Tottering (tg) is an autosomal recessive mutation of the calcium channel alpha1A subunit in the mouse that results in epileptic spike and wave discharges, mild ataxia and paroxysmal episodes of involuntary spasms of the limbs, trunk and face. These convulsions have been especially difficult to characterize because of their unpredictable occurrence and lack… (More)
We have refined the map positions and identified molecular markers for three neurological mutations in the mouse, tottering (tg), Purkinje cell degeneration (pcd), and nervous (nr). These mutations were localized using simple sequence length polymorphisms between the mouse strain on which the mutation arose and the inbred strain onto which the mutation was… (More)
Tottering mice inherit a recessive mutation of the calcium channel alpha1A subunit that causes ataxia, polyspike discharges, and intermittent dystonic episodes. The calcium channel alpha1A subunit gene encodes the pore-forming protein of P/Q-type voltage-dependent calcium channels and is predominantly expressed in cerebellar granule and Purkinje neurons… (More)
Tottering (tg) mice inherit a recessive mutation of the calcium channel alpha 1A subunit gene, which encodes the pore-forming protein of P/Q-type voltage-sensitive calcium channels and is predominantly expressed in cerebellar granule and Purkinje neurons. The phenotypic consequences of the tottering mutation include ataxia, polyspike discharges, and an… (More)
One hundred thirty consecutive patients who underwent mitral valve replacement (MVR) or MVR with coronary artery bypass grafting (CABG) using cold crystalloid cardioplegic solution were analyzed to determine operative mortality and risk factors. Twenty-eight patients had mitral stenosis (MS), 37 had mitral regurgitation (MR), 37 had mixed MS and MR, 23 had… (More)
Spontaneous neurologic mutations in the mouse provide powerful tools for the study of mammalian central nervous system development. The study of mouse neurologic mutants has led to a better understanding of the complex mechanisms involved in the development of the nervous system. Because few of these mutations have been identified, molecular probes… (More)
A case of pancreatic abscess associated with Achromobacter biovar 1 in a 75-year-old man with multiple predisposing debilitating conditions is presented. The infection responded to antibiotic therapy, but the patient died from unrelated causes.
