Transcriptional signature of CD56 NK cells predicts favourable prognosis in bladder cancer.

Human natural killer (NK) cells can be sub-divided into two functional subsets but the clinical significance of these CD56 and CD56 NK cells in anti-tumour immunity remains largely unexplored. We determined the relative abundances of gene signatures for CD56 and CD56 NK cells along with 3 stromal and 18 other immune cell types in the patient tumour transcriptomes from the cancer genome atlas bladder cancer dataset (TCGA-BLCA). Using this computational approach, CD56 NK cells were predicted to be the more abundant tumour-infiltrating NK subset which was also associated with improved patient prognosis.

A faunal inventory of methane seeps on the Pacific margin of Costa Rica.

The methane seeps on the Pacific margin of Costa Rica support extensive animal diversity and offer insights into deep-sea biogeography. During five expeditions between 2009 and 2019, we conducted intensive faunal sampling via 63 submersible dives to 11 localities at depths of 300-3600 m. Based on these expeditions and published literature, we compiled voucher specimens, images, and 274 newly published DNA sequences to present a taxonomic inventory of macrofaunal and megafaunal diversity with a focus on invertebrates.

IDH-mutant gliomas in children and adolescents - from biology to clinical trials.

Gliomas account for nearly 30% of all primary central nervous system (CNS) tumors in children and adolescents and young adults (AYA), contributing to significant morbidity and mortality. The updated molecular classification of gliomas defines molecularly diverse subtypes with a spectrum of tumors associated with age-distinct incidence. In adults, gliomas are characterized by the presence or absence of mutations in isocitrate dehydrogenase (), with mutated (mIDH) gliomas providing favorable outcomes and avenues for targeted therapy with the emergence of mIDH inhibitors.

Lingual Artery Identification for Ligation in Neck Dissection and Transoral Surgery for Oropharyngeal Tumors.

Objectives: Transoral robotic surgery (TORS) and transoral laser microsurgery (TOLM) plus neck dissection are viable alternatives to radiotherapy as a treatment modality in select cases of oropharyngeal squamous cell carcinoma. Many centers advocate for elective ligation of the feeding arteries at index neck dissection prior to TORS/TOLM to mitigate the risk of catastrophic perioperative hemorrhage. Although there are multiple cadaveric studies in the literature to identify the lingual artery at multiple points throughout its course, there are no studies on the intraoperative identification of the lingual artery for elective ligation prior to TORS/TOLM.
