    Abstract: Agriculture is often considered as one of the main threats to ecosystems. Unsustainable farming practices often result in habitat loss, inefficient use of water, soil degradation, pollution, genetic erosion, among other negative impacts on human life, including hunger, low food quality, reduced access to food resources, as well as the abandonment of rural areas. Nevertheless, when agriculture is practiced in a sustainable way, it can contribute to the preservation of many habitats, to the protection of watersheds, to the preservation and improvement of soil health. The use of sustainable and ecological practices is the key feature distinguishing traditional agriculture from intensive one. It may not provide very high yields, but ensures sustainable harvests over time, thanks to time-tested technologies and traditional know-hows and also represent examples of adaptation to harsh environmental conditions. Based on this approach, in 2002, FAO launched the concept of Globally Important Agricultural Heritage Systems (GIAHS) Programme, to identify and safeguard agricultural systems that are ensuring food and livelihood security, while maintaining magnificent landscapes, agricultural biodiversity, traditional knowledge, cultural and social values. This book presents 18 examples of these traditional agriculture systems around the world, with a special focus on Europe, Asia, Africa, Central and South America, as a result of the “GIAHS Building Capacity” project co-funded by the Italian Agency for Development Cooperation (AICS) and carried out by the Department of Agriculture, Food, Environment and Forestry (DAGRI) of the University of Florence (Italy).

    Description: The data products consist of four (4) global layers that include estimates of 1) growing stock volume (GSV, unit: m3/ha) for the year 2010 (raster dataset) Definition: volume of all living trees more than 10 cm in diameter at breast height measured over bark from ground or stump height to a top stem diameter of 0 cm. Excludes: smaller branches, twigs, foliage, flowers, seeds, stump and roots (definition of FAO). 2) per-pixel of growing stock volume uncertainty expressed as standard error in m3/ha (raster dataset) 3) above ground biomass (AGB, unit: tons/ha i.e., Mg/ha) for the year 2010 (raster dataset) Definition: the mass, expressed as oven-dry weight of the woody parts (stem, bark, branches and twigs) of all living trees excluding stump and roots. 4) per-pixel estimates of above-ground biomass uncertainty expressed as standard error in Mg/ha (raster dataset) The GSV estimates were obtained from spaceborne SAR (ALOS PALSAR, Envisat ASAR), optical (Landsat-7), LiDAR (ICESAT) and auxiliary datasets with multiple estimation procedures. AGB was obtained from GSV with a set of Biomass Expansion and Conversion Factors (BCEF) following approaches to extend on ground estimates of wood density and stem-to-total biomass expansion factors to obtain a global raster dataset. It is referred to the Algorithm Theoretical Basis Document for details on the EO datasets, the biomass retrieval algorithms and the estimation of the BCEF (see http://www.globbiomass.org) The GSV and AGB data are available in form of tiles of 40 deg x 40 deg from this repository as well as through http://globbiomass.org/products/global-mapping/. Technical specifications can be found in the README file (see Further details)

    Description: Nodularia spumigena is a toxic, filamentous cyanobacterium capable to fix atmospheric nitrogen, which is often dominating cyanobacterial bloom events in the Baltic Sea and other aquatic systems worldwide. Phosphate (P) limitation has been considered as one environmental parameter that is somehow promoting the establishment of cyanobacterial mass developments. In the present study, we analyzed the response of Nodularia spumigena strain CCY9914 towards strong phosphorus limitation in an experimental approach. Pre-experimental and experimental incubations were performed at the Department of Plant Physiology (University of Rostock, Germany). Specifically, cultures were incubated under P-replete and P-deplete conditions for 21 days. The P-replete medium was composed as follows: 33% ASNIII and 67% BG11 medium mixture (as described by Hagemann et al., 2019), with 0.02 g L-1 K2HPO4 in the modified ASNIII (Rippka et al., 1979) and 0.00078 mg L-1 K2HPO4 in BG11 medium modified with 20 mM TES buffer to pH 8 (Rippka et al., 1979). Conversely, the P-deplete medium did not contain any additional P. Samples were collected after 3 hours (day 0), 7, 14 and 21 days from the start of the experiment to assess the variation of the following physiological parameters: biomass increase estimated by dry weight measurements and polyphosphate accumulation measured according to Martin et al. (2014). Additionally, ortho-phosphate and ammonium concentrations were measured in the medium to assess nutrient conditions during the course of the experiment. The experiment was repeated two times. During the second iteration of the experiment, samples from d7 and d14 were used for differential gene expression analysis (RNA-seq data available on Gene Expression Omnibus (GEO) accession GSE213384).

