Lemon post-harvest decay control by natural products

2008

Postharvest diseases of lemon fruits represent one of the most severe sources of loss production. They are controlled by imazalil (IMZ), thiabendazole (TBZ) and sodium ortho-phenil-phenate (SOPP) registered fungicides for postharvest treatments. Nowadays, the chemical use is becoming more restricted for environmental concerns and development of fungicide-tolerance strains of fungal pathogens. In the last few years a renewed interest in alternative methods of postharvest decay control has been increasing and the research for natural products has provided encouraging results. The aim of this research has been the in vitro and in vivo effectiveness evaluation of six essences (garlic, cloves, o…

Fiktiivisen tekijähahmon roolit ja leikki maailmojen välisellä rajalla Lemony Snicketin Surkeiden sattumusten sarjassa : "Valitettavasti minun täytyy…

2017

Tarkastelen tutkielmassani Surkeiden sattumusten sarja -nimisen lastenkirjasarjan fiktiivisen tekijähahmon, Lemony Snicketin, rooleja sarjan maailman rakentumisen näkökulmasta. Niin Snicket kuin sarjakin ovat Daniel Handler -nimisen materiaalisen tekijän tuotosta, mutta itse kirjoista tämä ei käy ilmi. Snicket ei kuitenkaan ole vain Handlerin salanimi vaan myös kirjojen kertoja ja henkilöhahmo niiden maailmassa. Sarjan annetaan ymmärtää perustuvan Snicketin tutkimustyölle: kirjat ovat fiktiivisiä tutkimusraportteja kolmen orpolapsen epäonnisesta elämästä. Snicket siis on paitsi kertoja myös fiktiivinen tutkija. Tutkimuskysymyksiäni ovat, kuinka Snicketin toiminta kertojana ja tutkijana rake…

Control of Portulaca oleracea by boldo and lemon essential oils in different soils

2015

Soil characteristics influence plant growth and can affect the phytotoxicity of the essential oils. In this study chemical composition and herbicidal activity of Peumus boldus Mol. and lemon essential oils in different growing medium against Portulaca oleracea L. was investigated. Ninety-four compounds accounting between 95.5 and 99.8% of the total essential oil were identified by gas chromatography-mass spectrometry in boldo and lemon essential oils. Ascaridole (31.56. ±. 0.15%), p-cymene (21.58. ±. 0.09%) and 1,8-cineole (12.57. ±. 0.13%) were the main compounds in P. boldus whereas large amount of limonene (59.28%) followed of β-pinene (12.96%) and γ-terpinene (10.92%) were found in lemo…

Ambulatory blood pressure and arterial stiffness web-based telemonitoring in patients at cardiovascular risk. First results of the VASOTENS (Vascular…

2019

The VASOTENS Registry is an international telehealth-based repository of 24-hour ambulatory blood pressure monitorings (ABPM) obtained through an oscillometric upper-arm BP monitor allowing combined estimation of some vascular biomarkers. The present paper reports the results obtained in 1200 participants according to different categories of CV risk. Individual readings were averaged for each recording and 24-hour mean of brachial and aortic systolic (SBP) and diastolic blood pressure (DBP), pulse wave velocity (PWV), and augmentation index (AIx) obtained. Peripheral and central BP, PWV and AIx values were increased in older participants (SBP only) and in case of hypertension (SBP and DBP).…

Comparison of the Fungistatic Activity of Selected Essential Oils Relative to

2018

The aim of the study was to determine the chemical composition of lemon, rosewood, geranium and rosemary oils, and compare their effect on the sensitivity of Fusarium graminearum ZALF 24 and Fusarium graminearum ZALF 339 isolated from infected cereals. The tested oils were added to Potato Dextrose Agar (PDA) medium at concentrations of 0.125%, 0.25%, 0.5%, 1.0% and 2.0%. The activity of the oils on inhibition of the linear growth of mycelium was evaluated by measuring the growth of fungal colonies (growth index), while the fungistatic activity was evaluated on the basis of the percentage growth inhibition of a fungal colony and calculated according to Abbott’s formula. The sensitivity of th…

Economic and Technical Feasibility of Betanin and Pectin Extraction from Opuntia ficus-indica Peel via Microwave-Assisted Hydrodiffusion

2019

Investigating the feasibility of betanin and pectin extraction from Opuntia ficus-indica peel via microwave-assisted hydrodiffusion and gravity, this study identifies selected important economic and technical aspects associated with this innovative production route starting from prickly pear fruit discards. Which benefits would be derived from this process? Would production be limited to Opuntia-growing countries or, likewise to what happens with dried lemon peel chiefly imported from Argentina, would production take place abroad also? Can distributed manufacturing based on clean extraction technology compete with centralized production using conventional chemical processes?

Economic and Financial Comparison between Organic and Conventional Farming in Sicilian Lemon Orchards

2015

Sicily has a long tradition in citrus fruit cultivations that with vineyard and olive tree represent the main Mediterranean tree crops. In this paper we have evaluated the economic and financial sustainability of lemon production, both in organic farming and in conventional farming

Molecular diagnostic tools for the detection and characterization of Phoma tracheiphila

2011

In the recent years PCR-based techniques for the identification and detection of Phoma tracheiphila, the causal agent of citrus mal secco disease, have been evaluated aiming to provide tools for biological and epidemiological studies. A wide collection of P. tracheiphila strains was used to evaluate and validate diagnostic protocols and a fAFLP method for fungal characterization. Conventional and real-time PCR protocols were successfully tested for the specific identification of P. tracheiphila and its detection in planta. A further improvement of the real-time PCR protocol and the DNA extraction methods allowed the quantification of the fungus both from naturally infected and artificially …

2020

The present study aimed at measuring the levels of legacy and emerging contaminants in fillet samples from four demersal fish caught in two fishing sites from Southern Norway, in order to assess possible implications for food safety. Levels of organochlorine compounds (OCs), organophosphate pesticides (OPs), polychlorinated biphenyls (PCBs), polybromodiphenyl ethers (PBDE), per- and polyfluoroalkyl substances (PFASs), and polycyclic aromatic hydrocarbons (PAHs) were measured in fillet from Atlantic cod (Gadus morhua), European plaice (Pleuronectes platessa), lemon sole (Microstomus kitt), and European flounder (Platichthys flesus) specimens. A negligible contamination by all the investigate…
