Ninjurin 2 rs118050317 gene polymorphism and endometrial cancer risk
Cancer Cell International, 2021 Background Endometrial cancer is one of the most common female reproductive system tumors. Ninjurin2 (NINJ2) is a new adhesion factor. As a vascular susceptibility gene, it is highly expressed in other cancers and promotes the growth of cancer cells.

Correlations Between Life-Detection Techniques and Implications for Sampling Site Selection in Planetary Analog Missions. [PDF]
Astrobiology, 2017 We conducted an analog sampling expedition under simulated mission constraints to areas dominated by basaltic tephra of the Eldfell and Fimmvörðuháls lava fields (Iceland). Sites were selected to be “homogeneous” at a coarse remote sensing resolution (10–

MiR-483-3p regulates oxaliplatin resistance by targeting FAM171B in human colorectal cancer cells
Artificial Cells, Nanomedicine, and Biotechnology, 2019 Oxaliplatin resistance limits the efficiency of treatment for colorectal cancer (CRC). Studies have shown that abnormal expression of microRNAs (miRNAs) were associated with tumorigenesis, cancer development and chemoresistance. The purpose of this study

Simultaneous Life Detection and Localization Using a Wideband Chaotic Signal with an Embedded Tone. [PDF]
Sensors (Basel), 2016 A hybrid life detection radar system which transmits a wideband chaotic signal containing an embedded single-tone is proposed. The chaotic signal is used for target localization by the time-domain correlation method and synthetic aperture technique, and ...

How to Detect Life on Icy Moons [PDF]
Astrobiology, 2018 The icy moons of the outer Solar System present the possibility of subsurface water, habitable conditions, and potential abodes for life. Access to evidence that reveals the presence of life on the icy moons can be facilitated by plumes that eject material from the subsurface out into space.
