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.

Pesticide punch

Wading through the produce aisles

If you think apples don’t taste like they used to, you’re probably right. The Environmental Working Group (http://www.ewg.org/foodnews/) has just updated its list showing pesticide levels in 53 types of produce, and apples - formally No. 4 of their “Dirty Dozen” - now weigh in at No. 1!

Researchers at Purdue University in Lafayette, IN, analyzed 51,000 pesticide residue tests done over 10 years (2000-2009) by the U.S. Department of Agriculture and the Federal Food and Drug Administration. 98% of the apples tested contained pesticides out of over 700 samples. And most of the fruit and veggies under scrutiny had been washed and peeled, in order to represent more realistic eating conditions.

Others that made the Dirty Dozen were celery, strawberries and peaches - which contained 57 different chemicals - along with greens such as kale, lettuce and hot peppers - treated with as many as 97 pesticides.

If we stick to Canada’s Food Guide we’d consume a minimum of five servings of Mother Nature’s bounty every day. By choosing these from the least contaminated foods we’d ingest less than 2 pesticides. However, picking them from the Dirty Dozen would up our daily pesticide intake to 14 different chemicals - some of which are associated with nervous system disorders, chronic problems including cancer, endocrine system dysfunction, and lower intelligence levels in kids - who may (along with those in the fetal stage) be the most vulnerable to the synthetic residues.

There’s also evidence that the phosphorus-rich fertilizers used in fields have contributed to the toxic blue-green algae blooms in our freshwater lakes, reported to cause vision loss and difficulty walking in some people who’ve been in contact with it, but that’s another story.

When organic produce isn’t readily available -- at the market, or due to budgetary constraints - these lists could be your best shopping companions.
