Sleep Apnea
483
Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.

Other Pulmonary Disorders

Respiratory disorders encompass a range of conditions with varying levels of severity. Asthma, marked by chronic airway inflammation and hypersensitivity, is one such condition. It can lead to airway obstruction due to factors like bronchial spasms, mucosal edema, increased mucus secretion, or epithelial damage. Asthma triggers are diverse, ranging from allergens to emotional upset, and treatment focuses on both immediate relief through bronchodilators and long-term inflammation suppression.

Genome-wide Association Studies-GWAS
15.3K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.

Pulmonary Hypertension: Classification and Pathogenesis
580
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...
