Abstract
To compare the effectiveness of different types of high-intensity interval training (HIIT) on meta-inflammation during obesity, TLR4 pathway activities were assessed following a 10-week randomized trial. 30 young females with overweight and obesity were randomly allocated to aerobic HIIT (HIIT/AE) or resistance exercise in HIIT (HIIT/RE) and performed a 28-minute (4 × 4 min) in each session. During each interval, the HIIT/AE performed four minutes of all-extremity cycling, whereas the HIIT/RE completed four minutes of combined resistance exercises and all-extremity cycling. The TLR4 pathway gene expression was measured for the TLR4 receptor, downstream adaptors (TIR domain-containing adaptor-inducing interferon-β (TRIF) and myeloid differentiation factor (MYD) 88), transcriptional factors (nuclear factor kappa B (NF-κB), and interferon regulatory factor (IRF) 3), and its negative regulator (tumor necrosis factor (TNF) a-induced protein 3 (TNFAIP3)). The serum levels of TNFα, interferon (IFN) γ, interleukin (IL)-10, and adiponectin were measured. We found that TLR4 (HIIT/RE: 0.6 ± 0.43 vs. HIIT/AE: 1.24 ± 0.82, p = 0.02), TRIF (HIIT/RE: 0.51 ± 0.4 vs. HIIT/AE: 3.56 ± 0.52, p = 0.001), and IRF3 (HIIT/RE: 0.49 ± 0.42 vs. HIIT/AE: 0.6 ± 0.89; p = 0.04) levels were significantly downregulated in HIIT/RE compared to the HIIT/AE, with a significant reduction in serum levels of TNFα (pg/ml) (HIIT/RE: 22.5 ± 11.3 to 6.3 ± 5.3 vs. HIIT/AE: 19.16 ± 20.8 to 13.48 ± 21.7, p = 0.04) and IFNγ (pg/ml) (HIIT/RE: 43.5 ± 20.6 to 37.5 ± 4.3 vs. HIIT/AE: 37.6 ± 5.6 to 68.1 ± 22.5, p = 0.03). Adiponectin and IL-10 levels did not significantly differ between the two groups. Thus, resistance exercise training augments the immunomodulatory adaptations to HIIT and should be prescribed to people at risk of cardiometabolic disease.Highlights HIIT in combination with resistance exercise looks more effective than HIIT alone to target TLR4-mediated inflammation in individuals with overweight and obesity.HIIT/RE induces a different effect on two downstream cascades of TLR4, leading to a greater overall reduction of TRIF-dependent pathway activities compared to MYD88.Both HIIT protocols show comparable effects on the negative regulatory protein TNFAIP3 gene expression.

Abstract
Background Natural killer T (NKT) cells are influential immune cells in pregnancy failures, including recurrent spontaneous abortion (RSA). Different approaches are used for these disorders due to their effects on maternal immunomodulation. Aims In the present study, we compared the effects of two typical immunotherapies (lymphocyte immunotherapy [LIT] and low-dose prednisolone) on CD3+CD56+CD16+ and CD3+CD56+CD8+ cells as two distinct subsets of NKT cells in Women with RSA. Settings and Design This study was a comparative cohort study conducted from 2021 to 2022. One hundred and five women with RSA were distributed into three treatment groups randomly. Materials and Methods Fifty women in the group of low-dose prednisolone therapy, fifty women in the LIT group and five women without any treatment as the control group were included in the study. NK and NKT cell subsets were assessed using flow cytometry. Furthermore, the concentration of interferon-gamma (IFN-γ), transforming growth factor-beta (TGF-β) and interleukin-10 (IL-10) was measured quantitatively using the enzyme-linked immunosorbent assay technique. Statistical Analysis Used Normality and comparisons between study groups were performed by non-parametric unpaired Mann-Whitney, Kruskal-Wallis rank sum test, and one-way ANOVA. Results The percentage of CD56dim NK cells was increased after prednisolone therapy, while this population significantly decreased in the LIT group. In contrast to the LIT group, the administration of prednisolone increased CD3+CD8+CD56+ NKT cells (P < 0.0001), which is helpful for pregnancy. The effect of the investigated treatment approaches on the population of peripheral CD3+CD56+CD16+ NKT cells of women with RSA was not adequately significant. The same situation was also observed regarding the serum level of IFN-γ. However, a significant decrease in serum levels of IL-10 and TGF-β was observed after prednisolone therapy. Conclusion The lower capability of LIT in changing the population of NKT cells compared to prednisolone therapy may be due to its mechanism of action, which is related to the production of blocking antibodies. These treatment approaches had different effects on NKT cells, indicating that NKT cell population and function can be affected using LIT and prednisolone therapy distinctly. In addition, prednisolone therapy and LIT in women with normal serum levels of IFN-γ have no harmful effects in changing the production of this critical cytokine.

Abstract
OBJECTIVES PD1/PDL1 pathway targeting using antibodies shows immune related adverse events in patients with tumors. The masking of PD1 ligand by soluble human PD-1 (shPD-1) probably inhibits the PD1/PDL1 interaction between T cells and tumor cells. Accordingly, the goal of this study was to produce human recombinant PD-1-secreting cells and find out how soluble human PD-1 affects T lymphocyte function. METHODS An inducible construct of the human PD-1 secreting gene under hypoxia condition was synthesized. The construct was transfected into the MDA-MB-231 cell line. In six groups exhausted T lymphocytes were co-cultured with transfected or non-transfected MDA-MB-231 cell lines. The effect of shPD-1 on IFNγ production, Treg cell's function, CD107a expression, apoptosis, and proliferation was assessed by ELISA and flow cytometry, respectively. RESULTS The results of this study showed that shPD-1 inhibits PD-1/PD-L1 interaction and enhances T lymphocyte responses through a significant increase in IFNγ production and CD107a expression. In addition, in the presence of shPD-1, the percentage of Treg cells decreased, while MDA-MB-231 cell apoptosis increased. CONCLUSIONS We concluded that the human PD-1 secreting construct induced under hypoxia condition inhibits the interaction of PD-1/PD-L1 and enhances T lymphocyte responses in tumor environments and chronic infections.

Abstract
In current study, a new remotely controlled drug delivery, radio-sensitizing, and photothermal therapy agent based on thioglycolic acid modified bismuth nanosheets is thoroughly evaluated. Bismuth nanosheets were synthesized using sodium borohydride (NaBH4) and Tween 20 through low energy (400 W) sonication within 2 h. The resultant nanosheets were 40-60 nm in size and 1-3 atomic layers in thickness. The morphological and structural characteristics of the nanosheets were studied using transmission electron microscopy, high-resolution transmission electron microscopy, X-ray diffraction, Raman spectroscopy and ultraviolet spectroscopy. The surface of the nanosheets was modified using thioglycolic acid, which resulted in enhanced Mitomycin C loading capacity to 274.35% and circumvented the burst drug release due to the improved electrostatic interactions. At pH 7.4 and 5.0, the drug release was significantly boosted from 45.1 to 69.8%, respectively. Thioglycolic acid modified bismuth nanosheets under 1064 nm laser irradiation possessed photothermal conversion efficiency of η=51.4% enabling a temperature rise of 24.9 °C at 100 μg/ml in 5 min. The combination of drug delivery, photothermal therapy, and radio-sensitization greatly damaged the MDA-MB-231 cells through apoptosis and diminished their colony forming.

