Platelet refrigeration method may ease shortages for transfusions, researchers report in Science

...must currently be stored at room temperature for a limit of five days. After this period, the platelets must be thrown away, because they no longer function properly and their risk of bacterial contamination increases sharply. Shortages in donated platelet supplies can have serious consequences, because pa...

Study at TSRI links dozens of proteins to several rare muscle and nerve degeneration diseases

...t they were able to apply computational methods to limit the final list of new human nuclear membrane proteins to 62. The scientists then took eight of these proteins at random and demonstrated that they all indeed targeted to the nuclear membrane. The new nuclear membrane proteins identified in this...

Washington University in St. Louis, Monsanto Co., awarded crop protection patent

... virus infection by using chemical insecticides to limit spread of viruses. The "coat-protein mediated resistance" technology, like other disease resistance genes, can substantially reduce farmers' reliance on chemical insecticides. Therefore, this technology has helped solve an otherwise unsolvable prob...

Enhancing the nutritional value of soybeans

...ere the high cost of synthetic second-tier AAs may limit their use. Anthranilate synthase (AS) catalyzes one of the key steps in the biosynthetic pathway for tryptophan production in plants. To increase tryptophan content in soybean seeds, a variant of the maize AS gene that is insensitive to tryptophan i...

Straight talk: Adult and embryonic stem cells and the future of research

...it," says Civin. Criticizing policies that would limit study to only stem cells from "adult" tissue, or from embryonic tissue, Civin says the key to making progress scientifically, which eventually improves medicine, is to approach a question from a number of angles. Limiting the approaches slows discove...

Cold-climate creatures may be the ultimate survivors of global warming, study finds

Strategy to treat AIDS patients in Africa with less drug, reduced toxicity set for clinical test

...the high cost of providing drugs for studies would limit the agency's overall capacity for supporting international AIDS research. Also, the agency and researchers alike agree that an important ethical consideration is to address this issue of providing continuing access after a study to the live-saving dr...

World first for Swedish researchers mice born from transplanted wombs

...s demonstrates is that in mice, at least, the time limit for removing a uterus and transplanting it is between 24 and 48 hours," said Professor Brnnstrm. Another major problem in transplantation is organ rejection. This differs between organs depending on the extent of blood vessels, the specific type of c...

New center for preparation and distribution of adult stem cells

"This center, with the emphasis on quality control and standardized methods, will move this promising research forward." Adult stem cells h...

Scientists identify genetic link between cancer and aging

...ent with the hypothesis that genetic programs that limit organismal aging may, at the cellular level, promote tumor development, thus constituting a double sword. On the positive side, we hope that our study will provide a new therapeutic target able to trigger tumor cells into senescence." Dr. Grandor...

UGA scientists discover gene that maintains genome integrity by limiting DNA replication

...ct it from unrestrained replication. A failure to limit DNA replication leads to the indiscriminate expansion of genomic DNA, which has catastrophic consequences for the survival of the organism. The identification of CUL-4 as a major regulator of DNA replication levels will likely lead to investigations ...

Media seminar on cardiovascular medicine

In terms of total funding and number of researchers, the CVC is one of the top cardiovascular research groups in the count...

Insulin study sheds light on physics of crystal growth

... While Vekilov's research has focused on trying to limit step bunching in protein crystals, he says understanding the physics of how step bunching occurs - or doesn't occur in the case of insulin - can help scientists by increasing their knowledge of crystal systems and improving crystal-growing methods. F...

Plants and people share a molecular signaling system, researchers discover

The researchers found that the enzymes product, S1P, is involved in both inhibiting the opening of the plant's pores and promoting their closure. In addition, Assmann and her team discovered that, in plants as...
