Researcher studies, treats military with 'silent disease'

...at were given before 1990 because a good screening tool wasn't available prior to then. The servicemembers Sjogren treats most often report that they contracted it through blood products because they were transfused at an earlier time or because they used IV drugs before they joined the military. Her pati...

Speeding the search for elusive chromosomal errors

...omosomes," added Dr. Shaikh. "Now we have a better tool for finding the abnormal gene or genes that give rise to a disorder." The research is published in the May 2006 issue of Human Mutation. For many of these rare disorders caused by small errors in chromosomes, improved diagnosis does not mean that ph...

UCSD researchers develop 'smart petri dish'

... the potential of the technique as a complementary tool for cell viability studies." In addition, they add, their method "is noninvasive and can be performed in real time, representing a significant advantage compared to other techniques for in vitro monitoring of cell morphology," that is, for monitoring...

Study shows frogs can play key role in stem cell research

...ticipate that it will become an important research tool in their quest to understand and, ultimately, treat disease using stem cells. The results of their study are published in the current edition of the journal Development. The key protein in humans, called Oct4, which governs the process of unlimited ...

Gene screen for breast cancer better than pathologist's 'eye'

First-ever genomic test predicts which lung cancer patients need chemotherapy to live

...icine and lead author of the study. "We now have a tool that can be used to move these high-risk patients from the 'no chemotherapy' group into the aggressive treatment group." The researchers will publish their findings in the Aug. 10, 2006, issue of the New England Journal of Medicine. The research wa...

Even when faint, ovary scent draws sperm cells

...emotaxis could potentially be used as a diagnostic tool to determine sperm quality or as a therapeutic procedure in male infertility," Jacobson said. The project is a collaboration between research groups led by Jacobson and IUB Distinguished Professor of Chemistry Milos V. Novotny. Their work led to th...

Cells use mix-and-match approach to tailor regulation of genes

New light microscope sharpens scientists' focus

...ssible under physiological conditions. It was a tool developed in a biology lab that ultimately inspired the two physicists plan to build a better microscope. "In the world of biology there is a new generation of fluorescent proteins that you can switch on at will with a little bit of violet light," He...

Primates take weather into account when searching for fruits

... use their stored knowledge of recent weather as a tool for guiding their foraging behavior when searching for ripening fruit. The work, which potentially informs our understanding of how cognitive skills developed in humans and other primates, is reported by Karline Janmaat, Richard Byrne, and Klaus Zube...

'Signature' of chromosome instability predicts cancer outcomes

...m's work could also form the basis of a diagnostic tool that could be used in the clinic. The human genome is at constant risk for mutations due to environmental insults, errors in gene replication, and other factors that can cause chromosomes to break and bits of DNA to be lost, duplicated or reshuffle...

...nse." But the TonB-Tol "cross talk" does provide a tool for mixing and matching parts of the systems and asking what's important and what isn't. "To begin understanding how proteins talk, we first made random mutations--we broke things and then asked what happened," Larsen says. "That strategy worked we...
