Introducing GPU Acceleration into the Python-Based Simulations of Chemistry Framework.

J Phys Chem A

January 2025

Division of Chemistry and Chemical Engineering, California Institute of Technology, Pasadena, California 91125, United States.

We introduce the first version of GPU4PySCF, a module that provides GPU acceleration of methods in PySCF. As a core functionality, this provides a GPU implementation of two-electron repulsion integrals (ERIs) for contracted basis sets comprising up to functions using the Rys quadrature. As an illustration of how this can accelerate a quantum chemistry workflow, we describe how to use the ERIs efficiently in the integral-direct Hartree-Fock build and nuclear gradient construction.

Prescribing Psychostimulants for the Treatment of Stimulant Use Disorder: Navigating the Federal Legal Landscape.

J Addict Med

January 2025

From the Division of General Internal Medicine, San Francisco General Hospital, Department of Medicine, University of California San Francisco, San Francisco, CA (LWS); San Francisco Department of Public Health, San Francisco, CA (POC); Vital Strategies, New York, NY (KB, DC); Network for Public Health Law, Edina, MN (CSD); and New York University Grossman School of Medicine, New York, NY (CSD).

Stimulant use disorder (StUD) is a rapidly growing concern in the United States, with escalating rates of death attributed to amphetamines and cocaine. No medications are currently approved for StUD treatment, leaving clinicians to navigate off-label medication options. Recent studies suggest that controlled prescription psychostimulants such as dextroamphetamine, methylphenidate, and modafinil are associated with reductions in self-reported stimulant use, craving, and depressive symptoms.

Impact of Subsurface Oxygen on CO Charging Energy Changes in Cu Surfaces.

J Phys Chem Lett

January 2025

Department of Chemistry and Biochemistry, University of California, Santa Barbara, Santa Barbara, California 93106, United States.

Subsurface oxygen in oxide-derived copper catalysts significantly influences CO activation. However, its effect on the molecular charging process, the key to forming the CO intermediate, remains poorly understood. We employ many-body perturbation theory to investigate the impact of the structural factors induced by the subsurface oxygen on the charged activation of CO.

Greenhouse Gas Emissions and Decarbonization Potential of Global Fired Clay Brick Production.

Environ Sci Technol

January 2025

Laboratory of Construction Materials, École Polytechnique Fédérale de Lausanne, CH-1015 Lausanne, Switzerland.

Fired clay bricks (FCBs) are a dominant building material globally due to their low cost and simplicity of production, especially in low- and middle-income countries. With a projected rising housing demand, commensurate growth in brick demand is anticipated, the production of which could result in significant greenhouse gas (GHG) emissions. Robust models are needed to estimate brick demand and emissions to systematically address decarbonization pathways.

The structural and chemical properties of metal nanoparticles are often dictated by their interactions with molecular ligand shells. These interactions are highly material-specific and can vary significantly even among elements within the same group or materials with similar crystal structure. In this study, we surveyed the heterogeneous interactions between an -terphenyl isocyanide ligand and Au and Ag nanoparticles (NPs) at the single-molecule limit.

Per- and polyfluoroalkyl substances (PFAS)-containing firefighting foam have been used in stationary fire suppression systems for several decades. However, there is a lack of research on how to decontaminate PFAS-contaminated infrastructure and evaluate treatment efficiency. This study assessed the removal of PFAS from stainless steel pipe surfaces using different cleaning agents (tap water, methanol, and aqueous solutions containing 10 and 20 wt % of butyl carbitol (BC)) at different temperatures (20 °C, 40 °C, and 70 °C).

Background: Neck ultrasound (US) and serum thyroglobulin (Tg) measurements are mainstays of long-term differentiated thyroid cancer (DTC) surveillance. Given the high sensitivity of serum Tg, we aimed to assess the utility of neck US in DTC patients who underwent total thyroidectomy and have undetectable serum Tg.

Methods: We performed a retrospective cohort analysis of DTC patients who underwent a total thyroidectomy at our institution (2010-2023) and received US-guided fine needle aspiration (FNA) during their surveillance.

