Now, an HIV blocking gel for ladies

WASHINGTON: Scientists have developed a “molecular condom”, which they declare is definitely a vaginal gel that will assist shield ladies from contracting the lethal HIV throughout sexual activity.
According to them, earlier than intercourse, ladies must insert the vaginal gel that turns semisolid within the presence of semen, trapping AIDS virus particles in a microscopic mesh to allow them to’t infect vaginal cells.

“The first step within the difficult technique of HIV an infection in a girl is the virus diffusing from semen to vaginal tissue. We wish to cease that first step. We’ve created the primary vaginal gel designed to stop motion of the AIDS virus. This is exclusive. There’s nothing prefer it.
“We did it to develop applied sciences that may allow ladies to guard themselves towards HIV with out approval of their associate,” stated lead scientist Prof Patrick Kiser of the University of Utah.

According to the scientists, attributable to cultural and socioeconomic elements, ladies usually are unable to barter the usage of safety with their associate.

“So we developed a vaginal gel {that a} girl may insert a couple of hours earlier than intercourse and will detect the presence of semen and supply a protecting barrier between the vaginal tissue and HIV. We needed to construct a gel to cease HIV from interacting with vaginal tissue.

“It flows at a vaginal pH, and the circulation turns into slower and slower as pH will increase, and it begins to behave extra stable on the pH of semen,” co-scientist Julie Jay stated.

The scientists estimate that if all goes effectively, human checks of the gel would begin in three to 5 years, and the gel would attain the market in a number of extra years.

The findings of their experiment testing the behaviour of the vaginal gel and displaying the way it traps AIDS-causing HIV particles are to be printed within the upcoming version of the ‘Advanced Functional Materials’ journal.
