Pulmonary Hypertension: Classification and Pathogenesis

644
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...

Asthma: Pathogenesis and Management

1.3K
Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Cystic Fibrosis: Pathogenesis

871
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

COPD: Pathogenesis and Clinical Features

1.8K
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Multiple Regression

4.0K
Multiple regression assesses a linear relationship between one response or dependent variable and two or more independent variables. It has many practical applications.
Farmers can use multiple regression to determine the crop yield based on more than one factor, such as water availability, fertilizer, soil properties, etc. Here, the crop yield is the response or dependent variable as it depends on the other independent variables. The analysis requires the construction of a scatter plot...

Area of Science:

  • Hematologic Malignancies
  • Cancer Biology
  • Immunology

Background:

  • Multiple myeloma (MM) is a plasma cell malignancy causing bone marrow infiltration, anemia, and bone lesions.
  • Despite survival improvements, MM often becomes refractory and remains incurable for most patients.

Purpose of the Study:

  • To describe MM progression stages and present current insights into its pathogenesis.
  • To discuss foundational concepts and recent scientific findings in MM research.

Main Methods:

  • Review of basic conceptual works.
  • Analysis of recent scientific publications.

Main Results:

  • MM pathogenesis involves genetic predisposition, inflammation, and immune response, initiating during B cell maturation.
  • Disease progression includes monoclonal gammopathy of undetermined significance, asymptomatic myeloma, and symptomatic MM.
  • MM exhibits spatial clonal heterogeneity, with aggressive clones in focal lesions often showing tumor suppressor gene inactivation (e.g., TP53), driving treatment resistance.

Conclusions:

  • Tumor biology dictates MM progression and treatment response variability.
  • Understanding clonal heterogeneity and genetic factors is crucial for overcoming treatment resistance in refractory MM.
