Modulation of in vitro Network Activity by Optogenetic Stimulation of Parvalbumin-positive Interneurons During Estrous Cycle.

Background: Catamenial epilepsy, which is defined as a periodicity of seizure exacerbation occurring during the menstrual cycle, has been reported in up to 70% of epileptic women. These seizures are often non-responsive to medication and our understanding of the relation between menstrual cycle and seizure generation (i.e.

Combinatorial Nanoparticle-Bound ssDNA Oligonucleotide Library Synthesized by Split-and-Pool Synthesis.

Synthetic ssDNA oligonucleotides hold great potential for various applications, including DNA aptamers, DNA digital data storage, DNA origami, and synthetic genomes. In these contexts, precise control over the synthesis of the ssDNA strands is essential for generating combinatorial sequences with user-defined parameters. Desired features for creating synthetic DNA oligonucleotides include easy manipulation of DNA strands, effective detection of unique DNA sequences, and a straightforward mechanism for strand elongation and termination.

Increased attention towards progress information near a goal state.

A growing body of evidence across psychology suggests that (cognitive) effort exertion increases in proximity to a goal state. For instance, previous work has shown that participants respond more quickly, but not less accurately, when they near a goal-as indicated by a filling progress bar. Yet it remains unclear when over the course of a cognitively demanding task do people monitor progress information: Do they continuously monitor their goal progress over the course of a task, or attend more frequently to it as they near their goal? To answer this question, we used eye-tracking to examine trial-by-trial changes in progress monitoring as participants completed blocks of an attentionally demanding oddball task.

Provided and received positive and negative social control, relationship satisfaction, and sedentary behavior in parent-child dyads.

Background: The close relationship processes and health model and the dyadic health influence model posit that relationship beliefs (eg, relationship satisfaction) and influence strategies (eg, provision and receipt of positive and negative social control) mediate health behavior change. However, evidence for such mediation in parent-child dyads is limited.

Purpose: Two complementary mediation hypotheses were tested: (1) social control forms indirect relationships with sedentary behavior (SB), via relationship satisfaction acting as a mediator; and (2) relationship satisfaction forms indirect relationships with SB, with social control operating as a mediator.

A comprehensive experience-based framework of actionable priorities to enhance Canada's health and social care system: discussions with older persons, clinicians, managers, and decision-makers using nominal group technique.

Background: Existing frameworks of older persons' experiences in health and social care systems are usually based on single stakeholder perspectives and focused on limited aspects that are independent from one another. This study aimed to describe such experiences from the perspective of diverse stakeholders and develop a comprehensive experience-based framework for actionable priorities to enhance Canada's health and social care system.

Methods: We adapted a nominal group technique with a qualitative approach.

Advancing scaling science in health and social care: a scoping review and appraisal of scaling frameworks.

Background: Scaling is typically discussed as a way to amplify or expand a health innovation. However, there is limited knowledge about the specific techniques that can enhance access to or improve the quality of innovations, aiming to increase their positive impacts for the public good. We sought to identify, compare, and contrast scaling frameworks to advance the science and practice of scaling.

Non-collapsibility and built-in selection bias of period-specific and conventional hazard ratio in randomized controlled trials.

Background: The hazard ratio of the Cox proportional hazards model is widely used in randomized controlled trials to assess treatment effects. However, two properties of the hazard ratio including the non-collapsibility and built-in selection bias need to be further investigated.

Methods: We conduct simulations to differentiate the non-collapsibility effect and built-in selection bias from the difference between the marginal and the conditional hazard ratio.

Monitoring of nonspatial information within working memory in the common marmoset (Callithrix jacchus).

The mid-dorsolateral prefrontal cortical region (areas 46 and 9/46) is critical for the monitoring of information in working memory both in the macaque monkey brain and the human brain. The presence of this cytoarchitectonic region in the New World marmoset brain was in debate, but recent anatomical evidence demonstrated a limited area 46. This finding raised the question of the extent to which the marmoset brain can support the cognitive control process of monitoring information within working memory.

