Abstract
A series of new analogs of 3,5-dihydroxybenzoyl-hydrazineylidene conjugated to different methoxyphenyl triazole (11a-n) synthesized using click reaction. The structures of all synthesized compounds were characterized by FTIR, 1H, 13C-NMR spectroscopy, and CHO analysis. The tyrosinase inhibitory potential of the synthesized compounds was studied. The newly synthesized scaffolds were found to illustrate the variable degree of the inhibitory profile, and the most potent analog of this series was that one bearing 4-methoxyphenyl moiety, and exhibited an IC50 value of 55.39 ± 4.93 µM. The kinetic study of the most potent derivative reveals a competitive mode of inhibition. Next, molecular docking studies were performed to understand the potent inhibitor's binding mode within the enzyme's binding site. Molecular dynamics simulations were accomplished to further investigate the orientation and binding interaction over time and the stability of the 11m-tyrosinase complex.

Abstract
Purpose To evaluate the associations between hearing status and hearing aid use and performance on the Montreal Cognitive Assessment (MoCA) in older adults in a cross-sectional study in Norway. Methods This study utilized data from the fourth wave of the Trøndelag Health Study (HUNT4, 2017-2019). Hearing thresholds at frequencies of 0.5, 1, 2, and 4 kHz (or PTA4) in the better hearing ear were used to determine participants' hearing status [normal hearing (PTA4 hearing threshold, ≤ 15 dB), or slight (PTA4, 16-25 dB), mild (PTA4, 26-40 dB), moderate (PTA4, 41-55 dB), or severe (PTA4, ≥ 56 dB) hearing loss]. Both standard scoring and alternate MoCA scoring for people with hearing loss (deleting MoCA items that rely on auditory function) were used in data analysis. The analysis was adjusted for the confounders age, sex, education, and health covariates. Results The pattern of results for the alternate scoring was similar to that for standard scoring. Compared with the normal-hearing group, only individuals with moderate or severe hearing loss performed worse in the MoCA. In addition, people with slight hearing loss performed better in the MoCA than those with moderate or severe hearing loss. Within the hearing loss group, hearing aid use was associated with better performance in the MoCA. No interaction was observed between hearing aid use and participants' hearing status with performance on the MoCA test. Conclusion While hearing loss was associated with poorer performance in the MoCA, hearing aid use was found to be associated with better performance in the MoCA. Future randomized control trials are needed to further examine the efficacy of hearing aid use on the MoCA performance. When compared with standard scoring, the alternate MoCA scoring had no effect on the pattern of results.

Abstract
Tyrosinase, the rate-limiting enzyme of melanogenesis, plays a crucial role in hyperpigmentation. As a result, in this study, a novel class of thiazolopyrimidine derivatives was developed and synthesized as tyrosinase inhibitor. The structure of derivatives was characterized using various spectroscopy techniques, including FTIR, Mass, 1H-NMR, and 13C-NMR. Next, the inhibitory activities of all derivatives were examined against tyrosinase, and, 6a as the most potent compound, exhibited an IC50 value of 28.50 µM. Furthermore, the kinetic study of 6a was performed to better understand the inhibitory mechanism and its type of inhibition. The UV/Vis spectra analysis was also executed to provide valuable evidence supporting the inhibitory mechanism of compound 6a in the context of tyrosinase inhibition. Also, molecular docking and dynamic molecular study of 6a were executed to study its interactions within the enzyme's binding site.

Abstract
In this pared, an efficient method is introduced for the synthesis of 3-alkyl-2-(((4-(2-oxopropyl)-1H-1,2,3-triazol-1-yl)alkyl)thio)-2,3-dihydroquinazolin-4(1H)-one derivatives. These novel products have both 1,2,3-triazole and quinazolinone in their structures. For the synthesis of these products, a novel catalyst is designed, synthesized, and characterized by the immobilization of copper onto modified magnetic iron oxide. The catalyst (denoted: Cu@Py-Oxa@SPION) was characterized by several characterization techniques. In this regard, 16 3-alkyl-2-(((4-(2-oxopropyl)-1H-1,2,3-triazol-1-yl)alkyl)thio)-2,3-dihydroquinazolin-4(1H)-one derivatives were synthesized in high isolated yields (77-86%). As an advantage, the catalyst is highly recoverable and its activity has not decreased after 7 sequential runs. The method is very efficient for the synthesis of the products in high isolated yields under mild reaction conditions in a green solvent. The scope of the method is broad and several examples were successfully synthesized using starting materials with different functional groups.

Abstract
BACKGROUND Cancer is a leading cause of death worldwide. While routine diagnosis of cancer is performed mainly with biopsy sampling, it is suboptimal to accurately characterize tumor heterogeneity. Positron emission tomography (PET)-driven radiomic research has demonstrated promising results when predicting clinical endpoints. This study aimed to investigate the added value of quantum machine learning both in simulator and in real quantum computers utilizing error mitigation techniques to predict clinical endpoints in various PET cancer patients. METHODS Previously published PET radiomics datasets including 11C-MET PET glioma, 68GA-PSMA-11 PET prostate and lung 18F-FDG PET with 3-year survival, low-vs-high Gleason risk and 2-year survival as clinical endpoints respectively were utilized in this study. Redundancy reduction with 0.7, 0.8, and 0.9 Spearman rank thresholds (SRT), followed by selecting 8 and 16 features from all cohorts, was performed, resulting in 18 dataset variants. Quantum advantage was estimated by Geometric Difference (GDQ) score in each dataset variant. Five classic machine learning (CML) and their quantum versions (QML) were trained and tested in simulator environments across the dataset variants. Quantum circuit optimization and error mitigation were performed, followed by training and testing selected QML methods on the 21-qubit IonQ Aria quantum computer. Predictive performances were estimated by test balanced accuracy (BACC) values. RESULTS On average, QML outperformed CML in simulator environments with 16-features (BACC 70% and 69%, respectively), while with 8-features, CML outperformed QML with + 1%. The highest average QML advantage was + 4%. The GDQ scores were ≤ 1.0 in all the 8-feature cases, while they were > 1.0 when QML outperformed CML in 9 out of 11 cases. The test BACC of selected QML methods and datasets in the IonQ device without error mitigation (EM) were 69.94% BACC, while EM increased test BACC to 75.66% (76.77% in noiseless simulators). CONCLUSIONS We demonstrated that with error mitigation, quantum advantage can be achieved in real existing quantum computers when predicting clinical endpoints in clinically relevant PET cancer cohorts. Quantum advantage can already be achieved in simulator environments in these cohorts when relying on QML.

