During the theoretical exam 3 titles are to be worked out and presented orally and one photo about a slide (with different magnifications) has to be described and diagnosed also orally discount cialis 10 mg visa. During the theoretical exam 3 titles are to be worked out (one from the material of the 1st semester, and two from the material of the 2nd semester). One photo about a slide (with different magnifications) has to be described and diagnosed (from the whole year). At least a (2) level of gross pathological examination and recognition of the histopathological alteration achieved in the course of a previous unsuccessful examination is acceptable without repeating for the next (B or C chance) examination. Cancer registries 6th week: Lecture: Role of viruses in the malignant transformation. Lecture: Prevention strategies in cancer 7th week: Lecture: Chemical carcinogenesis. Carcinogenic Requirements One of the main objective is to provide sufficient theoretical background to the basic principles of carcinogenesis, cellular and molecular biology of cancer, the effect of lifestyle, social factors and nutrition on tumorigenesis. In order to highlight the importance of the various environmental factors in the development and progression of cancer, detailed information is given in the following areas: the health effect of various chemicals and occupational exposures, health hazard of ionizing and nonionizing radiation and the role of viruses in malignant transformation. The genetic background of various cancers will be discussed based on molecular epidemiological data. The course provides sufficient background to pathobiochemical alterations associated with tumor growth and tumor metastasis, characteristics of benign and malignant tumors and malignant cell populations. The course also aims to give up-to-date information on cancer epidemiology, the major issues in screening programmes and the benefit and role of screening tests and prevention strategies.

Compensation for missed seminars should be paid according to the Rules and Regulation of the Faculty of Medicine, University of Debrecen. If the student is absent from more than 2 seminars/practices in a semester (without any acceptable reason), the Department may refuse to sign the Lecture Book. The curriculum also contains the hand-outs based on the lectures, given during the seminars. Seminar: Post-modern knowledge and concept of man in medicine: a critical-interpretive approach to medical 12th week: anthropology. Course Objectives and Course Outline: The object of medical anthropology is the human being, as he/she appears in the context of health and disease, in the healing processes and in the health-care system. The basic method of medical anthropology is historic-hermeneutical in the sense that man is investigated by this discipline in historical and cross- cultural relations; it is an integrative study and in this role it uses the contributions of different forms of knowledge (philosophical anthropology, social philosophy, cultural anthropology, psychoanalysis, sociology, etc. The medical anthropology semester consists of 15 hours seminar; these are organised in two-hour seminars in every second week. Method: Every student should actively participate by presenting a short lecture on a chosen topic (possibly in group- work). One hour from the 15 hour course will be reserved for tutorial discussion with the instructor during the preparation period. Every student should read a given paper for every seminar and is expected to put the presenters questions concerning the topic a few days before the seminar. The seminars can only be successful, if students participate actively in the discussions. The first 2nd week: encounter: psychological characteristics and functions of Lecture: Psychological causes and consequences of history taking and of the diagnostic process. Psychological support of Requirements Requirements for signing the lecture book: By signing the Lecture Book the Department confirms that the student has met the academic requirements of the course and this enables him/her to take the examination. The Head of the Department may refuse to sign the Lecture Book if a student: is absent more than twice from practices even if he/she has an acceptable reason. The Department of Behavioural Sciences will adhere to the requirements of the General Academic Regulations and Rules of Examinations.

The Proventriculus and Ventriculus Anatomy and Physiology55,101 The avian stomach consists of a cranial glandular part (proventriculus) and a caudal muscular part (ventriculus). The proventriculus in birds is situated in the left dorsal and left ventral regions of the thoraco-abdominal cavity, and is covered ventrally by the fat-laden posthepatic septum (see Color 14). The pyloric part of the ventriculus joins the duodenum and is located on the right side of the midline. In granivorous, insectivorous and herbivorous birds, the muscular wall of the ventriculus is highly devel- oped and is clearly distinct from the proventriculus. The two organs are divided by an intermediate zone, or isthmus, which can be seen grossly as a constric- tive band (Figure 19. The proventriculus can be seen laying dorsal to the caudal thoracic The proventriculus has two types of glandular epi- air sac.

