Effects of time-of-day on the noradrenaline, adrenaline, cortisol and blood lipidome response to an ice bath.

While the effect of time-of-day (morning versus evening) on hormones, lipids and lipolysis has been studied in relation to meals and exercise, there are no studies that have investigated the effects of time-of-day on ice bath induced hormone and lipidome responses. In this crossover-designed study, a group of six women and six men, 26 ± 5 years old, 176 ± 7 cm tall, weighing 75 ± 10 kg, and a BMI of 23 ± 2 kg/mhad an ice bath (8-12 °C for 5 min) both in the morning and evening on separate days. Absence from intense physical exercise, nutrient intake and meal order was standardized in the 24 h prior the ice baths to account for confounders such as diet or exercise.

Endothelial-specific deletion of connexin 43 improves renal function and structure after acute kidney injury.

Background: We have previously reported that the gap junction protein connexin 43 (Cx43) was upregulated in chronic renal disease in humans and rodents and plays a crucial role in the progression of experimental nephropathy. In this study, we investigated its role after renal ischemia/reperfusion (rIR), which is a major mechanism of injury in acute renal injury (AKI) and renal transplant graft dysfunction.

Methods: Wild-type mice (WT) and mice in which Cx43 expression was genetically reduced by half (Cx43 ±) were unilaterally nephrectomized.

Spatial distribution of atmospheric pollutants and fire outbreaks in the Pantanal biome from 2016 to 2021.

Pantanal fires have a significant impact on the environment. Anthropogenic emissions of residual gases have changed the tropospheric composition in this region due to burning. This study aims to analyze the spatial patterns of atmospheric pollutants (including carbon monoxide (CO), nitrogen dioxide (NO2), black carbon (BC), organic carbon (OC) and sulfur dioxide (SO2) and aerosol optical depth, along with fire outbreaks across the Pantanal biome from 2016 to 2021.

[Advances in continuous glucose monitoring: evidence of a new generation technology].

Continuous glucose monitoring (CGM) provides comprehensive and dynamic information to guide the management of diabetes mellitus (DM). This paper summarizes the evidence and implications of the use of the new CGM system, FreeStyle Libre 2 (FSL2). A global review of the literature on the use of FSL2 in people with DM was performed.
