BACKGROUND Eukaryotic transcription is accompanied by combinatorial chromatin modifications that serve as functional epigenetic markers. Composition of chromatin modifications specifies histone codes that regulate the associated gene. Discovering novel chromatin regulatory relationships are of general interest. METHODOLOGY/PRINCIPAL FINDINGS Based on the premise that the interaction of chroma...

PURPOSE OF REVIEW Cell xenotransplantation has the potential to provide a safe, ethically acceptable, unlimited source for cell replacement therapies. This review focuses on genetic modification strategies aimed to overcome remaining hurdles standing in the way of clinical porcine islet transplantation and to develop neural cell xenotransplantation. RECENT FINDINGS In addition to previously d...

background: development of tissue engineering and regenerative medicine has led to designing scaffolds and their modification to provide a better microenvironment which mimics the natural niche of the cells. gelatin surface modification was applied to improve scaffold flexibility and cytocompatibility. methods: plla/pcl aligned fibrous scaffold was fabricated using electrospinning method. adscs...

introduction: the purpose of the current study was to investigate the effect of training behavior modification methods to mothers of children with attention deficit disorder (adhd) on reducing behavior problems and adhd symptoms in their children’s. method: the research method was quasi-experimental with pre-test and post-test design and cotrol group. to do so, 24 mothers of children with adhd ...

The formation of microporosity in modified Al-Si alloys has been reviewed in the present study. A major concern in modification is the increased tendency to form microporosity in the macro-shrinkage free Al-Si alloy castings. It has also been demonstrated that at low hydrogen contents (0.1cc/ 100g, Al), where only shrinkage porosity should occur, the effect of Sr-modification on porosity conten...

Diminishing of conventional fuels and hysterical vehicles emission leads to deterioration of the environment, which emphasize the research to work on biofuels. Biofuels from different sources attract the attention of research due to low emission and biodegradability. Emission of carbon monoxide, carbon dioxide and H-C reduced drastically using Biofuels (B-20) combustion. Contrary to the convent...

Bacterial flagella are particularly attractive bio-templates for nanotubes due to their tubular structures and small inner and outer diameters. In this work, flagella isolated from Salmonella typhimurium were used as templates for silica-mineralized nanotubes. The process involved pretreatment of flagella with aminopropyltriethoxysilane (APTES), followed by the addition of tetraethoxysilane (T...

OBJECTIVE The objective of the study was recognition of the opinions of adolescents completing secondary schools concerning genetically modified organisms and genetically modified food, especially the respondents' emotional attitude towards scientific achievements in the area of live genetically modified organisms. MATERIAL AND METHOD The study covered a group of 500 school adolescents comple...

This paper develops a model of differentiated consumers to examine the consumption effects of genetic modification (GM) under alternative labeling regimes and segregation enforcement scenarios. Analytical results show that if consumers perceive GM products as being different than their traditional counterparts, genetic modification affects consumer welfare and, thus, consumption decisions. When...
