Scientists from the Antwerp Institute of Tropical Medicine, Antwerp University Hospital and Antwerp University have tested a new 'therapeutic vaccine' against HIV on volunteers. The participants were so to say vaccinated with their own cells. The researchers filtered certain white blood cells out of the volunteer's blood, 'loaded' them outside the body and then gave them back. The immune system of the testees was better than before in attacking and suppressing the virus, the scientists reported in the top journal AIDS. But they still cannot cure the disease. http://medicalxpress.com/news/2012-02-hiv-vaccine-people.html HIV & AIDS Mon, 13 Feb 2012 11:19:26 EST news248354335 Although chemotherapy is used to kill cancer cells, it can also have a strong toxic effect on normal cells such as bone marrow and blood cells, often limiting the ability to use and manage the chemotherapy treatment. Researchers at Fred Hutchinson Cancer Research Center reported at today's annual meeting of the American Society of Gene and Cell Therapy in Seattle that one possible approach to reduce this toxic effect on bone marrow cells is to modify the cells with a gene that makes them resistant to chemotherapy. http://medicalxpress.com/news/2011-05-gene-modified-stem-cells-bone-marrow.html Cancer Sat, 21 May 2011 05:36:52 EST news225174980 New research shows a drug commonly used to treat sickle cell anemia in adults reduces bouts of acute pain and a pneumonia-like illness, cuts hospitalization time and eases other symptoms of the disease in young patients. Results of the randomized, double-blind trial mark a dramatic advance in treatment of children with the inherited blood disorder. http://medicalxpress.com/news/2011-05-sickle-cell-anemia-drug-safe.html Medications Thu, 12 May 2011 18:30:01 EST news224428066 A study published in the current issue of Cell Transplantation has demonstrated for the first time that endothelial cells derived from cryopreserved human umbilical cord blood cells are phenotypically, as well as structurally and functionally, indistinguishable from freshly isolated endothelial cells. The success of the author's work eliminates the necessity of performing cell isolation procedures prior to their use in clinical transplantation. http://medicalxpress.com/news/2011-05-cryopreserved-endothelial-progenitor-cells-phenotypically.html Medical research Wed, 11 May 2011 15:13:15 EST news224345565
