Discovery of 'master switch' for the communication process between chloroplast and nuclei of plants

...nd Molecular Biology, has determined that multiple distress signals in plants converge on a single pathway, which then channels the information to the nucleus. The study was part of a collaborative effort led by Joanne Chory, professor and director of the Plant Biology Laboratory at the Salk Institute for Bio...

New culture method for hepatitis C virus uses primary hepatocytes and patient serum

...ponded to viral replication by displaying signs of distress and cell death and by expressing interferon-beta, a cellular antiviral, in an effort to control the infection. This culture system provides a breakthrough in studying HCV replication in nontransformed hepatocytes, the natural target of the virus....

New study: Preterm birth causes one-third of all infant deaths

...death and combined conditions, such as respiratory distress syndrome, which frequently occur in premature babies. This new method doubled the percentage of infant deaths caused by premature birth to 34.3 percent. More than 95 percent of those deaths were of infants who were born at less than 32 weeks gestat...

Why don't all moles progress to melanoma?

...ill the cell. To prevent this, the ER sends out distress signals to activate what scientists call the unfolded protein response (UPR). This slows the protein production process and gets rid of excess incoming amino acids, giving the ER a chance to catch up. If that doesn't work, the UPR causes the cell to ...

New brain-chemistry differences found in depressed women

... of messages related to pain, stress and emotional distress between the body and the brain. They have been called the body's "natural painkillers." The drug is modified to allow it to be "seen" by the PET scanner, so that the researchers can create maps of the specific brain areas where the natural mu-opioids...

SARS: No evidence that any of the treatments worked

Key to acute lung injury lies in Ang2 protein

...te lung injury and in babies born with respiratory distress syndrome who either went on to develop bronchopulmonary dysplasia or died. "Mice without Ang2 seemed to be protected against hyperoxia," said first author Vineet Bhandari, M.D., assistant professor of pediatrics at Yale School of Medicine. "This p...

Pleasure and pain: Study shows brain's 'pleasure chemical' is involved in response to pain too

... more a person rated the pain as causing emotional distress and fear, the more dopamine was released in the area known as the nucleus accumbens ?the same region implicated in drug addiction. That effect persisted even after the researchers controlled for the negative emotional effects caused by the actual...

Can you hear me now? Scientists find previously unknown receptors on adult stem cells

...MRF researcher. "And when stem cells receive these distress signals, they spring to action, creating cells the body most needs early in life-threatening situations." This messaging system normally serves as an effective means of quickly replacing cells that are damaged or killed while keeping us healthy. But...

Mayo Clinic collaboration discovers protein amplifies DNA injury signals

...Now that they understand MDC1's role in amplifying distress calls from injured DNA to cue the repair process, the Mayo researchers are investigating another system that appears to play a similar role in the cell. "If we can understand all the pathways involved in signaling the DNA repair process, we may be ab...
