“We Became Rich and We Lost Everything”: Ethnobotany of Remote Mountain Villages of Abruzzo and Molise, Central Italy

Profound socioeconomic changes affected mountains of Central Italy during the last century and many traditional agro-pastoral activities were abandoned. A few ethnobotanical studies in this area have specifically documented local wild plants used decades ago, but without analyzing in-depth how and why Traditional Ecological Knowledge (TEK) has eroded or changed over time. In this study, we 1) document ethnobotanical uses of four high-altitude remote villages of Central Italy, 2) discuss how these uses have changed over time, comparing them with fieldwork that was conducted 40 years earlier; and 3) assess how plant uses have changed across space, particularly whether the remoteness of villages or the occurrence of Sacred Natural Sites (SNS) have affected TEK linked to wild plants. Sixty semi-structured interviews revealed the use of 83 taxa belonging to 35 families. We did not find any relationship between SNS and the richness of TEK, as these SNS were not inhabited by monastic communities that could have shared their scholarly knowledge. There was not a relationship between remoteness and richness of TEK. The common statement emerging from the field, “We became rich and lost everything”, revealed how socio-economic changes resulted in the rapid abandonment of traditional practices, while the ubiquity of pharmacies may have contributed to the erosion of ethnomedicinal knowledge

Scholarly vs. Traditional Knowledge: Effects of Sacred Natural Sites on Ethnobotanical Practices in Tuscany, Central Italy

Sacred Natural Sites (SNSs), found in all inhabited continents, are cultural landscapes of spiritual significance for local communities. As they are believed to influence Traditional Ecological Knowledge (TEK), we documented the use of wild and semi-domesticated plants for food and medicine in four villages located at different distances from SNSs in Central Italy. Results may indicate that SNSs, which have been managed and inhabited for centuries by monastic communities, have had a restrictive impact on local TEK, as the communities located near SNSs reported fewer traditional uses for plants than those living further from the same SNSs. One possible explanation is that the Scholarly Knowledge (SK) held by the monastic communities of SNSs competed with the TEK of the surrounding villages and this resulted in a smaller body of plant-related folk knowledge, practices and beliefs retained by the people living in the vicinity of SNSs. Further studies should address the past and current mechanisms of competition and/or osmosis between TEK and SK in terms of both daily practices and beliefs/theoretical knowledge

Blended divergences: local food and medicinal plant uses among Arbëreshë, Occitans, and autochthonous Calabrians living in Calabria, Southern Italy

A study focusing on traditional uses of wild plants for gastronomic and medicinal purposes was carried out among three linguistic communities in Calabria, southern Italy. Ninety interviews with local elderly informants were conducted among Occitans and Arbëreshë, two linguistic minorities, and the dominant culture of autochthonous Calabrians. We recorded 85 taxa belonging to 39 botanical families and 66 different detailed use-reports including 35 culinary and 31 medicinal uses. Our overall data show the permanence of traditional ecological knowledge related to wild and semi-domesticated food and medicinal plants; however, high similarity indices among the three communities demonstrate that traditional ecological knowledge is following the pathway of homogenization and standardization toward the dominant culture, facilitated by a context of linguistic erosion, limited intergenerational transmission, and a centuries-old diffusion with Calabrian culture. Moreover, our study calls for further field surveys in isolated areas of Calabria to analyze how traditional ecological practices can be key tools in the development of local small-scale economies through the promotion of artisanal food entrepreneurship of wild food plant transformation

Characterization of Fungal Melanins from Black Stains on Paper Artefacts

This work was supported by Portuguese funds from FCT/MCTES through the CleanART research project (PTDC/EPH-PAT/0224/2014); the Associate Laboratory for Green Chemistry— LAQV (UIDB/50006/2020 and UIDP/50006/2020); the i3N Associate Laboratory and PTNMR (POCI01-0145-FEDER-007688; UIDB/50025/2020-2023, ROTEIRO/0031/2013–PINFRA/22161/2016); the iMed.ULisboa (UIDB/04138/2020), the fellowship number SFRH/BD/133447/2017 (T.G.P.) and the researcher contracts CEECIND/01474/2018 (S.O.S.) and 2021.03255.CEECIND (M.C.C).Melanins play a fundamental role in the biology and ecology of several fungal species. Unfortunately, this group of amorphous macromolecules also severely (and most times irreversibly) stains cultural heritage objects. Despite efforts made throughout the years, knowledge of the chemical composition and structure of melanins is still insufficient, which hampers the task of safely cleaning these colourants from cultural heritage materials in a targeted way without causing further deterioration. This work aimed therefore to contribute towards enlightening the characteristics of fungal melanins from three fungi that are common paper colonizers: Aspergillus niger, Chaetomium globosum and Cladosporium cladosporioides. The extracted melanins were characterized by FTIR, Raman, UV-vis, Solid-State NMR and MALDI-TOF MS spectroscopies and the effect of inhibitors of DHN-melanin and DOPA-melanin pathways on colony pigmentation and growth was evaluated. Although all the extracted colourants show a predominantly aromatic structure with carbonyl and phenolic groups, some differences between the melanins can be highlighted. Melanins obtained from Ch. globosum and Cl. cladosporioides exhibited similar structures and composition and both presented DHN-melanin characteristics, while A. niger’s melanins revealed a more complex and ordered structure, with a higher prevalence of highly conjugated carbonyls than the others, besides the additional presence of a yellow/green component. These conclusions cannot be overlooked while selecting targeted cleaning methodologies for melanin stains on cultural heritage materials.publishersversionpublishe

