Pollard and Heron pointed out the implications of this issue in 1996: "most kiln sources are characterized by at best a hundred analyses, probably covering a range of "qualities" of vessels produced, a range of vessel types, and, possibly, a time span of tens or even hundreds of years.
Surgical renal denervation should not be attempted in patients for whom renal autotransplantation is being considered as dense scarring related to the procedure might affect the quality and quantity of vessels harvested for the autotransplantation [ 53].
Although increased tumor angiogenesis provides more vessels for potential trafficking of CAR T cells, the quality of the vessels is typically poor, and T cells are unable to efficiently infiltrate tumors, possibly because of vascular endothelial growth factor (VEGF) expression [ 60].

"The causes for the alarming increase in deaths this year are multiple but appear to be related to the declining quality of the vessels used by people-smugglers, the vagaries of the weather and the tactics used by smugglers to avoid detection by the authorities.
This identification allows the examiner to perform angle-corrected and sample volume-adjusted determinations, resulting in an increase in the number [10] and quality of the vessels studied [11].
This calcification is of itself useful information to the surgeon as regards the quality of the vessels for clamping and anastomosis, although there is anecdotal evidence that it may unnecessarily dissuade surgeons from operating and blooming artefacts can certainly make calcified plaques appear much more pronounced than in physical reality.
In the calf station image quality of many vessels segments were assessed as non-excellent, mainly due to venous enhancement and delayed flow due to filling over collateral vessels.
Its author, cruise expert Douglas Ward, has focused his critical eyes on 280 riverships, awarding points out of 100 in five categories: the condition and quality of the vessel, accommodation, cuisine, service and "miscellaneous" covering such topics as accuracy of brochure and standard of entertainment.
