Abstract
Background Recurrent abortion refers to a condition of two or more consecutive pregnancies without known etiology affected by miscarriage before the completion of the 20th week of gestational age. However, several hypotheses have been proposed, but not much data are available concerning the relationship between human platelet antigens (HPAs) polymorphisms and recurrent abortion. This study was conducted to evaluate the genetic differences between HPA-1, -2, -3, -5, and - 15 in Iranian couples with a history of recurrent abortion. Methods In this cross-sectional study, a total of 74 couples with at least 2 recurrent abortions without any known specified reasons enrolled in the study. HPA polymorphisms genotyping was performed by single-specific primer PCR. Genotype frequency was calculated using the Hardy-Weinberg equation. Results A total of 39 couples (52.7%) had HPA genotyping partial mismatches. The most common partial mismatch pairs were found concomitantly on both HPA-15a and HPA-15b in three couples (4%), followed by two (2.7%) on HPA-3a and one (1.3%) in each HPA-2b and HPA-5b. There was a deviation from the Hardy-Weinberg equilibrium in the HPA-2 and -5 systems. Conclusion The present study declared that partial mismatches of HPA-3 and -15 genotypes were common among Iranian couples due to the history of recurrent abortion and approximately half of the couples carried at least one HPA gene that was absent in their partners. Further studies might be helpful to clarify the association between HPA polymorphisms and recurrent abortion, such as an investigation into the alloantibodies against HPAs.

Abstract
BACKGROUND AND OBJECTIVES Platelet storage lesion (PSL) adversely affects the quality of platelet concentrates (PCs). Platelets are prone to activation during storage. Moreover, elevated free mitochondrial DNA (mtDNA) levels in PCs are associated with a higher risk of adverse transfusion reactions. Therefore, we aimed to evaluate the correlation between platelet activation markers and mtDNA release during PC storage. MATERIALS AND METHODS Six PCs prepared by the platelet-rich plasma method were assessed for free mtDNA copy number using quantitative real-time PCR and CD62P (P-selectin) expression by flow cytometry on days 0 (PC collection day), 3, 5 and 7 of storage. Lactate dehydrogenase (LDH) activity, pH, platelet count, mean platelet volume (MPV) and platelet distribution width (PDW) were measured as well. The correlation between free mtDNA and other PSL parameters, and the correlation between all parameters, was determined. RESULTS Significant increases in free mtDNA, MPV and PDW, and a significant decrease in platelet count and pH were observed. CD62P expression and LDH activity elevated significantly, particularly on storage days 5-7 and 0-3, respectively. Moreover, a moderate positive correlation (r = 0.61) was observed between free mtDNA and CD62P expression. The r values between free mtDNA and LDH, pH, platelet count, MPV and PDW were 0.81, -0.72, -0.49, 0.81 and 0.77, respectively. CONCLUSION The interplay between platelet activation and mtDNA release in promoting PSL in PCs may serve as a promising target for future research on applying additive solutions and evaluating the quality of PCs to improve transfusion and clinical outcomes.

Abstract
T helper 1 (TH1) and TH2 lymphocytes are the most important components of the immune system affected by blood transfusion. This study aimed`` to evaluate the effect of blood transfusion on gene expression of transcription factors related to the development of TH1, TH2, TH17 and regulatory T cells (Tregs). In this cross-sectional study, 20 patients diagnosed with abdominal aortic aneurysms requiring surgical repair were studied from January 2018 to August 2020. We utilized real-time PCR to evaluate the expression of transcription factor genes associated with TH1, TH2, TH17, and Treg, namely T-box-expressed-in-T-cells (T-bet), GATA-binding protein 3 (GATA-3), retinoid-related orphan receptor (RORγt), and fork head box protein 3 (Foxp3), respectively. The sampling occurred before anesthesia, 24- and 72 hours post-transfusion, and at the time of discharge. The results showed that the T-bet gene expression, compared to the time before transfusion, was significantly decreased 24 hours after blood transfusion and upon discharge while GATA3 genes exhibited a significant reduction both 24 and 72 hours after the transfusion, as compared to the pre-transfusion levels and the time of patient discharge. The Foxp3 gene demonstrated an increase at all study stages, with a notable surge, particularly 72 hours after red blood cell (RBC) transfusion. Conversely, the expression of RORγt gene, consistently decreased throughout all stages of the study. RBC transfusion in abdominal aortic aneurysm patients altered the balance of transcription gene expression of TH1, TH2, TH17, and Treg cells.

