Scientists produce equivalent of test-tube inner ear hair cells

Birds, fish and amphibians can do something that humans and other mammals generally cannot: re-grow damaged or lost inner ear hair cells.

Discovery of new pathway causing cell death related to frontotemporal dementia and ALS

Scientists have discovered a link between a mutated gene and a protein found in dead brain cells of people who suffer from a form of dementia and other neurological disorders.

The jury is in: microRNAs can cause tumors to metastasize

These tiny molecules fine-tune protein production and play a powerful role in biological processes ranging from development to aging. Now scientists have proved that they can prompt otherwise sedentary cancer cells to move and invade other tissues.

New research on glycemic index

In work investigating the reproducibility of glycemic index values, researchers at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University (USDA HNRCA) have reported that multiple glycemic index value determinations (measure of the rate of glucose absorption into the bloodstream) using a simple test food, white bread, resulted in a relatively high level of inter-individual (among different individuals), and intra-individual (within the same individual) variability.

Coping with urinary incontinence

For older adults, increased urinary frequency is fairly common.

Simulation reveals how body repairs balance after damage

Your body goes to a lot of trouble to make sure you stay upright. But when the brain's neural pathways are impaired through injury, age or illness, muscles are deprived of the detailed sensory information they need to perform the constant yet delicate balancing act required for normal movement and standing.

African American and Latino diabetics far less likely to blood sugar under control

Despite decades of advances in diabetes care, African Americans and Latinos are still far less likely than whites to have their blood sugar under control, even with the help of medications, a new nationally representative study finds.

Novel strategy to tackle acute myelogenous leukemia

A novel strategy to hopefully beat into oblivion one of the most aggressive forms of acute myelogenous leukemia combines the strengths of some of the newest leukemia agents, researchers say.

Vaginal brachytherapy improves quality of life after treatment for endometrial cancer

Quality of life after treatment for endometrial cancer can be significantly improved by the use of vaginal brachytherapy, where radiotherapy is delivered internally using a vaginal cylinder, the European Cancer Conference (ECCO 14).

New treatment for fractures

Russian researchers have investigated methods of healing bones without extensive operations, long-term bone fixation or expensive stimulating drugs, using tests on animal subjects.

The cancer burden in the developing world

Only a few years ago cancer was considered to be a disease of westernised, developed countries, but now the burden is increasingly falling on less developed countries, a leading epidemiologist told ECCO 14, the European Cancer Conference.

Internal radiotherapy better than external for quality of life in endometrial cancer patients

Radical research results on the oxidation of vitamin E

Recent research results have challenged conventional understanding of the oxidation of the "radical scavenger", vitamin E. Cutting-edge analysis methods have revealed that the intermediates commonly believed to be involved in the process do not occur.

Scientists say fewer calories equals longer life

Even though scientists already knew at least as far as animals are concerned, that reducing the calorie intake was linked to longevity, they never really knew why.

24 Sep 2007

Past clinical trials of vitamin E fatally flawed

Generations of studies on vitamin E may be largely meaningless, scientists say, because new research has demonstrated that the levels of this micronutrient necessary to reduce oxidative stress are far higher than those that have been commonly used in clinical trials.

Brain atrophy in elderly leads to unintended racism, depression and problem gambling

In a study appearing in the October issue of Current Directions in Psychological Science, University of Queensland psychologist, Bill von Hippel, reports that decreased inhibitory ability in late adulthood can lead to unintended prejudice, social inappropriateness, depression, and gambling problems.

Two genes in mammalian cells act as gatekeepers for cellular longevity

In everything from yeast to primates, a significant decrease in calories can extend lifespan by as much as one-third. But getting under the hood of the molecular machinery that drives this longevity has remained elusive.

Older women more knowledgeable about cholesterol than younger women

Older adult American women are better informed about cholesterol and more likely to monitor it than younger adult women, but gaps remain in cholesterol knowledge and efforts to screen for it adequately, according to results of a national survey released by the Society for Women's Health Research, a Washington, D.C., based advocacy organization.

Genes for osteoporosis

Researchers at Hebrew SeniorLife's Institute for Aging Research (IFAR) have examined close to 100,000 genetic markers for low bone mass and aging to help determine which genes are responsible for the development of osteoporosis and longevity.

Ancient mechanism for coping with stresses also gives cancer a boost

An ancient mechanism for coping with environmental stresses, including heat and toxic exposures, also helps cancerous tumors survive, reveals a new report in the Sept. 21, 2007, issue of Cell, a publication of Cell Press.