Abstract
In this study, a new and recyclable biocatalyst (MgAl CO3-LDH@Asn) was synthesized by immobilizing l-asparagine amino acid (Asn) on the surface of 3-(chloropropyl)-trimethoxysilane modified MgAl CO3-layered double hydroxide (LDH). The physicochemical properties of the samples were identified by Fourier transform infrared (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray (EDX), and thermogravimetric analysis (TGA) techniques. The MgAl CO3-LDH@Asn was employed in the multi-component assembly process for the synthesis of tri-substituted derivatives of 2,4,5-(H1)-imidazoles from benzyl, various benzaldehyde derivatives, and ammonium acetate. For optimizing the reaction, the main factors, including the amount of MgAl CO3-LDH@Asn, type of solvent, reaction time, and temperature were evaluated. The optimum conditions of the model reaction were achieved using 20 mg of MgAl CO3-LDH@Asn biocatalyst in ethanol solvent after 20 min at reflux temperature. According to the findings above, the results indicated that high-yield products are achieved within a short time frame. Moreover, the high catalytic activity of the MgAl CO3-LDH@Asn was maintained for four cycles without significantly diminishing its performance.

Abstract
Many devices heavily rely on combinatorial material optimization. However, new material alloys are classically developed by studying only a fraction of giant chemical space, while many intermediate compositions remain unmade in light of the lack of methods to synthesize gapless material libraries. Here report a high-throughput all-in-one material platform to obtain and study compositionally-tunable alloys from solution is reported. This strategy is applied to make all Csx MAy FAz PbI3 perovskite alloys (MA and FA stand for methylammonium and formamidinium, respectively), in less than 10 min, on a single film, on which 520 unique alloys are then studied. Through stability mapping of all these alloys in air supersaturated with moisture, a range of targeted perovskites are found, which are then chosen to make efficient and stable solar cells in relaxed fabrication conditions, in ambient air. This all-in-one platform provides access to an unprecedented library of compositional space with no unmade alloys, and hence aids in a comprehensive accelerated discovery of efficient energy materials.

Abstract
RATIONALE For unambiguous identification of Chemical Weapons Convention (CWC)-related chemicals in environmental and biological samples, access to mass spectra and expertise in spectral interpretation is required. As of today, there is no mass spectrum available for dialkyl alkylarsonodithioites in the literature. Therefore, it is essential to obtain spectral information about these compounds. METHODS CWC-related organoarsenic compounds were synthesized and analyzed by gas chromatography combined with mass spectrometry (MS), and their retention index (RI) was calculated by Van Den Dool's method. The relationship between RI and density functional theory (DFT)-calculated polarizability (⍺) and molecular weight was also studied. Electron ionization (EI) mode was used to investigate the general fragmentation patterns of the synthesized compounds. A DFT analysis of some major fragment ions was performed in order to confirm the fragmentation pathways. RESULTS A linear relationship between RI and ⍺ is observed. The mass spectra of compounds 5-7 are affected by alkyl groups on sulfur and arsenic atoms. The molecular ions of compounds 5-7 can be observed in their EI-MS spectra with relatively good abundance. EI-MS studies revealed some interesting fragmentation pathways, such as the formation of arsenic analogue of benzylic and tropylium cations in EI-MS of chemicals 6. CONCLUSIONS By analyzing the mass spectra and RI values, it is possible to detect CWC-related chemicals in aqueous, blood and urine samples during an on-site or off-site inspection.

Abstract
AIM Revascularisation is a therapeutic approach for treatment of immature teeth with necrotic pulp. The conventional protocol includes application of triple antibiotic paste (TAP). The present study aimed to compare the efficacy of propolis and TAP as intra-canal medicaments for revascularisation of immature teeth in dogs. METHODOLOGY This study was conducted on 20 immature (open-apex) canine teeth in mixed breaded dogs. First, the teeth were exposed to oral environment, followed by intra-canal cleaning and shaping 2 weeks later.. The teeth were divided into two groups. The TAP group received paste comprising of ciprofloxacin, metronidazole, and minocycline (at a concentration of 100 µg/mL), while propolis (15% w/v) was used in the other group. The revascularisation procedure was done by means of sodium hypochlorite, EDTA and distilled water as final irrigant. After dehumidifying and induction of bleeding, mineral trioxide aggregate (MTA) was applied At 6-month follow-up, radiographs were evaluated by two observers regarding root length and thickness, intra-canal calcification, periapical lesions, and apex formation. Data were analysed by the Chi-square and Fisher's exact tests. RESULTS There was no significant difference between the TAP and propolis groups in root length or root thickness increase, calcification, related lesions, or apex formation (P > 0.05). CONCLUSION Findings of the present study in experimental animals revealed that the efficacy of propolis as an intra-canal medicament is comparable to that of triple antibiotic paste for revascularisation therapy.

