A novel azo-Schiff base ligand (L) was prepared by reacting 2-hydroxy-5-(pyridine-4-yldiazenyl) benzaldehyde with 1,2-phenylenediamine. Moreover, Silver nanoparticles (Ag-NPs) and Cadmium sulfide nanoparticles (CdS-NPs) were prepared by employing azo-Schiff base ligand (L) as capping and reducing agent. The solid-state fluorescence spectroscopy was used to investigate the interaction between L ...
Common kilka were chilled during 1, 2, 3, 4 and 5 days to determine the influence of such storage times of fish over the quality of the final canned product. For this propose, common factors for determination of fish quality (moisture, total lipid, free fatty acid, peroxide, thiobarbituric acid and fatty acid profile) were selected and compared with the formation of fluorescence compounds in fi...
In an orchard experiment, the effects of foliar application of kaolin, potassium, phosphorus and their different combinations were examined on photosynthesis parameter 8-years-old pistachio trees cv.Kalle-ghouchi in 2016. There were ten treatments, including two rate of P (1 and 2%), two rates of K (1.5 and 3%), kaolin 5%, kaolin 5%+ P 1%, kaolin 5%+P 2%, kaolin 5%+ K 1.5%, kaolin 5%+ K 3% and ...
introduction during the process photodynamic therapy (pdt), bleaching of photosensitizer induced by irradiation and generation of reactive oxygen species (ros) can provide some information concerning the efficiency of treatment. since gold nanoparticles (gnps) have been highlighted as efficient drug delivery systems, in this study, by utilizing gnps conjugated with 5 aminolevulinic acid (5-ala-...
امروزه pcr یک تکنولوژی کارآمد در بسیاری از زمینه ها از جمله پزشکی می باشد. وظیفه ی pcr کپی برداری از رشته ی dna مورد نظر است. pcr انواع گوناگونی دارد که در نوع مورد نظر این پژوهش، conventional pcr ، ابتدا نمونه ی dna به همراه آنزیم ها و سایر مواد لازم وارد محفظه ی مخصوصی که برای انجام پروسه های دمایی تعبیه شده است ، می شود و عملیات کپی شدن انجام می گیرد ؛ سپس با قرار دادن محتویات واکنش در ژل مخ...
This experiment was conducted to evaluate the effects of different concentrations of humic acid (0, 100, 500 and 1000 mg/L) and spraying times (1, 2, 3 and 4 weeks) on growth and yield of the ‘Hanza’ stock flower (Matthiola incana). The experiment was factorial, based on a completely randomized design, with 16 treatments and 7 replications in each treatment. Results of analysis of variance reve...
Background and Objectives: The inability of classic fluorescence-activated cell sorting to single cancer cell sorting is one of the most significant drawbacks of this method. The sorting of cancer cells in microdroplets significantly influences our ability to analyze cancer cell proteins. Material and Methods: We adapted a developed microfluidic device as a 3D in vitro model to sorted MCF-7 c...
glucose 6-phosphate dehydrogenase (g6pd) from streptomyces aureofaciens was purified and denatured in 6 m urea. denaturation led to complete dissociation of the enzyme into its inactive monomers, 98% loss of the enzyme activity, about 30% decrease in the protein fluorescence and a 10 nm red shift in the emission maximum. dilution of urea-denatured enzyme resulted in regaining of the enzyme acti...
bronchial asthma is the common chronic inflammatory disease and is characterized by chronic airway inflammation, airway remodeling, and airway hyperreactivity (ahr). aim of this study was to investigate the effects of mitochondrial atp-sensitive potassium channels (mitokatp) on the proliferation and secretion of human airway smooth muscle cells (hasmcs). hasmcs were treated with the serum from ...
background: this cross sectional comparative study was performed to compare the mean fluorescence intensity of cluster of differentiation 45 between healthy individuals and patients with acute lymphoblastic leukemia. patients and methods: thirty three healthy individuals (mean age 11 years) and 41 patients with b cell acute lymphoblastic leukemia (mean age 7 years) were enrolled in the study in...