Abstract
Human Parvovirus 4 (PARV4) is an emerging virus infecting individuals with other blood-borne diseases. This study aimed to determine the prevalence of PARV4 in confirmed HTLVI/II positive samples from blood donors, assessing PARV4 viral load (DNA) and genotyping. METHODS A novel qReal-Time PCR, based on a plasmid construct, was developed to simultaneously detect all three PARV4 genotypes using in-house primers and probes. Positive qPCR samples were subjected to nested PCR amplification and subsequent sequencing. Phylogenetic trees were constructed using the Neighbor-joining (N.J.) method. RESULTS The coinfection rate of PARV4-DNA in HTLVI/II confirmed infected donors, who were previously deferred, was 14.4 % (13 out of 90), with no observed association with donation status (p = 1.0). Phylogenetic analysis indicated that PARV4-positive samples closely resembled genotype 2 in Iran.qPCR quantification demonstrated significant PARV4 viral loads in positive samples, ranging between 104 and 106 DNA copies/mL of serum. CONCLUSION This study presents the first evaluation of HTLVI/II and PARV4coinfection rates among blood donors. Notably, elevated PARV4-DNA titers were detected in HTLVI/II-positive donors. Given PARV's resistance to standard plasma refinery inactivation methods and the absence of its targeted inactivation, its potential impact remains a concern.

Abstract
Platelet activation and mitochondrial damage are among the crucial events leading to the quality reduction of platelet concentrates (PCs) during preparation and storage, called platelet storage lesion. Platelet activation results in the clearance of transfused platelets. Oxidative stress and platelet activation trigger mitochondrial DNA (mtDNA) release into the extracellular milieu which is associated with adverse transfusion reactions. Therefore, we aimed to investigate the effects of resveratrol, an antioxidant polyphenol, on platelet activation markers and mtDNA release. Ten PCs were divided equally into two bags each, one of them was allocated to the control group (n = 10) and another to the case group (resveratrol-treated, n = 10). Free mtDNA level and CD62P (P-selectin) expression level were measured by absolute quantification Real-Time PCR, and flow cytometry on days 0 (the receiving day), 3, 5, and 7 of storage respectively. Moreover, Lactate dehydrogenase (LDH) enzyme activity, pH, platelet count, mean platelet volume (MPV), and platelet distribution width (PDW) were assessed as well. Treatment of PCs with resveratrol can significantly decrease mtDNA release during storage compared to the control. In addition, platelet activation was significantly mitigated. We also observed significantly lower MPV, PDW, and LDH activity in resveratrol-treated PCs compared to the control group on days 3, 5, and 7. Furthermore, resveratrol maintained the pH of PCs on day 7. Resveratrol diminished free mtDNA and maintained biochemical parameters in PCs, possibly by reducing platelet activation. Therefore, resveratrol might be a possible additive solution for improving the quality of stored PCs.

Abstract
miR-183/96/182 cluster plays a critical role in the developing retina by regulating many target genes involved in signaling pathways. This study aimed to survey the miR-183/96/182 cluster-target interactions that, potentially contribute to human retinal pigmented epithelial (hRPE) cell differentiation into photoreceptors. Target genes of the miR-183/96/182 cluster were obtained from miRNA-target databases and applied to construct miRNA-target networks. Gene ontology and KEGG pathway analysis was performed. miR-183/96/182 cluster sequence was cloned into an eGFP-intron splicing cassette in an AAV2 vector and overexpressed in hRPE cells. The expression level of target genes including HES1, PAX6, SOX2, CCNJ, and RORΒ was evaluated using qPCR. Our results showed that miR-183, miR-96, and miR-182 share 136 target genes that are involved in cell proliferation pathways such as PI3K/AKT and MAPK pathway. qPCR data indicated a 22-, 7-, and 4-fold overexpression of miR-183, miR-96, and miR-182, respectively, in infected hRPE cells. Consequently, the downregulation of several key targets such as PAX6, CCND2, CDK5R1, and CCNJ and upregulation of a few retina-specific neural markers such as Rhodopsin, red opsin, and CRX was detected. Our findings suggest that the miR-183/96/182 cluster may induce hRPE transdifferentiation by targeting key genes that involve in the cell cycle and proliferation pathways.

Abstract
BACKGROUND To study the clinical utility of broad-range real-time Polymerase Chain Reaction (PCR) assay in patients suspected for infectious uveitis and to analyze the clinical relevance. METHODS Medical records of patients with uveitis were assessed in whom PCR analysis of intraocular fluids was performed between January 2018 and February 2021. Intraocular samples were investigated for cytomegalovirus (CMV), Epstein-Barr virus (EBV), varicella zoster virus (VZV), herpes simplex viruses type 1 and 2 (HSV1,2), human T-lymphotropic virus type 1 (HTLV-1), Toxoplasma gondii and also for bacterial 16 S and fungal 18 S/28S ribosomal DNA (rDNA). RESULTS Aqueous paracentesis and vitreous sampling was done for 151 (81.2%) and 35 (18.8%) patients, respectively. Most of the patients had panuveitis (61.3%). PCR results were positive in 69 out of 186 patients (37%) according to the following order: CMV (18 cases), VZV (18 cases), fungal 18s/28s rDNA (17 cases), HSV (9 cases), bacterial 16s rDNA (3 cases), HTLV-1 (2 cases), and Toxoplasma gondii (2 cases). PCR positivity rate was 5.8% in patients with undifferentiated panuveitis. EBV was not detected at all. Initial treatment was changed in 38 patients (20%) based on PCR results. The overall sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of PCR test for aqueous samples was 82%, 91%, 96%, and 87%, respectively. No significant adverse effect related to sampling was reported. CONCLUSION PCR analysis of intraocular fluids in patients with suspected infectious uveitis plays an important role in confirming diagnosis or changing treatment with good predictive value. However, routine PCR test in patients with undifferentiated panuveitis in order to rule out possible underlying infectious etiology had low benefit.

