Metabolomics approach to studying minimally processed peach (Prunus persica) fruit
2012
Fresh-cut fruit products for both retail and food service applications have increasingly appeared in the market place in recent years. Among different fruit types, peaches can be used and are highly appreciated as fresh-cut product although their commercial success is limited due to their short shelf-life and the quick onset of wounding-related physiological reactions. In this work we analyzed the technological and physiological changes induced by fresh-cut preparation in three different types of peach cultivars: 'Fayette' (melting), 'Wilhelmina' (non-melting) and 'Ghiaccio3' (stony hard). We performed a metabolite targeting profiling to focus on the changes in organic acid levels, importan…
Metabolites produced by agents of dieback of grapevine in Sicily: Lasiodiplodia mediterranea, Neofusicoccum parvum and N. vitifusiforme
2015
Botryosphaeria dieback was recently reported in West Sicilian vineyards. The disease complex was only associated with isolates of genus Lasiodiplodia in 2007 and together with Diplodia seriata, Neofusicoccum parvum and Neofusicoccum vitifusiforme, this latest reported for the first time on Vitis vinifera in Italy. Moreover, a representative isolate of each species was inoculated on green shoots and fulfilled Koch’s postulates, although the lengths of vascular discolourations were variable depending on the species. As well as the other GTD causal agents, the expression of foliar symptoms (pale colour along the margins and between veins) was also occasional in Sicily, it was hypothesized that…
Composition of mosses, their metabolites and environmental stress impacts
2018
Sūnas ir nozīmīga augu grupa ar plašu izplatību. Sūnu sastāva pētījumi ir kļuvuši aktuāli, ņemot vērā bioloģiski aktīvu savienojumu klātbūtni un augsto izturību pret vides apstākļu mainību. Promocijas darba mērķis ir analizēt sūnu sastāvu, to metabolītus un vides stresa ietekmes uz tiem. Veikta sūnu sekundāro metabolītu ekstrakcijas apstākļu izpēte, kas nodrošina liela skaita vielu identifikāciju. Sūnu lipīdi satur daudzas bioloģiski aktīvas vielas un veikta to aktivitātes izpēte. Sūnu sekundārie metabolīti uzrāda augstu antimikrobiālo aktivitāti un spējas inhibēt vairāku vēža šūnu līniju attīstību un līdz ar to satur perspektīvas vielu grupas izmantošanai biomedicīnā. Vides stresa ietekmes…
Wpływ czynników biotycznych i abiotycznych na wzrost i rozwój Dionaea muscipula oraz warunki prowadzenia hodowli
2018
W pracy przedstawiono sposób namnażania rośliny owadożernej z rodziny Droseraceae –Dionaea muscipula (Muchołówka amerykańska), występującej w środowisku naturalnym jedynie na terenach Karoliny Północnej oraz Karoliny Południowej oraz sposoby jej uprawy wpływające na jakość hodowli. Podstawowymi czynnikami są prawidłowe nasłonecznienie, nawodnienie, zapewnienie roślinie odpowiedniego podłoża, systematyczna pielęgnacja i prawidłowa temperatura otoczenia. Rośliny te nie wymagają nawożenia m.in. ze względu na umiejętność pozyskiwania składników ze schwytanych owadów. Pomimo faktu, że Dionaea muscipula jest gatunkiem monotypowym, powstało wiele różnorodnych kultywarów występujących w hodowlach n…
Six-Week Endurance Exercise Alters Gut Metagenome That Is not Reflected in Systemic Metabolism in Over-weight Women
2018
Recent studies suggest that exercise alters the gut microbiome. We determined whether six-weeks endurance exercise, without changing diet, affected the gut metagenome and systemic metabolites of overweight women. Previously sedentary overweight women (n = 19) underwent a six-weeks endurance exercise intervention, but two were excluded due to antibiotic therapy. The gut microbiota composition and functions were analyzed by 16S rRNA gene amplicon sequencing and metagenomics. Body composition was analyzed with DXA X-ray densitometer and serum metabolomics with NMR metabolomics. Total energy and energy-yielding nutrient intakes were analyzed from food records using Micro-Nutrica software. Serum…