Abstract
Face-to-face communication is one of the most common means of communication in daily life. We benefit from both auditory and visual speech signals that lead to better language understanding. People prefer face-to-face communication when access to auditory speech cues is limited because of background noise in the surrounding environment or in the case of hearing impairment. We demonstrated that an early, short period of exposure to audiovisual speech stimuli facilitates subsequent auditory processing of speech stimuli for correct identification, but early auditory exposure does not. We called this effect “perceptual doping” as an early audiovisual speech stimulation dopes or recalibrates auditory phonological and lexical maps in the mental lexicon in a way that results in better processing of auditory speech signals for correct identification. This short opinion paper provides an overview of perceptual doping and how it differs from similar auditory perceptual aftereffects following exposure to audiovisual speech materials, its underlying cognitive mechanism, and its potential usefulness in the aural rehabilitation of people with hearing difficulties.

Methods Data were drawn from the fourth wave of the Trøndelag Health Study (HUNT4 Hearing, 2017-2019). The hearing threshold was defined as the pure-tone average of 0.5, 1, 2, and 4 kHz in the better ear. The participants were divided into five groups: normal hearing or slight/mild/moderate/severe hearing loss. Subjective self-reported short-term and long-term memory complaints were measured by the nine-item Meta-Memory Questionnaire (MMQ). The sample included 20,092 individuals (11,675 women, mean age 58.3 years) who completed both hearing and MMQ tasks. A multivariate analysis of variance (adjusted for covariates of age, sex, education, and health cofounders) was used to evaluate the association between hearing status and hearing aid use (in the hearing-impaired groups) and long-term and short-term subjective memory complaints. Results A multivariate analysis of variance, followed by univariate ANOVA and pairwise comparisons, showed that hearing loss was associated only with more long-term subjective memory complaints and not with short-term subjective memory complaints. In the hearing-impaired groups, the univariate main effect of hearing aid use was only observed for subjective long-term memory complaints and not for subjective short-term memory complaints. Similarly, the univariate interaction of hearing aid use and hearing status was significant for subjective long-term memory complaints and not for subjective short-term memory complaints. Pairwise comparisons, however, revealed no significant differences between hearing loss groups with respect to subjective long-term complaints. Conclusion This cross-sectional study indicates an association between hearing loss and subjective long-term memory complaints but not with subjective short-term memory complaints. In addition, an interaction between hearing status and hearing aid use for subjective long-term memory complaints was observed in hearing-impaired groups, which calls for future research to examine the effects of hearing aid use on different memory systems.

Abstract
OBJECTIVES We performed a current study to examine the association between dietary inflammatory index (DII) score and older age-related muscle conditions, including sarcopenia, low muscle mass, low muscle strength, frailty, and/or disability. DESIGN Systematic review and dose-response meta-analysis. SETTING A systematic literature search was performed using Scopus, PubMed/MEDLINE, and ISI Web of Science without limitation until October 04, 2022. Relative risk (RR) and 95% confidence interval (CI) were pooled by applying a random-effects model, while validated methods examined assess quality and publication bias via Newcastle-Ottawa Scale, Egger's regression asymmetry, and Begg's rank correlation tests respectively. A dose-response meta-analysis was conducted to estimate the RRs per 1-unit increment in DII scores. PARTICIPANTS Adults (≥18 years). MEASURES The risk of older age-related muscle conditions (sarcopenia, low muscle mass, low muscle strength, frailty, and/or disability). RESULTS Data were available from 19 studies with 68079 participants. Results revealed that a higher DII score was significantly related to an increased risk of sarcopenia (RR=1.50; 95% CI: 1.26, 1.79; I2=53.3%; p<0.001; n=10; sample size =43097), low muscle strength (RR=1.47; 95% CI: 1.24, 1.74; I2=6.6%; p<0.001; n=4; sample size =9339), frailty (RR=1.61; 95% CI: 1.41, 1.84; I2=0.0%; p<0.001; study=5; participant=3882) and disability (RR=1.41; 95% CI: 1.16, 1.72; I2=58.4%; p=0.001; n=5; sample size =13760), but not low muscle mass (RR=1.24; 95% CI: 0.98, 1.56; I2=49.3%; p=0.069; n=4; sample size =11222). Additionally, results of the linear dose-response indicated that an increase of one point in the DII score was related to a 14% higher risk of sarcopenia, 6% higher risk of low muscle mass, 7% higher risk of low muscle strength, and a 7% higher risk of disability in adults. Non-linear dose-response relationships also revealed a positive linear association between the DII score and the risk of sarcopenia (Pnonlinearity = 0.097, Pdose-response<0.001), frailty (Pnonlinearity = 0.844, Pdose-response=0.010) and disability (Pnonlinearity = 0.596, Pdose-response=0.007). CONCLUSION Adherence to a pro-inflammatory diet was significantly associated with a higher risk of sarcopenia and other age-associated adverse effects such as low muscle strength, disability, and frailty. These results indicate a necessity to prioritize the reduction of pro-inflammatory diets to help promote overall older age-related muscle conditions.

