Accessibility of polycyclic aromatic hydrocarbon content in fishes from the region of the 2019 oil spill on the northeast Brazil coast.

In August 2019, Brazil experienced its largest large oil spill, which impacted extensive areas and significantly affected the northeastern region, particularly Pernambuco. Polycyclic aromatic hydrocarbons (PAHs), major oil components, are critical for assessing fish contamination risks. This study presents two sample pretreatment methods for fish samples - ultrasound-enhanced air-assisted liquid-liquid microextraction (UE-AA-LLME) for low molar mass PAHs, and matrix solid-phase dispersion for high molar mass PAHs - followed by a Gas-Chromatography coupled to Mass Spectrometry (GC-MS) detection.

Interrelation of Stress, Eating Behavior, and Body Adiposity in Women with Obesity: Do Emotions Matter?

Background/objectives: Obesity is influenced by biological, hormonal, and social factors, contributing to chronic diseases and burdening the healthcare system. Chronic stress and emotional eating are linked to weight gain, affecting eating behaviors and metabolism. This study aimed to assess the association between stress, eating behavior, and adiposity in obese women.

Chemical and sensorial profile of cultivars fermented by different post-harvest processing methods.

Climatic conditions, genotypes, and post-harvest processing methods influence coffee quality. Microbial fermentation during post-harvest processing has sparked researchers' interest due to the modulation of the sensory characteristics of coffee. However, the influence of microbial fermentation on different coffee genotypes has been little investigated.

IMPACT OF SARCOPENIA ON THE PROGNOSIS OF PATIENTS WITH CIRRHOSIS HOSPITALIZED FOR ACUTE DECOMPENSATION OR ACUTE-ON-CHRONIC LIVER FAILURE.

Background: Cirrhosis is a prevalent disease and ranks among the leading causes of death worldwide. Sarcopenia is believed to be associated with a poorer prognosis in patients with cirrhosis.

Objective: To evaluate the impact of sarcopenia on the prognosis of patients hospitalized for acute decompensation of cirrhosis, with or without acute-on-chronic liver failure.

Long-Range Supramolecular Assembly of a Pyrene-Derivatized Polythiophene/MWCNT Hybrid for Resilient Flexible Electrochromic Displays.

Organic electrochromic polymers hold great potential for integration into low-power flexible electrochromic displays (F-ECDs) due to their wide range of colors and simple processing. However, challenges such as inefficient charge transfer and degradation upon device integration hinder their practical applications. Herein, we report an innovative, general approach that utilizes template-induced supramolecular nanostructuring to engineer established electrochromic polymers, enhancing their performance and durability.
