The purpose of the present paper is to present some simplifying modifications of Pfltiger’s method (1) for the estimation of glycogen, that render it available for small amounts of tissue. The suggested modifications involve (a) shortening of the time necessary to hydrolyze the tissue with strong alkali, (b) facilitation of the separation of the glycogen by precipitating it in the presence of c...

Fire suppression and changing climate have resulted in increased large wildfire frequency and severity in the western United States, causing carbon cycle impacts. Forest thinning and prescribed burning reduce high-severity fire risk, but require removal of biomass and emissions of carbon from burning. During each fire a fraction of the burning vegetation and soil organic matter is converted int...

actual amount of MTX bound to DHFR at a given ligand concentration. Exposure to charcoal for 1 min allowed complete adsorption of all unbound ligand while maintaining the maximum concentration of. ternary complex, as the complex was relatively stable for 3 min following charcoal exposure (Fig. 2), We applied this new technique to a study of MTX binding constants (Kv) to DHFR purified from both ...

We compared conventional charcoal separation of antibody-bound and free antigen with a novel method involving magnetizable particles containing charcoal. The magnetizable charcoal separation method was as effective as the conventional method for a wide range of radioimmunoassays, including those for several steroids and small polypeptide hormones. In a detailed comparison of conventional vs. ma...

The objective of this study was to investigate the effects of manufacturing conditions on the adsorption capacity of heavy metal ions by Makino bamboo charcoal. Results show that the specific surface area and iodine number of bamboo charcoal activated at 900 degrees C were larger than those of bamboo charcoal activated at 800 degrees C. The specific surface area of bamboo charcoal activated at ...

a total of 280 unsexed broiler chicks, 21 days-old and weighing 580 g on average were randomly distributed into 28 experimental units of 10 birds each. seven experimental diets containing respectively 0% (t0 control), 20% raw cowpeas (t1), 20% raw cowpeas + 0.2% of canarium charcoal (t2), 20% raw cowpeas + 0.2% maize cob charcoal (t3), 20% cooked cowpeas (t4), 20% cooked cowpeas + 0.2% canarium...

Abstract In this paper, the problems which can occur when wastewater is discharged into surface water bodies are considered. Modern methods of treatment presented: mechanical, chemical, biological, physical-and-chemical, and combined methods. Examples green infrastructure technologies with biofiltration function given, easy to use effective in both urban production runoffs, principles landscape...

A case of a patient who developed an intestinal perforation secondary to a charcoal stercolith is reviewed. The case involves a young female on methadone maintenance who received multiple-dose charcoal therapy for an amitriptyline ingestion. Peritoneal signs developed several days after admission, and an exploratory laparotomy was done. A perforation measuring 4 cm in diameter was found in the ...

To evaluate the effect of activated charcoal on aminoglycoside pharmacokinetics, six healthy volunteers received tobramycin intravenously with and without multiple oral doses of activated charcoal. Activated charcoal did not have a statistically significant effect on any pharmacokinetic parameter. We conclude that activated charcoal does not enhance tobramycin clearance in subjects with normal ...

Charcoal is the main cooking fuel for urban populations in many African countries. Urbanization and population growth are driving an increase in demand for charcoal, whilst deforestation reduces biomass stocks. Given increasing demand for charcoal, and decreasing availability of biomass, policies are urgently needed that ensure secure energy supplies for urban households and reduce deforestatio...
