It has been over a century since Sir Archibald Garrod first recognised the existence of inherited metabolic diseases (IMD).1 Technological and scientific advances have gradually led to greatly increased understanding of their aetiology and pathogenesis, and have ultimately resulted in effect...

Mobile learning involves use of mobile devices to participate in learning activities. Most elearning activities are available to participants through learning systems such as learning content management systems (LCMS). Due to certain challenges, LCMS are not equally accessible on all mobile devices. This study investigates actual use, perceived usefulness and user experiences of LCMS use on mob...

Fish skin mucus is the first line of defense that provides physical and chemical barriers against pathogens toxins. The produced continuously sloughed off regularly from to defend infections through skin. However, molecular properties content prevent pathogen invasion are yet be fully understood. In this study, a proteomic approach using liquid chromatography–mass spectrometry (LCMS) was applie...

this study propose a new analytical protocol for the determination of benzene, xylene, toluene and styrene in water samples using homogeneous liquid-liquid microextraction via flotation assistance (hllme-fa) technique followed by gas chromatography-mass spectrometry (gc-ms). in this research, a special extraction cell was designed to facilitate collection of the low-density solvent extraction. ...

Analytical methods employed for the determination of drugs and metabolites in biological matrices such as urine, plasma and serum are essential throughout drug discovery and development. It is well-known that, analytical techniques are constantly undergoing change and improvements and each analytical method has its own characteristics which may vary from analyte to analyte at different conditio...

the aim of this study was to investigate the removal of toluene from air through nano-graphene modified by ionic liquid (ng-il). the batch adsorption experiments in glass bottle of gas chromatography equipped with flame ionization detector (gc-fid) were used. graphene ultrahigh-quality synthesized by substrate-free gas-phase method in a single step and graphene sheets were deposited with ionic-...

[1] As part of the Large-Scale Biosphere-Atmosphere Experiment in Amazonia (LBA)Cooperative LBA Airborne Regional Experiment (CLAIRE) 2001 campaign in July 2001, separate day and nighttime aerosol samples were collected at a ground-based site in Amazonia, Brazil, in order to examine the composition and temporal variability of the natural ‘‘background’’ aerosol. We used a high-volume sampler to ...

Non-invasive hormone monitoring of endangered wildlife provides an essential tool to optimize breeding strategies, mainly in captive management. However, the protocol reproductive on pregnancy status using non-invasive faecal samples Malayan tapir is still inconclusive. Therefore, we compared metabolites hormones; 17β-oestradiol and progesterone extracted methods Schwarzenberger et al. (1996) (...
