Abstract
PURPOSE To investigate how a quality improvement program (BRIDGE), designed to promote coordination and continuity in rehabilitation services, was delivered and perceived by providers in routine practice for patients with rheumatic and musculoskeletal diseases. METHODS A convergent mixed methods approach was nested within a stepped-wedge, randomized controlled trial. The intervention program was developed to bridge gaps between secondary and primary healthcare, comprising the following elements: motivational interviewing; patient-specific goal setting; written rehabilitation-plans; personalized feedback on progress; and tailored follow-up. Data from health professionals who delivered the program were collected and analyzed separately, using two questionnaires and three focus groups. Results were integrated during the overall interpretation and discussion. RESULTS The program delivery depended on the providers' skills and competence, as well as on contextual factors in their teams and institutions. Suggested possibilities for improvements included follow-up with sufficient support from next of kin and external services, and the practicing of action and coping plans, standardized outcome measures, and feedback on progress. CONCLUSIONS Leaders and clinicians should discuss efforts to ensure confident and qualified rehabilitation delivery at the levels of individual providers, teams, and institutions, and pay equal attention to each component in the process from admission to follow-up.

Abstract
The effect of Crocus sativus on several disorders has been discussed or even confirmed, but the efficacy of this herb on the female reproductive system has not been well presented. In this regard, this systematic review comprehensively discussed the efficacy of C. sativus and its main phytochemical compounds on the female reproductive system and its disorders for the first time. In this systematic review, scientific databases, including PubMed, Web of Sciences, Google Scholar, Scopus, and Scientific Information Database, were explored profoundly. In vivo, in vitro, and human studies published until the end of July 2023, which had investigated the pharmacological properties of C. sativus, crocin, crocetin, safranal, or picrocrocin on the female reproductive system, were selected. A total of 50 studies conducted on the effect of C. sativus on the female reproductive system were acquired. These studies confirmed the efficacy of C. sativus or its main phytochemical ingredients in several aspects of the female reproductive system, including regulation of sex hormones, folliculogenesis, ovulation, and protection of the ovary and uterus against several oxidative stress. Several retrieved studies indicated that this herb also can alleviate the symptoms of patients suffering from dysmenorrhea, premenstrual syndrome, menopause, polycystic ovary disease (PCOD), and sexual dysfunction. Furthermore, it is a promising candidate for future studies or even trials regarding ovarian and cervical cancers. This review concluded that C. sativus can improve the symptoms of several female reproductive system disorders, which is particularly due to the presence of phytochemical ingredients, such as crocin, crocetin, and safranal.

Abstract
PURPOSE To explore what patients with rheumatic and musculoskeletal diseases (RMDs) need and receive of follow-up care after specialized rehabilitation, and whether received follow-up is associated with health outcomes after 1 year. Further, to compare these findings with patients' experiences to improve the understanding of how follow-up takes place. METHODS In a mixed methods study, patients received a rehabilitation programme designed to improve the continuity in rehabilitation across care levels. A total of 168 patients completed questionnaires, of which 21 were also interviewed. RESULTS At discharge, most patients reported needs for follow-up. These needs were largely met within 1 year, mainly resulting from patients' initiatives to re-connect with previous contacts. The degree of received follow-up was not associated with goal attainment, quality of life, or physical function. Factors related to providers (competence, communication skills), context (delays, limited access to care), and patients (motivation, life situation, preferences) seemed to be decisive for the progress of the rehabilitation process over time. CONCLUSIONS The results provide evidence that access to follow-up care is crucial to patients with RMDs. However, it also highlights several factors that may influence its impact. These results can be used to optimise design and implementation of future follow-up interventions.

Abstract
Oligochaetes are the most abundant benthic taxa in aquatic ecosystems that play an important role in food webs. The present study aims to assess the diversity and origin of Eiseniella tetraedra as a non-native species in the Lar National Park of Iran and also its response to current and future climate change. We obtained the specimen from rivers and sequenced the mitochondrial gene Cytochrome Oxidase subunit I (COI) and combined them with 117 sequences from the Jajroud and Karaj rivers in Iran and native regions from GenBank (NCBI). We also ran Species Distribution Modelings (SDMs) using an ensemble model approach that was estimated according to two shared socio-economic pathways (SSPs): 126 and 585 of the MRI-ESM2 based on CMIP6. According to the results, all the samples examined in the current study originated from Spanish rivers, and no unique haplotype was found in the Lar National Park. Moreover, the results also show high haplotype diversity that can positively affect the success of this non-native species in different freshwater. Also, the results of SDMs depict that climate change would remarkably affect the distribution of E. tetraedra and it verifies the invasion power of E. tetraedra in Iran's freshwater ecosystems over time.

Abstract
Introduction Ulcerative colitis (UC) is a chronic recurrent inflammatory disease of the large intestine and rectum. The disease is characterized by oxidative stress and severe inflammation. Research has shown the anti-oxidative and anti-inflammatory effects induced by consuming the Acacia arabia and Ocimum basilicum. The present study aimed to evaluate the effect of treatment with O. basilicum together with A. arabica on healing, inflammation, and oxidative stress in the course of experimental colitis in rats. Methods A total number of 50 male rats were selected and randomly assigned to five groups of 10 rats each. Colitis was induced in rats by enemas with a 4 % acetic acid solution. Four days after the colitis induction, the rats were orally treated for the next 4 days with saline or a combination of A. arabica and O. basilicum (1000 mg/kg) or sulfasalazine (100 mg/kg). Results Acetic acid-induced colitis increased the colon's macroscopic and histopathological damage scores; increased colon levels of MDA (Malondialdehyde), MPO (Myeloperoxidase), TNF-α (Tissue necrosis factor α), IL6 (Interleukin 6), and IL17 (Interleukin 17); and decreased SOD (Superoxide Dismutase), GPx (Glutathione Peroxidase), and IL10 (Interleukin 10) levels in the treated rats compared with the control group (P < 0.001). Overall, a combination of A. arabica and O. basilicum reduced macroscopic and histopathological damage scores (P < 0.01) of the colon, and MDA, MPO, TNF-α, IL6 (P < 0.001), and IL17 (P < 0.01) levels of the colon. Furthermore, it increased SOD, GPx, and IL10 levels compared to the colitis group (P < 0.01). Conclusion A. arabica and O. basilicum have improving effects on UC by reducing inflammation and oxidative stress.

