Vertebroplasty of cervical vertebra.

BACKGROUND: The first vertebroplasty was performed by Harve Deramond in France in 1984 due to a hemangioma of cervical vertebral body. Procedure technique consisted of inserting a needle through the bony palate of the oral cavity. Bone cement injected under pressure not only fills the areas of bone loss. The heat released in the process of crystallization causes denaturation of pathological tissue proteins (metastasis) and disrupts blood supply (hemangiomas). The aim of this study was to evaluate the method of treatment from anterolateral access. MATERIAL/METHODS: In the years 2007-2012 the p

Construction of CXCR4 Receptor-Targeted CuFeSe2 Nano Theranostic Platform and Its Application in MR/CT Dual Model Imaging and Photothermal Therapy.

INTRODUCTION: Targeting, imaging, and treating tumors represent major clinical challenges. Developing effective theranostic agents to address these issues is an urgent need. METHODS: We introduce an "all-in-one" tumor-targeted theranostic platform using CuFeSe2-based composite nanoparticles (CuFeSe2@PA) for magnetic resonance (MR) and computed tomography (CT) dual model imaging-guided hyperthermia tumor ablation. Plerixafor (AMD3100) is bonded to the surface of CuFeSe2 as a targeting unit. Due to the robust interaction between AMD3100 and the overexpressed Chemokine CXC type receptor 4 (CXCR4

Earlier onset of chemotherapy-induced neuropathic pain in females by ICAM-1-mediated accumulation of perivascular macrophages.

Sex differences in the pathogenesis of a variety of diseases have drawn increasing attention. However, it remains unclear whether such differences exist in chemotherapy-induced neuropathic pain. Here, we conducted a retrospective analysis of clinical case data and found that peripheral sensory disorders occurred earlier in females than in males following bortezomib (BTZ) treatment in patients with multiple myeloma. BTZ treatment led to an early elevation of intercellular adhesion molecule-1, which triggered the infiltration of peripheral monocytes into the perivascular region of the spinal cor

Alendronate-coated long-circulating liposomes containing 99mtechnetium-ceftizoxime used to identify osteomyelitis.

Osteomyelitis is a progressive destruction of bones caused by microorganisms. Inadequate or absent treatment increases the risk of bone growth inhibition, fractures, and sepsis. Among the diagnostic techniques, functional images are the most sensitive in detecting osteomyelitis in its early stages. However, these techniques do not have adequate specificity. By contrast, radiolabeled antibiotics could improve selectivity, since they are specifically recognized by the bacteria. The incorporation of these radiopharmaceuticals in drug-delivery systems with high affinity for bones could improve the

Development and comparison of 68Ga/18F/64Cu-labeled nanobody tracers probing Claudin18.2.

Claudin 18.2 (CLDN18.2) is an emerging target for the treatment of gastric cancers. We aim to develop tracers to image the expression of CLDN18.2. A humanized nanobody targeting CLDN18.2 (clone hu19V3) was produced and labeled with 68Ga, 64Cu, and 18F. The tracers were investigated in subcutaneous and metastatic models established using two different mouse types (nude and Balb/c mice) and two different cell lines (CHO-CLDN18.2 and CT26-CLDN18.2). Gastric cancer patient-derived xenograft (PDX) models were further established for validation experiments. Three novel CLDN18.2-targeted tracers (i.e

Intrinsic retinoic acid synthesis is required for oligodendrocyte progenitor expansion during CNS remyelination.

Myelin regeneration (remyelination) in the CNS depends on the recruitment, proliferation and differentiation of oligodendrocyte precursor cells (OPCs) at demyelinated lesions. However, despite the presence of OPCs, very few oligodendrocytes and myelin are regenerated in chronic multiple sclerosis (MS) lesions for reasons that remain poorly understood. Here, using a spontaneous remyelination model in mice, we found that retinaldehyde dehydrogenase 2 (Raldh2), a rate-limiting enzyme for retinoic acid (RA) synthesis, is upregulated in OPCs and in a subpopulation of microglia/macrophages during re

Recent advances in biomimetic nanodelivery systems for cancer Immunotherapy.

Tumor immunotherapy is a developing and promising therapeutic method. However, the mechanism of tumor immune microenvironment and individual differences of patients make the clinical application of immunotherapy still very limited. The resulting targeting of the tumor environment and immune system is a suitable strategy for tumor therapy. Biomimetic nanodelivery systems (BNDS) coated with nanoparticles has brought new hope for tumor immunotherapy. Due to its high targeting, maximum drug delivery efficiency and immune escape, BNDS has become one of the options for tumor immunotherapy in the fut

Radiocopper in BCMA-targeted immunotheranostics of myeloma.

BACKGROUND: The theranostic potential of copper-64 (PET imaging) and copper-67 (SPECT imaging and therapy) is increasingly recognized. This work investigates the performance of this 'true' matched pair in a preclinical radioimmunotheranostic setting that utilizes experimental monoclonal antibodies (mAbs) directed against B cell maturation antigen (BCMA), a transmembrane glycoprotein that has emerged as a critical target for the treatment of multiple myeloma (MM). METHODS: The commercially available BCMA-directed mAbs MAB193 and Vicky-1 were modified with the bispidine N2py4 enabling chelation

The novel role of circular RNA ST3GAL6 on blocking gastric cancer malignant behaviours through autophagy regulated by the FOXP2/MET/mTOR axis.

Gastric cancer (GC) ranks third in mortality among all cancers worldwide. Circular RNAs (circRNAs) play an important role in the occurrence and development of gastric cancer. Forkhead box P2 (FOXP2), as a transcription factor, is closely associated with the development of many types of tumours. However, the regulatory network between FOXP2 and circRNAs remains to be explored. In our study, circST3GAL6 was significantly downregulated in GC and was associated with poor prognosis in GC patients. Overexpression of circST3GAL6 inhibited the malignant behaviours of GC cells, which was mediated by in
