miRNA调控鹿茸生长发育的研究进展

open access: yes野生动物学报, 2020
鹿茸是雄性鹿科动物(除驯鹿外)特有的能够周期性再生的器官,其生长发育受到多种因素的共同调控。miRNA(microRNA)是一类在真核生物中发现的内源性的具有调控功能的非编码RNA,在基因表达调控、细胞周期、生物体发育等方面发挥着重要的调控作用。本文从miRNA的相关技术、鹿茸组织中miRNA的鉴定、miRNA对生长因子的调控作用、miRNA对鹿茸细胞增殖的作用以及miRNA对鹿茸再生调控的研究几个方面就现有miRNA对鹿茸生长发育的研究进行总结和展望,为今后鹿茸生长发育机理的诠释具有一定的意义。

When and why to give shorebirds a head start

open access: yesConservation Biology, EarlyView.
Abstract Headstarting is a translocation technique involving the hatching or rearing of wild eggs or young in captivity and the release of those individuals back to the wild at or before independence. It has been trialed as a conservation intervention for shorebirds over recent decades to improve the population trend of target populations by increasing

早产儿视网膜病变与胰岛素样生长因子-1的相关性研究进展

open access: yesZhongguo shiyan zhenduanxue, 2021
早产儿视网膜病变(Retinopathy of prematurity,ROP)属于增殖性视网膜病变,因早产儿视网膜发育尚未成熟,出生后的吸氧干预抑制了视网膜血管的继续生长,导致视网膜周边无血管区缺氧,而未血管化的视网膜发生纤维瘤增生、收缩,引起牵拉性的视网膜脱离和失明[1-2]。ROP的病理机制为视网膜血管发育不全和病理性新生血管形成,因此如何改善视网膜血管发育,抑制病理性的新生血管形成成为ROS的研究热点。胰岛素样生长因子-1(Insulin like growth factor-1,IGF-1 ...

The collective application of shorebird tracking data to conservation

open access: yesConservation Biology, EarlyView.
Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

Intact coastal nursery rearing amid climate‐driven phenological shifts in threatened salmon

open access: yesConservation Biology, EarlyView.
Abstract Literature linking phenology to climate has proliferated in recent decades and shows that climate change has reorganized seasonal opportunities worldwide. However, this literature often quantifies changes in point measures of timing (e.g., beginnings and peaks) without context about duration (e.g., rearing season length) or performance (e.g ...

生长激素缺乏症与特发性矮身材儿童血清IGF-1及25-(OH)D水平变化的研究

open access: yesZhongguo shiyan zhenduanxue, 2020
生长发育迟缓发病率在6%-8%之间[1],临床表现为身材矮小、代谢紊乱及器官功能异常,其中身高为生长发育衡量最明显的指标,而生长激素缺乏症(GHD)与特发性矮身材(ISS)也是儿科内分泌门诊最常见的疾病。本研究回顾性分析2016年1月至2019年1月间我院儿科内分泌门诊127例身高低于同年龄正常身高均值-2SD儿童临床资料,旨在探讨GHD与ISS患者血清胰岛素样生长因子-1(IGF-1)及25羟维生素D[25-(OH)VD]变化情况,为保障儿童的正常生长发育提供临床指导。

Twelve Years Revisited: Translanguaging as Relational Pedagogy for Sustaining Language Learning Motivation

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT This study examines how foreign language teachers’ beliefs about the medium of instruction and translanguaging evolve over time by revisiting three in‐service teachers twelve years after their initial interviews. Using a qualitative longitudinal design, the study traces how translanguaging was initially framed as pedagogically deficient but ...

The Pen is Mightier Than the Algorithm? A Multilevel Linguistic Comparison of LLM‐ and Human‐Translated Research Article Abstracts

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT Translating local research into English as a lingua franca (ELF) connects local scholarship with global readership, but this process remains constrained by language barriers. Large language models (LLMs) offer advanced accessible solutions, but their responsible integration into academic translation requires a deeper understanding of the ...
