Abstract DNA barcode‐based species identification has become pivotal in biodiversity research. Current barcoding‐based deep learning methods have advantages in species identification but exhibit significant limitations. By using COI barcoding alone, previous studies were unable to fully capture species identification features. Prior methods showed that

微小RNA(miRNAs)是一类内源性的高度保守的非编码蛋白质的单链小分子RNA。它们通过与靶基因结合,在转录后水平导致靶mRNA的翻译抑制或降解,调节靶基因的表达[1]。微小RNA-92(miR-92)是近年来发现的一种新型miRNA ...

Genomic responses to increased temperature and pollinator selection in Brassica rapa L.
Summary Rapid environmental change reshapes both abiotic stress and biotic interactions, yet it remains unclear how these combined forces structure plants' genomic adaptation. In particular, the joint influence of temperature and pollinator identity, two ecological axes undergoing simultaneous global shifts, has rarely been quantified at genomic ...

胃癌患者血清中miR-204水平变化及与幽门螺杆菌感染的关系
幽门螺杆菌(Hp)感染已经被国际癌症研究机构列为第一类癌病致病原[1]。目前大量研究已证实Hp感染与胃癌发生、发展密切相关,但具体机制尚不清楚。微小RNA(miRNA)是一种单链RNA,目前研究认为其具有非编码性和高度保守性[2]。Calin[3]研究发现有超过半数的miRNA的基因所在区域与肿瘤有关,诸如杂合子缺失的微小区域 ...

ABSTRACT Skin wound injuries are often accompanied by bacterial infections and severe inflammation. Especially, M1‐type macrophages at the wound site can trigger a cascade of inflammatory responses, mediating a vicious cycle of inflammation. Meanwhile, hypoxia further exacerbates vascular damage and constriction in the wound microenvironment, thereby ...

ABSTRACT Periodontitis is a chronic infectious oral disease triggered by periodontopathogenic bacteria, resulting in the progressive inflammation and destruction of the tissues surrounding teeth. To achieve reprogramming of the infectious microenvironment for periodontitis therapy, a nanoformulation was proposed by loading polydopamine (PDA) with ...

Advances in Elemene Nanodelivery Systems: From Material Design to Disease Treatment
ABSTRACT Elemene (ELE) is a bioactive sesquiterpenoid extracted from traditional Chinese herbs, demonstrating broad‐spectrum antitumor, anti‐inflammatory, and analgesic properties with significant therapeutic potential. However, its clinical utility is constrained by inherent physicochemical limitations, including volatility and hydrophobicity, which ...

胶质瘤(glioma)是起源于脑部或脊髓的神经系统肿瘤,根据组织细胞形态学特征可分为不同的亚型。胶质瘤组织病理学分类仍存在较大异质性,同一病理类型患者其分子学改变、病程演进、治疗反应等仍不尽相同[1]。因而,深入研究胶质瘤的分子病理机制是近年的研究热点之一。微小RNA(micro RNAs,miRNAs)为长度19-22个核苷酸组成的非编码RNA,通过与靶基因信使RNA结合,进而调控基因的转录后表达 ...
