As syphilis rates increase in Los Angeles County zovirax200mg.com.

As syphilis rates increase in Los Angeles County, new study suggests the condition is increasing HIV rates The syphilis epidemic among men who have sex with men in LA County may be adding to rates of HIV in this population, according to a new report published in the Journal of Acquired Immune Deficiency Syndrome. The authors of the statement analyzed specimens banked from guys with early syphilis, from the Los Angeles County Public Wellness Laboratory. Using advanced statistical analysis, the researchers concluded that the annualized HIV incidence was 17 percent among all men with early syphilis zovirax200mg.com . Among the subgroup of men who’ve sex with males with early syphilis, the annualized HIV incidence was also higher at 26 percent. These total results suggest a high rate of HIV acquisition among MSM with early syphilis, and raise strong general public health concerns, given the many cities in the usa with increased syphilis prices among communities of MSM at risk for or affected by HIV disease.D., M.P.H., Director of the STD System and a co-author of the study. Syphilis is an illness transmitted through sores, throughout unprotected sex usually. In its early stages, syphilis can be quickly treated with penicillin. Based on the Centers for Disease Avoidance and Control, the reported amount of HIV attacks increased in 29 says from 1999 to 2002, including a 17 percent boost among MSM. This tendency suggests a possible resurgence of HIV transmission in this at-risk people. Moreover, the syphilis epidemic which Los Angeles County has been going through since early 2002 remains unabated. In 2004, approximately two-thirds of the a lot more than 800 syphilis cases reported in Los Angeles County happened among MSM; almost two-thirds of MSM with syphilis have been contaminated with HIV also.D., M.P.H., Director of General public County and Health Wellness Officer. The high rate of syphilis and HIV co-infections among MSM underscores the ongoing importance of public health efforts on several fronts: integrated HIV/STD testing that is easy to get at, and heightened disease surveillance to monitor trends in syphilis and HIV. Public Health is focused on protecting and enhancing the health of the almost 10 million residents of Los Angeles County. Through a variety of programs, community partnerships and services, Public Wellness oversees environmental health, disease control, and community and family health.

Artificial skin could give prosthetics sense of touch In a stage toward providing prosthetic limbs a feeling of touch, scientists have developed an artificial skin that may feel pressure and send those signals to brain cells. Reporting in the Oct. 16 problem of Science, researchers say the plastic epidermis mimics the ability of human pores and skin to inform the difference between a company handshake and the dead-fish variety. It could then transmit that information to cells of the central nervous system. Up to now, the principle has just been tested using human brain cells from mice, and much function remains before it may be useful for those who have prosthetic limbs. But, we know what we have to do to move this forward, and I’d estimate this could be available in three to six years, stated researcher Alex Chortos, a doctoral candidate at Stanford University, in California. Recent years have seen major developments in the function of prosthetic limbs, and the robotic aspects of contemporary prosthetics are quite good, Chortos stated. What’s remained elusive, he stated, are prosthetics that can provide the sensory responses that real limbs perform. That’s partly as the interaction between human being skin and the brain is indeed complex. One hands has roughly 17,000 sensors in it, Chortos said. And the ones sensors pick up different types of information. At this true point, the artificial pores and skin produced by the Stanford team replicates one aspect of touch: the skin’s ability to detect pressure distinctions. The ultimate objective, Chortos said, is normally to develop an array of sensors that may feel temperature, textures and other sensations. The artificial skin consists of two layers: The top layer is normally a waffled plastic which has carbon nanotubes, which carry out power when pressure is positioned on the plastic. The bottom layer functions as a circuit that gets those electric impulses and translates them into biochemical text messages that nerve cells can read. In this scholarly study, the experts proved that the sensory signals could be transferred to brain cells from mice. If the skin were to be used with prosthetic limbs, how would sensory indicators reach the mind? Chortos said the target is to essentially allow the prosthetic to plug in to the nervous system. We see it being able to stimulate nerves that are left following the limb amputation, Chortos explained. Then those signals will go directly to the brain. The existing findings represent an important step toward that, stated Polina Anikeeva, an assistant professor at the Massachusetts Institute of Technology, in Cambridge, Mass. But it’s just portion of the puzzle, she added. CBSNews.com’s. At this time, we still don’t possess a technology that could feed the pressure indicators back to the peripheral nerves within the rest of the limb of an amputee, said Anikeeva, who co-wrote an editorial released with the study. So even if we are able to sense contact with an electronic device, she explained, it is challenging to make a communication interface between this device and the nerves. Eventually, Anikeeva stated, any widespread use of such prosthetics is based on people’s comfort with them. As it is, people opt for relatively simple prosthetic arms often, she said. That’s because more-advanced prosthetics are still no match for an all natural limb, Anikeeva added. Similarly, a prosthetic with artificial skin may likely have to meet a higher bar. In order to make a prosthetic ‘comfy’ for people, it would need to be able to feel in a way that mimics the sensation within an actual limb, Anikeeva said.
