Abstract
Neutrophil-lymphocyte (NLR), platelet-lymphocyte (PLR), eosinophil-lymphocyte (ELR), and monocyte-lymphocyte (MLR) ratios are systemic inflammatory markers related to myocardial infarction. The aim of this study is to investigate the association of Src homology 2-B adapter protein 3 (SH2B3) C784 T and methylenetetrahydrofolate reductase (MTHFR) C677 T polymorphisms (SNP) with systemic inflammatory markers and the severity of coronary artery disease (CAD) in 150 ST-elevation myocardial infarction (STEMI) patients. Single nucleotide polymorphisms were genotyped using the tetra-primer amplification refractory mutation system-polymerase chain reaction (T-ARMS-PCR) method. The inflammatory markers were calculated. An interventional cardiologist blinded to other data assessed the SYNTAX (SX) Score. Eosinophil and platelet counts were significantly higher in SH2B3 variants than in the wild type. Additionally, SH2B3 variants had significantly higher ELR than the wild type (.12 ± .19 vs .25 ± .34, p = .018). NLR, PLR, ELR, and MLR were considerably higher in MTHFR variants than in the wild type (p < .05). The SX score was significantly higher in both SH2B3 C784 T (21.24 ± 8.90 vs 15.29 ± 9.40, p = .00) and MTHFR C677 T (20.34 ± 10.21 vs 16.08 ± 8.39, p = .00) variants when compared with wild type. In conclusion, these polymorphisms are associated with several markers of systemic inflammation as well as the severity of CAD.

Abstract
BACKGROUND Imatinib resistance remains a major obstacle in the treatment of chronic myelogenous leukemia (CML). Crocin (CRC) and astaxanthin (ATX) are phytochemicals with anti-cancer properties. AIMS This study aimed to explore the effects of combination treatment of Imatinib with CRC and ATX on Imatinib-resistant K562 (IR-K562) cells. METHODS AND RESULTS After the establishment of IR-K562 cells, growth inhibitory activity was determined by the MTT assay. To test the regeneration potential, a colony formation assay was performed. Cell cycle analyses were examined by flow cytometry. Cell injury was evaluated by lactate dehydrogenase (LDH) leakage. Real-time PCR was applied to assess the expression of IL6, TNF-α, STAT3, BAD, CASP3, TP53, and Bcl-2 genes. Caspase-3 activity was determined by a colorimetric assay. Antioxidant activity was measured using a diphenylpicrylhydrazyl (DPPH) assay. After 48 h of treatment, ATX (IC50 = 30µM) and CRC (IC50 = 190µM) significantly inhibited cell proliferation and colony formation ability, induced G1 cell cycle arrest and cell injury, upregulated the expression of apoptosis-associated genes, and downregulated the expression of anti-apoptotic and inflammatory genes. The combination of IM with ATX and/or CRC synergistically reduced cell viability (combination index [CI] < 1). CONCLUSION Our data suggest that IM shows better therapeutic efficacy at lower doses when combined with ATX and/or CRC.

Abstract
Background Diabetic retinopathy (DR) is expanding to epidemic levels globally due to the progressing prevalence of diabetes mellitus (DM). In this study, the association between factor V Leiden (FVL), MTHFRC677T, and FXIIIVal34Leu polymorphisms and diabetic retinopathy was investigated in Eastern Iran. Methods This case-control study enlisted the participation of 300 people (diabetic patients=100, diabetic retinopathy patients=100, healthy controls=100), and polymorphisms were examined by Tetra primer ARMS-PCR. Results The frequency of FVL (p=0.294) and FXIIIVal34Leu (P=0.349) polymorphism showed no significant results between the genotype frequency in the mentioned groups. In contrast, MTHFRC677T SNP was significantly different in diabetic patients and controls (P=0.008). The MTHFRC677T polymorphism was found to be connected with increased systolic blood pressure in patients who had the TT genotype (130.96±11.92mm/Hg; P=0.011). Conclusion Our study recommended that the MTHFRC677T polymorphism may offer to DR development. Studies with larger sample sizes and a wider spectrum of populations are authorized to verify this finding.