Abstract
Purpose This study aims to create a science map, provide structural analysis, investigate evolution, and identify new trends in Helicobacter pylori (H. pylori) research articles. Methods All Helicobacter publications were gathered from the Web of Science (WoS) database from August 2010 to 2021. The data were required for bibliometric analysis. The bibliometric analysis was performed with Bibliometrix R Tool. Bibliometric data were analyzed using the Bibliometrix Biblioshiny R-package software. Results A total of 17,413 articles were reviewed and analyzed, with descriptive characteristics of the H. pylori literature included. In journals, 21,102 keywords plus and 20,490 author keywords were reported. These articles were also written by 56,106 different authors, with 262 being single-author articles. Most authors' abstracts, titles, and keywords included "Helicobacter-pylori." Since 2010, the total number of H. pylori-related publications has been decreasing. Gut, PLOS ONE, and Gastroenterology are the most influential H. pylori journals, according to source impact. China, the United States, and Japan are the countries with most affiliations and subjects. In addition, Seoul National University has published the most articles about H. pylori. According to the cloud word plot, the authors' most frequently used keywords are gastric cancer (GC), H. pylori, gastritis, eradication, and inflammation. "Helicobacter pylori" and "infection" have the steepest slopes in terms of the upward trend of words used in articles from 2010 to 2021. Subjects such as GC, intestinal metaplasia, epidemiology, peptic ulcer, eradication, and clarithromycin are included in the diagram's motor theme section, according to strategic diagrams. According to the thematic evolution map, topics such as Helicobacter pylori infection, B-cell lymphoma, CagA, Helicobacter pylori, and infection were largely discussed between 2010 and 2015. From 2016 to 2021, the top topics covered included Helicobacter pylori, H. pylori infection, and infection.

Abstract
OBJECTIVE To compare the effectiveness of a structured goal-setting and tailored follow-up rehabilitation intervention with existing rehabilitation in patients with rheumatic and musculoskeletal diseases. DESIGN A pragmatic stepped-wedge cluster randomized trial. SETTING Eight rehabilitation centers in secondary healthcare, Norway. PARTICIPANTS A total of 374 adults with rheumatic and musculoskeletal diseases were included in either the experimental (168) or the control group (206). INTERVENTIONS A new rehabilitation intervention which comprised structured goal setting, action planning, motivational interviewing, digital self-monitoring of goal progress, and individual follow-up support after discharge according to patients' needs and available resources in primary healthcare (the BRIDGE-intervention), was compared to usual care. MAIN MEASURES Patient-reported outcomes were collected electronically on admission and discharge from rehabilitation, and after 2, 7, and 12 months. The primary outcome was patients' goal attainment measured by the Patient Specific Functional Scale (0-10, 10 best) at 7 months. Secondary outcome measures included physical function (30-s Sit-To-Stand test), health-related quality of life (EQ-5D-5L-index), and self-assessed health (EQ-VAS). The main statistical analyses were performed on an intention-to-treat basis using linear mixed models. RESULTS No significant treatment effects of the BRIDGE-intervention were found for either primary (Patient Specific Functional Scale mean difference 0.1 [95% CI: -0.5, 0.8], p = 0.70), or secondary outcomes 7 months after rehabilitation. CONCLUSION The BRIDGE-intervention was not shown to be more effective than existing rehabilitation for patients with rheumatic and musculoskeletal diseases. There is still a need for more knowledge about factors that can improve the quality, continuity, and long-term health effects of rehabilitation for this patient group.

Abstract
Mountains play a key role in forming biodiversity by acting both as barriers to gene flow among populations and as corridors for the migration of populations adapted to the conditions prevailing at high elevations. The Anatolian and the Zagros Mountains are located in the Alpine-Himalayan belt. The formation of these mountains has influenced the distribution and isolation of the animal population since the late Cenozoic. Apathya is a genus of lacertid lizards distributed along these mountains with two species, i.e., Apathya cappadocica and Apathya yassujica. The taxonomy status of lineages within the genus is complicated. In this study, we tried to collect extensive samples from throughout the distribution range, especially within the Zagros Mountains. Also, we used five genetic markers, two mitochondrial (COI and Cyt b) and three nuclear (C-mos, NKTR, and MCIR), to resolve the phylogenetic relationships within the genus and explain several possible scenarios that shaped multiple genetic structures. The combination of results in the current study indicated eight well-support monophyletic lineages that separated to two main groups; group 1 including A. c. cappadocica, A. c. muhtari and A. c. wolteri, group 2 contains four regional clades Turkey, Urmia, Baneh and Ilam, and finally a single clade belonging to the species A. yassujica. In contrast to previous studies, Apathya cappadocica urmiana was divided into four clades and three clades were recognized within Iranian boundaries. The clades have dispersed from Anatolia to adjacent regions in the south of Anatolia and the western Zagros Mountains. According to the evidence generated in this study this clade is paraphyletic. Based on our assumption, orogeny activities and also climate fluctuations in Middle Miocene and Pleistocene have influenced to formation of lineages. In this study we revisit the taxonomy of the genus and demonstrate that the species diversity was substantially underestimated. Our findings suggest that each of the eight clades corresponding to subspecies and distinct geographic regions deserve to be promoted to species level.

Abstract
INTRODUCTION Functional Dyspepsia (FD) is one of the most frequent gastrointestinal disorders with a high burden. Although FD is a heterogeneous disorder without any standard therapy (treatment/treatment - repetition), there is a wide history of using herbal remedies for its treatment. Two of these herbal remedies quoted in various Persian medicine resources are Celery and Ajwain. Their effects have been investigated in recent clinical trials in FD patients. We aimed to compare the effect of Celery and Ajwain to that of Domperidone in patients with postprandial distress syndrome. METHODS This is a randomized double-blind active-control clinical trial, conducted at Kerman, Iran in 2020. Participants of this study were 100 patients suffering from FD (postprandial distress syndrome subtype). The intervention group received 1 g of the combination of Celery and Ajwain (Apium graveolens L. and Trachyspermum copticum (L.) Link) while the control group received 30 mg of Domperidone per day for 4 consecutive weeks. Primary outcomes were symptoms severity and frequency, and secondary outcomes were quality of life (QoL) and safety. All outcomes were assessed at the end of the trial, and also 4 weeks after the trial was finished. RESULTS No significant differences in symptoms frequency were found between groups. However, differences in symptoms severity were found at the end of the follow-up (week 8) (P= 0.001). The intra-group analysis showed a significant decrease in the symptoms severity and frequency at the end of week 4 in both groups (P<0.001). QoL in the intervention group was higher compared to the control group at the end of the study (P<0.001) and at the point of the follow-up (week 8; P<0.001). No serious adverse events occurred in either group. CONCLUSION The herbal mixture of Celery and Ajwain could be considered a safe and effective remedy, decreasing the severity of symptoms and increasing QoL in patients with postprandial distress syndrome. It is further suggested to confirm these findings in high-quality multi-center clinical trials.

