Associação entre classe econômica e estresse na ocorrência da disfunção temporomandibular

Objetivou-se neste estudo verificar a associação da classe econômica e do estresse com a ocorrência de disfunção temporomandibular (DTM). A população deste estudo constituiu-se de uma amostra estatisticamente significativa de 354 indivíduos de ambos os sexos, pertencentes a diferentes classes econômicas da zona urbana do município de Piacatu, São Paulo, Brasil. Para isso, utilizou-se o Critério de Classificação Econômica Brasil (CCEB) para a estratificação econômica da população. Retirou-se uma amostra de cada estrato, na qual aplicou-se o Questionário de Fonseca para verificar o grau de DTM, e a Escala de Reajustamento Social (SRRS) para verificar o grau de estresse. Os dados coletados foram tabulados por meio do programa Epi Info 2000, versão 3.2, e analisados estatisticamente por meio do Teste Qui-Quadrado, com nível de significância de 5%. Os chefes das famílias foram assim distribuídos: 4 famílias pertencentes à Classe A2, 14 à Classe B1, 25 à Classe B2, 112 à Classe C, 174 à Classe D e 25 à Classe E. Após a análise estatística não foi observada associação significativa entre classe econômica e disfunção temporomandibular (DTM); entretanto, a mesma ocorreu entre estresse e DTM (p<0,01). A classe econômica não influencia na ocorrência de DTM, mas existe associação direta entre estresse e disfunção temporomandibular.

Avaliação e monitoramento da obesidade em adultos residentes do município de Rio Claro - SP

Obesity is characterized by an excess of fat on the body and can results several problems on the individual health. As an epidemic of modern times, the prevalence started to increase at an accelerated rate from the 90's in worldwide. Data on the epidemic in Brazil and medium-sized cities are scarce, and the monitoring of obesity is essential for development public policy. So, the objective was to analyze the individual factors associated with obesity such as age, gender, education, marital status, economic class and level of physical activity and make a monitoring of obesity in adults in the city of Rio Claro - SP. To do this, the survey was conducted longitudinally, consists of two times at an interval of seven years. At first (2008) were interviewed 1588 adults in the city of Rio Claro distributed throughout the city. At the second phase (2014/2015) was conducted a new interview with the same subject in 1588. In 2008, personal information collected and applied some questionnaires with the physical activity level, food intake and quality of life. To assess obesity in adults was calculated the body mass index (BMI) proposed by the World Health Organization (WHO) from the high reported weight and height. For older people it used a specific BMI. The prevalence was used percentages and their respective confidence intervals of 95%. For the incidence, was calculated by the formula of cumulative incidence, both stratified by personal characteristics (gender, economic class, education, marital status and age). Thus it was observed that there was an increase in the prevalence of obesity in 2008 (19.0%), increasing to 26.7% in 2015. The cumulative incidence was 14.4% in the range of 7 years. As for the groups, we observed a significant difference between economic class and obesity being less prevalent among people of class D / E. Regarding marital status, it was observed that married / cohabiting have a higher prevalence. Therefore, we can conclude...

Crystallization and preliminary X-ray diffraction analysis of a class II phospholipase D from Loxosceles intermedia venom

Structure of a novel class II phospholipase D: Catalytic cleft is modified by a disulphide bridge

Phospholipases D (PLDs) are principally responsible for the local and systemic effects of Loxosceles envenomation including dermonecrosis and hemolysis. Despite their clinical relevance in loxoscelism, to date, only the SMase I from Loxosceles laeta, a class I member, has been structurally characterized. The crystal structure of a class II member from Loxosceles intermedia venom has been determined at 1.7. Å resolution. Structural comparison to the class I member showed that the presence of an additional disulphide bridge which links the catalytic loop to the flexible loop significantly changes the volume and shape of the catalytic cleft. An examination of the crystal structures of PLD homologues in the presence of low molecular weight compounds at their active sites suggests the existence of a ligand-dependent rotamer conformation of the highly conserved residue Trp230 (equivalent to Trp192 in the glycerophosphodiester phosphodiesterase from Thermus thermophofilus, PDB code: 1VD6) indicating its role in substrate binding in both enzymes. Sequence and structural analyses suggest that the reduced sphingomyelinase activity observed in some class IIb PLDs is probably due to point mutations which lead to a different substrate preference. © 2011 Elsevier Inc.