Abstract
The induction of feto-maternal tolerance, fetal non-immunogenicity, and the regulation of mother's immune system are essential variables in a successful pregnancy. Fetal membranes have been used as a source of stem cells and biological components in recent decades. Human amniotic epithelial cells (hAEC) have stem/progenitor characteristics like those found in the amniotic membrane. Based on their immunomodulatory capabilities, recent studies have focused on the experimental and therapeutic applications of hAECs in allograft transplantation, autoimmune disorders, and gynecological problems such as recurrent spontaneous abortion (RSA), recurrent implantation failure (RIF), and premature ovarian failure (POF). This review discusses some of the immunomodulatory features and therapeutic potential of hAECs in preventing infertility, miscarriage, and implantation failure by controlling the maternal immune system.

Abstract
Natural killer (NK) cells are unique innate immune cells that mediate anti-viral and anti-tumor responses. Thus, they might hold great potential for cancer immunotherapy. NK cell adoptive immunotherapy in humans has shown modest efficacy. In particular, it has failed to demonstrate therapeutic efficiency in the treatment of solid tumors, possibly due in part to the immunosuppressive tumor microenvironment (TME), which reduces NK cell immunotherapy's efficiencies. It is known that immune checkpoints play a prominent role in creating an immunosuppressive TME, leading to NK cell exhaustion and tumor immune escape. Therefore, NK cells must be reversed from their dysfunctional status and increased in their effector roles in order to improve the efficiency of cancer immunotherapy. Blockade of immune checkpoints can not only rescue NK cells from exhaustion but also augment their robust anti-tumor activity. In this review, we discussed immune checkpoint blockade strategies with a focus on chimeric antigen receptor (CAR)-NK cells to redirect NK cells to cancer cells in the treatment of solid tumors.

Abstract
Innate immunity, as the first line of defense of our immune system, plays a crucial role in defending against SARS-CoV-2 infection and also its immunopathogenesis. We aim to investigate the immune status of natural killer (NK) cells, natural killer T (NKT) cells, and NLRP3 gene expression in COVID-19 patient blood samples. The immunophenotype of NK cell subsets and NKT cells was detected by flow cytometry and the expression of NLRP3 gene assessed by reverse transcriptase real-time polymerase chain reaction in 44 COVID-19 patients and 20 healthy individuals. The percentage of most of NK cell subpopulation and NKT cells was significantly decreased in COVID-19 patients. The percentage of CD56dim CD16- NK cell subsets, and NLRP3 gene expression increased. The percentage of total NK cells, CD56+ CD16+ NK cells, and NLRP3 gene expression had acceptable sensitivity and specificity for assisting diagnosis of severe/critical COVID-19. O2 saturation% and lactate dehydrogenase levels showed valuable diagnostic value to identify critical cases. The declined NK and NKT cells in COVID-19 patients and enhanced NLRP3 gene expression were associated with disease severity. Total NK cells, CD56+ CD16+ NK cells, and NLRP3 gene expression might be used as meaningful indicators for assisting diagnosis of severe/critical COVID-19.

Abstract
Abnormal iron accumulation in vital organs is one of the major complications of β-thalassemia intermedia (β-TI). Silymarin, a flavonolignan isolated from Silybum marianum, significantly decreases the serum ferritin levels of β-TI patients. This finding suggests silymarin as a safe and effective natural iron-chelating agent for the treatment of iron-overloaded conditions.

Abstract
Background: Carvacrol is a natural phenolic monoterpene with anti-inflammatory and antioxidant bioactivities. Neuroinflammatory and oxidative stress responses play a crucial role in the pathogenesis of Alzheimer's disease. The present study examined the effect of carvacrol on brain tumor necrosis factor-alpha (TNF-α) level and oxidative stress as well as spatial learning and memory performances in lipopolysaccharide (LPS)-exposed rats. Materials and Methods: The rats were treated with either carvacrol (25 and 50 mg/kg) or Tween 80 for 2 weeks. Thereafter, LPS (1 mg/kg) or saline was intraperitoneally administered on days 15–19, 2 h before Morris water maze task, and treatments with carvacrol or Tween 80 were performed 30 min prior to behavioral testing. The level of TNF-α, lipid peroxidation, and total thiol concentration were measured in the hippocampus and cerebral cortex at the end of the experiment. Results: It was found that LPS-exposed rats exhibited spatial learning and memory dysfunction, which was accompanied by increased TNF-α level and lipid peroxidation, and decreased total thiol concentration in the hippocampus and/or cortex. Moreover, treatment with carvacrol at a dose of 25 mg/kg attenuated learning and memory impairments, decreased TNF-α and lipid peroxidation level in the hippocampus and cortex, and increased total thiol concentration in the cortex. Conclusion: Carvacrol exerts neuroprotective effects against LPS-induced spatial memory deficits through attenuating hippocampal TNF-α level and oxidative stress in rats.

Abstract
Background and purpose: The use of anti-CD20 monoclonal antibodies like rituximab (RTX) to deplete B cells has practical therapeutic implications in multiple sclerosis (MS) patients. However, the therapy’s impact on other immune cells is also important. Therefore, in this study, we assessed the effects of RTX therapy on Tfh cells, T cells, T cells priming, and monocytes in MS patients compared to newly-diagnosed MS patients and healthy subjects. Experimental approach: Thirty newly-diagnosed and RTX-treated MS patients and healthy control were included. Peripheral blood mononuclear cells were isolated from whole blood for assessment of Tfh cells, CD4+, CD8+, CD4+CD45RA+, CD3+HLA-DR+, and CD3+CD4+CD25+ T cells by flow cytometry. Whole blood was lysed by lysis solution to assess CD45+CD14+ monocytes by flow cytometry. Also, the serum level of interleukin 21 was measured by the ELISA method. Findings / Results: We showed that RTX treatment led to a decrease in Tfh cells and their predominant cytokine, interleukin 21. Also, we found a statistically significant reduction in CD3+HLA-DR+ and CD3+CD4+CD25+ T cells in RTX-treated patients compared to new cases and healthy control. Moreover, we found a decrease in the CD45+ CD14+ monocyte population in the RTX-treated group compared to the healthy control. Conclusion and implications: Our data suggest that following treatment with RTX, Tfh cells, monocytes, and T cells priming declined happened, and fewer T cells were activated. Also, due to the interaction between B cells and Tfh cells, Tfh targeting could be assessed as a therapeutic strategy in MS.