Abstract
Diabetic peripheral neuropathy is one of the most common causes of disability in diabetic patients. Applying a method to achieve the highest therapeutic effect in patients is desirable. Therefore, this study aimed to evaluate the impact of leech therapy on diabetic neuropathy of lower limbs in comparison to gabapentin as a standard method. This randomized controlled parallel-group clinical trial was conducted among 40 patients with type II diabetes who were diagnosed with lower limb diabetic neuropathy and referred to specialized outpatient clinics in Babol, Mazandaran province, Iran from 23 September 2020 to 17 March 2021. The patients were randomly divided into two groups. One group was treated with leech therapy and the other group was treated with gabapentin as the standard method. The severity of neuropathy was assessed every 15 days until the 45th day. The Visual Analog Scale (VAS), Neuropathy Symptom Score (NSS), Neuropathy Disability Score (NDS), and Nerve Conduction Velocity (NCV), and Electromyography (EMG) were used for assessing the study outcomes. The repeated measure and Friedman tests were used by SPSS.V.23. The results of our study indicated that pain (P value:0.03), numbness (P value˂0.0001), and paranesthesia (P value:0.01) significantly reduced in patients undergoing leech therapy versus patients taking gabapentin on the 45th day. The total NSS (P value˂0.0001) and total NDS (P value˂0.0001) improved significantly for patients with leech therapy over 45 days compared to the patients with gabapentin. The results of our study showed that using leech therapy for patients with diabetic neuropathy was more effective in improving clinical symptoms and the functions of lower limb muscles and nerves in comparison to gabapentin. The severity and symptoms of neuropathy greatly improved for the patients treated with leech therapy versus patients taking gabapentin.

Abstract
Placental extract (PE) and exosomes from pregnant mice appear to have immunomodulatory and neuroprotective effects. In this study, we assessed the potential therapeutic effects of PE and exosomes obtained from pregnant mice in experimental autoimmune encephalomyelitis (EAE) mouse models. C57BL/6 mice, 8 to 12 weeks of age, were prepared and administered PE, exosomes, and glatiramer acetate (GA), as an FDA-approved treatment for multiple sclerosis (MS), after EAE induction. Thereafter, the therapeutic effects of treatment were evaluated by measuring the clinical courses of the mice as well as determining the number of regulatory T (Treg) cells using flow cytometry, cytokine levels, and microRNA-326 expression via real-time PCR. GA, PE, and exosomes reduced clinical severity, the extent of spinal cord demyelination, and the infiltration of inflammatory cells into the spinal cord. The frequency of CD4+CD25+FoxP3+ Treg cells increased after treatment of EAE mice with GA, PE, and exosomes. The mRNA expression of the inflammatory cytokines (interleukin-17 and interferon-gamma), as well as miR-326 expression, decreased significantly in the EAE mice after treatment with GA and exosomes. PE and exosomes from pregnant mice are involved in the modulation of Treg/Th17 balance and provide a therapeutic approach for MS. Further clinical studies will hopefully confirm the safety and efficacy of such treatments in MS patients.

Abstract
Background and purpose Irritable bowel syndrome (IBS) is a disease that shows its impacts on many populations worldwide. It is known as a functional disorder of the gastrointestinal tract followed by diarrhea and fecal inconsistency. Due to the lack of treatment in the allopathic medicine system for IBS, people in the western world use different herbs as alternative medicine. In the present study, we evaluated the dried extract of Dracocephalum kotschyi against IBS. Experimental approach In a randomized, double-blinded, placebo-controlled clinical trial, 76 diarrhea-predominant IBS patients were randomly assigned to two equal groups: the control group (given the placebo capsule containing 250 mg of dibasic calcium phosphate) and the treatment groups (given the capsule containing 75 mg of the dry extract of D. kotschyi and 175 mg of dibasic calcium phosphate as filler). The study was conducted based on Rome III criteria. We studied symptoms included in Rome III criteria and divided the study into the duration of drug administration and four weeks after drug administration. These groups were compared with those of the control group. Findings/Results Significant improvements were found in the quality of life, temperament, and IBS symptoms throughout the treatment duration. Quality of life, temperature, and IBS symptoms were slightly decreased in the treatment group 4 weeks after stopping the treatment. While concluding the study, we found D. kotschyi effective against IBS. Conclusion and implications Whole extract of D. kotschyi modulated symptoms of IBS patients and improved their quality of life.

Abstract
Multiple sclerosis (MS) is a chronic autoimmune disorder of central nervous system which is increasing worldwide. Although immunosuppressive agents are used for the treatment of MS disease, nevertheless the lack of non-toxic and efficient therapeutic method is perceptible. Hence, this study aims to evaluate the effect of Contactin-associated protein (Caspr) antibody-, poly ethylene glycol (PEG)- and exosome combined gold nanoparticles (GNPs) in comparison to Glatiramer acetate as a selective treatment of MS disease in the experimental autoimmune encephalomyelitis (EAE) mouse model. EAE was induced in female C57BL/6 mice and 25-day treatment with anti-Caspr-, PEG- and exosome combined GNPs was evaluated. Histopathological examination of spinal cord, regulatory T cells as well as inflammatory pathway including IFN-ɣ and IL-17 and mir-326 were investigated. The results showed the severity of MS symptoms was significantly decreased in all treated groups. Histological examination of the spinal cord indicated the reduced demyelination and immune cell infiltration. Besides, regulatory T cells were significantly increased following all treatments. Remarkably, the cytokine levels of IFN-ɣ and IL-17 as well as mir-326 is altered in treated groups. Taken together, the obtained findings demonstrate that the administration of anti-Caspr-, PEG- and exosome combined GNPs can be considered a potential treatment in MS disease.

Abstract
COVID-19 spread rapidly around the world from the end of 2019. Hot footbath is a simple ancient technique, which has been used to alleviate many disorders. We aimed to investigate the effect of hot footbath in hospitalized COVID-19 patients. This open-label randomized controlled trial was conducted in Iran with allocation ratio of 1:1, with final sample size of 35 patients in each group. The intervention group received hot footbath (immersion of feet into the hot water at 42 °C, 10 cm above the ankles for 20 minutes, and then kept warm for 5 minutes) once a day for a week, in addition to the conventional therapy. The control group received only the conventional therapy; the primary outcomes evaluated were fever, respiratory rate, cough, fatigue, and myalgia; whereas admission rate, ICU admission, and mortality were assessed as the secondary outcomes. Except for cough intensity, cough frequency and fatigue (p value < 0.05), no significant differences were observed between the two groups in the primary and secondary outcomes. No adverse events were reported. Hot footbath can be used as a non-invasive, highly acceptable, and complementary technique to alleviate COVID-19 patients without any needs to expensive or special equipment; nevertheless, further studies with larger sample sizes are needed so as to accurately evaluate the effectiveness of hot footbath on clinical symptoms of COVID-19.

Abstract
Background Aquaporins are channel proteins, form pores in the membrane of biological cells to facilitate the transcellular and transepithelial water movement. The role of Aquaporins in carcinogenesis has become an area of interest. In this study, we aimed to investigate the effects of adipose-derived mesenchymal stem cells secreted exosomes on the expression of aquaporin 5 and EGFR genes in the HCT-116 tumor cell line. Methods and results Surface antigenic profile of Ad-MSCs was evaluated using specific markers. Exosomes were purified from the Ad-MSc supernatant while the quality and the shape of isolated exosomes were assessed by western blot and transmission electron microscopy (TEM) respectively. HCT-116 cells were co-cultured with MSC-conditioned medium (MSC-CM) and/or with 100 μg/ml of MSC-derived exosomes for 48 h and. Real-time PCR was carried out to determine the expression of aquaporin5 and EGFR in HCT-116. Relative expression levels were calculated using the 2-ΔΔct method. Our result showed that AQP5 and EGFR mRNA levels were significantly reduced in CM and/or exosomes treated HCT116 compare to the control group (P-value < 0.05). Conclusion The current study showed that MSC derived exosomes could inhibit expression of two important molecules involved in tumor progression. Hence it seems MSCs-derived exosomes may hold a hopeful future as drug delivery vehicles which need the furtherer investigation.

