What does it mean that lynchings were relatively rare and that they fell precipitously over time treatment bulging disc buy 1000 mg amoxicillin free shipping, even in the face of a boom in Klan membershipfi If a black person violated the accepted code of behavior treatment trends purchase amoxicillin 1000mg overnight delivery, whether by talking back to a trolley driver or daring to try to vote medications ok for pregnancy purchase amoxicillin toronto, he knew he might well be punished medications adhd buy generic amoxicillin line, perhaps by death treatment plan goals and objectives safe 250 mg amoxicillin. One or two lynchings went a long way toward inducing docility among even a large group of people medicine for uti 500mg amoxicillin with amex, for people respond strongly to strong incentives. That their fraternity engaged in quasi-religious chanting and oath taking and hosanna hailing, all of it top secret, made it that much more appealing. Kennedy also found the Klan to be a slick money-making operation, at least for those near the top of the organization. Klan leaders had any number of revenue sources: thousands of dues-paying rank-and-file members; business owners who hired the Klan to scare off the unions or who paid the Klan protection money; Klan rallies that generated huge cash donations; even the occasional gunrunning or moonshine operation. After just a few weeks inside the Klan, Kennedy was eager to hurt it any way he could. When he heard about Klan plans for a union-busting rally, he fed the information to a union friend. He passed along Klan information to the assistant attorney general of Georgia, an established Klan buster. The Klan was so entrenched and broad-based that Kennedy felt as if he were tossing pebbles at a giant. Kennedy was supremely frustrated, and out of this frustration was born a stroke of brilliance. He had noticed one day a group of young boys playing some kind of spy game in which they exchanged silly secret passwords. Superman had spent years fighting Hitler and Mussolini and Hirohito, but with the war over, he was in need of fresh villains. He spelled out the Klan hierarchy as it proceeded from the local to the national level: an Exalted Cyclops and his twelve Terrors; a Great Titan and his twelve Furies; a Grand Dragon and his nine Hydras; and the Imperial Wizard and his fifteen Genii. And Kennedy told the producers the current passwords, agenda, and gossip emanating from his own Klan chapter, Nathan Bedford Forrest Klavern No. The Grand Dragon tried to run a normal meeting but the rank and file shouted him down. When I asked them what they were doing, they said they were playing a new kind of cops and robbers called Superman against the Klan. Instead of roping in millions of members as it had just a generation earlier, the Klan lost momentum and began to founder. Nor had there been any radical changes among insurance companies, insurance brokers, or the people who buy term life insurance. Shopping around for the cheapest policy, a process that had been convoluted and time-consuming, was suddenly made simple. With customers able to instantaneously find the cheapest policy, the more expensive companies had no choice but to lower their prices. The Klan trafficked in secret information whose secrecy engendered fear, while insurance prices were less a secret than a set of facts dispensed in a way that made comparisons difficult. Information is so powerful that the assumption of information, even if the information does not actually exist, can have a sobering effect. The day that a car is driven off the lot is the worst day in its life, for it instantly loses as much as a quarter of its value. A new car that was bought for $20,000 cannot be resold for more than perhaps $15,000. Because the only person who might logically want to resell a brand-new car is someone who found the car to be a lemon. By then, the suspicion of lemonness will have faded; by then, some people will be selling their perfectly good year-old cars, and the lemon can blend in with them, likely selling for more than it is truly worth. It is common for one party to a transaction to have better information than another party. We accept as a verity of capitalism that someone (usually an expert) knows more than someone else (usually a consumer). But information asymmetries everywhere have in fact been mortally wounded by the Internet. As a medium, the Internet is brilliantly efficient at shifting information from the hands of those who have it into the hands of those who do not. Often, as in the case of term life insurance prices, the information existed but in a woefully scattered way. Later, however, in the cool-headed calm of your home, you can use the Internet to find out exactly how much the dealer paid the manufacturer for that car. The Internet, powerful as it is, has hardly slain the beast that is information asymmetry. The crimes committed by Enron included hidden partnerships, disguised debt, and the manipulation