The ‘recent’ forests of Mount Venda (Padua, Italy): when historical cartography and archaeobotany tell quite a different story

2018

Forests, like agricultural systems and housing, are an integral part of the human landscapes. They evolve over time, not only in response to environmental factors (e.g. climate change) but also in response to developments in human society. This work on the analysis of forest dynamics in Euganean hills is the result of research carried out as part of the research programmes THISTLE (MSCA Fellowship, grant agreement: 656397) and MEMOLA (EU FP7 Project , grant agreement: 613265). The work is focused on two mountains in particular: Monte Venda and Monte della Madonna. The archaeobotanical investigations reveal the presence of ancient forests (since the 14th century) in these areas , although th…

Taxonomic notes and critical discussion on the status of Hydnum notarisii (Basidiomycota) through the evaluation of Giuseppe Inzenga's original study…

2016

The current taxonomic status of Hydnum notarisii Inzenga is here critically analyzed on the basis of Giuseppe Inzenga’s original description and of the specimens kept in his private herbarium hosted in the Istituto Agrario Castelnuovo (Palermo, Italy) and in the Herbarium of Museum of Evolution, Uppsala University, Sweden (UPS). The detailed morphological study of the original dried material through the use of compound optical and scanning electron microscopy demonstrated that this particular fungus possesses very similar features with Hericium erinaceus (Bull.)

The Nonvolatile and Volatile Metabolites of Prangos ferulacea and Their Biological Properties

2019

Abstract Prangos ferulacea (L.) Lindl. (Fam. Apiaceae), an orophilous species of eastern Mediterranean and western Asia, possesses a number of biological properties that are worthy of exploitation in different fields. Phytochemical investigations revealed the presence of coumarins, prenyl-coumarins, and furano-coumarins as the main constituents of this species, as well as several flavonoids. Among prenyl-coumarins, osthol is a promising apoptotic agent quite selective toward cancer cells. In addition, the essential oils have been extensively investigated, and several chemotypes have been identified. This work reviews the literature on this species published between 1965 and 2018, describes …

Medicinal Mushrooms: Bioactive Compounds, Use, and Clinical Trials

2021

Medicinal mushrooms have important health benefits and exhibit a broad spectrum of pharmacological activities, including antiallergic, antibacterial, antifungal, anti-inflammatory, antioxidative, antiviral, cytotoxic, immunomodulating, antidepressive, antihyperlipidemic, antidiabetic, digestive, hepatoprotective, neuroprotective, nephroprotective, osteoprotective, and hypotensive activities. The growing interest in mycotherapy requires a strong commitment from the scientific community to expand clinical trials and to propose supplements of safe origin and genetic purity. Bioactive compounds of selected medicinal mushrooms and their effects and mechanisms in in vitro and in vivo clinical stu…

BIOACTIVE MOLECULES FROM MARINE INVERTEBRATE ORGANISMS AS POTENTIAL TOOLS IN RESTORATION PROCEDURES

2013

In the last decades molecular biology has provided innovative approaches in order to set up specific protocols for the conservation and restoration of cultural assets. In this study, which falls within the so called field of Blue-biotechnology, new bio-reactive peptides isolated from marine invertebrate organisrns (Cnidaria and Molluscs) were tested aim to bio-cleaning (proteolytic- peptides) the surfaces or to control (antimicrobial-peptides) the colonization of historic-artistic manufacts by fungi or bacteria. Particularly, the proteolytic-peptides showed hydrolytic activity, specific for animal-glue, in a range of temperatures of 4-37°C; than acting without heating the surface, by a cont…

Archeobotanical study of traditional agroecosystems based on SEM-EDX analysis of buried phytoliths

2015

The FP7 Project "MEditerranean MOntainous LAndscapes: an historical approach to cultural heritage based on traditional agrosystems (MEMOLA)" (http://www.memolaproject.eu/it) is studying past landscapes using ancient soil horizons as archaeological records. The project aims at evaluating the biodiversity of no longer existing environments, in order to reconstruct the past agroecosystems. One of the approach used in the study consisted in the selective sampling of buried paleo-soil horizons for the search of “testimonials” or useful pedo-archaeological "indicators" that can tell something about past environments and peculiar ecosystems no longer present. To this purpose it was decided to star…

Marine organisms as source of bioactive molecules applied in restoration projects

2015

Abstract In recent decades research in the conservation and restoration field has provided sustainable alternatives to traditional procedures for cleaning or controlling the microbial colonization of works of art. In the present study, for the first time novel bioactive molecules extracted from marine invertebrate organisms (Anthozoa) were tested instead of chemical compounds for removing protein layers or as a biocide for controlling fungal or bacterial colonization. In particular, Bioactive Molecules with Protease activity (BMP), acting in a temperature range of 4- 30°C, were tested for the hydrolysis of protein layers on laboratory specimens. The cleaning protocol provides a selective pr…

Conflicting needs of the thermal indoor environment of museums: In search of a practical compromise

2008

Thermal indoor microclimate conditions in museum buildings refer to two important requirements: the preservation of works of art and the comfort of visitors to these buildings and/or those working inside them. Unfortunately, different works of art have different internal parameters which render the management and control of the indoor thermal microclimate difficult. In this work the values proposed by various standards for the thermal environment of museum buildings have been revised. Moreover, the indoor microclimatic conditions relating to people's comfort have been described, with the aim of singling out possible common ranges for these parameters. With this aim, a useful simultaneousnes…
