Structural Features of Carbons Produced Using Glucose, Lactose, and Saccharose
Glucose, lactose, and saccharose were used as precursors to prepare chars at 400 °C then activated at 800 °C or 1000 °C in closed vessels with controlled amounts of oxygen penetrating through nanopores in the vessel walls. There are correlations between the porosity, amounts of residual O- and H-containing functionalities, and electroconductivity of amorphous carbons studied. The pore size dist...
متن کاملThe flexibility of locally melted DNA
Protein-bound duplex DNA is often bent or kinked. Yet, quantification of intrinsic DNA bending that might lead to such protein interactions remains enigmatic. DNA cyclization experiments have indicated that DNA may form sharp bends more easily than predicted by the established worm-like chain (WLC) model. One proposed explanation suggests that local melting of a few base pairs introduces flexib...
متن کاملInfluence of saccharose on the development of cercariae from Schistosoma mansoni strains BH and SJ.
The development of cercariae from Schistosoma mansoni strains BH and SJ in Biomphalaria glabrata and Biomphalaria tenagophila treated with saccharose was studied. The molluscs were maintained in dechlorinated tap water containing 0.01% saccharose. After one week of treatment with saccharose, B. glabrata and B. tenagophila were exposed to ten S. mansoni miracidia, from BH and SJ strains respecti...
متن کاملAdsorption of Melted Drugs onto Smectite
Montmorillonite, a 2:1 clay mineral, is known to accommodate different organic substances within its interlayer space to form intercalation compounds, which have received much attention because of their stability and physicochemical properties. Its use as a drug carrier is widely studied, as the location of the drug molecules within the interlayer space of the clay may modify the suitability of...
متن کاملStroke following injection of a melted suppository.
BACKGROUND AND PURPOSE Stroke following the intravenous injection of drugs may be secondary to the direct effect of the substance itself or from embolization by the inert vehicle used in the manufacturing process of the drug. CASE DESCRIPTION We describe a 39-year-old man who developed a left homonymous hemianopia after intravenous injection of a melted suppository. CONCLUSIONS Paradoxical ...
