- Abstract
It is well documented that sole application of potassium (K) or mycorrhizal fungi can alleviate heavy metal stress in plants. As an indicator of the efficient defense in the mycorrhizal fungi-plant system, glomalin synthesis in the rhizosphere can be determined. In this study, interactive effects of mycorrhizal fungi (MY) and K on glomalin content, heavy metal uptake and mycorrhizal properties of sunflower plants were examined with three soil K levels (0, 100, and 200 mg K kg−1 using K2SO4). The three levels of mycorrhization are: i) no mycorrhizal inoculation, ii) Rhizophagus irregularis inoculation, and iii) mixed mycorrhizal inoculum application. Joint application of potassium and mycorrhiza significantly increased the percentage of root colonization and easily extractable glomalin (EEG), showing 56% root colonization in the treatment of K100 + mixed mycorrhiza and 178 µg EEG g−1 in the treatment of K200 + mixed mycorrhiza. Joint application of MY and K significantly reduced the translocation of heavy metals to the shoot of the plants. The highest total uptake of Zn by plants per pot (2.01 mg pot −1) and Pb (0.78 mg pot −1) were found in non-mycorrhizal plants. The MY and K treatments also increased the chlorophyll content and leaf area index by 57%. This study concluded that application of potassium and mycorrhizal fungi enhanced glomalin production and increased plant resistance to heavy metal stress.

Background Children exposed to family poverty have been found to have higher morbidity and mortality rates, poorer mental health and cognitive outcomes and reduced life chances across a wide range of life domains. There is, however, very little known about the extent to which poverty is experienced by children over their early life course, particularly in community samples. This study tracks changes in family poverty and the main factors that predict family poverty (adverse life experiences) over a 30-year period since the birth of the study child. Methods Data are from a prospective, longitudinal, birth cohort study conducted in Brisbane, Australia. Consecutive families were recruited at the mothers’ first obstetrical visit at one of two major obstetrical hospitals in Brisbane. Data are available for 2087 families with complete data at the 30-year follow-up. Poverty was measured using family income at each time point (adjusted for inflation). Findings Poverty affects about 20% of families at any time point. It is common for families to move in and out of poverty, as their circumstances are affected by such adversities as unemployment and marital breakdown. Over the period of the study about half the families in the study experienced poverty on at least one occasion. Only a very small minority of families experienced persistent poverty over the 30-year duration of the study. Logistic regressions with time lag show that family poverty predicts subsequent adversities and adverse events predict subsequent poverty. Conclusions Experiences of poverty and adversity are common and may vary greatly over the child’s early life course. In assessing the health consequences of poverty, it is important to distinguish the timin

Application of nonlinear energy sink in annihilating self-excited oscillations of a slightly modified experimental and theoretical torsional vibration model of drill-string with real parameter values is studied in this article. Various configurations have been examined in order to procure steady-state responses in less time and expand the range of the existence of stable equilibria. Moreover, applied modification to the experimental model resulted in more realistic response. It is proven that attaching nonlinear energy sink to different components of a drill-string would help to acquire better responses and/or to improve applicability of the nonlinear energy sink.

- Abstract
Background: Leishmaniasis is a zoonotic disease and Iran is one of the ten countries with has the highest estimated cases of leishmaniasis. This study aimed to determine the time trend of cutaneous leishmaniasis (CL) incidence using the ARIMA model in Shahroud County, Semnan, Iran., Methods: In this study, 725 patients with leishmaniasis were selected in the Health Centers of Shahroud during 2009-2020. Demographic characteristics including; history of traveling, history of leishmaniasis, co-morbidity of other family members, history of treatment, underlying disease, and diagnostic measures were collected using the patients' information listed in the Health Ministry portal. The Box-Jenkins approach was applied to fit the SARIMA model for CL incidence from 2009 to 2020. All statistical analyses were done by using Minitab software version 14., Results: The mean age of patients was 28.2 ± 21.3 years. The highest and lowest annual incidence of leishmaniasis were in 2018 and 2017, respectively. The average ten-year incidence was 132 per 100,000 population. The highest and lowest incidence of the disease were 592 and 195 for 100,000 population in the years 2011 and 2017, respectively. The best model was SARIMA (3,1,1) (0,1,2)
4 (AIC: 324.3, BIC: 317.7 and RMSE: 0.167)., Conclusions: This study suggested that time series models would be useful tools for predicting cutaneous leishmaniasis incidence trends; therefore, the SARIMA model could be used in planning public health programs. It will predict the course of the disease in the coming years and run the solutions to reduce the cases of the disease., (© 2023. The Author(s).)- Published

