Fermented pompano (Trachinotus ovatus) is a traditionally popular fermented seafood throughout Asia. Its distinctive flavor profile is primarily attributed to the microbial metabolic conversion of nutrients, which produces specific volatile compounds. Two-dimensional flavoromics of mature pompano revealed that various volatile flavor compounds accumulate throughout fermentation, with fruity (predominantly esters) and oleogustus (primarily ketones) being key flavor markers.

The effect of oat β-glucan (OG) on the structure, interfacial behavior and emulsion rheological properties of sea bass myofibrillar protein (MP) was investigated. Fourier transform infrared spectroscopy demonstrated that adding OG decreased the α-helix content in MP from 27% to 22% and increased the β-sheet content, suggesting that OG facilitated MP unfolding. When the OG content was 1.

Fermented golden pompano is a traditional food valued for its distinctive flavor profile, largely influenced by lipid oxidation. This study evaluated the role of local Bacillus subtilis SCSMX-2 strain in regulating lipid oxidation and improving the flavor profile of the fermented golden pompano. Untargeted metabolomics was used to identify 206 differential metabolites, predominantly lipids, amino acids, and peptides.

Introduction: Hypertension is a chronic cardiovascular disease, which can trigger some disease such as heart failure, loss of vision or kidney. There were various peptides derived from food that are recognized for their ability to inhibit ACE activity, potentially leading to a reduction in blood pressure levels . The primary objective of this research is to discover ACE inhibitory peptides from protein hydrolysates of eel bone collagen (EBCHs).

Currently, constructing a mouse model for cold environmental stimulation employs cold-heat plates and wearable cooling devices. These methods can partially fulfill the requirements for studying the responses and regulatory effects of mouse skin or neural circuits to cold stimulation. Numerous clinical studies have substantiated the correlation between exposure to low-temperature environments and the development of various diseases.

Background And Purpose: Affective disturbances and cognitive impairment are common sequelae of intracerebral hemorrhage (ICH), yet predictive models for these outcomes remain limited, especially for spontaneous supratentorial ICH with small hematomas (<30 mL). The aim of this study was to investigate predictors of affective disturbances and cognitive impairment following small spontaneous supratentorial intracerebral hemorrhage.

Methods: We retrospectively analyzed 1692 patients with spontaneous supratentorial ICH between January 2018 and December 2020 at the First Affiliated Hospital of Harbin Medical University.

Fermented golden pompano (Trachinotus ovatus) has a distinctive flavor, but the key flavor compounds and aroma profiles remains unclear. Thus, a molecular sensory science approach was used to investigate flavor and key aromatic compounds. The fermentation process enhanced the overall flavor, as evidenced by sensory evaluation and electronic nose (E-nose) analyses.

Air frying as a new roasting technology has potential for roasted fish production. In this study, the changes in volatile compounds (VCs) during air frying of tilapia were studied by quantitative gas chromatography-ion mobility spectrometry, followed by the identification of key VCs based on their odor activity value (OAV). There were 34 verified VCs, of which 16 VCs were identified as the key VCs with OAV ≥ 1.

Objectives: Our aim is to evaluate the impact of surface ultraviolet radiation intensity on hospital admissions for stroke and to compare the correlation and differences among different subtypes of strokes.

Materials And Methods: We collected daily data on surface ultraviolet radiation intensity, temperature, air pollution, and hospital admissions for stroke in Harbin from 2015 to 2022. Using a distributed lag non-linear model, we determined the correlation between daily surface ultraviolet radiation intensity and the stroke admission rate.

Umami peptides originating from fermented sea bass impart a distinctive flavor to food. Nevertheless, large-scale and rapid screening for umami peptides using conventional techniques is challenging because of problems such as prolonged duration and complicated operation. Therefore, we aimed to screen fermented sea bass using peptidomics and machine learning approaches.

The aversion to cold is a fundamental motivated behavior that contributes to the body temperature homeostasis. However, the involvement of the lateral habenula (LHb) as a regulatory hub for negative emotions in this physiological process remains uninvestigated. In this study, we demonstrate an elevation in the population activity of LHb neurons following exposure to cold stimuli.

A facile and efficient method was reported for Cu-catalyzed selective α-alkylation processes of amino acids/peptides and α-bromo esters/ketones through a radical-radical coupling pathway. The reaction displays an excellent functional group tolerance and broad substrate scope, allowing access to desired products in moderate to excellent yields. Notably, this method is distinguished by site-specificity and exhibits total selectivity for aryl glycine motifs over other amino acid units.

There is increasing interest in understanding exercise as a potential treatment for cancer-related fatigue (CRF); however, rarely research has been conducted on more aggressive cancers with short survival, such as liver cancer. The purpose of this study was to provide educational ideas for insufficient exercise and provide clues for the design of effective and safe exercise intervention programs with high compliance in patients of advanced liver cancer in the future. Participants were recruited from a tertiary cancer hospital using convenience sampling.
