Scientists stop autoimmune disease without shutting off immune system

...n cells together. They develop severe blisters and raw sores as the top layer of their skin falls apart, leaving them extremely vulnerable to infection. The development of drugs that completely suppress the immune system offered a lifeline to patients with pemphigus vulgaris (PV) and other autoimmune ...

Finding a better way to make biodiesel

...ogies that would effectively make biodiesel out of raw materials such as used restaurant oils and animal fats ?materials that are much cheaper than soy oil, but also contain free fatty acids that can't be converted to biodiesel by current production methods. Lin has developed a nanotechnology that accu...

Heparin prepared synthetically could replace animal-derived drug

...s will enable us to effectively replace a variable raw material ?heparin derived from processed animal organs ?with a synthetic material ?synthetic heparin ?and have the same therapeutic result." Research in Linhardt's group at the Center for Biotechnology and Interdisciplinary Studies at Rensselaer fo...

Scientists force viruses to evolve as better delivery vehicles for gene therapy

...e the target of directed evolution. To provide the raw material for evolution - the genetic variation from which nature selects the best-adapted organism - the researchers created mutant viruses by introducing small variations in the genes through an error-prone polymerase chain reaction (PCR) coupled wi...

Waking a sleeping virus

...ng the information to be read and transformed into raw materials to make new viruses. "A good strategy in fighting viruses is to block the activation of viral genes," says Patrice Morand, a physician at the University hospital and the IVMS. "The drugs we currently use against EBV work that way. The pro...

Expert dispels bird flu paranoia

... local government biosecurity officer. Don't eat raw or undercooked chicken. Don't use untreated water, use clean town water or bore water. "Consumers of poultry meat and egg products should not be concerned as the risk of infection from eating poultry products is extremely low," Dr Doneley said....

Mining biotech's data mother lode

...l and biotech companies produce vast quantities of raw data on the problems that interests them. Microarrays process thousands of samples to discover what genes are over expressing. These over-expressing genes ?numbering sometimes in their thousands, too ?create proteins. The researchers then need to dis...

Restaurant seafood prices since 1850s help plot marine harvests through history

... slightly fallen. 5) Inflation-adjusted prices of raw oysters. Raw oysters have been popular on restaurant menus for over 150 years. The inflation adjusted prices from New York and Massachusetts restaurant menus very closely track the inflation rate from the 1850's to the 1950's, after which they double...

Many cats unaffected by catnip, C&EN reports

...tnip (Nepeta cataria), available in pet shops as a raw herb or essential oil, says McDaniel. Nepetalactone is one of several compounds known to set off the characteristic set of behaviors associated with exposure to catnip. These behaviors generally start with sniffing, licking and chewing, followed by h...

Retina adapts to seek the unexpected, ignore the commonplace

... the system seeks to extract from the onslaught of raw visual information the few bits of data that are relevant to behavior. This entails the discarding of signals that are less useful, and dynamic retinal adaptation provides a means of stripping from the visual stream predictable and therefore less new...

Use of high hydrostatic pressure to inactivate Hepatitis A virus in oysters studied

...se reasons, high hydrostatic pressure treatment of raw oysters is especially appealing to oyster processors and distributors, as well as public health officials. HPP makes it possible to eradicate or inactivate pathogens while still delivering a 'raw' product to the consumer. The study will benefit proc...
