Women feel more pain than men, research shows

...have found that not only do women report more pain throughout the course of their lifetime, they also experience it in more bodily areas, more often and for longer duration when compared to men. There also seem to be differences in how men and women think and feel about their pain. For example, anxiety may aff...

The making of a fat cell

...eneration of fat begins before birth and continues throughout life. The first step in fat production involves proliferation of mesenchymal stem cells, followed by differentiation into fat cell precursors called preadipocytes. Mesenchymal stem cells can differentiate into various cell types, including bone, cart...

Micro RNAs play role in egg making

...t miRNAs tightly control the abundance of proteins throughout the process of oogenesis and fertilization. Using a proteomics tool developed at Carnegie Mellon, the scientists compared maturing fruit fly eggs. One group of eggs was missing a gene essential for producing miRNAs, whereas another group of eggs had...

Techniques available to detect soil that inhibits destructive soybean pest

... Westphal and his research team conducted a survey throughout Indiana to locate nematode-suppressive soils in an effort to make this tool more available and to further study the mechanisms that create its effectiveness against the pathogen. Soybean cyst nematodes, one of a large, diverse group of multicellular...

UNC scientists discover new role for protein as fundamental inhibitor of cell movement

...t aimed at decreasing tumor metastasis, or spread, throughout the body. "I was ecstatic to see these results and to discover that it also regulates the fundamental process of cell migration," said Dr. Tina Leisner, associate professor of pharmacology at UNC and the study's lead author. "CIB1 plays a prominent ...

Tiny roundworm's telomeres help scientists to tease apart different types of aging

...seder's lab. Many cells in our body keep dividing throughout life (e.g., those that line our digestive tract, blood, and immune cells) because they must be replaced over time. When these cells' telomeres reach a critically short length, however, they can no longer replicate. The cell's structure and function b...

OHSU researchers discover potential mechanism to repair brain damage linked to Multiple Sclerosis

...ll of the mature oligodendrocytes that make myelin throughout life. Back's lab provided the team with tissue cultures of immature rat oligodendrocytes. The researchers then applied HA to these cells which indeed kept the immature cells from maturing into myelin-producing cells. In another key experiment, Sherm...

Does manganese inhaled from the shower represent a public health threat?

...ce inside these small nerves, manganese can travel throughout the brain." Elsner and Spangler extrapolated data from rodents to estimate human exposure to manganese during showering. They found that after 10 years of showering in manganese contaminated water, children would be exposed to doses of manganese thr...

Tissue regeneration operates differently than expected

...em cells ?adult stem cells ?play an important role throughout an organism's life. For example, bone marrow stem cells provide for the replenishment of short-lived blood cells. Adult stem cells can be found locally in various tissues and organs, and we have presumed that they are participating in the repair and ...

U-M scientists discover identifying markers for primitive blood-forming stem cells

...ning the inside of blood vessels that carry oxygen throughout bone marrow and the spleen. "The presence of HSCs in sinusoidal endothelium could explain how stem cells are able to enter the bloodstream so quickly," Morrison adds. "It also suggests that endothelial cells produce substances that regulate and nurt...

MBL researchers probe how an ancient microbe thrives and evolves without sex

Color perception is not in the eye of the beholder: It's in the brain

...en, and yellow--were sometimes profusely scattered throughout the retina, and sometimes barely evident. The discrepancy was more than a 40:1 ratio, yet all the volunteers were apparently seeing the same color yellow. "Those early experiments showed that everyone we tested has the same color experience despite ...

Human brain is still evolving

..., are they representative of many other such genes throughout the genome. I would bet, though, that we will find evidence of selection in a lot more genes." Lahn and his colleagues are now working to understand how subtle changes in the sequences of these two genes can alter their function in such a way that w...

Volunteers sought for avian flu vaccine study

...ian influenza, or "birdflu," is of growing concern throughout the world. Human cases, with a high fatality rate, have been reported in Vietnam, Thailand and Cambodia. Public health experts fear that avian flu could lead to a worldwide pandemic if the virus becomes easily transmittable,leading to a public heal...
