The clinical picture of a slowly progressive sensory and motor peripheral neuropathy with loss of tendon refl exes certainly fi ts the diagnosis (Burns 2004). The early sensory symptoms in the territory of individual peripheral nerves is compatible although they would also be consistent with a vasculitic neuropathy. The severe pain is unusual and, although not unknown in CIDP, is again more sug...

Myocardial scar formation impairs heart function by inducing cardiac remodeling, decreasing myocardial compliance, and compromising normal electrical conduction. Conversion of myocardial scar fibroblasts (MSFs) into (functional) cardiomyocytes may be an effective alternative treatment to limit loss of cardiac performance after myocardial injury. In this study, we investigated whether the phenot...

OBJECTIVE To test the hypothesis proposed in a recent French study that a history of recurrent otitis media (OM) in childhood increases susceptibility to hearing loss from frequent exposure to a personal stereo (PS) during development to early adulthood. METHODS A subcohort of 358 young adults selected from a historic cohort study, all 18 years old and with a well-documented OM history (secre...

IMPORTANCE Middle ear disease is the primary cause of hearing loss in children and has a significant impact on language development and academic performance. Multiple prognostic factors have previously been examined, but there is little published data regarding frequency-specific hearing outcomes. OBJECTIVE To examine the relationship between type I tympanoplasty in a pediatric population and...

Multilevel inverters , covering a wide power range are currently considered as a better industrial solution for high dynamic performance and power-quality demanding applications. In this converter ,for specific time intervals fewer switches will be conducting so switching loss is also reduced . To generate gating signal Phase Disposition Pulse Width Modulation (PDPWM) technique is used here. Th...

Insertion of a dc-dc converter between the automobile battery and electrical loads is proposed. This would allow gradual conversion to higher battery voltage, regulation of dc distribution voltage, and multiple distribution voltage levels. Switching loss arising from parasitic inductances is a serious problem in this application. The nonlinear resonant switch can remove this source of loss, ach...

OBJECTIVES Bone-anchored implantable hearing devices are widely accepted as a surgical option for certain types of hearing loss in both adults and children. Most commercially available devices involve a percutaneous abutment to which a sound processor attaches. The rate of complications with such bone conduction systems is greater than 20%. Most complications arise from the abutment. Recently, ...

This paper presents the impedance study of low acyl gellan gum/poly(vinyl pyrrolidone) blend as a host matrix for ion conduction. Low salt content of lithium perchlorate was added into the blend polymer host and the membranes were prepared by the means of solution casting method. The temperature-conductivity of the investigated samples follows the Vogel-Tamann-Fulcher rule. The occurrence of el...