Abstract
Introduction Various transdiagnostic factors have been associated with insomnia severity. The current study aimed to predict insomnia severity based on a group of transdiagnostic factors including neuroticism, emotion regulation, perfectionism, psychological inflexibility, anxiety sensitivity, and repetitive negative thinking after controlling for depression/anxiety symptoms and demographic characteristics. Methods Two hundred patients with chronic insomnia disorder were recruited from a sleep disorder clinic. Participants completed the Insomnia Severity Index (ISI), Clinical Perfectionism Questionnaire (CPQ), Acceptance and Action Questionnaire-II (AAQ-II), Anxiety Sensitivity Index-3 (ASI-3), Repetitive Thinking Questionnaire (RTQ-10), Big Five Inventory (BFI-10), Emotion Regulation Questionnaire (ERQ), and Depression Anxiety Stress Scale (DASS-21). Results After controlling for the confounding variables (depression/anxiety symptoms and demographic characteristics), hierarchical multiple linear regression suggested the significant association of neuroticism (BFI), cognitive reappraisal (ERQ), personal standards (CPQ), evaluative concerns (CPQ), physical concerns (ASI), cognitive concerns (ASI), and repetitive negative thinking (RTQ) with insomnia severity. Discussion The findings support the role of transdiagnostic factors, especially physical concerns, repetitive negative thinking, and neuroticism in chronic insomnia. Future research using longitudinal designs is required to verify the causal status of transdiagnostic variables.

Abstract
PURPOSE Iranians' worry over the number of older patients negatively impacted by COVID-19 surged dramatically throughout the 5 waves of the COVID-19 pandemic, which lasted from January 2020 to September 2021. The goal of this research was to assess the physical and mental health of Iranian older persons throughout the COVID-19 pandemic's major waves. METHODS The health condition of 507 older persons with a positive examination for COVID-19 illness was assessed before and throughout the 5 waves of coronavirus in south Iran in analytical and hybrid longitudinal research. RESULTS The primary consequences of COVID-19 incidence on frailty and mental health issues were revealed in this investigation. Using a linear mixed model, we found a reduction of 0.33 in loneliness (β = -.33, 95% CI -0.39 to -0.26) during the COVID-19 pandemic. The probabilities of becoming depressed, anxious, or frail rose 4.61 (95% CI: 3.77-5.63), 1.85 (95% CI: 1.52-2.24), as well as 1.42 (95% CI: 1.17-1.42) time, subsequently, with COVID-19 occurrence, according to the mixed logistic models. Furthermore, the influence of COVID-19 incidence on loneliness result differs by gender; for depression, it varies by education; and for anxiety, it changes by comorbidities and living independently. CONCLUSION The COVID-19 pandemic significantly impacts the mental health and frailty of older persons with the positive COVID-19 situation, and this scenario is gender-based too.

Abstract
![]()
Thin films are an
integral part of many electronic and optoelectronic
devices. They also provide an excellent platform for material characterization.
Therefore, strategies for the fabrication of thin films are constantly
developed and have significantly benefited from the advent of high-throughput
synthesis (HTS) platforms. This perspective summarizes recent advances
in HTS of thin films from experimentalists’ point of view.
The work analyzes general strategies of HTS and then discusses their
use in developing new energy materials for applications that rely
on thin films, such as solar cells, light-emitting diodes, batteries,
superconductors, and thermoelectrics. The perspective also summarizes
some key challenges and opportunities in the HTS of thin films.

Abstract
ABSTRACT Poor clinical insight is one of the most common features of schizophrenia spectrum disorders and plays a critical role in prognosis and treatment. Considering the biological and phenomenological overlap between schizophrenia and bipolar I disorder with psychotic features (BID) and increasing incidents of methamphetamine-induced psychotic disorder (MIPD) patients in Iran, it is necessary to have a clear picture of insight among these three groups. The aim of the present study was to compare clinical insight and other aspects of illness among three different disorders: schizophrenia, BID, and MIPD. In addition, we sought to examine the relationship of the severity of psychotic symptoms with clinical insight in each group. A total of 115 male inpatients, including 48 persons diagnosed with schizophrenia, 35 persons diagnosed with BID, and 32 persons diagnosed with MIPD, were selected. All participants completed the Scale to Assess Unawareness of Mental Disorder and the Positive and Negative Syndrome Scale. The results of analysis of variance indicated that schizophrenia patients reported higher rates of illness duration and number of hospital admissions in comparison to the MIPD and BID groups. In addition, persons diagnosed with BID reported more of these outcomes than MIPD groups. However, the three groups showed similar patterns in terms of age of onset and educational, marital, and occupational statuses. The results also revealed that awareness of the disorder was more impaired in schizophrenia patients compared with BID and MIPD patients and in MIPD compared with BID groups. However, the level of awareness of the effect of medication, the awareness of social consequences, and the total score of clinical insight were similar across the three diagnostic groups. As expected, poor clinical insight was correlated with high levels of positive, negative, and cognitive symptoms in the schizophrenia group; with high levels of positive, cognitive, and depressive symptoms in the BID group; and with high levels of positive and excitement symptoms in MIPD. In addition, hierarchical linear regression analyses revealed that only cognitive symptoms in the schizophrenia group and excitement symptoms in the MIPD group significantly predicted the overall score of clinical insight. In the BID group, both cognitive and depressive symptoms significantly predicted clinical insight. These findings suggest that there are differing levels of poor clinical insight in schizophrenia, MIPD, and BID and that poor clinical insight found within each group may have different antecedents.