- Abstract
Background: Schistosoma japonicum remains endemic in China and the Philippines. Substantial progress has been made in the control of Japonicum in both China and the Philippines. China is reaching elimination thanks to a concerted effort of control strategies. Mathematical modelling has been a key tool in the design of control strategies, in place of expensive randomised-controlled trials. We conducted a systematic review to investigate mathematical models of Japonicum control strategies in China and the Philippines., Methods: We conducted a systematic review on July 5, 2020, in four electronic bibliographic databases - PubMed, Web of Science, SCOPUS and Embase. Articles were screened for relevance and for meeting the inclusion criteria. Data extracted included authors, year of publication, year of data collection, setting and ecological context, objectives, control strategies, main findings, the form and content of the model including its background, type, representation of population dynamics, heterogeneity of hosts, simulation period, source of parameters, model validation and sensitivity analysis. Results After screening, 19 eligible papers were included in the systematic review. Seventeen considered control strategies in China and two in the Philippines. Two frameworks were identified; the mean-worm burden framework and the prevalence-based framework, the latter of which increasingly common. Most models considered human and bovine definitive hosts. There were mixed additional elements included in the models, such as alternative definitive hosts and the role of seasonality and weather. Models generally agreed upon the need for an integrated control strategy rather than reliance on mass drug administration alone to sustain reductions in prevalence., Conclusions: Mathematical modelling of Japonicum has converged from multiple approaches to modelling using the prevalence-based framework with human and bovine definitive hosts and find integrated control strategies to be most effective. Further research could investigate the role of other definitive hosts and model the effect of seasonal fluctuations in transmission., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 The Author(s).

- Abstract
Most cats and dogs entering Australian animal shelters and municipal facilities are classed as strays, typically from low socio-economic areas. Contemporary practices increasingly focus on proactively reducing the number of stray animals, which requires further understanding of factors associated with straying animals, including pet confinement. Australian cat and dog owners ( n = 2103) were surveyed to investigate attitudes towards four types of pet confinement and how these were influenced by social norms, demographics and concerns about pet quality of life and potential wildlife predation. Dog owners showed the strongest support for confining dogs to the owners' property whenever unsupervised (98% agreement) and less support for confining dogs inside the house at night (54% agreement), and only 23% believed dogs had a negative impact on wildlife. Cat owners showed the strongest support for confining cats inside the house at night (89% agreement). Cat owners' non-supportive attitudes towards cat confinement were partly because of higher concern for cat quality of life and lower concern about their cats' predation behaviours, compared to non-cat owners. The findings provide valuable information to inform more effective strategies to reduce stray animals which would reduce shelter admissions, euthanasia, costs, nuisance issues, potential wildlife predation and negative mental health impacts of euthanasia on staff. Strategies to reduce strays include assisting low-income pet owners to install effective fencing and programs to increase identification. Informing cat owners about bedtime feeding is recommended to assist with night containment, and providing high-intensity free sterilization of owned and semi-owned cats targeted to areas of high cat impoundments is also recommended., Competing Interests: The authors declare no conflict of interest.

