Preclinical study finds how fat tissue fuels cancer growth

Fat progenitor cells may contribute to cancer growth by fortifying the vessels that provide needed blood to tumors, according to preclinical research findings by investigators at The University of Texas Health Science Center at Houston (UTHealth).

Pioneering research paves way for new treatments for pulmonary arterial hypertension

Pioneering research conducted by the University of Sheffield is paving the way for new treatments which could benefit patients suffering from the fatal lung disease pulmonary arterial hypertension (PAH).

Type 2 diabetes screening: an interview with Dr Simon Griffin, MRC Epidemiology Unit at Addenbrooke’s Hospital, Cambridge

Type 2 diabetes is a condition in which the body does not make sufficient insulin or the insulin it makes doesn’t work sufficiently well to maintain a normal level of blood glucose and so the blood glucose rises.

Premature babies from low-income families more likely to develop brain hemorrhages

Babies born prematurely to low-income parents have a disproportionately high risk for developing dangerous brain bleeds that require multiple surgeries and extensive follow-up, according to a small Johns Hopkins Children's Center study.

Clinical study to investigate Cytori's adipose-derived cell therapy in patients with heart failure

Timothy Henry, M.D. of the Minneapolis Heart Institute Foundation treated the first patient in the ATHENA study, injecting the patient's own stem cells into the heart to restore blood flow and help regenerate heart muscle. Henry, the Foundation's Director of Research is co-principal investigator of the ATHENA study sponsored by Cytori Therapeutics.

Novel neuroimaging technique reveals evidence of cocaine-induced cerebral microischemia

Researchers from the Department of Biomedical Engineering at Stony Brook University have developed a high-resolution, 3D optical Doppler imaging tomography technique that captures the effects of cocaine restricting the blood supply in vessels - including small capillaries - of the brain.

People with diabetic foot ulcers more likely to die prematurely

People with diabetes who develop foot ulcers are at more risk of dying prematurely than those without the complication, finds a new large-scale study. The researchers say the findings highlight the potential need for improved detection and management of those with diabetes and foot ulcers.

New insights on mechanisms involved in regeneration of insulin-producing cells

Researchers at Cedars-Sinai's Maxine Dunitz Neurosurgical Institute have found that a blood vessel-building gene boosts the ability of human bone marrow stem cells to sustain pancreatic recovery in a laboratory mouse model of insulin-dependent diabetes.

Ranibizumab injections keep those with AMD driving longer

The advanced neovascular, or “wet,” form of age-related macular degeneration (AMD), left untreated, is the most common cause of vision loss among the elderly and a leading reason for their loss of driving privileges. But results of a new study, published in the online version of the journal Ophthalmology, suggest that monthly injections of ranibizumab improve eye chart test results required for a driver’s license, build driver confidence and keep those with AMD driving longer.

Obesity from high-energy diets may impair brain, fuel overeating

"Betcha can't eat just one!" For obese people trying to lose weight, the Lays potato chip advertising slogan hits a bit too close to home as it describes the daily battle to resist high calorie foods.

Galectin-1 drives growth of Kaposi sarcoma tumors

A sugar-loving protein drives the growth of Kaposi sarcoma (KS) tumors, according to a study published on October 1st in The Journal of Experimental Medicine. Interfering with these sugary interactions inhibited growth of Kaposi sarcomas in mice, hinting at the potential for new treatment strategies in humans.

People with SIRT1 genetic variation more likely to develop vibration-induced white finger disease

Vibration-induced white finger disease (VWF) is caused by continued use of vibrating hand held machinery (high frequency vibration >50 Hz), and affects tens of thousands of people. New research published in BioMed Central's open access journal Clinical Epigenetics finds that people with a genetic polymorphism (A2191G) in sirtuin1 (SIRT1), a protein involved in the regulation of endothelial NOS (eNOS), are more likely to suffer from vibration-induced white finger disease.

FDA approves Boston Scientific’s S-ICD system to treat sudden cardiac arrest

The U.S. Food and Drug Administration has granted Boston Scientific Corporation regulatory approval for its S-ICD System, the world's first and only commercially available subcutaneous implantable defibrillator (S-ICD) for the treatment of patients at risk for sudden cardiac arrest (SCA).

Cameron Health receives FDA approval for subcutaneous implantable defibrillator system

The U.S. Food and Drug Administration today approved a heart defibrillator that helps to restore regular heart rhythms with leads that can be implanted just under the skin (subcutaneously) instead of connected directly into the heart.

Cholesterol precursor suppresses inflammatory response genes, causes atherosclerosis

Atherosclerosis - the hardening of arteries that is a primary cause of cardiovascular disease and death - has long been presumed to be the fateful consequence of complicated interactions between overabundant cholesterol and resulting inflammation in the heart and blood vessels.

Researchers identify genetic origins in 10% of aortic valve malformations

Researchers at the Sainte-Justine University Hospital Center and University of Montreal have identified genetic origins in 10% of an important form of congenital heart diseases by studying the genetic variability within families.

Karolinska Institutet scientists discover new approach to treat type II diabetes

An international team of scientists, led from Karolinska Institutet in Sweden, have discovered an entirely new approach to the treatment of type II diabetes. The therapy involves the blockade of signalling by a protein known as VEGF-B and this prevents fat from accumulating in the 'wrong' places, such as in muscles and in the heart. As a result the cells within these tissues are once again able to respond to insulin.

Microcirculation secrets could shed new light on risks of heart disease and diabetes

Researchers at the University of Southampton together with colleagues at King's College London have embarked on a unique study that will shed new light on the risk of heart disease and diabetes in later life.

Lonafarnib proves effective for children with progeria

Results of the first-ever clinical drug trial for children with Progeria, a rare, fatal "rapid-aging" disease, demonstrate the efficacy of a farnesyltransferase inhibitor (FTI), a drug originally developed to treat cancer. The clinical trial results, completed only six years after scientists identified the cause of Progeria, included significant improvements in weight gain, bone structure and, most importantly, the cardiovascular system, according to The Progeria Research Foundation (PRF) and Boston Children's Hospital.

Advanced optics system noninvasively maps out network of tiny blood vessels beneath the skin

The trained eye of a dermatologist can identify many types of skin lesions, but human sight only goes so far. Now an international team of researchers has developed an advanced optics system to noninvasively map out the network of tiny blood vessels beneath the outer layer of patients' skin, potentially revealing telltale signs of disease.
