Myogenesis is essential for skeletal muscle formation, growth, and regeneration and can be altered in Duchenne muscular dystrophy (DMD), an X-linked disorder due to the absence of the cytoskeletal protein dystrophin. Ion channels play a pivotal role in muscle differentiation and interact with the dystrophin complex. To investigate ion channel involvement in myogenesis in dystrophic settings, we performed electrophysiological characterization of two immortalized mouse cell lines, wild-type (WT) H2K-2B4 and the dystrophic (DYS) H2K-SF1, and measured gene expression of differentiation markers and ion channels...

There is much public anxiety about how today's students use chatbots to complete assignments. But AI's integration within schools will more deeply impact the next generation of college graduates. The market value of future college degrees is far from certain.

While humans sometimes do show the capability of correcting their own erroneous guesses with self-critiquing, there seems to be no basis for that assumption in the case of LLMs.

Social bonds influence physiology and behavior, which can shape how individuals respond to physical and affective challenges. Coppery titi monkey (Plecturocebus cupreus) offspring form selective bonds with their fathers, making them ideal for investigating how father-daughter bonds influence juveniles' responses to oxytocin (OT) and arginine-vasopressin (AVP) manipulations. We quantified the expression of father-daughter bond-related behaviors in females (n = 10) and gave acute intranasal treatments of saline, low/medium/high OT, low/high AVP, or an OT receptor antagonist (OTA) to subjects prior to a parent preference test...

This review consolidates current knowledge on mammalian parental care, focusing on its neural mechanisms, evolutionary origins, and derivatives. Neurobiological studies have identified specific neurons in the medial preoptic area as crucial for parental care. Unexpectedly, these neurons are characterized by the expression of molecules signaling satiety, such as calcitonin receptor and BRS3, and overlap with neurons involved in the reproductive behaviors of males but not females. A synthesis of comparative ecology and paleontology suggests an evolutionary scenario for mammalian parental care, possibly stemming from male-biased guarding of offspring in basal vertebrates...

Can lifelong bilingualism be robustly decoded from intrinsic brain connectivity? Can we determine, using a spectrally resolved approach, the oscillatory networks that better predict dual-language experience? We recorded resting-state magnetoencephalographic activity in highly proficient Spanish-Basque bilinguals and Spanish monolinguals, calculated functional connectivity at canonical frequency bands, and derived topological network properties using graph analysis. These features were fed into a machine learning classifier to establish how robustly they discriminated between the groups...

Human musicality (the capacity to make and appreciate music) is difficult to explain in evolutionary terms, though many theories attempt to do so. This paper focuses on musicality's potential adaptive precursors, particularly as related to rhythm. It suggests that pace setting for walking and running long distances over extended time periods (endurance locomotion, EL) is a good candidate for an adaptive building block of rhythmic musicality. The argument is as follows: (1) over time, our hominin lineage developed a host of adaptations for efficient EL; (2) the ability to set and maintain a regular pace was a crucial adaptation in the service of EL, providing proximate rewards for successful execution; (3) maintaining a pace in EL occasioned hearing, feeling, and attending to regular rhythmic patterns; (4) these rhythmic patterns, as well as proximate rewards for maintaining them, became disassociated from locomotion and entrained in new proto-musical contexts...

This review aims to summarize pharmacological interventions that may affect adiposity and metabolic equilibrium in individuals with obesity. Pharmacological therapy is frequently used to treat medical conditions that are both directly related to obesity (such as hypertension and type 2 diabetes) and indirectly related to obesity (such as asthma, insomnia, and type 1 diabetes). This pharmacological therapy may result in weight gain and alterations in the metabolic profile. Many medication classes are implicated in the pharmacologic causes of weight gain, including antipsychotics, glucocorticoids, beta-adrenergic blockers, tricyclic antidepressants, antihistamines, insulin, neuropathic agents, sleep agents, and steroids...

Organismal solutions to natural challenges can spark creative engineering applications. However, most engineers are not experts in organismal biology, creating a potential barrier to maximally effective bioinspired design. In this review, we aim to reduce that barrier with respect to a group of organisms that hold particular promise for a variety of applications: snakes. Representing >10% of tetrapod vertebrates, snakes inhabit nearly every imaginable terrestrial environment, moving with ease under many conditions that would thwart other animals...

This review summarizes the implementation characteristics of parenting interventions to promote early child development (ECD) outcomes from birth to 3 years. We included 134 articles representing 123 parenting trials (PROSPERO record CRD42022285998). Studies were conducted across high-income (62%) and low-and-middle-income (38%) countries. The most frequently used interventions were Reach Up and Learn, Nurse Family Partnership, and Head Start. Half of the interventions were delivered as home visits. The other half used mixed settings and modalities (27%), clinic visits (12%), and community-based group sessions (11%)...

