Background: Although evidence indicates that tobacco use is one of the risk factors for oral cancer, the relationship between opium addiction and oral cancer has not yet been evaluated. The present study was performed aiming to evaluate P53 and epidermal growth factor receptor (EGFR) expression in the gingival tissue of opium-dependent patients.Methods: 102 individuals (70 men and 32 women) wer...

We estimated the amount of test solution absorbed by each Chromosorb W AW particle (60-80 mesh) using an isotopic technique to quantitate the particle method. 14C-Labeled standard compounds like carbendazim (MBC), 5-O-methylcochliophilin A, sucrose and proline were dissolved in several solvents, and Chromosorb carrier particles were treated with the solution to coat the particle with these test...

the ataxia telangiectasia mutated gene (atm), candidate for breast cancer susceptibility gene, encode a 350-kda protein belongs to the core components of dna-damage response machinery. female at carriers have at least 5-fold increase risk for breast cancer. reduction in atm expression is shown in multiple studies in breast tissues. we aimed to perform a research to measure the atm mrna expressi...

The hypothesis that “protein amino acid sequence determines the final shape a protein assumes in a water solution” was proven to be correct when Christian B. Anfinsen showed that if the enzyme ribonuclease was opened out into a linear chain and then allowed to reform, it reassumed the correct catalytic shape. This experiment is a critical one in the understanding of the nature of gene expressio...

objective: a significant increase in violence in the world and its impact on public health and ‎society can be an important reason to offer solutions to reduce or control anger. studies ‎have shown that specific food groups may be effective in controlling mental disorders ‎such as depression, anxiety and anger. the purpose of this study was to determine the ‎relationship between food intake and...

In the present research synthesis of zeolites, merlinoite minerals of natural clinoptiloite mineral in the presence of alkaline mediums, was investigated. The analyzed variants are a result of a concentration of Na+ and K+ ions, temperature and time. Phase transition of clinoptiloite was conducted in the presence of an 8 molar potash solution (KOH) and a 4 molar soda solution (NaOH). Results in...

This paper presents a novel procedure for solving the equations system of the rotating crack model used for reinforced concrete. It is implemented in the programme NonOPt where it is used to optimise the reinforcement design of D regions. The procedure is based on solving explicit closed-form relations without the need to incrementally increase the applied loads. The solution procedure is based...
