PURPOSE Both the tip and the tunneled segment of removed tunneled jugular catheters were cultured to determine whether there is a difference between both cultures in diagnosis of the catheter infections. The role of interventional radiology in prevention, diagnosis, and management of the tunneled catheter infections is also discussed. MATERIALS AND METHODS In this prospective study, 22 tunnel...

Neuronal migration involves coordinated extension of the leading process and translocation of the soma, but the relative contribution of different subcellular regions, including the leading process and cell rear, in driving soma translocation remains unclear. By local manipulation of cytoskeletal components in restricted regions of cultured neurons, we examined the molecular machinery underlyin...

Characteristics of rotor blade tip clearance flow in axial compressors can significantly affect their performance and stable operation. It may also increase blade vibrations and cause detrimental noises. Therefore, this paper is contributed to investigate tip leakage flow in a low speed isolated axial compressor rotor blades row. Simulations are carried out on near-stall condition, which is val...

The proline (Pro) concentration increases greatly in the growing region of maize (Zea mays L.) primary roots at low water potentials (psiw), largely as a result of an increased net rate of Pro deposition. Labeled glutamate (Glu), ornithine (Orn), or Pro was supplied specifically to the root tip of intact seedlings in solution culture at high and low psiw to assess the relative importance of Pro...

BACKGROUND Between January and June, 2015, a large typhoid fever outbreak occurred in Kampala, Uganda, with 10,230 suspected cases. During the outbreak, area surgeons reported a surge in cases of typhoid intestinal perforation (TIP), a complication of typhoid fever. We conducted an investigation to characterize TIP cases and identify modifiable risk factors for TIP. METHODS We defined a TIP c...

In this study we describe a preparation in which we examined directly, using tight-seal whole-cell recording, sodium currents from embryonic Drosophila neurons maintained in culture. Sodium currents were expressed in approximately 65% of the neurons prepared from wild-type Drosophila embryos when examined at room temperature, 24 hr after plating. While current density was low, other features of...
