Phase-separated multi-molecular assemblies provide a general regulatory mechanism to compartmentalize biochemical reactions within cells. We propose that a phase separation model explains established and recently described features of transcriptional control. These features include the formation of super-enhancers, the sensitivity of super-enhancers to perturbation, the transcriptional bursting...

the extended hildebrand solubility parameter approach (ehsa) is used to estimate the solubility of satranidazole in binary solvent systems. the solubility of satranidazole in various water-peg 400 mixtures was analyzed in terms of solute-solvent interactions using a modified version of hildebrand-scatchard treatment for regular solutions. the solubility equation employs term interaction energy ...

Cell-specific expression of many genes is conveyed by multiple enhancers, with each individual enhancer controlling a particular expression domain. In contrast, multiple enhancers drive similar expression patterns of some genes involved in embryonic development, suggesting regulatory redundancy. Work in Drosophila has indicated that functionally overlapping enhancers canalize development by buf...

Super-enhancer is a newly proposed concept, which refers to clusters of enhancers that can drive cell-typespecific gene expression and are crucial in cell identity. Many disease-associated sequence variations are enriched in the super-enhancer regions of disease-relevant cell types. Thus, super-enhancers can be used as potential biomarkers for disease diagnosis and therapeutics. Current studies...

barium sulfate (barite) is one of the widely used weighting materials in the preparation of drilling fluid for deep oil and gas wells. barite is not soluble in the regular solvents; such as, hydrochloric acid (hcl) and other acids. therefore, in this study, we focused on evaluating the dissolution of the industrial barite particles in different chelating agents. chelating agents; such as, dieth...

Pain management is a significant challenge due to the side effects associated with commonly prescribed medications like NSAIDs and opioids. Local anesthetics, such as lidocaine, offer an alternative fewer when formulated in topical patches. Transdermal delivery systems, including heated patches, enhance drug absorption provide targeted pain relief. This research paper aims develop characterize ...

Enhancers act over many kilobase pairs to activate target promoters, but their activity is constrained by insulator elements that prevent indiscriminate activation of nearby genes. In the July 1, 2009, issue of Genes & Development, Chopra and colleagues (pp. 1505-1509) report that promoters containing a stalled Pol II are activated by enhancers, but these promoters also serve as insulators that...

Cis-regulatory modules are non-protein-coding regions of DNA essential for the control of gene expression. One class of regulatory modules is embryonic enhancers, which drive gene expression during development as a result of transcription factor protein binding at the enhancer sequences. Recent comparative studies have begun to investigate the evolution of the sequence architecture within enhan...

the goal of the study is to evaluate the sensitivity of czech physicians to the early diagnosis of dementia in patients with memory impairment.a retrospective observational study was designed. we have reviewed the electronic medical records of patients who have been hospitalized for the first time due to dementia of any type at the kromeriz mental hospital from january 1, 2012 to december 31, 2...

The properties of a variety of mouth protectors and sheet materials used to fabricate custom mouth protectors were determined in order to recommend limits for a specification. Hardness, water sorption, water solubility, impact absorption, and tear strength were measured, and limits for these properties were suggested.
