Plant defensins: types, mechanism of action and prospects of genetic engineering for enhanced disease resistance in plants
( Springer Verlag , 2019 , Article Review)Natural antimicrobial peptides have been shown as one of the important tools to combat certain pathogens and play important role as a part of innate immune system in plants and, also adaptive immunity in animals. Defensin ... -
Optimizing textile dye removal by activated carbon prepared from olive stones
( Elsevier B.V. , 2019 , Article)Activated carbon prepared from black and green olive stones were successfully used as an adsorbing agent to remove methylene blue from water. Scanning electron microscopy showed how the deep abundant cavities were occupied ... -
Identification and overcome of limitations of weathered oil hydrocarbons bioremediation by an adapted Bacillus sorensis strain
( Academic Press , 2019 , Article)Because of the high production of oil and gas in Qatar, the likelihood of oil spill occurrence is most probably susceptible to happen. Contaminated soil treatment is very expensive. Cost effective mechanisms are investigated ... -
Post K-Pg diversification of the mammalian order Eulipotyphla as suggested by phylogenomic analyses of ultra-conserved elements
( Academic Press Inc. , 2019 , Article)The origin of the mammalian order Eulipotyphla has been debated intensively with arguments around whether they began diversifying before or after the Cretaceous-Palaeogene (K-Pg) boundary at 66 Ma. Here, we used an in-solution ... -
Occurrence of epibenthic dinoflagellates in relation to biotic substrates and to environmental factors in Southern Mediterranean (Bizerte Bay and Lagoon, Tunisia): An emphasis on the harmful Ostreopsis spp., Prorocentrum lima and Coolia monotis
( Elsevier B.V. , 2019 , Article)Harmful events associated with epibenthic dinoflagellates, have been reported more frequently over the last decades. Occurrence of potentially toxic benthic dinoflagellates, on the leaves of two magnoliophytes (Cymodocea ... -
Unmasking the interplay between mTOR and Nox4: novel insights into the mechanism connecting diabetes and cancer
( NLM (Medline) , 2019 , Article)Cancer was recently annexed to diabetic complications. Furthermore, recent studies suggest that cancer can increase the risk of diabetes. Consequently, diabetes and cancer share many risk factors, but the cellular and ... -
Vertical distribution and radiological risk assessment of 137Cs and natural radionuclides in soil samples
( Nature Publishing Group , 2019 , Article)The aims of this study were to investigate the vertical distributions of natural radionuclides 232Th, 226Ra and 40K as well as anthropogenic radionuclide 137Cs in soil samples and to analyze the correlation among the ... -
The assessment of cadmium, chromium, copper, and nickel tolerance and bioaccumulation by shrub plant Tetraena qataranse
( Nature Publishing Group , 2019 , Article)Heavy metals constitute some of the most significant environmental contaminants today. The abundance of naturally growing Tetraena qataranse around Ras Laffan oil and gas facilities in the state of Qatar reflects its ... -
Adsorptive removal of mercury from water by adsorbents derived from date pits
( Nature Publishing Group , 2019 , Article)The current work presented here focuses on the remediation of mercury from water using modified low-cost materials. Modified date pits, low cost, minimal pretreatment steps and locally abundant agricultural waste materials ... -
Dataset of allelopathic effects of Casuarina equisetifolia-L leaf aquatic extract on seed germination and growth of selected plant crops
( Elsevier Inc. , 2019 , Article)In agricultural fields that are surrounded by dunes, the Casuarina tree is usually used as windbreaks. In addition, it plays a significant role in inhibiting nearby vegetation growth. In this dataset, the effect of Casuarina ... -
In-vitro application of a qatari burkholderia cepacia strain (QBC03) in the biocontrol of mycotoxigenic fungi and in the reduction of ochratoxin a biosynthesis by aspergillus carbonarius
( MDPI AG , 2019 , Article)Mycotoxins are secondary metabolites produced by certain filamentous fungi, causing human and animal health issues upon the ingestion of contaminated food and feed. Among the safest approaches to the control of mycotoxigenic ... -
Bone benefits of fish oil supplementation depend on its EPA and DHA content
( MDPI AG , 2019 , Article)The preventive effect of high-dose (9%) regular-fish oil (FO) against bone loss during aging has been demonstrated, but the effects of a low-dose (1%–4%) of a highly purified concentrated FO (CFO) has not been elucidated. ... -
Health risk assessment of Patulin intake through apples and apple-based foods sold in Qatar
( Elsevier Ltd , 2019 , Article)This is the first report on assessing the non-carcinogenic health risk associated with Patulin exposure in Qatar. The concentrations of Patulin, as determined in previous studies, in apples, apple juice, and apple-based ... -
Treatment of Sand Using Microbial-Induced Carbonate Precipitation (MICP) for Wind Erosion Application
( American Society of Civil Engineers (ASCE) , 2018 , Conference Paper)Microbial-induced carbonate precipitation (MICP) has been used to improve soil properties for different geotechnical applications. This research focuses on evaluating the use of MICP for the wind erosion application. The ... -
Potential of mercury-tolerant bacteria for bio-uptake of mercury leached from discarded fluorescent lamps
( Academic Press , 2019 , Article)In this study, ten bacterial strains were found to be mercury resistant after their isolation from Qatari coastal sediments. Tolerance was found to be up to 100–150 ppm for five strains. Those strains had optimum growth ... -
Database Facilitated Screening with NMR Spectroscopy Analysis for Drug Detection
( IEEE , 2019 , Conference Paper)© 2019 IEEE. Drug detection plays the key role in the enforcement of drug regulations. Various detection methods for them are thus developed. However, in most investigations, the most time-consuming and tedious part is not ... -
Usefulness of COMT gene polymorphisms in North African populations
