“Field Testing” for genetic problems?
Question by Loki Wolfchild: “Field Testing” for genetic problems?
Some breeders of working dogs (in the general sense of “a dog that works”, not the Working Group) believe in “field testing” their dogs for genetic issues, rather than having them screened. The basic premise is that if the dog can do its work, it must be healthy…a dysplastic dog could not run all day, a dog with eye problems could not retrieve, a dog with heart problems would not have the endurance for the job, etc.
After all, health databases and genetic testing have only been around for the past 50 years or so (some much less!)…and most of these breeds have been working much longer than that.
Do you believe that this is a sensible, ethical approach in modern times? Why or why not?
Would you buy a working-line dog from a breeder who believed in this theory, knowing that your dog’s pedigree had no certifications for several generations?

Leigh: Excellent point. I expect my sled dogs to continue working at 12-13 years old…after all, Togo was 12 when he led Seppala’s team 261 miles during the 1925 Serum Run.
My dogs are not disposable.

No, because what if both the bitch and the dog were carriers of a gene that was not dominant? It would not show up in the dogs yet the trait could appear in the pups and not be seen until much later in life.

The Link Between Genetics And Colon Cancer
The Link Between Genetics And Colon Cancer
Genetic drift , selection , migration, etc., are parameters which are used to construct models that allow us to generate predictions and obtain deeper insight.
The discovery of DNA and the elucidation of the biophysical substrate which constrains the modes of inheritance in a concrete manner opened up the startling vistas of molecular evolutionary genetics. Generally, gene mutations can disrupt an entire protein, but in colon cancers, only half the APC protein is lost, while the other half remains, Ahmed explains. Her work in fruit flies suggests a reason for this unexplained phenomenon.
Genes, such as Notch 3, were affected by the stage of tumorigenesis. After pathway analyses, many genes were identified that were over-represented for their respective biological processes (genes involved in the metabolism of carbohydrates and lipids, ion transport and signaling pathways).
Colon cancer is very rare in people under 30 years of age. Most people diagnosed with the disease are in their 50?s or 60?s. Colon cancer is one of the most common forms of cancer in the United States for both men and women. Also referred to as colorectal cancer, colon cancer occurs in the large intestine (colon) or the rectum (end of the colon).
Colon cancer is the second-leading cause of cancer deaths. The best way to detect colon cancer is with a colonoscopy, a screening exam that involves inserting a flexible, lighted tube through the rectum up to the colon and viewing images on a monitor.
Colon cancer is often fatal if the cancer cells have spread unchecked through the lymphatic system or bloodstream to adjacent and/or distant tissues. Colorectal cancer has a strong tendency to metastasize to the liver, which represents the leading cause of death for people with the disease.
Colon cancer is preventable. The most important step towards preventing colon cancer is getting a screening test. Colon cancer is caused by the abnormal growth of cells in the lining of the bowel. Usually small lumps called polyps begin to form.
Generally, the less the olive oil is handled, the closer to its natural state and the better it is. Generally, the deeper a tumor has penetrated the bowel wall, the more difficult it is to cure with surgery alone. Generally, digestive diseases have been considered by psychiatry to result from anger turned inward.
It is now known that normal people’s immune systems are able to recognize and destroy tiny cancer cells before they can spread. In the diseased or depressed person, the immune system does not function efficiently and may allow cancer to start.
Screening works because colon cancer is usually a slow-growing disease that starts with adenomatous polyps, small, protuberant growths inside the colon that may contain precancerous cells.
Screening tests are designed to find these polyps so doctors can remove them before they become cancerous. Screening saves lives.”.Here are some myths about colon cancer and the facts patients need to know. Myth: Colon cancer only affects men Colon cancer affects both men and women, in fact approximately 26,000 women die every year from colon cancer.

Regular Dental Exams Prevent Life Threatening Health Issues
Regular Dental Exams Prevent Life Threatening Health Issues
There are many compelling reasons to visit a dentist regularly. Dental screenings check for a wide variety of problems, many of which are important to a patient’s overall health as well as their teeth and gums. In addition to a check for general oral health, the dentist screens for oral cancer, cavities, and early signs of gum disease. Regular visits assist the family dentist in getting to know patients’ habits and issues, increasing the ability to catch problems before they become health emergencies.
Routine dental screenings go further than patients may realize. A part of the procedure is a check for oral cancer. A regularly scheduled visit to the dentist provides the best screening for this cancer, which is curable unless it is discovered in the very late stages. Tobacco users are especially at risk; however, people with no known risk factors for oral cancer can still contract this disease. Recent studies have also linked the occurrence of oral cancer to the human papilloma virus, or HPV. Frequent dental check-ups are the best line of defense to fight oral cancer.
Regular dental check-ups provide an opportunity for the dentist to catch cavities before they develop into bigger problems. The dentist can spot tooth decay early on, and design a treatment plan that will keep the patient’s teeth healthy. Early intervention to stop minor tooth decay can prevent costly dental procedures and even loss of teeth down the road.
Dentists also check for the presence of gum disease during regular screenings. Gum disease, or gingivitis as it is called in the early stages, can be prevented through good dental hygiene and professional cleanings. In fact, some forms of decay, like tartar buildup, can only be eliminated by a dental cleaning. Gingivitis forms after plaque and other build up is allowed to remain (and decay) on the surface of the teeth and gums. While tobacco use and genetics contribute to the formation of gingivitis as well, regular dental treatment can help prevent the condition from developing into a bigger issue.
In advanced stages, gum disease becomes periodontal disease, which is truly a threat to overall health. This serious condition can lead to a patient’s bones breaking down, as well as tooth loss. Even more disturbing, bacteria that are present in a mouth full of infected gums can contribute to dire health issues such as heart disease and stroke.
Some researchers also suggest that gum disease raises the risk of developing diabetes. It is thought that infected gums can raise blood sugar levels, a contributing factor to this serious disease.
Surprisingly, current statistics show that the majority of Americans have gum disease in some form or another. This makes it all the more important to incorporate regular dental checkups in your plan to maintain overall good health.
Current recommendations suggest that adults and children should see their dentists at least every six months for a dental exam and cleaning. A regular visit with the family dentist is an essential weapon in the fight against very preventable conditions like tooth loss, gum disease, and oral cancer.
