one of the main components of lung alveoli is surfactant. dppc (dipalmitolphosphatidylcholine) is thepredominant lipid component in lung surfactant that is responsible for lowering surface tension in alveoli in thisarticle. we used a very approximate model with computational method of ab initio to describe the interactionsbetween dppc as important component of lung surfactant and some chemical ...

the aim of this study was to compare three routine precipitation methods, including: acetone, tca/acetone wash and tca/acetone. 30 plasma samples were precipitated using above mentioned three methods. pellets were dissolved in rehydration solution and protein quantification was done for this solution. according to statistical analysis using spss ver 16.0 software and one-way anova test, the pro...

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...

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, ...

objective: comparing the effect of repeated opening of the container lid of two dentin adhesive systems, prime&bond; nt (p&b; nt) and ibond (ib), on shear bond strength. materials and methods: intact bovine lower incisors (n=60), fixed in acrylic were ran-domly divided into six groups (n=10). groups i and ii were set as control groups. p&b; nt and ib were applied on the samples after five days ...
