Only one absence is accepted from the obligatory lectures, in case of more absences the semester won’t be accepted. New scientific information connected to the lectures will also be presented; those materials will also be asked on the exams. Every laboratory practice must be performed, if someone is absent due to any serious reason proved by medical papers, the missing experiment have to be performed within the three weeks practice period joining to another group (after previous discussion with both practice teachers). In case of more than one remedial practice, students cannot get any points for that practice unit. The list of the chemical structures can be found in the biochemistry practical guide. In the first semester, grade will be offered on the basis of the collected points for all those students, who collected at least 60 points (and reached at least 60% of the practical points! Those, who did not collect 60 points, have to take a written exam in the exam period. At the written end-semester exam 50 points can be collected, it consists of single- and multiple choice test questions from the lecture material (45 points) and from the practice (5 points).

In a study conducted in Canada 100 mg lady era overnight delivery women's health clinic red deer, researchers found a twofold increased risk of prostate cancer associated with an increased intake of milk generic lady era 100mg mastercard women's health videos online. Interestingly cheap 100 mg lady era amex pregnancy cravings, it was the only dairy product associated with an increased risk for prostate cancer purchase lady era 100 mg fast delivery menstruation questions. It is also important to point out that the Mediterranean diet has been shown to help prevent prostate cancer. That would be expected given that it is high in vegetables, legumes, dried and fresh fruits, and ﬁsh; olive oil is its main fat source; it is low in animal fats, processed red meat, milk and dairy products; and it includes regular but low alcohol intake (wine with meals). The high intake of soy may be one of the key protective factors accounting for the low rate of prostate cancer in Japan and China compared with other parts of the world: blood and urine concentrations of soy isoﬂavones (an indicator of intake) were found to be 7 to 10 times higher in Japanese men consuming a traditional Japanese diet compared with Finnish men consuming a typical Western diet. Information on the isoﬂavone content of common soy foods can be found on page 788. Just as in breast cancer again, the beneﬁts of these long-chain omega-3 fatty acids are magniﬁed when the level of animal fat (saturated fat, and arachidonic acid in particular) is also reduced. A high ratio of dietary omega-6 to omega-3 fatty acids is major risk factor for prostate cancer. Unfortunately, no one has actually looked at the effect of ﬂaxseed oil in prostate cancer. At this time it appears that men in general may be better off avoiding ﬂaxseed oil supplements and focusing on ground ﬂaxseed (for the lignans) and ﬁsh (for the omega-3 fatty acids). Flaxseed Ground ﬂaxseed appears to be quite helpful not only in preventing prostate cancer but also in men with existing prostate cancer. In addition to its phytoestrogenic effect, ﬂaxseed lignans also bind to male hormone receptors and promote the elimination of testosterone. In a study of men with prostate cancer, a low-fat diet (with fat providing 20% or less of total calories) supplemented with 30 g ground ﬂaxseed (roughly 2 tbsp) reduced serum testosterone by 15%, slowed the growth rate of cancer cells, and increased the death rate of cancer cells after only 34 days. Although genetics could play a role, a more likely explanation is dietary differences. In a study conducted by the National Cancer Institute of men who had been newly diagnosed with biopsy-proved prostate cancer and matched controls without prostate cancer, it was shown that increased consumption of foods high in animal fat was linked to prostate cancer (independent of intake of other calories) among black men compared with whites. The higher the intake of animal fat, the greater the risk for advanced prostate cancer. These results indicate that diet plays a major role in why black men have a higher rate of prostate cancer and show that a reduction of fat from animal sources in the diet could lead to decreased incidence and mortality rates for prostate cancer, particularly among African- Americans. In one, a total of 29,133 male smokers ages 50 to 69 from southwestern Finland were randomly assigned to receive vitamin E (50 mg), beta-carotene (20 mg), both nutrients, or a placebo for 5 to 8 years (median 6. A 32% decrease in the incidence of prostate cancer was observed among the 14,564 subjects receiving vitamin E compared with the 14,569 not receiving it. However, in the 14,560 subjects receiving beta-carotene, prostate cancer incidence was actually 