The purpose of this study was the investigation of several transport systems expressed at the BBB. The identification and functional characterization of such transport systems is essential to provide a basis for strategies to regulate drug disposition into the brain. Immortalized rat brain endothelial cells (RBE4 cells) have been used in this study as an in vitro model of the BBB. The present study has shown that the RBE4 cells are a suitable model of the BBB for transporter studies. These cells do express the amino acid transport systems L and y+, which are known to be present at the BBB. The uptake of L-tryptophan, a neutral amino acid transported by system L, exhibited a half saturation constant (Kt) of 31 µM and a maximal velocity rate (Vmax) of about 1 nmol/mg/min in RBE4 cells. The kinetic constants of the L-arginine uptake, representing system y+ transport activity, into RBE4 cells were determined with a Kt value of about 55 µM and a Vmax of 0.56 nmol/mg/min. Furthermore the expression of two sodium dependent transporters, the 5-HT transporter (SERT) and the organic cation/carnitine transporter OCTN2, was shown at the RBE4 cells. Uptake studies with radiolabeled 5-HT exhibited a saturable, sodium dependent transport at RBE4 cells with a Kt value of about 0.40 µM and a Vmax of about 52 fmol/mg/min. L-carnitine and TEA (tetraethylammonium) are known to be transported by the OCTN2 transporter. The uptake of L-carnitine into RBE4 cells was shown to be sodium dependent and saturable with a Kt value of 54 µM and a maximal velocity of about 3.6 pmol/mg/min. In contrast, the organic cation TEA follows a sodium independent uptake mechanism at RBE4 cells. Also a sodium independent choline uptake into the cells was discovered but the molecular identity remained unknown. This saturable choline transport exhibited a Kt value of about 22 µM and a maximal velocity of about 52 pmol/mg/min.

Full textAbstract:
Feral and fearful cats and kittens in animal shelters are not likely to be adopted as companion animals because they emit fearful or aggressive behaviors in the presence of humans. The purpose of the fearful to friendly (F2F) research was to investigate a shaping procedure to increase friendly behaviors of feral and fearful domestic cats and kittens with the goal of achieving animal shelters’ adoptability criteria. The results showed the F2F procedure was a safe and very effective procedure to quickly tame feral kittens deemed unadoptable. The day after implementing F2F, three out of four kittens approached me and accepted petting and holding without any additional training.

Full textAbstract:
During recent years of schizophrenia research, many etiologies have been emphasized, some of them implicating infectious and autoimmune diseases. Many different infectious agents have been examined, but the root seems to stem from the secondary autoimmune deregulation, which can be caused by different infectious agents. Among the effects that autoimmune deregulation has on the body, one prominent effect is on the brain, resulting in either severe or mild encephalitis. The mild encephalitis that has been implicated as one of the causes of schizophrenia-spectrum disorders has been associated with different pathogens, many of which can be transmitted by the household cat. Thus in the present research we have used the schizotypy personality construct model as an analog for schizophrenia spectrum disorders, and the relationship between current schizotypy and childhood household cat interactions were examined. An online questionnaire was completed by 356 undergraduate students and assessed the current schizotypy using the Schizotypal Personality Questionnaire Brief Revised (SPQ-BR), as well as questions about cat ownership and cat bites (puncturing skin) prior to age 13. While no significant relationship was found between childhood cat ownership and current schizotypy, individuals endorsing a cat bite prior to age 13 (N = 66) reported a significantly higher level of current overall schizotypy, which was largely driven by the Disorganized factor of the SPQ-BR.. This relationship should be explored further by examining the antibodies and sera of individuals with the schizophrenia spectrum disorder.B.S.

Sensory neocortex contains a significant number of inhibitory neurons that use gamma-aminobutyric acid (GABA) as their neurotransmitter. Functional roles for these neurons have been identified in physiological studies. For example, in primary somatosensory cortex (SI), blockade of GABAa receptors with bicuculline leads to expansion of receptive fields (RFs). The magnitude of RF enlargement varies between SIpopulations of GABAergic neurons were identified by labeling specific calcium binding proteins.

CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICOA presente dissertação pretende descrever e analisar as potencialidades futuras oferecidas por sistemas CATV operando serviços de comunicação iterativos e de faixa larga. Neste contexto, visando determinar as configurações mais adequadas para a parte óptica da rede, são analisadas diversas alternativas de implementação envolvendo os dispositivos constituintes básicos: laser, modulador externo, EDFA, e fibra, sendo neste último caso, tanto a utilização de fibra padrão quanto a de dispersão deslocada. Dentro do espírito de serviços de faixa larga, implementa- se em laboratório um sistema WDM com duas portadoras ópticas. A primeira, em 1310 nm, é modulada em intensidade com 2.48 Gbits/s. a segunda, em 1550nm, é modulada em AM- VSB. As interferências mútuas são então medidas e confrontadas com resultados previstos teoricamente, validando este último modelo. A formulação teórica permite então prever a deterioração mutua em um WDM com duas portadoras digitais em 2.48Gbit/s. Os resultados obtidos sugerem a viabilidade deste último arranjo para portar vídeo digitalizado. Dando seqüência, são apresentadas novas soluções para compressão de vídeo, técnicas de modulação e tecnologias de transporte. Finalmente, os resultados obtidos anteriormente, tanto os práticos quanto os teóricos e os simulados, são usados para propor novas arquiteturas de redes de CATV explicitando as sugestões para o caso de redes HFC (preferencialmente destinado a operadoras de TV a cabo) e também para configurações FTTC, estas últimas, preferencialmente destinadas às operadoras telefônicas.
This work is aiming at discussing the future possibilities the CATV systems are likely to offer, concerning iterative communications and broadband services. In what concerns the system optical section, a search is carried out in order to reach suitable arrangements and configurations concerning the basic used components, namely: laser, external modulator, EDFA and the optical fiber. Both standard and dispersion shifted fiber utilization are considered. Considering broadband utilization, a practical experiment is carried out. A two carrier WDM system is tested in the laboratory. The first carrier - 1310 nm - is digitally modulated at 2.48 Gbit/s, while the second one - 1550 nm - carries an AM-VSB modulation. Crosstalk is measured and the obtained results are compared with those from a proposed theoretical model. A satisfactory agreement validates the model. Next, the same model is then used for predicting crosstalk level in another two carrier WDM, however now, with both carriers being digitally modulated at 2.48 Gbit/s. the obtained results suggest that this last arrangement is worthwhile to be used for efficiently carrying digital video. A discussion on new solutions for video compression, modulation formats and transport techniques is follwed. The work is closed with a number of new CATV network solutions being suggested. Previously obtained results and performed suggestions are used for achieving two basiv lines of applications. The first one is based on HFC arrangements, mainly conceived for cable TV operators. The second on is based on FTTH arrangements, being this last suggestion better suited for traditional telephone companies.

This dissertation study describes and presents an alternative method for delivering digital video, the MPEG-4 compression format, through the use of an analog cable network for direct viewing on television sets. The purpose of the study is to propose this technology as an alternative to the present cable network technologies in Uruguay and elsewhere in South America. Delivery standards that might be used over such a CATV network include DVB-C (digital video broadcast for cable), and IP (internet protocol) networks.
The study compares the current technologies to determine which would be the best way to provide such delivery over CATV networks. It is the argument of this study that the delivery of MPEG-4 format streaming video is no different than the delivery of any type of digital signal: in order for the signal to be delivered, it must pass through a transmission medium such as fiber-optic cable, twisted-wire pair, coaxial cable, etc.
The dissertation makes the case that MPEG-4 is a feasible alternative technology which should be considered for new CATV applications in this region. This study is from a technical point of view, when it comes to implementation there are other elements that should be taken into account.

