Amyloid Fibrils03:03

Amyloid Fibrils

12.0K
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,...

Mortar Joint Deterioration in Masonry

357
Mortar joint deterioration is a significant concern in masonry structures, with water accumulation in the joints leading to damage from freeze-thaw cycles. The repeated expansion of water during freezing and its melting during thawing develop and propagate cracks in the masonry joints. Eventually, this leads to the spalling of mortar from the joints, loosening masonry units and weakening the structure. The deteriorated mortar joints are also vulnerable to moisture intrusion into the walls.

Cognitive Dissonance01:38

Cognitive Dissonance

37.5K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Fibril-associated Collagen01:11

Fibril-associated Collagen

3.4K
Fibril-associated collagens are a type of collagens present in the extracellular matrix with interrupted triple helices or FACIT (Fibril-associated collagens interrupted triple-helices). FACIT help connect and attach the collagen fibrils with each other as well as with other proteins of the extracellular matrix.
For example, the type II collagen fibrils in cartilage have covalently bound type IX fibril-associated collagens at regular intervals. Other types of fibril-associated collagens are...

Cognition and Behavior01:23

Cognition and Behavior

377
Social psychology examines the complex interplay between individual mental processes and social interactions. Historically, the field was divided into two domains: social behavior and social cognition. Researchers focusing on social behavior analyzed actions within social contexts, such as conformity, aggression, or cooperation. Meanwhile, social cognition researchers investigated how people perceive, interpret, and mentally represent their social environments. However, modern perspectives no...

    Area of Science:

    • Cardiology
    • Neurology
    • Geriatrics

    Background:

    • Growing interest in the association between atrial fibrillation (AF) and cognitive decline/dementia.
    • No definitive cure exists for cognitive decline and dementia, driving research into preventative strategies.
    • The precise causal mechanisms linking AF to cognitive impairment remain incompletely understood.

    Purpose of the Study:

    • To review epidemiologic studies on the association between atrial fibrillation and cognitive function.
    • To explore potential pathophysiological mechanisms underlying this link.
    • To evaluate the impact of atrial fibrillation therapies on cognitive outcomes.

    Main Methods:

    • Systematic review of epidemiologic research.
    • Analysis of proposed pathophysiological pathways.
    • Assessment of evidence regarding therapeutic interventions for atrial fibrillation.

    Main Results:

    • Epidemiologic data suggest a significant association between atrial fibrillation and increased risk of cognitive decline and dementia.
    • Several mechanisms, including cerebral microemboli, hypoperfusion, and inflammation, are implicated.
    • Therapies for atrial fibrillation, such as anticoagulation and catheter ablation, show promise in mitigating cognitive decline.

    Conclusions:

    • Atrial fibrillation is a significant risk factor for cognitive decline and dementia.
    • Understanding the underlying mechanisms is crucial for developing targeted preventative strategies.
    • Current treatments for atrial fibrillation may offer a viable approach to preserving cognitive function.
