[Abstract]  Fast scan cyclic voltammetry (FSCV) is an electrochemical technique that allows sub-second detection of oxidizable chemical species, including monoamine neurotransmitters such as dopamine, norepinephrine, and serotonin. This technique has been used to record the physiological dynamics of these neurotransmitters in brain tissue, including their rates of release and reuptake as well as the activity of neuromodulators that regulate such processes. This protocol will focus on the use of ex vivo FSCV for the detection of dopamine within the nucleus accumbens in slices obtained from rodents. We have included all necessary materials, reagents, recipes, procedures, and analyses in order to successfully perform this technique in the laboratory setting. Additionally, we have also included ... [摘要]  快速扫描循环伏安法(FSCV)是一种电化学技术,可以亚秒检测可氧化的化学物质,包括单胺类神经递质,如多巴胺,去甲肾上腺素和血清素。 该技术已被用于记录这些神经递质在脑组织中的生理动态,包括它们的释放和再摄取速率以及调节这些过程的神经调节剂的活性。 该方案将集中于使用离体 FSCV检测从啮齿动物获得的切片中的伏隔核内的多巴胺。 我们已经包含了所有必要的材料,试剂,配方,程序和分析,以便在实验室环境中成功地执行该技术。 此外,我们还提供了一些警示点,我们认为这些警告点对于那些在该领域的新手有帮助。

【背景】由于首先将用于检查生理系统的电特性的能力用于临床前科学研究,因此已经开发了许多用于研究突触生理学的技术。从鱿鱼轴突电生理记录的早期到现在的快速扫描循环伏安法(FSCV)在人类帕金森病患者中进行(Kishida et al。,2016; Lohrenz et al。,2016),该领域在相对较短的时间内取得了重大进展。该协议的重点是FSCV,是物理学家,分析化学家和神经科学家之间40多年的创新和合作的技术成果。早在19世纪(Bard和Zoski,2000年),电化学与Michael Faraday和Alessandro Volta一起诞生(Bard and Zoski,2000),直到20世纪20年代,Jaroslav ...

Root-knot Nematode Penetration and Sclareol Nematicidal Activity Assays

[Abstract]  Plant parasitic nematodes parasitize roots and/or stems of various plants thereby inhibiting absorption of nutrients and moisture. In particular, root-knot nematodes (RKN) are a group of the most devastating pests. Various techniques, such as soil sterilization, cultivation of resistant crops, and chemical application, have been developed to control damage caused by RKN. Among these techniques, diminish by chemicals that induce or activate host defense to RKN is an attractive method because of its potential to reduce the environmental burden caused by crop protection. Sclareol, a diterpene, was identified as a chemical that induces resistance to RKN (Fujimoto et al., 2015). Here we provide a protocol for assessing the impact of sclareol on the penetration of RKNs into tomato and Arabidopsis ... [摘要]  植物寄生线虫寄生于各种植物的根和/或茎,从而抑制营养物和水分的吸收。 特别地,根结线虫(RKN)是最具破坏性的害虫的组。 已经开发了各种技术,例如土壤灭菌,抗性作物的栽培和化学施用,以控制由RKN引起的损害。 在这些技术中,诱导或激活RKN的宿主防御的化学物质的减少是有吸引力的方法,因为其具有减少作物保护所引起的环境负担的潜力。 Sclareol,一种二萜,被鉴定为诱导对RKN的抗性的化学物质(Fujimoto等人,2015)。 在这里我们提供了评估香紫苏醇对RKNs对番茄和拟南芥根的渗透以及化学物对线虫的直接杀线虫影响的影响的方案。 该方案可用于其它线虫抗性诱导化学品。
