Mulkey, DK, Stornetta, RL, Weston, MC, Simmons, JR, Parker, A, Bayliss, DA & Guyenet, PG (2004). Midbrain serotonergic neurons are central pH chemoreceptors...

Malaria mechanism revealed

...ominent target for the development of therapies to control malaria. To explore the molecular basis of the binding of EBA-175 to glycophorin A--with the rationale that such information might reveal strategies for preventing and treating malaria--the researchers used x-ray crystallography to determine the ato...

Genome study of beneficial microbe may help boost plant health

...ing, beneficial microbes such as P. fluorescens to control plant pathogens is called "biological control." Th...the first complete genome sequence of a biological control agent for combating plant diseases. P. fluorescens Pf-5 was discovered two decades ago by Charles R...

Random gene expression may drive HIV into hiding

...e idea that random fluctuations in gene expression control what happens to the cells, the researchers said. To see if this really was the best explanation, they conducted a large array of experimental controls to discount other hypotheses and then created computer programs to model what would happen to the v...

...y binding to GTP or GDP, and how these alterations control bending and flexibility. They found that in GDP-bound tubulin, the contacts between the alpha and beta tubulins within and between dimers are both affected, although in significantly different ways, resulting in a curved protofilament that cannot fo...

Improved statistical tools reveal many linked loci

...chical relationships between two genomic locations control about one in seven yeast expression traits¡Xwhich Storey et al. discovered using their method. Although the group studied yeast, their method can be applied to more complex organisms to search for even larger numbers of linked loci and to provide in...

Mosaic mouse technique offers a powerful new tool to study diseases and genetics

...ore efficient technique that allows researchers to control when and where mutant cells are generated in the fly's body. However, scientists have had a much more difficult time designing mosaic vertebrates, such as mice. The mouse has long been considered an ideal laboratory model for studying human developme...

Morphine for Chest Pain Increases Death Risk

...atients should begin with nitroglycerin therapy to control pain. "Our recommendation is that patients should receive the full dose of nitroglycerin," he said. "Based on our analysis, morphine should be the last resort after else has been tried." While patients with acute STEMI are at higher risk of dying w...

UNC plant researchers discover proteins interact to form hair-trigger protection against invaders

...arance of resisting proteins, RAR1, HSP90 and SGT1 control whether or not the plant is about to recognize that it is under pathogen attack," Holt said. "So the emerging story is that RAR1 and HSP90 keep resistance proteins ready to perceive pathogen signals, and SGT1 probably pulls against these two to send ...

Induced hypothermia can be accomplished using several methods. Surface cooling methods such as cooling blankets placed under and on top of patient...

Researchers extend mouse lifespan by protecting against free radicals

.... They compared the different groups of mice to a control group and found that increased production of catalase could affect the mouse lifespan. The mice with higher catalase levels in the mitochondria, dubbed the MCAT group, had about a 20 percent increase in average and maximum lifespan, or about four and...
