Benign familial neonatal convulsions (BFNC), a class of idiopathic generalized epilepsy, is an autosomal dominantly inherited disorder of newborns. BFNC has been linked to mutations in two putative K+ channel genes, KCNQ2 and KCNQ3. Amino acid sequence comparison reveals that both genes share strong homology to KvLQT1, the potassium channel encoded by(More)
Pin1, a peptidyl-prolyl isomerase binds to mitotic serine or threonine phosphoproteins. In Alzheimer's disease (AD) evidence points to the reactivation of mitosis in vulnerable neurons. Tangles composed of hyperphosphorylated tau contain phosphorylated Thr231 (pThr231 tau), which occurs to a greater extent in the AD brain than in the normal brain, and Pin1(More)
OBJECTIVE To determine the association between a composite measure of serological test results for common infections (Chlamydia pneumoniae, Helicobacter pylori, cytomegalovirus, and herpes simplex virus 1 and 2) and stroke risk in a prospective cohort study.

OBJECTIVES Thromboembolic complications are well recognized during the endovascular management of intracranial aneurysms. In this study, we present a case series of 40 patients with intraprocedural thrombotic complications who were treated with intra-arterial eptifibatide (IAE), and a review of the literature. METHODS Twenty-five patients with ruptured(More)
INTRODUCTION Reversible cerebral vasoconstriction syndrome presents with thunderclap headaches accompanied by mild neurologic deficits and is characterized by multifocal narrowing of the cerebral arteries that resolves over days to weeks. This syndrome may be idiopathic or occur in special contexts, most often involving adrenergic or serotonergic(More)
