Aim: The purpose of this study was to investigate the relationship between the findings from liver biopsy and the serum angiotensin-converting enzyme (ACE) level to determine whether ACE might serve as a potential noninvasive sign of necroinflammatory activity in patients with Chronic Hepatitis B (CHB) infection.
Methods: A total of 54 CHB patients referred for liver biopsy were enrolled in the study. Serum ACE levels were determined photometrically with a kinetic test.
Results: The aspartate aminotransferase (AST), alanine aminotransferase (ALT), hepatitis B virus-deoxyribonucleic acid (HBV-DNA), histological activity index (HAI), and white blood cell counts were higher in patients with severe fibrosis, while albumin levels were low. The serum ACE levels showed a statistically significant correlation with HBV-DNA, HAI score, and ALT-AST levels.
Discussion: In this study, a statistically significant relation between serum ACE levels and HAI scores was observed. This represents the first analysis to compare necroinflammation of the liver and serum ACE levels. There may be some explanations that the suppression of hepatocyte growth factor (HGF) by Angiotensin II and increased inflammatory damage might be a reason for the correlation between HAI and ACE. Serum ACE levels, HBV-DNA levels, and serum transaminase levels might be used together as noninvasive markers for the prediction of necroinflammation in CHB patients.

Are abnormalities in lipid metabolism, together with adverse childhood experiences, the silent causes of immune-linked neurotoxicity in major depression?
Neuro Endocrinol Lett

Sichuan Provincial Center for Mental Health, Sichuan Provincial People's Hospital, School of Medicine, University of Electronic Science and Technology of China, Chengdu 610072, China.
Background: Severe or recurring major depression is associated with increased adverse childhood experiences (ACEs), heightened atherogenicity, and immune-linked neurotoxicity (INT). Nevertheless, the interconnections among these variables in outpatient major depression (OMDD) have yet to be determined. We aim to determine the correlations among INT, atherogenicity, and ACEs in OMDD patients compared to normal controls.

Aim: This study aimed to evaluate the association between serum calcium level and the risk of acute kidney injury (AKI) in patients with subarachnoid hemorrhage (SAH).
Methods: In this retrospective cohort study, data on adults from the Medical Information Mart for Intensive Care (MIMIC-III and MIMIC-IV) databases, spanning from 2008 to 2019, were extracted. In the logistic regression models, confounding variables, including age, white blood cell (WBC), systolic blood pressure (SBP), heart rate, blood urea nitrogen (BUN), glucose, international normalized ratio (INR), and the Charlson Comorbidity Index (CCI), were finally adjusted by stepwise regression.
Effects of Hydrolysed Poultry Byproduct Meal on Metabolic, Inflammatory and Oxidative Parameters in Cats.

Hydrolysed proteins are of interest owing to their potential effects on metabolic and physiological responses, low allergenicity and high digestibility. This study aimed to evaluate the use of hydrolysed poultry byproduct meal (HPM) as a replacement for conventional poultry byproduct meal (PBM) as a protein source and to study its effects on serum cytokines, angiotensin-converting enzyme (ACE) activity, serum antioxidant parameters, blood pressure, and urinary parameters in cats. The replacement of PBM with HPM was evaluated using five formulations with similar chemical compositions: control (PBM as the sole protein source) and the inclusion of 5%, 10%, 20%, and 30% HPM (on an as-fed basis).

This study utilized deep learning to optimize antihypertensive peptides from whey protein hydrolysate. Using the Large Language Models (LLMs), we identified an optimal multienzyme combination (MC5) with an ACE inhibition rate of 89.08% at a concentration of 1 mg/mL, significantly higher than single-enzyme hydrolysis.
