Extraosseous distribution of 99mTc-diphosphonates during bone scintigraphy: review of the literature with case series presentation. 骨闪烁成像中 99mTc 二膦酸盐的骨外分布:文献综述与病例系列介绍。
IF 2.6 4区 医学 Q2 Medicine Pub Date : 2024-01-01 Epub Date: 2023-08-10 DOI: 10.1080/09553002.2023.2242935

Purpose: Technetium-99m (99mTc)-diphosphonates represent the most common radiopharmaceutical used for bone scintigraphy. Even if the uptake in bone tissue has been widely explored, atypical uptake could be seen in soft tissue malignancies during bone scintigraphy. Increased vascularization and endothelium permeability represent front-row players in the biodistribution of the tracer, albeit other causes have been identified such as trauma, necrosis, the presence of calcification in metastasis, the pH of the tissue and consequently the type of ion concentration.

Conclusion: The aim of this paper is to summarize the state of art of atypical soft tissue uptake seen in cancer tissues. The research was conducted on PubMed. The analysis of the literature suggests that calcium metabolism and ionic saturation have a pivotal role in the biodistribution of bone tracers. This phenomenon ranks in a complex scenario that includes carcinogenesis and cancer environment aspects. We also report two cases in our Institution in which atypical uptake in cancer tissues was observed.

目的:锝-99m(99mTc)-二膦酸盐是骨闪烁成像最常用的放射性药物。尽管骨组织中的摄取已被广泛探究,但在骨闪烁成像过程中,软组织恶性肿瘤也会出现不典型的摄取。血管化和内皮通透性的增加是示踪剂生物分布的主要因素,但也发现了其他原因,如创伤、坏死、转移瘤中的钙化、组织的 pH 值以及离子浓度的类型:本文旨在总结癌症组织中非典型软组织摄取的最新进展。研究是在 PubMed 上进行的。文献分析表明,钙代谢和离子饱和度在骨示踪剂的生物分布中起着关键作用。这一现象涉及致癌和癌症环境等复杂因素。我们机构还报告了两例在癌症组织中观察到非典型吸收的病例。

Purpose: Gene expression (GE) analysis of a radio-sensitive gene set (FDXR, DDB2, WNT3, POU2AF1) has been introduced in the last decade as an early and high-throughput prediction tool of later developing acute hematologic radiation syndrome (H-ARS) severity. The use of special tubes for RNA extraction from peripheral whole blood (PAXgene) represent an established standard in GE studies, although uncommonly used in clinics and not immediately available in the quantities needed in radiological/nuclear (R/N) incidents. On the other hand, EDTA blood tubes are widely utilized in clinical practice.

Material and methods: Using blood samples from eleven healthy donors, we investigated GE changes associated with delayed processing of EDTA tubes up to 4 h at room temperature (RT) after venipuncture (simulating delays caused by daily clinical routine), followed by a subsequent transport time of 24 h at RT, 4 °C, and -20 °C. Differential gene expression (DGE) of the target genes was further examined after X-irradiation with 0 Gy and 4 Gy under optimal transport conditions.

Results: No significant changes in DGE were observed when storing EDTA whole blood samples up to 4 h at RT and subsequently kept at 4 °C for 24 h which is in line with expected DGE. However, other storage conditions, such as -20 °C or RT, decreased RNA quality and/or (significantly) caused changes in DGE exceeding the known methodological variance of the qRT-PCR.

Conclusion: Our data indicate that the use of EDTA whole blood tubes for GE-based H-ARS severity prediction is comparable to the quality of PAXgene tubes, when processed ≤ 4 h after venipuncture and the sample is transported within 24 hours at 4 °C.

目的:在过去的十年中,放射敏感基因集(FDXR、DDB2、WNT3、POU2AF1)的基因表达(GE)分析已被引入,作为后期发展为急性血液学放射综合征(H-ARS)严重程度的早期高通量预测工具。从外周全血(PAXgene)中提取RNA的特殊管的使用代表了通用电气研究中的既定标准,尽管在临床中很少使用,并且在放射性/核(R/N)事件中无法立即获得所需的数量。另一方面,EDTA血管在临床实践中得到了广泛的应用。材料和方法:使用来自11名健康献血者的血液样本,我们研究了与EDTA试管延迟处理长达4小时相关的GE变化 静脉穿刺后在室温(RT)下放置h(模拟日常临床常规造成的延迟),随后运输时间为24 室温下的h,4 °C和-20 °C。靶基因的差异基因表达(DGE)在用0 Gy和4 Gy。结果:当EDTA全血样品储存至4小时时,DGE没有观察到显著变化 在RT下为h,随后保持在4 °C 24 h,这与预期的DGE一致。但是,其他储存条件,如-20 °C或RT,降低RNA质量和/或(显著)导致DGE变化超过qRT-PCR的已知方法学方差。结论:我们的数据表明,使用EDTA全血管进行基于GE的H-ARS严重程度预测与PAX基因管的质量相当,当处理≤4 静脉穿刺后h,样品在24小时内运输 4小时 °C。

Purpose: This manuscript aimed for the generation of γ-irradiation derived mutants of potato genotype PAU/RR-1501 possessing desirable processing traits.

Materials and methods: Nodal cuttings from virus-free explants were established on basal MS medium and irradiated with different doses (0, 5, 10 and 20 Gy) of γ-irradiation. The 5 and 10 Gy treated plantlets were multiplied and used for micro-tuber induction. Harvested micro-tubers were planted in pots for the selection and evaluation of mutants in M1V2 generation.

Results: Four weeks post-treatment, plantlets (5 Gy) showed enhanced growth as compared to the control while 20 Gy treatment exhibited completely ceased shoot growth. The highest number and weight of mini-tubers per plant was recorded for 10 Gy followed by 5 Gy treatment as compared to control. The γ-irradiation treatments caused changes in the skin color and shape of M1V2 tubers.

Conclusion: Under the 5 Gy treatment 49.9% of clones produced exhibited cream and 8.53% brown skin color. Nine putative mutants were identified in genotype PAU/RR-1501 exhibiting promising processing traits.

目的:本手稿旨在生成具有理想加工性状的马铃薯基因型 PAU/RR-1501 的γ-辐照衍生突变体:在基础 MS 培养基上建立无病毒外植体的节间插条,并用不同剂量(0、5、10 和 20 Gy)的 γ 辐射照射。经 5 和 10 Gy 处理的小植株被繁殖并用于微管诱导。收获的微管种植在花盆中,用于 M1V2 代突变体的筛选和评估:处理后四周,与对照组相比,5 Gy 处理的小苗生长速度加快,而 20 Gy 处理的小苗则完全停止了生长。与对照相比,10 Gy 处理的每株小管数量和重量最高,其次是 5 Gy 处理。γ-辐照处理导致 M1V2 块茎的表皮颜色和形状发生变化:结论:在 5 Gy 处理下,49.9% 的克隆表现出奶油色,8.53% 的克隆表现出棕色。在基因型 PAU/RR-1501 中发现了 9 个推定突变体,这些突变体具有良好的加工性状。
