The aim of this research is to investigate the effect of different pin geometries, the ratio of shoulder diameter to pin diameter, and advancing speed on the mechanical and microstructural properties of the specimens fabricated from 6061 aluminum sheet by friction stir processing. Cylindrical, frustum and prisms with triangular section (in three sizes), square and hexagonal cross-sections pins were prepared. The diameter of the shoulder was considered 18 and the diameter of the peripheral circle of all the pins was considered 6 mm. Advancing speeds of 14, 20, and 28 mm/min and rotational speed of 1000 rpm were considered. The smallest grain size was obtained using a pin with square cross-section. As the advancing speed increased, the average grain size decreased and its lowest value was observed at the advancing speed of 28 mm/min. In addition, the best mechanical properties were observed in the specimens fabricated by square cross-section pin and frustum pin. As the advancing speed increased, the ultimate strength of all specimens and the yield stress of most specimens increased. The highest hardness was observed in the specimens fabricated by square cross-section pin and the lowest hardness was observed using cylindrical pin. Also, in specimens fabricated by triangular cross-section pins, by decreasing the ratio of the shoulder diameter to the pin diameter, the ultimate strength and hardness increased and the elongation decreased.

Key Clinical Message Recently spontaneous tension pneumomediastinum (STM), were reported as infrequent complications in coronavirus disease 2019 (COVID‐19) patients but pneumothorax (PT), and subcutaneous emphysema (SE) are more frequently seen in COVID‐19 patients. PT and SE may present after PTM in COVID‐19. The aim of this presentation is to show the complications of STM in an Iranian patients with COVID‐19 disease with PT and SE, who were hospitalized in Arya hospital, Rasht, Iran. For 3 months, we followed these patients and their condition was good. STM are uncommon complications in COVID‐19 patients and were reported frequently in male patients. Early diagnosis and treatment could save the patients as these complications are related to poor prognosis and prolonged hospitalization. Patients with mild COVID‐19 and mild pulmonary damage may have a favorable outcome.

In this paper, deformations and energy absorption capacities of thin-walled tubes with different section geometries (circle, square, rectangle, hexagon and triangle) under quasi-static in-plane loading are investigated. The tubes have the same material properties, mass, volume, lengths and average section area and the loading conditions are similar for all of the specimens. In order to investigate the behaviour of the tubes, more than 100 tests are carried out and numerical simulations are performed. The numerical results are in good agreement with experimental data and show that the section geometry has an important effect on energy absorption capacity so that the circular and square sections have the least and the most capability of energy absorption, respectively. Furthermore, for a specific tube, the absorbed energy increases with the wall thickness. The first peak load in load-displacement curves has the greatest and the smallest values for rectangular and circular sections, respectively.

Abstract Objective This study was performed in Razi Hospital, Rasht, Iran, between March 2016 and August 2018 on a population of chronic obstructive pulmonary disease (COPD) patients (56 as COPD exacerbation group and 56 as COPD stable group). Study variables include age, sex, occupation, body mass index (BMI), cigarette consumption, duration of COPD, annual hospitalization, dyspnea, glycated hemoglobin (HbA1c), FEV1, and FEV1/FVC indices. Result The mean age of the participants was 63.92 ± 10.75 years. There was a significant difference in the hospitalization between the patients with both exacerbation and normal state of COPD (P ≤ 0.001). HbA1c in the patients with exacerbation of COPD was significantly higher than stable status (P = 0.001). Logistic regression showed that HbA1c levels and hospitalization were predictors of exacerbation of COPD. HbA1c levels were statistically significant in terms of hospitalization in patients with COPD exacerbation. There was a significant difference between the HbA1c levels and MMRC in patients with COPD. The percentage of HbA1c was associated with exacerbation of COPD and HbA1c is a good predictor of disease severity in patients with COPD. It also shows that patients with COPD exacerbation and severe COPD are at the higher risk of hyperglycemia.

Genetics has been found to have a prominent role in autism and therefore pharmacogenetics may guide us to a better management of this disorder. Given the importance of Renin-Angiotensin System (RAS) in the function of the brain and its possible association with autism, genetic variations of RAS may influence response to autism treatment. In this study, 83 autistic children were enrolled (3 to 12 years of age). Degree of autism was confirmed by the DSM-V criteria and response to treatment was measured according to Aberrant Behavior Checklist (ABC) scale at baseline, 4 and 12 weeks of risperidone therapy. Polymorphisms (ACE I/D, rs4343 and rs4291) were determined by PCR-RFLP. Our results indicate the positive role of long term therapy in autism (12 weeks vs 4 weeks). The highest response rate in ACE ID gene was in the DD genetic variant at both 4 and 12 weeks of treatment. For the ACE A2350G gene, all genetic variants did not respond well to treatment at 4 weeks, however at 12 weeks, positive response was dominant in the AG genetic variant. Highest response rate in the ACE A240T gene belonged to the AT variant at both 4 and 12 weeks of treatment. However, our results indicate no significant association between ACE gene polymorphisms and response to risperidone therapy in autistic children based on ABC scaling. In conclusion, this study does not support the hypothesis of involvement of RAS genetics in response to risperidone in autistic children.

In this project, two types of treated and untreated alumina nanoparticles with different weight percentages (wt%) of 0.5, 1 and 3% were mixed with polycarbonate matrix; then, the impact ballistic properties of the nano-composite targets made from them were investigated. Three types of projectile noses -cylindrical, hemispherical, and conical, each with the same mass of 5.88\;gr -- were used in the ballistic tests. The results highlighted that ballistic limit velocities were improved by increasing the percentage of alumina nanoparticles and the treatment process; changing the projectile's nose geometry from conical to blunt nose increases the ballistic limit velocity, and ultimately, by increasing the initial velocity of conical and hemispherical nosed projectiles, the failure mechanism of the targets changed from dishing to petalling; whereas for the cylindrical projectile, the failure mode was always plugging.