Abstract
To understand the metabolic mechanisms regulating lipid metabolism by monensin, Afshari male lambs (n = 16) with 41.0 ± 2.4 kg body weight (BW, mean ± SD) at approximately 180 days of age were randomly assigned equally to two dietary treatments. After a 21-day pre-adaptation period, all animals in two groups continued to receive the basal diet, but one group received no monensin supplementation (control) while the other group received 30 mg/day of monensin per animal. Individual BW was recorded weekly to determine the average daily body weight gain (ADG). At the end of the 56-day experimental period, lambs were weighed and slaughtered. Monensin supplementation did not affect BW, ADG, and rumen fermentation characteristics. However, monensin significantly downregulated the sterol regulatory element-binding protein (SREBP)-2 gene expression in all sample tissues (p < 0.05). Also, monensin downregulated expressions of SREBP-1c and peroxisome proliferator-activated receptor (PPAR)-γ in back fat tissues. Monensin increased the expression of 3-hydroxy-3-methylglutaryl-CoA synthase (HMGCS)-2, but it decreased the mRNA abundance of HMGCS-1 in the rumen epithelial tissues (p < 0.05). Our data suggest that monensin downregulates cholesterol synthesis via inhibition of HMGCS-1 and impairment of the SREBP pathway, probably due to a crosstalk among different tissues to control energy metabolism.

Abstract
Quantum machine learning has experienced significant progress in both software and hardware development in the recent years and has emerged as an applicable area of near-term quantum computers. In this work, we investigate the feasibility of utilizing quantum machine learning (QML) on real clinical datasets. We propose two QML algorithms for data classification on IBM quantum hardware: a quantum distance classifier (qDS) and a simplified quantum-kernel support vector machine (sqKSVM). We utilize these different methods using the linear time quantum data encoding technique ([Formula: see text]) for embedding classical data into quantum states and estimating the inner product on the 15-qubit IBMQ Melbourne quantum computer. We match the predictive performance of our QML approaches with prior QML methods and with their classical counterpart algorithms for three open-access clinical datasets. Our results imply that the qDS in small sample and feature count datasets outperforms kernel-based methods. In contrast, quantum kernel approaches outperform qDS in high sample and feature count datasets. We demonstrate that the [Formula: see text] encoding increases predictive performance with up to + 2% area under the receiver operator characteristics curve across all quantum machine learning approaches, thus, making it ideal for machine learning tasks executed in Noisy Intermediate Scale Quantum computers.

Abstract
Background: Calculating the burden of diseases is essential for their monitoring. The burden of cardiovascular diseases in Kurdistan Province has not been reported. This study aimed at calculating the burden of cardiovascular diseases in the Kurdistan Province from 2011 through 2017. Methods: In this cross-sectional study, incidence data were extracted from registration systems. The methods of the World Health Organization (WHO) were employed to calculate disability-adjusted life years (DALYs) of cardiovascular diseases in the Kurdistan Province. DALYs were calculated by summing the years of life lost (YLLs) and the years of life lived with disability (YLDs) for sex, age group, and year. Results: The burden of cardiovascular diseases increased from 18569.1 DALYs in 2011 to 34929.8 DALYs in 2017. The highest increase and the largest decrease in DALY according to the all age-standardized DALYs index were related to acute myocardial infarction and heart failure in women, respectively. The highest DALYs in both sexes were in the age group of over 80 years. Conclusion: The burden of cardiovascular diseases is increasing in the Iranian province of Kurdistan. It is, therefore, essential to implement appropriate and adequate interventions such as lifestyle modification, extensive screening, public education promotion, and operational plan development. We hope our results will aid decision-makers in performing urgent interventions.

Abstract
A novel series of phenoxymethybenzoimidazole derivatives (9a-n) were rationally designed, synthesized, and evaluated for their α-glycosidase inhibitory activity. All tested compounds displayed promising α-glycosidase inhibitory potential with IC50 values in the range of 6.31 to 49.89 μM compared to standard drug acarbose (IC50 = 750.0 ± 10.0 μM). Enzyme kinetic studies on 9c, 9g, and 9m as the most potent compounds revealed that these compounds were uncompetitive inhibitors into α-glycosidase. Docking studies confirmed the important role of benzoimidazole and triazole rings of the synthesized compounds to fit properly into the α-glycosidase active site. This study showed that this scaffold can be considered as a highly potent α-glycosidase inhibitor.

Abstract
Background: We aimed at estimating the burden of cancer in Kurdistan Province, western Iran during 2011-2017.
Methods: In this cross-sectional study, incidence data extracted from the cancer registry system and death data were extracted from the system of registration and classification of causes of death of Kurdistan Province. We applied the WHO’ methods to calculate the disability-adjusted life year (DALYs).
Results: The burden of cancer increased from a DALYs of 12309 in 2011 to 13969 in 2017, the YLL from 11644 in 2011 to 12951 in 2017 and the YLD from 665 in 2011 to 1018 in 2017. The top five cancers, according to DALYs (%) in both sex during 2011-2017 were: stomach (25%), lung (14%), liver (9%), esophagus (6%), and colon (6%). The most burden of cancer related to gastrointestinal tract (54% vs. 45%). Totally, more than 25% of DALYs were related to stomach cancer.
Conclusion: The increasing DALYs of cancer in Kurdistan Province is one of the major public health concerns as in most developed countries. More than half of the burden of cancer in the Kurdistan Province is related to gastrointestinal tract. Stomach cancer, is accounting for more than 25% of the burden in both sexes. Urgent policy, management and public health measures such as general education, screening, early detection and effective treatment are recommended to reduce the burden of cancers and especially gastrointestinal tract malignancies.

