Knockout mice: Is it just genetics? Effect of enriched housing on fibulin-4+/- mice
( Public Library of Science , 2007 , Article)Background. Fibulin-4 is an extracellular matrix protein expressed by vascular smooth muscle cells that is essential for maintaining arterial integrity. Fibulin-4-/- mice die just before birth due to arterial hemorrhage, ... -
KYNU, a novel potential target that underpins CD44-promoted breast tumour cell invasion
( Blackwell Publishing Inc. , 2021 , Article Review)Using a validated tetracycline-off-inducible CD44 expression system in mouse model, we have previously demonstrated that the hyaluronan (HA) receptor CD44 promotes breast cancer (BC) metastasis to the liver. To unravel the ... -
Large dugong (Dugong dugon) aggregations persist in coastal Qatar

Larval hatching and development of the wedge shell (Donax trunculus L.) under increased CO2 in southern Portugal
( Springer Verlag , 2016 , Article)Noticeable changes in global temperatures, climate and ocean carbon chemistry are the result of carbon dioxide increase in the atmosphere. This increase has been mitigated by the oceans capacity to absorb one-fourth of the ... -
Laundry wastewater treatment using ultrafiltration under different operating conditions
( American Institute of Physics Inc. , 2018 , Conference Paper)The laundry wastewater of one of the hospitals in Qatar was selected and studied. It was found that hospital laundry is releasing considerable amount of wastewater i.e. 1800 - 2500 liters/cycle while washing 40 - 50 kg of ... -
Lead (Pb) bioaccumulation and antioxidative responses in Tetraena qataranse
( Nature Research , 2020 , Article)Lead (Pb) is the second most toxic metal on Earth and is toxic to humans and other living things. In plants, Pb commonly inhibits growth when it is at a concentration in the soil of 30�mg/kg or more but several Pb tolerant ... -
The Ligon lintless-2 Short Fiber Mutation Is Located within a Terminal Deletion of Chromosome 18 in Cotton<sup>1</sup>
( American Society of Plant Biologists , 2020 , Article)Extreme elongation distinguishes about one-fourth of cotton (Gossypium sp.) seed epidermal cells as “lint” fibers, useful for the textile industry, from “fuzz” fibers (,5 mm). Ligon lintless-2 (Li2), a dominant mutation ... -
Lipid transfer proteins (Ltps)- structure, diversity and roles beyond antimicrobial activity
( MDPI , 2021 , Article Review)Lipid transfer proteins (LTPs) are among the most promising plant-exclusive antimicrobial peptides (AMPs). They figure among the most challenging AMPs from the point of view of their structural diversity, functions and ... -
Localized outbreaks of coral disease on Arabian reefs are linked to extreme temperatures and environmental stressors
( Springer , 2020 , Article)The Arabian Peninsula borders the hottest reefs in the world, and corals living in these extreme environments can provide insight into the effects of warming on coral health and disease. Here, we examined coral reef health ... -
Long-term employment intensity of sectoral output growth in Tunisia
( International Labour Office , 2016 , Article)This article examines the long-term ability of Tunisian industries to generate employment opportunities. Using a panel data set of 15 industries over 1983–2010, the authors estimate their long-run output–employment ... -
Low electro-synthesis potentials improve permselectivity of polymerized natural phenols in biosensor applications
( Elsevier , 2017 , Article)First-generation amperometric biosensors are often based on the electro-oxidation of oxidase-generated H2O2. At the applied potential used in most studies, other molecules such as ascorbic acid or dopamine can be oxidized. ... -
Macrobenthos in the central Arabian Gulf: a reflection of climate extremes and variability
( Springer International Publishing , 2016 , Article)The arid subtropical ecosystem of the central Arabian Gulf was used to explore the combined effects of low primary productivity, high salinities, and variable temperatures on the composition and structure of benthic ... -
Maintaining the genetic health of putative Barbary lions in captivity: an analysis of Moroccan Royal Lions
( Springer Berlin / Heidelberg , 2009 , Article)The last representatives of the Barbary lion (Panthera leo leo), once numerous in North Africa but exterminated from the wild by the 1940s, are believed to be the captive lions descended from the Moroccan Royal Collection, ... -
A MALDI-TOF study of bio-remediation in highly weathered oil contaminated soils
( Elsevier , 2018 , Article)We have shown that Bacillus cereus is dominating the bacterial population at three polluted oil-industry sites where weather and soil conditions are extreme in terms of temperature, UV-radiation and salinity. A minor ... -
Man-made impact on the geochemistry of the Nile delta lakes. A study of metals concentrations in sediments
( Kluwer Academic Publishers , 2004 , Article)Forty two sediment samples were collected from four River Nile northern delta lakes (Mariut, Edku, Burullus and Manzalah) to asses the man-made impact on their environment during the last 20 years. Due to the continuous ... -
Manganese-Loaded Activated Carbon for the Removal of Organosulfur Compounds from High-Sulfur Diesel Fuels
( WILEY-VCH Verlag , 2014 , Article)The adsorptive capacity of activated carbon (AC) is significantly enhanced toward weakly interacting organosulfur compounds (OSC) from sulfur-rich diesel fuel. Sulfur compounds are selectively removed from diesel after ... -
