Background: Stronger associations between modifiable risk factors and cognitive function have been found in younger than older adults. This age pattern may be subject to mortality selection and non-ignorable missingness caused by dropouts due to death, but this remains unclear.

Methods: Longitudinal data from 9,562 adults aged 50 and older from Waves 1-4 (2011-2018) of the China Health and Retirement Longitudinal Study were used.

Adaptive carbon ion radiotherapy for localized prostate cancer requires accurate evaluation of biological dose and dose-averaged linear energy transfer (LET) changes. This study developed a deep learning model to rapidly predict the modified micro-dosimetric kinetic model (mMKM)-based dose and LET distributions. Using data from fifty patients for training and testing, the model achieved gamma passing rates exceeding 96% compared to true mMKM-based dose and LET recalculated from local effect model I (LEM I) plans.

Article Synopsis
  • Mesenchymal stem cells (MSCs) show a specific tendency to move towards tumors, impacting cancer growth, treatment resistance, and immune response, prompting research into MSC-related biomarkers for better predicting bladder cancer outcomes.
  • This study used data from TCGA and GSE31684 to identify genes linked to MSCs and created a risk assessment model through advanced statistical analysis techniques.
  • The final prognostic model highlighted five key genes and classified bladder cancer patients into risk categories, revealing that high MSC-risk patients faced worse outcomes and lower responsiveness to immunotherapy and specific chemotherapy drugs compared to low MSC-risk patients.

This study presents a highly efficient method for 4-aminoquinoline derivative preparation under transition metal-free conditions. The process involves an aerobic oxidative dehydrative coupling of 2,3-dihydroquinolin-4(1)-ones with various amines, including ammonia, resulting in high yields of the desired products. The method is also applicable to substituted 4-aminoquinoline derivative construction through a cyclization/dehydrative coupling cascade process starting from 2'-amino chalcones.

Earlier start of the growing season (SGS) and delayed end of the growing season (EGS) affect plant carbon uptake. However, the effects of phenological changes on carbon allocation to different plant organs remain unclear. Here, we examined the effects and potential mechanisms of phenological changes on carbon allocation to different organs over the northern hemisphere (> 30° N).

Introduction: Single-injection pericapsular nerve group (PENG) block with ropivacaine provides clear analgesic effects in preoperative pain management for hip fractures. However, it suffers from insufficient duration, failing to meet the needs of most patients. This single-center, randomized controlled, observer-blinded trial utilizes a novel combination of liposomal bupivacaine (LB) single-injection PENG block to examine its efficacy, duration, and safety in preoperative analgesia for hip fractures, aiming to develop a new preoperative analgesic protocol.

The rising tide of bacterial drug resistance has sparked renewed interest in bacteriophages, the natural predators of bacteria. Our study highlights IME-EFm1, a Caudoviricetes bacteriophage specifically targeting Enterococcus faecium. Through our investigations, we identified that the gene IME-EFm1-ORF24 encodes an amidase, referred to as gp24, with promising lytic capabilities.

Dyskalemia are associated with an increased risk of mortality in patients undergoing maintenance hemodialysis (MHD). However, studies evaluating the impact of serum potassium variability on mortality in MHD patients are scarce. To investigate serum potassium variability and its association with prognosis in MHD patients, we conducted a retrospective study on maintenance hemodialysis patients from three campus of Renji Hospital between June 2018 and December 2022.

To analyze the value of the WT1 mRNA expression level in the diagnosis and prognostic evaluation of myelodysplastic syndrome (MDS) . A total of 403 patients with MDS, suspected MDS, and acute myeloid leukemia secondary to MDS (AML-MDS) from eight clinical trial centers in China were included in this multicenter, prospective study. Nucleic acid was extracted from the peripheral blood (PB) and bone marrow (BM) samples and WT1 mRNA expression was measured using the WT1 mRNA assay kit.

Reactive oxygen species (ROS)-responsive ion channels regulate the ion flow across the membranes in response to alterations in the cellular redox state, playing a crucial role in cellular adaptation to oxidative stress. Despite their significance, replicating ROS-responsive functionality in artificial ion channels remains elusive. In this study, we introduce a novel class of artificial H/Cl ion channels activatable by elevated ROS levels in cancer cells.

Article Synopsis
  • Acne vulgaris affects many young people globally, linked with increased levels of C acnes; concerns about antibiotic resistance push for nonpharmacological treatments like microneedling and postbiotics.
  • The study evaluated the effectiveness of a postbiotic formulation alongside microneedling in treating mild-to-moderate facial acne in 20 Chinese patients, focusing on symptom improvement and safety.
  • Results indicated significant improvements in acne severity and skin appearance, with high patient satisfaction and no major adverse reactions, suggesting this combination may be a promising alternative for managing acne.

Background: Musculoskeletal complications are one of the most common reasons for a patient with a spinal cord injury (SCI) to be rehospitalized. Bone loss due to immobilization and changes in metabolic processes because of the SCI lead to an increased risk of fractures.

Objective: To evaluate the prevalence and demographic characteristics of people living with an SCI who had a secondary fracture.

The signalling effects of microbial biofilms and extracellular polysaccharides (EPS) determine the stability of microbial communities. As messenger molecules, extracellular vesicles (EVs) mediate the interactions of microbial populations by carrying cargo. Therefore, this study took biofilm and EPS as screening factors, preliminarily explored the basic characteristics of strains with strong biofilm formation ability and high EPS production.

Background: The alpine wetlands in western Sichuan are distributed along the eastern section of the Qinghai-Tibet Plateau (QTP), where the ecological environment is fragile and highly sensitive to global climate change. These wetlands are already experiencing severe ecological and environmental issues, such as drought, retrogressive succession, and desertification. However, due to the limitations of computational models, previous studies have been unable to adequately understand the spatiotemporal change trends of these alpine wetlands.

  • * A study found that 24-hour systolic BPV showed a positive correlation with unilateral degrees of renal artery stenosis, suggesting that as stenosis increases, BPV also rises.
  • * However, no significant relationship was observed between BPV and bilateral renal artery stenosis, highlighting the need for further research on BPV and its implications in ARAS patients.

Shenhua Tablet (SHT), a Chinese herbal medicine comprising seven crude drugs, is utilized in the treatment of immunoglobulin A nephropathy (IgAN). However, due to its complex composition, the chemical constituents of SHT in vitro are still incompletely known, which has restricted the comprehensive development and utilization of SHT in clinical practice. In the present study based on ultra-high performance liquid chromatography-quadrupole-orbitrap-linear ion trap mass spectrometry (UHPLC-Q-Orbitrap-LTQ-MS) in data dependent acquisition mode, combining the accurate mass and structural information, the profiling and characterization of chemical constituents in SHT were carried out.

Sjögren's disease (SjD) is a chronic autoimmune disease, in which the immune system targets exocrine glands and leads to dryness symptoms. There is an increasing need to develop novel therapeutic approach as the treatment plan has not been changed in the past decade. However, findings in mouse model may not be directly applied in patients, given the substantial differences of immune system between human and mice.
