Diseases of the Liver and Gallbladder01:26

Diseases of the Liver and Gallbladder

2.0K
Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test

199
In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess...

Introduction to Developmental Psychology

1.5K
Developmental psychology explores the changes and continuities in human abilities throughout life, encompassing physical, cognitive, linguistic, and social dimensions. Human development is not restricted to growth, but includes aspects of decline, particularly in physical abilities as individuals age. Developmental psychologists seek to understand how people change as they age and how their mental and social skills evolve.Developmental MilestonesA key concept in developmental psychology is...

Three Developmental Domains01:29

Three Developmental Domains

1.1K
Human development is typically examined across three main domains: physical, cognitive, and socio-emotional. These domains represent the significant areas of change and continuity throughout the lifespan, from infancy to late adulthood.
Physical Development
Physical processes, also known as maturation, encompass the biological changes that occur across an individual's life. These changes begin with genetic inheritance and continue through various stages, including growth in height and weight,...

Ethers from Alcohols: Alcohol Dehydration and Williamson Ether Synthesis

12.9K
Overview
Ethers can be prepared from organic compounds by various methods. Some of them are discussed below,
Preparation of Ethers by Alcohol Dehydration
In this method, in the presence of protic acids, alcohol dehydrates to produce alkenes and ethers under different conditions. For example, in the presence of sulphuric acid, dehydration of ethanol at 413 K yields ethoxyethane, whereas it yields ethene at 443 K.

Area of Science:

  • Hepatology
  • Molecular Biology
  • Regenerative Medicine

Background:

  • Alcohol-induced steatohepatitis (ASH) elevates risks for severe alcoholic hepatitis and cirrhosis.
  • Mechanisms of ASH pathogenesis and progression remain largely unknown.
  • Liver cell plasticity is implicated in ASH development.

Purpose of the Study:

  • To investigate the role of morphogenic signaling pathways in ASH pathogenesis.
  • To understand how these pathways contribute to liver injury and repair.
  • To identify potential therapeutic targets for optimizing liver regeneration in ASH.

Main Methods:

  • Analysis of reactivated morphogenic signaling pathways in injured adult livers.
  • Examination of cell fate modulation during fetal development and in adult liver progenitors.
  • Assessment of the impact of dysregulated signaling on liver repair processes.

Main Results:

  • Morphogenic signaling pathways, crucial for fetal development, are reactivated in injured adult livers.
  • Overactivation of these pathways leads to dysregulated liver repair.
  • This dysregulation increases mortality by promoting acute liver failure and fibrosis.

Conclusions:

  • Reactivated morphogenic signaling pathways are critical in ASH progression.
  • Dysregulated liver repair due to these pathways contributes to poor outcomes.
  • Targeting these pathways offers a potential strategy for treating ASH and preventing liver failure.
