WE sampled 139 specimen of Acipenser persicus and 103 Acipenser stellatus over the years 19984999 in five fishing zones of the southern Caspian Sea for heavy metal contamination assessment. Flame Atomic Absorption Spectrophotometery was used to determine contamination of the specimens with Zn, Cu, Cd, and Pb and cold vapor method for Hg. The mean age for A. persicus and A. stellatus was 17.6±2.6 years and 11.9±1.8 years, respectively. The mean concentrations of heavy metals assessed for dry weight of the muscle tissues and caviar in A. persicus were 26.9 and 65.9 µg/g for Zn, 1.8 and 4.2 µg/g for Cu, 0.61 and 0.111 µg/g for Pb and 0.61 and 0.005 µg/g for Cd. The wet weight concentration of Hg in the muscle tissue and caviar of the fish were 0.06 and 0.007 µg/g respectively. For A. stellatus we determined the mean concentration of heavy metals in dry weight of the muscle tissue and caviar to be 27.4 and 57.8 µg/g for Zn, 1.64 and 4.85 µg/g for Cu, 0.481 and 0.112 µg/g for Pb and 0.59 and 0.005 µg/g for Cd while the wet weight concentration of Hg were 0.05 and 0.008 µg/g. By international standards, the contamination of the muscle tissue and caviar samples with the heavy metals in the two sturgeon species are well below maximum allowable for human consumption.

OBJETIVO: Avaliar a prevalência cumulativa dos fatores de risco para a doença cardiovascular aterosclerótica numa amostra de adolescentes iranianos. MÉTODOS: Foi realizado um estudo transversal com 1000 meninas e 1000 meninos, com idade entre 11 e 18 anos, selecionados através de uma amostragem aleatória multietapas à base de conglomerados das áreas urbana e rural de três cidades iranianas. RESULTADOS: As taxas de prevalência de inatividade física, dislipidemia, tabagismo, pressão arterial alta e obesidade (índice de massa corporal >P95) foram 66,6, 23,7, 8,7, 5,7 e 2,2%, respectivamente. Dentre os indivíduos estudados, 79,1% apresentaram pelo menos um e 24,6% tiveram dois fatores de risco para doença cardiovascular. A prevalência de inatividade física foi significativamente menor entre os meninos que entre as meninas [53,9 contra 79,3%, respectivamente, OR IC95%, 0,44 (0,39-0,51)]. A prevalência de tabagismo foi maior nos meninos que nas meninas [13,1 contra 4,2%, respectivamente, OR IC95%, 3,4 (2,4-4,9)]. CONCLUSÃO: Considerando a alta prevalência de fatores de risco para doença cardiovascular em adolescentes, deve-se garantir intervenções que sejam adequadas à idade e sensíveis a aspectos culturais para que medidas preventivas possam ser tomadas em tempo hábil. OBJECTIVE: To evaluate the cumulative prevalence of atherosclerotic cardiovascular disease risk factors in a representative sample of Iranian adolescents. METHODS: The subjects of this cross-sectional study were 1,000 girls and 1,000 boys, ages 11-18 years, selected by multi stage-random cluster sampling from urban and rural areas of three cities in Iran. RESULTS: The prevalence of physical inactivity, dyslipidemia, smoking, high blood pressure and obesity (body mass index >95th percentile) were 66.6, 23.7, 8.7, 5.7 and 2.2%, respectively. Of subjects studied, 79.1% had at least one and 24.6% had two cardiovascular disease risk factors. The prevalence of physical inactivity was significantly lower in boys than girls [53.9 vs. 79.3%, respectively, OR 95%CI, 0.44 (0.39-0.51)]. The prevalence of smoking was higher in boys than girls [13.1 vs. 4.2%, respectively, OR 95%CI, 3.4 (2.4-4.9)]. CONCLUSION: Considering the high prevalence of cardiovascular disease risk factors in adolescents, age-appropriate and culturally sensitive interventions for lifestyle change are warranted, so that preventive measures can be taken in a timely manner.

