Notch Signaling Pathway03:14

Notch Signaling Pathway

6.9K
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 : Introduction

973
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...

Skin Cancer

6.6K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Area of Science:

  • Ophthalmology
  • Corneal Diseases

Background:

  • Salzmann's nodular degeneration (SND) is a rare, noninflammatory, degenerative corneal condition.
  • Characterized by bluish-gray nodular opacities, typically bilateral and affecting individuals aged 50-60, often with a history of corneal inflammation.

Purpose of the Study:

  • To describe the clinical characteristics, diagnostic methods, and management strategies for Salzmann's nodular degeneration.
  • To evaluate the visual prognosis following treatment for SND.

Main Methods:

  • Review of clinical features, including nodule appearance and location.
  • Diagnostic investigations such as ultrasonic pachymetry, OCT, ultrasound biomicroscopy, and confocal microscopy.
  • Analysis of treatment outcomes for conservative and surgical interventions.

Main Results:

  • Nodules are typically 1-2 mm, bluish-white to gray, and located in Bowman's layer, which is often absent and replaced by abnormal material.
  • Conservative management with topical lubricants is effective for most patients.
  • Surgical options like superficial keratectomy, phototherapeutic keratectomy, and keratoplasty, with modifications, yield optimal visual outcomes with low recurrence rates.

Conclusions:

  • Salzmann's nodular degeneration requires accurate diagnosis through various imaging techniques.
  • Effective management ranges from conservative lubrication to surgical interventions, ensuring a favorable visual prognosis.
