Corneal nerve abnormalities in early-stage diabetic retinopathy evaluated by corneal confocal microscopy.

January 2025
Affiliated Hospital of Xuzhou Medical University, Xuzhou, Jiangsu, 221006, China.
Objective: This study aims to investigate the correlation between the development of diabetic retinopathy (DR) and the changes in corneal sub-basal nerve plexus (SNP) and corneal dendritic cells (DCs).
Methods: 58 patients with type 2 diabetes mellitus (T2DM) and 30 age- and sex-matched healthy participants underwent assessment of the corneal nerve. The DR group was divided into no diabetic retinopathy (NDR) and 29 eyes with mild to moderate non-proliferative diabetic retinopathy (NPDR).
The big, the small and the weird: A phylogenomic analysis of extant Priapulida.

Priapulida is a small phylum of 22 described species that are divided into two size classes (microscopic and macroscopic), distinguished by adult and larval morphology. Most priapulidans are rare or live in inaccessible habitats, and freshly collected material for molecular studies is difficult to obtain. With this study, we for the first time aim to resolve the phylogeny of extant Priapulida using transcriptomic, genomic, and morphological data.

Background: The intercondylar space is defined as the topographic area walled by the intercondylar notch (IN) and encasing the central ligaments of the knee joint. As the anterior cruciate ligament (ACL) is not only impinged against the roof but also against the lateral wall of the IN, information concerning changes to the IN during the progression of osteoarthritis could be potentially relevant in predicting the future risk for ACL-rupture and -degeneration and ensure preventive measures as early as possible. Therefore, the purpose of this study was to evaluate the influence of osteoarthritis on osseous notch morphology.

Electronic address:
Microplastic pollution has emerged as a significant environmental concern at the global level, potentially threatening biodiversity conservation and human wellbeing. As an important biological group with a wide global distribution, migratory shorebirds face considerable stress due to plastic and microplastic pollution. However, few studies have explored the ecotoxic impact of microplastic pollution on migratory shorebirds.

This study aimed to synthesize MgFeLnO (where, Ln = Yb, Pr, Gd, and Nd) ferrite nanoparticles via the sol-gel process and investigate their structural, morphological, and magnetic properties for potential hyperthermia applications. X-ray diffraction analysis (XRD) confirmed the cubic spinel structure for all samples. Transmission electron microscopy (TEM) images revealed nanometer-scale dimensions and nearly spherical morphology.
