Different percentages of jujube yrup (0%, 3%, 6% and 9%) were incorporated into yak milk and fermented using the fermenting agent . The quality characteristics and antioxidant activity of the resulting yogurt were evaluated at days 0, 7, 14, 21 and 28. The results indicated that the pH and acidity of the yogurt were not significantly influenced by the varying additions of jujube syrup during storage ( > 0.

The structures and activities of enzymes are influenced by pH of the environment. Understanding and distinguishing the adaptation mechanisms of enzymes to extreme pH values is of great significance for elucidating the molecular mechanisms and promoting the industrial applications of enzymes. In this study, the ESM-2 protein language model was used to encode the secreted microbial proteins with the optimal performance above pH 9 and below pH 5, which yielded 47 725 high-pH protein sequences and 66 079 low-pH protein sequences, respectively.

Methods: Using the data of China Development and Nutrition Health Impact Cohort Survey from 2022 to 2023, 9981 residents aged 18 and above with complete three consecutive days with 24 h dietary recalls were selected as the research subjects. The intake status and food sources of dietary iron, zinc, selenium, and copper were analyzed and compared with the estimated average requirement(EAR) of iron, zinc, selenium and copper for Chinese residents.
Objective: To understand the intake status of nutrient supplements in 10 provinces(autonomous regions), so as to provide scientific evidence for guiding the rational use of nutrient supplements.
Methods: In this study, nutrient supplement is defined as raw materials including the categories in the "Health Food Raw Materials Catalog, Nutrient Supplements(2023 Edition)", and the product forms include health foods, OTC micronutrient supplements, and others. The scope of nutrient supplements in this study was defined.
Objective: To describe the prevalence and epidemic trends of several chronic multimorbidy among adult residents in 10 provinces(autonomous regions)of China over the past 14 years, and to analyze their multimorbidity patterns.
Methods: According to the fasting blood physiological and biochemical tests, physical measurements and questionnaires of 17 000 adult residents aged 18 years and above who were surveyed in 4 rounds of follow-up surveys in 2009, 2015, 2018 and 2023, the relevant indicators and disease history information of obesity, hypertension, diabetes mellitus, dyslipidemia, hyperuricemia, and various chronic diseases were obtained. Descriptive analysis was carried out to identify and compare several common combinations of multimorbidity in the population with 2 or more chronic disease conditions and the changing trends of 4 rounds of surveys.