Abstract
Background & aim Ulcerative colitis (UC) is a chronic recurrent inflammatory disease of the large intestine and rectum that oxidative stress and severe inflammation are the main features of this disease. Previous studies have shown that separate consumption of basil and gum arabic can reduce inflammation and oxidative stress. The aim of the study was evaluating the effect of treatment with basil seeds given together with gum arabic on healing, inflammation and oxidative stress in the course of experimental colitis in rats. Experimental procedure A total number of 50 male rats were used, randomly assigned to five groups of 10 rats each. Colitis was induced in rats by enemas with 4% solution od acetic acid. Four days after induction of colitis, rats were treated for next 4 days with saline or combination of basil seeds plus gum arabic (1 mg/kg) or sulfasalazine (100 mg/g) rectally. The experiment was terminated after last dose of treatment. Rats without induction of colitis were used as a sham group. Results Acetic acid-induced colitis increased the macroscopic and histopathological damage scores of the colon as well as colon levels of MDA(Malondialdehyde), MPO(Myeloperoxidase), TNFα(Tissue necrosis factor α), IL6 (Interleukin 6)and IL17(Interleukin 17) and decreased SOD(Superoxide Dismutase), GPx (Glutathione Peroxidase) and IL10 (Interleukin 10) levels compared with the control group(P < 0.001). Treatment with basil and gum arabic reduced macroscopic and histopathological damage scores (P < 0.01) of the colon, MDA, MPO, TNFα, IL6(P < 0.001) and IL17 (P < 0.01) levels of the colon and increased SOD, GPx and IL10 levels compared to the colitis group (P < 0.01). Conclusion Rectal administration of combination of basil seeds plus gum arabic after induction of colitis, exhibits antioxidant and anti-inflammatory effects, and accelerates the healing of the colon in experimental colitis evoked by acetic acid.

Abstract
The purpose of this research was to investigate the gene expression levels of inflammatory cytokines interferon (IFN)γ, tumor necrosis factor (TNF)α, interleukin (IL)1β, IL2, IL6, IL8, and IL17, and anti-inflammatory cytokines IL4, IL10, IFNα, and IFNβ, as well as relevant key transcription factors (TFs), including GATA3, PU1, NF-κB (nuclear factor kappa-light-chain-enhancer of activated B cells), IRF3 (interferon regulatory factor 3), BCL6 (B cell lymphoma 6 protein), FOXP3 (forkhead box P3), RORγt, and T-bet (T-box expressed in T cell) in Iranian patients with moderate and severe coronavirus disease 2019 (COVID-19). Fifty-six patients with COVID-19, and 25 healthy controls (HCs) age and sex matched were investigated. Based on the interim guidance of COVID-19 from the World Health Organization, the patients were classified into 33 moderate and 23 severe patients with COVID-19. The gene expression levels of cytokines and relevant TFs were quantified in peripheral blood mononuclear cells by quantitative real-time polymerase chain reaction (qRT-PCR). The gene expression levels of TFs RoRγ (RAR-related orphan nuclear receptor γ), NF-κB, and T-bet were significantly higher in patients with COVID-19 compared with HCs. Furthermore, the gene expression levels of cytokines, including IL2, IFNγ, IL6, TNFα, IL1β, IL8, and IL17, were significantly higher in patients with COVID-19 than HCs. However, there was a significant increase for IL6, TNFα, and IL17 in severe compared with moderate patients with COVID-19. Finally, The Spearman correlation analysis revealed a significantly positive correlation for IL6 and TNFα, IL6 and IL2, IL6, IFNγ, and IL2 and IFNγ. These data suggest that expression of IL6, TNFα, and IL17 as well as the synergic effect of elevated values of IL2 and IFNγ should be considered in the treatment and management of patients with severe COVID-19.

Abstract
The human colon harbors a diverse array of microorganisms that play fundamental roles in colorectal cancer (CRC). Increasing evidence indicates that dysbiosis of the intestinal microbiome has been associated with the development of CRC. Interaction between host genetics, intestinal microbiota, and lifestyle is well-indicated in the influence, prevention, and treatment of CRC. Various microbiome compositions have reported anticancer and/or anti-inflammatory properties. The presence of our microbiota is integral to our development, but a change in its composition can often lead to adverse effects, increasing the propensity for serious diseases like cancers. Recently, molecular detection and metabolomic techniques have increased our knowledge of the role of microbiota in promoting tumorigenesis. Dietary interventions may be appropriate to regulate the growth of beneficial microbiota in the gut. Metagenomic approaches along with immunology and metabolomics will obvious a new path for the treatment of CRC. In this study, we summarized recent advances in understanding the mechanisms involved in microbiota-related colorectal carcinoma, based on evidence from immunotherapy studies.

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of coronavirus disease 2019 (COVID-19), is currently the major global health problem. Still, it continues to infect people globally and up to the end of February 2022, over 436 million confirmed cases of COVID-19, including 5.95 million deaths, were reported to the world health organization (WHO). No specific treatment is currently available for COVID-19, and the discovery of effective therapeutics requires understanding the effective immunologic and immunopathologic mechanisms behind this infection. Type-I interferons (IFN-Is), as the critical elements of the immediate immune response against viral infections, can inhibit the replication and spread of the viruses. However, the available evidence shows that the antiviral IFN-I response is impaired in patients with the severe form of COVID-19. Moreover, the administration of exogenous IFN-I in different phases of the disease can lead to various outcomes. Therefore, understanding the role of IFN-I molecules in COVID-19 development and its severity can provide valuable information for better management of this disease. This review summarizes the role of IFN-Is in the pathogenesis of COIVD-19 and discusses the importance of autoantibodies against this cytokine in the spreading of SARS-CoV-2 and control of the subsequent excessive inflammation.

