A História da Computação através de um Museu Virtual Interativo utilizando Mundos Virtuais 3D

Mundos Virtuais 3D tem sido cada vez mais utilizados no contextoeducacional, buscando aumentar a interacao e engajamento dos estudantes junto asatividades academicas. Neste contexto, este artigo tem como objetivo apresentar ummuseu virtual 3D que apresenta a historia da computacao, desenvolvido atraves doambiente virtual OpenSimulator. Ao propor a utilizacao de mundos virtuais 3D noprocesso de ensino e aprendizagem, pretende-se alcancar uma maior interacao entre osestudantes e, em especial dos estudantes com o objeto de estudo, neste caso os artefatosda historia da computacao, buscando contribuir para a construcao de novasabordagens educacionais e, principalmente, na motivacao dos estudantes pela areatecnologica.

Study of the Anti-Photoaging Effect of Noni (Morinda citrifolia)

During the aging process, morphological changes in the human skin appear most noticeably in areas of frequent exposure to ultraviolet (UV) light from the sun, such as the face and hands. Chronic UV exposure induces photoaging, characterized by pigmented spots and wrinkles in the skin. Gradual destruction of the ozonosphere has raised photoaging risk. This has led to rapid growth of the anti-photoaging cosmetic market, especially among women with young and fair skin. Sunscreen agents are a first choice for protection against photoaging. However, a certain amount of UV irradiation penetrates skin dermis, and adverse effect may occur with use of these agents. Because of this, a current trend is the development of safer cosmetic ingre‐ dients that effectively inhibit the UV signaling pathways leading to photoaging [1].

Factors associated with the quality of life of adults subjected to hemodialysis in a city in northeast Brazil

There is a known association between low scores for quality of life (QOL) and higher rates of hospitalization, mortality in hemodialysis vascular access catheter, older age, lack of regular occupation, presence of comorbidities and hypoalbuminemia. There is still no agreement about the influence of sex, educational level, socioeconomic status and treatment time on the worst levels of QOL.

Eculizumab for the treatment of atypical hemolytic uremic syndrome - Case report and revision of the literature

SHU atypical (aHUS), that is, not associated with Escherichia coli Shiga toxinproducing, is seen in 5 to 10% of cases of Hemolytic Uremic Syndrome (HUS), and can occur at any age and may be sporadic or familial. The prognosis in these cases is reserved, with high mortality and morbidity in the acute phase of the disease, and about 50% of cases can develop chronic kidney disease. The increased knowledge of the pathogenesis of aHUS (overactivation of the alternative pathway of complement), was accompanied by the appearance of a drug, eculizumab, which acts as an inhibitor of membrane attack complex. Our goal is to report a case of infant with aHUS with excellent clinical and laboratory response with the use of eculizumab. 14 month old infant, previously healthy, male, presented anemia and thrombocytopenia at 12 months of age. He was treated with corticosteroids and forwarded to our service for high blood pressure. However, the scans showed nephrotic proteinuria with renal involvement and hypoalbuminemia with direct Coombs negative. He developed anemia, thrombocytopenia, worsening of renal function and hypertension. Renal biopsy showed thrombotic microangiopathy (TMA). On the non-hemolytic anemia, thrombocytopenia and acute renal failure with histological substrate MAT, was diagnosed of aHUS. The patient received eculizumab excellent clinical and laboratory response. This case shows the importance of early diagnosis and treatment of the aHUS. Eculizumab is effective and keeps long-term remission, avoiding invasive measures such as plasmapheresis, which resolves only part of the picture.
