Ho and Jeffrey V. Ravetch, Scheid and colleagues isolated 433 antibodies from these individuals’ blood serum that particularly targeted the envelope protein – the chink in HIV’s protean armor. He cloned the antibodies and created them in bulk, mapped which portion of the envelope protein each targeted, and gauged how effective each was in neutralizing the virus. In the process, he identified a new structure within the envelope protein – called the gp120 core – that had under no circumstances been recognized as a potential target for antibodies. It’s the first-time that anyone has described what is really occurring in the B cell response in these patients, says Scheid.Young athletes have to drink plenty of liquids and take breaks every single 10 to 15 minutes, the doctors said. They should put on light clothes and limit their exposure to the sun if they are outside during the hottest period of the day. One method to stay cool is to apply towels soaked in ice and drinking water to the head and neck. If a child is apparently suffering from heat illness, move the youngster in to the shade or coolest area nearby.
