Up to now, numerous emerging methods of cancer treatment including chemodynamic therapy, photothermal therapy, photodynamic therapy, sonodynamic therapy, immunotherapy and chemotherapy have rapidly entered a new stage of development. However, the single treatment mode is often constrained by the complex tumor microenvironment. Recently, the nanomaterials and nanomedicine have emerged as promising avenues to overcome the limitation in cancer theranostics. Especially, metal-organic frameworks (MOFs) have gained considerable interests in cancer therapy because of their customizable morphologies, easy functionalization, large specific surface area, and good biocompatibility. Among these MOFs, iron-based MOFs (Fe-MOFs) are particularly promising for cancer treatment due to their properties as nano-photosensitizers, peroxidase-like activity, bioimaging contrast capabilities, and *** their structural regularity and synthetic tunability, Fe-MOFs can be engineered to incorporate organic molecules or other inorganic nanoparticles, thereby creating multifunctional nanoplatforms for single or combined theranostic modes. Herein, the minireview focuses on the recent advancements of the Fe-MOFs-based nanoplatforms for self-enhanced imaging and treatment at tumor sites. Furthermore,the clinical research development of Fe-MOFs-based nanoplatforms is discussed, addressing key challenges and innovations for the future. Our review aims to provide novice researchers with a foundational understanding of advanced cancer theranostic modes and promote their clinical applications through the modification of Fe-MOFs.

Beyond amplitude: Phase integration in bird vocalization recognition with MHAResNet

Avian Research 2025年第01期 119-128页

作者： Jiangjian Xie Zhulin Hao Chunhe Hu Changchun Zhang Junguo Zhang School of Technology Beijing Forestry University State Key Laboratory of Efficient Production of Forest Resources Beijing Forestry University Key Laboratory of National forestry and Grassland Administration on forestry Equipment and Automation Research Center for Biodiversity Intelligent Monitoring Beijing Forestry University

Bird vocalizations are pivotal for ecological monitoring, providing insights into biodiversity and ecosystem health. Traditional recognition methods often neglect phase information, resulting in incomplete feature representation. In this paper, we introduce a novel approach to bird vocalization recognition(BVR) that integrates both amplitude and phase information, leading to enhanced species identification. We propose MHARes Net, a deep learning(DL) model that employs residual blocks and a multi-head attention mechanism to capture salient features from logarithmic power(POW), Instantaneous Frequency(IF), and Group Delay(GD) extracted from bird vocalizations. Experiments on three bird vocalization datasets demonstrate our method's superior performance, achieving accuracy rates of 94%, 98.9%, and 87.1. respectively. These results indicate that our approach provides a more effective representation of bird vocalizations, outperforming existing methods. This integration of phase information in BVR is innovative and significantly advances the field of automatic bird monitoring technology, offering valuable tools for ecological research and conservation efforts.

PrDA1.1.and its interacting proteins PrTCP1.PrTCP9 in flare tree peony affect yield by regulating seed weight and number

引用

Journal of Integrative Agriculture 2025年第02期24卷 610-622页

作者： Chunyan He Fangyun Cheng State Key Laboratory of Efficient Production of Forest Resources Beijing Forestry University National Engineering Research Center for Floriculture Beijing Forestry University Peony International Institute Beijing Forestry University School of Landscape Architecture Beijing Forestry University

Tree peony is an emerging woody oilseed crop that has the potential to help meet the growing demand for edible oil and biofuel, and breeding high-yield varieties is the key to increasing production. The DA1.gene regulates seed weight and number and effectively improves crop yield, although its function in tree peonies has not yet been reported. In this study, three PrDA1.genes were first identified in the whole genome of ‘Jing Hong' flare tree peony(Paeonia rockii). PrDA1.1.is homologous to AtDA1.and contains three types of conserved structural domains: UIM(ubiquitin-interacting motif), LIM(Lin1., Isl-1. and Mec-3), and DA-like. PrDA1.1.was strongly expressed during both the early and late stages of seed development, and its constitutive expression in Arabidopsis reduced seed number but increased seed weight, which ultimately led to a reduction in yield. PrDA1.1.was found to interact with PrTCP1.PrTCP9 in yeast and plants, and the constitutive expression of PrTCP1.PrTCP9 in Arabidopsis increased seed weight and number, which resulted in higher yield. Since this study showed that PrDA1.1.and PrTCP1.PrTCP9 regulate seed weight and number to affect yield, these new genetic resources will help to improve the seed yield of tree peonies.

Increasing temperatures and severe droughts threaten forest vitality globally. Prediction of forest response to climate change requires knowledge of the spatiotemporal patterns of monthly or seasonal climatic impacts on the growth of tree species, likely driven by local climatic aridity, climate trends, edaphic conditions, and the climatic adaption of tree species. The ability of tree species to cope with changing climate and the effects of environmental variables on growth trends and growth-climate relationships across diverse bioclimatic regions are still poorly understood for many species. This study investigated radial growth trends, interannual growth variability, and growth-climate sensitivity of two dominant tree species, Pinus tabulaeformis(PT) and Pinus sylvestris var. mongolica(PS), across a broad climatic gradient with a variety of soil properties in temperate Northern China. Using a network of 83 tree ring chronologies(54 for PT and 29 for PS) from 1.71.to 201., we documented that both species maintained constant growth trends at wet sites, while both displayed rapid declines at dry sites. We reported the species-specific drivers of spatial heterogeneity in growth trends, interannual growth variability, and growth-climate relationships. Calculated climatic variables and soil properties were identified as the most critical factors affecting the growth trends and growth-climate relationships. However, climatic variables play more essential roles than soil properties in determining the spatial heterogeneity of the growth-climate *** clay content and higher soil nutrient regimes can exacerbate the moisture-related susceptibility of tree growth. Our findings highlight that soil properties emerged as important modulating factors to predict the drought vulnerability of forests in addition to climatic variables. Considering the continued climate warmingdrying trend in the future, both pines will face a more severe growth decline and increase in dr
