INTRODUCTION Osteoradionecrosis (ORN) of the chest wall is a rare complication after whole-breast radiotherapy (RT). Herein, we report a case of ORN involving the underlying ribs following adjuvant whole-breast RT using standard fractionation and conduct a review of the literature. CASE REPORT A previously well 43-year-old female with right-sided, early-stage, node-negative breast cancer was ...
The role of Ca(2+) in insect olfactory transduction was studied in the moth Spodoptera littoralis. Single sensillum recordings were made to investigate in vivo the role of sensillar Ca(2+) on the electrophysiological properties of sex pheromone responsive olfactory receptor neurons (ORNs). Lowering the sensillar Ca(2+) concentration to 2 x 10(-8) M increased ORN spontaneous firing activity and ...
BACKGROUND The objective of the study is to compare complication rates of laparoscopic nephrectomy and open nephrectomy using a standardized classification method. METHODS We retrospectively included 843 patients from March 2006 to November 2012, of whom 88 had laparoscopic radical nephrectomy (LRN), 526 had open radical nephrectomy (ORN), 42 had laparoscopic partial nephrectomy (LPN), and 18...
TLRs 7 and 8 are pattern recognition receptors controlling antiviral host defense or autoimmune diseases. Apart from foreign and host RNA, synthetic RNA oligoribonucleotides (ORN) or small molecules of the imidazoquinoline family activate TLR7 and 8 and are being developed as therapeutic agonists. The structure-function relationships for RNA ORN and imidazoquinoline sensing and consequent downs...
To increase detection of a complex chemical environment, vertebrates and insects express an extraordinary number of distinct olfactory receptor neuron (ORN) classes, each functionally specialized to detect a set of odorants. This is achieved as the olfactory system develops and each of these ORN classes makes developmental decisions defining the olfactory receptor genes they will express and th...
BACKGROUND The aim of this study is to summarize and quantify the current evidence on the therapeutic efficacy of laparoscopic radical nephrectomy (LRN) compared with open radical nephrectomy (ORN) in patients with renal cell carcinoma (RCC) in a meta-analysis. METHODS Data were collected by searching Pubmed, Embase, Web of Science, and ScienceDirect for reports published up to September 26, ...
The dynamics of sensory input to the nervous system play a critical role in shaping higher-level processing. In the olfactory system, the dynamics of input from olfactory receptor neurons (ORNs) are poorly characterized and depend on multiple factors, including respiration-driven airflow through the nasal cavity, odorant sorption kinetics, receptor-ligand interactions between odorant and recept...
OBJECTIVE To review our experience with late Marx stage III osteoradionecrosis (ORN) of the mandible in patients who present with pathologic fracture. STUDY DESIGN Case series with chart review. SETTING Tertiary care center. SUBJECTS AND METHODS Thirty-seven patients were identified from June 1998 to August 2010 who underwent treatment of Marx grade III osteoradionecrosis with pathologic ...
