Nitroglycerin can boost body's natural immune response to cancer

Researchers at Queen's University have identified a new mechanism that could potentially explain why the body's immune system sometimes fails to eliminate cancer. The new findings shed light on the possible cause of immune resistance in cancer cells, and indicate that nitroglycerin, a relatively safe and low-cost drug used for more than a century to treat angina, may be effective for managing certain cancers.

Antioxidant can delay onset of all indicators of Alzheimer's

When you cut an apple and leave it out, it turns brown. Squeeze the apple with lemon juice, an antioxidant, and the process slows down. Simply put, that same "browning" process-known as oxidative stress-happens in the brain as Alzheimer's disease sets in. The underlying cause is believed to be improper processing of a protein associated with the creation of free radicals that cause oxidative stress.

Scientists identify importance of novel protein-regulating mechanism

For years, science has generally considered the phosphorylation of proteins -- the insertion of a phosphorous group into a protein that turns it on or off -- as perhaps the factor regulating a range of cellular processes from cell metabolism to programmed cell death. Now, scientists from the Florida campus of The Scripps Research Institute have identified the importance of a novel protein-regulating mechanism -- called sulfenylation -- that is similar to phosphorylation and may, in fact, open up opportunities to develop new types of drugs for diseases such as cancer.

Washington Hospital opens Central Utility Plant

Washington Hospital, the local provider of healthcare for the Tri-City area and one of the region's best medical facilities, today opened a state of the art Central Utility Plant that will provide energy for the campus' expansion and modernization for decades to come.

Researchers discover molecular marker for immediate precursors of blood stem cells

A research team led by Nancy Speck, PhD, professor of Cell and Developmental Biology at the Perelman School of Medicine at the University of Pennsylvania, has discovered a molecular marker for the immediate precursors of hematopoietic (blood) stem cells (HSCs) in the developing embryo, which provides much-needed insights for making these cells from engineered precursors.

FDA advisory panel OKs anemia drug peginesatide

Once approved by the FDA, the once-monthly injection could capture a share of the $3 billion U.S. market for anemia drugs used for kidney dialysis patients, currently dominated by Amgen Inc's blockbuster Epogen. Affymax, which developed the drug with partner Takeda Pharmaceutical Co Ltd, is also expected to price its product below Epogen.

New gene editing technique can heal sickle cell patients with their own cells

Researchers at the Salk Institute for Biological Studies have developed a way to use patients' own cells to potentially cure sickle cell disease and many other disorders caused by mutations in a gene that helps produce blood hemoglobin.

First study to identify molecular mechanism that links inflammation to cancer epigenetics

Johns Hopkins Kimmel Cancer Center scientists report that sharp rises in levels of reactive oxygen molecules, and the inflammation that results, trigger biochemical changes that silence genes in a pattern often seen in cancer cells. The researchers confirmed this gene-silencing effect in mice that develop inflammation-induced colon cancer.

Pycnogenol enhances mental performance

Keeping your brain in shape-no sweat. Health-conscious consumers may not realize that supplementing a healthy diet is just as important to maintaining mental performance as it is to maintaining six-pack abs.

Biosensors can detect oxidant production in living organism

Arterial calcification and coronary heart disease, neurodegenerative diseases such as Parkinson's and Alzheimer's, cancer and even the aging process itself are suspected to be partially caused or accelerated by oxidative stress. Oxidative stress arises in tissues when there is an excess of what are called reactive oxygen species.

Growth hormone PDGF-BB and blood protein EPO implicated in development of cancer

Researchers at the Swedish medical university Karolinska Institutet have demonstrated that a growth hormone, PDGF-BB, and the blood protein EPO are involved in the development of cancer tumours and that they combine to help the tumours proliferate in the body.

Treatments for lymphoma with no side effects

Larry Conrad went in for his annual physical on his 50th birthday. During his exam, his doctor found swollen lymph nodes in his armpits and groin. Conrad had a cough and said he'd lost weight because he 'felt full all the time'. His doctor ordered a series of tests, and Conrad was diagnosed with Non-Hodgkin's lymphoma, the most common type.

Novel interventions promote CPAP use among people with OSA

People with obstructive sleep apnea are more likely to stick to prescribed treatment when a partner or parent is involved with their treatment, according to a team of sleep researchers.

Researchers discover why men more likely than women to develop squamous cell skin cancer

Men are three times more likely than women to develop a common form of skin cancer but medical science doesn't know why. A new study may provide part of the answer.

Study presents high-resolution genome-wide p53-binding map for normal human cells

Scientists investigating the interactions, or binding patterns, of a major tumor-suppressor protein known as p53 with the entire genome in normal human cells have turned up key differences from those observed in cancer cells. The distinct binding patterns reflect differences in the chromatin (the way DNA is packed with proteins), which may be important for understanding the function of the tumor suppressor protein in cancer cells.

Researchers reveal ambivalent role of CXCL12/CXCR4 molecule in myocardial infarction

The chemokine CXCL12 acts as a chemical signal which mobilizes hematopoietic and other types of stem cells to leave the bone marrow and enter the circulation. Secretion of CXCL12 also guides these cells to sites at which the perfusion of tissue is sub-optimal due to localized obstruction of blood flow. These capabilities have made CXCL12 and its cognate receptor CXCR4 interesting candidates for therapies aimed at mitigating the effects of damage to the heart caused by myocardial infarction.

Inflammasome may lead to more damage following heart attack

Virginia Commonwealth University researchers have found that an inflammatory mechanism known as inflammasome may lead to more damage in the heart following injury such as a heart attack, pointing researchers toward developing more targeted strategies to block the inflammatory mechanisms involved.

Coronary CTA reveals different heart attack risk scenarios for men and women

Findings on coronary CT angiography (CTA), a noninvasive test to assess the coronary arteries for blockages, show different risk scenarios for men and women, according to a study presented today at the Radiological Society of North America.

Study finds no difference in running economy of senior runners

Runners over the age of 60 are the fastest-growing group in the sport. A new study from the University of New Hampshire suggests that their running can remain fast as they age, too.

Anemia, high blood pressure linked to risk of silent strokes in children with SCD

A team of researchers from the Johns Hopkins Children's Center, Vanderbilt University and elsewhere have demonstrated that high blood pressure and anemia together put children with sickle cell disease (SCD) at serious danger for symptomless or so-called "silent" strokes, although either condition alone also signaled high risk.
