Surgical Care Processing in Major Oklholma City Hosptal: The Surgeons' Perspective.

Purpose: This study aimed to assess processing of surgical care provided at major Oklahoma City hospitals based on surgeons'perception.

Methods: A questionnaire was sent out to Oklahoma County Medical Society surgeons using survey monkey to assess surgeons' perception of surgical care provided by major hospitals in Oklahoma City metropolitan area. The email contained a short introduction of study and the general aim of the study.

Biodistribution and safety assessment of AAV2-GAD following intrasubthalamic injection in the rat.

Background: The steps necessary to translate promising new biological therapies to the clinic are poorly documented. For gene therapy, there are unique aspects that need to be addressed in biodistribution studies. Notably, the spread of the vector beyond the intended target cells or tissue may result in persistent unwanted biological activity or unpredictable biological events; thus, it is critical to evaluate the risks associated with viral vector-mediated gene transfer prior to embarking on human clinical trials.

Imaging and manipulation of the competing electronic phases near the Mott metal-insulator transition.

The complex interplay between the electron and lattice degrees of freedom produces multiple nearly degenerate electronic states in correlated electron materials. The competition between these degenerate electronic states largely determines the functionalities of the system, but the invoked mechanism remains in debate. By imaging phase domains with electron microscopy and interrogating individual domains in situ via electron transport spectroscopy in double-layered Sr(3)(Ru(1-x)Mn(x))(2)O(7) (x = 0 and 0.

Probing electrical transport in individual carbon nanotubes and junctions.

The electrical transport properties of individual carbon nanotubes (CNTs) and multi-terminal junctions of CNTs are investigated with a quadraprobe scanning tunneling microscope. The CNTs used in this study are made of stacked herringbone-type conical graphite sheets with a cone angle of ∼20° to the tube axis, and the CNT junctions have no catalytic particles in the junction areas. The CNTs have a significantly higher resistivity than conventional CNTs with concentric walls.

Agglutination of Trypanosoma cruzi in infected cells treated with serum from chronically infected mice.

The protozoan parasite Trypanosoma cruzi is the causative agent of Chagas disease. The chronic stage of infection is characterized by a production of neutralizing antibodies in the vertebrate host. A polyclonal antibody, anti-egressin, has been found to inhibit egress of parasites from the host cell late in the intracellular cycle, after the parasites have transformed from the replicative amastigote into the trypomastigote.