Abstract
The association between air pollution and multiple sclerosis (MS) is not entirely clear. This meta-analysis was aimed at determining the correlation between particulate matter (PM)2.5, PM10, and MS incidence/relapse. The literature search was performed in EMBASE, Web of Science, PubMed, and the gray literature. Sixteen articles were retrieved, and ten articles were included and evaluated. Three measures of association were used for the meta-analysis: odds ratio (cross-sectional and case-control studies), incidence rate ratio, or hazard ratio (cohort studies). Meta-analysis of those 3 studies on PM2.5 indicated that exposure to PM2.5 was associated with MS relapse and incidence ([95% confidence interval; CI] 1.178 [1.102, 1.279]), p > 0.05. Also, assessment of risk ratio for all studies showed a correlation between PMs (PM10 and PM2.5) and MS incidence and relapse ([95% CI] 1.28, [1.13-1.43]) p < 0.05. Collectively, we found that PM exposure (PM10 and PM2.5) in MS patients associates with the occurrence and relapse of disease.

Abstract
Background and purpose: One of the most effective methods for the development of dendritic cell (DC)-based cancer immunotherapy is ex vivo pulsing of DCs with tumor cell lysates (TCLs). However, antitumor immune responses of DCs are significantly influenced by how TCLs were prepared. Here, we compared four strategies of TCL preparation derived from colon cancer cells, HT-29, for ex vivo maturation of DCs. Experimental approach: Peripheral blood monocytes were isolated from healthy volunteers and incubated with granulocyte macrophage colony-stimulating factor and interleukin (IL)-4 to differentiate into DCs in 10 days. Morphological properties, phenotype characteristics (i.e. CD83 and CD86), and cytokine production (i.e. IL-10 and interferon gamma) of DCs loaded with four different TCLs (i.e. freeze-thaw, hypochlorous acid (HOCl), hyperthermia, and UV irradiation) were evaluated. Findings/Results: HOCl preparations led to the generation of DCs with higher surface expression of maturation biomarkers (particularly CD83), while UV preparations resulted in DCs with lower levels of surface biomarkers compared to freeze-thawed preparations. The supernatant of DCs pulsed with HOCl preparation showed significantly higher levels of interferon gamma and lower levels of IL-10 compared with the other groups. Conclusion and implications: Our results suggest that pulsing DCs with HOCl preparation may be superior to other TCLs preparation strategies, possibly due to induction of rapid necrotic cell death.

Abstract
Multiple sclerosis (MS) is a demyelinating inflammatory disorder of the central nervous system (CNS). Besides the vital role of T cells, other immune cells, including B cells, innate immune cells, and macrophages (MФs), also play a critical role in MS pathogenesis. Tissue-resident MФs in the brain’s parenchyma, known as microglia and monocyte-derived MФs, enter into the CNS following alterations in CNS homeostasis that induce inflammatory responses in MS. Although the neuroprotective and anti-inflammatory actions of monocyte-derived MФs and resident MФs are required to maintain CNS tolerance, they can release inflammatory cytokines and reactivate primed T cells during neuroinflammation. In the CNS of MS patients, elevated myeloid cells and activated MФs have been found and associated with demyelination and axonal loss. Thus, according to the role of MФs in neuroinflammation, they have attracted attention as a therapeutic target. Also, due to their different origin, location, and turnover, other strategies may require to target the various myeloid cell populations. Here we review the role of distinct subsets of MФs in the pathogenesis of MS and different therapeutic agents that target these cells.

Abstract
Multiple sclerosis (MS) is a chronic demyelinating disease of the central nervous system presented by autoimmune manifestations. This study aimed at investigating the effects of apamin administration on the activated T cell population in an experimental autoimmune encephalomyelitis (EAE) MS model. Thirty mice underwent EAE induction and were then randomly divided into 5 groups. Three groups received 10, 50, and 100 µg/kg apamin; the fourth group received 1 mg/kg dexamethasone; and the fifth group received the equivalent amount of PBS (phosphate-buffered saline) intraperitoneally. Peripheral CD4 + cell and memory T cell distribution was measured with a flow cytometer every week. Also, CD4 + and CD8 + cell infiltration to the brain was assessed with immunohistochemistry. It was observed that the group receiving 50 µg/kg apamin had a lower EAE score in comparison with the groups receiving 100 µg/kg apamin (p 0.014). Also, peripheral blood memory cells with CD44 + , CD62L - , and CD4 + markers were decreased in apamin-administered groups. Regarding the infiltrated CD8 + cells, a significant decrease (p 0.002) was observed in the group receiving 50 µg/kg apamin compared with the control group. These results indicate that 50-µg/kg doses of apamin had an effective treatment over 14 days; it reduced both the severity of symptoms and the infiltration of CD8 + cells into the CNS. Moreover, it increased myelin density and decreased the circulation of CD62L - , CD44L - , and CD44 + memory T cells. So, it appears that apamin plays a critical role in regulating immunity and reducing the complications of autoimmune MS.

Abstract
Background: The absence of Aquaporin-4 Antibody (AQP4-Ab) in a fraction of the Neuromyelitis Optica Spectrum Disorder (NMOSD) patients has led to a search for other serologic markers. Myelin Oligodendrocyte Glycoprotein (MOG) is a protein component of the myelin sheets encapsulating the neural fibers. Objectives: We aimed to compare the presence and levels of anti-MOG (Ig-G) in a group of seronegative NMOSD patients with a healthy control group. Materials & Methods: In this cross-sectional study, 30 NMOSD patients with negative AQP-Ab status, who were referred to the Neurology Clinic of Kashani University Hospital in Isfahan City, Iran, from March 2015 to March 2016, and 26 healthy controls were consecutively recruited. Their baseline demographic and clinical data were recorded. Serum anti-MOG levels were measured in both groups. The obtained data were analyzed using the Student t-test, Mann-Whitney U, and Chisquare test in SPSS V. 18. Results: The anti-MOG test results were statistically higher in patients (n=12, 37.5%) compared to controls (n=0, 0%) (P<0.0001). The level of anti-MOG in Healthy Control (HC) was higher compared to patients with negative anti-MOG (P<0.0001) and was lower than patients with positive anti-MOG (P<0.0001). Conclusion: Our study showed that nearly one-third of seronegative NMOSD patients were positive for MOG-Ab. Further studies are needed to assess the characteristics and outcome of these patients.

