In fact definition of depression by psychologist proven 25mg amitriptyline, recent results suggest that metabolic rates are not associated with tmax in mammals or birds after correcting for the effects of body mass using the most state-of-the-art statistical methods (de Magalhaes et al depression symptoms rage order amitriptyline 50mg otc. Nonetheless bipolar depression symptoms mania purchase amitriptyline 50 mg without prescription, there are no results in which metabolic rates are correctly adjusted for body mass that show a correlation between metabolic rates and maximum lifespan in mammals or birds depression coping skills order amitriptyline from india. Partly related to metabolic rates, a point of debate is whether hibernating species live longer than nonhibernating species. So far the results are mixed, but some results suggest hibernating animals may live longer (see, for instance, Lyman et al. On the other hand, it can be argued that spending a fraction of the year in hiding, during which time mortality is presumably low, contributes to the observed longer lifespan in hibernating animals. Independently of body mass, age at sexual maturity correlates with average and maximum adult lifespan in many taxa, including in mammals (Charnov, 1993; Prothero, 1993; de Magalhaes et al. In other words, the longer it takes for a given mammal to reach sexual maturity, the longer it will live afterwards. There are some exceptions, however, such as the male Anthechinus which is mentioned elsewhere. One hypothesis is that there is a mechanistic link between pace of development and pace of aging, as discussed in another essay. Different species could well be influenced by development in different ways: the relation (adult phase)/(total lifespan) shows a wide variation, which is in accordance with the several aging phenotypes found in nature. So development and its consequential body-plan can influence aging to different degrees. The body-plan of mammals, for instance, may place indirect constraints on adult life but this could be regarded as a by-product of development. That said, age at maturity correlates strongly with tmax in mammals which hints that common regulatory mechanisms could be involved (de Magalhaes et al. Though not as strongly, growth rates also correlate negatively with tmax; in other words, species that grow slower tend to live longer (de Magalhaes et al. On the other hand, for evolutionary reasons, development can be timed similarly to aging even if the relation between development and aging in mammals is indirect and minimal (Miller, 1999). Therefore, the causes for the relationship between developmental time and longevity remain a subject of debate, though it is clear that there is a strong correlation between them. Sequencing the genome of an organism is no longer a large-scale endeavour and the genomes of hundreds of species are currently being sequenced. This is exemplified in the sequencing of the long-lived naked mole-rat (Kim et al. The availability of multiple mammalian genomes also opens the door to try to identify gene features associated with longevity. For example, methionine residues in mitochondrially encoded proteins appear to be enriched in short-lived species (Aledo et al. Comparisons between nuclear genomes across species with different lifespans can also focus on identifying genes with patterns of evolution associated with longevity (de Magalhaes and Church, 2007). One genome-wide scan for genes associated with the evolution of longevity in mammals found evidence that proteins involved in protein degradation, a process associated with aging, are under selection in lineages where longevity increased (Li and de Magalhaes, 2012). Given the explosion of genomic data, these approaches are bound to become more powerful and reveal specific genes and patterns associated with longevity. To facilitate comparative studies of aging, including in genomics, our lab has developed the AnAge database which features thousands of longevity records for animals (reviewed in de Magalhaes et al. As discussed elsewhere, I think this shift from comparing physiological traits into digital biology will have a major impact in furthering our knowledge of mechanisms of aging. The Evolutionary Theory of Aging Senescence has no function-it is the subversion of function. After all, how could evolution favor a process that, as happens in most animals, gradually increases mortality and decreases reproductive capacityfi This essay presents and discusses the most important evolutionary models for how aging may have evolved. Sections Classical Evolutionary Theories of Aging Life History Theory Empirical Evidence For and Against the Evolutionary Theory of Aging the Unique Evolution of Mammalian Aging A Few Reading Suggestions on Evolutionary Biology Keywords: ageing, biogerontology, evolutionary biology, genetic dustbin, genotype, immortal germplasm Classical Evolutionary Theories of Aging Although the oldest written argument on the evolution of aging is the work of Russel