Emergent and robust ferromagnetic-insulating state in highly strained ferroelastic LaCoO thin films.

Transition metal oxides are promising candidates for the next generation of spintronic devices due to their fascinating properties that can be effectively engineered by strain, defects, and microstructure. An excellent example can be found in ferroelastic LaCoO with paramagnetism in bulk. In contrast, unexpected ferromagnetism is observed in tensile-strained LaCoO films, however, its origin remains controversial.

Machine Learning-Enabled Superior Energy Storage in Ferroelectric Films with a Slush-Like Polar State.

Heterogeneities in structure and polarization have been employed to enhance the energy storage properties of ferroelectric films. The presence of nonpolar phases, however, weakens the net polarization. Here, we achieve a slush-like polar state with fine domains of different ferroelectric polar phases by narrowing the large combinatorial space of likely candidates using machine learning methods.

Hypertensive disorders of pregnancy and subsequent risk of Alzheimer's disease and other dementias.

Introduction: Women with hypertensive disorders of pregnancy (HDP) have an increased risk of cardiovascular disease. Whether HDP is also associated with later-life dementia has not been fully explored.

Methods: Using the Utah Population Database, we performed an 80-year retrospective cohort study of 59,668 parous women.

Discovery of Novel Digital Biomarkers for Type 2 Diabetic Nephropathy Classification via Integration of Urinary Proteomics and Pathology.

Background: The heterogeneous phenotype of diabetic nephropathy (DN) from type 2 diabetes complicates appropriate treatment approaches and outcome prediction. Kidney histology helps diagnose DN and predict its outcomes, and an artificial intelligence (AI)-based approach will maximize clinical utility of histopathological evaluation. Herein, we addressed whether AI-based integration of urine proteomics and image features improves DN classification and its outcome prediction, altogether augmenting and advancing pathology practice.

Elephants as an animal model for self-domestication.

Humans are unique in their sophisticated culture and societal structures, their complex languages, and their extensive tool use. According to the human self-domestication hypothesis, this unique set of traits may be the result of an evolutionary process of self-induced domestication, in which humans evolved to be less aggressive and more cooperative. However, the only other species that has been argued to be self-domesticated besides humans so far is bonobos, resulting in a narrow scope for investigating this theory limited to the primate order.

Silent findings: Examination of asymptomatic demyelination in a pediatric US cohort.

Background And Objectives: Limited data is available on children with evidence of silent central nervous system demyelination on MRI. We sought to characterize the population in a US cohort and identify predictors of clinical and radiologic outcomes.

Methods: We identified 56 patients such patients who presented with incidental MRI findings suspect for demyelination, enrolled through our US Network of Pediatric Multiple Sclerosis Centers, and conducted a retrospective review of 38 patients with MR images, and examined risk factors for development of first clinical event or new MRI activity.

Methods: The primary predictor variable was sport played.

Modulation of the mitochondrial Ca uniporter complex subunit expression by different shear stress patterns in vascular endothelial cells.

Mitochondrial calcium ( Ca ) uptake occurs via the Mitochondrial Ca Uniporter (MCU) complex and plays a critical role in mitochondrial dynamics, mitophagy, and apoptosis. MCU complex activity is in part modulated by the expression of its regulatory subunits. Cardiovascular disease models demonstrated altered gene/protein expression of one or multiple subunits in different cells, including vascular endothelial cells (ECs).

The Longitudinal Effects of Second Step Child Protection Unit on Children: Gender as a Moderator.

We investigated the longitudinal effects of the Second Step Child Protection Unit (CPU; Committee for Children) on student outcomes through a randomized controlled trial. Eight schools with a total sample including 2,031 students were assigned randomly to the CPU intervention or the wait-list control condition. We employed a multi-process latent growth model using a structural equation modeling framework which simultaneously analyzed student outcome growth via the effects of the intervention.

Endothelial Cell-Specific Molecule-1 Inhibits Albuminuria in Diabetic Mice.

Background: Diabetic kidney disease (DKD) is the most common cause of kidney failure in the world, and novel predictive biomarkers and molecular mechanisms of disease are needed. Endothelial cell-specific molecule-1 (Esm-1) is a secreted proteoglycan that attenuates inflammation. We previously identified that a glomerular deficiency of Esm-1 associates with more pronounced albuminuria and glomerular inflammation in DKD-susceptible relative to DKD-resistant mice, but its contribution to DKD remains unexplored.

The mitochondrial Ca uniporter channel synergizes with fluid shear stress to induce mitochondrial Ca oscillations.

