Adventices : effets directs et indirects du réchauffement
2021
Contexte - Les conditions météorologiques extrêmes (gels, précipitations extrêmes, sécheresses automnale ou printanière) ont tendance à se multiplier, perturbant les pratiques agricoles,entraînant des pertes de rendement ou l’abandon de la culture. Les effets de la hausse des températures ou de l’allongement de l’ensoleillement sont plus marqués sur les dates de récoltepar exemple.Mais peut-on prévoir l’impact de ces changements climatiques sur les espèces adventices ?¾ effets diReCts - Les interactions entre caractéristiques climatiques, pratiques culturales et traits biologiques dechaque espèce rendent les prévisions difficiles. La hausse des températures peut avoir des effets directs sur…
Flore du blé d’hiver, les facteurs qui influencent sa composition et sa diversité
2014
EA SPE EcolDur EJ2 CT3; National audience; Contexte - Cet article fait suite à une description, dans Phytoma n° 678, de l'évolution de la flore adventice du blé d hiver en France depuis quarante ans, basée sur le travail de Barralis & al. dans les années 1970 et celui du réseau Biovigilance Flore de 2002 à 2010. Il cherche à expliquer ces évolutions. Évolution de la flore - Ce travail a permis de confirmer et évaluer l'influence, sur la flore globale et sa diversité, de la zone géographique, des facteurs pédo-climatiques, du type d'agriculture et des pratiques culturales : notamment IFT herbicide (mesure de l'IC, indice de contrôle) et travail du sol. Analyse par espèce - Une analyse statis…
Microbiome and Probiotics in Acne Vulgaris—A Narrative Review
2022
Acne vulgaris is a chronic disease characterised by the appearance of eruptions such as whiteheads, blackheads, pustules, papules, and cysts. Among factors that cause acne vulgaris are the abnormal keratinisation of the sebaceous canal, bacterial colonisation (Cutibacterium acnes), increased sebum production, genotypic factors, and hormonal disorders. Treatment is often long and tedious, and can lead to a reduction in quality of life and social isolation. The intestinal microbiota is greatly important in the formation of acne lesions. It is also responsible for the proper immunity of the organism. Acne is a disease that can be related to the condition of the digestive tract and its microbio…
Effetto della posizione degli ovoli sulla produttività del carciofo spinoso di sicilia
2010
In Sicily, the Spinoso di Sicilia artichoke is appreciated at regional level for its organoleptic characteristics, but in recent years, its cultivation area has been subject to a progressive reduction because of its susceptibility at the atrophy of head, low earliness, low productivity, and lack of uniformity of the productions. These problems are due to genetic variability, diseases and disforme propagation material (ovoli). This study was conducted to evaluate the influence of the ovoli position (apical, median and basal) in the rhizome of mother plants on morpho-phisiological and productive aspects of the artichokes. The results showed that basal ovoli gave faster growth, better plant co…
Florence Nightingale as a Victorian career woman
2016
The chapter focuses on the role of Florence Nightingale (1820-1910) in turning nursing into a trained profession and a viable and respectable career option for Victorian women seeking employment outside of the home. Nightingale's accomplishments and her thoughts on women's lot in life as expressed in her essay "Cassandra", are presented against the backdrop of the ideology of separate spheres which circumscribes women within the domestic domain. The chapter discusses Nightingale's work in British military field hospitals during the Crimean War, her successful efforts to reform the ways in which such hospitals were run, and the establishment of the Nightingale School and Home for Nurses and …

Enterobacter cloacae administration induces hepatic damage and subcutaneous fat accumulation in high-fat diet fed mice.
2018
Accumulating evidence indicates that gut microbiota plays a significant role in obesity, insulin resistance and associated liver disorders. Family Enterobacteriaceae and especially Enterobacter cloacae strain B29 have been previously linked to obesity and hepatic damage. The underlying mechanisms, however, remain unclear. Therefore, we comprehensively examined the effects of E. cloacae subsp. cloacae (ATCC® 13047™) administration on host metabolism of mice fed with high-fat diet (HFD). C57BL/6N mice were randomly divided into HFD control, chow control, and E. cloacae treatment groups. The E. cloacae treatment group received live bacterial cells in PBS intragastrically twice a week, every ot…
Ipotesi progettuale per il recupero ambientale di una ex discarica sita in c. da Palma, agro di Licata
2006
Il recupero ambientale delle discariche dismesse rappresenta un problema ambientale per la notevole complessità degli aspetti e per le rilevanti competenze richieste. E’ necessario, pertanto, negli interventi di rinaturalizzazione predisporre piani di risanamento mirati e sviluppati sulla base di accurate indagini. Per rinaturalizzazione o rinaturazione si intende quella serie di operazioni di recupero ambientale che, con interventi di bio-ingeneria e con la mitigazione degli impatti, favoriscono il reinstaurarsi di relazioni ecologiche in un’area fortemente degradata come quella in studio. Si tratta di ricreare un ambiente “ospitale” per la flora e per la fauna autoctona, favorendo l’integ…
Conservation status of the endemic vascular flora of Sicily
2022
The results of a comparative study of the quantitative data of the IUCN risk categories attributed to the endemic taxa of the Sicilian vascular flora are reported. 430 Sicilian strictly endemic taxa has been evaluated by comparing the data of the risk categories attributed by published sources. 400 taxa have received at least one assessment of their conservation status, 30 taxa have not yet been considered. 278 received an assessment of their conservation status in accordance with the IUCN criteria, while the remaining 152 have not yet been evaluated according to these criteria.