- Abstract
The fate of antibiotics and their effects on plant growth may be changed by the application of fertilizers. The present study was carried out to investigate the effect of sulfadiazine (SDZ), rice husk compost (RHC), rice husk biochar (RHB), and mycorrhiza (MR) on the growth attributes of Iranian Echium amoenum Fisch & C.A. Mey. A greenhouse experiment as a completely randomized design with six treatments of bio/organic-fertilizers (no bio-fertilizer (NF), RHB, RHC, MR, RHB+MR, and RHC+MR) and three levels of SDZ application (0, 100, and 200 mg kg
-1 ) was performed for 7months with three replicates. Shoot and root SDZ concentrations were determined using high-pressure liquid chromatography-diode array detection (HPLC-DAD) instrumentation. The results revealed that the application of RHC, RHB, and MR had a significant impact on the reduction of the toxicity effects of SDZ on plant properties. The lowest values of growth parameters belonged to the 200 mg kg-1 of SDZ with no bio-fertilizers, while the highest growth parameters were observed in the treatments of RHB+MR, and RHC+MR with no SDZ application. Also, chlorophyll pigments content was affected by used treatments and the lowest rates of chlorophyll a (4.24), chlorophyll b (2.99), and carotenoids (2.88) were related to the 200 mg kg-1 of SDZ with no biofertilizers application. The co-application of bio-fertilizers and SDZ (at both levels of 100 and 200 mg kg-1 ) decreased SDZ uptake by both shoot and root in comparison with the control. The same results were obtained with macro (NPK) and micro (Fe, Zn, Cu, and Mn) nutrients uptake by the shoot in which the lowest values of nutrients uptake were observed in treatment of 200 mg kg-1 of SDZ with no bio-fertilizers. Furthermore, in the case of the effect of the used treatments on root colonization, the results showed that the lowest value (7.26%) belonged to the 200 mg kg-1 application of SDZ with no bio-fertilizers. Generally, this study demonstrated that bio-fertilizers could be considered as an effective strategy in controlling the negative effects of antibiotics on the growth properties and nutrients status of the plants grown in such contaminated soils., (Copyright © 2020 Elsevier Inc.

- Abstract
Although much available research indicates that intimate partner violence (IPV) is male perpetrated, growing recent evidence suggests a gender symmetry model of family violence. This article examines gender differences in IPV in current and prior relationships reported by young adults. Data comprised 2,060 young adults (62.1% females) who participated in the 30-year follow-up of the Mater Hospital and University of Queensland Study of Pregnancy (MUSP) in Brisbane, Australia. The Composite Abuse Scale was used to measure IPV during the last 12 months in the respondents' most recent relationship. Similar proportions of males and females reported leaving their prior relationships. Both males and females who were not currently in a relationship reported experiencing much higher rates of IPV than those who were in a relationship. There were no differences in the past experience of IPV between males and females who were not currently in a relationship, but males in a current relationship reported they experienced most forms of IPV more often than did females. IPV typically involves both male and female perpetrators and victims. It does appear that the majority of relationships involving higher rates of IPV were dissolved. IPV was more likely to have occurred in relationships that ended than in relationships that persisted. Males more often remain in an abusive relationship and report experiencing higher rates of IPV in their current relationships compared with females.

- Abstract
Poverty and socioeconomic disadvantage place demands on intimate relationships and provide fertile ground for disagreements and conflicts. It is not known whether poverty also leads to intimate partner violence (IPV). This study investigates the association between income and forms of IPV victimization for both males and females. We also examine whether income inequalities are related to IPV and whether the gender balance of household income contributes to IPV victimization. Data are from a cohort of 2,401 young offspring (60.3% females) who participated at the 30-year follow-up of the Mater-University of Queensland Study of Pregnancy in Brisbane, Australia. Participants completed questionnaires including their income details and the Composite Abuse Scale. Within low-income families, both partners experience higher levels of IPV. Females' income is not independently related to experiencing IPV either for females or males. Females and males experience a higher rate of IPV when the husband earns a low income. When considering partners' relative income, families in which both partners earned a low income experienced higher levels of almost all forms of IPV. Income (im)balance in which females earn more or partners both have higher income was less often associated with the experience OF IPV IPV appears to be mutually experienced in the setting of the poverty. Objective economic hardship and scarcity create a context which facilitates IPV for both partners in a relationship.

