Neurodevelopmental vulnerability to psychosis: developmentally-based methods enable detection of early life inhibitory control deficits that predict psychotic-like experiences at the transition to adolescence

Abstract Background Inhibitory control develops in early childhood, and atypical development may be a measurable marker of risk for the later development of psychosis. Additionally, inhibitory control may be a target for intervention. Methods Behavioral performance on a developmentally appropriate Go/No-Go task including a frustration manipulation completed by children ages 3–5 years (early childhood; n = 107) was examined in relation to psychotic-like experiences (PLEs; ‘tween’; ages 9–12), internalizing symptoms, and externalizing symptoms self-reported at long-term follow-up (pre-adolescence; ages 8–11). ERP N200 amplitude for a subset of these children (n = 34) with electrophysiological data during the task was examined as an index of inhibitory control. Results Children with lower accuracy on No-Go trials compared to Go trials in early childhood (F(1,101) = 3.976, p = 0.049), evidenced higher PLEs at the transition to adolescence 4–9 years later, reflecting a specific deficit in inhibitory control. No association was observed with internalizing or externalizing symptoms. Decreased accuracy during the frustration manipulation predicted higher internalizing, F(2,202) = 5.618, p = 0.004, and externalizing symptoms, F(2,202) = 4.663, p = 0.010. Smaller N200 amplitudes were observed on No-Go trials for those with higher PLEs, F(1,101) = 6.075, p = 0.020; no relationship was observed for internalizing or externalizing symptoms. Conclusions Long-term follow-up demonstrates for the first time a specific deficit in inhibitory control behaviorally and electrophysiology, for individuals who later report more PLEs. Decreases in task performance under frustration induction indicated risk for internalizing and externalizing symptoms. These findings suggest that pathophysiological mechanisms for psychosis are relevant and discriminable in early childhood, and further, suggest an identifiable and potentially modifiable target for early intervention.
Effects of heat waves on telomere dynamics and parental brooding effort in nestlings of the zebra finch (Taeniopygia castanotis) transitioning from ectothermy to endothermy

Heat waves are predicted to be detrimental for organismal physiology with costs for survival that could be reflected in markers of biological state such as telomeres. Changes in early life telomere dynamics driven by thermal stress are of particular interest during the early post‐natal stages of altricial birds because nestlings quickly shift from being ectothermic to endothermic after hatching. Telomeres of ectothermic and endothermic organisms respond differently to environmental temperature, but few investigations within species that transition from ectothermy to endothermy are available. Also, ambient temperature influences parental brooding behaviour, which will alter the temperature experienced by offspring and thereby, potentially, their telomeres. We exposed zebra finch nestlings to experimental heat waves and compared their telomere dynamics to that of a control group at 5, 12 and 80 days of age that encapsulate the transition from the ectothermic to the endothermic thermoregulatory stage; we also recorded parental brooding, offspring sex, mass, growth rates, brood size and hatch order. Nestling mass showed an inverse relationship with telomere length, and nestlings exposed to heat waves showed lower telomere attrition during their first 12 days of life (ectothermic stage) compared to controls. Additionally, parents of heated broods reduced the time they spent brooding offspring (at 5 days old) compared to controls. Our results indicate that the effect of heat waves on telomere dynamics likely varies depending on age and thermoregulatory stage of the offspring in combination with parental brooding behaviour during growth.
Vector diffusion maps and random matrices with random blocks

Vector diffusion maps (VDM) is a modern data analysis technique that is starting to be applied for the analysis of high dimensional and massive datasets. Motivated by this technique, we study matrices that are akin to the ones appearing in the null case of VDM, i.e the case where there is no structure in the dataset under investigation. Developing this understanding is important in making sense of the output of the VDM algorithm whether there is signal or not. We hence develop a theory explaining the behavior of the spectral distribution of a large class of random matrices, in particular random matrices with random block entries. Numerical work shows that the agreement between our theoretical predictions and numerical simulations is generally very good.

