Advances in magnetic nanoparticles for molecular medicine.

Chem Commun (Camb)

January 2025

F. Joseph Halcomb III, M. D. Department of Biomedical Engineering, University of Kentucky, Lexington, Kentucky 40536, USA.

Magnetic nanoparticles (MNPs) are highly versatile nanomaterials in nanomedicine, owing to their diverse magnetic properties, which can be tailored through variations in size, shape, composition, and exposure to inductive magnetic fields. Over four decades of research have led to the clinical approval or ongoing trials of several MNP formulations, fueling continued innovation. Beyond traditional applications in drug delivery, imaging, and cancer hyperthermia, MNPs have increasingly advanced into molecular medicine.

Despite being a major target of reconstructive surgery, development of the ear pinna remains poorly studied. Here we provide a cellular characterization of late gestational and postnatal ear pinna development in two rodents and investigate the role of BMP5 in expansion and differentiation of auricular elastic cartilage. We find that ear pinna development is largely conserved between Mus musculus and the highly regenerative Acomys dimidiatus.

Dissecting the biophysical mechanisms of oleate hydratase association with membranes.

Front Mol Biosci

January 2025

Department of Microbiology, Immunology, and Molecular Genetics, University of Kentucky, Lexington, KY, United States.

This study investigates the dynamics of oleate hydratase (OhyA), a bacterial flavoenzyme from , and its interactions with lipid membranes, focusing on the factors influencing membrane binding and oligomerization. OhyA catalyzes the hydration of unsaturated fatty acids, playing a key role in bacterial pathogenesis by neutralizing host antimicrobial fatty acids. OhyA binds the membrane bilayer to access membrane-embedded substrates for catalysis, and structural studies have revealed that OhyA forms oligomers on membrane surfaces, stabilized by both protein-protein and protein-lipid interactions.

Development of a statewide network hub for screening, referral, and enrollment into food as medicine programs across Kentucky.

Front Public Health

January 2025

Department of Dietetics and Human Nutrition, College of Agriculture, Food and Environment, University of Kentucky, Lexington, KY, United States.

Unlabelled: Widespread recognition of food as medicine interventions' role in reducing food insecurity and improving health outcomes has recently emerged. Several states have released In Lieu of Services, state-approved alternative services that may be offered by managed care organizations in place of covered benefits, or 1,115 Medicaid waivers, which may allow for expanded nutrition services to reduce food insecurity and improve health outcomes. However, there are significant gaps in understanding how to create a statewide system for delivering "healthcare by food" interventions.

Understanding species' dietary ecology and interspecific interactions is crucial for multi-species conservation planning. In Central Asia and the Himalayas, wolves have recolonized snow leopard habitats, raising considerable concern about resource competition between these apex predators. Using micro-histological analysis of prey species remains (e.

Accurate staging of nodal involvement in pediatric sarcoma patients is important to determine correct systemic and local therapy, with the goal to reduce subsequent recurrences. However, differences in lymph node staging strategies, definitions, and treatment protocols between the Children's Oncology Group (COG), European paediatric Soft tissue sarcoma Study Group (EpSSG), and the Cooperative Weichteilsarkom Studiengruppe (CWS) complicate comparisons. In this article, we aim to establish internationally recognized recommendations for lymph node assessment and treatment of children and adolescents diagnosed with rhabdomyosarcoma (RMS) and non-rhabdomyosarcoma soft tissue sarcoma (NRSTS) according to the Consensus Conference Standard Operating Procedure methodology.

Accurate prediction of ligand-receptor binding affinity is crucial in structure-based drug design, significantly impacting the development of effective drugs. Recent advances in machine learning (ML)-based scoring functions have improved these predictions, yet challenges remain in modeling complex molecular interactions. This study introduces the AGL-EAT-Score, a scoring function that integrates extended atom-type multiscale weighted colored subgraphs with algebraic graph theory.

Internalizing and externalizing symptoms in individuals with neurofibromatosis type 1: a systematic review and meta-analysis.