- Abstract
Purpose: The current longitudinal study examines the temporal association between different types of intimate partner violence (IPV) at early adulthood (21 years) and subsequent depression and anxiety disorders in young adulthood (30 years)., Methods: Participants were from the Mater-University of Queensland Study of Pregnancy. A cohort of 1529 was available for analysis. IPV was measured using the Composite Abuse Scale at 21 years. At the 21 and 30-year follow-ups, major depression disorder and anxiety disorders were measured using the Composite International Diagnostic Interview., Results: We found a temporal relationship between almost all forms of IPV at 21 years and females' new cases of major depression disorder at 30 years. This association was not found for females who had previously been diagnosed with depression disorder. IPV did not predict the onset of new anxiety disorders, but it had a robust association with anxiety disorders in females with a previous anxiety diagnosis. We observed no significant link between IPV and males' subsequent major depression disorder. Interestingly, the experience of emotional abuse was a robust predictor of new cases of anxiety disorders but only for males., Conclusion: Our results suggest the need for sex-specific and integrated interventions addressing both IPV and mental health problems simultaneously. IPV interventions should be informed by the extend to which pre-existing anxiety and depression may lead to different psychological responses to the IPV experience. Increased risk of anxiety disorders predicted by emotional abuse experienced by males challenges beliefs about invulnerability of men in the abusive relationships and demands further attention.

- Abstract
Aims: To examine the temporal association between the experience of different types of intimate partner violence (IPV) in early adulthood (21 years) and substance use disorders in young adulthood (30 years)., Design: Prospective birth cohort study using data from the Mater-University of Queensland Study of Pregnancy (MUSP)., Setting: Brisbane, Australia., Participants: A total of 1353 people (822 females and 531 males)., Measurements: IPV was measured using the Composite Abuse Scale (CAS) and alcohol, substance and nicotine use disorders were assessed using the Composite International Diagnostic Interview (CIDI)., Findings: In females, the experience of different forms of IPV at 21 years remained a robust risk factor for subsequent alcohol use disorder [adjusted odds ratios (aORs) ranged from 1.6 to 2.6 (all P < 0.05)], substance use disorder [aORs ranged from 2.1 to 4.0 (all P < 0.001)] and nicotine use disorder [aORs ranged from 2.0 to 2.4 (all P < 0.05)] at 30 years, even after controlling for antecedent substance disorders. However, in males only physical and emotional abuse (but not harassment) were significant in predicting alcohol use disorder [aORs ranged from 1.4 to 1.8 (all P < 0.05)] and drug use disorder [aORs ranged from 1.6 to 2.0 (all P < 0.05)] in the fully adjusted model., Conclusion: Intimate partner violence (IPV) in early adulthood is robustly associated with alcohol, substance and nicotine use disorders in women, whereas in men the association is clear for only some forms of IPV and types of disorder., (© 2019 Society for the Study of Addiction.)

- Abstract
There is some limited evidence of an association between maternal intimate partner victimization (IPV) and children's experience of maltreatment. Using data from a longitudinal study, we examine whether this relationship is independent of range of potential confounders including socio-economic, familial and psychological factors. Data were taken from the 14 and 30-year follow-ups of the Mater-University of Queensland Study of Pregnancy (MUSP) in Australia. A subsample of 2064 mothers and children (59.0% female) whose data on maternal IPV and child maltreatment was available, were analysed. In families with maternal IPV, two in five children reported being maltreated, compared to one in five children maltreated in families without maternal IPV. Except for sexual maltreatment which was consistently higher in female offspring, there was no gender differences in experiencing different types of maltreatment in families manifesting maternal IPV. Although both males and females were at increased risk of child maltreatment in families where mothers were victimized by their male partners, male children were more likely to be emotionally maltreated. The main associations were substantially independent of measured confounders, except for father's history of mental health problems which attenuated the association of maternal IPV victimization and male offspring's physical abuse. Our findings confirm that there is a robust association between maternal IPV and child maltreatment. Both maternal IPV victimization and child maltreatment co-occur in a household characterized by conflict and violence. Consequences of IPV go beyond the incident and influence all family members. Efforts to reduce child maltreatment may need to address the greater level of IPV associated with the cycle of family violence., (Copyright © 2018 Elsevier Ltd. All rights reserved.)

