背景:
- 微生物群の研究はしばしば相対的多量データに依存し,これは微生物の総細胞数を捉えていません.
- 腸内微生物群の構成と変化を正確に理解するには 絶対的な微生物の豊富さを理解することが重要です
研究 の 目的:
- 比較的豊富なデータから糞便の微生物量 (微生物細胞/グラム) を予測する機械学習モデルを開発する.
- 腸内微生物群の変動と宿主因子や疾患との関連を決定する要因として排泄中の微生物の役割を調査する.
主な方法:

- 予測モデルは,大規模なメタゲノムデータセット (n = 34,539) に適用された.
- 宿主因子と疾患状態との微生物負荷の関連性を評価するために,統計的分析が行われました.
主要な成果:
- 腸内微生物群の変化の主な決定因子として,糞便の微生物量が特定されました.
- 微生物の負荷は,年齢,食事,薬剤などの宿主要因と有意な関連性を示した.
- 病気の状況よりも 微生物の負荷の変化が 患者の微生物群の変化を説明し 病気に関連した種の重要性を減少させたのです

01:23Anatomy of the Intestines
71.4K
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...

01:29Bacterial Flora of the Large Intestine

The gut microbiome is formed by a vast and diverse community of bacteria that colonizes our large intestine. These bacteria start residing in the gut from birth and continue diversifying throughout life, influenced by factors such as diet, lifestyle, and stress. The gut bacterial community also includes bacteria from food and those that enter the colon through the anus.
The normal gut flora of the colon plays a critical role in generating essential vitamins such as vitamins K, B5, and B7.

01:17Irritable Bowel Syndrome I: Introduction
248
Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:

01:26Factors Affecting the Risk of Infection
11.4K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...
