Abstract
As climate change intensifies the frequency and severity of droughts, adaptive behavior becomes increasingly crucial. Farmers' capacity to modify their practices in response to evolving climate conditions is vital for ensuring long-term agricultural sustainability and food security. Therefore, this study aims to investigate the psychological factors affecting farmers' adaptation behaviors in response to drought, using the health belief model. The sample comprised 380 farmers from Kohdashat County in Lorestan Province, western Iran, selected via a three-stage cluster sampling method. Data were collected using a researcher-designed questionnaire, whose validity and reliability were confirmed. Structural equation modeling (SEM) results indicated that self-efficacy; perceived benefits, perceived vulnerability, and perceived barriers explained about 49% of the variance in farmers’ adaptation behavior. Perceived benefits emerged as the strongest predictor of adaptation, while cues to action and perceived severity were insignificant. These findings support the health belief model's practicality and effectiveness in examining water conservation behavior among Iranian farmers.

Abstract
Aim: Breast cancer is the most common cancer among women worldwide. This comparative study was designed to investigate the knowledge, attitude, and practice of medical and non-medical female students concerning breast self-examination (BSE) in two different universities in Shiraz, Iran. It also examined the relationship between the students' knowledge, attitude, practice and type of academic education. Methods: A cross-sectional survey was conducted in Shiraz, Iran. 394 female students were selected using proportionate stratified random sampling (292 non-medical and 102 medical). A self-administered questionnaire was used for data collection, and the obtained data were analyzed descriptively. Findings: Medical students were more aware of BSE timing, stages of BSE performance and initiation age of BSE. Medical female students were also more likely to consider BSE as efficient, not difficult and time consuming, and to acknowledge that as a method for decreasing the probability of cancer. Regular BSE performance rate for both groups was very low and unsatisfactory (non-medical 2.1% and medical 2.9%). The results of t-test and Chi-square revealed significant differences across BSE knowledge, attitude and practice with type of academic education (medical or non-medical) (P=001). Conclusion: Based on the findings, the medical students were more knowledgeable and showed a better attitude and responded more positively than the non-medical student, but both groups showed low level of BSE practicing that is of a concern. The supportive role of universities in providing students with necessary information about breast cancer is suggested, and its prevention methods should be highlighted. Additionally, there is a need to a supportive environment which facilitates students’ access to qualified health care services.

Abstract
This study aimed to provide a model for improving the quality of women's and girls' leisure time in the family with an approach based on physical activity in Isfahan province. This research was carried out using a qualitative method with a systematic approach of grounded theory. The theoretical population consisted of knowledgeable and experienced women's sports and leisure professors who also used the snowball method for sampling. The data collection tool and method were semi-structured individual interviews, and the interviews continued until the theoretical saturation of 15 interviews. For data analysis, a systematic approach includes three main steps: open coding, axial coding and selective coding. In the axial coding stage, the connection between the following categories of causal conditions (support of important others, organizing, applicability of activities, institutionalization of activities); context factors (environmental attractions, environmental conditions, sports attractions(; interfering factors (evolutionary changes, cultural and social barriers, gender hegemony, macro trends, structural barriers); strategies (education and culture building, measures to support women's recreational sports, promotion and development of physical activities, respect for the dignity of women and girls, justice in the implementation of activities, media support) and consequences of qualifying women's leisure time (reducing behavioral disorders, individual empowerment, collective empowerment, increasing participation) in terms of coding paradigm in Sports manufacturing corporations was determined; also in selective coding phases, each component of coding paradigm described. The province's sports managers can use the signs, concepts and categories identified in their plans to improve the leisure time of women and girls in the family with an approach based on physical activity and use the proposed appropriate strategies to compensate for the backwardness and development of women's sports.

Abstract
Aims: How to design spaces in cities can have different effects on citizens. The objectives of this study can be to examine the impact of biophilic urban space on the stress of people.
Methods: The research method is quasi-experimental. The statistical population of the study consists of 20 bachelor and master students in the field of architecture and urban planning at Tabriz University of Islamic Arts in the academic year 1400. First, students' health was identified using a call announcement and a demographic questionnaire, and these individuals were quantified for stress with the help of a smart wristband while viewing images of biophilic and non-biophilic urban spaces with the help of virtual reality glasses.
Findings: Analysis of the results shows that the average change in stress of individuals while viewing non-biophilic images was approximately 5/2 units higher than biophilic ones in the second minute. p-Value is significant between individuals with education in biophilic state and rest in 1 minute and non-biophilic in 2 minutes. The difference between stress number in non-biophilic state and biophilic in 2 minutes is significant (p-value = 023/0) and shows the positive effect of biophilic approach on reducing stress that this efficiency can be considered in the design of future urban spaces.
Conclusion: Special attention of urban designers on the structure of spaces and the use of extraction measures from the biophilic model in different scales cause the design or organization of spaces that significantly reduce the stress of people living in cities

