DNA Methylation signatures underpinning blood neutrophil to lymphocyte ratio during first week of human life

9 months 2 weeks ago
Understanding of newborn immune ontogeny in the first week of life will enable age-appropriate strategies for safeguarding vulnerable newborns against infectious diseases. Here we conducted an observational study exploring the immunological profile of infants longitudinally throughout their first week of life. Our Expanded Program on Immunization - Human Immunology Project Consortium (EPIC-HIPC) studies the epigenetic regulation of systemic immunity using small volumes of peripheral blood...

Development of Subcutaneous Panniculitis-Like T-cell Lymphoma After Immune Checkpoint Inhibitor Treatment

9 months 2 weeks ago
Program death 1 (PD-1) inhibitors such as nivolumab are immune checkpoint inhibitors that have revolutionized the treatment of metastatic melanoma. Despite its success in treating melanoma, immune activation can lead to immune-related adverse effects, which are experienced by half of melanoma patients treated with PD-1 inhibitors. Despite the common frequency of immune-mediated adverse events, the development of a secondary lymphoma is exceedingly rare. We present the case of a 53-year-old woman...

Probing Dermal Immunity to Mycobacteria through a Controlled Human Infection Model

9 months 2 weeks ago
Cutaneous mycobacterial infections cause substantial morbidity and are challenging to diagnose and treat. An improved understanding of the dermal immune response to mycobacteria may inspire new therapeutic approaches. We conducted a controlled human infection study with 10 participants who received 2 × 106 CFUs of Mycobacterium bovis bacillus Calmette-Guérin (Tice strain) intradermally and were randomized to receive isoniazid or no treatment. Peripheral blood was collected at multiple time...

Longitudinal Assessment of Selective Motor Dysfunction in Service Members With Combat-Related Mild TBI

9 months 2 weeks ago
CONCLUSIONS: Assessment of gross motor function reflected a consistent pattern of significantly slower performances for blast and nonblast TBI groups compared to controls, over all follow-up intervals. Fine motor function performance reflected a similar significant difference pattern at 1- and 5-year follow-up intervals, with a reduced difference from control groups at the 10-year follow-up. Maintenance of high-level motor functions, including overall motor speed, coordination, and reaction...

Development and Evaluation of a Real-Time Phase-Triggered Stimulation Algorithm for the CorTec Brain Interchange

9 months 3 weeks ago
With the development and characterization of biomarkers that may reflect neural network state as well as a patient's clinical deficits, there is growing interest in more complex stimulation designs. While current implantable neuromodulation systems offer pathways to expand the design and application of adaptive stimulation paradigms, technological drawbacks of these systems limit adaptive neuromodulation exploration. In this paper, we discuss the implementation of a phase-triggered stimulation...

Exploring Synaptic Pathways in Traumatic Brain Injury: A Cross-Phenotype Genomics Approach

9 months 3 weeks ago
Traumatic brain injury (TBI), a global leading cause of mortality and disability, lacks effective treatments to enhance recovery. Synaptic remodeling has been postulated as one mechanism that influences outcomes after TBI. We sought to investigate whether common mechanisms affecting synapse maintenance are shared between TBI and other neuropsychiatric conditions using pathway enrichment tools and genome-wide genotype data, with the goal of highlighting novel treatment targets. We leveraged an...

HOXD12 defines an age-related aggressive subtype of oligodendroglioma

9 months 3 weeks ago
Oligodendroglioma, IDH-mutant and 1p/19q-codeleted has highly variable outcomes that are strongly influenced by patient age. The distribution of oligodendroglioma age is non-Gaussian and reportedly bimodal, which motivated our investigation of age-associated molecular alterations that may drive poorer outcomes. We found that elevated HOXD12 expression was associated with both older patient age and shorter survival in the TCGA (FDR < 0.01, FDR = 1e-5) and the CGGA (p = 0.03, p < 1e-3). HOXD12...

Rational Design, Synthesis, and Structure-Activity Relationship of a Novel Isoquinolinone-Based Series of HBV Capsid Assembly Modulators Leading to the Identification of Clinical Candidate AB-836

10 months ago
Inhibition of Hepatitis B Virus (HBV) replication by small molecules that modulate capsid assembly and the encapsidation of pgRNA and viral polymerase by HBV core protein is a clinically validated approach toward the development of new antivirals. Through definition of a minimal pharmacophore, a series of isoquinolinone-based capsid assembly modulators (CAMs) was identified. Structural biology analysis revealed that lead molecules possess a unique binding mode, exploiting electrostatic...

Microenvironment T-Type calcium channels regulate neuronal and glial processes to promote glioblastoma growth

10 months ago
CONCLUSIONS: Together these data reveal a role for microenvironment Cav3 in promoting GBM tumor progression through regulating neuronal and glial processes particularly associated with the OPC-cell state. Targeting both intrinsic and microenvironment Cav3 with the inhibitor mibefradil significantly enhanced the anti-GBM effects of TMZ and radiation.

Single-residue effects on the behavior of a nascent polypeptide chain inside the ribosome exit tunnel

10 months ago
Nascent polypeptide chains (NCs) are extruded from the ribosome through an exit tunnel (ET) traversing the large ribosomal subunit. The ET's irregular and chemically complex wall allows for various NC-ET interactions. Translational arrest peptides (APs) bind in the ET to induce translational arrest, a property that can be exploited to study NC-ET interactions by Force Profile Analysis (FPA). We employed FPA and molecular dynamics (MD) simulations to investigate how individual residues placed in...

Analytical Sensitivity Analysis and Clinical Impact Modeling of Rapigen Rapid Diagnostic Tests for Malaria

10 months ago
Laboratory benchmarking allows objective analysis of the analytical performance of malaria rapid diagnostic tests (RDTs). We present the analytical detection limits of the Rapigen BIOCREDIT Malaria Ag Pf/Pv (pLDH/pLDH), the Rapigen BIOCREDIT Malaria Ag Pf (pLDH/HRPII), and two best-in-class WHO-prequalified comparator RDTs, generated using standardized panels containing recombinant antigen, in vitro cultured parasites, international standards, and clinical samples. Detection limit antigen...

Comparative Life Cycle Assessment of alternative winter salad value chains supplying the United Kingdom

10 months ago
Lettuce is an established food commodity in the UK increasingly facing supply challenges in winter due to adverse weather events and rising energy costs. We investigate whether an agroecologically grown salad mix of lettuce and underutilised leafy greens produced in the Azores, Portugal, could be part of a sustainable solution. We performed a Life Cycle Assessment to compare the environmental impacts of this salad mix with four other value chains for winter salad supply to the UK: conventional...

Cholangiocarcinoma

10 months ago
Cholangiocarcinoma (CC) is a heterogeneous group of malignancies that originates at any point along the biliary tree. CC is an uncommon malignancy as it represents approximately 3% of all gastrointestinal malignancies, though its global incidence is rising. CC can often be asymptomatic in its early stages and as a result, it is frequently diagnosed in later stages, leading to challenges in clinical management.
