Lactobacillus reuteri DSM 17938 protects agains gastric damage induced by ethan...
Oliveira, Ana P.; Souza, Luan K. M.; Araújo, Thiago S. L.; Araújo, Simone de; Nogueira, Kerolayne M.; Sousa, Francisca Beatriz M.; Silva, Renan O.This study aimed to evaluate the effect of Lactobacillus reuteri DSM 17938 (DSM) on ethanol-induced gastric injury, and if its possible mechanism of action is related to inhibiting the transient receptor potential vanilloid type 1 (TRPV1). We evaluated the effect of supplementing 108 CFU g body wt1 day1 of DSM on ethanol-induced gastric injury. DSM significantly reduced the ulcer area (1.940 1.121 mm2) with 3 d...
Effects of high pCO2 on early life development of pelagic spawning marine fish
Faria, Ana Margarida; Filipe, Soraia; Lopes, Ana F.; Oliveira, Ana P.; Gonçalves, Emanuel João; Ribeiro, LauraThe present study investigated the effect of elevated pCO2 on the development of early stages of the pelagic spawning marine fish Solea senegalensis, Diplodus sargus and Argyrosomus regius. Eggs and larvae were reared under control (pH 8.0, ,570 matm) and two elevated pCO2 conditions (pH 7.8, ,1100 matm; pH 7.6, ,1900 matm) until mouth opening (3 days post-hatching). Egg size did not change with exposure to ele...
Painted Goby Larvae under high-CO2 fail to recognize reef sounds
Castro, Joana M.; Amorim, Maria Clara Pessoa; Oliveira, Ana P.; Gonçalves, Emanuel João; Munday, Philip L.; Simpson, Stephen D.; Faria, Ana MargaridaAtmospheric CO2 levels have been increasing at an unprecedented rate due to anthropogenic activity. Consequently, ocean pCO2 is increasing and pH decreasing, affecting marine life, including fish. For many coastal marine fishes, selection of the adult habitat occurs at the end of the pelagic larval phase. Fish larvae use a range of sensory cues, including sound, for locating settlement habitat. This study teste...

Oliveira, Ana P.; Guimarães, Amanda L.; Pacheco, Alessandra G. M.; Araújo, Camila S.; Oliveira Júnior, Raimundo G.; Lavor, Érica M.; Silva, Mariana G.PHYTOCHEMICAL STUDY ON ANTIMICROBIAL AND CYTOTOXIC ACTIVITY OF SPECIMENS OF Leonotis nepetifolia L. R. (Br). Specimens of Leonotis nepetiflolia were obtained from cultivated and wild environments to verify their influences in chemical composition. Phytochemical analyses were conducted for the ethyl acetate phase obtained by partitioning the crude ethanol extract from the cultivated leaves of L. nepetifolia. In ...
Effects of ocean acidification on the swimming ability, development and biochem...
Silva, Cátia Sofia Esteves da; Novais, Sara C.; Lemos, Marco F. L.; Mendes, Susana; Oliveira, Ana P.; Gonçalves, Emanuel João; Faria, Ana MargaridaOcean acidification, recognized as a major threat to marine ecosystems, has developed into one of the fastest growing fields of research in marine sciences. Several studies on fish larval stages point to abnormal behaviours, malformations and increased mortality rates as a result of exposure to increased levels of CO2. However, other studies fail to recognize any consequence, suggesting species-specific sensiti...
