to begin the first human clinical trials using its specialist adult stem cells for orthopaedic and cardiovascular diseases.

Discovery could lead to new drug targets for heart disease

Mice with glowing green hearts have yielded the latest clue in the search for molecules involved in structural heart disease. Vanderbilt University Medical Center investigators found that blocking the activity of a single protein, called CaM kinase, in the mouse heart protects against the damaging effects of a heart attack.

CDC experts sent to Angola to help with Marburg epidemic

In an effort to control the Marburg virus outbreak in Angola, Health officials from the Centers for Disease Control and Prevention in Atlanta will assist the World Health Organization by going to Angola to help with outbreak investigation, infection control and laboratory diagnosis of the disease.
