Also, it was recently demonstrated that mutation or duplication (multiplication) of the a-synuclein gene is associated with Parkinsons disease . These clinical ndings suggest that the brain is extremely sensitive to perturbations in gene-regulation, and further indicate that the brain is an organ that requires a proper control system for gene expression. The term epigenetics was rst used by Conrad Waddington in 1939 to describe the causal interactions between genes and their products, which bring the phenotype into being .
The colon would frequently need new sup- plies of Clostridium to reinforce the colony there order 80 mg top avana with amex. The presence of clostridium bacteria in our intestines has been considered normal by scientists buy generic top avana 80 mg on line. Evidently at some time while growing up, the Bifidus disappear and Clostridium takes over. Yet, all American persons, even when well, harbored Clostrid- ium in the intestinal tract. Cancer patients, though, harbor Clostridium throughout the intestine, reaching all the way to the stomach! The cancerous organ, even as far away as the brain or eye, has been invaded by Clostridium, too. They can be pushed back down the tract, all the way to the colon, and even eliminated from there. If our teeth become colonized with Clostridium, they become a source of distribution to the colon and tumors. Tooth fillings, if imperfectly applied, create a crevice be- tween tooth and filling that is suitable for anaerobes to live in. If your teeth have gray or bluish-black discoloration, you probably have Clostridium in- fection. But of course it is hidden from view under a cap or crown or simply under a filling. They are usually all present when there are large plastic fillings, and when crowns, root ca- nals, or dead teeth are present. The next time you have a tooth extracted, ask the dentist to give it to you, so you can search for the thin, black lines of clostridium invasion yourself. Clostridia are not necessarily present under small fillings, such as those in front teeth. It is probably easier to get a small filling to stick perfectly to the tooth than a large one, so no crevice develops. Evicting The Colonies Once the teeth and colon have been colonized by Clostrid- ium, they can not be easily eradicated. No immune power can reach the colony in the teeth; there is no circulation to the fill- ings! Can the rest of the body be suf- ficiently oxygen- ated to prevent in- vasion by Clos- tridium? Can the tooth crevice, causing mi- croleakage, be sealed off so bacte- ria couldnt escape into the body? The in the crevice and plastic filling in the tooth on the right has a tooth be killed by black outline of bacteria. But if you have advanced cancer, you can not risk a tempo- rary solutiondont delay. Extract all your decayed teethteeth with caps, crowns, root canals, and large fillings of any kind. You will be accom- plishing more than just eliminating clostrid- ium bacteria, as you will soon see. While you are This tooth with its crown removed re- waiting for your first veals a black surface underneath and fine gray lines of further invasion of the dental appointment, tooth. No antibiotics, no change in diet, no extra lactobacillus or bifidus bacteria taken as a supplement can clear them. All clostridium species (as represented by my set of six slides) will be gone from the colon, all the way up to the stom- ach in three days, but not gone above the stomach nor in your tumors. Meanwhile, you should be brushing with oregano oil, just drop on your tooth- brush. Your body will feel an incredible relief when the clostrid- ium-infected teeth are gone. No antibiotics and no bandaging can control the blood poisoning that will develop if you do not extract the thorn. After extracting your decaying toxic teeth you still must do careful Dental Aftercare (discussed later), but the big step has been taken and you may now feel secure you can re- cover from your tumor-disease. Here the clostridia emerge and while attempting to travel through our bodies, may find a tooth crevice to survive in, as well as the colon. The colon will be more anaerobic as we age, perhaps be- cause it usually becomes more sluggish in later years. Use the Parasite Killing Program in the next section to eradicate the rabbit fluke. Getting rid of parasites would be abso- lutely impossible using clinical medicines that can kill only one or two parasites each. Flagyl is used for amoebas and Giardia; when the cor- rect dosage is used, it can cause extreme nausea and vomiting.