- Abstract
Background: This paper investigates gender differences in persistence of intimate partner violence (IPV), for those remaining or leaving an abusive relationship. We followed a sample of males and females to examine whether leaving an abusive partner may alter the continuity of victimization., Methods: Data were taken from the 21 and 30-year follow-ups of the Mater Hospital and University of Queensland Study of Pregnancy (MUSP) in Australia. A cohort of 1265 respondents, including 874 females and 391 males, completed a 21-item version of the Composite Abuse Scale., Results: We found proportionally similar rates of IPV victimization for males and females at both the 21 and 30 year follow-ups. Females who reported they had an abusive partner at the 21 year follow-up were more likely to subsequently change their partner than did males. Harassment and then emotional abuse appeared to have a stronger association for females leaving a partner. For males, a reported history of IPV was not significantly associated with leaving the partner. There was no significant association between leaving (or not) a previous abusive relationship and later victimization, either for male or female respondents., Conclusion: Changing a partner does not interrupt the continuity of victimization either for male or female respondents, and previous IPV victimization remained a determining factor of re-abuse, despite re-partnering.

- Abstract
Background: Child abuse is a significant public health and social problem worldwide. It can be described as a failure to provide care and protection for children by the parents or other caregivers. This study aimed at evaluating the effectiveness of psychosocial interventions in abused children and their families. Methods: This quasi-experimental study was conducted in the psychosocial support unit of a pediatric hospital in Bandar Abbas, Iran, from 2012 to 2013. The participants consisted of child abuse cases and their parents who referred to the psychosocial support unit to receive services. Services delivered in this unit included parenting skills training, psychiatric treatments, and supportive services. The effectiveness of the interventions was assessed with Child Abuse Questionnaire, General Health Questionnaire (GHQ), and Strengths and Difficulties Questionnaires (SDQ). Participants were assessed at baseline, at 3, and 6 months follow-ups. ANOVA with repeated measures and Friedman test were used to evaluate the effect of the interventions. Results: A total of 68 children and their parents enrolled in this study, of whom 53% were males. Post-intervention follow-ups revealed significant changes in mothers' general health questionnaire (p<0.001), and children's conduct problem (p<0.05), hyperactivity (p<0.001), and peer problems (p<0.05). Physical and emotional abuses significantly decreased (p<0.001). Conclusion: Our findings revealed that psychosocial interventions effectively improved child-parents interaction and mental health of parents. The effectiveness of interventions based on subgroup analysis and implications of the results have been discussed for further development of psychosocial interventions in the health system.

- Abstract
Background: This study aimed to determine the moderating effect of personality traits on the relationship between living with an addicted man and codependency., Methods: We selected 140 women (70 wives of addicted men and 70 wives of non-addicted men) through convenience sampling method and asked them to complete Spann-Fischer Codependency Scale and NEO-Five Factor Inventory., Findings: Codependency score was significantly higher among addicted men's wives. In addition, for these women, there was a strong positive correlation between codependency and neuroticism as well. Multiple regression analysis confirmed the significant interaction effects of being an addict's wife and personality traits of neuroticism, openness and agreeableness on codependency., Conclusion: Not all addicts' wives experienced codependency; women with a high level of neuroticism and low level of openness and agreeableness were more vulnerable to the stress of living with an addict and to codependency.

- Abstract
The geometry, frequency and intensity of the vibrational bands of aluminum(III) Tris-acetylacetone Al(AA)3 and its 1,3,5-(13)C derivative were obtained by the Hartree-Fock (HF) and Density Functional Theory (DFT) with the B3LYP, B1LYP, and G96LYP functionals and using the 6-31G* basis set. The calculated frequencies are compared with the solid IR and Raman spectra. All of the measured IR and Raman bands were interpreted in terms of the calculated vibrational modes. Most computed bands are predicted to be at higher wavenumbers than the experimental bands. The calculated bond lengths and bond angles are in good agreement with the experimental results. Analysis of the vibrational spectra indicates a strong coupling between the chelated ring modes. Four bands in the 500-390 cm(-1) frequency range are assigned to the vibrations of metal-ligand bonds.
