In humans, ostiomeatal obstruction is a key precipitating factor in the pathogenesis of sinusitis.
Fragmentation problems are particularly severe in freshwater systems [ 8], where the one-dimensional structure of river systems causes dams, weirs and other human-made obstructions to represent impassable barriers to many fishes and invertebrates.
But he cautions that the study may not translate fully to humans, because partial obstruction is just one of the causes of overactive bladder.
With 14 million Americans out of work and 46 million living in poverty, the real human cost of more obstruction and inaction is undeniable and inexcusable.
Together, the medicolegal defence linked with this philosophy to proffer subluxation as an obstruction to human health [ 18] (p. 66 67).
The most extreme unorthodox view relative to current scientific paradigms associated with health care was defined by a subgroup who identified themselves with the notion that the chiropractic subluxation (lesion treated) was an "obstruction to human health".
McGregor-Triano [ 3] found 17.2% of 64 chiropractors from around the world, responding to a survey at a chiropractic conference, could be identified as belonging to the subgroup of practitioners for whom subluxation was considered an obstruction to human health.
Given the fact that similar changes are observed in 99mTc-MAG3 renogram in human patients with renal obstruction [ 26, 27], combination of this imaging technique with mouse UUO models should provide an effective assay for evaluating treatment protocols of this disease or screening new pharmacological agents as well as for elucidating pathophysiological mechanisms of obstructive kidney disease.
Our mouse genetic model may resemble features of human chronic intestinal pseudo-obstruction.
Under the category of risks, the chapter considers fire and explosion, extreme environmental condition, human element, traffic and obstructions, and operational hazards.