Abstract
OBJECTIVE The effects of exercise training on suppression of inflammation have been proposed as a therapeutic approach in recent years to modify the obesity-induced inflammatory status and immunometabolic disorders. The present study aimed to assess the impacts of an all-extremity combined high-intensity interval training (HIIT) on inflammatory state and glycolipid metabolism in young sedentary overweight and obese females. METHOD This was an quasi-experimental study which was applied by comparing two groups. The participants were allocated to two active (AG, n = 15) and inactive (IG, n = 15) groups. The serum level of adiponectin, interleukin (IL)-10, pentraxin 3 (PTX3), and tumor-necrosis factor α (TNFα) was measured in all subjects. Also, glycolipid metabolism was assessed by measuring the fasting lipid profile parameters, glucose, and insulin levels and calculating the homeostasis model assessment of insulin resistance (HOMA2-IR). RESULTS Following a 10-week combined all-extremity HIIT in the active subjects, the TNFα, PTX3/IL-10, and TNFα/adiponectin were significantly reduced. However, the absolute levels of adiponectin, IL-10, and PTX3 remained unchanged. Additionally, a significant decrease was found in insulin, LDL, and HOMA2-IR, while insulin sensitivity and HDL levels showed a significant increase in the active group compared to the inactive group. CONCLUSIONS Our 10-week time-efficient combined all-extremity HIIT promoted an anti-inflammatory state and glycolipid metabolism improvement, suggesting this protocol as a practical therapeutic approach in sedentary obese females.

Abstract
Common variable immunodeficiency (CVID) is a primary immune deficiency disorder characterized by a failure in B cell differentiation, impaired immunoglobulin production,and defect in response to vaccines. As a result of defective B cell maturation and differentiation in CVID, the affected patients commonly present with reduced numbers of memory B cell and antibody-secreting plasma cells. B-cell lymphoma 6 protein (BCL6) and B lymphocyte induced maturation protein 1 (BLIMP1) molecules are two important transcription factors that have key roles in the maturation of B cells to plasma cells. Hence, in the current survey, we aimed to evaluate the mRNA and protein expression levels of BCL6 and BLIMP1 in B lymphocytes isolated from peripheral blood in CVID patients. We collected blood samples from 12 CVID patients and 12 healthy controls. We isolated peripheral blood mononuclear cells (PBMCs) using Ficoll density gradient separation. Then, CD19+ B cells were purified using MACS. The protein expression and transcriptional level of BCL6 and BLIMP1 were respectively measured using flow cytometry and real-time PCR. Our results showed that the BLIMP1 mRNA expression, as well as BLIMP1 protein expression, were significantly higher in CVID patients compared to control subjects (p=0.009 and p=0.007, respectively). However, we found no significant difference in mRNA and protein expression of BCL6 between patients and healthy controls. According to our findings, increased mRNA and protein expression levels of BLIMP1 could be involved in defective maturation of B cells in patients with CVID and elucidate mechanistic insights into the pathogenesis of this disorder.

Abstract
Environmental exposure to diesel particulate matter and commercial gasoline in gas station workers might induce oxidative stress and changes in the balance of the immune system. In this study, the immunomodulatory impacts of omega 3 fatty acid (ω3FA) supplement were assessed on inflammatory and anti-inflammatory markers in gas station workers in a double-blind placebo-controlled clinical trial. Fifty-three men working in gas stations were treated with ω3FA (n = 29) or placebo (n = 24) for 60 days. C-reactive protein, interleukin-12 (IL-12), transforming growth factor β (TGF-β), interferon γ (IFN-γ), tumor necrosis factor α, IL-10, and IL-17 levels were measured by enzyme-linked immunosorbent assay method before and after the completion of the trial. The concentrations of IFN-γ and IL-17 were significantly decreased in ω3FA group compared with the placebo group (P < 0.001). Moreover, the levels of inhibitory cytokines including TGF-β and IL-10 significantly were increased in ω3FA group (P < 0.001). Overall, ω3FA nutritional supplementation can be useful in reducing inflammatory immune responses and maintaining immune tolerance in people with high exposure to inflammation-inducing factors.

Abstract
Reduced physical activity rate in people's lifestyle is a global concern associated with the prevalence of health disorders such as obesity and metabolic disturbance. Ample evidence has indicated a critical role of the immune system in the aggravation of obesity. The type, duration, and production of adipose tissue-released mediators may change subsequent inactive lifestyle-induced obesity, leading to the chronic systematic inflammation and monocyte/macrophage (MON/MФ) phenotype polarization. Preliminary adipose tissue expansion can be inhibited by changing the lifestyle. In this context, exercise training is widely recommended due to a definite improvement of energy balance and the potential impacts on the inflammatory signaling cascades. How exercise training affects the immune system has not yet been fully elucidated, because its anti-inflammatory, pro-inflammatory, or even immunosuppressive impacts have been indicated in the literature. A thorough understanding of the mechanisms triggered by exercise can suggest a new approach to combat meta-inflammation-induced metabolic diseases. In this review, we summarized the obesity-induced inflammatory pathways, the roles of MON/MФ polarization in adipose tissue and systemic inflammation, and the underlying inflammatory mechanisms triggered by exercise during obesity.

Abstract
Both heroin abuse and early life stress (ELS) affect the immune system and the hypothalamic-pituitary-adrenal (HPA) axis. Additionally, accelerated aging due to mild inflammation has been indicated in these conditions. The present study aims to compare plasma levels of apoptosis markers, inflammatory markers, and stress hormones during early heroin abstinence period. Thirty-one individuals with heroin/opioid use disorder who had heroin-ELS and 26 of their siblings who were not abusing substances (ELS), and 32 individuals with heroin/opioid use disorder without a history of ELS (heroin-no ELS) were included in the study. The levels of interleukin-6, C-reactive protein, erythrocyte sedimentation rate, albumin, alanine transaminase, aspartate transaminase, and white blood cell count were assessed as the inflammatory and biochemistry markers. Also, apoptosis markers including tumor necrosis factor (TNF)-related weak inducer of apoptosis, TNF-related apoptosis-inducing ligand, soluble tumor necrosis factor receptor type I as apoptosis markers were detected by enzyme-linked immunosorbent assay. ELS was simultaneously evaluated using the Childhood Trauma Questionnaire, Minnesota Multiphasic Personality Inventory, and beck depression inventory scales. Besides, heroin craving was assessed by Daily Drinking/Drug Questionnaire score in individuals with heroin use disorder. This is the first study to evaluate the inflammatory, stress, and apoptosis markers during heroin abstinence, supporting the association between ELS and peripheral pro-inflammatory markers' levels and HPA axis.

