Impacto do controle glicêmico sobre as complicações associadas ao diabetes mellitus na osseointegração

The increased prevalence of diabetic individuals has become a public health problem. Diabetes Mellitus is a metabolic disorder characterized by an increase in plasma glucose levels. It impairs the physiological equilibrium in utilization of carbohydrate by tissues. The persistent hyperglycemia can produce deleterious effects on bone formation due the microvascular complication. The present paper reviews the bibliography linking the impact of glycemic control at complications associated at diabetes mellitus on osseointegration. In experimental models of diabetes it was observed a reduced level of bone-implant contact. This failure can be reduced by means of hyperglycemia control. Also, several studies point the beneficial effect of coated implant on osseointegration process. It is necessary to take special care into account for the placement of implants in diabetic patient and improve the percentages of implant survival. A rigorous control of plasma glycaemia, together with other measures, like as absence of chronic complications, good oral hygiene and regular medical follow-up has been related to rising the percentages of successful in diabetic patients.

Lissencefalia em cães e gatos: revisão

Lissencephaly is a condition characterized by a lack of cerebral convolutions and sulci, which results from defective migration of nervous cells precursors in the telencephalus. The cause is presumably genetic. Lhasa-Apso dogs are most frequently affected, even though it may also occur in association with cerebellar hypoplasia in the Irish Setter, Wire-Haired Terrier and Samoieda breeds. This association was also reported in a cat. Clinical signs consist of dementia, aggressiveness, seizures, visual and olfactive dysfunctions, slow postural reactions and reduced menace response. Definitive diagnosis requires exams such as magnetic resonance imaging, cerebral biopsy or necropsy. There is no specific therapy for this disease, and seizures must be treated with anticonvulsants. The aim of this study is to review the literature regarding lissencephaly.

Tratamento de um papagaio-verdadeiro (Amazona aestiva) com síndrome do arrancamento de penas usando a técnica de vínculo social e a correção nutricional: relato de caso

The blue-fronted parrot (Amazona aestiva) belongs to the order Psittaciformes and family Pscittacidae. It is widely held as a pet because of its peculiar characteristics. The owners of such animals, however, frequently report behavioral problems. The absence of proper environmental stimuli generated by confinement and lack of social engagement can predispose these animals to characteristic behaviors related to stress, which can be manifested as a feather plucking syndrome. The present study reports the case of a blue-fronted Amazon parrot with a two-year history of feather plucking. The psychosomatic disease was halted once the animal created an emotional bond with a human being. This finding reinforces the social nature of this species and raises questions about the welfare of captive birds of this order.

Evaluación de la actividad del sistema de transporte de electrones en zooplancton con presencia o ausencia de sustratos específicos

Se comparan dos métodos de detección del sistema de transporte de electrones (Båmastedt, 2000 y Owens & King, 1975), hallando que la no adición de sustratos específicos, propios del sistema, no es lo suficientemente sensible para la detección de la capacidad respiratoria y que no presenta ninguna relación con la biomasa. Se demuestra que el receptor artificial de electrones INT, es reducido en reacciones no enzimáticas por algunas sustancias (ácido ascórbico, glutatión, cisteína y potencialmente la vitamina B12), presentes en concentraciones intracelulares.