of energy markets. Henry Blodget of Merrill Lynch and Jack Grubman of Salomon Smith Barney wrote glowing research reports of companies they knew to be junk. Frank Quattrone of Credit Suisse First Boston covered up an investigation into how his company dished out shares of hot initial public offerings. Sam Waksal dumped his ImClone stock when he got early word of a damaging report from the Food and Drug Administration; his friend Martha Stewart also dumped her shares, then lied about the reason. WorldCom and Global Crossing fabricated billions of dollars in revenues to pump up their stock prices. One group of mutual fund companies let preferred customers trade at preferred prices, and another group was charged with hiding management fees. Though extraordinarily diverse, these crimes all have a common trait: they were sins of information. Most of them involved an expert, or a gang of experts, promoting false information or hiding true information; in each case the experts were trying to keep the information asymmetry as asymmetrical as possible. Consider the Enron tapes, the secretly recorded conversations of Enron employees that surfaced after the company imploded. During a phone conversation on August 5, 2000, two traders chatted about how a wildfire in California would allow Enron to jack up its electricity prices. Fear that your children will find you dead on the bathroom floor of a heart attack if you do not have angioplasty surgery. Fear that a cheap casket will expose your grandmother to a terrible underground fate. Fear that a $25,000 car will crumple like a toy in an accident, whereas a $50,000 car will wrap your loved ones in a cocoon of impregnable steel. The fear created by commercial experts may not quite rival the fear created by terrorists like the Ku Klux Klan, but the principle is the same. Aside from the fact that selling a house is typically the largest financial transaction in your life, and that you probably have scant experience in real estate, and that you may have an enormous emotional attachment to your house, there are at least two pressing fears: that you will sell the house for far less than it is worth and that you will not be able to sell it at all. In the first case, you fear setting the price too low; in the second, you fear setting it too high. She is the one with all the information: the inventory of similar houses, the recent sales trends, the tremors of the mortgage market, perhaps even a lead on an interested buyer. You feel fortunate to have such a knowledgeable expert as an ally in this most confounding enterprise. Think back to the study cited at the beginning of this book, which measured the difference between the sale prices of homes that belonged to real-estate agents themselves and the houses they sold for their clients. So her job is to convince you that a $300,000 offer is in fact a very good offer, even a generous one, and that only a fool would refuse it. As soon as I signed the purchase contract, he asked me if I would need an agent to sell my previous Stanford house.

Vaccinations for infectious diseases are discribed, as prevention for endoand ectoparasites. A possible advice could be to house negative and positive individuals separately, instead of using vaccination (Miller, 2011). They should be readministered every 2-4 weeks until the cubs are 14-16 weeks of age. Core vaccines should only be administered every one or three years thereafter (it will depend on the vaccination used) (Miller, 2011). Rabies vaccination should be firstly administered when cubs are around 6 months (they can be vaccinated at earliest 3 months). A booster should be administered every year or every three years, this will depend on the registration of the vaccine used (Miller, 2011). A Rabies booster should be administered every year or every three years (Miller, 2011). This is an example of vaccination schedule used in several institutions in Europe: Table 7: Example of vaccination schedule (Kaandorp, C. Vaccine First Booster Booster Adult Cheetah Vaccination Fel-O-Vax-5 9 12 16 Once a year Vaccine Inactivated weeks weeks weeks (Chlam) (Boehringer Ingelheim), Fevaxyn Quatrifel (Zoetis) Vaccine Inactivated Rabies (dead vaccine) Normally first Booster Repeat once a year in endemic areas vaccination possible at (or once every 3 given at 6 12 months years, depending on months vaccine registration) (earliest 3 months) Cheetahs must be vaccinated with inactivated vaccines! Regular faecal examinations should be done and action should be taken according to the results (presence or absence). However, in theory treatments should only be prescribed after positive results, to avoid creating parasite resistance (Kaandorp, C. Treatment Although treatment against endoparasites should be prescribed after positive faecal testing, many institutions have preventative protocols to treat their animals with antiparasitic drugs due to the risk of re-infection in the often highly contaminated enclosures (Kaandorp, C.