Background: Sexually transmitted infections (STIs) are one the most common infections in the world. Among them, anogenital warts and gonorrhea infections are a significant group of STIs. We conducted this research to evaluate the prevalence of anogenital warts and gonorrhea infection and their related aspects in Iran. Still, it has a lot to know about its prevalence, trends, and risk factors. Methods: In this cross-sectional study, 1064 patients voluntarily referred from a marriage counseling center to the physicians in our center to evaluate STIs were enrolled in this study. All participants completed a data collection form about their sex, age, lifetime number of sexual partners, high-risk behaviors, and history of prior gonorrhea infection. They were also evaluated for anogenital warts by physical examination. The data were analyzed by SPSS 24 with Chi-square test, independent t-test, and logistic regression analysis. P-value Results: The number of participants with current anogenital warts was 9.2% (11.9% in men and 3.5% in women). 1.1% of the participants had a documented prior gonorrhea infection, and all of these cases were men. After logistic regression analysis, there was a significant relationship between anogenital warts and gonorrhea infection and male gender (P=0.03). Also, there was a meaningful relationship between these diseases and the higher number of lifetime sexual partners (P=0.001). Conclusions: Male sex and having more lifetime sexual partners are the risk factors for getting anogenital warts and gonorrhea infection.

Abstract In this pandemic SARS-CoV-2 crisis, any attempt to contain and eliminate the virus will also stop its spread and consequently decrease the risk of severe illness and death. While ozone treatment has been suggested as an effective disinfection process, no precise mechanism of action has been previously reported. This study aimed to further investigate the effect of ozone treatment on SARS-CoV-2. Therefore, virus collected from nasopharyngeal and oropharyngeal swab and sputum samples from symptomatic patients was exposed to ozone for different exposure times. The virus morphology and structure were monitored and analyzed through Atomic Force Microscopy (AFM), Transmission Electron Microscopy (TEM), Atomic Absorption Spectroscopy (AAS), and ATR-FTIR. The obtained results showed that ozone treatment not only unsettles the virus morphology but also alters the virus proteins’ structure and conformation through amino acid disturbance and Zn ion release from the virus non-structural proteins. These results could provide a clearer pathway for virus elimination and therapeutics preparation.

Transcorrelated methods provide an efficient way of partially transferring the description of electronic correlations from the ground-state wave function directly into the underlying Hamiltonian. In particular, Dobrautz et al. [Phys. Rev. B 99, 075119 (2019)2469-995010.1103/PhysRevB.99.075119] have demonstrated that the use of momentum-space representation, combined with a nonunitary similarity transformation, results in a Hubbard Hamiltonian that possesses a significantly more “compact” ground-state wave function, dominated by a single Slater determinant. This compactness/single-reference character greatly facilitates electronic structure calculations. As a consequence, however, the Hamiltonian becomes non-Hermitian, posing problems for quantum algorithms based on the variational principle. We overcome these limitations with the Ansatz-based quantum imaginary-time evolution algorithm and apply the transcorrelated method in the context of digital quantum computing. We demonstrate that this approach enables up to four orders of magnitude more accurate and compact solutions in various instances of the Hubbard model at intermediate interaction strength (U/t=4), enabling the use of shallower quantum circuits for wave-function Ansätzes. In addition, we propose a more efficient implementation of the quantum imaginary-time evolution algorithm in quantum circuits that is tailored to non-Hermitian problems. To validate our approach, we perform hardware experiments on the ibmq_lima quantum computer. Our work paves the way for the use of exact transcorrelated methods for the simulations of ab initio systems on quantum computers.

The discovery of superconductivity in hole-doped infinite-layer NdNiO2 — a transition metal (TM) oxide that is both isostructural and isoelectronic to cuprate superconductors—has lead to renewed enthusiasm in the hope of understanding the origin of unconventional superconductivity. Here, we investigate the electron-removal states in infinite-layered Ni1+ oxide, NdNiO2, which mimics hole doping, with the state-of-the-art many-body multireference quantum chemistry methods. From the analysis of the many-body wavefunction we find that the hole-doped d8 ground state of NdNiO2 is very different from the d8 ground state in isostructural cuprate analog CaCuO2, although the parent d9 ground states are for the most part identical. We show that the doped hole in NdNiO2 mainly localizes on the Ni 3dx2−y2 orbital to form a closed-shell singlet, and this singlet configuration contributes to ∼40% of the wavefunction. In contrast, in CaCuO2 the Zhang-Rice singlet configurations contribute to ∼65% of the wavefunction. With the help of the quantum information concept of entanglement entropy, we quantify the different types of electronic correlations in the nickelate and cuprate compounds, and find that the dynamic radial-type correlations within the Ni d manifold are persistent in hole-doped NdNiO2. As a result, the d8 multiplet effects are stronger and the additional hole foot-print is more three-dimensional in NdNiO2. Our analysis shows that the most commonly used three-band Hubbard model employed to express the doped scenario in cuprates represents ∼90% of the d8 wavefunction for CaCuO2, but such a model grossly approximates the d8 wavefunction for NdNiO2 as it only stands for ∼60% of the wavefunction.

