gross hematuria or macroscopic hematuria is a high risk urologic condition that might occur in different settings. in the case of continued gross hematuria, blood clot size may grow and lead to complete obstruction of urinary outflow. placement of three-way catheter, continuous bladder irrigation with normal saline, and cystoscopy are conventional treatments. here we introduce a case with urina...

Plant materials have been found useful in decontamination of water polluted with phenolic compounds. The detoxification effect is due to peroxidases contained in plant tissue. Enzyme mediated oxidative coupling of phenol is followed by precipitation of the formed polymer and its removal from the aqueous phase. A synthetic wastewater buffered at pH = 7.4 containing 0.9 mM phenol was treated in t...

Plant polyphenolic compounds have been recognised for their ability to prevent oxidation of susceptible substances by virtue of their electron donating property due to presence of large number of phenolic hydroxyl groups. The seed of Areca catechu contains higher proportions of polyphenolic compounds mainly tannins. Our objective involves quantification of tannins, determination of total phenol...

The olive oil extraction process yields liquid waste byproduct known as olive mill wastewater (OMW), which presents a major environmental problem, if not treated before dissipation. The large amounts of OMW generated, combined with its high polluting power as well as its high chemical oxygen demand (COD) concentrations, represent the main difficulties in finding a solution for the management of...

In concentration of hydrogen peroxide, first, the solution should be quite pure, and then, it concentrate with methods such as vacuum distillation and cooling crystallization, because impurities in the hydrogen peroxide solution in high concentrations are causing decomposition of this substance; that is very dangerous. The purpose of this article is separation of chromium and magne...

Extraction from edible plants is a highly important process that has various biological functions. To maximize activity, extraction methods should facilitate optimal of functional phytochemicals. In this study, the hydrothermal conditions Acer tegmentosum were determined using response surface methodology (RSM), and HepG2 cells treated with optimized extract hydrogen peroxide. central compositi...

In this work, we described a cost-effective and environmentally friendly technique for green synthesis of colloidal silver nanoparticles from aqueous extract of fresh leaves of Acacia melanoxylon and its application as a dopamine and hydrogen peroxide sensor. The prepared silver nanoparticles were characterized by UV-Visible absorption spectroscopy, X-ray diffraction (XRD), scanning electron mi...