Abstract
BACKGROUND Dental caries is a significant public health problem in Iran. Teaching minimally invasive interventions in paediatric dentistry may facilitate the provision of treatment for untreated dental caries in children. We evaluated the teaching of such interventions in both undergraduate dental curriculum and Paediatric Dentistry Specialty Training Programme (PDSTP) in Iran. METHODS This was a cross-sectional questionnaire-based survey. Participants in this study were the directors of 40 undergraduate programmes and 15 PDSTPs in all Iranian dental schools (response rate = 100%). Descriptive statistics were reported. RESULTS The most commonly taught methods were preventive fissure sealant and preventive resin restoration (PRR), which were taught 'both didactically and clinically' in all undergraduate dental programmes. The least commonly taught methods were silver diamine fluoride (SDF), the Hall technique and resin infiltration, which were taught 'both didactically and clinically' in less than 5% of dental schools. The same three methods were the least commonly approaches taught in PDSTP, further, they were less often perceived to be 'essential'. CONCLUSIONS There was a notable variation in the teaching of the management of dental caries in Iran's dental education. Some minimally invasive approaches including SDF, the Hall technique and resin infiltration are not being commonly taught in Iranian dental schools despite the evidence base for these techniques.

Abstract
This is a case report of a 13-year old patient presenting with knee pain after a bike accident. Multiple investigations and medical examinations focused on the knee. They did not show any abnormality. About one year later, the patient comes back with increased hip pain, limited internal rotation and shortening of the left limb. Hip X-Ray exams reveal a bilateral slipped capital femoral epiphysis requiring already an osteotomy. Slipped capital femoral epiphysis is a disorder of the proximal femoral epiphysis. The femoral neck is displaced anteriorly and rotates externally while the epiphysis remains in the acetabulum. This pathology is more common in preadolescent boys and can be associated with hormonal disorders. Patients present with an externally rotated gait, a limited internal rotation, associated hip and knee pain. Diagnosis might be missed when patients present with knee pain and can lead to delayed treatment. When facing knee pain, it is essential to perform a clinical examination of the hip. Radiography is the first medical imaging. Surgical treatment by in situ fixation is recommended and prevents further slip with a high rate of success. When delayed, a much more invasive approach is required. A delay in diagnosis adversely affects long-term outcomes.

Abstract
OBJECTIVES The aim of this study was to calculate the burden of stroke in Kurdistan Province, Iran between 2011 and 2017. METHODS Incidence data extracted from the hospital information system of Kurdistan Province and death data extracted from the system of registration and classification of causes of death were used in a cross-sectional study. The World Health Organization method was used to calculate disability-adjusted life years (DALYs). RESULTS The burden of stroke increased from 2453.44 DALYs in 2011 to 5269.68 in 2017, the years of life lost increased from 2381.57 in 2011 to 5109.68 in 2017, and the years of healthy life lost due to disability increased from 71.87 in 2011 to 159.99 in 2017. The DALYs of ischaemic stroke exceeded those of haemorrhagic stroke. The burden of disease, new cases, and deaths doubled during the study period. The age-standardised incidence rate of ischaemic stroke and haemorrhagic stroke in 2017 was 21.72 and 20.72 per 100 000 population, respectively. CONCLUSIONS The burden of stroke is increasing in Kurdistan Province. Since health services in Iran are based on treatment, steps are needed to revise the current treatment services for stroke and to improve the quality of services. Policy-makers and managers of the health system need to plan to reduce the known risk factors for stroke in the community. In addition to preventive interventions, efficient and up-to-date interventions are recommended for the rapid diagnosis and treatment of stroke patients in hospitals. Along with therapeutic interventions, preventive interventions can help reduce the stroke burden.

Abstract
The relationship between heavy metal exposure and risk of osteopenia or osteoporosis has biological plausibility, yet it remains inconclusive; therefore, we conducted a systematic review and meta-analysis to evaluate the associations between exposure to heavy metals (i.e., cadmium, lead, and mercury) and the risk of osteopenia or osteoporosis. Databases of MEDLINE, Embase, Scopus, and Web of Science were searched through November 2019, to identify studies that evaluated the relationship between exposure to cadmium, lead, and mercury and risk of osteopenia or osteoporosis in adults. Fourteen eligible studies were included. Effect sizes expressed as pooled odds ratios (OR) and 95% confidence intervals (CI) were estimated using weighted random-effect models. Exposure to cadmium (OR = 1.35; 95% CI: 1.17 to 1.56; P ≤ 0.001) and lead (OR = 1.15; 95% CI: 1.00 to 1.32; P = 0.05) was associated with an increased risk of osteopenia or osteoporosis, unlike mercury. Subgroup analyses showed cadmium exposure increased the risk of osteopenia or osteoporosis in older (> 65 yrs.; OR = 1.43; 95%CI: 1.08 to 1.88, P = 0.01) compared with younger (18-65 yrs.; OR = 1.24; 95% CI: 1.02 to 1.52, P = 0.03) adults. Also, lead exposure increased the risk in men (OR = 1.55; 95% CI: 1.15 to 2.09, P = 0.007) unlike in women. By contrast to urinary levels, blood (OR = 1.26; 95% CI: 1.08 to 1.47, P = 0.003) and dietary (OR = 1.46; 95% CI: 1.28 to 1.67, P < 0.001) levels of cadmium were associated with an increased risk of osteopenia or osteoporosis. Exposure to cadmium and lead may be associated with an increased risk of osteopenia or osteoporosis, although high heterogeneity was detected.

Abstract
INTRODUCTION Dental caries and inequalities in dental health are major public health concerns. AIM To report variation in dental caries experience across deprivation quintiles and the magnitude of inequalities between countries. DESIGN Secondary analyses of cross-sectional data from the 2013 Child Dental Health Survey (CDHS) in England, Wales, and Northern Ireland. MATERIALS AND METHODS Distribution of dental caries across deprivation quintiles were estimated using as proportions and means. The magnitude of inequalities was calculated using the Relative Index of Inequality (RII). MAIN OUTCOMES Dental caries experience as indicated by the prevalence (%dmft/DMFT>0) and severity (dmft/DMFT) of 'obvious' and 'clinical' decay experience in both primary and permanent dentitions. RESULTS Children from more deprived quintiles showed higher prevalence and severity of dental caries. RIIs for dental caries were greater in England than Wales or Northern Ireland, indicating greater relative inequalities despite lower average dental caries experience. The prevalence and severity of dental caries among the most deprived children in England were 1.7 to 3.7 times greater than those of the least deprived. CONCLUSION There is a deprivation gradient in child dental caries in all three countries, with England showing the greatest inequalities.