Abstract
Oxidative stress and mitochondrial damage are causes of platelet storage lesions (PSLs). Mitochondrial damage causes mitochondrial DNA (mtDNA) to be released into the extracellular space. MtDNA in platelet concentrates is considered damage-associated molecular patterns (DAMPs) and is one of the major causes of PSLs. The mechanism of mtDNA release in platelet concentrates has not been thoroughly investigated. This study aimed to determine the effect of reactive oxygen species (ROS) on mtDNA release in platelet concentrates during storage. Ten platelet concentrates from healthy donors were obtained in this investigation. Platelet concentrates were prepared by platelet-rich plasma (PRP) and stored at 22 ± 2 C° with gentle agitation. Platelet concentrates were subjected to flow cytometry and real-time PCR to evaluate total ROS and free mtDNA on days 0, 3, and 5 of platelet concentrate storage. Total ROS detected significantly increased from day 0 to day 5 of platelet concentrate storage (P = 0.0079). The mean of copy numbers of free mtDNA on day 0 increased from 3.43 × 106 ± 1.57 × 106 to 2.85 × 107 ± 1.51 × 107 (molecules/μl) on the fifth day of platelet concentrate storage, and it was statistically significant (P = 0.0039). In addition, LDH enzyme activity significantly increased during platelet concentrate storage (P < 0.0001). Also, releasing mtDNA in platelet concentrates was directly correlated with total ROS generation (P = 0.021, r = 0.61) and LDH activity (P = 0.04, r = 0.44). The evidence from this study confirmed the increasing level mtDNA copy numbers in platelet concentrates during storage, and the amount of free mtDNA is directly correlated with ROS generation and platelet lysis during 5 days of platelet concentrate storage. Finally, these changes may be related to DAMPs in the platelet concentrates.

Abstract
Background Due to the presence of platelet antigen polymorphisms, human platelet membrane glycoproteins can be identified as an alloantigen or autoantigen. The aim of this study was to determine the frequencies of human platelet antigens (HPAs)-1 to-5 and-15 in Turkmen blood donors and establish a panel of accredited HPAs negative donors as well as an HPA-typed platelet donor registry. Materials and Methods HPA-1 to-5 and-15 typing was performed by the polymerase chain reaction-sequence-specific primer techniques on 80 unrelated Turkmen donors who were referred to Aq-Qala Blood Transfusion Center in Golestan Province from September 2018 to October 2019. Results The frequencies of HPA phenotypes were determined as follows: HPA-1aa: 92.5%, HPA-1ab: 7.5%, HPA-2aa: 77.5%, HPA-2ab: 20.0%, HPA-2bb: 2.5%, HPA-3aa: 75.3%, HPA-3ab: 50%, HPA-3bb: 11.2%, HPA-4aa: 100%, HPA-5aa: 78.5%, HPA-5ab: 21.5%, HPA-15aa: 41.2%, HPA-15ab: 56.2% and HPA-15bb: 17.5%. Conclusion Determining the genotype of HPAs that play an important role in platelet refractory can improve the management of alloimmunization due to the incompatibility of HPAs between the recipients and donors. Therefore, the registration process for national platelet donors can help patients accelerate and improve the quality of transfused platelets.

Abstract
Platelet storage lesions may occur in Platelet concentrates (PCs) storage time, reducing PCs' quality. Mitochondrial damage causes mitochondrial DNA (mtDNA) to be released into the extracellular space. In this study, we evaluated the effect of L-carnitine (LC) as an antioxidant on free mtDNA DAMPs release in PCs during storage. Ten PCs prepared by the PRP method were studied. The copy numbers of free mtDNA, total reactive oxygen species (ROS), lactate dehydrogenase (LDH) enzyme activity, pH, and platelet counts were measured on days 0, 3, 5, and 7 of PCs storage in LC-treated and untreated platelets. LDH activity was significantly lower than the control group during 7 days of PCs storage (p = 0.041). Also, ROS production decreased in LC-treated PCs compared to the control group during storage (p = 0.026), and the difference mean of ROS between the two groups was significant on day 3, 5, and 7 (Pday3 = 0.02, Pday5 = 0.0001, Pday7 = 0.031). Moreover, LC decreased the copy numbers of free mtDNA during 7 days of storage (p = 0.021), and the difference mean of the copy numbers of free mtDNA in LC-treated PCs compared to the control group was significant on day 5 and 7 (Pday5 = 0.041، Pday7 = 0.022). It seems that LC can maintain the metabolism and antioxidant capacity of PCs and thus can reduce mitochondrial damage and mtDNA release; consequently, it can decrease DAMPs in PCs. Therefore, it may be possible to use this substance as a platelet additive solution in the future.

