The year 2008 marked the end of the planned extractions of wild lynxes for incorporation into the breeding population; still buy bupron sr 150 mg otc anxiety questionnaires for children, those found injured or handicapped with compromised probabilities of survival in the wild will continue to trickle into the Breeding Programme buy 150mg bupron sr with mastercard depression recipes. To provide the captive space needed to achieve the Programmes genetic goals proven bupron sr 150mg depression years after concussion, construction of two new iberian lynx breeding centers Granadilla (Extremadura) y Odelouca (Silves cheap bupron sr 150mg mastercard bipolar depression pregnancy, Portugal) is underway. An additional center in cabaeros (castille-La Mancha) is also scheduled for future construction. All breeding centers are strategically placed so they can be co-managed by administrations that commit to habitat preparation for future reintroductions. All centers considered, the captive population will be managed as a metapopulation, a genetic counterpart to the Sierra Morena and Doana free-ranging populations (Godoy et al. One of the Programmes key husbandry challenges is to strike a balance between fostering natural behaviours in captivity (hunting, territoriality, social interactions, etc. For this reason, the Breeding Programme favours naturalistic enclosures and promotes natural behaviours via environmental enrichment (Manteca, this book; Martos, this book). Some of these include obtaining regular weights by having the lynx step on a measuring scale. Such techniques are designed to avoid using invasive methods, which would stress the animals, and they also serve as a way to strengthen the trust between the animals and their keepers. Special care is taken to avoid domestication of captive lynxes, although this becomes a greater challenge in the case of hand-reared, abandoned cubs (Rivas et al. Breeding season in captivity mostly takes place throughout January and February, with most births occurring in March and April, as it is the case in the wild (Palomares et al. The actual mating period lasts between two and three days during which lynxes copulate an average of 28 times (range: 13-65; n=460 copulatory bouts in 21 pairs; Table 1). Gestation period, counted from the time of the frst copulation, ranges from 63-66 days (n=12). All parturitions that have occurred before 61 gestational days (n=4) have resulted in the birth of either dead or weak and not completely developed young, which were considered premature. Although variation between individuals is very high, most females are very consistent regarding their own timing to enter estrous and regarding the number of days they are gravid (Table 1). Labour during whelping (regarded as the time lapsed between the frst visible contractions until the delivery 63 of the last offspring) varies widely between females, with some of them delivering each young within 10-15 min intervals while others taking up to 9 hours between the delivery of each offspring (Table 1). Primiparous females have a higher rate of failure to raise their young than multiparous ones. Out of the eight females that have whelped at El Acebuche center, only two frst-time mothers Saliega and Aura managed to nurse all their young until weaning age. Two other dams Esperanza and Boj kept only one of their cubs after whelping and abandoned the rest of the offspring in their frst litter, while three other females Adelfa, Aliaga and Brisa miscarried one of their offspring and delivered the rest of the cubs prematurely during their frst gestation. This non-intrusive surveillance system has also allowed us to identify the existence of a sensitive period when iberian lynx cubs become highly competitive to the point of siblicide (Vargas et al. Spontaneous aggression erupted at 44 days of age in the frst iberian lynx litter born in captivity. The largest cub (a female) in a litter of three was killed by a brother who delivered lethal bites to the larynx and skull. Agonistic behaviour has been observed in nine of eleven subsequent iberian lynx litters of two or more cubs, with the most intensive fghting occurring around the end of the sixth and seventh post-natal weeks, respectively (Antonevich et al. This same phenomenon has been observed in the Eurasian lynx by Russian scientists at the Tcherngolovka facility who recorded aggressive behaviour in 16 of 31 litters, with deaths occurring in four cases (naidenko and Antonevich, this book). The authors indicate that the highest prevalence of agonistic behaviour in Eurasian lynx cubs occurred at 36 to 64 days of age, with the greatest frequency during the seventh post-natal week. Although siblicide in iberian lynx has not been directly observed in nature, a 1-month-old cub was found in the wild in 2003 with severe injuries compatible with bites from another cub. Sibling aggression in iberian lynx has infuenced programme husbandry as staff must be vigilant and prepared to break up aggressive bouts during the sensitive period. Because relatively little was known about the diseases affecting the iberian lynx, actions to improve our knowledge of the main