( Qatar University , 2005 , Article)Soil yeasts including, Candida tropicalis, Geotrichum capitatum, Geotrichum candidum, Rhodotorula minuta and Rhodotorula rubra were isolated from soils of Saudi Arabia. The ability of these soil yeasts to solubilize insoluble ... -
Phospholipase C zeta and calcium oscillations at fertilisation: The evidence applications and further questions
( Elsevier Ltd , 2018 , Article)Oocyte activation is a fundamental event at mammalian fertilisation, initiated by a series of characteristic calcium (Ca2+) oscillations in mammals. This characteristic pattern of Ca2+ release is induced in a species-specific ... -
Phospholipase C zeta profiles are indicative of optimal sperm parameters and fertilisation success in patients undergoing fertility treatment.
( wiley , 2020 , Article)Oocyte activation is driven by intracellular calcium (Ca ) oscillations induced by sperm-specific PLCζ, abrogation of which causes oocyte activation deficiency in humans. Clinical PLCζ investigations have been limited to ... -
Phospholipid fatty acid composition of nine marine sponges from Qatar
( IFREMER , 1998 , Conference Paper)Phospholipid fatty acid composition was studied in sponge from Qatar including eight Demospongia and one Calcarea. More than 60 fatty acids were identified in each species as methyl esters and N-acyl pyrrolidides by gas ... -