- Abstract
Resumo Objetivo Avaliar o efeito da adição de sufentanil à bupivacaína hiperbárica na duração do bloqueio sensorial da raquianestesia em usuários crônicos de opioides em comparação com não adictos. Métodos Foram distribuídos em quatro grupos 60 pacientes agendados para cirurgia ortopédica sob raquianestesia: Grupo 1 (sem história de uso de ópio, recebeu bupivacaína hiperbárica intratecal juntamente com 1 mL de solução salina como placebo); Grupo 2 (sem história de uso de ópio, recebeu bupivacaína intratecal juntamente com 1 mL de sufentanil [5 μg]); Grupo 3 (com história de uso de ópio, recebeu bupivacaína intratecal juntamente com 1 mL de solução salina como placebo) e Grupo 4 (com história de uso de ópio, recebeu bupivacaína intratecal juntamente com 1 mL de sufentanil [5 μg]). O tempo de início e a duração dos bloqueios sensitivo e motor foram registrados. Resultados A duração do bloqueio sensorial no Grupo 3 foi de 120 ± 23,1 min, um tempo significativamente menor do que nos outros grupos (G1 = 148 ± 28,7, G2 = 144 ± 26,4, G4 = 139 ± 24,7, p = 0,007). A duração do bloqueio motor no Grupo 3 foi de 145 ± 30,0 min, um tempo significativamente menor do que nos outros grupos (G1 = 164 ± 36.0, G2 = 174 ± 26.8, G4 = 174 ± 24,9; p = 0,03). Conclusões A adição de 5 μg de sufentanil intratecal à bupivacaína hiperbárica em usuários crônicos de opioides aumenta a duração dos bloqueios sensorial e motor de forma equivalente ao bloqueio avaliado em não adictos. Objective The primary outcome of this study was to evaluate the effect of adding sufentanil to hyperbaric bupivacaine on duration of sensory blockade of spinal anesthesia in chronic opioid users in comparison with non‐addicts. Methods Sixty patients scheduled for orthopedic surgery under spinal anesthesia were allocated into four groups: group 1 (no history of opium use who received intrathecal hyperbaric bupivacaine along with 1 mL saline as placebo); group 2 (no history of opium use who received intrathecal bupivacaine along with 1 mL sufentanil [5 μg]); group 3 (positive history of opium use who received intrathecal bupivacaine along with 1 mL saline as placebo) and group 4 (positive history of opium use who received intrathecal bupivacaine along with 1 mL sufentanil [5 μg]). The onset time and duration of sensory and motor blockade were measured. Results The duration of sensory blockade in group 3 was 120 ± 23.1 min which was significantly less than other groups (G1 = 148 ± 28.7, G2 = 144 ± 26.4, G4 = 139 ± 24.7, p = 0.007). The duration of motor blockade in group 3 was 145 ± 30.0 min which was significantly less than other groups (G1 = 164 ± 36.0, G2 = 174 ± 26.8, G4 = 174 ± 24.9, p = 0.03). Conclusions Addition of 5 μg intrathecal sufentanil to hyperbaric bupivacaine in chronic opioid users lengthened the sensory and motor duration of blockade to be equivalent to blockade measured in non‐addicts.

