Age-related macular degeneration (AMD) is a chronic multifactorial degenerative eye disease and one of the leading causes of irreversible blindness worldwide. Despite extensive research, there is no consensus on the predominant pathological mechanism leading to photoreceptor death. AMD is associated with molecular and cellular disruptions that ultimately result in photoreceptor degeneration.

Purpose: To assess the colocalization of ellipsoid zone (EZ) disruption with nonperfusion in choriocapillaris (CC), retinal superficial capillary plexus (SCP), and deep capillary plexus (DCP) in diabetic patients using en face optical coherence tomography (OCT) and OCT angiography (OCTA).
Methods: Macular OCT and OCTA scans (3 × 3 mm) of 41 patients with diabetic retinopathy were obtained using an RTVue XR Avanti instrument. After correcting the shadow artifacts, EZ integrity was assessed in the en face OCT slab using the Gaussian mixture model clustering method compared with the corresponding EZ en face OCT of 11 age-matched normal patients.

Diabetes exacerbates the occurrence and severity of periodontitis, the pathogenesis of diabetic periodontitis (DPD) is influenced by the delayed resolution of inflammation. Eldecalcitol (ED-71) has shown promise in preventing bone loss in DPD. We herein aimed to investigate the role of ED-71 in the inflammatory regression phase of DPD and elucidate the underlying mechanisms.

Background: Extracellular vesicles are easily accessible in various biofluids and allow the assessment of disease-related changes in the proteome. This has made them a promising target for biomarker studies, especially in the field of neurodegeneration where access to diseased tissue is very limited. Genetic variants in the LRRK2 gene have been linked to both familial and sporadic forms of Parkinson's disease.

Electronic address:
High sensitivity and specificity in microRNA detection are of great significance for early cancer screening. This study employed a pre-assembled bulb-shaped G-quadruplex signal unit (G4MB) as a novel and efficient label-free probe. The products amplified by the miRNA-155-targeted exponential amplification reaction (EXPAR) activated the trans-cleavage activity of CRISPR/Cas12a, disrupting the G4MB structure to achieve dual-channel fluorescence/colorimetric (FL/CM) inverse signal output.
