Calcium transfer impacts fuel mechanism for normal cell metabolism

University of Pennsylvania School of Medicine researchers have described a previously unknown biological mechanism in cells that prevents them from cannibalizing themselves for fuel. The mechanism involves the fuel used by cells under normal conditions and relies on an ongoing transfer of calcium between two cell components via an ion channel. Without this transfer, cells start consuming themselves as a way of to get enough energy.

Scientists develop carbon based nanoscale to detect single DNA molecules

Researchers at the University of Pennsylvania have developed a new, carbon-based nanoscale platform to electrically detect single DNA molecules.Using electric fields, the tiny DNA strands are pushed through nanoscale-sized, atomically thin pores in a graphene nanopore platform that ultimately may be important for fast electronic sequencing of the four chemical bases of DNA based on their unique electrical signature.The pores, burned into graphene membranes using electron beam technology, provide Penn physicists with electronic measurements of the translocation of DNA.

ACS to hold symposium on Deepwater Horizon oil spill

The American Chemical Society (ACS) will hold a special day-long symposium on the Deepwater Horizon oil spill on Tuesday, Aug. 24 during its National Meeting & Exposition here. The symposium, which includes almost a dozen experts, will examine topics ranging from the spill's effects on marine life to its effects on the safety of seafood. It will take place from 8 a.m. to 4 p.m. in Room 210C of the Boston Convention and Exhibition Center, followed by an open-discussion session from 4:30 p.m. to 6 p.m.

New development in flu prevention & treatment

In a groundbreaking development, scientists at the Australian National University in Canberra have found the key to the mutation of the flu virus. This may allow the manufacturing of a life-long vaccine stopping the need for repeated vaccinations. The scientists reveal that they have found a protein in the virus that changes or mutates in order to develop resistance in the virus.

New REMESENSE TOOTH DESENSITIZER for treating tooth hypersensitivity

Nuline Pharmaceuticals, LLC announces the introduction of REMESENSE (dipotassium oxalate 3%) TOOTH DESENSITIZER, an Rx Class II medical device now available in the U.S. REMESENSE was introduced globally in 2008. It is presently sold in 16 countries, ranging from England and the European Union to Asia and Africa. Nuline expects to launch REMESENSE in Canada and other countries later this year or by early 2011.

Research provides better understanding of drugs used to treat, prevent cardiovascular disease

Using chemical labeling and mass spectrometry-based techniques, Mark Chance, PhD, director of the Case Western Reserve University School of Medicine Center for Proteomics and Bioinformatics and professor of physiology and biophysics; Sayan Gupta, PhD, instructor at the Case Center for Proteomics and Bioinformatics; and a research team from the University of Oxford, for the first time, were able to take a high resolution picture of the open state of a K+ channel, allowing them to comparatively analyze gating mechanisms important to heart function and nerve signaling - in addition these techniques have already permitted Case Western investigators to gain a deeper understanding of G-protein coupled receptors.

VA addresses health concerns including possible HIV exposure and Veterans' general poor health

"The Democratic chairman of the House Veterans Affairs Committee lambasted the Obama administration over its handling of an incident at a St. Louis VA center in which more than 1,800 veterans were told they may have been exposed to HIV. ... The Department of Veterans Affairs last month sent a letter to 1,812 patients informing them that could have been exposed to HIV and other deadly viruses because of dental equipment that was insufficiently sterilized over a period of 13 months."

New method to synthesize drug candidates for testing

Some drugs may be more effective the longer they last inside the body. To prevent such drugs from being broken down too rapidly, pharmaceutical manufacturers often attach a fluorine-containing structure called a trifluoromethyl group. However, the processes now used require harsh reaction conditions or only work in a small number of cases, limiting their usefulness for synthesizing new drug candidates for testing.

Study explains how vesicular release of neurotransmitters is impaired

Effective brain function depends on the efficient signaling from one neuron to the next, a lightning-fast process that depends on a quick release of neurotransmitters at synapses. Exposure to lead during early childhood and even later in life has long been known to affect the release of these critical neurotransmitters. However, the precise mechanism by which lead ions (Pb2+) impair this process has remained unknown.