- Abstract
Resumo Justificativa e objetivo a hemorragia no período pós‐operatório é de grande importância clínica e pode contribuir para o aumento da morbidade e mortalidade em pacientes submetidos à cirurgia de revascularização coronária. Nesse estudo prospectivo, randômico e duplo‐cego, avaliamos o efeito da administração profilática de concentrado de fibrinogênio sobre o sangramento após cirurgia de revascularização coronária. Métodos no total, 60 pacientes submetidos à cirurgia de revascularização coronária foram randomicamente divididos em dois grupos. Os pacientes do grupo fibrinogênio receberam 1 g de concentrado de fibrinogênio 30 minutos antes da operação, enquanto os doentes do grupo controle receberam placebo. Os volumes de sangramento no pós‐operatório, tempo de protrombina, tempo de tromboplastina parcial, INR, hemoglobina e hemoderivados transfundidos em ambos os grupos foram registrados. Um protocolo de conduta rigoroso para transfusão de hemácias foi usado em todos os pacientes. Resultados não houve diferenças significantes entre as infusões de concentrados de hemácias nos grupos estudados (1,0 ± 1,4 no grupo fibrinogênio e 1,3 ± 1,1 no grupo controle). O grupo fibrinogênio apresentou menos sangramento no pós‐operatório (477 ± 143 versus 703 ± 179, p = 0,0001). Quinze pacientes do grupo fibrinogênio e 21 do grupo controle precisaram de infusão de concentrado de hemácias no pós‐operatório ( p = 0,094). Evento trombótico não foi observado durante 72 h após a cirurgia. Conclusão profilaxia com fibrinogênio reduz o sangramento no período pós‐operatório de pacientes submetidos à revascularização coronária. Background and objectives Postoperative bleeding has a great clinical importance and can contribute to increased mortality and morbidity in patients undergoing coronary artery bypass graft surgery. In this prospective, randomized, double‐blind study, we evaluated the effect of prophylactic administration of fibrinogen concentrate on post‐coronary artery bypass graft surgery bleeding. Methods A total of 60 patients undergoing coronary artery bypass surgery were randomly divided into two groups. Patients in the fibrinogen group received 1 g of fibrinogen concentrate 30 min prior to the operation, while patients in the control group received placebo. Post‐operative bleeding volumes, prothrombin time, partial thromboplastin time, INR, hemoglobin and transfused blood products in both groups were recorded. A strict red blood cell transfusion protocol was used in all patients. Results There were no significant differences between intra‐operative packed red blood cells infusion in the studied groups (1.0 ± 1.4 in fibrinogen group, and 1.3 ± 1.1 in control group). Less postoperative bleeding was observed in the fibrinogen group (477 ± 143 versus 703 ± 179, p = 0.0001). Fifteen patients in the fibrinogen group and 21 in the control group required post‐op packed red blood cells infusion ( p = 0.094). No thrombotic event was observed through 72 h after surgery. Conclusion Prophylactic fibrinogen reduces post‐operative bleeding in patients undergoing coronary artery bypass graft. [ABSTRACT FROM AUTHOR]

Abstract Introduction Gross’s Emotion Regulation Questionnaire is one of the most widely-used and valid questionnaires for assessing emotion regulation strategies. The validity and reliability of the Persian version have not been determined and data on its psychometric properties are not available to Iranian mental health researchers. The purpose of this study was to determine the psychometric properties of the Emotion Regulation Questionnaire in Iranian students. Methodology In this cross-sectional study, 348 students (170 males and 178 females) were selected from Shahid Beheshti University of Medical Science and Tehran University of Medical Science. The following statistical procedures were conducted: correlation coefficients, factor analysis, Cronbach’s alpha, and independent t tests. Results The results showed that men use suppression more than women (T = -2.62, p = 0.009). Cronbach’s alpha coefficients were 0.76 for the cognitive reappraisal sub-scale and 0.72 for the suppression sub-scale (excluding question 9). Six questions related to the cognitive reappraisal factor explained 30.97% of emotion regulation variance, and 3 questions related to the suppression factor explained 22.59% of emotion regulation variance. Overall, these factors explained 53.5% of emotion regulation variance. There were significant correlations between suppression and difficulties in emotion regulation, trait anxiety, and affective control. Furthermore, there was a significant correlation between cognitive reappraisal and the Five-Facet Mindfulness Questionnaire. Conclusion The results indicate that the Persian version of the ERQ is a reliable and valid instrument that can be helpful for development of further important studies of emotional regulation.

Abstract Introduction Depression is one of the most important psychiatric disorders, and the rate of recurrence is high. The heavy cost burden of depression is probably due to treatment-resistant depression. The purpose of this study was to determine the effectiveness of mindfulness-based cognitive therapy (MBCT) in patients with treatment-resistant depression (TRD). Method The present study was a quasi-experimental study conducted with twenty-four patients with treatment-resistant depression. Participants were selected by purposive sampling and randomly assigned to two groups, an experimental group and a control group. The experimental group received MBCT and antidepressants, while the control group received antidepressants only. The Hamilton and Beck Depression Inventory, Self-Compassion Scale, Thought Rumination Scale, and Mindfulness Scale were administered. The treatment program was conducted in eight sessions; with a follow-up period of one month subsequent to treatment termination. Data were analyzed using descriptive statistics (mean and standard deviation) and inferential statistics (analysis of variance for repeated measures and Bonferroni’s post-hoc test). Results The results showed that MBCT significantly reduced depression and ruminative thinking in the experimental group and also improved mediators such as mindfulness and self-compassion. Patients maintained gains over the one month follow-up period (p < 0.01). Conclusion The present study provides additional evidence for the effectiveness of MBCT for TRD.