diseases affecting the species was imperative. To improve the understanding of the various diseases that could potentially affect the species, the Programmes main lines of action involve the establishment of preventive disease protocols for the captive population, capacity building of veterinary staff working with in situ and ex situ populations, and conducting research on general veterinary science (Martnez et al. Research projects have helped determine the incidence and prevalence of infectious pathogens in captive and wild lynx populations (Milln, 2006; Meli et al. The results of research, protocol development, and standardization efforts, coupled with dissemination and sharing of knowledge and experience among veterinarians working in the Programme are all contributing to 65 more consistent diagnosis and treatment. Re P R o d u c t I v e P h y s I o l o g y Reproductive physiology studies and associated technologies increase the success rate of any captive-breeding programme and are important in helping with the conservation of wild felids in captivity (Wildt et al. Reproductive technologies are available for three major purposes: 1) assessing fertility and monitoring reproductive status; 2) assisting in breeding and maintenance of gene diversity; and 3) learning more about reproductive mechanisms of the endangered iberian lynx. Faecal hormone monitoring has demonstrated that females experience ovarian cycles from January through May whereas males maintain testosterone year-round (Pelican et al. But species peculiarities also have been revealed, for example, oestrogen metabolite concentrations during pregnancy are signifcantly greater than in other felid species (Pelican et al. Additionally, progestin excretion profles are unusually lengthy, largely because ovarian corpora lutea (sites of earlier ovulations) remain active much longer than in most other felids (Gritz et al. Prolonged non-pregnant luteal activity has also been described in the closely related Eurasian lynx (Lynx lynx; Jewgenow et al. Regarding male reproductive physiology, sperm traits seen in the iberian lynx are lower than those reported for some other felid species, yet higher than those reported for the Eurasian lynx and the bobcat (Gan et al. The ex situ population is also being used to explore a novel means of diagnosing pregnancy. Because all ovulating lynxes produce rising progesterone (regardless of conception), conventional hormone monitoring is not useful for identifying a gestating female (Pelican et al. However, increasing concentrations of the hormone relaxin (in blood or urine) are indicative of pregnancy in felids (Van Dorsser et al. A unique non-invasive means of collecting blood has been developed using blood-sucking Triatomine bugs (Rhodnius prolixus or Dipetalogaster maxima) placed in specially-drilled hiding holes in the lynxs cork nestbox (Voigt et al. As much as 2 ml of blood can be extracted per bug, more than adequate for the assay. Urine is captured using special collection devices distributed throughout the animals enclosure. Pregnant females express a positive relaxin signal from 32 to 56 days post-copulation of a 65-day gestation (Braun et al. The conservation of gametes will allow the Breeding Programme to extend future options without the limitation of space or the risk of disease transmission, while opening the opportunity of prolonging the possibilities of reproduction for individual animals after their death (Roldan et al. ReIntRoductIon The small size of current iberian lynx free-ranging populations renders them highly vulnerable to stochastic events. Prior to any reintroduction/translocation a detailed viability study is required (iUcn Guidelines for reintroductions: iUcn, 1998). All reintroductions and translocations must be performed using scientifc support and the iberian lynx should be no exception (calzada et al. The frst reintroduction is scheduled to take place in 2009 using wild-born individuals from the Sierra Morena population (Simn et al. Preparation for release will include maintaining animals in large preconditioning enclosures with minimal human contact and exposure to natural stimuli, including live prey. Lessons from other reintroduction programmes will be essential for the planning and implementation of the frst iberian lynx reintroduction. Education and awareness efforts should be focused on changing prevalent attitudes that contribute to habitat destruction and species extinction. One advantage enjoyed by conservation breeding programmes is their ability to gain public attention, particularly if the animal in question is charismatic and attractive to the broader public. The iberian lynx is one such case, and raising public awareness for the need for habitat conservation to guarantee survival of the species in the wild is one of the Programmes objectives. The Breeding Programme encourages, cooperates with, and supports media interest in the iberian lynx, while taking every opportunity to remind the public of the primary importance of habitat conservation. An English language version is currently in production to further expand the scope of communication and awareness efforts.
