BACKGROUND To evaluate the clinical efficacy and toxicity of single pemetrexed treatment compared with platinum-based pemetrexed doublet pemetrexed-based as first-line treatment for advanced nonsquamous nonsmall cell lung cancer (NS-NSCLC) in elderly Chinese patients. METHODS The study retrospectively reviewed 175 elderly Chinese patients with NS-NSCLC from June 2010 to September 2013: 90 pat...

INTRODUCTION Dacryocystorhinostomy (DCR) is the treatment of choice for nasolacrimal duct obstruction. Although external DCR is regarded as the gold standard, endoscopic DCR is evolving as an equally-effective alternative. Objectives To compare the success rate of treating nasolacrimal duct obstruction by endoscopic endonasal method compared to the conventional DCR surgery. Materials and method...

The dC values of atmospheric carbon dioxide (CO2) can be used to partition global patterns of CO2 source/sink relationships among terrestrial and oceanic ecosystems using the inversion technique. This approach is very sensitive to estimates of photosynthetic C discrimination by terrestrial vegetation (DA), and depends on d C values of respired CO2 fluxes (d CR). Here we show that by combining t...

In this paper, we propose and evaluate TCP-DCR. TCP-DCR makes simple modifications to the TCP congestion control algorithm to make it more robust to non-congestion events. The key idea here is to delay the congestion response of TCP for a short interval of time , thereby creating room for local recovery mechanisms to handle any non-congestion events that may have occurred. If at the end of the ...

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...
