Assessing the biomechanical strength of trabecular bone in vitro using 3D anisotropic nonlinear texture measures: the scaling vector method

We introduce the scaling vector method (SVM): a technique to obtain local non-linear structural information from data sets suitable in cases where anisotropy plays an important role. We apply the SVM to High Resolution Magnetic Resonance Images (HRMRI) of human proximal femur specimens IN VITRO which contain a large portion of bone tissue forming a complex network of mineralized trabeculae oriented along the major stress lines. By means of the SVM, we extract a 3D non-linear local anisotropic texture measure which we use to compare with similar isotropic texture measures, bone mineral density (BMD) and standard isotropic 2D (linear) morphometric parameters in the prediction of the biomechanical properties of the trabecular bone. Our results show that structural non-linear anisotropic texture measures which account for the preferential direction of the trabeculae are superior to isotropic and bulk measures in the prediction of the mechanical properties of the human proximal femur in vitro.
A study on the correlation measurement errors in structural equation modeling (SEM) analysis

SEM have two part that is structural model and measurement model. Composite structural model and measurement model testing enable to test the measurement error as part indivisible of SEM. Based on that condition, SEM can be used and developed to know about a correlation measurement influence in exogen variable and endogen variable, and correlation measurement influence between exogen variable toward structural coefficient. The research use 7 secunder data. Correlation with modification indices information represents the decrease in chi-square and change value of CMINDF and RMSEA to be better whereas at structural coefficient and p-value have not significant change such as at data 1 get structural coefficient and p-value are 0,313 and 0,002, and after correlation error that value be 0,316 and 0,001. The conclusion is that the influence of the correlation measurement error in exogen variable, in endogen variable and between exogen variable not change structural the coefficient significantly.
Activity Budgets and Prey Consumption of Sea Otters (Enhydra lutris kenyoni) in Washington

Northern sea otters (Enhydra lutris kenyoni) were extirpated from the Washington coast in the early 1900s. Reintroductions of sea otters from Amchitka Island, Alaska, occurred in 1969 and 1970. By 2005, 814 sea otters occupied a range from Destruction Island north to Makah Bay. The focus of this study was to investigate diurnal activity budgets and variability in prey consumption at four locations in the current Washington sea otter range to test hypotheses concerning population growth potential and local impact of sea otters on prey availability. Overall, sea otters primarily spent their daylight hours resting (62.3%), grooming (19.7%), and feeding (7.6%). These activities varied by location. Diet consisted predominantly of crabs, clams, and sea stars. In each study area, one main prey item comprised 33.4 to 64.4% of the total prey consumed; however, the main prey item differed among locations. Of the foraging dives observed, 81.4% were successful. Average dive duration was 35.6 s; however, this varied among locations as well. The study locations were utilized differently—some as resting sites and others as feeding sites. The low diurnal feeding activity found in this study indicates that food availability was high, suggesting that this Washington population of sea otters is currently below equilibrium density.
An account of the real-life hepatitis C management in a single specialized viral hepatitis treatment centre in Egypt: results of treating 7042 patients with 7 different direct acting antiviral regimens

ABSTRACT Background: A large Egyptian treatment program for HCV was launched in2014 after the introduction of direct-acting antiviral agents (DAAs). This program depended mainly on establishing specialized independent centres for HCV treatment. These centres represent the major strengths in the Egyptian model of care, as they provide integrated care for HCV patients and have enabled Egypt to treat more than one million patients in 3 years. The New Cairo Viral Hepatitis Treatment Center (NCVHTC) is an example of these specialized centres. Methods: The Egyptian experience in the management of HCV was evaluated by analysing the data of real-life HCV management in the NCVHTC from 2014 to 2017. Results of different treatment regimens in addition to their strengths, limitations and areas for improvement are discussed in this report. Results: A total of 7042 HCV patients have been evaluated for treatment in the NCVHTC. Among them, 5517 patients received treatment by seven different DAA regimens with excellent results. Conclusions: All regimens were highly effective at treating HCV in a real-life setting, apart from SOF/RBV, which was the least effective. A nationwide screening program and enhancing the follow-up of treated patients are the main missing pillars in the Egyptian model.
The Impact of Translators' Academic Experience on Their Translation Quality.

