Sub-classification of apraxia of speech in patients with cerebrovascular and neurodegenerative diseases.

Some studies have hypothesized that primary progressive apraxia of speech (ppAOS) consists of heterogeneous symptoms that can be sub-classified; however, no study has classified stroke-induced AOS (sAOS) and ppAOS according to common criteria. The purpose of this study was to elucidate the symptoms and relevant brain regions associated with sAOS and ppAOS for sub-classification. Participants included 8 patients with sAOS following lesions in the left precentral gyrus and/or underlying white matter, and 3 patients with ppAOS.

Progressive anterior operculum syndrome due to FTLD-TDP: a clinico-pathological investigation.

Pathological investigation of progressive anterior operculum syndrome has rarely been reported. We describe clinico-pathological findings in a patient with progressive anterior operculum syndrome. A 74-year-old right-handed man had noticed speech and swallowing difficulties 1 year previously.

Integral value of JT interval in magnetocardiography is sensitive to coronary stenosis and improves soon after coronary revascularization.

Background: Magnetocardiography (MCG) is sensitive to minute cardiac electric abnormalities, but its clinical utility in diagnosing ischemic heart disease (IHD) has not been established. The present study examined the usefulness of an integral MCG value of ventricular repolarization in patients with IHD.

Methods And Results: MCG was performed at rest in 14 patients with coronary stenosis >75% confirmed by coronary angiography (IHD group) using a 64-channel system, and then the sum of the 64-channel integral values of the QRS or JT intervals (QRSi and JTi, respectively) was calculated.

Calcium channel blockades exhibit anti-inflammatory and antioxidative effects by augmentation of endothelial nitric oxide synthase and the inhibition of angiotensin converting enzyme in the N(G)-nitro-L-arginine methyl ester-induced hypertensive rat aorta: vasoprotective effects beyond the blood pressure-lowering effects of amlodipine and manidipine.

Long-acting dihydropyridine calcium channel blockades have been shown to limit the progression of atherosclerosis and decrease the incidence of cardiovascular events in humans and animals. To investigate the vasoprotective effects beyond the blood pressure-lowering effects of these agents, amlodipine (20 mg/kg/ day) and manidipine (10 mg/kg/day) were administered by gavage to N(G)-nitro-L-arginine methyl ester (L-NAME)-induced hypertensive rats for 2 weeks. L-NAME treatment (0.

[A case of Gogi aphasia with predominantly left temporal and parietal lobe atrophy].

We report a 68-year-old right-handed Japanese woman who had a history of progressive difficulty in understanding speech and naming. Neuropsychological examination presented Gogi (word meaning) aphasia and impairment of semantic memory for some common objects. She also presented acalculia and mild constructional impairment.
