Scientists Discover New Players On The Gene-Activation Team
...ranscription activator. "This research changes and complicates quite a bit our picture of howgene regulation at the level of transcription actually is orchestrated,"Workman comments. "It demonstrates that the process controlling gene expressionis very dynamic, very interactive, and very complicated."...Discovery Of New Large, Predatory Dinosaur Reported In Science
... However, the discovery of Suchomimus in Africa complicates the picture,because Suchomimus appears to be more closely related to the European Baryonyx than to the southern spinosaurids found in Egypt and Brazil. Thesimilarities between the two dinosaurs suggest that Suchomimus' ancestorevolved in the nor...Yale scientists identify genetic form of hypertension in pregnant women
...pertension that develops or worsens with pregnancy complicates about six percent of all pregnancies and is a major public health problem, contributing to pre-eclampsia, a hypertensive disorder of pregnancy that increases both fetal and maternal morbidity and mortality. The causes are largely unknown. A steroid ......been observed worldwide. This increased resistance complicates the ability to treat pneumococcal infections and is focusing greater attention on prevention strategies. Undoubtedly, the availability of the complete genome sequence will provide additional avenues for follow-up studies on the basic biology and path...MIT team probes arsenic and old lakes
...d were exploring occurs in the bottom layer, which complicates sampling. "If the water samples are exposed to oxygen during sampling, the chemistry could change before we'd have a chance to measure it," Senn said. So he and Hemond developed a filtration unit that allowed them to filter water samples while they w...Revealed: How a master protein remodels chromosomes to orchestrate gene expression
...y to fit the genome into a small nucleus, and this complicates the process of gene expression. For a gene to be transcribed, the double-stranded DNA that encodes it has to be unzipped -- hard to do inside tightly wound chromatin. So gene expression depends on molecular machines that rearrange the chromatin, repo...UC Riverside research featured on the cover of JALA
...urnal. Ozkan explained that the presence of glials complicates the neuron cell culture. "Glials tend to interfere when we pattern neurons using microelectrode arrays," she said. "But with technology we have developed in our labs, we were able to position neurons on microelectrodes by sorting glials in such a w...Computer model offers new tool to probe Woburn toxic waste site
...that originally came from the river, which further complicates the overall picture of contamination in the Woburn wells. From month to month, the wells typically produced water that varied from 20 percent river water content to 40 percent. If the river water was contaminated with solvents, or the riverbed contai...New Georgia Tech Biosciences Center assists life-science startup companies
...operate within a regulated environment, which also complicates commercialization. For example, companies may need FDA approval before they can take their product or service to market. "Most products must undergo extensive pre-marketing testing," Herron adds. "The ultimate commercial product depends on the outco......ls to glucocorticoids is a common development that complicates the management of chronic inflammatory diseases. In the February 16 issue of the Journal of Clinical Investigation Paul Rothman and Daphne Tsitoura from Columbia University report that it is enhanced MEK/ERK signaling that promotes glucocorticoid r...