Abstract
Introduction
Media literacy leads to public rights discourse. The discourse of public law is effective in monitoring the government through the qualitative and quantitative expansion of the demanding element. People are more persistent in insisting on the rights they are sure they have the right to have. In all societies, the interested people with the power of influence in the field of media turn society into an unequal campaign. The way to deal with this is to expand the right to media literacy. In addition, in advertisements that aim to show reality and distort it deliberately and biasedly, if the audience does not have enough knowledge and is deprived of many sources to benefit from information, it will not result in a distortion of reality or an inorganic change of public opinion. The action of the government in promoting media literacy, in addition to fulfilling one of the human rights, is a smart action that is effective in the field of public participation. If citizens benefit from the right to media literacy, we are faced with a controlling power that relies on collective wisdom. The present article is trying to find a universal solution through theory in order to have a micro-oriented government by relying on the processing citizens.
Methodology
The method of carrying out library research is analytical-descriptive. In this regard, in order to answer the questions and test the assumptions, the method of content analysis has been used.
The information has been collected by the library method and by extracting vouchers from reliable sources. After collecting information and laws in the fields of freedom of expression, freedom of information, media rights, public opinion and the right to education, the issue has been analyzed. In order to benefit from the role of interactive media, attention has been paid to the recent laws of the parliament and the amount of use of keywords related to those laws in the virtual space before they were approved in the public forum of the parliament. The findings indicate the approval of some recent laws based on public opinion, especially regarding the country's annual budget. The statistical population considered for the research is the Islamic Republic of Iran. Although, the ideas of researchers from other countries and other legal systems have also been used,

Media literacy guarantees the exchange of correct information and rational media filtering by using public wisdom. Media literacy significantly reduces the level of political indifference, a crisis facing modern society. The level of sudden arousal of motions by the media is less observed in societies that have a favorable level of media literacy. In addition to monitoring the government's power, increasing media literacy will increase the psychological security of society. The prerequisites for mastering the skill of selection are awareness and freedom. Strengthening and understanding the world
of life by guaranteeing fundamental rights lead to the evolutionary evaluation of justice by citizens. The supervisory function of interactive media plays a critical role in increasing responsibility and accountability in various social fields.
The regulatory role of the media is directly related to the recognition and guarantee of the public domain. The government is obliged to protect the public domain. The exchange of information in the public sphere is considered a part of the new freedoms and the continuation of the right to freedom of expression. People are trying to achieve mutual understanding in their interactions, and the active and interpretive presence of elites in the public domain plays a key role in promoting media literacy. In interactive media, where it is possible to benefit from collective wisdom through public opinion, and in social media, where content is produced by the public, it finds symmetry with Habermas' concept of the world of life. The active presence of citizens in the public domain requires guaranteeing freedom of expression and the right to access information. In this regard, changes in the laws related to the right to teach media literacy are inevitable.
Conclusions
In the modern government, with the development and growth of the media, the need for media literacy has become an inseparable part of the lives of the citizens of the modern government. The government is obliged to continuously review the laws and regulations in line with media innovations and create the evolutionary course of society through deregulation and policymaking based on needs. The power of cognition, the power of judgment, and data analysis are the fundamental foundations of media literacy education. Media literacy provides the power of understanding, the power of judgment, and the possibility of participating in collective discussions. In modern government, media literacy is the most important platform for the formation of the public sphere. By improving media literacy, the level of conscious participation improves. The public pays more attention to public domain issues.
Operational solution: knowing the laws related to the theoretical field and making demands is based on the principle of the rule of law.

