Radioresistant cells have been shown to correlate with poor outcome after radiotherapy. Here, we found that human telomerase reverse transcriptase promoter (hTERTp) had lower activity in laryngeal squamous carcinomas cells than in radioresistant variant cells. Combining radiotherapy with plasmid phTERTp-HRP, in which expression of enzyme horseradish peroxidase (HRP) controlled by hTERTp, resulted in increased apoptosis and necrosis of tumor cells after prodrug indole-3-acetic acid (IAA; converted by HRP into a cytotoxin) incubation. Volume and wet weight of xenograft tumor were reduced more in the combination groups. These data suggest that hTERTp has potential use in targeted cancer gene therapy, especially for radioresistant tumors. Combining radiotherapy with hTERTp-HRP/IAA may overcome radioresistance in laryngeal squamous carcinomas cells and amplify the killing effect in targeted cancer cells. (C) 2009 Elsevier Ireland Ltd.

An Investigation of the Hysteretic Behavior of a Buckling-Restrained Brace Subsystem Frame with Out-of-Plane Eccentricity

Yongsheng Cao, Yun Zhou, Genquan Zhong, Xuesong Deng, Jiro Takagi

Summary: This paper examines the differences in hysteretic behavior of buckling-restrained brace subsystem frames (BRBFs) with concentric and out-of-plane eccentric configurations. The study found that the out-of-plane eccentric BRBFs have different mechanical properties and deformation patterns compared to the concentric BRBFs under in-plane quasi-static loads.

Sliding gusset connections for improved seismic performance of BRB-RC frame: Damage-control design and subassemblage tests

Junxian Zhao, Jiaguang Zhang, Jiayu Song, Yun Zhou, Jiulin Bai, Haichao Yu

Summary: In this study, two innovative sliding gusset connections are proposed to mitigate the negative frame-to-gusset interaction in buckling-restrained brace (BRB) reinforced concrete frames (RCFs). A damage-control design procedure is presented to prevent undesirable failure of the BRB-RCF joint. Cyclic tests of five BRB-RCF subassemblages were conducted to evaluate the sliding mechanism and the effectiveness of the design procedure.

Soil metagenome and metabolome of peanut intercropped with sorghum reveal a prominent role of carbohydrate metabolism in salt-stress response

Xiaolong Shi, Yufei Zhou, Xinhua Zhao, Pei Guo, Jingyao Ren, He Zhang, Qiqi Dong, Zheng Zhang, Haiqiu Yu, Shubo Wan

Summary: Soil metabolomics and metagenome sequencing were used to investigate the salt-stress response in peanuts intercropped with sorghum. The study found that carbohydrate metabolism was the most differentially expressed pathway, with certain metabolites more abundant in intercropped peanuts under salt stress. In addition, there was a higher abundance of specific microbial taxa in intercropped peanuts under salt stress. These findings suggest that intercropping can indirectly influence beneficial microbial communities and potentially enhance peanut's salt tolerance.

Photonic spin Hall effect with high coupling efficiency in the combined structure of periodic dielectric waveguides and photonic crystal waveguide

Yi-Chen Zhang, Li-Ming Zhao, Yun-Song Zhou

Summary: In this paper, the photonic spin Hall effect (PSHE) in the combined structure of periodic dielectric waveguides (PDWs) and photonic crystal waveguide (PCW) is discussed. The arbitrary manipulation of PSHE for the PDW guided mode in the structure is successfully achieved by controlling the polarization of the dipole source. The advantage of PDW is its ability to be designed to different shapes without geometric constraints, while maintaining a relatively high transmission rate. By further changing the structure, including the adjustment of the intersection angle between PDW and PCW, and the alteration of the straight PDW to the bending or bifurcated shapes, it is found that the output of highly unidirectional PSHE is mainly determined by the intersection angle between PDW and PCW and almost independent of the detailed shape of PDW.

Effects of Exogenous Auxin on Mesocotyl Elongation of Sorghum

Chang Liu, Ziqing Yao, Bing Jiang, Wenbo Yu, Yu Wang, Wenhui Dong, Yutong Li, Xiaolong Shi, Chunjuan Liu, Yufei Zhou

Summary: This study aimed to investigate the physiological mechanism of exogenous auxin (IAA) promoting mesocotyl elongation in sorghum. The results showed that exogenous IAA significantly increased cell length and promoted mesocotyl elongation in the short mesocotyl inbred line MS24B, while the application of the IAA inhibitor NPA resulted in a significant decrease in mesocotyl length. In the long mesocotyl inbred line Z210, exogenous IAA had a slight effect on mesocotyl elongation, while NPA treatment considerably reduced mesocotyl length. Overall, exogenous IAA activated energy metabolism, leading to plasma membrane acidification and mesocotyl elongation.

Raising Dogs that Bite: How Pastoralists and Breeders Care for Tibetan Mastiffs

Yufei Zhou

Summary: This paper discusses the commodification of Tibetan Mastiffs and the care relationship between humans and dogs. Tibetan pastoralists and dogs have a reciprocal yet distanced care relationship, while breeders of Tibetan Mastiffs focus on their ferociousness, resulting in a more dedicated but unilateral and dangerous care approach. The unintended consequence of breeders' care is that they raise dogs that sometimes bite, due to the transformation of dogs' guarding abilities from ethical virtue to commercial value.

Elevated 2-oxoglutarate antagonizes DNA damage responses in cholangiocarcinoma chemotherapy through regulating aspartate beta-hydroxylase

Katsuya Nagaoka, Xuewei Bai, Dan Liu, Kevin Cao, Joud Mulla, Chengcheng Ji, Hongze Chen, Muhammad Azhar Nisar, Amalia Bay, William Mueller, Grace Hildebrand, Jin-Song Gao, Shaolei Lu, Hiroko Setoyama, Yasuhito Tanaka, Jack R. Wands, Chiung-Kuei Huang

Summary: This study found that serum 2-OG levels in cholangiocarcinoma patients are associated with the effectiveness of chemotherapy. Patients with progressive disease showed significantly higher levels of serum 2-OG compared to stable disease and partial response patients. The study also revealed that overexpression of ASPH mimics the effects of 2-OG, and knockdown of ASPH improves chemotherapy. Targeting ASPH enhances the effects of chemotherapy by modulating ATM and ATR, two key regulators of DDRs.
