Additionally, it provides a mechanistic explanation for the observed curve through the differences in GI-tract passage rate.
The GI-tract passage rate in this subject was influenced by co-administration of drugs that stimulate or delay gastric emptying.
The only useful method is the total GI tract transit time measured using a tracer passage.
The GI Slide, for example, is a giant model of the digestive tract with passages to slide and crawl through, culminating at the inevitable end; the Tour du Nose is a walk-through sinus passage complete with hairs and breezy sneezes.
The vocal tract comprises the passage from the trachea (windpipe) to the orifices of the mouth and nose; all the organs used in speaking lie in this passage.
Meningococci colonize the nasopharynx and may penetrate the mucosal barrier of the upper respiratory tract by transcellular passage of epithelial cells [ 19].
In our case, no history of urinary tract infection and passage of fungal masses per urethra prior to ICPL and instrumentation suggest that the Aspergillus was introduced into the urinary tract during ureteroscopy and placement of stent in the ureter.
25 Another possible mechanism of protection is pre-exposure of the infant to ARV agents that can cross the placenta which may protect the infant from exposure to a maternal genital tract virus during passage through the birth canal.
Possible post-copulatory explanations include second-male sperm being flushed at a higher rate from the reproductive tract by egg passage, or, a higher rate of ejaculate ejection of second-male sperm - as observed in hermaphrodite-male sperm competition, such that hermaphrodites are more likely to eject male sperm when self-sperm are present [ 17].
26 In addition, postexposure prophylaxis provided through drug administration to the infant after birth would protect against a cell-free or cell-associated virus that might have entered the fetal/infant system during labor through maternal-fetal transfusion during uterine contractions or by the infant swallowing genital tract secretions during passage through the birth canal.
Both compounds are natural decongestants and histamine reducers that have direct, positive benefits on the respiratory tract and nasal passage airflow.
