BRCA1 mislocalization associated with breast carcinogenesis and poor prognosis in Taiwanese women.

We aimed to elucidate whether and how BRCA1 mislocalization [including membranous nuclear (MN) forms and negative patterns] is associated with the occurrence and the prognosis of breast cancer in young Taiwanese women. A case-control study was carried out to enroll 84 patients with breast cancer and 81 patients with benign breast disease. The subcellular localization of BRCA1 was examined using immunofluorescent assays on fresh tissue touch-imprinting slides to classify staining results into diffuse nuclear (DN), MN, and negative staining.

[Near infrared distance sensing method for Chang'e-3 alpha particle X-ray spectrometer].

Alpha particle X-ray spectrometer (APXS) is one of the payloads of Chang'E-3 lunar rover, the scientific objective of which is in-situ observation and off-line analysis of lunar regolith and rock. Distance measurement is one of the important functions for APXS to perform effective detection on the moon. The present paper will first give a brief introduction to APXS, and then analyze the specific requirements and constraints to realize distance measurement, at last present a new near infrared distance sensing algorithm by using the inflection point of response curve.

[Temperature effect correction for Chang'E-3 alpha particle X-ray spectrometer].

Alpha particle X-ray spectrometer (APXS) is one of the payloads of Chang'E-3 lunar rover of China's Lunar Exploration Project. The present paper introduces briefly the components of APXS, how it works and its working environment on the lunar surface. The environmental temperature effect has been studied with simulations and experiments, and the results show that the temperature of the APXS sensor will be varying during the measuring on the lunar surface.
