Zhejiang Daxue xuebao. Lixue ban, 2011 主要依据准噶尔盆地东北缘青格里底山前冲断带二维地震剖面的精细地质解释，并结合临近阿尔泰造山带燕山期花岗岩的同位素定年，认为准噶尔盆地东北缘在中侏罗世存在逆冲构造变形.该构造变形发生于中侏罗统西山窑组(J2x)沉积期，形成了走向北西、倾向北东的逆断层及断层传播褶皱，表明其时准噶尔盆地东北缘曾受到来自于北东方向的挤压应力作用，其力源可能和西伯利亚板块与蒙古-华北板块的碰撞、拼贴事件有关，是蒙古-鄂霍次克洋闭合的陆内反映.这对于促进北疆地区构造变形与盆山关系的研究具有重要意义.

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Human‐driven landscape change, particularly urbanization, is reshaping pollinator communities, yet the functional traits that mediate species persistence remain poorly understood. Dietary specialization is commonly used to predict species vulnerability.

Zhongguo shiyan zhenduanxue, 2020 去分化脂肪肉瘤(DDLPS)在WHO骨和软组织肿瘤分类标准中的定义是不典型性脂肪瘤性肿瘤/高分化脂肪肉瘤(ALT/WDL)去分化为不同分化程度的肉瘤,其去分化成分多为高级别肉瘤,如多形性未分化肉瘤、纤维肉瘤和粘液性原纤维肉瘤等,也有伴低级别肉瘤成分[1]。其中血管肉瘤成分极其少见,国内外文献中精索DDPLS中存在血管肉瘤成分的病例仅1例报道[2]。此外 ...

多参数磁共振成像联合表观弥散系数直方图分析预测膀胱癌的病理分化
Zhongshan Daxue xuebao. Yixue kexue ban, 2023 目的探讨多参数磁共振成像联合表观弥散系数（ADC）直方图分析应用于膀胱癌合并其他病理分化类型的预测价值。方法回顾性收集并分析2015年3月至2023年3月就诊于中山大学附属第一医院并经手术病理证实为膀胱尿路上皮癌患者的临床及影像学资料。根据术后病理结果，将患者分为有合并其他病理分化（如鳞状分化、腺样分化等）组及无其他病理分化组。运用倾向性评分匹配的方法，将无分化组患者按年龄及性别与有分化组患者进行两组间1∶1最邻近匹配，两组均入组49例。使用ITK ...

Regulation of PI3K and MAPK inhibitors on the activity of FOXO1 and their effect on biological behavior of GIST-T1 gastric stromal tumor cell lines [PDF]
, 2015 胃肠道间质瘤（gastrointestinalstromaltumors,GISTs）是消化道最常见的间叶组织肿瘤。目前普遍认为GISTs起源于向cajal细胞分化的原始间叶细胞或幼稚干细胞，具有多向分化特征，可以向平滑肌、神经分化或不定向分化，是一种具有恶性潜能的胃肠道肿瘤，但其确切起源尚不明确。其发病率为1～2/10万人口,似乎正逐渐增加。近年来有研究表明，PI3K（磷脂酰肌醇-3-激酶）和MAPK（丝裂原活化蛋白激酶）信号通路活性在胃肠道间质瘤显著增高 ...

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Most terrestrial plant species form symbioses with arbuscular mycorrhizal fungi (AMF). However, the below‐ground carbon (C) allocation of plants and the nutritional and growth benefits provided by AMF within this symbiosis vary greatly across species and environments ...

Brd4 participates MyoD auto-regulation via its core enhancer element [PDF]
, 2016 肌肉分化决定因子MyoD是调节成肌细胞分化方向的关键转录因子。在成肌细胞形成早期MyoD开始表达出现，一直持续表达到肌肉分化完成，成肌细胞的命运也受到MyoD表达变化的影响。当MyoD最早开始表达时，表达量极低，但其自激活作用会迅速形成正反馈推升其表达，进而激活肌肉功能基因，使成肌细胞分化为肌细胞；而成肌细胞中MyoD表达抑制则会导致肌肉祖细胞生产，由于被MyoD抑制的细胞周期相关基因恢复表达，成肌细胞经过不对称分裂具有再生能力的卫星细胞便会产生，这个步骤对肌肉组织受损应急来说至关重要 ...

STREETS AS STAGES: Traffic Enforcement and the Competition for Cultural Growth in China
International Journal of Urban and Regional Research, EarlyView.ABSTRACT In keeping with China’s desire to build soft power to parallel its economic growth, the policing of city streets has moved to the forefront as a mechanism for moral regulation and improving urban prestige. Under pressure to civilize their citizenry, many Chinese cities have become entrepreneurial cities within a type of cultural growth ...
