Print-on-demand uses digital printing to produce as few as one or two books (or other documents) at a time. Although the cost per item is higher than it might be with larger runs, it is more cost-effective than offset or other plate-based printing methods when doing small runs.
It is not known exactly how Imuran works to prevent kidney transplant rejection or to treat rheumatoid arthritis. Imuran acts in a way similar to certain types of chemotherapy medications, killing cells by damaging DNA. Also, much like chemotherapy medications, Imuran suppresses the immune system (it is thought that the medication works mostly by suppressing the immune system). The immune system is responsible for rejecting transplanted organs, and an overactive immune system plays an important role in rheumatoid arthritis.
In many cases, chemotherapy medicines are given in combination, which means you get two or three different medicines at the same time. These combinations are known as chemotherapy regimens. In early stage breast cancer, standard chemotherapy regimens lower the risk of the cancer coming back. In advanced breast cancer, chemotherapy regimens make the cancer shrink or disappear in about 30-60% of people treated. Keep in mind that every cancer responds differently to chemotherapy. Standard chemotherapy regimens include: 1  AT: Adriamycin and Taxotere. 2  AC Â± T: Adriamycin and Cytoxan, with or without Taxol or Taxotere. 3  CMF: Cytoxan, methotrexate, and fluorouracil. 4  CEF: Cytoxan, Ellence, and fluorouracil. 5  FAC: fluorouracil, Adriamycin, and Cytoxan. 6  CAF: Cytoxan, Adriamycin, and fluorouracil.
