Crean gel que puede prevenir la transmisión del VIH, VPH y Herpes en la vagina y el recto

alexiustoday:

Científicos del Population Council han encontrado que su gel microbicida es seguro, estable, y puede prevenir la transmisión de múltiples infecciones de transmisión sexual (ITS), tanto en la vagina como en el recto en los animales, tales como: el VIH, virus del herpes simple 2 (HSV-2), y el virus del papiloma humano (VPH). El estudio también proporciona los primeros datos de que el gel es eficaz contra múltiples cepas del VIH, y que tiene un margen de eficacia en la vagina contra los tres virus de al menos ocho horas antes de la exposición.

Estos hallazgos fueron publicados recién en PLoS ONE en un artículo titulado “A Potent Combination Microbicide that Targets SHIV-RT, HSV-2 and HPV”.

Una vacuna bloquea completamente la infección por VIH en monos

alexiustoday:

Una nueva vacuna relativamente simple que se puede administrar por vía oral ha logrado bloquear completamente la infección rectal con SIV, el equivalente en monos del VIH, en macacos rhesus y ha producido una rápida re-supresión de la carga viral en los monos que fueron infectados previamente con SIV. Los resultados se publicaron recientemente en Frontiers in Immunology.

"Curing AIDS? Shit, that’s like Cadillac making a car that lasts for 50 years. And you know they can do it, but they ain’t going to do nothing that fucking dumb. Shit, they got metal on the Space Shuttle that can go around the Moon and withstand  temperatures of up to 20,000 degrees, you mean to tell me you don’t think they can make an El Dorado with a fuckin’ bumper that don’t fall off?"

El VIH o su tratamiento tienen un efecto protector contra la esclerosis múltiple

alexiustoday:

Un equipo médico australiano e investigadores británicos analizaron los registros médicos de más de 5 millones de personas y ha descubierto que, o bien el VIH o medicamentos contra el VIH tienen un efecto protector contra la esclerosis múltiple (EM). Pacientes con SIDA o personas con VIH que reciben tratamiento tienen una probabilidad del 60% menos de probabilidades de recibir un diagnóstico de EM. La investigación fue publicada el 4 agosto de 2014  en el Journal of Neurology, Neurosurgery and Psychiatry.

Un análisis más profundo ha descubierto que aquellos con un régimen de tratamiento más largo, por 5 años o más, tenían un 80% menos de probabilidad de desarrollar EM. El descubrimiento es notable por el hecho de que no existen tratamientos curativos o preventivos para la EM y esta visión inesperada puede ser una de las vías más interesantes.

CANCER TREATMENT CLEARS TWO AUSTRALIAN PATIENTS OF HIV

Researchers have discovered that two HIV+ Australian men who were treated with stem cell transplant for cancer — one for non-Hodgkin’s lymphoma and the other for leukaemia — have become virus-free, presumably because the donor cells carried genes that confer immunity from it.
hey are still on antiretroviral therapy (ART) “as a precaution”, but those drugs alone could not be responsible for bringing the virus to such low levels, says David Cooper, director of the Kirby Institute at the University of New South Wales in Sydney, who led the discovery. A year ago, a different group of researchers had reported cases with a similar outcome.
Cooper presented details of the cases today at a press briefing in Melbourne, Australia, where delegates are convening for next week’s 20th International AIDS Conference. The announcement came just a day after the news that at least six people heading to the conference died when a Malaysia Airlines flight was shot down in Ukraine.
