A simple and sensitive indirect spectrophotometric method for the assay of meloxicam (MX), tenoxicam (TX) and piroxicam (PX) in pure and in pharmaceutical formulations by flow injection analysis (FIA) has been proposed. The method is based on the oxidation of these drugs by a known excess of N-bromosuccinimide (NBS) in an acidic medium, followed by a reaction of excess oxidant with chloranilic ...
The indirect gas-diffusion flow injection method (FI) was modified, optimized and successfully applied to bromide determination in various samples such as active substances, drugs, organic substances and water samples. The method is based on the oxidation of bromide to bromine in acidic medium, which diffuses through PTFe membrane into the acceptor flow that carried bromine to the amperometric ...
Determination of sulphite in wine by flow injection analysis with indirect electrochemical detection
A flow-injection method has been developed for the determination of total sulphite in wine samples. After hydrolysis of bound sulphite, sulphur dioxide is separated from the matrix by means of an in-line gas diffusion module. For detection indirect amperometry is used, with iodine as oxidizing reagent. The iodine can be generated in-line by merging and mixing iodate and iodide solutions, or alt...
This paper presents a model for generating a MAC tag with a stream cipher using the input message indirectly. Several recent proposals represent instances of this model with slightly different options. We investigate the security of this model for different options, and identify cases which permit forgery attacks. Based on this, we present a new forgery attack on version 1.4 of 128-EIA3. Design...
toury (1978:200) believes that translation is a kind of activity which inevitably involves at least two languages and two cultural traditions. being polite while asking for something takes place differently in different cultures and languages, therefore various strategies may be applied for making requests and also translation of them in order not to disturb or threaten the face or better to sa...
Separate concurrent injection of organic gold compounds and antigen into mice resulted in immunoenhancement that could be measured by direct and indirect plaque-forming cells, rosette-forming cells, and serum antibody assays. Kinetics of the immune response showed variable effects through day 9 of the experiment. Studies with British anti-lewisite, a gold antagonist, showed that the gold must s...
We injected an intravitreal dexamethasone implant in two eyes of 2 pediatric patients with Coats' disease in addition to other treatment modalities, such as intravitreal ranibizumab injection and indirect laser photocoagulation. In both eyes, intraocular pressure moderately rose in a temporary fashion. The dexamethasone implant seems to be a valuable addition to the armamentarium of treatment o...
purpose: to evaluate the effects of intravitreal and intracameral injection of bevacizumab in patients with neovascular glaucoma (nvg). methods: this interventional case series was conducted on 40 eyes of 40 patients with neovascular glaucoma. data included the extent of iris (nvi) and angle neovascularization (nva), peripheral anterior synechia (pas), and intraocular pressure (iop). followin...
The objective of this study was to contribute to investigate the efficacy of letrozole, a potent non-steroidal aromatase inhibitor, on serum sex steroid levels and oocyte growth in rainbow trout females. Serum steroid levels were measured using an indirect enzyme-linked immunosorbent assay (ELISA) before and 22 days after an initial injection with 1, 2.5 mg kg-1 and subsequent weekly injection ...
