Isolation and characterization of extracellular bioflocculants produced by bacteria isolated from Qatari ecosystems
(
POLISH SOCIETY OF MICROBIOLOGISTS
, 2008 , Article)
Compared with conventional synthetic flocculants, bioflocculants has special advantages such as safety, strong effect, biodegradable and harmlessness to humans and the environment, so they may potentially be applied in ...
Opposing calcium-dependent signalling pathways control skeletal muscle differentiation by regulating a chromatin remodelling enzyme
(
Nature Publishing Group
, 2015 , Article)
Calcium signalling is important for differentiation-dependent gene expression, but is also involved in other cellular functions. Therefore, mechanisms must exist to distinguish calcium signalling relevant to differentiation. ...
Impacts of CO2-induced seawater acidification on coastal Mediterranean bivalves and interactions with other climatic stressors
(
Springer Berlin Heidelberg
, 2014 , Article)
The effects of seawater acidification caused by increasing concentrations of atmospheric carbon dioxide (CO2), combined with other climatic stressors, were studied on 3 coastal Mediterranean bivalve species: the mussel ...
Cadmium-induced endothelial dysfunction mediated by asymmetric dimethylarginine.
(
Springer
, 2020 , Article)
Cadmium (Cd) is a naturally occurring toxic heavy metal with no known essential biological functions. Exposure to Cd increases the risk of cardiovascular disease by disrupting vascular homeostasis at the endothelium. The ...
Screening and identification of a Bacillus thuringiensis strain S1/4 with large and efficient insecticidal activities.
(
WILEY-VCH
, 2013 , Article)
The bacterium Bacillus thuringiensis was recognized for its entomopathogenic activities related to Cry and Cyt proteins forming the δ-endotoxins and some extracellular activities like the vegetative insecticidal proteins ...
On the diet of the Pharaoh Eagle Owl, Bubo ascalaphus (Savigny, 1809), in Qatar, with an overview of its feeding habits
(
Taylor and Francis Ltd.
, 2014 , Article)
The diet of Bubo ascalaphus in Qatar was assessed based on pellets collected from the first known nesting site of the species in the country. The pellets contained a total of 68 prey items, representing 9 different species: ...
Community structure and activity of a highly dynamic and nutrient-limited hypersaline microbial mat in Um Alhool Sabkha, Qatar
(
Public Library of Science
, 2014 , Article)
The Um Alhool area in Qatar is a dynamic evaporative ecosystem that receives seawater from below as it is surrounded by sand dunes. We investigated the chemical composition, the microbial activity and biodiversity of the ...
Selective inhibition of protein arginine methyltransferase 5 blocks initiation and maintenance of B-cell transformation
(
American Society of Hematology
, 2015 , Article)
Epigenetic events that are essential drivers of lymphocyte transformation remain incompletely characterized. We used models of Epstein-Barr virus (EBV)–induced B-cell transformation to document the relevance of protein ...
Evaluation of Satellite Retrievals of Chlorophyll-a in the Arabian Gulf
(
MDPI
, 2017 , Article)
The Arabian Gulf is a highly turbid, shallow sedimentary basin whose coastal areas have been classified as optically complex Case II waters (where ocean colour sensors have been proved to be unreliable). Yet, there is no ...
Production of Polyclonal and Monoclonal Antibodies Against the Bacillus thuringiensis Vegetative Insecticidal Protein Vip3Aa16
(
Springer International Publishing AG
, 2014 , Article)
The aim of this study is to establish a quantitative determination of the vegetative insecticidal protein Vip3A from the culture supernatant of Bacillus thuringiensis either by ELISA or by the conventional quantification ...
