BACKGROUND Although molluscum contagiosum (MC) resolves spontaneously, there are several reasons to treat this dermatological disorder. OBJECTIVE To evaluate the safety and efficacy of 5% imiquimod cream versus 10% potassium hydroxide (KOH) solution in treating MC, and to propose the mechanism of cure by observing the histological findings. METHODS Imiquimod or KOH were applied by the patie...

Porous sulphur-doped carbons have been prepared by using polythiophene (PTh) as carbon precursor and KOH as activating agent. The activation process was carried out under several operating conditions, i. e. a KOH/PTh weight ratio of 2 or 4, and reaction temperatures in the 600-850 oC range. The porous carbons thus obtained exhibit very large apparent surface areas and high pore volumes of up to...

Adiabatic ionization energy (AIE) calculations were performed at the AM1, PM3, PM6, PDDG, HF/QZVP, and B3LYP/QZVP levels of theory on 722 atmospherically relevant organic compounds with available experimental kOH . From the starting set of molecules, a final suite of 114 monoand polyfunctionalized compounds provided converged neutral and cationic geometries without imaginary frequencies for all...

Nitrogen dioxide is formed during delivery of inhaled nitric oxide for the treatment of patients with pulmonary hypertension. Soda lime has been shown to absorb nitrogen dioxide. We tested three different commercially available soda lime preparations (Sodasorb, Drägersorb 800 and Sofnolime) for their efficacy in absorbing nitrogen dioxide and nitric oxide during simulated nitric oxide inhalatio...

Poly(L/D)lactide 96/4 fibres with diameters of 50 and 80 microm were produced. The smaller diameter fibres were carded and needle punched to form a non-woven mat. Fibres and non-woven mats were hydrolysed for a period of 20 weeks. Fibres and pressed non-woven discs were treated with low-temperature oxygen plasma and alkaline KOH hydrolysis and ethanol washing was used as a reference treatment. ...

Conditions to increase phenolic hydroxyl groups (OH-Phe) in organosolv lignin using alkaline catalysts (NaOH and KOH) were optimized with the purpose of increasing the reactivity of lignin and to evaluate the effect on the structure of the newly generated compounds as a result of the basecatalyzed depolymerization (BCD). The lignin-derived compounds could be used for the synthesis of bio-based ...

Nanostructured potassium-incorporated Ti-based oxides have attracted much attention because the incorporated potassium can influence their structural and physico-chemical properties. With the aim of tuning the structural and physical properties, we have demonstrated the wet corrosion process (WCP) as a simple method for nanostructure fabrication using various Ti-based materials, namely Ti-6Al-4...

Ball-milled alcohol-insoluble residue (AIR) was prepared from switchgrass (Panicum virgatum var Alamo) and sequentially extracted with 50 mM ammonium oxalate buffer, 50 mM sodium carbonate, 1 M KOH containing 1% NaBH(4), and 4 M KOH containing 1% NaBH(4). Arabinoxylan was the most abundant component of the 1 M KOH-extracted fraction, which was treated with endoxylanase to generate oligosacchari...

lamerin microspridia (lbms) isolated from lamerin breed of the silkworm, bombyx mori, l. and the standard strain nosema bombycis, were induced to germinate artificially by two-step procedure. fresh percoll purified spores were activated by incubating them in potassium hydroxide solution (koh) (ph 11.00) and germinated artificially by using phosphate buffer saline (pbs), (ph 7.00). germinated sp...

BACKGROUND Plane wart is a common dermatological disease that is caused by human papilloma virus; although the rate of spontaneous recovery is high, it usually takes a long time to occur. Many modalities of treatments have been used but none of them proved to be uniformly effective. Potassium hydroxide (KOH) solution is a well-known keratolytic agent with many dermatological uses. OBJECTIVE T...
