Study: Clinical criteria for mild cognitive impairment is better at predicting Alzheimer's disease

A new Mayo Clinic study found that the clinical criteria for mild cognitive impairment is better at predicting who will develop Alzheimer's disease than a single memory test.

Researchers synthesize molecule to block abnormal protein in cancer cells

In the quest to arrest the growth and spread of tumors, there have been many attempts to get cancer genes to ignore their internal instruction manual. In a new study, a team led by Dana-Farber Cancer Institute scientists has created the first molecule able to prevent cancer genes from "hearing" those instructions, stifling the cancer process at its root.

Alzheimer's treatments may prove effective if started in middle-aged people: Study

Memory lapses that occur with normal aging are a source of worry for many who fear Alzheimer's disease. Now a new Mayo Clinic-led study published in the July 16 issue of the New England Journal of Medicine suggests that the carriers of a common genetic risk factor for Alzheimer's disease begin to have memory declines in their mid-50s, far earlier than previously thought.

Researchers find stress-activating factors can control genes

Stress has become one of the major disease states in the developed world. Researchers from Dr.Klaus Hansen's group at BRIC, University of Copenhagen, have just shown that external factors can stress our cells through the control of our genes. "We found that stress-activating factors can control our genes by turning on certain genes that were supposed to be silenced.

Researchers publish evidence behind evolution of jaws in vertebrates

A half-billion years ago, vertebrates lacked the ability to chew their food. They did not have jaws. Instead, their heads consisted of a flexible, fused basket of cartilage.This week, an international team of researchers led by a faculty member from the University of Colorado at Boulder published evidence that three genes in jawless vertebrates might have been key to the development of jaws in higher vertebrates.

New Concordia research links hormones with attention and learning

Feeling a little sluggish and having trouble concentrating? Hormones might be to blame according to new research from Concordia University published in the journal Brain and Cognition. The study shows that high estrogen levels are associated with an inability to pay attention and learn - the first such paper to report how this impediment can be due to a direct effect of the hormone on mature brain structures.

Key pathway used by malaria parasite to infect human cells identified

Development of an effective vaccine for malaria is a step closer following identification of a key pathway used by the malaria parasite to infect human cells. The discovery, by researchers at The Walter and Eliza Hall Institute in Melbourne, Australia, provides a new vaccine target through which infection with the deadly disease could be prevented.

Playing video games may help children become laparoscopic surgeons

Playing video games for hours on end may prepare your child to become a laparoscopic surgeon one day, a new study has shown. Reorganisation of the brain's cortical network in young men with significant experience playing video games gives them an advantage not only in playing the games but also in performing other tasks requiring visuomotor skills. The findings are published in the October 2010 issue of Elsevier's Cortex.

Peer-reviewed paper on power of iridoids in Tahitian Noni Bioactives published in Wiley Online Library

Tahitian Noni International's Brett West, director of noni benefits research, and his team have recently published another peer-reviewed paper on the power of iridoids in Tahitian Noni® Bioactives™. The paper, published just this month in the Wiley Online Library, concludes that iridoids are the major source of bioactivity in Tahitian Noni Bioactives, and that substantial iridoids can be found in the noni fruit, leaf, root, seed, and flower of noni plants.

MTHFD1L gene may increase risk of developing late-onset Alzheimer's disease

Researchers have identified a gene that appears to increase a person's risk of developing late-onset Alzheimer's disease, the most common form of the disease. The gene, abbreviated as MTHFD1L, is on chromosome six, and was identified in a genome-wide association study.

Researchers discover new signaling pathway for cell development

Researchers at UCLA's Jonsson Comprehensive Cancer Center have discovered a new cell signaling pathway that controls cell growth and development, a pathway that, when defective, helps promote the formation of several major forms of human cancer, including lymphoma and leukemia.
