Dynamics of C-reactive protein level after orthopedic surgeries.

Background: Only two studies present the results of the dynamics of C-reactive protein (CRP) after a large number of orthopedic surgeries. The aim of the study was to investigate the dynamics of CRP levels and determine the influence of various factors on the CRP level after various orthopedic surgeries using big data tools.

Methods: A total of 16042 operated patients were included in the study.

Determination of traces of uranium and thorium in titanium and copper used for the construction of the Russian Emission Detector 100 by inductively coupled plasma mass spectrometry.

The Russian Emission Detector 100 (RED-100) under construction at the National Research Nuclear University MEPhI (Moscow Engineering Physics Institute) is designed to detect the presently undiscovered effect of coherent neutrino scattering. One of the factors limiting the sensitivity of the detector is the spontaneous decay of uranium and thorium in the detector materials. Radioactive impurities in detector materials at levels of parts per billion can significantly affect the sensitivity.
