Differences in brain volume and thickness in patients with pulmonary or spine tuberculosis (TB) compared to non-TB individuals: A cross-sectional retrospective study.

Introduction: There is evidence showing that central nervous system TB (CNS-TB) causes meningitis, pachymeningitis, tuberculomas, and granulomas. However, the impact of pulmonary or spine TB on brain morphology and thickness is yet to be documented. TB is associated with increased levels of inflammatory biomarkers in specific brain regions.

The emerging role of noncoding RNAs in the EGFR signaling pathway in lung cancer.

Noncoding ribonucleic acids (ncRNAs) have surfaced as essential orchestrators within the intricate system of neoplastic biology.