Structural insights into substrate binding of brown spider venom class II phospholipases D

Phospholipases D (PLDs), the major dermonecrotic factors from brown spider venoms, trigger a range of biological reactions both in vitro and in vivo. Despite their clinical relevance in loxoscelism, structural data is restricted to the apo-form of these enzymes, which has been instrumental in understanding the functional differences between the class I and II spider PLDs. The crystal structures of the native class II PLD from Loxosceles intermedia complexed with myo-inositol 1-phosphate and the inactive mutant H12A complexed with fatty acids indicate the existence of a strong ligand-dependent conformation change of the highly conserved aromatic residues, Tyr 223 and Trp225 indicating their roles in substrate binding. These results provided insights into the structural determinants for substrate recognition and binding by class II PLDs.

Crystallization and preliminary X-ray diffraction analysis of a eumenine mastoparan toxin: a new class of mast-cell degranulating peptide in the wasp venom

Mastoparans are tetradecapeptides found to be the major component of vespid venoms. A mastoparan toxin isolated from the venom of Anterhynchium flavomarginatum micado has been crystallized and X-ray diffraction data collected to 2.7 Angstrom resolution using a synchrotron-radiation source. Crystals were determined to belong to the space group P6(2)22 (P6(4)22). This is the first mastoparan to be crystallized and will provide further insights into the conformational significance of mastoparan toxins with respect to their potency and activity in G-protein regulation.

Evolução e mapeamento do uso da terra, através de imagens aerofotogramétricas e orbitais em Santa Bárbara D'Oeste (SP)

Em Santa Bárbara D'Oeste,SP, foram realizados dois mapeamentos do uso da terra em área de 14.625 ha. No primeiro utilizou-se fotografias aéreas verticais pancromáticas (data de 25/6/78), na escala 1:35.000, e no segundo utilizou-se imagens orbitais do satélite LANDSAT-5 com sensor Thematic Mapper (data de 12/8/91), escala 1: 100.000, nas bandas 3, 4 e 5 e composição colorida 3/4/5. Para auxiliar a confecção desses mapas, obteve-se chaves de interpretação, tanto para as aerofotos como para as imagens orbitais. As fotografias aéreas proporcionaram um maior nível de detalhamento na identificação do uso da terra. A banda 3 e a composição colorida 3/4/5 foram as mais eficientes entre as imagens orbitais. Entre 1978 e 1991, a área de ocorrência de cana-de-açúcar permaneceu a mesma, as áreas de mata e pastagem diminuíram, enquanto que as áreas de reflorestamento e urbana aumentaram. Essa região teve sua capacidade de uso enquadrada, na maior parte, na classe IV: terras mais apropriadas para pastagens ou plantas perenes como a cana-de-açúcar, devendo-se aplicar técnicas intensivas de conservação, e com aptidão baseada em práticas agrícolas que refletem um alto nível tecnológico.

Menstrual irregularity: a possible clinical marker of metabolic dysfunction in women with class III obesity

Purpose. To evaluate whether menstrual irregularity in morbidly obese women is indicative of metabolic dysfunction.Patients and Methods. Fifty-seven women with morbid obesity were evaluated. They were divided into two groups: one comprising women without menstrual dysfunctions or hirsutism (Group 1), and another obese women showing menstrual dysfunction with or without hirsutism (Group 2). The following were evaluated: age, colour, childbirth, marital status, profession, socio-economic level, education, age at menarche, body weight, height, body mass index, presence of hirsutism (Ferriman Gallwey Index), abdominal circumference, hip circumference, waist-to-hip ratio, menstrual cycle, blood pressure, presence of acanthosis nigricans, insulin resistance (IR), fasting glycaemia, total cholesterol, HDL-C, LDL-C, triglycerides, thyroid-stimulating hormone, free T4, luteinising hormone (LH), follicle-stimulating hormone, prolactin, total testosterone, dehydroepiandrosterone sulfate, insulin and the Homeostasis Model Assessment (HOMA test).Results. Clinical and epidemiological aspects did not present statistical differences. Clinical and laboratory parameters did not show statistically significant alterations; however, HOMA test values for Group 2 were significantly higher than those for Group 1.Conclusions. The presence of IR in class III obese women can cause menstrual dysfunctions such as amenorrhoea or oligomenorrhoea even in the absence of hyperandrogenism, suggesting that IR plays an important role in the ovarian mechanisms involved in the menstrual cycle control.

Typing class I HLA-A gene using a nested PCR-RFLP procedure

In order to detect several new HLA-A class I alleles that have been described since 1998, the original PCR-RFLP method developed to identify the 78 alleles recognized at that time at high resolution level was adapted by us for low and medium resolution levels using a nested PCR-RFLP approach. The results obtained from blood samples of 23 subjects using both the PCR-RFLP method and a commercial kit (MicroSSP1A®, One Lambda Inc.) showed an agreement higher than 95%. The PCR-RFLP adapted method was effective in low and medium resolution histocompatibility evaluations.