Translators differ from each other in many ways in terms of their knowledge and professional conditions that may directly influence their translation. The present study aimed at investigating the impact of translators’ academic experience on their translation quality. Following a causal-comparative study, a sample of 100 male and female professional translators, working in official or non-official translation offices or as freelance translators, were selected using purposive sampling method. The participants were divided into two groups each containing 50 individuals with and without a degree in translation, respectively. The participants were asked to translate a paragraph including 232 words, from Orwell’s 1984 novel, to assess their translation quality. To do this, Waddington’s model D (2001) was used as the marking system. For data analysis, inferential statistical procedures including independent sample t-test was used in order to investigate the research hypothesis. Results showed that translators’ academic experience in translation significantly affects their translation quality. The results also clearly depicted that the translation quality of translators with academic experience was significantly better than that of those without academic experience.
Sulforaphane Induces Cell Cycle Arrest, Migration, Invasion, and Apoptosis in Epithelial Ovarian Cancer Cells

Objectives : Isothiocyanates (ITC) has long been shown to demonstrate chemopreventive properties. Sulforaphane (SFN) is a major ITC present in broccoli and other cruciferous vegetables. We reviewed the current literatures of SFN on ovarian carcinoma cell lines. Methods : Studies were conducted on the effects of SFN on the growth of the OVCAR-3, MDAH 2774 and SKOV-3 ovarian carcinoma cell lines. Chuang et al . evaluated the effect of SFN on ovarian cancer cell cycles. Subsequently Chaudhuri et al . determined the specific pathway that was affected and Bryant et al . explored the signaling mechanisms through which SFN influences the cell growth and proliferation in ovarian cancer cell lines. Results : Chuang et al . showed a concentration dependent decrease in cell density. Analysis of cell cycle phase progression revealed a decrease in the cell populations in S and G2M phases, with an increase of G1 cell population, indicating a G1 cell cycle arrest. The degree of decrease in the replicating population was concentration and time dependent. These results clearly demonstrated an effect of SFN in inducing growth arrest and apoptosis in ovarian carcinoma cell lines. Chaudhuri et al . investigated the effects of sulforaphane on Akt signal transduction pathway. Both total Akt protein and active phosphorylated levels of Akt and phosphoinositide 3-kinase were significantly decreased in sulforaphane-treated ovarian cancer cell lines. Utilizing gene expression profile analysis, Bryant et al . showed SFN treatment resulted in G1 cell cycle arrest through down modulation of RB phosphorylation and by protecting the RB-E2F-1 complex. Conclusions : SFN induced growth arrest and cell death in ovarian cancer cells in G1 cell cycle arrest. The Akt pathway was identified as the possible target for SFN. SFN suppresses growth of ovarian cancer cells in vitro by modulating cell cycle regulatory proteins and by enhancing apoptosis. Inhibition of retinoblastoma (RB) phosphorylation and reduction in levels of free E2F-1 appear to play an important role in ovarian cancer growth arrest, migration, and invasion.
Pseudo-analytical solutions for stochastic options pricing using Monte Carlo simulation and Breeding PSO-trained neural networks

We introduce a novel methodology for pricing options which uses a particle swarm trained neural network to approximate the solution of a stochastic pricing model. The performance of the network is compared to the analytical solution for European call options and the errors shown statistically comparable to Monte Carlo pricing. The work provides a proof of concept that can be extended to more complex options for which no analytical solutions exist, the pricing method presented here delivering results several orders of magnitude faster than the Monte Carlo pricing method used by default in the financial industry.
Removal of methylene blue from aqueous solutions with natural olive pomace modified with ultrasounds and acid

Removal of methylene blue (MB) from aqueous solution by raw olive pomace (ROP) which is a waste of industrial olive oil and olive pomace modified with ultrasounds and acid (MOP) has been investigated. It was found that the data for ROP and MOP were well fit to the Freundlich isotherm model (R equal to 0.864 and 0.834, respectively). As a result; it was determined that raw olive pomace can be used for the removal of methylene blue dye (KF = 10.08 mg/g(dm/mg)) and modified olive pomace had high adsorption capacity for MB (KF = 73.08 mg/g(dm/mg)).
Occupational risk factors for carpal tunnel syndrome

