Métodos diagnósticos para detecção da Leucemia viral felina

The feline leukemia virus (FeLV) was described in 1964 by William Jarrett and collaborators wen find viral particles attached to the membrane of lymphoblasts in cat with lymphoma. The virus belongs to the family Retroviridae, subfamily oncornavirus. With worldwide distribution, the occurrence of FeLV has 1.6% in healthy cats and 10.8% in sick cats in Brazil. The mortality of persistently viremic animals in catteries is about 50% in two years and 80% in three years. In catteries that have endemic feline Coronavirus (FCoV), FeLV and / or Feline Immunodeficiency Virus (FIV), the FeLV infection has greater contribution to mortality. The test for infection and FeLV positive cats segregation is the main way to prevent the spread of infection. The diagnostic methods are based on clinical signs and changes compatible with FeLV infection observed by physical examination, complete blood count, X-ray, bone marrow aspirate and biochemical. The viral p27 protein is produced in infected cells in high amounts and is found in abundance in the cytoplasm and in body fluids enabling diagnosed methods such as enzyme-linked immunosorbent assay - ELISA and direct immunofluorescence, detection of viral genome (Chain Reaction Polymerase - PCR) and detection of the virus by virus isolation. Although diagnostic tests are highly sensitive, it should be made more than a confirmatory test, especially serological due to variable characteristic of the progress of infection

Caracterização da demanda do pronto socorro do Hospital das Clínicas da Faculdade de Medicina de Botucatu - UNESP

The demand for health services can be understood as an application needs the user has. The inability to use the outpatient services and limited supply of these make it possible for users to browse sites that focus attention on a greater possibility of entry doors, in which first-aid centers and hospital emergency match this profile, distorting the flow of patients in the network through an inverse demand of the movement hierarchy. Added to this, the burden of care in these services results in overcrowding and poor quality of care. Evaluate the demand of the visits occurred in the Emergency Room of the Hospital of the Medical School of Botucatu / UNESP (PS - HC - FMB / UNESP) during June-July 2010. A transversal, descriptive and retrospective. For data collection sheet was used in the proposed Service unit and the data it was filled out the form with the necessary items for the search. Made an exploratory analysis and frequency distributions for categorical variables of the form. Females predominated (56%) and aged 61 years or older with 30%. 96.5% were owned by DRS VI, and 62.5% of Botucatu. The attendance by the physician on duty and corresponded to 57.7% among the 23 medical specialties, Gastric (7.0%), Cardiology (4.5%), Medical (4.4%), urology (4.2%) and Pulmonology (4.1%) were the ones that stood out. The medical procedures performed that stood out were X-ray (46.4%) and electrocardiogram (ECG) (42.3%) and in most specialty care occurred, only the daily consultation with the patient. It was possible to characterize, so the demand for PS - HC - FMB / UNESP for the period June- July 2010, The predominance of the elderly shows that come along with aging diseases and addictions, causing a greater need for health services. Moreover, this study showed that the high number of visits is related to both the daily demands that the tertiary hospital has the same transformation...

Neurobiologia da doença de Alzheimer

A Doença de Alzheimer (DA) tem sido conceituada como uma doença de caráter duplo, inicialmente por possuir um fenotípico clínico centrado na presença de uma demência progressiva que inclui comprometimento da memória como uma característica definitiva, além do envolvimento de outros domínios cognitivos ou habilidades. É caracterizada também por alterações neuropatológicas específicas que incluem lesões intraneuronais (emaranhados neurofibrilares) e extracelulares (placas senis), que podem ser acompanhados por perda sináptica e depósitos vasculares amiloides (Dubois et al, 2010). A constatação do processo neurodegenerativo se evidencia por meio da atrofia cerebral, especialmente, em hipocampo e córtex entorrinal constatada por neuroimagem (por exemplo, a ressonância magnética e tomografia computadorizada). Dentro desse conceito, esse estudo teve como objetivo fazer uma investigação geral com base na literatura especializada, com análise de artigos relevantes, referentes aos aspectos neurobiológicos associados à Doença de Alzheimer. Foram abordados tópicos como: atrofia cerebral, processo neurodegenerativo, biomarcadores, neuroimagem (com foco na escala de Urs et al.,2009) e aspectos clínicos