Abstract
Immunotherapy is changing the Head and Neck Squamous Cell Carcinoma (HNSCC) landscape and improving outcomes for patients with recurrent or metastatic HNSCC. A deeper understanding of the tumor microenvironment (TME) is required in light of the limitations of patients' responses to immunotherapy. Here, we aimed to examine how Nivolumab affects infiltrating Tregs in the HNSCC TME. We used single-cell RNA sequencing data from eight tissues isolated from four HNSCC donors before and after Nivolumab treatment. Interestingly, the study found that Treg counts and suppressive activity increased following Nivolumab therapy. We also discovered that changes in the CD44-SSP1 axis, NKG2C/D-HLA-E axis, and KRAS signaling may have contributed to the increase in Treg numbers. Furthermore, our study suggests that decreasing the activity of the KRAS and Notch signaling pathways, and increasing FOXP3, CTLA-4, LAG-3, and GZMA expression, may be mechanisms that enhance the killing and suppressive capacity of Tregs. Additionally, the result of pseudo-temporal analysis of the HNSCC TME indicated that after Nivolumab therapy, the expression of certain inhibitory immune checkpoints including TIGIT, ENTPD1, and CD276 and LY9, were decreased in Tregs, while LAG-3 showed an increased expression level. The study also found that Tregs had a dense communication network with cluster two, and that certain ligand-receptor pairs, including SPP1/CD44, HLA-E/KLRC2, HLA-E/KLRK1, ANXA1/FPR3, and CXCL9/FCGR2A, had notable changes after the therapy. These changes in gene expression and cell interactions may have implications for the role of Tregs in the TME and in response to Nivolumab therapy.

Abstract
BACKGROUND There is a strong association between hyperglycemia, oxidative stress, inflammation and the onset and progression of diabetes which causes a higher risk of cancer. This study investigated, the effect of concomitant use of omega-3 polyunsaturated fatty acids (ω-3 PUFAs) with iron supplements in hyper-glucose conditions on the K-562 cell line. METHODS The effects of iron, ω-3 PUFAs, and a combination of both on K-562 cells were investigated under normal and high glucose conditions. The impact of these treatments was evaluated using multiple methodologies, including the MTT assay for cell viability, quantification of oxidative stress markers [total antioxidant capacity (TAC) and malondialdehyde (MDA)], and analysis of the cell cycle. Furthermore, the expression levels of TNFα and p53 mRNA were measured using Real-time PCR. RESULTS The co-treatment of ω-3 PUFAs and iron in the presence of high glucose had notable effects, as evidenced by an increase in cell survival, resistance to imatinib chemotherapy, TNFαmRNA expression levels, MDA levels, and percentage of cells in the G2/S phase. Additionally, there was a decrease in the mRNA expression of p53 and TAC levels compared to treatment in the normal-glucose condition. CONCLUSION Hyperglycemic conditions in conjunction with the combined treatment of theω-3 PUFAs and iron, led to reduced anticancer capacity, chemosensitivity, anti-inflammatory and antioxidant properties of the K-562 cells. These effects were found to be mediated by oxidative stress.

Abstract
Background
Acute myocardial infarction (AMI) is a leading cause of death and morbidity around the world. Although the association between thrombophilia and AMI is well-established, controversial data are present on the association between thrombophilic polymorphisms and AMI. The aim of this study was to investigate the association of three thrombophilic polymorphisms including factor V Leiden (FVL), MTHFRC677T (methylenetetrahydrofolate reductase), and Coagulation factor XIIIVal34Leu with AMI in East of Iran.
Result
There were no statistically significant differences between the patients and control groups in terms of the distributions of allelic and genotypic frequencies of FVL and FXIIIVal34Leu polymorphisms (P-value > 0.05). Subjects who carried CT genotype of MTHFR C677T polymorphism were at a 2.03-fold higher risk for AMI (P-value: 0.02, OR 1.76, 95% CI 1.07–2.75). Furthermore, patients with MTHFR 677CT (P-value < 0.001, β = - 0.90, 95% CI − 1.33, − 047) or 677CC (P-value < 0.001, β = - 1.04, 95% CI − 1.47, − 0.61) genotypes showed significantly Lower creatinine levels compared with patients having the MTHFR 677TT. No association was observed between the other remaining polymorphisms and AMI (P-value > 0.05).
Conclusion
Our findings showed that MTHFRC677T polymorphism could contribute to AMI susceptibility and increase creatinine levels in east Iran population. This was the first study to examine the association of these three polymorphisms with AMI in east Iran.

