Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT A facile coprecipitation‐pyrolysis strategy was employed to fabricate Cu/Co nanoparticles (NPs) embedded in nitrogen‐doped carbon matrices (Cu/Co@N‐C) through the carbonization of CuCo‐MOF precursors. Moreover, monometallic counterparts of Cu@N‐C and Co@N‐C were also prepared via carbonization of bimetallic CuZn‐MOF and CoZn‐MOF, respectively.

食管黏膜脱落细胞DNA倍体联合血清标志物检测在食管癌诊断中的价值
Zhongguo shiyan zhenduanxue, 2016 目的探讨血清肿瘤标志物神经元特异性烯醇化酶（NSE）、癌胚抗原（CEA）联合食管黏膜脱落细胞DNA倍体在食管癌诊断中的应用价值。方法选取我院收治的经胃镜诊断为食管病变患者128例,其中64为食管癌患者,64例为食管良性病变患者,使用罗氏电化学发光免疫系统检测其血清NSE、CEA水平,采用ICM检测DNA倍体水平,分析其特异性及敏感性。结果 64例食管癌患者中有45例DNA倍体为阳性,64例食管良性病变患者中,3例DNA倍体异常,食管癌组患者的NSE、CEA水平均明显高于良性病变组,组间比较有明显差异 ...

Informal supply chains of wild meat from rural Amazonia and food security in an urban center
Conservation Biology, Volume 40, Issue 4, August 2026.Abstract Iquitos, the most populated city in the Peruvian Amazon, is a hub in the regional supply chain of wild meat and supplies urban consumers. Studies on wild meat consumption have focused primarily on markets, limiting the scope of species considered to those that are economically valuable and potential inferences from those data.

Reconstructing Old Chinese *‐ts Using Han‐Time Material
Transactions of the Philological Society, Volume 124, Issue 2, Page 487-512, July 2026.Abstract Baxter & Sagart (2014b) reconstruct *‐Vt‐s on the basis of Middle Chinese reflexes in ‐jH (from some OC *‐s) coupled with either etymological or graphic connections to words in Middle Chinese ‐t. This approach, while perfectly sound, can suffer from lack of etymological or graphic data, leading to missed reconstructions. Since Old Chinese *‐ts
