Methods: This study included 3,726 participants from the Chinese Longitudinal Healthy Longevity Study (CLHLS).

Proteome remodeling upon disruption of virulence-associated CipC from .

The human fungal pathogen, , produces an array of virulence factors that regulate the production of a polysaccharide capsule and melanin, thermotolerance, and the release of extracellular enzymes. Here, we applied quantitative proteomics to investigate the role of CipC, a known virulence-associated protein, in the fungus.

Sarcopenia, Depressive Symptoms, and Fall Risk: Insights from a National Cohort Study in the Chinese Population.

Background: Previous investigations have indicated that both sarcopenia and depressive symptoms are linked to a heightened risk of falls. However, the potential synergistic effect of these conditions on fall risk remains unclear. This study aims to assess the combined influence of sarcopenia and depressive symptoms on the occurrence of falls in the Chinese population.

Association Between Cognitive Frailty and Depression: A Prospective Cohort Study of Adults Aged 45 Years and Older in China.

Background: The interplay between cognitive frailty and depression remains inadequately understood, with a paucity of evidence from prospective cohort studies. Our study aims to elucidate the relationship between cognitive frailty and the risk of incident depression.

Methods: Utilizing data from the China Health and Retirement Longitudinal Study (CHARLS) spanning 2011, 2013, and 2015, subjects were classified according to cognitive frailty criteria established by an international consensus panel.

Relationship between serum carotenoids and telomere length in overweight or obese individuals.

Background: Previous researches have demonstrated an association between carotenoids and elongated telomeres. Nonetheless, there is scant scientific evidence examining this relationship in individuals who are overweight or obese, a demographic more predisposed to accelerated aging. This study aims to elucidate the correlation between serum carotenoid concentrations and telomere length within this population group.

Integrative metabolomics - GC-IMS approach to assess metabolic and flavour substance shifts during fermentation of Yangjiang douchi.

Douchi is traditional Chinese condiment. In this study, electronic sense, GC-IMS and metabolomics were combined to analyse the changes in flavour profiles and metabolites of Yangjiang douchi at different fermentation stages. The results showed that umami was the primary taste characteristic of douchi.

Engineering organoids-on-chips for drug testing and evaluation.

Organoids-on-chips is an emerging innovative integration of stem cell-derived organoids with advanced organ-on-chip technology, providing a novel platform for the in vitro construction of biomimetic micro-physiological systems. The synergistic merger transcends the limitations of traditional drug screening and safety assessment methodologies, such as 2D cell cultures and animal models. In this review, we examine the prevailing challenges and prerequisites of preclinical models utilized for drug screening and safety evaluations.

Flowering in aged white tea: Recovering umami taste and amplifying of stale aroma.

Throughout the natural aging process from new to aged white tea, the flavor evolves into a 'stale flavor', despite the initial umami diminishes. The flowering process, inoculation of Eurotium cristatum to white tea, improves the flavor. The impact on sensory qualities and underlying chemical basis of flowering in aged white tea warrant investigation.

Increasing Endoglin Deletion in Endothelial Cells Exacerbates the Severity of Brain Arteriovenous Malformation in Mouse.

Endoglin () mutation causes type 1 hereditary hemorrhagic telangiectasia (HHT1). HHT1 patients have arteriovenous malformations (AVMs) in multiple organs, including the brain. In mice, deletion induced by R26RCreER or SM22αCre leads to AVM development in the brain and other organs.

Associations between modifiable risk factors and frailty progression among individuals with pre-frailty.

Background: In the context of the present global aging phenomenon, the senior population and pace of aging in China have emerged as prominent issues on the worldwide stage. Frailty, a complicated condition that is closely linked to the clinical syndrome of advancing age, poses a considerable health risk to older individuals. Frailty status was assessed by the frailty index (FI) ranging from 0 to 1, pre-frailty was defined as >0.

Golden-flower fungus (Eurotiwm Cristatum) presents fungal flower aroma as well as accelerates the aging of white tea (Shoumei).

Golden-flower fungus (Eurotiwm Cristatum, EC) is widely inoculated in dark tea to endow a typical fungal floral aroma. Recently, Golden Flower White Tea (GFWT), prepared by transplanting EC-mediated fermentation to white tea (Shoumei, SM) to reform the roughness and coarseness, has attracted much attention attributed to coordinated flavor. However, the bio-chemistry reactions between EC and SM, along with origination of composited aroma are still unclear.

Construction of power network security risk assessment model based on LSA-SVM algorithm in the background of smart grid.

Due to theintricate and interdependent nature of the smart grid, it has encountered an increasing number of security threats in recent years. Currently, conventional security measures such as firewalls, intrusion detection, and malicious detection technologies offer specific protection based on their unique perspectives. However, as the types and concealment of attacksincrease, these measures struggle to detect them promptly and respond accordingly.

Application of chiral stationary phases for the separation of vitamin A acetate isomers.

The separation of vitamin A acetate isomers is essential for quality assurance of e.g. nutrition supplements, cosmetics, and pharmaceutical ingredients.

Microfluidic strategies for biomimetic lung chip establishment and SARS-CoV2 study.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV2), characterized by its high fatality rate and contagious nature, has led to significant morbidity and mortality worldwide, significantly impacting both our daily lives and public health. The respiratory pathway serves as the primary route for SARS-CoV2 propagation within the human body, with the lung acting as the initial target organ. Simultaneously, the lung functions as a protective barrier, preventing the entry of viruses into the bloodstream through the alveolar-capillary barrier.

Neuron Navigator 1 (Nav1) regulates the response to cocaine in mice.

Genetic variation accounts for much of the risk for developing a substance use disorder, but the underlying genetic factors and their genetic effector mechanisms are mostly unknown. Inbred mouse strains exhibit substantial and heritable differences in the extent of voluntary cocaine self-administration. Computational genetic analysis of cocaine self-administration data obtained from twenty-one inbred strains identified Nav1, a member of the neuron navigator family that regulates dendrite formation and axonal guidance, as a candidate gene.

Anthocyanin metabolism and its differential regulation in purple tea (Camellia sinensis).

Tea plants (Camellia sinensis) typically contain high-flavonoid phytochemicals like catechins. Recently, new tea cultivars with unique purple-colored leaves have gained attention. These purple tea cultivars are enriched with anthocyanin, which provides an interesting perspective for studying the metabolic flux of the flavonoid pathway.

Polysaccharides from Fu brick tea ameliorate obesity by modulating gut microbiota and gut microbiota-related short chain fatty acid and amino acid metabolism.

Fu brick tea (FBT) is a traditional tea manufactured by solid-state fermentation of tea leaves (Camellia sinensis). Although anti-obesity effects have been reported for FBT, the associated role of FBT polysaccharides (PSs) and the underlying mechanisms remain unknown. In this study, we found that FBTPSs inhibited obesity, hyperlipidemia, and inflammation; improved intestinal barrier function; and alleviated gut microbiota dysbiosis in high-fat diet-fed rats.
