| 3 | Shell geometric morphometrics in Biomphalaria glabrata (Mollusca: Planorbidae) uninfected and infected with Schistosoma mansoni显示文摘Freshwater planorbid mollusks belonging to the genus Biomphalaria act as intermediate hosts for Schistosoma mansoni,the etiological agent of human intestinal schistosomiasis,in the Neotropical Region.Identification of Biomphalaria spp.are carried out based on morphological characters,and the Schistosoma infection are determined by the presence of cercariae(verified through microscope preparation and mounting).Recently,the geometric morphometrics has proven to be a useful tool for determining shape differences in disease vectors arthropods.Due to this,we used geometric morphometrics to determine Biomphalaria glabrata shell differences(shape and size) between uninfected and infected specimens.We digitalized 12 anatomical points over the shell left side(from umbilicus to the last whorl) by combining type I and II landmarks and sliding semilandmarks;the coordinates were aligned by generalized Procrustes analysis.Principal component analyses were implemented for examining main variation axes,and discriminant analysis for testing group membership significance.We found significant separation between infected and uninfected shell conformation.All specimens were 100% correctly classified.The main differences occur in the peristome.The Kruskal-Wallis test finds significant differences in shell isometric size among infected and uninfected specimens.These findings correspond to other studies of traditional morphometrics,that infected snails showed the reduction in shell size in contrast to those uninfected specimens. | Cesar Parra Jonathan Liria | 2017 | Zoological Systematics2017，42，1： | 0 |
| 4 | Ayahuasca:Uses,Phytochemical and Biological Activities显示文摘Ayahuasca(caapi,yajé),is a psychoactive brew from the Amazon Basin region of South America traditionally considered a“master plant.”It is prepared as a decoction from Banisteriopsis caapi and Psychotria viridis,which it is thought that it stimulates creative thinking and visual creativity.Native healers of the Orinoco and Amazon basins have used traditionally ayahuasca as a healing tool for multiple purposes,particularly to treat psychological disorders in the patients,with some beneficial effects experimentally and clinically validated.Recently,several syncretic religions,as the“Uniao de Vegetal”(UDV)group in Brazil,have been spread around the world.The use of ayahuasca has been popularized by internet and smart-shops,bringing the psychoactive substance to new highs,emerging new“ayahuasqueros.”Ayahuasca has alkaloids asβ-carbolines and dimethyltryptamines,which inhibit the monoamine oxidase and active the 5-HT_(2A)(5-hydroxytryptamine)receptor,respectively,resulting in hallucinations in the users.Ayahuasca induces a psychedelic change in the anteroposterior coupling of the electrophysiological brain oscillations in humans.Traditional ayahuasca beverage is generating pharmacological,commercial and spiritual interest among the scientific community,government people,and different populations worldwide.The goal of this article is to report about the uses,chemistry and biological activities of ayahuasca. | Edgar Antonio Estrella‑Parra Julio Cesar Almanza‑Pérez Francisco Javier Alarcón‑Aguilar | 2019 | Natural Products and Bioprospecting2019，9，4： | 0 |
