Mycoplasma pneumonia, caused by Mycoplasma bovis (Mycoplasmopsis bovis; M. bovis), is linked with severe inflammatory reactions in the lungs and can be challenging to treat with antibiotics. Biofilms play a significant role in bacterial persistence and contribute to the development of chronic lesions.

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).
A comprehensive evaluation of histopathology foundation models for ovarian cancer subtype classification.

Histopathology foundation models show great promise across many tasks, but analyses have been limited by arbitrary hyperparameters. We report the most rigorous single-task validation study to date, specifically in the context of ovarian carcinoma morphological subtyping. Attention-based multiple instance learning classifiers were compared using three ImageNet-pretrained encoders and fourteen foundation models, each trained with 1864 whole slide images and validated through hold-out testing and two external validations (the Transcanadian Study and OCEAN Challenge).

Usher syndrome is a rare autosomal recessive genetic disorder that primarily affects both vision and hearing, manifesting as sensorineural hearing loss and progressive vision loss caused by retinitis pigmentosa. The pathogenesis of retinal degeneration in Usher syndrome is still largely unknown. In this study, a novel Ush2a knockout mouse model was successfully constructed using CRISPR/Cas9 technology.

Methicillin-resistant Staphylococcus aureus (MRSA) is one of the leading causes of infection worldwide due to its antimicrobial resistance. Plant-derived essential oils (EOs) have undergone extensive observational and clinical research to explore their antimicrobial properties. The present study aimed to check mec A positive MRSA isolates using sequencing analysis, determination of chemical composition using gas chromatography-mass spectroscopy (GC-MS), antioxidant, and antimicrobial activity of Anethum graveolens and Piper betle EOs against the infectious agent MRSA.
