PURPOSE Surgical excision is the definitive treatment for localized recurrence of papillary thyroid carcinoma. Reoperation for recurrence, however, is challenging and associated with increased operative times and complication rates. For safe and effective reoperation, ultrasound-guided charcoal tattooing localization can be used. The aim of this study was to investigate the feasibility and safe...

Formation of C–C, C–N, and C–H bonds using three heterogeneous catalysts in the form of nickel-in-charcoal (Ni/C), nickel-on-graphite (Ni/Cg), and copper-in-charcoal (Cu/C) are described.

Biomass fuels, charcoal and kerosene are the most used cooking fuels in Tanzania. Biomass fuel use has been linked to Acute Respiratory Infections (ARI) in children. It is not clear whether the use of charcoal and kerosene has health advantage over biomass fuels. In this study, the effects of biomass fuels, charcoal/kerosene on ARI in children under five years old in Tanzania are quantified and...

The capability of charcoal as a sorbent for helium at cryogenic temperatures depends upon charcoal characteristics that are not well understood. Previous work by the authors has indicated that the charcoals' pumping capability for helium depends as much on their source as on their particle size distributions. To develop a correlation between the physical characteristics of charcoal and helium p...

isovanillin and iso-acetovanillon are two phenolic components isolated from a number of plants including pycnocycla spinosa . p. spinosa extract has antispasmodic and antidiarrheal activities. however, no comparative study has been done on antidiarrheal action of isovanillin and iso- acetovanillon, so far. the aim of this study was to investigate antidiarrheal action of isovanillin and iso-acet...

BACKGROUND Uncoated adsorbent charcoal may regenerate the ultrafiltrate suggesting its use as an endogenous substitution fluid. The objective of this study was to assess the safety and the long-term clinical results. METHODS Thirty-three chronic uraemic patients were dialysed for 1 year using two haemodialysers in series in order to separate convection from diffusion. At the outflow of the co...

We determined if supplemental macronutrients or activated charcoal influenced intake of sagebrush, a shrub that contains terpenes. Sheep (lambs 3 mo age, 33 kg) and goats (kids 5 mo age, 28 kg) were fed supplements high in energy, high in protein, or offered a choice between the two supplements before and after receiving sagebrush for 4 h/d. The effect of activated charcoal, a compound that red...

Biochar applications to soils can improve soil fertility by increasing the soil's cation exchange capacity (CEC) and nutrient retention. Because biochar amendment may occur with the applications of organic fertilizers, we tested to which extent composting with farmyard manure increases CEC and nutrient content of charcoal and gasification coke. Both types of biochar absorbed leachate generated ...