Abstract
In this study, a series of benzimidazole-1,2,3-triazole hybrids 8a-n as new α-glucosidase inhibitors were designed and synthesized. In vitro α-glucosidase inhibition activity results indicated that all the synthesized compounds (IC50 values ranging from 25.2 ± 0.9 to 176.5 ± 6.7 μM) exhibited more inhibitory activity in comparison to standard drug acarbose (IC50 = 750.0 ± 12.5 μM). Enzyme kinetic study on the most potent compound 8c revealed that this compound was a competitive inhibitor into α-glucosidase. Moreover, the docking study was performed in order to evaluation of interaction modes of the synthesized compounds in the active site of α-glucosidase and to explain structure-activity relationships of the most potent compounds and their corresponding analogs.

Abstract
We use metal nanostructures (nanoplasmonics) excited with dual frequency lasers to generate and detect high-frequency (>10 GHz) sound wave resonances in water. The difference frequency between the two lasers causes beating in the intensity, which results in a drop in the transmission through the nanostructure when an acoustic resonance is excited. By observing the resonance frequency shifts with changing nanostructure size, the transition from slow to fast sound in water is inferred, which has been measured by inelastic scattering methods in the past. The observed behavior shows remarkable similarities to finite element simulations using a simple Debye model for sound velocity (without fitting parameters).

Abstract
MicroRNAs (miRNAs) are a broad class of non-coding RNAs nearly 21 nucleotides length, which play crucial functions in post-transcriptional gene regulation. These molecules are associated with many developmental and cellular processes in eukaryotic organisms. Current investigation has reported major factors contributing to miRNA biogenesis and has constituted basic principles of miRNA function. More recently, it was confirmed that various miRNAs are clearly implicated in human malignancies, such as lung, breast, ovarian, bladder, colon cancer and other kinds of carcinoma. In addition, dysregulation in the miRNA machinery elements such as Dicer, Drosha, DGCR8, Argonaut, and TRBP could be involved in the progress of many tumor types. The purpose of the current review was to compile growing information besides how miRNA biogenesis and gene silencing are modified to develop cancer.

Abstract
BACKGROUND To assess the relationship between serum 25(OH) vitamin D levels and metabolic parameters together with androgenic hormone levels in women with polycystic ovary syndrome (PCOS). METHODS This is a single-centre study from the Endocrinology Institute at Firouzgar Hospital in Iran. Seventy-three women aged 15-45 years were recruited from May 2013 to December 2013. Serum 25(OH) vitamin D level, other laboratory biomarkers and anthropometric indexes were measured. Data were analysed with statistical software SPSS version 16.0 for windows and we used specific analytical tests to assess data. RESULTS Serum 25(OH) vitamin D levels were < 20 ng/ml in 64 patients (79%). Nine patients (12.3%) were diagnosed with metabolic syndrome. A significant difference was found between the women with and without severe vitamin D deficiency with regard to waist circumference, fasting insulin level and HOMA-IR, and abnormal systolic and diastolic blood pressures. The serum 25(OH) vitamin D levels had a reverse but weak correlation with systolic and diastolic blood pressures. CONCLUSION This study showed an association between serum 25(OH) vitamin D levels and some metabolic parameters; however, there was no significant linear correlation between serum 25(OH) vitamin D levels and metabolic variables, except for systolic and diastolic blood pressure.

Abstract
UNLABELLED The researchers sought to test the possible link between resting metabolic rate and bone mineral density through four adipokines. Participants with lower resting metabolic rate (RMR) per kilogram demonstrated higher total bone mineral density (BMD), total T-score, and total Z-score. Omentin-1 had a mediatory effect on the relationship between RMR/kg of body weight and bone parameters. INTRODUCTION The previous results of studies regarding the links between obesity and bone health are controversial. For this reason, the researchers sought to test the possible link between RMR and BMD through the following four adipokines: vaspin, retinol binding protein 4, angiopoietin-like 6 (ANGPL6), and omentin-1. METHODS We enrolled 312 obese Iranian women (30 ≤ body mass index <40) in this cross-sectional study. In order to examine the association of serum adipokine levels with RMR and BMD, the participants were grouped based on RMR per body weight. Body composition, dietary intake, bone mineral density, and resting metabolic rate were assessed in all participants. Serum adipokine levels were quantified by the enzyme-linked immunosorbent assay (ELISA) method. RESULTS Low levels of RMR/kg were strongly associated with higher weight, body mass index, fat mass, and visceral fat levels. In fact, participants with an RMR/kg of body weight <20 kcal/24 h/kg were more obese (p < 0.05). Another noteworthy finding was that participants with lower RMR/kg demonstrated higher total BMD, total T-score, and total Z-score. Our results showed that omentin-1 had a mediatory effect on the relationship between RMR per kilogram of body weight and bone parameters (p < 0.05). Nevertheless, other adipokines such as vaspin, retinol-binding protein 4 (RBP4), and ANGPL6 did not affect the relationship between RMR and BMD (p > 0.05). CONCLUSIONS The inhibitory effect of omentin-1 on TNF-alpha seems to be able to reduce the amount of circulating leptin as adipokine, affecting energy expenditure and improving bone loss induced by estrogen deficiency and controlled effect of RMR on BMD.