Abstract
BackgroundThere is a well-known variability in the quality of rehabilitation provided to patients with rheumatic and musculoskeletal diseases (RMDs). Elements to be improved are a higher standardization of the core content, optimal patient participation in goal setting and continuation of the process in tailored follow-up. More knowledge is needed on critical features for successful delivery of improvement programs in rehabilitation.ObjectivesTo investigate how a team-based quality improvement program was implemented and how it influenced the quality in RMD rehabilitation.MethodsThis convergent mixed methods study is nested within a stepped-wedge, randomized controlled trial where providers at 8 rehabilitation-centers delivered traditional programs in the control phase (T1), and added the BRIDGE quality improvement program in the intervention phase (T2). The BRIDGE program addressed a dialog-based, multidisciplinary approach to support the patients’ self-management, comprising motivational interviewing, goal setting, plans for rehabilitation, feedback and monitoring of progress, and tailored follow up. Providers answered 19 structure indicators from a quality indicator (QI) set for RMD rehabilitation [1] at T1 and T2, and a program-fidelity checklist with 18 items at T2 (both scored 0-100%, 100=best). Qualitative data was collected in three focus groups (FG) with the BRIDGE providers, and analyzed using reflexive thematic analysis. Integration and discussion of findings from the different data sources are ongoing, in our research group.ResultsMedian summary pass rate for the structure QIs for all centers increased from 53 to 90% between T1 and T2. Program-fidelity was high, with a median summary score of 94% (range 6–100%), but lowest for program-components related to follow-up and communication with external services. Themes developed from the FG interviews reflected that variations in how the program was implemented related to features of the providers and institutions. More specific; the delivery of high-quality rehabilitation depended on the degree to which the providers trained their communication skills, used available tools to support their practice, and grounded their interventions in professional reasons. Critical organisational features at the institutions were dedicated time for team-work based on the patients’ plans for self-management, and sufficient attention to needs for involvement of next of kin or external services. Additionally, better program-implementation occurred if providers experienced an institutional culture for quality improvement, such as educational initiatives from the leaders.Preliminary integration of data is summarized in Figure 1. Congruent evidence in both quantitative and qualitative findings addressed the sustained needs for better quality in the area of follow-up across levels of care. However, the qualitative findings provided expanded insights on variability also in initial parts of the rehabilitation process. Presumably, these variations in delivery reported in interviews are important for the effectiveness of a quality improvement program, but difficult to capture in questionnaires.Figure 1.Complementary viewpoints on how the BRIDGE program was provided and how it influenced the quality of rehabilitation.ConclusionTo target specific strategies for quality improvement, we suggest a combined attention not only to recommended care reflected in quality indicators and measurable aspects of fidelity, but also to contextual factors, including the providers’ confidence and skills needed to provide a high-quality delivery of all components in a rehabilitation improvement program.References[1]Johansen et al.

Abstract
Rheumatoid arthritis (RA) is an autoimmune-related disorder characterized by chronic inflammation. Although the etiopathogenesis of RA still remains to be clarified, it is supposed that the breakdown of immune self-tolerance may contribute to the development of RA. Thus, restoring of immune tolerance at the site of inflammation is the ultimate goal of RA treatment. Regulatory T cells (Treg cells) are the main suppressive cells that maintain tolerance and inhibit immunity against auto-antigen. Of note, recent studies demonstrated the efficacy of adoptive transfer of Treg cells in the modulation of the unwanted immune response, which makes them an ideal candidate to maintain immune homeostasis and restore antigen-specific tolerance in the case of RA and other autoimmune diseases. This review intends to submit recent finding of Treg cells-based therapies in RA with a focus on strategies applied to improve the therapeutic value of Treg cells to restore immune tolerance.

Abstract
BACKGROUND Constipation is a common chronic bowel disorder with an incidence of more than 50% in the elderly population. Complementary and alternative medicine is a cost-effective and satisfactory treatment for constipation used widely by the elderly. OBJECTIVE This study evaluates the efficacy of an herbal formula made from Foeniculum vulgare Mill. and Rosa damascena for the treatment of constipation in an elderly population and consequent changes to their quality of life. DESIGN, SETTING, PARTICIPANTS AND INTERVENTION This double-blind randomized active controlled clinical trial, with parallel group allocation ratio of 1:1, was conducted in a referral clinic in Afzalipour Hospital, affiliated to Kerman University of Medical Sciences in Kerman, Southeastern Iran. Individuals over 60 years of age, diagnosed with functional constipation (based on the Rome IV criteria), were included in this study. Participants received a sachet of 10 g F. vulgare and R. damascena (herbal formula group) or polyethylene glycol 4000 (PEG 4000 group) with a glass of warm water two times a day for 4 weeks and were followed up for 4 additional weeks. MAIN OUTCOME MEASURES Constipation severity, stool consistency, and the quality of life were used as the primary outcomes. Drug side effects were used as a secondary outcome. The outcomes were assessed using the Constipation Assessment Scale, the Bristol Stool Form Scale, and the Patient Assessment of Constipation Quality of Life questionnaire. RESULTS A total of 25 participants in each group completed the four-week treatment cycle and the eight-week follow-up. At the end of the four-week treatment cycle, all clinical outcomes had significant improvements in both groups (P < 0.05). The analysis of constipation severity (P < 0.001), stool consistency (P < 0.001), and the quality of life (P < 0.001) showed significant improvements with fewer side effects (mild diarrhea) and a longer duration of symptom relief in the herbal formula group compared to the PEG 4000 group. CONCLUSION Although both interventions significantly improved the treatment outcomes, constipation severity, stool consistency and the quality of life were improved more effectively by the herbal formula than by PEG 4000; however, the mechanism of action is not yet understood. TRIAL REGISTRATION This trial was registered in the Iranian Registry of Clinical Trials (IRCTID: IRCT20200108046056N1).

Abstract
Background The quality of provided health care may be an important source of variation in rehabilitation outcomes, increasing the interest in associations between quality indicators (QIs) and improved patient outcomes. Therefore, we examined the associations between the quality of rehabilitation processes and subsequent clinical outcomes among patients with rheumatic and musculoskeletal diseases (RMDs). Methods In this multicentre prospective cohort study, adults with RMDs undergoing multidisciplinary rehabilitation at eight participating centres reported the quality of rehabilitation after 2 months and outcomes after 2, 7, and 12 months. We measured perceived quality of rehabilitation by 11 process indicators that cover the domains of initial assessments, patient participation and individual goal-setting, and individual follow-up and coordination across levels of health care. The patients responded “yes” or “no” to each indicator. Scores were calculated as pass rates (PRs) from 0 to 100% (best score). Clinical outcomes were goal attainment (Patient-Specific Functional Scale), physical function (30 s sit-to-stand test), and health-related quality of life (EuroQoL 5D-5L). Associations between patient-reported quality of care and each outcome measure at 7 months was analysed by linear mixed models. Results A total of 293 patients were enrolled in this study (mean age 52 years, 76% female). Primary diagnoses were inflammatory rheumatic disease (64%), fibromyalgia syndrome (18%), unspecific neck, shoulder, or low back pain (8%), connective tissue disease (6%), and osteoarthritis (4%). The overall median PR for the process indicators was 73% (range 11–100%). The PR was lowest (median 40%) for individual follow-up and coordination across levels of care. The mixed model analyses showed that higher PRs for the process indicators were not associated with improved goal attainment or improved physical function or improved health-related quality of life. Conclusions The quality of rehabilitation processes was not associated with important clinical outcomes. An implication of this is that measuring only the outcome dimension of quality may result in incomplete evaluation and monitoring of the quality of care, and we suggest using information from both the structure, process, and outcome dimensions to draw inferences about the quality, and plan future quality initiatives in the field of complex rehabilitation. Trial registration The study is part of the larger BRIDGE trial (ClinicalTrials.gov NCT03102814).