Abstract
Purpose The development of biomaterials provides potent promise for the regeneration of neuroretinal cells in degenerative eye diseases and retinal tissue engineering. Biomimetic three-dimensional (3D) microenvironments and specific growth factors motivate the differentiation of human retinal pigment epithelial (hRPE) cells toward a retinal neural lineage. In this study, we evaluated alginate/gelatin (A/G) as a substrate for the culture of hRPE cells. Methods hRPE cells were isolated from neonatal human cadaver globes and cultivated on A/G substrate under different culture conditions, including 30% human amniotic fluid (HAF), 10% fetal bovine serum (FBS), and serum-free Dulbecco's modified Eagle's medium/nutrient mixture F-12 (DMEM/F12). The proliferation of cells in different culture conditions was determined using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide and a cell proliferation assay. Immunocytochemistry and real-time PCR were performed to evaluate the effect of the substrate on hRPE cell differentiation. Results A significant increase in the cell proliferation rate was observed in hRPE cells cultivated on an A/G substrate. Continuous observations demonstrated that hRPE cells formed densely packed, suspended spheroids in DMEM/F12 culture conditions, with dominant transdifferentiation into amacrine cells. Small adherent clusters of hRPE cells in HAF- and FBS-treated cultures represented dedifferentiation toward retinal progenitor cells. These cultures generated amacrine, rod photoreceptors, and bipolar cells. Conclusions These findings indicated that A/G substrate induced neural retinal cell propagation in cultures and would therefore be promising for RPE-based tissue engineering studies.

Abstract
Background and Objectives: Umbilical cord blood (UCB) was used to source hematopoietic stem cells in the past. Despite the apparent advantages of UCB transplantation, virus reactivation poses a considerable danger in allogeneic hematopoietic stem cell transplantation (HSCT). Human Parvovirus B19 is regarded as a potential threat to UCB contamination. This study aimed to evaluate the prevalence of parvovirus B19 in cord blood donors by Semi-Nested PCR. This study is the first large- scale report of the B19 DNA in cord blood donors in Iran.
Materials and Methods: A total of 691 umbilical cord blood were collected under standard procedure. Then, DNA from buffy coat and plasma were extracted, and semi-nested PCR was performed for all samples.
Results: Two out of 691 samples (0.29%) indicated viremia in plasma and buffy coat.
Conclusion: In this line, designing and validating a quantitative PCR assay for detection, quantification, and discrimination of Human B19 DNA genotypes of cord blood donors is necessary to enhance the safety of this source of stem cells.

Abstract
INTRODUCTION The aim of this study was to evaluate and compare two different apheresis and changes in some immunological factors in donors. MATERIAL AND METHODS The cross-sectional study was performed from January 2017 to September 2018. Fifty six male blood donors were randomly divided into two groups. CD4, CD8, and CD25 markers by flow cytometry, and TGFBeta by real-time polymerase chain reaction (RT-PCR) method were done before and 7 days after the apheresis procedure. Independent Sample t-test, Mann-Whitney U Test, Wilcoxon signed ranked test, and Fisher exact test were used. RESULTS WBC in MCS+ group after donation is significantly higher than before donation (P < 0.05) but no significant difference was seen between MCS+ and Trima groups in these two indicators. But in CD4, CD25, and TGFBeta, there was no significant difference between the two groups. CONCLUSION There was no significant difference on CD4, CD25, and TGFBeta gene 7 days after donation.

Abstract
Human platelet antigens (HPAs) are glycoproteins on the platelet surface that a single nucleotide mutation in the coding region gene could lead to the variation of different HPA polymorphisms. These antigens have shown variation among different races and may trigger immune responses during blood transfusion and pregnancy. Genotyping of HPAs is useful for managing these reactions and establishing a platelet registry to decrease platelet transfusion reactions. This study aimed to compare allelic and genotype frequencies of human platelet antigens in the Azeri ethnicity by TaqMan Real-time and polymerase chain reaction with sequence-specific primers (PCR-SSP) methods. DNA was extracted from the whole blood of 100 Azeri blood donors in the Ardabil Blood Transfusion Center. Genotyping of HPA-1 to -5 and -15 was performed by TaqMan Real-time PCR, and PCR-SSP and consistency of results were evaluated. The results of PCR-SSP and TaqMan Real-time PCR showed complete consistency. The allele frequencies were 91.5% and 8.5% for HPA-1a and -1b; 88% and 12% for HPA-2a and -2b; 58% and 42 % for HPA-3a and -3b; 100% for HPA-4a; 91% and 9% for HPA-5a and -5b; 56.5% and 43.5% for HPA-15a and -15b alleles. Not incompatibility was detected in HPAs genotyping by PCR-SSP and TaqMan Real-time PCR so that real-time PCR can be used as a robust and quick method for HPA genotyping. We found differences between Azeri blood donors and previously reported HPAs alleles' frequency in other ethnicities in the country. This fact highlights the need for a platelet registry to recruit platelet donors from different ethnicities and increase the number of donors by using faster methods.

