soil can register environmental pollution in itself, so the pollution of an area can be studied through the chemical analysis of its soil. in the present study, the soil ofmellatparkintehranwas sampled. in total, 15 soil samples were collected. using laboratory methods, the mean concentration of pb, zn, and ni were obtained to be 145, 33, and 62 mg/kg, respectively. the results show that the co...
Establishment and maintenance of heritable chromatin structure during early Drosophila embryogenesis
During embryogenesis, the initial chromatin state is established during a period of rapid proliferative activity. We have measured with 3-min time resolution how heritable patterns of chromatin structure are initially established and maintained during the midblastula transition (MBT). We find that regions of accessibility are established sequentially, where enhancers are opened in advance of pr...
Spectacular advances in the throughput of DNA sequencing have allowed genome-wide analysis of epigenetic features such as methylation, nucleosome position and post-translational modification, chromatin accessibility and connectivity, and transcription factor binding. However, for rare or precious biological samples, input requirements of many of these methods limit their application. In this re...
In this research, a novel method is reported for the surface grafting of n-vinylcaprolactam as a thermosensitive agent and 3-allyloxy-1,2-propandiol with an affinity toward ceftriaxone onto modified magnetic nanoparticles by 3-mercaptopropyltrimethoxysilane. The grafted nanoparticles were characterized by Fourier Transform Infrared Spectroscopy, Elemental Analysis, and Vibrating Sample Magnetom...
Biobanking is a widespread practice for storing biological samples for future studies ranging from genotyping to RNA analysis. However, methods that probe the status of the epigenome are lacking. Here, the framework for applying the Assay for Transposase Accessible Sequencing (ATAC-seq) to biobanked specimens is described and was used to examine the accessibility landscape of naïve B cells from...
It is well established that epigenetic modulation of genome accessibility in chromatin occurs during biological processes. Here we describe a method based on restriction enzymes and next-generation sequencing for identifying accessible DNA elements using a small amount of starting material, and use it to examine myeloid differentiation of primary human CD34+ cells. The accessibility of several ...
Knowing about the evolution of a term can significantly decrease time needed for searching for information. It can also aid in quickly getting a broader overview, which is essential when one is on the move. In this paper we present a solution for providing language evolution knowledge “on the go”. We present a mobile interface for easy access and visualization as well as an overview of how this...
Functionalists about consciousness identify consciousness with a role; physicalists identify consciousness with an implementer of that role. The global workspace theory of consciousness fits the functionalist perspective, but the physicalist sees consciousness as a biological phenomenon that implements global accessibility.