Abstract
The issue of job absenteeism as a critical factor for organizations brings significant financial losses. The absence is one of the all-consuming challenging and time consuming problems organizations could face and in economic point of view, one of the factors increasing the cost of production. These issues are more common in estate owned organizations. Given the need to identify causes of absenteeism and staff desertion, this study, with scientific and realistic analysis on the causes of absenteeism, try to find solutions and ways to overcome these issues. Reviewing experiences of some management scientists and sociologists, Q-methodology used to identify important factors causing employees absenteeism which those factors were finalizing using factor analysis. Statistical population was staff of the case study where three of the specialists interviewed, 40 Q identified and prioritized by the participants. 5 factors were identified, which collectively illustrate the importance of performance-based pay, developing systematic indicators to evaluate performance, enriching jobs by redefining the identity, awareness and transparency in the formulation and implementation of organizational structure.

Abstract
The toxicity of garlic is confirmed on some agricultural pests. The aim of this study was to comparatively evaluate the sensitivity of Podisus maculiventris (Say) to garlic extract and two insect pests: Mediterranean flour moth Ephestia kuehniella (Zeller) and Colorado potato beetle Leptinotarsa decemlineata (Say). LC50 was calculated at 8.02% for E. kuehniella. The results showed toxic compounds in garlic extract delayed all developmental stages and reproduction parameters of L. decemlineata. In contrast, there were no considerable negative effects on many of the biological parameters of the predatory insect, P. maculiventris. The results suggest that garlic, as a green pesticide, could be considered an environmentally suitable alternative in pest management programs.

Aims: In this study, the replacement effect of dietary fish meal with AquPro (Processed soybean meal) was assessed on growth performance, body composition and total protease activity of rainbow trout (Oncorhynchus mykiss) over a period of 6 weeks.
Materials and Methods: In this experimental study, at the beginning of the trial, 5 experimental diets were formulated with fish meal as control (A) and diets with 25% (B), 50% (C), 75% (D) and 100% (E) AquPro, respectively. At the end of the feeding trial, growth performance, body composition and total protease activity from pyloric caeca and intestine were measured.
Findings: The results indicated that the WG, SGR and ADG in experimental diet C were the highest and showed a significant difference with other treatments (p<0.05). However, the status index in experimental diet C was lower than other treatments, but did not show significant differences (p>0.05). The moisture content, fat, and body ash were respectively, significantly higher in experimental diets A, B and E than those of other treatments (p<0.05), But the highest amount of protein was observed in the experimental diet of C, which did not show any significant difference with other treatments (p>0.05). The highest total protease activity from pyloric caeca and the intestine was observed in the fish fed with diet C which showed a significant difference with other diets (p<0.05).
Conclusion: Based on the results of growth performance, body composition, and total protease activity was revealed that the diet containing 50% AquPro could be appropriate for rainbow trout growth.

Abstract
Objective: Because of the necessity of more effective treatments for the nervous system injuries and considering the role of survivin in cellular proliferation and apoptotic cell death, we have monitored survivin gene expression changes during the course of regeneration in injured sciatic nerves and also L4-L6 segments of spinal cord. Materials and Methods: We used adult male NMRI mice as a model. After anesthetizing the animals, the right sciatic nerve was transected and at the indicated times (3, 6, 12, 24, 48, 96 and 144 hours) the animals were sacrificed and both distal and proximal segments of the transected sciatic nerve, intact left sciatic nerve and L4-L6 segments of spinal cord were dissected. The total RNA was extracted from each sample and semi-quantitative RT-PCR with specific primers for survivin and also 2-microglobulin genes, as an internal control, was performed. To determine cellular distribution of survivin protein, 6 days (144 hours) after the axotomy, survivin protein expression was evaluated using immunohistochemistry technique. Results: Our results demonstrated the expression of both survivin140 and survivin40 in distal and proximal segments of sciatic nerve with different intensity, where the expression of survivin140 was higher than survivin40. In spinal cord segments, only survivin140 expression was detected. In Immunohistochemistry analysis of spinal cord segments, both the nuclear and cytoplasmic distribution of survivin protein was observed. In contrast, survivin protein has not been detected in either distal or proximal segments of sciatic nerve. Conclusion: Our data suggest that survivin is differentially expressed and spliced during the course of regeneration in damaged nerve and spinal cord. It seems that manipulation of expression and/or splicing of survivin could potentially affect the process of regeneration in nerve and/or spinal cord injuries.