Abstract
In retinal degenerative disorders, when neural retinal cells are damaged, cell transplantation is one of the most promising therapeutic approaches. Optogenetic technology plays an essential role in the neural differentiation of stem cells via membrane depolarization. This study explored the efficacy of blue light stimulation in neuroretinal differentiation of Opto-mGluR6-engineered mouse retinal pigment epithelium (mRPE) and bone marrow mesenchymal stem cells (BMSCs). mRPE and BMSCs were selected for optogenetic study due to their capability to differentiate into retinal-specific neurons. BMSCs were isolated and phenotypically characterized by the expression of mesenchymal stem cell-specific markers, CD44 (99%) and CD105 (98.8%). mRPE culture identity was confirmed by expression of RPE-specific marker, RPE65, and epithelial cell marker, ZO-1. mRPE cells and BMSCs were transduced with AAV-MCS-IRES-EGFP-Opto-mGluR6 viral vector and stimulated for 5 days with blue light (470 nm). RNA and protein expression of Opto-mGluR6 were verified. Optogenetic stimulation-induced elevated intracellular Ca2+ levels in mRPE- and BMS-treated cells. Significant increase in cell growth rate and G1/S phase transition were detected in mRPE- and BMSCs-treated cultures. Pou4f1, Dlx2, Eomes, Barlh2, Neurod2, Neurod6, Rorb, Rxrg, Nr2f2, Ascl1, Hes5, and Sox8 were overexpressed in treated BMSCs and Barlh2, Rorb, and Sox8 were overexpressed in treated mRPE cells. Expression of Rho, Thy1, OPN1MW, Recoverin, and CRABP, as retinal-specific neuron markers, in mRPE and BMS cell cultures were demonstrated. Differentiation of ganglion, amacrine, photoreceptor cells, and bipolar and Muller precursors were determined in BMSCs-treated culture and were compared with mRPE. mRPE cells represented more abundant terminal Muller glial differentiation compared with BMSCs. Our results also demonstrated that optical stimulation increased the intracellular Ca2+ level and proliferation and differentiation of Opto-mGluR6-engineered BMSCs. It seems that optogenetic stimulation of mRPE- and BMSCs-engineered cells would be a potential therapeutic approach for retinal degenerative disorders.

Abstract
Background: Age-related macular degeneration (AMD) is the leading cause of vision loss in the elderly. Although it has been shown that Y402H polymorphism in the CFH gene was strongly associated with AMD in the Iranian population, there were no data on other single nucleotide polymorphisms (SNPs), which have the most significant association with AMD. This study aimed to investigate hot point regions in exon 10 and intron 9. Materials and Methods: One hundred and sixty-six AMD patients and 69 controls were recruited. Their blood was collected in the tubes containing EDTA. Then, DNA was extracted from the blood, and its quality was evaluated. Primers were designed for intron 9 and exon10 sequencing. A viral polymorphisms analysis software named CEQ was used for the analysis of putative polymorphisms. Results: We noticed three polymorphisms in study cases: rs7535263 and C66379A in intron 9 and rs2274700 in exon 10. Based on the McNamara’s test (rs7535263 and rs2274700) and the Phi and Cramer’s test (C66379A), a significant difference was found between the control and patient groups regarding rs7535263 and rs2274700 polymorphisms. Conclusion: We found a synonymous or silent mutation, A473A, rs2274700 in exon 10 in 85% of patients. From two intronic SNPs, just rs7535263 showed association with the disease in studied patients living in Gilan Province, Iran. Although no significant relationship was found between controls and patients regarding the C66379A allele, it would be important that no other sources have reported C66379A polymorphism in AMD yet.

Abstract
PURPOSE The aim of this study was to report the results of the use of real-time polymerase chain reaction (PCR) for the diagnosis of hepatitis B virus (HBV) infection in cornea donors at the Central Eye Bank of Iran. METHODS Between 2014 and 2016, all cornea donors that had negative screening serologic results for hepatitis B (HB) surface antigen, HB surface antibody (Ab), hepatitis C virus Ab, human immune deficiency virus Ab, human T-cell leukemia virus Ab, and syphilis, and positive serology for HB core Ab were subjected to real-time PCR with a detection limit of 400 IU/mL to identify HBV DNA. Positive results for HBV DNA were considered occult HBV infections in these donors. RESULTS Over the 3-year period, 122 out of 10448 cornea donors had negative screening serologic tests outside of HB core Ab. Of which, 90 cases were subjected to real-time PCR. Occult HBV was detected in 11 cases (12.2%), resulting in the rejection of the corresponding corneas. The remaining 79 cases (87.8%) had negative results for HBV DNA and the corresponding corneas were used for transplantation. CONCLUSION Implementation of PCR for the detection of occult HBV in cornea donors is necessary to not only increase the security level of cornea donation but also minimize the rejection rate of donors that have isolated HB core Ab reactivity.

