Parentral Nutrition: Centeral and Peripheral Parental Nutrition01:27

Parentral Nutrition: Centeral and Peripheral Parental Nutrition

1.2K
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,...

Epigenetic Regulation

Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

Epigenetic Regulation

4.0K
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

Nature and Nurture01:10

Nature and Nurture

22.6K
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

Overview of Protein Metabolism01:21

Overview of Protein Metabolism

4.3K
Proteins are broken down into amino acids during digestion. Unlike fats and carbohydrates, which are stored for later use, proteins are not. Instead, amino acids are either used to produce ATP through oxidation or contribute to the creation of new proteins for the growth and repair of the body. Any surplus amino acids from the diet are converted into glucose or triglycerides rather than excreted.
Amino acids play various roles in the body once they are absorbed into cells. They are restructured...

Regulation of Food Intake01:30

Regulation of Food Intake

3.0K
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

Area of Science:

  • Nutritional epigenetics
  • Developmental origins of health and disease

Background:

  • Epigenetics modulates gene expression without altering DNA sequence.
  • In utero malnutrition can lead to epigenetic alterations, potentially influencing adult disease susceptibility and inheritance.
  • The precise mechanisms linking nutritional factors to epigenetic changes and subsequent health outcomes require further elucidation.

Purpose of the Study:

  • To review the association between suboptimal nutrition during development and increased risk of adult-onset chronic diseases.
  • To focus on epigenetic modifications (changes in genome function without DNA sequence alteration) as a key link.
  • To discuss drivers of phenotypic changes and epigenetic markers established during early life reprogramming.

Main Methods:

  • Literature review and synthesis of current research on epigenetics and nutrition.
  • Focus on epigenetic mechanisms, including DNA methylation and histone modifications.
  • Analysis of studies investigating the impact of early-life nutrition on long-term health outcomes.

Main Results:

  • Suboptimal nutritional environments in utero can establish persistent epigenetic marks.
  • These epigenetic changes can alter gene expression patterns, contributing to adult-onset chronic illnesses.
  • Identification of specific epigenetic markers and reprogramming events associated with nutritional insults.

Conclusions:

  • Epigenetic modifications represent a critical interface between early-life nutrition and adult health.
  • Understanding these mechanisms provides insights into disease etiology and inheritance.
  • This knowledge paves the way for novel preventative strategies and personalized medicine approaches targeting epigenetic pathways.
