Arginase 2, inducible- and endothelial-nitric-oxide synthase (iNOS and eNOS), indoleamine 2,3-dioxygenase (IDO) and TGF-beta, might impair immune functions in prostate cancer (PCA) patients. However, their expression was not comparatively analysed in PCA and benign prostatic hyperplasia (BPH). We evaluated the expression of these genes in PCA and BPH tissues. Seventy-six patients (42 BPH, 34 PC...

The selection of appropriate wavelets is an important target for any application. In this paper Face recognition has been performed using Principal component analysis (PCA), Gaussian based PCA and Gabor based PCA. PCA extracts the relevant information from complex data sets and provides a solution to reduce dimensionality. PCA is based on Euclidean distance calculation which is minimized by app...

4 DPA derivative samples are difficult to obtain. The excellent work of W. A. SCHRGEDER et al. utilized column chromatography to identify. and estimate N-nitrosoand nitrodiphenylamine products in smokeless powder· 2 however, the efficiency of separation and X .0 n -1 .-1 method of locating the products proved unsatisfactory for our use.

The energy states of electrons are given by unique combinations of n=1, 2, ...; l=0, 1, ..., n-1; ml = -l, ..., -1, 0, 1, ..., l; and ms = ±1/2. The sequence and occupancy of allowed states can be stated as the Periodic Table and the energy of electron transitions can be calculated precisely in QED. In the second half of the 20 century, a nuclear version of the wave-equation (Eq. 2) led directl...

respectively. In either case, choosing α̂(ω) = δ(ω) results in a variance proportional to that of the integrand. These equations provide different insight into the choice of importance function for variance reduction. Eq. 2 suggests that ideally, g(x) = 1/α(x) should be chosen so that α̂(ω) contains all its energy at frequencies where the square of the integrand has no energy. Eq. 3, on the other...

PURPOSE Opioid-based intravenous patient-controlled analgesia (IV-PCA) is a popular method of postoperative analgesia, but many patients suffer from PCA-related complications. We hypothesized that PCA was not essential in patients undergoing major abdominal surgery by minimal invasive approach. METHODS Between February 2013 and August 2013, 297 patients undergoing laparoscopic surgery for col...

Iron is an essential element in the construction materials for fission and fusion reactors. Due to its complexity, evaluation of iron cross sections continues represent a challenge international nuclear data community. A comprehensive validation any new (and computational procedure) against experimental benchmarks therefore needed. The shielding benchmark database SINBAD includes relatively num...

BACKGROUND Postoperative delirium is relatively common. However, the relationship between intravenous patient-controlled analgesia (IV-PCA) and delirium has not been thoroughly investigated. The aim of this study was to evaluate the effects of IV-PCA on the prognosis of postoperative delirium in patients undergoing orthopedic surgery. METHODS Medical records of 129 patients with postoperative...

Principal component analyses (PCA) has been widely used in reduction of the dimensionality of datasets, classification, feature extraction, etc. It has been combined with many other algorithms such as EM (expectation-maximization), ANN (artificial neural network), probabilistic models, statistic analyses, etc., and has its own development such as MPCA (moving PCA), MS-PCA (multi-scale PCA), etc...
