The capacity of self-renewal and multipotent differentiation makes mesenchymal stem cells (MSC) one the most widely investigated cell lines in preclinical studies as cell-based therapies. However, low survival rate poor homing efficiency MSCs after transplantation hinder therapeutic application. Exosomes derived from have shown promising potential many diseases. heterogeneity may lead to differences function secreting exosomes. In this study, effects hUC-Exos hFP-Exos on DSS-induced colitis...

The association between sleep-related disorders and cardiovascular diseases (CVDs) remains controversial lacks epidemiological evidence in the general population. We investigated whether are related to CVDs a large, nationally representative, diverse sample of American adults.Data were collected from National Health Nutrition Examination Survey (NHANES) 2005-2008. Logistic regression was performed explore associations with prevalence total specific CVDs. Stratified subgroup analysis exclude...

Diabetic macular edema (DME) is the complication of diabetic retinopathy, leading cause vision loss among patients. Metformin main antidiabetic treatment. It preferable for its great anti-angiogenic and anti-inflammatory effects. Anti-vascular endothelial growth factor (VEGF) therapy treatment DME despite lack convincing results in some To assess whether combination metformin anti-VEGF drugs may decrease risk resistance We included patients with a central retinal thickness (CRT) ≥ 250 μm who...

Abstract Background Epidural labor analgesia is a safe and effective method of pain management during with the drawbacks delayed onset maternal distress epidural puncture. This study aimed to determine whether pretreatment intranasal low-dose dexmedetomidine effectively shortens reduces procedural pain. Methods In this prospective, randomized double-blind trial, nulliparous patients were randomly assigned either group or control group. The received 0.5 μg/kg intranasally, an equal volume...

Purpose: Retinal pigment epithelial (RPE) cells are highly specialized neural with several functions essential for vision. Progressive deterioration of RPE in elderly individuals can result visual impairment and, ultimately, blinding disease. While human embryonic stem cell-derived cell (hESC-RPE) growth conditions generally harsher than those lines, the subretinal transplantation hESC-RPE is being clinically explored as a strategy to recover damaged retina and improve The cell-adhesion...

Background In mainland China, patients with neovascular age-related macular degeneration (nAMD) have approximately an 40% prevalence of polypoidal choroidal vasculopathy (PCV). This disease leads to recurrent retinal pigment epithelium detachment (PED), extensive subretinal or vitreous hemorrhages, and severe vision loss. China has introduced various treatment modalities in the past years gained comprehensive experience treating PCV.Methods A total 14 specialists nationwide expertise PCV...

<title>Abstract</title> Objective: This study aimed to develop a prognostic signature for pancreatic cancer (PC) using immune checkpoint-related long non-coding RNAs (lncRNAs) and evaluate their clinical significance in PC patients. Methods: Transcriptome data information of patients were obtained from the Cancer Genome Atlas. Immune genes analyzed identify lncRNAs. Univariate Cox analysis, Lasso multivariate analysis performed select relevant lncRNAs construct signature. Independent...

Diabetic patients often experience visual defects before any retinal pathologies are detected. The molecular mechanism for the in early diabetes has not been elucidated. Our previous study reported that diabetic retinopathy (DR), rhodopsin levels were reduced due to impaired 11-&lt;i&gt;cis&lt;/i&gt;-retinal regeneration. Interphotoreceptor retinol-binding protein (IRBP) is a cycle and important generation. IRBP decreased vitreous retina of DR animal models. To determine role downregulation...

Abstract BackgroundAge-related diminished ovarian reserve (AR-DOR) reduced the quality of oocytes, resulting in decreased female fertility. Aging is tightly related to abnormal distribution and function mitochondria, while mitophagy a major process maintain normal quantity mitochondria cells, especially oocytes which containing large number meet demand energy production during oocyte maturation subsequent embryonic development.