These pharmaceutical-grade fish oil concentrates are so superior to earlier fish oil products that they are revolutionizing nutritional medicine discount 2.5 mg cialis with mastercard. Alternatively generic 20 mg cialis free shipping, vegetarian sources of long- chain omega-3 fatty acids produced from algae are now available cheap cialis 2.5mg otc. While most Americans eat way too much of the omega-6 oils found in meats and most vegetable oils buy cialis 10mg free shipping, they suffer a relative deficiency of the omega-3 oils—a situation that is associated with an increased risk for heart disease and about 60 other conditions including cancer, arthritis, stroke, high blood pressure, skin diseases, and diabetes. Although the body can convert alpha-linolenic acid (a short-chain omega-3 fatty acid found in flaxseed oil, walnuts, chia, and many other nuts and seeds) to the longer-chain omega-3s, it is not a very efficient process. The answer has to do with the function of these fatty substances in cellular membranes and inflammation. Without a healthy membrane, cells lose their ability to hold water, vital nutrients, and electrolytes. They also lose their ability to communicate with other cells and be controlled by regulating hormones. Cell membrane dysfunction is a critical factor in the development of virtually every chronic disease, especially cancer, diabetes, arthritis, and heart disease. Not surprisingly, long- chain omega-3 fatty acids have shown tremendous protective effects against all of these diseases. They regulate inflammation, pain, and swelling; they play a role in maintaining blood pressure; and they regulate heart, digestive, and kidney function. Prostaglandins also participate in the response to allergies, help control transmission of signals along the nerves, and help regulate the production of steroids and other hormones. Through their effects on prostaglandins and related compounds, long-chain omega- 3 fatty acids can mediate many physiological processes, so they are useful in virtually every disease state as well. Eating a diet rich in omega-6 and low in omega-3 fatty acids strongly promotes inflammation, which underlies many diseases and is associated with a significantly increased risk for many cancers—most notably breast and prostate cancer. Quality control is an absolute must to ensure that the product is free from heavy metals such as lead and mercury, pesticides, lipid peroxides, and other contaminants. In addition to taking a high-quality fish oil, we think it is also a good idea to take 1 tbsp flaxseed oil per day. Flaxseed oil is unique because it contains the essential fatty acids alpha-linolenic acid (an omega-3 fatty acid) and linoleic acid (an omega-6 fatty acid) in appreciable amounts. Do not cook with flaxseed oil, because it is easily damaged by heat and light; add it to foods after they have been cooked, or use it as a salad dressing. You can also try dipping bread into it, adding it to hot or cold cereal, or spraying it over popcorn. Here is a sample salad dressing featuring flaxseed oil: Flaxseed Oil Basic Salad Dressing 4 tbsp organic flaxseed oil 11/2 tbsp lemon juice 1 medium garlic clove, crushed Pinch of seasoned salt or salt-free seasoning Freshly ground pepper to taste Place all ingredients in a salad bowl and whisk together until smooth and creamy. Jazz up this basic recipe to your own personal taste by using your favorite herbs and spices. Those deficient in vitamin D have twice the rate of death and a doubling of risk for many diseases, such as cancer, cardiovascular disease, diabetes, asthma, and autoimmune diseases such as multiple sclerosis. We produce vitamin D3 (cholecalciferol) in our body by the reaction of a chemical in our skin in response to sunlight. The human genome contains more than 2,700 binding sites for calcitriol; those binding sites are near genes involved in virtually every known major disease. There are two primary forms of supplemental vitamin D: D3 (cholecalciferol) and D2 (ergocalciferol). Supplemental vitamin D3 is derived from either lanolin or cod liver oil extract and is the form of vitamin D that most effectively treats vitamin D deficiency. Vitamin D2 is derived from fungal sources, so it is sometimes referred to as vegetarian vitamin D. Unfortunately, vitamin D2 is not naturally present in the human body and may have actions within the body different from those of vitamin D3. Working and playing indoors, covering up with clothes or sunscreen when outside, or residing at a high latitude can make it likely that individual gets insufficient exposure to sunlight. Seniors are at greater risk due to lack of mobility (which means they may be less likely to be outside) and skin that is less responsive to ultraviolet light. A high incidence of vitamin D deficiency and its associated conditions in darker-skinned individuals is widely documented. Breastfeeding will result in vitamin D deficiency in the baby if the mother fails to ensure her own levels are high enough to provide for her baby’s needs. When the mother is deficient, the breast-fed child will be deficient due to the low vitamin D content of the mother’s breast milk. Fat-soluble vitamin D gets trapped in fat tissue, preventing its utilization by the body. Physical Care A critical component of overall good health is the physical status of the body. Pregnancy obviously results in an increased need for nutrients, including vitamins and minerals. Deficiency or excess of any of a number of nutrients can lead to birth defects in the baby and/or complications during pregnancy for the mother. In addition to eating a highly nutritious diet that focuses on whole, unprocessed foods, it is very important to take the following supplements: 1. A deficiency of virtually any nutrient during pregnancy is going to have serious repercussions for mother and baby. Furthermore, adequate levels of key nutrients such as antioxidants, calcium, magnesium, and other B vitamins may help ensure a healthy pregnancy and delivery by preventing complications of pregnancy such as gestational diabetes and the potentially life-threatening condition preeclampsia (also known as toxemia of pregnancy). Simply stated, taking a multiple vitamin and mineral supplement designed specifically for pregnant and lactating women makes perfectly good sense. The only caveat is to make sure that the vitamin A content is provided by beta-carotene rather than retinol. Usually the amount of iron contained in a prenatal multiple is sufficient, but if a mother-to-be develops anemia or has evidence of low iron stores (serum ferritin is the best determination), then additional supplementation is required. Ferrous sulfate is the most popular iron supplement, but it is certainly less than ideal, as it often causes constipation or other gastrointestinal disturbance. The best forms of iron supplements are ferrous succinate, ferrous glycinate, ferrous fumarate, and ferrous pyrophosphate. Of these, we prefer ferrous pyrophosphate that is micronized (very small particle size) and then microencapsulated. The advantages of this form are that it is extremely stable, has no taste or flavor, is free from gastrointestinal side effects, and provides a sustained-release form of iron (up to 12 hours) with a high relative bioavailability, especially if it is taken on an empty stomach. For iron deficiency during pregnancy, a woman will need to take an additional 30 mg iron twice per day between meals for best absorption. If this recommendation results in abdominal discomfort, then try the pyrophosphate form, or the supplement can be taken with meals three times per day.
