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.

IN THE NEWS: Radioisotope-producing plant shutdown drags on

Chalk River nuclear plant to stay closed even longer
Is there anyone who is genuinely surprised to learn of further delays in reopening Atomic Energy of Canada Limited's Ottawa-area Chalk River nuclear facility?

Chalk River, which accounts for half the world's production of technetium-99 (an important radioisotope used in medical imaging exams), has been shut for repairs since leaks were discovered last summer. The temporary closing is only the latest of several in the past two years, and the series of shutdowns have thrown the nuclear medicine community into panic.

The nuclear plant's operator, AECL, announced last week that it wouldn't meet the March deadline it had proposed in late 2009. The new goal is to have everything up and running in April. [AECL news release]

The announcement should come as no surprise to readers of Canadian Medicine. No one likes a braggart, of course, but I can't help pointing out that, over a month ago, I predicted the March deadline wouldn't be met. [Canadian Medicine] The only surprise is that vindication came so far in advance of the actual deadline.

Surreptitious, unconscious pelvic exams exposed
Seventy-two percent of patients expressed disapproval of allowing medical students to practice doing gynecological exams on patients who have been anesthetized for a surgical procedure without obtaining consent, which is commonplace in teaching hospitals. The survey, which brings to light a practice that doctors and students have not spoken about widely in public, was conducted by a team of doctors and researchers from the University of Calgary and published in the January issue of the Journal of Obstetrics and Gynecology of Canada. [JOGC abstract (PDF)]

The Globe and Mail's medical columnist André Picard called for an end to the exams being done without consent, calling them unethical. "Patients have a right to say 'No.' They are not merely a collection of body parts to be practised on." wrote Mr Picard. "Patients are due respect and ethical treatment, whether they are awake or anesthetized, and no matter how potentially embarrassing the procedure may be." [Globe and Mail]

Quebec MDs request regular pay for Haiti volunteer work
Quebec orthopedic surgeons who volunteered to go to Haiti are now formally requesting that the provincial government pay them $704 per day while they're away. "A spokesperson for the Quebec's association of orthopedists said that while doctors are volunteering in Haiti, they still have bills to pay in Quebec," reported CBC News. The Quebec Ministry of Health has not responded to the request yet.

Ostracizing smokers poses health threats: MD
In his new book "Écrasons la cigarette pas les fumeurs," published last month by Québec Amérique, Quebec psychiatrist Jean-Jacques Bourque says some smokers are harmed by overzealous doctors' urgings to kick cigarettes. Dr Bourque "démontre comment Santé Canada se prête à une propagande de peur en occultant les risques qu'affronte une certaine partie de la population en cessant de fumer." (He shows how Health Canada has undertaken a propaganda campaign of fear without recognizing the risks that a certain portion of the population faces by quitting smoking.)

Dr Bourque says he thinks many psychiatrists agree with his views but are contradicted by other specialists. [Le Soleil]

"I think we need to show compassion, empathy and understanding towards those who are dealing with such difficulties instead of setting them aside," Dr Yves Lamontagne, the president of the Quebec College of Physicians, told the Montreal Gazette. Dr Lamontagne, who quit smoking two years ago, wrote an introduction to Dr Bourque's book.

Dosage may need adjusting by patient weight
A new paper in The Lancet says drug dosages should be tailored to patients' weights. [ (subscription required)]

Dr Matthew Falagas, one of the report authors, said of himself (198 pounds) and a female student of his (120 pounds), “If we go with the same diagnosis of pneumonia or bronchitis to a New York hospital today... we will be given the same dose of antibiotics," he told The New York Times. "I should receive almost twice the dose compared with her.”

Orbinski gets Order of Canada
Dr James Orbinski, a University of Toronto professor of global health and the former Médecins sans frontières international president, was awarded membership in the Order of Canada "for his contributions as a physician who has worked to improve health care access and delivery in developing countries, and as an advocate for those who have been silenced by war, genocide and mass starvation." [Governor General of Canada news release] Also awarded on the same day were film director and producer Ivan Reitman (whose oeuvre includes"Ghostbusters" and "Stripes" as well as "Kindergarten Cop," "Trailer Park Boys: Countdown to Liquor Day" and many others) and hockey star Mario Lemieux.

RE: what is happening in the world of nuclear " fission" and " fusion"

here is a good read ensconced within your provided links:

* There is room for both "prediction" ( aha!) and " forecasting"(I see! ) in this arena,

RE: Officer of Canada

Congrats to all recipients in the "health" categories

RE: Women under anaesthesia

They say " a little knowledge is a dangerous thing".

I say " too much knowledge creates a precautionary reality"

Having attended the operational theatre ,for many different reasons, my greatest hope is that when I am under anaesthesia that what is "done" or "said" to/for/about my physical body .......... would be undergirded with the "highest respect" for my person....

...I live in hope..... :(

RE: "Opportunity" costs for doctors

It is a genuine reality that the money you "lost" (through lack of opportunity to earn it) has real value.
Therefore some concession should be made to any " earning" person ( in any vocation) to have at least a tax concession for proven " acts of mercy" that disturbed their earning pattern.
The route of reimbursement should be initiated by whomever the "sender" is.

Great, In my opinion simply done a fanatastic level. You certainly fully understand just what you are talking about, and I might rather become powering that. Nice living then straight up but straightforward.


Best Regards,