23% higher and mortality was 15% higher compared with the 14,573 not receiving it. Another form of vitamin E, known as gamma-tocopherol, may prove to be more important against prostate cancer than the alpha-tocopherol form, which has been used in virtually all the vitamin E research. Eight different compounds—four tocopherols and four tocotrienols—make up the vitamin E family. They have some functions that are similar and other functions that are completely different. Alpha-tocopherol became synonymous with vitamin E for two main reasons: (1) of the eight, it is the most abundant in the human body, and (2) it is by far the most effective of the eight for what was originally thought of as vitamin E’s main function—to support reproduction. Our blood and tissue contain much more alpha-tocopherol than gamma-tocopherol despite the fact that in the typical American diet we consume twice as much gamma-tocopherol as alpha. The reason is that the liver is able to identify the alpha-tocopherol as it is absorbed from the gut and bind it to a special protein, called the alpha-tocopherol transfer protein. It recognizes the alpha- tocopherol and preferentially puts more of it in lipoproteins—proteins that carry fat and cholesterol (e. This compound and other metabolites may act to better protect the prostate from oxidative damage as well as promote apoptosis (programmed cell death), which helps prevent cells from becoming cancerous. In one study, 117 men who developed prostate cancer and 233 matched control subjects had toenail and plasma samples assayed for selenium, alpha-tocopherol, and gamma-tocopherol. For gamma-tocopherol, men with the highest levels had a ﬁvefold reduction in the risk of developing prostate cancer compared with men with the lowest levels. The association between selenium and prostate cancer risk was in the protective direction. Statistically signiﬁcant protective associations for high levels of selenium and alpha-tocopherol were observed only when gamma-tocopherol concentrations were high as well. These results indicate that in order to achieve the greatest degree of protection, natural mixed tocopherols that include both alpha- and gamma-tocopherol should be used, rather than only alpha-tocopherol. Natural forms of vitamin E are designated d-, as in d-alpha-tocopherol, while synthetic forms are dl-, as in dl-alpha-tocopherol. The preﬁxes d- and l- refer to two versions of the vitamin E molecule that are, in effect, mirror images of each other, the way your right hand is a mirror image of your left. Although the synthetic form has antioxidant activity, it may actually inhibit the natural form from entering cell membranes. Therefore, natural vitamin E (d-alpha-tocopherol) has greater beneﬁt than the synthetic form (dl-alpha- tocopherol). Selenium Like vitamin E, selenium has also shown beneﬁt in preventing prostate cancer in some studies. A 10- year cancer prevention trial found that selenium supplementation appears to signiﬁcantly lower the incidence of not only prostate cancer but also lung and colon cancers in people with a history of skin cancer. The results of the study were exciting to researchers because they showed the cancer prevention potential of simply adding a nutritional supplement to a normal diet. Participants in the randomized, double-blind study took either 200 mcg of selenium per day or a placebo for four and a half years and were followed for more than six additional years. Total cancer incidence was signiﬁcantly lower in the selenium group than in the placebo group (77 cases vs. While the study was planned to last 12 years, it was terminated after 7 years because no effect on the risk of prostate cancer in these relatively healthy men could be demonstrated by selenium, vitamin E, or the combination at the doses and formulations used in the study. However, our feeling is that the researchers may have been looking at the wrong form of tocopherol (see the discussion above about gamma- tocopherol). Also, other trials studying high-dose vitamin E for disease prevention have shown no beneﬁt either. It may be that when taken at such high dosages, vitamin E loses its preventive effects. In the absence of companion antioxidants vitamin E may become a free radical itself or be unable to perform its function (see the discussion of lycopene below). The fact that selenium was ineffective in preventing prostate cancer could be due to the subjects’ having sufficient levels of selenium before the trial started. Lycopene One of the most important anticancer nutrients, especially for the prostate, is lycopene—a carotene that provides the red color in tomato products. Lycopene is one of the major carotenes in the diet of North Americans and Europeans. More than 80% of lycopene consumed in the United States is derived from tomato products, although apricots, papaya, pink grapefruit, guava, and watermelon also contribute to dietary intake.

