Human impact on health of soil, and impact of unhealthy soil on society are intertwined, says LSU researcher

It may sound counterintuitive, but LSU Associate Professor of Chemistry Robert Cook has made a career out of studying the ways organic materials found in the environment, including soils, can either get dirty or stay clean. In fact, the National Science Foundation, or NSF, was so impressed with his efforts that the funding institute awarded Cook one of its most prestigious awards - the NSF CAREER award.

Study finds unhappy families unhappy in two distinct ways

Contrary to Leo Tolstoy's famous observation that "happy families are all alike; every unhappy family is unhappy in its own way," a new psychology study confirms that unhappy families, in fact, are unhappy in two distinct ways. And these dual patterns of unhealthy family relationships lead to a host of specific difficulties for children during their early school years.

Study on how cellular defence systems keep themselves in check from damaging cells themselves

When cells are attacked by bacteria they use all means at their disposal to defend themselves. But cellular defence systems can damage the cells themselves and so need to be kept tightly in check. Recent results help us to understand how this is done and give pointers to new ways of combating disease. Matthias Farlik in the group of Thomas Decker at the Centre for Molecular Biology of the University of Vienna (Max F. Perutz Laboratories) and Mathias Müller of the University of Veterinary Medicine, Vienna have published these findings in the current issue of the journal "Immunity".

Study compares denture stomatitis genes with whole transcriptome for salivary biomarker analysis

The goal of the study was to compare whole-transcriptome, mucosal gene expression in Candida albicans (a parasitic fungus that can infect the mouth) associated chronic denture stomatitis to that of healthy oral mucosa and perform proteomic analyses of potential salivary biomarkers. Denture stomatitis is a condition in which the mucosa underneath a denture becomes inflamed and sometimes painful.

Severe exposure to trauma, loss of family members, and domestic violence very stressful on Sri Lankan children

Two studies on children in Sri Lanka who survived the 2004 tsunami and ongoing civil war there found that it's not these stressful events alone that contributed to the youths' psychological health, but also daily stressors like domestic violence that are exacerbated by traumatic events and continue after the disasters.

Researchers develop new strategy for treating multiple myeloma

Multiple myeloma is one of the most common blood cancers, and at present considered to be incurable. In a new study from Uppsala University, researchers now present a conceptually new model for the development and progression of multiple myeloma. The study was done in collaboration with Vrije Universitet Brussels and is published in the July edition of the on-line journal PLoS ONE.

Restricted diet can extend lifespan: Study

New research being presented this week is giving scientists new insight into why a restricted diet can lead to a longer lifespan and reduced incidence of age-related diseases for a wide variety of animals. Scientists have known for some time that a restricted diet can extend the lifespan of certain animals but this work shows how it affects ageing mechanisms - and significantly has also shown that the effects occur even if the restricted diet is adopted later in life.

FDA confirms GRAS status for Ajinomoto's AjiGRAS-Leucine

Ajinomoto AminoScience LLC (AAS) today announced that it has confirmed GRAS (Generally Recognized As Safe) status of its AjiGRAS-Leucine, meeting the safety standards demanded by the US Food and Drug Administration (FDA). As the only formulation of Leucine currently with FDA acknowledged GRAS status, Ajinomoto's AjiGRAS-Leucine is the first amino acid to be allowed as an ingredient for use in conventional foods like non-milk and milk based meal replacements, sports and isotonic beverages, vitamin enhanced waters, and meal replacement bars, at levels of 0.5 to 3 grams per serving.

Studying retrovirus assembly can help new drug development for infection control

How a retrovirus, like HIV, reproduces and assembles new viruses is different than previously thought, according to Penn State College of Medicine researchers. Understanding the steps a virus takes for assembly could allow development of a way to prevent the spread of retroviral diseases. The team studied a chicken virus called Rous sarcoma virus that causes cancer in chickens and is similar to HIV.

Penn researchers reverse cognitive decline in fruit flies with Alzheimer's gene mutation

Investigators have found that fruit fly (Drosophila melanogaster) males -- in which the activity of an Alzheimer's disease protein is reduced by 50 percent -- show impairments in learning and memory as they age. What's more, the researchers were able to prevent the age-related deficits by treating the flies with drugs such as lithium, or by genetic manipulations that reduced nerve-cell signaling.

Study reveals improved process to obtain, store RNA from lung tumor biopsies

Analyzing the genes expressed by cancer cells allows for a better understanding of that patient's specific disease and in turn, a more personalized approach to treatment. But obtaining the RNA from a tumor in the lungs in order to conduct the genetic analysis is a challenging prospect. Currently, lung cancer researchers are limited to using RNA extracted from early-stage tumors removed during surgery. The small quantities of tissue extracted during routine diagnostic biopsies have not been useful to researchers, due to their small size and the variety of ways they have been processed.

DNA copying error in autism sufferers discovered

Rubicon winner Dalila Pinto discovered a copying error in the DNA of trial subjects who suffered from autism or a similar condition. Some segments of their DNA were copied either once too often or missed out of the copying process. This is a highly promising result from the world's largest investigation into autism. The top journal Nature placed the results online on 9 June.
