Comparison of treatment effects after total mandibular arch distalization with miniscrews vs ramal plates in patients with Class III malocclusion.

Introduction: This study aimed to compare treatment effects after total mandibular arch distalization with buccal interradicular miniscrews vs ramal plates in patients with Class III malocclusion.

Methods: The sample consisted of 40 patients with Class III malocclusion; 20 were treated with distalization via buccal miniscrews (age, 25.8 ± 7.

Angioplasty of middle cerebral artery stenosis improves recurrent hemichorea caused by basal ganglia hypoperfusion.

We report a case of intermittent hemichorea associated with severe stenosis in the proximal M1 portion of the middle cerebral artery. The movements disappeared after transluminal angioplasty and stenting with restoration of perfusion in the basal ganglia.

Isolated Weakness of Middle, Ring, and Little Fingers due to a Small Cortical Infarction in the Medial Precentral Gyrus.

SMALL CORTICAL STROKES CAN PRODUCE PREDOMINANT ISOLATED WEAKNESS IN A PARTICULAR GROUP OF FINGERS: radial or ulnar. The traditional views are of point-to-point representations of each finger to neurons located in the precentral gyrus of the motor cortex such that the neurons of the radial fingers are located laterally and those of the ulnar fingers are located medially. We present a case of isolated weakness of middle, ring, and little fingers due to a small cortical infarction in the medial precentral gyrus.

Comparison of the Protective Effect of Indole beta-carbolines and R-(-)-deprenyl Against Nitrogen Species-Induced Cell Death in Experimental Culture Model of Parkinson's Disease.

Background: The membrane permeability transition of mitochondria has been suggested to be involved in toxic and oxidative forms of cell injury. Mitochondrial dysfunction is considered to play a critical role in neurodegeneration in Parkinson's disease. Despite the suggestion that indole beta-carbolines may be neurotoxic, these compounds provide a protective effect against cytotoxicity of other neurotoxins.