The mitochondrial calcium (Ca) uniporter (MCU) channel is responsible for mitochondrial Ca influx. Its expression was found to be upregulated in endothelial cells (ECs) under cardiovascular disease conditions. Since the role of MCU in regulating cytosolic Ca homeostasis in ECs exposed to shear stress (SS) is unknown, we studied mitochondrial Ca dynamics (that is known to decode cytosolic Ca signaling) in sheared ECs.

Effects of varenicline and bupropion on laboratory smoking outcomes: Meta-analysis of randomized, placebo-controlled human laboratory studies.

Human laboratory studies are widely used to evaluate behavioural mechanisms of pharmacotherapy effects. Results from human laboratory studies examining smoking cessation pharmacotherapies have not been examined in aggregate. The current meta-analysis aimed to synthesize data from randomized, placebo-controlled human laboratory studies on the effects of non-nicotine pharmacotherapies on outcomes relevant for smoking cessation.

Alcohol and Cannabis Use Milestones in Diverse Urban Adolescents: Associations with Demographics, Parental Rule Setting, Sibling and Peer Deviancy, and Outcome Expectancies.

Alcohol and cannabis use progression milestones in adolescence (such as ages at first use, first intoxication and at onset of regular use) may inform the development of alcohol and cannabis use disorders. Although parent, sibling, and peer behavior and alcohol-related cognitions have been shown to be associated with alcohol milestone attainment, findings have been mixed; further, those factors' associations with cannabis use milestones are unknown. This study examined whether progression through such milestones differed as a function of perceived peer/sibling deviancy, parental rule-setting, and substance use outcome expectancies in a racially diverse adolescent sample.

Cannabis use for sleep aid among high school students: Concurrent and prospective associations with substance use and sleep problems.

Introduction: Adolescents are at risk for both sleep problems and cannabis use. Despite emerging evidence for college students' self-medication with cannabis to help sleep, generalizability to earlier developmental stages remains unknown. This study remedied this literature gap by characterizing high school students' cannabis sleep aid use in terms of psychosocial correlates and prospective associations with substance use and sleep.

Superconducting niobium nitride: a perspective from processing, microstructure, and superconducting property for single photon detectors.

Superconducting niobium nitride (NbN) continues to be investigated decades on, largely in part to its advantageous superconducting properties and wide use in superconducting electronics. Particularly, NbN-based superconducting nanowire single-photon detectors (SNSPDs) have shown exceptional performance and NbN remains as the material of choice in developing future generation quantum devices. In this perspective, we describe the processing-structure-property relationships governing the superconducting properties of NbN films.

Racial/ethnic discrimination, ADH1B*3, and coping-motivated drinking among Black college students.

Background And Objectives: Discrimination due to race and/or ethnicity can be a pervasive stressor for Black college students in the United States beyond general negative life events and has demonstrated associations with adverse health and alcohol outcomes. Genetics may confer individual differences in the risk of drinking to cope with discrimination-related stress. This study tested whether associations of racial/ethnic discrimination with coping drinking motives and alcohol use differ as a function of a well-documented variant in the alcohol dehydrogenase 1B gene (ADH1B*3).

Prevalence of Opioid Use and Intimate Partner Violence among Pregnant Women in South-Central Appalachia, USA.

Recent research indicates that pregnant women in rural communities are at increased risk of experiencing IPV and comorbid illicit opioid use compared to urban-residing pregnant women. Few studies of the interactions among rurality, substance use, and victimization in pregnant women exist. The current study sought to examine the relationship between IPV and opioid use and the interaction effects of rurality in Appalachian pregnant women.

Reducing leakage current and enhancing polarization in multiferroic 3D super-nanocomposites by microstructure engineering.

Multiferroic materials have generated great interest due to their potential as functional device materials. Nanocomposites have been increasingly used to design and generate new functionalities by pairing dissimilar ferroic materials, though the combination often introduces new complexity and challenges unforeseeable in single-phase counterparts. The recently developed approaches to fabricate 3D super-nanocomposites (3D-sNC) open new avenues to control and enhance functional properties.

Strain Engineering: A Pathway for Tunable Functionalities of Perovskite Metal Oxide Films.

Perovskite offers a framework that boasts various functionalities and physical properties of interest such as ferroelectricity, magnetic orderings, multiferroicity, superconductivity, semiconductor, and optoelectronic properties owing to their rich compositional diversity. These properties are also uniquely tied to their crystal distortion which is directly affected by lattice strain. Therefore, many important properties of perovskite can be further tuned through strain engineering which can be accomplished by chemical doping or simply element substitution, interface engineering in epitaxial thin films, and special architectures such as nanocomposites.
