Chlorpheniramine sensitive electrode

Pharmacodynamic aspects of chlorpheniramine-induced bronchodilatation.

In 12 asthmatic (A) and ten normal (N) subjects, we measured the effect of inhaled saline solution, acetylcholine, histamine (H), and chlorpheniramine (CP) on specific airway conductance and forced exploratory flows. We found that CP dilated the bronchi in six asthmatic patients and one normal subject by acting on bronchial H1 receptor. This action is also modulated by the abnormal functions of...

DNA-chlorpheniramine interaction studied by spectroscopic techniques.

It was previously studied that the antihistaminic chlorpheniramine elicits a biphasic response on cell growth and regulates polyamine metabolism, as described for polyamines. In part, polyamine effects on macromolecular synthesis and cell growth are attributed to nucleic acid:polyamine interactions. In this work, we have tested the hypothesis of a DNA:chlorpheniramine interaction, using fluorom...

Sensitive Voltammetric Determination of Acetaminophen at Poly(4-vinyl pyridine)/Graphene Composite Modified Electrode

This study demonstrates the use of a selective and sensitive voltammetric sensor for determination of acetaminophen (AC). This was  performed by modifying a glassy carbon electrode with composite film of poly(4-vinylpyridine) and graphene sheet (P4VP/GR-GCE). The redox peak currents of AC increased significantly at P4VP/GR-GCE. The result was achieved by the synergistic effect of combined elect...

A Highly Sensitive Glucose Electrode Using Glucose Oxidase Collagen Film

Highly Sensitive Capacitive Gas Sensing at Ionic Liquid-Electrode Interfaces.

We have developed an ultrasensitive gas-detection method based on the measurement of a differential capacitance of electrified ionic liquid (IL) electrode interfaces in the presence and absence of adsorbed gas molecules. The observed change of differential capacitance has a local maximum at a certain potential that is unique for each type of gas, and its amplitude is related to the concentratio...
