Improvement upon Microbicides? May Viagra Possess Rigid Competitors?

Scientist in China Take First Step in Developing Microbicide

In anew study published in the Journal of Biological Chemistry, Chinese researchers write about discovering a molecule that blocks HIV from entering into human cells. Researchers believe this could eventually be developed into a microbicide that could reduce the sexual transmission of HIV.

Scientists around the world have been searching for an HIV microbicide — a gel, foam, cream, or suppository that when applied topically inside the vagina or rectum could decrease or prevent sexual transmission of HIV. Also cheap dildos of interest are microbicides that include a spermicide (thereby also preventing pregnancy). The World Health Organization (WHO) has said this about the importance of microbicides:

According to WHO, there are no effective microbicides currently available.

The new study could represent an important advance toward development of an effective microbicide. Researchers believe the molecule they discovered, TD-0680, could be developed into a gel that would prevent sexual transmission by killing off the virus as it tries enter the body. Unprotected sex accounts for more than 90 percent of AIDS infections in China, the researchers said in a statement.

Lady in Red: Research Suggests that Men Think Women in Red Are Up for Sex

The color red has many connotations in our society: think scarlet letter or red state/blue state. It also makes you hungry which is why interior designers Amazon suggest it for dining room walls.

earch on November 15 at the Society for Neuroscience annual meeting in Washington, D.C. He conducted the study with Zachary Weil, research assistant professor, and Randy Nelson, professor and chair, both from Ohio State's Department of Neuroscience.

Previous research has most often examined the effects of adolescent sex on young women, and for ethical reasons must be done in humans as retrospective explorations of behavior. The Ohio State scientists used hamsters, which have physiologic similarities to humans, to learn specifically how the body responds to sexual activity early in life.

There is a time in nervous system development when things are changing very rapidly, and part of those changes are preparations for adult reproductive behaviors and physiology, Weil said. There is a possibility that environmental experiences and signals could have amplified effects if they occur before the nervous system has settled sexflesh rebellious ryan down into adulthood.

The scientists worked with five groups of male hamsters: two groups that had sex at age 40 days and were assessed at 40 days and 80 days after exposure to sex, two groups that had adult sex at age 80 days and were assessed at the same time intervals, and hamsters that had no sexual experience. Male hamsters reach puberty at age 21 days.

The researchers placed the adolescent and adult males in environments with in-heat female hamsters for six hours and recorded their encounters to ensure that sexual activity occurred.

The animals were subjected to a variety of tests when they all had reached adulthood. They were placed in mazes with options to explore open areas or hide in isolation; those that chose not to explore were showing signs of anxiety. Animals placed in water showed signs of depressive-like behavior if they stopped swimming vigorously.

Both groups of sexually active hamsters showed an increase in anxiet.
