Entomological correspondence of Thaddeus William Harris, M. D

Abstract

Of other genuine naturalists I have read, but he is the only one I ever knew." This is hardly too strong a statement of the loyalty entertained toward this eminent man by those who had the privilege of being his pupils in Natural History. In him there lived for us the very spirit of Linnaeus, or whatever name best represents the simplest and purest type of the naturalist. The personal attachment thus won, the healthy influence thus exerted, and the slow and gradual recognition of the merit of his methods, are a form of success more congenial to the temperament of Dr.Harris than would have been any more immediate and superficial applauses.Xll MEMOIR.

Collagens XV and XVIII show different expression and localisation in cutaneous squamous cell carcinoma: type XV appears in tumor stroma, while XVIII becomes upregulated in tumor cells and lost from microvessels

“…Our results suggest that interstitial collagen XV might be expressed by cancer-associated fibroblasts or macrophages. Stromal deposits of collagen XV have previously been reported in human colon and breast carcinomas as well as human cervical carcinoma xenografts (7,8,12). Interestingly, deposition of collagen XV in the tumor ECM has been associated with the suppression of tumorigenicity in human cervical carcinoma cells (12), and with decreased invasion of pancreatic adenocarcinoma cells (13).…”

“…In addition, collagen XV appears in the interstitium of invasive breast carcinoma (8) and colon adenocarcinoma (7). Collagen XV has also been suggested to act as a tumor suppressor (11), which is supported by the observations that a high collagen XV level alters the growth properties of human cervical carcinoma cells and suppresses their tumorigenicity in mice (12), and reduces the invasion of pancreatic adenocarcinoma cells in vitro (13). Moreover, the inactivation of collagen XV by promoter hypermethylation has been observed in human renal cell carcinomas (14).…”

“…Moreover, the inactivation of collagen XV by promoter hypermethylation has been observed in human renal cell carcinomas (14). Finally, the endostatin domain of collagen XVIII and the corresponding restin domain in collagen XV inhibits endothelial cell migration, angiogenesis and tumor growth in various experimental models in some studies (15)(16)(17)(18), while in others angiogenesis was not affected (12,19). The overexpression of endostatin in mouse skin reduces tumor inflammation and lymphangiogenesis in the chemical skin carcinogenesis model (19).…”

“If we can just ‘stall’ new unfriendly legislations, the scoreboard is already in our favour”: transnational tobacco companies and ingredients disclosure in Thailand

“…59 Some were sceptical as to the chances of the T&N approach being influential, 60 with Don Harris of PM's Hong Kong office noting in October 1991 that ''under the circumstances it seems increasingly unlikely''. 61 A list of ingredients by company was promoted as sufficiently rigorous to satisfy regulatory demands in Europe, suggesting that ''there would be considerable financial savings and administrative efficiency if a government were to embrace these internationally recognised lists''. 27 Harris described PM's strategy as aiming ''to have the public disclosure provision removed form the Bill, to have the issue dealt with as regulations rather than law'' and to have the Thai government accept one of the lists used in Europe.…”

Soil Stress Measurement: Part I. Transducer in a Uniform Stress Field

“…The transducers can be used to measure a stress in any orientation, but in compaction research they are commonly used to measure vertical stresses, so they shall be referred to as vertical transducers.
