Addictive drugs, such as opioids, ethanol, cocaine, amphetamine, and phencyclidine (PCP), affect many functions of the nervous system and peripheral organs, resulting in severe health problems. G protein-activated inwardly rectifying K(+) (GIRK, Kir3) channels play an important role in regulating neuronal excitability through activation of various Gi/o protein-coupled receptors including opioid...
Pneumocystis jiroveci pneumonia (PCP) has long been recognized as a cause of mortality in immuno-compromised populations, including those with advanced lung cancer. Although Pneumocystis colonization has only recently been described due to the development of more sensitive molecular techniques, including polymerase chain reaction (PCR), it is unknown whether Pneumocystis colonization leads to t...
Recombinant clones of the carboxyl terminus of the major surface glycoprotein (MsgC) of Pneumocystis jirovecii are useful for analyzing serologic responses in humans. However, there is no standardized set of antigens in general use, which could lead to conflicting results. We have previously shown that human immunodeficiency virus type 1 (HIV-1)-infected patients with prior Pneumocystis pneumon...
The effects of phencyclidine (PCP) were studied on the electrogenic and chemosensitive properties of the neuromuscular junction of skeletal muscle as well as on the binding sites on the acetylcholine (AcCho) receptor and its ionic channel in the electric organ membranes of the electric ray. The directly elicited muscle twitch was markedly potentiated by prolonging the falling phase of the muscl...
Much of our understanding of the genetic mechanisms that control planar cell polarity (PCP) in epithelia has derived from studies of the formation of polarized cell hairs during Drosophila wing development. The correct localization of an F-actin prehair to the distal vertex of the pupal wing cell has been shown to be dependent upon the polarized subcellular localization of Frizzled and other co...
This study explored biostimulation mechanisms with an electron donor and a shuttle for accelerating pentachlorophenol (PCP) transformation in iron-rich soils. The results indicated that indigenous microbial communities are important for PCP transformation in soils. Biostimulation of indigenous microbial communities by the addition of lactate and anthraquinone-2,6-disulfonate (AQDS) led to the e...
Pentachlorophenol (PCP) was widely used as a wood preservative in Germany until 1989, when it was prohibited by law. Within a cross-sectional study we investigated the internal PCP exposure of painters and bricklayers between one year and four years after the ban. PCP was analysed in post-shift urine samples of 189 painters and 148 bricklayers by gas chromatography and electron capture detectio...
Using western blottings, microdialysis, and functional assays we tested the hypothesis that phencyclidine (PCP) modifies the expression and function of glutamate (Glu) transporters in the rat frontal cortex. Western blotting studies revealed that administration of PCP (10 mg/kg/day; 7 days) increased significantly the expression of the astrocytic Glu transporter GLT-1/EAAT2. Functional studies ...
Pentachlorophenol (PCP) is widely used as a biocide, although, its usage is limited to restricted regions in Japan because of its strong toxicity to fishes. With regard to the biochemical aspects of PCP toxicity, Weinbach1) found that PCP inhibited oxidative phosphorylation in vitro and postulated that the inhibition was at least partly responsible for the toxic effects of PCP. Since then, bioc...
Patients with inflammatory bowel disease (IBD) are subject to a spectrum of immunosuppressive agents including corticosteroids, immunomodulators, and biological therapies. Despite the benefits of these therapies and their ability to induce remission, they increase the risk of infectious complications with various organisms including Pneumocystis jiroveci pneumonia (PCP), which is associated wit...