ABSTRACT This experiment was conducted to evaluate the effects of stocking density and climate region on performance, immunity, carcass characteristics, blood plasma, and economic parameters of the Ross strain of broiler chickens. The effects of four climates (mild and humid, semi-arid, alpine, and hot and dry) and four densities (10, 15, 17, and 20 chicks/m2) were studied as a completely randomized design with 4×4 factorial arrangement of treatments. The results showed that the density had a significant effect on feed intake and feed conversion ratio in the starter period and on body weight gain in the grower and the whole periods of the experiment. Moreover, both climate and density had a significant impact on economic performance (live weight, survival rate, production index, meat production/m2, and profitability). The mild and humid climate and the density of 17 chicks/m2 had the most economic benefit compared with other treatments. The climate type had a significant effect on the relative weights of the breast, wings, neck, proventriculus, and ileum. The effects of climate and density on glucose, triglyceride, very low-density lipoproteins (VLDL), high-density lipoproteins (HDL), LDL/low-density lipoproteins (HDL), total protein and globulin were significant. In addition, the effect of climate on the antibody titer against sheep red blood cells (except for immunoglobulin G on day 28) was significant.

Objective: Experiencing romantic love is an important part of individual development. Here, we investigated stability and change in romantic love and psychological correlates, including mood states, anxiety, and sleep, among Iranian adolescents over a period of 8 months. Method: Two hundred and one adolescents who had taken part in a previous study were contacted; 157 responded. Participants completed a questionnaire covering sociodemographic data, current state of love, and mood, including symptoms of depression, anxiety (state and trait), and hypomania. They also completed a sleep and activity log. Results: Of 64 participants formerly in love, 45 were still in love; of 86 participants not in love at baseline, 69 were still not in love (overall stability, 76%); 17 had fallen in love recently while 19 were no longer in love. Significant and important changes in mood and anxiety were observed in that experiencing romantic love was associated with higher anxiety scores. Hypomania scores increased in those newly in love, and decreased in those in a longer-lasting romantic relationship. Sleep and sleep-related variables were not associated with romantic love status. Conclusion: These findings suggest that, among Iranian adolescents, the state of love is fairly stable, and that love status seems to be associated with specific states of mood and anxiety.

ABSTRACT Taking into consideration that modeling and indicating relationship among traits and variables are among the most useful numerical techniques in the biological and botanical researches, and also undeniable impact of drought and salinity stresses, this research was implemented with the aim to consider change in relationship among the traits under separately drought and salinity stresses related to scarcely distributed medicinal plant called Christ thorn (Ziziphus spina-christi). A glass house experiment was implemented in controlled conditions at the College of Agriculture, Shiraz University, Shiraz, Iran. Five different water stress levels (irrigation at four, six, eight and 10 days intervals, compared to the unstressed control plants with every even days irrigation) and five salinity stress levels (0, 3.2, 6.4, 9.6 and 12.3 dS m-1) were separately induced on plants. Results of this study indicated that salinity and water stresses in addition to their destructive impact on cell and tissue compartment, can adverse and change the relationship among morphological and biochemical parameters in different ways. Cluster analysis could clearly separate traits into two groups under water stress while three groups under salinity stress. Principal component showed that this technique can accounted for a high variation among data under both water and salinity stresses so that it is possible to consider relationship among the traits using principal component in place of classic methods such as correlation coefficients. As result of principal component, it revealed that change in relationship among traits under different stresses is plausible.

Abstract Objective: The aim of this study was to evaluate the effect of displacement patterns of the molar teeth in response to different asymmetric headgear loading using 3D finite element method. Methods: A series of twenty-five facebow with different left vs. right outer bow length and different expansion of left vs. right were designed. The non-favored side (right side) was shortened at intervals of 10 mm, and favored side (left side) was expanded 10 degree greater than right side and 5 degree expansion were successively added. At the first phase, each side received 200-g load, implying the neck strap to displace toward shorter arm. At the second phase, a total of 400-g load was applied to the ends of the outer bow. Because of the neck strap displacement, the shorter arm received greater load than the left side, the magnitude of the applied force to each side depended on difference of left vs. right outer bow length and expansion. Results: All systems were effective in promoting asymmetric distal movement of the molars. However, the asymmetrical facebow with the 40 mm shortening and 25 degree expansion outer bow when unequal force applied could be used in asymmetric mechanics. Medial and occlusal displacing forces were observed in all systems. Conclusions: Both equal and unequal force application is effective for molar distalization. Expansion of the outer bow in the affected side and shortening of the outer bow in the normal side were effective to produced differential distal molar movement.

