Ovarian stimulation of Nelore calves and prepubertal heifers with a long-acting recombinant human FSH (corifollitropin-alpha) and subsequent ovum pick-up and in vitro embryo production outcomes.

The aim of this study was to evaluate the use of a long-acting recombinant human FSH (rhFSH, corifollitropin-alpha) to induce ovarian stimulation in Nelore breed (Bos indicus) calves and prepubertal heifers prior to ovum pick-up (OPU) for in vitro embryo production (IVEP). In Experiment 1, a dose-response trial was performed to determine the optimal dose of rhFSH, which was determined to be 10 μg. In Experiment 2, 6-7 mo old calves were randomly allocated to receive rhFSH either via sc (n = 5) or im (n = 5).

The Impact of Cholecystectomy on the Metabolic Profile of Patients Previously Submitted to Bariatric Surgery.

Purpose: To evaluate the influence of late cholecystectomy following bariatric surgery on the postoperative evolution of weight loss and biochemical, metabolic, and micronutrient parameters.

Methods: A retrospective study that assessed 86 patients who underwent cholecystectomy after at least 18 months of bariatric surgery. The analyzed variables included demographic data, comorbidities, weight loss, and biochemical, metabolic, and micronutrient parameters.

Minocycline inhibits microglial activation in the CA1 hippocampal region and prevents long-term cognitive sequel after experimental cerebral malaria.

Cerebral malaria is the worst complication of malaria infection, has a high mortality rate, and may cause different neurodysfunctions, including cognitive decline. Neuroinflammation is an important cause of cognitive damage in neurodegenerative diseases, and microglial cells can be activated in a disease-associated profile leading to tissue damage and neuronal death. Here, we demonstrated that treatment with minocycline reduced blood-brain barrier breakdown and modulated ICAM1 mRNA expression; reduced proinflammatory cytokines, such as TNF-α, IL-1β, IFN-γ, and IL-6; and prevented long-term cognitive decline in contextual and aversive memory tasks.

Evaluation of Bioactive Compounds and Antioxidant and Cytotoxic Effects of Oil and Pulp without Açaí Fat () Obtained by Supercritical Extraction.

For bioactivity studies, it is necessary to use products with a high degree of purity, which may influence the cytotoxic effects. Supercritical technology presents itself as an alternative to obtain these products. Therefore, the objective of this work was to obtain the bioactive compounds of oil and pulp of açaí fat-free supercritical technology and evaluate the cytotoxicity of products in MRC-5 and VERO cells in vitro.
