Survival of heart patients on beta-blockers varies greatly with genetic variation

Survival of heart attack and unstable angina patients placed on beta-blocker therapy corresponds to specific variations in their genes, according to a study by researchers at Washington University School of Medicine in St. Louis and the Mid America Heart Institute in Kansas City. The study appears in the September 28, 2005 issue of the Journal of the American Medical Association. "In our i...

Rare Tibetan antelope listed as endangered

Three-dimensional ultrasound probes built by researchers at Duke's Pratt School of Engineering have imaged the beating hearts of dogs. The engineers said their demonstration showed that the probes could give surgeons a better view during human endoscopic surgeries in which operations are performed through tiny "keyhole" incisions. If the probes prove beneficial in human testing, the advanc...

Research suggests beta agonists may alter the immune system

New research at Wake Forest University School of Medicine suggests that certain inhaled asthma medications ?as well as similar chemicals our bodies produce during times of high stress ?may worsen diseases such as asthma, heart failure and lupus that involve inflammation. The scientific team led by Raymond Penn, Ph.D., and Matthew Loza, Ph.D, found that beta-agonists, such as those used in...

T-beta-RIII joins the fight against breast cancer

Although the soluble factor TGF-beta has been shown to suppress the growth of tumor cells in the early stages of breast cancer, high levels of TGF-beta during the later stages of the disease are associated with a poor outcome. A study using human breast cancer samples and mice, which appears online on December 7 in advance of publication in the January print issue of the Journal of Clinical Inves...

Tibetan antelope slowly recovering, WCS says

Returning from a recent 1,000-mile expedition across Tibet's remote Chang Tang region, Wildlife Conservation Society (WCS) biologist George Schaller reports that the Tibetan antelope -- once the target of rampant poaching -- may be increasing in numbers due to a combination of better enforcement and a growing conservation ethic in local communities. The eight-week journey, which was co-fun...

Purification of Recombinant Flavonone 3beta-Hydroxylase Using Bio-Scale CHT5-1 Hydroxyapatite Column

Flavanone 3b-hydroxylase (FHT), a typical 2-oxoglutaratedependent dioxygenase, catalyzes the 3b-hydroxylation of 2S-flavanones to 2R,3R-dihydroflavonols which are intermediates in the biosynthesis of flavanoids, catechins, proanthocyanidins, and anthocyanidins in plants. To understand the complex reaction mechanism,...

Screening for potential beta 2-adrenergic receptor antagonists using CypHer5E and IN Cell Analyzer 1000

5, a pH sensitive dye, has shown utility in β2-adrenergic receptor agonist screening (1). CypHer5 has been used to obtain dose-response and rank-order potency data for both agonist and antagonist treatment of β2-adrenergic receptor expressing cells (2). For live-cell receptor internalization studies,...

Screening for β2-adrenergic receptor agonists using the pH-sensitive dye,CypHer5, and the IN Cell Analyzer 3000

High-throughput screening for potential targets is a major requirement in drug development and a key application is in the area of receptor activation, particularly G-protein coupled receptors (GPCRs) (1). <P >It is estimated that there are still 100–200 orphan GPCRs of potential therapeutic value requiring identification of...

The combination of monolithic columns and modern HPLC/MS/MS instrumentation for high chromatographic throughput and sensitive detection of beta-agonists

Beta-agonists are group A substances of the European guideline 93/257/EWG (revision 98/536/EG) having an anabolic effect and not licensed. Thus, they have to be determined in veterinarian samples like muscle, liver, retina, and urine. The coupling of High Pressure Liquid Chromatography (HPLC) and Electrospray Ionization Tandem Mass Spectrometry (ESI-MS-MS) seems to be the analytical m...

Beta-Carotene May Aid Diabetics

Abnormal low-density lipoprotein(LPD), lipid composition and anti-oxidant content are associated with an increased liability to oxidation of LDL derived from diabetic patients.//Researchers designed a study to compare the oxidation of LDL drawn from patients with diabetes mellitus to normoglycemic controls. They also sought to follow-up the effects of dietary beta-carotene supplementation...

Calcium-blocker delays atherosclerosis than beta-blockers

Researchers make a comparative study showing that calcium channel blockers are more effective at slowing down atherosclerosis than beta-blockers. In new research, a group of 1,800 patients were assigned to either lacidipine,// a calcium-channel blocker, or atenolol, a beta-blocker. Both drugs are used to treat high blood pressure, but act in different ways. The calcium-channel blocker dec...

Beta-Carotene Linked With Lower Incidence Of Deaths In Elderly

A new study has linked beta-carotene to heart diseases. The correlation states that intake of beta-carotene //shows lower incidence of deaths in elderly with heart diseases. The association between the risk and beta-carotene intake is still significant after considering other risk factors, according to the authors of the study. The finding apparently contradicts previous studies...

Evidence against use of Beta blockers as first choice in the treatment of primary hypertension

Beta blockers have been used widely in the treatment of hypertension and are still recommended as first-line drugs in hypertension guidelines. Moreover, after myocardial infarction and in patients with heart failure, treatment // with beta blockers prevents re-infarction, hospitalisation for heart failure, and premature death. However, a preliminary analysis has shown that atenolol is not...
