Establishing a threshold for 131I bioassay in nuclear medicine personnel.

30 Oct 2008 Since the late 1970's, manufacturers in nuclear medicine have reformulated the I solution to reduce the volatility of the iodine. There has also been an increase in use of the iodide in encapsulated form. Per the requirement of the current U.S. ... Read more...

Use of high throughput qPCR screening to rapidly clone low frequency tumour specific T-cells from peripheral blood for adoptive immunotherapy.

18 Oct 2008 BACKGROUND: The adoptive transfer of autologous tumor reactive lymphocytes can mediate significant tumor regression in some patients with refractory metastatic cancer. However, a significant obstacle for this promising therapy has been the ... Read more...

Viability analysis and apoptosis induction of breast cancer cells in a microfluidic device: effect of cytostatic drugs.

29 Sep 2008 Breast cancer is the leading cause of cancer deaths among non-smoking women worldwide. At the moment the treatment regime is such that patients receive different chemotherapeutic and/or hormonal treatments dependent on the hormone receptor status, ... Read more...
