UF Researchers Map Bacterial Proteins That Cause Tooth Loss

...of Washington. They describe their findings in the current issue of the journal Proteomics. “Determining which proteins are expressed in greater levels in the mouth has allowed us to gain clues as to how P. gingivalis might be causing disease, and what we might be able to do with drugs or vaccines to preven...

World's largest rainforest drying experiment completes first phase

...hough it is difficult to imagine a reversal of the current trend in rainforest drying, it is important to understand the forest's response to this scenario nonetheless. What types of trees will invade the forest that has now been "released" from its imposed drought? And are the trees that survived somehow da...

Gene therapy for Parkinson's disease moves forward in animals

...disease. Levodopa, considered the gold standard of current treatment, enables the brain to replenish its dwindling supply of dopamine, sidetracking the destructive course of Parkinson's disease. But eventually the treatment can backfire. "Levodopa generally works great for several years, but then it actuall...

Chemists identify key gene in development of type 1 diabetes

...y, the world's largest scientific society. In the current study, the researchers focused on the formation of the MIF protein (macrophage migration inhibitory factor), a proinflammatory protein that they showed in previous studies is elevated in diabetic animals and may be involved in the cascade of immunolo...

International HapMap consortium expands mapping effort

...sity of SNP "signposts" across the genome from the current average of one every 3,000 bases to about one every 600 bases. "This will help us create a far more powerful HapMap than we ever imagined. We sincerely thank all those who are giving their time, technology and money to help turn this dream into real...

In the current study, the researchers focused on the formation of the MIF protein (macrophage migration inhibitory factor), a proinflammatory protein that they showed in previous studies is elevated in diabetic animals and may be involved in the cascade of immunolo...

Genrate: a generative model that finds and scores new genes and exons in genomic microarray data

...me sequence and find new gene structures. However, current methods rely on separately making threshold-based decisions on intensity of expression, similarity of expression profiles, and arrangements of exons in the genome. We have taken a Bayesian approach and developed GenRate, a generative model that acco...

Antibiotic might fight HIV-induced neurological problems
