Article Synopsis
- The study examined how aging affects serum Thyrotropin (TSH) levels while considering thyroid-related factors.
- Researchers analyzed data from 343 patients who had thyroid surgery and underwent levothyroxine (LT4) treatment, categorized into young, middle-aged, and elderly groups.
- Results indicated that after withdrawal of LT4, older individuals had significantly lower stimulated TSH levels compared to younger groups, suggesting an important relationship between aging and TSH regulation.
Probiotic Gastrointestinal Transit and Colonization After Oral Administration: A Long Journey.
Front Cell Infect Microbiol
June 2021
Orally administered probiotics encounter various challenges on their journey through the mouth, stomach, intestine and colon. The health benefits of probiotics are diminished mainly due to the substantial reduction of viable probiotic bacteria under the harsh conditions in the gastrointestinal tract and the colonization resistance caused by commensal bacteria. In this review, we illustrate the factors affecting probiotic viability and their mucoadhesive properties through their journey in the gastrointestinal tract, including a discussion on various mucosadhesion-related proteins on the probiotic cell surface which facilitate colonization.
