ETS1 Expression in Diabetic Foot Ulcers: Implications for Fibroblast Phenotype and Wound Healing Through the PP2A/YAP Pathway.

Objective: Diabetic foot ulcers (DFUs) are a serious complication of diabetes, characterized by impaired wound healing and high morbidity and mortality risks. While ETS1 is known to influence fibroblast pathological remodeling, its specific role in DFU and fibroblast wound healing remains unclear.

Methods: Skin tissue samples from DFU patients were categorized by Wagner grades to analyze ETS1 expression.

Corynebacterium parakroppenstedtii secretes a novel glycolipid to promote the development of granulomatous lobular mastitis.

Granulomatous lobular mastitis (GLM) is a chronic idiopathic granulomatous mastitis of the mammary gland characterized by significant pain and a high propensity for recurrence, the incidence rate has gradually increased, and has become a serious breast disease that should not be ignored. GLM is highly suspected relative to microbial infections, especially those of Corynebacterium species; however, the mechanisms involved are unclear, and prevention and treatment are difficult. In this study, we demonstrated the pathogenicity of Corynebacterium parakroppenstedtii in GLM using Koch's postulates.

Lymph node metastasis in cancer: Clearing the clouds to see the dawn.

Lymph node metastasis (LNM) is often regarded as an indicator of poor prognosis in various cancers. Despite over three centuries of exploration since its discovery, the molecular mechanisms underlying LNM remain inconclusive. This review summarizes the molecular mechanisms of LNM, using the "PUMP+" principle for clarification.

Aculeaquamides B and C, two new paraherquamides from the co-culture of Aspergillus aculeatinus WHUF0198 and Penicillium sp. DM27.

Two new paraherquamides (PHQs) namely aculeaquamides B and C (1 and 2), along with four known PHQs (3-6), were isolated from the co-culture of marine fungus Aspergillus aculeatinus WHUF0198 and mangrove-associated fungus Penicillium sp. DM27. Compound 1 represents the first PHQ derivative featuring an uncommon 7/6/5/5/6/5 hexacyclic system.

Introduction: Center-based rehabilitation is limited by COVID-19 infectivity and social distancing policy. We hypothesized that discharged patients benefit from 8-week home-based tele-rehabilitation (tele-PR) using mobile phones and low-cost instruments.

Methods: The TERCOV (Tele-rehabilitation in COVID-19 survivors) is an investigator-initiated, prospective, multi-center, real-world study.

Bone Destruction-Chemotactic Osteoprogenitor Cells Deliver Liposome Nanomedicines for the Treatment of Osteosarcoma and Osteoporosis.

Therapeutic efficacy of skeletal diseases is usually limited by unfavorable drug delivery due to incapable bone targeting and low bone affinity of conventional drug carriers, as well as relatively reduced vascularization and dense structure of bone tissues. Due to CXC chemokine receptor 4 (CXCR4)/CXC chemokine ligand 12 (CXCL12) signal axis-guided recruitment, osteoprogenitor cells (OPCs) can actively migrate to bone disease nidus. Here, drugs-loaded nanoliposomes are prepared and decorated onto OPCs by biotin-streptavidin linkage for precise bone disease targeting and effective drug delivery.

SET facilitates immune escape of microsatellite stability colorectal cancer by inhibiting c-Myc degradation.

Microsatellite stability (MSS) colorectal cancer (CRC) exhibits a low mutation load and poor immunogenicity, contributing to immune escape of tumor cells and less benefit from immune checkpoint blockade (ICB) treatment. The mechanisms underlying immunotherapeutic resistance in MSS CRC remain to be elucidated. Here, we identified that nuclear proto-oncogene SET is significantly higher expressed in MSS CRC compared to microsatellite instability (MSI) CRC and facilitates immune escape of MSS CRC.

Multi-omics insights into the microbiota-gut-brain axis and cognitive improvement post-bariatric surgery.

Background: Although numerous studies have shown that bariatric surgery results in sustained weight loss and modifications in gut microbiota composition and cognitive function, the exact underlying mechanisms are unclear. This study aimed to investigate the effects of bariatric surgery on cognitive function through the microbiota-gut-brain axis (MGBA).

Methods: Demographic data, serum samples, fecal samples, cognitive assessment scales, and resting-state functional connectivity magnetic resonance imaging (rs-fMRI) scans were obtained from 39 obese patients before and after (6 months) laparoscopic sleeve gastrectomy (LSG).

