Prenatal diclofenac exposure delays pubertal development and induces behavioral changes in rats.

Diclofenac is a non-steroidal anti-inflammatory drug widely used by the general population and, although generally contraindicated during pregnancy, it is also used by some pregnant women. This study investigated endocrine, reproductive and behavioral effects of diclofenac in male and female offspring rats exposed in utero from gestational days 10-20. Pregnant rats were treated with diclofenac at doses of 0.

Resting time before slaughter restores homeostasis, increases rigor mortis time and fillet quality of surubim Pseudoplatystoma spp.

This study assesses the respiratory dynamics related to stress parameters and resting time before slaughter, in the quality of surubim (Pseudopatystoma spp.) fillets. A completely randomized design was conducted using five treatments: resting time before slaughter of 0, 2, 4, 8 and 24 hours, with 15 fish sampled per treatment.

In vitro and in vivo impact assessment of eco-designed CuO nanoparticles on non-target aquatic photoautotrophic organisms.

This work has assessed the impact of copper oxide nanoparticles (CuONPs), designed via green route, toward photosynthetic apparatus on aquatic photoautotrophic organisms. In order to filling knowledge gaps, in vitro and in vivo assays were performed, using cyanobacterial phycocyanin (C-PC) from Arthrospira platensis and Lemna valdiviana plants (duckweed), respectively. Impairment in light energy transfer became evident in C-PC exposed to CuONPs, giving rise to an increase of light absorption and a suppression of fluorescence emission.

The improvement of grape juice quality using - pectinase.

The effect of pectinolytic enzyme preparation (PEP) produced by the fungus --N31 (PEP-N31) on total phenolic content, concentrations of methanol and color of grape juice was studied. Positive results were found when PEP-N31 was used to extract phenolic compounds after the grapes had been blanched for 3 min and macerated for 1 h. The resulting juice had better yield, color characteristics and higher phenolic content (1637.

Anti-inflammatory and anti-arthritic activity in extract from the leaves of Eriobotrya japonica.

Ethnopharmacological Relevance: The Eriobotrya japonica (EJ) is a Chinese medicinal plant that is currently grown in Brazil. E. japonica leaves infusion is traditionally used in the treatment of inflammation; however, there are few scientific studies showing the effects of these properties on joint articular and persistent experimental inflammation.

Cerium catalyst promoted C-S cross-coupling: synthesis of thioethers, dapsone and RN-18 precursors.

In this work, we present a novel, efficient and green methodology for the synthesis of thioethers by the C-S cross-coupling reaction with the assistance of [Ce(l-Pro)2]2Ox as a heterogeneous catalyst in good to excellent yields. A scale-up of the protocol was explored using an unpublished methodology for the synthesis of a dapsone-precursor, which proved to be very effective over a short time. The catalyst [Ce(l-Pro)2]2Ox was recovered and it was shown to be effective for five more reaction cycles.

Rapid extraction method followed by a d-SPE clean-up step for determination of phenolic composition and antioxidant and antiproliferative activities from berry fruits.

Despite the numerous studies that have shown a wide range of biological activities to berry fruits, scientific data focusing on modern, rapid and simple extraction methods followed by a clean-up step is still lacking. Therefore, the present work was aimed at investigating the use of a fast one-step solid-liquid extraction procedure followed by a dispersive solid-phase extraction (d-SPE) clean-up step to evaluate the phenolic composition, antioxidant and antiproliferative activities from three of the principal berries found in Brazil, pomegranate (Punica granatum L.), blackberry (Rubus ulmifolius Schott.

Development of a Predictive Model to Induce Atherogenesis and Hepato-Renal Impairment in Female Rats.

Therapeutic approaches for the treatment of dyslipidemia and atherosclerosis have radically changed in recent decades. Part of this advance undeniably stems from basic biomedical research that has provided a better understanding and identification of new therapeutic targets. The aim of this work was to develop a model to induce atherogenesis and hepato-renal impairment in female Wistar rats.

Comparative Meta-Analysis of the Effect of Concentrated, Hydrolyzed, and Isolated Whey Protein Supplementation on Body Composition of Physical Activity Practitioners.

Whey protein (WP) is a dairy food supplement and, due to its effects on fat-free mass (FFM) gain and fat mass (FM) loss, it has been widely consumed by resistance training practitioners. This review analyzed the impact of WP supplementation in its concentrated (WPC), hydrolyzed (WPH) and isolated (WPI) forms, comparing it exclusively to isocaloric placebos. Random effect meta-analyses were performed from the final and initial body composition values of 246 healthy athletes undergoing 64.

Physical, ecological and human dimensions of environmental change in Brazil's Pantanal wetland: Synthesis and research agenda.

The Pantanal is the world's largest freshwater wetland, located in the geographical centre of South America. It is relatively well conserved, and features unique landscapes, ecosystems, and traditional cultural practices, shaped by the dynamic interaction of climatological, hydrological, geological, ecological, and anthropogenic factors. Its ecological integrity is increasingly threatened by human activities, particularly, in the wider catchment area, for example, deforestation, agricultural intensification, and construction of hydropower plants, with implications for local people's livelihoods.

Antiatherosclerotic Properties of (Cham. & Schltdl.) Micheli: From Antioxidant and Lipid-Lowering Effects to an Anti-Inflammatory Role.

is an important medicinal plant species that is native to South America. Despite extensive popular usage as a hypolipidemic drug, its effects as an atheroprotective agent remain unknown. The aim of this study was to evaluate the effects of an ethanol-soluble fraction that was obtained from (ESEG) leaves against the development of atherosclerosis in rabbits.

Psychotria leiocarpa Extract and Vincosamide Reduce Chemically-Induced Inflammation in Mice and Inhibit the Acetylcholinesterase Activity.

Species from Psychotria are used in folk medicine against inflammatory diseases, respiratory disturbances, and anti-hallucinogenic. In the present study, the compound vincosamide (PL-1) was identified for the first time in methanolic extract of the Psychotria leiocarpa (ME-PL) leaves, as well as the anti-inflammatory and anticholinesteric effects in rodents and molecular docking simulations. The fractionation of the chloroform fraction (CF-PL) through chromatographic methods afforded the known compound PL-1.

Looking beyond the skin: Cutaneous and systemic oxidative stress in UVB-induced squamous cell carcinoma in hairless mice.

Cumulative ultraviolet (UV) exposure is associated with squamous skin cell carcinoma. UV radiation induces oxidative modifications in biomolecules of the skin leading to photocarcinogenesis. Indeed, the cyclobutene pyrimidine dimers and other dimers formed by photoaddition between carbon-carbon bonds also have an important role in the initiation process.
