Two experiments were performed to screen bacilli isolated from quails for their aflatoxin removal potential and to assess the efficiency of their amelioration of experimental aflatoxicosis. Nonhemolytic bacilli were selected for in vitro aflatoxin B1 (AFB1) removal and conventional probiotic tests. The isolate with the highest scores was selected for assessment in field experiments and was iden...

OBJECTIVES AMP-activated protein kinase (AMPK) is suggested to exert cytoprotective and anti-inflammatory effects in endothelial cells, but the precise mechanisms are not fully understood. It has been reported that pharmacological activation of AMPK induces endothelial heme oxygenase-1 (HO-1) expression. β-Lapachone (BL), a well-known substrate of NAD(P)H quinone oxidoreductase (NQO1), stimul...

The neuroepithelial basal lamina (BL) appears to be crucial in controlling cell-cell interactions during the early histogenesis of the nervous system. In this investigation we examined the changes in the BL in a neurological mutant of the rat previously characterized as having BL anomalies which progress to aqueductal stenosis and prenatal hydrocephalus. Embryos were obtained from matings of ra...

Recently, we have developed novel polyethylene glycol modified liposomes (bubble liposomes; BL) entrapping an ultrasound (US) imaging gas, which can work as a gene delivery tool with US exposure. In this study, we investigated the usefulness of US-mediated gene transfer systems with BL into synoviocytes in vitro and joint synovium in vivo. Highly efficient gene transfer could be achieved in the...

BACKGROUND We aimed to develop and evaluate outcomes of a blended learning (BL) program for educating nursing and midwifery students of Tehran university of medical sciences (Tehran, Iran). MATERIALS AND METHODS This was a participatory action research project. After designing BL website, providing technological infrastructures, and holding preparatory workshops, 22 blended courses were desig...

It was reported earlier that 7B-1 mutant in tomato (Solanum lycopersicum L.), an ABA overproducer, is defective in blue light (BL) signaling leading to BL-specific resistance to abiotic and biotic stresses. In this work, we examine responses of stomata to blue, red and white lights, fusicoccin, anion channel blockers (anthracene-9-carboxylic acid; 9-AC and niflumic acid; NIF) and ABA. Our resul...

We previously developed novel liposomal nanobubbles (Bubble liposomes [BL]) that oscillate and collapse in an ultrasound field, generating heat and shock waves. We aimed to investigate the feasibility of cancer therapy using the combination of BL and ultrasound. In addition, we investigated the anti-tumor mechanism of this cancer therapy. Colon-26 cells were inoculated into the flank of BALB/c ...

The fact that the p16/INK4a and p15/INK4b genes are frequently inactivated in human malignancies and that p16/INK4a null mice spontaneously develop B-cell lymphomas prompted us to examine the status of both genes in Burkitt's Lymphoma (BL). We found a low frequency of p16/INK4a and p15/INK4b deletions and mutations in BL cell lines and biopsies. However, p16/INK4a exon 1 was methylated in 17 ou...

The transepithelial transport of ascorbate across the isolated rabbit ciliary epithelium (CE) was investigated. Unidirectional 14C-ascorbate fluxes were measured in the presence of equal concentrations of ascorbate on both sides of the tissue within the range of 0.025 to 1 mM. The blood to aqueous (Bl----Aq) flux increased from 6 to 95 nmoles/hr and showed nonlinearity and saturation. The aqueo...

treated × 6 months) were included. Whole blood VL was determined by real-time PCR at a central laboratory before therapy (baseline, BL) and periodically for 6 months. Results. In subjects treated for 6 months, increases in BL VL correlated with decreased probability of better hearing outcomes at 12 months (Figure 1), but clinically meaningful VL thresholds that predict SNHL were not identified ...
