PURPOSE The aim of this study is to present a surgical technique used to treat epiphora secondary to difficult cases of lacrimal pathway obstruction after fractures, previous surgery or anatomic abnormalities. METHODS From January 2001 to December 2002 we treated 27 patients with complicated lacrimal pathway obstruction secondary to fractures (10 cases), previous nasal surgery (4 cases), fail...

AIM To evaluate a new approach of recanalisation of nasolacrimal duct obstruction (RC-NLDO) in the treatment of the nasolacrimal duct obstruction (NLDO) and chronic dacryocystitis. METHODS 583 patients with 641 eyes suffering from NLDO and chronic dacryocystitis were enrolled in this study. The RC-NLDO was performed in 506 eyes, with 135 eyes undergoing external dacryocystorhinostomy (EX-DCR)...

Complete coverage of an unknown environment is a valuable skill for a variety of robot tasks such as oor cleaning and mine detection. Additionally, for a team of robots, the ability to cooperatively perform such a task can signi cantly improve their eÆciency. This paper presents a complete algorithm DCR (distributed coverage of rectilinear environments) which gives robots this ability. DCR is a...

Introduction Since the days of Hippocrates, many modifications have been proposed in endonasal dacrocystorhinostomy (DCR), with the use of new drugs and implants showing variable results. The objective of this study was to analyze whether the use of silicon tubing or mitomycin C administration has an added advantage over conventional endonasal DCR. Materials and Methods A randomized controlle...

MicroRNAs (miRNAs) have been implicated in cell-cycle regulation and in some cases shown to have a role in tissue growth control. Depletion of miRNAs was found to have an effect on tissue growth rates in the wing primordium of Drosophila, a highly proliferative epithelium. Dicer-1 (Dcr-1) is a double-stranded RNAseIII essential for miRNA biogenesis. Adult cells lacking dcr-1, or with reduced dc...

Vibrio renopiscarius DCR 1-4-2(T) (CECT 8603(T)) and DCR 1-4-12 (CECT 8604) were isolated from healthy gilthead sea bream (Sparus aurata) from Mediterranean fish farms (Castellón, Spain). Their draft genome sequences (30 and 44 contigs, respectively) have 4.3 Mbp and a G+C content of 45.2 mol% and contain almost 3,700 protein-encoding genes.

Electrical methods offer a potential geophysical approach to determining the sub-bottom distribution of gas hydrate in the deep marine environment. Gas hydrate is essentially nonconductive. Hence, sediments with pore spaces partially filled with hydrate or containing veins filled with hydrate are more resistive than surrounding sediments with pore spaces filled with seawater. To date, attempts ...

OBJECTIVES Military casualties with vascular injuries often present with severe acidosis and coagulopathy that can negatively influence limb salvage decisions. We previously reported the value of a damage control resuscitation (DCR) strategy that can correct physiologic shock during simultaneous vascular reconstruction. The effect of recombinant factor VIIa (rFVIIa) on the repair of injured ves...

BACKGROUND A number of published comparative studies have been conducted to evaluate the efficacy and safety of intraoperative mitomycin C (MMC) in endoscopic dacryocystorhinostomy (EN-DCR). However, results have not always been consistent. Therefore, we carried out a meta-analysis to compare the clinical results of EN-DCR with and without MMC. METHODS AND FINDINGS A comprehensive literature ...

The crosstalk is always an issue for 3D displays, a digital image processing methods we proposed.optical crosstalk in 3D displays that could further reduce. MZ-DCR method is not only based on the software approach,but pixel structure also using 3D displays. 3D display with 2DIG panel was used to demonstrate a improvement of MZ-DCR method.
