The Relationship Between Internet Addiction and Depression in the Iranian Users: A Systematic Review and Meta-analysis

Background and aims: Internet is one of the new technologies whose users are increasing, and internetaddiction is defined as the excessive use of internet. One of the factors that influence internet addictionis depression. The purpose of our study was to investigate the relationship between internet addictionand depression in Iranian users using meta-analysis.Methods: In our systematic review and meta-analysis, a total of 10 articles in Persian and English,published in local and international journals between 2008 and 2014 were selected through searchingin PubMed, Scopus, Google Scholar, SID, Magiran, Medlib, and Irandoc databases, and the informationwere analyzed using a method of meta-analysis (random effects model). I-square test was used toexamine heterogeneity. Data were analyzed by STATA version 11.2. Results: There were significant correlations between internet addiction and depression (P < 0.05). Hence the mean risk differentiating criteria were estimated to be 0.55 (95% CI: 0.14 to 0.96). Subgroupanalysis showed that the value of a university student was 0.46 (95% CI: 0.04 to 0.88) and of a highschool student was 1.12 (95% CI: 0.90 to 1.34). Conclusion: Our results indicated positive significant correlation between internet addiction anddepression in adolescents and young adults in Iranian users. There was a positive correlation betweeninternet addiction and depression as one of the most important psychological disorders. This issuerequires further attention and study.
GEOCHEMISTRY OF HORNBLENDE ALTERATION IN PLIOCENE RED BEDS, BAJA CALIFORNIA, MEXICO

The chemical and mineralogical changes that have taken place during intrastratal alteration of hornblende in Pliocene red beds of Baja California, Mexico, were determined by electron-probe microanalysis and X-ray diffraction studies. The hornblende has altered to iron-rich montmorillonite, and thin sections show that this clay ultimately forms hematite-stained matrix. The alteration involves loss of iron, alkalis, alkaline earths, and probably silica. The authigenic clay shows progressive decrease in iron content outward from the decomposing hornblende, indicating selective removal from the clay by intrastratal leaching. The authigenic clay is therefore an important source of iron for hematite pigment, particularly in the matrix of these red beds.
Transanal total mesorectal excision: single center study on risk factors for major complications

Purpose Transanal total mesorectal excision (TaTME) as a novel surgical approach for mid and low rectal cancer has gained significant research interest in recent years. The main objective of this study is to identify the risk factors associated with major complications after TaTME and evaluate the perioperative clinical outcomes. Methods A retrospective analysis was performed on the clinical data of patients with mid-to-low rectal cancer who underwent TaTME surgery and were admitted to the First Affiliated Hospital of Xiamen University from January 2018 to May 2023. Univariate and multivariate regression methods were employed to analyze the risk factors influencing the occurrence of major complications (Clavien-Dindo III-V). Results This study included a total of 179 eligible cases, with no perioperative deaths. The overall incidence of early complications was 25.1%, with a rate of 10.1% for mild complications and 15.0% for major complications. The postoperative anastomotic leakage rate within 30 days was 6.7%. Multivariate analysis demonstrated that male (P=0.030), pathological T ≥ 3 (P=0.018) and manual anastomosis (P=0.009) were independent risk factors for the development of major complications after surgery. Conclusion In this study, the incidence of early complications and anastomotic leakage rate in TaTME were both relatively low. Male, pathological T stage ≥ 3 and manual anastomosis were independent risk factors for the occurrence of major complications in a cohort of patients with mid and low rectal cancer undergoing TaTME.
LIVER CANCER: APPROACHING A PERSONALIZED CARE

: In the last decades, the understanding and knowledge regarding the intrahepatic cholangiocarcinoma (iCCA) and hepatocellular carcinoma (HCC) has been improved. Scientific research has made it possible to diagnose the liver cancer at the molecular level and provide optimal treatment to the patients to a maximum extent. The initial step, which is considered a landmark for future liver cancer management, was the discovery of TP53 hotspot mutation. In a nutshell, while decades ago the field of liver cancer was perplexing with grim perspectives, limited clinical data and research trials, it has now evolved into a competitive field with multiple advancements, research work and trials based evidence at a constant rate. Positive outcomes in preventive approaches, eliminating risk factors, understanding molecular mechanism, and better treatment chemistry will further increase the status of this field, and it might will exclude liver cancer from top 5 cancer killers.
Prevalence of attention-deficit hyperactivity disorder in older adults in the Netherlands

