O texto analisa o florescimento cultural brasileiro dos anos 60, como ele brotou do movimento contraditório da sociedade, e como ajudou a forjar setores sociais críticos da ordem estabelecida pela ditadura militar após 1964, alguns dos quais chegaram ao extremo da luta armada.

A epilepsia do lobo temporal (ELT) é a principal forma de epilepsia, e a principal lesão desenvolvida por pacientes com ELT é a esclerose mesial temporal (EMT) apresentando perda neuronal, gliose e atrofia da região do hipocampo. Os íons cálcio são fundamentais para o funcionamento de inúmeras vias metabólicas em todos os níveis fisiológicos e desempenham papel fundamental nas respostas de despolarização neuronal. Foi comprovado que a ativação tanto de receptores ionotrópicos quanto metabotrópicos de glutamato promove o influxo anormal de Ca2+ para o meio intracelular, potencializando o efeito de excitação associado à EMT. O cálcio atua tanto como mensageiro celular secundário, quanto primário através da interação com um receptor específico na superfície celular, o Receptor Sensor de Cálcio (CASR). O CASR é expresso em diversas regiões do cérebro, incluindo o hipocampo, no entanto são desconhecidas muitas das possíveis funções desempenhadas por este receptor no cérebro. Ele pertence à família de receptores acoplados a proteína-G, e exibe homologia significativa com os receptores metabotrópicos de glutamato (mGluRs). Ademais, os mGluRs regulam a expressão da família de proteínas ligantes de cálcio neuronal, da qual faz parte a proteína VILIP-1, associada especificamente com o fenômeno da plasticidade sináptica no cérebro. O objetivo deste projeto foi determinar a expressão das proteínas CASR, mGluR1 e VILIP-1 em tecidos de hipocampo de pacientes com epilepsia do lobo temporal comparando com a expressão de tecidos de indivíduos normais. Os três genes encontraram-se subexpressos nos tecidos de pacientes com ELT, sendo que os tecidos dos pacientes, em grau crônico da doença, justificam tais graus de expressão. Sugere-se uma possível interação entre CASR e mGluR1 e...(Resumo completo, clicar acesso eletrônico abaixo)

There are no studies investigating the role of nutritional status and immunity associated with Jorge Lobo's disease. The objective of this study was to evaluate the effects of protein-calorie malnutrition on the immune response of BALB/c mice inoculated with Lacazia loboi. In this study,the animals were divided into four groups: G1: inoculated with restricted diet, G2: not inoculated with restricted diet, G3: inoculated with regular diet, G4: not inoculated with regular diet. The animals of groups G1 and G2 were submitted to malnutrition for 20 days and once installed the animals were inoculated intradermally into the footpad. After 4 months, they were euthanised for the isolation of peritoneal lavage cells and removal of the footpad. The production of IL-2, IL-4, IL-10, IL-12, IFN-γ, TNF-α, H2 O2 and nitric oxide (NO) was evaluated in the peritoneal lavage cells. The footpad was evaluated regarding the size of macroscopic lesions, number of fungi and viability index. The results showed that the infection did not exert great influence on the body weight of the mice and previous malnutrition was an unfavourable factor for viability index, number of fungi, macroscopic lesion size in the footpad and production of H2 O2 , NO, IL-12, IL-10 and IFN-γ, suggesting that malnutrition significantly altered fungal activity and peritoneal cells. The results suggest considerable interaction between nutrition and immunity in Jorge Lobo's disease.

The objective of the research was to define the classes of use capacity of 2403.25 ha in the basin of the Corriente del Lobo - Itatinga (SP), (22°03'56" to 22°59'12" of latitude S and 48°38'47" to 48°41'25" of longitude W Gr.). The soil use capacity was obtained by using the SIG IDRISI 32 crossing the documents of steepness and soils and the document of judgment of classes of soil use capacity and of the utilitarian rising of the physical milieu. The classes and subclasses areas of use capacity presented the following values: IIIa - 68.60 ha (2.85%), IIIe,s - 1919.15 ha (79.86%); IIIe - 210.60 ha (8.76%); IVe - 3.38ha (0.14%); IVe,s - 157.42 ha (6.55%) and VIe,s - 44.10 ha (1.84%). The lands of the basin were distributed in three classes (III, IV and VI) and six subclasses but the biggest extension (79.9%) belonged to the subclass IIIe,s. The modules of the IDRISI allowed to discriminate, mapping and to quantify quickly the soil use capacity of the areas of classes and subclasses in the basin.

Introduction: Prebiotics positively affect gut microbiota composition, thus improving gut function. These properties may be useful for the treatment of constipation. Objectives: This study assessed the tolerance and effectiveness of a prebiotic inulin/partially hydrolyzed guar gum mixture (I-PHGG) for the treatment of constipation in females, as well as its influence on the composition of intestinal microbiota and production of short chain fatty acids. Methods: Our study enrolled 60 constipated female health worker volunteers. Participants reported less than 3 bowel movements per week. Volunteers were randomized to treatment with prebiotic or placebo. Treatment consisted of 3 weeks supplementation with 15 g/d I-PHGG (fiber group) or maltodextrin (placebo group). Abdominal discomfort, flatulence, stool consistency, and bowel movements were evaluated by a recorded daily questionnaire and a weekly interview. Changes in fecal bacterial population and short chain fatty acids were assessed by real-time PCR and gas chromatography, respectively. Results: There was an increased frequency of weekly bowel movements and patient satisfaction in both the fiber and placebo groups with no significant differences. Total Clostridium sp significantly decreased in the fiber group (p = 0.046) and increased in the placebo group (p = 0.047). There were no changes in fecal short chain fatty acid profile. Conclusions: Consumption of I-PHGG produced clinical results comparable to placebo in constipated females, but had additional protective effects on gut rnicrobiota by decreasing the amount of pathological bacteria of the Clostridium genera.
