Acrylamide exposure impairs blood-cerebrospinal fluid barrier function

2014-08-25
(Press-News.org) The blood-brain barrier prevents xenobiotics from entering the central nervous system. Growing evidence indicates that neurotoxins, such as tributyltin, manganese and nanoparticles, may disrupt the function of the blood-brain and blood-cerebrospinal fluid (CSF) barriers. Previous studies show that chronic acrylamide exposure leads to central and peripheral neuropathy. However, very few studies have focused on the effects of acrylamide exposure on these barriers. Prof. Yanshu Zhang and co-workers from Hebei United University in China found that acrylamide exposure damages the blood-cerebrospinal fluid barrier and impairs secretory and transport functions. These changes may underlie acrylamide-induced neurotoxicity. The research achievements have been published in the Neural Regeneration Research. INFORMATION:

Deploying exosomes to win a battle of the sexes
2014-08-25
There are many biological tools that help animals ensure reproductive success. A new study in The Journal of Cell Biology provides further detail into how one such mechanism enables male fruit flies to improve their odds by stopping females from mating with other flies. In addition to sperm, semen carries products that foster sperm survival, promote egg fertilization, and serve other functions that optimize a male's chances of passing along his genes. In male fruit flies, for example, reproductive accessory glands (thought to be equivalent to the prostate gland in humans) ...

Changes in the eye can predict changes in the brain

Changes in the eye can predict changes in the brain
2014-08-25
Researchers at the Gladstone Institutes and University of California, San Francisco have shown that a loss of cells in the retina is one of the earliest signs of frontotemporal dementia (FTD) in people with a genetic risk for the disorder—even before any changes appear in their behavior. Published today in the Journal of Experimental Medicine, the researchers, led by Gladstone investigator Li Gan, PhD and UCSF associate professor of neurology Ari Green, MD, studied a group of individuals who had a certain genetic mutation that is known to result in FTD. They discovered ...

Large-scale study focuses on heavy smokers

2014-08-25
It is a fact that smoking is harmful and associated with deadly diseases such as cancer and cardiovascular disease. Researchers also know that smokers die earlier than non-smokers. But a study that sheds light on the direct causal relationship between smoking and mortality by investigating genes has never been published before: – We have studied 55,568 individuals, including 32,823 smokers who we followed for ten years. 3,430 died during this period. The epidemiological studies were supported by genetic analyses, and the conclusion is clear. Smoking is associated with ...

APOB, a gene involved in lipid transport, linked to cases of familial extreme longevity

2014-08-25
In a recent report in Aging Cell, a multidisciplinary team of Spanish scientists, led by Tim Cash and Manuel Serrano at the Spanish National Cancer Research Centre (CNIO), identify rare variants in the APOB gene in several families where exceptional longevity (>100 years of age) appears to cluster. Investigators identified three Spanish families with at least two siblings of around 100 years of age and they sequenced their genes in the hope of finding rare variants that could be associated with extreme longevity. Remarkably, only one gene was found carrying rare variants ...

Anticipating eperience-based purchases more enjoyable than material ones

2014-08-25
To get the most enjoyment out of our dollar, science tells us to focus our discretionary spending on trips over TVs, on concerts over clothing, since experiences tend to bring more enduring pleasure than do material goods. New research shows that the enjoyment we derive from experiential purchases may begin before we even buy. The findings are published in Psychological Science, a journal of the Association for Psychological Science. This research offers important information for individual consumers those who are trying to "decide on the right mix of material and experiential ...

Singaporean university launches world's 1st ZigBee-based inter-satellite comms system

Singaporean university launches worlds 1st ZigBee-based inter-satellite comms system
2014-08-25
Engineers at the Nanyang Technological University in Singapore have successfully piloted the world's first ZigBee-based inter-satellite communication system. The team at the Satellite Research Centre launched the VELOX-I, which consists of a nanosatellite weighing 3.5 kg and a piggyback picosatellite weighing 1.5 kg, from the two highest points on campus. Both miniature satellites were configured with a ZigBee wireless network and equipped with small sensor nodes that perform functions such as local sensing, distributed computing and data-gathering. Designed to evaluate ...

UNC Lineberger researchers develop new approach to identify 'drivers' of cancer

2014-08-25
CHAPEL HILL, NC – UNC Lineberger Comprehensive Cancer Center researchers have developed a new integrated approach to pinpoint the genetic "drivers" of cancer, uncovering eight genes that could be viable for targeted breast cancer therapy. The study, published online August 24 in Nature Genetics, was authored by Michael Gatza, PhD, lead author and post-doctoral research associate; Grace Silva, graduate student; Joel Parker, PhD, director of bioinformatics, UNC Lineberger; Cheng Fan, research associate; and senior author Chuck Perou, PhD, professor of genetics and pathology. These ...

Nursing home care improves with culture change

2014-08-25
PROVIDENCE, R.I. [Brown University] — If a nursing home makes an extensive investment in "culture change" it will see improvements in quality of care, according to a new study led by Brown University gerontology researchers. Culture change is a rethinking of nursing home operations and structure to allow a more residential lifestyle for residents, more resident choice in schedules and activities, and more front-line staff input into care management. Residents, for example, may become able to decide when to go to lunch and nurse's aides may get a seat at the table in designing ...

Latino children make greatest gains in NC Pre-K

2014-08-25
A new summary of 12 years of research on North Carolina's pre-kindergarten program for at-risk 4-year-olds shows that "dual-language learners" make the greatest academic progress in the program. According to the report from the Frank Porter Graham Child Development Institute (FPG), while students in NC Pre-K advance across all spheres of learning, the program is especially beneficial for the state's dual-language learners. "On the whole, children in NC Pre-K exceed normal expectations for the rate of developmental growth, both while in the program and afterward in kindergarten," ...

Core mechanism for root growth identified

Core mechanism for root growth identified
2014-08-25
During plant growth, dividing cells in meristems must coordinate transitions from division to expansion and differentiation. Three distinct developmental zones are generated: the meristem, where the cell division takes place, and elongation and differentiation zones. At the same time, plants can rapidly adjust their direction of growth to adapt to environmental conditions. In Arabidopsis roots, many aspects of zonation are controlled by the plant hormone auxin and auxin-induced PLETHORA transcription factors. Both show a graded distribution with a maximum near the root ...
