LncRNA LINC00689 Promotes the Progression of Gastric Cancer Through Upregulation of ADAM9 by Sponging miR-526b-3p.

Introduction: Increasing studies have demonstrated that noncoding RNAs, including miRNAs and lncRNAs, have vital roles in mediating cancer progression. However, the expression features and biological functions of LINC00689 in gastric cancer (GC) remain largely unknown. This study was designed to investigate the functions of LINC00689, miR-526b-3p and ADAM9 as well as their interactions in GC.

Characteristics Analysis of the Thyroid Gland Surface of Normal Human with Fourier Transform Infrared (FTIR) Spectra.

In order to obtain 240 cases of the surface Fourier transform infrared (FTIR) spectra of normal human thyroid gland, 120 healthy volunteers were enrolled in this study and scanned by using two mid-infrared optical fibers equipped with an attenuated total reflectance (ATR) to probe through the skin of two lobes of thyroid gland. Then whether there were differences between the surface FTIR spectra of the right lobe and that of the left part of the normal human thyroid gland was explored by comparing the 35 variables of 12 bands, including peak positions, relative intensity ratios and full width at half maximum of FTIR spectrums. Also the spectra characteristics of unique absorbent bands that represent changes of structure and quantity of variance biochemical substances such as nucleic acids, proteins and carbohydrates were illustrated.

[Recent progress in diagnosis of malignant tumors by Fourier transform infrared spectroscopy].

Malignant tumors pose a serious threat to mankind health and life. As a result, early diagnosis is very important. In recent years, Fourier transform infrared spectroscopy has shown enormous development potential of cancer diagnosis.
