A native, highly efficient microcystin-LR (MC-LR)-degrading bacterium named a7 was isolated from Lake Taihu and identified as Sphingopyxis sp. by 16S rDNA sequence analysis. The strain a7 could totally degrade MC-LR at a rate of 3.33 mg/(L•h), as detected by high-performance liquid chromatography (HPLC). The mlrA, mlrC, and mlrD genes were detected in the strain a7 by sequence analysis. Tetrape...

In this paper, we propose a method for constructing bigram LR tables by way of incorporating bigram constraints into an LR table. Using a bigram LR table, it is possible for a GLR parser to make use of both bigram and CFG constraints in natural language processing. Applying bigram LR tables to our GLR method has the following advantages: (1) Language models utilizing bigram LR tables have lower...

In this issue of the journal, Azzam and colleagues review the validation study of a clinical prediction rule for termination of resuscitation in patients suffering an out-of-hospital cardiac arrest. The clinical prediction rule is similar to a diagnostic test in that it predicts whether or not the patient will suffer the disorder of interest, in this case death, before hospital discharge. Given...

This study presents performance of upflow anaerobic sludge blanket (UASB) reactor in treating liquefied fleshings (LFs) with tannery wastewater (TWW) using liquefaction reactor (LR). With increase in recirculation rate, methane production increased in LR than in UASB reactor due to methanogenic bacteria in LR. UASB reactor with continuous feeding of LFs and TWW resulted with cumulative methane ...

Microcystin-LR (MCYST-LR), a hepatotoxin produced by cyanobacteria, inhibited purified protein phosphatases (PrPs) from rabbit skeletal muscle and the enzymes from Aplysia with an IC50 of approximately 10(-10) M. MCYST-LR also prolonged both serotonin- (5-HT) and cyclic adenosine monophosphate-induced inward currents in sensory neurons of Aplysia. These results, which are consistent with inhibi...

OBJECTIVE The goal of this study was to investigate the effect of hypertonic saline with 6% Dextran-70 (HSD) resuscitation on organ damage and the resuscitation efficiency of the combination of HSD and lactated ringers (LR) in a model of hemorrhage shock in dogs. METHODS Beagles were bled to hold their mean arterial pressure (MAP) at 50 ± 5 mmHg for 1 h. After hemorrhage, beagles were divided...

Accurate ranges from Earth to the Lunar Reconnaissance Orbiter (LRO) spacecraft Laser Ranging (LR) system supplement the precision orbit determination (POD) of LRO. LRO is tracked by ten LR stations from the International Laser Ranging Service (ILRS), using H-maser, GPS-steered Rb, and Cs oscillators as reference clocks. The LR system routinely makes oneway range measurements via laser time-of-...

An arc-sprayed amorphous Al–Ti–Ni coating on S355 structural steel was processed by laser remelting (LR) at powers of 600, 800, and 1000 W. The surface-cross-sectional morphologies, chemical element distributions, and phase compositions of the as-obtained Al–Ti–Ni coatings were analyzed using a scanning electron microscope (SEM), energy-dispersive spectrometer (EDS), and X-ray diffractometer (X...