Carpal tunnel syndrome (CTS) is a peripheral compressioninduced neuropathy and currently the most frequently diagnosed upper extremity musculoskeletal disorder [1,2]. CTS is characterized by pain and paresthesia on the palmar-radial aspect of the hand. Risk factors for CTS are forceful use of the hand, repetitive motion, position of the hand, and vibration [3]. Interest in CTS persists because it is the most common upper level compressive neuropathy resulting in considerable cost to all parties, workers, employers, insurers and as such its etiology is often debated.
Cathodal tDCS of the Left Posterior Parietal Cortex Increases Proprioceptive Drift

ABSTRACT In aiming movements the limb position drifts away from the defined target after some trials without visual feedback, a phenomenon defined as proprioceptive drift (PD). There are no studies investigating the association between the posterior parietal cortex (PPC) and PD in aiming movements. Therefore, cathodal and sham transcranial direct current stimulation (tDCS) were applied to the left PPC concomitantly with the performance of movements with or without vision. Cathodal tDCS applied without vision produced a higher level of PD and higher rates of drift accumulation while it decreased peak velocity and maintained the number of error corrections, not affecting movement amplitude. The proprioceptive information seems to produce an effective reference to movement, but with PPC stimulation it causes a negative impact on position.
User acceptance of an app-based adherence intervention: Perspectives from patients taking oral anticancer medications

Background Widespread adoption by patients is imperative for the success of app-based interventions for enhancing adherence to oral anticancer medications. Patients' attitudes and beliefs should be evaluated to understand determinants of their acceptance and adoption of such interventions. Objective To identify factors that influence cancer patients' intention to adopt an app-based system for enhancing oral anticancer medication adherence. Methods This study was conducted as part of the usability evaluation of an app-based system for enhancing adherence. We followed the grounded theory approach employing audio-recorded face-to-face interviews for data collection from patients taking oral anticancer medications (n = 15) and caregivers of such patients (n = 3). Data analysis involved verbatim transcription of all interviews, coding of the transcripts and field notes, detailed memo writing, and constant comparative evaluation of emergent categories. Results A conceptual framework of facilitating and hindering factors for users' adoption intention for an oral anticancer medication adherence app was developed. Findings suggest that facing difficulties in maintaining adherence and patients' perceived superiority of the app over their current methods facilitate adoption intention. In contrast, having to pay, lack of language options and users' perception of low competence in using an app were the hindrance factors. Conclusion This study showed that adoption of adherence apps could be explained by technology acceptance constructs, such as performance expectancy. Adoption intention was also facilitated by patients perceived vulnerabilities in maintaining adherence to their medications, which was a health behaviour construct. Implementation of app-based programs should address patients' perceived vulnerabilities and relative advantage of the app over their current methods. Clinicians and app developers should also consider the financial, technological and language barriers for end users.
A Comparative Study of Proficiency in Speaking and Writing among EFL Learners in Saudi Arabia

Learning of English as a foreign language is an imperative reality in a world largely shrinking with the advent of various revolutions, both socio-political and economic. However, it is seen that foreign language acquisition, especially of English, leaves a great deal to be desired as the learners so far in the geographical area of our study, i.e., Saudi Arabia, have failed to achieve native like fluency with the current teaching-learning practices. This raises questions as to the policies adopted vis-a-vis curriculum, pedagogy and most importantly, the stage at which foreign language learning is introduced in Saudi Arabia. The current study has undertaken an in-depth review of the available literature, which is followed up with modern testing methods to arrive at conclusions. It witnesses a dichotomy between speaking and writing abilities of college level young learners. The trend is towards a higher score on writing-ability tests as compared to the oral language proficiency tests. Thus a major communicative drawback is faced by the ‘products’ of this system of education, and numerous causes and remedies are suggested herein.
Reciprocal Verbs as Collective Predicate Concepts