Objective: In Western countries, the prevalence of childhood trauma (CT) ranges from 15 to 25%. CT might be indirectly associated with lower parental socioeconomic status and educational attainments. The aims of this cross-sectional study were fourfold: to assess prevalence of CT in a large sample of Iranian children; to compare the Iranian prevalence rates with those of Western countries; to explore gender-specific patterns; and to explore possible socioeconomic predictors. Method: The sample comprised 608 children (mean age 11.49 years, 51.5% females). All completed the Farsi version of the Trauma Symptoms Checklist for Children. Additionally, parents reported on their current employment status and highest educational level. Results: Trauma symptoms were reported by 20 of 295 boys and 23 of 313 girls. The overall prevalence was 7.1%. Child-reported trauma symptoms were not associated with parents’ socioeconomic status or highest educational level. Compared to prevalence findings from U.S. national surveys (ranging from 15-25% of children and adolescents), the prevalence among 11- and 12-year-olds in the present study was considerably lower. Conclusions: The overall prevalence of reported trauma symptoms among a large sample of Iranian children was unrelated to parents’ socioeconomic status, and was lower than that reported in U.S. surveys.

Abstract Objective: The primary outcome of this study was to evaluate the effect of adding sufentanil to hyperbaric bupivacaine on duration of sensory blockade of spinal anesthesia in chronic opioid users in comparison with non-addicts. Methods: Sixty patients scheduled for orthopedic surgery under spinal anesthesia were allocated into four groups: group 1 (no history of opium use who received intrathecal hyperbaric bupivacaine along with 1 mL saline as placebo); group 2 (no history of opium use who received intrathecal bupivacaine along with 1 mL sufentanil [5 µg]); group 3 (positive history of opium use who received intrathecal bupivacaine along with 1 mL saline as placebo) and group 4 (positive history of opium use who received intrathecal bupivacaine along with 1 mL sufentanil [5 µg]). The onset time and duration of sensory and motor blockade were measured. Results: The duration of sensory blockade in group 3 was 120 ± 23.1 min which was significantly less than other groups (G1 = 148 ± 28.7, G2 = 144 ± 26.4, G4 = 139 ± 24.7, p = 0.007). The duration of motor blockade in group 3 was 145 ± 30.0 min which was significantly less than other groups (G1 = 164 ± 36.0, G2 = 174 ± 26.8, G4 = 174 ± 24.9, p = 0.03). Conclusions: Addition of 5 µg intrathecal sufentanil to hyperbaric bupivacaine in chronic opioid users lengthened the sensory and motor duration of blockade to be equivalent to blockade measured in non-addicts.

ABSTRACT Caper (Capparis spinosa) is used as multipurpose and adaptable plant which provides a valuable opportunity to enhance greenery in harsh climatic areas. This plant like the others is affected by drought and sodium chloride stresses as the most common abiotic stresses worldwide. This study was carried out to determine the interaction between drought and different ratios of sodium and calcium chloride on caper. Droughts stress were two levels of 100 and 75% of field capacity and were applied based on the daily weighting method of pots. Salt treatments were four different ratios of calcium chloride: sodium chloride (1:0, 1:1, 1:3, 1:5]. Treatments started when the plants were sown in the pots. Results indicated that higher ratios of calcium chloride than sodium chloride which caused salinity stress have destructive effect on water relationships and contents of the caper. This stress affected growth, morphological, and physiological function related traits in a negative way. Growth and other traits decreased under water deficit conditions. It seems that interaction between salinity and drought had the most destructive effect on this plant and decreasing its quality and quantity of its traits.

ABSTRACT Salinity is among the most common and severe abiotic stresses that drastically affects crop productivity all over the world. To evaluate the effect of salt stress on seed germination, early growth, antioxidant enzyme activity and ABA content of chicory ecotypes (Cichorium intybus), a factorial experiment was conducted at College of Agriculture, Shiraz University in 2014 based on completely randomized design with four replications. The treatments comprised five salinity levels (tap water, 3, 6, 9, 12 dS m-1) of sodium chloride on the ecotypes of Sefid Shiraz and Siyah Shiraz. The results showed that germination characteristics and primary seedling growth decreased in both ecotypes with increasing in salinity severity. The effects of salinity on radicle and plumule length as well as seedling weight were the same as its effects on seed germination. The effect of salt stress on antioxidant enzyme activity (especially catalase) and ABA content were significant which they were enhanced with increasing salinity level; the Siyah Shiraz ecotype performs better than the Sefid Shiraz under high salinity, as indicated by lower decrease in germination characteristics and primary growth and higher antioxidant enzyme activity as well as ABA content. These facts should be taken into consideration in the economic cultivation of this valuable horticultural and medicinal plant and this data would be useful for the crop breeding projects.

