Notch Signaling Pathway03:14

Notch Signaling Pathway

4.4K
The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not...

Nephrotic Syndrome I : Introduction01:24

Nephrotic Syndrome I : Introduction

22
Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of...

Nondisjunction01:21

Nondisjunction

4.0K
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate correctly and move to the opposite poles of the cells. This produces daughter cells with abnormal chromosome numbers.  Nondisjunction is common during anaphase I or anaphase II of meiosis.  Mutations in synaptonemal complex proteins that attach homologous chromosomes increase the chances of nondisjunction in anaphase I of meiosis I. In contrast, mutations in topoisomerases and condensins that hold...

Prosopagnosia01:24

Prosopagnosia

247
Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...

Anorexia Nervosa01:28

Anorexia Nervosa

183
Anorexia nervosa is a complex and severe eating disorder characterized by an intense fear of weight gain, an unrelenting pursuit of thinness, and a distorted body image. It often leads to dangerously low body weight relative to an individual's age and height. This disorder is marked by significant physical and psychological consequences, making it one of the most life-threatening psychiatric illnesses.
Symptoms and Physical Effects
Individuals with anorexia nervosa commonly exhibit extreme...

Role Of Notch Signalling In Intestinal Stem Cell Renewal01:12

Role Of Notch Signalling In Intestinal Stem Cell Renewal

2.2K
Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...

Area of Science:

  • Neurology
  • Neuroscience
  • Cerebellar Research

Background:

  • Hermann Nothnagel's early research explored cerebellar function.
  • He documented cases linking tectal tumors to specific neurological deficits.

Purpose of the Study:

  • To highlight Nothnagel's seminal work on the cerebellum and associated clinical syndromes.
  • To review the historical and modern understanding of Nothnagel syndrome.

Main Methods:

  • Historical case review of Nothnagel's clinical observations.
  • Experimental studies on rabbits investigating motor ataxia.
  • Analysis of tumor-related neurological manifestations.

Main Results:

  • Nothnagel demonstrated the vermis's role in motor ataxia in 1876.
  • Four cases reported between 1879-1889 showed ophthalmoplegia and gait ataxia due to tectal tumors.
  • Nothnagel syndrome involves colliculi lesions and cranial nerve compression.

Conclusions:

  • Nothnagel's work established a link between cerebellar and midbrain structures.
  • Modern understanding attributes the ataxic component to dorsal midbrain abnormalities affecting specific neural pathways.
