Article Abstract

Objective: This study aims to evaluate local control and intermediate-term cosmetic outcome in patients with cancer of the nose treated with intensity-modulated radiotherapy (IMRT).

Methods: From June 2008 to September 2015, 36 consecutive patients presenting with nasal cavity, ala of the nose, or nasal vestibule tumors were treated at the Department of Radiation Oncology, University Hospital Zurich either postoperatively (n = 14; 3/14 with nasal ablation) or with definitive IMRT (n = 22). Of these 36 patients, 8 presented with recurrent disease after surgery only and 1/36 with N1 disease. Concurrent systemic therapy was administered in 18/36 patients (50%). Nasal follow-up (FU) imaging documentation of 13 patients with preserved organ and >6 months FU offers a pre/post IMRT FU comparison. In addition, these patients' subjective evaluation of cosmesis was assessed.

Results: Mean/median FU was 41/33 months (range 5-92 months). Salvage ablation with curative intent was undergone by 3 patients with local relapse after definitive (n = 2) and postoperative (n = 1) IMRT. The 3‑year local control, ultimate local control, and overall survival rates were 90, 97, and 90 %, respectively. Subjective and objective cosmetic outcome after IMRT is very satisfying so far.

Conclusion: IMRT for nasal tumors was found to be effective and well tolerated. Intermediate-term cosmetic results are good. Radical surgical procedures may be saved for curative salvage treatment.

Retinal ganglion cells (RGCs) are highly compartmentalized neurons whose long axons serve as the sole connection between the eye and the brain. In both injury and disease, RGC degeneration occurs in a similarly compartmentalized manner, with distinct molecular and cellular responses in the axonal and somatodendritic regions. The goal of this study was to establish a microfluidic-based platform to investigate RGC compartmentalization in both health and disease states.

Programmable self-assembly has recently enabled the creation of complex structures through precise control of the interparticle interactions and the particle geometries. Targeting ever more structurally complex, dynamic, and functional assemblies necessitates going beyond the design of the structure itself, to the measurement and control of the local flexibility of the intersubunit connections and its impact on the collective mechanics of the entire assembly. In this study, we demonstrate a method to infer the mechanical properties of multisubunit assemblies using cryogenic electron microscopy (cryo-EM) and RELION's multi-body refinement.

Importance: It is unclear whether the duration of amyloid-β (Aβ) pathology is associated with neurodegeneration and whether this depends on the presence of tau.

Objective: To examine the association of longitudinal atrophy with Aβ positron emission tomography (PET)-positivity (Aβ+) and the estimated duration of Aβ+ (Aβ+ duration), controlling for tau-positivity.

Design, Setting, And Participants: Data for this longitudinal cohort study were drawn from the Wisconsin Registry for Alzheimer Prevention and the Wisconsin Alzheimer Disease Research Center Clinical Core Study.

Cell death mechanisms play a fundamental role in mycobacterial pathogenesis. We critically reviewed 94 research manuscripts, 44 review articles, and 4 book chapters to analyze important discoveries, background literature, and potential shortcomings in the field. The focus of this review is the pathogen (Mtb) and other Mtb and complex microorganisms.

Purpose: Glioblastoma (GBM) remains one of the most aggressive primary brain tumors with poor survival outcomes and a lack of approved therapies. A promising novel approach for GBM is the application of photodynamic therapy (PDT), a localized, light-activated treatment using tumor-selective photosensitizers. This narrative review describes the mechanisms, delivery systems, photosensitizers, and available evidence regarding the potential of PDT as a novel therapeutic approach for GBM.
