PMID: 25806167
Transl Lung Cancer Res. 2012 Jun;1(2):111-21. doi: 10.3978/j.issn.2218-6751.2011.12.07.

Lung cancer is a leading cause of tumor-related death worldwide through years. Efforts to individualize lung cancer therapy to improve prognosis nowadays employ molecular analyses besides routine histopathological examination of tissue samples. In general, tissues are provided by bronchoscopy,...

InGaAs quantum wire (QWr) intermediate-band solar cell-based nanostructures grown by molecular beam epitaxy are studied. The electrical and interface properties of these solar cell devices, as determined by current-voltage (I-V) and capacitance-voltage (C-V) techniques, were found to change with...

Personalized Medicine's Bottleneck: Diagnostic Test Evidence and Reimbursement.

Journal of personalized medicine

Cohen JP, Felix AE.
PMID: 25563222
J Pers Med. 2014 Apr 04;4(2):163-75. doi: 10.3390/jpm4020163.

BACKGROUND: Personalized medicine is gradually emerging as a transformative field. Thus far, seven co-developed drug-diagnostic combinations have been approved and several dozen post-hoc drug-diagnostic combinations (diagnostic approved after the drug). However, barriers remain, particularly with respect to reimbursement. Purpose,...

Discrete clouds of neutral gas between the galaxies M31 and M33.
