Overview of the Head and Neck Tumor Segmentation for Magnetic Resonance Guided Applications (HNTS-MRG) 2024 Challenge.

Magnetic resonance (MR)-guided radiation therapy (RT) is enhancing head and neck cancer (HNC) treatment through superior soft tissue contrast and longitudinal imaging capabilities. However, manual tumor segmentation remains a significant challenge, spurring interest in artificial intelligence (AI)-driven automation. To accelerate innovation in this field, we present the Head and Neck Tumor Segmentation for MR-Guided Applications (HNTS-MRG) 2024 Challenge, a satellite event of the 27th International Conference on Medical Image Computing and Computer Assisted Intervention.

Direct and indirect modulation of STAT3/CSE/HS axis in triple negative breast cancer by non-coding RNAs: MALAT-1 lncRNA, miR-486-5p and miR-30a-5p.

Recently, our research group reported an upregulated expression profile of cystathionine γ-lyase (CSE) and cystathionine β-synthase (CBS), key enzymes involved in hydrogen sulfide (HS) production, in triple-negative breast cancer (TNBC) patients. However, the regulatory mechanisms underlying such altered expression patterns are not yet fully understood. In this study, we focused on the role of the STAT3/CSE/HS axis and the potential involvement of non-coding RNAs (ncRNAs), including long and short ncRNAs, in modulating this pivotal pathway.

Pathological Extramural Venous Invasion in High-stage Urothelial Carcinoma of the Bladder has Shorter Locoregional Recurrence-free Survival.

Extramural venous invasion is an independent prognostic factor in colorectal cancers; the pathological identification of extramural venous invasion in bladder cancer remains unclear. By focusing on high-stage urothelial carcinoma of the bladder, we provide insights into the pathological identification of extramural venous invasion in this particular clinical context. Clinical and demographic details and pathological reports were extracted from electronic medical records.

Role of Hydrogen Sulfide in Oncological and Non-Oncological Disorders and Its Regulation by Non-Coding RNAs: A Comprehensive Review.

Recently, myriad studies have defined the versatile abilities of gasotransmitters and their synthesizing enzymes to play a "Maestro" role in orchestrating several oncological and non-oncological circuits and, thus, nominated them as possible therapeutic targets. Although a significant amount of work has been conducted on the role of nitric oxide (NO) and carbon monoxide (CO) and their inter-relationship in the field of oncology, research about hydrogen sulfide (HS) remains in its infancy. Recently, non-coding RNAs (ncRNAs) have been reported to play a dominating role in the regulation of the endogenous machinery system of HS in several pathological contexts.