Two‐year results of tapered dupilumab for CRSwNP demonstrates enduring efficacy established in the first 6 months

Dupilumab is an anti‐T2‐inflammatory biological registered for chronic rhinosinusitis (CRS) with nasal polyps (CRSwNP), indicated by integrated CRS‐care pathways when optimal medico‐surgical treatment yields insufficient CRS control. This study aims to evaluate long‐term results with focus on established therapeutic efficacy while tapering dupilumab.
Evolution of Proton and Alpha Particle Velocities through the Solar Cycle

Relative properties of solar wind protons and α particles are often used as indicators of a source region on the solar surface, and analysis of their evolution along the solar wind path tests our understanding of physics of multicomponent magnetized plasma. The paper deals with the comprehensive analysis of the difference between proton and α particle bulk velocities at 1 au with a special emphasis on interplanetary coronal mass ejections (ICMEs). A comparison of about 20 years of Wind observations at 1 au with Helios measurements closer to the Sun (0.3–0.7 au) generally confirms the present knowledge that (1) the differential speed between both species increases with the proton speed; (2) the differential speed is lower than the local Alfvén speed; (3) α particles are faster than protons near the Sun, and this difference decreases with the increasing distance. However, we found a much larger portion of observations with protons faster than α particles in Wind than in Helios data and attributed this effect to a preferential acceleration of the protons in the solar wind. A distinct population characterized by a very small differential velocity and nearly equal proton and α particle temperatures that is frequently observed around the maximum of solar activity was attributed to ICMEs. Since this population does not exhibit any evolution with increasing collisional age, we suggest that, by contrast to the solar wind from other sources, ICMEs are born in an equilibrium state and gradually lose this equilibrium due to interactions with the ambient solar wind.
Two coral fluorescent proteins of distinct colors for sharp visualization of cell-cycle progression

We cloned and characterized two new coral fluorescent proteins: h2-3 and 1-41. h2-3 formed an obligate dimeric complex and exhibited bright green fluorescence. On the other hand, 1-41 formed a highly multimeric complex and exhibited dim red fluorescence. We engineered 1-41 into AzaleaB5, a practically useful red-emitting fluorescent protein for cellular labeling applications. We fused h2-3 and AzaleaB5 to the ubiquitination domains of human Geminin and Cdt1, respectively, to generate a new color variant of Fucci (Fluorescent Ubiquitination-based Cell-Cycle Indicator): Fucci5. We found Fucci5 provided more reliable nuclear labeling for monitoring cell-cycle progression than the 1st and 2nd generations that used mAG/mKO2 and mVenus/mCherry, respectively.
Mean Square Stability of Model Based Networked Control Systems with Multiplicative Noise

This paper presents a necessary and su ﬃ cient condition of mean square stability of a model based networked control systems (MB-NCS) with multiplicative noise, where a linear discrete time plant is controlled by using a model state feedback. The lifting approach is employed, and the original time varying system is recast as an equivalent time invariant system whose mean square stability is investigated. The necessary and su ﬃ cient condition derived here is given as a set of a linear matrix inequality and linear equations, which enjoys an advantage on numerical computation
Tunable Perfect Absorption in Continuous Graphene Sheets on Metasurface Substrates

Experimental realization of perfect absorption of electromagnetic waves in graphene is believed to be a challenging task. The main obstacle is the low mobility in processed graphene, which makes the light-matter interactions in graphene weak. In this work, we demonstrate in theory that it is possible to obtain total absorption even in very poor-quality graphene sheets. We use a simple equivalent circuit to explain and quantify the weak absorption in low-quality graphene and propose a new method to solve this problem. Our method is to place a monolayer graphene directly on high-impedance metasurface substrates. Perfect absorption in the terahertz band is achieved in unpatterned graphene sheets without any intentional doping (chemical or electrostatic). We provide guidelines for designing tunable perfect absorbers using graphene of different quality (different carrier mobility). We show that the absorption frequency and level are tunable in a wide range by modifying the Fermi energy. The proposed configuration is structurally simple, compact, and easy to fabricate. The developed graphene-metasurface theoretical model is not limited to the terahertz band, and can be scaled from microwave to mid-infrared ranges by tailoring the metasurface dimensions.
Vascular determinants of hippocampal viscoelastic properties in healthy adults across the lifespan

Arterial stiffness and cerebrovascular pulsatility are non-traditional risk factors of Alzheimer’s disease. However, there is a gap in understanding the earliest mechanisms that link these vascular determinants to brain aging. Changes to mechanical tissue properties of the hippocampus (HC), a brain structure essential for memory encoding, may reflect the impact of vascular dysfunction on brain aging. We tested the hypothesis that arterial stiffness and cerebrovascular pulsatility are related to HC tissue properties in healthy adults across the lifespan. Twenty-five adults underwent measurements of brachial blood pressure (BP), large elastic artery stiffness, middle cerebral artery pulsatility index (MCAv PI), and magnetic resonance elastography (MRE), a sensitive measure of HC viscoelasticity. Individuals with higher carotid pulse pressure (PP) exhibited lower HC stiffness (β = −0.39, r = −0.41, p = 0.05), independent of age and sex. Collectively, carotid PP and MCAv PI significantly explained a large portion of the total variance in HC stiffness (adjusted R2 = 0.41, p = 0.005) in the absence of associations with HC volumes. These cross-sectional findings suggest that the earliest reductions in HC tissue properties are associated with alterations in vascular function.
Activated Wake Systems in Narcolepsy Type 1