Abstract
In recent years, human umbilical cord blood-derived mesenchymal stem cell (hUB-MSCs) has been regarded as an alternative source for stem cell therapy. In this study, we evaluated the effect of hypoxia preconditioning (HPC) on the expression of Nt-3, GFAP, Nestin, Oct-4 and Nanog genes and proliferative capacity of hUB-MSCs in comparison with normoxic conditions. HPC+Hypoxia protocol includes cultured hUB-MSCs for 15min at 2.5% O2 and after that reoxygenation for 30min at 21% O2 (HPC), and then hypoxia preconditioned hUB-MSCs subjected to 2.5% O2 for 72h (Hypoxia). Conclusively, the results showed that hypoxic preconditioning is an effective strategy for enhancing proliferation capacity of hUB-MSCs, and also can trigger expression of some of the neural genes. In addition, the concept of involvement of oxygen tension in the expression of some of the neural genes of hUB-MSCs would be a good sign of enhanced neural differentiation potential in vitro.

Abstract
BACKGROUND Umbilical cord blood (UCB) is believed to be a highly valuable source of hematopoietic stem cells for transplantation. Objective: To investigate the prevalence of active and latent human cytomegalovirus (CMV) infection in UCB donors in Iranian population. METHODS A total of 825 UCB samples was collected under standard procedures and analyzed for the presence of CMV DNAs in buffy coat (latent infection) and plasma (active infection). DNA was extracted from buffy coat and plasma samples separately and tested with quantitative real-time PCR. All positive samples were checked by ELISA for IgG and IgM anti-CMV antibody. RESULTS Latent CMV infection was detected in 17 (2%) buffy coat samples with a low level of viral load, which indicated the presence of latent viral infection in donors. None of the plasma samples were found positive for CMV DNA reflecting no active infection. In the 17 positive samples, CMV viral load was 91-104 (mean: 100) copies/mL. All samples positive for viral DNA were also found positive for CMV IgG antibody by ELISA. No CMV IgM antibody was detected in positive samples. CONCLUSION CMV is still the most important virus that infects hematopoietic stem cells and could be dangerous, especially for immunocompromized transplant recipients. We therefore suggest using real-time PCR for the detection and quantification of the viral DNA in buffy coat and plasma of UCB donors. PCR of plasma for detection of CMV and antibody assay for CMV infection add no more sensitivity for the detection of latent CMV infection in UCB donors.

Abstract
Umbilical cord blood (UCB) is one of the most important sources of hematopoietic stem cells which can be used for transplantation. The transplanted CB stem cells might cause infections in recipients. The aim of this study is to evaluate Human Herpes Virus8 (HHV8) as a Rhadinovirus among CB samples in order to assess safety of cord blood stem cells transplantation. To assess this aim, we surveyed 800 cord blood specimens by Real Time PCR.The overall HHV8 incidence in cord blood mononuclear cells was 1.38% and none of them was in lytic phase of HHV8. The authors suggest further HHV8 study on CB samples for transplantation.

Abstract
OBJECTIVE Umbilical cord blood (UCB) has been a reasonable alternative to granulocyte colony-stimulating factor-mobilized peripheral blood or bone marrow, as a source of hematopoietic stem cells with a lower risk of graft-versus-host disease. In immunocompromised hosts after transplantation, the risk of viral infection in adults, especially with beta-herpesviruses such as human herpesvirus-7 (HHV-7), may be increased. This virus in immunocompromised patients can be reactivated from latency and converted to an active phase. Therefore, light-upon-extension real-time polymerase chain reaction (PCR) was developed to assess the prevalence and load of HHV-7 in the plasma and buffy coat of donors. METHODS About 825 UCB samples under standard protocol from donors were collected. Then, DNA from plasma and buffy coat was extracted and quantitative real-time PCR was performed with light-upon-extension primers. RESULTS Overall, HHV-7 was detected in 3.64% (30/825) of UCB donors. HHV-7 DNA was detected in 26 (3.2%) buffy coat samples (latent infection), and only 4 (0.48%) of them were positive for HHV-7 DNA in plasma samples (active infection); the mean HHV-7 viral load was 1.31 × 10(1) copies/mL in latent infection, and 1.94 × 10(5) copies/mL in active infection. CONCLUSIONS We suggest that real-time PCR in plasma and buffy coat could be a useful method to detect active and latent HHV-7 infection in UCB donors and determine its role in subsequent transmission events.

