Glyphosate-based herbicide has soil-mediated effects on potato glycoalkaloids and oxidative status of a potato pest
2020
Glyphosate is the most used herbicide worldwide, targeting physiological pathways in plants. Recent studies have shown that glyphosate can also cause toxic effects in animals. We investigated the glyphosate-based herbicide (GBH)-induced changes in potato (Solanum tuberosum) plant chemistry and the effects of a GBH on the survival rate and oxidative status of the Colorado potato beetle (Leptinotarsa decemlineata). The beetles were reared on potato plants grown in pots containing soil treated with a GBH (Roundup Gold, 450 g/l) or untreated soil (water control). The 2nd instar larvae were introduced to the potato plants and then collected in 2 phases: as 4th instar larvae and as adults. The ma…
Polyamines and microbiota in bicuspid and tricuspid aortic valve aortopathy
2019
Polyamines are small aliphatic cationic molecules synthesized via a highly regulated pathway and involved in general molecular and cellular phenomena. Both mammalian cells and microorganisms synthesize polyamines, and both sources may contribute to the presence of polyamines in the circulation. The dominant location for microorganisms within the body is the gut. Accordingly, the gut microbiota probably synthesizes most of the polyamines in the circulation in addition to those produced by the mammalian host cells. Polyamines are mandatory for cellular growth and proliferation. Established evidence suggests that the polyamine spermidine prolongs lifespan and improves cardiovascular health in …

The diagnostic significance of cholescintigraphy and ultrasound examination in cholestatic syndromes in infancy
1988
Thirty-three neonates and infants with cholestatic syndromes of various etiologies were evaluated by cholescintigraphy and ultrasound examinations. The results of these two diagnostic procedures were compared with the final diagnosis as confirmed by liver biopsy and/or laparotomy and the clinica follow-up of the infants. Fourteen patients had an obstructive cholangiopathy (11 biliary atresia, 2 choledochal cysts, 1 congenital choledochal stenosis), 13 had neonatal hepatitis, and 6 had cholestasis of another etiology. Typical ultrasonic and/or scintigraphic findings confirmed or excluded the need for surgical exploration in 28 patients. Thus, for must infants with cholestatic syndromes it is…
Michele Lojacono-Pojero’s Centuriae in the herbaria and archives in Geneva
2012
Lojacono, well known as the author of a Flora sicula, offered for sale and distributed various exsiccata. In particular, he prepared 7 Centuriae of Plantae siculae rariores (1879-1884) and 4 Centuriae of Plantae italicae selectae (1885-1888). Swiss botanists (Barbey, Boissier, Burnat) were among his first customers. From their legacy, printed, mostly autographic inventories of all but one of these Centuriae (with only the second Italian Centuria missing) came to the archives of the Conservatoire botanique in Geneva, some in two different versions. These rare documents have been dated with the aid of mail stamps and of correspondence kept in the same archives, and transcripts of all of them …
The Herbarium of Antoine Bras (1803-1883)
2012
Bras, distinguished French amateur botanist and author of a catalogue of the flora of his home province (département de l’Aveyron), built a considerable personal herbarium through 50 years of active collecting (1833-1882). That herbarium, long believed lost, was auctioned in 2008 and acquired by the first author for the Palermo Herbarium (PAL-Gr). Its c. 25,000 specimens are being mounted and databased, with a view of making the digital images and label data available for online consultation. An analysis based on a first sample of 1550 specimens is presented, with explanations of Bras’ labelling and numbering systems and a list of other collectors and correspondents (81 to date) who contrib…
A Comparison of Multi-objective Algorithms for the Automatic Design Space Exploration of a Superscalar System
2013
In today’s computer architectures the design spaces are huge, thus making it very difficult to find optimal configurations. One way to cope with this problem is to use Automatic Design Space Exploration (ADSE) techniques. We developed the Framework for Automatic Design Space Exploration (FADSE) which is focused on microarchitectural optimizations. This framework includes several state-of-the art heuristic algorithms.
Difficulties in Teaching Modelling: A French-Spanish Exploration
2017
An exploratory research study based on an online questionnaire in order to better understand difficulties encountered in teaching of mathematical modelling in France and Spain is presented. This questionnaire takes into account biographical variables, mathematics and modelling conceptions of pre-service teachers, teachers, researchers and education inspectors, from primary to tertiary education. Regarding difficulties, heterogeneous conceptions are revealed, and the analysis constructs four clusters, from positive and confident conceptions to negative and lacking confidence. In some cases, the roles of some biographical variables are indicated such as country, age, gender or school level th…