Association between neutrophil-to-lymphocyte ratio and short-term all-cause mortality in patients with cerebrovascular disease admitted to the intensive care unit-a study based on the MIMIC-IV database.

Background: Inflammation plays a crucial role in cerebrovascular disease (CVD) progression. Neutrophil-to-lymphocyte ratio (NLR) is an important inflammatory marker, though its diagnostic role in CVD is still under investigation. This study evaluates the relationship between NLR and short-term all-cause mortality in patients with CVD admitted to the intensive care unit (ICU).

Self-Adaptive Activation of DNAzyme Nanoassembly for Synergistically Combined Gene Therapy.

DNAzyme represents a promising gene silencing toolbox yet is obstructed by the poor substrate accessibility in specific cells. Herein, a compact DNA nanoassembly, incorporating multimeric therapeutic DNAzyme, was prepared for selective delivery of gene-silencing DNAzyme with requisite cofactors and auxiliary chemo-drugs. By virtue of the sequence-conservative duplex-specific nuclease, the endogenous miRNA catalyzes the successive and site-specific cleavage of DNA nanoassembly substrate (nominated as the localized RNA walking machine) and thus ensures the liberation/activation of therapeutic agents with high accuracy and efficacy.

Elevated circulating LncRNA NORAD fosters endothelial cell growth and averts ferroptosis by modulating the miR-106a/CCND1 axis in CAD patients.

Atherosclerosis is a leading cause of cardiovascular diseases, characterized by endothelial dysfunction and lipid accumulation. Long non-coding RNAs (lncRNAs) are emerging as key regulators of endothelial cell behavior. This study aimed to investigate the role of lncRNA NORAD in endothelial cell proliferation and as a potential therapeutic target for atherosclerosis.

The role of nicotinamide riboside in the preservation of retinal ganglion cells using an in vitro glutamate-induced excitotoxicity model.

Delaying or preventing the loss of retinal ganglion cells (RGCs) in glaucoma is needed for vision preservation. Glutamate-mediated neurotoxicity arises from the excessive stimulation of N-methyl-D-aspartate membrane receptors by glutamate. This overstimulation, occurring specifically in RGCs, triggers a progressive deterioration of the optic nerve that ultimately leads to the vision loss in glaucoma.

Clinical Effectiveness of a 3-Step Versus a 6-Step Hand Hygiene Technique: A Randomized Controlled Cross-over Study.

Background: The aim of this study is to assess the clinical effectiveness of the 3-step hand hygiene (HH) technique (3-HT) compared with the 6-step HH technique (6-HT; World Health Organization 6-step technique) using an alcohol-based hand rub.

Methods: A randomized controlled crossover trial was conducted from November to December 2023 in 10 wards of a tertiary A-level hospital according to CONSORT guidelines. The 240 healthcare workers (HCWs) were randomly divided into the 3-HT intervention group or the 6-HT control group.

Development and Validation of a Comprehensive Prognostic and Depression Risk Index for Gastric Adenocarcinoma.

Depressive disorder contributes to the initiation and prognosis of patients with cancer, but the interaction between cancer and depressive disorder remains unclear. We generated a gastric adenocarcinoma patient-derived xenograft mice model, treated with chronic unpredictable mild stimulation. Based on the RNA-sequence from the mouse model, patient data from TCGA, and MDD-related (major depressive disorder) genes from the GEO database, 56 hub genes were identified by the intersection of differential expression genes from the three datasets.

Dual-responsive renal injury cells targeting nanoparticles for vitamin E delivery to treat ischemia reperfusion-induced acute kidney injury.

Ischemia/reperfusion (I/R) is an important inducer of acute kidney injury (AKI), and triggers the generation of reactive oxygen species (ROS) and the expression of matrix metalloproteinase 2 (MMP2), exacerbating kidney damage. Given the immense potential of vitamin E (VitE) as a natural fat-soluble antioxidant in kidney protection, we designed the nanoparticles (NPs) that could dual respond to ROS and MMP2, aiming to accurately deliver VitE to renal injury cells. The NPs utilized Gel-SH as a sensitive receptor for MMP2 and diselenide as a sensitive receptor for ROS, while PEG modification enhanced biocompatibility and prevented phagocytosis mediated by the mononuclear phagocyte system.
