We report here a family with leukodystrophy clinical features of which are characterized as adult onset, probably autosomal dominant inheritance, hyperreflexia, cerebellar ataxia, autonomic dysfunction and no peripheral nerve involvement. T2-weighted brain MRI revealed diffuse high signal areas in the cerebral white matter. The disorder in our subjects can(More)
INTRODUCTION Middle cerebral artery (MCA) disease is the most common vascular lesion in stroke. Transcranial Doppler (TCD) is a non-invasive bedside screening method for assessing cerebral blood flow. AIM To investigate the prevalence of MCA stenosis in asymptomatic but high-risk individuals for stroke. MATERIALS AND METHODS Prospective study between(More)
X-linked cerebral creatine deficiency (MIM 300036) is caused by deficiency of the creatine transporter encoded by the SLC6A8 gene. Here we report three patients with this condition from Israel. These unrelated patients were evaluated for global developmental delays and language apraxia. Borderline microcephaly was noted in one of them. Diagnosis was(More)
BACKGROUND & OBJECTIVES Patients with rheumatoid arthritis (RA) are more prone for accelerated atherosclerosis and Asian Indians as an ethnic group are predisposed to a high risk of premature atherosclerosis. However, sparse data are available regarding the burden of atherosclerosis among asymptomatic adult patients with RA in south India. We studied the(More)
The effects of bucumolol (BUC), nadolol (NAD) and nifenalol (NIF) on contractile forces and on action potentials (APs) were investigated in isolated guinea pig atrial and papillary muscles, respectively. Log 1/ED40 values for the negative inotropic effects of these drugs were 0.097, 10 and 0.74 mmol/l in this order. BUC (50 mumol/l), NAD (0.5 mmol/l) and(More)
In embryonic chick hearts during development, there are three inward current systems which are involved in the rising phases of the action potentials (APs): fast INa, slow ICa, and tetrodotoxin-insensitive slow INa. To assess reactivation processes for these three types of inward current channels (fast Na+, slow Ca2+, and slow Na+ channels), diastolic(More)
In order to assess the effects of Bay-K-8644 on electrical activities of young embryonic chick hearts in which the rising phase of the action potential (AP) depends on tetrodotoxin-insensitive slow Na+ currents, slow AP were recorded in spontaneously beating 3-day-old embryonic chick hearts. Bay-K-8644(10(-6) mol/l) caused increases in the maximum rate of(More)
