Linked To Prostate Cancer and Chromosomal Abnormalities

Men considering having a vasectomy, convinced by their doctors that there are no detrimental health effects, may want to think even more carefully about their decision. Two large studies reported recently add to earlier evidence that a vasectomy may increase a man's risk of developing prostate cancer. Moreover, vasectomies can cause chromosomal abnormalities in sperm itself.

As comedian Benny Ross has stated "the inventor of vasectomies must of been a prison warden...who else would prevent these rambunctious little swimmers from getting to their destination."

Humour aside, vasectomies are no laughing matter.

Experts not directly involved in the two large studies on vasectomies call the research scientifically well designed, adding that they underscore the need for further research to assess the possible hazards of one of the most effective and ...widely used methods of contraception.

The studies found that men who had a vasectomy more than 20 years earlier faced up to an 89 percent greater risk of prostate cancer than men who had not had a vasectomy. The studies also found that the more time that had passed since a vasectomy, the greater was the risk of developing prostate cancer.

The studies, reported in The Journal of the American Medical Association, were largely financed by the National Institutes of Health. They were conducted by a team headed by Dr. Edward Giovannucci from the Brigham and Women's Hospital and Harvard University in Boston.

In 1990, a small study from Edinburgh, Scotland, found that an unexpectedly large number of men who had had vesectomies later developed testicular cancer.

Experts said the findings show a statistical association that required further study. No plausible biological cause for the association is yet evident. They speculated that such a biological mechanism might be related to the decreased amount of prostate fluid after a vasectomy or to suppression of immune reactions that affect cancer. The experts also noted that the studies might have been influenced by other non-detectable factors.

The editorial urged men who have had a vasectomy to undergo annual checkups for prostate cancer, which is the recommendation made by the urological group and the American Cancer Society for men 50 to 70 years old.


Doctors should inform men seeking a vasectomy about the new findings, the editorial said.

The World Health Organization, a United Nations agency based in Geneva, said the studies were not definitive but "of high scientific quality" and that the scientific design of the studies avoided many of the methodological problems of earlier studies, some of which did not find a link between vasectomy and prostate cancer.

Experts in the United States and at the W.H.O. said that additional studies were urgently needed because confirmation of the latest findings would have a critical effect on family planning programs. Crucial information could come from at least six ongoing studies in the United States and Europe, the W.H.O. said.

Indications of a link between vasectomy and prostate cancer from recent studies led the World Health Organization to convene a committee of 23 experts from 10 countries in 1991. They concluded that no changes in family planning policies concerning vasectomies were justified on the basis of the biological and epidemiological evidence available then.

W.H.O. officials said that they did not know why reports from the meeting had not been published, as it had been announced they would be, in The European Journal of Cancer.

How And Why Melatonin Is An Effective Cancer Treatment


Numerous studies have established melatonin as one of the most effective anti-cancer treatments in existence. It inhibits cancer cell growth and proliferation; it destroys cancer cells, stops angiogenesis (new tumor blood vessel growth), and prevents harmful forms of estrogen from stimulating cancer cell growth. Despite its success in clinical trials and in doctors' experiences with their patients, it has not been widely prescribed in conventional medicine, though its effects have proven to be superior to those of many chemotherapeutic drugs.

In one clinical trial, patients with glioblastoma, a type of brain cancer, were given either radiation and melatonin, or radiation alone. Twenty-three percent of the patients who took the melatonin were alive after a year, while none who had received only radiation were still alive. Similarly, in another study by oncologists in Italy, patients with non-small cell lung cancers who had failed chemotherapy were given melatonin. They were compared with other patients with non-small cell lung cancers who weren't given melatonin. A year later, 26 percent of the patients who had taken melatonin were still alive; whereas, none in the non-melatonin group remained alive.

Studies have also revealed melatonin to be more effective for treating pancreatic and lung cancers than a drug commonly used to treat these types of cancers. What's more, this drug may cost more than $4,000 per month, while twenty milligrams of melatonin cost approximately $11 per month.

