Discovery and verification of osteopontin and Beta-2-microglobulin as promising markers for staging Human African Trypanosomiasis
(The American Society for Biochemistry and Molecular Biology, 2010)Human African trypanosomiasis, or sleeping sickness, is a parasitic disease endemic in sub-Saharan Africa, transmitted to humans through the bite of a tsetse fly. The first or hemolymphatic stage of the disease is ... -
Evaluation of the adverse effects of Dracaena steudneri Engl. stem bark aqueous extract in Wistar rats
(Academic Journals, 2021)Safety of medicinal plants/products is one of the major areas that require more attention because of the high rate at which consumers use medicinal plants/products due to their availability and accessibility. Dracaena ... -
General large deviations of longest gaps in homogeneous Poisson processes
(Elsevier, 2020)Let (N(t))t≥0 be a homogeneous Poisson process with unit intensity. The longest gap L(t)of this process is the maximal time subinterval between epochs of arrival times up to time t, and it finds applications in the theory ... -
Glycerol carbonylation with CO2 to form glycerol carbonate: A review of recent developments and challenges
(Elsevier, 2021-10)The utilization of CO2 as a feedstock to produce valuable chemical products is an important area of research in the field of sustainable chemistry and climate change. It addresses the challenge of rising CO2 atmospheric ... -
