A framework for understanding and investigating polyphosphate-protein interactions.

Many prokaryotic and eukaryotic cells store inorganic phosphate in the form of polymers called polyphosphate (polyP). There has been an explosion of interest in polyP over the past decade, in part due to newly suggested roles related to diverse aspects of human health. The physical interaction of polyP chains with specific proteins has been proposed to regulate cellular homeostasis and modulate signaling pathways in response to environmental changes.

Prevalence of co-occurring conditions among youths receiving treatment with primary anxiety, ADHD, or depressive disorder diagnoses.

Introduction: Anxiety disorders, depressive disorders, and attention-deficit/hyperactivity disorder (ADHD) are some of the most common conditions that youths (<18 years old) receive mental health treatment for. These conditions are associated with high-risk substance use or substance use disorders (SUDs). This study sought to identify the proportion of youths (<18 years old) with anxiety disorders, depressive disorders, or ADHD as a primary diagnosis in community mental health centers (CMHCs) having co-occurring high-risk substance use or a SUD.

Identification of Disease-Relevant, Sex-Based Proteomic Differences in iPSC-Derived Vascular Smooth Muscle Cells.

The prevalence of cardiovascular disease varies with sex, and the impact of intrinsic sex-based differences on vasculature is not well understood. Animal models can provide important insights into some aspects of human biology; however, not all discoveries in animal systems translate well to humans. To explore the impact of chromosomal sex on proteomic phenotypes, we used iPSC-derived vascular smooth muscle cells from healthy donors of both sexes to identify sex-based proteomic differences and their possible effects on cardiovascular pathophysiology.

Selective or routine face mask application for breathing support of preterm infants at birth: a randomised trial.

Background: Most preterm infants breathe spontaneously at birth. Despite this, the majority have a face mask immediately applied for breathing support. Face mask application may inhibit spontaneous breathing in newborn infants.

The impact of age, sex, and gender on polypharmacy and potential prescribing cascades: Lessons from five databases.

Background: Few studies describe how gender-related factors may contribute to polypharmacy and prescribing cascades. Describing these patterns using cross-national comparisons can improve the robustness of findings and provide lessons on the importance of considering age, sex, and gender in pharmacological research. The aim of the study was to explore the intersection of age, sex, and gender with polypharmacy and co-prescribing suggesting a potential prescribing cascade.
