Abstract Background Canine pyoderma is one of the most common presentations in small animal practice, frequently leading to antimicrobial prescribing. Objectives To provide clinicians with antimicrobial treatment guidelines for staphylococcal pyoderma, including those involving meticillin‐resistant staphylococci.

Reactive oxygen species act as signaling molecules to control root hair initiation and tip growth
Summary Root hairs (RHs) increase the surface area of roots, facilitating nutrient and water uptake and plant anchorage. RHs form from root epidermal cells and elongate by polar tip growth. Reactive oxygen species (ROS) have recently been implicated as important signals that drive RH formation and elongation using both genetic and imaging approaches ...

Background – Canine interdigital furunculosis (CIF) is a complex, relapsing inflammatory condition, typically complicated by deep bacterial infections requiring prolonged systemic antibiotics. Hypothesis/Objectives – This split‐body study, where dogs acted as their own control, evaluated whether the adjunctive use of fluorescent light energy (FLE ...

Preparation and evaluation of mitomycin C-phospholipid complex-based novel targeted nanoscaled drug delivery systems [PDF]
丝裂霉素C是一种临床常用的广谱抗生素类抗癌药物。然而丝裂霉素C在静脉注射给药中受到诸多限制,如生物利用度极低、体内半衰期极短、非特异性全身分布、严重毒副作用等,使其最终到达肿瘤部位的血药浓度仅为静脉给药浓度的1/20左右。因此,如何最大限度地提高药物疗效以杀伤肿瘤细胞同时把药物毒副作用降低到最低程度无疑是丝裂霉素C在癌症化学治疗中的重要问题。本研究立足于自组装技术,我们设计并开发了基于丝裂霉素C-磷脂复合物的单药纳米传递系统以及基于丝裂霉素C(主药)-磷脂复合物和甲氨蝶呤前药(副药)的双药纳米传递系统 ...

miRNA-17~92 Inhibits Colorectal Cancer Progression by Targeting Angiogenesis [PDF]
miRNA中的miR-17~92簇在包括结直肠癌(Colorectalcancer,CRC)等人类癌症中广泛表达。已有的研究表明miR-17~92在某些肿瘤模型中可促进肿瘤发生和癌组织血管生成。然而,其在CRC发生和进展中的作用仍然未知。在本研究中,我们意外发现,在用氧化偶氮甲烷(AOM)和右旋糖酐硫酸钠(DSS)诱导的CRC动物模型中,大肠、小肠上皮细胞过表达miR-17~92的转基因小鼠可见肿瘤体积变小、肿瘤血管减少。进一步研究发现,miR-17 ...

Background – Mycobacterium cell wall fraction (MCWF) is derived from nonpathogenic Mycobacterium phlei and is used as an immunomodulatory compound in clinical practice, yet its mode‐of‐action requires further research. Objective – To evaluate the host response to MCWF in canine peripheral blood mononuclear cells (PBMCs) by using enzyme‐linked ...

Translocation of Mixed lineage kinase domain-like protein to plasma membrane leads to necrotic cell death [PDF]
在最近的研究结果中,混交激酶域蛋白Mlkl(mixedlineagekinasedomain-like protein)被确认为Rip3蛋白在细胞坏死信号通路中的下游蛋白。然而,Mlkl如何 在细胞坏死信号通路中行使怎样的功能,尚未明晰。通过在Mlkl基因敲除的细 胞中回补Mlkl蛋白进行一系列的研究,实验数据表明,Mlkl蛋白氨基端结构域 是其在坏死通路中行使功能的必要部分。在坏死过程中,Mlkl蛋白形成多聚体; 或者在细胞中利用分子生物学手段人为地诱导形成Mlkl蛋白多聚体,也能够引 起细胞坏死 ...