Obesidade na clínica de felinos é um problema frequente e tornou-se motivo de grande preocupação para a medicina veterinária. A obesidade é definida como acúmulo excessivo de tecido corporal adiposo. O objetivo do presente estudo observacional prospectivo foi determinar os principais fatores de riscos relacionados ao excesso de peso em gatos com ênfase na interação tutor-gato. Para tanto, foram selecionados gatos, divididos em dois grupos, a saber: grupo dos gatos obesos (n=18) nesse grupo foram incluídos gatos com escore de condição corporal entre 8 e 9; grupo dos gatos não obesos (n=18) com escore de condição corporal 5. Foram excluídos do estudo os gatos que apresentaram outras comorbidades, além da obesidade. A pesquisa dos prováveis fatores de risco relacionados a obesidade foi realizada mediante a utilização de um questionário respondido por todos os tutores dos 36 gatos. Nenhuma das variáveis qualitativas estudadas nos aspectos demográficos dos gatos obesos e não obesos demonstrou significância, ou seja, não houve associação entre obesidade e o sexo, o status sexual, as raças e o tamanho do pelame. Assim como, nenhuma das variáveis qualitativas analisadas nos aspectos demográficos dos tutores de gatos obesos e não obesos demonstrou significância; Não houve relação entre obesidade e o sexo do tutor, ao estado civil, a profissão (inclusive os clínicos veterinários), a escolaridade e a renda média familiar dos tutores. Com relação aos aspectos antrozoológicos, contatou-se que ambos os grupos têm uma relação estreita de afeto com seus tutores, contudo a porcentagem do grau de afeto tende a ser maior no grupo obeso, apesar de não ter sido evidenciada diferença estatística. Sobre os aspectos ambientais, oito variáveis foram presumivelmente consideradas importantes na manutenção e no controle do peso dos gatos. Constatou-se que felinos do grupo não obeso costumam brincar sozinhos e com outros animais, enquanto que gatos obesos são menos interativos. Ainda, o enriquecimento ambiental, assim como o manejo alimentar com dieta úmida influenciaram na condição física desses gatos. Constatou-se que o número de felinos não obesos que recebe ração úmida é bem maior que o daqueles pacientes com excesso de peso. Finalmente, o escore de condição corporal atribuído pelos tutores de felinos com excesso de peso tende a ser subestimado quando comparado ao do profissional especializado. Os principais riscos ocasionados pelo excesso de peso identificados neste estudo foram o tipo de alimentação oferecido, principalmente dietas secas, e a inatividade física. Apesar de os aspectos antrozoológicos não demonstrarem valor estatístico, o grau de afeto tende a ser levemente superior quando se analisa valores percentuais.Feline obesity is a frequent problem and has become a major concern in veterinary medicine. Obesity is defined as excessive accumulation of body fat. The purpose of this prospective observational clinical study was to determine the main risk factors related to obesity in cats with emphasis on owner-cat interaction. Thus, the studied cats were divided into two groups: obese cats (n=18) with a body condition score between 8 and 9; and non-obese cats (n=18) with a body condition score of 5. All cats were healthy at the time of the study was conducted and cats with any other disease, besides obesity were excluded. The study of the risk factors related to obesity was performed using a questionnaire answered by all owners of the 36 cats. None of the qualitative variables in demographic aspects of obese and non-obese cats showed significance, and there was no association between obesity and gender, sexual status, race and coat size. Also, none of the qualitative variables in demographic aspects of the owners of obese cats and non-obese cats showed significance. Besides that, there was no relationship between obesity and the gender of the cat owner, marital status, profession (including veterinarians), schooling and the average family income of the owner. Regarding the antrozoological aspects, we concluded that both groups of cats a close affectionate relationship with their owners, but the percentage of the degree of affection tends to be higher in the obese group, despite there being no statistical difference. Considering the environmental aspects, eight variables were presumably important in maintaining and controlling the weight of cats. It was found that non obese cats usually play alone and with other cats, while obese cats were less interactive. Moreover, environmental enrichment as long as the moisture of the diet influenced the physical condition of these cats. Non obese cats usually had more moist food than obese cats. Finally, the body condition score given by the owners of obese cats tends to be underestimated when compared to the experts score. The main risks to the overweight findings in this study were type of food offered, especially dry diets and the physical inactivity. Also, despite the anthrozoological aspects evaluated have not shown any significance as risk factors for obesity in cats, the degree of affection between owner-cat tend to be slightly higher in obese cats group.

Full textAbstract:
Since the introduction of the lipid emulsion formulation in 1986, propofol has become established for induction as well as for maintenance of anaesthesia in veterinary practice1 including cats2;3-8. Propofol is rapidly metabolized by hepatic glucuronidation in most species and it has also been shown to undergo extrahepatic metabolism9-13, so that total body clearance may exceed liver blood flow in certain species. Because of their highly carniverous diet, cats are little exposed to antiherbivory compounds so that they have become deficient in UGP-glucuronosyltransferase (UGT)14. Consequently, a number of drugs are eliminated slowly15;16, often giving rise to prolonged half-lives of the parent drugs. Cats are therefore sensitive to the adverse effects of many drugs and toxins that are normally glucuronidated before elimination. It is therefore likely that the disposition of propofol may differ markedly from that of humans and other animal species17. Adam et al18 reported that for the cremophor propofol formulation in cats, volumes of distribution were smaller and elimination halflives were longer than those of pigs, rats and rabbits. In addition, pulmonary uptake has been demonstrated to occur in cats,19 however propofol’s pharmacokinetics have not been studied formally. The purpose of this study was to determine the pharmacokinetic behaviour of propofol after single intravenous injections. In comparison with man, the apparent central volume of distribution in domestic cats is small (0.56L.kg-1 body weight vs. 0.228L.kg-1) for the human pharmacokinetic parameter set of Marsh et al20 and the clearance (0.0086 L.kg-1.min-1 vs. 0.027 L.kg- 1.min-1) is approximately 2½ times slower in cats when compared with humans. Slow clearance should not influence recovery from anaesthesia following standard induction doses, because the early decreases in blood concentrations are predominantly due to redistribution of drug to various tissues (similar to the disposition of thiopentone which exhibits a slow total body clearance21. However it is possible that drug may accumulate within the body after prolonged infusions, resulting in delayed recovery times. This phenomenon is best described by calculating “context-sensitive” decrement-times by computer simulation22-24. Computer software♣ were used to calculate the 20%, 50% and 80% context-sensitive decrement times for the cat pharmacokinetic model. For comparative purposes, similar calculations were performed for an adult human male (weight 70 kg) using the pharmacokinetic parameter-set of Marsh et al20. Assuming that recovery from anaesthesia occurs after a 50% decrease in blood concentrations has taken place, it is apparent from the 50% context-senstive decrement-time graph that for infusions lasting up to 20 minutes (during which concentrations are kept constant), recovery can be expected to be rapid and predictable. However if infusions are administered for longer than 20 minutes, the recovery times of the “average” cat increase rapidly, reaching a plateau of 36 minutes, while recovery times of the human remain short, albeit increasing slowly. Awakening times become dramatically prolonged and unpredictable in both cats and humans if propofol concentrations are required to decrease by 80% for recovery to occur. Under these circumstances the 80% decrement time after a two-hour infusion is approximately two hours in cats and 45 minutes in humans. On the other hand, if dosing is conservative, so that blood concentrations need to decrease by only 20% for awakening to occur, then recovery times are short and predictable, being only a few minutes, regardless of the duration of the preceding infusion. These findings are in accordance with those of Pascoe et al25 who reported that cats took longer to recover after a short (30 min) infusion than after a long (150 min) infusion. In their crossover study, the propofol infusion rates were adjusted so that the cats were maintained at a light level of anaesthesia at which they responded sluggishly to pedal stimulation. It is therefore likely that propofol concentrations were kept steady and were similar during the 30-minute as well as during the 150-minute infusions. Delayed recovery has also been reported when propofol was administered to cats on consecutive days26. Conclusions and clinical relevance: We recommend that propofol infusions be administered to cats only for fairly short procedures and that for prolonged surgery, maintenance of anaesthesia should be accomplished using other drugs. In order to decrease the propofol dose, premedication and analgesic supplements should be co-administered to provide “balanced” anaesthesia. ♣ TIVA Trainer version 8, author Frank Engbers, Leiden University Medical Centre CopyrightDissertation (MMedVet)--University of Pretoria, 2009.