Abstract
Recently, the development and application of fungal exopolysaccharides (EPS) as natural biopolymers are on the rise. The present study is based on the investigation of possible antiproliferative and antioxidant activities of EPS from the Rhodotorula mucilaginosa sp. GUMS16 on BCR-ABL positive cells (K562). The cytotoxicity, colony formation assays lactate and dehydrogenase (LDH) activity were performed to assess the possible cancer cell death. To elucidate the underlying antiproliferative mechanism of the EPS, cell cycle analysis following real-time PCR (gene expression assessment) were evaluated. The results indicated that, the EPS with an IC50 dose of 1500 μg/ml, reduced the viability of K562 cells without having toxic effects on normal cells as well as decrease in size and number of colonies in EPS-treated group (p < 0.0001). The increase of LDH was 2.75 times more than the control (p < 0.0001). Gene expression revealed up- and down-regulation of apoptotic and anti-apoptotic genes in EPS group compared with the control. Moreover, the DPPH scavenging activity of the EPS in treated cells was significantly higher than the control group (p < 0.0001). Taken together, we concluded that the EPS from GUMS16 strain is able to inhibit the growth of K562 cells besides having antioxidant activities.

Abstract
BACKGROUND: Confidential unit exclusion (CUE) was recommended by the Food and Drug Administration to permit blood donors confidentially exclude their donation for transfusion. However, its effectiveness as a safety measure to the blood supply is debated. AIMS: We, therefore, evaluated its benefit in identifying donors at risk of transmitting transfusion-transmissible infections (TTIs) and increasing blood safety in our population. SETTINGS AND DESIGN: This was a cross-sectional and retrospective study. The study was performed at the South Khorasan Blood Transfusion Center. MATERIALS AND METHODS: In this descriptive and retrospective study, data of CUE use and data of confirmed positive TTI markers were analyzed for the study period 2006–2016. STATISTICAL ANALYSIS: Data were analyzed using SPSS software version 16. RESULTS: Out of 165,267 donations, the CUE option was selected by 493 (0.3%) donors, most frequently by first-time blood donors, by men, by donors with <12 years schooling, and by 18–24-year-old donors. The data revealed that donations from CUE donors had no higher infection rates. Moreover, CUE showed low sensitivity (0.6%) and low positive predictive value (0.6%) in detecting TTI markers. CONCLUSION: The data do not provide any indication of a safety advantage from CUE; thus, we recommend that the procedure of CUE can be discontinued.

Abstract
A copper complex supported on SBA-15 nanoparticles (Cu/TCH-pr@SBA-15) was synthesized by the post-synthesis modification of nano-mesoporous silica with 3-chloropropyltriethoxysilane (CPTES) and thiocarbohydrazide (TCH) and subsequent metal–ligand coordination with Cu(ii). These nanocomposites were thoroughly characterized by FT-IR spectroscopy, TEM, FE-SEM, EDX, atomic absorption spectroscopy and N2 adsorption–desorption (BET) studies. Then, a solvent-free method was developed for the three-component synthesis of 4-arylidene-isoxazolidinones via condensation of hydroxylamine hydrochloride, ethyl acetoacetate and various aromatic aldehydes using Cu/TCH-pr@SBA-15 as a highly efficient nanocatalyst. This new economic and eco-friendly methodology has remarkable advantages such as excellent yields, a shorter reaction time, an easy purification procedure, simplicity, green conditions, solvent-free conditions, and recoverability of the nanocatalyst. A copper complex supported on SBA-15 nanoparticles (Cu/TCH-pr@SBA-15) was synthesized by the post-synthesis modification of mesoporous silica with (OEt)3Si-(CH2)3Cl and thiocarbohydrazide (TCH) and subsequent metal–ligand coordination with Cu(ii).![]()

Abstract
BACKGROUND Confidential unit exclusion (CUE) is a mechanism developed in the1980s to increase blood safety by allowing donors to indicate confidentially if they think their blood is not safe for transfusion. While it has been used widely around the world, the efficacy of this strategy is still unclear. The present study evaluated the efficacy of the CUE system at the Blood Transfusion Center of Kohgiluyeh and Boyer Ahmad Province (KBTC), Iran by comparing the prevalence of transfusion-transmitted infectious (TTIs) in CUE and non-CUE groups. METHODS This descriptive study used data from all volunteer blood donors over a ten-year period. Donors were classified in two groups: CUE and non-CUE. Screening tests were performed for hepatitis B surface antigens (HBs-Ag), hepatitis C virus antibody (HCV-Ab), and Human immunodeficiency virus antibody (HIV-Ab) and any repeatedly reactive results were confirmed by standard methods. Significant differences were determined by Chi2 test. The sensitivity, specificity and PPV of the CUE system were also calculated. RESULTS In the present study, the non-CUE and CUE groups consisted of 98.94% and 1.06% of volunteer blood donors, respectively. First-time donors selected the CUE option more often than repeated and regular donors. The prevalence of TTIs was significantly higher in the CUE group and CUE sensitivity, specificity, and PPV were 5.5%, 98.95%, and 0.96%, respectively. CONCLUSION We recommend the CUE system be pursued for further enhancement of blood safety. However, further studies are needed to establish the overall usefulness of this procedure throughout the whole country.

