Eukaryotic gene expression occurs in the context of chromatin, and maintaining a region accessible to DNA-binding proteins for transcriptional regulation requires active processes that mobilize nucleosomes. Our approach to studying these processes has been to map nucleosome dynamics genome-wide, and we have introduced several different strategies to achieve this goal: (1) To measure relative le...
Single-walled carbon nanotubes (SWNTs) have unique properties and are projected to have a major impact in nanoscale electronics, materials science, and nanomedicine. Yet, these potential applications are hindered by the need for sample purification to separate SWNTs from each other and from metallic catalyst and amorphous carbon present in as-synthesized samples. Common purification strategies ...
This study describes the isolation and purification of a phytocystatin from seeds of Brassica juncea (Indian mustard; cultivar RoAgro 5444), which is an important oilseed crop both agriculturally and economically. The protein was purified by gel filtration chromatography with 24.3% yield and 204-fold purification, and visualised by 2D gel electrophoresis. The 18.1 kDa mustard cystatin was highl...
development programs formulated in order to influence and create change and improvement in people's lives, that entails the promotion of resources, opportunities and capabilities different sections of the population, as well as an improvement in the standards and quality of life. they are based on policies that presented in form concrete objectives and articles program. this policies and o...
High-resolution mapping of chromatin features has emerged as an important strategy for understanding gene regulation and epigenetic inheritance. We describe an in vivo tagging system coupled to chromatin purification for genome-wide epigenetic profiling in Caenorhabditis elegans. In this system, we coexpressed the Escherichia coli biotin ligase enzyme (BirA), together with the C. elegans H3.3 g...
We develop the idea of creating wastewater treatment facilities for biosphere compatible buildings with maximum-closed cycles with respect to water and energy. The idea started from experiments with closed-loop ecological Life Support Systems for space flights carried out in the 60s-80s last century. Water recycling is accomplished by functioning the microalgae-bacteria human ecosystem. One of ...
The transcriptional coactivator ANGUSTIFOLIA3 (AN3) stimulates cell proliferation during Arabidopsis thaliana leaf development, but the molecular mechanism is largely unknown. Here, we show that inducible nuclear localization of AN3 during initial leaf growth results in differential expression of important transcriptional regulators, including GROWTH REGULATING FACTORs (GRFs). Chromatin purific...
Recent years have seen remarkable development in open quantum systems effectively described by non-Hermitian Hamiltonians. A unique feature of topological is the skin effect, anomalous localization an extensive number eigenstates driven nonreciprocal dissipation. Despite its significance for phases, relevance effect to entanglement and critical phenomena has remained unclear. Here, we find that...
for more than three decades, oxidative coupling of methane (ocm) process has been comprehensively investigated as an attractive alternative for the commercially available ethylene production technologies such as ethane and naphtha cracking. developing a suitable catalyst and proper reactor feeding policy, reviewing and deploying the efficient methods in the separation and purification of the un...
Abstract Background As wild poliovirus is eradicated, preventing circulation of vaccine-derived top priority. Our lab developed real-time multiplex PCR assays and deep sequencing methodology to detect characterize OPV strains from stool samples. The method requires gel purification product created viral RNA in However, the process filters out a significant portion Here, we compare gel- vs. DNA-...
