Article Abstract
Acute respiratory distress syndrome (ARDS) is a severe complication of lung injury characterized by hyperinflammation and fibrosis. Here, we show a significant association between the monocyte-derived enzyme adenosine deaminase 2 (ADA2) and SARS-CoV-2 induced ARDS. We note an interesting link between ADA2 and the chemokine CXCL10 and its receptor CXCR3. By using published datasets of spatial transcriptomics and single-cell RNAseq, we show that ADA2 is highly expressed by inflammatory CD14CD16 monocytes, along with profibrotic genes, in lungs affected by COVID-19. This study reveals important associations between key pathophysiological features of ARDS, linking hypoxia, infiltrative CXCR3 monocytes, and a monocyte-derived exoenzyme ADA2.

Mutations in the human ADAR gene encoding adenosine deaminase acting on RNA 1 (ADAR1) cause Aicardi-Goutières syndrome 6 (AGS6); a severe auto-inflammatory encephalopathy with aberrant interferon (IFN) induction. AdarΔ2-13 null mutant mouse embryos lacking ADAR1 protein die with high levels of IFN-stimulated gene (ISG) transcripts. In Adar Mavs double mutants also lacking the Mitochondrial antiviral signaling (MAVS) adaptor, the aberrant IFN induction is prevented.

This study investigated the impact of cold water with increasing temperature (CI) and boiling water with constant temperature (BC) steaming on the metabolites and taste of Eriocheir sinensis. Sensory evaluation and electronic tongue analysis indicated that CI group enhanced ovaries umami, whereas BC group increased muscle umami (p < 0.05).

Human hematopoietic stem and progenitor cell (HSPC) fitness declines following exposure to stressors that reduce survival, dormancy, telomere maintenance, and self-renewal, thereby accelerating aging. While previous National Aeronautics and Space Administration (NASA) research revealed immune dysfunction in low-earth orbit (LEO), the impact of spaceflight on human HSPC aging had not been studied. To study HSPC aging, our NASA-supported Integrated Space Stem Cell Orbital Research (ISSCOR) team developed bone marrow niche nanobioreactors with lentiviral bicistronic fluorescent, ubiquitination-based cell-cycle indicator (FUCCI2BL) reporter for real-time HSPC tracking in artificial intelligence (AI)-driven CubeLabs.

Objective: To perform an external validation of a previously reported machine learning (ML) approach for predicting the diagnosis of pleural tuberculosis.
Patients And Methods: We defined two cohorts: a Training group, comprising 273 out of 1,220 effusions from our prospective study (2013-2022); and a Testing group, from a retrospective analysis of 360 effusions from 832 consecutive patients in Bajo Deba health district (1996-2012). All the effusions included were exudative and lymphocytic.
Post-transcriptional RNA modifications, such as N6-methyladenosine (m6A) methylation and adenosine to inosine (A-to-I) editing, are critical regulators of hematopoietic stem cell (HSC) self-renewal and differentiation, yet their precise contributions to malignant transformation are not fully elucidated. In this study, we uncovered the epitranscriptomic landscape caused by knockdown of genes from the methyltransferase (METTL)-family in hematopoietic stem and progenitor cells (HSPCs). We identified both converging and distinct roles of METTL3 and METTL14, known members of the m6A writer complex, as well as orphan gene METTL13.