Abstract
Mechanisms underlying the systemic lupus erythematosus (SLE) have not yet been elucidated. In this study, we evaluated the balance of T cell subsets in BALB/c mice model of SLE induced; using Con A and polyamines as DNA immunogenicity modifiers. BALB/c mice were immunized subcutaneously with 50 µg extracted DNA from cells cultured in different conditions: splenocytes+ polyamines (group P), splenocytes+ Con A (group A), splenocytes+ polyamines+ Con A (group PA) and splenocytes only (control). Anti-double-stranded DNA -(ds-DNA) antibodies, proteinuria, and antinuclear autoantibodies were assessed by enzyme-linked immunosorbent assay, Bradford method, and immunofluorescence respectively. Transcription factors of different T helper subsets were examined by real-time polymerase chain reaction. The serum level of the anti-dsDNA antibody in group PA was higher than that in the other groups (p>0.05). Antinuclear antibody (ANA) titer increased in groups A and PA. Proteinuria level in group PA was significantly higher than that in the control group (p<0.001). Expression of Foxp3 was decreased in group A (p=0.001). Additionally, the ratios of T-bet/GATA3 and T-bet/Foxp3 were also increased in group A. (p>0.05). Our results revealed an increased ratio of Th1 to Th2 and decreased expression of Foxp3 in group A, but group PA manifested more obvious signs of the disease. These results suggest that other mechanisms rather than disturbance in T cells' balance may involve the development of disease symptoms.

Abstract
Purpose: Multiple sclerosis (MS) is a debilitating neuroinflammatory disorder of the central nervous system. It is believed to result from an impaired immune response against myelin components especially myelin oligodendrocyte glycoprotein (MOG). Some efforts have been made to bioconjugate the MOG peptides to tolerogenic particles like poly (lactic-co-glycolic acid) (PLGA) for treating animal models of autoimmune disorders. Accordingly, we aimed to elucidate the tolerogenic effects of MOG-PLGA particles on experimental autoimmune encephalomyelitis (EAE). Methods: PGLA nanoparticles were synthesized using water/oil/water procedure. Next, the MOG or ovalbumin (OVA) peptides covalently linked to the PLGA particles. These particles were then intravenously or subcutaneously administered to nine groups of C57BL/6 mice before and after EAE induction. The brain tissues were assessed for the infiltration of immune cells. The Tolerogenic effect of the vaccine was also assessed on the quantity of the Treg cells. Moreover, the amount of interferon-γ (IFN-γ), interleukin-10 (IL-10), and interleukin-17 levels produced by splenic lymphocytes were then quantified by ELISA. Results: Intravenous administration of PLGA500-MOG35-55 nanoparticles before EAE induction ameliorated EAE clinical scores as well as infiltration of immune cells into the brain. In the spleen, the treatment increased CD4+CD25+FoxP3+ Treg population and restored the homeostasis of IFN-γ, IL-10, and IL-17 (all P values <0.0001) among splenocytes. Conclusion: The conjugation of MOG peptides to the PLGA nanoparticles significantly recovered clinical symptoms and the autoimmune response of EAE. The MOG-PGLA particles are potentially valuable for further evaluations, hopefully progressing toward an optimal approach that can be translated to the clinic.

Abstract
BACKGROUND Quality of care is gaining increasing attention in research, clinical practice, and health care planning. Methods for quality assessment and monitoring, such as quality indicators (QIs), are needed to ensure health services in line with norms and recommendations. The aim of this study was to assess the responsiveness of a newly developed QI set for rehabiliation for people with rheumatic and musculoskeletal diseases (RMDs). METHODS We used two yes/no questionnaires to measure quality from both the provider and patient perspectives, scored in a range of 0-100% (best score, 100%). We collected QI data from a multicenter stepped-wedge cluster-randomized controlled trial (the BRIDGE trial) that compared traditional rehabilitation with a new BRIDGE program designed to improve quality and continuity in rehabilitation. Assessment of the responsiveness was performed as a pre-post evaluation: Providers at rehabilitation centers in Norway completed the center-reported QIs (n = 19 structure indicators) before (T1) and 6-8 weeks after (T2) adding the BRIDGE intervention. The patient-reported QIs comprised 14 process and outcomes indicators, measuring quality in health services from the patient perspective. Pre-intervention patient-reported data were collected from patients participating in the traditional program (T1), and post-intervention data were collected from patients participating in the BRIDGE program (T2). The patient groups were comparable. We used a construct approach, with a priori hypotheses regarding the expected direction and magnitude of PR changes between T1 and T2. For acceptable responsivess, at least 75% of the hypotheses needed to be confirmed. RESULTS All eight participating centers and 82% of the patients (293/357) completed the QI questionnaires. Responsiveness was acceptable, with 44 of 53 hypotheses (83%) confirmed for single indicators and 3 of 4 hypotheses (75%) confirmed for the sum scores. CONCLUSION We found this QI set for rehabilitation to be responsive when applied in rehabilitation services for adults with various RMD conditions. We recommend this QI set as a timely method for establishing quality-of-rehabilitation benchmarks, promoting important progress toward high-quality rehabilitation, and tracking trends over time. TRIAL REGISTRATION The study is part of the larger BRIDGE trial, registered at ClinicalTrials.gov (Identifier: NCT03102814).

Abstract
INTRODUCTION According to Rome IV, functional dyspepsia is diagnosed with the presence of dyspepsia in the absence of organic or metabolic causes. FD caused by several factors, such as impaired gastric accommodation and hypersensitivity to gastric distention. Several studies have reported the effectiveness of herbal medicine on FD. This article, thus, reviews Persian herbal medicine in FD. METHODS Electronic databases, including Pubmed, Scopus, Cochrane, Embase, Web of science and Ovid, were searched so as to find clinical articles related to dyspepsia and herbal medicine by July 2019. Our search strategies were traditional medicine, complementary and alternative medicine, herb, plant, and dyspepsia. We excluded all articles except Persian clinical trials. RESULTS We found 34 clinical trials with 15 herbs and 4 compound herbal remedies like Asparagus racemosus, Brassica oleracea, Cynara scolymus, Ocimum basilicum, Mentha longifolia, Mentha pulegium, Mentha piperata, Pimpinella anisum, Nigella sativa, Mastic gum, Curcuma longa, Pistatio Atlantica, Glycyrrhiza glabra, Solanum tuberosum and Zingiber officinale and compound remedies of Rosa damascene & Crocus sativus, Trachyspermum copticom & Apium graveolence, Carum carvi & Mentha pipperata, Gingiber officinalis & Cynara scolymus are effective in functional dyspepsia. CONCLUSION Many people use herbal and traditional remedies for the treatment of disorders such as gastrointestinal disorders, especially in Asian countries. Several studies reported the efficacy of herbal medicine in functional dyspepsia. Although their mechanisms are not fully understood, it seems they can modulate GI motility and improve symptoms of FD.