Background: Obstructive sleep apnea (OSA) is the most common sleep-realted respiratory disorder. It is frequently comorbid with cardiovascular, cerebrovascular, and metabolic diseases and is commonly observed in populations with these comorbidities. Investigators aimed to assess the effect of OSA on glycemic control in patients with diabetes. Methods: In this cross-sectional study, 266 adult patients with diabetes mellitus (DM) attending the outpatient endocrinology clinic at the Guilan University of Medical Sciences were enrolled. Patients completed a checklist that included demographic characteristics, factors, and laboratory results in addition to Berlin and STOP-BANG questionnaires to evaluate the risk of OSA. Data were analyzed by independent t-test, Mann–Whitney U test, and Chi-squared or Fisher's exact tests using the Statistical Package for the Social Sciences (SPSS) version 17. Results: A total of 266 patients with DM were enrolled in this study (34.6% males, mean age 47.00 ± 19.04 years). Based on the Berlin Questionnaire, 38.6% of all participants were at high risk of developing OSA. Based on the STOP-BANG Questionnaire (SBQ), 45.1% were at moderate and high risks. Additionally, this questionnaire showed a significant difference between low and moderate-to-severe groups regarding sex, age, body mass index (BMI), neck size, other chronic diseases, types of DM, use of insulin, Berlin Questionnaire, fasting blood sugar (FBS), and mean HbA1c. Conclusions: Based on the SBQ, our results indicated a significant relationship between OSA and glycemic control according to mean HbA1c and FBS. Therefore, by controlling the OSA, we may find a way to acheieve better glycemic control in diabetic patients.

Objectives The aim of this study was to evaluate whether the waist circumference of patients with chronic obstructive pulmonary disease (COPD), had an impact on lung function. Methods There were 180 patients with COPD recruited into this prospective cross-sectional study. The age, weight, body mass index and waist circumference (WC) were measured. Spirometry parameters including forced vital capacity (FVC), and forced expiratory volume in the first second (FEV1), were measured and FEV1/FVC calculated. Results The mean FEV1/FVC in both normal weight and overweight patients, did not statistically significantly correlate with WC. The COPD assessment test, positively correlated with WC ( p = 0.031). A positive correlation with body mass index ( p < 0.001), smoking ( p = 0.027), and global initiative for chronic obstructive lung disease score ( p = 0.009), were observed to positively associate with WC. WC, age, C-reactive protein, duration of disease, and gender (male), were observed to be statistically significant risk factors for the severity of COPD. Conclusion WC was not observed to impact upon lung function in this study but it was a predictive factor for COPD severity in patients.

The biological materials such as potato tissue are made up of thin-walled, liquid-filled foam-like parenchyma cells. The sample preparation for scanning electron microscopy (SEM) by standard fixation, critical point drying (CPD) and freeze-drying result in shrinkage of cell walls. The hexamethyldisilazane (HMDS) as a time-saving and inexpensive chemical drying was used for sample preparation. However, the effect of HMDS drying on potato microstructure for SEM has not been investigated. This study compares 12 different preparation techniques of potato tissue to determine the best preservation of cellular structures by image analysis. Image analysis is a quantitative method for measuring the tissue microstructural features includes such as cell area, cell perimeter and cell roundness. Air drying and freeze-drying significantly altered the tissue dimensions (P

This review focuses on the role of gallium (Ga) nanoparticles (NPs) to enhance phagosome maturation into the Mycobacteriumtuberculosis-infected macrophage and the role of magnetic iron NPs as nanocarriers of antituberculosis drugs. The literature shows that silver (Ag) and zinc oxide (ZnO) NPs with dimensions less than 10 nm can penetrate directly through the macrophage bilayer membrane. Ag NPs increase the permeability membrane by motiving the aggregation of proteins in the periplasmic space and forming nano-sized pores. ZnO NPs can interact with the membrane of M. tuberculosis, which leads to the formation of surface pores and the release of intracellular nucleotides. The colloidal Ag:ZnO mixture NPs with 1:1 ratio can eliminate M. tuberculosis and shows the lowest cytotoxicity effects on MCF-7 and THP-1 cell lines. Ag/ZnO nanocrystals are not able to kill M. tuberculosis alone ex-vivo. Hence, bimetallic gold (Au)/Ag NPs possessed high efficiency to inhibit M. tuberculosis in an ex-vivo THP-1 infection model. Co-delivery of mixed MeNPs into a polymeric carrier collaborated to selective uptake by macrophages through passive targeting, initial burst release of ions from the encapsulated metallic (Me) NPs, and eventually, reduction of MeNPs toxicity, and plays a pivotal role in increasing the antitubercular activity compared to use alone. In addition, Ga NPs can import drugs to the macrophage, inhibit M. tuberculosis growth, and reduce the inhibition of phagosome maturation. Magnetic encapsulated NPs exhibited good drug release properties and might be suitable as carriers of antituberculosis drugs.

In this paper, the collapse properties of aluminum cylindrical tubes that hole or curvature is created on their edges or their mid is studied in experimental and numerical methods. The tubes were put under axial impact of a rigid mass-block of 30.405 kg by an initial velocity of 6 or 7 m/s. In experimental exams, first the type of aluminum alloy and mechanical properties of tubes were determined, and then four samples in order to validating the numerical results were analyzed under Impact collapse. An explicit FE code, LS-Dyna, was used to implement numerical investigation and a total of 13 specimens were examined. In results and discussion it was found that in impact loading, creating hole and curvature in edge and mid of cylindrical shells while keeping energy, decreases maximum force significantly and increasing crush force efficiency. In general, by increasing the number of holes, the less maximum force and more crush force efficiency. It was observed that in impact loading, establishment of curvature at the edges, reduces the maximum force and absorption energy and raises the crush force efficiency so that by raising edge curvature radius, maximum force and absorption energy decrease but crush force efficiency increase. Finally samples with optimal performance for each type of perforated and curved edge energy absorbers were introduced. These absorbers can be an appropriate alternative for usually types.