Syst Rev

January 2025

Department of Behavioral Sciences and Social Medicine, College of Medicine, Florida State University, 1115 West Call Street, Tallahassee, FL, 32306-4300, USA.

Background: Individuals with neurofibromatosis type 1 (NF1) frequently report psychosocial problems, among which internalizing and externalizing symptoms are the most poorly understood due to limited research and inconsistent evidence. This hinders the overall attendance of their psychosocial needs and has a major impact on their quality of life. Thus, this systematic review and meta-analysis was conducted to synthesize existing findings on the degree to which individuals with NF1 experience internalizing and externalizing symptoms, compared with the unaffected population, and explore moderators of the group disparities.

Streptococcus mutans, the causative agent of human dental caries, expresses a cell wall attached Serotype c-specific Carbohydrate (SCC) that is critical for cell viability. SCC consists of a polyrhamnose backbone of →3)α-Rha(1 → 2)α-Rha(1→ repeats with glucose (Glc) side-chains and glycerol phosphate (GroP) decorations. This study reveals that SCC has one predominant and two more minor Glc modifications.

BCR::ABL1-like B-lymphoblastic leukaemia (B-ALL) neoplasms lack the BCR::ABL1 translocation but have a gene expression profile like BCR::ABL1 positive B-ALL. This includes alterations in cytokine receptors and signalling genes, such as and Cases with CRLF2 rearrangements account for approximately 50% of cases of Philadelphia-like acute lymphoblastic leukaemia (Ph-like ALL), and the frequency of specific genomic lesions varies with ethnicity such that IGH::CRLF2 translocations are more common in Hispanics and Native Americans.We report two cases of BCR::ABL1-like ALL, with significant eosinophilia.

Acute symptomatic seizures, occurring shortly after a central nervous system insult, constitute nearly half of all seizure cases. However, there is a conspicuous absence of clear, comprehensive, and cohesive guidelines for the management of these seizures with antiseizure medications, especially their duration of use. This lack of consensus on the optimal duration of therapy leads to prolonged treatments that may carry adverse consequences.

Malaria rapid diagnostic tests (mRDTs) that detect histidine-rich protein 2 (HRP2) remain the mainstay of falciparum malaria diagnosis in Sub-Saharan Africa. Understanding their test characteristics when used for surveillance in asymptomatic populations is important. We explored the rate of false-positive and false-negative mRDT results among asymptomatic persons >5 years old screened for malaria at schools and clinics in the rural Bagamoyo District using 18S ribosomal RNA real-time polymerase chain reaction (qPCR) as the reference test.

The bone marrow (BM) niche is critical in regulating hematopoiesis, and sexual dimorphism and its underlying mechanism in BM niche and its impact on hematopoiesis are not well understood. We show that male mice exhibited a higher abundance of leptin-receptor-expressing mesenchymal stromal cells (LepR-MSCs) compared to female mice. Sex-mismatched co-culture and BM transplantation showed that the male BM niche provided superior support for in vitro colony formation and in vivo hematopoietic engraftment.

Introduction: Inflammation is a vital immune response, tightly orchestrated through both biochemical and biophysical cues. Dysregulated inflammation contributes to chronic diseases, highlighting the need for novel therapies that modulate immune responses with minimal side effects. While several biochemical pathways of inflammation are well understood, the influence of physical properties such as substrate curvature on immune cell behavior remains underexplored.

F. Joseph Halcomb III, MD, Department of Biomedical Engineering, University of Kentucky, 143 Graham Ave., Lexington, Kentucky, 40506, UNITED STATES.

Brain-computer interfaces (BCIs) offer disabled individuals the means to interact with devices by decoding the electroencephalogram (EEG). However, decoding intent in fine motor tasks can be challenging, especially in stroke survivors with cortical lesions. Here, we attempt to decode graded finger extension from the EEG in stroke patients with left-hand paresis and healthy controls.
