- 环境声学环境声学
背景情况:
- 动物园越来越多地利用音乐晚会等非营业时间的活动来增加游客人数.
- 这些事件产生的人为噪音引发了对对动物福利的潜在负面影响的担忧.
- 婆罗洲猩猩是保护关注的一种物种,因此它们在囚禁中的福利尤其重要.
研究的目的:
- 研究婆罗洲猩猩对动物园现场音乐活动的生理应激反应.
- 通过便葡萄糖皮质激素代谢物 (FGCM) 度来测量压力.
- 在事件期间,将压力水平与内的声学数据相关联.
主要方法:
- 在四个周末的现场音乐活动中,从六只婆罗洲猩猩收集了便样本.
- 围环境的声学分析是在24小时内进行的,比较了事件和非事件时期.
- 便葡萄糖皮质类代谢物 (FGCM) 水平被量化并根据声学指标 (LAeq,LA10,LA90) 进行统计分析.
主要成果:
- 隔离室的通风系统噪音掩盖了现场音乐,但在活动时间,整体噪音水平 (LAeq,LA10,LA90) 较高.
- 在事件日,群体平均FGCM度较高,但个体分析显示没有显著差异.
- 随着个体声学水平 (LAeq) 的上升,FGCM度显著增加,一些人对更大噪音的天气做出了更高的反应.
结论:

01:25Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids
1.5K
Inhaled corticosteroids (ICS) are anti-inflammatory drugs used primarily in treating persistent asthma and providing long-term maintenance. They target the bronchial mucosa, the lining of the airways, to control inflammation, a critical factor in asthma progression and exacerbation.
ICS work through a multifaceted mechanism of action. They suppress the inflammatory response caused by the proliferation of TH cells. They also reduce the transcription of the IL-2 gene, which is involved in the...

01:31Hormones of the Adrenal Glands
4.4K
Adrenal hormones play a pivotal role in maintaining the body's electrolyte balance and orchestrating responses to stress, showcasing the intricate functions of the adrenal cortex and medulla.
The adrenal cortex, a powerhouse of hormone synthesis, generates over two dozen corticosteroid hormones. The zona glomerulosa produces mineralocorticoids, exemplified by aldosterone, influencing the electrolyte composition of body fluids. The synthesis of glucocorticoids such as cortisol and...

65.3K
The response to stress—be it physical or psychological, acute or chronic—involves activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis. The HPA axis is part of the neuroendocrine system because it involves both neuronal and hormonal communication. Its function is to regulate homeostatic systems—metabolic, cardiovascular, and immune—providing the necessary means to respond to a stressor.

01:27Adrenal Gland Disorders
2.8K
Adrenal gland disorders manifest when the production of adrenal hormones deviates from the norm, resulting in either excessive or insufficient concentrations.
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...
