In the crowded wards of African hospitals, coughs and bony bodies tell the story of a deadly return. Tuberculosis (TB), supposedly defeated 40 years ago, is back, riding on the AIDS epidemic, and the world is ill-prepared, says the relief agency Medecins Sans Frontieres (MSF).
The impact of HIV/AIDS in Southern Africa is now well recognised, but the critical question is whether enough funding has been allocated to deal with the epidemic, a report by the Human Sciences Research Council (HSRC) said.
Findings could lead to more effective therapy for deadly agent A research team led by scientists at Beth Israel Deaconess Medical Center (BIDMC) and Harvard Medical School (HMS) has identified a group of small molecules that inhibit a deadly toxin associated with inhalational anthrax.
Colorectal cancer which includes cancer of the colon, rectum, anus, and appendix is, after lung cancer, a leading cause of cancer related deaths in certain parts of the world. Currently only a third to one half of patients with metastatic colorectal cancer respond to traditional chemotherapy. Latest strategy in treatment is being targeted at a specific type of receptor, the EGFR found on a cell's surface. The epidermal growth factor receptor (EGFR) found on the surface of tumour cells, has been shown to contribute to the growth and spread of many different types of solid tumours. Activation...
Researchers with the Mayo Clinic discover that a donor kidney protects itself once transplanted into a new body. A long-standing medical discussion about how transplanted organs survive in a new body has received provocative new evidence from Mayo Clinic research. It shows a donated kidney survives in a new body by turning on a protective mechanism to shield it from the hostile environment of the patient's immune system. The results are published in this month's American Journal of Transplantation.
