Radiation exposure to anaesthetists during endovascular procedures.

Medical radiation exposure increases the likelihood of cataract formation. A personal dosimeter was attached to the left temple of 77 anaesthetists during 45 endovascular aortic aneurysm repairs and 32 interventional neuroradiology procedures. Compared with interventional neuroradiology, the median (IQR [range]) total radiation dose emitted by fluoroscopic equipment was significantly lower during endovascular aortic aneurysm repair (4175 (3127-5091 [644-9761]) mGy than interventional neuroradiology (1420 (613-2424 [165-10,840]) mGy, p < 0.

Current international status of home hemodialysis.

Three times weekly home hemodialysis (HHD) was introduced shortly after the initiation of chronic hemodialysis (HD) treatment in 1960. HHD eliminates the need of transportation to and from the dialysis unit and by allowing patients to set their own dialysis schedule, decreases the burden of treatment on their personal and professional lives. HHD has been found more economical and more highly associated with better patient survival than in-center dialysis.

Differential regulation of Purkinje cell dendritic spines in rolling mouse Nagoya (tg/tg), P/Q type calcium channel (α1(A)/Ca(v)2.1) mutant.

Voltage dependent calcium channels (VDCC) participate in regulation of neuronal Ca(2+). The Rolling mouse Nagoya (Cacna1a(tg-rol)) is a spontaneous P/Q type VDCC mutant, which has been suggested as an animal model for some human neurological diseases such as autosomal dominant cerebellar ataxia (SCA6), familial hemiplegic migraine and episodic ataxia type-2. Morphology of Purkinje cell (PC) dendritic spine is suggested to be regulated by signal molecules such as Ca(2+) and by interactions with afferent inputs.

Developmental characteristics of dendritic spines in the dentate gyrus of Fmr1 knockout mice.

Fragile X Syndrome (FXS) is the most common form of inherited mental retardation. The neuroanatomical phenotype of adult FXS patients, as well as adult Fmr1 knockout (KO) mice, includes elevated dendritic spine density and a spine morphology profile in neocortex that resembles younger individuals. Developmental studies in mouse neocortex have revealed a dynamic phenotype that varies with age, especially during the period of synaptic pruning.
