TL;DR: The aqueous extracts of soursop showed an antibacterial effect against S. aureus and V. cholerae, but the antibacterial activity by the ethanol extracts of this plant was not demonstrated.
Abstract: Antibacterial effects of aqueous and ethanolic extracts of seeds of moringa (Moringa oleifera) and pods of soursop (Annona muricata) in the concentration of 1:5 and 1:10 in volumes 50, 100, 150 and 200 microL were examined against Staphylococcus aureus, Vibrio cholerae, Escherichia coli (isolated from the organism and the aquatic environment) and Salmonella Enteritidis. Antibacterial activity (inhibition halo > 13 mm) against S. aureus, V. cholerae and E. coli isolated from the whiteleg shrimp, Litopenaeus vannmaei, was detected in aqueous and ethanolic extracts of moringa. E. coli isolated from tilapiafish, Oreochromis niloticus, was sensitive to the ethanolic extract of moringa. The aqueous extracts of soursop showed an antibacterial effect against S. aureus and V. cholerae, but the antibacterial activity by the ethanol extracts of this plant was not demonstrated.

TL;DR: The developed assay significantly improves rapid C. pseudotuberculosis detection and could supersede bacteriological culture for microbiological and epidemiological diagnosis of CLA.
Abstract: Corynebacterium pseudotuberculosis is the aetiological agent of caseous lymphadenitis (CLA), a debilitating disease of sheep and goats. Accurate diagnosis of CLA primarily relies on microbiological examination, followed by biochemical identification of isolates. In an effort to facilitate C. pseudotuberculosis detection, a multiplex PCR (mPCR) assay was developed targeting three genes of this bacterium: the 16S rRNA gene, rpoB and pld. This method allowed efficient identification of 40 isolates of this bacterium that had been identified previously by biochemical testing. Analysis of taxonomically related species did not generate the C. pseudotuberculosis mPCR amplification profile, thereby demonstrating the assay's specificity. As little as 1 pg of C. pseudotuberculosis genomic DNA was detected by this mPCR assay, demonstrating the sensitivity of the method. The detection limit in clinical samples was estimated to be 10(3) c.f.u. C. pseudotuberculosis could be detected directly in pus samples from infected sheep and goats (n=56) with a high diagnostic sensitivity (94.6 %). The developed assay significantly improves rapid C. pseudotuberculosis detection and could supersede bacteriological culture for microbiological and epidemiological diagnosis of CLA.

TL;DR: In this paper, a series of hydrogels were synthesized varying the percentage of CNWs (1, 2, 5, 10, and 20 ) and the amount of crosslinking agent (0.05, 0.15, and 0.20 ).

TL;DR: The main goal is to raise and identify the social-demographic and the gynecological profile of those young ladies, by identifying the reason which led them to pregnancy and by knowing their pereption of it.
Abstract: Tratou-se de pesquisa exploratorio-descritiva, realizada de outubro a dezembro de 2002, com 216 adolescentes gravidas assistidas pela Estrategia de Saude da Familia dos municipios pertencentes a Microrregiao de Saude de Acarau, Ceara. Objetivou caracterizar o perfil socio-demografico e gineco-obstetrico destas, identificando o motivo que as levou a engravidar, e saber como percebiam sua gravidez. A maior parte destas tinha 17 anos, eram pardas, alfabetizadas, donas-de-casa, tinham companheiro fixo e viviam com menos de um salario minimo. Destas, 32,4% menstruou aos 12 anos, 25% teve a primeira relacao sexual aos 16 anos e, 72,7% estava na primeira gestacao. Destaca-se o desejo de ser mae como principal motivo para engravidar, e a percepcao em relacao a gravidez esta relacionada com felicidade e realizacao pessoal.

TL;DR: A lectin from Vatairea macrocarpa Duke seeds (VML) was isolated using affinity chromatography on a guar gum column and size-exclusion chromatography indicated that VML is predominantly a dimeric protein, although tetramers and larger aggregates were also present.