Full textAbstract:
Background: Hyperthyroidism has substantial effects on the circulatory system. The cardiac biomarkers NT-proBNP and troponin I (cTNI) have proven useful in identifying cats with myocardial disease but have not been as extensively investigated in hyperthyroidism.Hypothesis: Plasma NT-proBNP and cTNI concentrations are higher in cats with primary cardiac disease than in cats with hyperthyroidism and higher in cats with hyperthyroidism than in healthy control cats.
Animals: Twenty-three hyperthyroid cats, 19 cats with HCM without congestive heart failure, and 19 euthyroid, normotensive healthy cats eight years of age or older. Fourteen of the hyperthyroid cats were re-evaluated three months after administration of 131I.
Methods: A complete history, physical examination, complete blood count, serum biochemistries, urinalysis, blood pressure measurement, serum T4 concentration, plasma concentrations of NT-proBNP and cTNI, and echocardiogram was prospectively obtained from each cat.
Results: Hyperthyroid and HCM cats had plasma NT-proBNP and cTNI concentrations that were significantly greater than healthy older cats, but there was no significant difference between hyperthyroid and HCM cats with respect to concentration of either biomarker. In hyperthyroid cats that were re-evaluated three months after 131I treatment, plasma NT-proBNP and cTNI concentrations as well as ventricular wall thickness decreased.
Conclusions and Clinical Relevance: Although there may be a role for NT-proBNP in monitoring the cardiac response to treatment of hyperthyroidism, neither NT-proBNP nor cTNI can be used to distinguish hyperthyroid cats from cats with HCM. Therefore, the thyroid status of older cats should be ascertained prior to interpreting results of cardiac biomarker testing.

PhD thesis, Murdoch University, 2007. http://researchrepository.murdoch.edu.au/158/.
Full textAbstract:
Cat ownership in Australia is declining compared to an increasing trend of cat ownership in the United Kingdom, United States and Europe. The decline in Australia may be linked to concerns over perceived impacts of cat predation and an associated dislike of cats. However, while there are numerous studies on feral cats and their impacts on declining native fauna, the impact of pet cats on suburban wildlife or fauna in remnant bushland is relatively unknown although there is a wide perception of risk. The primary aim of this thesis was to apply the precautionary principle to the question of the putative impact of pet cats on the abundance and diversity of small mammals in urban bushland adjacent to low-density suburbia in the City of Armadale, a municipality on the south-east fringe of Perth, Western Australia. At the time of writing, Western Australia is yet to introduce state legislation governing cat control although many local councils within the state have either implemented or are in the process of implementing cat regulations.
The precautionary principle was deemed an ideal approach to this question, because it provides a rationale for deciding on possible actions where both the potential risk to environmental values and the uncertainty about possible impacts are high. In such cases the precautionary principle requires two broad lines of action: firstly, detailed consultation with stakeholders to determine their perceptions of risk and the actions they are prepared to take to reduce it and, secondly, research to reduce uncertainty.
With regard to stakeholder consultation, local residents were surveyed in regard to their attitudes and current cat husbandry practices. A substantial proportion of respondents within this municipality believed cat regulations were necessary (75% of owners and 95% of non-owners). At least 70% of both owners and non-owners agreed with the propositions that cats not owned by licensed breeders should be desexed, local councils should restrict the maximum number of cats that can be owned on one property and that pet cats entering nature reserves are harmful to wildlife. Most (c.85%) cat owners agreed that they would license their cats if that became compulsory. Although fewer owners (c.60%) were prepared to keep their cats on their property at all times to protect wildlife, over 80% were willing to confine their cats at night if it was required. Owners seemed to be substantially motivated by the value of these measures in reducing injury to cats and facilitating the return of lost animals rather than concern over wildlife protection.
Attempts to reduce uncertainty involved (i) assessing roaming patterns of pet cats to determine the sizes of appropriate buffer zones around nature reserves, and (ii) determining species diversity, species richness and abundance of small mammals in remnant bushland adjacent to sub-divisions with varying regulations governing cat husbandry. Radio tracking results to assess cat roaming patterns showed substantial variation in home range size between cats in high density suburbia (ranged between 0.01 ha - 0.64 ha) and those in low density suburbia (ranged from 0.07 ha - 2.86ha). Larger home range sizes of cats in the rural areas (up to 2.9 ha) suggest buffer zones of up to 500 metres around nature reserves are needed to exclude almost all roaming cats. The abundance and species richness of small mammals were investigated in four areas of remnant bushland. Two were adjacent to subdivisions where cat ownership was unrestricted, one next to a subdivision where cat ownership was prohibited and the remaining one next to a subdivision where compulsory night curfew and bells on pet cats were enforced. No definitive evidence of predatory impact by pet cats on the small mammals was found. Mammal species diversity was not significantly different between sites and species richness and absolute abundance were not higher in sites where cats were restricted. Vegetation comparisons showed significant differences in the structure and species composition of the vegetation between most sites and the mammal species richness and abundance appeared linked to ground cover density in the various sites. This factor, not cat restrictions, appeared to be the primary determinant of species richness, species diversity and absolute numbers of small mammals in these sites.
This study in the City of Armadale has shown that the implementation of proposed cat legislation must have a 'whole of ecosystem' approach, i.e. protecting identified remnant bushland containing biodiversity from threatening processes such as plant disease and inappropriate fire, especially arson, as well as possible predations from pet cats. Habitat restoration and protection may be more important conservation activities than regulation of cats. Regulation of cats can be done at differing levels of intensity and cost, bearing in mind that this community is receptive to regulation of some aspects of cat ownership. Community education on the values of cat confinement in regards to cat welfare might increase chances of compliance.

