background chitosan is a naturally occurring biopolymer which has been widely used in a variety of biomedical applications including local antibiotic delivery due to its excellent mechanical properties, biodegradability and biocompatibility. beads are spherical, porous carriers which are prepared from various materials including chitosan. objectives the current study aimed to fabricate a new co...
The electromechanical responses to isoprenaline and a high calcium medium on cardiac muscles from nonhibernating and hibernating chipmunks were studied in the presence and the absence of ryanodine. In nonhibernating animal preparations, isoprenaline (5 X 10(-8) M) caused a marked positive inotropic effect with an increase in the amplitude of the action potential plateau and augmented the slow a...
Background & Aim: The role of ryanodine receptor(RYR) on pacemaker activity of heart cells is controversial. Some investigators have suggested that it is obligatory, while others believe it is partial and not obligatory. The principle aim of this study was once more to characterize the role of ryanodine receptor(RyR) on the pacemaker activity of the sinoatrial node(SAN) and the atrioventric...
