Women feel more pain than men, research shows

... which are more predominant in women than men that influences women's experiences of pain. "Chest pain is associated with coronary heart disease, angina and heart attacks, so it is understandable that chest pain is a cause of great anxiety for patients and that anxiety has an important role in the experience o...

Brain networks change according to cognitive task

...amic Causal Modeling, the new method examining the influences between brain regions, indicates that each task preferentially strengthened the influences converging on the task specific regions (LTC for rhyming, IPS for spelling). This finding suggests t...

Tropical Deforestation affects rainfall in the U.S. and around the globe

...n in the Amazon region of South America (Amazonia) influences rainfall from Mexico to Texas and in the Gulf of Mexico. Similarly, deforesting lands in Central Africa affects precipitation in the upper and lower U.S Midwest, while deforestation in Southeast Asia was found to alter rainfall in China and the Balka...

Aquatic plants may hold key to advancing plant disease management

...tinue to provide insight as to how climatic change influences disease development. "Emerging marine diseases, such as coral diseases, are creating a major shift in the marine flora," Schmale said. "Global warming and climate change appear to be increasing the rate at which these diseases spread and intensify," ...

Protein structure key for AIDS, cell function

...ts can now begin to examine how the protein's form influences its molecular functions. "People have been struggling with this for a long time, and we have finally solved it," said Hao. ...

VCU Massey Cancer Center study shows enzyme linked to spread of breast cancer cells

...r Center have found a new signaling component that influences movement of human breast cancer cells toward epidermal growth factor. In the August issue of the Journal of Biological Chemistry, researchers showed that epidermal growth factor, which plays a critical role in breast cancer progression, stimulates s...

'Shifty-eyed' Monkeys Offer Window Into Brain's Social Reflexes

...fting attention to determine if social information influences patterns of brain activity there. In future studies, they plan to alter or disrupt neurons or structures in the social-processing regions of the monkeys' brains, and explore whether the resulting behaviors mimic the symptoms of autism. Also, he said,...

Gambling monkeys give insight into neural machinery of risk

...n of the serotonin system in monkeys to see how it influences risk perception and risk preferences, and whether we see changes at the level of the single neurons that we're studying." What's more, said Platt, the studies with monkeys can guide studies in mice, in which scientists can make genetic alterations i...

Space matters: Estimating species diversity in the fossil record

...e rock record as well. Just as geographic sampling influences diversity counts in the modern landscape, the species-area effect strongly influences counts in the fossil record. Taking this into account will alter historical estimates of species dis...

Scientists find microRNAs regulate plant development

... in regulating plant growth and development. Auxin influences development by affecting the expression of numerous genes that control the processes of cell division and cell expansion in specific plant tissues at specific stages during the plant life cycle - e.g. for leaves, roots, and floral organs to develop i...

Scripps research scientists identify infertility molecule

...agues have discovered a new molecular pathway that influences fertility, at least in mice -- and one that directly affects the ability of mouse embryos to implant in their mother's womb. LPA Receptors and Implantation The pathway that affects implantation involves a particular type of receptor molecule -- a p...

Vitamin A's paradoxical role in influencing symmetry during embryonic development revealed

...ls that is the early embryo, because its signaling influences both the asymmetric arrangement of organs and tissues in the interior of our bodies and the symmetrical pattern of the exterior of the trunk. Belmonte and his Salk colleagues evaluated other signaling pathways that also influence pattern formation -...

Fox Chase study shows that weakened T-cell receptor signals change T-cell lineage

... Ph.D., show that cell-receptor signaling strength influences which course certain immature immune cells will take, suggesting a flexible new model for commitment to one lineage or another. The first, most basic career choice made by precursors of the adaptive arm of the immune system is whether to adopt the B...

At long last, scientists figure out how plants grow

...iri identify TIR1 as the protein that, with auxin, influences how and when plant cells grow and divide. In the same issue, scientists in the United Kingdom report a virtually identical result. "How auxin works has been a holy grail in plant science," said Estelle, who led the research. "This was something even...

Protein helps regulate the genes of embryonic stem cells

...he first step toward understanding how epigenetics influences such occurrences as cancer and birth defects, he a...Magnuson and his colleagues chose to study how eed influences genes in embryonic stem cells because they thought that would be directly applicable to stem cell te...

Viral protein influences key cell-signaling pathway

Effective Cancer Treatments Follow The Clock

...is a tangible difference in the immune system that influences sensitivity.?/p> The findings may well extend to the effects of other anti-cancer drugs, as well as to radiation therapy and may provide a rationale for adjusting the timing of chemotherapy to make it less toxic. “There is one more very important...

Variation in a taste receptor gene influences taste sensitivity of children and adults, accounti...tter taste than those with just one (AP). Genetic influences on bitter taste sensitivity were in some cases modified by age. In individuals with the mixed AP gen...

New insight into people who 'see' colors in letters and numbers

...archers found that the strength of this activation influences the strength of the synesthetic colors. In fMRI, harmless radio waves and magnetic fields are used to map regions of higher blood flow in the brain, which reflects higher activity in those regions. Importantly, the researchers found evidence suggest...

Alcohol's effects on gene expression in the central nervous system

...rget is the central nervous system (CNS), where it influences neurotransmission to produce intoxication. Scientists can now use microarray technology to study brain function gene by gene. Symposium proceedings published in the February issue of Alcoholism: Clinical & Experimental Research address the effect...
