water soluble chitosan oligosaccharide (cho) was hydrophobically modified with camptothecin (cpt) in different molar ratios of cpt, and characterized by ft-ir and 1 h-nmr spectroscopy. nanomicelles prepared by these copolymers were analyzed for size, zeta, and length of time they remain stable. the critical micelle concentration (cmc) and dissociation of micelles at physiological ph and acidic ...

background: cytoadherence of plasmodium falciparum - infected red blood cells to endothelial cells is an important mechanism for parasite survival and a major trigger for diseases pathology. here, we de­scribe a new adhesion assay in which different cell types (cho, cho/cd36 and cho/icam-1) are at­tached to cytodex beads in a mini-column format to measure the relative sizes of various binding s...

UNLABELLED Carbohydrate-protein (CHO+Pro) beverages reportedly improve endurance and indices of muscle disruption, but it is unclear whether these effects are related to total energy intake or specific effects of protein. PURPOSE The authors examined effects of CHO+Pro on time to exhaustion and markers of muscle disruption compared with placebo (PLA) and carbohydrate beverages matched for car...

background although magnetic resonance spectroscopy (mrs) has been shown as an effective diagnostic tool in distinguishing inflammation from neoplasm in cystic brain lesions, the optimum approach in selecting the portions of lesions in mrs and the possible effects of different times of echoes (tes) remains unknown. objectives to determine the most effective te in diagnosing neoplastic lesions b...

background: radio-adaptive response and bystander effects are known phenomena occurring in cells following exposure to ionizing radiation (ir). in this study we examined possible radio-adaptation of lymphocytes following bystander effects induced by cho-k1 cells. materials and methods: whole blood and cho-k1 cells were cultured in rpmi-1640 complete medium. cells were separately irradiated with...

objective: to study the mechanisms involved in amyloid formation processes, we made a mammalian cell culture model of amylin aggregation and characterized its properties. materials and methods: amyloid fibrils were extracted from cho cells and binding affinity to thioflavin t and congo red was investigated. then the apple-green birefringence of extracted fibrils was detected under polarized li...