Because the clinical signs of ill- ness in birds are frequently subtle, clinical chemis- tries are necessary to evaluate cellular changes. Properly evaluating a biochemical profile requires knowledge of the diagnostic sensitivities and specifi- cities of tests, correct intervals for a specific test in a given species and a list of diseases that can induce 11 the observed changes. Adding clinical pathology data to the anamnesis and physical examination findings is important for diag- nosing most organopathies. There is a need for fur- ther documentation of the clinical and pathologic changes induced by specific diseases of all avian organ systems. Many disease reports based on postmor- tem findings frequently lack clinicopathologic data that would be of value to the clinician. With many diseases, a clinician will be able to dem- onstrate disruption of functional integrity of an or- gan by means of associated clinicopathologic changes. Supportive therapy, aimed at reestablishing Manfred Hochleithner homeostasis, is often lifesaving and enables the body to restore normal organ function. Sometimes a cause for the organ dysfunction can be found for which a specific treatment can be given. Only when distinct diseases can be diagnosed clinically will it be possible to rationally evaluate the effects of a specific therapy.

Groeneveld Department of Intensive Care Medicine, Erasmus Medical Centre, Doctor Molewaterplein 50-60 , Rotterdam , The Netherlands e-mail: a. Renal blood ﬂow has been estimated by a wide variety of techniques including renal vein thermodilution and Doppler ultrasound [7 – 10]. The most easily applied ultrasound technique, Doppler renal resistive index, provides the pulsatility or resis- tance index in renal arteries and measures renal vascular resistance rather than abso- lute blood ﬂow . Phase contrast-enhanced magnetic resonance imaging is another method , but cannot be applied at the bedside. In experimental studies, renal blood ﬂow has also been assessed with the help of microspheres and ﬂow probes around the renal artery, while the renal microcircu- lation has been studied using visualizing techniques [13, 14 ]. In a recent review, renal blood ﬂow during sepsis was either preserved or increased in one-third of the studies included and cardiac output seemed a direct determinant of renal blood ﬂow . However, even in the case of a normal or elevated cardiac output and in the absence of a severe fall in blood pressure, reduction in glomerular ﬁltration may occur as a result of renal vasoconstriction or inﬂammatory responses . During a fall in renal perfusion, glomerular ﬁltration is normally better autoregu- lated than renal blood ﬂow, due to a rise in tone of the efferent over the afferent glomerular arterioles, resulting in a rise in ﬁltration fraction (i. However, regardless of absolute blood ﬂow, ﬁltration fraction in sepsis is usually low, probably due to a fall in efferent over afferent arteriolar tone . The unique microvascular architecture of the kidney shows a network with high capillary density within the cortex to ensure ﬁltration function and poor capillary density in the medulla organized serially to facilitate osmotic gradient generation for urine concentration . A consequence of this architecture is that an oxygen gradient exists between the cortex and the inner medulla from around 70 mmHg in the cortex to <20 mmHg in the inner medulla. The low oxygen tension in the medulla results from physiological oxygen shunting within the kidney, low regional medullary blood ﬂow and high oxygen consumption within the medulla for tubular function . The combination of low oxygen delivery and high oxygen demand puts the medulla and thus the proximal tubule at high risk of ischemia. The sympathetic nervous system directly controls renal vascular tone and is activated early during sepsis. This may contribute to renal vasoconstriction, stimulation of renin release, and redistribution of renal blood ﬂow from the cortex to the medulla. Renin release is stimulated by the fall in renal perfusion and is also inﬂuenced by prostaglandins, the sympathetic nervous system, and the kalli- krein system. Prostaglandins interact in a complex fash- ion with other regulatory systems, since they may mediate renin secretion, reduce 42 A. Conversely, activation of the lipoxygenase pathway during sepsis yields leukotrienes having vasoconstrictive properties, which adversely interfere with the ﬁltration coefﬁcient. Endothelin is a potent renal vasoconstrictor and expression of endothelin receptors is increased during sepsis. Endothelin may constrict afferent more than efferent vessels, which decreases renal blood ﬂow and glomerular ﬁltration.
