Minute volume refers to the total volume of gases that a person inhales and exhales in a single minute. This is often a measure used to determine the function of external respiratory devices as well as a measure of general lung volume and lung...
As a quantitative tool, it offers the ability to determine what percentage of the lung is involved with the disease and to break this down into areas of ground glass density, consolidation, collapse, etc. This can be evaluated on serial studies which may be predictive of a patient’s ...
The hallmark concern for the body living at high altitude is low oxygen. We breathe in less, and thus less is sent throughout our blood stream to our tissues. We are quick to think about how this affects our heart and lungs, but what about our kidneys? What are our kidneys even respon...
The gastrointestinal tract is a major site of HIV replication, independent of the way of acquisition of the virus[43]. Gut-associatedlymphoid tissue(GALT) is where the majority of CD4+T lymphocytes are housed[44,45]. These lymphocytes, in contrast to what happens inperipheral blood monon...
Antifibrinolytic agents (choice B) prevent normal fibrin degradation. For example, tranexamic acid is an antifibrinolytic indicated for massive bleeding from trauma but is not needed for mild or moderate bleeding patients. Septic Shock Patient w/ abdominal mass: he goals of initial treatment in sept...
Explain what factors can influence how well oxygen and carbon dioxide are exchanged at the respiratory membrane.Anatomy of the lung helps respiratory exchange:The respiratory membrane is the membrane where oxygen can diffuse into the bloodstream and carbon dio...
Some environmentalists doubt the energy alternative is ultimately carbon neutral. The Southern Environmental Law Center fears the credits could be the incentive needed for the U.S. to join Europe in scaling up the burning of pellets. “The threat here is ...
Asked about Taliban assurances of safe passage to the airport she said: “So far, I can say that what we need is being granted; the danger comes more from these uncontrollable crowds of people.” As the airlift continues, the U.S. government asked for 18 aircraft from American commercial...
Further investigation is needed to elucidate the impact of spike protein on the brain and its association with other neurological diseases. Our data also suggest a mechanism for the virus’s entry into the central nervous system. In both mouse and COVID-19 human tissues, we found spike protein...
From the perspective of cancer biology, while there is little doubt that oncometabolites play a major role in the late phases of the natural history of cancer, corresponding to what is generally called cancer “progression”, one unresolved question is whether they induce advantage-conferring events...
