Article Synopsis
  • The study investigates the persistence of germinal centre B cells for over 6 months following HIV Env protein immunization in rhesus monkeys, showing a significant increase in B cells at week 10 compared to conventional methods.
  • Continuous somatic hypermutation of the B cells during the 29-week period indicates ongoing selection pressure, leading to a substantial boost in HIV-neutralizing antibodies after a single booster.
  • Findings suggest that a longer priming strategy can enhance immune memory, allowing B cells to better recognize challenging antigens, potentially improving vaccine efficacy for difficult targets.

The mouse digit tip amputation model is an excellent model of bone regeneration, but its size and shape present an obstacle for biomechanical testing. As a result, assessing the structural quality of the regenerated bone in this model has focused on mineral density and bone architecture analysis. Here we describe an image-processing based method for assessment of mechanical properties in the regenerated digit by using micro-computed tomography mineral density data to calculate spatially discrete Young's modulus values throughout the entire distal third phalange.

Background: Endogenous expression of L1 mRNA is the first step in an L1-initiated mutagenesis event. However, the contribution of individual cell types to patterns of organ-specific L1 mRNA expression remains poorly understood, especially at single-locus resolution. We introduce a method to quantify expression of mobile elements at the single-locus resolution in scRNA-Seq datasets called Single Cell Implementation to Find Expressed Retrotransposons (SCIFER).

Pseudomonas aeruginosa () is a pathogen causing significant morbidity and mortality, particularly in hospital patients undergoing ventilation and in individuals with cystic fibrosis. Although we and others have investigated mechanisms used by to subvert innate immunity, relatively less is known about the potential strategies used by this bacterium to fight the adaptive immune system and, in particular, T cells. Here, using RAG KO (devoid of 'classical' αβ and γδ TCR T lymphocytes) and double RAG γC KO mice (devoid of T, NK and ILC cells), we demonstrate that the lymphocytic compartment is important to combat (PAO1 strain).

The Case for Medicine-Pediatrics Training in the U.S. Military.

Mil Med

August 2022

Tulane School of Medicine, Internal Medicine-Pediatrics Residency Program, New Orleans, LA 70112, USA.

Residency programs in the combined specialty of Internal Medicine-Pediatrics (Med-Peds) are not offered in the military graduate medical education system despite existing in the civilian sector for over 50 years. This residency consists of 4 years of training and results in the development of board-certified internists and pediatricians who can care for patients from infancy to death. This versatility, combined with an emphasis on the transition from childhood to adulthood, would be valuable to the Military Health System.

Intravenous (IV) administration of antiviral monoclonal antibodies (mAbs) can be challenging, particularly during an ongoing epidemic, due to the considerable resources required for performing infusions. An ebolavirus therapeutic administered via intramuscular (IM) injection would reduce the burdens associated with IV infusion and allow rapid treatment of exposed individuals during an outbreak. Here, we demonstrate how MBP134, a cocktail of two pan-ebolavirus mAbs, reverses the course of disease (Gulu variant) with a single IV or IM dose in non-human primates (NHPs) as late as five days post-exposure.

De novo limb regeneration after amputation is restricted in mammals to the distal digit tip. Central to this regenerative process is the blastema, a heterogeneous population of lineage-restricted, dedifferentiated cells that ultimately orchestrates regeneration of the amputated bone and surrounding soft tissue. To investigate skeletal regeneration, we made use of spatial transcriptomics to characterize the transcriptional profile specifically within the blastema.

Unlabelled: The inhalation of ambient SARS-CoV-2-containing bioaerosols leads to infection and pandemic airborne transmission in susceptible populations. Filter-based respirators effectively reduce exposure but complicate normal respiration through breathing zone pressure differentials; therefore, they are impractical for long-term use.

Objectives: We tested the comparative effectiveness of a prototyped miniaturized electrostatic precipitator (mEP) on a filter-based respirator (N95) via the removal of viral bioaerosols from a simulated, inspired air stream.

Breakthrough gastrointestinal COVID-19 was observed after experimental SARS-CoV-2 upper mucosal infection in a rhesus macaque undergoing low-dose monoclonal antibody prophylaxis. High levels of viral RNA were detected in intestinal sites contrasting with minimal viral replication in upper respiratory mucosa. Sequencing of virus recovered from tissue in 3 gastrointestinal sites and rectal swab revealed loss of furin cleavage site deletions present in the inoculating virus stock and 2 amino acid changes in spike that were detected in 2 colon sites but not elsewhere, suggesting compartmentalized replication and intestinal viral evolution.

There is broad consensus that airborne disease transmission continues to be the thematic focus of COVID-19, the complexities and understanding of which continues to complicate our attempts to control this pandemic. Masking used as both personal protection and source reduction predominates our society at present and, other than vaccination, remains the public health measure that will faithfully reduce aerosol transmission and overall disease burden (Gandhi and Marr, 2021). Early in the advent of the COVID-19 pandemic, and especially after preliminary recognition of airborne transmission, there was considerable efforts in the application of computational fluid dynamics (CFD) modeling aerosols as well as risk models calculations, the products of which were detailed in the literature (Morawska et al.

This commentary explores the neurobiology of spirituality and asks whether it is possible or desirable to apply genetic engineering to increase human spiritual and religious experience - (gene-spirituality) to deal better with the ever-increasing catastrophes that face humanity? Neurological connections between spirituality and reward genes, reward deficiencies (RDS) (hypodopaminergia), the mirror neuron system, and the default mode network are examined. Some interventions from addiction medicine that may be useful to enhance the neuro-spirituality connectome identified as a cornerstone of the Purpose and Meaning of Life as Reward (PMLR) are identified as reasonable targets for interventions to treat RDS and balance DMN activity.
