Abstract
INTRODUCTION Tinnitus is the most common symptom of auditory system disorders. It affects the quality of life of millions of people, but it is still incurable in most cases. Vagus nerve stimulation (VNS) therapy is a potential new treatment for subjective tinnitus. In this study, transcutaneous vagus nerve stimulation (tVNS) combined with tones was utilized to treat salicylate-induced tinnitus since salicylate is a reliable and convenient approach for rapidly inducing tinnitus. METHODS Wistar rats were divided into acoustic stimulation alone (AS, n = 6), tVNS alone (n = 6), and tVNS with AS (n = 6) groups for behavioral and electrophysiological tests. They were assessed by auditory brainstem response (ABR), prepulse inhibition (PPI), gap prepulse inhibition of the acoustic startle (GPIAS), social interactions, and aggressive behavior tests at baseline and seven days' post-salicylate (175 mg/kg, twice a day) injection. RESULTS The inhibition percentage of the GPIAS test was significantly reduced post-salicylate injection in the tVNS and AS alone groups, while it was not significant in the tVNS with AS group. There was no significant difference in the mean percentage of the GPIAS test between the tVNS groups (with or without AS) after salicylate injections. Social interactions were significantly different in the AS alone group pre- and post-salicylate injections, but they were not significant in other groups. Moreover, the results of aggressive behavior tests showed significantly increased post-salicylate injections in the AS alone group, while they were not significant in the tVNS groups (with or without AS). CONCLUSIONS The current study revealed that the application of tVNS alone produced improved social interaction and mood and alleviated salicylate-induced tinnitus severity. Moreover, combining tVNS with acoustic stimulation can prevent salicylate-induced tinnitus.

Abstract
Solar heat management & green air-conditioning are among the major technologies that could mitigate heat islands phenomenon while minimizing significantly the CO2 global foot-print within the building & automotive sectors. Chromogenic materials in general, and thermochromic smart coatings especially are promising candidates that consent a noteworthy dynamic solar radiation Infrared (NIR-IR) regulation and hence an efficient solar heat management especially with the expected increase of the global seasonal temperature. Within this contribution, two major challenging bottlenecks in vanadium oxide based smart coatings were addressed. It is validated for the first time that the NIR-IR modulation of the optical transmission (∆TTRANS = T(T〈TMIT) - T(T〉TMIT) of Vanadium oxide based smart coatings can be controlled & tuned. This upmost challenging bottle-neck controllability/tunability is confirmed via a genuine approach alongside to a simultaneous drastic reduction of the phase transition temperature TMIT from 68.8 °C to nearly room temperature. More precisely, a substantial thermochromism in multilayered V2O5/V/V2O5 stacks equivalent to that of standard pure VO2 thin films but with a far lower transition temperature, is reported. Such a multilayered V2O5/V/V2O5 thermochromic system exhibited a net control & tunability of the optical transmission modulation in the NIR-IR (∆TTRANS) via the nano-scaled thickness' control of the intermediate Vanadium layer. In addition, the control of ∆TTRANS is accompanied by a tremendous diminution of the thermochromic transition temperature from the elevated bulk value of 68.8 °C to the range of 27.5-37.5 ºC. The observed remarkable and reversible thermochromism in such multilayered nano-scaled system of V2O5/V/V2O5 is likely to be ascribed to a noteworthy interfacial diffusion, and an indirect doping by alkaline ions diffusing from the borosilicate substrate. It is hoped that the current findings would contribute in advancing thermochromic smart window technology and their applications for solar heat management in glass windows in general, skyscraper especially & in the automotive industry. If so, this would open a path to a sustainable green air-conditioning with zero-energy input.

Abstract
During aging, general cellular processes, including autophagic clearance and immunological responses become compromised; therefore, identifying compounds that target these cellular processes is an important approach to improve our health span. The innate immune cGAS-STING pathway has emerged as an important signaling system in the organismal defense against viral and bacterial infections, inflammatory responses to cellular damage, regulation of autophagy, and tumor immunosurveillance. These key functions of the cGAS-STING pathway make it an attractive target for pharmacological intervention in disease treatments and in controlling inflammation and immunity. Here, we show that urolithin A (UA), an ellagic acid metabolite, exerts a profound effect on the expression of STING and enhances cGAS-STING activation and cytosolic DNA clearance in human cell lines. Animal laboratory models and limited human trials have reported no obvious adverse effects of UA administration. Thus, the use of UA alone or in combination with other pharmacological compounds may present a potential therapeutic approach in the treatment of human diseases that involves aberrant activation of the cGAS-STING pathway or accumulation of cytosolic DNA and this warrants further investigation in relevant transgenic animal models.

Abstract
Aripiprazole is an efficacious treatment for both the positive and negative symptoms of schizophrenia and is also commonly used as a mood stabilizer. It is associated with better tolerability compared with other antipsychotics. However, there are reports of patients who experience problem gambling, hypersexuality, obsessive-compulsive symptoms, and other impulsive and/or compulsive behaviors as a result of aripiprazole administration and/or dosage increase. We aimed to do a systematic review of case reports published in this regard. After screening more than 6000 titles and abstracts in ten scientific search engines, we found 35 related records comprising 59 cases. The majority of cases (n = 42, 71.18%) were male, the mean age was 33.83 years (± 13.40), and the average daily dose of aripiprazole was 11.63 mg (± 6.94). The results of our review showed that the most frequently published impulsivity adverse effect of aripiprazole is gambling, followed by hypersexuality, obsessive-compulsive symptoms/disorder, problem eating, trichotillomania, problem shopping, and kleptomania. These symptoms were experienced both by patients who had previous problems in these areas and those who did not. In the majority of cases, the symptoms appeared within 30 days after aripiprazole administration started and ceased within 30 days of its discontinuation and/or dose decrease. Clinicians should be aware of impulsivity adverse effects, monitor them, and educate both patients and the family about them.

Abstract
NSSI has recently been recognized as a significant health issue given its documented association with psychopathology and across a broad spectrum of psychiatric disorders. It has been found that individuals experiencing heightened emotions, which is referred to as an emotional cascade, are more likely to engage in self-injury behaviour due to low levels of distress tolerance (DT). The current meta-analysis using PRISMA guidelines sought to quantify the strength of the association between DT and lifetime frequency of NSSI using 22 eligible studies (N = 14,588; F = 60.7%; age = 23.35 ± 7.30), mainly from the United States. The correlation between emotional DT and NSSI was a small negative correlation (r = -.14), and it was non-significant for behavioural DT and NSSI (r = .02). Also, the effect-size was significant for studies that used interview-based measure of NSSI (r = -.24), and it was non-significant when self-report measures of NSSI (r = -.11) utilized. The association between DT and NSSI was significant and negative across the general population (r = -.47), university students (r = -.17), and inpatients (r = -.27); surprisingly, it was significant and positive among adolescents or high school students (r = .17). The observed effect-sizes were independent of publication year, mean age and its standard deviation, study quality, female proportion, DT, NSSI measures reliability, and clinical status. Future studies on NSSI should consider DT as a spectrum from distress intolerance to distress over-tolerance, given that it seems it has different functions when different samples (e.g., adolescents) are studied.

