Hydrochemical relationships in groundwater from central São Paulo State, Brazil

Groundwater samples from different aquifers occurring at center/northeast portion of São Paulo State, Brazil, were collected and chemically analyzed. The waters leaching Mesozoic sediments are generally more acid (pH(average) = 5.9) and have lower values for total dissolved solids (TDSaverage = 105 mg/L) than those obtained for waters leaching Paleozoic sediments of Tubarao Group. First-degree trend surfaces revealed that the deeper tubular wells occur towards east/southeast and exploit Paleozoic sediments as well fractured/fissured diabases/basalts, whereas the tubular wells in the west/northwest region are shallower. Piper diagrams indicated that the majority of the waters are a blend of waters from different lithologies. Significant correlations were found among nitrate, chloride and bicarbonate, suggesting the occurrence of some anthropogenic inputs, whereas elevated alpha activity of geogenic Ra-226 indicated the need of a broad radiometric survey in the area.

Phytosociological study of the tree stratum of a semideciduous mesophytic forest in the municipality of Botucatu, SP, Brazil

The phytosociological structure was studied in an area of semideciduous mesophytic forest lied on the ascent of the Cuesta of Botucatu. Once the relief of the area was very heterogeneous, the forest, for the sampling process, was divided in three sampling regions: the upper one (on the plateau), the middle one (on the ascent properly said) and the lower one (on the plain). Through the point-centered method, 1224 (408 in each region) trees were sampled. For this work, only the trees with shaft equal or higher than 1.30m high were considered. The three sampling regions showed some interesting differences in regard to the phytosociologic structure. Once there are differences among the soil of the three regions, the variations in the structure must be connected to the differences in the soil.

Prevalence and associated factors for suicidal ideation and behaviors in obsessive-compulsive disorder

Introduction: Patients with obsessive-compulsive disorder (OCD) have historically been considered at low risk for suicide, but recent studies are controversial. Objective: To study the prevalence of suicidal thoughts and attempts in OCD patients and to compare those with and without suicidality according to demographic and clinical variables. Methods: Fifty outpatients with primary OCD (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition) from a Brazilian public university were evaluated. The Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) was used to assess OCD severity, the Beck Depression Inventory to evaluate depressive symptoms and the Alcohol Use Disorders Identification Test to assess alcohol problems. Results: All patients had obsessions and compulsions, 64% a chronic fluctuating course and 62% a minimum Y-BOCS score of 16. Half of the patients presented relevant depressive symptoms, but only three had a history of alcohol problems. Seventy percent reported having already thought that life was not worth living, 56% had wished to be dead, 46% had suicidal ideation, 20% had made suicidal plans, and 10% had already attempted suicide. Current suicidal ideation occurred in 14% of the sample and was significantly associated with a Y-BOCS score ≥16. Previous suicidal thoughts were associated with a Beck Depression Inventory score ≥19. Conclusion: Suicidally has been underestimated in OCD and should be investigated in every patient, so that appropriate preventive measures can be taken.

Estudo fitoquímico preliminar e bioensaio toxicológico frente a larvas de Artemia salina Leach. de extrato obtido de frutos de Solanum lycocarpum A. St.-Hill (Solanaceae)

The phytochemical profile of ethanolic extract of Solanum lycocarpum fruits was analyzed and preliminary toxicity tests were performed against brine shrimp larvae. The extract was subjected to preliminary phytochemical analysis to identify the main classes of secondary metabolites and tested against the larvae of A. salina to obtain the median lethal concentrations (LC50%). The phytochemical tests showed the presence of phenols, tannins, saponins, alkaloids and free steroids. The extract was fractionated with various solvents for toxicity testing against the larvae and the hydroalcoholic fraction showed considerable cytotoxicity (CL50% = 285.546 g/mL).

Estrutura populacional de Oeceoclades maculata Lindl. (Orchidaceae), em um mosaico vegetacional (FEENA) da Floresta Estadual Edmundo Navarro de Andrade, Rio Claro, São Paulo

O objetivo do presente estudo foi avaliar a estrutura de população de O. maculata, através de sua distribuição espacial e estrutura de habitat, comparando características físicas e biológicas em diferentes fisionomias de Pinus spp. e Eucalyptus spp.. Foram montadas 86 parcelas de 5m por 10m, distribuídas uniformemente entre 4 áreas pré-estabelecidas de fisionomias distintas. Os indivíduos levantados foram separados em duas classes etárias, jovens e adultos, e contabilizou-se a taxa de predação, número de pseudobulbos e número de folhas. Os parâmetros ambientais avaliados foram cobertura herbácea, densidade de dossel, luminosidade e umidade de serrapilheira. A espécie apresentou densidades bastante elevadas nas áreas de plantios de eucalipto (1224 e 1733 indivíduos por hectare) e baixas nos plantios de pinus (88 e 26 individuos por hectare) o que levou as análises a se concentrarem nas fisionomias compostas por eucaliptos. O padrão de distribuição da espécie foi o agregado em todos os ambientes. Indivíduos adultos apresentaram significativamente um número médio de pseudobulbos maior que indivíduos jovens (Mann-Whitney; U = 24248.500; p<0,001), porém a diferença no número de folhas não foi significativa. A taxa de predação foliar em O. maculata entre as áreas de eucaliptos apresentou variação significativa. A variação do total de folhas predadas foi confirmada pelo teste Qui-quadrado de Pearson (X²=115.487; gl=1; p<0.001). A comparação de médias, com base no teste de Kruskal-Wallis, para cobertura de dossel (H(3,N=102)=28,534 p<0,001) e cobertura herbácea H(3,N=94)=28,246, p<0,001, mostrou taxas menores nas áreas de eucalipto. A umidade da serrapilheira foi menor (36,5%) nos locais onde a espécie apresentou agrupamentos, quando comparada aos locais de ausência (47,5%). Oeceoclades maculata Lindl. possui grande capacidade para colonizar ambientes... (Resumo completo, clicar acesso eletrônico abaixo)
