Developmental Trajectories of Intrinsic Capacity Among Older Adults: Results from the China Longitudinal Study of Aging.

: Previous studies have shown that intrinsic capacity changes over time and can independently predict adverse outcomes such as mortality and care dependence in older adults. However, explorations of the heterogeneity in the developmental trajectories of intrinsic capacity are limited. This study aimed to identify potential intrinsic capacity trajectory groups and the factors impacting different trajectory groups among older adults.

Identification of crucial genes for polycystic ovary syndrome and atherosclerosis through comprehensive bioinformatics analysis and machine learning.

Objective: To identify potential biomarkers in patients with polycystic ovary syndrome (PCOS) and atherosclerosis, and to explore the common pathologic mechanisms between these two diseases in response to the increased risk of cardiovascular diseases in patients with PCOS.

Methods: PCOS and atherosclerosis data sets were downloaded from the GEO database, and their differentially expressed genes were identified. Weighted gene co-expression network analysis was used to obtain intersection genes, and then protein-protein interaction and functional enrichment analysis were performed.

A relative weight analysis of the Chinese version of WAB.

Purposes: Investigating the contribution of each component of the Western Aphasia Battery (WAB) to the aphasia quotient (AQ) helps better understand the mechanisms of change in the AQ. Previous studies on patients with English-speaking aphasia have shown that spontaneous speech contributes the most to the AQ. However, the same conclusion may not be applicable to Chinese-speaking patients with aphasia because of the differences between Chinese and English languages.

Chiral carbon quantum dots for optical power limiting application.

In this research, the introduction of chirality into carbon quantum dots (CQDs) successfully facilitated the formation of chiral carbon quantum dots (CCQDs). These CCQDs manifested excellent photophysical properties. Moreover, chirality was exploited as a key factor to modulate the optical power limiting (OPL) properties of the CQDs.

Comparing Phenotypes for Acute and Long-Term Response to Atrial Fibrillation Ablation Using Machine Learning.

Background: It is difficult to identify patients with atrial fibrillation (AF) most likely to respond to ablation. While any arrhythmia patient may recur after acutely successful ablation, AF is unusual in that patients may have long-term arrhythmia freedom despite a lack of acute success. We hypothesized that acute and chronic AF ablation outcomes may reflect distinct physiology and used machine learning of multimodal data to identify their phenotypes.

SLC29A1 and SLC29A2 are human nicotinamide cell membrane transporters.

Nicotinamide (NAM), a main precursor of NAD+, is essential for cellular fuel respiration, energy production, and other cellular processes. Transporters for other precursors of NAD+ such as nicotinic acid and nicotinamide mononucleotide (NMN) have been identified, but the cellular transporter of nicotinamide has not been elucidated. Here, we demonstrate that equilibrative nucleoside transporter 1 and 2 (ENT1 and 2, encoded by SLC29A1 and 2) drive cellular nicotinamide uptake and establish nicotinamide metabolism homeostasis.

Microfluidic chip systems for color-based antimicrobial susceptibility test a review.

Clinical bacteria pose a significant public health threat, underscoring the need for reliable and rapid diagnostic methods for early disease detection, which can facilitate patient recovery. Current diagnostic methods for rapid pathogen detection often take hours to days and require numerous reagents and lengthy protocols. Microfluidic chip system offers a promising solution for clinical microbiology detection by reducing detection time with minimal setup and providing a point-of-care solution for patients.

Hijacking the hyaluronan assisted iron endocytosis to promote the ferroptosis in anticancer photodynamic therapy.

Photodynamic therapy (PDT) eradicates tumor cells by the light-stimulated reactive oxygen species, which also induces lipid peroxidation (LPO) and subsequently ferroptosis, an iron-depended cell death. Ferroptosis has a tremendous therapeutic potential in cancer treatment, however, the ferroptosis efficiency is largely limited by the available iron in cells. Through hijacking the CD44-mediated iron endocytosis of hyaluronan (HA), here PDT with enhanced ferroptosis was realized by a HA@Ce6 nanogel self-assembled from HA, a photosensitizer Chlorin e6 (Ce6) and Fe as cross-linkers.

Complexes of vertebrate TMC1/2 and CIB2/3 proteins form hair-cell mechanotransduction cation channels.

