The first macrocycle-based high-nuclearity nanocluster [Ag-20((SBu)-Bu-t)(10)(CF3COO)(2)](8+) in complex 1, with a sandwich-like structure constructed by bilevel inversion Ag5S5 pentagrams and an inter-layer Ag-10 ring, has been obtained. Structure analysis indicates that Cl- acts as an anion template to direct the formation of 1. In addition, the photoluminescent property of complex 1 is also investigated.

The effect of different biocrusts on soil hydraulic properties in the Tengger Desert, China

Wei Shi, Yan-xia Pan, Ya-feng Zhang, Rui Hu, Xin-ping Wang

Summary: Water redistribution has a profound impact on the function of dryland ecosystems. Biological soil crusts (BSCs or biocrusts), which cover a large portion of arid land soil surface, have conflicting effects on water redistribution at a regional scale. This study clarified the effects of different biocrusts on soil hydraulic properties in the Tengger Desert. The results showed that biocrusts significantly altered soil hydraulic properties, including water holding capacity, soil hydrophobicity, water sorptivity, and unsaturated hydraulic conductivity. Understanding the role of biocrusts in hydraulic properties can help improve our understanding of soil water distribution, movement, and retention in the area.

Summary: The purpose of this study was to evaluate the biological effects of cancer stem cells (CSCs) irradiated by charged particle, including proliferation, invasion, migration, and changes in the molecular level. The results showed that CSCs have obvious radio-resistance compared with non-CSCs, and charged particle irradiation or in combination with drugs could overcome this resistance, specifically manifested in inhibiting CSCs' proliferation, invasion, migration, and causing more and harder to repair DNA double-stranded breaks (DSB) of CSCs.

K2Ni(SeO3)2: A Perfect S=1 Triangular-Lattice Antiferromagnet with Strong Geometric Frustration and Easy-Plane Anisotropy

Zhengrong Li, Zhongwen Ouyang, Jiaojiao Cao, Xiaochen Liu, Tongtong Xiao, Lei Wang, Youyuan Liang, Zhaoming Tian, Zhenxing Wang, Zhengcai Xia

Summary: A new perfect triangular lattice antiferromagnet K2Ni(SeO3)(2) has been synthesized, in which both in-plane and inter-plane geometric frustration is present. The compound shows antiferromagnetic order at T(N) ≈ 7 K. High-field magnetization and electron spin resonance indicate the presence of easy-plane anisotropy. Density functional theory calculations confirm the excellent two-dimensionality of the compound. Thus, K2Ni(SeO3)(2) is a perfect triangular-lattice antiferromagnet with strong frustration and easy-plane anisotropy.

Association of soft drinks and 100% fruit juice consumption with risk of cancer: a systematic review and dose-response meta-analysis of prospective cohort studies

Bei Pan, Honghao Lai, Ning Ma, Dan Li, Xiyuan Deng, Xiaoman Wang, Qian Zhang, Qiuyu Yang, Qi Wang, Hongfei Zhu, Mengting Li, Xiao Cao, Jinhui Tian, Long Ge, Kehu Yang

Summary: Through a systematic review and meta-analysis of 37 cohort studies, it was found that an increased consumption of sugar-sweetened beverages (SSBs) per 250 mL/day was associated with a higher risk of breast, colorectal, biliary tract, and prostate cancer. Increased consumption of artificially sweetened beverages (ASBs) per 250 mL/day was associated with a higher risk of leukemia. Increased consumption of 100% fruit juice per 250 mL/day was associated with a higher risk of overall cancer, melanoma, squamous cell carcinoma, and thyroid cancer. There were linear dose-response associations between SSBs consumption and breast and kidney cancer, and between ASBs and fruit juices consumption and pancreatic cancer.

A Meta-analysis of the Clinical Efficacy of the Head-of-Bed Elevation for Patients With Acquired Brain Injury

Ying Che, Tingting Lu, Tianming Wang, Hairong Zhao, Xulin Song, Qing Zhan, Chengzu Zhang, Haibang Pan, Kehu Yang, Bo Wang

Summary: This study evaluated the effects of head-of-bed elevation on patients with acquired brain injury (ABI). The results showed that elevating the head of the bed by 30 degrees can significantly reduce intracranial pressure (ICP), but did not have statistical differences on cerebral perfusion pressure (CPP) and disability at 90 days. Therefore, head-of-bed elevation of 30 degrees may be an effective noninvasive nursing practice for the prognosis and rehabilitation of ABI patients.

Genome-Wide Identification and Evolution Analysis of the CYP76 Subfamily in Rice (Oryza sativa)

Mingao Zhou, Yifei Jiang, Xuhui Liu, Weilong Kong, Chenhao Zhang, Jian Yang, Simin Ke, Yangsheng Li

Summary: The CYP76 subfamily, which belongs to the CYP superfamily, is crucial for phytohormone biosynthesis and response to environmental stresses in plants. Genome-wide analysis of the CYP76 subfamily in seven AA genome species revealed three groups, with Group 1 having the largest number of members. Analysis of cis-acting elements showed a high number of elements related to jasmonic acid and light response. Gene duplication analysis indicated expansion mainly through SD/WGD and tandem forms, with strong purifying selection during evolution. Expression pattern analysis showed that OsCYP76s exhibit restricted expression patterns in leaves and roots. qRT-PCR analysis of CYP76s under abiotic stresses revealed specific response patterns and functional divergence between japonica and indica rice. These findings provide valuable insights into the functional diversity and evolution of the CYP76 subfamily and have implications for improving stress tolerance and agronomic traits in rice.

Unlocking the catalytic potential of gold(II) complexes: a comprehensive reassessment

Juan Carlos Perez-Sanchez, Raquel P. Herrera, M. Concepcion Gimeno

Summary: Gold(II) complexes have been less utilized in catalysis compared to their gold(I) and gold(III) counterparts. However, gold(II) complexes offer potential in homo-coupling and cross-coupling reactions, as they are more easily accessible through simplified oxidation and reduction processes. Gold(II) exhibits characteristics of both soft acid gold(I) and hard acid gold(III). This review explores the unique reactivity and potential applications of gold(II) species, highlighting their significance in catalytic transformations.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