Background: Nowadays, suicidal attempts of adolescents, which are done with different methods, have caused a great concern in communities. Thus, this study aimed at surveying the reasons of suicidal attempts leading to hospitalization. Methods: This was a case-control study conducted on 300 adolescents during 1 year. In this study, 150 adolescents younger than 18 years, who were hospitalized due to suicidal attempt and referred to Nemazi hospital, were selected. After the primary measures were done and the patients gained consciousness, they were asked to fill out a questionnaire on the factors affecting suicidal attempt. Another questionnaire containing similar questions was filled out by 150 age-matched adolescents, as the control group, who referred to Nemazi hospital for problems other than suicide. The patients with chronic or advanced disease were excluded. Data were analyzed in SPSS, Version 17, using t test, chi-square, and logistic regression tests. In this study, the role of religion and beliefs in suicidal attempts was investigated. Results: Comparison of the 2 groups revealed a significant relationship between suicidal attempt and factors such as sex (P value < 0.001), educational level (P value < 0.001), fathers’ addiction (P value < 0.001), and history of imprisonment (P value < 0.001), history of suicide in the friends and relatives (P value < 0.001), maternal marital status (P value < 0.02), religious beliefs (P value < 0.001), depression in parents (P value < 0.01) and in adolescents (< 0.001), place of living (P value < 0.001), and neonatal diseases (P value < 0.017). Odds ratio of factors with significant P values were as follows: Male gender: 4.7, history of imprisonment of the father: 2.86, history of addiction in the father and mother: 1.27 and 1.26, history of neonatal disease: 1.99, remarriage of the father and mother: 2.7 and 4.35, history of depression: 2.52, place of living: 2.02, and lack of belief in Islam decree about suicide: 1.85, and lack of religious belief: 3. 18. Conclusions: According to the results, special attention should be paid to family grounds. In this respect, the role of parents and instructors is highly important. Moreover, the preventive role of religion, especially Islam, in preventing suicide is essential.

We propose a streamlined combination of the transcorrelation (TC) and coupled cluster (CC) theory, which not only increases the convergence rate with respect to the basis set but also extends the applicability of the lowest-order CC approximations to strongly correlated systems. Using the three-dimensional uniform electron gas as a model for real periodic solids and highly accurate ground-state energies from the state-of-the-art quantum Monte Carlo methods as benchmark, we show that, with the correct physical insights incorporated, our TC-CC methods gain drastic improvements in accuracy compared with canonical CC methods, and the errors of our methods remain ±0.001 Hartree per electron (Ha/electron) across a wide range of densities. With the greatly improved efficiencies and the balanced and accurate performances at both low and high densities, our methods present great promise for applications on real solids with weak and strong correlations.

Background: There is no a comprehensive study on early-onset multiple sclerosis (EOMS) population on the role of well-known MS risk factors. Moreover, age at puberty and the critical window exposure to environmental risk factors is never investigated in neither adult nor pediatric MS population. Methods: A case-control study, including 97 patients with early-onset MS and 97 matched controls, was conducted in Isfahan Multiple Sclerosis Society. Information on age at puberty, gestational risk factors, environmental exposures, and past medical history was obtained from medical charts and interviews. Findings: In logistic regression model, every year of decreasing in pubertal onset in females and males was associated with 1.766 and 2.250 folds increase in risk of early-onset MS, respectively. In utero exposure to cigarette smoking was significantly associated with 2.33 (P = 0.010), and having smoker parents or passive smokers before puberty had 2.88 (P =0.006) fold in risk of early-onset MS. One hour less daily sun exposure increased the risk of early-onset MS as 2.007 folds (P < 0.001) after adjustment for age and sex. Conclusion: In utero and parental exposure to smoking as well as history of measles and appendectomy are risk factors for early-onset MS. Future studies should shed more light on the true interaction between pineal gland, gender, smoking, sunlight and other environmental and genetic risk factors in adult and pediatric MS population.

BACKGROUND:The high chances of getting latent tuberculosis infection (LTBI) among health care workers (HCWs) will an enormous problem in low and upper-middle-income countries. METHOD:Search strategies were done through both national and international databases include SID, Barakat knowledge network system, Irandoc, Magiran, Iranian national library, web of science, Scopus, PubMed/MEDLINE, OVID, EMBASE, the Cochrane library, and Google Scholar search engine. The Persian and the English languages were used as the filter in national and international databases, respectively. Medical Subject Headings (MeSH) terms was used to controlling comprehensive vocabulary. The search terms were conducted without time limitation till January 01, 2019. RESULTS:The prevalence of LTBI in Iranian's HCWs, based on the PPD test was 27.13% [CI95%: 18.64-37.7]. The highest prevalence of LTBI in Iranian's HCWs were estimated 41.4% [CI95%: 25.4-59.5] in the north, and 33.8% [CI95%: 21.1-49.3] in the west. The lowest prevalence of LTBI was evaluated 18.2% [CI95%: 3.4-58.2] in the south of Iran. The prevalence of LTBI in Iranian's HCWs who had work-experience more than 20 years old were estimated 20.49% [CI95%: 11-34.97]. In the PPD test, the prevalence of LTBI in Iranian's HCWs who had received the Bacille Calmette-Guérin (BCG) was estimated 15% [CI95%: 3.6-47.73]. While, in the QFT, the prevalence of LTBI in Iranian's HCWs in non-vaccinated was estimated 25.71% [CI95%: 13.96-42.49]. CONCLUSIONS:This meta-analysis shows the highest prevalence of LTBI in Iranian's HCWs in the north and the west probably due to neighboring countries like Azerbaijan and Iraq, respectively. It seems that Iranian's HCWs have not received the necessary training to prevent of TB. We also found that BCG was not able to protect Iranian's HCWs from TB infections, completely.

