Departamento de Bioquímica e Imunologia, Instituto de Ciências Biológicas, Universidade Federal de Minas Gerais, Belo Horizonte, Brazil.

The innate immune system promptly detects and responds to invading pathogens, with a key role played by the recognition of bacterial-derived DNA through pattern recognition receptors. The Z-DNA binding protein 1 (ZBP1) functions as a DNA sensor inducing type I interferon (IFN) production, innate immune responses and also inflammatory cell death. ZBP1 interacts with cytosolic DNA via its DNA-binding domains, crucial for its activation.

Synthetic data have emerged as an attractive option for developing machine-learning methods in human neuroimaging, particularly in magnetic resonance imaging (MRI)-a modality where image contrast depends enormously on acquisition hardware and parameters. This retrospective paper reviews a family of recently proposed methods, based on synthetic data, for generalizable machine learning in brain MRI analysis. Central to this framework is the concept of domain randomization, which involves training neural networks on a vastly diverse array of synthetically generated images with random contrast properties.

Variability of in buffaloes.

Front Genet

January 2025

Escola de Medicina Veterinária e Zootecnia, Universidade Federal da Bahia (UFBA), Salvador, Bahia, Brazil.

The buffalo population raised in Brazil tend to show loss of genetic variability over generations, with significant estimates of inbreeding depression. Besides mating genetically distant individuals, other tools can be used to maintain/increase the genetic variability of the population, such as the use of genotypes. The gene promotes the creation of crossing-over points across the genome, with each allele promoting the creation of a different hotspot.

This study aimed to compare the conventional soybean ( L.) cultivation method with integrated systems in an Latossolo Vermelho Acriférrico típico and how these systems affect soil cover biomass production, initial nutrient concentration in plant residues, soil respiration and microclimate, as well as soybean growth, physiology and productivity. A comparative analysis of microclimate and soil respiration, plant physiology, and growth was conducted between a conventional soybean monoculture (soybean grown without plant residues on the soil from the previous crop) and soybean grown in soil containing maize residues.

Injectable biomaterials, such as thermosensitive chitosan (CH)-based hydrogels, present a highly translational potential in dentistry due to their minimally invasive application, adaptability to irregular defects/shapes, and ability to carry therapeutic drugs. This work explores the incorporation of azithromycin (AZI) into thermosensitive CH hydrogels for use as an intracanal medication in regenerative endodontic procedures (REPs). The morphological and chemical characteristics of the hydrogel were assessed by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), and Fourier transform infrared spectroscopy (FTIR).

This research investigated the influence of the microencapsulation of phenolic compounds (PCs) from organic coffee husk with whey protein concentrate (WPC) and maltodextrin on the abundance of intestinal bacterial populations and their metabolic activity during in vitro fecal fermentation. The microencapsulated PCs were gradually metabolized during fecal fermentation, resulting in significant transformations and an increase in PCs in the fermentation media. The metabolism of PCs by the fecal microbiota occurred concurrently with the consumption of sugars, production of organic acids, and reduction in pH in the media.

In response to the rise of Non-communicable Diseases, public policies, such as Front-of-package (FOP) nutrition labeling, have been implemented to clarify information on food labels and promote healthier eating habits. Brazil adopted black magnifier warning label in 2020, which consists of a black rectangle with a magnifier glass followed by the expression "High in" for three critical nutrients: added sugar, saturated fat and/or sodium. This study aims to evaluate the effect of black magnifier warning label, brand, and claims on Brazilian consumers' perceived healthiness.
