Heart-protective protein finally found

It is a cellular component so scarce, some scientists even doubted its existence, and many others gave up searching for its molecular structure. Now a team led by researchers at Johns Hopkins has defined the protein structural composition of mitoKATP, a potassium channel in the mitochondria of the heart and other organs that is known to protect against tissue damage due to a heart attack or stroke.

Smoking, hepatitis and liver transplantation: An interview with Dr Peter Ghali

We are very interested in hepatitis C as it is the most common indication for liver transplant in the Western world. The difficulty is that recurrence happens in the majority of patients within the first 2 to 7 years after transplant, and occasionally sooner.

Mu-opioid receptors put brakes on appetite

Activation of mu-opioid receptors in the nerves of the portal vein walls triggers a gut–brain neural circuit that leads to feelings of satiety, researchers report in Cell.

Johnson & Johnson second quarter sales decrease 0.7% to $16.5B

Johnson & Johnson today announced sales of $16.5 billion for the second quarter of 2012, a decrease of 0.7% as compared to the second quarter of 2011. Operational results increased 3.5% and the negative impact of currency was 4.2%.

WCMC receives NHLBI grant to study smoking-induced COPD

Researchers at Weill Cornell Medical College were awarded a $6.5 million grant from the National Heart, Lung, and Blood Institute for a five-year investigation into metabolic changes occurring within airway epithelial cells in the lungs of chronic obstructive pulmonary disease (COPD) patients caused by cigarette smoking. In addition, researchers aim to identify which cigarette smokers are at highest risk of developing COPD as well as novel biomarkers to assist in the development of new therapeutic treatments for the disease.

Healthier levels of vitamin C can reduce inflammatory conditions

The recommended dietary allowance, or RDA, of vitamin C is less than half what it should be, scientists argue in a recent report, because medical experts insist on evaluating this natural, but critical nutrient in the same way they do pharmaceutical drugs and reach faulty conclusions as a result.

High blood pressure associated with reduced mortality in extremely frail, elderly adults

A new study suggests that higher blood pressure is associated with lower mortality in extremely frail, elderly adults.

Researchers begin to uncover important clues about SCAD

Spontaneous coronary artery dissection (SCAD), a tear of the layers of the artery wall that can block normal blood flow into and around the heart, is a relatively rare and poorly understood condition. It often strikes young, otherwise healthy people -- mostly women -- and can lead to significant heart damage, even sudden death.

New Alzheimer's model derived from skin cells of patients may prove to be more accurate

Researchers at the Alzheimer's Association International Conference 2012 (AAIC 2012) today reported the creation of a new model of Alzheimer's derived from the skin cells of people with the disease that were reprogramed into Alzheimer's brain cells.

Helper T cells may be frontline warriors when battling hepatitis A infection

Helper cells traditionally thought to only assist killer white blood cells may be the frontline warriors when battling hepatitis A infection. These are the findings from a Nationwide Children's Hospital study appearing in a recent issue of the Journal of Experimental Medicine.

Tips to help minimize risks associated with acid reflux disease

While the overall death rates from several cancers such as breast and lung have gone down, there has been a meteoric rise in cases of esophageal cancer. Studies have shown that from 1975 to 2001, the incidence of esophageal adenocarcinoma rose approximately sixfold in the United States (from four to 23 cases per million), a relative increase greater than that for melanoma, breast, or prostate cancer.

Why is the incidence of gout increasing?

Gout has been described by the Daily Mail as something, “usually associated with port-swilling, over-fed elderly men of the 19th century”. (1) Recent research carried out at the Boston University School of Medicine, however, has found that the incidence of gout in the US is on the rise. (2) Thus, the condition is clearly not something that only affects this stereotype.

Scientists discover new way to convert cord blood cells into iNC

For more than 20 years, doctors have been using cells from blood that remains in the placenta and umbilical cord after childbirth to treat a variety of illnesses, from cancer and immune disorders to blood and metabolic diseases.

VHVI now offers new minimally invasive, catheter-based approach to dissolve pulmonary embolism

The Vanderbilt Heart and Vascular Institute (VHVI) now offers a minimally invasive, catheter-based approach to dissolving pulmonary embolism, a potentially life-threatening blood clot that form elsewhere in the body and travels into the lungs.

BRAF L597 mutation in melanoma patients responds to MEK inhibitor drugs

An uncommon mutation of the BRAF gene in melanoma patients has been found to respond to MEK inhibitor drugs, providing a rationale for routine screening and therapy in melanoma patients who harbor the BRAF L597 mutation.

InvivoSciences, WUSTL to construct artificial tissue models for heart failure

The National Institutes of Health has awarded more than $2 million to a team of scientists from Washington University in St. Louis and InvivoSciences, a biotechnology startup with WUSTL roots, to construct artificial tissue models that will allow the rapid testing of new drugs for heart failure.

Targeting CDK1 pathway may be efficacious for acute myeloid leukemias with FLT3 mutation

Acute myeloid leukemia, a common leukemia in adults, is characterized by aberrant proliferation of cancerous bone marrow cells. Activating mutations in a protein receptor known as FLT3 receptor are among the most prevalent mutations observed in acute myeloid leukemias. FLT3 mutants are thought to activate several signaling pathways that contribute to cancer development.