Abstract
Purpose: Promising advances have been made in mesenchymal stem cell transplantation to re-induce the immune tolerance in neuroinflammatory animal models and Multiple Sclerosis patients. The available evidence demonstrated that immunomodulatory effects of mesenchymal stem cell are particularly exerted through releasing exosomes to their environment. We therefore, aimed to comparatively assess the potential effect of mesenchymal stem cells and mesenchymal stem cells-derived exosomes on proliferation and function of the CD4+CD25− conventional T cells, isolated from relapsing-remitting Multiple Sclerosis patients. Methods: Mesenchymal stem cells were isolated from human umbilical cord tissues and used for exosome isolation via ultracentrifugation. Both mesenchymal stem cells and mesenchymal stem cells-derived exosomes were evaluated for their anti-inflammatory effects against the proliferation of T cells isolated from two groups of individuals in vitro, MS patients and healthy subjects. Cytokine production of conventional T cells (interferon-γ, interleukin-10, and interleukin-17) was also assessed, using flow cytometry for the patients and healthy individuals. Results: Here, evidence shows that MSCs and MSC-derived exosomes dampen proliferation and percentage of conventional T cells that produce IFN-γ (healthy control: p<0.001) and interleukin-17 (healthy control: p<0.001, MS patients: p<0.001), with a significant increase of IL-10 producing cells in the patients and healthy individuals. Surprisingly, MSC-derived exosomes demonstrated higher immune-modulating properties on conventional T cells responses, compared to MSCs. Conclusion: The current study, provides a novel approach of exocytosis on autoimmune therapy. In particular, Mesenchymal stem cell -derived exosomes, which are cell-derived biologics, could be considered as an alternative for Mesenchymal stem cells in treating multiple sclerosis.

Abstract
Multiple sclerosis (MS) is a central nervous system (CNS) degenerative disorder which is caused by a targeted autoimmune-mediated attack on myelin proteins. Previously, mesenchymal stem cells were considered as a novel and successful treatment of MS. One of the underlying mechanisms behind their immunomodulatory function is the release of extracellular vesicles, particularly exosomes. In this study, we aimed to evaluate the suppressive efficacy of MSCs and their exosomes on the proliferation of peripheral mononuclear blood cells (PBMC) in relapsing-remitting MS (RRMS) patients and healthy subjects. To do, mesenchymal stem cells were derived from human umbilical cord tissues and used for exosome isolation through ultracentrifugation. Suppressive function of MSCs and MSC-derived exosomes was examined in a coculture with CFSE-labelled PBMCs in vitro. PBMC proliferation of the patients and healthy individuals was measured using flow cytometry. We first demonstrated that proliferation of PBMCs decreased in the presence of MSCs and suppression was more efficient by MSC-derived exosomes, with a minimum alloreaction rate. However, suppression capacity of MSCs and their exosomes significantly decreased during extensive sub-culturing. The present study showed that MSC-derived exosomes as an effective cell-free therapy could prevent proliferation of PBMCs. However, further evaluations are need to move towards a functional approach that can be translated to the clinic.

Abstract
With the development of novel treatments for autoimmune disorders, it has become a popular research focus which mesenchymal stem cells (MSCs) have the capacity to counteract with autoimmune diseases progression. One of the underlying mechanisms behind their activities is the release of extracellular vesicles especially exosomes. MSC-derived exosomes are hypoimmunogenic nanocarriers which contain numerous immunoregulatory factors and similar to other exosomes, are able to pass through boundaries like the blood-brain barrier (BBB). Accumulating evidence provided by animal studies has demonstrated that MSC-derived exosomes, as a novel therapy, can re-induce self-tolerance, without subsequent complications reported for other treatments. Therefore, therapeutic applications of MSC-derived exosomes are contributing to core advances in the field of autoimmune diseases. Here, we briefly describe the biological characteristics of MSC-derived exosomes and review the experimentally verified outcomes for autoimmune disease therapy purposes.

Abstract
Galega officinalis products have been used for the control of diabetes (type 2) across the world. Experimental and clinical evaluations of galegine substance produced by a medicinal plant (Galega officinalis) provided the pharmacological and chemical basis for metformin discovery which was confirmed for diabetes therapy. In this paper, the molecularly imprinted polymer (MIP) was synthesized for galegine, using galegine as a template molecule, methacrylic acid (MAA) as a functional monomer, ethylene glycol dimethacrylate (EGDMA) as a cross-linker, azobisisobutyronitrile (AIBN) as a reaction initiator, and acetonitrile as a solvent. The assisted functional groups, morphology, topographic image of surface, and crystalline structure of synthesized MIP were characterized by FT-IR spectroscopy, field emission scanning electron microscopy (FE-SEM), atomic force microscopy (AFM) images, and XRD diffraction pattern techniques, respectively. Also, the performance of the mentioned electrode was quantified and qualified by the differential pulse voltammetry technique (DPV). The galegine amount was determined with the polarographic technique. In this research, the galegine extraction conditions were optimized and graphene nanoparticles were used to increase the adsorption. In addition, different parameters affecting extraction were investigated such as MIP adsorbent amount, pH of solution, effect of the surfactant, and ionic compound to achieve high recovery percent. The recovery percent, limit of detection (LOD), limit of quantification (LOQ), and relative standard deviation (RSD %) were 4.101 μg·mL-1, 12.427 μg·mL-1, and 1.199% (n = 3), respectively. The results show that the prepared MIP can be used as an effective and inexpensive adsorbent for preconcentration and galegine extraction from a natural sample. It is noteworthy that this developed method was used successfully to determine galegine extracted from Galega officinalis L.

Abstract
BACKGROUND During the last decade, several studies have evaluated the potential association between vitamin D receptor (VDR) gene polymorphism and susceptibility to asthma. In spite of valuable findings, the results are still contradictory. Therefore, a comprehensive meta-analysis not only solves discrepancies but provides a clue for future projects. OBJECTIVE This meta-analysis was performed to identify whether VDR gene polymorphisms (FokI (rs2228570) or TaqI (rs731236) or BsmI (rs1544410) or ApaI (rs7975232)) play a role in the risk of asthma. METHODS Electronic search of Web of Science, Scopus, and PubMed databases were systematically conducted from their inception until June 2019, to identify all published studies. Eligibility of the studies was confirmed by precise inclusion and exclusion criteria, and the resultant studies were analyzed. RESULTS A total of 17 studies concerning VDR gene polymorphisms and asthma risk were included in this meta-analysis. The results of pooled analysis indicated a statistically significant association between FokI SNP (dominant model [OR = 0.78, 95% CI, 0.62-0.98, random effect model] and allelic model [OR = 0.81, 95% CI, 0.67-0.98, random effect model]) and TaqI SNP (homozygote contract model [OR = 0.70, 95% CI, 0.54-0.89]) with asthma risk. Moreover, subgroup analysis showed that ethnicity influences asthma risk in Asian, African, and American populations. The sensitivity analyses confirmed the stability of the results. CONCLUSION This meta-analysis suggests that VDR gene polymorphism is associated with the risk of asthma.

