Fluorescence spectroscopy is entrenched throughout the life sciences today and is used for a variety of applications, including the detection of chemical or biological analytes/species, in reporting molecular events or for the understanding of microenvironments, such as local viscosity, polarity and voltage measurements, to name but just a few. In the majority of these fluorescencebased measure...

The laboratory flux measurement system (LFMS) and dispersion models were used to investigate the kinetics of mercury emission flux (MEF) from contaminated soils. Representative soil samples with respect to total Hg concentration (26-9770 μg g(-1)) surrounding a decommissioned mercury-mining area (Las Cuevas Mine), and a former mercury smelter (Cerco Metalúrgico de Almadenejos), in the Almadén m...

The use of alternative extraction methods has increased since conventional have disadvantages like long processing time and limited yield. It is known that the yield enhanced, shortened by electric field. However, mathematical characterization electrically assisted processes needed for a better understanding improvement extraction. In this study, effects moderate field (MEF-E) parameters (frequ...

In the present study, the antiasthmatic (bronchodilatory) effect of the boiled extract of Nigella sativa in the airways of asthmatic patients was examined. The bronchodilatory effects of 50 and 100 mg/kg of boiled extract in comparison with 6 mg/kg theophylline were studied on 15 asthmatic patients. Pulmonary function tests (PFTs) including forced expiratory volume in one second (FEV(1)), peak ...

disc testing was used to determine antibiotic susceptibility and erythromycin resistance phenotypes. DNA from test samples was prepared by both Qiagen extraction and rapid boiling. As the efficiencies of the two methods were comparable, the rapid boiling method was used throughout. Primers were as published for erm(A), erm(B), erm(C), mef(A/E) 5 and erm(TR). 4 Donor and acceptor probe-pairs wer...

OBJECTIVE Piwil2, a member of Ago/Piwi gene family containing Piwi and PAZ domains, has been shown to be ectopically expressed in different cancer cells, especially its remarkable expression in cancer stem cells (CSCs), and is also known to be essential for germ line stem cell self-renewal in various organisms. The hypothesis that CSC may hold the key to the central problem of clinical oncology...
