With the rise of bone tissue engineering (BET), 3D-printed HA/PCL scaffolds for bone defect repair have been extensively studied. However, little research has been conducted on the differences in osteogenic induction and regulation of macrophage (MPs) polarisation properties of HA/PCL scaffolds with different fibre orientations. Here, we applied 3D printing technology to prepare three sets of HA/PCL scaffolds with different fibre orientations (0-90, 0-90-135, and 0-90-45) to study the differences in physicochemical properties and to investigate the response effects of MPs and bone marrow mesenchymal stem cells (BMSCs) on scaffolds with different fibre orientations.

Importance: The impact of adjunctive intra-arterial tenecteplase administration following near-complete to complete reperfusion by endovascular thrombectomy (EVT) for acute ischemic stroke is unknown.
Objective: To assess the efficacy and adverse events of adjunctive intra-arterial tenecteplase in patients with large vessel occlusion stroke who had achieved near-complete to complete reperfusion (defined as a score on the expanded Thrombolysis in Cerebral Infarction [eTICI] scale of 2c to 3) after EVT.
Design, Setting, And Participants: Investigator-initiated, randomized, open-label, blinded outcome assessment trial implemented at 34 hospitals in China among 540 patients with stroke due to proximal intracranial large vessel occlusion within 24 hours of the time they were last known to be well, with an eTICI score of 2c to 3 after EVT, and without prior intravenous thrombolysis.

Importance: Persisting or new thrombi in the distal arteries and the microcirculation have been reported to limit the benefits of successful endovascular thrombectomy for patients with acute ischemic stroke. It remains uncertain whether intra-arterial thrombolysis by urokinase following near-complete to complete reperfusion by thrombectomy improves outcomes among patients with ischemic stroke due to large vessel occlusion.
Objective: To assess the efficacy and adverse events of intra-arterial urokinase after near-complete to complete reperfusion by thrombectomy for acute ischemic stroke due to large vessel occlusion.

The management of diabetic wounds faces significant challenges due to the excessive activation of reactive oxygen species (ROS), dysregulation of the inflammatory response, and impaired angiogenesis. A substantial body of evidence suggests that the aforementioned diverse factors contributing to the delayed healing of diabetic wounds may be associated with impaired autophagy. Impaired autophagy leads to endothelial and fibroblast dysfunction and impedes macrophage phenotypic transformation.

The human skin and oral cavity harbor complex microbial communities, which exist in dynamic equilibrium with the host's physiological state and the external environment. This study investigates the microbial atlas of human skin and oral cavities using samples collected over a 10-month period, aiming to assess how both internal and external factors influence the human microbiome. We examined bacterial community diversity and stability across various body sites, including palm and nasal skin, saliva, and oral epithelial cells, during environmental changes and a COVID-19 pandemic.

Objective: To investigate the reparative effect of hypoxia pretreated hAMSCs on radiation-induced damage to salivary gland function in mice.
Methods: hAMSCs were separated from human amniotic tissues by mechanical and enzymatic digestion methods and a 15 Gy electron beam was used to locally irradiate the neck of mouse to create a salivary gland injury model. The mouse models were randomly divided into four groups: control group, IR+PBS group, IR+Nor group and IR+HP group.

Thyroid hormone (TH) and it most active form triiodothyronine (T3) are crucial in promoting mitochondrial biogenesis and maintaining cellular homeostasis during the stress response, but their role in paraquat (PQ)-induced pulmonary fibrosis isunclear. The aim of this study was to examine whether there was a deficiency of TH in mouse lung tissue after PQ administration, and to explore the effect of T3, and potential mechanisms of action, in alleviation of PQ-induced pulmonary fibrosis. We found that the activity and expression of iodothyronine deiodinase 2 (DIO2), an enzyme that activates TH, were higher in the lungs of patients with pulmonary fibrosis than in controls.

Mycophenolic acid (MPA) is a commonly used immunosuppressant. In the human body, MPA is metabolized into mycophenolic acid 7-O-glucuronide (MPAG) and mycophenolic acid acyl-glucuronide (AcMPAG) mainly through liver glucuronidation, which involves UDP-glucuronosyltransferase (UGTs) and transfer proteins. Research has indicated that the pharmaceutical excipient PEG400 can impact drug processes in the body, potentially affecting the pharmacokinetics of MPA.