The pathophysiology of oropharyngeal dysphagia (OD) across patient phenotypes may differ. The aim of this study was to compare the biomechanics and neurophysiology of swallowing between healthy volunteers (HVs) and patients with dysphagia as a consequence of aging (OOD), post-stroke (PSOD), Parkinson's disease (POD), or dementia (DOD). A retrospective study including 35 HVs and 109 OOD, 195 PSOD, 78 POD, and 143 DOD patients was performed. Videofluoroscopic data of signs of impaired efficacy and safety, penetration-aspiration scale (PAS) score, and the biomechanics of laryngeal vestibule closure (LVC) and opening (LVO) and of upper esophageal sphincter opening (UESO) were collected...

This article provides an overview of science, technology, engineering, mathematics, and medical sciences (STEMM) talent development from first exposure to a STEMM domain to achieving eminence and innovation. To this end, a resource-oriented model of STEMM talent development is proposed as a framework. It includes a three-stage phase model based on Bloom (1985), with the main focus on interest development in the first stage, skill acquisition toward expertise and excellence in the second stage, and style formation toward eminence and innovation in the final stage...

Our aim was to find the best evidence on the prevalence of idiopathic scoliosis (IS) in subjects with eye diseases (EDs) and to determine the most common visual alterations that are present. Following the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), a bibliographic search up to June 2023 in the PubMed, PsycINFO, SCOPUS, and CINAHL Complete databases was performed. Observational studies were selected and the results were analyzed with prevalence odds ratio (OR)...

Memory control (MC) and emotion regulation (ER) are critical cognitive functions for adapting to life's challenges, drawing significant research attention. Accumulating evidence suggests these processes are interrelated, yet a comprehensive discussion of their interplay remains lacking. We introduce an integrative framework exploring the mutual influence between MC and ER, composed of two interrelated branches: first, MC aids in ER through the retrieval of positive memories, intentional forgetting of undesirable content, and the adaptive updating of memory stores...

Perceptual pleasure and its concomitant hedonic value play an essential role in everyday life, motivating behavior and thus influencing how individuals choose to spend their time and resources. However, how pleasure arises from perception of sensory information remains relatively poorly understood. In particular, research has neglected the question of how perceptual representations mediate the relationships between stimulus properties and liking (e.g., stimulus symmetry can only affect liking if it is perceived)...

Dance has entered mainstream empirical research: dance as an experimental stimulus, and dancers as movement experts. Informed by several sources, including primary sources (original, historical documents, and oral reports, such as interviews with practitioners and academic scholars of Iranian dance genres) and secondary sources (research literature), we describe what we label "Iranian classical dance" within this paper as an important resource for empirical research, not only in humanities scholarship but also, and importantly, for empirical aesthetics, emotion psychology, cross-cultural psychology, and affective neuroscience...

The relationship between integration and awareness is central to contemporary theories and research on consciousness. Here, we investigated whether and how information integration over time, by incorporating the underlying regularities, contributes to our awareness of the dynamic world. Using binocular rivalry, we demonstrated that structured visual streams, constituted by shape, motion, or idiom sequences containing perceptual- or semantic-level regularities, predominated over their nonstructured but otherwise matched counterparts in the competition for visual awareness...

It has been more than a century since Pío del Río-Hortega first characterized microglia in histological stains of brain tissue. Since then, significant advances have been made in understanding the role of these resident central nervous system (CNS) macrophages. In particular, it is now known that microglia can sense neural activity and modulate neuronal circuits accordingly. We review the mechanisms by which microglia detect changes in neural activity to then modulate synapse numbers in the developing and mature CNS...

The task for liberals in our time is to imagine a form of liberalism that is altogether original. If they don't, it does not seem likely that they will see their creed survive-and anyway, survival is not good enough.

Health-related quality of life (HRQOL) is a patient-reported outcome that assesses the impact of a disease or illness on different domains of a patient's life. Different general and disease-specific measures can be used to evaluate HRQOL. This article aimed to summarize the evidence for HRQOL among patients with transfusion-dependent (TDT) and non-transfusion-dependent thalassemia (NTDT). We included HRQOL data related to standard therapy with blood transfusions, iron chelation, and/or luspatercept in TDT and NTDT, as well as curative therapies for TDT, including hematopoietic stem cell transplant (HSCT) and gene therapy...
