Graphite carbon nitride-modified screen-printed electrode as a highly sensitive and selective sensor for detection of amaranth.

This work presented a particular electrochemical sensor for analysis of amaranth, an azo toxic dye. A graphite nitride carbon (g-CN) was used to modify an electro-treated screen-printed electrode (g-CN/SPE) for electroanalysis of amaranth. Physicochemical characteristics and analytical performance of g-CN/SPE were investigated by relevant equipment.

Is opium use associated with an increased risk of lung cancer? A case-control study.

Background: In recent years, lung cancer (LC) incidence has increased in Iran. The use of opium and its derivatives (O&D) has increased as well. This study aimed to investigate the association between the use of O&D and LC incidence.

Opium Use and Head and Neck Cancers: A Matched Case-Control Study in Iran.

Background: Head and Neck (H and N) cancers include malignant tumors of the nasal cavity, pharynx, paranasal sinuses, oral cavity, larynx and salivary glands. Opium use might be related to these cancers. The aim of this study was to investigate the relation between Opium and its Derivatives (O and D) use and the incidence of H and N cancers.

Effect of trifluoperazine on carrageenan-induced acute inflammation in intact and adrenalectomized rats.

The aim of present study was to investigate the effect of trifluoperazine (TFP) on carrageenan-induced rat's paw edema in intact and adrenalectomized (ADX). TFP (0.2 and 8 mg/kg) were given intraperitoneally just before the intraplantar injection of 0.
