Reported here are two cases of a modified Appleby operation for borderline resectable ductal adenocarcinoma of the pancreatic body, in one of which a R0 distal resection was attended to by excision, not only of the celiac axis, but also of the common and left hepatic arteries in the presence of arterial anatomic variation Michels, type Ⅷb. The possibility and avenues of the maintenance of the blood supply to the left hepatic lobe after surgical aggression of this kind are demonstrated employing computed tomography (CT) and 3-D CT angiography. Furthermore, both cases highlight all important worrisome aspects of pancreatic cancer resectability prediction.
The standard of the organization directed on increase of efficiency and quality of monitoring procedure of emissions of harmful substances of the fulfilled gases of diesels of the capital repaired tractors and self-propelled farm vehicles which are in operation, intended for work and working in the conditions of unlimited and limited air exchange is developed — and establishes norms of emissions of harmful substances with the fulfilled gases, means of their definition, at control and bench tests of tractors and the agricultural cars. Technical characteristics of the fuel and engine oil intended for test of the diesel are defined. Modern control devices are optimized and techniques of tool control of the maintenance of CO, CH and NOx in the fulfilled gases of diesels of page are the agricultural cars.
Рак поджелудочной железы, гисто-логически представленный в 75-85% слу-чаев протоковой аденокарциномой (ПАК ПЖ), является одной из самых злокаче-ственных опухолей пищеварительного тракта [3]. В 2010 году заболеваемость раком поджелудочной железы в общей структуре онкологической заболеваемо-сти в России составила 12% [1], в запад-ных странах этот показатель в среднем равен 13% [8]. Среди прогностических факторов ПАК ПЖ особо значимые сле-дующие: стадия опухоли, радикальность проведенной операции [2,7,13], степень злокачественности (grade) -показатель, основанный на оценке морфологических характеристик опухоли, таких как степень ядерного полиморфизма, количество ми-тозов в 10 репрезентативных полях зрения (РПЗ), содержание муцина в цитоплазме опухолевых клеток [10]. В последние го-ды уделяется немало внимания биологи-ческим характеристикам опухоли -пока-зателям пролиферации и апоптоза [12], мутациям различных регуляторных генов [11]. Следует отметить, что выявление молекулярных изменений является доро-гостоящим методом, поэтому поиск про-
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
