A method is presented for rapid extraction of the total plastoquinone (PQ) pool from Synechocystis sp. strain PCC 6803 cells that preserves the in vivo plastoquinol (PQH2) to -PQ ratio. Cells were rapidly transferred into ice-cold organic solvent for instantaneous extraction of the cellular PQ plus PQH2 content. After high-performance liquid chromatography fractionation of the organic phase ext...

DNA microarray technology was applied to gain insight into the role of the redox state of PQ pool as a retrograde factor mediating differential expression of Arabidopsis nuclear genes during the acclimation to changing irradiance. DNA microarray chips containing probes corresponding to 24 000 Arabidopsis nuclear genes were screened with cRNA samples prepared from leaves of plants exposed for 5 ...

paraquat is a commonly used herbicide in many countries which can lead to systematic poisoning on exposure, in this study, paraquat (pq)-induced changes in the expression of cyclooxygenase-2 (cox-2) along with biochemical and histopathological changes in the lungs, liver and kidneys were studied. twenty four male wistar rats (180-200 g) were exposed either against saline as control group or var...

BACKGROUND Results from trials of intermittent preventive treatment (IPT) in infants and children have shown that IPT provides significant protection against clinical malaria. Sulfadoxine-pyrimethamine (SP) given alone or in combination with other drugs has been used for most IPT programmes. However, SP resistance is increasing in many parts of Africa. Thus, we have investigated whether SP plus...

In this paper, we propose a memory-based Q-learning algorithm called predictive Q-routing (PQ-routing) for adaptive traac control. We attempt to address two problems encountered in Q-routing (Boyan & Littman, 1994), namely, the inability to ne-tune routing policies under low network load and the inability to learn new optimal policies under decreasing load conditions. Unlike other memory-based ...

Paraquat (PQ) is a widely used herbicide. However, a large number of cases of accidental or suicidal poisoning from PQ has been reported. Membrane damage induced by lipid peroxidation, inactivation of protein or damage to DNA by radical formation have been suggested as toxicity mechanisms of PQ. In the present work, the effects of atropine, propranolol, procainamide and dipyridamole on PQ-...

A bstract Parity solutions to the strong CP problem are a compelling alternative approaches based on Peccei-Quinn symmetry, particularly given expected violation of global symmetries in theory quantum gravity. The most natural these break parity at low scale, giving rise host experimentally accessible signals. We assess status simplest parity-based solution light LHC data and flavor constraints...

This paper describes role of UPQC as applied to a 3P4W system to improve PQ. The Forth wire of 3P4W system is developed by means of neutral of series transformer. Neutral current which flows through neutral terminal of transformer is removed with the help of 4 leg voltage source inverter (VSI) topology for shunt part. The series transformer neutral will have 0 potential in all conditions of ope...

In this paper, we propose a memory-based Q-Iearning algorithm called predictive Q-routing (PQ-routing) for adaptive traffic control. We attempt to address two problems encountered in Q-routing (Boyan & Littman, 1994), namely, the inability to fine-tune routing policies under low network load and the inability to learn new optimal policies under decreasing load conditions. Unlike other memory-ba...
