My Croatian Experience with General/ Family Practice

Despite the differences in organizational level and training of the new generation of family physicians general practice between the United Kingdom and Croatia shows many similarities. This article highlights some of these similarities and differences. It is written after a visit to the Family Medicine Department at School of Public Health »Andrija [tampar « and observations in various clinics in multiple locations including rural area in Croatia. Each primary care team in Croatia consists of only a doctor and a practice and a public health nurses with no availability of administration staff. As in the United Kingdom they have very heavy workload both clinical and nonclinical. In Croatia the lack of availability of commonly used community services in the United Kingdom brings extra challenges for Croatian colleagues. In Croatia presentation of patients with chronic disease and multiple co-morbidities and overall their management is not significantly different from the general practice of the United Kingdom

The impact of brain lateralization and Anxiety-Like behaviour in an extensive operant conditioning task in Zebrafish (Danio rerio)

© 2019 by the authors. Several studies in mammals, birds, and fish have documented better cognitive abilities associated with an asymmetrical distribution of cognitive functions in the two halves of the brain, also known as 'functional brain lateralization'. However, the role of brain lateralization in learning abilities is still unclear. In addition, although recent studies suggest a link between some personality traits and accuracy in cognitive tasks, the relation between anxiety and learning skills in Skinner boxes needs to be clarified. In the present study, we tested the impact of brain lateralization and anxiety-like behaviour in the performance of an extensive operant conditioning task. Zebrafish tested in a Skinner box underwent 500 trials in a colour discrimination task (red vs. yellow and green vs. blue). To assess the degree of lateralization, fish were observed in a detour test in the presence of a dummy predator, and anxiety-like behaviour was studied by observing scototaxis response in an experimental tank divided into light and dark compartments. Although the low performance in the colour discrimination task did not permit the drawing of firm conclusions, no correlation was found between the accuracy in the colour discrimination task and the behaviour in the detour and scototaxis tests. This suggests that neither different degrees of asymmetries in brain lateralization nor anxiety may significantly impact the learning skills of zebrafish

Ação do queijo e do iogurte na cárie dentária

Orientador : Fabian Calixto FraizMonografia (especialização) - Universidade Federal do Paraná, Setor de Ciências da Saúde, Curso de Especialização em Odontopediatria.Inclui referênciasResumo: A dieta tem papel fundamental na doença cárie dental. Os alimentos têm potencial para desenvolver ou paralisar as lesões de cárie. Já é conhecido que a sacarose e outros carboidratos fermentáveis participam do inicio e desenvolvimento de lesões de cárie. No entanto, o leite e seus derivados, queijo e iogurte, são exemplos de alimentos que tem a capacidade de interferir positivamente em um dos fatores determinantes no processo saúde-doença da cárie dentária, diminuindo a desmineralização dentária. O objetivo deste trabalho é analisar com base em revisão de literatura, o potencial anticariogênico destes derivados do leite. A partir desta revisão, concluiu que queijo e iogurte têm efeito anticariogênico pelo aumento da concentração de cálcio no biofilme dental, aumento no pH, estímulo da salivação, e em menor escala, pelas proteínas presentes no soro do leite e pela gordura. É importante que o odontopediatra conheça as características protetoras desses alimentos e inclua esse conhecimento na orientações dietéticas para a prevenção da cárie dentária
