Blood Flow Disturbance and Morphological Alterations Following the Right Atrial Ligation in the Chick Embryo.
( Frontiers Media , 2022 , Article)Collectively known as congenital heart defects (CHDs), cardiac abnormalities at birth are the most common forms of neonatal defects. Being principally responsible for the heart's pumping power, ventricles are particularly ... -
Antibacterial and Antibiofilm Activity of Mercaptophenol Functionalized-Gold Nanorods Against a Clinical Isolate of Methicillin-Resistant Staphylococcus aureus
( Springer , 2022 , Article)Gold nanorods (AuNRs) were synthesized by the seed-mediated wet chemical method using a binary surfactant system. AuNRs were stabilized with polyethylene glycol, then functionalized with 4-mercaptophenol (4-MPH) ligand by ... -
Advancing male age differentially alters levels and localization patterns of PLCzeta in sperm and testes from different mouse strains
( Medknow Publications , 2021 , Article)Sperm-specific phospholipase C zeta (PLC) initiates intracellular calcium (Ca2+) transients which drive a series of concurrent events collectively termed oocyte activation. Numerous investigations have linked abrogation ... -
Burden and disease pathogenesis of influenza and other respiratory viruses in diabetic patients
( Elsevier , 2022 , Article Review)Over the past two decades, diabetes mellitus (DM) has been receiving increasing attention among autoimmune diseases. The prevalence of type 1 and type 2 diabetes has increased rapidly and has become one of the leading ... -
Pyridoxine non-responsive p.R336C mutation alters the molecular properties of cystathionine beta-synthase leading to severe homocystinuria phenotype
( Elsevier , 2022 , Article)The prevalence of homocystinuria in Qatar is 1:1800, mainly due to a founder missense mutation p.R336C. • The cystathionine beta-synthase (CBS) R336C mutant was bacterially expressed, purified and its molecular properties ... -
