Preincubation of chloroplasts from pea leaves (Pisum sativum L. cv. Kelvedon) with 0.5 millimolar ferricyanide in the dark, caused a parallel inhibition of the rate of rise of the variable fluorescence and the rate of electron transport. Both reactions were inhibited to a similar extent by varying the time of preincubation, the concentration of ferricyanide during preincubation, and by raising ...

To understand the function of edges in perception of moving objects, we defined four questions to answer. Is the focus point in visual motion detection of a moving object: (1) the body or the edge of the object, (2) the leading edge or trailing edge of the object, (3) different in scotopic, mesopic and photopic luminance levels, or (4) different for colored objects? We measured the Optomotor Re...

Etravirine (ETR) is a novel non-nucleoside reverse transcriptase inhibitor (NNRTI) designed for binding to HIV reverse transcriptase in spite of most of the mutations which normally confer resistance to the other drugs of the same class. Evidences from clinical trials and post-marketing drug use provide guidance for the use of the drug in NNRTI-experienced patients. However, despite the raised ...

BACKGROUND Lifestyle changes and statins are the cornerstones in management of dyslipidaemia in patients with HIV infection. Replacement of an antiretroviral therapy (ART) component is a proposed therapeutic strategy to reduce cardiovascular risk. In dyslipidaemic patients with HIV infection, we assessed the efficacy of replacing boosted protease inhibitor (bPI) or efavirenz (EFV) by etravirine...

Owing amongst other to its high electron mobility, fullerene C70, has been widely used as an electron transporting layer in organic solar cells. In this research, we report the use of C70 thin films as electron transport layers of planar perovskite solar cells (PSCs) using a conventional device structure. The thickness of the C70 layer has been optimized to achieve the best efficiency of 12%. I...

The gene encoding human neuroblastoma apoptosis-related RNA binding protein (NAPOR) has rat and mouse homologues, Etr-r3 and mNapor, cloned recently by ourselves and others. Etr-r3/mNapor is transcribed in embryonic brain but its detailed expression patterns are unknown. It has been hypothesised that its expression coincides with the occurrence of programmed cell death, but existing expression ...

INTRODUCTION Switching therapy studies are usually designed as second-line antiretroviral treatment (ART) in patients without previous virologic failures. Combined ART (cART) with DRV/r and ETR has a good pharmacokinetic profile, high genetic barrier and has been proved as rescue therapy. The aim of our study was to analyze efficacy and safety of therapy with DRV/r plus ETR in treatment experie...

Isoprene emissions from the leaves of velvet bean (Mucuna pruriens L. var utilis) plants exhibited temperature response patterns that were dependent on the plant's growth temperature. Plants grown in a warm regimen (34/28 degrees C, day/night) exhibited a temperature optimum for emissions of 45 degrees C, whereas those grown in a cooler regimen (26/20 degrees C, day/night) exhibited an optimum ...

Optimal cell yield of Pseudomonas aeruginosa grown under denitrifying conditions was obtained with 100 mM nitrate as the terminal electron acceptor, irrespective of the medium used. Nitrite as the terminal electron acceptor supported poor denitrifying growth when concentrations of less than 15 mM, but not higher, were used, apparently owing to toxicity exerted by nitrite. Nitrite accumulated in...

Staphylococcus aureus formed an electron transport system when exponentially growing cells were aerated. Formation of the electron transport system occurred concomitantly with increases in the phospholipids and the carotenoids. The addition of piperonyl butoxide or benzo(a)pyrene at the onset of aeration (i) slowed the formation of the electron transport system, (ii) both inhibited cytochrome o...
