Aquatic Macrophytes Occurrence in Mediterranean Farm Ponds: Preliminary Investigations in North-Western Sicily (Italy)
2021
Mediterranean wetlands are severely affected by habitat degradation and related loss of biodiversity. In this scenario, the wide number of artificial farm ponds can play a significant role in the biodiversity conservation of aquatic flora. In the present contribution we show the preliminary results of a study on Mediterranean farm ponds of north-western Sicily (Italy), aimed to investigating the environmental factors linked to the occurrence of submerged macrophytes (vascular plants and charophytes). We studied the aquatic flora of 30 ponds and determined the chemical and isotopic composition of their water bodies on a subset of the most representative 10 sites. Results show that (1) farm p…
""Flora Italiana Digitale": an interactive identification tool for the Flora of Italy
2010
The digital facilities of the second edition of Pignatti's "Flora d'Italia" are presented. A software, called FID (i.e. "Flora Italiana Digitale") will link together a random-access interactive identification tool, a thesaurus, synoptic tables and one template for each single species, including a distribution map (referred to the Italian regions), "ecograms", a text-box and up to 24 high-resolution colour images. The FID follows a "shareware phylosophy". All contents and images can be integrated and/or replaced over time, in order to continuously improve the diagnostic and qualitative performance of the utilities provided. Ideally, the community of users should interact on the web, so that …
Impact of Oat-Based Products on Human Gastrointestinal Tract
2015
Abstract Oat is rich in valuable nutrients. In comparison to other cereals, oat contains more total proteins, carbohydrate, fat, non-starch fibre, as well as unique antioxidants (one of them - avenanthramides), vitamins, and minerals. One of the most often studied components of oats is β-glucan - a type of soluble dietary fibre located throughout the starch endosperm, but with highest concentration in the bran. Many studies have shown the beneficial health effects of oat β-glucan as a soluble dietary fibre. Until now, most of the studies on this nutrient have been conducted in the cardiovascular and diabetology field. This article aimed to review the literature on studies that investigated …
On flora semantics in house names found in Vidzeme: materials contained in the 1826 counting of souls in Vidzeme province
2014
On flora semantics in house names found in Vidzeme: materials contained in the 1826 counting of souls in Vidzeme province The information of the counting of souls containing both house names and names of individuals is an essential aspect of historical onomastics. The first counting of souls in Vidzeme took place in 1782 and coincided with the 4 th analogous census of the provinces of Russia. Subsequently these took place at irregular intervals, the 5 th in 1795, the 6 th in 1811, the 7 th in 1816, the 8 th in 1834, the 9 th in 1850, and the final, 10 th in 1858. The number of house names entered in the 1826 counting of souls in Vidzeme province (guberna) is 14,500, including those of peasa…
The Metabolic Sensor GPR43 Receptor Plays a Role in the Control of Klebsiella pneumoniae Infection in the Lung
2018
Pneumonia is one of the leading causes of death and mortality worldwide. The inflammatory responses that follow respiratory infections are protective leading to pathogen clearance but can also be deleterious if unregulated. The microbiota is known to be an important protective barrier against infections, mediating both direct inhibitory effects against the potential pathogen and also regulating the immune responses contributing to a proper clearance of the pathogen and return to homeostasis. GPR43 is one receptor for acetate, a microbiota metabolite shown to induce and to regulate important immune functions. Here, we addressed the role of GPR43 signaling during pulmonary bacterial infection…
Baseline Gut Microbiota Composition Is Associated With Schistosoma mansoni Infection Burden in Rodent Models
2020
In spite of growing evidence supporting the occurrence of complex interactions between Schistosoma and gut bacteria in mice and humans, no data is yet available on whether worm-mediated changes in microbiota composition are dependent on the baseline gut microbial profile of the vertebrate host. In addition, the impact of such changes on the susceptibility to, and pathophysiology of, schistosomiasis remains largely unexplored. In this study, mice colonized with gut microbial populations from a human donor (HMA mice), as well as microbiota-wild type (WT) animals, were infected with Schistosoma mansoni, and alterations of their gut microbial profiles at 50 days post-infection were compared to …
Metabolomics as a Promising Resource Identifying Potential Biomarkers for Inflammatory Bowel Disease
2021
Inflammatory bowel disease (IBD) is a relapsing chronic disorder of the gastrointestinal tract characterized by disruption of epithelial barrier function and excessive immune response to gut microbiota. The lack of biomarkers providing early diagnosis or defining the status of the pathology difficulties an accurate assessment of the disease. Given the different metabolomic profiles observed in IBD patients, metabolomics may reveal prime candidates to be studied, which may help in understanding the pathology and identifying novel therapeutic targets. In this review, we summarize the most current advances describing the promising metabolites such as lipids or amino acids found through untarge…
Valencians als Jocs Florals de Barcelona (1862-1893)
2012
Durant els anys 1862 i 1893 la presència i participació d’escriptors valencians en els certàmens coneguts amb el nom de Jocs Florals de Barcelona va ser notable. I també molt significativa, ja que sovint es produí a conseqüència de la invitació que els feien els germans catalans a ser membres del consistori de mantenidors. Una invitació que cal interpretar en termes de reconeixement, esperó i ajut, i que els valencians acceptaren de bon grat i reiteradament. Cosa que permeté que, literàriament parlant, pel consistori de mantenidors dels Jocs Florals de Barcelona passara el bo i millor, literàriament parlant, del segle XIX valencià. El present estudi repassa, detalla i valora quina fou aquel…