Abstract
The present study aimed to investigate the psychometric properties and measurement invariance of the Compulsive Online Shopping Scale (COSS) in an Iranian population. The total sample of 802 participants (257 females; Mean age = 22.27, SD = 2.83) were selected via convenience sampling from Tehran, Iran. Confirmatory Factor Analysis supported the 7-factor structure of the COSS as proposed in the original study. The measurement invariance found in this study suggests that the COSS provides sufficiently unbiased use among males and females. The current findings also support the concurrent validity of the Persian COSS, which exhibited positive and significant associations with loneliness, impulsivity, obsession, internalized symptoms, and Internet use. Furthermore, results confirm the convergent validity of the Persian COSS and showcased acceptable internal consistency for all factors, and the total score. The findings of the present study indicate that compulsive online shopping could be assessed adequately in Iranian samples using the COSS.

Abstract
Background: Studies have shown that tinnitus patients have difficulties in cognitive function such as memory and attention. The Stroop task engages the attention network where one aspect of the stimulus is noticed while the other one is ignored. Thus, Stroop training can improve the patient's cognitive control and ability to ignore the tinnitus signal. Method: Thirty chronic tinnitus (> 6 months) patients were included in this study. They were distributed into two 15-member groups: intervention and control. Common audiometric, psychometric, and psychoacoustic evaluations of tinnitus were performed for two groups before intervention and after auditory Stroop training of group 1. Results: There was significant difference in the quality of life and THI scores, VAS of annoyance, and reaction time of Stroop task before and after intervention in group1. The decreased reaction time was positively correlated with improved quality of life, THI score, and VAS of annoyance. Conclusion: Cognitive rehabilitation using tasks such as auditory Stroop can be effective in controlling tinnitus by improving cognitive control.

Abstract
Problematic Social Media Use (PSMU) has been defined as the lack of regulation of one's use of social media associated with negative outcomes in everyday functioning. Previous meta-analyses reported PSMU prevalence before the beginning of the COVID-19 pandemic and based the estimates on the cut-off scores, which are debatable in the current fields. The present meta-analysis aims to explore whether PSMU, as assessed by the most used self-report scale (i.e., the Bergen Social Media Addiction Scale; BSMAS), increased across the world (i) since the first published study on this topic (i.e., in the last seven years), (ii) since the beginning of the COVID-19 pandemic, and (iii) depending on age, gender and the income level of the countries. The meta-analysis involved 139 independent samples with 133,955 respondents from 32 countries spanning seven world regions. The results show that PSMU: (i) is significantly higher in low-income countries (LIC); (ii) did not increase in the last 7 years overall and after the beginning of the COVID-19 pandemic, except for LIC; (iii) did not vary depending on age and gender. The higher prevalence of PSMU reported during the COVID-19 pandemic by some single studies may have been a transient phenomenon to cope with physical distances in some countries, whilst, in others, an overall increase of PSMU occurred. High levels of PSMU in LIC might be explained based on socio-cultural differences between countries, but also with the higher prevalence of mental disorders in LIC since PSMU might be a symptom of other, more primary psychiatric disorders.

Abstract
AIMS Previous studies have shown that Cervical myofascial pain syndrome with dizziness (CMPS-D ) is one of the most common causes of cervicogenic dizziness and is associated with challenge in diagnosis and treatment. this study aimed to investigate the Romberg neck torsion test in patients with CMPS-D and healthy controls. MATERIALS AND METHODS Cross-sectional, observational study. twenty patients with CMPS-D were compared with twenty healthy controls. the Romberg (neutral position and neck torsion) and smooth pursuit neck torsion tests were performed in patients with CMPS-D and healthy controls. RESULTS The results confirmed that there are significant differences in the Romberg neck torsion test between subjects with CMPS-D and healthy controls (p < 0.05). in addition, There was a significant correlation between Romberg neck torsion and smooth pursuit neck torsion results (p < 0.05). CONCLUSION The results of Romberg neck torsion test in CMPS-D subjects were different from those in healthy controls, which was attributed to neck pain and changes in cervical proprioception input. Romberg neck torsion is a new method for assessing cervicogenic dizziness.

Abstract
This study aimed to assess Problematic Social Media Use (PSMU) among Iranian adolescents and explore potential risk and protective factors. In the present cross-sectional study, 3375 Iranian adolescents were recruited online and completed questionnaires. Latent profile analysis (LPA) was performed to identify groups with various levels of PSMU. Indicator variables included standardized factor scores for PSMU, attention-deficit/hyperactivity disorder, sensation-seeking, internet addiction, loneliness, social anxiety, internalizing symptoms, social support and self-esteem. Five groups were identified relating to severities of PSMU and other factors: low-risk: n = 823 (24.4 %); low-to-moderate-risk: n = 835 (24.7 %); moderate-risk: n = 630 (18.7 %); moderate-to-high-risk: n = 584 (17.3 %); high-risk: n = 503 (14.9 %). Multiple factors, including sensation-seeking, internalizing symptoms, social anxiety, loneliness, internet addiction, attention-deficit/hyperactivity disorder, low self-esteem and low perceived social support, statistically predicted PSMU. The current findings may help identify Iranian adolescents who are particularly vulnerable to PSMU and assist in intervention development.

Abstract
Impairments of auditory processing are among frequent findings in dyslexia. However, it is unclear how auditory signals are gated from brainstem to higher central processing stages in these individuals. The present study was done to investigate auditory sensory gating in children with developmental dyslexia (DD), and to determine whether sensory gating correlates with performance on behavioural tasks. Auditory sensory gating at P50, N1 and P2 waves was evaluated in two groups including 20 children with DD and 19 children with typical reading development (TRD). Behavioural tests were used to evaluate phonological working memory (PWM) and selective attention abilities. Sensory gating in children with DD was significantly less efficient than their peers at P50, N1 and P2 waves. Lower auditory evoked potential (AEP) amplitudes were found in the DD group. The children with TRD scored better in all the behavioural tests. Relationships were reported between sensory gating at P50, N1, P2 and behavioural performance in the two groups. Children with dyslexia had deficient sensory gating in comparison with controls. In addition, children with dyslexia experienced problems with PWM and selective attention tasks. The function of sensory gating was associated with attentional and PWM performances in this group.

