Metabolic insights into how multifunctional microbial consortium enhances atrazine removal and phosphorus uptake at low temperature.

Agricultural soils in the black soil region of northeast China often face negative stress due to low temperatures, pesticide contamination, and inadequate nutrient supply. In this study, a new cold-tolerant strain of Peribacillus simplex C1 (C1) was selectively isolated from atrazine contaminated soil. The artificially constructed microbial consortium (CPD) [C1, phosphorus-solubilizing bacterium Enterobacter sp.

Bidirectional relationship between frailty and cognitive function among Chinese older adults.

Background: Frailty and cognitive function are two common aging-related conditions among older adults. This study examined the bidirectional relationship between frailty and cognitive function according to sex.

Methods: All older adults aged ≥65 years who participated in the 2008 and 2014 waves of the Chinese Longitudinal Healthy Longevity Survey were included in this study.

Nutrition literacy differs based on demographics among University students in Bengbu, China.

Background: Nutrition literacy (NL) encompasses the knowledge and skills that inform individuals' food choices. This cross-sectional study explored factors associated with NL among Chinese university students in Bengbu, China.

Methods: A cross-sectional survey was carried out.

Metagenomic study of carbon metabolism in black soil microbial communities under lead-lanthanum stress.

Pollution of soil environments with heavy metals (HMs) and rare earth elements (REEs) cannot be ignored. We aimed to determine the effects of lead combined with lanthanum (Pb-La) on microbial community structure, carbon metabolism, and differences in carbon source utilization in black soils using EcoPlates™ and a macrogenomic approach. We found that Pb and La contents and the microbial community structure together influence and shape the response of soil carbon metabolism to Pb-La.

A positive association between hunger in childhood and frailty in old age: Findings from the Chinese longitudinal healthy longevity survey.

Background: Childhood hunger not only directly affects the physical and mental health of children and adolescents but also has a long-term negative effect on later health outcomes. In this cross-sectional study, we used a nationally representative Chinese sample to examine the relationship between hunger in childhood and frailty in older adults.

Materials And Methods: The data were obtained from the 2018 Chinese Longitudinal Healthy Longevity Survey.

Lanthanum-modified polydopamine loaded Acinetobacter lwoffii DNS32 for phosphate and atrazine removal: Insights into co-adsorption and biodegradation mechanisms.

A novel biobased composite was developed for the removal of phosphate (P) and atrazine from agricultural wastewater. A composite with strong P affinity and good biocompatibility, synthesized from La and polydopamine (PDA), was immobilized onto an atrazine-degrading bacterium Acinetobacter lwoffii DNS32 (La/PDA/DNS32). Following Box-Behnken design optimization, the maximum removal rate of P (500 mg L) and atrazine (100 mg L) by La/PDA/DNS32 reached 28 % and 100 %, respectively.

Development and validation of a novel short-form nutrition literacy measurement tool for Chinese college students.

Objectives: To develop and validate a short-form nutrition literacy (NL) assessment tool for Chinese college students based on a 43-item NL measurement scale.

Methods: To develop and validate short-form NL scale, 1359 college students were surveyed, the data were analyzed using exploratory factor analysis, linear regression analysis, Item analysis, confirmatory factor analysis, and Pearson correlation.

Results: The 12-item short-form NL scale (NL-SF12) was developed using factor analysis and regression analysis, which accounted for 96.

Long-term tea consumption reduces the risk of frailty in older Chinese people: Result from a 6-year longitudinal study.

Background: Vast accumulative evidence suggests that the consumption of tea and its components have various potential health benefits. This study used a longitudinal study to examine the causality between tea consumption and frailty in older Chinese people.

Methods: This study employed the longitudinal data from 2008 to 2014 of the Chinese Longitudinal Healthy Longevity Survey (CLHLS), which were systematically collected through face-to-face interviews.

Age, sex, residence, and region-specific differences in prevalence and patterns of multimorbidity among older Chinese: evidence from Chinese Longitudinal Healthy Longevity Survey.

Background: Multimorbidity among older adults, which is associated with added functional decline and higher health care utilization and mortality, has become increasingly common with the dramatic acceleration of ageing in China. The purpose of this study was to reveal age, sex, residence, and region- specific prevalence and patterns of multimorbidity among older adults in China.

Methods: This study is based on the 2018 Chinese Longitudinal Health Longevity Survey (CLHLS), the most recent edition of this national survey, and involved analysis of 15,275 participants aged 65 years and older.

Role of raising domestic animals in decreasing the risk of dementia occurrence in Chinese older adults: Evidence of a 10-year prospective cohort study.

This study explored the causal relationship between raising domestic animals and the risk of dementia occurrence. A 10-year cohort study was carried out drawing the data from Chinese Longitudinal Health Longevity Survey (CLHLS) 2008-2018. The Cox regression model was applied to analyze the association between raising domestic animals and the risk of developing dementia.

Monobutyl phthalate can induce autophagy and metabolic disorders by activating the ire1a-xbp1 pathway in zebrafish liver.

Monobutyl phthalate (MBP) can exist in biological organisms for a long time because of its excellent fat solubility, and it has been found to have certain toxic effects. In this study, the acute effects of MBP on endoplasmic reticulum (ER) stress and metabolism in the zebrafish liver were studied. After continuous exposure to MBP (5 and 10 mg / L) for 96 h, ER damage and the appearance of apoptotic bodies and autophagosomes were found in liver.

Anthraquinone-2,6-disulfonate enhanced biodegradation of dibutyl phthalate: Reducing membrane damage and oxidative stress in bacterial degradation.

Plasticizer dibutyl phthalate (DBP) pollution has received more and more attention. In this study, a DBP degrading bacteria Enterobacter sp. DNB-S2 was found to suffer membrane damage and oxidative stress during DBP degradation.

Efficient removal of atrazine by iron-modified biochar loaded Acinetobacter lwoffii DNS32.

In order to efficiently remove commonly used herbicide atrazine in farmland, an iron-modified biochar (FeMBC) was fabricated via chemical co-precipitation of Fe onto corn stalks biochar. The composites of FeMBC and Acinetobacter lwoffii DNS32 (bFeMBC) effectively accelerated the degradation rate of atrazine (100 mg L) in inorganic salt culture solution. TEM，XRD，XPS and FTIR were used to study the basic properties of the Materials.
