Coevolution of rostrum and brain in pig species

Domestic pigs have a prominent cortical gyrus (the rostrum gyrus) isomorphic to the contralateral hemirostrum. It is unclear, however, if the size and shape of the rostrum gyrus are of evolutionary/functional relevance. Here, we address this question by assessing the relationship of rostrum and rostrum gyrus across eight pig species. To this end, we quantified rostrum morphology in fresh and alcohol-preserved pig specimens by surface scans, microfocus computed tomography scans, and photography. We establish that the size and shape of the rostrum gyrus can be precisely inferred from endocasts. We then took advantage of the accessibility of pig skulls and endocasts to assess features of the rostrum gyrus across species. Our investigation led to the following results: (i) The rostra of pig species show basic similarities. (ii) A cortical rostrum gyrus is apparent in all pigs. (iii) The size of the rostrum gyrus differs across species and outgroups of the evolutionary dominant suinae (i.e., peccaries and the babirusa) have a noticeably smaller rostrum gyrus. (iv) Warthogs have a derived rostrum morphology with an extra fold and a very wide rostrum; the warthog rostrum gyrus recapitulates these rostrum features. (v) Domestic pigs have relatively smaller rostrum gyrus than wild boars. We also provide indications for a conserved cytoarchitectonic patterning of the rostrum gyrus. We conclude that the rostrum gyrus is a neural module that was putatively present in the common ancestor of pigs and that this neural module is conserved across pig species. Natural selection maintains the rostrum gyrus’ size and its exact isomorphism to the rostrum.Deutsche Forschungsgemeinschaft http://dx.doi.org/10.13039/501100001659Humboldt‐Universität zu Berlin http://dx.doi.org/10.13039/501100006211Peer Reviewe

Unraveling persistent dyspnea after mild COVID: insights from a case series on hyperventilation provocation tests

Dyspnea is a common yet poorly understood symptom of long COVID, affecting many patients. This brief report examines the role of dysfunctional breathing in persistent dyspnea among patients with mild post-COVID-19 using hyperventilation provocation tests (HVPT). In this case series, six patients with unexplained dyspnea and normal cardiopulmonary function underwent HVPT. Despite normal exercise testing results, all patients exhibited delayed PETCO2 recovery, indicative of a hyperventilation pattern consistent with chronic hyperventilation syndrome, without typical symptomatic manifestations. These findings suggest underlying post-COVID respiratory dysregulation, emphasizing the importance of targeted diagnostic and therapeutic approaches for persistent respiratory symptoms in long COVID patients

REFLEXÕES ACERCA DA AÇÃO DOCENTE PARA O ENSINO DE LÍNGUA PORTUGUESA: TRANSPOSIÇÃO DIDÁTICA EM UMA AULA DE PONTUAÇÃO

In this article, we start from the problem of the teacher not raising reflections on how the process of didactic transposition of a certain content occurs. Our main objective is to discuss the teaching practice in this process, focusing on the content of punctuation. Based on the theoretical assumptions of Verret (1975) and Bakhtin (1992), methodologically, we selected a class taught to a 6th grade elementary school of a public school located in the northwest of Paraná, to analyze, in a specific way, the adjustments made in the planning, besides understanding the characteristics of the didactic transposition. The results show the need to adapt theory to practice, considering the class context, as well as the students' cognitive level. We conclude that scientific knowledge requires to be shaped in an educated knowledge through strategies that contribute to the understanding of content in a more effective and contextualized way.En este artículo, partimos de la problemática de que el docente no suscite reflexiones sobre la manera como ocurre el proceso de transposición didáctica de un determinado contenido. Nuestro objetivo central es discutir la práctica docente en este proceso, centrándose en el contenido de puntuación. Con respaldo en los presupuestos teóricos de Verret (1975) y Bakhtin (1992), metodológicamente, seleccionamos una clase impartida a una clase del 6º año de la Enseñanza Fundamental de una escuela pública situada en el noroeste de Paraná, para analizar, de modo específico, las adaptaciones efectuadas en la planificación, además de comprender las características de la transposición didáctica. Los resultados evidencian la necesidad de hacer adaptaciones de la teoría a la práctica, a considerar el contexto de la clase, así como el nivel cognitivo de los estudiantes. Concluimos que el saber científico requiere ser moldeado en un saber escolarizado por medio de estrategias que contribuyan para la comprensión del contenido de forma más eficaz y contextualizada.Neste artigo, partimos da problemática de o docente não suscitar reflexões quanto à maneira como ocorre o processo de transposição didática de um determinado conteúdo.