Abstract
Metainflammation and malfunctions of toll-like receptor 4 (TLR4) are related to obesity-induced immunometabolic morbidities. There are almost no studies relating exercise training to the TLR4 pathway and its adaptors and negative regulators. Thirty young women with obesity (exercise group and control group) were included in a 10-week all-extremity combined high-intensity interval training program. The immunomodulatory impacts of exercise on TLR4, its related adaptors (TIR domain-containing adaptor-inducing IFN-β[TRIF], myeloid differentiation factor 88 [MyD88],and tumor receptor-associated factor 6 [TRAF6]), transcriptional factors (nuclear factor [NF]-κB and interferon regulatory factor 3 [IRF3]), and negative regulator (A20) mRNA levels were assessed by real-time PCR. Also, the serum concentration of TLR4 final products (tumor necrosis factor α [TNFα] and interferon γ [IFNγ]) was measured by ELISA. Cardiorespiratory and body composition parameters were tested, as well. There was a significant improvement in body composition and cardiorespiratory fitness. This intervention downregulated TLR4 (from 2.25 ± 1.07 to 0.84 ± 1.01), MyD88 (from 4.53 ± 5.15 to 1.27 ± 0.88), NF-κB (from 1.61 ± 2.03 to 0.23 ± 0.39), IRF3 (from 1.22 ± 0.77 to 0.25 ± 0.36), and A20 (from 0.88 ± 0.59 to 0.22 ± 0.33) levels and reduced the TNFα concentrations (from 22.39 ± 11.43 to 6.26 ± 5.31) significantly in the exercise group, while no statistically significant change was found in TRIF and TRAF6 expression and IFNγ circulating levels. It is concluded that long-term exercise modifies the inflammatory pathways and modulates the immune function at the early stages of inflammation initiation in circulating immune cells. Accordingly, we suggest time-efficient exercise protocols as a possible therapy approach for the prevention of M1 polarization.

Abstract
BACKGROUND Regarding to the increase of cancer deaths in recent years and disability of common therapies to eradicate cancers, as well as expansion of Natural Killer (NK) cell therapy, it seems so vital to find new useful therapies against cancers. Breast cancer is the second main cause of cancer death among women. As it is impossible for a majority of patients to receive NK cell therapy, an attempt was made to establish a low-cost and efficient method for expanding and activating NK cells against breast cancer cell line (MCF7). METHODS NK cells were isolated from Peripheral Blood Mononuclear Cells (PBMCs) applying either MACS based NK cell enrichment kit or antibodies and complement as cytotoxic method. Then, the NK cells were cultured in Stem Cell Growth Medium (SCGM) with feeder layer (irradiated PBMCs) along with PHA or OKT3. IL-2, IL-15 and IL-21 were used to expand NK cells and finally their cytotoxic activity was investigated by flow cytometry. RESULTS Highly pure NK cells were obtained and no significant difference between the two isolation methods was found. Using IL-2 plus IL-15, the number of NK cells increased up to100 fold after 16 days. No significant effect was observed after IL-21 treatment. CONCLUSION Our data indicated that cytotoxicity method can be considered a low-cost alternative for NK cell isolation kits. It seems that culturing NK cells for 14 days in either PHA or OKT3 supplemented SCGM medium would be more effective than culturing for 16 days in the presence of IL-21.

Abstract
BACKGROUND Programmed cell death protein-1 (PD-1)/PD-L1 pathway is one of the immune checkpoint pathways involved in the regulation of the immune responses and the suppression of anti-tumor defense. PD-1/PD-L1 blocking antibodies improve immune responses such as cytotoxic activity of CD8+/CD4+T cells and increase mortality of tumor cells as well; however, their use is accompanied by adverse side effects. OBJECTIVES We aimed to produce a native blocker of human PD-1/PD-L1, for developing T cells cytotoxicity and tumor cells apoptosis. MATERIALS AND METHODS We designed and cloned soluble human PD-1-GFP-pcDNA3.1/hygro construct in Escherichia coli strain TOP10 cells and then transfected this construct into the HEK cells. The concentration of the secreted shPD-1 in the supernatant was measured and the supernatant was used for blocking PD-L1 on the MDA-MB-231 cells. The cytotoxicity of CD8+/CD4+T cells and the apoptosis of MDA-MB-231 cells, under the influence of shPD-1 in the co-culture of T cells with the MDA-MB-231 cells, were evaluated using flow cytometry technique. RESULTS The GFP expression in the transfected cells illustrated the successful designing, transfection, and production of shPD-1. Soluble human PD-1 concentration in the supernatant of the transfected HEK cells was significantly higher than the untransfected cells. In addition, shPD-1 significantly blocked PD-L1 on the MDA- MB-231 cells, improved the cytotoxicity of CD4+T cells, and increased the apoptosis of MDA-MB-231 cells. CONCLUSION Overall, increased CD4+T cell cytotoxicity and tumor cells apoptosis under the influence of shPD-1, confirmed the effectiveness of shPD-1 as a natural blocker of PD-L1and as an augmenter of the anti-tumorimmune responses.

Abstract
Granulocyte-macrophage colony-stimulating factor (GM-CSF) was first described as a growth factor that induces the differentiation and proliferation of myeloid progenitors in the bone marrow. GM-CSF also has an important cytokine effect in chronic inflammatory diseases by stimulating the activation and migration of myeloid cells to inflammation sites, promoting survival of target cells and stimulating the renewal of effector granulocytes and macrophages. Because of these pro-cellular effects, an imbalance in GM-CSF production/signaling may lead to harmful inflammatory conditions. In this context, GM-CSF has a pathogenic role in autoimmune diseases that are dependent on cellular immune responses such as multiple sclerosis (MS) and rheumatoid arthritis (RA). Conversely, a protective role has also been described in other autoimmune diseases where humoral responses are detrimental such as myasthenia gravis (MG), Hashimoto's thyroiditis (HT), inflammatory bowel disease (IBD), and systemic lupus erythematosus (SLE). In this review, we aimed for a comprehensive analysis of literature data on the multiple roles of GM-CSF in autoimmue diseases and possible therapeutic strategies that target GM-CSF production.

Abstract
The regulatory role of interleukin (IL) -35 in the immunopathogenesis of multiple sclerosis (MS) is suggested in very few studies. We aimed to measure serum levels of IL-35 among clinically isolated syndrome (CIS) and relapsing-remitting MS (RRMS) patients and evaluate the associations between this cytokine and the disease clinical course. This cross-sectional study was conducted during 2017 in a referral university clinic. Forty patients and 40 healthy controls were included in the study. The level of IL-35 in the serum of all subjects was determined by ELISA. Serum level of IL-35 was reduced (p = 0.003) in RRMS in comparison with healthy controls. Moreover, the mean serum level of IL-35 among new cases (diagnosed within the 6 months prior to the study) decreased compared to healthy controls but it was not statistically significant (P=0.059). The mean serum level of IL-35 was significantly higher in new cases compared with other cases (p=0.048). Overall, we found decreased serum level of IL-35 among RRMS patients compared to the healthy controls. Our finding provides a view of the possible role of IL-35 in MS pathogenesis and the potential therapeutic targets.

Abstract
Background Toxocariasis is a common parasitic infectionworldwide even in developed countries. Through this health problem, the immune system is triggered and the antibody is produced, leading to some hypersensitive situations like asthma. In the present study, we tried to show a correlation between Toxocara Canis (T. canis) seropositivityand asthma in Isfahan city. Methods This research is a cross-sectional study involving 40 asthmatics and 46 non-asthmatic cases aged 2-18 years. In all cases, T. canis IgG level was measured using enzyme-linked immunosorbent assay (ELISA) and compared between two groups. Results The seroprevalence of IgG anti-T. canis antibodies were 45%in the asthmatic patients and 21.7% in thecontrols (P= 0.022). The more severe asthmatic patients had significantly more risk for T. canis seropositivity (P= 0.019). In the asthmatic patients, there was a significant correlation between Toxocara seropositivity and goingto park or playground (P= 0.001). Conclusion In this study, we found a significantly positive serology of T. canis in asthmatic children especially in more severe disease. To verify the etiologic role of Toxocara in asthma, more advanced studies are needed.