Melatonin functions to destroy cancer in multiple ways. First, because it is toxic to cancer cells, it induces apoptosis, or cancer cell auto-destruction, as well as directly kills cancer cells. It also slows tumor growth through a variety of mechanisms, such as by inhibiting epidermal growth factor receptors on cancer cells. Epidermal growth factors play an important role in cancer cell growth and proliferation, so blocking their receptors on cancer cells prevents them from carrying out these roles.
 
Melatonin also stimulates the immune system and increases the cancer-killing activity of macrophages, monocytes, natural killer cells, T-helper cells and eosinophils, all of which are involved in cancer cell destruction.

Additionally, melatonin inhibits angiogenesis (new tumor blood vessel creation) from existing blood vessels. Tumors get their nutrition through blood vessels, and as they grow, they require an increasingly greater supply of blood vessels to feed themselves. Preventing new blood vessel growth limits their food intake and causes them to shrink or stop growing.

Melatonin has properties which enable it to block the effects of estrogen upon cancer cells; this is important because certain forms of estrogen stimulate the growth of hormonally-influenced cancers, such as breast, endometrial, ovarian and uterine cancers.

Finally, as an antioxidant, melatonin reduces inflammation, a condition that enables cancer's survival, and it scavenges free radicals so that they don't damage normal cells and make them vulnerable to further genetic mutations.

Despite these favorable statistics, melatonin is seldom recommended to patients in conventional medicine because the laws which govern the practice of medicine are drastically influenced by pharmaceutical interests, which prevent doctors from recommending it to their patients in lieu of expensive, damaging chemotherapy drugs. It is, however, an effective natural treatment that not only helps to prevent cancer, but which also plays an integral role in healing the body from it.

Nanoparticles May Cause Kidney and Brain Damage


Nanoparticles pose some interesting possibilities for the future of medicine and other technologies. Unfortunately, like most medicines, there’s a chance of some serious side effects in their use. A few weeks ago, I noted some preliminary research suggesting that nanoparticles could potentially impair cell function. Now two more studies have demonstrated more potential dangers involved in the use of nanoparticles.

Carbon Nanoparticles in the Environment Can Cause Kidney Damage

In a paper in the current issue of Nanotoxicology, researchers at Indiana University-Purdue University Indianapolis examined the effect of low concentrations of carbon nanoparticles on cells. Their focus wasn’t on the use of nanoparticles in medicine, but rather what effect incidental environmental contact with nanoparticles has on the body. In other words, they were focused on low concentrations. And even at that, they saw that carbon nanoparticles were able to penetrate kidney cells. That’s a problem, because damage to kidney cells could result in toxic waste products meant to be expelled from the body in urine could end up back in the bloodstream. Or vice versa – blood could penetrate into the kidneys where it’s not supposed to go.

This is a troubling result, because carbon nanoparticles are already in use in medicine and electronics, and that use is increasing. As one of the study authors said, “The human body needs intact barriers, whether it be skin, airway linings, gut walls or the kidney cells we looked at in this study. We need to gain a better understanding of how CNPs modify and change characteristics of barriers as these tiny particles become more common in the air we breathe.”

Titanium Dioxide Nanoparticles Can Cause Brain Damage in Fish

Another common type of nanoparticle is titanium dioxide. Titanium dioxide is very commonly used as a pigment, and in its nanoparticle form it can be found it quite a few sunscreens and other applications. Unfortunately, this may pose some significant risks. Researchers at the University of Plymouth have been able to demonstrate that titanium dioxide nanoparticles were able to cause brain damage in rainbow trout that had been exposed to them.

They found that the particles caused vacuoles (holes) to form in parts of the brain and for nerve cells in the brain to die. Although some effects of nanoparticles have been shown previously in cell cultures and other in vitro systems this is the first time it has been confirmed in a live vertebrate.
One of the researchers noted that the action of the nanoparticles has a parallel to mercury poisoning, which suggests that accumulation of the particles could have some damaging long term effects to wildlife and possibly people as well.

