Abstract: Development is the continuous change in global behavior over the life cycle of human beings, due to the interaction between the needs of the task, the individual's genetic and environmental conditions in which the child is. In order to evaluate possible changes during the development of children, several tests may be performed, including the Denver II Test composed of four assessment items: personal-social, fine motor adaptation, language and overall motor skills, being the latter the instrument used in this study. The objective was to evaluate the overall motor skills of children from a day care center. Seventeen children between 10 and 30 months of chronological age, average of 22.7 months old, participated, being 9 (52.95%) males and 8 (47.05%) females, of 21 children who join the nursery at a day care center in Presidente Prudente, SP. All children presented tests as "approved", in other words, they performed the activities suitable for the chronological age. Classifying the global motor according to the Development Screening Test (Denver II): 14 children (82.36%) achieved the score "advanced" and 3 children (17.64%) were classified as "normal". Regarding gender, the performance was slightly better in girls, because all the female children are beyond the item corresponding to the chronological age. Thus, the overall motor development in children from day care center evaluated by the methods used in this study was “normal” and “advanced” according to the chronological age.

Abstract: In this study we show that, after 24 h of interaction, myoblasts (61%) were more infected with T. gondii than myotubes (38%) and inhibition of myogenesis was about 75%. The role of adhesion molecules such as cadherin in this event was investigated. First, we demonstrate that cadherin localization was restricted to the contact areas between myocytes/myocytes and myocytes/myotubes during the myogenesis process. Immunofluorescence and immunoblotting analysis of parasite-host cell interaction showed a 54% reduction in cadherin expression at 24 h of infection. Concomitantly, a reduction in M-cadherin mRNA levels was observed after 3 and 24 h of T. gondii-host cell interaction.These data suggest that T. gondii is able to down regulate M-cadherin expression, leading to molecular modifications in the host cell surface that interfere with membrane fusion and consequently affect the myogenesis process.Toxoplasma gondii is an obligatory intracellular parasite and an important human pathogen. Humans acquire toxoplasmosis due to oocyst seeding from cats, consumption of raw or undercooked meat or vertical transmission to the fetus during pregnancy. Studies of environmental factors in several communities indicated an important role for cultural and eating habits on this infection transmission [1]. During natural vertical infections, Toxoplasma initially crosses the intestinal epithelium of the mother, disseminates into the deep tissues and traverses the placenta, the blood-brain and the blood-retina barriers [2]. In both immunocompromised and immunocompetent individuals, Toxoplasma infection can cause a severe ocular pathology [3,4]. These parasites are able to invade and rapidly replicate in any nucleated host cell and may develop cysts, predominantly in neural and muscular tissues, initiating the chronic infection stage.Until now little attention has been given to skeletal muscle as a model in experimental toxoplasmosis studies [5-9], though skeletal muscle is one of the main si

Abstract: the aim of this study was to investigate the agreement between diagnoses of calcified atheroma seen on panoramic radiographs and color doppler images. our interest stems from the fact that panoramic images can show the presence of atheroma regardless of the level of obstruction detected by color doppler images. panoramic and color doppler images of 16 patients obtained from the archives of the health department of the city of valen?a, rj, brazil, were analyzed in this study. both sides of each patient were observed on the images, with a total of 32 analyzed cervical regions. the level of agreement between diagnoses was analyzed using the kappa statistics. there was a high level of agreement, with a kappa value of 0.78. in conclusion, panoramic radiographs can help detecting calcifications in the cervical region of patients susceptible to vascular diseases predisposing to myocardial infarction and cerebrovascular accidents. if properly trained and informed, dentists can refer their patients to a physician for a cardiovascular evaluation in order to receive proper and timely medical treatment.

Abstract:

The Myasthenia gravis (MG) is an autoimmune disease that affects neuromuscular transmission and leads to a large variation of sensibility on depolarizing and nondepolarizing neuromuscular blocking drugs. Sugammadex is a new drug with the capability to successfully revert the nondepolarizing neuromuscular blocking. This case report will show a patient with MG that was scheduled for thymectomy, with the objective to use sugammadex to reverse a rocuronium induced deep level of neuromuscular block and observing the safe use of sugammadex without complications.
