Cholesterol Can Cause Burst Arteries

...ed by the plaque rupture into the bloodstream that activates the clotting mechanism. Researchers had compared the crystallization of the cholesterol to putting a plastic bottle of water into a freezer. Over time the water freezes and expands, pushing its way out of the bottle or breaking the bottle altogether...

An Exploration into Erectile Dysfunction in Diabetics

An Enzyme That Turns a One –time Experience into a long-time Memor

...a one-time event into a lasting memory. The enzyme activates genes to express certain proteins. How the enzyme is related to gene expression is currently under study. Current research is trying to identify the genes associated with memory in mice. However researchers say , “The details might be different in m...

Scientists crack mechanism of Leptin-Obesity Hormone

... Dr.Low said that his team found in mice, leptin activates brain cells called proopiomelanocortin neurons and also binds to the receptors on a second type of cell. This duel mechanism of leptin action on two interconnected types of neurons was previously unknown. This mechanism may be an important of...

Gene enchances radiation therapy - A novel approach to fight cancer

...y in Richmond, and colleagues found that radiation activates the EGFR, or epidermal growth factor receptor, which is a part of a repair mechanism that can undo some of the destruction that radiation causes in cancer cells.// The researchers in their experiment injected the mice with mutant form of EGFR, ca...

Identified Protein To Inhibit Cell Migration

...r p21-activated kinase, in cancer cells. When CIB1 activates PAK1, this kinase then inhibits cell migration by adding a phosphate group to a host of other proteins in the cell. Thus, the study suggests that CIB1 may be a likely target for new drug development aimed at decreasing tumor metastasis, or spread, ...

Scientists Identify Cancer Pathway

...cerous cell in place. The build-up of MT1-MMP also activates an enzyme called MMP2, which further degrades the connective tissue.In this way, the cancer cell loses its moorings and can float off to spread around the body. While no one has found v-Src in human cancer patients, a number of other cancers have bee...

New Supplement Found To Be Effective Against Sunburn

...o be more powerful than antioxidant vitamins as it activates the body's productions of its own antioxidants, including catalase and glutathione peroxidase. In a randomized, double-blind study at Center Hospital University in Besan?on, France, researchers induced UV skin burn on the inner-forearms of 50 healt...

Research identifies trigger that sets of Huntingtons disease

...rest. The protein of the Huntingtons disease (HD) activates a regular protein called p53. The p53 can lead to expression of some other genes, that can lead to the full fledged expression of the genes. Researchers from Johns Hopkins University School of Medicine, who had conduced the study, feel that the molec...

Reason for diabetes drug causing edema discovered

...he University of Utah had found that the drug TZDs activates a receptor in kidney called peroxisome proliferator-activated receptor gamma (PPAR). This is situated in the collecting duct of the kidney. The activation of the receptor serves to retain the fluid in the body and causes edema. TZD drugs are general...

Drug for cancer may help restrict premature labor

...acenta produces large amounts of hCG. This hormone activates the number of CG/LH receptors on the smooth muscle cells of the uterus that keeps the uterine walls in a relaxed state. This prevents contractions before time. If the body secrets less amounts of hCG, the uterus can have contractions leading to prema...

New treatment Found To Help Skin Cancer

...ions to make them sensitive to light. A blue light activates the acid and destroys the lesions. Around 18 hours later, she returns for the second treatment. However researchers say this treats only around 85 percent of the pre-cancerous growths and is not a cure. Sun exposure will mean more lesions and more ...

Methamphetamine Users Found To Suffer From Mood Disorders

Methamphetamine is a stimulant drug that strongly activates certain systems in the brain.// The drug is often used to treat obesity and is often addictive. According to the 2000 National Household Survey on Drug Abuse, about 8.8 million people in the United States have tried methamphetamine at least once in t...

Researchers say seven of the patients started gambling within one month after their dosage of the dopamine agonist was increased. All of the patients were i...

Treatment for cholesterol-related illnesses likely with the discovery of receptor in mice

... of excess cholesterol by-products and immediately activates special pathways that remove these toxins. The main problem with the PXR receptors in humans is that they are not activated by the metabolites to trigger an effective response and clear away the cholesterol. The study suggested that harnessing PXR c...