Abstract
BACKGROUND Approximately 10% of new breast cancer patients will present with overt synchronous metastatic disease. The optimal local management of those patients is controversial. Several series suggest that removal of the primary tumour is associated with a survival benefit, but the retrospective nature of those studies raises considerable methodologic challenges. We evaluated our clinical experience with the management of such patients and, more specifically, the impact of surgery in patients with synchronous metastasis. METHODS We reviewed patients with primary breast cancer and concurrent distant metastases seen at our centre between 2005 and 2007. Demographic and treatment data were collected. Study endpoints included overall survival and symptomatic local progression rates. RESULTS The 111 patients identified had a median follow-up of 40 months (range: 0.6-71 months). We allocated the patients to one ot two groups: a nonsurgical group (those who did not have breast surgery, n = 63) and a surgical group (those who did have surgery, n = 48, 29 of whom had surgery before the metastatic diagnosis). When compared with patients in the nonsurgical group, patients in the surgical group were less likely to present with T4 tumours (23% vs. 35%), N3 nodal disease (8% vs. 19%), and visceral metastasis (67% vs. 73%). Patients in the surgical group experienced longer overall survival (49 months vs. 33 months, p = 0.01) and lower rates of symptomatic local progression (14% vs. 44%, p < 0.001). CONCLUSIONS In our study, improved overall survival and symptomatic local control were demonstrated in the surgically treated patients; however, this group had less aggressive disease at presentation. The optimal local management of patients with metastatic breast cancer remains unknown. An ongoing phase iii trial, E2108, has been designed to assess the effect of breast surgery in metastatic patients responding to first-line systemic therapy. If excision of the primary tumour is associated with a survival benefit, then the preselected subgroup of patients who have responded to initial systemic therapy is the desired population in which to put this hypothesis to the test.

Abstract
Background: Approximately 10% of new breast cancer patients will present with overt synchronous metastatic disease. Controversy exists about the optimal local management of these patients. While several series suggest that removal of primary tumour is associated with a survival benefit, the retrospective nature of these studies raises considerable methodological challenges. We decided to evaluate the experience at our centre around the impact of surgery in patients with synchronous metastasis.
Method: Case records of all patients seen with primary breast cancer and concurrent distant metastases between 2005 to 2007 were reviewed. Demographic and treatment data was collected. The study endpoints compared both overall survival and symptomatic local progression rates between patients who had breast surgery and those who did not.
RESULTS: 111 patients were identified. Median follow-up 40 months (0.6-71 months). Patients were divided into two groups: those patients who underwent breast surgery (n=48; 29/48 had surgery immediate prior to metastatic diagnosis) and those that did not have surgery(n = 63). The surgical group were less likely to present with T4 tumours (20% vs 36%), N3 nodal disease (8% vs 19%) and visceral metastasis (67% vs 73%)when compared with non-surgical group. Improved overall survival (49 months vs 33 months; p=0.01) and less symptomatic local progression rates ( 15% vs 43%, p < 0.001 ) were seen in the surgical group compared to the non-surgical group.
CONCLUSIONS: The optimal local management of patients with metastatic breast cancer is unknown. Despite the surgery group demonstrating an improved overall survival and symptomatic local control, this group had less aggressive disease at presentation. These results confirm the need for prospective randomized studies. E2108, an ongoing Phase III Trial, was designed to assess the effect of breast surgery in metastatic patients responding to first line systemic therapy. If excision of the primary tumour is associated with a survival benefit, then the pre-selected subgroup of patients that have responded to initial systemic therapy is the desired population to put this hypothesis to test.

Abstract
BACKGROUND In recent years, the confidential unit exclusion (CUE) option has been used to increase blood safety at blood transfusion centers in several countries. The epidemiologic characteristics of diseases and demographic characteristics of patients vary in different countries; therefore, we investigated whether the CUE option is useful in Iran. In this study, we determined the prevalences of hepatitis B virus (HBV) and hepatitis C virus (HCV) in CUE-positive and CUE-negative units, as well as the efficacy of the CUE option. OBJECTIVES The aim of this study was to evaluate the efficacy of the CUE option in reducing the prevalences of HBV and HCV in blood units. PATIENTS AND METHODS All donors were tested for the HCV antibody (anti-HCV) and hepatitis B surface antigen (HBsAg). Supplemental tests were performed to confirm the presence of viruses in the units that tested positive. In total, 2000 units (1000 CUE-positive units and 1000 CUE-negative units) were tested using the nucleic acid testing (NAT) method. The prevalence of infectious markers was estimated in all demographic subgroups. RESULTS The prevalences of HBV and HCV markers were higher in donors who opted for CUE than in those who did not. The CUE option had low sensitivity (21.5%) and positive predictive value (PPV; 20.9%) for the markers. Most of the donors who opted for CUE for the first time were men with low levels of education. CONCLUSIONS The CUE option has low sensitivity and PPV, and its effectiveness in reducing the transmission of infectious diseases through window-period units is minimal. The CUE process can be continued in Iran because Iran is geographically located in a region where HBV is endemic; however, higher levels of education are necessary to make this process effective.