Full textAbstract:
Postural control incorporates multiple neural and mechanical systems at various levels of the motor control system, yet the question of how all these systems interact remains unanswered. This dissertation describes development of a biologically based, three-dimensional mathematical model of the forelimb of the domestic cat that integrates skeletal anatomy, muscular architecture, and neural control. Previous work has shown that muscle architecture profoundly affects its function. However, even though the forelimbs of quadrupeds contribute to posture and locomotion differently from hindlimbs, most models of quadruped motion are based upon hindlimb mechanics. The proposed work consists of three main steps: (1) architectural and anatomical characterization, which involves acquisition of muscle attachment data, measurement of whole muscle and muscle fiber properties, and estimation of limb kinematic parameters; (2) model development and implementation, wherein the data will be integrated into a mathematical model using special-purpose software; and (3) model validation, including verification of model estimates against experimentally obtained measurements of muscle moment arms, and prediction of limb kinetics, namely end-point forces arising from perturbations to the limb. It was found that the forelimb does indeed possess structure, particularly at the shoulder and antebrachium, that allows for more diverse movements. The neural wiring in these regions is more complex than in the hindlimb, and there exists substantial muscular structure in place for non-sagittal motion and object suppression and retrieval. Other results showed that the kinematics of the limb alone produce a restorative response to postural disturbance but that the magnitude is reduced, indicating that neural input acts as a modulatory influence on top of the intrinsic mechanism of limb architecture. Furthermore the model demonstrated many of the essential features found in the experiments. This study represents the implementation of the first forelimb model of the cat incorporating mechanical properties and serves as a key component of a full quadruped model to explore posture and locomotion.

