Prenatal Stress Keeps Infants, Toddlers up at Night, Study Says

...unlike medication, none of them are suspect in the least for causing adverse effects to baby. Given prenatally, psychological interventions could instill a whole host of benefits that may carry-over to the child, OConnor said. Still, more clinical research is needed to see how we can best promote heal...

Genomic Analysis Uncovers New Targets for HIV Vaccine

...e new results suggest that for some individuals at least HLA-C is involved in controlling HIV-1. Since HIV-1 appears unable to shut off HLA-C, unlike A and B, HLA-C may represent an Achilles heel of HIV, according to Goldstein, who said that a vaccine could be designed to elicit an HLA-C mediated response ...

One species, many genomes

...w genes. The plan is to decipher the genomes of at least 1001 Arabidopsis varieties. A new instrument, with which the entire genome of a plant can be read in just a few days, is already available. Still missing are the computational algorithms to interpret the anticipated flood of data....

Research identifies protein that signals flowering in squash plants

...is building that the FT protein is responsible, at least in tomato, rice, and the model plant Arabidopsis (which is in the mustard or cabbage family). In research published today in The Plant Cell, researchers Ming-Kuem Lin and William J. Lucas from the University of California, Davis, together with a numb...

Cellular message movement captured on video

...moves and its fibrous structures disappear. “As least by showing that paxillin and actin filaments move together we have some insight into the possibility of how paxillin can transmit information from one region of the cell, such as the periphery, to another region of the cell, such as the nucleus,” sai...

Snoring in children might be an allergic type disease

...n snoring. Almost 60% of these children snored at least once per week including 26% who snored more than three nights per week. This is a very high prevalence in five year old children and is partly due to all of the children having rhinitis which is often found in children who snore. Dr Nat Marshall,...

Loss of stem cells correlates with premature aging in animal study

...to reconstitute tissues in the engineered mice, at least initially. “Think of aging as a slow loss of stem cells, a deterioration of pools of cells that reside in each tissue type,” says Brown. We accelerated the aging process by wiping out a large fraction of these cells prematurely, in one fell swoo...

Studies to find better ways to preserve human eggs, ovarian tissue under way

...hnology showed the approach he uses works well, at least in blood vessels. “Now we want to try this on eggs and ovarian tissue and see if we can develop a robust technology and improve outcomes,” Dr. Song says. Later, researchers will put ovarian tissue preserved both ways into mice to see if it survive...

Longer treatment benefits sleep apnea patients

... suggest that most patients should use CPAP for at least 7.5 hours each night to realize the greatest possible benefits of therapy. "Relationship Between Hours of CPAP Use and Achieving Normal Levels of Sleepiness and Daily Functioning," is published in the June issue of the journal SLEEP. More tha...

Brightening prospects of using fluorescent nanotubes in medical applications

Rising skin cancer rates are more likely to affect wealthy people, says 12-year review

...y than men to suffer from malignant melanoma - the least common, but most serious skin cancer - which averages 186 cases a year. Being well-off was a disadvantage when it came to skin cancer. Women living in affluent areas were 29 per cent more likely than people living in disadvantaged areas to suff...

U-M researchers discover gene switched off in cancer can be turned on

...argeted therapies don’t cure the cancer, we can at least have long-term survival,” he adds. ...

Physicist cracks women's random but always lucky choice of X chromosome

...explanation may have much wider implications as at least 10% of our genes may behave in similar ways as mechanism that "chooses" between X chromosomes. Examples of this range from the immune system to our olfactory apparatus. Coming at the problem from the perspective of a physicist Dr Nicodemi has foun...

Study shows lizard moms dress their children for success

... best when it comes to dressing their children, at least among side-blotched lizards, a common species in the western United States. Researchers at the University of California, Santa Cruz, have found that female side-blotched lizards are able to induce different color patterns in their offspring in respon...

Women well informed about breast cancer, yet lacking knowledge about current treatments

...y (76 percent) of women surveyed said they know at least a fair amount about breast cancer, many remain unaware of the important recent progress made in treatment. Fewer than one out of four (23 percent) women ages 50-65 have heard of new therapies for breast cancer, revealing a gap between awareness and ...

Small, self-controlled planes combine plant pathology and engineering

...n 500 viable colonies of Fusarium, representing at least a dozen species. “For 11 of these Fusarium species, this is the first report of their ability to be transported great distances above the surface of the earth,” Schmale said. “Our work has important implications for the rapid spread of invasive pl...

New findings challenge established views on human genome

...ve been obviously constrained during evolution, at least when examined by current methods used by computational biologists. According to ENCODE researchers, this lack of evolutionary constraint may indicate that many species’ genomes contain a pool of functional elements, including RNA transcripts, tha...

Plants recognize their siblings, biologists discover

...arden plant isn’t as passive as widely assumed, at least not with strangers. Researchers at McMaster University have found that plants get fiercely competitive when forced to share their pot with strangers of the same species, but they’re accommodating when potted with their siblings. The study appears t...

Study finds mix of disease processes at work in brains of most people with dementia

...t 85 percent of the individuals had evidence of at least one chronic disease process, such as Alzheimer’s disease, strokes, Parkinson’s disease, hemorrhages, tumors, traumatic brain injury or others. Comparison of the clinical and autopsy results showed that only 30 percent of people with signs of deme...

454 sequencing identifies HIV drug resistance at early stage

Most low level mutations are undetectable by current resistance testing methods that are used in the clinic. The additional low abundant resistant variants detected by Ultra Deep sequencing were found to be extrem...
