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

...protein from among a billion candidates that could perform the unusual feat of attaching to polypyrrole, a synthetic polymer (plastic) that conducts electricity and has shown promise in biomedical applications. When the protein piece, or peptide, was linked to a smaller protein piece that human cells like to...

Researchers make headway in mystery of migraines

...30% of the energy produced by the cell in order to perform this vital cellular process. Of particular interest in this study is that some mutations cause migraines by reducing sodium pump efficiency--akin to reducing the power supply. "This is the first time that a genetic mutation of the sodium pump has be...

Brown-Harvard team solves mobile DNA's surgical sleight-of-hand

... inside an organism, or into another organism, and perform a sort of grafting surgery that allows it to insert its chromosome into a chromosome of the target cell. The process is important because mobile DNA can carry genes that cause drug resistance or transmit viruses that cause disease or tumors that resu...

To translate touch, the brain can quickly rearrange its sense of the body

...uch different kinds of information, the brain must perform a constant juggling act in order to make sense of the body and the world. In the new study, the research team used a method called tendon vibration to induce a distortion of healthy volunteers' sense of their own bodies. When the biceps tendon of th...

Female volunteers prepare for a second 'bedrest'

...on and movement). While the control group did not perform any particular activity, an 'exercise' group were put through their paces in regular exercise sessions. In another group, daily meals were accompanied by a dietary supplement (certain amino acids which form the basis of proteins). Volunteers needed ...

Most common lung cancers may begin in newly discovered cells

...hem back into the mouse and show in vivo that they perform as stem cells," Bender Kim said. "We don't have an assay for that yet." With hematopoietic stem cells, for example, scientists can inject the stem cells into the bone marrow of an irradiated mouse and replace the entire blood system, the basis of bo...

Micro-molecule plays big role in birth defects

...an cellular debris, these short strands of RNA may perform a vital role in healthy development by strategically turning off gene activity. By genetically modifying mice, scientists with the UF Genetics Institute were able to get the first-ever picture of how limbs would develop in a vertebrate without the h...

Stem Cells Found In Cerebellum; Possible Cell of Origin for Childhood Brain Tumors

... cells as well as a host of specialized cells that perform designated tasks in a particular tissue or organ. But when stem cells become activated at the wrong time or place, rapid proliferation can give rise to cancer, said Wechsler-Reya. The researchers discovered the stem cells while studying the developm...

Cultural norms not unique to human societies

...ees within their groups were allowed to watch them perform the new skill over a seven-day period before all group members were allowed to use the tool. According to the researchers, group members gathered around the local expert, watched attentively and proved successful when allowed to try the task on their...

Beyond genes: Lipid helps cell wall protein fold into proper shape

...tinctly superior and who are likely to continue to perform in an outstanding manner, the NIGMS notes. MERIT (Method to Extend Research in Time) status essentially gives Dowhan a 10-year renewal to 2015 on his longstanding NIGMS grant "Structure and Function of Membrane Proteins" by providing back-to-back fi...

Old drug, new tricks: Prospects for slashing the impact of malaria

... - or perhaps the old drug teaching us that it can perform tricks that we never suspected it could." The four-year trial is being conducted in PNG for a number of reasons. First, PNG is a relatively confined area with a high concentration of all four types of global malaria ?unlike Africa, where one type p...

Researchers create functioning artificial proteins using nature's rules

...specific three-dimensional shapes help proteins to perform their biological functions. For decades, scientists have known that the sequence of amino acids that make up a protein determines the protein's structure and its function. What has not been known is what information contained within that sequence p...

Nanoscale method for investigating living systems

...al membranes, the team believes quantum dots could perform similarly in other excitable cells such as neurons and muscles, and looks forward to understanding how the dots behave in vivo in excitable cells. The researchers will look next into properties that cause the artificial pores to open and close. ...

MSKCC researchers uncover structure of key protein complex in cells

...es have remarkably similar structures, though they perform different tasks in cells. Ubiquitin acts as a chemical tattoo that marks damaged or obsolete proteins for destruction by a protein complex in the cell called the proteasome. Cancer researchers became particularly interested in ubiquitin with the dis...

Fish and chips: A fast track to understanding blood development

...For example, researchers at the University already perform umbilical cord blood transplants to treat disease. But there are often not enough blood stem cells harvested from a single collection of umbilical cord blood to effectively treat adults and older children. This research provides insight into understa...

Firefly protein lets researchers monitor molecule linked to cancer