ABSTRACT Calotropis procera, Apocynaceae, is a wild perennial shrub that originated in the Persian deserts. It is known to provide key resources in degraded ecosystems to about 80 animal species. C. procera is regenerated by seed and produces lots of small seeds that are dispersed by wind; nonetheless, its density is very low. The purpose of this study is to estimate the cardinal temperatures including the base, optimum, and maximum temperatures of Calotropis procera looking at two different ecotypes in the Iranian desert. The germination behavior of C. procera seeds was tested at temperature regimens of 0, 5, 10, 15, 20, 25, 30, 35 and 40oC and was analyzed using linear regression models. The rate of germination increased between base and optimum thermal conditions, and decreased between optimum and maximum thermal conditions. The base, optimum and maximum temperatures for germination of C. procera seeds were estimated at 19.10, 30.75 and 47.80 oC for the Fars and 20.00, 31.82 and 49.69oC for the Zahedan desert, respectively. Temperature and germination were rated to determine the seeding dates of the C. procera. Overall, cardinal temperatures for germination were dependent on local climate characteristics for the range of adaptations in plant growth of the given species.

Objective: Whereas several studies have predicted academic achievement (AA) as a function of favorable cognitive factors and low negative emotional functioning (such as depression and anxiety), little is known about its associations with cognitive-emotional states of positive emotional functioning, such as social satisfaction. The present study sought to evaluate associations of AA with dimensions of negative and positive emotional functioning. Method: This cross-sectional study enrolled 275 students (mean age, 21.24 years; 66.1% females), who completed questionnaires covering sociodemographic parameters and AA scores, as well as measures of loneliness and depression (representing negative emotional functioning) and social satisfaction (representing positive emotional functioning). Results: Lower scores for negative and higher scores for positive emotional functioning were associated with higher AA scores. Multiple regression analysis showed that AA was predicted independently by both low negative and high positive emotional functioning. No gender differences were observed. Conclusions: The pattern of results observed in this study suggests that opposing dimensions of emotional functioning are independently related to AA. Students, educators, and health professionals dealing with students should focus both on increasing social satisfaction and on decreasing feelings of loneliness and depression.

The objective of this study was to evaluate associations between average lactation somatic cell counts (SCC) and herd management practices in an arid climate. A total of 38,530 average lactation SCC records for 10,216 Holstein cows gathered on 25 dairy farms from January 2009 to October 2012 in Isfahan (Iran) were analyzed. Average lactation SCC (cells × 1,000) was 250.79 ranging from 90.31 to 483.23 cells/mL across investigated farms. Herd-level management factors associated with average lactation SCC were determined separately using mixed linear models in the MIXED procedure with average lactation somatic cell score (SCS) included as the dependent variable. Some of the management practices associated with low average lactation SCS included sawdust combined with sand bedding, using automatic cup removers, disinfection of the teats by dipping into disinfectant, using washable towels for teat cleaning, free-stall barns, wet disposable tissue for udder washing, wearing gloves during milking and the use of humidifiers and shade. Lower-production herds and larger-size herds had lower average lactation somatic cell counts. Most herd management practices associated with average lactation SCC in dairy herds in the arid region of Isfahan are in agreement with most previous studies. However, different results are found for use of humidifier, bedding materials and herd size.

