Isopropyl has replaced ethyl alcohol in many such pharmaceutical preparations and cosmetics as mouth washes, dental solutions, and hair tonics. Although the physiology and toxicity of this material are fairly well known, a thorough knowledge of the metabolism involves a method for the separate determination of isopropyl alcohol and acetone, the chief product of its oxidation in the body. Many o...

Force fields based on a Lennard-Jones (LJ) 12-6 plus point charge functional form are developed for acetone and chloroform specifically to reproduce the minimum pressure azeotropy found experimentally in this system. Point charges are determined from a CHELPG population analysis performed on an acetone-chloroform dimer. The required electrostatic surface for this dimer is determined from ab ini...

this paper is the first phytochemical and abts cation radical decolorisation activity, cupric reducing antioxidant capacity, anticholinesterase and dna damage protection effect of endemic verbascum pinetorum (boiss.) o. kuntze. phenolic profile of v. pinetorum were qualified and quantified by uhplc-esi-ms/ms analysis. malic acid (47250.61±2504.28 µg/g) and luteolin (7651.96±527.98 µg/g) were fo...

introduction: unstained formalin-fixed whole brain specimens and brain slices do not give satisfactory results for teaching neuroanatomy. in addition, difficulties in obtaining human brains for dissection have increased the demand for more durable brain specimens that have been obtained by the plastination technique. in the present study brain specimens were sliced, fixed and stained using the ...

Bacterial acetone carboxylase catalyzes the ATP-dependent carboxylation of acetone to acetoacetate with the concomitant production of AMP and two inorganic phosphates. The importance of manganese in Rhodobacter capsulatus acetone carboxylase has been established through a combination of physiological, biochemical, and spectroscopic studies. Depletion of manganese from the R. capsulatus growth m...

Propanone is a volatile liquid that can be absorbed by ingestion, inhalation, dermal and is distributed throughout the body. In this study, a fatal case involving acetone poisoning, who was worked in the Red Crescent Medical Center is presented. The deceased was found four hours after death. He was a 25-year-old male nurse and not married. There are the history of smoking since four years ago, ...

Dikstein and Sulman (1) reported that the treatment of the rectus abdominis muscle of Bufo viridis toad with 3.4 M (25%) acetone for 2 minutes eliminated the response of the muscle to acetylcholine (ACh), but 5 to 20 ag/ml of phospholipids such as phospha tidylserine could restore the response of the treated muscle to ACh. They also observed similar effects of phospholipids on the rabbit uterus...

This work presents a new route to design a highly sensitive SnO2-based sensor for acetone gas enhanced by the molecular imprinting technique. Unassisted and acetone-assisted thermal synthesis methods are used to synthesis SnO2 nanomaterials. The prepared SnO2 nanomaterials have been characterized by X-ray powder diffraction, scanning electron microscopy and N2 adsorption-desorption. Four types ...