Abstract
OBJECTIVES Myasthenia gravis (MG) is an autoimmune disease accompanied by a thymic pathology and in most patients thymectomy (TE) is used as the therapeutic approach. Both B and T cells play an important role in MG pathogenesis. METHODS Twelve pre- and post-TE MG patients and 12 healthy controls (HCs) were enrolled. The mean percentages of Th22 and Tc22 cells were evaluated in MG patients (before and 6 months after TE) and HCs. RESULTS The mean percentage of Tc22 cells in pre-TE patients was significantly higher than in HCs (p < 0.05), and after TE Tc22 cells significantly decreased compared to pre-TE (p < 0.05). The frequency of Th22 cells in pre-TE MG patients was not significantly different from HCs, but after TE Th22 cells were significantly decreased compared to pre-TE (p < 0.05). CONCLUSION Our findings suggest a possible role of Th22 and Tc22 in MG pathogenesis.

Abstract
Objective Human amniotic epithelial cells (hAECs) which are isolated from the amniotic membrane have stem cell-like properties and immunomodulatory effects. Several protocols have been proposed for isolation of hAECs, nevertheless, there is no report concerning isolation of highly viable hAECs, with desirable yield, and without significant purity reduction. In the current study, a detailed protocol with some modification of previous ones is presented in which the amendments led to isolation of hAECs with high purity, yield and viability. Moreover, isolated hAECs were subjected to immuno-phenotyping and their physiological status was assessed using a proliferation assay. Results The average yield of obtained hAECs using the new modified method was 190 × 106 cells with a mean viability of 87%, with less than 1% contamination with mesenchymal stem cells (MSCs). The isolated cells were > 95% positive for the epithelial cell markers. The lowest initial plating efficiency of the cells was 80%. Freshly isolated hAECs had the ability to proliferate for 5–6 passages in a standard culture medium.

Abstract
Background: The objective of this study is to indicate the role of urokinase plasminogen activator receptor (uPAR), soluble uPAR (suPAR), and β1 integrin in tumor growth and invasion of lymph nodes from Hodgkin's lymphoma (HL) patients. Materials and Methods: In this study, 25 lymph nodes from HL patients were analyzed for the expression of β1 integrin and uPAR on mononuclear cells using two-color flow cytometry and immunohistochemical analysis. Moreover, the levels of suPAR in the serum samples of HL patients were measured and compared with 32 healthy controls. Results: Flowcytometry and immunohistochemical results indicated no significant association of uPAR expression with tumor size, different stages, or different histological subtypes of HL; however, an increased expression of β1 integrin was detected in the advanced stages of HL. Higher expression of β1 integrin was detected in nodular sclerosis compared to lymphocyte predominant. No significant difference was observed between the serum levels of suPAR in patients with different stages of HL and healthy controls. Moreover, the levels of suPAR were significantly higher in nodular sclerosis in comparison with other subtypes. Conclusions: This study showed that the levels of suPAR and β1 integrin varied between different histological subtypes of HL. Although uPAR may play only a minor role in the growth and metastasis of lymphoma, β1 integrin may be important in predicting prognosis and metastasis in HL.

Abstract
Silymarin is a flavonoid complex extracted from the Silybum marianum plant. It acts as a strong antioxidant and free radical scavenger by different mechanisms. But in addition to antioxidant effects, silymarin/silybin reveals immunomodulatory affects with both immunostimulatory and immunosuppression activities. Different studies have shown that silymarin has the anti-inflammatory effect through the suppression of NF-κB signaling pathway and TNF-α activation. It also has different immunomodulatory activities in a dose and time-dependent manner. As an immunomodulator agent, silymarin inhibits T-lymphocyte function at low doses while stimulates inflammatory processes at high doses. Studies have shown that silymarin has attenuated autoimmune, allergic, preeclampsia, cancer, and immune-mediated liver diseases and also has suppressed oxidative and nitrosative immunotoxicity. Silymarin also has indicated dual effects on proliferation and apoptosis of different cells. In conclusion, based on the current review, silymarin has a broad spectrum of immunomodulatory functions under different conditions. Recognizing the exact mechanisms of silymarin on cellular and molecular pathways would be very valuable for treatment of immune-mediated diseases. Also further studies are needed to assess the utility of silymarin in protection against autoimmune, cancer, allergic and other diseases in human subjects.

Abstract
Triple negative breast cancer (TNBC) is the most lethal and aggressive kind of breast cancer. Studies with TNBC cells suggest that tumor environmental cytokines such as Transforming Growth Factor β1 (TGF-β1) have important roles in tumors fate. In the present study, we aimed to investigate, the effect of phosphatidylinositol 3-kinase/AKT/mammalian target of rapamycin (PI3K/Akt/mTOR) signaling pathway dual inhibitor, NVP-BEZ235 and Caffeic acid phenyl ester (CAPE) on TNBC cell line (MDA-MB-231), stimulated with TGF-β1 for 14days in vitro. We found that TGF-β1 as a local tumor environmental cytokine plays important role in the progression and invasiveness of TNBC cells. NVP-BEZ235 inhibited the enhanced cell viability and CXCR4 expression induced by TGF-β1. In addition, the combined treatment of TNBC cell lines with CAPE and NVP-BEZ235 synergistically inhibited cell growth and reduced CXCR4 expression. Also, treatment of MDA-MB-231 cells with CAPE and NVP-BEZ235 led to decreasing the expression levels of p-FOXO3a in a time-dependent manner. Overall, these results suggest that tumor metastasis and progression in TNBC cells can be effectively reduced through the concurrent use of NVP-BEZ235 and CAPE. This could be of particular interest in assessing the effects of this therapy in the reduction of tumor metastasis and progression in other tumor types.

Abstract
OBJECTIVE Myasthenia gravis (MG) is an autoimmune disease mediated by autoantibodies against the neuromuscular junction. The thymus has an important role in the pathogenesis of MG because most patients have thymic pathology, and thymectomy (TE) can reduce the severity of the disease. METHODS In this study, the frequency of Th17 and Tc17 cells was studied in 12 MG patients (pre-TE and 6 months post-TE) and in 12 healthy controls (HC). RESULTS The frequency of Tc17 cells in the pre-TE patients was significantly higher than in the HC (p < 0.05), and after TE, these cells had significantly decreased compared to before TE (p < 0.05). The frequency of Th17 cells in pre-TE patients was significantly higher than in the HC (p < 0.05), and after TE, these cells had significantly decreased compared to before TE (p < 0.05). CONCLUSION Our findings indicated a possible role of Tc17 and Th17 in MG pathogenesis.