Narcolepsy type 1 (NT1) is assumed to be caused solely by a lack of hypocretin (orexin) neurotransmission. Recently, however, we found an 88% reduction in corticotropin‐releasing hormone (CRH)‐positive neurons in the paraventricular nucleus (PVN). We assessed the remaining CRH neurons in NT1 to determine whether they co‐express vasopressin (AVP) to reflect upregulation. We also systematically assessed other wake‐systems, since current NT1 treatments target histamine, dopamine, and norepinephrine pathways.
Rural and Agricultural Natural Disaster Stress and Recovery: A Comparison

ABSTRACT This study used a novel survey instrument to evaluate the hypothesis that U.S. agricultural producers have significantly different stress and recovery experiences following acute-onset natural disaster compared to their non-agricultural counterparts. Participants were recruited through local organizations and targeted email and social media in communities in Arkansas and Nebraska that had experienced violent tornadoes in 2014 and/or severe flooding in 2019. The survey instrument incorporated the Brief Resilience Scale, the Revised Impact of Event Scale referencing two time points, the Posttraumatic Growth Inventory-Short Form, and original questions. Demographic, exposure, stress, and recovery measures were analyzed in SAS with Chi-square tests, t-tests, Wilcoxon tests, and multiple linear regression modeling to test for differences between agricultural and non-agricultural groups in resilience, event exposure, stress symptoms in the week after the event, stress symptoms in the month before the survey, a calculated recovery ratio, and posttraumatic growth. Analysis sample (N = 159) contained 20.8% agricultural occupation, 71.1% female, and 49.1% over age 55. No significant differences were found between agricultural and non-agricultural participants when comparing resilience, stress, or recovery ratio measures. Unadjusted posttraumatic growth score was significantly lower in the agriculture group (P = .02), and an occupation group by sex interaction was significantly associated with posttraumatic growth score (P = .02) when controlled for number of initial posttraumatic stress symptoms in the adjusted model, with agricultural women showing lower growth. Overall, there was no evidence of significant difference in disaster stress and recovery between agricultural and rural, non-agricultural groups in this study. There was some evidence that women in agriculture may have lower levels of recovery. Data indicated that rural residents continue to experience posttraumatic-type symptoms up to 8 years beyond the acute-onset natural disaster events. Communities should include strategies to support mental and emotional health in their preparedness, response, and recovery plans with intentional inclusion of agricultural populations.
The effect and mechanism of motor control exercise on low back pain: a narrative review

Low back pain (LBP) is a common symptom that can occur in all ages. It is the first common cause of disability globally and is associated with over 60 million disability-adjusted life-years in a single year. Motor control exercise (MCE) has obtained increasing attention in treating LBP. However, the findings from distinct meta-analyses differed and some even reached controversial conclusions. More importantly, how MCE improves LBP-related symptoms remains unclear. The primary aim of this study is to describe the possible improvement mechanisms of MCE on LBP from brain, biochemistry, inflammatory, and neuromuscular aspects. The secondary aim is to further conclude its effectiveness and clinical application. Further understanding of mechanisms and effectiveness could be instructive for future LBP treatments and provide more information for clinicians when making prescriptions. MCE is effective in alleviating pain and disability among patients with acute and chronic LBP. Notably, the evidence for acute LBP is relatively low-quality and limited. MCE might be more effective for patients with specific LBP characteristics, especially those with pre-diagnosis of impaired transversus abdominis recruitment, intermediate pain intensity, and longer MCE training duration. MCE could remap brain representation and reverse negative brain alternation, induce exercise-induced hypoalgesia, mediate anti-inflammatory response, retain normal activation, and improve morphological deficits.
Parental breeding decisions and genetic quality predict social structure of independent offspring

