We have used correlated scanning EM (SEM) and multiphoton fluorescence microscopy to visualize budding of virus-like particles (VLPs) of Rous sarcoma virus (RSV) and HIV type 1 (HIV-1). When the Gag structural protein was expressed alone as a GFP fusion, most budding particles appeared morphologically aberrant, but normal assembly could be rescued by coexpression of untagged Gag protein. Imagin...

Background: Relatively little has been reported comparing the ability of different induced pluripotent stem cells (iPSCs) and protocols to derive human intestinal organoids (HIO), although there is potential to supply HIO for translational research and regenerative medicine. In view of the time and effort required to differentiate HIO, protocols for differentiation were compared and five iPSC l...

Model organisms, especially the budding yeast, are leading systems in the transformation of biology into an information science. With the availability of genome sequences and genome-scale data generation technologies, the extraction of biological insight from complex integrated molecular networks has become a major area of research. Here I examine key concepts and review research developments. ...

After more than a century since its birth, Quantum Theory still eludes our under1 standing. If asked to describe it, we have to resort to abstract and ad hoc principles about 2 complex Hilbert spaces. How is it possible that a fundamental physical theory cannot be de3 scribed using the ordinary language of Physics? Here we offer a contribution to the problem, 4 providing a short non-technical p...

Current studies are either region-limited, sole-species, or have short researching periods; so, studies about various species are necessary throughout South Korea. In this study, trends of changes in the budding and flowering dates of spring plants by climate factors served to explore the process of urbanization. Four common species, such as Forsythia koreana (forsythia), Rhododendron mucronula...