Caracterização e origem da composição química da incrustação e simulação de cenários de perda de energia em setor da rede de abastecimento de água da cidade de Rio Claro - SP

The purpose of this work was the inlay’s characterization from the water supply networks of Rio Claro-SP city; as well analyze the influence of network’s aging in the actual system. To do this, some samples of inlays were collected and made chemistry analysis and X-Ray Diffraction Spectrometry. The history of the source water quality was also analyzed, to make possible to known the origins of the inlays. To evaluate the performance of the network, some different scenarios have been simulated, varying the resistance coefficient of the water supply networks of Rio Claro-SP. The characterization results showed that there are basically oxide and hydroxide of iron (magnetite and goethite) and quartz in the inlays, which are materials of high hardness. The hydraulic simulations indicated that the simulated scenarios had a variation of ~2000% in terms of loss of energy

Espondilomielopatia cervical caudal em cães: diagnóstico por imagem

The Caudal Cervical Spondylomyelopathy, also known as “Wobbler syndrome” is a neurological disorder that affects mainly breeds of large and giant size, especially Doberman pinsher and Great danes. Its aetiology is multifactorial and leads to a narrowing of the spinal canal by morphological and positional caudal cervical vertebrae (C5, C6 and C7), causing compression of the spinal cord and nerve roots. The clinical signs presented by the affected animals are progressive ataxia of hindlimbs and, later, the forelimbs, sometimes progressing to tetraparesis. Neck pain may be present. The diagnosis is made through the association of clinical signs and diagnostic imaging such as radiography, myelography, computed tomography and magnetic resonance imaging. According to the classification of the lesion obtained by imaging examinations, the conservative or surgical treatment is established and the prognosis is variable in accordance with the degree of affection of the spinal cord

Síntese e caracterização de ferritas de manganês e zinco visando aplicação como agente de contraste em diagnóstico médico

This work aims to synthesize the manganese and zinc ferrite, by the polymeric precursor method, in order to obtain materials with appropriate characteristics for the application in medical diagnosis techniques. The manganese and zinc ferrite powders with the composition of Mn(1-x)ZnxFe2O4, where x=0,23, were prepared and calcined in air at different times and temperatures. The X-ray diffraction (XRD) data show that the sample calcined at 400°C crystallize as ferrite (monophase), but in an inverted spinel structure (high content of iron occupying manganese tetrahedral site and manganese occupying the iron octahedral site). The samples calcined at temperatures between 600°C and 900°C shows the secondary phase of hematite and the sample calcined at 1100oC shows to be monophase in ferrite with normal spinel structure. The monophase powders of ferrite showed a reduction in the surface area and an increasing in the pore size for higher calcination temperatures. The magnetic analysis show that the sample calcined at 400°C presents satisfactory magnetization at room temperature, however, it behaves as diamagnetic material at low temperatures (10K). The powder containing hematite, without the partial substitution of iron ions by manganese, showed to have low transition temperature, and consequently low magnetization at room temperature. The hematite, when partially substituted, provides materials with irregular magnetization at the saturation region. The powder calcined at 1100°C shows high magnetization either at room temperature or low temperature (10K)

Análise da densidade óssea de rádio-ulna de cães SRD utilizando o método de imersão

Imaging diagnosis is a medical specialty that uses imaging techniques to perform diagnosis. In diagnostic imaging various methods are used such as direct absorption of photons - SPA and DPA, radiographic photometry, the dual-energy radiographic absorptiometry - DEXA, ultrasound, magnetic resonance imaging, computed tomography and optical densitometry in radiographic image. The dog can be considered one of the most widely used animals in the study of bone diseases and searching for a reliable diagnosis, although not an ideal model for the study of osteoporosis, because these animals tend not to develop a decrease in bone mineral density. The objective of this study was to analyze bone density in mongrel dogs from the determination of the variation of density along the radio-ulna bone and also the mean value related to gender, weight and age of individuals. The density analysis carried out showed that for this data set, there is a significant difference in the case of gender and age of the animal and may generalize according to these variables. The only significant difference was found in the weight, which increases bone mass is related to weight gain through the growth of the animal
