Chinchona Alkaloid from Dendrosenecio kilimanjari subsp. cottonii
(Georg Thieme Verlag Stuttgart· New York, 1997-02)Investigation of the Tanzanian Dendrosenecio kilimanjari subsp. cottonii resulted in the isolation of the cinchona alkaloid, cinchonidine (2). Conversion of cinchonidine to deoxy-cinchonidine was achieved in high yield ... -
Antibiotic Resistance of Escherichia coli from Humans and Black Rhinoceroses in Kenya
(Springer US, 2019-12-07)Upsurge of antibiotic resistance in wildlife poses unprecedented threat to wildlife conservation. Surveillance of antibiotic resistance at the human–wildlife interface is therefore needed. We evaluated differences in ... -
Fundamental Investigation of Vesicle Bilayer Membrane Dynamics
(Western Michigan University, 2007)We studied the bilayer of vesicles from dimyristolyphosphatidylcholine (DMPC), using nitrobenzoxadiazole (NBD) probes, attached to the head (NBD-PE) and the tail (NBD-PC) of phospholipid derivatives. We characterized the ... -
