Mural cells are essential for maintaining the proper functions of microvasculatures. However, a key challenge of microvascular tissue engineering is identifying a cellular source for mural cells. We showed that , circulating fibrocytes (CFs) can (1) shear and stabilize the microvasculatures formed by vascular endothelial cells (VECs) in a collagen gel, (2) form gap junctions with VECs and (3) induce basement membrane formation.

Background: In the early 1940s, before antihypertensive drugs were available, the Rice Diet Programme (RDP) was developed to treat severe hypertension and, later, diabetes and obesity. Despite significant advancements in dietary management for these conditions since then, debates remain regarding the proper guidelines for sodium and macronutrients intakes. The patient care records of RDP offer a unique source of longitudinal examination of a very low sodium (<10 mmol/day), fat, cholesterol and protein diet on blood pressure (BP), other health markers and survival.

CAR-T cell therapy has revolutionized immunotherapy but its allogeneic application, using various strategies, faces significant challenges including graft-versus-host disease and graft rejection. Recent advances using Virus Specific T cells to generate CAR-VST have demonstrated potential for enhanced persistence and antitumor efficacy, positioning CAR-VSTs as a promising alternative to conventional CAR-T cells in an allogeneic setting. This review provides a comprehensive overview of CAR-VST development, emphasizing strategies to mitigate immunogenicity, such as using a specialized TCR, and approaches to improve therapeutic persistence against host immune responses.

Introduction: The regulation of expression during T-cell development and immune responses is essential for proper lineage commitment and function in the periphery. However, the mechanisms of genetic and epigenetic regulation are complex, and their interplay not entirely understood. Previously, we demonstrated the need for CD4 upregulation during positive selection to ensure faithful commitment of MHC-II-restricted T cells to the CD4 lineage.

Background: We previously reported that machine learning could be used to predict conversion to psychosis in individuals at clinical high risk (CHR) for psychosis with up to 90% accuracy using the North American Prodrome Longitudinal Study-3 (NAPLS-3) dataset. A definitive test of our predictive model that was trained on the NAPLS-3 data, however, requires further support through implementation in an independent dataset. In this report we tested for model generalization using the previous iteration of NAPLS-3, the NAPLS-2, using the identical machine learning algorithms employed in our previous study.

Plastic pollution, particularly microplastics (MPs), poses a significant global threat to ecosystems and human health, necessitating innovative remediation strategies. Biocompatible and biodegradable plastic-binding peptides (PBPs) offer a potential solution through targeted adsorption and subsequent MP detection or removal from the environment. A challenge in discovering plastic-binding peptides is the vast combinatorial space of possible peptides (, over 10 for 12-mer peptides), which far exceeds the sample sizes typically reachable by experiments or biophysics-based computational methods.

Coronary artery disease (CAD) remains the leading cause of death globally, highlighting the critical need for accurate diagnostic tools in medical imaging. Traditional segmentation methods for coronary angiograms often struggle with vessel discontinuity and inaccuracies, impeding effective diagnosis and treatment planning. To address these challenges, we developed the Local Adaptive Segmentation Framework (LASF), enhancing the YOLOv8 architecture with dilation and erosion algorithms to improve the continuity and precision of vascular image segmentation.

The Bartonella genus of bacteria encompasses ubiquitous species, some of which are pathogenic in humans and animals. Bartonella henselae, the causative agent of Cat Scratch disease, is responsible for a large portion of human Bartonella infections. These bacteria can grow outside of cells, replicate in erythrocytes and invade endothelial and monocytic cells.

γ-Glutamyl carboxylase (GGCX) is the sole identified enzyme that uses vitamin K (VK) as a cofactor in humans. This protein catalyses the oxidation of VK hydroquinone to convert specific glutamate residues to γ-carboxyglutamate residues in VK-dependent proteins (VDPs), which are involved in various essential biological processes and diseases. However, the working mechanism of GGCX remains unclear.

Carbon-hydrogen (C-H) bonds are the foundation of essentially every organic molecule, making them an ideal place to do chemical synthesis. The key challenge is achieving selectivity for one particular C(sp)-H bond. In recent years, metalloenzymes have been found to perform C(sp)-H bond functionalization.

Three-dimensional diffractive acoustic tomography.

Nat Commun

January 2025

Department of Biomedical Engineering, Duke University, Durham, NC, USA.

Acoustically probing biological tissues with light or sound, photoacoustic and ultrasound imaging can provide anatomical, functional, and/or molecular information at depths far beyond the optical diffusion limit. However, most photoacoustic and ultrasound imaging systems rely on linear-array transducers with elevational focusing and are limited to two-dimensional imaging with anisotropic resolutions. Here, we present three-dimensional diffractive acoustic tomography (3D-DAT), which uses an off-the-shelf linear-array transducer with single-slit acoustic diffraction.

Introduction: Prolonged sitting can acutely reduce working memory (WM) in individuals with overweight and obesity (OW/OB) who show executive function deficits. Interrupting prolonged sitting with brief PA bouts may counter these effects. However, the benefits of such interventions on behavioral and neuroelectric indices of WM and whether neurocognitive responses are associated with postprandial glycemic responses in young and middle-aged adults with OW/OB remain unknown.

The Hhex gene encodes a transcription factor that is important for both embryonic and post-natal development, especially of hematopoietic tissues. Hhex is one of the most common sites of retroviral integration in mouse models. We found the most common integrations in AKXD (recombinant inbred strains) T-ALLs occur 57-61kb 3' of Hhex and activate Hhex gene expression.

Prenatal gene editing for neurodevelopmental diseases: Ethical considerations.

Am J Hum Genet

January 2025

Department of Social Medicine and Center for Bioethics, University of North Carolina at Chapel Hill, Chapel Hill, NC, USA.

Neurodevelopmental diseases (NDDs) are notoriously difficult to treat because clinical symptoms stem from developmental processes that begin before birth. Prenatal gene editing could fill the treatment gap for NDDs by targeting and permanently correcting the genetic variants that underlie these pathogenic developmental processes. At the same time, there is a risk of unintended edits to the fetus or the pregnant person that could result in serious adverse consequences that are difficult, if not impossible, to undo.

Distribution and correlates of long-acting injectable antipsychotic use among community mental health center patients.

Psychiatry Res

South Carolina Department of Mental Health, 220 Executive Dr, Greer, SC 29651, United States; Department of Neuropsychiatry and Behavioral Science, University of South Carolina School of Medicine, 15 Medical Park, Suite 301, Columbia, SC 29203, United States.

Although long-acting injectable antipsychotics (LAIs) are an important pharmaceutical option in the management of schizophrenia and related disorders, little is known about patient characteristics related to LAI use in real-world outpatient settings. We analyzed electronic medical records from 41,401 patients who received psychiatric services from one of 16 regional mental health centers operated by the South Carolina Department of Mental Health in 2022. We compared the use of first- and second-generation LAIs and oral antipsychotics by sociodemographic (age, gender, race/ethnicity, zip code, payment source) and clinical characteristics (psychiatric diagnoses, service use).

The stone marten (Martes foina) is an important species for cytogenetic studies in the order Carnivora. ZooFISH probes created from its chromosomes provided a strong and clean signal in chromosome painting experiments and were valuable for studying the evolution of carnivoran genome architecture. The research revealed that the stone marten chromosome set is similar to the presumed ancestral karyotype of the Carnivora, which added an additional value for the species.
