BACKGROUND Chemoprevention represents the possibility to prevent, stop or reverse the cancerogenetic process. In this context the interest towards natural extracts and botanical drugs has constantly grown due to their phytochemical content. Castanea sativa Mill. (CSM) extracts showed to exert positive effect in the prevention/counteraction of chronic/degenerative diseases, therefore, we evaluat...

Chestnut shells (CS) are an agronomic waste generated from the peeling process of the chestnut fruit, which contain 2.7–5.2% (w/w) phenolic compounds and approximately 36% (w/w) polysaccharides. In contrast with current shell waste burning practices, this study proposes a CS biorefinery that integrates biomass pretreatment, recovery of bioactive molecules, and bioconversion of the lignocellulos...

The aims of the study were to analyse characteristics of the Castanea airborne pollen and to compare aeropalynological data obtained from two sampling stations in north-west Croatia. The study was conducted in Zagreb and Samobor during the 2003-2006 periods, using the seven-day volumetric samplers of the Hirst design. In both study areas, the seasons of chestnut pollination were similar and las...

The current study evaluates the Pulsed Electric Field (PEF) technique for extraction of polyphenols from plants Rosa canina, Calendulaofficinalis and Castanea sativa. These are traditionally used both preparation therapeutic decoctions aromatization beverages (alcoholic or not). Pulses 10 ?s duration were to apply electric field intensities ranging 1.2 2.0 kV cm?1. period phenomenon was set 1 m...

Abstract Chestnut rot caused by Gnomoniopsis smithogilvyi is considered a severe threat to the production of chestnuts from European chestnut ( Castanea sativa Mill.) in Australia and overseas. Currently, most control strategies are applied post-harvest little known about use fungicides reduce nut infection orchards early season. This research evaluated effectiveness various against pathogen vi...

Understanding the adaptive mechanisms of forest species is vital to ensure their survival in a climate change scenario. This study aimed at uncovering relationship between genetic variability and environmental variables natural Castanea sativa populations, unveiling how different scenarios drove local adaption processes using landscape genomics approach. Our findings provide useful data for fut...

Chestnuts were collected either every 7 days from suspended nets used to intercept the fruits, every 2 days from the ground or every 7 days from the ground. Nuts were visually inspected after collection for the presence of exit holes of the chestnut weevil (Curculio elephas) and the chestnut moth (Cydia splendana), and 20 nuts per sampling and tree were bisected to assess fungal colonization. A...

Since the first description of cellular autofluorescence over a century ago, we have now come to appreciate that autofluorescence should not be discarded as a biological artifact but embraced as a biological phenomenon with potentially important cellular relevance. Indeed, cellular and tissue autofluorescence has been attributed to a spectrum of unrelated molecules such as porphyrins, vitamins ...
