Researchers Analyzes Risk Between Hodgkin Disease and Heart Attack Mortality

...lleagues, are needed to help better understand the processes and factors that worsen heart function, especially now that patients in remission are living to older ages when cardiac disease is common," writes John D. Boice Jr., of the International Epidemiology Institute in Rockville, Md. and the Vanderbilt-Ing...

Growth Factors Given With Chemotherapy may Increase Risk of Blood Diseases

... mutated by chemotherapy. Ordinarily, certain cell processes would recognize such damage and instruct the cell to die, but growth factors may save the mutant cell, allowing it to develop into a cancer called acute myelocytic leukemia (AML). There's also concern about the risk of a disease called myelodysplasti...

Lipid Plays Big Role in Embryonic Development

...and primitive ectoderm formation was impaired; all processes worked like a charm when ceramide was restored. They plan to study what unknown roles ceramide may play in mature cells and if it plays a role in some cells losing their direction and becoming cancerous. “There are conditions where a lot of cells...

Ceramide Directs Stem Cells in Embryo

They plan to study what unknown roles ceramide may play in mature cells and if it plays a role in some cells losing their direction and becoming cancerous. 'There are conditions where a lot of cells...

Molecular Link Between Inflammation and Cancer Discovered

Scientists Identify Gene That May Indicate Predisposition To Schizophrenia

... change the expression of CHI3L1 can influence key processes dependent on CHI3L1 levels, knocking out portions of the AKT-mediated signal pathway. The AKT-mediated signal pathway has been shown to be impaired in patients with schizophrenia, and antipsychotic medication may induce AKT activation, to compensate ...

The Latest Gen About the Human Genome

...metabolites are molecules which play a role in the processes that constitute the metabolism in a living being. When all the metabolic reactions form a network it is called a metabolome. "Most medical tests today are based on measuring metabolites in blood or urine. Unfortunately, less than 1% of known metabo...

High-fibre Diets can Bust Breast Cancer

...ers attributed this to the way fibre regulates and processes estrogen, which is present in higher amounts in younger women. Says Professor Janet Cade, "Our study found no protective effect in the older group, but significant evidence of a link in the pre-menopausal women. In addition, post-menopausal women w...

New Test Predicts CLL’s Sensitivity to Experimental Drug

...biting drugs designed to restart the natural death processes thwarted by the survival molecule. Letai said that his group has tested Abbott's investigational compound ABT-737 against cultured CLL cells with striking results. "We've treated CLL samples from several dozen patients, and each has responded to a ...

Carriers With Alzheimer's High Risk Gene Type Age Normally Until the Disease Strikes

... old age,write the authors, "[Alzheimer's disease] processes may occur later in the lifespan and add to normal cognitive aging to produce a dementia syndrome." The study confirmed that carriers of the APOE4 gene type (allele), which confers higher risk for Alzheimer's, are just like other people their age thro...

Hybrid Molecule Causes Cancer Cells to Self-Destruct

...and correct aberrant gene expression patterns, two processes that go awry when cancer occurs. Now that they’ve identified the butyrate-ManNAc molecule as a potential cancer fighter, the Johns Hopkins team members are expanding their research, looking for new drug-delivery methods and preparing for animal test...

Mercury Contamination (Hotspots) Identified

The hotspots are believed to result from complex processes that move atmospherically released mercury through the environment, and from site-specific characteristics such as the high sensitivity of wetlands and forested areas to mercury inputs. Local sources of mercury are also significant. Although mercury ...