Abstract
Objectives Premature birth causes some permanent or temporary abnormalities in the hearing system of the newborn. Inadequate development of the central auditory nervous system and balance, as well as the delay in the formation of the nerve myelin, can be the cause of many hearing disorders, including permanent or temporary auditory neuropathy spectrum disorder (ANSD). The present study aims to identify and understand developmental delay disorder in the hearing system of infants and investigate the possibility of temporary auditory neuropathy in infants. Materials & Methods In this comparative analytical study, twenty premature infants were randomly selected for hearing tests using auditory brainstem response and transient otoacoustic emissions at the time of discharge and three months after the first evaluation. The different components of these tests were analyzed and compared before and after developing the auditory system. Results The OAEs test showed a signal-to-noise ratio above six dB with appropriate amplitudes in all infants. The grand average waveform of the ABR showed a significant difference between the amplitudes of waves III and V before and after maturation in both ears (p<0.05). In addition, the absolute latency of waves, specifically III and V, showed a significant difference between the two assessment times (0.05). Conclusions The present study confirmed the occurrence of temporary ANSD or delayed maturation in premature infants following the lack of complete growth and myelination of auditory nerve fibers. There is a need to determine the hearing status of premature infants by frequent examinations and prevent any unnecessary prescription of amplifications.

Abstract
Disease from nicotine dependency continues to be a leading cause of preventable death worldwide, and therefore research that elucidates potential correlates of tobacco use may facilitate the advancement of research, clinical practice, and policy in this area to target this public health challenge. One potential tobacco use correlate is obsessive-compulsive disorder (OCD) phenomena. The growing research evidence on the association between tobacco use and OCD phenomena is mixed, making it difficult to synthesize extant findings into meaningful conclusions. Indeed, there has never been a systematic review or meta-analysis of this area of research. To this end, a systematic review was carried out with studies between 1988 and 2021, and from this review, 71 independent estimations (n = 10,475; Females = 51.95%; mean age = 37.29, SD = 13.78) were extracted for meta-analysis. We found that about three in ten participants with OCD are likely to use tobacco, which is higher than the general population. The prevalence was the same among OCD participants at all levels (those with symptomology but no confirmed diagnosis, those surpassing a clinical cutoff for OCD but no confirmed diagnosis, and those with a confirmed OCD diagnosis). The results also indicated considerable variability across study results and a wide confidence interval associated with the tobacco use prevalence rate among those with OCD phenomena. The findings provide support for continued study of this comorbidity, perhaps with longitudinal and experimental designs to test for reciprocal associations between tobacco use and OCD phenomena in the service of targeting nicotine dependence as a substantial global public health concern.

Abstract
Coronavirus disease-19 (COVID-19) has led to the demise of millions of people worldwide; additionally, it has resulted in a significant economic and mental health burden. Since the onset of the COVID-19 pandemic, various measures have been constructed to evaluate pandemic-related fear and anxiety. The COVID-19 Anxiety Syndrome Scale (C-19ASS) is a promising measure that assesses coping strategies (e.g., avoidance, checking, worrying and threat monitoring), termed 'COVID-19 Anxiety Syndrome', in response to COVID-19 fear and anxiety. The measure has been broadly welcomed, leading to its use in Brazil (Portuguese), China, Greece, Indonesia, the Philippines, Iran (Farsi), Italy, Saudi Arabia (Arabic), Turkey, the United Kingdom and the United States. To gain a better understanding of the relevance of the COVID-19 Anxiety Syndrome, we conducted a systematic review and meta-analysis to explore the psychological correlates and psychometric properties of the C-19ASS. Through the analysis of a total of 17,789 individuals (age range 19-70; female = 33%-85%), the C-19ASS demonstrated a consistent factor structure, measurement invariance across gender and acceptable reliabilities. Furthermore, a significant association with COVID-19 anxiety, depressive symptoms, generalized anxiety, health anxiety, psychological distress and functional impairment (work and social adjustment) during the COVID-19 pandemic was observed. When considering the Big Five personality traits, the C-19ASS and its subscales were only significantly and negatively associated with extraversion; only the total score on the measure was associated with neuroticism. The observed effect sizes ranged from very small to medium. Given that all included studies (K = 24) were cross-sectional, and due to the nature of the COVID-19 Anxiety Syndrome, which may well persist after the pandemic ends, it is recommended to continue screening society for the persistence of this syndrome.

Abstract
In Greece, the COVID-19 pandemic was associated with social isolation, economic crisis, considerable unemployment, and an escalation of psychological distress. Given the potential of COVID-19 to engender a long-lasting impact on mental health, validating the COVID-19 Anxiety Syndrome Scale (C-19ASS) may be beneficial in determining if fear-based behaviors may persist post-pandemic. This is a psychometric study examining the C-19ASS features across a general sample of Greeks (n = 912; female = 78%; mean age = 32.35, ±9.25). The Greek C-19ASS demonstrated a two-factor structure consistent with the original scale's perseveration and avoidance subscales. This structure was supported by confirmatory factor analysis, which demonstrated a strong fit and robust reliability along with good divergent and convergent validity evidenced by correlational analyses. The incremental validity test revealed that the Greek C-19ASS predicted functional impairment and COVID-19 anxiety independently of health anxiety, generalized anxiety, and depressive symptoms, the Big Five personality traits, pandemic-related factors, and demographic variables. The findings were discussed using a self-regulatory executive function model as a theoretical background to discuss this pandemic-related phenomenon.

Abstract
Background The association between problematic Smartphone use (PSU) and sleep disturbance is evidenced in the literature, but more research is required to investigate the potential factors that may influence the effect of PSU on sleep disturbance. Given the considerable prevalence of PSU (9.3 to 36.7%) and sleep disturbance (55.2%) in Iran, the current study sought to examine an interactional model to test whether metacognitions about Smartphone use, desire thinking (verbal perseveration and imaginal prefiguration), and emotion regulation (expressive suppression and cognitive reappraisal) could have a moderating effect on the above-mentioned association. Method This present study is a cross-sectional, observational study that was conducted between June and September 2022 in a convenience sample of Iranians (n = 603, Female = 419, Age = 24.61 ± 8). Results Despite the significant association between metacognitions about the Smartphone use, PSU, and sleep disturbance, metacognitions failed to predict sleep disturbance above PSU. A slope analysis showed, however, that a high (not low or moderate) levels of imaginal prefiguration strengthen the association between PSU and sleep disturbance, while a high (not low or moderate) level of cognitive reappraisal and expressive suppression dampen the PSU-sleep disturbance association. We also found that verbal perseveration and expressive suppression were unique predictors of sleep disturbance, while imaginal prefiguration and reappraisal only predicted sleep disturbance if they interacted with PSU. Conclusion Theoretically, findings suggest that enhancing cognitive reappraisal (by 1 SD) and reducing imaginal prefiguration (by 1 SD), might protect against sleep disturbance by reducing its association with PSU. Limitations and future directions are discussed.

