Washington, DC, USA. General anesthesia puts patients into unconscious sleep so they do not feel surgical pain, but researchers say it can increase their discomfort once they wake up.
The findings provide scientific confirmation for an increasing number of anecdotal observations in clinics.
In the Proceedings of the National Academy of Sciences (PNAS), scientists report that "noxious" anesthesia drugs — which includes most of these general anesthetics - activate and then sensitize specific receptors on neurons in the peripheral nervous system. These are the sensory nerves in the inflammation and pain pathway that are not affected by general anesthesia drugs that target the central nervous system – the brain and the spinal cord.

New Haven and Greenwich, CT, USA. Human beings naturally wonder how others might perceive our appearance — and to what extent that might imply estimates by others of the the state of our feelings. Do the indicators suggest we are withdrawn or hostile (e.g., do we look tired or angry)? Our comfort in social situations might well depend on the answer to that question. Recent research suggests that looking tired or angry may have more to do with facial aesthetics than how we actually feel.

Montreal, Quebec, CAN. Researchers performed the world’s first totally automated administration of an anesthetic. Nicknamed “McSleepy,” the new system administers drugs for general anesthesia and monitors their separate effects completely automatically, with no manual intervention. The anesthetic technique was used on a patient who underwent a partial nephrectomy, a procedure that removes a kidney tumor while leaving the non-cancerous part of the kidney intact, over a period of three hours and 30 minutes.

The annual survey shows that the average age for patients receiving invasive cosmetic surgery has increased since 2002. Through late 2007, the mean age of patients seeking the top ten most performed invasive procedures has increased by two years.
 “Cosmetic surgeons are seeing anywhere between a one to three year increase in our patient’s age,” said Dr. Steven Hopping, MD, AACS President. “It appears that as baby boomers grow older, so does our clientele.”
The aging population and the baby boomers are likely to be the dr

Bristol, UK. New research shows that by suppressing one of the genes that normally switches on in wound cells, the wounds can heal faster and with reduced scarring. When skin is damaged, whether by accident or surgery, a blood clot forms and cells underneath the wound start to repair the damage, leading to scarring. Scientists and medical care practitioners have worked to alleviate this problem, but problems remain, not just for wound victims but also for people with organ tissue damage through illness or abdominal surgery.
Tissue damage triggers an inflammatory response by white cells to protect skin from infection by killing microbes. The same white cells guide the production of layers of collagen. These laye

Finding Our Way
The Human Genome Project (HGP). The HGP identified all of the genes in the human genome and mapped their individual sequencing. Basic work began in 1990 and reached completion in 2005, sparking continuous refinements and new projects. Though the HGP is finished, data analyses will continue for many years.
A genome is all the DNA in an organism, including its genes and other materials. Genes carry information for making all the proteins required by all organisms. These proteins determine, among other things, how the organism looks, how well its body metabolizes food or fights infection, and to an extent even how it behaves.
DNA is made up of four similar chemicals (called bases and abbreviated A, T, C, and G) that are repeated millions or billions of times throughout a genome. The human genome, for example, has 3 billion pairs of bases. The particular order of As, Ts, Cs, and Gs is extremely important.
The order underlies all of life's diversity, even dictating whether an organism is human or another species such as yeast, rice, or fruit fly, all of which have their own genomes and are themselves the focus of genome projects. Because all organisms are related through similarities in DNA sequences, insights gained from nonhuman genomes often lead to new knowledge about human biology.