Imple- mentation of a gluten-free diet is important in these cases to avoid malnutrition (59) order top avana 80mg on-line. Supplements In healthy individuals buy generic top avana 80 mg on-line, it is crucial to support the body with adequate nutrients in order to optimize physical exercise and increase muscle mass or muscle endurance. Supplements have become an enormously profitable industry and the effect of most supplements on the market can be questioned. Through basic research, the safety of several different supplements for use in healthy people has been established (60). There is limited information available that is specific to patients with polymyositis and dermatomyositis; information that is available is presented further on in this chapter. A large number of studies have been published on the subject, describing the ergogenic outcome on muscle strength and size when using creatine in combination with resistance training . This provides the ability to work out at an enhanced level and results in a greater gain in muscle mass (65). Creatine supplements have recently been evaluated in a placebo-controlled trial in patients with myositis, in combination with stable immunosuppressive treatment and/or steroids (68). The creatine-supplemented group had a significant improvement, compared with the placebo group, in the primary outcome that reflected the ability to undertake high-intensity exercise. Side effects of creatine supplements, for example, muscle cramps and heat intol- erance, have been described. These side effects may be related to an increase in water retention during the initial days of supplementation. Water retention and an increase in muscle mass may cause weight gain while supplementing with creatine (69). The use of creatine supplements with exercise among patients with myositis was without significant side effects and was considered effective and inexpensive (68,70). In animal models with arthritis, it was suggested that creatine supplementation might have an anti-inflammatory action; similar suggestions have been made based on research using cell cultures in which creatine supplementation also had an anti- inflammatory action on endothelial cells. These effects may arise from the ability of creatine-supplemented cells to inhibit endothelial permeability and expression of adhesion molecules, decreasing the traffic of proinflammatory cells and mediators from the bloodstream into the tissue (71). Regarding creatine supplementation in general, the literature is based on adults, so there is a lack of data regarding safety of creatine use in growing adolescents. Therefore, no conclusions can be drawn for patients with juvenile dermatomyositis and creatine supplementation (72). Although creatine is a common supplement, commercially marketed creatine products might not meet the same quality control standards as pharmaceuticals, and because of possible impurities or differences in dosage, caution is urged. Patients should always discuss use of any dietary supplement with their physician. Anabolic Steroids Anabolic steroids increase muscle mass and strength, and have been used by athletes for decades. The use of anabolic steroids in sports was banned by the International Olympic Committee in 1974. Use of these hormones may generate several side effects, such as severe acne, increased body hair, and aggressive behavior that may occasionally trigger violent behavior (74). Without a prescription from a doctor, anabolic steroids are an illegal drug, and the use of hormones without a physicians surveillance could involve major risks. In recent years, anabolic steroids have been investigated in terms of possible benefits for patients with disease-related muscle wasting. Testosterone administration has had positive results in different patient populations, but because it is a natural androgen hormone, it possesses virilizing effects, which limits the population that can be treated. An alternative is oxandrolone, a synthetic testosterone analog, that also can be used in treating women and children with chronic muscle-wasting conditions (76). Under the controlled conditions of the trial, the adverse effects were minimal and the drug was considered safe and classified as a treatment of possible benefit (77). No controlled studies have been performed in patients with polymyositis or dermato- myositis, so whether oxandrolone has any effect in these disorders is not known. Glutamine Glutamine is a conditionally essential amino acid, meaning that it is essential during conditions of trauma, sepsis, or cancer. Glutamine provides the body with new precursors for energy substrates, antioxidants (mostly glutathione), and acute-phase proteins found in the blood shortly after onset of an infection (80). This mobilization leads to an intramuscular glutamine depletion, resulting in a decrease in lean muscle mass (81). Patients in intensive care may develop severe myopathies and muscle biopsies from these patients show low levels of muscle glutamine (82). Patients with myositis are treated primarily with glucocorticoids, which induce the release of glutamine into the blood at the expense of muscle protein degra- dation.

The core aspects of diseases in pathology Pathology is the study of disease by scientific methods. Diseases may, in turn, be defined as an abnormal variation in structure or function of any part of the body. Pathology gives explanations of a disease by studying the following four aspects of the disease. Knowledge or discovery of the primary cause remains the backbone on which a diagnosis can be made, a disease understood, & a treatment developed. Pathogenesis Pathogenesis means the mechanism through which the cause operates to produce the pathological and clinical manifestations. Morphologic changes The morphologic changes refer to the structural alterations in cells or tissues that occur following the pathogenetic mechanisms. The structural changes in the organ can be seen with the naked eye or they may only be seen under the microscope. Those changes that can be seen with the naked eye are called gross morphologic changes & those that are seen under the microscope are called microscopic changes. Both the gross & the microscopic morphologic changes may only be seen in that disease, i. Therefore, such morphologic changes can be used by the pathologist to identify (i. In addition, the morphologic changes will lead to functional alteration & to the clinical signs & symptoms of the disease. Functional derangements and clinical significance The morphologic changes in the organ influence the normal function of the organ. By doing so, they determine the clinical features (symptoms and signs), course, and prognosis of the disease. In summary, pathology studies:- Etiology Pathogenesis Morphologic changes Clinical features & Prognosis of all diseases. This understanding will, in turn, enable health care workers to handle & help their patients in a better & scientific way. In addition, the pathologist can use the morphologic changes seen in diseases to diagnose different diseases. Diagnostic techniques used in pathology The pathologist uses the following techniques to the diagnose diseases: a. Histopathological techniques Histopathological examination studies tissues under the microscope. Once the tissue is removed from the patient, it has to be immediately fixed by putting it into adequate amount of 10% Formaldehyde (10% formalin) before sending it to the pathologist. Once the tissue arrives at the pathology department, the pathologist will exam it macroscopically (i. It is then impregnated (embedded) in paraffin, sectioned (cut) into thin slices, & is finally stained. It gives the nucleus a blue color & the cytoplasm & the extracellular matrix a pinkish color. Cytopathologic techniques Cytopathology is the study of cells from various body sites to determine the cause or nature of disease. Applications of cytopathology: The main applications of cytology include the following: 1. Screening for the early detection of asymptomatic cancer For example, the examination of scrapings from cervix for early detection and prevention of cervical cancer. Diagnosis of symptomatic cancer Cytopathology may be used alone or in conjunction with other modalities to diagnose tumors revealed by physical or radiological examinations. It can be used in the diagnosis of cysts, inflammatory conditions and infections of various organs. Surveillance of patients treated for cancer For some types of cancers, cytology is the most feasible method of surveillance to detect recurrence. The best example is periodic urine cytology to monitor the recurrence of cancer of the urinary tract. Therefore, it is appropriate for developing countries with limited resources like Ethiopia. Exfoliative cytology Refers to the examination of cells that are shed spontaneously into body fluids or secretions. Abrasive cytology Refers to methods by which cells are dislodged by various tools from body surfaces (skin, mucous membranes, and serous membranes). Such cervical smears, also called Pap smears, can significantly reduce the mortality from cervical cancer.
