Substituent and Heteroatom Effects on π-π Interactions: Evidence That Parallel-Displaced π-Stacking is Not Driven by Quadrupolar Electrostatics.

Stacking interactions are a recurring motif in supramolecular chemistry and biochemistry, where a persistent theme is a preference for parallel-displaced aromatic rings rather than face-to-face π-stacking. This is typically explained in terms of quadrupole-quadrupole interactions between the arene moieties but that interpretation is inconsistent with accurate calculations, which reveal that the quadrupolar picture is qualitatively wrong. At typical π-stacking distances, quadrupolar electrostatics may differ in sign from an exact calculation based on charge densities of the interacting arenes.

The role of the hippocampus in working memory and word reading: Novel neural correlates of reading among youth living in the context of economic disadvantage.

A left-lateralized cortical reading circuit underlies successful reading and fails to engage in individuals with reading problems. Studies identifying this circuit included youth from economically advantaged backgrounds and focused on cortical, not subcortical, structures. However, among youth with low scores on reading tests who are living in the context of economic disadvantage, this brain network is actively engaged during reading, despite persistent reading problems.

Mental illness and personal recovery: A narrative identity framework.

This article presents a metamorphic model to describe the manifold role of narrative identity, a person's internal life story, across the course of mental illness and personal recovery. First, early adversity and negative co-authoring may contribute to the development of a fragile life story, which itself may combine with life stressors to increase the likelihood of mental illness. Second, mental illness may negatively impact the development of narrative identity, which in turn may exacerbate the devastating effects of mental illness on daily functioning.

Feasibility of measuring magnetic resonance elastography-derived stiffness in human thoracic aorta and aortic dissection phantoms.

Type B aortic dissection (TBAD) represents a serious medical emergency with up to a 50% associated 5-year mortality caused by thoracic aorta, dissection-associated aneurysmal (DAA) degeneration, and rupture. Unfortunately, conventional size-related diagnostic methods cannot distinguish high-risk DAAs that benefit from surgical intervention from stable DAAs. Our goal is to use DAA stiffness measured with magnetic resonance elastography (MRE) as a biomarker to distinguish high-risk DAAs from stable DAAs.

Choroid plexus-targeted viral gene therapy for alpha-mannosidosis, a prototypical neurometabolic lysosomal storage disease.

The choroid plexuses (CP) are highly vascularized structures that project into the ventricles of the vertebrate brain. The polarized epithelia of the CP produce cerebrospinal fluid by transporting water and ions into the ventricles from the blood and normally secrete a large number of proteins. We assessed the feasibility of selective CP transduction with recombinant adeno-associated virus (rAAV) gene therapy vectors for treatment of lysosomal storage disease (LSD), a broad category of neurometabolic illness associated with significant burdens to affected patients and their families.

Effects of adipose allograft matrix on viability of humeral head cartilage and rotator cuff tendon.

Background: Rotator cuff repairs may fail because of compromised blood supply, suture anchor pullout, or poor fixation to bone. To augment the repairs and promote healing of the tears, orthobiologics, such a platelet-rich plasma (PRP), and biologic scaffolds have been applied with mixed results. Adipose allograft matrix (AAM), which recruits native cells to damaged tissues, may also be a potential treatment for rotator cuff tears.

Neurophysiological Markers of Regulation Success in Everyday Life in Depression.

Background: Self-regulation often is disrupted in depression and is characterized by negative affect and inflexible parasympathetic responses. Yet, our understanding of brain mechanisms of self-regulatory processes largely has been limited to laboratory contexts. Measuring individual differences in self-regulatory processes in everyday life - and their neural correlates - could inform our understanding of depression phenotypes and reveal novel intervention targets that impact everyday functioning.

The impact of neoadjuvant therapy in patients with left-sided resectable pancreatic cancer: an international multicenter study.

Purpose: To assess the association between neoadjuvant therapy and overall survival (OS) in patients with left-sided resectable pancreatic cancer (RPC) compared to upfront surgery.

Background: Left-sided pancreatic cancer is associated with worse OS compared to right-sided pancreatic cancer. Although neoadjuvant therapy is currently seen as not effective in patients with RPC, current randomized trials included mostly patients with right-sided RPC.

The Impact of Antibiotics on Latency When Given at the Time of Membrane Rupture Prior to Viability.

Background: It is well established that antibiotics administered in preterm prelabor rupture of membranes increases latency to delivery. While data is limited for membrane rupture prior to viability, antibiotics may also increase latency in this population.

Objective: To assesses the effect of prophylactic antibiotics on the duration of latency in individuals with previable prelabor rupture of membranes.

From "isolation" to "me-time": linguistic shifts enhance solitary experiences.