Abstract
Soluble forms of nonclassical human leukocyte antigen (HLA)-G have recently been suggested as immunomodulatory factors in multiple sclerosis (MS). HLA-G inhibits the effecter function of T cells and natural killer (NK) cells. Also regulatory T cells (Treg) are considered as pivotal players in MS pathogenesis. Thus, we aimed to evaluate the presence of HLA-G molecules and Treg cells in Relapsing-Remitting Multiple Sclerosis (RRMS) patients and compare it to healthy controls. Patients with RRMS (n=205, mean age=31.32±8.53) and healthy subjects (n=205, mean age=32.2±7.48) were studied. The patients subgrouped to untreated and treated with Interferon beta. Then sHLA-G levels (sHLA-G1 and sHLA-G5) were measured using ELISA method. Treg (CD4+ CD25+ Foxp3+) cells in patients who had sHLA-G>10 U/ml were characterized by using flow cytometry. Our data showed that there was no significant differences between RRMS patients and healthy controls in sHLA-G concentration (p>0.05). Treg cell frequencies were higher in the patients who had sHLA-G >10 U/ml compared to healthy subjects (p<0.05). Collectively, there was significant correlation between sHLA-G and frequency of Treg cells in treated RRMS patients and healthy individuals. It seems that high level sHLA-G has been instrumental in raising frequency of Treg cells in treated patients and could be associated with remission of MS disease.

Abstract
Pulmonary hypertension has a marked detrimental effect on quality of life and life expectancy. In a mouse model of antigen-induced pulmonary arterial remodeling, we have recently shown that coexposure to urban ambient particulate matter (PM) significantly increased the thickening of the pulmonary arteries and also resulted in significantly increased right ventricular systolic pressures. Here we interrogate the mechanism and show that combined neutralization of interleukin 13 (IL-13) and IL-17A significantly ameliorated the increase in right ventricular systolic pressure, the circumferential muscularization of pulmonary arteries, and the molecular change in the right ventricle. Surprisingly, our data revealed a protective role of IL-17A for the antigen- and PM-induced severe thickening of pulmonary arteries. This protection was due to the inhibition of the effects of IL-13, which drove this response, and the expression of metalloelastase and resistin-like molecule α. However, the latter was redundant for the arterial thickening response. Anti-IL-13 exacerbated airway neutrophilia, which was due to a resulting excess effect of IL-17A, confirming concurrent cross inhibition of IL-13- and IL-17A-dependent responses in the lungs of animals exposed to antigen and PM. Our experiments also identified IL-13/IL-17A-independent molecular reprogramming in the lungs induced by exposure to antigen and PM, which indicates a risk for arterial remodeling and protection from arterial constriction. Our study points to IL-13- and IL-17A-coinduced inflammation as a new template for biomarkers and therapeutic targeting for the management of immune response-induced pulmonary hypertension.

Abstract
Particulates from air pollution are implicated in causing or exacerbating respiratory and systemic cardiovascular diseases and are thought to be among the leading causes of morbidity and mortality. However, the contribution of ambient particulate matter to diseases affecting the pulmonary circulation, the right heart, and especially pulmonary hypertension is much less documented. Our own work and that of other groups has demonstrated that prolonged exposure to antigens via the airways can cause severe pulmonary arterial remodeling. In addition, vascular changes have been well documented in a typical disease of the airways, asthma. These experimental and clinical findings link responses in the airways with responses in the lung's vasculature. It follows that particulate air pollution could cause, or exacerbate, diseases in the pulmonary circulation and associated pulmonary hypertension. This perspective details the literature for support of this concept. Data regarding the health effects of particulate matter from air pollution on the lung's vasculature, with emphasis on the lung's inflammatory responses to particulate matter deposition and pulmonary hypertension, are discussed. A deeper understanding of the health implications of exposure to ambient particulate matter will improve our knowledge of how to improve the management of lung diseases, including diseases of the pulmonary circulation. As man-made ambient particulate air pollution is typically linked to economic growth, a better understanding of the health effects of exposure to particulate air pollution is expected to integrate the global goal of achieving healthy living for all.

Abstract
Incidences of sand storms have increased in recent years and there is evidence that these dusts can move across long distances. Sand dusts have different adverse effects on health, but one of the most important of them is pulmonary disease. After inhalation of dust, many dust particles are moved to the airways. Dust particles can be sensed by airways epithelial cells, activate macrophages, dendritic cells and innate immune cells and then initiate responses in various populations of specific immune cells such as T helper cells subsets (Th1, Th2, Th17), T cytotoxic cells and B cells. Initiation of inflammatory immune responses, activation of immune cells and releases of many cytokines, chemokines and other inflammatory molecules, have variable pathologic affects on lung in different respiratory diseases. Unfortunately control of desert dusts is more difficult than control of air pollution. For prevention and treatment of respiratory diseases that are caused by desert dusts, researchers need well-designed epidemiological studies, combined with analysis of the precise composition of sand dusts, and the precise mechanisms of the immune responses. Recognizing the exact cellular and molecular immune mechanisms would be very useful to find new approaches for treatment of desert dust associated pulmonary diseases.

Abstract
Silymarin, a polyphenolic flavonoid derived from milk thistle (Silybum marianum), is known to have anti-inflammatory, hepatoprotective and anticarcinogenic effects. In this study, the in vitro immunomodulatory effect of silymarin was investigated using human CD4+ T cells. Peripheral blood mononuclear cells (PBMC) from healthy individuals were activated with anti-CD3 (5 μg/ml) plus anti-CD28 (2 μg/ml) and treated with 10, 50 and 100 μM silymarin. Cells were incubated 72 hr for proliferation assay using MTT and for viability analysis using PI staining and flow cytometry. Naive CD4+ T cell was also isolated from PBMC, activated with PHA/anti-CD28 and treated with 100 μM silymarin for 72 hr. MAPKs' activity of cell lysate from activated naive CD4+ T cells was assessed using an ELISA-based MAPKinase activity kit, and Th1/Th2/Th17-related cytokine expression was determined by Multi-analyte ELISA array kit. Results indicated a significant inhibition in proliferation of activated PBMC after 48-hr incubation with 100 μM silymarin without causing cell death. Moreover, MAPKs' activity (ERK1/2 and P38) and Th1-related cytokines (IL-2, TNF-α, IFN-γ) were significantly reduced in silymarin-treated cells compared with control after 72 hr. This study shows that silymarin has the ability to inhibit T cell proliferation and pro-inflammatory cytokine secretion in vitro. Furthermore, silymarin is able to inhibit ERK1/2 and P38 pathway activation in T cells stimulated through TCR engagement, a property that is likely associated with its ability to inhibit T cell proliferation and cytokine secretion. Therefore, silymarin, as an immune-response modifier, might be a valuable drug in therapeutic situations in which immunosuppression is required.

