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.

Medizone receives Canadian patent for AsepticSure hospital disinfection product

Medizone International, Inc. reports that the Canadian Patent Office has granted Canadian Patent No 2735739 for processes and systems relating to the platform technology of its revolutionary AsepticSure hospital disinfection product.

Herbicide atrazine linked to reproductive dysfunction

An international team of researchers has reviewed the evidence linking exposure to atrazine - an herbicide widely used in the U.S. and more than 60 other nations - to reproductive problems in animals. The team found consistent patterns of reproductive dysfunction in amphibians, fish, reptiles and mammals exposed to the chemical.

Post traumatic stress disorder and concussion syndrome treatable three years after injury: Study

Research led by Dr. Paul Harch, Associate Clinical Professor of Medicine at LSU Health Sciences Center New Orleans, has found that treatment with hyperbaric oxygen nearly three years after injury significantly improved function and quality of life for veterans with traumatic brain injury and post-traumatic stress disorder.

Scientists identify cellular protein that plays central role in formation of new blood vessels

Scientists at the University of North Carolina at Chapel Hill School of Medicine have identified a cellular protein that plays a central role in the formation of new blood vessels.

First time mothers may put themselves and baby at risk by choosing home-birth: Report

A new report suggests that first time mothers who opt for a home birth are almost three times more likely to have a baby who dies or suffers brain damage. It also found that traditional maternity units in hospital are the safest place for women to have their first child.

Cancer medicine component could prevent heart attacks

A substance in medicines for cancer and epilepsy could also prevent heart attacks, according to researchers at the Sahlgrenska Academy at the University of Gothenburg, Sweden, who have been using it to stimulate the body's own defence system against blood clots.

TLRs contribute to brain damage following hypoxia in newborns

Two out of every thousand babies are at risk of brain damage in connection with birth. Researchers at the Sahlgrenska Academy at the University of Gothenburg, Sweden, have identified mechanisms behind these injuries, which could lead to better treatment and a richer life for the infants affected.

Tips for parents to safeguard their children

They say parents know best, but what if you are a new parent who doesn't know it all quite yet? "Unfortunately, babies do not come with a safety manual. Sometimes parents do things that are well-intentioned but can be unsafe for their child," said Mary Evelyn O'Neil, M.D., pediatrician, Wake Forest Baptist Medical Center.

CWRU receives NHLBI grant to study sleep apnea as possible cause of AF

Case Western Reserve University School of Medicine has received a $3.8 million grant from the National Heart, Lung, and Blood Institute (NHLBI) to study sleep apnea as a possible cause of atrial fibrillation (AF), the most commonly diagnosed type of arrhythmia, or irregular heart rhythm.

HRR1 after 6MW test is a strong predictor of clinical worsening in IPAH patients

Heart rate recovery at one minute after a six-minute walking distance (6MWD) test is highly predictive of clinical worsening and time to clinical worsening in patients with idiopathic pulmonary arterial hypertension (IPAH), according to a new study.
