Pulmonary embolism; A lung illustration depicting a pulmonary embolism as a thrombus (blood clot) that has travelled from another region of the body, causes occlusion of the pulmonary bronchial artery, leading to arterial thrombosis of the superior and inferior lobes in the left lung: Specialty: Hematology, cardiology, pulmonology, Emergency ...
Pulmonary embolism is the third leading cause of death from cardiovascular disease and happens when blood clots block an artery in the lungs, so blood and gas cannot flow normally.
Levels of DHEA-S in circulation are approximately 250 to 300 times those of DHEA. [20] DHEA-S in turn can be converted back into DHEA in peripheral tissues via steroid sulfatase (STS). [54] [55] The terminal half-life of DHEA is short at only 15 to 30 minutes. [56] In contrast, the terminal half-life of DHEA-S is far longer, at 7 to 10 hours. [56]
Blood clots in veins don't typically cause strokes, but they can lead to deep vein thrombosis, aka the reason you should stretch your legs during a long flight. Clots that form in the deep veins ...
7α-Hydroxydehydroepiandrosterone (7α-hydroxy-DHEA; 7α-OH-DHEA), also known as 3β,7α-dihydroxyandrost-5-ene-17-one, is an endogenous, naturally occurring steroid and a major metabolite of dehydroepiandrosterone (DHEA) that is formed by CYP7B1 (steroid 7α-hydroxylase) in tissues such as the prostate gland and by CYP3A4 in the liver.
Venous thrombosis can lead to pulmonary embolism when the migrated embolus becomes lodged in the lung. In people with a "shunt" (a connection between the pulmonary and systemic circulation), either in the heart or in the lung, a venous clot can also end up in the arteries and cause arterial embolism.

Dehydroepiandrosterone sulfate, abbreviated as DHEA sulfate or DHEA-S, also known as androstenolone sulfate, is an endogenous androstane steroid that is produced by the adrenal cortex. [1] It is the 3β- sulfate ester and a metabolite of dehydroepiandrosterone (DHEA) and circulates in far greater relative concentrations than DHEA. [ 2 ]
Infant prematurity is the factor most commonly associated with pulmonary hemorrhage. Other associated factors are those that predisposed to perinatal asphyxia or bleeding disorders, including toxemia of pregnancy, maternal cocaine use, erythroblastosis fetalis, breech delivery, hypothermia, infection (like pulmonary tuberculosis), Infant respiratory distress syndrome (IRDS), administration of ...
