Infant respiratory distress syndrome (IRDS), also known as surfactant deficiency disorder (SDD), [2] and previously called hyaline membrane disease (HMD), is a syndrome in premature infants caused by developmental insufficiency of pulmonary surfactant production and structural immaturity in the lungs.
The clinical syndrome is associated with pathological findings including pneumonia, eosinophilic pneumonia, cryptogenic organizing pneumonia, acute fibrinous organizing pneumonia, and diffuse alveolar damage (DAD). Of these, the pathology most commonly associated with ARDS is DAD, which is characterized by a diffuse inflammation of lung tissue.
N.E.R.D.S. is a children's pentalogy written by Michael Buckley and illustrated by Ethen Beavers.The series tells the story of a fictional spy agency and its agents—children who have their "nerdy" characteristics upgraded into a tool that they can use to fight crime.
The cause is not fully understood, but evidence suggests that raised oxygen levels at the lens may be caused by deterioration of the vitreous humour due to age, and this causes degradation of lens crystallins by cross-linking, forming aggregates capable of scattering light. This may be an end-state development of the more commonly observed ...
Degenerative disease is the result of a continuous process based on degenerative cell changes, affecting tissues or organs, which will increasingly deteriorate over time. [1] In neurodegenerative diseases, cells of the central nervous system stop working or die via neurodegeneration. An example of this is Alzheimer's disease. [2]
Chronic obstructive pulmonary disease (COPD) is a type of progressive lung disease characterized by chronic respiratory symptoms and airflow limitation. [8] GOLD 2024 defined COPD as a heterogeneous lung condition characterized by chronic respiratory symptoms (dyspnea or shortness of breath, cough, sputum production and/or exacerbations) due to abnormalities of the airways (bronchitis ...
It also causes emulsified sauces, such as hollandaise, to "break" ("split"). Additionally, it creates unsightly moisture pockets within baked custard dishes, such as flan or crème brûlée . Gels formed from agarose are prone to syneresis, and the degree of syneresis is inversely proportional to the concentration of the agarose in the gels.
Overview of signal transduction pathways involved in apoptosis. Cell death is the event of a biological cell ceasing to carry out its functions. This may be the result of the natural process of old cells dying and being replaced by new ones, as in programmed cell death, or may result from factors such as diseases, localized injury, or the death of the organism of which the cells are part.
