Abstract: Methods and apparatuses are disclosed for detecting a presence of a mismatched pair in an oligonucleotide duplex that is attached to a solid substrate using an atomic force microscope. In particular, methods and apparatuses of the invention allow qualitative and quantitative analysis of the presence of a mismatched pair in a sample of oligonucleotide duplex using an atomic force microscope comprising an AFM cantilever that includes a DNA mismatch repair protein. Methods and apparatuses of the invention allow detection of gene mutation without a need for amplification, labeling, or modification of the sample. Such apparatuses and methods can be used in a wide variety of clinical diagnostic applications including detection and/or analysis of biomarkers related to, but not limited to, cancer, trauma, sepsis, aseptic inflammation, myocardial infarction, stroke, transplantation, diabetes, sickle cell disease, as well as other clinical conditions.

Abstract: The present disclosure is related to a perfusable-type bio-dual proximal tubule cell construct and a producing method thereof capable of applying an in vitro artificial organ model configured to include a first bioink comprising a decellularized substance derived from a mammalian kidney tissue and human umbilical vascular endothelial cells (HUVECs) and a second bioink comprising the decellularized substance and renal proximal tubular epithelial cells (RPTECs), wherein the first bioink and the second bioink are coaxial and printed in tubular constructs having different inner diameters.
According to the present disclosure, it is possible to use the renal proximal tubule-on-a-chip as a bioreactor capable of observing a biological drug reaction similar to a real drug by perfusing various drugs to the renal proximal tubule-on-a-chip.

Abstract: A device for learning a fog-invariant feature includes a fog-pass filter, which is trained such that fog factors of the same fog domain approach each other and fog factors of different fog domains are apart from each other so as to determine a fog state of an input image as a fog factor, and a segmentation network, which is trained such that a fog style gap between the different fog domains decreases, in which training of the fog-pass filter and training of the segmentation network are alternatively performed by using three fog domain datasets.
