科学领域:
- 微生物学 微生物学
- 在瘤学瘤学.
- 胃肠病学 胃肠病学
背景情况:
- 胃肠道微生物组是结直肠癌 (CRC) 的潜在生物标志物.
- 关于胃微生物对新辅助化疗 (NACT) 对胃癌反应的影响的研究有限.
研究的目的:
- 为了研究与胃癌患者的NACT反应相关的胃微生物群的差异.
- 为了确定潜在的微生物生物标志物来预测NACT结果.
主要方法:

What is Monogastric Digestion?
71.1K
The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists
160
Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy. SP binds and activates...
