Parentral Nutrition: Centeral and Peripheral Parental Nutrition01:27

Parentral Nutrition: Centeral and Peripheral Parental Nutrition

603
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,...

Genetic Screens02:46

Genetic Screens

5.5K
Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing  genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which...

Human Genetics

1.3K
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
The complex relationship between genetics and psychology is observable through common biological components such...

Area of Science:

  • Nutritional Science
  • Developmental Biology
  • Genomics

Background:

  • Dietary components interact with metabolism genes, influencing development and chronic disease risk.
  • Current understanding of gene-nutrient interactions in development and disease is limited.
  • Mammalian models (rodents) have limitations in speed and complexity for genetic nutrition research.

Purpose of the Study:

  • To highlight opportunities for using developmental models in human nutrition research.
  • To provide scientific rationale for employing these models.
  • To explore the function of gene products relevant to human nutrition.

Main Methods:

  • Review of existing literature on developmental models in nutritional science.
  • Presentation of zebrafish studies as an application example for obesity research.
  • Discussion of challenges and suggestions for standardizing diets in developmental models.

Main Results:

  • Developmental models, like zebrafish, offer advantages for studying gene-nutrient interactions.
  • Standardized diets are crucial for improving consistency and reproducibility across studies.
  • Alternative models have untapped potential for advancing nutrigenomics.

Conclusions:

  • Developmental models are valuable tools for uncovering gene functions related to human nutrition.
  • Standardization of dietary protocols is essential for robust findings in nutritional science.
  • Further research using diverse developmental models can significantly advance nutrigenomics and related fields.
