1. Artichoke tuber tissue contained RNA polymerase activity bound to the chromatin and in the supernatant after chromatin sedimentation. 2. The activity in the supernatant, the soluble polymerase, was fractionated into polymerases I and II by DEAE-cellulose chromatography, and the properties of each activity were determined. 3. The proportions of chromatin-bound and soluble activities varied wi...

Artichoke (Cynara cardunculus L. var. scolymus (L.) Fiori) is a perennial plant of the Asteraceae’s family native to Mediterranean basin. Italy has rich artichoke biodiversity, but many landraces are subjected genetic erosion caused by increasing use commercial varieties that more homogenous in production. An Apulian landrace ‘Troianella’ was established vitro valorize and provide high-quality ...

Background: During treatment, many drugs may become cause of cardiac system toxicity, cytotoxic therapy including 5- Fluorouracil (5- FU). It is regarded as antimetabolite which its toxic effects during S phase the cell cycle and got activation by conversion thymidine phosphorylase into fluorodeoxyuridylate (5 fluoro 2'deoxyuridine 5'monophosphate, 5-FdUMP) inhibition thymidylate synthase, ulti...

Sugar beet (Beta vulgaris L.) leaves contain virus-inducible type 1 (single chain) ribosome-inactivating proteins that have been named beetins. The structural and functional characterization, the cellular location, and the potential role of beetins as antiviral agents are reported here. Beetins are formed of a single polypeptide chain with a varying degree of glycosylation and strongly inhibite...

Commercial niobium and synthesized zirconium phosphates were tested as water-tolerant heterogeneous acid catalysts in the hydrothermal conversion of different bio-based substrates. Different acid-catalyzed reactions performed using biomass-derived model compounds more complex real lignocellulosic biomasses substrate. The glucose cellulose was preliminarily investigated. Then, a wide plethora ra...

Objective: Germination is one of the most important stages of plants growth that affected by environmental stresses, especially drought and salinity. Methods: In order to study of Artichoke germination under different levels of salinity and drought, two separate experiments were performed. The four levels of salinity by NaCl (0, 50, 100, 150 mM) with three replications and five levels of drough...

UNLABELLED BACKGROUNG/AIM: Since combining conventional drugs with herbal medicinal products is in current research focus and possible of great interest as therapy improvement way, the aim of this study was to determine the effects of well-established antiatherosclerotic drug atorvastatin (CAS number 134523-00-5) and commercially available artichoke leaf tincture (ALTINC), used as combined ther...

BACKGROUND/OBJECTIVES Jerusalem artichoke has inhibitory activity against α-glucosidase and decreases fasting serum glucose levels, which may be related to its fructan content. The biological activity of fructan can be influenced by the degree of polymerization. Thus, in this study, the inhibitory effects of original and fermented purple Jerusalem artichoke (PJA) on α-glucosidase were compared ...
