IMF Launches World’s First DNA Database for Myeloma Patients

...ology graduate student in Arts & Sciences, has performed studies on mosquitofish (guppy-like fish, about an inch long) and found that female mosquitofish spend 80 percent more time with males who have a large gonopodium. "A male with a larger gonopodium has a higher chance of mating, but in a predator env...

This extensive study, performed under the direction of Dr. Shigeyuki Wakitani, who is an assistant professor at the Department of Orthopedic Surgery, Shinshu University School of Medicine, examined joint tissue from patients who underwent total knee replacement for rheumatoid arthr...

Blink, and the brain misses it

... when the volunteers blinked. The researchers then performed a type of brain scan known as functional magnetic resonance imaging and could thus measure whether the act of blinking--independently of any change in light normally caused by eyelid closure--would influence the level of light-activated brain activit...

Researchers develop new method for facile identification of proteins in bacterial cells

...roverbial needle in the haystack; this task can be performed much faster and more economically if you have more needles--and that's exactly what our method is based on," explained Dr. Halden. "Instead of spending a lot of time and resources on eliminating the background noise to find the signal, our method inc...

Drug Offers Alternative to Surgical Treatment After Miscarriage

... surgical procedure. Moreover, because it could be performed on an out-patient basis, the misoprostol treatment was less expensive and could provide women more privacy and convenience than vacuum aspiration. Roughly one in four women experience miscarriage, so the availability of a non-surgical treatment may p...

Identification of specific genes predicts which patients will respond to Hepatitis C treatment

...cation for liver transplants. Liver biopsies were performed on the 31 chronic HCV patients before treatment, and were compared to 20 biopsies from healthy, uninfected livers. 16 patients did not respond to subsequent treatment, while 15 did; both groups were well matched with respect to age, HCV viral load (n...

New clue to cocaine addicts' quirky behavior

...ong-term potentiation (LTP). The researchers also performed behavioral studies on the cocaine-sensitized rats, to explore the behavioral effects of this disruption. In these studies, they placed the rats in a plus-shaped maze. The rats were taught that in response to a visual cue they should turn left or righ...

Microreactor efficiently regenerates cofactors for biocatalysis

...ation." Using their microreactor, the researchers performed a model biocatalytic process by converting an achiral substrate (pyruvate) into a chiral product (L-lactate), using lactate dehydrogenase as the enzyme. While further research is needed to improve the performance of individual microreactors, the pre...

Researchers devise new technique for creating human stem cells

...should be further explored." The researchers also performed fusion experiments using pelvic bone cells as the somatic cells and a different human embryonic cell line, to demonstrate that their technique was not restricted to one adult cell type or embryonic cell line. In both cases, the researchers observed...

Ants win a waxy race

...r contains two claws and an adhesive pad. Bruening performed experiments with ants running along glass and wax rod, clipping off their claws or pads to assess the essence of these components. She observed that, as it approaches a waxy surface, the ants use these claws to interlock to the surface. However, on ...
