Sialic acid aptamer and RNA in situ hybridization-mediated proximity ligation assay for spatial imaging of glycoRNAs in single cells.

Glycosylated RNAs (glycoRNAs) have recently emerged as a new class of molecules of substantial interest owing to their potential roles in cellular processes and diseases. However, studying glycoRNAs is challenging owing to the lack of effective research tools including, but not limited to, imaging techniques to study the spatial distribution of glycoRNAs. Recently, we reported the development of a glycoRNA imaging technique, called sialic acid aptamer and RNA in situ hybridization-mediated proximity ligation assay (ARPLA), to visualize sialic acid-containing glycoRNAs with high sensitivity and specificity.

Investigation of the Thermal Stability and Hydrolytic Degradation Kinetics of Poly(Lactide-co-Glycolide) Melts.

Poly(lactide-co-glycolide) (PLGA) is widely used in a variety of long-acting injectables. However, its biodegradable nature creates potential chemical stability challenges during melt extrusion, where PLGA is exposed to elevated temperature (100-140 °C) for several minutes. This study evaluated the thermal stability of three PLGA grades (Resomer® 502, 502H, and 505) with varying molecular weights and chain-ends using a differential scanning calorimeter and twin-screw extruder.

I love you no matter what: Negative relationship quality and daily encounters in the parent-child tie and their implications for daily mood across the lifespan.

Parent-child relationship quality has critical implications for parental emotional well-being across the lifespan. The present study assessed how relationship quality is related to daily encounters between parents and children, how those encounters are linked with parents' mood, and how these associations vary by age. Participants (N = 129, ages 33-91) reported baseline relationship quality with a total of 337 children (ages 1-69).

Primer on Health Equity Research in Health Economics and Outcomes Research: An ISPOR Special Interest Group Report.

Objectives: Disparities in health and healthcare between more and less socially advantaged groups are pervasive, multidimensional, and far-reaching. The material and social conditions in which people are born, grow, work, live, and age are systematically associated with their health and with the volume, quality, and outcomes of care received by the vast majority of the general population, as well as by specific marginalized populations. The field of health economics and outcomes research (HEOR) has an important role in supporting health equity goals.

Methods: We used data from the U.

DNA targeting by compact Cas9d and its resurrected ancestor.

Type II CRISPR endonucleases are widely used programmable genome editing tools. Recently, CRISPR-Cas systems with highly compact nucleases have been discovered, including Cas9d (a type II-D nuclease). Here, we report the cryo-EM structures of a Cas9d nuclease (747 amino acids in length) in multiple functional states, revealing a stepwise process of DNA targeting involving a conformational switch in a REC2 domain insertion.

Endothelial-secreted Endocan activates PDGFRA and regulates vascularity and spatial phenotype in glioblastoma.

Extensive neovascularization is a hallmark of glioblastoma (GBM). In addition to supplying oxygen and nutrients, vascular endothelial cells provide trophic support to GBM cells via paracrine signaling. Here we report that Endocan (ESM1), an endothelial-secreted proteoglycan, confers enhanced proliferative, migratory, and angiogenic properties to GBM cells and regulates their spatial identity.

Targeted inhibition of Aurora kinase A promotes immune checkpoint inhibition efficacy in human papillomavirus-driven cancers.

Background: Human papillomavirus (HPV)-driven cancers include head and neck squamous cell carcinoma and cervical cancer and represent approximately 5% of all cancer cases worldwide. Standard-of-care chemotherapy, radiotherapy, and immune checkpoint inhibitors (ICIs) are associated with adverse effects and limited responses in patients with HPV-driven cancers. The integration of targeted therapies with ICIs may improve outcomes.

Everything feels just a little heavier, more wrought with implications, you know? - a mixed-methods study examining lifestyle behaviors, health, and well-being of pregnant and postpartum women during the early months of the COVID-19 pandemic.

