Zidovudine treatment preferentially benefits persons with only non-syncytium-inducing (NSI) human immunodeficiency virus type 1 (HIV-1) variants. To understand this differential efficacy, changes in cellular virus load, clonal composition of HIV-1 populations, and development of resistance-conferring reverse transcriptase mutations were studied in 17 persons initiating zidovudine therapy. Zidov...
The current study examines the role of cognitive and perceptual loads in inattentional deafness (the failure to perceive an auditory stimulus) and the possibility to predict this phenomenon with ocular measurements. Twenty participants performed Air Traffic Control (ATC) scenarios-in the Laby ATC-like microworld-guiding one (low cognitive load) or two (high cognitive load) aircraft while respon...
conclusions the quite sensitive in-house taqman real time rt-pcr assay was able to detect and quantify all four main hcv genotypes prevailing around all geographical regions of iran. results the lower limit detection of this in-house hcv real-time rt-pcr was determined as 100 rna copies/ml. inter- and intra-assay coefficient of variation (cv) of this in-house hcv real-time rt-pcr ranged from 0....
Maglev is Google’s network load balancer. It is a large distributed software system that runs on commodity Linux servers. Unlike traditional hardware network load balancers, it does not require a specialized physical rack deployment, and its capacity can be easily adjusted by adding or removing servers. Network routers distribute packets evenly to the Maglev machines via Equal Cost Multipath (E...
The aim of the study was to investigate the possibility of using infrared (IR) thermography for assessing muscle fatigue during low effort. Three tests at constant levels of load 5, 15 and 30% of maximum voluntary contraction (MVC) lasting 5 min each were performed on a group of 10 men. Temperature and electromyographic (EMG) signal were registered from biceps brachii (BB). Analysis focused on ...
UNLABELLED PREMISE OF THE STUDY Invasive species are nonnative species that enter novel environments, establish sustained populations, and can negatively impact native species. Here we assess a potential weakness of invasive species (genetic load) and show how species might overcome genetic barriers. Colonization of novel habitats by invasive species typically involves few individuals, expos...
The purpose of this research is to analyse the long-term deformations reinforced concrete beams made recycled coarse aggregates (RCA), using four different replacement ratios, 0%, 20%, 50% and 100%. For said purpose, three loading stages were carried out: firstly, sustained load for 1300 days, secondly, unloading recovery where registered over a one year period, lastly, testing up failure in or...
the objective of research was to explore the suitability of lipids like compritol 888 ato and stearic acid as release retardant to develop sustained release (sr) tablets. the sr micromatrices of lipid (s) and glipizide were prepared (lm1- lm6) as intermediate product by fusion method and assessed for various pharmacotechnical properties. micromatrices were formulated as sr tablets (f1-f6) by di...
When people hear unexpected perturbations in auditory feedback, they produce rapid compensatory adjustments of their vocal behavior. Recent evidence has shown enhanced vocal compensations and cortical event-related potentials (ERPs) in response to attended pitch feedback perturbations, suggesting that this reflex-like behavior is influenced by selective attention. Less is known, however, about ...
Nerve root compression produces chronic pain and altered spinal neuropeptide expression. This study utilized controlled transient loading in a rat model of painful cervical nerve root compression to investigate the dependence of mechanical allodynia on load magnitude. Injury loads (0-110mN) were applied quasistatically using a customized loading device, and load thresholds to produce maintained...
