A hipertensão arterial sistêmica é uma doença crônica degenerativa de etiologia multifatorial e poligênica, caracterizada pela presença de níveis tensionais elevados, sendo considerada um dos mais importantes fatores de risco para o desenvolvimento das doenças cardiovasculares. Estudos demonstram que cerca de um bilhão de indivíduos apresentam HAS em todo mundo, sendo esta patologia responsável por 7,1 milhões de morte a cada ano. Diversos fatores estão associados ao aumento da incidência da hipertensão arterial, como obesidade, dislipidemias, dieta rica em sal, alterações nos níveis hormonais e sedentarismo. Após o período da menopausa, observa-se significativa elevação nos valores de pressão arterial dessa população, sendo estes similares ou até maiores aos dos homens para esse mesmo período. O sistema renina-angiotensina (SRAA) desempenha importante papel no controle dos sistemas cardiovascular e renal e a angiotensina II é um potente vasoconstritor desse sistema, formado a partir da ação da Enzima Conversora de Angiotensina (ECA). Por outro lado, a recente descoberta da Enzima Conversora de Angiotensina 2 (ECA2), um homólogo da ECA, mudou todo o conceito do SRAA. A ECA 2 é responsável pela formação do peptídeo angiotensina- (1-7) a partir da clivagem do último aminoácido (fenilalanina) da angiotensina II. Recentes evidências têm demonstrado efeitos benéficos da angiotensina-(1-7) para as doenças cardiovasculares através da vasodilatação, efeito anti-arritmogênico, melhora na função contrátil pós-isquemia e inibição da proliferação celular do músculo liso vascular, sendo esses efeitos antagônicos àqueles observados pela angiotensina II. Dessa forma, o objetivo desse estudo foi analisar a atividade da ECA2, concentrações plasmáticas...(Resumo completo, clicar acesso eletrônico abaixo)

O diabetes mellitus do tipo 1 (T1D) é uma doença autoimune cujo tratamento é parcialmente eficaz. A terapia existente visa apenas controlar a progressão da patologia através da injeção diária de insulina exógena, portanto, uma alternativa terapêutica ou profilática para a doença é necessária. A indução do T1D por administração de estreptozotocina (STZ) em camundongos C57BL/6 é considerada um modelo bastante adequado para a investigação dessas estratégias. Além disto, vários trabalhos demonstram que o contato com antígenos ambientais pode diminuir ou impedir as manifestações clínicas do T1D e de outras doenças autoimunes. Assim, o objetivo geral desta investigação foi avaliar o efeito da infecção prévia com Strongyloides venezuelensis no desenvolvimento do T1D. Inicialmente, acompanhamos a dinâmica da infecção em camundongos C57BL/6 para a determinação da resposta imune estabelecida na fase de recuperação da infecção, e posteriormente, avaliamos o efeito da infecção no T1D. Durante a fase de recuperação, caracterizada pelo desaparecimento de ovos nas fezes, ocorreu uma resposta imune de padrão misto (Th1/Th2) com predomínio de Th2, caracterizado pela presença de IgG1 e produção significativa de IL-4, IL-5 e IL-10. Este padrão de resposta determinou um efeito protetor discreto no desenvolvimento do T1D, caracterizado por diminuição do percentual de ilhotas com inflamação mais acentuada. Estes resultados mostram, portanto, que a infecção prévia com S. venezuelensis não impediu, de forma significativa, o desenvolvimento de insulite em modelo experimental de diabetes induzido por STZ

The cervical enamel projection (CEP) is an anatomic variation that can be found in the cement enamel junction, it´s recognition and early diagnosis improves outcome the tooth involved, allowing greater efficiency in treatment. The knowledge of the location, grade and incidence of CEP is decisive on prevention and treatment of periodontal disease. It were studied 1200 molars (600 mandibular molars and 600 maxillary molars) separated from the collection of teeth on the Discipline of Anatomy in FOSJCampos - UNESP. Each group of 600 teeth was separated from the second side (300 teeth) and the second type (first, second or third molar). Each tooth had thoroughly inspected the cervical region, in all their faces, in order to verify the incidence and the grade of CEP in each surface. It was found that the CEP covered in 278 (23,17%) teeth was 146 (52,52%) mandibular molars and 132 (47,48%) maxillary molars. The CEPs were concentrated on a tooth surface in 222 (79,86%) teeth, in two surfaces 53 (19,06%) teeth, and in three surfaces in three (1,08%) teeth. From the total of 4.800 surfaces examined the CEPs were found in 337 surfaces, and 228 (67,66%) surfaces of the grade I, 60 (17,8%) grade II and 49 (14,54%) grade III. The buccal surface presented 207 (61,42%) CEP, the lingual surface in 57 (16,91%), the mesial surface in 35 (10,39%) and the distal surface in 38 (11,28%) CEP. The results of this study demonstrated that the CEPs have focused more on the mandibular teeth on only one surface of the tooth, the grade I was the most found and the buccal surface the most involved

