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

1.0K
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.

Nasointestinal feeding involves placing a tube...

Area of Science:

  • Gerontology
  • Nutritional Epidemiology
  • Public Health

Background:

  • The population of adults aged 85 and over is rapidly increasing globally.
  • This demographic experiences heightened risks of malnutrition, multimorbidity, and disability.
  • Diet is a modifiable factor influencing age-related conditions like sarcopenia and functional decline.

Purpose of the Study:

  • To investigate the relationship between diet and physical functioning in very old adults.
  • To identify nutritional requirements specific to the oldest-old.
  • To address the evidence gap concerning dietary patterns, protein, vitamin D, and cognitive function in later life.

Main Methods:

  • Review of recent findings in nutritional epidemiology.
  • Inclusion of data from unique cohort studies like the Newcastle 85+ Study and the Life and Living in Advanced Age study.
  • Focus on the diet-physical functioning relationship in adults aged 85+.

Main Results:

  • Analysis of dietary patterns and nutrient intakes in the very old.
  • Exploration of how nutrition influences physical and cognitive maintenance in advanced age.
  • Updated insights from large-scale aging studies.

Conclusions:

  • Diet plays a crucial role in maintaining physical and cognitive function in the very old.
  • Further research is needed to fully understand specific nutrient needs and dietary patterns for this age group.
  • The findings emphasize nutrition as a key modifiable factor for healthy aging.