Genome-Wide DNA Methylation and Gene Expression Profiles in Cows Subjected to Different Stress Level as Assessed by Cortisol in Milk

Dairy cattle health, wellbeing and productivity are deeply affected by stress. Its influence on metabolism and immune response is well known, but the underlying epigenetic mechanisms require further investigation. In this study, we compared DNA methylation and gene expression signatures between two dairy cattle populations falling in the high- and low-variant tails of the distribution of milk cortisol concentration (MC), a neuroendocrine marker of stress in dairy cows. Reduced Representation Bisulfite Sequencing was used to obtain a methylation map from blood samples of these animals. The high and low groups exhibited similar amounts of methylated CpGs, while we found differences among non-CpG sites. Significant methylation changes were detected in 248 genes. We also identified significant fold differences in the expression of 324 genes. KEGG and Gene Ontology (GO) analysis showed that genes of both groups act together in several pathways, such as nervous system activity, immune regulatory functions and glucocorticoid metabolism. These preliminary results suggest that, in livestock, cortisol secretion could act as a trigger for epigenetic regulation and that peripheral changes in methylation can provide an insight into central nervous system functions

Fine mapping of loci on BTA8 associated to antibody response to Mycobacterium avium paratuberculosis in cattle

Paratuberculosis (ParaTB) or Johne's disease, caused by Mycobacterium avium subspecies paratuberculosis commonly known as MAP in cattle, is a chronic gastroenteritis characterized by diarrhoea, decreased milk production and ultimately death. MAP is responsible for huge economic losses, particularly in dairy cattle herds. Susceptibility to MAP infection has been found to be heritable with heritability estimates ranging from 0.06 to 0.102. The definition of an infected animal can be based either on the presence of anti-MAP antibodies in the serum, or by direct demonstration of MAP in tissue or faeces by culture or PCR. Several studies have addressed the identification of genetic loci associated with MAP susceptibility. The objective of this study was to refine a locus associated with antibody response to Mycobacterium avium paratuberculosi (MAP). Using a genome- wide association analysis, a single nucleotide polymorphism on Bos taurus autosome BTA8 namely the SNP rs43161947 at posi- tion 35398490 with a p-value of 7.02 e-05, has previously been identified by the authors as associated with MAP infection. Fine mapping of the region was conducted with 100 single nucleotide polymorphisms spanning a region between BTA8: 34422912 and BTA8: 364553881 covering 2 Mega bases (Mb) designed in to cover 1 Mb ahead and after the SNP identified on BTA8. The 2 Mb region on BTA8 was evaluated within a group of 966 Holstein cows collected from routine ParaTB screening in the province of Lodi in Italy, in an area with a high prevalence of ParaTB. Animals were defined as ParaTB positive based on the detection of serum antibodies produced in response to MAP infection using the ID-screen\uae ELISA test (ID VET Montpellier, France). Of the 966 samples, 483 were MAP antibody positive (cases) and 483 MAP antibody negative (MAP negative controls). All animals were female, and cases and MAP negative controls were from the same farm tested on the same day.Using a single marker associ- ation analysis, conducted within the R statistical environment, we identified 3 different QTLs within the 2 Mega base region, under the main QTL on BTA8 associated with antibody response to MAP, in position 34.700.000, 35.800.000 and 36.400.000 bp. This reveals the complexity of the genetic architecture of thetrait and confirms the need to further explore the genome with fine mapping approaches, or by the use of whole genome sequencing to investigate complex traits, such as disease resistance

Molecular Interactions in Ionic Liquids: The NMR Contribution towards Tailored Solvents

Ionic liquids have been on the spotlight of chemical research field in the last decades. Their physical properties (low vapor pressure, thermal stability, and conductivity) and the possibility of fine tuning make them a versatile class of compounds for a wide range of applications, such as catalysis, energy, and material sciences. Ionic liquids can establish multiple intermolecular interactions with solutes such as electrostatic, van der Waals, or hydrogen bonds. The prospect of designing ionic liquid structures toward specific applications has attracted the attention to these alternative solvents. However, their rational design demands a molecular detailed view, and Nuclear Magnetic Resonance is a unique and privileged technique for this purpose, as it provides atomic resolution and at the same time enables the study of dynamic information. In this chapter, we provide an overview about the application of Nuclear Magnetic Resonance spectroscopy techniques as a methodology for the rational design of ionic liquids as solvents for small organic compounds, CO2 capture, and polymers such as cellulose focusing mainly in the last 10 years

