ERG potassium channels and T‐type calcium channels contribute to the pacemaker and atrioventricular conduction in zebrafish larvae

Jussep Salgado‐Almario, Yillcer Molina, Manuel Vicente, Antonio Martínez‐Sielva, more

Acta Physiologica > 240 > 2 > n/a - n/a

Aim Bradyarrhythmias result from inhibition of automaticity, prolonged repolarization, or slow conduction in the heart. The ERG channels mediate the repolarizing current I_Kr in the cardiac action potential, whereas T‐type calcium channels (TTCC) are involved in the sinoatrial pacemaker and atrioventricular conduction in mammals. Zebrafish have become a valuable research model for human cardiac electrophysiology...

On a ~210 t Caribbean coastal boulder: The huracanolito seaward of the ruins of the Bucanero resort, Juragua, Oriente, Cuba

Kevin Pedoja, Pedro Dunán‐Avila, Julius Jara‐Muñoz, Christine Authemayou, more

Earth Surface Processes and Landforms > 48 > 15 > 3074 - 3090

Coastal boulder deposits (CBDs), named huracanolitos in Cuba, found along rocky shores, result from storms, tropical cyclones or tsunamis. Despite being important indicators for coastal hazard assessment, determining the mode of emplacement of CBDs (storm/hurricane or tsunami) is not easy. We present, for the first time in English, data about CBDs along the shores of the Cuban Archipelago. More specifically,...

Atypical intrinsic neural timescales in temporal lobe epilepsy

Ke Xie, Jessica Royer, Sara Lariviere, Raul Rodriguez‐Cruces, more

Epilepsia > 64 > 4 > 998 - 1011

Objective Temporal lobe epilepsy (TLE) is the most common pharmacoresistant epilepsy in adults. Here we profiled local neural function in TLE in vivo, building on prior evidence that has identified widespread structural alterations. Using resting‐state functional magnetic resonance imaging (rs‐fMRI), we mapped the whole‐brain intrinsic neural timescales (INT), which reflect temporal hierarchies of...

Silvia Marina González‐Herrera, Nuria E. Rocha‐Guzmán, Luis E. Simental‐Mendía, Raúl Rodríguez‐Herrera, more

Journal of Food Processing and Preservation > 43 > 8 > n/a - n/a

The effect of dehydrated apple‐based snack supplemented with Agave fructans on short‐chain fatty acids (SCFA) production in mice was evaluated. Animals were randomly divided into three groups (n = 8): Control group (CG), oligofructose (OG), and Agave fructans (AG). After 24 days of treatment (stage 1), AG and OG showed elevated levels of acetate (10 µmol/g for both treatments), propionate (2.4 µmol/g...
