Here is detailed a novel and low-cost experimental method for high-throughput automated fluid sample irradiation. The sample is delivered via syringe pump to a nozzle, where it is expressed in the form of a hanging droplet into the path of a beam of ionising radiation. The dose delivery is controlled by an upstream lead shutter, which allows the beam to reach the droplet for a user defined peri...

Skeletal muscle mitochondria play a specific role in many disease pathologies. As such, the measurement of oxygen consumption as an indicator of mitochondrial function in this tissue has become more prevalent. Although many technologies and assays exist that measure mitochondrial respiratory pathways in a variety of cells, tissue and species, there is currently a void in the literature in regar...

Reliability of the Widal tube agglutination test has been the subject of many controversies over the years. This study was performed to assess the effect of certain modifications on the performance of Widal test in a novel microplate assay. Sera from 37 patients (21 males; 16 females) (mean age 28 +/- 7 years) were tested in the Immunology Unit at King Khalid University Hospital, Riyadh. Among ...

This study was conducted to examine in vitro antibacterialpotential from seed methanol extract of Peganum harmala (L) against some fish pathogenic bacteria including Lactococcus garvieae, Aeromonas hydrophila, Yersinia ruckeri and Pseuodomonas putida isolated from diseased rainbow trout (Oncorhynchus mykiss). The antibacterial activity of extracts was evaluated using disc diffusion assay, m...

the present study attempted to introduce shared reading as one of the most effective techniques in cultivating the learners’ reading and writing abilities. to this end, 50 homogenous students were assigned to the control and experimental groups following the administration of a standardized english proficiency test. thenceforth, based on writing and reading pretest scores of the learners on a g...

this study seeks to examine how teachers’ educational background (those who have educated in tefl in comparison to those who have educated in literature) may influence their beliefs and attitudes on language learning, teaching and the teaching methods they apply in their classes. on a general basis, depending on teachers’ opinion, learning process might be seen as behavioristic, inductive, inte...

this study was an attempt to investigate whether teaching critical reading strategies had any significant effect on intermediate efl learners’ vocabulary retention. to fulfill the purpose of this study, 72 male and female students within the age range of 17 to 32 years studying at farzan and farzanegan language schools in tehran at intermediate level were selected from a total number of 114 par...

A simplified, microplate tissue culture procedure is described which facilitates neutralization antibody surveys on large numbers of sera. A comparison of the micromethod with that employing standard tube cultures indicates it to be as sensitive and far more economical.

Summary In the current plate tectonics paradigm, relative motions are assumed to remain unperturbed by temporal stress changes occurring during seismic cycle, whereby slowly built up along tectonic boundaries is suddenly released rapid fault slip earthquakes. However, direct observations that could challenge such a tenet have not been identified so far. Here we show rigid motion of whole Anatol...

Membrane fusion is a process of fundamental importance in biological systems that involves highly selective recognition mechanisms for the trafficking of molecular and ionic cargos. Mimicking natural membrane fusion mechanisms for the purpose of biosensor development holds great potential for amplified detection because relatively few highly discriminating targets lead to fusion and an accompan...
