Cleaner water, more efficient electricity among UH chemical research

...ranging from bacteria removal in water and quantum shuttles in electricity to defining career moments, at the 228th National Meeting of the American Chemical Society, Aug. 22 to 26 in Philadelphia. Founded in 1876, the American Chemical Society (ACS) is a nonprofit, scientific, educational organization. Ch...

RNA could form building blocks for nanomachines

...s could be built from RNA, the same substance that shuttles messages around a cell's nucleus, reports a Purdue University research group. By encouraging ribonucleic acid (RNA) molecules to self-assemble into 3-D shapes resembling spirals, triangles, rods and hairpins, the group has found what could be a me...

New protein provides clue to diabetes

...are glucose transporters, a class of proteins that shuttles glucose molecules through the membrane and into the body of the cell. The first glucose transporter was discovered in 1985 in Lodish's lab. Several others, including GLUT4, have been discovered since then. While most glucose transporters reside at th...

Bleeding disorder tied to defect in cellular transport mechanism

...NN ARBOR, Mich.---Defects in a cargo receptor that shuttles proteins from one place to another within the cell lie at the root of a rare bleeding disorder, according to a study published in the June issue of the journal Nature Genetics. An international research team led by David Ginsburg of the University of...

Free shuttles can close the grocery gap

...pportunities. Some of our members already utilize shuttles in their businesses and have found them to be successful and profitable, said Peter Larkin, president of the California Grocers Association. This study provides further information and guidance for those who are interested in expanding the concept in...

Artificial cell gets light-powered nanopump for calcium ions

... has developed a light-powered molecular pump that shuttles calcium ions through a phospholipid membrane calcium ion pumping that resembles various key cellular activities in living organisms, but engineered to be powered by light through specially designed molecules. The research is reported in the November...

Clock cues: Cellular sensing, metabolism research wins Amersham Biosciences and Science Prize

...e brain contains a busy transportation system that shuttles neurotransmitters and other proteins between neurons using a variety of molecular motors, making the biochemical connections that underlie memory and learning. But are these motors "equal opportunity" carriers, or do they recognize and carry specifi...

Hidden toxin gene in chlamydia linked to chronic illnesses

...d toxin-encoding RNA, a type of DNA photocopy that shuttles its genetic instructions to the cell's protein-making machinery. The researchers also showed that infected cells contain a protein resembling toxin B, suggesting the cells deciphered the RNA's instructions. "Finding the toxin would have been nearly...

Colorado set to fly biomedical experiments on September shuttle flight

...serve payloads have been launched on 17 NASA space shuttles since 1991, have twice ridden on Russias Mir Space Station, and are expected to have a permanent presence on the International Space Station beginning in 2001. BioServe also will be using the Atlantis flight for a follow-up experiment from a prev...

UH lab identifies first gene mutations in blood vessel disease

... codes for production of an ABC transporter, which shuttles proteins across cell membranes. The gene is also of interest because it has been associated with drug resistance that occurs when drug compounds are not carried across the cell membrane into the cell. ABC transporters do not typically carry calcium, ...

Understanding key protein in Fragile X syndrome

...onucleoprotein particle). They also know that FMRP shuttles between the cell's nucleus and cytoplasm, and that it visits ribosomes, where the genetic code for building proteins is translated. From all this evidence, they speculated that FMRP must somehow be involved in the translation process. To understand ...

University of Pittsburgh study suggests herpes-delivered gene could provide long-term, systemic therapy for peripheral neuropathy

...first time have shown that a modified herpes virus shuttles a therapeutic genenot only to neurons that it typically enters, but also to non-neuronal cells andin turn provides an important long-term source of protein called nerve growthfactor (NGF). Furthermore, they found that the newly manufactured NGF ente...

Scientists Bridge Gap In Cell Communication

... the signal switches genes on or off. This protein shuttles from the inner surface of the cell membrane right to the DNA, in one fell swoop." The discovery, Laughon emphasized, will have no immediate medical application, but may lead to the development of new genetic-based treatments for disease. It...