Full textAbstract:
Background: Hyperthyroid cats are predisposed to thrombus formation. The mechanism for thrombogenesis is currently unknown, but could be associated with altered hemostasis as seen in hyperthyroid humans.
Objective: The purpose of this study was to evaluate markers of hemostasis in hyperthyroid cats compared to healthy cats, and in hyperthyroid cats before and after treatments with radioactive iodine (RIT).
Methods: Twenty-five cats with hyperthyroidism and 13 healthy euthyroid cats > 8 years of age were studied. Prothrombin time (PT), activated partial thromboplastin time (aPTT), fibrinogen, antithrombin (AT), D-dimers, thrombin-antithrombin complexes (TAT), von Willebrand Factor antigen (vWF:Ag), and activity of factors VIII and IX were measured. An echocardiogram was performed in all cats and healthy cats with abnormal echocardiograms were excluded. Measurements of hemostasis were evaluated again in 7 cats > 6 months after RIT and deemed to have restored euthyroid status.
Results: There is a significant likelihood of being in hypercoagulable state based on hyperthyroid state (P = 0.019) and serum T4 level is significantly associated with predicating hypercoagulability (P = 0.043). Hyperthyroidism is associated with significantly higher median fibrinogen concentration (P < 0.0001), higher median AT activity (P < 0.0001), and higher median vWF:Ag level (P = 0.01) with all values decreasing significantly post-RIT. Fibrinogen and AT had a strong positive correlation with serum T4 value (r = 0.79; 95% CI 0.63 - 0.89 and r = 0.70; 95% CI 0.50 - 0.84, respectively). Presence of an abnormal echocardiogram in hyperthyroid cats was associated with a significantly higher median fibrinogen concentration (P = 0.03). Echocardiographic status did not have a significant impact on the remaining hemostatic markers in hyperthyroid cats.
Conclusions: These results provide evidence of altered hemostasis and hypercoagulability in hyperthyroid cats that do not appear to be solely attributed to cardiac abnormalities. These differences of altered hemostasis resolved after radioiodine therapy, but further studies are warranted to determine if hypercoagulable state resolves.Master of Science
In feline hyperthyroidism, there is a predisposition for thrombus formation. An alteration of hemostasis has been documented in hyperthyroid humans, but despite reports of thrombus formation in hyperthyroid cats, the underlying mechanism is currently unknown. Hyperthyroidism can lead to cardiac abnormalities that could possibly contribute thrombus formation, although thrombus formation has occurred in hyperthyroid cats without detected abnormalities. The goal of this study was to evaluate markers of hemostasis in hyperthyroid cats presenting for radioiodine therapy to evaluate for presence of hypercoagulability. Twenty-five hyperthyroid cats were evaluated with hemostasis panels and echocardiograms. The results were compared to a group of 13 healthy cats. Markers of hemostasis and echocardiograms in 7 hyperthyroid cats were also compared to results 6 months or greater post-radioiodine therapy. There was evidence of altered hemostasis and hypercoagulability in hyperthyroid cats. The alterations noted resolved after radioiodine therapy and do not appear to be solely attributed to cardiac abnormalities seen in hyperthyroid cats.

Full textAbstract:
Normal levels of CO₂ are responsible for the maintenance of approximately 30% of sympathetic neurogenic vascular tone in intact cats. The central medullary chemoreceptors have been implicated as the major source of this CO₂ dependent neurogenic vascular tone. However, it is possible that spinal cord CO₂ sensitivity could also have mediated a portion of neurogenic vascular tone.
Cats with acute and chronic spinal transections can maintain near normal levels of systemic arterial blood pressure, and show cardiovascular and sympathetic reflex changes in response to a variety of stimuli.
Thus, it seemed likely that the acute spinal cat could exhibit the spinal component of CO₂ mediated sympathetic neurogenic vascular tone. Therefore the effects of systemic CO₂ increases on the perfusion pressures of vascularly isolated hindlimbs autoperfused at constant flow (as an indication of vascular resistance and sympathetic vascular tone) were studied in the acute cervical spinal cat. The contributions of the lumbar sympathetic system and the adrenal glands to perfusion pressure responses to CO₂ were evaluated.
Experiments were carried out in mongrel cats with acute cervical (C2) transections. Each cat had one leg denervated by cutting and stripping the lumbar sympathetic chain from L₁-L₇. In all cats each hindlimb was vascularly isolated and perfused with blood taken from the abdominal aorta. Bilateral adrenalectomy was performed on 8 animals.
CO₂ administration for 5 minutes resulted in biphasic increases in the perfusion pressures of both legs which were designated peak1 (P1) and peak2 (P2). Increasing PCO₂ from 16 to 38mm Hg, and from 16 to 62mm Hg resulted in significant P1 and P2 responses of the innervated leg. This also resulted in a significant P2 response, and an observable but insignificant P1 response, of the denervated leg. Adrenalectomy reduced P1 and P2 responses of the innervated leg, and abolished the P1 response and reduced the P2 response of the denervated leg. In non-adrenalectomized cats increasing PCO₂ also resulted in a significant increase in systemic arterial pressure (SAP) with no changes in heart rate (HR). In adrenalectomized cats increasing PCO₂ resulted in an observable but non-significant increase in SAP and a significant decrease in HR.
These results suggested that:
1) The P1 response was primarily a sympathetic neurogenic response to increased CO₂.
2) The P2 response was primarily a hormonal response to CO₂ in the denervated leg, and a combination of hormonal and sympathetic neurogenic responses to CO₂ in the innervated leg.
3) The adrenal glands were mostly involved in the P2 response to CO₂, but possibly had a small role in the P1 response.
4) Other non-adrenal vasoconstrictor hormones may have played a role in the P2 response to C0₂.
5) Likely, CO₂ initially activated the sympathetic system to directly increase neurogenic tone, perhaps by stimulating sympathetic afferent or efferent neurons, or hypothetical spinal chemosensitive regions. Progressively the adrenal and possibly other unidentified vasoconstrictor hormone systems became activated, either directly by CO₂ or indirectly by CO₂ mediated sympathetic activation. These hormone systems may have also played a role in CO₂ mediated maintenance of vascular tone.Medicine, Faculty of

