Post-synthetic modification of amine-functionalized permanently porous coordination cages.

This manuscript explores the post-synthetic modification (PSM) of amine-functionalized porous coordination cages, specifically focusing on the formation of imine bonds through reactions with aldehydes. Targeting various cage topologies, including zirconium-, magnesium-, and molybdenum-based structures, we demonstrate the tunability of cage solubility and porosity through selective functionalization where the proximity of amine groups on the parent cage impacts the extent of modification. The work highlights the reversible nature of imine formation, offering potential applications in solubility switching and mixed-metal solid synthesis.

Development of the retinoic acid receptor alpha-specific antagonist YCT-529 for male contraception: A brief review.

Genetic studies in mice have demonstrated that retinoic acid receptor alpha (RARα) deficiency leads to male infertility without affecting overall viability, suggesting that pharmacological inhibition of this receptor could be a viable contraceptive strategy. This review describes the use of experimental approaches to develop RARα-selective antagonists for male contraception. Initial studies with BMS-189453, a pan-RAR antagonist, showed significant testicular degeneration and reversible infertility in mice.

A new screener predicts Toddlers' language development from age 2-3: The QUILS:TOD.

Language interventions may yield greater benefits for younger children than their older counterparts, making it critical to evaluate children's language skills as early as possible. Yet, assessing young children's language presents many challenges, such as limited attention spans, low expressive language, and hesitancy to speak with an unfamiliar examiner. To address these challenges, the Quick Interactive Language Screener for Toddlers (QUILS:TOD; for children 24- to 36-months of age) was developed as a quick, tablet-based language screener capable of assessing children's vocabulary, syntax, and word learning skills.

Investigating proteogenomic divergence in patient-derived xenograft models of ovarian cancer.

Within ovarian cancer research, patient-derived xenograft (PDX) models recapitulate histologic features and genomic aberrations found in original tumors. However, conflicting data from published studies have demonstrated significant transcriptional differences between PDXs and original tumors, challenging the fidelity of these models. We employed a quantitative mass spectrometry-based proteomic approach coupled with generation of patient-specific databases using RNA-seq data to investigate the proteogenomic landscape of serially-passaged PDX models established from two patients with distinct subtypes of ovarian cancer.

Analysis of nuclear receptor expression in head and neck cancer.

Objective: Studies of squamous cell carcinoma of the head and neck (HNSCC) have demonstrated the importance of nuclear receptors and their associated coregulators in the development and treatment of HNSCC. We sought to characterize members of the nuclear receptor super family through interrogation of RNA-Seq and microarray data.

Materials And Methods: TCGA RNA-Seq data within the cBioportal platform comparing HNSCC samples (n = 515 patients with RNA-Seq data) to normal tissue (n = 82 patients) was interrogated for significant differences in nuclear receptor expression.

Land Use Change Consistently Reduces α- But Not β- and γ-Diversity of Bees.

Land use change threatens global biodiversity and compromises ecosystem functions, including pollination and food production. Reduced taxonomic α-diversity is often reported under land use change, yet the impacts could be different at larger spatial scales (i.e.

Accountable Care Organizations, Child Opportunity Index, and Complicated Appendicitis in Children.

Introduction: Child Opportunity Index (COI) is associated with complicated appendicitis (CA) in children. Value-based care through an accountable care organization (ACO) may modify this association. We aimed to determine if enrollment in our state's ACO, Partners For Kids (PFK), modified the association between COI and CA.

The Detrimental Effect of Stroke on Motor Adaptation.

Background: While it is evident that stroke impairs motor control, it remains unclear whether stroke impacts motor adaptation-the ability to flexibly modify movements in response to changes in the body and the environment. The mixed results in the literature may be due to differences in participants' brain lesions, sensorimotor tasks, or a combination of both.

Objective: We first sought to better understand the overall impact of stroke on motor adaptation and then to delineate the impact of lesion hemisphere and sensorimotor task on adaptation poststroke.

COVID-19 Misperceptions and Masking Compliance: A Support Marshaling Analysis.