Anna Kubber-Heiss, Institute of Pathology and Forensic Veterinary Medicine, University of Veterinary Medicine, A-1210 Vienna, Austria. A delay in the necropsy procedure, especially in the central nervous system can result in significant tissue autolysis and subsequent diagnostic difficulties. In the field where many necropsies are performed, suitable electric saws are mostly unavailable. A technically simple and rapid method for spinal cord removal, requiring only a straightforward tool has been devised. No necropsy induced structural damage has been noted on histo-pathological examination. Following standard necropsy procedures and evisceration of the carcass, the brain is removed and transected from the spinal cord at the level of the foramen magnum. The spinal column is separated from the remaining carcass and the paravertebral soft tissues and muscles are removed. The spinal column is then transected at the level of the intervertebral discs into approximately 15 cm. Spinal column, cheetah, Transected at the level of the intervertebral discs into approximately 15 cm. In adult cheetahs a 250 mm long, 5-mm wide and 1 mm thick sterile, blunt metal blade is carefully inserted laterally to the spinal cord and into the spinal canal (fig. Spinal cord, cheetah, A 25-cm long, 5mm wide and 2-mm thick sterile, blunt metal blade is carefully inserted laterally of the spinal cord, into the spinal canal. The blade is moved dorsally and ventrally within the canal transecting the segmental nerves. Though not possible in all cases, it should be attempted to separate the dura mater from the epidural attachments in order to remove the spinal cord with the intact dura. Following this circumferential preparation, the spinal cord is grasped at one end with forceps and gently pulled out of the spinal canal while carefully removing persisting attachments (fig. Spinal cord, cheetah, the cord is grasped at one end with anatomic tweezers and gently pulled out of the spinal canal whilst carefully removing persisting attachments. If possible the spinal cord should be grasped by the dura mater to further reduce the possibility of artifacts. The process is repeated in each segment until the entire spinal cord has been removed. Once removed the spinal cord can be processed as required for further examination. However, this fragment should be frozen for possible viral isolation or biochemical and molecular studies. The cranial aspect of each spinal cord segment is marked with a small incision and placed in 10% buffered formalin. Small tight fitting containers, with an adequate volume of formaldehyde, help in avoiding post necropsy transport trauma to the cord. Special fixatives may be required for subsequent electron microscopy, immunocytochemistry or in-situ hybridization studies. The nervous tissue in juvenile animals contains more water and fewer lipids than in adult animals and therefore does not fix as well. The described tool is easily constructed from a flat stainless steel sheet in a simple workshop. Through variations in the size of the blunt edged blade this method can be adapted for various species and juvenile animals.

