Microsphere-Composite Hydrogel for Recruiting Stem Cells and Promoting Osteogenic Differentiation.

By recruiting stem cells into scaffolds and differentiating them into osteoblasts, stem cells can be mobilized to directly repair bone defects, which avoids a series of disadvantages of exogenous stem cell implantation. In this study, a microsphere-composite hydrogel for the recruitment and osteogenic differentiation of stem cells was constructed. Methacrylic anhydride modified gelatin (GelMA) and heparin (HepMA), as well as nanohydroxyapatite (nHAP), were used to prepare microspheres followed by adsorbing platelet-derived growth factor BB (PDGF-BB) whose loading efficiency was 53.

Genetic evidence causally linking gastroesophageal reflux disease to cholecystitis: a two-sample mendelian randomization study.

Background: Gastroesophageal reflux disease (GERD) and cholecystitis share overlapping symptoms, including belching, acid reflux, and heartburn. Despite this, the causal relationship between these two conditions remains unclear. This study aimed to investigate the causal link between GERD and cholecystitis using a Mendelian randomization (MR) approach.

Histone deacetylase 6 controls cardiac fibrosis and remodelling through the modulation of TGF-β1/Smad2/3 signalling in post-infarction mice.

Histone deacetylase 6 (HDAC6) belongs to the class IIb group of the histone deacetylase family, which participates in remodelling of various tissues. Herein, we sought to examine the potential regulation of HDAC6 in cardiac remodelling post-infarction. Experimental myocardial infarction (MI) was created in HDAC6-deficient (HDAC6) mice and wild-type (HADC6) by left coronary artery ligation.

Synthesis of C-N bonds by nicotinamide-dependent oxidoreductase: an overview.

Compounds containing chiral C-N bonds play a vital role in the composition of biologically active natural products and small pharmaceutical molecules. Therefore, the development of efficient and convenient methods for synthesizing compounds containing chiral C-N bonds is a crucial area of research. Nicotinamide-dependent oxidoreductases (NDOs) emerge as promising biocatalysts for asymmetric synthesis of chiral C-N bonds due to their mild reaction conditions, exceptional stereoselectivity, high atom economy, and environmentally friendly nature.

Clinicopathological characteristics, prognostic factors, and outcomes of elderly patients with lymphoma-associated hemophagocytic lymphohistiocytosis: A multicenter analysis.

Background: Lymphoma is the most common secondary cause of hemophagocytic lymphohistiocytosis (HLH) in adults. Lymphoma-associated HLH (LA-HLH) in the elderly population is not rare, however, little has been reported regarding clinicopathological characteristics, prognostic factors, and outcomes of LA-HLH in the elderly population.

Methods: We retrospectively analyzed a multicenter cohort of elderly patients with LA-HLH.

Predictive and prognostic value of preoperative pan-immune-inflammation value in patients with locally advanced rectal cancer.

This study aimed to investigate the prognostic value of the pan-immune-inflammation value (PIV) in patients with locally advanced rectal cancer (LARC) who received neoadjuvant chemoradiotherapy (nCRT) followed by total mesorectal excision. We retrospectively collected and analyzed the clinicopathological data of 215 resected LARC patients. X-tile software was used to determine the optimal threshold value for PIV in predicting overall survival (OS).

Impact the impact of gut microbiota on gastric cancer via immune cells: a comprehensive Mendelian randomization study and mediation analysis.

Purpose: Recent observational studies have highlighted the role of altered gut microbiota (GM) in the activation of the host immune system and the resulting of gastric cancer (GC). However, the exact causal relationship and mechanisms of action are still not fully understood.

Materials And Methods: Genetic data from published genome-wide association studies (GWASs) were employed to determine the causal effects of 207 taxa and 205 bacterial pathways on GC via two-sample Mendelian randomization (MR) and two-step mediation MR analysis.

Cognitive status, psychological state and needs of caregivers for elderly patients with home-induced pressure injuries: a qualitative study.

Pressure injury stands as a global healthcare concern, primarily affecting elderly individuals. As the ageing of the global population shows no signs of slowing down, both society and the families of the affected individuals continue to bear the brunt of the consequences of pressure injuries. The majority of pressure injury cases are managed at home, and the occurrence and progression of pressure injuries in the elderly are closely associated with informal caregivers.

The Congruence and Interrelationship: A Dyadic Perspective on the Subjective Cognitive Impairment in the Patients with Colorectal Cancer and Their Spousal Caregivers.

Objectives: Patients with colorectal cancer (CRC) reported experiencing subjective cognitive impairment (SCI), and their spousal caregivers perceived the patients' SCI. This cross-sectional study assessed the congruence of SCI between the patients' self-reports and the spousal caregivers' perceptions and examined the factors affecting SCI from the dyadic perspective.

Methods: A total of 200 dyads of patients with CRC and their spousal caregivers were invited to complete the survey, which evaluated the SCI, dyadic coping (DC), quality of life, anxiety, and depression for the dyads.

Human umbilical cord mesenchymal stem cells-derived exosomes attenuate burn-induced acute lung injury via inhibiting ferroptosis.

Our previous study has shown that exosomes derived from human umbilical cord mesenchymal stem cells (hUCMSCs-exo) alleviated burn-induced acute lung injury (ALI). In this study, we explored a novel mechanism by which hUCMSCs-exo contributed to the inhibition of burn-induced ALI. The ALI rat model with severe burn was established for the in vivo experiments, and rats PMVECs were stimulated with the serum from burn-induced ALI rats for the in vitro experiments.

[Systemic Inflammatory Markers Can Improve Survival Prediction of Patients with Diffuse Large B-Cell Lymphoma: Model Development and Evaluation].

Objective: To establish a model to predict the overall survival (OS) rate of patients with diffuse large B-cell lymphoma (DLBCL) based on systemic inflammatory indicators, and study whether the new model combined with inflammatory related parameters is more effective than the conventional model using only clinical factors to predict the OS of patients with DLBCL.

Methods: The clinical data of 213 patients with DLBCL were analyzed retrospectively. Backward stepwise Cox regression analysis was used to screen independent prognostic factors related to OS, and a nomogram for predicting OS was constructed based on these factors.
