Recent studies have shown that intracellular Ca2+ handling is abnormal in the myocardium of patients with end-stage heart failure. Muscles from the failing hearts showed a prolonged Ca2+ transient and a diminished capacity to restore a low resting Ca2+ level during diastole. Accordingly, we examined whether this defect in Ca2+ transport function is due to(More)
BACKGROUND Neural endocannabinoid function appears to be involved in schizophrenia. Two endocannabinoid receptors, CB1 and CB2, are found in the brain and elsewhere in the body. We investigated roles of CB2 in schizophrenia. MATERIALS AND METHODS An association study was performed between tag single nucleotide polymorphisms (SNPs) in the CNR2 gene(More)
CARP, a cardiac doxorubicin (adriamycin)-responsive protein, has been identified as a nuclear protein whose expression is downregulated in response to doxorubicin. In the present study, we tested the hypothesis that CARP serves as a reliable genetic marker of cardiac hypertrophy in vivo and in vitro. CARP expression was markedly increased in 3 distinct(More)
Although the correct folding of green fluorescent protein (GFP) is required for formation of the chromophore, it is known that wild-type GFP cannot mature efficiently in vivo in Escherichia coli at 37 degrees C or higher temperatures that the jellyfish in the Pacific Northwest have never experienced. Recently, by random mutagenesis by the polymerase chain(More)
In the present study, we demonstrated the constitutive expression of diffusible axon guidance molecules such as neurotrophins, semaphorin-III, netrin-1, and netrin-2-like protein, which are known to function as a chemoattractant and/or chemorepellent for growing nerve fibers, in human osteoblastic and osteoclastic cells. The findings, obtained by RT-PCR,(More)
BACKGROUND Sialyltransferase 8B (SIAT8B) and 8D (SIAT8D) are two polysialyltransferases that catalyze the transfer of polysialic acid (PSA) to the neural cell adhesion molecule 1 (NCAM1). PSA modification of NCAM1 plays an important role in neurodevelopment of the brain and disruption of this process is postulated as an etiologic factor in psychiatric(More)
We recently reported a new rapid screening method for glucose-6-phosphate dehydrogenase (G6PD) deficiency. This method incorporates a new formazan substrate (WST-8) and is capable of detecting heterozygous females both qualitatively and quantitatively. Here, we report its evaluation during field surveys at three malaria centres and in malaria-endemic(More)
BACKGROUND Contrast-enhanced fast magnetic resonance (MR) images of acute, reperfused human infarcts demonstrate regions of hypoenhancement and hyperenhancement. The relations between the spatial extent and time course of these enhancement patterns to myocardial risk, infarct, and no-reflow regions have not been well characterized. METHODS AND RESULTS The(More)
A consistent rat model for the study of the consequences of congophilic and fibrillar A beta-amyloid in brain has been developed. One hundred percent of animals receiving infusions of synthetic beta-amyloid protein (A beta 1-40) plus a specific heparan sulfate proteoglycan (HSPG) for 1 week or 7 weeks (following 2 week infusions) demonstrated Congo red and(More)
The effects of sodium saccharin and caffeine on urinary bladder carcinogenesis in Wistar strain rats treated with N-butyl-N-(4-hydroxybutyl)nitrosamine (BBN) were studied. Animals were given 0.01% BBN as an initiator for 4 weeks and then sodium saccharin and/or caffeine as promoters for 32 weeks (Experiment I), or were treated simultaneously with 0.001%(More)
