Experimental setup for labyrinth seals: Pressure, temperature, mass flow rate, rotation velocity, and pressure drop simultaneous measurement.

Labyrinth seals (LSs) in turbomachinery are used to minimize leaks. This study presents an experimental setup designed to test and validate LS designs. The test bench (TB) described in this paper can evaluate different LS designs obtained through various methods to find better solutions to mitigate greenhouse gas (GHG) emissions.

Abortion-related complications in Brazil: results from the World Health Organization Multi-country Survey on Abortion (MCS-A).

This study aimed to describe the severity of abortion-related complications, factors associated with complications, the types of management and the experience of care in Brazil. A cross-sectional study in twenty hospitals (10 in Federal District, 3 in Rondônia and 7 in Maranhão). For 3 months, all women treated for abortion/miscarriage had their data collected.

Morbidity and factors associated with frailty in post-COVID-19 elderly patients attended at a reference center.

Objective: To assess the morbidity profile and identify factors associated with frailty syndrome in post-COVID-19 elderly patients treated at the only Reference Center for Elderly Health Care in northern Minas Gerais.

Methods: This is a case series study, utilizing the Clinical-Functional Vulnerability Index-20 (CFVI-20) and Comprehensive Geriatric Assessment (CGA) to characterize and evaluate the health condition of the group. To define the variables associated with frailty, a multivariate analysis was conducted.

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.
