Fertility drugs given 'all-clear' in new study

...s-and-oranges comparison, because there are always fewer birth defects in children conceived spontaneously." The earlier study also compared different age groups between the control and treatment. The new study by Dr. Tulandi, Dr. Robert Casper from Department of Obstetrics and Gynecology at the Universit...

Aspirin reduces cardiovascular risks in men and women -- but differently

...on of cardiovascular disease. It is estimated that fewer than five percent of the population suffers from the known gastrointestinal side effects of aspirin or are allergic to it, meaning that many more serious cardiovascular events could be prevented if aspirin was more widely used, Berger said In his an...

Expedition discovers marine treasures

... of fish species recorded reached 200, compared to fewer than 50 before the expedition. The unprecedented richness of marine life and vulnerable status of the atoll's coral beds make Saba Bank a prime candidate for designation as a Particularly Sensitive Sea Area (PSSA) under the International Maritime Or...

How nerve cells stay in shape

... Staufen2-deficient nerve cells have significantly fewer actin fibres than normal synapses. The mRNA for actin is normally transported into dendrites and locally translated into protein there. If there is no Staufen2 to function as a transport protein in the nerve cells, a lesser amount of mRNA makes it to...

Protein 'nanosprings' most resilient found in nature

...ignificant role in the function of proteins having fewer repeats. "Ankyrins appear to have a very unusual structural design ?consisting of short anti-parallel alpha helices that self-assemble into stacks -- that allows them to quickly and robustly unfold and refold," Bennett said. "It's hard to believe, b...

Weizmann Institute suggests that immune cells help to maintain cognition and brain cell renewal

...ls and other important immune cells. Significantly fewer new cells were formed in those mice. On repeating the same experiment, this time with mice possessing all of the important immune cells except for T cells, they again found impairment of brain-cell renewal, confirming that the missing T cells were an...

Breast implants not associated with cancer risk, study reports

...ntified 180 cancers in women with breast implants, fewer than the 193.1 predicted to occur in this population. Cosmetic implants were not associated with an increased risk of cancer overall. Women with implants had an increased incidence of lung cancer (20 cases observed, 9.1 cases expected) and a decrease...

Rhinos clinging to survival in the heart of Borneo, despite poaching

...believed to be extinct. There are believed to be fewer than 300 Sumatran rhinos left in the world and they are considered one of the most endangered rhino species because of the intensity of poaching. Sumatran rhinos are only found in widely scattered areas across peninsular Malaysia, Borneo and the Indo...

Salmonella caught red-handed

...id and diarrhoea ?shows clearly that there are far fewer than expected possible points of attack for developing urgently needed antibiotics. It is also now obvious that increasingly ineffective antibiotics ought to be replaced by similar, but not identical, active principles. This points the way for future...

Patients now surviving once-fatal immune disease

...d or excellent; 35 (86 percent) of patients missed fewer than 10 days of work or school due to illness in the past year; and 18 (44 percent) reported they had not missed any work or school. Thirteen of the 41 patients reported that they had chronic lung disease, and 33 indicated that they had one or more...

World shark attacks dipped in 2005, part of long-term trend

...istics were kept, he said. There also were simply fewer sharks to attack people, a result of a decline in populations caused by overfishing of the carnivorous creature, which generally is slow to reproduce, Burgess said. "It appears that humans are doing a better job of avoiding being bitten, and on the ...

It's in the genes: Study opens door to new treatment of the blues

...ial for the development of new drug therapies with fewer side effects. "We have made great progress in our understanding of how antidepressants work, but despite years of research, our knowledge of the changes that these drugs induce in the brain is rudimentary," Bolanos said. "Though available treatments...

Component in soy products causes reproductive problems in laboratory mice

Sex: It's costly but worth it. Just ask a microbe

...onditions, lack of water, extreme temperatures and fewer nutrients," says Xu. There may be other benefits, too. "Every time DNA replicates and the microbes reproduce, mutations are introduced. While some mutations may be beneficial, most have no effect or are deleterious," says Xu. "Through mating and se...

Insects and mammals share common fat-building pathway, study suggests

.... "Though seemingly obvious--anything that causes fewer fat cells should reduce weight gain and its consequences ?this is not necessarily so." Extra calories have to go somewhere, he said. If fat formation is blocked, lipid deposits may instead build in other parts of the body, such as muscle or liver. "T...

Relationship of brain and skull more than just packaging

...olution. Vertebrate evolution shows a trend toward fewer skull and jaw bones and loss of some intercranial joints. While craniosynostosis is considered a pathology in modern humans, it shares with evolutionary history a reduction in cranial elements and coincident changes in the shape of the skull and brai...

The diversity of marine life in the Gulf of Maine region is much greater than previously thought

For the first time: Longevity modulated without disrupting life-sustaining function

... life focused on reproduction for a long life with fewer progeny and a tendency to halt larval development and enter a dormant, hibernation-like stage in which they can hang on for months but don't reproduce. Unless Smk-1 is missing, that is. Without Smk-1 to provide guiding assistance, DAF-16 is unable...

Nobelist discovers antidepressant protein in mouse brain

... mice. Compared to control mice, knockout mice had fewer receptors at the cell surface, reduced serotonin signaling, decreased responsiveness to sweet reward, and were less mobile, behaviors which are considered depression-like. Also, the 5-HT1B receptors of p11 knockout mice were less responsive to seroto...