Organic personality disorder has been described discount bupron sr 150 mg mastercard depression symptoms after giving birth, particularly among the apathetic elderly bupron sr 150 mg with visa anxiety 24 hours. Distraibility and over-arousal have also been reported cheap bupron sr 150mg without prescription depression articles, sometimes leading to persistent cognitive impairment cheap 150 mg bupron sr with visa depression brain, which may continue even after the patient is euthyroid (Stern et al, 1996). Specific cognitive difficulties in hyperthyroid patient have been described, such as deterioration of memory, concentration or visuomotor speed (MacCrimmon et al. The initial symptoms in hyperthyroidism may be quite similar to anxiety disorders, but the described, unusual symptoms of anxiety may alert the clinicians (Kathol et al. Other symptoms that should alert the physicians are the preference for cold and intolerance to heat, or loss of weight coupled with increased appetite. A careful medical history and examination are mandatory in such cases and the laboratory test would usually give unequivocal answers to the diagnostic difficulties. An accelerated pulse during sleep or cognitive difficulties are also considered to suggest the diagnosis of hyperthyroidism in such cases (Hall et al. To help in the differential diagnosis some specific scales have been developed (Iacovides et al, 2000). Transient thyroid hormone elevations, usually mild, may occur in approximately 10% of psychiatric inpatients, but should not be diagnosed of hyperthyroidism. Thyroid abnormalities have also been documented in some studies in primary affective disorders (Oomen et al. Other clinical situations may mimic the thyroid condition before the laboratory results are available, such as abuse of stimulants or drug intoxications. However, the nervousness and emotional lability in hyperthyroid patients may be wrongly diagnosed as alcohol abuse or abstinence. The clinical interest derives from the fact that it has been associated with cognitive deterioration and dementia in the elderly (Kalmijn,2000;Ceresini,2009), both in cross-sectional and longitudinal studies. While the clinical and epidemiological studies reviewed support the association of hyperthyroid function with psychopathological disturbance, the causal mechanisms are not clear (Bunevicius et al. One study suggested that the active thyroid hormone (T3) influenced mental performance in healthy subjects (Kathmann et al. The individuals overestimated time intervals and increased their word fluency, but no other cognitive problems were detected. Prez-Echeverra (1985) and Lobo et al (1988) documented direct, convincing correlations between abnormal levels of thyroid hormones and psychopathology. The abnormal psychological phenomenon seemed to be directly related to the endocrine disturbance, since non-endocrine medical patients in the same ward, and with similar levels of illness severity had lower levels of psychopathology. In general, there is a good resolution of anxiety and depression with antithyroid treatment alone, unless there is previous psychiatric history (Kathol et al. Beta-blockers such as propanolol are also considered to be effective in cases of anxiety (Trzepacz et al, 1988). However, recovery may be slow and reduced psychological well-being has been reported in a considerable proportion of remitted hyperthyroidism (Prez-Echeverra, 1985). Bunevicius also reported persistent mood and anxiety symptoms in treated hyperthyroidism (Bunevicius et al. Low potency 248 Thyroid and Parathyroid Diseases New Insights into Some Old and Some New Issues neuroleptics such as haloperidol and perphenazine have been reported, including symptoms resembling thyroid storm and malignant neuroleptic syndrome. Finally, treatment of depression is recommended if psychopathological symptoms are severe or persistent. Hypothyroidism Classical symptoms of hypothyroidism include fatigue and weakness, somnolence, weight gain, constipation and cold intolerance. However, other common symptoms may suggest primary psychiatric disease and include lethargy, progressive slowing, diminished initiative and impaired concentration and memory. Congenital hypothyroidism is also well known, and usually occurs as the consequence of thyroid dysgenesis, and more rarely as the result of inherited defects in the synthesis of thyroid hormone. This syndrome is characterized by mental retardation, aside from the classical somatic and neurological signs. Screening programs for hypothyroidism at birth are now mandatory to prevent this severe condition. The most frequent cause of adult hypothyroidism is Hashimotos thyroiditis or autoimmune thyroiditis. Treatment of Graves disease with radioactive iodine may also lead to hypothyroidism, but an important iatrogenic cause in psychiatric patients is the side effect of lithium, particularly in vulnerable individuals such as women or rapid cyclers. There are no good prevalence studies of psychiatric disturbance in hypothyroid patients, but the main psychiatric syndromes have been described in case reports and/or clinical samples. The depressive syndromes may mimic primary affective disorder, particularly in old women, and may need the checking of hormonal levels for the differential diagnosis. Marked irritability and labiliy of mood may alert to the presence of atypical syndromes, suggesting an organic condition. Thyroid replacement is required in such cases and is usually effective, although depression persists in a proportion of patients A special emphasis should be placed in subclinical hypothyroidism. The relevance of subclinical hypothyroidism is derived from the fact that depression is common and may severely affect quality of life. The same authors have recently reported that