Significance of pyrolytic temperature, application rate and incubation period of biochar in improving hydro-physical properties of calcareous sandy loam soil
( Springer Nature , 2024 , Article)Biochar is increasingly recognized for its ability to enhance hydro-physical properties of soil, offering promising solutions for improving soil structure, water retention, and overall agricultural productivity. In this ... -
SIRT1, a novel transcriptional downstream target of CD44, linking its deacetylase activity to tumor cell invasion/metastasis
( Frontiers Media S.A. , 2022 , Short Survey)Our tetracycline-off-inducible CD44 expression system previously established in mouse model, revealed that activation of CD44 with its major ligand hyaluronan (HA) promoted breast cancer (BC) metastasis to the liver. To ... -
Smart Synthesis of Trimethyl Ethoxysilane (TMS) Functionalized Core–Shell Magnetic Nanosorbents Fe3O4@SiO2: Process Optimization and Application for Extraction of Pesticides
( MDPI AG , 2020 , Article)In the current study, a smart approach for synthesizing trimethyl ethoxysilane–decorated magnetic-core silica-nanoparticles (TMS-mcSNPs) and its effectiveness as nanosorbents have been exploited. While the magnetite core ... -
Socio-cultural relationship between recreational sea anglers and blue sharks (Prionace glauca) in the United Kingdom
( Elsevier Ltd , 2023 , Article)The blue shark (Prionace glauca) is commonly caught by recreational anglers around the United Kingdom (UK) – part of a population (North Atlantic) which has sustained declines of > 50% over the last three generations (36 ... -
SOD2, a Potential Transcriptional Target Underpinning CD44-Promoted Breast Cancer Progression
( MDPI , 2022 , Article Review)CD44, a cell-adhesion molecule has a dual role in tumor growth and progression; it acts as a tumor suppressor as well as a tumor promoter. In our previous work, we developed a tetracycline-off regulated expression of CD44’s ... -
Soil moisture effects on leaf litter decomposition and soil carbon dioxide efflux in wetland and upland forests
( Soil Science Society of America , 2014 , Article)This study examined, first, the response of litter decomposition and soil CO2 efflux (RS) to different soil moisture conditions and, second, the application of various litter decomposition functions in a wetland and upland ... -
Solar cultivation of microalgae in a desert environment for the development of techno-functional feed ingredients for aquaculture in Qatar
( Elsevier , 2022 , Article)The demand for aquaculture feed will increase in the coming years in order to ensure food security for a growing global population. Microalgae represent a potential fish-feed ingredient; however, the feasibility of their ... -