Background Little is known about the prevalence of attention-deficit hyperactivity disorder (ADHD) among older adults. Aims To estimate the prevalence of the syndromatic and symptomatic DSM-IV ADHD diagnosis in older adults in The Netherlands. Method Data were used from the Longitudinal Aging Study Amsterdam (LASA). At baseline, 1494 participants were screened with an ADHD questionnaire and in 231 respondents a structured diagnostic interview was administered. The weighted prevalence of ADHD was calculated. Results The estimated prevalence rate of syndromatic ADHD in older adults was 2.8%; for symptomatic ADHD the rate was 4.2%. Younger elderly adults (60–70 years) reported significantly more ADHD symptoms than older elderly adults (71–94 years). Conclusions This is the first epidemiological study on ADHD in older persons. With a prevalence of 2.8% the study demonstrates that ADHD does not fade or disappear in adulthood and that it is a topic very much worthy of further study.
Wine Tourism as a Centripetal Force in the Development of Rural Tourism

Purpose – The paper aims to explore the significance of wine tourism for the rural tourism development in the Republic of Croatia and its intensity as the centripetal force of this development. In their efforts to advance rural tourism, wine-growing regions vastly rely on wine tourism.Methodology – Based on the applied comparison, induction and deduction methods, the paper proposes measures which are expected to facilitate the wine tourism development and thus increase wine sales, and even more importantly, increase the demand for rural tourism products.Findings – Wine tourism should gain special significance as an increasingly interesting component of the rural tourism product within the Croatian tourism, especially in terms of creating experiences and atmosphere for tourists during their stay in a certain rural tourism destination. Wine tourism is positioned as an attractiveness factor for rural destinations as well as a powerful centripetal force through well-designed marketing efforts. This way significant synergistic effects can be achieved in the combined rural and wine tourism development. In the strategic sense, this also means combining complementary tourist attractions in a way that coordination, cooperation and partnership between different tourism entities bring about maximum effects in rural tourism operations.Contribution – The paper's originality is based on the claim that wine tourism should not be based solely on wine tasting and selling; rather, it should be linked in with gastronomic, natural, historical, entertainment and all other attractions in a particular rural destination. It is exactly this element that Croatian wine tourism is seriously lacking, mostly due to the fact that there are no destination management agents therein.
Relations Between Earthquake Magnitude and Fault Rupture Dimensions: How Regionally Variable Are They?

Data on subsurface rupture dimensions and seismic moments have been gathered for earthquakes in New Zealand, screened for data quality, and analyzed along with the multiregion rupture area data of Hanks and Bakun (2002). Regression analyses have been carried out for relations among magnitude and rupture length (subsurface), width, area, slip, and aspect ratio. Statistical comparisons show that there are significant differences between the regressions of New Zealand and multiregion data. The New Zealand relations among magnitude, area, and displacement are linear; those among magnitude, subsurface rupture length, and width are bilinear; whereas those between magnitude and rupture aspect ratio L / W are trilinear. The magnitudes predicted from rupture subsurface lengths, widths, or areas by multiregion relations are about 0.4 units smaller than those obtained from relations based on New Zealand data. The multiregion relations predict ruptures that are untenably large for New Zealand on the basis of structural and other evidence. Separate regressions were carried out for the California, China, and Japan subsets of the multiregion data, and it was found that there were statistically significant differences between New Zealand and California, New Zealand and Japan, New Zealand and China, and Japan and California. The respective contributions of rupture area and mean displacement to seismic moment are very different in New Zealand from those in California, Japan, and China, suggesting that rupture styles differ with geological region in a manner yet to be appropriately defined. Thus, multiregion relations are a poor approximation of the New Zealand data and perhaps also of the data of other regions where geological conditions differ substantially from the multiregion average.
Design of Wideband Asymmetric Doherty Power Amplifier Using a New Phase Compensation Technique

