TheUSNational Institutes of Health define thewordNanomedicine as “an offshoot of nanotechnology” in the context of “specific medical intervention at the molecular scale for curing diseases or repairing tissues”.1 Other broader definitions promote the term as the application of nanotechnology into the realm of medicine2 for the “preservation and improvement of human health using molecular tools ...

The steroidogenic and lipolytic activities of corticotrophin-(l-24)-tetracosapeptide and [Lys17.18]corticotrophin-(l-18)-octadecapeptide amide were compared with those of the corresponding analogues variously substituted in position 8 with homo-arginine, ornithine or lysine. Peptides substituted with homo-arginine showed a surprisingly high degree of biological activity; in all the tests perfor...

This paper examines a number of social, ethical and cultural issues related to the application of biotechnology. The focus of the paper relies on two different cases of governing biotechnology in Portugal, referring to donation of biological material: the act of donation of eggs and sperm; and volunteers for donation of DNA material for the forensic national DNA database. We analyze the discour...

Millions of biological samples, including cells of human, animal or bacterial origin, viruses, serum/plasma or DNA/RNA, are stored every year throughout the world for diagnostics and research. The purpose of this review is to summarize the resources necessary to set up a bio-banking facility, the challenges and pitfalls of sample collection, and the most important techniques for separation and ...
