Characterization of MXene as a Cancer Photothermal Agent Under Physiological Conditions
( Frontiers Media , 2021 , Article)A growing interest has recently emerged in the use of nanomaterials in medical applications. Nanomaterials, such as MXene, have unique properties due to their 2D ultra-thin structure, which is potentially useful in cancer ... -
Characterization of neurobehavioral pattern in a zebrafish 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced model: A 96-hour behavioral study
( Public Library of Science , 2022 , Article)Parkinson’s disease (PD) is the most common brain motor disorder, characterized by a substantial loss of dopaminergic neurons in the substantia nigra pars compacta (SNpc). Motor impairments, such as dyskinesia, bradykinesia, ... -
Characterization of Polymers in Dilute Solutions
( Qatar University , 1997 , Article)Basic moleculer characterisitics of polymers are: molecular architecture, molecular weight and size, and their distributions. All these characterisitics are derived from measurements of very dilute solutions. Methods of ... -
Characterization of polysulfone/diisopropylamine 1-alkyl-3-methylimidazolium ionic liquid membranes: high pressure gas separation applications
( Blackwell Publishing Ltd , 2020 , Article)Membrane separation is gaining great attention in many applications, especially in gas separation. Polysulfone (PSF) is the most widely studied polymeric membrane material for CO2 in its pure or modified state. Ionic liquids ... -
Characterization of regulatory sequences in alternative promoters of hypermethylated genes associated with tumor resistance to cisplatin
( Spandidos Publications , 2014 , Article)The development of cisplatin resistance in human cancers is controlled by multiple genes and leads to therapeutic failure. Hypermethylation of specific gene promoters is a key event in clinical resistance to cisplatin. ... -
Characterization of tbm muck for construction applications
( MDPI , 2021 , Article)This paper investigates the potential utilization of the Tunnel Boring Machine (TBM) muck generated from Doha's Metro Gold Line in different construction applications. The properties of the raw TBM muck were studied, and ... -
Characterization of the Efficacy of a Split Swine Influenza A Virus Nasal Vaccine Formulated with a Nanoparticle/STING Agonist Combination Adjuvant in Conventional Pigs
( Multidisciplinary Digital Publishing Institute (MDPI) , 2023 , Article)Swine influenza A viruses (SwIAVs) are pathogens of both veterinary and medical significance.