We study properties of the lowest energy states at nonzero total momentum (yrast states) of the Hubbard model for spin-1/2 fermions in the quantum ring configuration with attractive on-site interaction at low density. In the one-dimensional (1D) case we solve the Hubbard model using the Bethe ansatz, while for the crossover into the 2D regime we use the Full-Configuration-Interaction Quantum Monte Carlo method to obtain the yrast states for the spin-balanced Fermi system. We show how the yrast excitation spectrum changes from the 1D to the 2D regime and how pairing affects the yrast spectra. We also find signatures of fragmented condensation for certain yrast states usually associated with dark solitons.

Various studies have shown that genetic factors contribute substantially to the development and progression of diabetes. Renin-angiotensin system has long been proven to have a major role in cardiovascular physiology and pathology. Its major product Angiotensin II (Ang II) with pro oxidant properties has shown to predict the future risk of diabetes. Fluoxetine, a drug of choice in management of depression, was observed to reduce fasting blood sugar (FBS). In the present study, six common polymorphisms of genes encoding for RAS components were determined in DNAs extracted from venous blood of 100newly diagnosed depressed individuals taking 12 weeks of fluoxetine. Blood samples were collected prior and after the period of treatment in order to measure FBS. Our results indicate that carriers of GG genotype of ACE A2350G showed significantly lower FBS levels after fluoxetine treatment (P=0.043). On the other hand haplotype analysis designate a significant association between DTG carriers of ACE I/D, A-240T and A2350G (P=0.001) and reduced FBS levels. In conclusion, this study supports the hypothesis that RAS genetic variations affect blood glucose after a course of treatment in Iranian population with depression

Background: Bipolar Mood Disorder (BMD) is a type of mood disorder which is associated with various disabilities. The family members of the patients with BMD experience many difficulties and pressures during the periods of treatment, rehabilitation and recovery and their quality of life (QOL) is threatened. In the present study, we aimed to evaluate the effect of family-centered education on mental health and QOL of families with adolescents suffering from BMD. Methods: In this randomized controlled clinical trial performed on 40 families which were mostly mothers of the adolescents with BMD referred to the psychiatric clinics affiliated to Shiraz University of Medical Sciences during 2012-13.They were randomly assigned to intervention and control groups. Results: The results of single factor multivariate ANOVA/single-factor multivariate analysis of variance and Bonferroni post hoc tests showed that the interaction between the variables of group and time was significant (P

In this paper, the effect of tubes distance on the mechanical behavior and energy absorption characteristics of nested thin-walled tubes is investigated using LS-DYNA. Thin-walled cylindrical tubes made of aluminum and steel. Axial impact load is carried out and by increasing the distance between the tubes the absorbed energy is calculated. Finally, the optimum distance to maximize this parameter is determined. Results showed that aluminum tubes in both material models used in the analysis, in an almost identical and the same distance (about 4 to 5 mm) from each other had the highest amount of absorbed energy. Steel pipes in both material models, at different distances showed the highest amount of energy absorption, although the number of folds in different distances was the same. Furthermore, the overall crushing and behavior of the steel tubes were different than those of aluminum tubes.

A hyperbolic singularity in the wave function of s-wave interacting atoms is the root problem for any accurate numerical simulation. Here, we apply the transcorrelated method, whereby the wave-function singularity is explicitly described by a two-body Jastrow factor, and then folded into the Hamiltonian via a similarity transformation. The resulting nonsingular eigenfunctions are approximated by stochastic Fock-space diagonalization with energy errors scaling with 1/M in the number M of single-particle basis functions. The performance of the transcorrelated method is demonstrated on the example of strongly correlated fermions with unitary interactions. The current method provides the most accurate ground-state energies so far for three and four fermions in a rectangular box with periodic boundary conditions.

About 20 percent of people above 60 years old suffer from tinnitus though no definitive treatment has been found for it. Evaluation of electrical brain activity using Event-Related Potentials (ERPs) is one of the methods to investigate the underlying reasons of tinnitus perception. Previous studies using ERPs suggest that the precognitive memory in tinnitus groups is negatively affected in comparison to the normal hearing groups. In this study, cognitive memory has been assessed using visual and auditory P300 response with oddball paradigm. Fifteen chronic tinnitus subjects and six normal hearing subjects participated in the experiment. T-test with significance level of 0.05 was applied on amplitude and latency of auditory and visual P300 for all electroencephalography (EEG) channels separately to compare tinnitus and normal hearing groups where the tinnitus group showed meaningful lower amplitude of auditory P300 peak in three EEG channels.

Evidences suggest that besides the neurotransmitters contributing to the development of depression, renin-angiotensin system (RAS) may also have a substantial role. Certain polymorphisms of RAS are associated with over activity of RAS & depression. Considering that antidepressants reduce the actions of angiotensin II, the main product of RAS, this may come into mind that genetic polymorphisms of the mentioned system may affect the outcome of therapy in depressed patients.In the present study, 100 newly diagnosed depressed patients, according to DSM-IV criteria, were treated with 20 mg of fluoxetine for 8-12 weeks. Patients were categorized into responsive and non-responsive groups according to 50% reduction in symptoms. Genotype frequencies of angiotensin-converting enzyme (ACE) gene [ACE (I/D, A-240T and A2350G)] were then determined in DNAs extracted from venous blood of the patients using polymerase chain reaction–restriction fragment length polymorphism (PCR– RFLP) and PCR.Results indicate that polymorphisms studied and their haplotypes were not associated with better response to fluoxetine. However, a strong association between age and treatment in depressed Iranian patients was observed (P=0.001).In conclusion, unlike previous reports, this study does not support the hypothesis of special genotypes of RAS contributing to a better response to antidepressants in depressed patients.

