“…In general, however, it is only between cases showing a well-marked cellular reaction and those in whom such a reaction is virtually absent that a real difference in prognosis has been shown. Berg (1962) considered that the significant stromal cell in host defence against anaplastic breast cancer of "no special type" was the plasma cell. On the other hand, Schiodt (1966), and also Richardson (1956), found no correlation between prognosis and differing proportions of lymphocytes and plasma cells.…”

“…MacCarty (1922) was one of the first to correlate stromal factors in malignant disease with survival, but this work attracted little attention, especially as a possible guide to host defence. More recently several workers have rekindled interest in the presence of round-cell infiltration in breast cancer which they have been able to correlate with prognosis (Black et al, 1955;Black and Speer, 1958;Berg, 1962;Cutler et al, 1963;Hamlin, 1968). …”

This paper deals with a special type of mammary carcinoma, generally of high-grade malignancy, which carries a remarkably good prognosis-the so-called "medullary carcinoma of the breast with lymphoid infiltrate." Probably the increased lymphoid tissue seen in these tumours is concerned with cell-mediated and humoral immunological reactions and reflects a strong host-defence mechanism which is responsible for the remarkably high survival rates following radical treatment. Since the evidence for host resistance to malignant disease is based largely on animal data, the opportunity to study a group of patients followed for 20 years, in whom this type of defence reaction appears to exist, is of considerable clinical interest.Among 1,411 cases of breast cancer there were 104 with medullary carcinoma (7.4%), for which the corrected 5- to 20-year survival rates have been calculated. After 20 years 74% of cases with operable medullary tumours were alive, compared with 14% of cases with similar stage non-medullary cancer. In the presence of histologically proved axillary metastases the 20-year survival rate was 61% for medullary cases, compared with only 13% for other types of breast cancer.In 30 cases of medullary cancer in which the axilla was free, the corrected 20-year survival rate was 95% following a combination of radical operation and radiotherapy. No evidence could be found that axillary dissection or postoperative irradiation is harmful to women with operable highly malignant breast cancer in whom a well-marked host resistance is thought to be present. A combination of radical mastectomy and postoperative irradiation appears to be the most effective treatment for such cases. The present grounds for rejecting a radical approach to treatment of breast cancer, based on current immunological considerations, are regarded as being quite inadequate.

“…Recently,s upramolecular polymers have also been fabricated by interfacial polymerization of the two precursors in two immiscible solvents,t hereby providing af acile strategy for supramolecular materials with controllable properties,structures,and functions. [37] Coordination polymers,w hich consist of metal ions and organic ligands linked through coordination bonds,appeared in the early 1960s, [38] and the term "coordination polymer" was defined by Bailar in 1964. [39] Acoordination polymer with reversible coordination bonds can also be assigned as as upramolecular polymer.…”

Interfacial Polymerization: From Chemistry to Functional Materials

Interfacial polymerization, where a chemical reaction is confined at the liquid–liquid or liquid–air interface, exhibits a strong advantage for the controllable fabrication of films, capsules, and fibers for use as separation membranes and electrode materials. Recent developments in technology and polymer chemistry have brought new vigor to interfacial polymerization. Here, we consider the history of interfacial polymerization in terms of the polymerization types: interfacial polycondensation, interfacial polyaddition, interfacial oxidative polymerization, interfacial polycoordination, interfacial supramolecular polymerization, and some others. The accordingly emerging functional materials are highlighted, as well as the challenges and opportunities brought by new technologies for interfacial polymerization. Interfacial polymerization will no doubt keep on developing and producing a series of fascinating functional materials.

“…Seit kurzem werden supramolekulare Polymere auch durch Grenzflächenpolymerisation von zwei Precursoren in zwei nicht mischbaren Lçsungsmitteln hergestellt, was eine einfache Herstellung von supramolekularen Materialien mit kontrollierbaren Eigenschaften, Strukturen und Funktionen ermçglicht. [37] Koordinationspolymere aus Metallionen und organischen Liganden, mittels koordinativer Bindungen gebildet, traten in den frühen 1960er Jahren in Erscheinung, [38] und der Begriff "Koordinationspolymer" wurde 1964 von J. C. Bailar definiert. [39] Koordinationspolymere mit reversiblen koordinativen Bindungen kçnnen auch den supramolekularen Polymeren zugeordnet werden.…”
