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. …”

Study of performance, combustion, and emissions parameters of DI-diesel engine fueled with algae biodiesel/diesel/n-pentane blends by Elkelawy, Medhat

“…Due to the disadvantages of using pure biodiesel in engines, it was used as B50 (a blend of 50% diesel and 50% biodiesel). To enhance engine performance, n-pentane was used in different extents of 5, 10, and 15 ml per liter as an enhancer additive. …”

Pd nanocrystals encapsulated in MOF-derived Ni/N-doped hollow carbon nanosheets for efficient thermal CO oxidation: unveiling the effect of porosity by Ipadeola, Adewale K.

“…The obtained Pd/Ni-MOF-HNC possesses hollow carbon sheets with a great surface area (153.05 m2 g−1), pore volume (0.12 cm3 g−1), rich Pd/Ni-Nx active sites, Ni-metal defects, rich N-content (7.53 at%), mixed Pd/Ni-oxide phases, and uniformly distributed ultra-small Pd nanocrystals (7.03 ± 1.10 nm); meanwhile, Pd/Ni-MOF-NC formed without etching had no porosity and less Ni-metal defects. …”

High temperature thermal stability of innovative nanostructured thin coatings for advanced tooling by Cabibbo, Marcello

“…The main problem with steel, isthat itexhibits a relatively low hardness (below 10 GPa) which strongly decreases upon annealing above about 600 K.Thus, the majority of modern tools are nowadays coated with hard coatings that increase the hardness, decrease the coefficient of friction and protect the tools against oxidation. …”

EPIDEMIOLOGY OF CHLAMYDIA TRACHOMATIS IN LATIN AMERICA AND THE CARIBBEAN: SYSTEMATIC REVIEW, META-ANALYSES, AND META-REGRESSIONS by ABU-EL-RUZ, RASHA

“…We conducted random-effects meta-regressions to identify sources of heterogeneity and possible predictors of high prevalence. Results: The pooled-mean urogenital CT prevalence was 8.2% (95% CI: 7.5-9.1) for general populations, 14.0% (95%CI: 12.7-15.4) for female sex workers, 10.8% (95% CI: 8.4-13.4) for men who have sex with men, male sex workers, and transgenders, 16.1% (95% CI: 12.6-19.8) for symptomatic women, 25.4 (95% CI: 18.6-38.5) for symptomatic men, 9.7% (95%CI: 6.1-14) for HIV-positive individuals and individuals in HIV-discordant couples, and 11.9% (95 CI: 8.5-15.8) for STI clinic attendees. …”
