Adenosine News and Research

RSS

Adenosine is a nucleoside composed of a molecule of adenine attached to a ribose sugar molecule (ribofuranose) moiety via a ß-N9-glycosidic bond.

Genetically removing the osteopontin protein prevents lung diseases

In a development that could lead to a novel approach to the treatment of a devastating lung disease, biochemists at The University of Texas Health Science Center at Houston report they are the first to link the osteopontin (OPN) protein to chronic obstructive pulmonary disease (COPD).

Comprehensive CT scan gives better indication of significant coronary artery disease

A team of researchers led by Massachusetts General Hospital (MGH) radiologists has developed a computed-tomography-based protocol that identifies both narrowing of coronary arteries and areas of myocardial ischemia - restricted blood flow to heart muscle tissue - giving a better indication of clinically significant coronary artery disease.

HFSA's annual scientific meeting features four late breaking clinical trials

The 13th Annual Scientific Meeting of the Heart Failure Society of America (HFSA) today featured four late breaking clinical trials at the Hynes Convention Center in Boston.

HFSA's 13th Annual Scientific Meeting focuses on causes and treatment of heart failure

The Heart Failure Society of America's (HFSA) 13th Annual Scientific Meeting convened Sunday, September 13, 2009 at the Hynes Convention Center in Boston. This three-day meeting -- a forum for heart failure specialists to present research findings and advances in treatment -- will address emerging trends in research and new developments in the approach to treating patients with this condition.

Second-hand tobacco smoke exposure results in NAFLD

A team of scientists at the University of California, Riverside has found that even second-hand tobacco smoke exposure can result in nonalcoholic fatty liver disease (NAFLD), a common disease and rising cause of chronic liver injury in which fat accumulates in the liver of people who drink little or no alcohol.

Aptamer nanoflares for molecular detection in living cells

By combining a gold nanoparticle with a unique family of nucleic acids, researchers at Northwestern University have created a new type of intracellular reporting system that with a flash of light reveals the presence and quantity of a wide variety of biologically important molecules. These so-called nanoflares could provide cancer biologists with a highly sensitive method of tracking complex biochemical processes in real time without interfering with those processes.

PROTECT clinical study aimed at the assessment of rolofylline effects

Despite the promising findings of the PROTECT Pilot study, the larger PROTECT trial found no difference with rolofylline versus placebo with respect of the primary and main secondary end-points of the study. Although more rolofylline patients than placebo patients experienced moderate or marked dyspnea improvement at 24 and 48 hours from randomization, this was counterbalanced by a lack of effect on persistent renal impairment. Lastly, the risk of important neurological events was increased in patients on rolofylline.

$201,339 grant offered to a professor for developing a database on enzyme functions

Since the advent of the Human Genome Project an explosion of data has sent the science world scrambling. There is a growing demand to fine-tune genomic codes, which list the "ingredients for life," but do not adequately explain how those ingredients function. A Rutgers University-Camden biochemist is addressing this knowledge gap through the creation of a database for quick "background checks" on all known enzyme functions. Thanks to a National Institute of Health grant, Peter Palenchar, an assistant professor of chemistry at Rutgers-Camden, will categorize decades-worth of scholarship on enzymes into a database, beginning with those that bind to molecules that contain adenosine.

University of Maryland researchers perform a genome-wide association study of ADP-stimulated platelet aggregation

Patients with a certain genetic variation who received the antiplatelet drug clopidogrel had a decreased platelet response to treatment and among those who had percutaneous coronary intervention (procedures such as balloon angioplasty or stent placement used to open narrowed coronary arteries) had an increased risk of having a cardiovascular event in the following year than patients who did not have this variant, according to a study in the August 26 issue of JAMA.

New research results reveal that two Parkinson genes can maintain the mitochondrial functions

Parkinson's disease is caused by the degeneration of neurons in the midbrain. The mechanisms leading to the loss of these neurons, however, are largely unknown. Recent research revealed that about ten per cent of cases are caused by defects in so-called Parkinson-associated genes. Furthermore, mitochondria, the cellular powerhouses, seem to play a major role. New results from researchers at the LMU Munich under the lead of associate professor Dr. Konstanze Winklhofer and Professor Christian Haass connect both phenomena, showing that two Parkinson genes maintain the function of mitochondria.

Protein regulates movement of mitochondria in brain cells

Scientists have identified a protein in the brain that plays a key role in the function of mitochondria - the part of the cell that supplies energy, supports cellular activity, and potentially wards off threats from disease.The discovery, which was reported today in the Journal of Cell Biology, may shed new light on how the brain recovers from stroke.

Snoring and sleep apnoea damage the brain

Australian researchers have found that the effects of sleep apnoea on the brain of a sleeping patient are far worse than previously thought.

Schering-Plough starts patient enrollment in phase 3 trial for Acadesine

Schering-Plough Corporation today announced the start of patient enrollment in RED-CABG, the Phase 3 Trial for acadesine, an investigational, potentially first-in-class adenosine regulating agent (ARA). Acadesine was licensed from PeriCor Therapeutics, Inc., a privately held specialty biopharmaceutical company.

Some orthodontic appliances more prone to bacteria

Researchers at the Oregon Health & Science University School of Dentistry have found the majority of patients with self-ligating orthodontic brackets retain fewer bacteria in plaque than patients with elastomeric orthodontic brackets.

RNA interference can be used to silence genes selectively - potential for Huntington's disease therapy

Howard Hughes Medical Institute researchers have designed tiny RNA molecules that shut off the gene that causes Huntington's disease without damaging that gene's healthy counterpart, which maintains the health and vitality of neurons.

Researchers identify molecule that helps the sleep-deprived to mentally rebound

Sleep experts know that the mental clarity lost because of a few sleepless nights can often be restored with a good night's rest. Now, UT Southwestern Medical Center researchers have identified a key molecular mechanism that regulates the brain's ability to mentally compensate for sleep deprivation.