When the transport protein reaches saturation treatment bursitis purchase amoxicillin discount, the remaining vitamin C is excreted in the urine medicine song purchase amoxicillin discount. The estimated threshold for excretion is about 80 mg/d meaning that essentially no vitamin C is excreted in the urine if the daily intake is lower than the threshold (5) treatment urinary tract infection generic amoxicillin 250mg free shipping. The body pool of ascorbic acid increases up to a daily intake of approximately 100 mg (6) at which point neutrophils symptoms 5 dpo order amoxicillin 1000mg visa, monocytes symptoms 10dpo generic 650 mg amoxicillin amex, and lymphocytes become saturated (3 medications ending in lol order amoxicillin 1000 mg, 7). However, above a daily intake of about 100 mg ascorbic acid, further increases in vitamin C intake lead to gradually smaller increases in plasma vitamin C levels (9). Plasma ascorbic acid concentrations below 23 mmol/L are indicative of marginal vitamin C status (8). This level is reached with an estimated daily intake of 41 mg, but this exact value depends on body size (8). Marginal status can present as decreased antioxidant capacity, fatigue, and irritability (3). Symptoms of scurvy are observed when plasma levels are below 11 mmol/L (8) or the total body pool is below 300 mg (9). Scurvy is very uncommon, but cases have been reported even in Nordic countries (10). Prospective cohort studies One way to study the associations between vitamin C and chronic diseases is to use longitudinal population samples, or cohort studies. Unfortunately, these are not ideal for many reasons, the most important of which is that it is almost impossible to make precise estimations of vitamin C intake by using the methods available in studying large populations (mainly foodfrequency questionnaires). Another approach is to study the association of plasma ascorbic acid concentration and disease outcomes. The advantage of this approach is that plasma vitamin C measurements are more accurate and reliable than estimates of dietary vitamin C intake. The drawback to this approach is that plasma vitamin C levels refect many other dietary and lifestyle variables than just vitamin C intake from the diet. For example, consumption of fruits and vegetables correlates with plasma ascorbic acid concentration (1) but fruits and vegetables also have positive health efects that are not explained by their vitamin C content. In addition, even afer multiple adjustments a high intake of fruits and vegetables can still be associated with some unmeasured lifestyle variables that are positively related to health (11, 12). All of these studies showed that the risk for mortality and morbidity was highest in subjects with the lowest plasma concentrations. The relationship between plasma vitamin C concentration and morbidity was curvilinear in most of the above studies, that is, the largest decrease in risk (compared to , for example, the adjacent lower quartile), was observed for those between the 20th and 40th percentile. Studies with cancer mortality as the outcome have also identifed the lowest plasma ascorbic acid category as being clearly associated with increased risk (20, 26). However, in some studies (13, 14, 17, 18, 20), decreased risk for cardiovascular mortality (signifcantly diferent from the category with highest risk) was only seen in categories with higher plasma ascorbic acid concentration. The same variation was seen in studies using disease incidence as outcome: in some cases, those above the 25th percentile had similarly reduced risk ratios (22, 25), but other reports showed that the risk was still reduced at least up to the median plasma ascorbic acid concentration (21, 23, 24). However, the estimation of dietary intake (without supplements) is as difcult to assess as in observational studies. Another more principal problem is that the amount of supplemented vitamin C is ofen signifcantly higher than the assumed average and recommended intakes (27). Therefore, these studies do not provide much information about variations of intakes that are closer to what can be achieved from ordinary diets. Bjelakovic and co-workers (27) published a meta-analysis on mortality in randomized trials of antioxidant supplements for the prevention of diseases. Although Salonen and co-workers (28) reported that vitamin C slowed down atherosclerotic progression in hypercholesterolemic persons, the overall conclusion in the meta-analysis was that vitamin C alone or in combination with other antioxidants had no signifcant efect on mortality (27). In contrast, a meta-analysis of clinical trials concluded that vitamin C supplementation (median dose 500 mg/d) lowered blood pressure in both hypertensive and normotensive participants (31). However, most trials were short in duration (median 8 weeks) and the trial sizes were rather small and ranged only from 10 to 120 participants. Therefore, larger studies of longer duration are needed to get more insight into the potential blood pressure lowering efects of vitamin C supplementation. Dietary micronutrient recommendations are typically based on data on defciency symptoms (lower intake level) and on associations with, and efects on, chronic diseases such as cardiovascular disease, type 2 diabetes, cancer, and osteoporosis. In addition to chronic diseases, vitamin C has a potential