The Mammary Glands01:12

The Mammary Glands

1.3K
The female breast is a hemispheric projection of variable size positioned anterior to the pectoralis major and serratus anterior muscles. A fascia layer composed of dense, irregular connective tissue connects it to these muscles.
Each breast features a pigmented projection known as the nipple, through which milk emerges via closely spaced openings of ducts, referred to as lactiferous ducts. Surrounding the nipple is a circular pigmented area of skin named the areola, which appears rough due to...

Anatomy of the Intestines01:23

Anatomy of the Intestines

83.9K
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...

Cancer Prevention

6.3K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Proteins: Dietary Sources and Requirements01:28

Proteins: Dietary Sources and Requirements

798
Consuming animal-based products offers high-quality proteins that contain optimal levels and combinations of essential amino acids, crucial for tissue repair and growth. Foods like eggs, milk, fish, and most meats are a source of complete proteins. Legumes and cereals are abundant in proteins; however, they typically lack a full range of essential amino acids. As a result, they are considered incomplete protein sources. Some plant sources like soybeans, quinoa, and amaranth do contain complete...

Parentral Nutrition: Centeral and Peripheral Parental Nutrition

Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

323
Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.
Nasointestinal Feeding
Nasointestinal feeding involves placing a tube...

Summary

Breast milk contains beneficial microbes that help develop infant gut microbiota and immune factors. This supports infant health and may reduce the risk of chronic diseases later in life.

Area of Science:

  • Microbiology
  • Immunology
  • Pediatrics

Background:

  • Human breast milk is a natural infant nutrition source, containing macro/micronutrients and microorganisms.
  • The milk microbiota originates from the mother, infant's mouth, and environment, with common bacteria including Staphylococci, Streptococci, Lactobacilli, and Bifidobacteria.
  • These microbes are crucial for developing infant gut microbiota and immune regulatory factors.

Purpose of the Study:

  • To review the benefits of breastfeeding.
  • To highlight the role of breast milk microbiota in infant health.
  • To explore the interaction between breast milk microbiota and the infant immune system.

Main Methods:

  • Literature review of existing studies on breast milk microbiota and infant immunity.
  • Analysis of the composition and function of microorganisms in human milk.
  • Examination of the immunological impact of breast milk microbiota on infants.

Main Results:

  • Breast milk microbiota contributes to the establishment of infant gut microbiota.
  • Microorganisms in breast milk stimulate the production of immune factors like cytokines and lactoferrin.
  • These factors play a role in immune system development and regulation in infants.

Conclusions:

  • Breast milk microbiota is essential for infant gastrointestinal and immune development.
  • The interaction between breast milk microbiota and the infant immune system may reduce the risk of chronic diseases.
  • Breastfeeding provides significant health benefits through its complex microbial and immunological contributions.
