Summary: The oviduct provides ideal conditions for fertilization and early embryonic development, with proper vascularization being essential for its physiological function. This study examined differences in microvascular density across different portions of the equine oviduct and found that angiogenic factors and their receptors are expressed in all studied regions, in line with microvascular patterns.

Summary: This study evaluated the effect of VEGF on neointimal hyperplasia and local inflammatory responses in decellularized small-diameter vascular grafts. The results showed that local administration of VEGF attenuated neointimal hyperplasia by inducing macrophage M2 polarization and modulating the inflammatory response.

Summary: Vascular calcification is common in clinical practice and is associated with adverse events. Oxidative stress plays a role in the formation of vascular calcification. Fibroblast growth factor 21 (FGF21) has been shown to inhibit vascular calcification by restoring the level of antioxidant SOD and reducing oxidative stress. This study provides further evidence for FGF21 as a potential drug for cardiovascular protection.

Summary: The FGF-FGFR signaling pathway and the VEGF-VEGFR signaling pathway play important roles in the treatment of tumors, and inhibitors targeting these two pathways can optimize therapeutic effects and expand the antitumor range. In addition, biomarkers should be developed in the future to predict efficacy, and combination with immune checkpoint inhibitors is a promising direction.

Summary: In this study, it was demonstrated that FGF-2 promotes angiogenesis by activating a SRSF1/SRSF3/SRPK1 network that regulates VEGFR1 alternative splicing in endothelial cells, which could also contribute to lung tumor progression.

Summary: Neuroendocrine neoplasms are tumors originating from neuroendocrine cells in different organs, with dysregulation of receptor tyrosine kinases playing a crucial role in their development and progression. Research on the role of the fibroblast growth factor receptor system in NENs and the potential of FGFR selective inhibitors shows promising anti-tumor activity in advanced NEN patients, with further studies needed for confirmation.

Summary: Myocardial infarction (MI) causes irreversible tissue damage and eventual heart failure. Therapeutic angiogenesis using the neuropeptide catestatin (CST) has shown to restore perfusion in a mouse hind limb ischemia model. CST promotes capillary like tube formation, cell proliferation, and protects cardiomyocytes from apoptosis, indicating its potential as a therapy for MI.

Summary: In this study, a facile strategy was developed to construct a flexible and stretchable glucose sensor for investigating the glucose metabolism mechanism of stretched endothelial cells in hyperglycemia. The GOx@ZIF-8/Au SE sensor was successfully used for monitoring the glucose metabolism of mechanically stimulated cells in hyperglycemia, and it was found that the glucose utilization ability of cells under static conditions is higher than that in the stretched state.

Summary: The study found that hypoxic preconditioning significantly increased the survival rate of primary retinal ganglion cells, with VEGF playing an important regulatory role in this process. Over-inhibition of VEGF negatively impacted the survival of RGCs mediated by hypoxic preconditioning.

Summary: The subacromial bursa, previously considered as friction-reducing tissue, is now recognized for its stem cell potential and ability to enhance the regeneration of adjacent tissues. This review explores the role of bursal inflammation as a pain generator and a potential initiator of healing. Therapeutic targets to overcome bursal inflammation and pain are discussed, and further research is needed to fully understand the interplay between the subacromial bursa and rotator cuff tendons.

Summary: The risk of tendon disorders or ruptures increases with age, and intrinsic fitness also plays a role in affecting tendon properties. Low intrinsic fitness accelerates aging of tendons and leads to further impairment, resulting in decreased healing potential and elasticity.

Summary: The direction of PM screw fixation does not affect the primary stability of osteosynthesis of a posterior malleolus fracture. However, anterior to posterior screw fixation may result in slightly greater movement of the fracture. Anterior to posterior screw fixation could be a minimally invasive but stable surgical strategy for posterior malleolus fractures without significant dislocation.

Summary: This study investigated the interaction between Staphylococcus aureus and osteoblasts or osteocytes during infection. The results showed that osteoblasts can induce an antimicrobial response and eliminate intracellular S. aureus, while osteocytes recruit immune cells and enhance inflammation but have a poor capacity for clearing bacterial infection. Additionally, signals from osteocytes enhance intracellular bacterial clearance by osteoblasts.

Summary: Tendon healing is a major challenge due to its poor blood supply and slow metabolic rate. The disruption of cell-extracellular matrix interactions and uncontrolled inflammation can hinder successful healing. Optimizing Achilles tendon (AT) healing outcomes may involve adapting mechanical stimulation, restricting neoangiogenesis, and modifying stem cell niche parameters.

Summary: Fracture-related infection (FRI) is a common complication of bone fractures, where pathogenic bacteria enter the wound and hinder the healing process. This Primer provides an overview of the epidemiology, pathobiology, diagnosis, and management of these infections, as well as their impact on patient quality of life.

Summary: In the treatment of ankle fractures, complications related to wound healing after open reduction and internal fixation are a significant issue. A minimally invasive nail stabilization technique has been proposed as an alternative. This biomechanical study aimed to determine if this technique is comparable to the established method. The results showed that both the nail and plate fixations resulted in reduced stability and rotational stiffness compared to the intact ankle. While the nail fixation had greater rotational stiffness, both methods fell short of the native stability. The study suggests that weight-bearing after nail fixation should be evaluated on a case-by-case basis.

Summary: Osteomyelitis, a difficult-to-treat bone infection caused by Staphylococcus aureus, was studied using mouse models. Fluorescence imaging and label-free Raman spectroscopy were used to characterize tissue changes and bacterial localization. The results showed that bacteria formed abscesses in the infected tissue, with lower numbers found in surrounding muscle tissue and trabecular bone tissue. Raman spectroscopic imaging revealed a metabolic state of the bacteria with reduced activity.

Summary: Although prophylactic use of vancomycin is routinely performed after ACL reconstruction, it may potentially harm the tissue and cells. A comprehensive study was conducted to investigate its effect on tendon tissue and isolated tenocytes, and the results demonstrated that vancomycin at clinically used concentrations had no negative impact on cell viability, gene expression, histology, and mechanical integrity.

Summary: Bone defects and infections present challenges for treatment, and this study evaluated the efficacy of different bone allografts in antibiotic absorption and release. The fibrous grafts showed the highest absorption capacity, while mineralized cancellous bone had the lowest absorption capacity. The fibrous grafts also exhibited prolonged antibiotic release and activity, making them suitable carrier grafts for antibiotic administration.

Summary: The hook test is commonly used to assess syndesmosis stability during surgery, but there are no guidelines for the force required or the reliability of the test. In this study, ten experienced surgeons performed hook tests on cadaver bone models, with forces recorded in a blinded manner. Standardized hook tests were also performed on cadaver lower legs, revealing that the force and instability of the syndesmosis significantly influenced syndesmosis diastasis. However, even with maximum instability, only a small percentage of specimens showed significant diastasis (>2 mm). The hook test shows high variability and is not able to detect relevant syndesmosis injuries, even when performed in a standardized manner.