Diabetes mellitus can cause impaired and delayed wound healing, leading to lower extremity amputations; however, the mechanisms underlying the regulation of vascular endothelial growth factor-dependent (VEGF-dependent) angiogenesis remain unclear. In our study, the molecular underpinnings of endothelial dysfunction in diabetes are investigated, focusing on the roles of disabled-2 (Dab2) and Forkhead box M1 (FOXM1) in VEGF receptor 2 (VEGFR2) signaling and endothelial cell function. Bulk RNA-sequencing analysis identified significant downregulation of Dab2 in high-glucose-treated primary mouse skin endothelial cells.

Pediatric high-grade gliomas (pHGGs) are the most aggressive brain tumors in children, necessitating innovative therapies to improve outcomes. Unlike adult gliomas, recent research reveals that childhood gliomas have distinct biological features, requiring specific treatment strategies. Here, we focused on deciphering unique genetic dependencies specific to childhood gliomas.

Genomic sequencing in diverse and underserved pediatric populations: parent perspectives on understanding, uncertainty, psychosocial impact, and personal utility of results.

Genet Med

January 2025

Genomics Ethics, and Translational Research Program, RTI International, Research Triangle Park, NC; Department of Translational and Applied Genomics, Kaiser Permanente Center for Health Research, Portland, OR. Electronic address:

Purpose: Limited evidence evaluates parents' perceptions of their child's clinical genomic sequencing (GS) results, particularly among individuals from medically underserved groups. Five Clinical Sequencing Evidence-Generating Research (CSER) consortium studies performed GS in children with suspected genetic conditions with high proportions of individuals from underserved groups to address this evidence gap.

Methods: Parents completed surveys of perceived understanding, personal utility, and test-related distress after GS result disclosure.

BaNDyT: Bayesian Network Modeling of Molecular Dynamics Trajectories.

J Chem Inf Model

January 2025

Department of Computational and Quantitative Medicine, Beckman Research Institute of the City of Hope, 1218 S 5th Ave, Monrovia, California 91016, United States.

Bayesian network modeling (BN modeling, or BNM) is an interpretable machine learning method for constructing probabilistic graphical models from the data. In recent years, it has been extensively applied to diverse types of biomedical data sets. Concurrently, our ability to perform long-time scale molecular dynamics (MD) simulations on proteins and other materials has increased exponentially.

Objective: Patients with uncontrolled gout have few treatment options. Pegloticase lowers serum urate (SU) levels, but antidrug antibodies limit SU-lowering response and increase infusion reaction (IR) risk. Methotrexate (MTX) cotherapy increases pegloticase response rates and lowers IR risk in pegloticase-naïve patients.

Metabolic and Immune Diseases Department, Biomedical Research Institute Sols-Morreale (IIBM), National Research Council (CSIC), Autonoma University of Madrid, Spain (T.A.-G., S.M.-T., R.C.-M., S.U.-B., S.M.-P.).

Background: Hypoxia is associated with the onset of cardiovascular diseases including cardiac hypertrophy and pulmonary hypertension. HIF2 (hypoxia-inducible factor 2) signaling in the endothelium mediates pulmonary arterial remodeling and subsequent elevation of the right ventricular systolic pressure during chronic hypoxia. Thus, novel therapeutic opportunities for pulmonary hypertension based on specific HIF2 inhibitors have been proposed.

College of Pharmaceutical Sciences, Zhejiang University, 866 Yuhangtang Road, Hangzhou, Zhejiang 310058, P. R. China.

Atopic dermatitis (AD) is a recurrent and chronic inflammatory skin condition characterized by a high lifetime prevalence and significant impairment of patients' quality of life, primarily due to intense itching and discomfort. However, current pharmacological interventions provide only moderate efficacy and are frequently accompanied by adverse side effects. The immune-pathogenesis of AD involves dysregulation of the Th2 immune response and exacerbation of inflammation related to excessive reactive oxygen species (ROS).