Objective: Glutamate is considered a target for treating obsessive-compulsive disorder (OCD). The efficacy and safety of the nutritional supplement of N-Acetylcysteine (NAC) as an adjuvant to serotonin reuptake inhibitor (SSRI) for treating children and adolescents with OCD has never been examined. Methods: This was a 10-week randomized double-blind placebo-controlled clinical trial with 34 OCD outpatients. The patients received citalopram plus NAC or placebo. Yale-Brown Obsessive-Compulsive Scale (YBOCS) and Pediatric Quality of Life Inventory (PedsQL™) were used. Adverse effects were monitored. Results: YBOCS score was not different between the two groups at baseline, but the score was different between the two groups at the end of this trial (P

Objectives: To describe the executive function of patients with traumatic injury admitted to Rajaei hospital, Shiraz, Iran and to compare the executive function between normal individuals and those with Attention Deficit Hyperactivity Disorder (ADHD). Methods: This was a case control study being performed during a 6-month period during spring and summer of 2013 in Shiraz level I trauma center. We included all patients admitted during the study period with impression of traumatic injury with or without adult ADHD. The patients’ demographic factors were assessed through self-report questionnaire and executive functions by Wisconsin Card Sort Test (WCST) and Tower of London (TOL). Results were compared between normal individuals and those with ADHD. Results: Among 60 patients evaluated during the study period, with impression of traumatic injury, 29 fulfilled adult ADHD criteria and 31 were normal. The mean age of ADHD patients was 27.16±5.6 years and that of normal individuals was 26±3.4 years (p=0.330). There were no significant differences between two study groups regarding IQ (p=0.191) and education (p=0.396). Patients with ADHD had significantly poorer mean in executive functions in different parts of the test scoring system when compared to normal individuals. Conclusion: ADHD patients with traumatic injury had poor executive function compared to normal individuals. This might lead to poor inhibition, shifting and problem solving in this population.

Introduction: Immunology Department of Hormozgan University of Medical Sciences is responsible for teaching immunology in all affiliated medical colleges in Hormozgan province. It has been proved that educational environment plays an important role in teaching and learning process. The purpose of this study was to explore students' views toward learning environment exists in immunology educational setting in International Medical Campus of Qeshm, paramedical and dental Schools.

Results: There were significant differences between the DREEM mean scores of Medical (125.7±23.2), Medical Laboratory Science (136.1±13.5) and Dentistry (132.4±15.3) students. Regarding DREEM questionnaire subscales, "students’ perceptions of teachers” achieved highest and" students’ perceptions of atmosphere" achieved lowest Score in all disciplines. In most of the subscales, Medical Laboratory Science students rated higher and students of International Medical Campus of Qeshm rated lower than others. Conclusion: Students in all disciplines perceived educational environment of immunology setting as" good”. To enhance the learning environment to "very good” level, factors Influencing educational climate especially in International Branch of Qeshm should be considered and improved.

​Background and Objectives : Referral time of patients affects treatment course and its success rate. Quick diagnosis of malignant and pre-malignant lesions of oral cavity is of utmost importance. Therefore, this study was aimed to evaluate the correlation of individuals’ socioeconomic status and the patient chief complaint duration in patients with oral pathologic lesions referring to Tabriz dentistry school in the first half of 1391. Materials and Methods: In this study, 80 patients referring to Tabriz dentistry school were selected randomly according to the inclusion and exclusion criteria. Then, the pre-prepared form containing demographic and information about socioeconomic status was filled out for each patient. Collected data were analyzed using descriptive statistics (median) and Mann–Whitney, Kruskal-Wallis and Spearman correlation tests using SPSS 15. Results : The median time of chief complaint duration in males and females was 90 and 14.50 days respectively and the difference was significant (P=0.001). The chief complaint duration median in urban and rural residents was 15 and 105 days respectively and the difference was statistically significant (P Conclusion : Based on the findings of this study, patients who were in lower socioeconomic status, the time of visiting (length of complaints) was longer.

Objective: The aim of the present study was to investigate the epidemiology of psychiatric disorders in ‎children and adolescents in five provinces of Iran: Tehran, Shiraz, Isfahan, Tabriz and Mashhad.‎ Method: In the present study, we selected 9,636 children and adolescents aged 6-18 years through ‎multistage cluster random sampling method from Tehran, Shiraz, Isfahan, Tabriz and Mashhad. ‎We instructed the clinical psychologists to complete the Strengths and Difficulties Questionnaire ‎‎(SDQ) for the participants, and those who received a high score on SDQ, completed the Persian ‎version of Kiddie-SADS-Present and Lifetime Version (K-SADS-PL). We used descriptive ‎analysis and 95% confidence interval to investigate the relationship between scores of the K-‎SADS questionnaire and demographic factors‏. ‏We used one-way ANOVA to test the significant ‎differences among the disorders according to sex, age and province of residence.‎‎ Results: Based on the results, oppositional defiant disorder (ODD) (4.45%) had the highest prevalence of psychiatric ‎disorders in the five provinces and substance abuse and alcohol abuse (0%) had the lowest ‎prevalence. In addition, attention deficit hyperactivity disorder (ADHD) had the most ‎prevalence in boys (5.03%) and ODD had the most prevalence in ‎girls (4.05%). Among the three age groups, 6 to 9 year olds had the highest rates of ADHD ‎‎(5.69%); 10 to 14 and 15 to 18 year olds had the highest rates of ODD (4.32% and 4.37% ‎respectively). Among the five provinces, Tehran and Mashhad allocated the highest rates of ODD; Isfahan and Shiraz had the highest rates of ADHD; and Tabriz had the highest rates of social phobia.‎ Conclusion: The current study revealed that the overall frequency of psychiatric disorders based on Kiddie-‎SADS-Present and Lifetime Version (K-SADS-PL) was higher than a similar study. Moreover, in ‎this study, among the five provinces, Tehran and Mashhad allocated the highest rates of ODD; Isfahan and Shiraz had the highest rates of ADHD; and Tabriz had the highest rates of social phobia. Therefore, these percentage ‎of psychiatric disorders in Iran lead us toward a greater use of consultation and mental health ‎services‏.

