February 9, , by NCI Staff. Researchers are developing tumor-targeting viruses, like this engineered poliovirus, as potential cancer treatments. For more than a century, doctors have been interested in using viruses to treat cancer, and in recent years a small but growing number of patients have begun to benefit from this approach. Some viruses tend to infect and kill tumor cells.

Metrics details. We selected two controls for each case from patients alive and on MDR-TB treatment at the time that the death occurred incidence-density sampling. We matched the cases and controls on health facility at which they were receiving care. We performed conditional logistic regression to identify the risk factors for mortality. Data from patients 66 cases and controls started on MDR-TB treatment from January 1 to December 31, , was analyzed for this study. However, cases were more likely to be HIV infected while controls were more likely to have attained secondary level education.

School is a competitive place where people have many duties and responsibilities. This requires coping abilities to manage academic stress efficiently. The main sources of stress were examinations, choosing a career path, and family troubles. Competing interests The authors have declared that no competing interests exist. Many criteria are used to categorize stress, and this leads to many terms for different types of stress.
Radiation therapy or radiotherapy , often abbreviated RT , RTx , or XRT , is a therapy using ionizing radiation , generally provided as part of cancer treatment to control or kill malignant cells and normally delivered by a linear accelerator. Radiation therapy may be curative in a number of types of cancer if they are localized to one area of the body. It may also be used as part of adjuvant therapy , to prevent tumor recurrence after surgery to remove a primary malignant tumor for example, early stages of breast cancer. Radiation therapy is synergistic with chemotherapy , and has been used before, during, and after chemotherapy in susceptible cancers.