Abstract
Tropical theileriosis is a protozoan infection caused by Theileria annulata, which significantly affects cattle worldwide. This study was aimed to analyze the TaSPAG1 protein and design a novel multi-epitope vaccine candidate. Online tools were employed for the prediction of Physico-chemical properties, antigenicity, allergenicity, solubility, transmembrane domains and signal peptide, posttranslational modification (PTM) sites, secondary and tertiary structures as well as intrinsically disordered regions, followed by identification and screening of potential linear and conformational B-cell epitopes and those peptides having affinity to bind bovine major histocompatibility complex class I (MHC-I) molecules. Next, a multi-epitope vaccine construct was designed and analyzed. This 907-residue protein was hydrophilic (GRAVY: -0.399) and acidic (pI: 5.04) in nature, with high thermotolerance (aliphatic: 71.27). Also, 5 linear and 12 conformational B-cell epitopes along with 8 CTL epitopes were predicted for TaSPAG1. The 355-residue vaccine candidate had a MW of about 35 kDa and it was antigenic, non-allergenic, soluble and stable, which was successfully interacted with cattle MHC-I molecule and finally cloned into the pET28a(+) vector. Further wet studies are required to assess the vaccine efficacy in cattle. Supplementary Information The online version contains supplementary material available at 10.1007/s40203-023-00153-5.

Abstract
Social networking sites are widespread worldwide, and Facebook is the leading platform in terms of the number of users, laying the ground for potential problematic use. However, problematic Facebook use does not occur for most users but only for a minority. Previous research has found an association between the Big-five personality traits and problematic Facebook use, but the direction of these associations remains controversial. We aimed to fill this gap in knowledge through a systematic review and meta-analysis comprising 425 effect-sizes (78 studies) and 39,930 individuals (females = 33 % to 89 %; age range = 17 to 48 years). Extraversion and neuroticism were associated with higher daily and weekly hours spent on Facebook, while conscientiousness was negatively associated with higher daily hours and not weekly hours. However, when time spent on Facebook was assessed by validated questionnaires, different patterns of associations were observed. Except for the non-significant role of extraversion, the other personality traits were negatively associated with problematic Facebook use, while neuroticism was positively associated. When using different assessment tools was considered, extraversion remained non-significant, but different association patterns were observed. Moreover, for compensatory Facebook use, all personality traits were negatively associated with it, whereas neuroticism exhibited a positive association. Different patterns of associations in terms of strength and direction were observed depending on samples and measures characteristics; thus, definitive conclusions on the direction of the associations are impossible to draw at present. A more robust conceptualization and assessment of problematic Facebook use, as well as time spent on it, is required. Implications, limitations, and future directions are discussed.

Abstract
Background Background: Because of functional and structural similarities between the cochlea and vestibular sensory receptors, vestibular dysfunction could be accompanied by noise-induced hearing loss (NIHL) due to occupational noise exposure. We aimed to evaluate the occurrence of vestibular dysfunction (VD) in individuals with NIHL and occupational noise exposure. Methods A systematic literature research was carried out within the databases of PubMed, Scopus, Science Direct, and Web of Science for published articles between 1980 and Jan 5, 2023 using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The methodological quality of the included systematic reviews was assessed with the Joanna Briggs Institute (JBI) checklist. Vestibular system dysfunction parameters were considered as primary outcomes in subjects with NIHL. Results We reviewed the evidence (from 19 eligible articles) for VD from noise-induced damage to peripheral vestibular structures. VD can occur after occupational noise exposure or concomitantly with NIHL. Furthermore, this study showed that the saccular organ has a higher susceptibility to noise damage than the vestibular organs of the utricle and semicircular canals (SCCs). Conclusion Our results support the role of occupational noise exposure and NIHL as risk factors for developing VD. Further research is needed to investigate the association between the occurrence of VD due to occupational noise exposure or concomitantly with NIHL.

Abstract
Tinnitus is a symptom of various disorders that affects the quality of life of millions people. Given the significance of the access to an objective and non-invasive method for tinnitus detection, in this study the auditory brainstem response (ABR) electrophysiological test was used to diagnose salicylate-induced tinnitus, in parallel with common behavioral tests. Wistar rats were divided into saline (n = 7), and salicylate (n = 7) groups for behavioral tests, and salicylate group (n = 5) for the ABR test. The rats were evaluated by pre-pulse inhibition (PPI), gap pre-pulse inhibition of the acoustic startle (GPIAS), and ABR tests, at baseline, 14 and 62 h after salicylate (350 mg/kg) or vehicle injection. The mean percentage of GPIAS test was significantly reduced following salicylate administration, which confirms the induction of tinnitus. The ABR test results showed an increase in the hearing threshold at click and 8, 12, and 16 kHz tones. Moreover, a decline was observed in the latency ratio of II-I waves in all tone burst frequencies with the highest variation in 12 and 16 kHz as well as a decrement in the latency ratio of III-I and IV-I only in 12 and 16 kHz. ABR test is able to evaluate the salicylate induced tinnitus pitch and confirm the results of behavioral tinnitus tests. GPIAS reflexive response is dependent on brainstem circuits and the auditory cortex while, ABR test can demonstrate the function of the auditory brainstem in more details, and therefore, a combination of these two tests can offer a more accurate tinnitus evaluation.

Abstract
Patients with tinnitus experience difficulties in cognitive control and executive functions. Many of which are regarded as the cause of tinnitus rather than its complications. Methods for the improvement of inhibitory and cognitive control seem to be effective in the control of tinnitus. In this study, transcranial direct current stimulation and auditory Stroop exercise were have been to improve inhibitory control and the ability to ignore tinnitus in patients suffering from chronic tinnitus. 34 patients with chronic tinnitus (> 6 months) were randomly divided into two groups. The first group consist of 17 patients who received 6 sessions of tDCS followed by 6 sessions of auditory Stroop training. The second group received 6 sessions of sham tDCS followed by 6 sessions of auditory Stroop training. The initial evaluations including pure tone audiometry, psychoacoustic measurements, tinnitus handicap inventory (THI) survey and visual analog scale (VAS) of annoyance and loudness were performed before, immediately after, and one month after the tDCS, sham, and Stroop training. The results of this study revealed a significant reduction in THI score, VAS of loudness, and annoyance of tinnitus. A significant correlation was detected between the reaction time of incongruent words in the Stroop task and improvement of THI score and VAS of annoyance. Combined tDCS and Stroop training efficiently improve chronic tinnitus.

