Mouse brain cells rapidly recover after Alzheimer's plaques are cleared

Brain cells in a mouse model of Alzheimer'sdisease have surprised scientists with their ability to recuperateafter the disorder's characteristic brain plaques are removed.Researchers at Washington University School of Medicine in St. Louisinjected mice with an antibody for a key component of brain plaques,the amyloid beta (Abeta) peptide. In areas of the brain whereantibodies cleared plaque...

Molecule that usually protects infection-fighting cells may cause plaque deposits inside arteries

A molecule that usually protects the body's infection-fighting cells might also contribute to fatty buildups that coat arteries and lead to heart disease, UT Southwestern Medical Center researchers have found. The molecule, called apoptosis inhibitor of macrophage or AIM, inhibits cell death in macrophages, which circulate in the bloodstream and help the body fend off infection and foreign...

Intensive statin therapy may partially reverse plaque build-up in arteries

A study presented today at the American College of Cardiology's 55th Annual Scientific Session demonstrates, for the first time, that very intensive cholesterol lowering with a statin drug can regress (partially reverse) the buildup of plaque in the coronary arteries. This finding has never before been observed in a study using statin drugs, the most commonly used cholesterol lowering tr...

Gene transfer using mutant form of good cholesterol cuts vascular plaque and inflammation

Transfer of a gene that produces a mutant form of good cholesterol provides significantly better anti-plaque and anti-inflammation benefits than therapy using the "normal" HDL gene, according to a mouse study conducted by cardiology researchers at Cedars-Sinai Medical Center and reported in the Oct. 3 issue of the Journal of the American College of Cardiology. Apolipoprotein A-I is a natu...

Bacteria from patient's dental plaque causes ventilator-associated pneumonia

Patients admitted to a hospital's intensive care unit (ICU) already are seriously ill, so the last thing they need is a new infection. Unfortunately, statistics show that as many as 25 percent of all patients admitted to the ICU and placed on ventilators develop pneumonia, which can be fatal. Ventilator-associated pneumonia is a major cause of infection in the hospital, and studies have s...

BacPlaque Agarose from Novagen

Description:Agarose overlays are commonly used in baculovirus plaque assays. Many commercial "DNA grade" agaroses either contain contaminants that are toxic to insect cells or lack the physical characteristics required to obtain good overlays. Novagen's BacPlaque Agarose is pre-qualified in plaque assays and transfections to ensure consistent performance....

Scan correlates susceptible heart plaque

According to a recent study, a combined scan identifies unstable areas of plaque in coronary arteries that may signify danger of heart attack in the future. Fatty deposits, known as plaque, set the scene for heart disease. The build up of plaque - atherosclerosis - begins many years before any symptoms occur.// The plaque narrows the arteries, and may eventually crack, instigating formation of a...

Risks of heart attack related to bacteria in gum plaque

Bacteria that live in the sub-gingival plaques can increase the risk of heart attack //for people. The research, which is published in the current issue of Journal of Periodontology, say that people with periodontal disease who have suffered from an acute myocardial infarction or heart attack are also the ones whose total number of periodontal bacteria in sub gingival plaques were high...

Researchers Develop Device For Detecting Atherosclerotic Plaques

Researchers from Cedars-Sinai Medical Center had developed a device that will use light emissions from body tissues to detect the inflammation that is //part of plaque formation in the condition of atherosclerosis. Now, in a study involving laboratory rabbits, a device that stimulates, collects and measures light emissions from body tissues has been able to detect the presence of infla...

Job stress thickens plaque build-up in arteries

Job stress can start taking a toll on people’s cardiac health as early as their early their early 30s, new research shows. People who report high job strain - the combination of heavy demands and little control at the office // – were found to have thicker carotid intima-media thickness (IMT). IMT is considered a reliable way of determining the early stages of atherosclerosis, the narro...

Neck Artery Treatment Apart From Clearing Plaques Boosts Memory

The percentage of Americans suffering from stroke is on the rise. Usually patients underwent a minimally invasive procedure to reduce their risk of a stroke by clearing plaque from neck arteries. //But studies show that this ha unexpected gains in memory and mental skills. The findings of the study were presented at a medical conference in Toronto. But further trials have to confirm the...

Arterial Plaque Significantly Reduced in Women Age 50-59 Taking Hormones, Says New Analysis of Women's Health Initiative Data

Fourth Study to Indicate that Early Use of Estrogen May beCardio-Protective PHOENIX, June 20, 2007 /PRNewswire-USNewswire/ -- A new analysisof Women's Health Initiative data published in the New EnglandJournal of Medicine, shows significant reduction in calcifiedplaque for women aged 50 to 59 using hormone therapy (HT) comparedwith women taking a placebo. This is the first time therelati...

Evidence of Nanoparticles Found in Plaque-Filled Arteries

ROCHESTER, Minn., April 30. 2007-- Scientific evidenceincreasingly links arterial calcification to the presence ofnanosized particles -- so small that some scientists questionwhether a nanoparticle can live and, if so, play a viable role incausing disease. A new Mayo Clinic study cites evidence showing the presence ofnanoparticles near plaque-filled arteries in animal models....
