Modeling in Therapy

218
Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.

Parkinson's Disease: Overview

1.1K
Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...

Cross-bridge Cycle01:26

Cross-bridge Cycle

120.2K
As muscle contracts, the overlap between the thin and thick filaments increases, decreasing the length of the sarcomere—the contractile unit of the muscle—using energy in the form of ATP. At the molecular level, this is a cyclic, multistep process that involves binding and hydrolysis of ATP, and movement of actin by myosin.

Amyloid Fibrils03:03

Amyloid Fibrils

11.0K
Amyloid fibrils are aggregates of misfolded proteins.  Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils. 
Amyloid deposits were observed as early as 1639 in the liver and the spleen.   In 1854, Rudolph Virchow performed iodine staining,...

Area of Science:

  • Neuroscience
  • Genetics
  • Pathology

Background:

  • Amyotrophic lateral sclerosis (ALS) is a complex neurodegenerative and neuroinflammatory disease.
  • ALS is characterized by its heterogeneous clinical presentation, being multigenic, multifactorial, and non-cell autonomous.

Purpose of the Study:

  • To provide a comprehensive review of various in vivo models used in amyotrophic lateral sclerosis (ALS) research.
  • To analyze how different eukaryotic organisms help dissect the pathological pathways of ALS insurgence and progression.

Main Methods:

  • Review of existing literature on in vivo models for ALS research.
  • Comparative analysis of vertebrate and invertebrate models including yeast, worms, flies, zebrafish, mice, rats, guinea pigs, dogs, and non-human primates.

Main Results:

  • Various organisms reproduce key clinical features of ALS, aiding in disease mechanism dissection.
  • Commonalities and discrepancies among models are identified, offering insights into ALS pathology.
  • Emerging roles of experimental organisms in advancing ALS research are highlighted.

Conclusions:

  • Concurrent and comparative analysis of diverse ALS models is essential for understanding disease causes and mechanisms.
  • Harnessing these models presents challenges but is vital for developing efficacious ALS therapeutics.
