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.

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.

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.

Scientists solve mystery behind why people with defective hemoglobin do not contract malaria

Why do people with a hereditary mutation of the red blood pigment hemoglobin not contract severe malaria? Scientists in the group headed by Prof. Michael Lanzer of the Department of Infectious Diseases at Heidelberg University Hospital have now solved this mystery.

Hemoglobin levels, blood pressure and male gender linked to higher risk of silent strokes in SCA children

Factors such as low hemoglobin levels, increased systolic blood pressure, and male gender are linked to a higher risk of silent cerebral infarcts (SCIs), or silent strokes, in children with sickle cell anemia (SCA), according to results from a large, first-of-its-kind study published online today in Blood, the Journal of the American Society of Hematology (ASH).

Stem cell therapy for heart failure: two studies two successes

The Center for Disease Control and Prevention says that heart failure affects nearly 6 million Americans leading to considerable risk of death, diminished quality of like and recurrent hospitalizations. Heart failure occurs when the heart can no longer pump enough blood to the rest of the body. The most common cause of heart failure is coronary artery disease, which narrows the small blood vessels that supply blood and oxygen to the heart.
