Long-Term Storage ofCryptosporidium parvumfor In Vitro Culture

Long-term in vitro culture of wheat grains.

Wheat (Triticum aestivum, Triticum durum) grains were excised immediately following fertilization and cultured until maturity. A rachis fragment attached to the grain was required to ensure an increase in grain size for the first 10 days following fertilization. A (14)C-labeling study revealed that 8-day-old grains accumulated more dry matter into the ethanol-insoluble fraction when grown on ag...

Financing Long-term Care: The Role of Culture and Social Norms; Comment on “Financing Long-term Care: Lessons From Japan”

Based on the experiences of Japan and Germany, Ikegami argues that middle-income countries should introduce public long-term care insurance (LTCi) at an early stage, before benefits have expanded as a result of ad hoc policy decisions to win popular support. The experience of the Netherlands, however, shows that an early introduction of public LTCi may not prevent, but ...

How Long Is Long-Term Data Storage?

In the context of archiving of physical documents, long-term storage has long been accepted to mean centuries. Digital documents are much more ephemeral, so archivists should be aware of the inherent limitations of the technologies available for preservation of digital data. This paper compiles the results of several studies on this subject, in addition to presenting new findings on what can be...

propagation of human germ stem cells in long-term culture

background: spermatogonial stem cells (sscs), a subset of undifferentiated type a spermatogonia, are the foundation of complex process of spermatogenesis and could be propagated in vitro culture conditions for long time for germ cell transplantation and fertility preservation. objective: the aim of this study was in vitro propagation of human spermatogonial stem cells (sscs) and improvement of ...
