Experimental Myopia Results in Peripapillary Ganglion Cell and Astrocyte Reorganization with No Functional Implications During Early Development.

Myopic eye growth induces mechanical stretch, which can lead to structural and functional retinal alterations. Here, we investigated the effect of lens-induced myopic growth on the distribution of retinal ganglion cells (RGCs), glial fibrillary acidic protein (GFAP) expression and intensity, and peripapillary retinal nerve fiber layer (ppRNFL) thickness in common marmosets () induced with myopia continuously for six months, using immunohistochemistry and spectral-domain optical coherence tomography. We also explored the relationship between cellular structural parameters and the photopic negative response (PhNR) using full-field electroretinography.

Development and Validation of a Yoga-Based Intervention for Speech Dysfunction and Speech Difficulties Among Patients With Parkinson's Disease.

Introduction Parkinson's disease (PD) is primarily thought to be brought on by the death of dopaminergic neurons in the substantia nigra pars compacta of the basal ganglia. Communication difficulties are a common symptom of PD, affecting both motor speech and language systems. These challenges significantly impact the quality of life by reducing participation in communication, leading to social withdrawal, and increasing the risk of social isolation and stigma among individuals with PD.

Ready-to-use iPSC-derived microglia progenitors for the treatment of CNS disease in mouse models of neuropathic mucopolysaccharidoses.

Mucopolysaccharidoses are inherited metabolic disorders caused by the deficiency in lysosomal enzymes required to break down glycosaminoglycans. Accumulation of glycosaminoglycans leads to progressive, systemic degenerative disease. The central nervous system is particularly affected, resulting in developmental delays, neurological regression, and early mortality.
