Abstract

With the total amount of worldwide data skyrocketing, the global data storage demand is predicted to grow to 1.75 × 1014 GB by 2025. Traditional storage methods have difficulties keeping pace given that current storage media have a maximum density of 103 GB/mm3. As such, data production will far exceed the capacity of currently available storage methods. The costs of maintaining and transferring data, as well as the limited lifespans and significant data losses associated with current technologies also demand advanced solutions for information storage. Nature offers a powerful alternative through the storage of information that defines living organisms in unique orders of four bases (A, T, C, G) located in molecules called deoxyribonucleic acid (DNA). DNA molecules as information carriers have many advantages over traditional storage media. Their high storage density, potentially low maintenance cost, ease of synthesis, and chemical modification make them an ideal alternative for information storage. To this end, rapid progress has been made over the past decade by exploiting user-defined DNA materials to encode information. In this review, we discuss the most recent advances of DNA-based data storage with a major focus on the challenges that remain in this promising field, including the current intrinsic low speed in data writing and reading and the high cost per byte stored. Alternatively, data storage relying on DNA nanostructures (as opposed to DNA sequence) as well as on other combinations of nanomaterials and biomolecules are proposed with promising technological and economic advantages. In summarizing the advances that have been made and underlining the challenges that remain, we provide a roadmap for the ongoing research in this rapidly growing field, which will enable the development of technological solutions to the global demand for superior storage methodologies.

26. Integumental amino acid uptake in a carnivorous predator mollusc (Sepia officinalis, Cephalopoda)

Abstract

The epithelial cells of the integument of body, arms and tentacles of Sepia officinalis present on their apical membrane a well-organised brush border and show the morphological and histochemical characteristics of a typical absorptive epithelium. The ability of the integument to absorb amino acids was investigated both in the arms incubated in vitro and in a purified preparation of brush border membrane vesicles (BBMV). Autoradiographic pictures of the integument after incubation of the arms in sea-water with or without sodium, showed that proline intake was Na+-dependent, whereas leucine intake appeared to be a largely cation-independent process. Time course experiments of labelled leucine, proline and lysine uptakes in BBMV evidenced that these amino acids are accumulated within the vesicles in the presence of an inwardly directed sodium gradient. The sodium-driven accumulation proves that cationic and neutral amino acids are taken up by the apical membrane of the epithelium of Sepia integument through a secondary active mechanism. For leucine, a 90% inhibition of the uptake was recorded in the presence of a large excess of the substrate. In agreement with the autoradiography results, an analysis of the cation specificity transport in BBMV showed that leucine uptake had a low cation specificity, whereas lysine and proline uptakes were Na+-dependent. An excess of lysine and proline, which share with alanine two different transport systems in the gill epithelium of marine bivalves, reduced eucine uptake. The possible role of the absorptive ability of the integument in a carnivorous mollusc is discussed

29. Structural and biochemical analysis of the parasite Gordius villoti(Nematomorpha, Gordiacea) cuticle.

Author

Brivio, M.F., Eguileor, M.de, Grimaldi, A., Vigetti, D., Valvassori, R., and Lanzavecchia, G.

Abstract

The cuticle of the nematomorpha Gordius villotiis a proteinaceous extracellular structure that covers the body during the endoparasitic life in the hemocoelic cavity of insect hosts, and of the free-living adult animals. The ultrastructure of the cuticle has a complex spatial organization with several parallel layers of large diameter fibers, interposed thinner fibrous elements and honeycomb-shaped matrix surrounding the fibers. When adult isolated cuticles were partially solubilized by several compounds, the structure revealed a strong insolubility and the main fibers were always observable. HPLC and spectrophotometric assays carried out to investigate the presence of tyrosine cross-linking, indicated such a mechanism as a key-element in the hardening process of the cuticle. Such data strongly suggest that the Gordiuscuticle contains dityrosine compounds, whose formation is probably mediated by endogenous peroxidase activity.

30. T-system in muscles of microdriles

Author

Eguileor, M., Valvassori, R., Lanzavecchia, G., and Lernia, L.

Abstract

Ribbon-like longitudinal fibers of the body wall of enchytraeids and lumbriculids are grouped in fuctional units. The organization of subsarcolemmal cisternae, membrane foldings and extracellular spaces between fibers is described. The data seem to indicate that the spaces between fibers within each functional unit are interpretable as T-tubules of a cross-striated fiber.

32. Microstrains and stacking faults in deformed magnetites: A study by X-ray diffraction

Author

Fagherazzi, G and Lanzavecchia, G

Abstract

By means of the study of the shape, the breadth and the position of the X-ray diffraction lines, microstrains and stacking faults have been identified and measured in mechanically treated magnetites. Hornstra's theory is thus experimentally verified. By annealing at 500°C the values of microstrains decrease and stacking faults disappear.
