血清miR-21对结直肠癌肝转移预测价值的评价

Zhongguo shiyan zhenduanxue, 2018
目的探讨血清miR-21对结直肠癌肝转移预测的诊断价值,以期为临床的结直肠癌肝转移的预测提供一种潜在的辅助诊断方法。方法检测146例晚期结直肠癌无肝转移患者和124例晚期结直肠癌伴肝转移患者血清中CEA的含量和miR-21的相对表达值,评价其单独检测和联合检测对于结直肠癌肝转移的预测的诊断价值。结果与结直肠癌无肝转移组相比,结直肠癌伴随肝转移组的CEA和miR-21均显著升高 ...

Acoustically Assisted Heterojunction Hydrogel Promotes Angiogenesis and Tissue Regeneration by Modulating the Inflammatory Microenvironment

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT The healing of diabetic chronic wounds is hindered by multiple pathological barriers, including oxidative stress imbalance induced by hyperglycemia, persistent bacterial infection, and impaired neovascular function. This study developed an F127–HA–BiOCl@CeO2 (FHBC) hydrogel dressing with acoustic responsiveness, achieving tissue repair through

Prospective external validation of ADNEX and RMI for estimating risk of malignancy in adnexal masses in general gynecological settings: Danish multicenter study

Ultrasound in Obstetrics &Gynecology, Volume 68, Issue 2, Page 256-269, August 2026.
ABSTRACT Objectives The primary aims of this study were to validate externally the diagnostic performance of the Assessment of Different NEoplasias in the adneXa (ADNEX) model for distinguishing between malignant and benign adnexal masses, when used by non‐expert ultrasound examiners in general gynecological settings with a low prevalence of ovarian ...

Evaluating synthetic substitutes to reduce illegal harvesting and support species recovery

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract Providing synthetic substitutes is a widely promoted strategy to shift consumer demand away from wildlife products derived from threatened species. Yet, there is little evidence on whether product substitution prevents illegal or unsustainable harvesting and contributes to the recovery of threatened populations.

Changes in the transformative potential of action proposals in Finnish Red Lists from 1986 to 2019

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract Red lists provide critical knowledge regarding biodiversity decline, especially in Finland, where broad assessments have been made regularly since the 1980s. They deliver information on the threat status of species and ecosystems, propose actions to guide conservation policy, and have the potential to spur transformative change.

血小板及其受体促进卵巢癌转移的研究进展

Zhongguo shiyan zhenduanxue, 2019
卵巢癌转移所致的化疗抵抗是患者死亡的主要原因,主要通过两种途径:腹腔种植转移和循环肿瘤细胞(CTCs)介导的血行转移。最新研究发现,卵巢癌更易通过血行转移途径发生大网膜转移[1],血小板及其受体在这一过程中发挥至关重要的作用。肿瘤细胞利用血小板促进自身存活和转移的分子机制包括黏附受体分子如P选择素、整合素 ...

Policy Transfer and Lesson‐Drawing in Online Harms Regulation: From NetzDG to Online Safety

Politics &Policy, Volume 54, Issue 4, August 2026.
ABSTRACT Since Germany's passage of the Network Enforcement Act (NetzDG) in 2017, a growing number of countries have introduced online harms legislation requiring internet intermediaries to remove or address harmful or illegal content. Arguments about Germany's influence on other jurisdictions have relied on an undertheorized notion of policy transfer.

水通道蛋白与脑转移瘤周围水肿的相关性研究

Zhongguo shiyan zhenduanxue, 2007
目的研究人脑转移瘤及瘤周围脑组织水通道蛋白的表达和调控特征,认识水通道蛋白的异常表达在脑水肿形成和消除中的作用。方法对5例肺腺癌脑转移病例经手术切除的肿瘤组织提取总RNA并进一步行RT-PCR反转录扩增明确脑转移瘤组织中水通道蛋白的表达类型,再对肿瘤组织病理切片行相应水通道蛋白的免疫组化染色,测量切片的灰度值。结果水通道蛋白4（AQP4）在脑转移瘤周围脑组织高表达,而在转移瘤组织内部未见表达。在瘤组织周围,距离瘤组织较远的区域AQP4染色较浅,紧贴瘤组织的区域AQP4染色显著加深 ...

Basic income trials and the politics of scale: A research agenda

Policy Studies Journal, Volume 54, Issue 3, August 2026.
Abstract The growing popularity of basic income has led to extensive trials of the policy in numerous settings across the world. However, analysis of the politics of basic income, and in particular the political dynamics preceding and resulting from trial programs, lags. In response, we propose a research agenda that uses political scale to investigate

Powerful representation of the poor? German welfare associations' narrative advocacy during COVID‐19

Policy Studies Journal, Volume 54, Issue 3, August 2026.
Abstract The COVID‐19 pandemic sparked unprecedented experimentation in the German social assistance system, leading to changes previously considered impracticable by policymakers. This included a sanctions moratorium, easier access to benefits, and temporary cash transfers, all of which were advocated by welfare associations—key organized interests ...
