Efficacy evaluation of a minimally invasive surgical procedure (oblique lateral interbody fusion) for lumbar spinal tuberculosis-retrospective cohort study.

Objective: In the current study, to demonstrate the advantages of oblique lateral interbody fusion (OLIF), we focused on the therapeutics for lumbar spinal tuberculosis with the comparison of three treatments, including anterior approach, posterior approach, and OLIF combined with posterior percutaneous pedicle screw fixation.

Methods: This study included patients with lumbar spinal tuberculosis from July 2015 to June 2018. We divided these patients into three groups: 35 patients underwent an anterior-only approach (Group A), 36 patients underwent a posterior-only approach (Group B), and 31 patients underwent OLIF combined with posterior percutaneous pedicle screw fixation (Group C).

IMPDH2 dephosphorylation under FGFR signaling promotes S-phase progression and tumor growth.

Inosine monophosphate dehydrogenase 2 (IMPDH2) is highly expressed in human cancers; however, its physiological relevance under growth signaling remains to be investigated. Here, we show that IMPDH2 serine 122 is phosphorylated by CDK1, and this modification attenuates the catalytic activity of IMPDH2 for IMP oxidation and simultaneously represses its allosteric modulation by purine nucleotides. Fibroblast growth factor receptor (FGFR) signaling activation triggers IMPDH2-Ser122 dephosphorylation mediated by protein phosphatase 2A (PP2A), which is dependent on FGFR3-mediated PPP2R1A-Tyr261 phosphorylation leading to PPP2CA-PPP2R1A-IMPDH2 interactions.

High-intensity strength training improves mobility in patients after hip fracture: A meta-analysis of randomized controlled trials.

Background: Hip fracture affects millions of persons and is associated with excess morbidity and mortality. More knowledge is needed to regard the prolonged effects of intensive exercise in relatively frail hip fracture patients. In this meta-analysis, we want to determine whether intensity strength training in patients after hip fracture is superior to general exercises in improving physical function.

Magnetic soft microrobots for erectile dysfunction therapy.

Erectile dysfunction (ED) is a major threat to male fertility and quality of life, and mesenchymal stromal cells (MSCs) are a promising therapeutic option. However, therapeutic outcomes are compromised by low MSC retention and survival rates in corpus cavernosum tissue. Here, we developed an innovative magnetic soft microrobot comprising an ultrasoft hydrogel microsphere embedded with a magnetic nanoparticle chain for MSC delivery.

Differentiation signals induce APOBEC3A expression via GRHL3 in squamous epithelia and squamous cell carcinoma.

Two APOBEC DNA cytosine deaminase enzymes, APOBEC3A and APOBEC3B, generate somatic mutations in cancer, thereby driving tumour development and drug resistance. Here, we used single-cell RNA sequencing to study APOBEC3A and APOBEC3B expression in healthy and malignant mucosal epithelia, validating key observations with immunohistochemistry, spatial transcriptomics and functional experiments. Whereas APOBEC3B is expressed in keratinocytes entering mitosis, we show that APOBEC3A expression is confined largely to terminally differentiating cells and requires grainyhead-like transcription factor 3 (GRHL3).

Plasma exchange as an effective treatment for cytokine release syndrome following T cell receptor‑engineered T cell immunotherapy: A case report.

T-cell receptor-engineered T-cell (TCR-T) immunotherapy is a promising approach for the treatment of solid tumors. However, TCR-T therapy can result in severe cytokine release syndrome (CRS), thus limiting its therapeutic application. The present study reported the case of a patient with TCR-T-related CRS, which was treated successfully with plasma exchange (PE).

Ponatinib exacerbate renal injury in systemic lupus erythematosus mouse model through PDGFR-PI3K/AKT pathway.

Lupus nephritis (LN) is a common clinical complication of systemic lupus erythematosus (SLE). Proliferative lupus nephritis represents the gravest form of LN, and since effective drugs for its treatment are still lacking, tyrosine kinase inhibitors (TKIs) find extensive clinical utility due to their notable impact on suppressing cell proliferation and may serve as potential drugs for LN treatment. However, previous studies on the effects of TKI on LN have been controversial.

Three-dimensional (3D) ex vivo cell culture models can facilitate stemness improvement and CSC enrichment. Considering the critical role of extracellular matrix (ECM) on CSC properties, the present study developed a thermo-responsive hydrogel using the porcine decellularized lung for 3D cell culture, and the cell-laden hydrogel culturing model was used to explore the CSC characteristics and potential utilization in CSC-specific drug evaluation.

In vivo biosensing of subcellular pyruvate pools reveals photosynthesis-dependent metabolite dynamics in Nicotiana benthamiana.

Pyruvate is central to metabolism across biology. It acts as a metabolic hub linking major pathways including glycolysis, the Krebs cycle, fermentation, and synthesis of amino acids, fatty acids, isoprenoids, and nucleotides. Even though the central role of pyruvate is well established biochemically, there is a remarkable gap in our understanding of how pyruvate levels behave within cells, where pyruvate is distributed across different compartments.

3D spheroid culture synchronizes heterogeneous MSCs into an immunomodulatory phenotype with enhanced anti-inflammatory effects.

Mesenchymal stem cells (MSCs) are heterogeneous in morphology and transcriptome, resulting in varying therapeutic outcomes. In this study, we found that 3D spheroid culture of heterogeneous MSCs, which have undergone conventional 2D monolayer culture for 5-6 passages, synchronized the cells into a uniform cell population with dramatically reduced cell size, and considerably increased levels of immunosuppressive genes and growth factors. Single-cell RNA sequencing (scRNA-seq) analysis of the cells revealed that 3D MSCs consisted of 2 major cell subpopulations and both expressed high levels of immunosuppressive factors, compared to 6 subpopulations in 2D MSCs.
