Sleep characteristics and intervertebral disc degeneration risk: an observational and Mendelian randomization study.

Objectives: Sleep disorders are considered a risk factor for aging and skeletal degeneration, but their impact on intervertebral disc degeneration (IDD) remains unclear. The aim of this study was to assess associations between sleep characteristics and IDD, and to identify potential causal relationships.

Methods: Exposure factors included six unhealthy sleep characteristics: insomnia, short sleep duration (< 7 h), long sleep duration (≥ 9 h), evening chronotype, daytime sleepiness, and snoring.

Clinical Features Evaluation of Myopic Fundus tessellation from OCTA and MfERG.

Purpose: To evaluate the differences in fundus tessellation among various severities using multifocal visual electrophysiology (MfERG) and optical coherence tomography angiography (OCTA) for clinical grading and treatment.

Methods: This study included 52 patients totaling 87 eyes. The Early Treatment Diabetic Retinopathy Study (ETDRS) grid division method was utilized to assess Grade of fundus tessellation.

p16 promoted progress of MCT induced pulmonary hypertension via maintaining redox balance and autophagy pathway.

Pulmonary arterial hypertension (PAH) is a disease characterized by increased pulmonary vascular resistance and elevated pulmonary arterial pressure. Currently, pathogenesis of PAH remains poorly understood, and therapeutic options are limited. In this study, we aimed to explore role of p16INK4A (p16) in the development of PAH using mouse model induced by monocrotaline (MCT).

Comparative evaluation of allograft particulate bone and cortical bone blocks combined with xenograft bone for labial bone defects in the aesthetic zone: a prospective cohort study.

Purpose: This study aimed to evaluate the osteogenic performance of allograft particulate bone and cortical bone blocks combined with xenograft under bovine pericardium membranes, for treating different degrees of labial bone defects in the aesthetic zone.

Materials And Methods: Twenty-four patients with bone defects were divided into two groups based on defect severity (Terheyden 1/4 and 2/4 groups). The Terheyden 1/4 group received granular bone grafts alone, while the Terheyden 2/4 group received cortical bone blocks combined with granular bone grafts.

Associations between domestic hard water exposure and incident psoriasis in adults: Insights from the UK Biobank cohort study.

Although exposure to hard water is associated with various inflammatory skin conditions, the specific relationship between hard water and psoriasis has not been clearly defined. We analyzed data from 486,414 participants in the UK Biobank cohort to explore the association between domestic hard water exposure and the incidence of psoriasis. Domestic water hardness, measured in calcium carbonate concentration, was obtained in 2005 from local water providers in Wales, Scotland, and England.
