Technique makes it easier to see mouse embryo in all its glory

...stration) mandate that chemical and drug companies perform tests of reproductive safety, but how complete are these studies? Historically, these studies have been semi-quantitative or subjective. However, microCT-based Virtual Histology allows chemical and drug companies to conduct these studies in a much mo...

Picking apart how neurons learn

... eye movements with head movements, allowing us to perform activities such as reading in a moving automobile. "We've long known that LTD underlies responses like the vestibulo-ocular reflex. This study gets at the heart of how LTD occurs, specifically how PICK1 controls the Purkinje cell's response to the s...

For one Stanford doctor, the beat goes on during open-heart surgery

...r sews on new vessels. It's easier for surgeons to perform because they have a stable target. The heart is not moving. In beating-heart surgeries - currently used in about 22 percent of U.S. bypass procedures - a surgeon's ability to stitch vessels onto a moving, blood-filled heart replaces the need for the...

GlycoFi announces the first production of antibodies with human glycosylation in yeast

... last five years engineering yeast cell lines that perform human glycosylation, which now allows us to glycosylate proteins with unprecedented control and uniformity." In the study described in Nature Biotechnology, the researchers used several glyco-engineered yeast cell lines to produce a library of glyco...

Ticks, flukes, and genomics: Emerging pathogens revealed

...tionized the types of experiments [scientists] can perform to understand these diseases," says microbiologist Yasuko Rikihisa of OSU's College of Veterinary Medicine. "Already, at least four labs are performing, or planning to perform, whole genome DNA microarray analysis and proteomic analysis of these bact...

Stem cell study for patients with heart attack damage seeks to regenerate heart muscle

...eded." Adult stem cells are designed by nature to perform tissue repair in a mature adult. It is believed that these cells can be used in patients unrelated to the donor, without rejection, eliminating the need for donor matching and recipient immune suppression. Once transplanted, the cells promote healing...

Earth Rx: A microbial biotechnology prescription for global environmental health

...possible, particularly having different microbe to perform the same role. "It usually isn't just one organism, a superbug or magic bullet," says Rittmann. "Instead, the best results require a community of microorganisms." Rittmann is motivated by the huge benefits that environmental biotechnology and micro...

Curry and cauliflower could halt prostate cancer

... we knew little about how PEITC and curcumin would perform in live animals, especially on prostate cancer," Kong said. "So we undertook this study to evaluate how effective PEITC and curcumin might be ?individually and in combination ?to prevent and possibly treat prostate cancer." The researchers injected ...

Watching the brain switch off 'self'

...ures or listen to the same musical phrases, but to perform two different kinds of processing on them. To explore sensory processing, the researchers asked the subjects to use buttons to classify the images as animal/non-animal, or the musical passages as trumpet/non-trumpet. And to study introspection, the r...

Tool developed to silence genes in specific tissues using RNAi

... to be decoded by ribosomes into the proteins that perform all the work of the cell. RNAi, therefore, recognizes the double strand of viral RNA as different, and sets in motion cell machinery that destroys the invading RNA. This involves cutting up the double-stranded RNA, separating it into single strands, ...

Researchers reveal lung's unique innate immune system

...ibition by TGFb for brief period of time, in order perform their immune task. This is accomplished through regulation of TGFb activity by a set of cell surface receptors, proteins called integrins. This regulation allows the alveolar macrophages to take on their "killer" function ?the ability of macrophage...

USC, Rice to develop bacteria-powered fuel cells

...k," said Lüttge. "The computer simulations help us perform better experiments, and the laboratory tests help us design better simulation, and the overall combination saves time and money." In addition to the computational modeling, Lüttge will contribute his experimental skills in an imaging technique calle...

UF researchers develop ways to keep the bloom on the rose

...cipates that floral sales will increase if flowers perform better by withstanding the test of time. "It is already proven that flowers are the most popular gift to receive, that they consistently increase a sense of individual well-being, and are even capable of increasing creative thought and output in wo...

Australian first to save sight

...extending the time between donation and needing to perform the transplant. Thanks to the new facilities, LCDS can now store corneas at human body temperature levels (34C) for up to a whole month. Previously, corneas were held at low temperatures and had to be transplanted within one week of the donation. D...

Two NIH initiatives launch intensive efforts to find roots of common diseases

... proposed federal funding level will enable GEI to perform genetic analysis ?or genotyping - studies for several dozen common diseases. The exact diseases to be studied will be determined by peer review. An initial survey of existing NIH-supported clinical studies identified more than 100 with sufficient num...

Morning grogginess more debilitating than sleep deprivation, according to CU-Boulder study

...ransportation workers who are often called upon to perform critical tasks immediately after waking, since cognitive deficiencies following 24 hours of sleep deprivation have previously been shown to be comparable to the effects of alcohol intoxication, he said. The study appears in the Jan. 11 issue of the ...

A new way of looking at molecular motors

...k will help scientists ask the right questions and perform the right kind of experiments on myosins," Foth said. "In the long term, that could lead to new drug targets being discovered more quickly." Molecular motors run on tracks, like trains, using chemical reactions that involve the chemical compound ad...

MIT research holds promise for Huntington's treatment

...of cellular structures known as proteasomes, which perform a "trash can" function for the cell -- disposing of cellular proteins that are misfolded or no longer needed, said Bodner. Without a functional proteasome, those cellular proteins accumulate, poisoning brain cells and impairing patients' motor and c...

Virginia Bioinformatics Institutes launches microbial database

...ty annotation features, toolkits, and resources to perform complex queries of biological information. The project's researchers created a browser, which makes it easy for users to view the genome sequence data and connect to detailed annotation pages for each sequence. The community annotation interface is a...
