The Potential of Oncolytic Virotherapy in the Treatment of Head and Neck Cancer: A Comprehensive Review.

Head and neck cancer (HNC) represents a challenging oncological entity with significant morbidity and mortality rates. Despite advances in conventional therapies, including surgery, chemotherapy, and radiation therapy, the overall survival rates for advanced HNC remain suboptimal. In recent years, the emerging field of oncolytic virotherapy has gained attention as a promising therapeutic approach for various malignancies, including HNC.

Overall impact of tethering and of its symmetric and asymmetric subtypes on early and long-term outcome of transcatheter edge-to-edge repair of significant mitral valve regurgitation.

Background: Tethering is a common condition of the mitral valve apparatus in the presence of significant regurgitation. Its impact on outcomes of transcatheter edge-to-edge repair (TEER) remains poorly characterized.

Methods: We appraised the prevalence, features, procedural details, and outcomes of patients with or without mitral valve tethering in a prospective multicenter observational study.

Collagen Matrix Versus Subepithelial Connective Tissue for Recession Coverage: A Systematic Review.

Objective: To evaluate the outcome of collagen matrix (CMX) compared with subepithelial connective tissue graft (SCTG) in gingival recession coverage (RC) surgery.

Methods: Review protocol was registered in PROSPERO. The search was conducted on MEDLINE, Cochrane Library, and Scopus databases.

Projections between the globus pallidus externa and cortex span motor and non-motor regions.

The globus pallidus externa (GPe) is a heterogenous nucleus of the basal ganglia, with intricate connections to other basal ganglia nuclei, as well as direct connections to the cortex. The anatomic, molecular and electrophysiologic properties of cortex-projecting pallidocortical neurons are not well characterized. Here we show that pallidocortical neurons project to diverse motor and non-motor cortical regions, are organized topographically in the GPe, and segregate into two distinct electrophysiological and molecular phenotypes.