Spending time alone is a virtually inevitable part of daily life that can promote or undermine well-being. Here, we explore how the language used to describe time alone - such as "me-time", "solitude", or "isolation" - influences how it is perceived and experienced. In Study 1 ( = 500 U.

A descriptive study of fatal drownings among children and adolescents in the United States, with a focus on retention pond deaths, 2004-2020.

The objective of this study was to characterize fatal drownings among children and adolescents, with a focus on retention pond drownings, and identify risk factors for these fatalities using child death review data. We acquired 2004-2020 National Fatality Review-Case Reporting System data for drowning deaths among youth 0-19 years. Retention pond drownings were identified through case narratives.

Evolutionary lineage-specific genomic imprinting at the ZNF791 locus.

Genomic imprinting is an epigenetic process that results in parent-of-origin effects on mammalian development and growth. Research on genomic imprinting in domesticated animals has lagged due to a primary focus on orthologs of mouse and human imprinted genes. This emphasis has limited the discovery of imprinted genes specific to livestock.

Fission yeast GPI inositol deacylase Bst1 regulates ER-Golgi transport and functions in late stages of cytokinesis.

The Munc13/UNC-13 family protein Ync13 is essential for septum integrity and cytokinesis in fission yeast. To further explore the mechanism of Ync13 functions, spontaneous suppressors of mutants, which can suppress the colony-formation defects and lysis phenotype of mutant cells, are isolated and characterized. One of the suppressor mutants, -, shows defects in the cytokinetic contractile ring constriction, septation, and daughter-cell separation, similar to mutant.

Impact of Frailty on Surgical Outcomes of Patients With Cushing Disease Using the Multicenter Registry of Adenomas of the Pituitary and Related Disorders Registry.

Background And Objectives: Despite growing interest in how patient frailty affects outcomes (eg, in neuro-oncology), its role after transsphenoidal surgery for Cushing disease (CD) remains unclear. We evaluated the effect of frailty on CD outcomes using the Registry of Adenomas of the Pituitary and Related Disorders (RAPID) data set from a collaboration of US academic pituitary centers.

Methods: Data on consecutive surgically treated patients with CD (2011-2023) were compiled using the 11-factor modified frailty index.

Technical considerations of cardiac computed tomography in children.

Cardiac computed tomography angiography (CTA) is a valuable tool in the assessment of congenital and acquired cardiac disease in children. The goal of cardiac CTA is to produce images that are free of motion and provide sufficient characterization of the anatomy in question. Given the complexity of pediatric patient characteristics, including patient size, heart rate, breath-holding capability, and variant anatomy, cardiac CTA technique must be individualized to the patient as well as the indication to answer the clinical question while also minimizing radiation exposure.

Challenges in determining the global burden of non-malignant central nervous system tumors: an analysis of international incidence and mortality data sources.

Background: Non-malignant tumors of the CNS contribute substantially to the morbidity and mortality from CNS tumors. It is critical to understand the epidemiology of non-malignant CNS tumors separately from CNS malignancies to inform resource allocation and policy since treatment and prognosis can differ. High quality international data on non-malignant CNS tumor burden are needed to accomplish this goal.

TopMT-GAN: a 3D topology-driven generative model for efficient and diverse structure-based ligand design.

Recent advancements in 3D structure-based molecular generative models have shown promise in expediting the hit discovery process in drug design. Despite their potential, efficiently generating a focused library of candidate molecules that exhibit both effective interactions and structural diversity at a large scale remains a significant challenge. Moreover, current studies often lack comprehensive comparisons to high-throughput virtual screening methods, resulting in insufficient evaluation of their effectiveness.

Non-stationary Domain Generalization: Theory and Algorithm.

Although recent advances in machine learning have shown its success to learn from independent and identically distributed (IID) data, it is vulnerable to out-of-distribution (OOD) data in an open world. Domain generalization (DG) deals with such an issue and it aims to learn a model from multiple source domains that can be generalized to unseen target domains. Existing studies on DG have largely focused on stationary settings with homogeneous source domains.

Targeting the Type I Interferon Pathway in Glomerular Kidney Disease: Rationale and Therapeutic Opportunities.

Type I interferons (IFNs) are immunostimulatory molecules that can activate the innate and adaptive immune systems. In cases of immune dysfunction, prolonged activation of the type I IFN pathway has been correlated with kidney tissue damage in a wide range of kidney disorders, such as lupus nephritis (LN) and focal segmental glomerulosclerosis (FSGS). Genetic mutations, such as risk variants in conjunction with elevated type I IFN expression, are also associated with higher rates of chronic kidney disease in patients with LN and collapsing FSGS.
