Autophagic Cell Death01:18

Autophagic Cell Death

4.6K
Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.
Autophagy and Apoptosis
Autophagy can activate apoptosis. In normal conditions, the autophagy activating protein Beclin-1 and...

Overview of Cell Death

10.2K
Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...

Negative Regulator Molecules01:23

Negative Regulator Molecules

Positive regulators allow a cell to advance through cell cycle checkpoints. Negative regulators have an equally important role as they terminate a cell’s progression through the cell cycle—or pause it—until the cell meets specific criteria.

Adult Stem Cells01:33

Adult Stem Cells

33.9K
Stem cells are undifferentiated cells that divide and produce more stem cells or progenitor cells that differentiate into mature, specialized cell types. All the cells in the body are generated from stem cells in the early embryo, but small populations of stem cells are also present in many adult tissues including the bone marrow, brain, skin, and gut. These adult stem cells typically produce the various cell types found in that tissue—to replace cells that are damaged or to continuously...

Fixing Double-strand Breaks02:04

Fixing Double-strand Breaks

14.9K
The double-stranded structure of DNA has two major advantages. First, it serves as a safe repository of genetic information where one strand serves as the back-up in case the other strand is damaged. Second, the double-helical structure can be wrapped around proteins called histones to form nucleosomes, which can then be tightly wound to form chromosomes. This way, DNA chains up to 2 inches long can be contained within microscopic structures in a cell. A double-stranded break not only damages...

Area of Science:

  • Neurology
  • Critical Care Medicine
  • Forensic Pathology

Background:

  • Brain death determination is a critical clinical and legal practice.
  • Concerns exist regarding the accuracy and implications of brain death diagnosis.
  • Post-cardiac arrest hypoxic ischemic encephalopathy (CA-HIE) presents unique diagnostic challenges.

Observation:

  • A case study highlighted a patient meeting brain death criteria but later showing signs inconsistent with death after continued support.
  • This patient experienced CA-HIE following cardiac arrest.
  • Variable clinical outcomes are observed in severe CA-HIE cases.

Findings:

  • The accuracy of brain death diagnosis in CA-HIE requires careful consideration.
  • Pathophysiological correlations between CA-HIE and brain death criteria are complex.
  • Ancillary testing and clinical criteria may yield ambiguous results in some CA-HIE scenarios.

Implications:

  • This case raises significant clinical, ethical, and legal questions about brain death determination.
  • Recommendations are needed for managing goals of care and interventions in CA-HIE.
  • Palliative care consultations are crucial for navigating complex end-of-life decisions in these cases.
