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, ...

Acetyl coenzyme A is an important molecule in metabolism playing role in many biochemical reactions.  Its main function is to convey the carbon atoms within the acetyl group to the citric acid cycle (Krebs cycle) to be oxidized for energy production. In order to find out if this chemical compound could affect physiological and morphological characteristics of rosemary plant, the present study w...