Abstract
Deposition of iron in visceral organs, mainly in the liver, causes tissue damage in β-thalassemia major (β-TM) patients. Keratin 18 (K18) represents one of the major caspase substrates during apoptosis of hepatocytes. To better characterize the hepatic apoptosis and/or necrosis in β-thal patients, the circulating levels of M65 (soluble intact K18) and M30 (the caspases-generated K18 fragment) were measured in 40 β-TM patients and compared with 40 healthy controls. The ratio of M30/M65 (caspase-cleaved to total K18) was also determined in thalassemic and normal subjects. Results of the ELISA assays revealed that the serum levels of hepatocyte death markers, M65 and M30, were significantly increased in β-thal patients compared to healthy controls (p <0.0001). M30 serum levels were also positively correlated with the serum levels of liver transaminases including aspartate aminotransferase (AST) (r = 0.337, p = 0.047) and alanine aminotransferase (ALT) (r =0.391, p = 0.02).

Abstract
Sirtuin1 (SIRT1) is an enzyme that deacetylates histones and several nonhistone proteins including p53 during stress and plays an important role in the survival of tumor cells. Hereby, this study describes the potency of salermide as a SIRT1 inhibitor to induce apoptosis in the MCF-7 and MRC-5 cell lines. MCF7 and MRC-5 cell lines were cultured in RPMI-1640 and treated with or without salermide at concentration of 80.56 μmol/L, based on the half-maximal inhibitory concentration (IC50) index at different times (24, 48 and72 h). The IC50 value was established for the salermide in MCF-7. The percentage of apoptotic cells was measured by flow cytometry. Real-time quantitative RT-PCR was performed to estimate the mRNA expression of sirtuin1 in MCF-7 and MRC-5 with salermide at different times. ELISA and Bradford protein techniques were used to detect endogenous levels of total and acetylated p53 protein generated in MCF-7 and MRC-5 cells. Our findings indicated that salermide can induce apoptosis in MCF-7 significantly more effective than MRC-5 cells. We showed that the expression of SIRT1 was dramatically down-regulated by increasing the time of salermide treatment in MCF-7 but not MRC-5 and that the acetylated and total p53 protein levels were increased more in MCF-7 than MRC-5. Salermide, by decreasing the expression of sirtuin1 gene, can induce acetylation of P53 protein and consequently induce significant cell death in MCF-7 that was well tolerated in MRC-5.

Abstract
OBJECTIVE Thalassemia is one of the most common genetic disorders worldwide. Chronic blood transfusions treat the underlying anemia but may lead to iron toxicity. Effective iron chelation remains one of the main targets of clinical management of thalassemia major. In this study, iron-chelating activity of silymarin, a flavonolignan isolated from silybum marianum, was examined in β-thalassemia major. METHODS Patients were treated with the combination of desferrioxamine and silymarin (Legalon(®) ; n = 49) or desferrioxamine plus placebo (n = 48) for 9 months. The serum levels of ferritin, iron, total iron-binding capacity (TIBC), soluble transferrin receptor, and hepcidin were determined at the baseline and after 9-month therapy. Liver function test was performed before and after treatment in both groups. RESULTS Serum ferritin levels decreased significantly from the beginning to the end of silymarin treatment (3028.8 ± 2002.6 vs. 1972.2 ± 1250.6 ng/mL); however, no significant change in serum ferritin was observed in the patients receiving placebo (2249.0 ± 1304.2 vs. 2015.6 ± 1146.8). Moreover, serum iron and TIBC levels were significantly reduced in silymarin group compared with placebo. Patients on silymarin therapy also exhibited a significant decrease in serum levels of hepcidin and soluble transferrin receptor after 9-month treatment period. A significant improvement in liver function test was observed in silymarin group in comparison with placebo. CONCLUSION This study shows that silymarin is effective at reducing iron overload in patients when used in conjunction with desferrioxamine. Therapeutic effects of silymarin on a background of desferrioxamine suggest the potential effectiveness of silymarin alone in reducing body iron burden.

Abstract
BACKGROUND Characteristics of differentiated osteoblasts from adipose derived stem cells (ADSCs) in compared with isolated osteoblasts from normal bone such as calvaria are unknown. The aim of this study was determination and comparison of phenotypic characterization between differentiated osteoblasts from stem cells and calvaria osteoblasts in vitro. METHODS In this study, mesenchymal stem cells were isolated from adipose tissue of human by enzymatic digestion and were differentiated into osteoblasts using osteogenic medium. Characteristics of these cells at first, second, third and fourth weeks were comprised with calvaria osteoblasts that were isolated from human calvaria by explanation culture method. To screen the characteristics of both calvaria and the differentiated osteoblasts, we used western blot to identify protein levels, von Kossa staining for mineral matrix detection and alkaline phosphatase (ALP) assay kit (Sigma) for ALP activity measurement. Difference between calvaria and differentiated osteoblast cells were analyzed by one-way ANOVA and P < 0.05 was considered as statistically significant. RESULTS Alkaline phosphatase activity, collagen and mineral material production in differentiated osteoblasts at third week were more significantly than calvaria cells (P < 0.05). Our results indicated that there was no significant different in osteocalcin (OC) production between differentiated osteoblast at first, second and third weeks and calvaria cells but declined at fourth week (P < 0.05). CONCLUSIONS Our survey showed that cellular traits of differentiated osteoblasts presented better than calvaria osteoblasts in vitro conditions. Therefore, we suggest that ADSCs could be used in next studies for bone tissue engineering.

Abstract
Background Atherosclerosis which results from gradual deposition of lipids in medium and large arteries is a leading cause of mortality worldwide. The objective of this study was to determine the effect of apple juice on some risk factors of atherosclerosis and on the development of atherosclerosis in rabbits fed a high-cholesterol diet. Methods Thirty two male rabbits were randomly divided into four groups: normal diet, high cholesterol diet (%1 cholesterol), 1% cholesterol supplemented with 5 ml apple juice (low dose) and 1% cholesterol supplemented with 10 ml apple juice (high dose) for 2 month. The C-reactive protein (CRP), nitrite, nitrate, fibrinogen, total cholesterol(TC) and factor VII were measured before the experiment and by the end of period. At the end of study, fatty streak formation in right and left coronary arteries were determined using Chekanov method in all groups. Results Both doses of apple juice significantly were decreased TC, TG, CRP, fibrinogen, factor VII levels, atherosclerotic lesion in right and left coronary arteries and increased nitrite and nitrate compared to cholesterolemic diet. Also using 10 ml apple juice caused significant reduce in LDL-C and increase HDL-C, but 5 ml apple juice did not change these factors. Significant differences were observed between 5 and 10 ml apple juice groups by LDL-C. No significant difference was found between 5 and 10 ml apple juice groups with regard to CRP, nitrite, nitrate, fibrinogen, factor VII, TG, HDL-C and TC concentrations. Conclusion Apple juice can effectively prevent the progress of atherosclerosis. This is likely due to antioxidant and anti-inflammatory effect of apple juice.
