Rare Metals, EarlyView.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 ...

Mokslo Taikomieji Tyrimai Lietuvos Kolegijose, 2016 Perteklinio laikinųjų apsaugos priemonių naudojimo problematika yra gana aktuali Lietuvos teisinėje sistemoje, kadangi bene kiekvienas praktikuojantis teisininkas, gindamas kliento interesus, kaip šabloninę ieškinio dalį prideda ir prašymą taikyti laikinąsias apsaugos priemones. Dėl tokio šabloniškumo dažnai iškyla klausimas, ar taikant

Improving the Parole System from the View of the Restorative Justice [PDF]
, 2015 假释是刑罚执行中的一项重要制度，具有调节宣告刑长短、避免“刑罚过剩”、激励罪犯改造复归、修复受损社会关系、维护监狱管理秩序等重要功能。我国现行假释制度存在相关主体程序参与不足、裁判中事实调查与说理不足、假释裁定与假释考验期相脱节、监督权虚设化等弊病，制约着假释功能的实现。假释关注罪犯的复归、社会矛盾的缓和与受损社会关系的修复，在这一点上与修复性司法理念存在功能上的契合，将修复性司法理念融入假释制度，构建在法院主导下由执行机关、检察机关、罪犯、被害人、社区及罪犯与被害人的家人、近亲属共同参与 ...

Rare Metals, EarlyView.ABSTRACT Recently, cobalt/nitrogen co‐doped materials have emerged as heterogeneous catalysts to activate peroxymonosulfate (PMS) and have been applied to advanced oxidation processes for environmental remediation. However, their recyclability and reusability remain major barriers to practical application.

Shuitu Baochi Xuebao, 2005 土壤铜污染有自然来源和人为来源。铜污染土壤中有机质、Fe／Al氧化物对铜的专性吸附，是影响土壤中铜生物有效性的主要因素。近年来，我国原生植物修复材料如海州香薷、鸭跖草、酸模、紫花香薷在国内铜污染土壤的研究中得到广泛应用。其中．采用海州香薷开展铜污染土壤植物修复机理和修复技术的研究，已从实验室水培、盆栽试验的生长反应特性、耐及解铜毒的生理生化反应，进展到室外大田修复的示范工程及技术推广阶段。紫花香薷在重金属复合污染土壤上，也有修复前景。开展植物修复材料的产后处置研究，综合利用和深加工，增大植物修复材料价值，

Synthesis and Properties of Self-healing Polymers and Electrically Conductive Composites Based on Hydrogen-bonding [PDF]
, 2015 通过模仿生物体自愈合的特性，人工合成可自行感知和修复损伤的聚合物材料是一项富有深远意义的研究。目前聚合物材料在加工和使用过程中容易受到各种外界因素的破坏并产生难以监测的微裂纹，而这些微裂纹正是材料性能退化的起点。作为一种新颖的智能仿生材料，自修复聚合物能够感知并修复这类损伤，避免材料受到进一步破坏，延长材料使用寿命，消除安全隐患，节约维修成本。然而，目前研究的自修复高分子材料大多为绝缘体，使得其在导电领域中的应用受到限制。随着导电高分子材料在电子器件、传感器、能源、信息、航空等领域的广泛应用 ...

Microbial Degradation of Petroleum Hydrocarbons by Acinetobacter sp. BZ-15,Isolated from Contaminated Soil [PDF]
, 2016 本研究旨在从土壤中筛选高效石油烃降解菌株,并对其系统分类和降解特性进行研究,为石油污染的原位修复奠定基础.该研究从滨州油井溢油污染土壤样品中分离得到一株高效石油烃降解菌株BZ-15,对菌株BZ-15进行形态观察、16S r RNA基因序列分析及系统发育树分析;对该菌株的生长特性进行研究;通过GC-MS分析其对原油组分中不同碳原子饱和烃的降解特性;同时研究吐温-20对其生长及降解特性的影响;对该菌株中的烷烃羟化酶基因alk M进行了克隆.结果表明,菌株BZ-15为不动杆菌属(Acinetobacter ...

World Medical &Health Policy, EarlyView.ABSTRACT Population aging is a problem that countries around the globe are facing; it comes with complex healthcare needs. Different countries take different approaches to solving these issues. In the United States, proposed legislation related to hospice and palliative care emerged from a history of hospice fraud and specialty physician shortages.

The role of jumping translocation breakpoint gene promoting instability of genome and the biological function of its protein and potential clinical value [PDF]
, 2014 染色体不稳定性是大多数肿瘤细胞特别是实体瘤细胞和体外转化细胞的基本特征。其表现形式包括整条染色体的获得或缺失，杂合缺失，染色体易位重排，基因扩增等。目前认为染色体不稳定是肿瘤形成的始发因素，出现在肿瘤进展的早期阶段。体内外各种损伤刺激导致的基因组DNA链的断裂是染色体不稳定的根本原因。我们的研究发现，跳跃易位断裂点基因（JTB）在胃癌、肝癌中存在广泛的基因扩增和基因易位行为，而基因的扩增和易位是DNA双链断裂后异常修复的最终结果。JTB基因的断裂易位将导致其编码跨膜结构域的基因序列丢失 ...

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Articular cartilage regeneration remains a significant challenge because of its limited intrinsic healing capacity and the inadequacy of conventional treatments for restoring structural and functional integrity. In this study, a novel injectable composite hydrogel scaffold was designed to mimic the extracellular matrix (ECM) of native ...