There is still more research to be done on the risks of nanoparticles, but the evidence so far is pretty worrisome. Given the potential benefits of nanoparticles, I’m hoping that some means can be found to produce them in ways that don’t pose risks to health and safety. Research into the mechanisms of potential harms is key to that effort.

Natural Health Products Regulations and the Consumer

Life Choice Brands (P.S.A.) - Health Canada evaluates natural health products for safety, efficacy and quality and issues a license for those products that meet the regulatory requirements of the Natural Health Products Regulations.

Products that have been licensed will bear an eight-digit number preceded by NPN (Natural Product Number) or DIN-HM (for homeopathic medicines). Sometimes a product may be licensed but the label will not yet have been updated to show the license number. In these cases consumers can verify whether a product has been issued a license by searching the Health Canada Licensed Natural Health Products Database (http://webprod3.hc-sc.gc.ca/lnhpd-bdpsnh/index-eng.jsp).

Products that have been reviewed by the NHPD for safety but are still undergoing review for efficacy and/or quality and have not yet received a license 180 days after their initial receipt by Health Canada are eligible to receive an Exemption Number (EN). Products with Exemption Numbers are considered to hold a license under the Natural Health Products (Unprocessed Product License Applications) Regulations and are thus legal for sale in Canada. Consumers can also verify whether a product has a valid Exemption Number, if it is not visible on the label, by searching the Health Canada Exempted Products Database (http://webprod3.hc-sc.gc.ca/product-produit/search-rechercheReq.do?lang=eng).

Both these databases are maintained up to date and reflect the current status of a given product.

Other sources of information on the Health Canada website include product advisories and warnings; however, this information is not always current and warnings / advisories from several years ago may still be found on the Health Canada website. This information does not necessarily reflect the current compliance status of a given company. Even though the reasons for the warnings would have been corrected by the company the outdated information may still be posted on the Health Canada website.

Consumers should verify the current status of a product by searching the Licensed Natural Health Products Database and/or the Exempted Products Database and/or discussions with the actual company.

How Exercise Impacts Stem Cell Biology, Makes Bones Instead of Fat



McMaster researchers have found one more reason to exercise: working out triggers influential stem cells to become bone instead of fat, improving overall health by boosting the body's capacity to make blood.
The body's mesenchymal stem cells are most likely to become fat or bone, depending on which path they follow.

Using treadmill-conditioned mice, a team led by the Department of Kinesiology's Gianni Parise has shown that aerobic exercise triggers those cells to become bone more often than fat.The exercising mice ran less than an hour, three times a week, enough time to have a significant impact on their blood production, says Parise, an associate professor.

In sedentary mice, the same stem cells were more likely to become fat, impairing blood production in the marrow cavities of bones.The research appears in a new paper published by the Journal of the Federation of American Societies for Experimental Biology."The interesting thing was that a modest exercise program was able to significantly increase blood cells in the marrow and in circulation," says Parise. "What we're suggesting is that exercise is a potent stimulus -- enough of a stimulus to actually trigger a switch in these mesenchymal stem cells."

The composition of cells in the bone marrow cavity has an important influence on the productivity of blood stem cells.In ideal conditions, blood stem cells create healthy blood that boosts the immune system, permits the efficient uptake of oxygen, and improves the ability to clot wounds.Bone cells improve the climate for blood stem cells to make blood.But when fat cells start to fill the bone marrow cavity -- a common symptom of sedentary behavior -- blood stem cells become less productive, and conditions such as anemia can result.

The findings add to the growing list of established benefits of exercise, Parise says, and suggest that novel non-medicinal treatments for blood-related disorders may be in the future."Some of the impact of exercise is comparable to what we see with pharmaceutical intervention," he says. "Exercise has the ability to impact stem cell biology. It has the ability to influence how they differentiate."