Across the animal kingdom, newly independent juveniles form social associations that influence later fitness, mate choice and gene flow, but little is known about the ontogeny of social environments, particularly in wild populations. Here we test whether associations among young animals form randomly or are influenced by environmental or genetic conditions established by parents. Parents' decisions determine natal birth sites, which could affect who independent young initially encounter; secondly, mate choice determines genetic condition (e.g. inbreeding) of young and the parental care they receive, which can affect sociability. However, genetic and environmental factors are confounded unless related offspring experience different natal environments. Therefore, we used a long‐term genetic pedigree, breeding records and social network data from three cohorts of a songbird with high extra‐pair paternity (hihi, Notiomystis cincta) to disentangle (1) how nest location and relatedness contribute to association structure once juveniles disperse away from birth sites, and (2) if juvenile and/or parental inbreeding predicts individual sociability. We detected positive spatial autocorrelation: hihi that fledged closer by were more likely to associate even after dispersing, irrespective of genetic relatedness. Juvenile inbreeding did not predict sociability, but those raised by more inbred fathers formed more, stronger, associations, which did not depend on whether that male was the genetic parent or not. These results suggest that the natal environment created by parents, rather than focal genetic condition, establishes the foundation for social associations. Overall, we highlight how social inheritance may play an important role in population dynamics and evolutionary potential in wild animals.

Forensic Characterization and Genetic Portrait of the Gannan Tibetan Ethnic Group via 165 AI-SNP Loci.

BACKGROUND The Tibetan group is one of the oldest Sino-Tibetan ethnic groups. The origin, migration as well as the genetic background of Tibetans have become the research hotspots in the field of forensic genetics. The use of ancestry informative markers (AIMs) allows the investigation of the genetic background of the Gannan Tibetan group. METHODS In this study, the 165 ancestry informative single nucleotide polymorphism (AI-SNP) loci included in the Precision ID Ancestry Panel were used to genotype 101 Gannan Tibetans using the Ion S5 XL system. The forensic statistical parameters of 165 AI-SNP in the Gannan Tibetan group were calculated. Population genetic analyses including Nei's genetic distances, phylogenetic analyses, pairwise fixation index, principal component analyses and population ancestry composition analyses were also conducted to evaluate the genetic relationships between the Gannan Tibetan group and other reference populations. RESULTS Forensic parameters of the 165 AI-SNP loci indicated that not all of the SNPs showed high genetic polymorphisms in the Gannan Tibetan group. Population genetic analyses indicated that the Gannan Tibetan group had close genetic affinities with East Asian populations, especially with the groups residing in its neighboring geographical regions. CONCLUSIONS The 165 AI-SNP loci in the Precision ID Ancestry Panel showed high ancestral prediction powers for different continental populations. When trying to predict the ancestral information of East Asian subpopulations using this panel, the prediction results are not particularly accurate. The 165 AI-SNP loci showed varying degrees of genetic polymorphisms in the Gannan Tibetan group, and the combined use of these loci could be an effective tool in the forensic individual identification and parentage testing of this group. The Gannan Tibetan group has close genetic affinities with East Asian populations compared with other reference populations, especially tighter genetic relationships with the groups residing in its neighboring geographical regions.
Estimation and inference for generalized semi-varying coefficient models

ABSTRACT This paper is concerned with the estimation and inference in generalized semi-varying coefficient models. An orthogonal projection local quasi-likelihood estimation is investigated, which can easily be used to estimate the model parametric and nonparametric parts. Then an empirical likelihood logarithmic approach to construct the confidence regions/intervals of the nonparametric parts is developed. Under some mild conditions, the asymptotic properties of the resulting estimators are studied explicitly, respectively. Some simulation studies are carried out to examine the finite sample performance of the proposed methods. Finally, the methodologies are illustrated by a real data set.
Observing quantum control of up-conversion luminescence in Dy3+ ion doped glass from weak to intermediate shaped femtosecond laser fields

Controlling the up-conversion luminescence of rare-earth ions in real-time, in a dynamical and reversible manner, is very important for their application in laser sources, fiber-optic communications, light-emitting diodes, color displays and biological systems. In previous studies, the up-conversion luminescence control mainly focused on the weak femtosecond laser field. Here, we further extend this control behavior from weak to intermediate femtosecond laser fields. In this work, we experimentally and theoretically demonstrate that the up-conversion luminescence in Dy3+ ion doped glass can be artificially controlled by a π phase step modulation, but the up-conversion luminescence control behavior will be affected by the femtosecond laser intensity, and the up-conversion luminescence is suppressed by lower laser intensity while enhanced by higher laser intensity. We establish a new theoretical model (i.e. the fourth-order perturbation theory) to explain the physical control mechanism by considering the two- and four-photon absorption processes, and the theoretical results show that the relative weight of four-photon absorption in the whole excitation process will increase with the increase in laser intensity, and the interference between two- and four-photon absorptions results in up-conversion luminescence control modulation under different laser intensities. These theoretical and experimental works can provide a new method to control and understand up-conversion luminescence in rare-earth ions, and also may open a new opportunity to the related application areas of rare-earth ions.
