UF Researchers Map Bacterial Proteins That Cause Tooth Loss

...s study, they used cutting-edge molecular research techniques to map all the proteins ?known as the proteome ?produced by P. gingivalis. Ultimately, the researchers were able to fill hundreds of gaps in the organism’s sequence of roughly 2,000 proteins. “The approach used in this study is very exciting,?said H...

Key Trigger Of Opioid Withdrawal Symptoms Found

Molecular models advance the fight against malaria

... team was then able to apply computerized modeling techniques to illustrate exactly how the drug interacted with the cytochrome bc1 complex ?the respiratory enzyme the parasites need to live and multiply -- on a molecular level. With this new understanding of how the parasites were able to counter the effects o...

Transgenic plants remove more selenium from polluted soil than wild plants, new tests show

...ed or eliminated," said Banuelos. Terry said that techniques now being developed by plant geneticists -- such as modifying chloroplast DNA rather than nuclear DNA -- will eventually reduce the need for such constant monitoring. Since chloroplast DNA is maternally inherited, there is little risk of pollen trans...

New lab technique identifies high levels of pathogens in therapy pool

...mes more sensitive than standard microbe-culturing techniques used at most indoor pool facilities today, the researchers said. The two-year study involved a molecular survey of a common RNA gene found in all life forms, eventually matching some cloned and sequenced bacteria to the "Mycobacterium avium" bacteriu...

New drug shows promise as powerful anticancer agent

...human tumors, and studies using various laboratory techniques have shown that inhibition of Plk1activity leads to cell death. "Because all signaling pathways that have gone awry in a cancer cell ultimately affect cell proliferation, a reasonable approach to cancer therapy is to develop inhibitors that block the...

Chemicals in tattoo inks need closer scrutiny

...een no previous studies, they are using analytical techniques that can test for a wide variety of chemical components, rather than looking for a specific group of compounds. "At this point in the study, we have determined that the inks do in fact vary in composition from manufacturer to manufacturer and from c...

Technique may allow cancer patients to freeze eggs, preserving fertility before starting treatment

...ilized. U-M researchers looked beyond traditional techniques to a method of freezing cells called vitrification. This cryopreservation technique allows the eggs to be cooled fast enough that the transformation from liquid to solid is instantaneous. No ice crystals form and the consistency resembles a viscous g...

PET/CT can identify new cancer lesions at early stage, allowing for prompt treatment

...uthor), and Pavni V. Patel, M.D. Results of modern techniques such as PET/CT can be "potentially medically significant and relevant," said Wahl. PET is a powerful medical imaging modality that noninvasively traces molecular and physiologic processes in the body. Currently, the most common use of PET is for who...

Global analysis of membrane proteins
