(Elsevier, 2022-02-14)In this study, a new type of packaging film assembled by caffeic acid-grafted-chitosan/polylactic acid (CA-g-CS/PLA) was prepared, and its characteristics, migration properties and effect on the postharvest quality of ... -
Characteristics of urban agricultural farming practices and spatial nature of production systems in the city of Nairobi, Kenya
(RUFORUM, 2014)Within the urban environment, urban agriculture faces myriad of challenges ranging from type of practices employed, through to production systems, to quality and safety of produce. An investigation was done to characterise ... -
Characterization of climate variability and water harvesting system for crop production in Adulala Watershed, Central Rift Valley of Ethiopia
(HARAMAYA UNIVERSITY, 2015)Scarcity of water is the most severe constraint for traditional agriculture in semi-arid areas of Ethiopia. Precipitation is extremely variable, thus water harvesting is crucial for ensuring improved crop ... -
Characterization of ethylene biosynthesis and its regulation during fruit ripening in kiwifruit, Actinidia chinensis ‘Sanuki Gold’
(Elsevier, 2010)Ethylene biosynthesis in kiwifruit, Actinidia chinensis ‘Sanuki Gold’ was characterized using propylene, an ethylene analog, and 1-methylcyclopropene (1-MCP), an inhibitor of ethylene perception. In fruit harvested between ... -
Characterization of Ripening-related Genes Involved in Ethylene-independent Low Temperature-modulated Ripening in ‘Rainbow Red’ Kiwifruit during Storage and On-vine
(The Japanese Society for Horticultural Science, 2018)‘Rainbow Red’ kiwifruit have been reported to gradually ripen during low temperature storage and on the vine in the absence of detectable ethylene. This study was conducted to compare the expression of ripening-related ... -
Chemical and antioxidant characterization of Dovyalis caffra and Dovyalis abyssinica fruits in Kenya
(Elsevier, 2022-10-12)This study aimed at chemical characterization of Dovyalis caffra (Hook.f. & Harv.) Sim. and Dovyalis abyssinica (A. Rich.) Warb. fruits from Kinamba Town (KT) in Laikipia county and Gitoro Forest (GF) in Meru county of ... -
Chemotherapy of Second Stage Human African Trypanosomiasis: Comparison between the Parenteral Diamidine DB829 and Its Oral Prodrug DB868 in Vervet Monkeys
(PLOS, 2014)Human African trypanosomiasis (HAT, sleeping sickness) ranks among the most neglected tropical diseases based on limited availability of drugs that are safe and efficacious, particularly against the second stage (central ... -
Coenzyme Q10 prevented full blown splenomegaly and decreased melarsoprol-induced reactive encephalopathy in mice infected with Trypanosoma brucei rhodesiense
(Journal of Coastal Life Medicine, 1997)Objective: To establish the modulatory effects of coenzyme Q10 on experimental trypanosome infections in mice and evaluate the risk of occurrence and severity of melarsoprol-induced post treatment reactive encephalopathy ... -
A comparative evaluation of maturity indices of mango fruits produced in two contrasting agro-ecological zones of Kenya
(RUFORUM, 2014)Harvesting mango (Mangifera indica) fruits at the right stage for the destination market and use requires reliable maturity indices. There are various indices that are used to determine harvest maturity for mango fruits. ... -
Comparative Pathogenicity of Trypanosoma brucei rhodesiense Strains in Swiss white Mice and mastomys natalensis Rats
(2015)Abstract We evaluated Mastomys natelensis rat as an animal model for Rhodesian sleeping sickness. Parasitaemia, clinical and pathological characteristics induced by T. b. rhodesiense isolates, KETRI 3439, 3622 and 3637 ... -
Comparative transcriptome analysis reveals distinct ethylene – independent regulation of ripening in response to low temperature in kiwifruit
(BioMed Central, 2018)Kiwifruit are classified as climacteric since exogenous ethylene (or its analogue propylene) induces rapid ripening accompanied by ethylene production under positive feedback regulation. However, most of the ripening–associated ... -
Comparison of Freeze-Drying and Freeze-Drying Combined with Microwave Vacuum Drying Methods on Drying Kinetics and Rehydration Characteristics of Button Mushroom (Agaricus bisporus) Slices
(Springer, 2013)Button mushroom slices were dried using freeze-drying (FD) and freeze-drying combined with microwave vacuum drying (FD + MVD) methods. Drying parameters including drying temperatures (20, 30, and 40 °C), chamber pressures ... -
