Treatment of rabbits with 1% (v/v) acetone for 1 week resulted in the appearance in blood serum of 88 +/- 14 14 nmol/ml 1-hydroxyacetone (acetol) and 70 +/- 9 nmol/ml 1,2-propanediol. Untreated rabbits had no detectable 1,2-propanediol or acetol. Hepatic microsomes from control, ethanol-, and acetone-treated rabbits catalyzed the hydroxylation of acetone at rates of 0.32 +/- 0.01, 2.01 +/- 0.43...

The aim of this study was the use and revalorization two persimmon by-products A B generated in juice production process. by-product resulting from a pectinase enzymatic treatment peels pulp to optimize extraction especially suitable for recovery valuable bioactive carotenoids. solvents solvent combinations used were: ethanol, acetone, ethanol/acetone (50:50 v/v) ethanol/acetone/hexane (25:25:5...

This study compared the responses of Pd-functionalized and pristine titanate (TiO2) nanotube arrays to ethanol with those to acetone to determine the effects of functionalization of TiO2 nanotubes with Pd nanoparticles on the sensitivity and selectivity. The responses of pristine and Pd-functionalized TiO2 nanotube arrays to ethanol gas at 200 °C were ~2877% and ~21,253%, respectively. On the o...

Ethanol is known to exert a synergistic effect on the toxicity of benzene. In the present investigation it was found that benzene was metabolized at a rate 20-65-fold higher in liver microsomes from ethanol- or acetone-treated rats than in microsomes from control animals. One high affinity site [Km = 19 +/- 5 (SD) microM] and one low affinity site [Km = 0.3 +/- 0.1 mM] for benzene metabolism we...

Background: Plants contain diverse phytochemicals with different solubility levels, depending on their molecular charges and polarity. This study was conducted to examine the effects of three extraction solvents in their pure and aqueous forms: absolute petroleum ether, acetone and ethanol on the phytochemical profile and antioxidant activities of Manihot esculenta leaves extracts. Methods: Th...

Acetone is an important solvent and widely used in the synthesis of drugs and polymers. Currently, acetone is mainly generated by the Cumene Process, which employs benzene and propylene as fossil raw materials. Phenol is a co-product of this synthesis. However, this ketone can be generated from ethanol (a renewable feedstock) in one-step. The aim of this work is to describe the influence of phy...

background & aim: salvia officinalis is known as a traditional medicine for several diseases in countries like lebanon, syria, jordan, etc. in addition, s. officinalis has been subjected to several studies in a try to specify its medicinal effects. this study aims to evaluate the antimicrobial activity of this plant. the aim of the present research was to study antibacterial effects of s. o...

Barberry fruit is consumed in different forms including dried fruit, juice, jam and marmalade in Iran. This fruit is also used as a food additive (flavoring and colorant) in soup and rice dishes. In present study, antioxidant activities of acetone, ethanol and water (infusion and decoction) extracts of barberry (Berberis vulgaris) fruit were investigated using 2,2-azinobis-3-ethylbenzo...

The aim of this study was to evaluate the effect of four different storage media on the elution of monomers from two composite materials. Samples (n = 10, diameter: 4.5 mm, thickness: 2 mm) of two different composite materials (Ceram X™ & Filtek™ Supreme XT) were stored after polymerization in four different media (NaCl, saliva, ethanol 75% & acetone) for 24 h, 7 days, and 28 days. From the sto...

Aims: To examine the existing literature to determine the degree to which percutaneous absorption data obtained using the excised human skin model match those obtained from living man. Methods: The scientific literature was reviewed to collect data on compounds whose percutaneous absorption through human skin had been measured under both in vitro and in vivo conditions. The in vitro-in vivo (IV...