During the orthodontic correction planning in addition to dental-jaw correction, facial aesthetics is the orthodontist's and patient's major concern. To prevent facial aesthetics damage is really important to take into account the type of craniofacial growth: mesofacial (balanced), dolichofacial (vertical) or brachyfacial (horizontal). We evaluated 152 documentation files from the Department of Orthodontics of Dental University of Sao Jose dos Campos- UNESP in order to analyze what kind of growth occurs in most Class I malocclusions, Class II and Class III Angle of treated individuals from 6 to 12 years old. From the randomly collected samples, 15 of them belonged to Class I Angle malocclusions; 123 belonged to Angle Class II and 14 to Class III malocclusion. The results showed that in Class I, 66.67% were classified as dolicocephalic; in Class II, 64.23% were classified as dolicocephalic and in Class III, 50% were brachycephalic. We conclude that the dolichofacial was the type which ocurred the most, both in females and males and both in malocclusion Class I and Class II. The brachyfacial type most occurred in Class III malocclusion and the mesofacial type occurred in smaller numbers in the three malocclusions studied

In this work we study some topics of Celestial Mechanics, namely the problem of rigid body rotation and “spin-orbit” resonances. Emphasis is placed on the problem formulation and applications to some exoplanets with physical parameters (e.g. mass and radius) compatible with a terrestrial type constitution (e.g. rock) belonging to multiple planetary systems. The approach is both analytical and numerical. The analytical part consists of: i) the deduction of the equation of motion for the rotation problem of a spherical body with no symmetry, disturbed by a central body; ii) modeling the same problem by including a third-body in the planet-star system; iii) formulation of the concept of “spin-orbit” resonance in which the orbital period of the planet is an integer multiple of the rotation’s period. Topics of dynamical systems (e.g. equilibrium points, chaos, surface sections, etc.) will be included at this stage. In the numerical part simulations are performed with numerical models developed in the previous analytical section. As a first step we consider the orbit of the planet not perturbed by a third-body in the star-planet system. In this case the eccentricity and orbital semi-major axis of the planet are constants. Here the technique of surface sections, widely used in dynamical systems are applied. Next, we consider the action of a third body, developing a more realistic model for planetary rotation. The results in both cases are compared. Since the technique of disturbed surface sections is no longer applicable, we quantitatively evaluate the evolution of the characteristic angles of rotation (e.g. physical libration) by studying the evolution of individual orbits in the dynamically important regions of phase space, the latter obtained in the undisturbed case

Epilepsy is a chronic disorder that impairs life quality (LQ) and interferes in emotional, personal, social and family relationship aspects. This study evaluated 165 people with epilepsy diagnosis, ranging from 18 to 75 years old (M=41,28; SD= 13,26), by means of the QQV-65 (Life Quality Questionnaire with 65 questions) and investigated the association between the questionnaire scores and the disease features, comparing patients who showed refrectory seizures with patients with partially controled seizures. There was no difference in relation to the two groups regarding the LQ factor. The QQV-65 emotional factor was the most affected in both groups, since the estimated mean z-escore was 51,0±14,4 for Group I and 49,9±14,7 for Group II. Regarding the type of crisis, the analysis of variance (ANOVA) revealed that Health was the only factor in QQV-65 that showed a statistically significant difference between the z-scores (P = 0.024). However, for the frequency of epileptic seizures, except Health (P = 0.185), other factors QQV-65 proved to be related in a statistically significant way (P> 0.05). The research demonstrated that seizure control perception is quite important in the evaluation of life quality in all its aspects (health, body, society, emotion, locus of control, self-concept and cognition).

Destruction of bone and periodontal ligament as a result of periodontal disease can lead to anatomical defects in the furcation area. Treatment of these lesions is a major challenge to the clinician. Periodontal instruments have limited access to this area and plaque and calculus removal from root surfaces are extremely difficult. For proper treatment planning a number of factors must be taken into consideration to achieve immediate and long term success. Surgical therapy associated with bone grafts may be a viable option in the treatment of class II furcation defects, aiming to restore lost tissues. The aim of this paper is to report a clinical case where a simplified surgical approach with the use of autogenous graft was used to treat a class II furcation defect Twelve months after the surgery, an increase in clinical attachment level and pocket depth reduction resulted in a complete closure of the furcation lesion.
