AIM We aimed to evaluate the hemostatic effects and the clinical outcomes of preoperative and postoperative cryoceutical treatment (C-tx) following total knee arthroplasty. PATIENTS AND METHOD 42 patients received C-tx both preoperatively, and postoperatively. In the control group, 45 patients did not receive any C-tx. Amount of bloody drainage and verbal rating pain scores were noted. RESU...
Let V and W be two real vector spaces and let &sim be a relation on both V and W. A linear function T : V → W is said to be a linear preserver (respectively strong linear preserver) of &sim if Tx &sim Ty whenever x &sim y (respectively Tx &sim Ty if and only if x &sim y). In this paper we characterize all linear functions T : M_{n,m} → M_{n,k} which preserve or strongly preserve multivariate an...
Fluorine and chlorine X‐ray count rates are known to vary significantly during electron probe microanalysis (EPMA) of apatite. Since the rate, timing, and magnitude of this variation are a function of apatite orientation and composition, as well as EPMA operating conditions, this represents a significant problem for volatile element analysis in apatite. Although the effect is thought to be an i...
Molecular dynamics (MD) simulations have been used to study surface reaction dynamics of Si and Si02 etching by halogens. To perform classical MD simulations for Si02 etching reaction by halogens (C1 or F), we have constructed new sets of twoand three-body interatomic potential functions based on potential energy data obtained from ab initio quantum mechanical calculations of the electronic sta...
Halogens in the troposphere are increasingly recognized as playing an important role for atmospheric chemistry, and possibly climate. Bromine and iodine react catalytically to destroy ozone (O3), oxidize mercury, and modify oxidative capacity that is relevant for the lifetime of greenhouse gases. Most of the tropospheric O3 and methane (CH4) loss occurs at tropical latitudes. Here we report sim...
introduction: the advent of dual-modality pet/ct scanners has revolutionized clinical oncology by improving lesion localization and facilitating treatment planning for radiotherapy. in addition, the use of ct images for ct-based attenuation correction (ctac) decreases the overall scanning time and creates a noise-free attenuation map (6map). ctac methods include scaling, s...
In this research at the first Promethazine drug and its fullerene derivative were optimized. NMR calculations for the complexes were carried out at the B3LYP/6-31G*quantum chemistry level. Promethazine is not used as an antihistaminic drug for anyone. In the pharmaceutical composition of promethazine (RS) - N, N-dimethyl-1- (10H-Phenothaiazin-10 yl) -propen-2-amino, two aromatic rings In this s...
ABSTRACT In this paper, we present the X-ray analysis of Sloan Digital Sky Survey DR8 redMaPPer (SDSSRM) clusters using data products from XMM Cluster (XCS). total, 1189 SDSSRM fall within XMM–Newton footprint. This has yielded 456 confirmed detections accompanied by luminosity (LX) measurements. Of these clusters, 381 have an associated temperature measurement (TX). represents one largest samp...
OBJECTIVES To evaluate the efficacy of a microprocessed phototherapy (PT) system with five high intensity light emitting diodes (Super LED) for the treatment of neonatal hyperbilirubinemia of premature infants. METHODS Randomized clinical trial using Super LED phototherapy in the study group and twin halogen spotlight phototherapy in the control group. A stratified blocked randomization, base...
