Impact of Local Extent of Tumor on the Survival Outcomes for Surgically Treated Tongue Cancers.

Background: The current classification of tongue cancers does not discriminate stages based on factors of local spread.

Aim: Integrating factors of local spread that impact disease-specific survival (DSS) in a modified classification to improve prognostication compared with the current staging.

Method: This was a retrospective analysis of 399 previously untreated oral tongue squamous carcinomas operated between 2016 and 2018.

Basal forebrain innervation of the amygdala: an anatomical and computational exploration.

Theta oscillations of the mammalian amygdala are associated with processing, encoding and retrieval of aversive memories. In the hippocampus, the power of the network theta oscillation is modulated by basal forebrain (BF) GABAergic projections. Here, we combine anatomical and computational approaches to investigate if similar BF projections to the amygdaloid complex provide an analogous modulation of local network activity.

Design, Safety and Efficacy Evaluation of Gemcitabine-eluting Nanoyarn-integrated Heparinized Self Expanding Metallic Stents for Long-Term Management of Malignant Biliary Obstruction.

Malignant biliary obstruction presents a significant therapeutic challenge and has serious consequences including cholangitis and death. Clinically, biliary stenting using self-expanding metallic- stent(SEMS) relieves this obstruction. However, stent occlusion occurs with time due to tumor/epithelial in-growth and bacterial colonization.

Microwave-Assisted Synthesis of Heterocycles via Rhodium(III)-Catalyzed C-H Activation: Norbornadiene as an Acetylene Equivalent.

General procedures for the rhodium-catalyzed annulation of aryl/heteroaryl -pivaloyl hydroxamic acids and norbornadiene have been developed. Employing norbornadiene as an acetylene equivalent enables utilization of diverse heterocyclic substrates for this transformation which fail to react or undergo competitive Lossen rearrangement under previously reported conditions. Microwave heating significantly reduces reaction times compared to conventional protocols and allows a one-step process to be realized.