Abstract
This study aimed to examine the efficacy and maintenance of short-term (one-session) gated audiovisual speech training for improving auditory sentence identification in noise in experienced elderly hearing-aid users. Twenty-five hearing aid users (16 men and 9 women), with an average age of 70.8 years, were randomly divided into an experimental (audiovisual training, n = 14) and a control (auditory training, n = 11) group. Participants underwent gated speech identification tasks comprising Swedish consonants and words presented at 65 dB sound pressure level with a 0 dB signal-to-noise ratio (steady-state broadband noise), in audiovisual or auditory-only training conditions. The Hearing-in-Noise Test was employed to measure participants’ auditory sentence identification in noise before the training (pre-test), promptly after training (post-test), and 1 month after training (one-month follow-up). The results showed that audiovisual training improved auditory sentence identification in noise promptly after the training (post-test vs. pre-test scores); furthermore, this improvement was maintained 1 month after the training (one-month follow-up vs. pre-test scores). Such improvement was not observed in the control group, neither promptly after the training nor at the one-month follow-up. However, no significant between-groups difference nor an interaction between groups and session was observed. Conclusion: Audiovisual training may be considered in aural rehabilitation of hearing aid users to improve listening capabilities in noisy conditions. However, the lack of a significant between-groups effect (audiovisual vs. auditory) or an interaction between group and session calls for further research.

Abstract
The present study compared elderly hearing aid (EHA) users (n = 20) with elderly normal-hearing (ENH) listeners (n = 20) in terms of isolation points (IPs, the shortest time required for correct identification of a speech stimulus) and accuracy of audiovisual gated speech stimuli (consonants, words, and final words in highly and less predictable sentences) presented in silence. In addition, we compared the IPs of audiovisual speech stimuli from the present study with auditory ones extracted from a previous study, to determine the impact of the addition of visual cues. Both participant groups achieved ceiling levels in terms of accuracy in the audiovisual identification of gated speech stimuli; however, the EHA group needed longer IPs for the audiovisual identification of consonants and words. The benefit of adding visual cues to auditory speech stimuli was more evident in the EHA group, as audiovisual presentation significantly shortened the IPs for consonants, words, and final words in less predictable sentences; in the ENH group, audiovisual presentation only shortened the IPs for consonants and words. In conclusion, although the audiovisual benefit was greater for EHA group, this group had inferior performance compared with the ENH group in terms of IPs when supportive semantic context was lacking. Consequently, EHA users needed the initial part of the audiovisual speech signal to be longer than did their counterparts with normal hearing to reach the same level of accuracy in the absence of a semantic context.

Abstract
OBJECTIVE Stress hyperglycemia is a transient increase in blood glucose during an acute physiological stress in the absence of diabetes. Stress hyperglycemia can be occurred in certain clinical conditions such as trauma, burns, sepsis and strokes in adults. In this study we aimed to evaluate the incidence of stress hyperglycemia among patients admitted to the Firouzgar hospital. METHOD In this analytical cross sectional study, all patients who referred to emergency department of Firouzgar hospital due to one of the causes of trauma, myocardial infarction (MI), subarachnoid hemorrhage (SAH), head trauma, sepsis, CVA, and abdominal surgery and had stress hyperglycemia during 2012-2014 were evaluated. Blood glucose test including random blood sugar (BS) and glycosylated hemoglobin (HbA1C) was performed for patients at admission. Patients with BS>180 mgmg/dl and no previous history of diabetes were enrolled in this study. Patients were referred to endocrinology clinic after 3 months of the first test and were re-evaluated for diabetes mellitus. Fasting Blood Sugar (FBS), HbA1C and 2 h post glucose load test blood sugar were measured. Diabetes was confirmed if FBS was above 126 mg/dl or 2 h post glucose load BS was over 200 mg/dl. RESULT A total of 98 (67 males & 31 women) patients enrolled in the study. No significant statistical relation found between mean of HBA1C at 3 months after admission and the background event (P=0.138). No statistical relation found between BMI and developing diabetes (P=0.352). 26 and 8 percent of the participants developed diabetes, and 25.8% were in pre-diabetic state. There was a statistical relation between gender and developing diabetes (P=0.027) and men developed diabetes more than women. Based on logistic regression the Odds Ratio (OR) was 1.017. CONCLUSION Our study demonstrates a significant relationship between stress hyperglycemia and development of diabetes. Stress hyperglycemia could be a predicting factor of development of diabetes.

Abstract
OBJECTIVES A curvature leads to asymmetrical removal of root dentine, which results in an increase in the incidence of canal transportation. The aim of this study was to evaluate the effect of master apical file (MAF) size on the apical transportation (AT) of teeth with severe canal curvatures. METHODS Thirty-six mesial roots of human mandibular first molars were included. Inclusion criteria consisted of mature roots with closed apices, absence of carious lesions and resorptions, and root canal curvatures (CC) of 45 degrees < CC < 60 degrees. The root canals were prepared using a crown-down pressureless technique. The samples were equally divided into groups A, B, and C based on MAF size: group A: MAF size equivalent to #20; group B: MAF size equivalent to #25, and group C: MAF size equivalent to #30. Cone beam computed tomography was used to evaluate the AT. RESULTS There were no statistically significant differences in the AT between the canals with different curvature angles up to MAF size #30 (P = 0.55). CONCLUSION Using flexible hand files for canal preparation, an increase in MAF size up to #30 does not significantly influence AT in severely curved canals.