This article proposes a new phase compensation technique to expand the operating bandwidth of an asymmetric Doherty power amplifier (ADPA). Its operation principle is to increase the solution space of network parameters, thereby contributing to the broadband solvability of network parameters. The article provides a general method for solving network parameters in theory and numerical solutions for each network parameter. To verify the theory, a simple current source model simulates the load modulation process. The results show that this new compensation technique has consistent performance with the load modulation process of traditional ADPA at a similar parameter solution region. This technique can greatly expand the applicability of the network and allow for a more flexible design of ADPA. Furthermore, this theory was validated by designing a broadband ADPA of 1.7–2.7-GHz. The experimental results show that the saturation output power range is 46.9 dBm–48.5 dBm, with a saturation gain between 6 dB–9.3 dB and a corresponding saturation efficiency of 44%–69%. The efficiency is between 37%–65% at 6 dB back-off and 44%–52% at 9 dB back-off.
Visitors’ Perception of Theme Park Crowding and Behavioral Consequences

Since tourism is viewed as being a fast-growing industry, researchers are keen to investigate the negative impacts brought by an increasing number of visitors. As one of the derived social impacts, crowding has been proven to have a negative effect on tourists’ visiting experience. Thus, this study aims to understand tourists’ perception of crowding and its subsequent effect on their loyalty. A theme park in China called China Dinosaur Land, located in Jiangsu Province, is selected as the research site and 296 valid questionnaires are collected from the visitors. The results illustrate that psychological states, such as perceived crowding, emotional response, and coping behavior are much more complex than the study initially proposes; therefore, the hypotheses of the study are amended according to the research results.
Validation and Psychometric Properties of the Visual Analogical Fitness Perception Scale for Adolescents

Physical fitness (PF) is considered a highly relevant indicator for the healthy growth and development of children and adolescents, crucial stages where lifestyles and behaviors are established. Self-perceived fitness scales are quick and easy to use tools, allowing students to know and monitor fitness. The aim of the study was to show the factor structure and validity of the Visual Analogical Fitness Perception Scale for Adolescents (FP VAS A), a scale aimed at assessing self-perception of PF in adolescents. Reliability tests were used, as well as exploratory and confirmatory factor analyses. The results show a single-factor structure for the scale with high reliability (Cronbach's alpha = 0.80-0.90) and good and exceptional goodness-of-fit indices, composed of 4 items, eliminating the item of self-perception of flexibility for not meeting the criteria of factor loading (>0.60) and communality (>0.30). In conclusion, a cheap, simple and fast tool is shown. Applicable to the educational field in relation to Physical Education (PE), for the self-monitoring of PF by students and to encourage self-elaboration of physical activity (PA) plans. Keywords: physical fitness; physical activity; FP VAS A; validation; reliability; adolescents; physical education.
Familial Hypercholesterolemia: A Literature Review of the Pathophysiology and Current and Novel Treatments

Familial hypercholesterolemia (FH) is a genetically transmitted disorder. It shows an autosomal dominant mode of inheritance. It is a metabolic disorder. Mutation in chromosome 19 leads to this disorder. Chromosome 19 codes data for low-density lipoprotein (LDL) receptor (LDLR). LDLR either reduces increased LDL levels from the circulation or maintains a normal level of LDL. It precipitates the risk of cardiovascular disease at an early age. Characteristic features of FH are elevated levels of LDL in the blood because of sudden changes in LDLR, which causes a decrease in the clearance of LDL from the blood. Plaque gets deposited in the lumen of the arteries, called atherosclerosis, which occurs at an early young age. If both genes are affected then it is homozygous FH (HoFH); such a case is very rare. When a single gene is affected then that condition is known as heterozygous FH (HeFH). HoFH comes up with more severe cardiac disease than HeFH at an early age. The major cause of FH is a mutation in the LDLR gene while other causes include mutation in various genes like apolipoprotein B (apo B), proprotein convertase subtilisin/kexin type 9 (PCSK9), LDLR adaptor protein 1 (LDLRAP 1). In order to prevent cardiovascular crises due to FH, it must be diagnosed early and treated effectively. With increasing research and advances in medical sciences, many kinds of current and novel therapies are emerging that aim to reduce the level of LDL in blood.
Comparative Study of Gaussian Dispersion Formulas within the Polyphemus Platform: Evaluation with Prairie Grass and Kincaid Experiments

