Design of a light and Ca switchable organic-peptide hybrid.

The design of organic-peptide hybrids has the potential to combine our vast knowledge of protein design with small molecule engineering to create hybrid structures with complex functions. Here, we describe the computational design of a photoswitchable Ca-binding organic-peptide hybrid. The designed molecule, designated Ca-binding switch (CaBS), combines an EF-hand motif from classical Ca-binding proteins such as calmodulin with a photoswitchable group that can be reversibly isomerized between a spiropyran (SP) and merocyanine (MC) state in response to different wavelengths of light.

Impaired spatial coding of the hippocampus in a dentate gyrus hypoplasia mouse model.

The hippocampal dentate gyrus (DG) is thought to orthogonalize inputs from the entorhinal cortex (pattern separation) and relay this information to the CA3 region. In turn, attractor dynamics in CA3 perform a pattern completion or error correction operation before sending its output to CA1. In a mouse model of congenital hypoplasia of the DG, a deficiency in the (Wls) gene, specifically in cells expressing , which targets neuronal progenitors, led to an almost total absence of dentate granule cells and modestly impaired performance in spatial tasks.

Revised Process for ACNS Guidelines Development.

The development of clinical practice guidelines is an evolving field. In response to the need for consistent, evidence-based medical practice, the American Clinical Neurophysiology Society identified the need to update the Society's guideline development process. The American Clinical Neurophysiology Society Guidelines Committee created an action plan with the goal of improving transparency and rigor for future guidelines and bringing existing guidelines to current standards.

Functional characterization of novel anti-DEFA5 monoclonal antibody clones 1A8 and 4F5 in inflammatory bowel disease colitis tissues.

Background: The aberrant expression of α defensin 5 (DEFA5) protein in colonic inflammatory bowel diseases (IBDs) underlies the distinct pathogenesis of Crohn's colitis (CC). It can serve as a biomarker for differentiating CC from Ulcerative colitis (UC), particularly in Indeterminate colitis (IC) cases into UC and CC. We evaluated the specificity of commercially available anti-DEFA5 antibodies, emphasizing the need to further validate their appropriateness for a given application and highlighting the necessity for novel antibodies.

Dual DNA replication modes: varying fork speeds and initiation rates within the spatial replication program in Xenopus.

Large vertebrate genomes duplicate by activating tens of thousands of DNA replication origins, irregularly spaced along the genome. The spatial and temporal regulation of the replication process is not yet fully understood. To investigate the DNA replication dynamics, we developed a methodology called RepliCorr, which uses the spatial correlation between replication patterns observed on stretched single-molecule DNA obtained by either DNA combing or high-throughput optical mapping.

Clinical Utility of Zuranolone for Postpartum Depression: A Narrative Review.

Peripartum depression (PPD) affects approximately one in every eight birthing individuals. Despite a high prevalence, PPD is underdiagnosed and undertreated. Several PPD treatment options exist including psychotherapies, conventional serotonergic-based antidepressants and alternative and integrative medicine approaches.

A spiking neural network for active efficient coding.

Biological vision systems simultaneously learn to efficiently encode their visual inputs and to control the movements of their eyes based on the visual input they sample. This autonomous joint learning of visual representations and actions has previously been modeled in the Active Efficient Coding (AEC) framework and implemented using traditional frame-based cameras. However, modern event-based cameras are inspired by the retina and offer advantages in terms of acquisition rate, dynamic range, and power consumption.

Bibliometric insights into astrocytic roles in depression and treatment.

Objective: Depression is a mental disorder that significantly impairs both physical and mental health. Recent studies have shown that reactive astrogliosis have gained significant attention for their involvement in the pathophysiology of depression. However, there is no bibliometric analysis in this research field.

Salt Based or BaLanced SolUtion-Trends Existing in Indian Intensive Care Units: A Multicenter Prospective Observational Cohort Study (SOLUTE Study).

Combination of reverse shock index and simplified motor score as a strong discriminator of trauma outcomes.

Background: The reverse shock index multiplied by simplified motor score (rSI-sMS) is a novel and rapid measure for assessing injury severity in patients with trauma in prehospital settings; however, its discriminant ability requires further validation.

Methods: A retrospective cohort study was conducted from trauma database of Taipei Tzu Chi Hospital to compare the accuracy of the rSI-sMS with that of the shock index, modified shock index, reverse shock index multiplied by the Glasgow Coma Scale (rSI-GCS), and the reverse shock index multiplied by GCS motor subscale (rSI-GCSM) for discriminating in-hospital mortality, intensive care unit (ICU) admissions, prolonged ICU stays ≥14 days, and prolonged hospital stays ≥30 days in patients with trauma.