Wallace (reviewed in Rose, 1991), the problem of how aging evolved was first debated by August Weismann (Weismann, 1891). Later, Weismann dropped this concept and instead suggested that aging evolved because organisms that segregate germ and soma must invest additional resources to reproduce instead of maintaining the soma, and this renunciation of the soma results in aging. The disposable soma theory predicts that aging occurs due to the accumulation of damage during life and that multiple defensive or repair mechanisms contribute to aging (Kirkwood and Austad, 2000). But the two key concepts that mark the evolutionary theory of aging came before that. Drawing on the theories from Weismann and others, like evolutionary biologists Fisher and Haldane, Peter Medawar developed one of such key ideas. The basic observation is that the force of natural selection declines with age (Medawar, 1952). There is little evolutionary advantage in having beneficial genes at age 10 because only a small fraction (+/3%) of the population will reach that age. On the contrary, genes that are beneficial at age 1 will be strongly selected for by evolution. Following the same reasoning, a gene that kills organisms at age 20 will have little impact on organisms bearing it since very few (+/0. In other words, the greatest contribution to create a new generation comes from young, not 23 old organisms and so the power of natural selection fades with age, making it possible for hazardous late-acting genes to exist (reviewed in Hamilton, 1966; Rose, 1991; Charlesworth, 1993 & 2000). Figure 1: Survival curve showing the percentage of organisms alive at a given age for a hypothetical population assuming a constant mortality rate across the entire lifespan-i. Since natural selection is weaker at later ages, as demonstrated by Medawar, then perhaps some genes are beneficial at earlier ages but harmful at later ages. For example, and using the population of Figure 1, a gene that increases survival to reproductive age or reproductive output will be favored by natural selection, even if it decreases the changes of dying at age, say, 10. Hence, harmful late-acting genes can remain in a population if they have a benefitial effect early in life-e. Therefore, the evolutionary theory of aging proposes two models for how aging can evolve. At present, both theories are widely accepted and they are not mutually exclusive (Gavrilov and Gavrilova, 2002). Life History Theory the evolutionary theory of aging is actually part of a broader theoretical framework called life history theory. Life history studies the changes organisms undergo from conception to death, but focuses particularly on the schedule of reproduction and survival (Stearns, 1992; Charnov, 1993). One life history model useful for gerontologists is the concept of r and K selection that was formally proposed by Robert MacArthur and Edward Wilson (MacArthur and Wilson, 1967; Pianka, 1970; Austad, 1997b). Even though the r and K selection model is widely recognized as a simplification, it can be useful to interpret certain life history events. In brief, r-selection is the density-independent 24 component of natural selection, which in practice refers to reproductive rate, while K-selection is density dependent, referring to the biggest population resources can sustain. Organisms in hazardous environments will maximize reproduction and thus be r-selected while organisms in non-hazardous environments will maximize their performance under crowded conditions and thus be K-selected. Therefore, r-selection will favor rapid development, small body sizes, and a short lifespan while Kselection will favor delayed development, larger body sizes, and a longer lifespan (Austad, 1997b). For instance, humans, whales, or elephants are K-selected while mice and voles are r-selected. If we consider the wide range of lifespans among animals (including mammals), as well as factors correlating with longevity, r and K selection provide a useful model to begin understanding such variation. Empirical Evidence For and Against the Evolutionary Theory of Aging the evolutionary theory of aging is supported by abundant experimental evidence (reviewed in Rose, 1991). In two classical experiments, researchers were able to delay aging in Drosophila by only allowing older flies to reproduce (Luckinbill and Clare, 1985; Rose, 1989 & 1991). This way, the force of natural selection would no longer decrease with age and, as predicted by the theory, lifespan was extended and aging delayed. A more recent experiment revealed that selection for longevity also affected reproductive effort, supporting the antagonistic pleiotropy theory (Hunt et al. Also in accordance with the theory, Steven Austad observed that opossums, a North American marsupial, living in a predator-free island reproduced later than animals of the same species on the more hazardous mainland. As determined by collagen elasticity, these animals appeared to age slower than the continental opossum (Austad, 1988; Austad, 1997a).

