    Kauran idätyksessä on itua

    Idätys muokkaa kauran rakennetta. Sen avulla voidaan myös tuottaa jyvään tai hajottaa siitä haluttuja yhdisteitä. Idätys ja sitä seuraavat kuumennuskäsittelyt antavat kauraan väriä, makua ja rapeutta. Samalla paranee myös kauran säilyvyys. Idätys lisää huomattavasti myös bioaktiivisten yhdisteiden määrää kaurassa ilman, että arvokkaan kuidun määrä kuitenkaan huomattavasti vähenisi.vo

    In the information era at this time all humankind in each aspect of his life expect a fast and exact service both in the healthy situation and the situation to be sick. Likewise his matter with that is hop for by all the elements of the framer of the system in the Pancoranmas community health centre, the patient 's satisfaction is not enough only well not him the community health centre, professional him the doctor along with medical him, but also depend from fast and to be precise the information service that is need by the patient. By using aids of the system plan, then is develop by an information system so as facilitat in the matter kept, modified, process and access the data in accordance with the requirement, from this system it is hop time that is us to access the data like the patient 's data, medicine, the story of the health of the patient could be more fast, efficient and safe in his storage and accurate, with the availability of quality information and the good communications network interdepartmental will increase the productivity of his officials, this plan of the information system if being us is the opportunity for the community health centre to increase the service and professionalism.Keyword(s) : information system, puskesmas, spiral, water-fallSubject description: K.6.Management of Computing and Information | K.6.3.

    Raspberry Ketone Accumulation in Nicotiana benthamiana and Saccharomyces cerevisiae by Expression of Fused Pathway Genes

    Get PDF
    Raspberry ketone has generated interest in recent years both as a flavor agent and as a health promoting supplement. Raspberry ketone can be synthesized chemically, but the value of a natural nonsynthetic product is among the most valuable flavor compounds on the market. Coumaroyl-coenzyme A (CoA) is the direct precursor for raspberry ketone but also an essential precursor for flavonoid and lignin biosynthesis in plants and therefore highly regulated. The synthetic fusion of 4-coumaric acid ligase (4CL) and benzalacetone synthase (BAS) enables the channeling of coumaroyl-CoA from the ligase to the synthase, proving to be a powerful tool in the production of raspberry ketone in both N. benthamiana and S. cerevisiae. To the best of our knowledge, the key pathway genes for raspberry ketone formation are transiently expressed in N. benthamiana for the first time in this study, producing over 30 ÎĽg/g of the compound. Our raspberry ketone producing yeast strains yielded up to 60 mg/L, which is the highest ever reported in yeast

    Methyljasmonate Elicitation Increases Terpenoid Indole Alkaloid Accumulation in Rhazya stricta Hairy Root Cultures

    Methyl jasmonate is capable of initiating or improving the biosynthesis of secondary metabolites in plants and therefore has opened up a concept for the biosynthesis of valuable constituents. In this study, the effect of different doses of methyl jasmonate (MeJA) elicitation on the accumulation of terpenoid indole alkaloids (TIAs) in the hairy root cultures of the medicinal plant, Rhazya stricta throughout a time course (one-seven days) was investigated. Gas chromatography-mass spectrometry (GC-MS) analyses were carried out for targeted ten major non-polar alkaloids. Furthermore, overall alterations in metabolite contents in elicited and control cultures were investigated applying proton nuclear magnetic resonance (H-1 NMR) spectroscopy. Methyl jasmonate caused dosage- and time course-dependent significant rise in the accumulation of TIAs as determined by GC-MS. The contents of seven alkaloids including eburenine, quebrachamine, fluorocarpamine, pleiocarpamine, tubotaiwine, tetrahydroalstonine, and ajmalicine increased compared to non-elicited cultures. However, MeJA-elicitation did not induce the accumulation of vincanine, yohimbine (isomer II), and vallesiachotamine. Furthermore, principal component analysis (PCA) of H-1 NMR metabolic profiles revealed a discrimination between elicited hairy roots and control cultures with significant increase in total vindoline-type alkaloid content and elevated levels of organic and amino acids. In addition, elicited and control samples had different sugar and fatty acid profiles, suggesting that MeJA also influences the primary metabolism of R. stricta hairy roots. It is evident that methyl jasmonate is applicable for elevating alkaloid accumulation in "hairy root" organ cultures of R. strica.Peer reviewe

Furthermore, overall alterations in metabolite contents in elicited and control cultures were investigated applying proton nuclear magnetic resonance (1H NMR) spectroscopy. Methyl jasmonate caused dosage- and time course-dependent significant rise in the accumulation of TIAs as determined by GC-MS. The contents of seven alkaloids including eburenine, quebrachamine, fluorocarpamine, pleiocarpamine, tubotaiwine, tetrahydroalstonine, and ajmalicine increased compared to non-elicited cultures.
