Malignant astrocytomas are aggressive primary brain tumors characterized by extensive hypoxia-induced, mitochondria-dependent changes such as altered respiration, increased chymotrypsin-like (CT-L) proteasome activity, decreased apoptosis, drug resistance, stemness, and increased invasiveness. Mitochondrial Lon Peptidase 1 (LonP1) overexpression and increased CT-L proteasome activity are biomarkers of an aggressive high-grade phenotype and found to be associated with recurrence and poor patient survival. In preclinical models, small molecule agents targeting either LonP1 or the proteasome CT-L activity have anti-astrocytoma activity.

This study investigated the awareness, adoption, and impact of the new classification on adult glioma management among healthcare professionals in Africo-Asian region. Through a structured survey questionnaire distributed across these regions, assessment of the level of awareness, diagnostic changes, challenges faced, and future perspectives among respondents was done.

The illness often manifests late in life, with diverse neurological and psychiatric symptoms, suggesting involvement of different brain regions. Prominent neuronal loss and atrophy of the cerebellum have been noted earlier.

To identify and evaluate alternative procedures for the treatment of small-angle vertical strabismus in the elderly, we conducted a comprehensive literature search in PubMed and Google Scholar. Here, we identify and evaluate new surgical techniques that target small-angle vertical strabismus, including graded partial tenotomy, partial tendon recession, minitenotomy, and miniplication.