BACKGROUND:Autism is a disease of complex nature with a significant genetic component. The importance of renin-angiotensin system (RAS) elements in cognition and behavior besides the interaction of angiotensin II (Ang II), the main product of angiotensin-converting enzyme (ACE), with neurotransmitters in CNS, especially dopamine, proposes the involvement of RAS in autism. Since the genetic architecture of autism has remained elusive, here we postulated that genetic variations in RAS are associated with autism. METHODS:Considering the relation between the three polymorphisms of ACE (I/D, rs4343 and rs4291) with the level of ACE activity, we have investigated this association with autism, in a case-control study. Genotype and allele frequencies of polymorphisms were determined in DNAs extracted from venous blood of 120 autistic patients and their age and sex-matched healthy controls, using polymerase chain reaction (PCR) and PCR-restriction fragment length polymorphism (PCR-RFLP) methods. RESULTS:There were strong associations between both DD genotype of ACE I/D and the D allele, with autism (P = 0.006, OR = 2.9, 95% CI = 1.64-5.13 and P = 0.006, OR = 2.18, 95% CI = 1.37-3.48 respectively). Furthermore, a significant association between the G allele of rs4343 and autism was observed (P = 0.006, OR = 1.84, 95%CI = 1.26-2.67). Moreover, haplotype analysis revealed an association between DTG haplotype and autism (P = 0.008). CONCLUSION:Our data suggests the involvement of RAS genetic diversity in increasing the risk of autism.

In research outputs both quality and quantity are of critical value and evaluation of both aspects is required for best evaluation. Several studies have worked on single or two-dimensional methods that provide the assessment of quality, quantity or both simultaneously in different branches of sciences, but none of them have played a role in a particular area of medicine. This study has been conducted to compare countries worldwide in the field of medical researches. Measuring both quality and quantity of researches is performed separately. In order to evaluate countries from both aspects of quantity and quality of research outputs, a modified form of the citation per publication (CPPm) and publication per population (PPPm) were used to make these indices comparable through different years and nations by normalizing the values according to the world average standards. When countries are ranked by CPPm, Iceland ranks the 1st with the score of 1.98, Faroe Islands and Gambia rank the 2nd and the 3rd with scores of 1.84 and 1.63, respectively. In PPPm Switzerland, Sweden and Denmark ranked the top three with scores of 13.34, 11.67 and 10.32, respectively. Iran ranked 71 in CPPm and 141 in PPPm. Ranking countries makes it possible to identify countries which have performed better in research outcomes by means of quality and quantity; thus, reforming policies can be taken into action to lower the waste of money, higher quality and quantity of outputs while providing helpful tip(s) for institutions to improve.

During his diagnostic evaluation, a computed tomographic scan was performed and with huge mass in the anterior mediastinum with extension to the left and right side of pleural space. With postero-lateral thoracotomy the huge mass was resected. The patient discharged with good condition.

Objective: To evaluate the frequency of different psychiatric disorders among 7 to 12 years old children in urban areas of Tehran. "nMethod: A sample of 799 children (6 to 11 years old) were selected from 250 clusters of the entire 22 municipality areas of Tehran using a multistage sampling method from 250 clusters from the entire 22 municipality areas of Tehran. . After responding to a Persian version of the Strengths and Difficulties Questionnaire (SDQ) parent-report form, the Persian version of Kiddie Schedule for Affective Disorders and Schizophrenia - Present and Lifetime (K-SADS-PL) was administered to 241 children and their families. The frequency of child psychological disorders was determined using the results of K-SADS-PL. "n Results:The overall frequency of any psychological disorders in the sample of children was 17.9 percent. Among the interviewed children childrenwho were interviewed, the most prevalent diagnoses were Attention-Deficit/ Hyperactivity Disorder (ADHD) (8.6 percent)8.6%, Oppositional Defiant Disorder (ODD) (7.3 percent)7.3%, and separation anxiety disorder (SAD) (5.9 percent)5.9%. There were not any statistically significant differences between sexes in the frequency of psychological disorders except enuresis that was more frequent in the boys and anorexia nervosa that was observed more frequently in the girls . "nConclusion:Higher frequency of ADHD and ODD and SAD among the studied children warrantswarrants more specific evaluation of frequency and possible causes of these high frequency rates. The frequency of psychological disorders in the studied children was comparable to the that of other studies.

"n Objective: "n "nThe aim of this report was to study the gender role on autismsymptoms distribution and severity in a clinical sample from Iran. Then, the results were compared with the published study from the same community population sample, Iran. "nMethod: The subjects of this retrospective study were a convenient clinical sample of the referrals of children with pervasive developmental disorders. The diagnosis was made according to DSM-IV diagnostic criteria. "nResults: "nMost of the subjects were boys. Boys were referred for evaluation more frequently than girls. The sample included 61 children and adolescents aged 2.1 to 15 years; of whom, 49 had autism. The mean age of children with autism was 7.2(SD=3.2) years. The mean of age, the diagnosis and severity of the symptoms were not related to gender . "n "n "nConclusion: Usually, those with severe cases of autism refer to clinics for treatment. Therefore, the clinical sample of children with autism is just the tip of the iceberg and they may not be the actual representative of community sample of children with autism. Preventive programs should be more focused on the screening and referring of inflected girls for service utilization .

