BACKGROUND Dacrocystorhinostomy (DCR) is an operation used to treat nasolacrimal duct obstruction. Essentially there are two approaches: external and endoscopic. Several modalities are used in endoscopic DCR; all aiming to improve success rate, reduce complications, and shorten operative time. Both kerrison punch and drill are widely used in endoscopic DCR with non-conclusive knowledge about di...

PURPOSE To determine the success rate of conventional dacryocystorhinostomy (DCR) and endoscopic DCR performed in patients with acute dacryocystitis. METHODS Records of patients with acute dacryocystitis and operated during 2007-2008 were reviewed. Patients who completed a follow-up of 60 months were included in our study. Demographic characteristics, surgery types, success rate, and follow-u...

Dacryocystorhinostomy (DCR) is the standard procedure for treatment of acquired nasolacrimal duct obstruction (NLDO), which can be performed with an external or endonasal approach. Numerous variations DCR have been described in literature that report varying rates success. The aim this study to describe approach and success rate DCR, nasal mucosa, bone lacrimal mucosa are sequentially removed.

Open-source platforms are very useful for development and experimentation in constraint programming. However, until recently, no such platform existed for distributed constraint programming. This paper presents DisChoco, a platform for distributed constraint programming. DisChoco is a Java library implemented using the Choco solver and simple agent communication infrastructure (SACI). DisChoco ...

[1] The dynamics of forest-atmosphere CO2 carbon isotope exchange were examined in a coniferous forest in Colorado, United States. Tunable diode laser absorption spectrometry provided extensive characterization of the carbon isotope content (dC) of CO2. Observed patterns in d C of forest air were associated with photosynthesis, respiration, and atmospheric boundary layer dynamics. Similar relat...

purpose : to report a case of retained silicone tube case report : we report a case of 48-year-old iranian lady who referred to the department of otolaryngology with 18 years history of epiphora and intermittent mucopurulant discharge from the left lacrimal canaliculi. she had external dacryocystorhinostomy (dcr) with silicon stenting for epiphora 18 years ago but epiphora had continued after s...

OBJECTIVE To study the relative frequency, causes, anatomical and functional outcomes and complications of dacryocystorhinostomy (DCR) in patients between the second and fifth decade of life. METHOD A retrospective, nonrandomized, interventional study of a clinical series of 12 patients who underwent DCR from March 2007 to March 2009, performed by a single surgeon, with an age range between 1...

To elucidate unknown mammalian peroxisomal enzymes and functions, we subjected M13 phage expressing fusions between the gene encoding protein VI and a rat liver cDNA library to an immunoaffinity selection process in vitro (biopanning) with the use of antibodies raised against peroxisomal subfractions. In an initial series of biopanning experiments, four different cDNA clones were obtained. Thes...

We report the stepwise assembly of supramolecular daisy chain rotaxanes (DCR) made of double-stranded DNA: Small dsDNA macrocycles bearing an axle assemble into a pseudo-DCR precursor that was connected to rigid DNA stoppers to form DCR with the macrocycles hybridized to the axles. In presence of release oligodeoxynucleotides (rODNs), the macrocycles are released from their respective hybridiza...
