[Performance of the "a body shape index" as a discriminator of obesity and sarcopenic obesity - ELSA-Brasil].

The scope of this study was to determine the diagnostic performance of ABSI for obesity and sarcopenic obesity, compared to the results of bioimpedance analysis (BIA) and BMI, by sex and age group. It involved a cross-sectional study with 12,793 participants in the second round of ELSA-Brasil (Longitudinal Study of Adult Health in Brazil), which obtained measurements of body fat percentage using BIA and anthropometry, verifying the performance of the diagnostic tests in order to compare the indices. The results showed that for obesity in men in all three age groups, the sensitivity was below 49%.

Proportional mortality and years of potential life lost due to liver diseases among agricultural workers, Brazil, 2017 to 2022.

This study aimed to describe the profile and calculate the years of potential life lost (YPLL) due to liver diseases in Brazilian agricultural workers from 2017 to 2022. For this, we analyzed microdata available in the Brazilian Mortality Information System considering the underlying cause of death with codes K70-K77 (International Classsification of Disease, 10th revision - ICD-10) as the outcome of interest. Workers' profile was characterized according to sociodemographic variables and Brazilian regions, forming a comparison group with all other Brazilian workers aged from 18-69 years who died in the same period and from the same underlying cause.

Simultaneous Unbinned Differential Cross-Section Measurement of Twenty-Four Z+jets Kinematic Observables with the ATLAS Detector.

Z boson events at the Large Hadron Collider can be selected with high purity and are sensitive to a diverse range of QCD phenomena. As a result, these events are often used to probe the nature of the strong force, improve Monte Carlo event generators, and search for deviations from standard model predictions. All previous measurements of Z boson production characterize the event properties using a small number of observables and present the results as differential cross sections in predetermined bins.

Iron-associated lipid peroxidation in Alzheimer's disease is increased in lipid rafts with decreased ferroptosis suppressors, tested by chelation in mice.

Introduction: Iron-mediated cell death (ferroptosis) is a proposed mechanism of Alzheimer's disease (AD) pathology. While iron is essential for basic biological functions, its reactivity generates oxidants which contribute to cell damage and death.

Methods: To further resolve mechanisms of iron-mediated toxicity in AD, we analyzed post mortem human brain and ApoEFAD mice.

Preclinical Toxicological Assessment of 2-(Benzoxazol-2-yl)[(2-hydroxynaphthyl)diazenyl]phenol Derivatives for Blue Light and UV Radiation Photoprotection Applications.

The widespread use of electronic devices has led to increased blue light exposure, highlighting the need for effective radiation blockers with blue light protection. Two synthetic 2-(2'-hydroxyphenyl)benzoxazole derivatives named azo-4'-benzoxazole and azo-5'-benzoxazole have shown an unprecedented blue light absorption capacity but had not been subjected to a safety evaluation. This study aimed to evaluate the cytotoxic, genotoxic, and mutagenic activities of these compounds.
