Surprising findings reported about iron overload

...eposition occurs due to inadequate control of iron absorption by the small intestine. The first major report of findings in the five-year, 100,000-person study will be published tomorrow, April 28, in The New England Journal of Medicine (NEJM). The University of Alabama at Birmingham received $3.1 million of s...

Reducing malarial transmission in Africa

...gimen, and as it also needs oily food for adequate absorption there might be inadequate drug levels in the blood of many treated individuals. The authors conclude that although co-artemether as a first-line treatment is not likely to reduce overall transmission of Plasmodium falciparum within the community it m...

Iron exporter revealed that may explain common human disorder

... iron exporter that functions in key sites of iron absorption and release in the body. The findings suggest that the iron accumulation seen in those with hemochromatosis may stem from a loss of control over iron export through ferroportin, the researchers said. "Iron is essential in the body and abundant in th...

Alzheimer's cognitive decline slowed

...bjects showed significant increases in the brain's absorption of a radioisotope called 18-fluorodeoxyglucose, an indicator of increased metabolic activity in the brain. The researchers noted that the increase was observed in most cortical regions that receive cholinergic input from forebrain nerve cells called ...

...od pressure, treating cancer and increasing oxygen absorption in lung tissue. Czernuszewicz's research is focused on the roles of salivary nitrophorins in storing and releasing NO and binding histamine by using resonance Raman spectroscopic techniques as a probe of molecular structure. # Yuriy Fofanov, assista...

Findings have implications for tracking disease, drugs at the molecular level

...visible light using a technique called multiphoton absorption induced luminescence (MAIL). The most efficient gold nanoparticles could be observed at laser intensities lower than those commonly used for multiphoton imaging, in which specific tissues or cells -- cancer cells, for example -- are fluorescently-la...

Insulin pulses keep the liver lean

...he pancreas produces insulin, which stimulates the absorption of sugar and fat by the liver," Najjar said. "But in today's Western society, large portions and frequent munching may lead insulin levels to remain high all the time. In that case, the liver no longer perceives pulses of the hormone and becomes resi...

UCLA researchers identify key enzyme linked to childhood blindness

...elated to vitamin A, which is converted upon light absorption to all trans retinaldehyde in a process called photo bleaching. This conversion is the first step in visual perception. Photo bleaching leaves the rhodopsin insensitive to light until the all trans retinaldehyde is converted, or "isomerized," back i...

Anti-cancer Compound In Beer Gaining Interest

...Most beer has low levels of this compound, and its absorption in the body is also limited. But if ways can be developed to significantly increase the levels of xanthohumol or use it as a nutritional supplement - that might be different. It clearly has some interesting cancer chemopreventive properties, and the ...

Breath of the dragon: ERS-2 and Envisat reveal impact of economic growth on China's air quality

...reflectivity of the surface, as well as having the absorption or emission of stratospheric and upper atmospheric species situated between the troposphere and the instrument. "First with GOME and now much better with SCIAMACHY we are demonstrating it can be done. The success so far is an important step on the ...

New evidence questions the simple link between prion proteins and madcow disease

...condly, they looked in more detail at the route of absorption in the gut. Using surgically modified sheep, they loaded a small area of the gut with a fluid mixture containing 0.5 grams of scrapie infected brain containing a large amount of the disease specific variant of the PrP protein and watched how it wa...

Carbon nanotube absorption measured in worms, cancer cells

...gan researchers have discovered how to measure the absorption of multi-walled carbon nanoparticles into worms and cancer cells, a breakthrough that will revolutionize scientists' understanding of how the particles impact the living environment. A team led by U-M chemical engineering professor Walter J. Weber ...

Heart-healthy compound in chocolate identified

...ntake of certain flavanols present in cocoa, their absorption into the circulation and their effects on cardiovascular function in humans," said UC Davis biochemist Hagen Schroeter, who co-authored the paper along with cardiologist Christian Heiss of the Heinrich-Heine University.

Alternatives to the use of nitrate as a fertiliser

...n the pea plant there is greater regulation of the absorption of ammonia at the roots and control of the ammonium levels, above all in the leaf tissue. Moreover, important changes are observed in relation to the carbon and nitrogen of the majority aminoacids (asparragine in the pea and glutamine in spinach). Wi...

Anti-HIV drug has potential to prevent transmission in women

...tudy. Further evaluation is needed to determine if absorption of tenofovir into the bloodstream could be beneficial in enhancing the gel's effectiveness or could cause adverse long-term side effects. The study participants included 84 women, 18 to 45 years of age. Of those, 60 were not infected with HIV and 24...
