Electrical stimulation of neurons in the central nervous system of awake, behaving animals offers the ultimate test to determine whether the activation of specific neurons is sufficient to elicit perception, motor activity, or other behaviors. In this issue of Cell, Lima and Miesenböck (Lima and Miesenböck, 2005) dump the stimulating electrode in favor of a new remote control system to excite s...

Left main coronary artery atresia (LMCAA) is a rare congenital malformation with a nonspecific and varied clinical presentation. Ventricular dysfunction and mitral insufficiency are expected ischemic consequences in the neonatal period. Left internal mammary artery (LIMA) bypass grafting (CABG) is uncommon because of the technical difficulties in performing this procedure in neonates. We descri...

Rhizoctonia-like fungi were isolated from the infected roots of miniature rose (Rosa hybrida cv. Linda) plant with chlorosis and necrosis symptoms, grown in commercial glasshouse in Rafsanjan, Iran, during the autumn of 2011. All of the isolates were identified as binucleate Rhizoctonia sp. on the basis of hyphal characteristics and nuclei number. They were tested for detection of the anastomos...

The experiments in this report were designed to evaluate the effect of superficial temporal-middle cerebral artery (STA-MCA) anastomosis on the course of middle cerebral artery (MCA) occlusion by emboli while avoiding a vessel clipping technique as well as the use of long-acting barbiturate anesthesia. Dogs were divided into 3 general groups: A) embolus placement 1 h following anastomosis; B) e...

In this paper, making use of the well known generalized maximum principal according to Omori-Yau [20, 24] and considering the Laplacian of the integral of the warping function [4, 22], we prove some new Bernstein-type theorems concerning complete spacelike hypersurfaces immersed in semi-Riemannian warped products. Our main theorems extend the corresponding results proved by de Lima [13] and Aqu...

The left internal mammary artery (LIMA) is often used for the revascularization of the left anterior descending (LAD) coronary artery because of its long-term patency (1). In this report, we present a case of coil reocclusion of the unligated thoracic side branch of the LIMA in which recanalization occurred following coil occlusion procedure performed 4 years ago in a patient consuming warfarin...

Insurance companies are challenging to the implementation of data quality management. This presentation is the result of a project at Cosesp, a large insurance company in Brazil, and covers, as much as can be disclosed, several issues of real world data quality management implementations.

OBJECTIVE The main objective of this study was to describe Martin-Gruber anastomosis anatomically and to recognize its clinical repercussions. METHOD 100 forearms of 50 adult cadavers were dissected in an anatomy laboratory. The dissection was performed by means of a midline incision along the entire forearm and the lower third of the upper arm. Two flaps including skin and subcutaneous tissu...

OBJECTIVE To evaluate the immediate results of mechanical aorto-saphenous anastomosis compared with conventional anastomosis. METHOD We evaluated 12 patients. The mean age ranged from 62.33 +/- 7.30 years. Of 12 patients submitted to surgery without extracorporeal circulation, 10 (83.3%) patients were male. Thirty-three proximal anastomoses were evaluated, 21 of them being performed through t...
