The present paper analyses the results of competitive blood-cell repopulation experiments in which Cx43-WT (connexin 43 wild-type) host mice, whose own HSCs (haemopoietic stem cells) were deleted, were grafted with fetal liver cells: 50% Gpi-1a (glucose phosphate isomerase-1a)/Cx43-WT cells competing with 50% Gpi-1b/Cx43-WT, 50% Gpi-1b/Cx43-HZ (heterozygous) or 50% Gpi-1b/Cx43-KO (knock-out) ce...

It is known to be much slower folding than similarly sized proteins, despite having a low contact order. Proteins are sufficiently well d...

results the predominant genotype among bahraini patients was type 1 (36.71%), followed by genotypes 3 and 4 (15.6% each) and the lowest frequency was found for genotype 2 (3.9%). among genotype 1, subtype 1b had the highest frequency (21.09%), followed by subtype 1a (14.06%). among genotype 3, subtype 3a had the highest frequency (11.72%), while among genotype 4, most of subtypes were undetermi...

Uncoupling protein (UCP) is expressed only in brown adipocytes and is responsible for the unique thermogenic properties of this cell type. The novel brown preadipocyte cell line, HIB-1B, expresses UCP in a strictly differentiation-dependent manner. Transgenic mice studies have shown that a region from kb -2.8 to -1.0 of the marine UCP gene is required for brown adipocyte-specific expression. Su...

The molecular mechanisms responsible for increasing iron and neurodegeneration in brain ischemia are an interesting area of research which could open new therapeutic approaches. Previous evidence has shown that activation of nuclear factor kappa B (NF-κB) through RelA acetylation on Lys310 is the prerequisite for p50/RelA-mediated apoptosis in cellular and animal models of brain ischemia. We hy...

The postulated transition of Bis-Maltolato-OxoVanadium(IV) (BMOV) from its inactive trans- into its cis-aquo-BMOV isomeric form in solution was simulated by means of computational molecular modeling. The rotational barrier was calculated with DFT - B3LYP under a stepwise optimization protocol with STO-3G, 3-21G, 3-21G*, and 6-31G ab initio basis sets. Our computed results are consistent with re...

A heteroduplex tracking assay (HTA) was developed for genetic analyses of the hepatitis C virus (HCV) using single-stranded probes from the core (C)/E1 region. Nucleotide sequencing of reverse transcriptase (RT)-PCR products from 15 Italian dialysis patients confirmed the specificity and accuracy of the HTA genotyping method, which identified 5 of 15 (33.3%) 1b, 7 of 15 (46.7%) 3a, and 3 of 15 ...

CONTEXT Serotonergic dysfunction is implicated in the pathogenesis of posttraumatic stress disorder (PTSD), and recent animal models suggest that disturbances in serotonin type 1B receptor function, in particular, may contribute to chronic anxiety. However, the specific role of the serotonin type 1B receptor has not been studied in patients with PTSD. OBJECTIVE To investigate in vivo serotoni...

The objective of the present study was to examine the cassette dosing method in determination of brain-to-plasma concentration ratio (area under the concentration-time profiles for plasma/area under the concentration-time profiles for brain, K(p)). Eleven model compounds, amprenavir, citalopram, digoxin, elacridar, imatinib, (3S,6S,12aS)-1,2,3,4,6,7,12,12a-octahydro-9-methoxy-6-(2-methylpropyl)...

OBJECTIVE To assess efficacy, safety, and tolerability of every-other-day interferon beta-1b treatment in patients with a first clinical event suggestive of multiple sclerosis (MS) (clinically isolated syndrome). METHODS We conducted a multicenter, randomized, double-blind, placebo-controlled trial. Patients with a first clinical demyelinating event and at least two clinically silent brain MR...
