Gastrointestinal and hepatic mechanisms limiting entry and dissemination of lipopolysaccharide into the systemic circulation
sup] However, it may cause potential and inevitable injuries to other organs, such as the brain and kidneys, because the remaining microspheres in the left ventricle go into the systemic circulation
with blood flow after opening the aorta.
Since the drug is given as one drop in each eye every waking hour, transfer to the systemic circulation
should be expected, but the amount, if it occurs, has not been reported.
The thought process was that if the patient had PFO or a septal defect, there would be a venue through which an adult worm in the right ventricle could be embolized and enter both the pulmonary circulation and the systemic circulation
to end up in the spleen.
1) D-transposition (d-TGA) is a cyanotic lesion characterized by inappropriate ventriculoarterial connections leading to parallel pulmonary and systemic circulations
that is best surgically corrected very early in life.
Although the general arrangement of blood vessels in both circulations is from arteries to capillaries to veins, in some parts of the systemic circulation
it is modified so that a vein or an arteriole is interposed between two capillary networks; these vessels constitute portal systems.
In summary, we suggest the following potential cellular mechanisms: (1) administration of EMPB attracts MSCs from the bone marrow or perivascular region into systemic circulation
; (2) topical application of EMPB further directs the homing of MSCs from systemic circulation
to the wound region; (3) mobilized MSCs proliferate and secrete various cytokines having proregenerative activities; and (4) cytokines activate skin cell types and consequently the activated skin cells, the differentiated cells from MSCs may thus remodel wounded tissues.
Particulate matter (PM) has been consistently associated with cardiovascular disease development and progression, (1,2) and is believed to contribute to development either indirectly through the autonomic nervous system or inflammatory responses, or directly via entry into systemic circulation
and subsequent damage to blood vessels.
The inhaled nano-sized particles can penetrate deeply into the respiratory tract, pass into the systemic circulation
and reach various organs," added the professor.
Pulmonary sequestration is an embryonic malformation forming a nonfunctional cystic lung tissue which is not connected to the normal tracheobronchial tree and receives its blood supply aberrently from systemic circulation
Upon deployment, the Watchman excludes the left atrial appendage from the systemic circulation
Ultrasound of the abdomen usually reveals abnormal cystic or tubular, anechoic, serpiginous vascular structures communicating between portal venous structures and the systemic circulation
