Success of scale-invariant feature transform (SIFT) image registration is limited when attempted on camera footage taken under water. This is, largely due to the poor image quality inherent to imaging in aquatic environments. In this research we aim to overcome this shortcoming using a new method of pre-processing of true-color imagery taken under water based on the Contrast Limited Adaptive Hi...

BACKGROUND In statistical modeling, finding the most favorable coding for an exploratory quantitative variable involves many tests. This process involves multiple testing problems and requires the correction of the significance level. METHODS For each coding, a test on the nullity of the coefficient associated with the new coded variable is computed. The selected coding corresponds to that as...

Heart rate variability analysis is fast gaining acceptance as a potential non-invasive means of autonomic nervous system assessment in research as well as clinical domains. In this study, a new nonlinear analysis method is used to detect age related changes in the degree of nonlinearity and stochastic nature of heart rate variability signals. The data obtained from an online and widely used pub...

BACKGROUND Articular cartilage injuries are a common clinical problem at the time of ACL reconstruction with an incidence rate of 16-46%. Good results of ACL reconstruction combined with the treatment of chondral lesions have been published in some studies. METHOD After statistical analysis 30 patients were selected and divided in 2 groups. The first group consisted of 15 patients with isolat...

Self-efficacy is an important psychosocial factor that has been reported in many studies to be a mediator between health, behavior, and the environment. However, a valid and reliable measure of self-efficacy in coronary artery disease (CAD) patients has not yet been developed in the Thai language. The aims of this study were to first translate the Cardiac SelfEfficacy Questionnaire (CSEQ) into ...

Background: This study was designed to investigate whether there was an association between ABO blood groups and cardiovascular risk factors in healthy population. Methods: In this cross-sectional study, risk factors screening for cardiovascular disease(CVD) on 5000 healthy persons of Golestan Province, northern Iran, in 2005 was estimated by a questionnaire that included age, sex, physical act...

Aim: to compare the efficacy of cox-2 inhibitor (celebrex) with NSAID (ibuprofen) on the postoperative complications after odontectomy of impacted lower third molar which are pain edema and trismus. Patients and Methods: atotal of 40 patients (20 males, 20 females) with impacted lower third molar divided into two equal groups. Group I: twenty patients treated with 600 mg/12h ibuprofen, GroupII:...

INTRODUCTION Amplification of the fibroblast growth factor receptor 1 (FGFR1) gene has been described in tumors of non-small-cell lung cancer (NSCLC) patients. Prior reports showed conflicting rates of amplification frequency and clinical relevance. MATERIALS AND METHODS We developed a reliable real-time quantitative PCR assay to assess the frequency of FGFR1 amplification and assessed the op...

STUDY OBJECTIVES To compare breast cancer metastases between obese and nonobese women and to evaluate the effect of first-line metastatic chemotherapy in each group. METHOD A retrospective study was performed in an educational institute in Ireland. The study consisted of two parts: the first part was a comparative analysis of metastases development in obese (arm A) and nonobese patients (arm ...