Full textAbstract:
Under det närmaste seklet kommer Sverige att vara med om en klimatförändring med en ökad nederbörd upp mot 40 % i delar av landet. Översvämningar kommer bli vanligare och kraftigare skyfall under kortare perioder är det största hotet mot ett fungerande avrinningssystem. De mängder dagvatten som ska hanteras i stadsbebyggelse kan vara mycket stora på grund av att grönytor har bytts ut mot hårdgjorda ytor. SWMM-CAT (Storm Water Management Model – Climate Adjustment Tool) är ett program som kan skapa prognoser för framtida klimatförändringar. Genom att söka på koordinater eller postnummer i USA kan användaren få fram data för förändring i nederbörd, avdunstning, temperatur och största dygnsnederbörd vid olika återkomsttider vid just den platsen sökningen skett i. Informationen kan användas för att få en uppfattning i hur dessa parametrar kommer att ändras i framtiden. Informationen kan även sparas till SWMM (Storm Water Management Model) i form av klimatjusteringsfaktorer. SWMM är ett simuleringsprogram som används för planering och analys av dagvattenavrinning. Med hjälp av dessa klimatjusteringsfaktorer kan man vid projektering av avloppssystem vara mer förberedd och dimensionera med hänsyn till det framtida klimatet. Genom uppbyggnad av en modell i SWMM har vi jämfört resultatet av en simulering utan klimatjusteringar och en simulering med klimatjusteringar. Resultatet visar att vattenflödet från avrinningsområdet skulle öka från 43 l/s till 66 l/s. Utifrån denna flödesökning ser vi att det finns en stor vikt att beakta hur klimatförändringarna kan komma att påverka dessa flöden vid dimensionering av avloppssystem. SWMM-CAT är ett lätthanterligt och användarvänligt program som enkelt kan användas för att få en inblick i hur klimatförändringarna kan komma att påverka temperatur och nederbörd. Det krävs dock erfarenhet av SWMM för att göra korrekta simulationer med justeringsfaktorer från SWMM-CAT. Eftersom klimatförhållanden skiljer sig geografiskt går SWMM-CAT inte att tillämpa i Sverige då prognoserna är framtagna över ett rutnätssystem i USA. Med hjälp av forskning från Rossby Centre är det möjligt att ta fram data för framtida förändringar i nederbörd, avdunstning och temperatur för Sverige. Det tror vi är tillräckligt med underlag för att skapa ett program liknande SWMM-CAT i Sverige. För att på bästa sätt möta klimatförändringarna i svenska stadsmiljöer påstår vi att man bör kombinera klimatprognoser med mer öppen dagvattenhantering.Sweden will during this century experience an increased amount of precipitation, up to 40 % in some parts of the country. Flooding will be more common and heavy rain during short periods of time is the greatest threat of having a functioning drainage system. The amount of storm water that urban areas will have to handle can be massive due to the lack of infiltration areas. SWMM-CAT (Storm Water Management Model – Climate Adjustment Tool) is software that can create future climate change projections. By searching for coordinates or zip-codes in the US the user can receive data for changes in precipitation, evaporation, temperature and 24-hour design storm at a specific location. The information can be used to get more knowledge of how these parameters will change in the future, but also to import as adjustment factors to SWMM (Storm Water Management Model). SWMM is a simulation software for planning and analysis of storm water runoff. The adjustment factors allow planning of sewer systems with consideration of future climate change. To compare the results of a simulation with SWMM-CAT and without SWMM-CAT we constructed a SWMM-model. The result showed an increased water flow from the sub catchment area from 43 l/s to 66 l/s. This result displays that it is important to consider how the climate change can affect the sizing of sewer systems. SWMM-CAT is a user friendly software and can easily be used to predict future climate change outcomes related to precipitation and temperature, but it demands experience from SWMM to make correct simulations with adjustments from SWMM-CAT. Since climate changes varies geographically, SWMM-CAT cannot be used in Sweden because the projections is based on a grid system over the US. The research of Rossby Centre provides future climate change projections in precipitation, evaporation and temperature for Sweden. We believe that it is sufficient data to create a software similar to SWMM-CAT in Sweden. We believe that the best way to cope with the climate changes in urban areas is to combine future climate projections with low-impact development.

Full textAbstract:
The physiological characteristics and organization of cat primary somatosensory cortex (SI) were studied in electrophysiological and anatomical experiments. In single cell recording experiments, quantitatively controlled mechanical stimuli were used to examine the responses of SI cortical neurons to the velocity component of skin or hair displacement. The firing frequency of most rapidly adapting neurons increased as stimulus velocity was increased. Rapidly adapting neurons were classified based on their response patterns to constant-velocity ramp stimuli. Neurons in these classes differed significantly in sensitivity to stimulus velocity and amplitude, adaptation rate, and spontaneous firing rate. The results suggest that frequency coding of stimulus displacement velocity could be performed by individual SI rapidly adapting neurons, and that the classes of rapidly adapting neurons may play different roles in sensation of tactile stimuli. Tract-tracing experiments were used to investigate the ipsilateral corticocortical connections of areas 3b and 2 in SI. Different patterns of connections were found for these areas: area 2 projects to areas 3b, 1, 3a, 5a, 4 and second somatosensory cortex (SII), and area 3b projects to areas 2, 1, 3a and SII. To further compare the organization of these areas, the thalamic input to the forepaw representation within each area was studied. The forepaw region in area 3b receives thalamic input exclusively from ventroposteriopr lateral nucleus (VPL), while area 2 receives input from VPL, medial division of the posterior complex (PoM), and lateral posterior nucleus (LP). These results suggest that area 2 lies at a higher position in the hierarchy of somatosensory information flow.

