Efectos del ajo en ratones infectados experimentalmente con Echinostoma caproni
2017
Debido a la inexistencia de vacunas antihelmínticas, el control de las infecciones por helmintos intestinales depende fundamentalmente de las medidas higiénico-sanitarias y de la quimioterapia. Sin embargo, la continua aparición de resistencias a los tratamientos habituales hace necesario desarrollar nuevos fármacos contra estos parásitos. En este trabajo, se han investigado los potenciales efectos antihelmínticos del ajo (Allium sativum), a dosis dietéticas, sobre trematodos intestinales trasmitidos por alimentos, empleando para ello el modelo Echinostoma caproni-roedor. Los efectos potenciales del consumo del ajo en la prevención y/o tratamiento de la infección se analizaron siguiendo dif…

The influence of adult worm age and definitive host on the transmission of Echinostoma caproni: egg hatchability and miracidial infectivity.
2012
AbstractWe analysed the influence of different ages of Echinostoma caproni adult worms reared in different definitive host-species on egg hatchability and miracidial infectivity. Eggs obtained from 2-, 4- and 6-week-old adult worms collected from rats, hamsters and mice, hatched miracidia that were used to infect laboratory-reared specimens of Biomphalaria glabrata. Highest egg hatchability was obtained with eggs derived from hamsters and mice. Egg hatchability did not seem to be affected by the age of E. caproni adult worms. Miracidial infectivity was not affected by the definitive host species. However, miracidial infectivity was affected by the age of adult worms when they developed in t…
Invazīvo augu (Lupinus polyphyllus, Impatiens glandulifera, Echinocystis lobate) bioloģiski aktīvo vielu grupas un to izmantošanas potenciāls bioekon…
2022
Invazīvās augu sugas var veicināt ar ekosistēmu funkcionēšanu saistītas problēmas, radot ekonomiskus zaudējumus, kaitējumu cilvēka veselībai un samazinot rekreācijas resursu kvalitāti. Tās raksturo strauja un agresīva izplatīšanās, nomācot endēmiskās sugas. Pilnīgai invazīvo augu biomasas izmantošanai ir nepieciešams atrast ilgtspējīgus, bioekonomikā balstītus pārstrādes risinājumus, kas ļautu iegūt komponentus vai produktus ar augstu pievienoto vērtību. Darbā tika apskatītas dažādas daudzlapu lupīnas, puķu spriganes un adatainā dzeloņgurķa augu daļas. Augos tika noteikts kopējais polifenolu daudzums, novērtēta antiradikālā aktivitāte (DPPH), un lupīnās atrodamie alkaloīdi (GC-MS). Augstākā…
Safety of micafungin in prospective and retrospective clinical trials
2012
Summary Managing fungal diseases remains a major challenge for clinicians despite the improved armamentarium of antifungal agents. This review identified 19 publications reporting safety data on micafungin. Two of these publications were spin off publications, the remaining 17 (15 prospective, two retrospective) were included in the main assessment. Major adverse events reported which occurred in more than 2% in the study populations were infusion-related, gastro-intestinal and hepatic (LFT parameters elevations). Micafungin demonstrated significantly less renal events compared with liposomal amphotericin B and less hepatic events compared with voriconazole. Compared with fluconazole no sig…
Cytotoxicity and modes of action of four Cameroonian dietary spices ethno-medically used to treat cancers: Echinops giganteus, Xylopia aethiopica, Im…
2013
Abstract Ethnopharmacological relevance. Echinops giganteus , Imperata cylindrica , Piper capense and Xylopia aethiopica are four medicinal spices used in Cameroon to treat cancers. Aim of the study The above plants previously displayed cytotoxicty against leukemia CCRF-CEM and CEM/ADR5000 cell lines as well as human pancreatic MiaPaCa-2 cells. The present study aims at emphasizing the study of the cytotoxicity and the modes of action of the above plants on a panel of ten cancer cell lines including various sensitive and drug-resistant phenotypes. The study has been extended to the isolation of the bioactive constituents from Echinops giganteus . Materials and methods The cytotoxicity of th…
Fossil echinoid (Echinoidea, Echinodermata) diversity of the Early Cretaceous (Hauterivian) in the Paris Basin (France).
2013
11 pages; International audience; This dataset inventories occurrence records of fossil echinoid specimens collected in the Calcaires à Spatangues Formation (CSF) that crops out in the southeast of the Paris Basin (France), and is dated from the Acanthodiscus radiatus chronozone (ca. 132 Ma, early Hauterivian, Early Cretaceous). Fossil richness and abundance of the CSF has attracted the attention of palaeontologists since the middle of the nineteenth century. This dataset compiles occurrence data (referenced by locality names and geographic coordinates with decimal numbers) of fossil echinoids both collated from the literature published over a century and a half, and completed by data from …
Manipulative parasites may not alter intermediate host distribution but still enhance their transmission: field evidence for increased vulnerability …
2013
SUMMARYBehavioural alterations induced by parasites in their intermediate hosts can spatially structure host populations, possibly resulting in enhanced trophic transmission to definitive hosts. However, such alterations may also increase intermediate host vulnerability to non-host predators. Parasite-induced behavioural alterations may thus vary between parasite species and depend on each parasite definitive host species. We studied the influence of infection with 2 acanthocephalan parasites (Echinorhynchus truttae and Polymorphus minutus) on the distribution of the amphipod Gammarus pulex in the field. Predator presence or absence and predator species, whether suitable definitive host or …
Sintesi chimica di nuovi agenti fotochemioterapici eterociclici, con attività antiproliferativa compresa quella di natura neoplastica
2009
La presente invenzione riguarda la sintesi di nuovi analoghi dell’angelicina, pirrolo[3,2-h]chinolinoni, per la cura di patologie a carattere iperproliferativo comprese quelle di natura neoplastica. La cura si basa sull’azione combinata dei pirrolo[3,2-h]chinolinoni e luce UV-A attraverso una nuova tipologia di fotochemioterapia. Questi nuovi derivati hanno dimostrato interessante fototossicità in vitro nei confronti di cellule tumorali umane ma senza indurre un fotodanno al DNA, il quale rappresenta la principale causa degli effetti collaterali della terapia PUVA.
Distribution models and environmental changes : Application to echinoid faunas in the Southern Ocean and ecoregionalization
2018
Current environmental changes, which impact marine environments, cover major scientific and societal issues, especially as these environmental changes are expected to accelerate along the 21st century. Understanding and forecasting the response of marine biodiversity to these changes is a pregnant scientific issue. Biogeographic and macroecological approaches provide a scientific framework for that purpose. They allow describing and understanding species distribution patterns at large spatial scale as well as estimating their potential shift with regards to environmental change. This is particularly true in the Southern Ocean, where the effects of climate change are already occurring and wh…
