Engineers improve plastic's potential for use in implants by linking it to biological material

...ething contributed by the other amino acids in T59 influenced its 3-dimensional shape in a way that augmented its plastic preference. "This aspartic acid is just one piece of the puzzle," Sanghvi said. "There are still more pieces to put together." The researchers also evaluated how well T59 clings to polypyrr...

Changing ecosystems throw scientists mega-challenges

...environment system. "All human natural systems are influenced by the distribution, abundance, quality and accessibility of water," it says. With continued human population growth and the uncertain impacts of of environmental change, the report states, ensuring an adequate quantity and quality of freshwater for ...

At long last, scientists figure out how plants grow

... that the binding of TIR1 to auxin is not directly influenced by other plant cell proteins. Auxins influence a wide variety of plant processes. For example, they are the hormones that cause roots to grow downward and flowers to track the moving sun. Auxins also stop the growth of lateral branches. Since auxins...

Biomarkers isolated from saliva successfully predict oral and breast cancer

...salivary nucleic acids or protein markers might be influenced by eating, drinking, smoking, diet or oral hygiene," said Wong. "So our goal is to provide the optimized and standardized protocol to assure consistent results." The studies are supported by grants from the U.S. Public Health Service (National Insti...

White Blood Cell 'Waste Disposal' System Plays Critical Regulatory Role

...tigated whether ingestion of apoptotic neutrophils influenced IL-23 production by phagocytes. The researchers observed that the amount of IL-23 produced by phagocytes was reduced when phagocytes actively ingested apoptotic neutrophils. Interestingly, mice with abnormal neutrophils that lacked the ability to mi...

Harmful chemicals may reprogram gene response to estrogen

...not the first study to suggest that cancer risk is influenced by both genetic and environmental factors. A 2003 study of Jewish women born with a defect in BRCA1, the gene that is linked to inherited forms of breast and ovarian cancer, showed that those women born before 1940 had a much lower risk of developing...

New drug shows promise as powerful anticancer agent

...how that, in contrast to tumor cells, they are not influenced by ON01910. The authors suggest that because ON01910 is highly effective in combination with other chemotherapies and appears to be nontoxic, it may be beneficial for treatment of some advanced cancers that are resistant to conventional therapies. "...

Children's taste sensitivity and food choices influenced by taste gene

...y related to genes, age, or both. Such differences influenced interactions between mothers and children: mothers insensitive to bitter taste perceived bitter-sensitive children as being more emotional than bitter-insensitive children. "This knowledge may bring relief to parents who learn that their children rej...

Study of genomic DNA leads to new advances in cancer diagnostics

...CM), or the microenvironment surrounding the cell, influenced whether the cell's chromatin was sensitive or resistant to Alu I. The group also implicated the cell's cytoskeleton, the internal scaffolding that gives the cell its shape, in this process. Changes to the ECM and cytoskeleton are critical to migratio...

Weizmann Institute scientists develop a new approach for directing treatment to metastasized prostate cancer in the bones.

...pattern occurred.Since cell survival in general is influenced by an “anti-death?genecalled Bcl2, Fisher’s team analyzed mice lacking this gene. In adramatic fashion, the mice lost their melanocyte stem cells shortlyafter birth and quickly went gray. It may be that people who grayprematurely have mutations that ...

Cytoplasm affects the number of vertebrae in carp-goldfish clones

... not the genetic code of the transplanted nucleus, influenced this aspect of the skeleton as the cloned fish developed. They speculate that a so-called "segmentation clock" early in embryonic development is controlled by the egg cytoplasm. Thus the egg cytoplasm of the recipient goldfish directs segmentation o...

UCLA Study Shows One-Third of Drug Ads in Medical Journals Do Not Contain References Supporting Medical Claims

...es have shown that physicians' drug prescribing is influenced by pharmaceutical ads. We wanted to see what documents were being used to substantiate the claims and how accessible these were to physicians who may want to verify the research findings," said lead author Dr. Richelle Cooper, assistant clinical prof...