Calcium and integrin-binding protein 2 (CIB2) and CIB3 bind to transmembrane channel-like 1 (TMC1) and TMC2, the pore-forming subunits of the inner-ear mechano-electrical transduction (MET) apparatus. These interactions have been proposed to be functionally relevant across mechanosensory organs and vertebrate species. Here, we show that both CIB2 and CIB3 can form heteromeric complexes with TMC1 and TMC2 and are integral for MET function in mouse cochlea and vestibular end organs as well as in zebrafish inner ear and lateral line.

Production of the adjective and possessive markers in Chinese post-stroke aphasia.

Research has shown that patients with post-stroke aphasia may encounter difficulties in producing inflectional morphemes. Interestingly, they also show distinct challenges with the inflectional morphemes of homophones, such as the plural marker and the possessive marker in English. However, previous studies have predominantly focused on morphemes in European languages.

Serum hemoglobin and albumin levels serve as prognostic predictors after adrenal metastasectomy.

Purpose: Adrenal metastasectomy is a common local treatment for adrenal metastases, with a lack of serum prognostic factors. Here, we identified the prognostic significance of preoperative hemoglobin and albumin levels in patients undergoing adrenal metastasectomy.

Materials And Methods: Data from 93 patients who underwent adrenal metastasectomy were assessed retrospectively.

Involvement of Melatonin, Oxidative Stress, and Inflammation in the Protective Mechanism of the Carotid Artery over the Torpor-Arousal Cycle of Ground Squirrels.

Hibernating mammals experience severe hemodynamic changes over the torpor-arousal cycle, with oxygen consumption reaching peaks during the early stage of torpor to re-enter arousal. Melatonin (MT) can improve mitochondrial function and reduce oxidative stress and inflammation. However, the regulatory mechanisms of MT action on the vascular protective function of hibernators are still unclear.

Effect of Dual-Modified Tapioca Starch/Chitosan/SiO Coating Loaded with Clove Essential Oil Nanoemulsion on Postharvest Quality of Green Grapes.

As consumer awareness regarding health and nutrition continues to increase, there is a growing demand for fresh, nutritious fruits such as green grapes. However, the short storage life and susceptibility of these fruits to spoilage lead to significant commercial losses. Currently, the plastic wrap method is commonly used to keep green grapes fresh, but this packaging effect is limited and not environmentally friendly.

Transdiagnostic features of inflammatory markers and executive function across psychiatric disorders.

Executive dysfunction and dysregulated inflammation are found in patients with different psychiatric disorders. However, whether there are different associations between inflammatory markers and executive performance in patients with different psychiatric diagnoses is unknown. Our study aims were (1) to compare peripheral cytokine expression and executive function in patients with bipolar disorder (BD), substance use disorder (SUD), and schizophrenia (SCZ), and in healthy controls (HC) and (2) to explore the potential association between inflammatory cytokines and executive function in different patient groups and HC.

Contributions of mirror-image hair cell orientation to mouse otolith organ and zebrafish neuromast function.

Otolith organs in the inner ear and neuromasts in the fish lateral-line harbor two populations of hair cells oriented to detect stimuli in opposing directions. The underlying mechanism is highly conserved: the transcription factor EMX2 is regionally expressed in just one hair cell population and acts through the receptor GPR156 to reverse cell orientation relative to the other population. In mouse and zebrafish, loss of Emx2 results in sensory organs that harbor only one hair cell orientation and are not innervated properly.

Lightweight TiVNb medium-entropy alloy with weak strength dependence on temperature.

Herein, a TiVNb medium-entropy alloy was prepared via vacuum arc melting. The alloy maintained a body-centred cubic (BCC)-dominant phase following an annealing treatment at 1300 °C for 12 h. Although its structure was coarsened due to grain growth during annealing, the alloy developed a few Ti-rich nanobands and showed an increase in dislocations, resulting in its hardness increasing from 241.

Neoadjuvant chemoradiotherapy versus neoadjuvant chemotherapy for initially unresectable locally advanced colon cancer: short-term outcomes of an open-label, single-centre, randomised, controlled, phase 3 trial.

Background: Neoadjuvant chemotherapy (NACT) is commonly used to downstage the tumor in locally advanced colon cancer (LACC) and improve the R0 resection rate. Neoadjuvant chemoradiotherapy (NACRT) is the standard treatment for locally advanced rectal and esophageal cancers, but its benefits in LACC remain poorly understood. This study aimed to compare the effects and safety of NACRT and NACT on R0 resection and survival rates in initially unresectable LACC.