Misperceptions strongly influence the extent to which individuals comply with preventative measures. Social support from others, particularly given widespread mistrust in news media among those holding misperceptions, plays an important role in shaping compliance with preventative measures. The impact of social support, however, is not straightforward and not all support results in greater compliance.

Functional dynamics of G protein-coupled receptors reveal new routes for drug discovery.

G protein-coupled receptors (GPCRs) are the largest human membrane protein family that transduce extracellular signals into cellular responses. They are major pharmacological targets, with approximately 26% of marketed drugs targeting GPCRs, primarily at their orthosteric binding site. Despite their prominence, predicting the pharmacological effects of novel GPCR-targeting drugs remains challenging due to the complex functional dynamics of these receptors.

UNDERSTANDING DRUNKOREXIA BEHAVIORS AMONG COLLEGE STUDENTS USING THE THEORY OF PLANNED BEHAVIOR.

Drunkorexia refers to high-risk behaviors that involve the intersection of disordered eating behaviors and risky alcohol consumption. This study utilized the extended Theory of Planned Behavior (TPB) to identify potential psychosocial factors that contribute to drunkorexia among students (484 undergraduate students) from a midwestern Mid-sized university. This cross-sectional study used online surveys designed to measure various drunkorexia-related behaviors including alcohol consumption, calorie restriction, excessive exercise, and purging utilizing antecedents of the TPB.

Depressive Symptoms and Violence Perpetration: Examining the Moderating Influence of Reward Sensitivity and Emotional Reactivity in Community Adults at Elevated Risk for Violent Behavior.

There is growing interest in understanding whether, and under what circumstances, depression confers risk for violence perpetration. To address these questions, we examined whether major depressive disorder (MDD) symptoms correlated with violence perpetration beyond co-occurring externalizing psychopathology, and whether individual differences in reward and emotional reactivity modified depression-violence associations. In a sample of 480 community adults ( =32.

Temperature, violent crime, climate change, and vulnerability factors in 44 United States cities.

Biological and psychological theories suggest complex impacts of heat on aggression and violence. Most previous studies considered temporal intervals of months to years and assumed linear associations. Evidence is needed on daily impacts of temperature on crime, applying non-linear models across different locations.

A Novel, Site-Specific N-Linked Glycosylation Model Provides Mechanistic Insights Into the Process-Condition Dependent Distinct Fab and Fc Glycosylation of an IgG1 Monoclonal Antibody Produced by CHO VRC01 Cells.

The CHO VRC01 cell line produces an anti-HIV IgG1 monoclonal antibody containing N-linked glycans on both the Fab (variable) and Fc (constant) regions. Site-specific glycan analysis was used to measure the complex effects of cell culture process conditions on Fab and Fc glycosylation. Experimental data revealed major differences in glycan fractions across the two sites.

Infant With Beckwith-Wiedemann Requiring Transplant for Hepatic Mesenchymal Hamartoma.

Background: Liver transplantation for unresectable, benign hepatic lesions is rare. Hepatic mesenchymal hamartomas (HMH) are benign, cystic tumors that arise mostly in pediatric populations and can cause compressive symptoms. HMH is rarely associated with placental mesenchymal dysplasia (PMD) and Beckwith-Wiedemann syndrome (BWS).

Mechanical Deformation Behavior of Polymer Blend Thin Films.

Examining the mechanical properties of polymer thin films is crucial for high-performance applications such as displays, coatings, sensors, and thermal management. It is important to design thin film microstructures that excel in high-demand situations without compromising mechanical integrity. Here, a polymer blend of polystyrene (PS) and polyisoprene (PI) is used as a model to explore microscale deformation behavior under uniaxial mechanical testing.

A brief report on biomarkers of cellular senescence associated with liver frailty and length of stay in liver transplantation.

The proportion of older individuals needing liver transplantation is growing, resulting in an increasingly frail patient population. Frailty constitutes a constellation of cognitive and physical symptoms associated with aging and increases the risk of morbidity and mortality. Senescence is a programmed cell fate in response to stress implicated in causing frailty, age-related diseases, and aging itself.
