Polymer Classification: Crystallinity

3.8K
Unlike ionic or small covalent molecules, polymers do not form crystalline solids due to the diffusion limitations of their long-chain structures. However, polymers contain microscopic crystalline domains separated by amorphous domains.
Crystalline domains are the regions where polymer chains are aligned in an orderly manner and held together in proximity by intermolecular forces. For example, chains in the crystalline domains of polyethylene and nylon are bound together by van der Waals...

Psychodynamic Perspectives on Personality

1.5K
The psychodynamic perspective in psychology asserts that most personality functions operate unconsciously, outside of awareness. This means that the motives and emotions driving behavior often remain hidden, automatically buried in the unconscious mind as a defense mechanism to shield us from psychological distress. According to this theory, the unconscious mind contains thoughts, memories, and emotions that are too disturbing to face directly.
Psychodynamic theorists argue that unconscious...

Satellite Stem Cells and Muscular Dystrophy

2.3K
Satellite stem cells or myosatellite cells are quiescent stem cells that Alexander Mauro first identified in 1961. These cells are located between the sarcolemma, the plasma membrane of muscle fibers, and the basal lamina, the connective tissue sheath covering it. These mononucleated cells are activated in response to muscle injury, can transform into myoblasts, and may form or repair muscle fibers. Myosatellite cells can provide additional myonuclei for muscle regeneration or return to a...

The Behavioral Perspective on Personality

801
Behaviorists view personality as primarily shaped by environmental reinforcements and consequences. According to this perspective, behavior is influenced by external stimuli, and individuals adjust their actions based on rewards and punishments. Over time, learning histories — accumulated patterns of reinforcement — play a significant role in shaping personality. Behaviors that lead to positive outcomes are reinforced, while those resulting in negative outcomes are diminished.

Criticisms of the Evolutionary Perspective

345
In a study where individuals posing as strangers offered compliments and proposed casual sex to students, the responses differed significantly based on gender. Not a single woman accepted the proposal, while 70% of the men agreed. This outcome provides a useful scenario to explore through the lens of evolutionary psychology and social learning theory, highlighting the diverse perspectives on human sexual behaviors.
Evolutionary psychology provides one explanation for these findings, suggesting...

Social Cognitive Perspective on Personality01:30

Social Cognitive Perspective on Personality

993
Social cognitive perspectives on personality emphasize the importance of conscious awareness, beliefs, expectations, and goals in shaping behavior. These perspectives incorporate behaviorist principles, such as learning through reinforcement and conditioning, but extend beyond them by highlighting human reasoning and planning. Unlike traditional behaviorist views, social cognitive theory focuses on how individuals reflect on their past experiences and plan for future outcomes by considering...

Area of Science:

  • Ophthalmology
  • Genetics
  • Metabolic Disorders

Background:

  • Bietti crystalline dystrophy (BCD) is a rare inherited retinal disease.
  • It stems from mutations in the CYP4V2 gene, affecting lipid metabolism.
  • Clinical hallmarks include retinal deposits, pigment epithelium atrophy, and corneal limbal glittering dots.

Purpose of the Study:

  • To provide updated insights into the clinical and molecular characteristics of BCD.
  • To review the underlying mechanisms, genetic diagnosis, and epigenetic factors.
  • To discuss exploration techniques and novel therapeutic developments for BCD.

Main Methods:

  • Literature review of clinical and molecular studies on Bietti crystalline dystrophy.
  • Analysis of genetic and epigenetic factors contributing to BCD.
  • Evaluation of diagnostic techniques and emerging therapeutic strategies.

Main Results:

  • BCD is linked to CYP4V2 gene mutations, impacting lipid metabolism and n-3 polyunsaturated fatty acid synthesis.
  • Diagnostic advancements include genetic testing and imaging techniques.
  • Progress is being made in identifying genetic/epigenetic factors and developing targeted therapies.

Conclusions:

  • Accurate diagnosis and prognosis of BCD are improving with updated clinical and molecular insights.
  • Understanding the metabolic basis aids in developing novel therapeutic interventions.
  • This review empowers clinicians with information for better patient management and prediction of disease course.