    Description: Background: the Registro Italiano Trombocitemie (RIT) was activated mainly to evaluate the diagnosis and therapy appropriateness in the thrombocythemic patients with Ph-negative myeloproliferative neoplasm (MPN) observed in the adhering centers. Objective: to evaluate how the diagnostic and therapeutic approach changed in the RIT patients diagnosed with thrombocythemic MPN in the last two decades. Methods: the RIT centers registered by a web-based system during the years 2005-2014 their thrombocythemic MPN patients, and semesterly updated their follow-up data. For patients diagnosed before 2005, the data on diagnosis and prior follow-up were retrospectively collected. The diagnostic process and the initial treatment (started into the first year after diagnosis) were comparatively analyzed in the patients diagnosed before and after 2005. Results: the RIT centers registered 2629 patients. 2388 of them, object of this analysis, were diagnosed between1995 and 2014: 1098 (46%) in the decade 1995-2004 (Group I), and 1290 (54%) in the decade 2005-2014 (Group II). The diagnostic process in the patients of Group II and Group I included bone marrow biopsy (BMB, performed into 1 year and before any cytoreduction): 85% vs 80%, p

    Description: Background: Neurofibromatosis 1 (NF1) is an autosomal dominant genetic disorder. The expression of NF1 is extremely variable considering the broad spectrum of mutations affecting the gene(s) responsible for the pathology. Aim: To investigate the prevalence of oral manifestations in a group of children affected by neurofibromatosis type 1. Design: 100 pediatric patients, with genetically confirmed NF1 were enrolled in this study and matched to a total of 100 healthy children. Clinical examination was used to investigate: dental caries, dental abnormalities, periodontal health, neurofibromas, malocclusions, and enamel defects. Results: Mann Whitney’s test concerning prevalence of dental caries resulted in a no significant difference between the two groups (p = 0.90); a significant difference was highlighted as regards the other kinds of manifestations as well: enamel defects (p = 0.01), neurofibromas (p = 0.0043) and poor oral hygiene (p = 0.0002) with a higher prevalence of these features in NF1 patients than healthy controls. Similar results come out, regarding dental abnormalities in which can observe a significant difference between shape anomalies (p 〈 0.001). Conclusion: According to data obtained from the present study, it can be stated that NF1-related oral manifestations can be detected during childhood and adolescence. In particular for neurofibromas, enamel defects, shape anomalies, and poor oral hygiene.

    Description: Background. In patients with Ph-negative chronic myeloproliferative neoplasm (MPN) the molecular pattern, beside other characteristics at diagnosis, has been related to the disease prognosis. Aim. To compare clinical and biological features at diagnosis and during the follow-up in gender/age-matched MPN patients showing different molecular pattern. Material and methods. The Registro Italiano Trombocitemie (RIT) is a web-based registry that includes thrombocythemic MPN patients diagnosed according to PVSG or WHO criteria, registered after 2005, and then prospectically followed. The JAK2 V617F mutation (JAK2+) was reported in 941 (58.4%) out of 1610 tested patients. On the basis of subsequent tests, performed in part of the JAK2 WT (JAK2-) subjects, 103 patients were JAK2-/CALR+ (CALR+), 14 patients were JAK2-/CALR-/MPL+ (MPL+), and 46 were JAK2-/CALR-/MPL- (3NEG). The 103 CALR+ patients were compared with 309 (103 x 3) JAK2+ patients matched for gender, age, and revised diagnosis (WHO 2008 criteria). A similar comparison was done between 46 3NEG patients and other 138 (46 x 3) JAK2+ matched patients. Results. CALR+ and matched JAK2+ patients had, as expected, the same gender distribution (males 41%), the same median age (51 years), and no significant difference (p 0.42) in the WHO diagnosis distribution. CALR+ patients, as compared with JAK2+ patients, showed at diagnosis: higher median platelet (PLT) count (839 vs 718 x109/L, p
