BACKGROUND Extensive drug resistance of Acinetobacter baumannii is a serious problem in the clinical setting. It is therefore important to find active antibiotic combinations that could be effective in the treatment of infections caused by this problematic 'superbug'. In this study, we analyzed the in vitro activities of three colistin-based combinations(More)
Beta cell mass and function are decreased to varying degrees in diabetes. Islet cell replacement or regenerative therapy may offer great therapeutic promise to people with diabetes. In addition to primary pancreatic β cells, recent studies on regeneration of functional insulin producing cells (IPCs) revealed that several alternative cell sources, including(More)
Mycotoxins are considered to be significant contaminants of food and animal feed. Zearalenone (ZEA) is a hepatotoxic mycotoxin with estrogenic and anabolic activity found in cereal grains worldwide. ZEA affects hematological and immunological parameters in humans and rodents. The compound can induce cell death, cause lipid peroxidation, inhibit protein and(More)
Trimethylamine N-oxide (TMAO) is an oxidation product of trimethylamine (TMA) and is present in many aquatic foods. Here, we investigated the effects of TMAO on glucose tolerance in high fat diet (HFD)-fed mice. Male C57BL/6 mice were randomly assigned to the control, high fat (HF), and TMAO groups. The HF group was fed a diet containing 25% fat, and the(More)
BACKGROUND TMS1/ASC is a bipartite protein comprising two protein-protein interactive domains: pyrin (PYD) and caspase recruitment domain (CARD). Proteins containing these domains play pivotal roles in regulating apoptosis and immune response pathways. The absence of TMS1/ASC expression in some tumors is because methylation of the TMS1/ASC gene contributes(More)
Patulin (PAT) is a mycotoxin produced by several Penicillium, Aspergillus and Byssochlamys species. Since PAT is a potent genotoxic compound, and PAT contamination is common in fruits and fruit products, the search for newer, better agents for protection against genotoxicity of PAT is required. In this study, the chemoprotective effect of 6-gingerol against(More)
In our previous study, we reported that sodium arsenite induced ROS-dependent apoptosis through lysosomal-mitochondrial pathway in pancreatic β-cells. Since the thioredoxin (Trx) system is the key antioxidant factor in mammalian cells, we investigate whether the inhibition of Trx system contributes to sodium arsenite-induced apoptosis in this study. After(More)
BACKGROUND MicroRNAs (miRNAs) are short, non-coding RNAs that negatively regulate target genes. A single nucleotide polymorphism (SNP) in a miRNA sequence may alter miRNA expression and/or maturation, which was proposed to associate with the development and progression of cancer. The rs895819 polymorphism, located in the terminal loop of pre-miR-27a, has(More)
Bisphenol A (BPA), an endocrine disruptor, is widely used to manufacture polycarbonate plastic and epoxy resins. Many studies have demonstrated that BPA can play a role in reproductive toxicity and affect the normal metabolic function. Recent research has shown that BPA can influence the function of pancreatic islets. In this study, our aim is to assess the(More)
The separation and removal of oil or organic pollutants from water is highly imperative. The oil phases in surfactant-free oil-in-water emulsions or in free oil/water mixtures can be smartly enriched and transported by using superhydrophobic/superoleophilic iron particles (SHIPs) under a magnetic field. For water-in-oil emulsion, SHIPs-based composite(More)
