RESUMO
KIAA1199 gene is an important member of the HUGE database, and is involved in the transduction of intracellular signaling pathway through epigenetic mechanism, regulating the cell growth, differentiation, apoptosis and migration. Recent studies showed that KIAA1199 gene is closely related to tumorigenesis and tumor development. The expression of KIAA1199 gene is highly upregulated in many types of tumor, especially in digestive system neoplasms, and having the effects of promoting proliferation, adhesion, invasion and migration of tumor cells. This article reviewed the role of KIAA1199 gene in digestive system neoplasms.
RESUMO
In order to meet the requirements of ultrasound bone density measurement, we proposed a software solution to improve the accuracy and speed of measurement of bone mineral density of the ultrasound bone densitometer. We used a high-speed USB interface chip FT232H, along with a high-speed AD converter chip to calculate speed of sound (SOS), broadband ultrasound attenuation (BUA ) and other bone density parameters in the PC software. This solution improved the accuracy of the measurement data, reduced the measurement time and increased the quality of the displayed image. It is well concluded that the new software can greatly improve the accuracy and transmission speed of bone density measurement data through a high-speed USB interface and a software data processing technology.