Distributed Computing Grid Experiences in CMS

The CMS experiment is currently developing a computing system capable of serving, processing and archiving the large number of events that will be generated when the CMS detector starts taking data. During 2004 CMS undertook a large scale data challenge to demonstrate the ability of the CMS computing system to cope with a sustained data-taking rate equivalent to 25% of startup rate. Its goals were: to run CMS event reconstruction at CERN for a sustained period at 25 Hz input rate; to distribute the data to several regional centers; and enable data access at those centers for analysis. Grid middleware was utilized to help complete all aspects of the challenge. To continue to provide scalable access from anywhere in the world to the data, CMS is developing a layer of software that uses Grid tools to gain access to data and resources, and that aims to provide physicists with a user friendly interface for submitting their analysis jobs. This paper describes the data challenge experience with Grid infrastructure and the current development of the CMS analysis system

Community singing, wellbeing and older people: implementing and evaluating an English singing tool for health intervention in Rome

Aim: The aim of this research was to explore the transferability and effectiveness of the English Silver Song Clubs model for older people in a different social and cultural context, i.e. in the capital city of Italy, Rome. Methods: A single condition, pre-test, post-test design was implemented. Participants completed two questionnaires: EQ-5D and York SF-12. Results: After the singing experience, participants showed a decrease in their levels of anxiety and depression. An improvement was also found from baseline to follow up in reported performance of usual activities. The English study showed a difference between the singing and non-singing groups at three and six months on mental health, and after three months on specific anxiety and depression measures. The current (Rome) study shows similar findings with an improvement on specific anxiety and depression items. Conclusions: Policy makers in different national contexts should consider social singing activities to promote the health and wellbeing of older adults as they are inexpensive to run and have been shown to be enjoyable and effective

Loco-regional adjuvant radiation therapy in breast cancer patients with positive axillary lymph-nodes at diagnosis (CN2) undergoing preoperative chemotherapy and with complete pathological lymph-nodes response. Development of GRADE (Grades of recommendation, assessment, Development and Evaluation) recommendation by the Italian Association of radiation therapy and Clinical Oncology (AIRO)

Objective: To perform a meta-analysis to determine the effect of loco-regional radiation therapy (RT) compared to no loco-regional RT for operated patients in clinical stage cN2 breast cancer at diagnosis and ypN0 after preoperative chemotherapy (PST). Material and Methods: Eligible studies were identified through a systematic search of the medical literature performed independently by two researchers using a validated search strategy. An electronic search of Medline via PubMed and Embase (Breast cancer AND preoperative chemotherapy AND radiation therapy) was conducted with no language or publication status restrictions. The effect of loco-regional RT on overall (OS), disease free (DFS), loco-regional recurrence-free (LRRFS) survival and local recurrence was evaluated. An electronic search of Medline via PubMed and Embase (Toxicity AND radiation therapy breast cancer AND preoperative therapy; toxicity AND breast surgery AND preoperative chemotherapy) was conducted for outcomes of harm: major acute and late skin toxicity, lymphedema and cardiac events. Results: Of 333 studies identified, 4 retrospective studies reporting on a total of 1107 patients were included in the meta-analysis. Six and 3 reported data of acute and late skin toxicity, while 2 studies provided information on cardiac events. Pooled results showed no difference in terms of hazard ratio for loco-regional RT versus no loco-regional RT [hazard ratio (HR) = 0.82, 95% confidence interval (CI) 0.63\u20131.68]. Loco-regional RT was associated with an OS benefit in the subgroup analysis: IIIB-C (loco-regional RT 79.3% vs no loco-regional RT 71.2%, p = 0.027) and T3-T4 (loco-regional RT 82.6% vs no loco-regional RT 76.6%, p = 0.025). No difference was shown in terms of 5-year DFS (loco-regional RT 91.2% vs no loco-regional RT 83%, p = 0.441) and LRRFS (loco-regional RT 98.1% vs no loco-regional RT 92.3%, p = 0.148). There was no significant difference between the groups in terms of acute and late skin toxicities, lymphedema and cardiac events. Conclusions: Because of the limitations due to the small number of studies and heterogeneity in the analysis, the present study does not allow to draw any definitive conclusion, highlighting the need for well-controlled trials to determine the effect of loco-regional RT in patients with cN2 having a pathological complete response in the axillary nodes after preoperative chemotherapy