Background: While the striking impact of the COVID-19 pandemic on mental health, heath care access and lifestyle behaviors, including perceived health, diet, physical activity, and sleep has been reported, few studies have examined these domains jointly among pregnant and postpartum people in the early stages of the COVID-19 pandemic.

Methods: This mixed methods study was conducted among a subset of participants (n = 22) in a cohort study in Austin, Texas, who were pregnant or had recently delivered when the outbreak occurred. Measures were from the early second trimester up to 6 months postpartum.

Peptide-Aware Chemical Language Model Successfully Predicts Membrane Diffusion of Cyclic Peptides.

Language modeling applied to biological data has significantly advanced the prediction of membrane penetration for small-molecule drugs and natural peptides. However, accurately predicting membrane diffusion for peptides with pharmacologically relevant modifications remains a substantial challenge. Here, we introduce PeptideCLM, a peptide-focused chemical language model capable of encoding peptides with chemical modifications, unnatural or noncanonical amino acids, and cyclizations.

Alignment of Air Pollution Exposure Inequality Metrics with Environmental Justice and Equity Goals in the United States.

A growing literature within the field of air pollution exposure assessment addresses the issue of environmental justice. Leveraging the increasing availability of exposure datasets with broad spatial coverage and high spatial resolution, a number of works have assessed inequalities in exposure across racial/ethnic and other socioeconomic groupings. However, environmental justice research presents the additional need to evaluate exposure inequity-inequality that is systematic, unfair, and avoidable-which may be framed in several ways.

Paid Domestic Work and Depressive Symptoms in Mexico: Results of a National Health Survey.

Paid domestic work (PDW) is an important source of employment for the global female workforce. It is frequently performed under precarious working conditions and occupational risks that are often associated with depressive symptoms (DSs). Although 10% (2.

Examining Virtual Delivery of Strength at Home for Intimate Partner Violence Perpetration.

This study examined the effectiveness of the virtual delivery of the Strength at Home (SAH) intervention program for intimate partner violence in a sample of 605 military veterans across 69 Veterans Affairs (VA) Medical Centers through a national implementation of the program. Outcome measures included physical IPV, psychological IPV, coercive control behaviors, post-traumatic stress disorder (PTSD) symptoms, and alcohol misuse. Significant pre-intervention to post-intervention reductions were found for all the outcomes, with similar effect size estimates relative to a prior investigation of in-person-delivered SAH through the same national VA implementation.

Control of Two Solid Electrolyte Interphases at the Negative Electrode of an Anode-Free All Solid-State Battery based on Argyrodite Electrolyte.

Anode-free all solid-state batteries (AF-ASSBs) employ "empty" current collector with three active interfaces that determine electrochemical stability; lithium metal - Solid electrolyte (SE) interphase (SEI-1), lithium - current collector interface, and collector - SE interphase (SEI-2). Argyrodite LiPSCl (LPSCl) solid electrolyte (SE) displays SEI-2 containing copper sulfides, formed even at open circuit. Bilayer of 140 nm magnesium/30 nm tungsten (Mg/W-Cu) controls the three interfaces and allows for state-of-the-art electrochemical performance in half-cells and fullcells.

Context-dependent decision-making in the primate hippocampal-prefrontal circuit.

What is good in one scenario may be bad in another. Despite the ubiquity of such contextual reasoning in everyday choice, how the brain flexibly uses different valuation schemes across contexts remains unknown. We addressed this question by monitoring neural activity from the hippocampus (HPC) and orbitofrontal cortex (OFC) of two monkeys performing a state-dependent choice task.

The unraveling of a Nobel Prize: How Hermann Muller was awarded the Nobel Prize: A front for eugenics.

This paper asserts that the Nobel Prize for Medicine/Physiology that Hermann J. Muller received in 1946 was a front to enhance the legitimacy, acceptance, and application of eugenics, a strategy to guide the direction and rate of human evolutionary change. Seven of the nine people nominating (1932-1946) Muller were proponents of eugenics with Muller being among the most visible of the scientific leaders.

Essential Competencies in Nursing Leadership From Asian Leaders' Perspectives.
