Electrocardiographic Characteristics and Ablation Outcomes Associated With Para-Hisian Ventricular Arrhythmias.

Background: Ventricular arrhythmias (VAs) near the His-bundle comprise 9% of unexplained VAs and present challenges for ablation caused by the risk of atrioventricular block.

Objectives: The authors studied the electrocardiographic (ECG) and electrophysiological characteristics of Para-Hisian (PH) VAs, comparing them with septal right ventricular outflow tract VAs.

Methods: From 210 patients with VAs between 2018 and 2024, 31 (14.

Patterns of Oral and Maxillofacial Lesions in Eastern Uttar Pradesh Region: A Retrospective Study.

Background: Oral and maxillofacial lesions (OMFL) consist of a various malignant and benign lesions of the oral cavity. The aim of this study was to report the details of OMFL that had been diagnosed histologically at Oral Pathology Unit of a Dental Institute of eastern UP region.

Materials And Methods: Oral cavity biopsied submitted to the Oral Pathology Unit during the period from 2016 to 2021 was evaluated.

Comparison of Procedural Outcomes of Lumenless Fixed-Helix Versus Stylet-Driven Extendable-Helix Lead Systems in Left Bundle Branch Pacing: COMPARE LBBP.

Background: Left bundle branch pacing (LBBP) has emerged as a safe and effective alternative to right ventricular pacing. Traditionally, LBBP is performed with lumenless lead (LLL); however, the use of stylet-driven lead (SDL) is on rise. We aimed to assess acute success and procedural outcomes of SDL versus LLL for LBBP.

Exploring the role of angiogenesis in fibrosis and malignant transformation in oral submucous fibrosis: a systematic review and meta-analysis.

Angiogenesis is a crucial molecular driver of fibrosis in various inflammatory lesions. Oral submucous fibrosis (OSMF) is a chronic inflammatory fibrotic disorder with malignant potential. The angiogenetic pathways in OSMF remain obscure due to limited research, necessitating an in-depth review.

Taming CO via Synergistic Triple Catalysis in Anti-Markovnikov Hydrocarboxylation of Alkenes.

The direct utilization of carbon dioxide as an ideal one-carbon source in value-added chemical synthesis has garnered significant attention from the standpoint of global sustainability. In this regard, the photo/electrochemical reduction of CO into useful fuels and chemical feedstocks could offer a great promise for the transition to a carbon-neutral economy. However, challenges in product selectivity continue to limit the practical application of these systems.
