Learn about Erectile Dysfunction and Sildenafil Citrate Online

Have you ever wondered how sildenafil acts within your body to help you solve your problems with erectile dysfunction?  Thanks to the instant availability of the Internet and computer devices, you will now be able to learn about ED and sildenafil citrate online right at your fingertips.

If you are curious as to how PDE5 inhibitors such as sildenafil work inside your body, then you can browse on search engines by simply typing in the search box the words sildenafil citrate online.  When you read about the mechanics of the action of sildenafil citrate online, you will learn that it helps protect the enzyme cGMP (short for cyclic guanosine monophosphate) from being degraded by the cGMP-specific PDE5 (short for phosphodiesterase type 5 enzyme) which are evidently located in the penile corpus cavernosum of men.  The free radical NO (short for nitric oxide) found in the penile corpus cavernosum adheres itself to what are called the guanylate cyclase receptors, which then results to the occurrence of elevated amounts of cGMP, thereby leading to the vasodilation or relaxation of the smooth muscles of the inner lining cushions of the helicine arteries (tendril-like arteries of the penis importantly involved in the process of its erection).  Once the smooth muscles relax, it will result to vasodilation and therefore there will be an increased supply of blood flowing into the penile spongy tissue, and the end result would be a successful penile erection.

Additionally, what you would also learn about sildenafil citrate online is that its special molecular makeup is somewhat similar to cGMP (located in the penile corpus cavernosum as well) and functions as an aggressive binding element of PDE5 in the penile corpus cavernosum, which results to more concentrations of cGMP and even better occurrences of erections. Avery important information that men will learn through reading about sildenafil citrate online is that sildenafil will be rendered useless without the introduction of one or more sexual stimuli, since only a sexual stimulus will be the only factor that can initiate the activation of the nitric oxide and cGMP inside a man’s body.

What's in the news: Oct. 16 -- The H1N1 flu's second wave is here

This month marks the beginning of what appears to be the anticipated "second wave" of the H1N1 flu pandemic in Canada, with clusters of cases appearing once again. [Toronto Star]

As doctors anxiously await the arrival of the vaccine, health officials are busy trying to simultaneously push back against rumours that the vaccine might be dangerous or useless and (so far unsuccessfully, it seems) convince people to wash their hands and stop coughing on one another.

Meanwhile, researchers around the world are still learning more about the virus and the disease it causes.

American government researchers found that people killed by the H1N1 flu have often had bacterial coinfections in their lungs, including with the bacterium pneumococcus. That means the pneumococcal vaccine is an important element in the effort to keep patients safe this flu season, the researchers said.

Early use of the H1N1 vaccine in China by the World Health Organization showed some very minor side effects, like headaches and muscle cramps.

Canada granted drug and vaccine manufacturer GlaxoSmithKline immunity in potential H1N1 vaccine lawsuits. "We're not obviously anticipating problems with it, but indemnification for a vaccine is important if someone does malpractice, basically injects someone the wrong way or causes harm because of their practice," Dr David Butler-Jones, the head of the Public Health Agency of Canada, told reporters. [Toronto Star]

British Columbia came to an agreement with its doctors to pay $14.74 for fielding H1N1-related phone calls. BC physicians should use the billing code PG13705 on their claims. Another new billing code, PG13700, will pay family physicians $31.15 for office visits to deal with the H1N1 flu. Both new fees will cease to be available when the Provincial Health Officer decides they are no longer necessary.

Contrary to the rumoured results of Canadian research that circulated recently, a new Mexican study suggests the seasonal flu shot might actually aid H1N1 flu immunity rather than encourage it. [Globe and Mail]

It turns out that a Manitoba reserve -- and not the federal government -- was responsible for requesting the large shipment of body bags that was responsible for a major controversy and much mudslinging at Health Canada. [Globe and Mail]

Several Winnipeg physicians recommended that doctors should make sure they have enough sedatives and antimicrobials on hand to treat H1N1-flu patients in the ICU. [CMAJ]

Using electronic text messages displayed in public restrooms, British researchers discovered that shame is the most powerful motivator in getting people to wash their hands, more so than reason or disgust. The lesson may be transferable. "A similar method of unobtrusive observation should also work for other kinds of behaviors important to public health, such as smoking cessation and alcohol moderation campaigns."

A Prince Edward Island physician surmised that an outbreak of the H1N1 flu virus in the Toronto Maple Leafs dressing room would wreak havoc on the team's ability to win hockey games. "Well," Dr Richard Schabas, the former chief medical officer of Ontario, told the National Post, "at least they are going to have an excuse this time."

What’s your recourse when web reviews get ugly?

Much the same way you can review books or rate your kitchen appliances, Canadian patients are busy kibitzing about their doctors online.
