Exploring Functionally Enhanced BLP‐Trained Macrophage Subpopulations in S. Aureus Infection: Underlying Mechanisms and Therapeutic Significance

open access: yesAdvanced Science, EarlyView.
BLP‐trained macrophages show augmented resistance to infection, but their mechanisms remain unclear. scRNA‐seq identified 13 BMDM subsets, with two novel anti‐inflammatory/antibacterial subpopulations (C5/C7) emerging post‐BLP training. BLP training activates NRF2, attenuates oxidative stress/ferroptosis, and boosts glycolysis/OXPHOS. Adoptive transfer

Depth‐Dependence Changes in Soil Stoichiometry in China's Croplands Over the Past Four Decades

open access: yesAdvanced Science, EarlyView.
This study reveals depth‐dependent changes in soil C:N:P ratios across Chinese croplands over four decades. Changes in stoichiometry vary markedly between topsoil and subsoil, with initial soil C:N:P ratios playing a key role in determining their trajectories.

Three‐Year Follow‐Up of Neoadjuvant Tislelizumab with Chemotherapy in Locally Advanced Gastric and Gastroesophageal Junction Adenocarcinoma: Revealing Cancer‐Associated Fibroblast Heterogeneity Corresponding to PD‐1 Blockade Efficacy

open access: yesAdvanced Science, EarlyView.
Heterogeneous cancer‐associated fibroblasts orchestrate dual immune microenvironments in LAGC. Abstract The potential for immunotherapy in patients with locally advanced gastric cancer (LAGC) is recently confirmed. To report the 3‐year follow‐up data are aimed from a novel clinical trial. This is a prospective single‐arm phase II trial.

Treatment with Minicircle DNA Expressing a FGF23 Fragment in a Clinically relevant Mouse Model of X‐Linked Hypophosphatemic Rickets

open access: yesAdvanced Science, EarlyView.
The pathogenic role of PHEX isn't fully determined, and there is no radical cure for X‐linked hypophosphatemic rickets (XLHR). This study makes the first attempt to perform gene therapy using a minicircle DNA (MC‐DNA) vector expressing a fragment of FGF23 (amino acids 180‐251) in Phex‐T1349C mice and suggests MC‐DNA as a promisingly safe and effective ...

Single‐Cell Dissection Reveals Immune Dysregulation After CD5 or CD7‐Directed Chimeric Antigen Receptor T‐Cell Therapy

open access: yesAdvanced Science, EarlyView.
Single‐cell RNA/TCR/BCR sequencing reveals that 5CAR therapy in T‐ALL induces T‐cell exhaustion, reduces EBV‐associated TCRs, lowers TCR/BCR diversity, and increases NK/DC/monocyte activation and function. In contrast, 7CAR therapy reduces multiple pathogen‐associated TCRs, enhances NK cell activation and function, decreases monocyte activation, and ...

Geometrically Encoded Positioning of Introns, Intergenic Segments, and Exons in the Human Genome

open access: yesAdvanced Science, EarlyView.
This study introduces a new hypothesis: exons, introns, and intergenic segments are non‐random projections of the functional layers of 3D structure of chromatin packing domains. Evidence is presented that this “geometric code” may encode volumetric structure, reconciling epigenetic patterns, correlates with oncogenic mutations, acting as a potential ...

O konformite a autenticite. Náčrt vplyvu fundamentálnej ontológie na dielo Hannah Arendtovej (On Conformity and Authenticity. A Sketch of Fundamental Ontology Influencing the Work of Hannah Arendt)

open access: yesOstium, 2011
The article provides a sketch of Heidegger’s influence on Arendt’s concept of vita activa. The author focuses on the problem of authentic political action and conformity which, despite Arendt’s criticism towards certain elements of fundamental ontology ...

Dysregulation of CircZNF79(5) Modulates YBX1 Stability and Selective Autophagy to Drive Hepatocellular Carcinoma Progression

open access: yesAdvanced Science, EarlyView.
In HCC, circZNF79(5) binds to YBX1 and functions as an oncogene, recruits BRCC36 to remove K63‐linked ubiquitin chains to stabilize YBX1 protein, and promotes HCC progression via the HIF‐1 signaling pathway. Conversely, circZNF79(5) silencing activates the AMPK/mTOR pathway, inducing p62‐mediated selective autophagic degradation of YBX1.

Medizinische Ontologien: das Ende des MeSH / Medical ontologies: the end of MeSH

open access: yesGMS Medizin – Bibliothek – Information, 2006
Since the beginning of information technology the complexicity of medical questions and medical information management is an important topic which challenges computer scientists.In the eighties of last century artificial intelligence went awry.
