Based on a stochastic differential equation model for a single genetic regulatory system, we examine the dynamical effects of noisy fluctuations, arising in the synthesis reaction, on the evolution of the transcription factor activator in terms of its concentration. The fluctuations are modeled by Brownian motion and α-stable Lévy motion. Two deterministic quantities, the mean first exit time (...

The introduction of easily deployed covered stents has made PCI safer. The homemade venous and PTFE covered stent were effective but not practical for sealing perforations. The novel pericardial covered stent graft goes back to a more natural covering and is more easily deployed.

Adequate adherence to medication confers benefits on patients with psychotic illness, but is difficult to achieve. Efficacy of medication influences adherence in patients in advanced phases of illness and may have a similar influence on patients with a first episode of psychosis (FEP). We assessed medication adherence and efficacy in 216 FEP patients at program entry and at 3 and 6 months later...

This paper introduces a new configuration of compact, triangular- and diamond-slotted, microstrip-fed, low-profile antenna for C/X band applications on polytetrafluoroethylene glass microfiber reinforced material substrate. The antenna is composed of a rectangular-shaped patch containing eight triangles and two diamond-shaped slots and an elliptical-slotted ground plane. The rectangular-shaped ...

We wished to replicate evidence that an experimental paradigm of speech illusions is associated with psychotic experiences. Fifty-four patients with a first episode of psychosis (FEP) and 150 healthy subjects were examined in an experimental paradigm assessing the presence of speech illusion in neutral white noise. Socio-demographic, cognitive function and family history data were collected. Th...

Results One patient with subclavian artery aneurysm underwent resection of the aneurysm and subclavian-axillary bypass surgery with brachial embolectomy using a polytetrafluoroethylene (PTFE) graft; whereas the other patient underwent resection of the aneurysm and subclavian-axillary bypass surgery with saphenous vein graft. In addition to resection of the aneurysm, three out of 6 patients with...

Rapid synthesis of oligodeoxyribonucleotides is described by a solid phase method. Polysterene grafted on the surface of polytetrafluoroethylene has been found to be an adequate support. The properties of the support were studied in the synthesis of a number of oligonucleotides 6 to 15 nucleotides long. A flow-type semi-automatic synthesizer has been used. Each nucleotide addition involves seve...

Coronary artery perforations are life-threatening complications with a poor outcome. Historically, if the perforation was not controlled using conservative methods such as prolonged balloon inflation and protamine administration, emergency cardiac surgery has been performed. However, several percutaneous methods including covered stents and embolization materials have emerged as therapeutic...
