The effect of nano selenium foliar application on some secondary metabolites Hypericum perforatum L.

The effects of polysaccharide elicitors such as chitin, pectin, and dextran on the production of phenylpropanoids (phenolics and flavonoids) and naphtodianthrones (hypericin and pseudohypericin) in Hypericum perforatum shoot cultures were studied. Nonenzymatic antioxidant properties (NEAOP) and peroxidase (POD) activity were also observed in shoot extracts. The activities of phenylalanine ammon...

Amitriptyline hydrochloride is a highly permeable active pharmaceutical ingredient (API). The function of these drugs is to block the reuptake of the neurotransmitters, norepinephrine and serotonin in the central nervous system. The nano-sized Amitriptyline (AT) imprinted polymer particles were synthesized successfully. The nanoparticles were characterized by Fourier transform infrared spectros...

background and aims. incorporation of nano-particles to orthodontic bonding systems has been considered to prevent enamel demineralization around appliances. this study investigated cytotoxicity of transbond xt adhesive containing 1 wt% titanium dioxide (tio2) nano-particles. materials and methods. ten composite disks were prepared from each of the conventional and tio2-containg composites and ...

In the present study, the Tangrah region located in the vicinity of GolestanNational Park was selected for exploring the changes in the amount of the secondaryessential of hypericin in Hypericum perforatum in different highlands of the easternGolestan province. The aerial flowered parts of the herb were collected randomly and inthree replications from four altitudes of 300 m, 600 m, 900 m, and ...

Alzheimer's disease is multi-component neurodegenerative disorder. Oxidative stress disrupts regular functioning of metabolism in early-onset disease. It causes Tau phosphorylation, formation neurofibrillary tangle and neuron reduction. Due to intense binding phosphorylated amino acids aluminum, it induces self-assembly deposition high degree cytoskeletal proteins, such as microtubule neurofila...