Quality of Life in Mild Cognitive Impairment and Mild Dementia Associated with Alzheimer's Disease: A Systematic Review.

Mild cognitive impairment (MCI) and Alzheimer's disease (AD) have a profound impact on patients' quality of life (QoL), with progressive declines occurring as the disease advances. This systematic review aims to summarize the published evidence on patient-reported outcomes (PROs) in individuals with MCI due to AD and mild AD dementia. Comprehensive searches were conducted across five major databases to identify studies reporting on utility values, disutilities, and QoL measures in these patient populations.

Beyond the Whole: Reduced Empathy for Masked Emotional Faces Is Not Driven by Disrupted Configural Face Processing.

Sharing of emotional states is reduced for individuals wearing face coverings, but the mechanism behind this reduction remains unknown. Here, we investigated if face occlusion by masks reduces empathy by disrupting configural processing of emotional faces. Participants rated their empathy for happy and neutral faces which were presented in upright or inverted orientation and wore opaque, clear, or no face masks.

When Jack isn't Jacques: Simultaneous opposite language-specific speech perceptual learning in French-English bilinguals.

Humans are remarkably good at understanding spoken language, despite the huge variability of the signal as a function of the talker, the situation, and the environment. This success relies on having access to stable representations based on years of speech input, coupled with the ability to adapt to short-term deviations from these norms, e.g.

A qualitative study exploring the perinatal experiences of social stress among first- and second-generation immigrant parents in Quebec, Canada.

Background: Perinatal psychological distress adversely impacts the well-being and social adjustment of parents and their children. Expectant parents who have migrated may be at higher risk for perinatal psychological distress due to various migration-specific stressors and healthcare service barriers. Limited studies have examined the perceived determinants of perinatal distress in immigrant parents, particularly men.

The child the apple eats: processing of argument structure in Mandarin verb-final sentences.

Mandarin Chinese is typologically unusual among the world's languages in having flexible word order despite a near absence of inflectional morphology. These features of Mandarin challenge conventional linguistic notions such as subject and object and the divide between syntax and semantics. In the present study, we tested monolingual processing of argument structure in Mandarin verb-final sentences, where word order alone is not a reliable cue.

Low concentration dimethyl sulfoxide (DMSO) modulates epileptiform synchronization in the 4-aminopyridine in vitro model.

Dimethyl sulfoxide (DMSO) is commonly used to dissolve water-insoluble drugs due to its dipolar and aprotic properties. It also serves as a vehicle in many pharmacological studies. However, it has been reported that DMSO can induce seizures in human patients, lower seizure threshold in vivo, and modulate ion receptors activities in vitro.

Preclinical assessment for translation to humans: The PATH approach for assessing supporting evidence for early-phase trials and innovative care.

Early-phase trials and innovative care draw support from basic science, preclinical studies, and clinical research. Such evidential diversity presents a challenge for traditional ways of synthesizing evidence. In what follows, we review the limitations of existing approaches for communicating supporting evidence for early-phase trials.

Socioeconomic differences and global trends in youth wellbeing and emotional distress in 165 countries and territories.

Social stratifications in youth wellbeing are a concern for social policy. Using data from the Gallup World Poll (2009-2022), we examined time trends and income differences in youth wellbeing and their associations with area-level income and income inequality. Results showed that a growing proportion of youth have experienced emotional distress in recent years, and this trend disproportionately affected youth at lower incomes.

Neuroimaging and behavioral evidence of sex-specific effects of oxytocin on human sociality.

Although the social role of oxytocin came to light due to sex-specific interactions such as mother-offspring bonding, current understanding of sex differences in the effects of oxytocin on human sociality is limited because of the predominance of all-male samples. With the increasing inclusion of females in intranasal oxytocin research, it is now possible to explore such patterns. Neuroimaging studies reveal relatively consistent sex-differential effects of oxytocin on the activation of brain regions associated with processing social stimuli - particularly the amygdala.