"n Objective: "n Major depressive disorder is a severe disorder that has a significant impact on the psychological and social functioning of children and adolescents. Considering current limitations in the treatment of this disorder, the present study was performed to evaluate the efficacy of fluvoxamine in the treatment of children and adolescents with major depressive disorder. "nMethod: In an open trial, the efficacy of fluvoxamine (50-200 mg/d) on children and adolescents with major depressive disorder or dysthymic disorder was evaluated using the "Children's Depression Inventory", the "Hamilton Anxiety Rating Scale", the "Children - Global Assessment Scale", the "Clinical Global Impression Scale", and the "Drug Side Effect Questionnaire" at the beginning and 2, 4, and 8 weeks after the beginning of the treatment. The frequency of suicidal ideas was evaluated as well. "nResults: Treatment with fluvoxamine caused statistically significant improvement in all of the above scales. The frequency of suicidal ideas decreased from 88.9 percent to zero after 8 weeks. No significant side effects were observed. "nConclusion: Fluvoxamine can be used as a safe and effective drug in the treatment of major depressive disorder and dysthymic disorder of children and adolescents.

"n Objective: "n The aim of the present study was to determine the prevalence of different psychiatric disorders among 12 to 17 years old adolescents in urban areas of Tehran. "nMethod: In this study, 1105 adolescents (12 -17 years old) were selected from 250 clusters of the entire 22 municipality areas of Tehran using a multistage sampling method. After responding to the Farsi version of the Strengths and Difficulties Questionnaire self-report version, the Farsi version of the Kiddie Schedule for Affective Disorders and Schizophrenia - Present and Lifetime version (K-SADS-PL) was administered to 273 adolescents and their families. The prevalence of adolescent psychiatric disorders was determined using the results of K-SADS-PL. "nResults: There were not any statistically significant differences between the sexes in the frequency of psychiatric disorders except for ADHD which was observed more frequently in boys. The most prevalent psychiatric disorders were attention-deficit/hyperactivity disorder (ADHD), oppositional defiant disorder, depressive disorders and separation anxiety disorder. "nConclusion: The frequency of psychiatric disorders among the adolescents in Tehran's urban areas was comparable to the reports from other countries. However, using methods to deal with missing data makes these prevalence rates somehow higher.

"n "n "nObjective: "nSchool-based interventions (such as life skills training) have become the mainstay for prevention of some behavioral problems. This study was conducted to evaluate the efficacy of a social skills training program on a group of students who were in the first grade of high school in an urban area of Tehran, Iran "n "n "nMethod: "nIn a before-after study, a kind of social skill education program named Right Choices" was used for high school female students. The entire students of a class in a high school participated in the study. The students' age ranged from 14-16 years. All of the participants lived in an urban area. Demographic characteristics were recorded in a designed questionnaire and included the name, age, educational level of the students and their parents, and prior history of psychiatric and medical condition. The total problem score and each of the subscale scores of the students before and after the study were calculated and compared. "n "n "nResults: "nThe mean age of the 33 participants in the study whose SDQ answer sheets were completed was equal to 15.15±6.2 years (14 to 17 years). The mean total problem score of the participants in the beginning of the program was equal to 14.3±5. After the program, the students' total problem score and all of the subscale scores improved, however, the differences between pre- and post intervention scores were not statistically significant. "n "n "nConclusion: "nSocial skills training program may impact the problem behaviors of the adolescent girls.

"n "n "n Objective: This study was performed to evaluate the mental health status of 6 - 11 year-old children of Tehran in a community-based sample using the Persian version of the Strength and Difficulties Questionnaire (SDQ) Parent-report. "nMethod: Parents of 799 children (6 to 11 years old) were selected from 250 clusters of the entire 22 municipality areas of Tehran; they responded to 25 questions of the Persian version of SDQ parent-report form. The mean score in each subscale and the frequency of each symptom domains based on the Goodman's cutoff points, were determined. "nResults: The prevalence of symptom domain was relatively high. Among the studied children, 25.8% had total score equal to 17 or more. The most frequent problem domain was conduct. The studied boys had statistically significant higher mean scores in hyperactivity and peer problem subscales. "nConclusion: Frequency of all the problem symptom domains was high in children from different urban areas of Tehran. Further evaluation for the reason of such a high frequency is necessary.

Objective: The aim of the present study was to investigate the epidemiology of psychological problems in adolescents in five provinces of Tehran, Khorasan Razavi, Isfahan, East Azerbaijan and Fars in Iran. Methods: In the present cross-sectional and descriptive – analytical study, 5171 adolescents aged 12 to 17 years were selected through multistage cluster sampling method from Tehran, Isfahan, Fars, Khorasan Razavi and East Azarbaijan provinces. The self-report form of Strengths and Difficulties Questionnaire (SDQ) was used to obtain the demographic data of each adolescent. Descriptive analysis and 95% confidence interval were used to investigate the relationship between scores of the SDQ questionnaire and demographic factors. Result: Based on the results, the highest prevalence of psychological problems in the five provinces was related to conduct problems (24%), and the lowest prevalence was related to social problems (5.76%). Also, comparison of 95% confidence interval of prevalence of psychological probl ms between the two genders suggested a significant difference only in emotional problems of the self-report version of the SDQ between the two genders. The result revealed no significant difference in the psychological problems of the self-report version of the SDQ between the two age’s groups and between the middle and high school graduates (p≤0.05). Among the 5 provinces, Fars allocated the highest rates of conduct problems (28.4), hyperactivity problems (21.5%) and overall criterion problems (17.3%); Esfahan had the highest rates of emotional problems (9.1%) and problems with peers (8.1%); and Khorasan Razavi had the highest rates of social problems (7.6%). Conclusion: In this study, the highest prevalence of psychological problems in the five provinces was related to conduct problems, and the lowest prevalence was related to social problems. It was determined that girls have more emotional problems than boys. Also, no significant difference was found in the psychological problems of 12 to 14 and 15 to 17 ear old adolescents or between middle and high school graduates. In the current study, the prevalence of psychological problems in adolescents in the urban population in Fars province was higher than expected.