Results: A total of 11,760 patients from the trauma database were included.

Prevalence of Moral Injury in Nationally Representative Samples of Combat Veterans, Healthcare Workers, and First Responders.

Background: Moral injury affects a variety of populations who make ethically complex decisions involving their own and others' well-being, including combat veterans, healthcare workers, and first responders. Yet little is known about occupational differences in the prevalence of morally injurious exposures and outcomes in nationally representative samples of such populations.

Objective: To examine prevalence of potentially morally injurious event (PMIE) exposure and clinically meaningful moral injury in three high-risk groups.

Evaluation of the Digital Ventilated Cage® system for circadian phenotyping.

The study of circadian rhythms has been critically dependent upon analysing mouse home cage activity, typically employing wheel running activity under different lighting conditions. Here we assess a novel method, the Digital Ventilated Cage (DVC, Tecniplast SpA, Italy), for circadian phenotyping. Based upon capacitive sensors mounted under black individually ventilated cages with inbuilt LED lighting, each cage becomes an independent light-controlled chamber.

Neural signatures of risk-taking adaptions across health, bipolar disorder, and lithium treatment.

Cognitive and neural mechanisms underlying bipolar disorder (BD) and its treatment are still poorly understood. Here we examined the role of adaptations in risk-taking using a reward-guided decision-making task. We recruited volunteers with high (n = 40) scores on the Mood Disorder Questionnaire, MDQ, suspected of high risk for bipolar disorder and those with low-risk scores (n = 37).

Wanting and liking of Facebook functions and their correlation to problematic use.

A key question about social media use is whether it constitutes an addiction. A possible frame of reference to investigate this question is the Incentive Sensitizations Theory (IST), as it provides a solid empirical background to understand the motivational and hedonic aspects of problematic behaviors. A central assumption of IST that addiction-related cues play a pivotal role in addictive behaviors has remained relatively understudied in the context of social media use.

Comparison of mNGS with conventional methods for diagnosis of cryptococcal meningitis: a retrospective study.

The application of metagenomic next-generation sequencing (mNGS) in the diagnosis of cryptococcal meningitis is relatively under characterized. Here, we retrospectively evaluated data from cryptococcal meningitis patients who were tested using mNGS and/or routine testing, including fungal culture, India ink staining, and cryptococcal antigen (CrAg) testing. The performance of mNGS was then assessed.

The Protocol for the Multi-Ethnic, multi-centre raNdomised controlled trial of a low-energy Diet for improving functional status in heart failure with Preserved ejection fraction (AMEND Preserved).

Introduction: Heart failure with preserved ejection fraction (HFpEF) is characterised by severe exercise intolerance, particularly in those living with obesity. Low-energy meal-replacement plans (MRPs) have shown significant weight loss and potential cardiac remodelling benefits. This pragmatic randomised trial aims to evaluate the efficacy of MRP-directed weight loss on exercise intolerance, symptoms, quality of life and cardiovascular remodelling in a multiethnic cohort with obesity and HFpEF.

Preexisting multimorbidity predicts greater mortality risks related to long-term PM exposure.

Long-term health risk assessments related to ambient fine particulate matter (PM) exposure have been more limited to general population but not towards individuals suffering from multimorbidity. While both multimorbidity and PM are independently linked to elevated mortality risk, their combined effects and interactions remain practically unexplored. A cross-cohort analysis was undertaken on data from 3 prospective cohorts, initially enrolling 869038 adults aged ≥18 years followed up during 2005-2022.

Additive manufacturing in spatial patterning for spinal cord injury treatment.

Combinatorial treatments integrating cells and biomolecules within scaffolds have been investigated to address the multifactorial nature of spinal cord injury (SCI). Current regenerative treatments have been ineffective as they do not consider the spatial positions of various cell types to effectively form functional neural pathways. Emulating the complex heterogeneity of cells in the native spinal cord requires translating the existing biological understanding of spatial patterning in neural development, as well as the influence of biomolecule and mechanical patterning on regional specification and axonal regeneration, to engineer a scaffold for spinal cord regeneration.

Cholesterol affects the binding of proteins to phosphatidic acid without influencing its ionization properties.

Phosphatidic acid (PA) through its unique negatively charged phosphate headgroup binds to various proteins to modulate multiple cellular events. To perform such diverse signaling functions, the ionization and charge of PA's headgroup relies on the properties of vicinal membrane lipids and changes in cellular conditions. Cholesterol has conspicuous effects on lipid properties and membrane dynamics.
