BACKGROUND The efficacy of paclitaxel-coated balloons (PCB) for restenosis prevention has been demonstrated in humans. However, the mechanism of action for sustained drug retention and biological efficacy following single-time drug delivery is still unknown. METHODS AND RESULTS The pharmacokinetic profile and differences in drug concentration (vessel surface vs arterial wall) of two different...

BACKGROUND In the present study, we aimed to compare clinical and radiographic outcomes between hook plate fixation and coracoclavicular (CC) ligament reconstruction for the treatment of acute unstable acromioclavicular (AC) joint dislocation. METHODS Forty-two patients who underwent surgery for an unstable acute dislocation of the AC joint were included. We divided them into two groups accor...

Purpose In retinoblastoma, adjuvant chemotherapy after enucleation is given in eyes with histopathological high-risk features (HRFs) to reduced mortality. Anterior chamber seeds (AC seeds) on histopathological evaluation are a contentious finding. This study attempts to determine the effect of AC seeds on the survival rate. Methods This is a retrospective case record review. Eyes were divided...

In this paper, we give a generalized Cline?s formula for the Drazin inverse. Let R be ring, and let a, b, c, d ? satisfying (ac)2 = (db)(ac), (db)2 (ac)(db), b(ac)a b(db)a, c(ac)d c(db)d. Then ac Rd if only bd Rd. case, (bd)d b((ac)d)2d: We also present formulas group inverses. Some weaker conditions in Banach algebra are investigated. These extend main results of on g-Drazin inverse Liao, Chen...

BACKGROUND Self-report measures indicate that Yoga practices are perceived to reduce stress; however, molecular mechanisms through which YB affects stress are just beginning to be understood. While invasive sampling such as blood has been widely used to measure biological indicators such as pro-inflammatory biomarkers, the use of saliva to measure changes in various biomolecules has been increa...

The objectives of the current study were to analyze the effects of orofacial myofunctional therapy (OMT) on the treatment of subjects with associated articular and muscular temporomandibular disorders (TMD). Thirty subjects with associated articular and muscular TMD, according to the Research Diagnostic Criteria (RDC/TMD), were randomly divided into groups: 10 were treated with OMT (T group), 1...

in this study, a manganite sample with a nominal formula of la0.9sr0.1mno3 was prepared by the microwave assisted sol-gel method and annealing at various temperatures. the structural and magnetic properties of the samples were investigated by xrd, fesem and ac susceptometer, respectively. xrd analysis showed that the samples are a nearly single phase. fesem micrographs showed that by increasing...

Objective(s):N-myc downstream regulated gene 2 (NDRG2) is a candidate gene for tumor suppression. The expression of NDRG2 is down-regulated in several tumors including lung cancer. The aim of this study was to explore the effect of NDRG2 overexpression on invasion, migration, and enzymatic activity of matrix metalloproteinase-2 (MMP-2) and -9 (MMP-9) in human lung adenocarcinoma A549 cells.  Ma...

Plagiarism detection in programming assignments is still a very problematic issue, in terms of economic costs, conceptual controversy, legal risks, and detection algorithms and heuristics. In this paper, we present AC: an integrated environment for the study of plagiarism and a powerful tool for its detection. We explain the special design of AC, prepared for unlimited improvement and external ...

Attentional control (AC) is an individual difference variable indexing the ability to voluntarily focus attention and shift attention when desired. AC is thought to impact the experience of fear by facilitating the disengagement of attention from threat and promoting the deployment of attentional resources toward regulatory or coping strategies. Whereas previous research has focused on visual t...
