Key Elements for Plant Nutrition02:35

Key Elements for Plant Nutrition

18.8K
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...

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...

Chronic Kidney Disease III: Interprofessional Care

41
Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

Vitamins

772
Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced...

Requirements for Human Life01:26

Requirements for Human Life

8.3K
The Earth and its atmosphere have provided humans with air, water, and food, but these are not the only requirements for survival. Humans also require a specific range of temperature and pressure that the Earth and its atmosphere provides.
Oxygen
Atmospheric air is only about 20 percent oxygen, but that oxygen is a key component of the chemical reactions that keep the body alive, including the reactions that produce ATP. Brain cells are susceptible to a lack of oxygen because they require a...

Area of Science:

  • Neonatal Nutrition
  • Pediatric Micronutrient Metabolism

Background:

  • Premature neonates have increased nutritional requirements and limited stores, risking deficiencies.
  • Assessing micronutrient needs and serum levels in preterm infants is difficult due to limited data.
  • Parenteral and enteral nutrition shortages complicate micronutrient delivery in neonates.

Purpose of the Study:

  • To review the importance of select micronutrients for preterm neonates.
  • To highlight challenges in micronutrient supplementation and repletion strategies for this population.
  • To focus on micronutrients with limited evidence and complex management.

Main Methods:

  • Literature review of scientific articles and clinical guidelines.
  • Analysis of data on micronutrient requirements in preterm infants.
  • Discussion of current challenges and evidence gaps in neonatal micronutrient therapy.

Main Results:

  • Specific micronutrients are critical for preterm infant growth and development.
  • Current data on optimal micronutrient levels and delivery methods are insufficient.
  • Supplementation strategies require careful consideration due to potential toxicities and absorption issues.

Conclusions:

  • Adequate micronutrient provision is essential for preterm neonate growth.
  • Further research is needed to establish precise micronutrient requirements and safe supplementation protocols.
  • Addressing these nutritional challenges is vital for improving long-term outcomes in premature infants.