Abstract
Correlated to the neutron total reflection phenomenon is the so-called frustrated total reflection, also known as neutron channeling, observed with both thermal and cold neutrons. Within this contribution, such a phenomenon is validated in various additional distinctive Fabry–Pérot nano-resonating configurations; namely in: (i) dual reflection and transmission neutron Fabry–Pérot nano-resonator (Ni/V/Ni/Si substrate), (ii) isotope-based neutron Fabry–Pérot nano-resonator (58Ni/62Ni/58Ni/Silicon substrate), and (iii) multilayered neutron Fabry–Pérot nano-resonator of 8 superposed (B4C/Ti/B4C) single nano-resonators. While such Fabry–Pérot nano-resonators allow effective neutron trapping, the precision of the trapping time of free neutrons in such nano-resonators is governed by the Heisenberg uncertainty and hence offers, a priori, an additional attractive precise approach for potential lifetime investigations. Depending on the configuration of the Fabry–Pérot nano-resonators and the available cold neutron beam, the trapping time is found to be within the temporal regime of 3 to 19 ps. While the main intention of this contribution is to validate the possibility of trapping cold neutrons in nano-structured Fabry–Pérot resonators with a picosecond precision in various configurations, it is hoped that these preliminary results will attract the interest of the neutron lifetime community specifically and the neutron scattering community in general. The potential integration of such trapping method into the bottle or beam methods would elucidate the origin of the difference in neutron lifetime between the two approaches.

Abstract
Background: The antioxidant activity of Bane (Pistacia atlantica) has been proved in different researches. This study evaluated the potential of Bane (Pistacia atlantica) essential oil (as a natural antioxidant) on the oxidative stability of sunflower oil.
Methods: The essence of Bane was added to sunflower oil at concentrations of 200, 400,600,800, and 1,000 ppm. Tertiary Butyl Hydroquinone (TBHQ) was applied as synthetic antioxidant. All samples with the control were stored at 65 ̊C for 20 days. Gas Chromatography-Mass Spectrometry was used for the essence analysis. The 2,2-diphenyl-1-picrylhydrazyl radical scavenging assay, rancimat, p-anisidine value (P-AnVs), and peroxide value (PV) were determined to assess the efficacy of differecnt concentration of essence (200, 400,600,800, and 1,000 ppm). Data were analyzed by Statistical Analysis System (SAS) version 9 Software.
Results: The essential oil yield was 0.1% v/w. The basic components of essence were monoterpene and sesquiterpene hydrocarbons. Synthetic antioxidant had the highest scavenging activity, followed by the mixture sample. PVs were in the range of 19.56-20.73 milliequivalents (meq)/kg for the treated samples after 20 days, while it was 38.74 on the 20th day for the control. For all treatments, PV was increased with increasing storage time. P-AnVs were 8.58-17.14 for stabilized samples and 18.02 for control sample on the 20th day of storage. In all stages, control sample had the highest P-AnV. For all samples, P-AnV increased as a subject of storage time.
Conclusion: P. atlantica (Bane) essential oil had a stabilizing effect on sunflower oil and can be used as a natural antioxidant to stabilize edible oil during storage.

Abstract
This study describes a molecular dynamics computational modelling informed bioengineering of nano-scaled 2-D hydronium jarosite. More specifically, a phyto-engineering approach using green nano-chemistry and agro-waste in the form of avocado seed natural extract was utilized as a green, economic, and eco-friendly approach to synthesize this unique mineral at the nanoscale via the reduction of iron (II) sulphate heptahydrate. The nanoproduct which was found to exhibit a quasi-2D structure was characterized using a multi-technique approach to describe its morphological, optical, electrochemical, and magnetic properties. Radial distribution function and electrostatic potential maps revealed that flavone, a phenolic compound within the avocado seed natural extract, has a higher affinity of interaction with the nanoparticle's surface, whilst vanillic acid has a higher wetting tendency and thus a lower affinity for interacting with the hydronium jarosite nanoparticle surface compared to other phytoactive compounds. XRD and HRTEM results indicated that the nanoscale product was representative of crystalline rhombohedral hydronium jarosite in the form of quasi-triangular nanosheets decorated on the edges with nanoparticles of approximately 5.4 nm diameter that exhibited significant electrochemical and electroconductive behaviours. Magnetic studies further showed a diamagnetic behaviour based on the relationship of the inverse susceptibility of the nanomaterial with temperature sweep.

Abstract
The aim of the present study was to investigate social media use metacognitions through the development of a new scale, the Metacognitions about Social Media Use Scale (MSMUS). In addition, the study included measures of problematic social media use (PSMU), gaming metacognitions, and gaming disorder (GD) to test concurrent validity. A total of 2390 Iranian adolescents (835 males and 1555 females) aged between 13 and 18 years (M = 16.01 years, SD = 1.38) participated in a cross-sectional online survey. The results of the exploratory factor analysis (n = 1195) and confirmatory factor analysis (n = 1195) suggested that the MSMUS (i) can optimally assess metacognitions concerning social media, and (ii) has a two-factor structure ("negative metacognitions about social media" and "positive metacognitions about social media"). The scale was found to be measurement invariant among males and females, and among individuals with and without risk for PSMU. Social media metacognitions presented significant and predominantly (i) moderate correlations with PSMU symptom severity, and (ii) weak correlations with GD symptom severity. Furthermore, positive and negative social media metacognitions had significant and positive predictive effects on the presence of risk for PSMU with and without a risk for GD - even over the effects of age, gender, and gaming metacognitions. This finding may indicate that metacognitions are possibly a transdiagnostic variable which might be helpful in developmentally assessing addictive behaviors, especially negative metacognitions which might be a risk factor for co-occurring addictive behaviors.

Abstract
The current study aimed to investigate the mediating role of cognitive attentional syndrome (CAS) and distress tolerance in the relationship between health-related metacognitions and coronavirus anxiety. The sample of this study consisted of 462 participants (381 female). Participants voluntarily completed self-report questionnaires on each of the variables mentioned above. The results of the structural modeling analysis showed that health-related metacognitions have a significant effect on the mediator variable of distress tolerance and CAS. Also, health-related metacognitions had a direct effect on coronavirus anxiety. Also, based on the results of the bootstrap test, it can be argued that health-related metacognitive beliefs, apart from their direct effect, play an important role in coronavirus anxiety, with CAS acting as a mediator. This study provides insights into the relationships among metacognitive beliefs, coronavirus anxiety, CAS, and distress tolerance. In particular, dysfunctional metacognitive beliefs, including an individual's beliefs about the uncontrollability of disease-related thoughts, are risk factors that could negatively affect mental health, leading to coronavirus anxiety. In addition, the association of dysfunctional beliefs with maladaptive behaviors resulting from the cognitive attentional syndrome is also involved in predicting and causing coronavirus anxiety. Given the insignificant role of emotional distress tolerance in the psychopathology of COVID-19 anxiety, the findings emphasize the importance of cognitive factors in this context.

