IntroductionAfter gastric cancer surgery, solitary bone metastasis is very rare, and repeated pelvic metastasis has not been reported. This article reports a case of recurrent pelvic metastasis after early gastric cancer surgery, in which the patient achieved long-term survival through multiple aggr...

Passive millimeter-wave imaging has emerged as a useful tool in many remote sensing applications, including resource remote sensing, material classification, and target detection. This paper presents a method to classify specular objects based on their material composition from passive millimeter-wa...

Fatty acid metabolism is responsible not only for oilseed metabolism but also for plant responses to abiotic stresses. In this study, three novel genes related to fatty acid degradation designated GhACX, Gh4CL, and GhMFP, respectively, were isolated from Gossypium hirsutum acc. TM-1. The phylogeneti...

Development of colorectal cancer has been considered as a result of imbalance of pro- and anti-inflammatory intestinal microenvironment accompanied by macrophage recruitment. Despite macrophages are implicated in remodeling tumor microenvironment, the mechanism of macrophage recruitment is not fully...

ABSTRACT Plants naturally host a variety of microbial communities, which significantly affect their health and productivity. Cinnamomum migao is a rare and endangered medicinal plant endemic to Southwest China. However, the related research on endophytic fungi of C. migao has been neglected, especia...

The key activity to build semantic web is to build ontologies. But today, the theory and methodology of ontology construction is still far from ready. This paper proposed a theoretical framework for massive knowledge management – the knowledge domain framework (KDF), and introduces an integrated dev...

Pectin is a major constituent of the plant cell wall. Pectate lyase (PEL, EC 4.2.2.2) uses anti-β-elimination chemistry to cleave the α-1,4 glycosidic linkage in the homogalacturonan region of pectin. However, limited information is available on the comprehensive and evolutionary analysis of PELs in...

Rock glaciers are debris landforms formed by long-term creep of ice-rich permafrost. Their kinematics provide critical insights for climate change and permafrost studies, mountain hydrology, and hazard assessment. Previous studies have measured rock glacier velocities using field-based terrestrial g...

脑小血管病（cerebral small vessel disease，CSVD）是一组病因复杂的神经系统疾病，主要表现为缺血或出血性卒中，以及认知功能障碍、精神情感异常和步态障碍等，神经影像学特征包括近期皮质下梗死、血管周围间隙扩大、脑微出血、颅内出血、脑萎缩、血管源性腔隙灶和脑白质病变。单基因CSVD是其中一类罕见的亚型，占全部病因的1%～5%，目前已报道的CSVD致病基因达数十个。除CSVD共同的临床和影像学表现外，单基因CSVD常有特异性的表现，尤其是神经系统外症状，对诊断具有较强的提示作用。鉴于CSVD相关基因的检测分析耗时且具有挑战性，全面认识单基因CSVD的神经系统症状和神经系...

Phosphorus (P) is an essential macronutrient for plant growth, but its availability in soil is often insufficient to achieve optimum crop yield. The As-hyperaccumulator Pteris vittata thrives under low-P condition, with the underlying mechanisms remaining unclear. To understand the P-scavenging trai...

ObjectiveWhile growing evidence supports the Geriatric Nutritional Risk Index (GNRI) as a prognostic indicator for various cancers, its predictive value in pancreatic cancer remains unclear. This meta-analysis systematically evaluates GNRI’s ability to predict postoperative complications and long-te...

In this study the transfer characteristics of mercury (Hg) from a wide range of Chinese soils to corn grain (cultivar Zhengdan 958) were investigated. Prediction models were developed for determining the Hg bioconcentration factor (BCF) of Zhengdan 958 from soil, including the soil properties, such...

Extraintestinal pathogenic Escherichia coli (ExPEC) is an important zoonotic pathogen. Recently, ExPEC has been reported to be an emerging problem in pig farming. However, the mechanism of pathogenicity of porcine ExPEC remains to be revealed. In this study, we constructed a transposon (Tn) mutagene...
