Role of [18F]FDG-PET/CT in Evaluation of Tumor Response to Chemoradiation Therapy for Advanced Colorectal Cancer.

Objectives: The objective is to evaluate the efficacy of F-fluorodeoxyglucose positron emission tomography (F-FDG-PET) computed tomography (CT) in the evaluation of tumor response to preoperative/palliative chemoradiotherapy (CRT) for advanced colorectal cancer; including metastatic cancer at primary presentation and recurrent cancers with local and/or distant metastasis.

Materials And Methods: Fifty patients with advanced rectal cancer underwent two point imaging with 18 FDG PET-CT before and after 3 weeks of completion of preoperative/palliative CRT in between 2016 and 2022. Patients with locally recurrent cancer also underwent radical surgery.

Minimally invasive thymectomy for patients with thymoma: surgical, oncological and neurological outcomes.

Background: Traditionally, sternotomy has been the gold standard approach for the treatment of thymomas. However, interest in minimally invasive techniques such as video-assisted and robot-assisted thymectomy is gaining momentum. Concerns have been raised over the possibility of en-bloc resection using minimal access techniques due to limited working space and increased tumour manipulation leading to tumour breach and recurrence.

Dear Laparoscopic Surgeons: Caution with the Use of Glutaraldehyde!!!

Background: The occupational hazards of glutaraldehyde are well known; the possibility of harm to the patients has been highlighted in the form of isolated reports only.

Objective: To synthesize evidence for contact mucosal injury or injury due to intraperitoneal instillation of glutaraldehyde following its use during laparoendoscopy.

Materials And Methods: The current review is Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) compliant.

Energetics and Redox Kinetics of Pure Ferrocene-Terminated -Heterocyclic Carbene Self-Assembled Monolayers on Gold.

heterocyclic carbene (NHC) self-assembled monolayers (SAMs) on gold have received considerable attention, but little is known about the lateral interactions between neighboring NHC molecules, their stability when subjected to aggressive oxidizing/reducing conditions, and their interactions with solution ions, all of which are essential for their use in a wide range of applications. To address these deficiencies, we present a comprehensive investigation of two different ferrocene (Fc)-terminated NHC SAMs with different chain lengths and linking groups. Pure monolayers of Fc-terminated NHCs display only a single, symmetrical pair of redox peaks, implying the formation of a homogeneous SAM structure with uniformly distributed Fc/Fc redox centers.
