A practically simple top-down process for the exfoliation of graphene (GN) and few-layer graphene (FLG) from graphite is described. We have discovered that a biocompatible amphiphilic pyrene-based hexahistidine peptide is able to exfoliate, functionalize, and dissolve few layer graphene flakes in pure water under exceptionally mild, sustainable and virtually innocuous low intensity cavitation c...

Many proteins that accumulate in the form of insoluble aggregates when they are overproduced in Escherichia coli can be rendered soluble by fusing them to E. coli maltose binding protein (MBP), and this will often enable them to fold in to their biologically active conformations. Yet, although it is an excellent solubility enhancer, MBP is not a particularly good affinity tag for protein purifi...

In this article, I examine how Sissieretta Jones (frequently described as America’s first Black superstar, among other superlatives) strategically leveraged her European performance reviews in order to increase listenership and wages the United States. toured Europe for (and only) time from February until November 1895. According clippings that she provided African American newspapers, singer p...

A surface plasmon resonance imaging-based Ni(2+)-iminodiacetic acid-coated gold chip system was developed to enable specific detection of a hexahistidine-tagged recombinant protein in crude extracts or in column chromatography fractions. This system is especially advantageous for high-throughput analysis of multiple proteins.

Fluorescent probes are essential for the exploration of protein function, detection of molecular interactions, and conformational changes. The nitrilotriacetic acid derivatives of different chromophores were successfully used for site-selective noncovalent fluorescence labeling of histidine-tagged proteins. All of them, however, suffer from the same drawback--loss of the fluorescence upon bindi...

Affinity tags have become powerful tools from basic biological research to structural and functional proteomics. They were widely used to facilitate the purification and detection of proteins of interest, as well as the separation of protein complexes. Here, we mainly discuss the benefits and drawbacks of several affinity or epitope tags frequently used, including hexahistidine tag, FLAG tag, S...

Three cross-cultural studies conducted among U.S. and Indian adults compared perceptions of helping friends in strongly versus weakly expected cases, views of helping family versus strangers, and responses to a self-determination motivation scale. Expectations to help family and friends were positively correlated with satisfaction and choice only among Indians and not among Americans. Also, whe...

Background: Individuals from South Asia have high diabetes prevalence despite low body weight. We compared the prevalence of diabetes among South Asian Indians with other U.S. ethnic groups and explored correlates of diabetes. Methods: This was a cross-sectional study of 150 South Asian Indians (ages 45–79) in California, using similar methods to the Multi-Ethnic Study of Atherosclerosis (MESA)...

This paper explores the multi-dimensional Asian American identity of immigrant Indians from their interview responses. Pan-ethnic in US as Americans, Mar Thoma Church community for religious identity, and second-generation Patel family’s union formation terms gender will be analyzed to find out reasons behind choice a particular identity. Historical frameworks like movement theoretical theories...

The article presents and analyses the first part of Norwegian educator Hartvig Nissen’s (1815–1874) comprehensive report from his study tour to Scotland in 1853. Nissen occupies an important place nineteenth-century educational history general, he is regarded as main driving force behind most School Act, ratified 1860. sheds light upon how presented Scottish school system state education at tim...
