Abstract: A pixel includes: a storage capacitor connected between a first power supply voltage and a gate node; a first transistor including a gate electrode connected to the gate node; a second transistor to transfer a data signal to a source of the first transistor in response to a scan signal; a third transistor to diode-connect the first transistor in response to the scan signal, and including first and second sub-transistors serially connected between the gate node and a drain of the first transistor; a fourth transistor to transfer an initialization voltage to the gate node in response to an initialization signal, and including third and fourth sub-transistors serially connected between the gate node and the initialization voltage; and an organic light emitting diode including a cathode connected to a second power supply voltage. At least one of the second and fourth sub-transistors includes a bottom electrode.

Abstract: The present disclosure relates to a serum exosomal SF3B4 marker composition for diagnosing early stage hepatocellular carcinoma for noninvasive in vitro diagnosis, wherein, by analyzing an expression level of SF3B4 in plasma proteins as well as expression of SF3B4 in exosomes present in sera of hepatocellular carcinoma patients, the possibility as the most suitable liquid biopsy marker was identified, and a new noninvasive biomarker with high diagnostic accuracy in early stage hepatocellular carcinoma for which no reliable biomarker exists at this present was discovered. As such, by using exosomes to identify cancer cell genomes and proteomes without biopsy, the exosomes are highly applicable in the future as a diagnostic biomarker that is useful in a disease group with a high risk in the biopsy such as hepatocellular carcinoma.

Abstract: A clamp locator includes: a body having an attachment portion, which is attached to a band of a hose clamp; a head portion extending from the body; an end portion extending angularly from the head portion; a clip portion bendably connected to the end portion; and an engaging portion extending angularly from the clip portion and having a plurality of teeth. The attachment portion has at least one projection, which is meltable.
