This study investigated the mechanical properties of beech (Fagus sylvatica L.) and fir (Abies alba) wood from Bosnia and Herzegovina under outdoor exposure. Samples were exposed for 3-month exposure to assess bending strength, color changes, and surface quality. Results showed outdoor exposure negatively affected mechanical properties, particularly in samples with extended finger joints, causing significant surface cracks in uncoated sam-ples. Beech wood exhibited notable color changes under exposure, with approximately 50% darkening without coating compared to 25% under covered conditions. Coated samples displayed minimal color changes, affirming the efficacy of surface treatment. Fir wood exhibited a roughness of 8.264 μm, while beechwood average roughness increased from 6.767 to 13.916 μm after exposure, with micro-pore development affecting water perfor-mance. microscopic analysis identified prevalent fungal colonies, including Penicillium, Aureobasidium, Sclerophoma, and Chaetomium, underscoring their role in organic matter decomposition. This study highlights the importance of wood exposure and treatment selection for various applications. © 2024 The Authors.

在实体器官移植中供受者间可能存在疾病传染的问题,因此,用何种方法精确地筛选供者是目前的一大难题。一方面由于病毒感染存在窗口期,传统的血清学检测方法会有假阴性结果,另一方面供者来源的不足、等待移植过程中患者的死亡风险以及移植相关性感染所导致的严重后果等亦对筛选供者的方法提出了挑战,在这种背景下,已广泛用于组织和血液供者筛选的核酸检测(nucleic acid testing,NAT)开始逐渐应用于实体器官移植前供者的筛选和移植后的检测。美国和加拿大的实体器官移植专家通过深入调查研究发现:用NAT来筛选存在感染HIV、HBV或HCV高行为风险因素但可能处于窗口期的供者较之血清学检测更有优势,它可以