Abstract
The secretory production of heterologous proteins in E. coli has revolutionized biotechnology. Efficient periplasmic production of foreign proteins in E. coli often requires a signal peptide to direct proteins to the periplasm. However, the presence of attached signal peptide does not guarantee periplasmic expression of target proteins. Overproduction of auxiliary proteins, such as chaperones can be a useful approach to enhance protein export. In the current study, three chaperone plasmid sets, including GroEL-GroES (GroELS), Dnak-Dnaj-GrpE (DnaKJE), and trigger factor (TF), were coexpressed in E. coli BL21 (DE3) in a pairwise manner with two pET22-b vectors carrying the recombinant hirudin-PA (Hir) gene and different signal sequences alkaline phosphatase (PhoA) and l-asparaginase II (l-ASP). Overexpression of cytoplasmic combinations of molecular chaperones containing GroELS and DnaKJE with PhoAHir increased the secretory production of PhoAHir by 2.6fold (p < 0.05) and 3.5fold (p < 0.01) compared with their controls, respectively. By contrast, secretory production of PhoAHir significantly reduced in the presence of overexpressed TF (p = 0.02). Further, periplasmic expression of l-ASP was significantly increased only in the presence of DnaKJE (p = 0.04). These findings suggest that using molecular chaperones can be helpful for improving periplasmic expression of Hir. However, tagged signal peptides may affect the physicochemical properties and secondary and tertiary structures of mature Hir, which may alter their interactions with chaperones. Hence, using overexpressed chaperones has various effects on secretory production of PhoAHir and l-ASPHir.

Abstract
Background: The conventional chemotherapeutic regimens which applied for treatment of acute myeloid leukemia (AML) mostly target tumor bulk but not leukemic stem cells (LSCs). Aberrant expression or activation of mediators such as osteopontin (OPN) or PI3K/PTEN/Akt/mTOR pathway plays a key role in making prone to develop leukemia. Preventing or treating cancer by curcumin (CUR) has been suggested recently. CUR induces apoptosis and growth inhibition through various mechanisms in leukemic cells. In present study, we tried to measure the toxic response in vitro to CUR for evaluation ofchangesin cell viability, survival and molecular-mediated resistance in primary AML cells. Materials and Methods: Isolated primary CD34+/CD38- bone marrow derived AML cells were treated with CUR, Daunorubicin (DNR) and/or their combination by MTT assay, Annexin V/PI staining, and colony-formation. The mRNA expression of OPN/AKT/mTOR/PTEN/β-catenin genes was measured by Real-Time PCR. The siRNA against OPN was applied for CUR- treated cells. Results: Growth inhibition effect of DNR increased in combination with CUR on primary CD34+/CD38- AML cells. Suppression of OPN with siRNA increased the cytotoxic effects of CUR. Likewise, OPN gene expression increased in response to CUR treatment in AML cells. AKT, mTOR, β-catenin or PTEN gene expression increased by CUR, but OPN siRNA decreased the level of mRNA expression of mentioned molecular pathway. Conclusion: The chemo-resistance of AML cells against therapy might be relevant to increasing of OPN mRNA expression and activity of other mediators including AKT, mTOR, PTEN, and β-catenin. In this context, targeting of OPN might be more impact on CD34+ AML cells.

Abstract
Hirudin is an anticoagulant agent of the salivary glands of the medicinal leech. Recombinant hirudin (r-Hir) displays certain drawbacks including bleeding and immunogenicity. To solve these problems, cysteine-specific PEGylation has been proposed as a successful technique. However, proper selection of the appropriate cysteine residue for substitution is a critical step. This study has, for the first time, used a computational approach aimed at identifying a single potential PEGylation site for replacement by cysteine residue in the hirudin variant 3 (HV3). Homology modeling (HM) was performed using MODELLER. All non-cysteine residues of the HV3 were replaced with the cysteine. The best model was selected based on the results of discrete optimized protein energy score, PROCHECK software, and Verify3D. The receptor binding was investigated using protein-protein docking by ClusPro web tool which was then visualized using LigPlot+ software and PyMOL. Finally, multiple sequence alignment (MSA) using ClustalW software and disulfide bond prediction were performed. According to the results of HM and docking, Q33C, which was located on the surface of the protein, was the best site for PEGylation. Furthermore, MSA showed that Q33 was not a conserved residue and LigPlot+ software showed that it is not involved in the hirudin-thrombin binding pocket. Moreover, prediction softwares established that it is not involved in disulfide bond formation. In this study, for the first time, the utility of the in silico approach for creating a cysteine analogue of HV3 was introduced. Our study demonstrated that the substitution of Q33 by cysteine probably has no effect on the biological activity of the HV3. However, experimental analyses are required to confirm the results.

