Introduction: Adsorption capacity of activated charcoal to paracetamol was determined at simulated gastric environment, pH 3.4 and simulated intestinal environment pH 7.2. Three formulations of activated charcoal; powder, capsule and suspension were tested. Paracetamol was derived from tablet to simulate in vivo intoxication conditions. Methods: Activated charcoal and paracetamol were mixed at ...

UNLABELLED PREMISE OF THE STUDY Charcoal particles preserved in sediments are used as indicators of paleowildfire. Most research focuses on abundance as an indicator of fire frequency, but charcoals also convey information about the vegetation from which they are derived. One potential source of information is their morphology, which is influenced by the parent material, the nature of the fi...

OBJECTIVES Following the first case in Hong Kong in 1998, the method of committing suicide by charcoal burning has spread to other communities. This aim of this study was to examine the impact of charcoal burning suicides on both overall suicide rates and older-method suicide rates in Hong Kong and urban Taiwan. DESIGN Trend analysis of the overall and method-specific suicide rates between 19...

By lumping together charcoal and firewood consumption to determine the threats to forests from widespread use of woodfuel energy in sub-Sahara African, studies have greatly underestimated the individual impact of charcoal. Where high consumption levels are coupled with poor forest management and negligible regulation of the charcoal trade, the threat of an impending crisis caused by charcoal al...

Neutralization represents an important goal in toxicology, reducing exposure to poison being crucial in any management plan of any intoxication. Controversial data actually exists in the literature regarding activated charcoal capacity to bind organophosphates. To determine and compare organophosphate binding capabilities for different hydrophobic substances, considered to have neutralising pro...

This study experimentally analyzed the carbon dioxide adsorption capacity of Moso-bamboo- (Phyllostachys edulis-) based porous charcoal. The porous charcoal was prepared at various carbonization temperatures and ground into powders with 60, 100, and 170 meshes, respectively. In order to understand the adsorption characteristics of porous charcoal, its fundamental properties, namely, charcoal yi...

The use of Stainer-Scholte broth supplemented with (2,6-O-dimethyl)beta-cyclodextrin (heptakis) for the isolation of Bordetella pertussis from clinical specimens was evaluated with 3,632 nasal swabs from children and adults with suspected whooping cough or from their family contacts. The liquid enrichment medium was subcultured on charcoal agar with 10% defibrinated horse blood. Charcoal agar a...

PURPOSE A charcoal filter attached within the anesthetic circuit has been shown to efficiently adsorb halothane or isoflurane, thus hastening anesthetic recovery in low or minimal flow system. This study was intended to demonstrate whether the charcoal filter enhances the recovery time from sevoflurane anesthesia using a semi-closed circuit system. MATERIALS AND METHODS Thirty healthy patient...

Over the past several decades, high-resolution sediment–charcoal records have been increasingly used to reconstruct local fire history. Data analysis methods usually involve a decomposition that detrends a charcoal series and then applies a threshold value to isolate individual peaks, which are interpreted as fire episodes. Despite the proliferation of these studies, methods have evolved largel...