depression in such patients is more frequent than among patients with overt hyperthyroidism (Chueire et al. Furthermore, they conclude that subclinical hypothyroidism increases more than four times the risk of depression, and highlight the relevance of thyroid screening tests in Thyroid and Parathyroid Diseases and Psychiatric Disturbance 249 the elderly. It has been suggested that subclinical hypothyroidism is rather common in the general population, particularly in the adult and elderly women, but may go undetected and untreated. Delirium has been observed in approximately 10% of severe cases of hypothyroidism, and organic delusional syndromes have been documented in some case reports. Some authors have called Hashimoto`s encephalopathy the clinical picture of delirium with focal neurological signs and seizures. It has been considered to be associated with high levels of serum antithyroid antibodies, but the psychopathological symptoms probably overlap with delirium of different etiologies (Schiess & Pardo, 2008). Memory deterioration is common, but may be accompanied by impairment of other cognitive functions. While some cognitive difficulties may be associated with the depressive syndromes, some authors have reported independent, cognitive difficulties (Burmeister et al. Mild hypothyroidism has also been associated with mild cognitive difficulties (Bunevicius et al, 1999; Miller et al, 2007). While most cases of cognitive disturbance improve with hormonal treatment, some studies reported negative results (Walsh et al. Hypothyroidism used to be considered one example of reversible dementia with appropriate hormonal treatment (Cummings et al. However, most authors doubt about its effectiveness in well established cases of dementia (Clarnette & Patterson, 1994; Lobo et al. Present knowledge about the effects of thyroid hormones in the central nervous system suggests the critical influence in brain development, and probably a direct role in adult brain homeostasis. However, both the biochemical mechanisms and the physiological relevance are poorly understood. Even minor changes in thyroid hormone may induce important affective changes (Bauer et al. However, the connections between this hormone and primary affective disorder remain controversial. Some authors conclude that depressed patients are basically euthyroid (Baumgartner, 1993). Special consideration merit the cases of hypothyroidism seen in 10% of patients treated with lithium. Disregulation in the hypothalamic-pituitary-thyroid axis is commonly linked to primary affective disorders (Hendrick, 1998; Engum et al. While these findings support the connection between thyroid disorder and primary affective disorder (Stipcevic et al.

The requirement for vitamin C for adults is well defined but they have not been uniform across different cul tures, so their need has been defined as culture-specific. Some epidemiological data mentioned its usefulness in reducing cold with increasing consumption of foods rich in vitamin, so people sometimes ingest an overdose of it. In most reports mention that discrete increases in blood levels of this vitamin reduces the risk of death in all conditions. Antioxidants play important roles in cellular function and have been implicated in processes associated with aging, including vascular, inflammatory damage and cancer. History Since the nineteenth and early twentieth century research on these compounds led to the discovery of vitamins. Since 1901, a publication of Wildiers first described the stimulating4 effect of small amounts of organic material in the growth of yeast; this effect was the subject of many publications and only after several years was universally accepted. Wilders gave the name "bios" to the substance or substances causing increased growth of yeast. Definition Vitamin C is defined as hexuronic acid, cevitminic acid or xiloascrbic acid. The term vita min C is generally used to describe all these compounds, although the representative of which is ascorbic acid. Structure, formula and chemical characteristics Ascorbic acid is the enolic form of one -ketolactone. Ascorbic acid solution is easily oxi dized to the diketo form referred to as dehydroascorbic acid, which can easily be converted into oxalic acid, diketogulonic acid or threonic acid. Physical and chemical properties Ascorbic acid contains several structural elements that contribute to their chemical behavior: the structure of the lactones and two enolic hydroxyl groups and a primary and secondary alcohol group. Enediol structure motivates their antioxidant properties, as can be oxidized easily enediols to diketones. Ascorbic acid forms two bonds intermolecular hydrogen bonds (shown in red in the figure) that contribute substantially to the stability and with it the chemical qualities of the structure endiol. Hydrogen bridges formed by ascorbic acid Ascorbic acid is rapidly interconvert in two unstable diketone tautomers by proton transfer, though it is most stable in the enol form. The proton of the enol is lost, and again acquired by the electrons from the double bond to produce a diketone. Vitamers or vitameric forms The vitamer of a particular vitamin is any chemical compound which generally has the same molecular structure and each shows a different vitamin activity in a biological system which is deficient of the vitamin. The vitamin activity of multiple vitamers is due to the ability (sometimes limited) of the body to convert one or many vitamers in another vitamer for the same enzymatic cofactor which is active in the body as the most important form of the vitamin. As part of the defini tion of the vitamin, the body can not completely synthesize an optimal amount of vitamin activity of foodstuffs simple, without a certain minimum amount of vitamer as base.
