[Liquid nitrogen biobank: a resource for biomedical research].

Biobanks are a critical resource for "omics" technologies in order to dissect molecular mechanism and gene-environmental interactions of common diseases, such as cancer, cardiovascular diseases, diabetes, and neurodegenerative diseases. Progress in basic biomedicine may contribute to advance personalised medicine in which treatments will no longer be "one size fits all", but instead "tailored" to the molecular and genetic profile of each patient. Currently, there are major efforts worldwide to professionalize biobanks in order to move ahead from a "do-it-yourself" tissue collection - as is most frequent at present - for providing high quality preservation and storage of biological samples with potentially greater scientific impact.

Light quality influences indigo precursors production and seed germination in Isatis tinctoria L. and Isatis indigotica Fort.

Isatis tinctoria L. and Isatis indigotica Fort. are biennial herbaceous plants belonging to the family of Cruciferae that are used as a source of natural indigo and show several morphological and genetic differences.

Environmental factors affecting productivity, indican content, and indigo yield in Polygonum tinctorium Ait., a subtropical crop grown under temperate conditions.

Polygonum tinctorium Ait. is a herbaceous subtropical annual plant, belonging to the family Polygonaceae. Within the cells of its leaves P.

Quantitative analysis of indigo and indigo precursors in leaves of Isatis spp. and Polygonum tinctorium.

Analysis of extracts from two woad species (Isatis tinctoria and Isatis indigotica) and Polygonum tinctorium revealed that only one indigo precursor (indican) was present in Polygonum, but two precursors were found in Isatis spp. This was done using high performance liquid chromatography (HPLC), coupled to an evaporative light scattering detector (ELSD). In Isatis spp.

A new HPLC-ELSD method to quantify indican in Polygonum tinctorium L. and to evaluate beta-glucosidase hydrolysis of indican for indigo production.

A method to quantify the indigo precursor indican (indoxyl-beta-D-glucoside) in Polygonum tinctorium L. has been developed. Plant material was extracted in deionized water, and indican was identified and quantified using high performance liquid chromatography (HPLC) coupled to an evaporative light scattering detector (ELSD).

Effects of gamma-irradiation on the free radical and antioxidant contents in nine aromatic herbs and spices.

Nine spice and aromatic herb samples (i.e., basil, bird pepper, black pepper, cinnamon, nutmeg, oregano, parsley, rosemary, and sage) were gamma-irradiated at a dose of 10 kGy according to commercial practices.
