Shallow water fish display low phenotypic plasticity to ocean warming and extre...

Shallow water environments have long been recognized by scientists as sentinels for climate change. By analysing the impacts of ocean warming and marine heatwaves (MHW) in species from these areas, we can estimate their plasticity and hence vulnerability to thermal challenges. Pomatoschistus microps is a benthic intertidal fish species inhabiting coastal lagoons where temperature fluctuations are common. Here, ...

Morphological Predictors of Short-Term Response to Intravitreal Bevacizumab in ...

INTRODUCTION: Our purpose was to identify morphological predictive factors of short-term macular functional and anatomical outcomes after monthly intravitreal bevacizumab for the treatment of macular edema (ME) due to central (CRVO) and branch retinal vein occlusion (BRVO). METhODS: Retrospective study of patients with ME secondary to CRVO or BRVO under monthly treatment with intravitreal injections of bevacizu...

Differential effects of food restriction and warming in the two-spotted goby: I...

Climate change is a growing threat to marine organisms and ecosystems, and it is already modifying ocean properties by, for example, increasing temperature and decreasing pH. Increasing water temperature may also lead to an impairment of primary productivity and an overall depletion of available zooplankton. Understanding how the crossover between warming and zooplankton availability impacts fish populations ha...

Does predation exacerbate the risk of endosymbiont loss in heat stressed hermat...

Ocean warming has been a major driver of coral reef bleaching and mass mortality. Coupled to other biotic pressures, corals' ability for acclimatization and adaptation may become compromised. Here, we tested the combined effects of warming scenarios (26, 30, and 32 degrees C) and predation (wound vs. no wound) in coral health condition (paleness, bleaching, and mortality), cellular stress responses (heat shock ...

Warming in shallow waters: Seasonal response of stress biomarkers in a tide poo...

Tide pools are rapidly warming environments with low thermal inertia, where organisms are exposed to potentially stressful conditions. This way, tide pools will be among the first and hardest hit environments by climate warming. Studies of thermal stress in situ are rare, but important so that current thermal stress in the wild can be confirmed and serve as reference for the future. This study aims to investiga...

Conserved fatty acid profiles and lipid metabolic pathways in a tropical reef f...

Climate warming is causing rapid spatial expansion of ocean warm pools from equatorial latitudes towards the subtropics. Sedentary coral reef inhabitants in affected areas will thus be trapped in high temperature regimes, which may become the "new normal". In this study, we used clownfish Amphiprion ocellaris as model organism to study reef fish mechanisms of thermal adaptation and determine how high temperatur...

Perfil da Transplantação de Córnea do Centro Hospitalar São João entre 2011 e 2018

Objetivo: As técnicas de Queratoplastia Lamelar (KL) permitem a substituição seletiva das camadas de córnea alteradas. A KL associa-se a menos complicações, menor taxa de rejeição e melhores resultados funcionais. O Centro Hospitalar de São João (CHSJ) iniciou a realização de KL em 2009. O objetivo deste trabalho é avaliar a evolução das técnicas cirúrgicas e principais indicações para transplante de Córnea no ...
