1,3-Butadiene is a carcinogen in rodents, but its potential carcinogenicity to humans remains controversial. Numerous studies have shown that butadiene and its metabolites cause sister chromatid exchanges in vitro and in vivo. To test for other types of genotoxicity, the micronucleus assay and fluorescence in situ hybridization (FISH) have been used to detect chromosome damage in human lymphocy...

OBJECTIVE We conducted a meta-analysis to evaluate the efficacy and toxicity of DEB-TACE in the treatment of patients with intermediate-stage HCC. METHODS Studies published in PubMed, Embase and Web of Science, were systematically reviewed to identify those that assessed the efficacy and toxicity of DEB-TACE in the treatment of patients with HCC. Hazard ratio, risk ratioand 95% confidence int...

BACKGROUND/AIM Fanconi anemia (FA) is a rare hereditary disease in a heterogeneous group of syndromes, so-called chromosome breakage disorders. Specific hypersensitivity of its cells to chemical agents, such as diepoxybutane (DEB), was used as a part of screening among patients with clinical suspicion of FA. The aim of this study was to determine chromosomal instability in patients with FA symp...

1,3-Butadiene (BD) is an important industrial chemical that is classified as a human carcinogen. BD carcinogenicity has been attributed to its metabolism to several reactive epoxide metabolites and formation of the highly mutagenic 1,2:3,4-diepoxybutane (DEB) has been hypothesized to drive mutagenesis and carcinogenesis at exposures experienced in humans. We report herein the formation of DEB-s...

The single and combined effects of carbamazepine and vinpocetine on the release of the excitatory amino acid neurotransmitter glutamate, on the rise in internal Na+ (Na(i), as determined with SBFI), and on the rise in internal Ca2+ (Ca(i), as determined with fura-2) induced by an increased permeability of presynaptic Na+ channels, with veratridine, or by an increased permeability of presynaptic...

some important compatibility that occur with exercise is increase of the capillary density or angiogenesis. vascular endothelial growth factor (vegf) have mitogen role for endothelial cells and consider an important intermediary angiogenesis process. the purpose of this study was comparing the effect of two type of physical activity on response of serum vegf-a in non-athlete men. for this aim 1...

BACKGROUND The place of drug-eluting balloons (DEB) in the treatment of in-stent restenosis (ISR) is not well-defined, particularly in a population of all-comers with acute coronary syndromes (ACS). OBJECTIVE Compare the clinical outcomes of DEB with second-generation drug-eluting stents (DES) for the treatment of ISR in a real-world population with a high proportion of ACS. METHODS A retro...

Renal mass and glomerular filtration rate (GFR) were reduced from normal to approximately 15% of normal in two groups of dogs. One group received a constant salt intake (CSI) throughout the study. The second group was subjected to "proportional reduction" of sodium intake (PRS), a dietary regimen which involved the reduction of sodium intake in exact proportion to the decrement in GFR. In the C...

Regulation of the cytosolic free Ca2+ concentration ([Ca2+]cyt) by an Na/Ca exchanger was studied in primary cultured rat cortical astrocytes. [Ca2+]cyt was measured by digital imaging in cells loaded with fura-2. The resting [Ca2+]cyt, approximately 150 nM, was only slightly increased by reducing the extracellular Na+ concentration ([Na+]o) to 6.2 mM, or by treating the cells with ouabain for ...