Abstract
α-crystallin is a member of small heat shock protein family (sHSP) which shows both structural and chaperone functions. This protein plays important role in eye lens transparency and indicates protective function in the other tissues. The lenticular levels of copper ions significantly enhance in diabetic patients, aged and cataractous lenses. In eye lenses, the free copper ions induce ascorbic acid auto-oxidation, leading to formation of dehydroascorbic acid and other oxidative products as well as reactive oxygen species. The oxidized forms of ascorbic acid along with the reducing sugars enter into pathological reactions with the eye lens proteins, forming toxic advanced glycation end-products (AGEs). As one of the main components of eye lens antioxidant defense mechanism, glutathione could scavenge the copper ions, inhibiting the formation of reactive oxygen species in eye lenses.
In the current study, the structural and functional properties of human αB-crystallin were assessed using different spectroscopic methods. In the presence of copper ions, αB-crystallin exhibited important alterations in both structure and chaperone activity which upturned in the presence of glutathione. Moreover, incubation of human αB-crystallin with copper resulted in significant increase in the protein oligomeric size distribution which largely prevented upon simultaneous incubation with glutathione.
Overall, glutathione may scavenge free copper ions in the lenticular tissue, inhibiting their damaging effects on crystallin proteins and other redox-sensitive molecular targets such as ascorbic acid. Our results may introduce a new protective role for glutathione which is highly important in diabetic and aged lenses showing increased levels of copper ions.

Abstract
Objective: Evaluation of the effects of Toxoplasma gondii infection on spermatogenesis in male rats. Materials and Methods: The RH strain of T. gondii tachyzoites were injected interaperitoneally in an infected group of 35 rats, while 21 rats were used as controls. Each ten days from 10- 70 days of post-infection (PI), 5 rats from infected group and 3 rats from control group were scarified. The percentage of body weight to testis weight ratio (BTR) as well as sperm parameters and fructose levels in seminal vesicles and coagulating glands (SVCG) were investigated. An IgG ELISA kit was designed for serologic diagnosis of infection in the rats. Results: All rats injected with T. gondii tachyzoites were infected from 10-70 PI. Sperm motility from 10-70 PI, sperm viability from 10-60 PI and sperm concentration from 20-60 PI were significantly decreased in the infected group (P<0.05); sperm abnormality was significantly increased in the infected group on days 30, 40 and 50 PI (P < 0.05). BTR in the infected group was not significantly changed compared to control group (P>0.05). Fructose level in SVCG in the infected group was significantly decreased on days 10-50 PI (P < 0.05) compared to control. Conclusion: According to the results, toxoplasmosis can cause impermanent impairment on the spermatogenesis in the male rats.

Abstract
Objective: The goals of the study are evaluation the effect(s) of food deprivation as a social stress on testis structure. We also investigated the effects of melatonin treatment as an antioxidant component and inequality on the effect(s) of food deprivation. Methods: We investigated the improving effects of melatonin and social stress (food deprivation) on 42 male rats in 7 groups including control, sham, melatonin received (M), food deprivation (1/3 of control daily food) plus observation (FD), FD + melatonin (FDM), isolated FD (FDi), and FDi + melatonin (FDMi) groups. After 14 days, rats' testes were studied using immuno histochemistry and TUNEL assays to determine the number of apoptotic cells. Biochemical evaluation was taken on malodialdehide (MDA) and glutathione (GSH). ANOVA and Tukey's tests were done to analyse the data. PResults: The results of sham group was declined for similarity to results of control group. In FD group, MDA was increased significantly (PConclusion: Food deprivation can induce oxidative stress which is associated with increasment of apoptotic cells in testis. Isolation can compensate these effects. These results refer to inequality. Since melatonin is recognized for its anti-oxidative and improving effects, we have shown involvement of oxidative stress mechanisms on the stress of food deprivation with inequality.

Abstract
Objective: This study presents a simple method for isolation, expansion and purification of neonatal mouse spermatogonial stem cells. Methods: We used enzymatic digestion to isolate a cell suspension of spermatogonia and Sertoli cells from neonatal 2-day-old mice. The cells were cultured in DMEM/F12 that contained 10% serum for two weeks. Sertoli and spermatogonia cell characteristics were confirmed by examining for the presence of vimentin and PLZF proteins, respectively. To assess the rate of spermatogonia stem cell expansion, the area and number of colonies were measured during the two weeks of culture. At the end of the second week, we detected spermatogonia cell-specific expressions of the Stra8, Piwill2, DAZL, and Mvh genes. Results: Current results indicated that isolated Sertoli and spermatogonia cells were immunopositive for specific markers. During the culture period, a significant difference was seen in the number and area of spermatogonial stem cell colonies (PConclusion: Our study showed that co-culture of spermatogonia and Sertoli cells from same source provides a convenient and efficient environment. This co-culture, without the addition of external growth factors and chemical manipulations, can be used for proliferation of spermatogonia stem cells.

