Anomalous Diffusion in Purkinje Cell Dendrites Caused by Spines
We combined local photolysis of caged compounds with fluorescence imaging to visualize molecular diffusion within dendrites of cerebellar Purkinje cells. Diffusion of a volume marker, fluorescein dextran, within spiny dendrites was remarkably slow in comparison to its diffusion in smooth dendrites. Computer simulations indicate that this retardation is due to a transient trapping of molecules w...
متن کاملHigh-grade atrioventricular block caused by his-purkinje injury during contrast left ventriculography.
A68-year-old woman with exertional chest discomfort was referred for cardiac catheterization. Her medications did not include atrioventricular (AV) nodal blocking agents, and she had no prior history of dizziness or syncope. Her admission ECG was normal, including a normal axis, PR interval, and QRS morphology and duration (Figure 1). Right heart catheterization and coronary angiography demonst...
متن کاملThe acute liver injury in rat caused by gold nanoparticles
Objective(s): Gold nanoparticles (GNPs) command a great deal of attention for biomedical applications nowadays. The data about the degree of toxicity and the accumulation of gold nanoparticles in-vivo is not enough to judge. Materials and Methods: A total of 32 healthy male Wistar rats were randomly divided into 4 including: three GNP-treated and one control group. Groups 1, 2 and 3 receive...
متن کاملTraumatic urinary diversion caused by gunshot injury in a stallion
A seven-year-old stallion with diversion of urinary pass to the thigh due to a urethral fistula caused by gunshot perineal injury was presented to the Urmia University, Veterinary Teaching Hospital. No signs of urinary obstruction or renal failure were observed. Because of inaccessible location of the injured urethra, through a perineal urethrotomy incision, a urinary catheter was effectively a...
متن کاملCerebellar ataxia and Purkinje cell dysfunction caused by Ca2+-activated K+ channel deficiency.
Malfunctions of potassium channels are increasingly implicated as causes of neurological disorders. However, the functional roles of the large-conductance voltage- and Ca(2+)-activated K(+) channel (BK channel), a unique calcium, and voltage-activated potassium channel type have remained elusive. Here we report that mice lacking BK channels (BK(-/-)) show cerebellar dysfunction in the form of a...