This paper details a number of existing formulations used in Gaussian models in a clear and usable way, and provides a comparison within a single framework—the Gaussian plume and puff models of the air quality modeling system Polyphemus. The emphasis is made on the comparison between 1) the parameterizations to compute the standard deviations and 2) the plume rise schemes. The Gaussian formulas are first described and theoretically compared. Their evaluation is then ensured by comparison with the observations as well as with several well-known Gaussian and computational fluid dynamics model performances. The model results compare well to the other Gaussian models for two of the three parameterizations for standard deviations, Briggs's and similarity theory, while Doury's shows a tendency to underestimate the concentrations because of a large horizontal spread. The results with the Kincaid experiment point out the sensitivity to the plume rise scheme and the importance of an accurate modeling of the plume interactions with the inversion layer. Using three parameterizations for the standard deviations and the same number of plume rise schemes, the authors were able to highlight a large variability in the model outputs.
Production and Characterization of Polyhydroxyalkanoate from Lignin Derivatives by Pandoraea sp. ISTKB

The present study investigates polyhydroxyalkanoate (PHA) production from lignin and its derivatives by a previously reported lignin-degrading bacterial strain Pandoraea sp. ISTKB. PHA production was screened by fluorescence microscopy and flow cytometry using a Nile red stain. PHA and biomass accumulation, while screening, was found to be maximum on 4-hydroxybenzoic acid followed by p-coumaric acid, vanillic acid, 2,6-dimethoxyphenol, and kraft lignin after 96 h. Monomer composition was analyzed by gas chromatography–mass spectrometry (GC–MS) and was followed by Fourier transform infrared and 1H NMR analysis, indicating PHA to be a copolymer of P(hydroxybutyrate-co-hydroxyvalerate). Genomic analysis of Pandoraea sp. ISTKB also complemented the results of GC–MS and NMR, and the relevant genes responsible for the synthesis of small chain length PHA were discovered in the genome. Process parameters were optimized by response surface methodology for enhanced production of PHA and biomass on 4-hydroxybenzoate. Optimization results showed 30 and 66% increase in the biomass and PHA production, respectively. The results obtained were promising and indicated that if lignin is depolymerized into low-molecular-weight intermediates, then it can easily be utilized and converted into value-added products like PHA by microbes.
Height-diameter allometry of tropical forest trees

Abstract. Tropical tree height-diameter (H:D) relationships may vary by forest type and region making large-scale estimates of above-ground biomass subject to bias if they ignore these differences in stem allometry. We have therefore developed a new global tropical forest database consisting of 39 955 concurrent H and D measurements encompassing 283 sites in 22 tropical countries. Utilising this database, our objectives were: 1. to determine if H:D relationships differ by geographic region and forest type (wet to dry forests, including zones of tension where forest and savanna overlap). 2. to ascertain if the H:D relationship is modulated by climate and/or forest structural characteristics (e.g. stand-level basal area, A). 3. to develop H:D allometric equations and evaluate biases to reduce error in future local-to-global estimates of tropical forest biomass. Annual precipitation coefficient of variation (PV), dry season length (SD), and mean annual air temperature (TA) emerged as key drivers of variation in H:D relationships at the pantropical and region scales. Vegetation structure also played a role with trees in forests of a high A being, on average, taller at any given D. After the effects of environment and forest structure are taken into account, two main regional groups can be identified. Forests in Asia, Africa and the Guyana Shield all have, on average, similar H:D relationships, but with trees in the forests of much of the Amazon Basin and tropical Australia typically being shorter at any given D than their counterparts elsewhere. The region-environment-structure model with the lowest Akaike's information criterion and lowest deviation estimated stand-level H across all plots to within amedian −2.7 to 0.9% of the true value. Some of the plot-to-plot variability in H:D relationships not accounted for by this model could be attributed to variations in soil physical conditions. Other things being equal, trees tend to be more slender in the absence of soil physical constraints, especially at smaller D. Pantropical and continental-level models provided less robust estimates of H, especially when the roles of climate and stand structure in modulating H:D allometry were not simultaneously taken into account.