Abstract
Background The coronavirus disease (COVID-19) pandemic has dramatically changed the health and wellbeing of children. Therefore, this study aimed to investigate the relationship between the home environment and the environmental characteristics on 5-18 years old children health in Iran. Method An online survey was conducted among parents of children aged 5 to 18 living in large cities in Iran in 2021. The statistical population of this cross-sectional study was 500 people. In this survey, questionnaires on the quality of the home environment, exterior and interior landscapes of homes, and the Child Health Questionnaire (CHQ) were used to investigate the relationship between the home environment and environmental characteristics on 5-18 years old children health during the COVID-19 pandemic. The t-test and analysis of variance were used in SPSS 24, and the structural equation modeling (SEM) was utilized in AMOS 24 for analyzing the data. Results The average age of respondents was 37.13 ± 7.20, and that of children was 11.57 ± 3.47. 73.02% of the families were covered by insurance, and 74.08% of them lived in the metropolis. In addition, 65.04% of the families complied with the restrictions of the quarantine period. A share of 31% of the families live in villas, and 55% paid more attention to cleaning their homes during the COVID-19 pandemic than before. A positive and significant statistical relationship (β = 0.414, p < 0.001) was observed between the residence environment and child health. Thus, explained 17.5% of variations in child health. Conclusion The results showed that the children who lived in homes with an exterior landscape in nature had better health. In addition, the 5-18 years old children whose home landscape was a garden, compared to the other two groups (yard, balcony), had better health. Gardens are a potential source of health and not necessarily replaced by other natural environments, thus providing them along with green space is one of the crucial issues that should be considered.

Abstract
Cervical myofascial pain syndrome with dizziness (CMPS-D) has always faced the challenges of evaluation, diagnosis, and etiology. Vestibular-evoked myogenic potentials (VEMPs) are applicable to evaluate the functions of the vestibular system, especially the saccule. The Sound evoked triceps myogenic potentials (SETMPs) have different anatomical efferent connections from Sternocleidomastoid (SCM)-VEMPs. The present study aimed to evaluate the SETMPs and SCMVEMPs in CMPS-D group and compare the results with the control group. We tested 15 participants with CMPS-D with 15 participants in the control group using SCMVEMP and SETMP tests. All participants had normal hearing and vestibular functions. The SCMVEMP response was absent in 4 of 15 patients with CMPS-D, and the mean response CMPS-D group was significantly lower than the control group. There were the SETMP and SCMVEMP responses in all participants in the control group. In CMPS-D subjects with false absent SCMVEMP response, SETMP tests are suitable alternatives for the saccule evaluation, and diminished SCMVEMP in the CMPS-D subjects may not necessarily mean the saccular injury. Furthermore, the involvement of spinal cord pathways is not a cause of dizziness in CMPS-D patients.

Abstract
Background Deficit in cognitive functions and central executive function is one of the popular hypotheses on the underlying cause of tinnitus. Some studies expressed the effect of tinnitus on the inhibitory cognitive tasks, referring to the slower inhibitory results such as in the Stroop task in the people suffering from tinnitus as compared to normal subjects. Since Stroop engages the network overlapping the attention and tinnitus distress networks, it seems likely that Stroop exercises can effectively contribute to controlling the tinnitus and its consequent distress through improvement of the cognitive function and increasing the physiological inhibition. Method A total of 25 patients with chronic tinnitus (> 6 months) were randomly divided into two groups: an intervention group of 15 patients and a control group of 10 patients. Both groups were subjected to initial evaluations including pure tone audiometry, psychoacoustic measurements, tinnitus handicap inventory (THI) survey, and visual analogue scale (VAS) of annoyance and loudness. The intervention group underwent a rehabilitation program consisting of 6 Stroop training sessions. The control group didn't receive any training. Afterwards, both groups were reevaluated and the results were compared to those of initial evaluations. Results Results of this study indicated significant differences in THI scores and VAS of annoyance, before and after Stroop training in the intervention group, although no significant difference was observed when it came to VAS of loudness. Conclusion Successive sessions of conflict processing training can improve the annoyance of tinnitus by enhancing the patient's inhibition control, making this task a safe practice for tinnitus treatment.

Abstract
This study aimed to develop fortified dairy desserts containing Lactobacillus casei and evaluate the physicochemical, sensory, and microbiological characteristics of the product during 28 days of storage. Seven dairy desserts were formulated by date extract (8%), whey protein (1.56%), inulin (4%(, folic acid (0.00066%), vitamin D (0.002%) and gluconate calcium (0.66%). The addition of date extract and inulin increased total solids while whey protein incorporation into dairy desserts led to the improvement of protein and phosphorous content. Furthermore, all fortified dairy desserts showed higher antioxidant activity and total phenolic content. Fortification of dairy desserts had no negative effect on the sensory acceptability and syneresis was not observed. In addition, the pH reduction and increased acidity did not adversely affect the count of L. casei, which remained above 8 log CFU g-1 during storage. Consequently, the fortified dairy dessert developed in this research is an innovative food product with good acceptability and high nutritional quality.

Abstract
Objective: This study aimed to explore the structural relation of emotional schemas with psychological distress and evaluate the mediating role of resilience and cognitive flexibility in this relationship. Method : Participants were 300 students that voluntarily completed a questionnaire package that included the Leahy Emotional Schema Scale (LESS-P), Connor-Davidson Resilience Scale (CD-RISC), Cognitive Flexibility Inventory (CFI), and Depression Anxiety Stress Scale (DASS-21). Then, we utilized the LISREL software for structural equation modeling. Results: Structural equation modeling and path analysis revealed the direct effects of adaptive and maladaptive emotional schemas on psychological distress. The results indicated that maladaptive emotional schemas indirectly affected psychological distress via resilience and cognitive flexibility (P < 0.01). In contrast, adaptive emotional schemas indirectly affected psychological distress via cognitive flexibility rather than resilience (P < 0.05). Evaluation of the proposed structural model revealed an acceptable fit. Conclusion: The present research findings show the effect of emotional schemas on psychological distress via resilience and cognitive flexibility. Furthermore, the results suggest that resilience partially mediates the relationship between emotional schemas and psychological distress. At the same time, cognitive flexibility mediated this relationship.

