The bark of Mimosa tenuiflora (Willd.) Poiret (Leguminosae family), popularly known as "jurema preta" in Brazil, is used by the population Contendas Sincorá (Bahia State, Brazil) for treatment coughs and wound healing. Thus, aim this study was to evaluate antinociceptive anti-inflammatory activities ethanol extract (EEMT) solvent soluble fractions (hexane—H, DCM—D, EtOAc—E BuOH—B) vivo. Additionally, we synthesized 5,7-dihidroxy-4'-methoxyflavanone (isosakuranetin) isolated compound...
Dental caries is a multifactorial chronic-infection disease, which starts with bacterial biofilm formation caused mainly by Streptococcus mutans. The use of probiotics has shown numerous health benefits, including in the fight against oral diseases. Strains Lactobacillus fermentum have already probiotic potential S. mutans, but there are still few studies. Thus, aim our study was to evaluate antimicrobial activity inoculum and metabolites produced L. TcUESC01 mutans UA159. For this, growth...
A monkey, after corpus callosum transection, will fail to recall through one hand tactual tasks that he has learned the other hand. However, if a monkey already task hand, destruction of does not greatly affect his subsequent It is concluded learning develops separate memory trace systems in both hemispheres.
Abstract Background Probiotics are important tools in therapies against vaginal infections and can assist traditional antibiotic restoring healthy microbiota. Recent research has shown that microorganisms belonging to the genus Lactobacillus have probiotic potential. Thus, this study evaluated potential vitro properties of three strains Lactiplantibacillus plantarum , isolated during fermentation high-quality cocoa, Gardnerella vaginalis Neisseria gonorrhoeae . Strains were for their...
PAPER INDUSTRY.The chemical analysis of the acetone, chloroform, toluene and methanol extracts a pitch sample was carried out by IR GC-MS, leading to identification sixty nine compounds, including fatty acids, alcohols hydrocarbons.Analysis acetone extractive eucalyptus wood used in Brazil for pulp production also out, resulting fifty mainly phenolic β-sitosterol other steroids.This showed that formation had contribution from extractives sources contamination.The results obtained methodology...
CHEMICAL CONSTITUENTS OF Bombacopsis glabra (BOMBACACEAE).The chemical study of the barks stem and roots (Bombacaceae) led to isolation identification 5-hydroxy-3,7,4'-trimethoxyflavone (1), 5hydroxy-3,6,7,4'-tetramethoxyflavone (2), naphtoquinone isohemigossypolone (3), ester triacontil p-coumarate (4) besides lupeol a mixture β-sitosterol stigmasterol.Their structures were elucidated by spectroscopic analysis, including IR, 1 H 13 C NMR MS.All these compounds, except 3, isolated for first...
The flavone 5-hydroxy-3,6,7,8,4'-pentamethoxyflavone (1) and the triterpenes lupenone, 9,19-cyclolanost-23-ene-3beta,25-diol (2), (24R)-9,19-cyclolanost-25-ene-3beta,24-diol (3) (24S)-9,19-cyclolanost-25-ene-3beta,24-diol (4) were isolated from hexane extract of stem bark Bombacopsis glabra (Bombacaceae). structures determined by 13C ¹H NMR (1D 2D) mass spectrometry, comparison with literature data for triterpenes. structure 1 was unambiguously confirmed a X-ray diffraction study. five...
This study investigates the biofilm formation, presence and distribution of virulence genes capacity to induce an inflammatory response in strains Staphylococcus aureus isolated from milk samples Bahia, Brazil. A total 132 raw were collected four dairy farms (designated D) located southwestern municipality Vitória da Conquista, October/2009 September/2010. After processing samples, 94 (71.2%) S. isolates obtained. These subjected antibiogram method MIC (Minimum Inhibitory Concentration). As...
Thirty-nine females from a normal strain of Drosophila willistoni were kept in bottles containing drop supernatant macerate "sex-ratio" the same species. Two these acquired condition and transmitted it to their progenies.
Abstract Deposits of wood extractives, commonly referred to as pitch, cause significant problems for the pulp and paper industries. The reduction these extractives is an important strategy aspect used minimize problems. present work studied effects storage time on amount variation chemical composition extracts, before after alkaline hydrolysis. Fatty acids, sterols, long-chain aliphatic alcohols, aromatic compounds were main classes substances found in all analyzed Hierarchical cluster...
Although stimulation of PRL secretion in the early postpartum period has been found to improve lactational performance, effect chronic maintenance elevated plasma levels on milk production is not known. In a randomized design, 66 lactating women were assigned receive either placebo (n = 32) or dopamine antagonist sulpiride 34; 100 mg, three times daily), for 4 days, followed by 50 daily, 90-day period). Their basal and 30 min postsuckling as well weights their infants measured 1, 4, 15, 30,...
In recent years, certain Lactobacillus sp. have emerged in health care as an alternative therapy for various diseases. Based on this, this study is aimed at evaluating vitro the potential probiotics of five lactobacilli strains isolated from pulp cupuaçu fruit fermentation against Gardnerella vaginalis and Neisseria gonorrhoeae. Our were classified safe use humans, they tolerant to heat pH. biofilm producers, while hydrophobicity autoaggregation varied 13% 86% 25%, respectively. The...
Abstract This study determines the optimal conditions for ultrasound‐assisted solid‐liquid extraction (UA‐SLE) of total phenolic compounds (TPC) Cenostigma macrophyllum leaves. The experiments were carried out according to three‐level, four‐variable Box‐Behnken design combined with response surface methodology (RSM). Extraction (sonication) time, liquid‐solid ratio, methanol concentration, and ultrasonic power investigated as independent variables obtain TPC. Data fitted a second‐order...
The stem barks and leaves of Cenostigma macrophyllum are used in Brazilian folk medicines the treatment stomach intestinal diseases. However, there no reports chromatographic methods to evaluate bioactives its standardized extracts for biological evaluation. An analytical method was developed validated simultaneous determination quantification bioactive phenolics gallic acid, methyl gallate, ellagic acid and, biflavonoids agathisflavone amentoflavone bark C. macrophyllum. HPLC operating...
Species of Staphylococcus are common in hospital infection (HI). Methicillin resistant S. aureus (MRSA) has also become a serious problem Brazilian HI. The aim this study was to characterize the pathogenicity methicillin-resistant and methicillin-sensitive (MSSA) isolated public hospitals. clinical isolates were obtained from intensive care unit. MRSA MSSA strains genotyped by PCR for detection genes related virulence factors. Moreover, tested biofilm formation cytokine induction...