BACKGROUND AND OBJECTIVES: Postoperative bleeding has a great clinical importance and can contribute to increased mortality and morbidity in patients undergoing coronary artery bypass graft surgery. In this prospective, randomized, double-blind study, we evaluated the effect of prophylactic administration of fibrinogen concentrate on post-coronary artery bypass graft surgery bleeding. METHODS: A total of 60 patients undergoing coronary artery bypass surgery were randomly divided into two groups. Patients in the fibrinogen group received 1 g of fibrinogen concentrate 30 min prior to the operation, while patients in the control group received placebo. Post-operative bleeding volumes, prothrombin time, partial thromboplastin time, INR, hemoglobin and transfused blood products in both groups were recorded. A strict red blood cell transfusion protocol was used in all patients. RESULTS: There were no significant differences between intra-operative packed red blood cells infusion in the studied groups (1.0 ± 1.4 in fibrinogen group, and 1.3 ± 1.1 in control group). Less postoperative bleeding was observed in the fibrinogen group (477 ± 143 versus 703 ± 179, p = 0.0001). Fifteen patients in the fibrinogen group and 21 in the control group required post-op packed red blood cells infusion (p = 0.094). No thrombotic event was observed through 72 h after surgery. CONCLUSION: Prophylactic fibrinogen reduces post-operative bleeding in patients undergoing coronary artery bypass graft.

Success in educational settings is an ever-present wish. For EFL learners, writing ability is a highly favored but neglected skill. As opposed to IQ, Emotional Intelligence (EI) theory is increasingly characterized as contributing to students' ability to improve their achievement. In this study, the body of female BA sophomores of TEFL in Urmia University, (N = 47), within the age range of 18-25, was given a close look in terms of their EI. The students were first given Bar-On's Emotional Quotient Inventory (a Likert scale questionnaire) and were asked to respond to its items based on the relevance of the statements to themselves. Thereafter, the students were given a writing test and the resulting scores were correlated with their EI scores. The scoring of writing tasks was done analytically following pre-specified criteria. The writings were scored once by two raters, yielding an inter-rater reliability of 0. 8. Results obtained through Multiple Regression rendered a positive relationship between writing ability and emotional self-awareness, a subcategory of EI. This can create a room for highlighting emotions in one's educational lif

Using scaling methods, a single solution of Richards' equation (RE) will suffice for numerous specific cases of water flow in unsaturated soils. In this study, a new method is developed to scale RE for the soil water redistribution process. Two similarity conditions are required: similarity in the shape of the soil water content profiles as well as of the water flux density curves. An advantage of this method is that it is not restricted to a specific soil hydraulic model - hence, all such models can be applied to RE. To evaluate the proposed method, various soil textures and initial conditions were considered. After the RE was solved numerically using the HYDRUS-1D model, the solutions were scaled. The scaled soil water content profiles were nearly invariant for medium- and fine-textured soils when the soil profile was not deeply wetted. The textural range of the soils in which the similarity conditions are held decreases as the initial conditions deal with a deeply wetted profile. Thus, the scaling performance was poor in such a condition. This limitation was more pronounced in the coarse-textured soils. Based on the scaling method, a procedure is suggested by which the solution of RE for a specific case can be used to approximate solutions for many other cases. Such a procedure reduces complicated numerical calculations and provides additional opportunities for solving the highly nonlinear RE as in the case of unsaturated water flow in soils.

Abstract Introduction Multiple sclerosis (MS) is a chronic medical condition that attracts particular attention because of the high risks associated with it. MS patients suffer from medical problems, depression, anxiety, and reduced hopefulness. These issues can increase the severity of the disease and treatment resistance and reduce patients’ individual and social efficacy. Mindfulness-integrated cognitive behavior therapy (MICBT) is a new approach that is being applied in chronic diseases and can be used in combination with existing treatments. Therefore, the present study investigated the efficacy of MICBT in terms of anxiety, depression, and hope in MS patients. Methods A sample of 20 patients with MS was randomly selected at Shafa Hospital in Kerman City, Iran. Patients were then assigned to one of two groups of 10 people using a random number table. The experimental group received MICBT. The control group also received the same therapy after study completion. The assessment tools used in this study included the Beck Depression Inventory-Second Edition (BDI-II), Beck Anxiety Inventory (BAI), and Miller Hope Scale (MHS). Measurements were conducted at three stages: pre-test, post-test, and follow-up. For data analysis, means and standard deviations were calculated and one-way analysis of covariance was conducted using SPSS 24. Results Compared with controls, MICBT was effective for reducing depression (P < 0.001, F = 72.55), anxiety (P < 0.001, F = 100.75). Additionally, MICBT was effective in improving hope (P < 0.001, F = 45.36). Changes were maintained in the follow-up phase. Conclusion The MICBT affects depression, anxiety and hope of MS patients. Therefore, mental health professionals can benefit from the results obtained in the present study to reduce depression and anxiety and increase hope in this group of patients.
