    Abstract Abstract Objective The high rate of treatment failure is a common problem in the treatment of methamphetamine use. Therefore, the aim of this research is to identify the most common causes of relapse in methamphetamine users. Method This is a qualitative study and of content analysis type. Information was collected using purposeful sampling and through semi-structured interviews and focus group discussions. The statistical population consisted of all people with the methamphetamine-use disorder in 2022 who were in the abstinence phase and participated in the meetings of the Narcotics Anonymous (NA) Center of Bojnord. Theoretical sampling continued until data saturation. A total of 10 one-on-one interviews were conducted, each lasting between 45 to 80 min. Additionally, two focus group interviews were conducted with six members in each group, lasting between 95 to 110 min and data saturation was achieved through these interviews. Data analysis was done using the content analysis method (Sterling). Recoding and Holsti's method were used to measure reliability; validity was then calculated through content validity assessment. Findings The results of the thematic analysis showed that laps and relapse factors were identified and categorized into 5 organizing themes, including negative emotional states, positive emotional states, negative physical states, interpersonal factors, and environmental factors, consisting of 39 basic themes. Result Identifying the risk factors leading to laps and relapse in methamphetamine users and increasing the knowledge in this field can lay the groundwork for preventive therapeutic interventions in this community.

    Abstract Background and aims: Over the last six months, the use of technology and the internet in Iran is significantly increased due to the coronavirus pandemic. This study aimed to investigate the effect of online career counseling on students’ psychological capital (i.e., self-efficacy, resilience, optimism, and hope) during corona isolation. Methods: The research design was quasi-experimental. The statistical population of this study included all students who were members of social media (i.e., WhatsApp, Telegram, Facebook, and LinkedIn). After the announcement and completion coronavirus anxiety questionnaire, 30 students who had obtained scores higher than the average level were selected and randomly assigned into experimental (15 students) and control (15 students) groups. Results: The findings showed that after the online counseling course, the intervention group outperformed the control group in psychological capital components (i.e., self-efficacy, resilience, optimism, and hope). Conclusion: According to the findings of this study, online counseling can be an effective source for career counselors, especially in developing countries. Besides face-to-face counseling, its services can help students increase their psychological capital.

    Abstract Objectives: This in vitro study is aimed at assessing whether implant primary stability is influenced by implant length in artificial bone with varying densities.
    Materials and methods: A total of 120 truncated-conical implants (60 long-length: 3p L, 3.8 × 14 mm; 60 short-length: 3p S, 3.8 × 8 mm) were inserted into 20, 30, and 40 pounds per cubic foot (PCF) density polyurethane blocks. The insertion torque (IT), removal torque (RT), and resonance frequency analysis (RFA) values were recorded for each experimental condition.
    Results: In 30 and 40 PCF blocks, 3p S implants exhibited significantly higher IT values (90 and 80 Ncm, respectively) than 3p L (85 and 50 Ncm, respectively). Similarly, RT was significantly higher for 3p S implants in 30 and 40 PCF blocks (57 and 90 Ncm, respectively). However, there were no significant differences in RFA values, except for the 20 PCF block, where 3pS implants showed significantly lower values (63 ISQ) than 3p L implants (67 ISQ) in both the distal and mesial directions.
    Conclusions: These results demonstrated that the implant's length mainly influences the IT and RT values in the polyurethane blocks that mimic the mandibular region of the bone, resulting in higher values for the 3p S implants, while the RFA values remained unaffected. However, in the lowest density block simulating the maxillary bone, 3p L implants exhibited significantly higher ISQ values.
    Clinical relevance: Therefore, our data offer valuable insights into the biomechanical behavior of these implants, which could be clinically beneficial for enhancing surgical planning.

    Abstract In recent years, the intrinsic magnetic properties of magnetic nanoparticles (MNPs) have made them one of the most promising candidates for magnetic resonance imaging (MRI). This study aims to evaluate the effect of different coating agents (with and without targeting agents) on the magnetic property of MNPs. In detail, iron oxide nanoparticles (IONPs) were prepared by the polyol method. The nanoparticles were then divided into two groups, one of which was coated with silica (SiO 2 ) and hyperbranched polyglycerol (HPG) (SPION@SiO 2 @HPG); the other was covered by HPG alone (SPION@HPG). In the following section, folic acid (FA), as a targeting agent, was attached on the surface of nanoparticles. Physicochemical properties of nanostructures were characterized using Fourier transform infrared spectroscopy (FT-IR), transmission electron microscopy (TEM), and a vibrating sample magnetometer (VSM). TEM results showed that SPION@HPG was monodispersed with the average size of about 20 nm, while SPION@SiO 2 @HPG had a size of about 25 nm. Moreover, HPG coated nanoparticles had much lower magnetic saturation than the silica coated ones. The MR signal intensity of the nanostructures showed a relation between increasing the nanoparticle concentrations inside the MCF-7 cells and decreasing the signal related to the T 2 relaxation time. The comparison of coating showed that SPION@SiO 2 @HPG (with/without a targeting agent) had significantly higher value in comparison to Fe 3 O 4 @HPG. Based on the results of this study, the Fe 3 O 4 @SiO 2 @HPG-FA nanoparticles have shown the best magnetic properties, and can be considered promising contrast agents for magnetic resonance imaging applications.

    Abstract Injectable materials have shown great potential in tissue engineering applications. However, bacterial infection is one of the main challenges in using these materials in the field of regenerative medicine. In this study, biogenically synthesized silver nanoparticle-decorated multi-walled carbon nanotubes (Ag/MWCNTs) were deployed for adorning biogenic-derived AgNPs which were subsequently used in the preparation of thermosensitive hydrogels based on hyaluronic acid encompassing these green-synthesized NPs. The antibacterial capacity of AgNPs decorated on MWCNTs synthesized through Camellia sinensis extract in an organic solvent-free medium displayed a superior activity by inhibiting the growth of Gram-negative (E. coli and Klebsiella) and Gram-positive (S. aureus and E. faecalis). The injectable hydrogel nanocomposites demonstrated good mechanical properties, as well. The thermosensitive hyaluronic acid-based hydrogels also exhibited T

    Abstract Agricultural processing industries in rural areas could bring the benefits of efficiency of products, increased employment and reduced agricultural waste. However, the success of the packaging for processing industries in the developing rural economy depends on the choice of the best location for the establishment of related industries. The purpose of this study was to determine the optimal location of processing industries - depending on the direction of economic development in rural saffron packaging in the Torbat city. Information was collected in two ways from a library. The population of the study area was in the fields of Torbat city. 19 villages were selected as samples using Cochran formula, 356 households were defined as households in the sample. Then to locate the packaging processing industries for saffron use of index of localization of the human dimension was considered normal. The data collected for analysis was gathered by using questionnaires, and the AHP model and SPSS software package were used. In this regard, the results suggest that the correlation between processing industries - depending on the size of saffron and economic development in the rural fields is based on research. Thus, the best location for saffron processing industries in the region, the villages and Colonel Asad were identified considering the natural conditions and human factors (fertile soil, access roads, etc.).
