Summary: Transplantation is limited by the shortage of healthy donor organs, but ex situ machine perfusion has the potential to expand the donor pool. Mesenchymal stem cells are considered as a tool with the potential to improve organs, but clinical benefits have not been conclusively demonstrated.

Summary: This study aimed to achieve stable 24-hour normothermic ex vivo lung perfusion by examining modifications to the perfusate administration in a large animal model. Results showed that modifying the perfusate and adding total parenteral nutrition significantly extended perfusion time, improved lung function, and reduced inflammatory cytokine production compared to the control group. Further research is needed to develop stable lung support beyond 24 hours.

Summary: This study established an ex vivo blood-perfused model for equine uteri and investigated the effects of different cycle stages on the model's applicability. The results showed that the model supported uterine functionality for 6 hours, but viability and histomorphology of the endometrium appeared to be impaired after 4 hours of perfusion. The cycle stage did not affect the applicability of the model.

Summary: Heart transplantation is the most effective treatment for end-stage heart failure, but the number of patients awaiting transplantation is still increasing. The normothermic ex situ preservation technique has been shown to be comparable to traditional cold storage, allowing donor hearts to be preserved for up to 12 hours in a physiological condition. We present a rat model of this technique, which is cost-effective and can be completed by a single experimenter.

Summary: The study found that diesel exhaust particles (DEPs) can accumulate in key cell types of the placental tissue and cross the human placenta, although in limited amounts. These findings are crucial for risk assessment and protection of pregnant women, emphasizing the urgent need for further research on the developmental toxicity of ambient particulates mediated by the placenta, both directly and indirectly.

Summary: The study aims to analyze choroidal vascular density alteration in high myopia with or without choroidal neovascularization using OCTA. Results showed that patients with choroidal neovascularization had higher age, thinner choroidal thickness, and lower choroidal vascular density than those without. Multivariate analysis revealed that decreased choroidal vascular density and older age were independent factors associated with choroidal neovascularization in high myopic eyes.

Summary: This experiment demonstrates the feasibility and benefits of using ILP combined with PET/CT imaging. The results show that ILP can preserve near physiologic gas exchange and glucose metabolism. The peripheral area of the carcinoid exhibits delayed but high somatostatin receptor agonist uptake compared to the surrounding parenchyma and the intrapulmonary artery, while the central area of the carcinoid shows very low uptake.

Summary: This experiment demonstrates the potential and benefits of using isolated lung perfusion (ILP) combined with positron emission tomography-computed tomography (PET/CT) imaging for real-time visualization of tumors in ventilated and perfused lung tissue. The experiment involved a 49-year-old male patient who underwent lung surgery, and the results showed that ILP combined with PET/CT imaging can provide important insights into tumor physiology and molecular imaging.

Summary: Thyroid eye disease (TED) is characterized by enlargement of extraocular muscles, an increase in retrobulbar fat, orbital fibrosis, and fluctuations in plasma thyroid hormone levels in most patients, often associated with raised autoantibody titers. The occurrence of orbital space conflict compromises the orbital perfusion, resulting in irreversible loss of visual acuity and visual fields. Various imaging techniques can be used to assess the orbital and ocular perfusion in TED, including color Doppler imaging, optical coherence tomography angiography, and optical coherence tomography.

Summary: This paper reviews the role of human leukocyte antigen G (HLA-G) in the eye, explores the potential therapeutic applications of AAV gene transfer and expression of HLA-G in different ocular tissues, and discusses the efficacy of these treatments in animal models of various eye diseases. The findings suggest that AAV-HLA-G could be an effective treatment for immune-mediated, inflammatory, and neovascular diseases of the eye.

Summary: The study aimed to assess the transmission of UV radiation through intact enucleated globes of different species using spectrophotometry. The results showed that cats and dogs allowed the most transmission of UV radiation, while pigs and humans allowed the least. A small amount of transmission was detected in the globes of rabbits and horses. These findings will support further vision research for training companion, working, and service animals.

Summary: The study aimed to investigate the effect of gentamicin on CD3+ T-lymphocyte proliferation and cell viability using an in vitro cell culture model. Three adult horses were used for the experiment. Peripheral blood lymphocytes were treated with different concentrations of gentamicin and stimulated to proliferate. Live cell counts and fluorescent intensity data were collected. Statistical analysis showed no significant differences between gentamicin concentrations or formulations in terms of cell viability and proliferation. The results suggest that low-dose intravitreal gentamicin may not suppress the immune response.

Summary: This study evaluated the efficacy of adeno-associated virus (AAV) gene therapy encoding human leukocyte antigen G (HLA-G) to inhibit ocular graft versus host disease (OGvHD). The results showed that eyes treated with AAV had significantly reduced clinical signs of OGvHD and lower limbal mononuclear cell count. These findings support the potential of HLA-G-based gene therapy as an effective treatment for OGvHD.

Summary: This study aims to explore the differences in fungal response to topical antifungal treatment at different stages of fungal keratitis (FK) development. The results show that fungal development stage is correlated with efficacy, and traditional antifungal susceptibility testing methods are not applicable to more advanced developmental stages. A revised method of antifungal susceptibility testing may better predict fungal response in the clinical setting.

Summary: Deficiency and dysfunction of corneal cells can lead to blindness in corneal diseases. However, there is a lack of adequate cell sources for regenerative cell therapies and engineered corneal tissue. The discovery of induced pluripotent stem cells (iPSCs) provides an opportunity to generate corneal cells autologously and in unlimited quantities. iPSCs have advantages over other stem cell sources in terms of differentiation potential and ethical concerns. They have been used to model corneal disorders and diseases, perform drug testing, and explore regenerative medicine. Building stem cell banks with HLA-homozygous cell lines can provide cost- and time-efficient allogeneic alternatives to expensive autologous treatments.
