Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

13.0K
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...

Anatomy of the Intestines01:23

Anatomy of the Intestines

84.7K
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...

Microorganisms in Medicine and Therapeutics

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.

Bacterial Flora of the Large Intestine01:29

Bacterial Flora of the Large Intestine

823
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.

What is Monogastric Digestion?01:50

What is Monogastric Digestion?

73.5K
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.

Irritable Bowel Syndrome I: Introduction01:17

Irritable Bowel Syndrome I: Introduction

598
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:
Altered...

科学分野:

  • 微生物学
  • 免疫学
  • 人間 の 健康

背景:

  • 微生物はしばしば病原性 (有害) または共生性 (有益) と分類される.
  • この二元分類は宿主と宿主微生物の 複雑な関係を過度に単純化しています
  • これらの相互作用のダイナミックな性質を理解することは 人間の健康にとって極めて重要です

研究 の 目的:

  • 宿主と微生物の相互作用の 複雑さを説明するために
  • 微生物の役割は 必ずしも有害で有益ではないことを 強調するためです
  • これらの相互作用が人間の健康に及ぼす状況特有の成果を強調する.

主な方法:

  • グラフィカルな概要表示
  • 具体的な実験データではなく 概念的なイラストにフォーカスします
  • 宿主-微生物関係のスペクトルの分析

主要な成果:

  • 宿主-微生物の相互作用はスペクトル上に存在し,単純な分類に挑戦しています.
  • 微生物の存在が健康に及ぼす影響は 特定の状況に大きく左右されます
  • "良い"微生物と"悪い"微生物の区別は しばしば曖昧である.

結論:

  • ヒトの健康における 微生物の役割は複雑で 文脈に依存しています
  • 単なる有害なレッテルや 有益なレッテルを超えて 微妙な理解が必要です
  • 特定の宿主-微生物の相互作用に関するさらなる研究は,健康上の結果を明らかにするために必要である.