Abstract
A predominant challenge in developing curative leukemia therapy is interactions of leukemic cells with the bone marrow stromal microenvironment. We aimed to investigate the role of stromal cells, such as bone marrow mesenchymal stromal cells (BMSCs) and osteoblasts (OBs), in curcumin (CUR) and daunorubicin (DNR) induced apoptosis of acute myeloid leukemia (AML) cells. We used KG1 and U937 as leukemia cell line models and treated them with CUR and DNR. The cells were then co-cultured with BMSCs or a combination of BMSCs and OBs as feeders. After 24 hours of co-culture, BMSCs or OBs were sorted and separated from the leukemia cells and apoptosis levels were analyzed by annexin/propidium iodide (PI) staining on flow cytometry. Potentially involved molecular pathways were analyzed at gene and protein levels by Real time PCR and western blotting, respectively. The results showed AML cells co-cultured with BMSCs plus OBs to be more resistant to drug induced-apoptosis compared to co-culture with BMSCs alone or without co-culture. Expression levels of OPN, CXCL-12, IL-6, STAT-3 and VCAM-1 were also significantly up-regulated in OBs and AML cells, at both mRNA and protein levels after co-culture, with concurrent enrichment of CD34+ AML cells. Our data showed, in a stromal cell niche-based model, that OBs revoke the influence of BMSCs on leukemic cells and promote enrichment of both CD34+ and CD34- leukemic stem cell (LSC) compartments in response to CUR and DNR. Up-regulation of OPN, CXCL-12, IL-6, STAT-3 and VCAM-1 in OBs and AML cells in co-culture might be part of molecular mechanisms that block CUR or CUR+DNR-induced apoptosis and promote enrichment of CD34+ and CD34- LSCs.

Abstract
As one of the induced pluripotent stem cells (iPSCs) methods, spermatogonial stem cells (SSCS ) extract is considered as new approach in stem cell therapy of infertility. 5-aza-2'-deoxycytidine (5-aza-dC) inhibits methyltransferase enzyme, and induces gene reprogramming; herein, the effects of SSCS extract incubation in 5-aza-dC-treated bone marrow mesenchymal stem cells (BMMSCs) has been surveyed. BMMSCs were isolated from femurs of three to four weeks old male NMRI mice, and the cells at passage three were treated with 2 µM 5-aza-dC for 72 hours. SSCs were isolated, cultured, and harvested at passage three to collect SSCS extract; BMMSCs were then incubated with SSCS extract in the three time periods: 72 hours, one week and two weeks. There were five groups: control, sham, extract, 5-aza-dC and extract-5-aza-dC. After one week of incubation, flow cytometry and real-time polymerase chain reaction (PCR) exhibited high levels of expression for β1- and α6-integrins and promyelocytic leukaemia zinc finger (PLZF) in extract and extract-5-aza-dC groups (P < 0.05 vs. control and 5-aza-dC), and cells in these two groups had two forms of morphology, round and fusiform, similar to germ-like cells. 5-aza-dC had no significant effects during the three time periods of evaluation. These data disclose the effectiveness of SSCs extract incubation in transdifferentiation of BMMSCs into germ-like cells; this strategy could introduce a new approach for treatment of male infertility in clinic.

Abstract
A two-way soft resolution method will fail when applied to a simultaneous equilibria system due to rank deficiency in its concentration profiles. Increasing the dimensionality of measurements from two-way to three-way data can be used to overcome this problem. Simultaneous dissociation of two weak acids is considered as a model for simultaneous equilibria. Three-way data obtained from excitation-emission spectrofluorimetric monitoring of a pH-metric titration is analyzed using a proper combination of well-known soft-modeling methods. Multivariate curve resolution-alternating least squares is used for calculating the excitation and emission spectral profiles of involved species and rank annihilation factor analysis for obtaining the contribution of each species in measured excitation-emission matrices at different pHs. The results of simulated and real simultaneous acids dissociation equilibria showed that the proposed combined method performs well even in situation when the equilibrium constants are close to each other. The applicability of method for study of an acidic dissociation is also shown.
