251 Dacryocystorhinostomy (DCR) for the treatment of nasolacrimal duct obstruction (NLDO) has been practiced for over a century. First described by Addeo Toti in 1904,[1] primary external DCR has traditionally been considered the gold standard technique demonstrating success rates that approach 98% in patients with primary acquired NLDO.[2,3] Caldwell first described the endonasal (non‐endoscop...

The cuticle covering every plant aerial organ is largely made of cutin that consists of fatty acids, glycerol, and aromatic monomers. Despite the huge importance of the cuticle to plant development and fitness, our knowledge regarding the assembly of the cutin polymer and its integration in the complete cuticle structure is limited. Cutin composition implies the action of acyltransferase-type e...

PURPOSE Dacryocystorhinostomy (DCR) is widely accepted as the procedure of choice for surgical correction of lacrimal drainage system obstruction distal to common canaliculus in adulthood. The success rate of DCR has been reported to be from 63% to 99%. DCR failure has been attributed to membranous occlusion of the rhinostomy site caused by soft tissue scarring. More recently, use of mitomycin ...

This work is a preliminary examination of mechanistic issues on the comparative corrosion performance of regular epoxy-coated rebar (ECR) and dual polymer-zinc coated reinforcement (DCR) in simulated concrete pore solution with and without chloride ions, at polarizations from +100 mV to -1000 mV in the saturated calomel electrode (SCE) scale and exposure periods of 1 month or longer. Both mater...

BACKGROUND Nasolacrimal duct obstruction is a common problem which can be corrected by dacryocystorhinostomy (DCR). The gold standard treatment for this is DCR operation through an external approach. Development of endoscopic sinus surgery and endoscopic DCR performed through intranasal route is a major recent development in this field. OBJECTIVES The aim of this study is to find out the succ...

INTRODUCTION External dacryocystorhinostomy (DCR) has been the gold standard for treatment of epiphora. Currently several endoscopic DCR techniques are described. We evaluated results of endonasal DCR in our institution. METHODS A retrospective chart review of a consecutive series of DCR procedures. Patients were subjected to a questionnaire a minimum of 6 months postoperatively to assess lon...

PURPOSE We evaluated the tolerability and efficacy of endoscopic dacryocystorhinostomy (Endo-DCR) in patients treated in the leaning position and under local anesthesia with minimal sedation (LAS). STUDY DESIGN Questionnaire to determine subjective success of Endo-DCR. METHODS From May 2013 to August 2014, a total of 95 eyes with epiphora presented to the Myoung Eye Plastic Surgery Clinic i...

We give a general technique for safe distribution of a declarative (global) process as a network of (local) synchronously communicating declarative processes. Both the global and local processes are given as Dynamic Condition Response (DCR) Graphs. DCR Graphs is a recently introduced declarative process model generalizing labelled prime event structures to a systems model able to finitely repre...

Poor instruction cache locality can degrade performance on modern architectures. For example, our simulation results show that eliminating all instruction cache misses improves performance by as much as 16% for a modestly sized instruction cache. In this paper, we show how to take advantage of dynamic code generation in a Java Virtual Machine (VM) to improve instruction locality at run-time. We...

This paper proposes a formal definition of the robustness property which, we believe, developers of future real-time (RT) local area network (LAN) protocols must aim to realize. A s a demonstration of the utility of this definition, the Carrier Sense Mult iple Access with Deterministic Collision Resolution (CSMA/DCR) protocol is then analyzed for its robustness and an extension of the CSMA/DCR ...
