Organophosphorus (OP) nerve agents are a serious threat to military and civilian personnel, so rapid detection of OP compounds in all of these forms is of paramount importance to prevent casualties. Recently, we combined porous polyurethane foam formed in situ from water-miscible hydrophilic urethane prepolymers and enzymes such as ChEs. One of the advantages of this technique imparted to the i...

BACKGROUND In 2000, the Dutch Association of Occupational Physicians published a national guideline for the management of employees with mental health problems. OBJECTIVES To examine predictors of adherence to this guideline by Dutch occupational physicians (OPs). METHODS Using the Theory of Planned Behaviour, a questionnaire was developed about self-reported guideline adherence of OPs and ...

A segment of DNA located between 131 and 311 base pairs (bp) upstream from the transcriptional start of the Myxococcus xanthus ops gene (-131 to -311) was shown to function as an upstream activation site (UAS) for developmentally regulated transcription from the tps gene promoter region. The activation of early developmental transcription by the ops UAS was independent of orientation and could ...

The phloem is a vascular strand that conducts photoassimilates and systemic signals throughout the plant to coordinate growth. To date, few molecular genetic determinants have been identified to control both specification and differentiation of this tissue [1-3]. Among them, OCTOPUS (OPS) protein was previously identified as a polarly localized plasma membrane-associated protein of unknown bioc...

During a period of 10 months, inter and intraindividual variations in plasma cholinesterase (ChE) activity were studied in 331 employees of an organophosphorus insecticide factory, and in 193 healthy volunteers without occupational exposure to known ChE inhibitors. Repeated (n = 6) measurements of ChE activity and ChE substance concentration were performed in 410 subjects. The study showed subs...

In this paper we describe oPASS (Optical PAcket Switch Simulator), a simulation tool specifically designed for the evaluation of slotted Optical Packet Switching (OPS) switching architectures. oPASS is implemented in OMNET++, a general purpose eventdriven simulation framework. oPASS allows the evaluation of classical parameters in packet networks like packet loss probability and distribution of...

Chelerythrine (CHE), a natural benzo[c]phenanthridine alkaloid, shows anti-cancer effect through a number of mechanisms. Herein, the effect and mechanism of the CHE-induced autophagy, a type II programmed cell death, in non-small cell lung cancer (NSCLC) cells were studied for the first time. CHE induced cell viability decrease, colony formation inhibition, and apoptosis in a concentration-depe...
