Anatomy of the Intestines

Anatomy of the Intestines

Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

What is Monogastric Digestion?

What is Monogastric Digestion?

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.

Horizontal Gene Transfer

Horizontal Gene Transfer

Horizontal gene transfer (HGT) is a process where genetic material moves between organisms within the same generation, unlike vertical gene transfer, which occurs from parent to offspring. HGT plays a crucial role in microbial evolution, adaptation, and survival, particularly in shared environments like the human gut.Mobile genetic elements such as plasmids, prophages, integrons, insertion sequences, and transposons facilitate this process. HGT occurs through three primary mechanisms:...

Area of Science:

Microbiome research
Human migration studies
Public health

Background:

International migration leads to lifestyle changes, increasing obesity and diabetes risk in foreign-born individuals.
Changes in the microbiome are a potential mechanism linking environmental shifts to health conditions like diabetes and obesity.
Previous studies indicate that unfavorable microbiome alterations can predispose individuals to various diseases.

Purpose of the Study:

To investigate the relationship between international human migration and changes in microbiome composition.
To review existing literature on how migration impacts the gut, oral, or oropharyngeal microbiome.

Main Methods:

A systematic literature review was conducted using PubMed and Web of Science.
Search terms included 'microbiome' and 'migration'.
Included studies examined the microbiome of internationally migrating individuals.

Main Results:

Nine articles met the eligibility criteria, mostly focusing on migration from non-Western to Western countries.
Migrants showed altered microbiome composition compared to both their country of birth's non-migrants and the host country's native-born population.
Microbiome differences were associated with duration of stay, country of birth, age at migration, and resettlement country.

Conclusions:

International migration may induce significant changes in human microbiome composition.
Microbiome alterations represent a plausible pathway to understand health changes observed after migration and resettlement.
Further research into microbiome characteristics is warranted to examine post-resettlement health outcomes.