Full textAbstract:
Proteus mirabilis PM13 is a well characterized chloramphenicol-sensitive isolate which spontaneously gives rise to resistant colonies on solid media containing chloramphenicol (50ug/ml) at a plating efficiency of between 10-4 and 10-5 per cell per generation. When a chloramphenicol resistant colony is grown in liquid medium in the absence of the antibiotic for I50 generations a population of predominantly sensitive cells arises. The cat gene responsible for the phenomenon is chromosomal, and has been cloned from P.mirabilis PMI3 with DNA prepared from cells grown in the absence or the presence of chloramphenicol. Recombinant plasmids which confer resistance to chloramphenicol carry an 8.5-kb PstI fragment irrespective of the source of host DNA. The location of The cat gene within the PstI fragment was determined by Southern blotting with a cat consensus 'active - site' oligonucleotide (5'-CCATCACAGACGGCATGATG-3') corresponding to the expected amino acid sequence of the active site region of chloramphenicol acetyltransferase. DNA sequence analysis has revealed a high degree of homology between the P. mirabllls cat -gene and the type I ca-t variant (Tn9), 76% at the amino acid level and 73% when nucleotides in the coding sequence are compared. The mechanism for the appearance and disappearance of chloramphenicol resistance in P. mirabilis appears to be associated with a host-specific trans-acting element which controls cat gene expression. A precedent for such a control network is given by phase variation in Salmonella typhimurium, where an invertible DNA segment controls the transcription of a trans-acting regulatory element. A comparison of the 5' regions of the S.typhimurium flagellin genes in and H2, which are alternately expressed by a flip-flop control mechanism with the 5' region of P.mirabilis cat show blocks of homology. Whether or not this homology is significant in the regulation of cat gene expression has not been determined.

Two novel techniques for future CAT system are presented. Transmission descattering is a singleshot method to differentiate unscattered and scattered components of light transmission through a scattering material. Directly-transmitted components travel in a straight line from the light source, while scattered components originate from multiple scattering centers in the volume. Angularly varying scattered light is strategically captured via a lenslet array placed close to the image plane and the unscattered direct component is computed based on separable scattered components. The disadvantage is a reduction in spatial resolution. As an application, the enhanced tomographic reconstruction is demonstrated using estimated direct transmission images. The other technique is single-shot 3D reconstruction of a translucent object. Multiple light sources form images of a translucent object at different projection angles onto a screen. Those images are captured by a single-photo in a coded format via lenslet array. The projection image casted from each light source is separated from each other by a decoding process and in turn the images are combined to reconstruct 3D shape of the translucent object by ART method.

devido a adopção (nove). A latência de chegada à posição próxima da não-recompensada
foi semelhante nos três grupos. Na latência de chegada à posição próxima da
recompensada foram encontradas mais diferenças, com os gatos treinados a mostrarem
latências menores o que poderá ser indicativo de maior otimismo.

Full textAbstract:
Subclinical cardiomyopathy (CM) sometimes is identified after abnormalities are detected during auscultation of apparently healthy cats. Little is known regarding the prevalence of CM in this population. Furthermore, the clinical importance of auscultatory abnormalities in apparently healthy cats is unclear. In order to estimate the prevalence of murmurs and CM, we prospectively evaluated a sample of apparently healthy cats. Cats with systemic hypertension or hyperthyroidism were excluded. 103 cats were subject to physical and echocardiographic examinations which were performed by two different investigators; the echocardiographer was unaware of the physical findings. Left ventricular wall thickness was determined by two-dimensional echocardiography in short- and long-axis planes. Left ventricular hypertrophy (LVH) was defined as an end-diastolic wall thickness greater than or equal to 6 mm. Cats with LVH but without left ventricular dilation were considered to have hypertrophic CM (HCM). Cardiomyopathy was identified in 16 cats (15.5%; 95% CI: [9.2, 24.0]); 15 had HCM and one had arrythmogenic right ventricular cardiomyopathy. Murmurs were detected in 16 cats (15.5%; 95% CI: [9.2; 24.0]); of these cats, 5 had CM. Of 15 cats with HCM, 11 had segmental LVH, three cats had diffuse LVH, and one cat had borderline LVH and marked systolic anterior motion of the mitral valve. The sensitivity and specificity of murmurs for detection of a CM was 31% and 87%, respectively. The prevalence of feline subclinical CM in Southwest Virginia is near 16%; approximately a third of these cats had murmurs. In apparently healthy cats, a cardiac murmur is an insensitive marker of the presence of CM.Master of Science
