Policy, Waste, and Power: Textile Dumping in Chile's Atacama Desert
Latin American Policy, Volume 17, Issue 2, June 2026.ABSTRACT Globally, 87% of textile fibers end up incinerated or in landfills, with Chile bearing the brunt of this crisis. Every year, 39,000 tons of discarded clothing are illegally dumped in the Atacama Desert, turning it into a sacrifice zone for the Global North's waste economy.

Zhongguo shiyan zhenduanxue, 2016 目的从单克隆抗体水平研究同种异体肾移植受者多反应性抗体与HLA抗体的相关性,探讨多反应性抗体是否为HLA抗体尤其是非供体特异性抗体产生的原因之一。方法从肾移植患者外周血细胞及手术切除的移植肾组织中分离出B淋巴细胞,并于体外永生化培养获得单克隆B细胞,分别检测B细胞分泌的抗体对HLA抗原及凋亡细胞的反应性。结果共获得107个B细胞克隆,检测发现每个B细胞克隆在体外培养过程中均分泌抗体。其中有4个单克隆B细胞分泌的抗体可以与多种HLA抗原发生反应,而这些HLA抗原之间并非都有共用的抗原决定簇。进一步研究发现,

New Phytologist, Volume 250, Issue 5, Page 3230-3246, June 2026.Summary Carotenoids and apocarotenoids are widespread specialized metabolites, yet animals, including sponges, lack the ability to synthesize carotenoids de novo and must obtain them from dietary or microbial sources. The roles of carotenoid cleavage dioxygenases (CCDs) in marine animals remain largely unexplored. A CCD from the marine sponge Suberites

12kV固体柜环氧浇注模块外表面无金属化层时的电场分布特征研究
Gaoya dianqi, 2016 固体绝缘技术在中压特别是12 k V开关设备当中已经得到广泛的认可与应用。为实现固体柜产品小型化、提高耐候性、安全性等目的,在固体柜绝缘表面进行金属化处理成为当前新的研究热点。但目前固体柜产品中很大一部分环氧浇注外表面未做金属化处理,文中对现有12 k V固体柜产品环氧浇注模块外表面无金属化处理时的电场分布特征进行了仿真研究。仿真结果表明,现有固体柜产品环氧浇注模块外表面无金属化层时,固体柜能够满足电场绝缘考核要求,但环氧浇注模块内部真空灭弧室结构及环氧模块与柜体外壳间隙距离对固体柜的电场分布影响显著。

Effects of Treponema pallidum on THP-1 derived macrophage polarization [PDF]
, 2015 梅毒螺旋体（Treponemapallidum）是性传播疾病梅毒的致病菌，尽管有关T.pallidum的研究已经开展近一个多世纪，对其生物学及病原学特性有了一定的了解，然而对于T.pallidum致病机制的认识还处于起步阶段。巨噬细胞作为机体防御外来病原体的第一道防线，在对T.pallidum的识别、吞噬、抗原提呈、杀伤等方面均发挥着重要作用。随着对巨噬细胞研究不断深入，有学者将巨噬细胞分为两种不同的极化类型，即促进炎症发展的M1型巨噬细胞和在抑制炎症反应及组织修复等方面发挥作用的M2型巨噬细胞 ...

New Phytologist, Volume 250, Issue 5, Page 3283-3298, June 2026.Summary Plant resistance influences the host range of pathogens; however, the mechanism driving this influence remains poorly understood. Brassicaceae species are not natural hosts of potexviruses, for reasons that have not yet been determined. This study investigated the molecular basis of nonhost resistance (NHR) to potexviruses in the Brassicaceae ...

The establishment of arsenite-transformed cells (TLECs) and the study on methylation of non-CpG island promoter repressing NQO1 expression in TLECs [PDF]
, 2016 摘 要 砷及其衍生物广泛分布自然环境并对人类健康构成危害。虽然流行病学研究已经证实长期的砷暴露能诱发多种癌症，但对砷致癌的确切机制目前远未被阐明，需要进一步深入地探索。砷诱导肿瘤形成是一个长期和复杂的过程，相关研究工作首先需要一个合适的细胞模型。为此，我们以低浓度亚砷酸钠长时间处理正常的大鼠肺上皮细胞系（LECs）诱导其转化，再通过一系列的指标实验验证，成功地建立砷转化细胞模型TLECs（Arsenite-transformedLECs），从而为下一步的研究奠定基础 ...

ABCA12 Frameshift Deletion in Domestic Cats With Ichthyosis Fetalis
Veterinary Dermatology, Volume 37, Issue 3, Page 365-374, June 2026.ABSTRACT Background Ichthyosis fetalis (IF), also known as harlequin ichthyosis, is a rare and often fatal autosomal recessive congenital skin disorder. It is characterized by thickened, hard skin plaques and deep skin fissures that limit mobility and cause malformations of the eyes, lips and ears.
