We stably transfected human kidney embryonic 293 cells with the rat neuronal nicotinic acetylcholine receptor (nAChR) alpha3 and beta4 subunit genes. This new cell line, KXalpha3 beta4R2, expresses a high level of the alpha3/beta4 receptor subtype, which binds (+/-)- [3H]epibatidine with a Kd value of 304+/-16 pM and a Bmax value of 8942 +/- 115 fmol/mg(More)
This does not exclude the possibility, that larger structural fragments (such as tetra-mers and pentamers) can also contribute to the low-frequency vibrational spectrum around the boson peak. On the basis of these results, the following model of the glass transition of glycerol can be proposed. At temperatures far above Tg (186 K), the lifetime of the MRO(More)
In the present study, we examined the direct cytotoxic effects of cocaine on fetal cardiac myocytes. Cocaine treatment of cultured fetal rat (21 days) myocardial cells (FRMCs) induced a time- and concentration-dependent increase in apoptotic cells in FRMCs. Cocaine induced surface exposure of phosphatidylserine in FRMCs at 12-h treatment and increased(More)
Corn and peanut oil (total, 253 samples) were collected from 32 households in Fushui county of the Guangxi autonomous region of the People's Republic of China, where high liver cancer incidence has been reported, every day over a period of 1 week and analyzed for aflatoxin B1 (AFB). A total of 252 urine samples were collected simultaneously from the(More)
Hypothermia is known to protect myocardium during ischemia, but its role in induction of a protective stress response before ischemia has not been evaluated. As cold incites stress responses in other tissues, including heat shock protein induction and signaling mitochondrial biogenesis, we postulated that hypothermia in perfused hearts would produce similar(More)
The differences on DNA yield and purity of three different DNA extraction protocols were compared with regard to the use for PCR and other molecular analyses. Total DNA was extracted from compost by the three protocols, and then was purified by spin-bind cartridges after being precipitated by PEG8000. The detection performed on a nucleic acid and protein(More)
The present study examines the effect of acetylcholine (ACh), muscarinic acetylcholine receptors (mAChRs) agonist pilocarpine and mAChRs antagonist atropine on the pain-evoked response of pain-excited neurons (PEN) and pain-inhibited neurons (PIN) in the hippocampal CA1 of rats. The trains of electric impulses applied to the sciatic nerve were used as(More)
The F1-ATPase is a multimeric enzyme (alpha3 beta3 gamma delta epsilon) primarily responsible for the synthesis of ATP under aerobic conditions. The entire coding region of each of the genes was deleted separately in yeast, providing five null mutant strains. Strains with a deletion in the genes encoding alpha-, beta-, gamma- or delta-subunits were unable(More)
BACKGROUND Schizophrenia (SCZ) and psychotic bipolar disorder (PBD) share considerable overlap in clinical features, genetic risk factors and co-occurrence among relatives. The common and unique functional cerebral deficits in these disorders, and in unaffected relatives, remain to be identified. METHOD A total of 59 healthy controls, 37 SCZ and 57 PBD(More)
