The aim of the present study was to compare the effects of hypericin and fluoxetine in the treatment of companion dogs with tail chasing in Ahvaz district. In the present survey, eighteen dogs with tail chasing were assigned into three equal groups for a three-year period. The dogs were randomly classified based on different treatment groups. During 15 weeks, dogs of group A were given 0.05 mg ...

zinc and iron nano-oxides (100 ppb) were promoted the hypericin and hyperforin production in hypericum perforatum cell suspension culture. high performance liquid chromatography method was used for detectection and identification of hypericin and hyperforin in h. perfuratum cell suspension cultures elicited with different concentrations of zinc and iron nano-oxide (0, 50, 100 and 150 ppb) after...

Next generation sequencing technology rapidly developed research applications in the field of plant functional genomics. Several Hypericum spp. with an aim to generate and enhance gene annotations especially for genes coding the enzymes supposedly included in biosynthesis of valuable bioactive compounds were analyzed. The first de novo transcriptome profiling of Hypericum annulatum Moris, H. to...

Hypericum triquetrifolium Turra. is a valuable medicinal plant owing to source of many bioactive compounds. Hypericin is one of the significant components among these compounds. The aim of this study was to develope an efficient method allowing to improve hypericin production from calli and cell suspension cultures of Hypericum triquetrifolium Turra. Callus formation was obtained from axenic le...

Hypericin and pseudohypericin were found in 27 of the 36 evaluated species from Hypericum L., belonging to 17 sections of the genus. Pseudohypericin is reported by us in 15 taxa for the first time. Most of the species contained both components and the amount of pseudohypericin usually exceeded that of hypericin. In H. hirsutum and H. empetrifolium only hypericin was found, whereas H. formosissi...

Glucose-dependent energy required for glioma metabolism depends on hexokinase, which is mainly bound to mitochondria. A decrease in intracellular pH leads to a release of hexokinase-binding, which in turn decreases glucose phosphorylation, ATP content, and cell proliferation. Thus, intracellular pH might be a target for therapy of gliomas, and a search for agents able to modulate intracellular ...

PURPOSE To produce proliferative vitreoretinopathy (PVR) in an animal ocular trauma model. To evaluate the inhibition of (PVR) emergence and progression by hypericin. METHODS Experimental Study. Nineteen pigmented male adult rabbits weighing between 2,000 and 3,000 grams were used in this study. All of them were submitted to trauma model with dispase and retinal diathermy to induce PVR membra...

Antibacterial treatments based on photosensitized production of reactive oxygen species is a promising approach to address local microbial infections. Given the small size of bacterial cells, identification of the sites of binding of the photosensitizing molecules is a difficult issue to address with conventional microscopy. We show that the excited state properties of the naturally occurring p...
