Context:
Alimta is used to treat two types of cancer: pleural mesothelioma (cancer of the lining of the lungs that is usually caused by exposure to asbestos). Alimta is used together with cisplatin (another anticancer medicine) when the cancer is unresectable (cannot be removed by surgery alone) and malignant (has spread, or is likely to spread easily, to other parts of the body), in patients who have not received chemotherapy (medicines for cancer) before advanced or metastatic non-small cell lung cancer that is not affecting the squamous cells. Alimta is used in combination with cisplatin in patients who have not been treated before, and on its own in patients who have received another type of chemotherapy in the past. The medicine can only be obtained with a prescription. How is Alimta used? Alimta should <t>only</t> be given under the supervision of a doctor who is qualified in the use of anticancer chemotherapy. The recommended dose of Alimta is 500 mg per square metre of body surface area (calculated using the patient s height and weight).

Target lemma: locally
Target surface form: locally
Context:
The active substance in Alimta, pemetrexed, is a cytotoxic medicine (a medicine that kills cells that are dividing, such as cancer cells), which belongs to the group antimetabolites. In the body, pemetrexed is converted into an active form that blocks the activity of the enzymes that are involved in producing nucleotides (the building blocks of DNA and RNA, the genetic material of cells). How has Alimta been studied? For the treatment of malignant pleural mesothelioma, Alimta has been studied in one main study in 456 patients who had not received chemotherapy for their disease before. The effects of Alimta in combination with cisplatin were compared with those of cisplatin alone. For the treatment of non-small cell lung cancer, the effects of Alimta were compared with those of docetaxel (another anticancer medicine) in one study involving 571 patients with <t>locally</t> advanced or metastatic disease who had received chemotherapy in the past. Alimta was also compared with gemcitabine (another anticancer medicine), both in combination with cisplatin, in a study involving 1,725 patients who had not received chemotherapy for lung cancer in the past.

Context:
The results of the studies showed that Cerenia was more effective than the placebo: less vomiting was seen in dogs that received the medicine than in dogs that received a placebo, both in the treatment or in the prevention of vomiting. The treatment of a vomiting dog should be started with the injection, since vomiting animals might not be able to keep a tablet down (as they might throw the intact tablet up again). For follow-up treatment, the animal owner can administer the tablets to the dog. Also, the treatment of vomiting should only be together with other supportive measure or other veterinary therapy while addressing the underlying causes of the vomiting. What is the risk associated with Cerenia? Cerenia was generally <t>well</t> tolerated when administered daily at dosages up to 5 times the recommended doses for an extended period of time (up to 3 times the recommended maximum duration of treatment). What are the precautions for the person who gives the medicine or comes into contact with the animal?

Context:
According to a nationwide survey taken a year ago, nearly a third of England's church bells are no longer rung on Sundays because there is no one to ring them. It is easy to see why the ancient art is on the ropes. The less complicated version of playing tunes on bells, as do the carillons of continental Europe, is considered by the English to be childish, fit only for foreigners. Change-ringing, a mind-boggling exercise the English invented 380 years ago, requires physical dexterity -- some bells weigh more than a ton -- combined with intense mental concentration. Proper English bells are started off in "rounds, "from the highest-pitched bell to the lowest -- a simple descending scale using, in larger churches, as many as 12 bells. <t>Then</t>, at a signal, the ringers begin varying the order in which the bells sound without altering the steady rhythm of the striking. Each variation, or change, can occur only once, the rules state.
