The Roles of Bacteria and Fungi in Plant Nutrition02:11

The Roles of Bacteria and Fungi in Plant Nutrition

47.5K
Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.

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,...

Organisms exhibit remarkable metabolic diversity, categorized based on how they acquire energy and carbon. These strategies enable survival in various ecological niches and are essential for maintaining energy flow and nutrient cycling within ecosystems.Energy and Carbon SourcesOrganisms are classified as phototrophs or chemotrophs based on energy acquisition. Phototrophs use light as their energy source, while chemotrophs rely on oxidizing chemical compounds. Further differentiation arises...

Key Elements for Plant Nutrition

24.4K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Enteral Nutrition I: Orogastric and Nasogastric Feeding

1.6K
Enteral nutrition delivers nutrients directly to the stomach or small intestine through a tube. This method is appropriate for patients who cannot eat but still have a functioning digestive system. It is also beneficial for individuals with swallowing difficulties, anorexia, malabsorption, or those who have undergone gastrointestinal (GI) surgery.
Orogastric (OG) and nasogastric (NG) feeding are two standard methods used for enteral nutrition. Enteral nutrition is often preferred over...

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

1.1K
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.

Area of Science:

  • Nutrition Science
  • Biochemistry
  • Public Health

Background:

  • Folate (vitamin B9) is vital for human health, DNA methylation, and preventing anemia and developmental issues.
  • Folic acid fortification reduced neural tube defects (NTDs) but raises concerns about excess intake.
  • Potential risks of excess folic acid include masking vitamin B12 deficiency and promoting certain cancers.

Purpose of the Study:

  • To review the role of folate in human health.
  • To evaluate the benefits and risks of folic acid fortification.
  • To explore alternative strategies for folate supplementation.

Main Methods:

  • Literature review of folate metabolism and function.
  • Analysis of data on NTD prevalence post-fortification.
  • Examination of studies on adverse effects of excess folic acid.

Main Results:

  • Folic acid fortification significantly decreased NTD rates.
  • Excess folic acid intake is linked to vitamin B12 deficiency masking and increased cancer risk.
  • Optimal folate levels are crucial, and current fortification strategies may need re-evaluation.

Conclusions:

  • While folic acid fortification reduced NTDs, concerns about excessive intake necessitate a balanced approach.
  • Biofortification and other strategies may offer safer alternatives for folate delivery.
  • Further research is needed to optimize folate intake for public health.
