The diketone 2-fluoro-2-(trifluoromethyl)-1-phenylhexane-1,5-dione 3 was synthesized by a Mukaiyama Michael type reaction from the corresponding tetrafluoroenol silyl ether prepared from pentafluoropropiophenone. This diketone was treated under basic conditions and was converted, depending on the stoichiometry of the base, into the surprisingly stable ketol 4-fluoro-4-(trifluoromethyl)-3-hydrox...

background: genital warts are the most common viral sexually transmitted disease affecting 1% of the population. a prospective, open-label controlled trial was performed to compare topical 5% potassium hydroxide (koh) solution with co2 laser in the treatment of female genital warts. methods: seventy patients were enrolled in the study after convenience sampling. right-sided lesions of the patie...

Treatment of Aspergillus fumigatus with echinocandins such as caspofungin inhibits the synthesis of cell wall β-1,3-glucan, which triggers a compensatory stimulation of chitin synthesis. Activation of chitin synthesis can occur in response to sub-MICs of caspofungin and to CaCl2 and calcofluor white (CFW), agonists of the protein kinase C (PKC), and Ca(2+)-calcineurin signaling pathways. A. fum...

This study was conducted to investigate the condition of frying oil used for frying chicken nuggets in a deep fryer. The acidification of the frying oils used, soybean oil (SB), canola oil (CA), palm oil (PA), and lard (LA), were determined as peroxide value, acid value, and fatty acid composition, after chicken nuggets were fried in them for 101 times. The acid value and peroxide value obtaine...

Surface texturization is well known as one of the major paths to improve the conversion efficiency of silicon solar cells by increasing the short-circuit current through the enhancement in antireflection property and effective photon trapping. Compared to the antireflection coating, it is more lasting and effective process. The anisotropic texturing of a (100) n-type monocrystalline silicon sur...

higher NDF content than samples from C with samples from A being intermediate (12.0 vs. 8.4 vs. 9.3%; P ≤ 0.001). The Ca (0.43 vs. 0.31 and 0.40%) and K (2.52 vs. 2.11 and 2.21%) content were higher in A samples than in B samples, with C samples being intermediate (P ≤ 0.01). The C samples had higher PDI (22.6 vs. 15.2 vs. 20.1%) and TI content (3.9 vs. 2.8 and 3.4 g/kg) than B samples with A s...

A simple histochemical procedure for assessing relative amounts of neutral and acidic sugars in mucin glycoproteins, and its application in the study of cyclical changes ofhuman cervical mucins, is described. This procedure, the saponification/selective periodate oxidation/borohydride reduction/alcian blue pH 2-5/periodic acid Schiff (KOH/PA*/Bh/Ab 2-5/PAS) method, uses a selective oxidation st...

Diving-related tourism is known to contribute both directly and indirectly to reef degradation around the globe, including Koh Tao, a popular diving destination in the Gulf of Thailand. Of the known publications on reef threats at Koh Tao, only three mention the effects of highly abundant coral predators. The present study combines results of a nine-year long period (2006–2014) of reef surveys ...

Zeolitic products formed by hydrothermal treatment of coal fly ash (FA) with KOH aqueous solution under various reaction conditions were examined. Only linde F-type zeolite (K2Al2Si2O8·3H2O) was newly formed at atmospheric pressure, except formation of a small amount of kalsilite (KAlSiO4) at longer reaction time. The yield of the linde F zeolite was highest when reaction time, temperature, KOH...
