Background: The most important researches in molecular and genetic engineering fields are the finding of optimal methods for extraction of the genomic content of microorganisms and cells using them, can achieve the most amount and purity with the least time and cost. There are several methods for the extraction of bacterial DNA and the use of magnetic nanoparticles is one of the novel methods o...

Much research about labeling schemes has been conducted to efficiently determine the ancestor-descendant relationships and the document-order between any two random XML nodes without re-labeling for updates. In this paper, we present an efficient XML encoding and labeling scheme for dynamic XML document, named Continued Fraction-based Encoding (CFE). The proposed CFE scheme labels nodes with co...

Abstract Background and aims: Chloroform, diethyl ether and ammonia are toxic solvents wildly used in forensic labs for preparation and extraction of samples.  The staffs of forensic labs experience high levels of exposure to these solvents. Serious health effects have been reported due to exposure to these solvents including hepatotoxicity, neurotoxicity, carcinogenicity and mutagenicity.   Ma...

This study was carried out to determine a possibility of adding Corni fructus extract (CFE) into yogurt for improving the neutraceutical properties of yogurt and the effects of adding CFE (2∼6%, v/v) on the physicochemical and sensory properties of the products during a 15-day storage period at 4°C. Incorporation of CFE into the yogurt samples resulted in a significant pH reduction and a signif...

Polycyclic aromatic hydrocarbons (PAHs) have been widely studied with respect to their carcinogenic and mutagenic effects on animals and human cells. Phenanthrene (PHE) and fluoranthene (FLU) effects on the needle photosynthetic traits of 2-year-old Japanese red pine (Pinus densiflora Sieb. et. Zucc.) seedlings were investigated. Three months after fumigation of foliage with solutions containin...

A "novel" protocol is presented for easy and reliable estimation of soluble hydroxycinnamate levels in Cichorium intybus L. leaf tissue in large-scale experiments. Samples were standardized by punching 6 discs per leaf, and hydroxycinnamates were extracted by submerging the discs in 80% ethanol with 5% acetic acid for at least 48 h in the darkness at 4°C. Residual dry mass of the discs was used...

A concentrated form of cell free extract (CFE) derived from attenuated Lactococcus lactis supsb. lactis 303 CFE was encapsulated in liposomes prepared from two different proliposome preparations (Prolipo Duo and Prolipo S) using microfluidization. Entrapment efficiencies of 19.7 % (Prolipo S) and 14.0 % (Prolipo Duo) were achieved and the preparations mixed in the ratio 4 (Prolipo Duo):1 (Proli...

A comparison of colony-formation efficiency (CFE) was made between six independent bovine fetal fibroblast (BFF) cell lines used in somatic cell nuclear transfer. Variation in CFE was assessed under different culture conditions. The conditions examined were ambient atmosphere (approximately 20% oxygen) culture versus 5% oxygen culture, three levels of fetal bovine serum (FBS) in the medium (5%,...
