概括
雌性周期不会影响雌性大鼠的氧化摄入量或渴望化. 轨道前皮层 (OFC) 仍然对化氧化在女性寻求的过程至关重要,类似于男性.
科学领域:
- 神经科学是一个神经科学.
- 成研究 研究成研究
- 行为药理学行为药理学
背景情况:
- 在老鼠中观察到氧化渴望的潜伏,禁欲后寻求药物的逐渐增加.
- 在雄性大鼠中,轨道前皮层 (OFC) 对这种现象至关重要.
- OFC的作用和雌性大鼠雌性月经周期的影响仍然未被探索.
研究的目的:
- 为了研究雌性大鼠化周期对化氧化寻找的效果.
- 为了确定OFC在化氧化寻找中的作用是否延伸到雌性大鼠.
- 在此背景下,评估化学遗传学在研究OFC功能的有效性.
主要方法:
- 在雌性大鼠中,在雌性老鼠的雌性周期的不同阶段评估了氧化自给和渴望的潜伏.
- 使用JHU37160 (J60) 与专用药物 (DREADDs) 独家激活的设计受体进行OFC的化学遗传失活.
- 对照组接受了单独的J60或没有DREADD治疗.
主要成果:
- 在自我管理培训期间,氧化的摄入量在雌性期,雌性期前期和雌性期中没有差异.
- 在非雌性和雌性雌性老鼠之间,化氧化寻求水平与非雌性雌性老鼠相似.
- 化学遗传性OFC无活化显著降低了化氧化寻求,而J60在对照大鼠中没有影响.
结论:
- 在研究的条件下,雌性大鼠的雌性周期不会影响氧化摄入量或氧化渴望的潜伏期.
- 轨道前皮层 (OFC) 对于在雌性大鼠中化氧化寻找至关重要,反映了雄性大鼠的发现.
- 这些结果突出了OFC在不同性别的成相关行为中的保留作用.

Hormonal Control of the Ovarian Cycle
555
The ovarian cycle is meticulously regulated by the hypothalamic-pituitary-gonadal axis. This cycle orchestrates the release of a mature oocyte, essential for reproduction.
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...

Opioid Receptors: Overview
984
Opioid receptors, including the mu (μ, MOR), delta (δ, DOR), and kappa (κ, KOR) types, belong to the rhodopsin family of G protein-coupled receptors. These receptors are located throughout the central and peripheral nervous systems and in non-neuronal tissues such as macrophages and astrocytes. Opioid receptor ligands can be categorized into agonists or antagonists. Highly selective agonists include [d-Ala2, MePhe4, Gly(ol)5]-enkephalin or DAMGO for MOR, [D-Pen2,...

Opioid Analgesics: Synthetic and Semisynthetic Opioids
326
Synthetic and semisynthetic opioids are pivotal in pain management and tackling opioid addiction. Semisynthetic opioids, including morphinans (morphine derivatives), oxycodone, oxymorphone, hydrocodone, and hydromorphone, have improved pharmacokinetic profiles compared to morphine. Additionally, heroin and 6-MAM (6-Monoacetylmorphine) show better CNS penetration than morphine due to heightened lipid solubility. Hydromorphone, a potent opioid, undergoes hepatic metabolism to form the active...
