A new magnetic resonance (MR) imaging technique using hyperpolarized helium lights up the lungs airways, providing, for the first time, clear resolution of even the smaller, seventh-generation airways. The technique, dynamic hyperpolarized 3He (helium) MR imaging, should help physicians better understand and treat asthma, as well as other chronic obstructive pulmonary diseases. Researchers from Brigham and Womens Hospital reported their findings in the May issue of the journal Radiology.
Cooking with sesame oil in place of other edible oils appears to help reduce high blood pressure and lower the amount of medication needed to control hypertension, researchers reported today at the XVth Scientific Meeting of the Inter-American Society of Hypertension. The meeting is co-sponsored by the American Heart Associations Council for High Blood Pressure Research.
Using sesame oil as the sole cooking oil for 60 days along with drug treatment lowered patients blood pressur
University of Toronto researchers have developed a hybrid plastic that can produce light at wavelengths used for fibre-optic communication, paving the way for an optical computer chip.
The material, developed by a joint team of engineers and chemists, is a plastic embedded with quantum dots – crystals just five billionths of a metre in size – that convert electrons into photons. The findings hold promise for directly linking high-speed computers with networks that transmit information using
A group of researchers from The Scripps Research Institute (TSRI) have discovered rare genetic mutations in a subset of people who come down with a particular kind of severe sepsis, an acute and often deadly disease.
These rare mutations in a human gene called TLR4 lend susceptibility to meningococcal sepsis, which strikes over 2,500 people a year in the United States. About half of those who contract meningococcal sepsis are younger than the age of two, and the disease has an overall case
Researchers at Oxford University’s Department of Biochemistry have developed methods for making RNA duplexes and single-stranded RNAs of desired length and sequence. This exciting technology is most applicable to commercial RNA providers and companies with large in-house requirements for RNA molecules as it will greatly increase cost-effectiveness.
Small interfering ribonucleic acids (siRNAs) are powerful laboratory tools for directed post- transcriptional gene expression knockdown and inhi
The Ntumu (the Beti-Fang), live in the equatorial forest in southern Cameroon, in the north of Gabon and of Equatorial Guinea. They practice a semi-nomadic slash-and-burn form of agriculture. Their farming is highly diversified, mainly of food crops (such as cassava, plantain banana, sweet potato, yam and taro) but they also produce cash crops (cacao, groundnuts). When they clear a plot (1 ha on average), the Ntumu systematically spare certain trees, generally about 15 whatever cutting methods or imp
