Molecular and clinical oncology

Kim JW, Jeon YJ, Jang MJ, Kim JO, Chong SY, Ko KH, Hwang SG, Oh D, Oh J, Kim NK.
PMID: 26137281
Mol Clin Oncol. 2015 May;3(3):639-648. doi: 10.3892/mco.2015.520. Epub 2015 Feb 27.

Folate has essential roles in DNA synthesis, repair and methylation. Folate metabolism-related gene variants may modulate the levels of this vitamin and affect the cancer risk. Thus, whether these polymorphisms play an important role in carcinogenesis, particularly colorectal cancer...

BACKGROUND: Interleukin-22 (IL-22), a cytokine with important functions in anti-microbial defense and tissue repair, has been recently suggested to have beneficial effects in obesity and metabolic syndrome in some but not in other studies. Here, we re-examined the effects...

Stereo Vision-Based High Dynamic Range Imaging Using Differently-Exposed Image Pair.

Sensors (Basel, Switzerland)

Park WJ, Ji SW, Kang SJ, Jung SW, Ko SJ.
PMID: 28640235
Sensors (Basel). 2017 Jun 22;17(7). doi: 10.3390/s17071473.

In this paper, a high dynamic range (HDR) imaging method based on the stereo vision system is presented. The proposed method uses differently exposed low dynamic range (LDR) images captured from a stereo camera. The stereo LDR images are...
