Perinatal tobacco smoke exposure in 12,405 mother-infant pairs: findings from the EISL Phase 3 in South America

Javier Mallol · Dirceu Solé · Viviana Aguirre · Carolina S. Aranda · y 11 más

Objective: To determine the prevalence, risk factors for perinatal tobacco smoking, and the effects on infants’ respiratory health in 12,450 mother-infant pairs from South America. Methods: Cross-sectional population-based study in eleven centres from six countries, using a standardised questionnaire completed by paren...

Reconstruction of complex bone defects in the hand with composite flaps including vascularized bone segments: the 3D reconstruction concept

Aldo Giovanni Beltran Pardo · Armando Isaac Reyes Carrillo · Maria Alexandra Bernal Niño · Tamara Galán Pérez · y 1 más

The concept of three dimensional reconstruction not only aims to replace missing tissues, also seeks to restore histological continuity and vascular integration. This text wants to illustrate this showing some cases of complex bone defects in the hand, which requires structural replacement of lost tissue with integrati...

Cenozoic cooling and exhumation history of Southern Ecuador: The role of plate-boundary reorganizations and inboard tectonic conditions

Sandoval-Espinel, Leidy Carolina · Zattin, Massimiliano · Bermúdez, Mauricio A. · Witt, Cesar · y 2 más

The cooling and exhumation history of orogens along subduction systems provides unique constraints on regional tectonic evolution, reflecting the interplay between crustal deformation and plate convergence dynamics. Southern Ecuador lies within a transitional zone between the northern and central Andes, where contrasti...

Echocardiographic Strain Analysis Compared With Assessment of Fibrosis by Cardiac Magnetic Resonance in the Evaluation of Chagas Cardiomyopathy

Laura Marcela Romero‐Acero · Sridhar Mangalesh · Michele Nanna · Ramon Medina‐Mur · y 16 más

ABSTRACT Aim Chagas cardiomyopathy (CC) is characterized by progressive myocardial fibrosis, contractile dysfunction, and structural remodeling. Strain imaging (SI) holds promise for detecting early myocardial impairment, but its utility in tracking CC progression remains unclear. This study evaluated SI's clinical uti...

Recombinant expression of crotoxin and comparison to native crotoxin as immunogens for anti-crotalid antivenoms

Miguel Angel Mejía Sánchez · Samuel Cardoso Arenas · Ricardo Miranda Blancas · Herlinda Clement · y 5 más

The crotoxin complex is identified as the primary lethal toxin in various species of rattlesnakes. It comprises two subunits: CtxA, a non-toxic protein, and CtxB, a minimally toxic enzymatic phospholipase A2. These components exert neurotoxic effects by disrupting neuromuscular transmission, specifically by inhibiting...

Diversification patterns of Haeterini butterflies (Nymphalidae: Satyrinae)

Frasella De Martino · Nicol Rueda-M · Lucas S Barrientos · Paula Vela · y 3 más

Abstract The understanding of evolutionary relationships among insect lineages has received special attention in recent years, leading to an increasing number of studies aiming to shed light on their diversity, biogeography, and species boundaries. Despite the growing use of integrative taxonomic approaches, the positi...

Spondyloarthritis in Latin America: a difficult-to-diagnose challenge

Igor Rueda Cárdenas · Gustavo José Rodriguez-Salas · Ana María Santos · Pedro Santos-Moreno · y 7 más

Spondyloarthritis (SpA) presents unique diagnostic challenges in Latin America (LATAM) due to genetic, clinical, healthcare, and sociocultural factors. The Assessment of SpondyloArthritis international Society (ASAS) classification criteria—developed mainly in North America and European populations—may not accurately r...

Scanning Tunneling Microscopy in high vectorial magnetic fields

Jaime Rumeu Ozores · Miguel Águeda Velasco · Edwin Herrera · Pablo García Talavera · y 9 más

The Scanning Tunneling Microscope (STM) is a powerful instrument to measure electronic density of states at surfaces down to atomic scale. Many systems of interest require studying variations as a function of the magnetic field, which is most often applied perpendicular to the surface. Conventional STM setups make it c...