efect in the prevention and treatment of the common cold. However, a meta-analysis has concluded that there is no scientifc evidence supporting a protective role of vitamin C supplementation in reducing the incidence of colds in normal populations (32). In contrast, randomized trials suggest that vitamin C supplementation might reduce the incidence of the common cold in athletes and other individuals who are under extreme physical stress (33, 34). Requirement and recommended intake Earlier Nordic recommendations (35), as well as the U. This intake would also lead to plasma ascorbic acid concentrations above 23 mmol/L (8). Based on the increased recognition of the antioxidant property of vitamin C, it has been proposed that the daily recommendations should be based on its antioxidant activity rather than on antiscorbutic activity or body pool (2). Moreover, it seems clear that the maximal antioxidant activity is reached afer higher intakes than the levels needed to prevent scurvy (3). This reasoning could obviously be challenged because it is mostly based on population studies with the limitations noted earlier in this chapter. However, the evidence might be biased due to the fact that all identifed cohort studies relied on the same data. By giving a conservative 25% allowance for the inter-individual variation, the daily recommendation is set to 75 mg. Hence, this recommendation can be seen as the meeting point of two approaches: one from population studies and the other from pharmacokinetics (the excretion of vitamin C into the urine). The pharmacokinetics of vitamin C in women appear to be similar to those in men (7). However, at daily intakes below 100 mg, women have slightly higher plasma vitamin C concentrations for a given level of intake. These data suggest that the average requirements are slightly lower in women, which might be due to their smaller body size (9). However, to ensure adequate non-haem iron absorption, the coefcient of variation for women was assumed to be double that for men, and hence the same recommendation is applied for both sexes. Smokers might need about 30 mg more vitamin C daily to reach plasma vitamin C levels comparable to non-smokers (40). The recommended intake is increased by 10 mg/d during pregnancy to cover the increased needs due to the growth of the foetus and catabolised 470 vitamin C (9). If the average milk production is 750 mL/d, up to 25 mg/d of additional vitamin C would be needed during lactation. This, then, increases the daily vitamin C recommendations during pregnancy to 85 mg/d and during lactation to 100 mg/d. The average requirements for children were extrapolated from the adult values by assuming growth factors of 1. Reasoning behind the recommendation the 2004 Nordic Nutrition Recommendation (37) was based on a mean ascorbic acid cut-of point of 32 mmol/L, which was the unweighted mean of the eight studies with mortality as the outcome. The average dietary vitamin C intake leading to this plasma ascorbic acid concentration was estimated to be 60 mg. However, the evidence for this might be biased due to the fact that all of the identifed cohort studies relied on the same data. Therefore, these data were not regarded as sufcient for raising the average requirement or the recommended intake. Upper intake levels and toxicity There is no evidence that high intakes (>1,000 mg/d) of vitamin C are carcinogenic or teratogenic (40). However, high intakes might cause diarrhoea and other gastrointestinal disturbances and possibly also increased oxalate formation and kidney stone formation in susceptible individuals.

Introduction the amount of calcium in the body at maturity is approximately 1,200 g and 1,400 g in adult women and men, respectively. Over 99% is found in teeth and bones, and the remainder is present as an easily exchangeable pool in the blood, extracellular fuid, and in all cells in the body. This free calcium plays vital roles in signal transduction both within and between cells, neuromuscular transmission, glandular secretion, and in a large number of enzymatic reactions. They contribute to the maintenance of a constant calcium concentration in the plasma by regulating the infux and efux of calcium in the intestine, bones, and kidneys. Maintenance of a constant concentration of ionised calcium is of vital importance, and calcium homeostasis is probably the most tightly regulated homeostatic mechanism in the body. Adult bone tissue undergoes continuous remodelling through resorption by osteoclasts and formation of new bone by osteoblasts. The rate of exchange of calcium between bone and the exchangeable 475 pool has been estimated to be about 700 mg/d. Bone formation exceeds bone resorption in children, and the rate of remodelling is higher in children than in adults and it is higher in trabecular bones than in cortical bones. Dietary sources and intake Milk and dairy products are main sources of calcium in the Nordic countries. Other sources of calcium are fsh and fsh products, especially when eaten with the bones intact. Physiology and metabolism In the intestine, dietary calcium is mixed with calcium in the digestive juices. From this mixture, absorption takes place mostly in the upper part of the ileum by passive difusion or by an active energy requiring process. The diference between dietary calcium and that lost in faeces is termed net absorption.
