To conduct a kinetic study of paraquat (PQ), we investigated 9 patients with acute PQ intoxication. All of them ingested more than 20 ml of undiluted PQ herbicide to commit suicide and arrived at our hospital early, not later than 7 h after PQ ingestion. The urine dithionite test for PQ in all of the nine patients was strongly positive at emergency room. Blood samples were obtained every 30 min...

Paraquat (PQ) is a highly toxic herbicide that harms the liver, kidney, lungs and heart, and results in a variety of complications. The majority of patients with severe PQ poisoning may succumb to multiple organ failure, and the mortality rate is high. Although a large number of studies have been performed investigating PQ poisoning, cases of mumps caused by PQ-induced poisoning are rare. In th...

After PQ data of interest are obtained, a comprehensive PQ assessment can be carried out depending on the purpose of the study. This may include power system and equipment modeling verification, PQ problem mitigation and optimization, and data analysis [4,5]. In most cases, automated PQ assessment is desirable because manual analysis may be difficult to carry out due to lack of time and special...

In this paper, a data stream architecture is presented for electrical power quality (PQ) which is called PQStream. PQStream is developed to process and manage time-evolving data coming from the country-wide mobile measurements of electrical PQ parameters of the Turkish Electricity Transmission System. It is a full-fledged system with a data measurement module which carries out processing of con...

This paper deals with the power quality (PQ) improvement by using a transformer less Hybrid Active Power Filter (HAPF) based on a six switch two leg inverter with battery and solar system through boost converter which increases the reliability of power supply by reducing the Total Harmonic Distortion (THD) and increase the voltage level. The control methods of instantaneous reactive power theor...

Plastoquinone-9 (PQ-9) was isolated from the chloroplasts of Euglena gracilis Strain Z and spinach. The functional involvement and the structural specificity of PQ-9 in photochemical reactions was investigated in the isolated chloroplasts of Euglena gracilis. It was found that PQ-9 was required for both photoreduction of ferricyanide and photosynthetic phosphorylation in Euglena chloroplasts. T...

9, 10-Phenanthrenequinone (PQ) is regarded as a harmful environmental pollutant and its presence has been reported in atmospheric environment. The measurement of PQ in environment should be necessary to evaluate the influence of PQ on human health. We found that PQ reacted with 2-aminothiophenol under acidic condition to form fluorescent derivative which emits green fluorescence at 510nm. Based...

The plant Solanum nigrum treated with the pathogen Phytophthora infestans-derived elicitor responded by elevated reactive oxygen species (ROS) production, lipid peroxidation and lipoxygenase (EC 1.13.11.12) activity in comparison with control plants indicating that oxidative stress took place. We demonstrate that these events are accompanied by a significant increase in plastoquinone (PQ) level...

detection & classification of power quality (pq) disturbances are the most important problems in distribution systems. in this paper, a new approach for the detection and classification of single and combined pq disturbances is proposed which utilizes fuzzy logic and particle swarm optimization (pso) algorithms. in this approach, first suitable features of the waveform of pq disturbances ar...

bachground: paraquat (pq) intoxication manifests with pulmonary edema and fibrosis, heart failure, hepatic failure, and sometimes convulsions. in severe cases, the patients may die within the early hours. at best conditions, the conventional therapeutic methods can only save less than 50% of the victims of intentional pq intoxication. the aim of this study was to evaluate the outcome of new the...
