Создается гель который защитит при анальном сексе от ВИЧ

Создается гель который защитит при анальном сексе от ВИЧ

В США начались клинические испытания геля на основе тенофовира в качестве микробицида при анальном сексе. Ранее опубликованные данные позволяют предполагать, что тенофовир частично снижает вероятность передачи ВИЧ при вагинальном половом акте.

Исследование будет проходить в трех американских университетах, в нем примут участие 60 добровольцев — как мужчин, так и женщин. За многолетнюю историю поисков микробицида испытания профилактического геля для анального секса проводятся всего в третий раз.

На сегодняшний день наиболее надежным средством профилактики ВИЧ при сексуальных контактах остается презерватив. Тем не менее создание альтернативы презервативам — микробицидного геля или крема — остается приоритетным направлением исследований. Очевидно, что для МСМ (мужчин, практикующих секс с мужчинами) особенно важны исследования по разработке анального микробицида.

Тенофовир (Виреад) уже давно применяется для лечения ВИЧ-инфекции. Исследование, проводившееся в ЮАР в 2009 году, показало частичную эффективность вагинального геля с содержанием тенофовира: среди женщин пользовавшихся микробицидом передача ВИЧ происходила на 39% реже, чем в контрольной группе.

Что касается испытаний тенофовира в качестве анального микробицида, пока речь идет только об оценке безопасности препарата. В частности, ученые хотят исключить возможность того, что вещество будет не защищать от ВИЧ, а наоборот, способствовать его передаче. Также будет оцениваться удобство применения геля.

Новость о первой фазе испытаний тенофовира в качестве потенциального анального микробицида вызвала положительную реакцию в научном сообществе. Результаты исследования ожидаются в начале 2011 года.

    Интересно узнать стоимость данного геля, а так думаю он вполне хорош будет, да и многим гей парам он действительно сможет помочь, так что рассчитываю на лучшее.

    I am the proprietor of JustCBD brand (justcbdstore.com) and am trying to grow my wholesale side of company. I really hope that anybody at targetdomain give me some advice. I considered that the best way to accomplish this would be to talk to vape companies and cbd stores. I was really hoping if anybody at all could suggest a trustworthy web-site where I can get CBD Shops B2B Marketing List I am presently checking out creativebeartech.com, theeliquidboutique.co.uk and wowitloveithaveit.com. Unsure which one would be the most suitable selection and would appreciate any support on this. Or would it be simpler for me to scrape my own leads? Ideas?

    An intriguing discussion is worth comment. I do think that you need to publish more about this issue, it may not be a taboo matter but typically folks don’t talk about these issues. To the next! Best wishes!

    The next time I read a blog, Hopefully it won’t disappoint me just as much as this one. After all, I know it was my choice to read through, but I really thought you would have something interesting to talk about. All I hear is a bunch of moaning about something that you can fix if you weren’t too busy seeking attention.

    There are absolutely a lot of information like that to think about. That is a fantastic indicate bring up. I provide the ideas over as general motivation but clearly there are concerns like the one you bring up where one of the most essential point will certainly be working in truthful good faith. I don? t know if best methods have arised around things like that, however I make sure that your work is plainly identified as a fair game. Both kids as well as women really feel the effect of just a moment? s enjoyment, for the remainder of their lives.

    I? m satisfied, I must say. Actually hardly ever do I encounter a blog that? s both educative as well as enjoyable, and also let me inform you, you have struck the nail on the head. Your idea is outstanding; the concern is something that insufficient people are speaking wisely around. I am extremely satisfied that I stumbled across this in my look for something connecting to this.

    Good message. I find out something extra challenging on various blog sites everyday. It will constantly be stimulating to review web content from various other authors and practice a little something from their store. I? d prefer to use some with the content on my blog site whether you don? t mind. Natually I? ll give you a link on your internet blog. Thanks for sharing.

    Can I just say what a relief to locate someone that actually recognizes what theyre discussing on the web. You absolutely recognize just how to bring a problem to light and make it important. Even more individuals need to read this and also understand this side of the story. I angle think youre not extra popular since you definitely have the present.

    You actually make it seem so easy with your presentation but I find this topic to be actually something which I think I would never understand. It seems too complex and extremely broad for me. I’m looking forward for your next post, I’ll try to get the hang of it!

    In these days of austerity and relative panic about getting debt, some people balk about the idea of having a credit card to make purchase of merchandise or perhaps pay for any occasion, preferring, instead only to rely on the actual tried along with trusted method of making transaction — hard cash. However, if you’ve got the cash available to make the purchase in full, then, paradoxically, this is the best time just to be able to use the credit card for several reasons.