Abstract
Background and Aim: Occupational noise exposure is considered the second most common risk factor in the industry, which results in auditory and non-auditory health effects. The possibility of cognitive decline as one of the non-auditory health effects may be associated with noise-induced hearing loss (NIHL). This study aimed to investigate the cognitive decline among textile workers with NIHL.
Methods: A total of 30 male textile workers (mean age: 41.2±4.1 years and mean years of noise exposure: 18.9±5.4 years) with symmetrical NIHL (mean 49.3±4.5 dB at 4 kHz) and 30 healthy male textile office staff (aged-matched) with normal hearing and no history of noise exposure were included in this study. Exclusion criteria were included any deficit in ear function, neurological problems, and head trauma. Hearing thresholds were obtained by air and bone conduction audiometry. Workers’ cognitive performance was investigated by two psychological tests: Corsi block and Stroop tests.
Results: The Corsi block indicators including block span (p=0.022) and visuospatial working memory (p=0.002) showed a significant difference between the two groups. Also, the Stroop test indicators including total test time (p<0.001) and response time (p<0.001) showed a significant difference between the two groups. Multiple linear regression analyses showed that workers with a higher hearing threshold at 3 kHz had a lower cognitive performance from both tests.
Conclusion: Our findings support the role of NIHL as a risk factor of developing cognitive decline in textile workers.

Abstract
Non-adherence to medical regimens among patients with diabetes is a well-recognized concern in health care. Modified information, motivation, behavioural skills (IMB) model by adding an emotion component to it was tested to explore predictors of treatment adherence among 1,125 Iranian patients with diabetes type I (T1D) and type II (T2D) and due to other medical conditions. The modified IMB model explained 35% of the treatment adherence with large effect-sizes f2 = 0.56 to 0.69. Self-compassion and interpersonal communication between staff and patients (ICSP) were significant predictors of treatment adherence among patients with T1D, T2D and diabetes due to other medical conditions, while both outperformed the other significant predictors of treatment adherence, i.e., illness perception and social support in all groups. Distress intolerance was a significant predictor of treatment adherence only in patients with T2D. In addition, patients, based on their type of diabetes, exhibited different patterns of illness perception in predicting treatment adherence. Among T2D patients and those with diabetes due to other medical conditions, gender (male; only in T2D) and being single were significant predictors of treatment adherence, while age and diabetes duration were not. Finally, the model demonstrated that above and beyond demographic features, self-compassion, interpersonal communication between patients and health care staff, distress intolerance, perceived social support and illness perception were significant predictors of treatment adherence among patients with diabetes.

Abstract
Background and Aim: The deficit in cognitive functions and central executive function is one of the popular hypotheses on the underlying cause of tinnitus. These factors are not only the complications of tinnitus but are also involved in the generation of it. In this study, bifrontal transcranial Direct Current Stimulation (tDCS) and conflict processing will be used in the form of auditory Stroop training to improve cognitive performance and inhibition control for tinnitus management.
Methods: This study will be carried out on 34 chronic tinnitus patients. The initial evaluations include the tinnitus psychoacoustic evaluations, determination of the tinnitus handicap through tinnitus handicap inventory, and examining the annoyance and loudness of tinnitus through the visual analog scale after which the participants will be investigated in two groups. The first group will receive sessions of tDCS followed by six sessions of conflict processing training. The second group will first receive tDCS in the form of sham, to be followed by six sessions of auditory Stroop. The evaluations will be repeated after each intervention.
Discussion: Studies have shown that successive sessions of conflict processing training can enhance cognitive plasticity and inhibition function. As conflict processing training has not been addressed as rehabilitation training in the people suffering from tinnitus, these processes will be designed in four tasks as rehabilitation exercises in Farsi language and applied along with tDCS to the people with chronic tinnitus to decrease and control tinnitus by improving cognitive and inhibition control.

Abstract
While room temperature bulk mercury is liquid, it is solid in its nano-configuration (Ønano-Hg ≤ 2.5 nm). Conjugating the nano-scale size effect and the Laplace driven surface excess pressure, Hg nanoparticles of Ønano-Hg ≤ 2.4 nm embedded in a 2-D turbostratic Boron Nitride (BN) host matrix exhibited a net crystallization at room temperature via the experimentally observed (101) and (003) diffraction Bragg peaks of the solid Hg rhombohedral α-phase. The observed crystallization is correlated to a surface atomic ordering of 7 to 8 reticular atomic plans of the rhombohedral α-phase. Such a novelty of size effect on phase transition phenomena in Hg is conjugated to a potential Hg waste storage technology. Considering the vapor pressure of bulk Hg, Room Temperature (RT) Solid nano-Hg confinement could represent a potential green approach of Hg waste storage derived from modern halogen efficient light technology.

Abstract
Despite recent advances in the treatment of breast cancer (BC), it still remains as a prevalent and deadly cancer in the world. Given that BC is a heterogeneous disease, it is necessary to clarify molecular mechanisms in tumor cells to improve various therapy outcomes and overcome therapy resistance. Autophagy represents one of the most important intracellular degradation pathways involved in diverse biological processes and plays an important bi-directional role in tumor formation and progression. Among the several mechanisms that affect autophagy, microRNAs (miRNAs) play a crucial role as gene regulators. Several in vivo and in vitro studies have reported multiple miRNAs regulating autophagy in BC that affect tumor initiation, progression, and response to various therapies. In the present review, we highlighted the mechanisms through which miRNAs regulate autophagy in BC and their potential use as therapeutic targets.

Abstract
BACKGROUND Poor sleep quality is associated with a broad range of psychopathology and is a common problem among college students. This study aimed to investigate the mediating role of metacognitive beliefs related to sleep, emotion regulation and a negative cognitive style related to anxiety (looming cognitive style) in the relation between neuroticism and reported sleep quality. PARTICIPANTS Participants were 343 undergraduates from three universities in Tehran (56.3% females, Mean age = 22.01 ± 2.74 years). METHOD Data were gathered with a questionnaire packet that included the Pittsburgh Sleep Quality Index (PSQI), Metacognitions Questionnaire-Insomnia (MCQ-I), Emotion Regulation Questionnaire (ERQ), Looming Maladaptive Style Questionnaire (LMSQ) and Neuroticism subscale of NEO-PI-R. RESULTS Structural equation modeling analyses supported a proposed model (R2 = 37%) which proposed that neuroticism both directly and indirectly linked to reported sleep quality through metacognitions related to sleep, cognitive reappraisal and looming cognitive style (χ2 = 1194.87, p < .001; CFI = 0.93, NFI = 0.90, RMSEA = 0.065, GFI = 0.92, SRMR = 0.069, IFI = 0.93). CONCLUSIONS The results provide evidence for the impact of neuroticism on reported sleep quality through metacognitive, cognitive and emotional factors. The result suggest that special attention should be paid to these factors in the treatment and psychopathology of sleep quality.

