A finding at the Natural History Museum of Florence affords the holotype designation of Orchestia stephenseni Cecchini, 1928 (Crustacea: Amphipoda: T…
2017
The beach flea Orchestia stephenseni has been originally described by Cecchini twice (1928, 1929) from the La Spezia type locality (northern Tyrrhenian Sea, Italy), and successively re-described by Karaman (1973) and Iaciofano & Lo Brutto (2016).
Re-description of Orchestia stephenseni Cecchini, 1928: designation of neotype and senior synonym to Orchestia constricta A. Costa, 1853 (Crustacea: …
2016
The beach flea Orchestia stephenseni was originally described by Cecchini (1928), and successively by Karaman (1973). The description of this species will be herein revised by focusing on the variation of the g nathopod 2 in males, as detected during its growth period. An analysis of DNA Barcoding was performed to support the assignment of the taxonomic species to five morphotypes. As the type specimen has not yet been designated, a neotype is assigned. The name of the species is here presented as a valid name as it satisfies the requirements of a Reversal of the Principle of Priority: Orchestia stephenseni takes precedence over the objective synonym Orchestia constricta A. Costa, 1853, in …
A Wickerhamomyces anomalus Killer Strain in the Malaria Vector Anopheles stephensi
2013
The yeast Wickerhamomyces anomalus has been investigated for several years for its wide biotechnological potential, especially for applications in the food industry. Specifically, the antimicrobial activity of this yeast, associated with the production of Killer Toxins (KTs), has attracted a great deal of attention. The strains of W. anomalus able to produce KTs, called "killer" yeasts, have been shown to be highly competitive in the environment. Different W. anomalus strains have been isolated from diverse habitats and recently even from insects. In the malaria mosquito vector Anopheles stephensi these yeasts have been detected in the midgut and gonads. Here we show that the strain of W. a…
Verso una Sintesi Estesa: la riscoperta dell'epigenetica
2020
Fin dagli anni Quaranta del XX secolo, con il paesaggio epigenetico di Conrad Waddington, l’idea che l’ereditarietà degli organismi non dipendesse soltanto dal codice genetico aveva suscitato l’interesse degli studiosi. Nonostante ciò, il neodarwinismo della Sintesi Moderna si poneva come la migliore eredità possibile dell’evoluzionismo di Charles Darwin. Il dibattito riprenderà forza a partire dagli anni Settanta con la teoria della costruzione delle nicchie e, con le evidenze della biologia molecolare, prenderà sempre più piede nelle ricerche scienti che contemporanee aprendo alla possibilità, già avanzata da Stephen Jay Gould, di un’evoluzione che procede per livelli di erenti e in relaz…

Huumeet ja kirjailijoiden luovuus
2017
Pro gradu -tutkielmani käsittelee huumeiden ja kirjailijoiden luovuuden välistä yhteyttä. Kirjailijat ja alkoholi yhdistetään helposti toisiinsa, ja erityisesti siten, että alkoholi on ollut muusa. Alkoholiin mieltyneiden kirjailijoiden lisäksi historia tuntee myös huumeita käyttäneitä kirjailijoita. Miten huumeet vaikuttivat heidän luovuuteensa? Oliko eri huumeilla erilaisia vaikutuksia? Vai oliko huumeista pikemminkin haittaa luovalle työlle? Tarkastelen neljän hyvin erilaisen kirjailijan päihteidenkäyttöhistoriaa ja tuotantoa. Kirjailijat ovat William S. Burroughs, Jack Kerouac, Hunter S. Thompson ja Stephen King. Heistä vain viimeksi mainittu on vielä elossa. Otan myös huomioon kirjaili…
DNA content in nine species of Nematocera with special reference to the sibling species of the Anopheles maculipennis group and the Culex pipiens gro…
1972
DNA values were determined for the nine species: Telmatoscopus meridionalis (family Psychodidae), Dixa obscura (family Dixidae), and Culiseta litorea, Culex pipiens, Aedes caspius, Anopheles labranchiae, Anopheles atroparvus, Anopheles stephensi, and Anopheles freeborni (family Culicidae). The DNA content indicated that the species could be divided into three categories: The Culex group with Culex pipiens, Culiseta litorea and Aedes caspius containing 1.02, 0.92 and 0.99 pg DNA in the haploid set, the Anopheles group including the four Anopheles species A. labranchiae, A. atroparvus, A. stephensi, A. freeborni and Telmatoscopus meridionalis with 0.23, 0.24, 0.24, 0.29 and 0.24 pg DNA and th…

Pharmacological and chemical features ofNepetaL. genus: Its importance as a therapeutic agent
2017
Medicinal plants have always had great value for the human population due to their valuable constituents and potential bioactivities. The objective of this review is to present an updated overview of an important medicinal plant genus Nepeta L., from the family Lamiaceae, revealing its traditional utilization, biological activity, phytoconstituents, and mechanisms of action. For this purpose, a literature survey was carried out by using SciFinder, ScienceDirect, Scopus, PubMed, and Web of Science followed by a revision of the bibliographies of the related articles. We have described and analyzed the role of plants in drug discovery and the importance of Nepeta species. Information on the ut…
