the photocatalytic degradation of two anionic azo dyes acid red88 (ar 88) and acid orange 7 (ao7) was investigated in aqueous solution using a tio2-containing hydrogel and uv light. the ph-sensitive hydrogel poly (styrene-alt-maleic anhydride) (psma), was synthesized and crosslinked in the presence of melamine and tio2 nanoparticles which results in entrapment of tio 2 into the melamine-grafted...

patients with acute myeloblastic leukemia (aml) with monosomy 7 are a group of patients with refractory aml who have a very poor prognosis. therefore, rationally designed new therapies, including metronomic chemotherapy regimen with histidine deacetylase inhibitors (valporic acid, atra) are being investigated as potential treatments for the population of refractory cases of aml. herein, we repo...

the biosynthetic pathways of saturated and unsaturated fatty acids consist of many steps controlled by various enzymes. one of the methods for improving oil quality is to change the fatty acid profile through genetic manipulation which requires isolation and characterization of the genes and other cis-acting elements, such as the promoter, involved in fatty acid biosynthesis. b-ketoacyl-coa syn...

an experiment was conducted to reevaluate the digestible lysine requirement of arian male broilers by comparing the performance of chicks fed different levels of cottonseed meal (csm) on a total amino acid (aa) versus a digestible aa basis. four hundred and thirty two (432) arian male broiler chicks were allotted to 18 treatments with four repli-cates of six chicks each in a completely randomiz...

gerbera one of 10 important cut flowers in the world and iran. one of the most problems is low-life after harvest and neck bending. producers want to increase longevity of these flowers with using chemical solutions. with the aim of achieving the best chemical treatments to increase flower vase life gerbera goodtimming, nano silver (5 mg l-1), humic acid (50 mg l-1), gibberellic acid (2.5 mg l-...

background: endometriosis, a common chronic inflammatory disorder, is defined by the atypical growth of endometrium- like tissue outside of the uterus. secretory phospholipase a2 group iia (spla2-iia) and fatty acid binding protein4 (fabp4) play several important roles in the inflammatory diseases. objective: due to reported potential anti-inflammatory effects of ω-3 and ω-6 fatty acids, the pu...

objective: this study aimed to assess the destructive effects of citric acid, lactic acid and acetic acid produced from the fermentation of foods on primary teeth enamel.   methods: this in vitro, experimental study was conducted on 24 sound primary teeth. the teeth were polished with a fine abrasive paper under running water. tooth pieces measuring 3 × 4 × 3mm were cut out of the teeth and sto...
