Metascience (also known as meta-research) is the use of scientific methodology to study science itself. Metascience seeks to increase the quality of scientific research while reducing inefficiency . It is also known as "research on research" and "the science of science", as it uses research methods to study how research is done and ...
Bronchoalveolar lavage. Bronchoalveolar lavage ( BAL ), also known as bronchoalveolar washing, is a diagnostic method of the lower respiratory system in which a bronchoscope is passed through the mouth or nose into an appropriate airway in the lungs, with a measured amount of fluid introduced and then collected for examination. This method is ...

Difficulty breathing, a cardinal symptom of left ventricular failure, may manifest with progressively increasing severity as the following:[citation needed] 1. Difficulty breathing with physical activity (exertional dyspnea) 2. Difficulty breathing while lying flat (orthopnea) 3. Episodes of waking up from sleep gasping for air (paroxysmal nocturna...
Flash Pulmonary Edema or Crash Pulmonary Edema is a clinical characterization of acute heart failure with a dramatic presentation. It is an acute cardiac disease precipitated by cardiac events and usually associated with severe hypertension.
Chronic stable heart failure may easily decompensate. This most commonly results from an intercurrent illness (such as pneumonia), myocardial infarction (a heart attack), abnormal heart rhythms (such as atrial fibrillation), uncontrolled high blood pressure, or the person's failure to maintain a fluid restriction, diet, or medication. Other well re...
In acute decompensated heart failure, the immediate goal is to re-establish adequate perfusion and oxygen delivery to end organs. This entails ensuring that airway, breathing, and circulation are adequate. Management consists of propping up the head of the patient, giving oxygen to correct hypoxemia, administering morphine, diuretics like furosemid...
t. e. Anaplasia (from Ancient Greek: ἀνά ana, "backward" + πλάσις plasis, "formation") is a condition of cells with poor cellular differentiation, losing the morphological characteristics of mature cells and their orientation with respect to each other and to endothelial cells. The term also refers to a group of morphological changes ...
t. e. Metamagnetism is a sudden (often, dramatic) increase in the magnetization of a material with a small change in an externally applied magnetic field. The metamagnetic behavior may have quite different physical causes for different types of metamagnets. Some examples of physical mechanisms leading to metamagnetic behavior are:
PubMed. PubMed is a free database including primarily the MEDLINE database of references and abstracts on life sciences and biomedical topics. The United States National Library of Medicine (NLM) at the National Institutes of Health maintains the database as part of the Entrez system of information retrieval.
Common sites for squamous metaplasia include the bladder and cervix. Smokers often exhibit squamous metaplasia in the linings of their airways. These changes don't signify a specific disease, but rather usually represent the body's response to stress or irritation. Vitamin A deficiency or overdose can also lead to squamous metaplasia.