Abstract
Invasion of auto-reactive CD4+ T cells especially Th17 into central nervous system (CNS) is an underlying pathogenic mechanism in multiple sclerosis (MS). CD4+ T cells release exosomes which are enriched in microRNAs, reflective of cell’s physiological or pathological condition. Thus exosomes could be potent agents to provide quantitative and qualitative information about involved cells in MS. We investigated the expression of pathogenic microRNAs in T cells-derived exosomes of MS patients or healthy controls.
Conventional T cells (Tconv) derived from relapsing-remitting (RR) MS patients (n=10) and healthy controls (n=10) were purified and cultured for 3 days by soluble anti-CD3/CD28. Exosomes were purified from cultured-T cells supernatants. The expression levels of exosomal miR-146a, miR-29a, miR-155, and miR-326 were quantified by real-time PCR.
A statistically significant increased expression of miR-326 in Tconv-derived exosomes was observed in RRMS patients as compared with controls (7.5±1.88vs 2.51±0.9 p=0.03), On the contrary, no differences were found in the expression levels of miR-155, miR-146a, and miR-29a, in Tconv-derived exosomes of patients as compared with controls (p>0.05).
Our results point to altered expression in exosome-derived microRNAs. MiR-326 was previously shown to play a role in the immunopathogenesis of MS by inducing TH17 differentiation and maturation. Therefore, miR-326 containing exosomes might also be a potential clinical target in course of MS. Moreover, the deregulation of this miRNA in exosomes may serve as a diagnostic and prognostic biomarker.

Abstract
Background Today, the plant Prosopis farcta is frequently used for traditional medicinal purposes. The aim of this study was the identification of luteolin in P. farcta extract (PFE) and to evaluate its effect on morphine discontinuation syndrome in rats. Material/Methods Using high-performance liquid chromatography (HPCL), luteolin was evaluated in PFE. The frequency of behavioral symptoms of morphine withdrawal (jumping, rearing, and teeth chattering) induced by naloxone challenge were illustrated in morphine-dependent rats receiving PFE, luteolin, saline, or clonidine. LD50 of PFE and luteolin was 540 mg/kg and 150 mg/kg, respectively. Signs of behavioral morphine withdrawal in rats were significantly inhibited by chronic co-administration of PFE, luteolin, or clonidine with morphine. Results This study showed that PFE was less effective than clonidine at a dose of 100 mg/kg, and at doses of 200 mg/kg and 300 mg/kg it was comparable to clonidine, and did not show a significant difference in the reduction of morphine withdrawal symptoms. Luteolin was comparable in 30 mg/kg, 60 mg/kg, and 90 mg/kg with clonidine to reduce the frequency of morphine withdrawal symptoms. PFE can be used as a source of luteolin. Conclusions The study findings suggest that PFE and luteolin might reduce the signs of narcotic withdrawal. Due to a similar effect to clonidine, its mechanism of action might be through the protein kinase A pathway and might have human therapeutic potential.

Abstract
BACKGROUND AND AIM Recent evidence indicates that new approach of the diet with low fermentable oligo-di-mono-saccharides and polyols (FODMAPs) may have an effective role in management of the patients with irritable bowel syndrome (IBS). We compared the results of low FODMAP diet with current dietary treatment, general dietary advices (GDA), on the clinical response in patients with diarrhea subtype of IBS (IBS-D). METHODS In this randomized, controlled, single-blind trial, we included 110 patients with IBS-D in two intervention groups. Participants were randomly assigned to the low FODMAP diet (n = 55) and GDA (n = 55) for 6 weeks after a 10-day screening period. Gastrointestinal symptoms and bowel habit status were evaluated using a symptom severity scoring system and Bristol stool form scale pre-intervention and post-intervention. Patients completed 3-day food diary before and after the intervention. RESULTS Of 110 patients, 101 completed the dietary interventions. At the baseline, the nutrient intake, severity of symptoms, and demographic data were similar between two groups. After 6 weeks, the low FODMAP diet improves significantly overall gastrointestinal symptoms scores, stool frequency, and consistency versus GDA group (P < 0.001, P < 0.001, and P = 0.003, respectively). Compared with the baseline, both intervention groups expressed a significant reduction in overall scores of symptom severity scoring system, abdominal pain, distension, consistency, and frequency, but this reduction is greater in low FODMAP diet group. CONCLUSIONS Both low FODMAP diet and GDA in patients with IBS-D led to adequate improvement of gastrointestinal symptoms for 6 weeks. However, the low FODMAP diet has greater benefits in IBS improvement.

Abstract
OBJECTIVES This study aimed at investigating the effect of Iranian traditional remedy prepared from Apium graveolens and Trachyspermum copticom (AT) on the severity and frequency of symptoms in patients with functional dyspepsia (FD). MATERIAL AND METHODS In total, 150 FD patients were included in this randomized double-blind trial, based on the ROME III diagnostic criteria, and they were divided into three intervention groups namely, AT, Placebo and omeprazole. Then, severity and frequency of symptoms during this eight-week trial were measured. Obtained information was analyzed using Chi-square test and repeated measures test. RESULT In general, the severity and frequency of symptoms after the 4th week significantly decreased in the AT group as compared to the omeprazole and placebo groups, and continued to reduce by the end of the eighth week. General reduction of symptom severity and frequency in the omeprazole group was significantly different from the placebo group by the end of the 4th and 8th weeks. With respect to each individual symptom, AT markedly improved symptoms, such as burning, pain, early satiation, fullness, bloating, belching and nausea, as compared to placebo-treated group. Moreover, AT significantly improved symptoms, like vomiting, and nausea, except for pain, as compared to omeprazole-treated subjects. CONCLUSION According to the results, AT, as Iranian traditional remedy, was more effective than omeprazole and placebo in reducing the symptoms in FD patients.

Abstract
A quantum thermodynamic cycle with a chiral multiferroic working substance such as LiCu_{2}O_{2} is presented. Shortcuts to adiabaticity are employed to achieve an efficient, finite-time quantum thermodynamic cycle, which is found to depend on the spin ordering. The emergent electric polarization associated with the chiral spin order, i.e., the magnetoelectric coupling, renders possible steering of the spin order by an external electric field and hence renders possible an electric-field control of the cycle. Due to the intrinsic coupling between the spin and the electric polarization, the cycle performs an electromagnetic work. We determine this work's mean-square fluctuations, the irreversible work, and the output power of the cycle. We observe that the work mean-square fluctuations are increased with the duration of the adiabatic strokes, while the irreversible work and the output power of the cycle show a nonmonotonic behavior. In particular, the irreversible work vanishes at the end of the quantum adiabatic strokes. This fact confirms that the cycle is reversible. Our theoretical findings evidence the existence of a system inherent maximal output power. By implementing a Lindblad master equation we quantify the role of thermal relaxations on the cycle efficiency. We also discuss the role of entanglement encoded in the noncollinear spin order as a resource to affect the quantum thermodynamic cycle.