Abstract
Objective: Antioxidants are essential for sperm motility. Calligonum extract possesses the important antioxidants catechin and quercetin. This study investigates the effects of calligonum extract on sperm parameters and the rate of apoptosis in testes of aging male mice. Methods: We initially performed a dose response test with using three doses of calligonum (10 mg/kg, 30 mg/kg and 50 mg/kg). A total of 25 aging male mice (11-13 months) were divided into the following groups of five mice each: control, sham and three experimental groups. The experimental groups received IP injections of calligonum extract (10 mg/kg, 30 mg/kg, 50 mg/kg) weekly for up to five weeks. The sham group received IP injections of DMSO. At the end of the injection period, mice were sacrificed and sperm parameters analyzed. To determine apoptosis in testes, we performed TUNEL staining. Results: Our results showed that after calligonum treatment, there were improved sperm parameters in the 30 mg/kg-treated group compared to the other groups (P≤0.05). Conclusion: Calligonum extract (30 mg/kg) can improve sperm parameters and decrease apoptosis in the testes of aging male mice. This herbal extract can be employed as an antioxidant component for clinical usage.

Abstract
Objective: Diabetic neuropathy leads to axonal transport abnormalities. However its mechanism and the beneficial effects of exercise on these abnormalities are not well documented. The present study aims to investigate KIF1B mRNA in spinal cord sensory neuron tissue of Wistar male rats with diabetic neuropathy following endurance training. Methods: We randomly assigned 12 male Wistar rats into three groups: diabetic trained, diabetic untrained and healthy control. Intraperitoneal injection of a STZ (streptozotocin) solution (45 mg/kg) was used to induce diabetes. At two weeks after STZ injections, the mechanical allodynia and thermal hyperalgesia tests demonstrated the presence of diabetic neuropathy. A moderate endurance training protocol was performed for a six-week period. At 24 hours after the final training session, the rats were sacrified and the L4-L6 sensory neurons of the spinal cord tissue were removed. KIF1B mRNA expression was performed using real time-PCR. Results: Diabetic neuropathy led to increased KIF1B gene expression in the diabetic untrained group compared with the intact control group (p=0.03). Compared with the diabetic untrained group, training significantly decreased KIF1B gene expression (P<0.05) and blood glucose levels (P=0.0001) in the diabetic trained group. Conclusion: KIF1B mRNA up-regulation in sensory neurons of STZ-diabetic rats is a factor which can be involved in abnormal axonal transport. Endurance training as a non-pharmacotherapy strategy can modulate and return KIF1B to approximate normal levels.

Abstract
Objective: This study presents an efficient, cost-effective method to improve proliferation and colonization of spermatogonial stem cells (SSCs) in vitro. Methods: Isolated SSCs from neonate mice were cultured in DMEM culture medium with 10% fetal bovine serum (FBS). In the first phase of the study, the temperature was controlled by low intensity pulsed ultrasound stimulation (LIPUS) of the plate that contained the culture medium. In the next phase, SSCs were stimulated by LIPUS with 200 mW/cm2 with 20% and 40% duty cycle for five days. Proliferation and colonization of SSCs were on the seventh day. Results: LIPUS treatment of mouse SSCs increased the proliferation rate and colonization of SSCs in the experimental groups compared to the control group. Average proliferation rate in the 20% duty cycle group was 1.46±0.06, in the 40% duty cycle group it was 2.00±0.1 and for the control group, it was 1.26±0.06. The average number of colonies in the 20% duty cycle group was 24±7.7, whereas the 40% duty cycle group had 62±1.4 colonies and the control group had an average of 19±5.5 colonies. Average colony diameters were as follows: 186.6±2.07 µm (20% duty cycle group), 185.3±4.4 µm (40% duty cycle group) and 190.0±2.0 µm (control group). Our results showed a significant increase in proliferation rate and number of colonies in the experimental groups compared to the control group (P<0.05), whereas no significant differences were observed between groups in colony diameters. Conclusion: These results suggested that LIPUS treatment can be an efficient, cost-effective method to improve proliferation and colonization of SSCs during in vitro culture.