Legionellais an important pathogen in health-care acquired (nosocomial) pneumonia depression you have to flee buy amitriptyline now, particularly inimmunocompromisedpatients depression definition weather purchase 25 mg amitriptyline free shipping. Although Legionella is a wellrecognized problem in developed nations depression zoloft dosage purchase amitriptyline 50mg, data are scarce from developing countries great depression definition us history order generic amitriptyline line. Since risk environments and susceptible populations are found worldwide, it is likely that the problem of Legionella is under-appreciated in developing countries. Water is the major natural reservoir for legionellae, and the bacteria are found worldwide in many different natural and artifcial aquatic environments and ranges of environmental conditions, such as cooling towers; water systems in hotels, homes, ships and factories; respiratory therapy equipment; fountains; misting devices; and spa pools. The fact that legionellae are found in hot-water tanks or thermally polluted rivers emphasizes that water temperature is a crucial factor in the colonization of water distribution systems. The presence of bioflms is important for Legionella survival and growth in water systems. Distributed water is likely to contain some microorganisms, including legionellae. It is therefore reasonable to assume that all systems that use water could be seeded with microorganisms during construction, repair and maintenance, even if the water is treated. Risk factors that can promote the proliferation of legionellae include temperature, water quality, design, material used in construction and the presence of biofilms. The focus of attention in managing legionellae risks should be on preventing both proliferation and exposure. Therefore, Chapter 4 suggests control measures ranging from source water quality and treatment of source water to design of systems to prevent stagnation and control of temperature to minimise proliferation. Chapter 5 discusses the risk factors and management of cooling towers and evaporative condensers. Globally, the primary legionellae associated with outbreaks of disease from these systems appear to be L. The major risk factor for legionellae proliferation appears to be neglect or insufficient maintenance. Cooling towers and evaporative condensers are generally designed to maximize operational performance of a thermal system; however, Chapter 5 spells out the importance of an effective water treatment programme in controlling legionellae proliferation. Such a programme has multiple benefits, in that it provides for more efficient operation from reduced fouling and a longer system life from reduced corrosion, while ensuring safer operation of the system due to reduced risk of legionellosis. Maintenance of properly treated cooling systems is also an essential element in reducing legionellae risks in these environments. Initially, cooling towers were thought to be the main source of legionellae in health-care facilities, but many cases have been associated with piped hot and cold-water distribution systems. Preventive and control measures follow the same procedures identified for other buildings; for example, they involve removing dead and blind ends, maintaining elevated temperatures in the hot-water system, and periodic disinfection and permanent chlorination of the cold-water system. Chapter 7 also covers ships, which, like hotels, have complex water systems, and are diffcult to link to outbreaks or cases because passengers have usually dispersed before developing symptoms. Ships also present particular challenges, as they are closed environments that may increase the opportunity for transmission of airborne infection. Hot tubs are a particular risk, due to the warm water temperature (optimal for the growth of legionellae), high bather density, conditions that increase the risk of nutrients for bacterial growth, areas of pipework that do not receive disinfection from the pool water or hold stagnant water, and the potential to inhale aerosols at a short distance from the water surface. Design, installation, management and maintenance of these water systems must be undertaken with control of microbial growth in mind. Disinfection, cleaning, monitoring and regular service and maintenance are key factors in controlling Legionella. The chapter provides information on surveillance systems; it also gives guidance on policies and practice for outbreak management, and on institutional roles and responsibilities when an outbreak control team is convened. Chapter 10 considers regulatory aspects of controlling Legionella in water systems and preventing legionellosis. Disease notifcation systems provide the basis for initiating investigations, identifying sources of infection, issuing public advice and limiting the scale and recurrence of outbreaks. Notifcation and investigation systems can be incorporated within regulations, which generally have a number of common features. The chapter also gives guidance on designing new regulations, emphasizing the key features that need to be considered, such as managerial responsibilities; registration and notifcation; system assessment and design; operational monitoring and verifcation; documentation of management plans and record keeping; and surveillance and audit. It also covers inclusion of specifc regulations to deal with responses to outbreaks. Accurate diagnosis of Legionella is important, because timely and appropriate therapy is the key to improving patient outcomes. Legionellosis emerged because of human alteration of the environment, since Legionella species are found in aquatic environments, and thrive in warm water and warm, damp places, such as cooling towers. About half of patients develop pus-forming sputum, and about one third develop blood-streaked sputum or cough up blood (haemoptysis). Fever is present in almost all cases, and fever associated with chills usually develops within the frst day (see references for Table 1. Almost half of patients suffer from disorders related to the nervous system, such as confusion, delirium, depression, disorientation and hallucinations. Physical examination may reveal fne or coarse tremors of the extremities, hyperactive refexes, absence of deep tendon refexes, and signs of cerebral dysfunction. Radiological changes are visible from the third day after disease onset, usually beginning as an accumulation of fuid in part of the lung, which can progress to the other lobes, forming a mass or nodule. Diffuse accumulation of fuid occurs in the lungs of about one quarter of patients.