We present a new analysis of reciprocal verbs, supported by experimental evidence challenging previous proposals. In a relatively simple example of lexical reciprocity, A&B dated means the same as A dated B and B dated A. A long-standing puzzle concerns the relation between reciprocity of intransitive verbs like date and symmetry of the transitive entry: A dated B = B dated A. Some authors have conjectured that all reciprocal verbs are symmetric in this way. However, verbs like collide and hug are an outstanding challenge for this conjecture: sentences like A&B hug invite a reciprocal interpretation, but transitive hug is clearly not symmetric, as seen in “the drunkard hugged the lampost” 3 . Here we show that non-symmetric verbs like hug are only “pseudo-reciprocal”. Following a recent proposal by Winter, we argue that there is no logical rule connecting sentences like A&B hug to “symmetric situations” where A hugs B and B hugs A. Instead, we propose that verbs like hug and collide denote collective predicate concepts in the lexicon. The relation between the intransitive entry and the transitive entry is described using “soft” typicality preferences. Our results reveal two preferences for categorization with such collective concepts, which are typical though not logically necessary. This allows implementing our proposal using a standard threshold theory of categorization. 6
THE CHEMICAL DISTINCTION OF NATURAL FROM SYNTHETIC

The chemical characteristics of natural and synthetic emeralds were studied in order to identify differences that could be used to separate them from one another. Thirtyeight natural emeralds from 20 localities and 11 synthetic stones from six manufacturers (flux and hydrothermal growth processes) were analyzed by microprobe and X-ray fluorescence. The ' results revealed a complex collection of chemical constituents that reflect the different environments in which natural and synthetic emeralds form. The present study agrees with the limited number of analyses previously reported for both materials. Thus, a new method of distinguishing natural from synthetic emeralds is now available for use in gemology when more conventional methods prove inadequate.
Beliefs About Behavioral Determinants of Obesity in Appalachia, 2011-2014

The populations of many Appalachian communities have high rates of unhealthy body weight. This study aimed to identify differences in beliefs about obesity between Appalachians and non-Appalachians. Our analyses explored health beliefs and behaviors among US adults aged ≥18 (n = 14 451) who responded to the Health Information National Trends Survey (2011-2014), of whom 1015 (8%) resided within the 420 counties recognized as Appalachian by the Appalachian Regional Commission. Using weighted regression analyses and controlling for sociodemographic characteristics and general health, we determined that self-reported body mass index was higher among Appalachians than among non-Appalachians (B = 0.75, P = .03, 95% confidence interval, 0.08-1.47) and that Appalachians were less likely than non-Appalachians to believe that lifestyle factors were related to obesity (B = –0.37, P = .03, 95% confidence interval, –0.04 to –0.71). Results suggest that Appalachians may regard behavioral prevention differently from non-Appalachians, perhaps with less confidence in the effectiveness of certain behaviors to reduce obesity risk. Future research may determine whether such beliefs could complicate efforts to encourage healthy lifestyles throughout the region.
MALOCCLUSION IN LEBANESE ORTHODONTIC PATIENTS: AN EPIDEMIOLOGIC AND ANALYTIC STUDY

The recognition of malocclusion as an important problem in the public dental health services implies the need of carrying out epidemiologic studies and analysing the prevalence rates of malocclusion.

Induction of apoptosis in human breast cancer cell line MCF-7 by phytochemicals from Gmelina asiatica

Currently, breast cancer is the leading cause of cancer-related death in women. Therefore, there is an urgent need to develop alternative therapeutic measures against this deadly disease. Many components from dietary or medicinal plants have been identified that possess substantial chemopreventive properties. India has unique plant varieties yet to be studied for anticancer components. Therefore, cytotoxicity activity and the mechanism of cell death exhibited by the extracts prepared from Gmelina asiatica, in human breast cancer MCF-7cells was investigated. The MCF-7 cells were seeded in 96-well culture plates in the presence and absence of different concentrations of extracts of G. asiatica to determine their anticancer effects using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Mechanism of cell death was evaluated by chromatin condensation using Hoest staining and morphological changes with the use of a contrast microscope. Plant extracts of G. asiatica were observed to induce apoptosis of MCF-7 cells as evidenced by MTT-cell proliferation assay, cell-morphological changes and chromatin condensation. The cytotoxicity of the chloroform extract was greater than other extracts of G. asiatica. The results of the present investigation is the first report on the potential anticancer activity of G. asiatica extracts and its possible mechanism of action on cancer cell proliferation in breast cancer MCF-7 cell lines.
