Self-Concept

1.7K
Self-concept is the cognitive and emotional understanding individuals hold about their identity. It evolves through various developmental stages, beginning in infancy and maturing as children grow. This concept influences how individuals perceive their abilities, interact with others, and manage challenges throughout life.
Infancy and Emerging Recognition
During infancy, self-concept is virtually nonexistent. Babies do not distinguish themselves as separate entities and often mistake their...

Concepts and Prototypes

The human nervous system handles vast amounts of information by translating sensory stimuli into neural impulses, which the brain processes, creating thoughts expressed through language or stored as memories. The brain also synthesizes information from emotions and memories, which significantly influence thoughts and behaviors. This intricate process creates a comprehensive mental picture.
The brain organizes this information using concepts, which are mental categories grouping linguistic data,...

Pulmonary Hypertension: Classification and Pathogenesis

659
Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

Basic Concept

6.2K
Engineering mechanics is a branch of engineering that studies motion and the forces acting on objects. It is a fundamental subject and forms the basis of many other engineering disciplines. Length, time, mass, and force are some basic concepts in engineering mechanics.
Length, which measures the distance traveled by an object, is a fundamental concept in engineering mechanics. We use coordinates relative to a reference point to describe the distance. Length not only helps to describe the...

Area of Science:

  • Dermatology
  • Immunology
  • Biochemistry

Background:

  • Acne vulgaris is a common skin condition characterized by pilosebaceous unit inflammation.
  • Key factors in acne pathogenesis include hormonal influences (insulin, IGF-1, androgens), Propionibacterium acnes, and altered lipid metabolism.

Purpose of the Study:

  • To elucidate the inflammatory pathways involved in acne pathogenesis.
  • To explore how insights into these pathways can inform novel therapeutic strategies.

Main Methods:

  • Review of current literature on acne pathogenesis.
  • Analysis of the roles of hormones, microbial factors, and lipid profiles.
  • Examination of innate and adaptive immune responses, including toll-like receptors and inflammasome activation.

Main Results:

  • Hormones, Propionibacterium acnes, and a proinflammatory lipid profile are pivotal in acne development.
  • Innate immune responses are initiated via toll-like receptors and inflammasome activation.
  • Adaptive immune responses follow, contributing to the inflammatory cycle.

Conclusions:

  • Acne pathogenesis is a complex interplay of hormonal, microbial, and lipid-driven inflammation.
  • Understanding these specific inflammatory mechanisms provides a foundation for developing targeted acne therapies.