Abstract
INTRODUCTION Cyberchondria is excessive seeking for online health-related information related to increasing health anxiety and distress levels. The current study investigated the mediating role of health-related metacognition, cognitive bias, and emotion dysregulation in the relationship between personality traits and cyberchondria. METHODS Participants were 703 individuals 18+ years old who had access to the internet (males = 43.8%, mean age = 33.82 ± 10.09 years and females = 56.2%, mean age = 34.37 ± 11.16 years). They voluntarily completed a questionnaire package that included the Cyberchondria Severity Scale (CSS), the revised NEO Personality Inventory (NEO-PI-R), the Difficulties in Emotion Regulation Scale (DERS), the Meta-Cognitions about Health Questionnaire (MCQ-HA), and the Health Cognitions Questionnaire (HCQ). RESULTS The initial evaluation of the model demonstrated that the personality traits of openness to experience, agreeableness, and conscientiousness had no significant relationship with other variables in the structural model, and the effects of neuroticism and extroversion were the only significant results. Rerunning the model with the removal of non-significant variables revealed a full mediation of health-related metacognition, cognitive bias, and emotion dysregulation in the relation between personality traits (neuroticism and extraversion) and cyberchondria. Fit indices demonstrated the acceptable fit of the model with the collected data (χ2 = 979.24, p <.001; NFI = 0.92, CFI = 0.93, GFI = 0.90, IFI = 0.93, RMSEA = 0.071, and SRMR = 0.063). The results indicated that the present model could explain R 2 = 54% of cyberchondria variance. DISCUSSION These findings suggest that health-related metacognition, cognitive bias, and emotion dysregulation could demonstrate a full mediating role in the correlation between personality traits and cyberchondria.

Abstract
BACKGROUND AND AIMS FoMO has been considered a predisposing factor toward excessive internet use, and a great deal of literature has investigated the link between FoMO and internet use. However, there is still a lack of cohesion in the literature. METHODS The current study have been conducted and reported in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). RESULTS In the current systematic review and meta-analysis of 86 effect-sizes, representative of 55,134 participants (Mean age = 22.07, SD = 6.15, females = 58.37%), we found that the strength of the trait FoMO- internet use association significantly varies from r = 0.11 to r = 0.63. In some populations, FoMO appears to increase with age and it is reverse in other populations. Facebook use was unrelated to FoMO in some populations, and higher FoMO was linked with stopping Instagram use for some individuals. The FoMO- internet use association was independent of their severity, as the interaction was not significant, and this association was neither linear nor curvilinear. The FoMO-internet use association does not appear to be associated with depressive, anxiety, and stress symptoms or level of life satisfaction. The COVID-19 pandemic was the only significant moderator of the FoMO-internet use association, strengthening this relationship. DISCUSSION AND CONCLUSIONS FoMO demonstrates a considerable role in internet use; however, there is no evidence of interaction or bi-directional association between the mentioned. Overall, we still don't know what factors contribute to individuals exhibiting distinct patterns in the FoMO-internet use association.

Abstract
Researchers have found similarities and differences between behavioral and drug addictions. The present study was designed to explore which of a series of psychosocial predictors of addictive behaviors could differentiate problematic Internet use (PIU) and Cannabis Use Disorder (CUD) in a sample of University students. A total of 144 participants (76 males, mean age = 23.03 years ± 2.83) were separated into three groups: those presenting with PIU (18 females, Mean age = 22.27 years), those presenting with CUD (22 female, Mean age = 22.73 years), and a control group (28 female, Mean age = 24.04 years). Participants completed the Internet Abusive Use Questionnaire (IAUQ), the Severity of Dependence Scale (SDS), the Multidimensional Scale of Perceived Social Support (MSPSS), the Barratt Impulsiveness Scale-11 (BIS-11), the Multidimensional Distress Tolerance Scale (MDTS), the Emotion Regulation Questionnaire (ERQ), the Metacognitions Questionnaire-30 (MCQ-30), and the Repetitive Thinking Questionnaire-10 (RTQ-10). The classification analysis results showed that 68.8% of the control group, 70.8% of the PIU group, and 81.3% of the CUD group were correctly classified in their respective groups. In addition, the results of the discriminant function analysis showed that there was a significant difference between members of the PIU and CUD groups in the degree of family support (0.45), significant other (0.33), tolerance of physical discomfort (0.30), reappraisal (0.42), and cognitive confidence (0.35). The findings provide evidence that specific psychosocial predictors can discriminate PIU from CUD.

Abstract
There is a potential for a long-lasting psychological and social impact from the COVID-19 pandemic. Recently, the COVID-19 Anxiety Syndrome Scale (C19-ASS) has been developed, which measures individuals' coping mechanisms in relation to the fear or threat of COVID-19. The C19-ASS was developed and has been used so far only in Western samples. Further psychometric evaluation is needed in ethnically diverse samples. Therefore, the current study sought to test the psychometric properties in a large sample of Iranians (n = 1429; female = 52.1%; Mean age = 35.83, ±12.89) who completed a cross-sectional survey. Exploratory factor analysis revealed that the Persian C19-ASS has a two-factor structure corresponding to the perseveration and avoidance subscales of the original scale. Confirmatory factor analyses also supported a two-factor solution, which showed a firm model fit and high internal consistencies. Furthermore, it showed excellent divergent validity from generalized anxiety, indicating that it is concerned explicitly with COVID-19, supported by correlational analyses and exploratory factor analysis. Test of incremental validity indicated the Persian C19-ASS explained more variance in functional impairment and COVID-19 anxiety than the gender, marital and educational status, generalized anxiety, neuroticism, openness, consciousness and having lost someone close due to COVID-19. Also, based on a mediation test, it was found that C19-ASS mediates the relationship between the Big Five personality traits (except openness and consciousness) and health anxiety, generalized anxiety, depression and COVID-19 anxiety. Overall, the current findings provide further evidence for the construct of the COVID-19 anxiety syndrome. The COVID-19 anxiety syndrome is discussed in light of the S-REF model that provides an explanatory framework for this pandemic-related construct.

Abstract
The global COVID‐19 outbreak has put the human race's distress tolerance abilities to the test. And, the distress experienced getting worse with each pandemic wave; however, the more flexible the person, the greater the chance of surviving. Thus, the current study aimed to examine the mediating role of personalized psychological flexibility (PPF) in the link between distress intolerance to psychological distress during the fourth wave of the pandemic in Iran. A total of 576 individuals (Meanage 34.80, ±10.9, females 55.6%) took part in the online survey. In this national sample, PPF partially played a role in mediating the association mentioned above. Interestingly, this mediation was independent of demographic factors (age, gender, marital status, and educational level) and fear of COVID‐19, mindfulness, and satisfaction with life. So, despite the mentioned variables, accepting and using unpleasant emotions as fuel to achieve valued goals rather than avoiding them would mitigate the psychological distress during the pandemic. Consequently, public health services can aim to provide psychological flexibility enhancing interventions to decay COVID‐19‐related mental distress.
