Study suggests new treatment strategy for heart attacks and strokes

A heart attack doesn't just damage heart muscle tissue by cutting off its blood supply, it also sets off an inflammatory cascade that worsens underlying atherosclerosis, actively increasing the risk for a future heart attack. These findings from a study receiving advance online publication in Nature suggest an important new therapeutic strategy for preventing heart attacks and strokes, both of which are caused when atherosclerotic plaques rupture and block important blood vessels.

New compound could treat certain types of genetic disorders in muscles

Scientists at UCLA have identified a new compound that could treat certain types of genetic disorders in muscles. It is a big first step in what they hope will lead to human clinical trials for Duchenne muscular dystrophy.

Scientists now have clues to how GATA4 gene mutation leads to septal defects in babies with CHD

Scientists now have clues to how a gene mutation discovered in families affected with congenital heart disease leads to underdevelopment of the walls that separate the heart into four chambers.

Prenatal exposure to BPA appears to program uterine estrogen responsiveness in adulthood

Prenatal exposure to bisphenol A, or BPA, a chemical found in many common plastic household items, can cause numerous genes in the uterus to respond differently to estrogen in adulthood, according to a study using a mouse model. The results will be presented Tuesday at The Endocrine Society's 94th Annual Meeting in Houston.

GMCSF linked with rapid cognitive recovery in patients with cancer

Growth factors shown to cure Alzheimer's disease in a mouse model and administered to cancer patients as part of their treatment regimen were linked to significant improvements in the patients' cognitive function following stem cell transplantation, a preliminary clinical study reports.

WCMC researchers devise innovative boxer-like strategy to fight multiple myeloma

Weill Cornell Medical College researchers have devised an innovative boxer-like strategy, based on the serial use of two anti-cancer drugs, to deliver a one-two punch to first weaken the defenses of multiple myeloma and then deliver the final knock-out punch to win the fight.

Researchers develop new mouse model to study supertasting

Supertasting describes the ability to strongly detect food flavors such as bitter and sweet, and it can affect a person's food preferences. For example, supertasters are often averse to green vegetables because their bitter taste is amplified. Supertasters may also prefer foods lower in sugar and fat. Approximately one out of four people is a supertaster, and a supertaster's avoidance of sweet and fatty foods may have protective cardiovascular effects.

NF-κB inhibitors can mitigate cellular damage and prevent aging-related degenerative changes

Age-associated degeneration is caused, at least in part, by accumulated cellular damage, including DNA damage, but how these types of damage drive aging remains unclear. Dr. Paul Robbins and colleagues at the University of Pittsburgh sought to address this question using a mouse model of DNA repair deficiency.

Breast milk protects against oral transmission of HIV

More than 15 percent of new HIV infections occur in children. Without treatment, only 65 percent of HIV-infected children will live until their first birthday, and fewer than half will make it to the age of two. Although breastfeeding is attributed to a significant number of these infections, most breastfed infants are not infected with HIV, despite prolonged and repeated exposure.

Western-style diets may increase risk of inflammatory bowel disease

Certain saturated fats that are common in the modern Western diet can initiate a chain of events leading to complex immune disorders such as inflammatory bowel diseases (IBD) in people with a genetic predisposition, according to a study to be published early online in the journal Nature.

Alpha-myosin triggers development of autoimmunity after heart attack

After people with type 1 diabetes have a heart attack, their long-term chance of suffering even more heart damage skyrockets. But the reason has long puzzled scientists. Now researchers at Joslin Diabetes Center have identified the misstep that sparks this runaway chronic damage and a promising way to block it.

Gut microbes regulate brain levels of serotonin

UCC scientists have shown that brain levels of serotonin, the 'happy hormone' are regulated by the amount of bacteria in the gut during early life. Their research is being published today in the leading international psychiatry journal, Molecular Psychiatry.

Discovery answers why mother's immune system does not reject developing fetus as foreign tissue

Researchers at NYU School of Medicine have made an important discovery that partially answers the long-standing question of why a mother's immune system does not reject a developing fetus as foreign tissue.

Study packs powerful one-two punch in the fight against heart failure

A new study in the journal Circulation packs a powerful one-two punch in the fight against heart failure. The leading blow: Identification of a unique alliance of proteins that plays a major role in the development of the disease. The second but equally powerful hit: Drugs that interfere with this axis already exist.

Tp53 genetic mutation may play an important role in prostate cancer

A team of UC Davis investigators has found that a genetic mutation may play an important role in the development of prostate cancer. The mutation of the so-called p53 (or Tp53) gene was previously implicated in late disease progression, but until now has never been shown to act as an initiating factor. The findings may open new avenues for diagnosing and treating the disease.
