CLINICAL AND ECONOMIC IMPACT OF GENETIC AND NON-GENETIC FACTORS ON INR NORMALIZATION IN PRE-OPERATIVE MANAGEMENT OF WARFARIN PATIENTS by ELJILANY, ISLAM AHMED SAYED AHMED

“…To optimize the period of preprocedural warfarin interruption to decrease the incidence of bleeding in case of bridging and the incidence of thromboembolism in case of non-bridging, a study was conducted to determine the influence of CYP2C9, VKORC1, CYP4F2, FII, and FVII genetic polymorphisms and non-genetic factors on INR decline in a cohort of Arabs undergoing a procedure that requires warfarin interruption and developing an algorithm to tailor the duration of warfarin interruption before the procedure. …”

Gaining or losing team ball possession: The dynamics of momentum perception and strategic choice in football coaches by Briki, Walid

“…Nonetheless, both variables displayed asymmetrical effects, in the sense that: (1) the strength of positive PM appeared to be easier to decrease than to increase; and (2) the greater the positive PM (or the negative PM), the lesser (or the greater) the coaches' tendency to make a change in the organization of their teams. …”

Nanoclay compatibilization of phase separated polysulfone/polyimide films for oxygen barrier by Ammar, Ali

“…Thermal decomposition (TGA) measurements of PSF/PI films showed a decrease in thermal stability upon adding C30B due to its surfactant modification, while film mechanical tensile modulus properties improved slightly by adding low concentration of C30B (~ 1 mass%), but higher nanoclay loading decreased tensile strength and elongation at break. …”

Pore networks to characterize formation damage due to fines at varied confinement and sand shape by Hannun, J.

“…Measures done using pore networks, showed that because of micro-fractures, permeability of the system can increase during hydrate production. This is in contrast to the other systems, where throat sizes shrunk, decreasing the permeability; because of fines migration toward the throats and the small sand grains dislocations. …”