Recibido: Noviembre 10, 2013. Aceptado: Junio 8, 2014. RESUMEN Introducción. El plasma rico en factores de crecimiento (PRGF) es un derivado de las plaquetas, empleado por aplicación directa en lesiones, para favorecer la regeneración y cicatrización de tejidos duros y blandos, incluyendo la osteoconducción, osteoinducción y osteogénesis. El objetivo del estudio fue utilizar una nueva técnica de aplicación de PRGF como alternativa terapéutica para disminuir el tiempo de recuperación después de traumatismos que impliquen fracturas. Material y métodos. Se aplicó PRGF por infiltración intralesional, procesado con la técnica descrita por Anitua y The Biotechnology Institute (BTI) durante la reducción cerrada y ferulización con yeso en fracturas tibiales en conejos Nueva Zelanda, reproducidas conforme a los modelos experimentales de Ashhurst (1982) y MacDonald (1988). Se realizaron cortes histológicos con recuento celular a 7, 15 y 21 días para comparación de resultados con el grupo control. Resultados. Los resultados fueron analizados mediante la prueba t para medias de dos muestras emparejadas con un nivel de significancia de 0.05%. En el cálculo estadístico t para osteoclastos, se encontró un valor de -2.2360, para osteoblastos 2.4419 y para osteocitos 0.8209 en comparación con el valor crítico t de 2.0150, encontrando diferencias significativas para las dos primeras mediciones. Conclusiones. Se observó incremento en la actividad osteoblástica y disminución en la osteoclástica después de la aplicación de PRGF en el grupo experimental, por lo que se concluye que la aplicación del plasma por infiltración intralesional reduce el tiempo de reparación de fracturas durante la reducción cerrada.
Open innovation: effects from external knowledge sources on abandoned innovation projects

Purpose Innovation projects are often risky and costly. But not all innovation projects lead to commercialisation; some are abandoned, and these abandoned innovation projects can be classified as a waste of resources. Therefore, this paper studies the influence of different external sources and a firm’s decision to abandon an innovation project. The purpose of this paper is to provide a broader understanding of abandoned projects. Design/methodology/approach The data applied are quantitative data and the empirical background is the Danish Innovation Survey 2009. The sample consists of Danish manufacturing firms with ten employees or more (n=840). The results are based on logistic regression analysis. Findings Results reveal that firms should consider that the involvement of customers can lead them to abandon innovation projects. However, if firms combine customers with universities, it will decrease the likelihood of innovation projects being abandoned. A more in-depth analysis shows that the involvement of customers from “Europe” (countries in Europe excluding Denmark) and the “US” leads to innovation projects being abandoned while customers from “other countries” (the rest of the world, including China and India) have the opposite effect. Originality/value The contribution is to the limited literature on abandoned innovation projects by suggesting that the type of external sources is a significant factor in firms’ decisions to abandon innovation projects. The paper identifies that the involvement of certain external sources leads firms to decide to abandon innovation projects, and that the country of origin of the external sources is an important criterion to consider in relation to a firm’s decision to abandon innovation projects.
AGENCY FOR TOXIC SUBSTANCES AND DISEASE REGISTRY

Activity Snapshot Backyard soils near a former pesticide facility in Norwood, Ohio, were found to be contaminated with arsenic. ATSDR’s state grantee recommended that the U.S. Environmental Protection Agency (EPA) remove the contaminated soil. EPA initiated and completed a timecritical removal action. ATSDR’s grantee reviewed soil sampling results following the removal to confirm that soil no longer posed a public health threat for children in the area.
