It has been reported that the repeated topical, nonoccluded application of acetone may modulate antibody production in mice, thus producing humoral immunosuppression. However, the evaporative loss expected following nonoccluded dermal application of acetone makes the systemic effect seem unlikely. This stud...
Why does ethanol made by fermentation have to be purified? How does water gets to the lungs and how can water be exhaled if it is liquid form? Why is 2-Methyl Propan-2-ol viscous and a solid at room temperature? Why are glucose and oxygen important in aerobic respiration?
Why does fatty acids solubility decrease in a non-polar solvent (such as benzene)? Why does stearic acid melt quickly? Why do some oxidizing agents have to be in an acid medium? What does it mean when we say that concentrated nitric acid has 16 molars?
The tool was used in its standard configuration and using H3O+ as a reagent ion. Before starting the experiment, a multi-component standard gas containing methanol, acetaldehyde, acetone, and monoterpene mixture (Apel-Riemer Environmental Inc., Broomfield, CO, USA) was used to calibrate the ...

Specimens were rinsed in 0.15 M sodiumcacodylate buffer containing 3 mM CaCl2, pH 7.4 postfixed in 2% osmium tetroxide in 0.07 M sodiumcacodylate buffer containing 1.5 mM CaCl2, pH 7.4 at 4°C for 2 h, dehydrated in ethanol followed by acetone and embedded in LX-112 (Ladd, Burlington, ...
Each mouse was treated with 1 ml of a solution of 1 μg per ml tamarind XG or OGA in PBS. The mice were sensitized with 0.3% DNFB in acetone 3 d later and challenged 6 d after sensitization. g Mice were exposed to 2 kJ per m2 UVB from FS40 sunlamps on their shaved abdominal ski...
2,3 Mg and its alloys have been considered as one of the most promising biodegradable medical devices, but it was still unclear whether hypermagnesemia involved health risks would occur in persons with kidney disease due to their deteriorated kidney function for Mg ions excretion from their body...
Nonpolar compounds aregenerally more soluble indiethyl ether than in alcohols such as ethanol because ethers do not have a hydrogen bonding network that would have to be broken up to dissolve the solute. Because diethyl ether has a dipole moment, polar substances readily dissolve in it. ...
Results The 50mm Rezex RFQ Fast Acid H+ guard column was able to separate the most common fermentation products (ethanol, acetone, iso- and n-butanol) and promising precursors (furfural and 5-hydroxymethylfurfural) of biofuels and value-added chemicals. Compound profiles in fermentation samples ...
