Calmodulin (CaM) is a multifunctional receptor of intercellular Ca2+, which under different physiological conditions or at different developmental stages plays different roles in different tissues and cells. This study aimed to investigate the involvement of spatial expression and coexistence of CaM and actin in directed differentiation of rat cortical(More)
OBJECTIVE To investigate the effect of applying a tourniquet on perioperative blood loss and shortterm effectiveness in primary total knee arthroplasty (TKA). METHODS A total of 94 patients (94 knees) with osteoarthritis underwent primary TKA between September 2010 and December 2011, whose data met the inclusion criteria and were retrospectively analyzed.(More)
The selection window of selection algorithm used in traditional automatic focus window concentrates mainly on the center of image, so the randomly distributed cells would always be out of focus. To address this problem, on the basis of analyzing the performance of selection algorithm of different focusing windows, a modified auto-focus window algorithm upon(More)
Microbial degradation of estrogenic compounds can be affected by the nitrogen source and background carbon in the environment. However, the underlying mechanisms are not well understood. The objective of this study was to elucidate the molecular mechanisms of estrone (E1) biodegradation at the protein level under various background nitrogen (nitrate or(More)
This paper presents the modelling and analysis of a piezoelectric annular stator structure for a new in-situ dynamic balance regulator which is driven by the in-plane bending vibration of the stator. The mathematical model for the in-plane vibration is first developed using an analytical method to determine the theoretical excitation frequency. The(More)
In order to counterbalance the unfairness to rare class on using Support Vector Machine to credit assess for imbalanced dataset from commercial banks, an adjustment Method of the separating hyperplane is proposed in the paper. Based on Fisher discrimination, the projected class mean and variance are got by projecting two classes samples onto the normal(More)
In this paper, a new piezoelectric dynamic balance regulator, which can be used in motorised spindle systems, is presented. The dynamic balancing adjustment mechanism is driven by an in-plane bending vibration from an annular piezoelectric stator excited by a high-frequency sinusoidal input voltage. This device has different construction, characteristics(More)
