Photodynamic and ferroptosis therapies for cancer treatment are restricted by the scarcity of oxygen and Fe in cancer cells, and the complicated structure of delivery systems. Herein, a red blood cell-derived vehicle (RDV) inherently enriched with hemoglobin co-delivers a photosensitizer, Ce6, and a ferroptosis promoter, sorafenib (SRF) into cancer cells for boosting oxygen and providing iron, which leads to enhanced PDT and stronger ferroptosis therapy. Damage to the RDV membrane under local irradation leads to SRF release at the tumor site for tumor-targeted therapy.

Mesenchymal stem cell (MSCs)-based therapies have shown a promised result for intervertebral disc degeneration (IVDD) treatment. However, its molecular mechanisms remain unclear. Exosomes involve cell-cell communication via transference of its contents among different cells, and the present potential effect on cell death regulation.

Article Synopsis
  • The study investigates bone loss prevalence and risk factors in 1,398 rheumatic patients compared to 302 healthy individuals, collecting demographic data and bone mineral density tests.
  • Results show higher bone loss in young patients with ankylosing spondylosis (AS) and systemic lupus erythematosus (SLE), while older patients with rheumatoid arthritis (RA), osteoarthritis (OA), and SLE face even greater risks compared to healthy individuals.
  • Key findings indicate that age, low body mass index (BMI), and being female are associated with increased bone loss, while factors like dyslipidemia and hyperuricemia may provide some protection against it.

Article Synopsis
  • The study aimed to investigate changes in bone mineral density (BMD) and identify risk factors for osteopenia and osteoporosis among rheumatic patients, involving 1,007 participants.
  • Results showed that significant percentages of older male and postmenopausal female patients had osteoporosis, with a notable prevalence of osteopenia in both genders.
  • Key risk factors linked to lower BMD included older age, a BMI under 18.5 kg/m², female sex, and glucocorticoid use, highlighting the need for increased intervention for those with osteopenia.

Background: Osteosarcoma (OS) is one of the most common types of primary bone tumors which poses negative effects on the bones of both young children and adolescents. LncRNA LINC00472 has been reported to be involved with poor prognostics in breast cancer and ovarian cancer. As a new lncRNA, its role in OS remains to be elusive.

Photothermal therapy (PTT) is a rapidly developing approach for cancer therapy, which has been widely recognized to exert high efficacy as compared to chemotherapy. However, the limited tumour homing property of currently available drug delivery systems (DDSs) is the bottleneck for the efficient delivery of photothermal agents. Here in this study, we surface modified silica nanoparticles (SLN) with the cell membrane (CM) derived from 143B cells to construct a platform (CM/SLN) capable of targeting the homogenous 143B cells.

The present study aimed to detect early changes in the concentration of matrix metalloproteinase-9 (MMP-9), matrix metalloproteinase‑2 (MMP‑2) and tissue inhibitor of metalloproteinase‑1 (TIMP‑1) in a rat model of brain injury combined with traumatic heterotopic ossification (HO). A total of 132 male Sprague‑Dawley rats were used to establish the experimental and control groups. Anatomy and sample collection were conducted on postoperative days 1, 2, 3, 4, 5, 6 and 7.

Both flagellin (fliC) and IL-18 (INF-γ-inducing factor) have been developed as adjuvants for improving immunogenicity in DNA-vaccinated hosts. An HIV-1 gag plasmid encodes a protein harboring broad epitopes for cytotoxic T-lymphocytes. In this study, the immunogenicity of BALB/c mice immunized with an HIV-1 gag plasmid (pVAX/gag) combined with a chimeric plasmid encoding IL-18 fused to flagellin (pcDNA3/IL-18_fliC) or a single plasmid encoding IL-18 (pcDNA3/IL-18) and/or flagellin (pcDNA3/fliC) was assessed.

Background: Approximately 3-5% of patients with melioidosis manifest CNS symptoms; however, the clinical data regarding neurological melioidosis are limited.

Methods And Findings: We established a mouse model of melioidosis with meningitis characterized by neutrophil infiltration into the meninges histologically and B. pseudomallei in the cerebrospinal fluid (CSF) by bacteriological culturing methods.

Many commonly consumed foods, herbs and spices contain a complex array of naturally occurring bioactive molecules called phytochemicals, which may confer health benefits. In this study, the impact of LiuWei Zhuanggu Granules (LWZGG) on mineral metabolism in osteopenia development was evaluated. Results showed that serum estrogen, bone gla protein (BGP), and calcitonin (CT) levels, bone Ca, Zn and Cu levels, femur, lumbar vertebrae and trabecular bone density, tibia maximum stress and maximum bending strength were increased, and serum parathyroid hormone (PTH), serum and urine Ca, Zn and Cu levels were decreased in rat bone.

Background: The neurogenic bladder dysfunction caused by spinal cord injury is difficult to treat clinically. The aim of this research was to establish an artificial bladder reflex arc in rats through abdominal reflex pathway above the level of spinal cord injury, reinnervate the neurogenic bladder and restore bladder micturition.

Methods: The outcome was achieved by intradural microanastomosis of the right T13 ventral root to S2 ventral root with autogenous nerve grafting, leaving the right T13 dorsal root intact.

The aim of the present research is to study the mechanism of cervical nerve compression syndrome of the external intervertebral foramen and its differential diagnosis with cervical spondylosis. Diagnostic treatment with muscle relaxant, vasodilator, neurotrophic medicine and celecoxib (COX)-2 inhibitor were performed in 20 patients with cervical nerve compression syndrome of the external intervertebral foramen and 20 patients with cervical spondylosis confirmed by operation. Diagnostic local block therapy was performed additionally in cases showing little effect after diagnostic treatment.

Article Synopsis
  • - The study investigates the expression of NF-kappaB in normal buccal mucosa versus oral submucous fibrosis (OSF), finding that NF-kappaB is significantly higher in OSF, particularly in specific cell types like fibroblasts and inflammatory cells.
  • - Researchers used primary human buccal mucosal fibroblasts (BMFs) and exposed them to safrole, a compound from betel leaves, which increased NF-kappaB expression in a dose-dependent manner.
  • - Results indicated that the increase in NF-kappaB caused by safrole could be linked to the activation of the ERK and COX-2 pathways, suggesting a mechanism that may explain the role of areca quid chewing in