Abstract
In recent years, a new view of dendritic cells (DCs) as a main regulator of immunity to induce and maintain tolerance has been established. In vitro manipulation of their development and maturation is a topic of DC therapeutic application, which utilizes their inherent tolerogenicity. In this field, the therapeutic potential of antisense, siRNA, and blocking antibody are an interesting goal. In the present study, the efficiency of these three methods--siRNA, antisense, and blocking antibody--against CD40 molecule and its function in DCs and BCL1 cell line are compared. DCs were separated from mouse spleen and then cultured in vitro using Lipofectamine 2000 to deliver both silencers; the efficacy of transfection was estimated by flow cytometry. mRNA expression and protein synthesis were assessed by real time-PCR and flow cytometry, respectively. By Annexin V and propidium iodine staining, we could evaluate the viability of transfected cells. Knocking down the CD40 gene into separate groups of DCs by siRNA, antisense, and blocking antibody treated DCs can cause an increase in IL-4, decrease in IL-12, IFN-γ production, and allostimulation activity. Our results indicated that, in comparison to antisense and blocking antibody, siRNAs appear to be quantitatively more efficient in CD40 downregulation and their differences are significant.

Abstract
BACKGROUND Dendritic cells (DCs) are ideal accessory cells in the field of gene therapy. Delivery of DNA and siRNA into mammalian cells is a useful technique in treating various diseases caused by single gene defects. Selective gene silencing by small interfering RNAs (siRNAs) and antisense oligodeoxynucleotides (ODN)s is an efficient method for the manipulation of cellular functions. An efficient, functional delivery system with no toxicity problems would be attractive. OBJECTIVE We compared two commercially available cationic lipids, Lipofectamine and FuGENE6, in the delivery of both siRNA and antisense ODNs into mice spleen-derived DCs. METHODS Cellular uptake was measured by the means of fluorescein-labelled non-silencing siRNA and antisense ODNs as a model system using flow cytometry. Cytotoxicity of the two delivery systems was compared with propidium iodide and annexin-V staining, and quantified with flow cytometry. The efficiency of our oligonucleotide delivery systems was compared by measuring CD40 expression by flow cytometry. RESULTS CD40 expression in DCs was 38%. After siRNA transfection by Lipofectamine, CD40 expression decreased to 13%, and after transfection by FuGENE6, it decreased to 18%. The difference was statistically significant. CD40 down regulation in DCs transfected with the two different antisense sequences by Lipofectamine was 21% and 23%, and down regulation after transfection by FuGENE6 was 19% and 18%, respectively. The differences were not statistically significant. The effects of siRNA and antisense ODNs were specific. CONCLUSION Lipofectamine was a more potent delivery system in siRNA effect, followed by FuGENE6. There was no significant difference between Lipofectamine and FuGENE6 as a delivery system of antisense ODNs.

Abstract
Busulfan and cyclophosphamide (BuCy) are currently the most widely used myeloablative regimen to treat malignancies with allogeneic stem cell transplantation. Fludarabine has considerable efficacy in both immunosuppression and tumor cells killing with a minimal extramedullary toxicity. We evaluated the efficacy of 40 mg/m(2) fludarabine i.v. for 5 days and busulfan 4 mg/kg/day p.o. for 4 days as myeloablative conditioning regimen in 70 patients (median age 24 years) with acute leukemia or chronic phase of myelogenous leukemia. They all had human leukocyte antigen-matched sibling donors. The patients received 10 mug/kg granulocyte colony stimulating factor (GCSF), 24 h after stem cell infusion until engraftment occurred. Graft-versus-host disease (GVHD) prophylaxis included 3 mg/kg cyclosporine-A i.v. from day -2 to +6 followed by 12 mg/kg p.o. until day +60. The median time of neutrophil recovery (>0.5 x 109/l) and platelet recovery (>20 x 109/l) were 10 and 12 days, respectively. Mucositis (93%) and hepatic toxicity (16%) resolved with conservative therapy. The incidence of acute GVHD grade I-II and III-IV were 38.6 and 15.7% respectively. Overall survival and disease-free survival were 71 and 64% respectively with 17 months median follow-up for surviving patients. We conclude that FluBu may be used as a substitute for BuCy with almost the same efficacy and with a lower transplant adverse effect but to increase anti-leukemic effects, especially in acute lymphoblastic leukemia patients, it needs some modifications.

Abstract
AIM: To study the effect of some genes especially those involved in cell cycle regulation on hepatocellular carcinoma.
METHODS: Paraffin-embedded tissue samples of 25 patients (18 males and 7 females) with hepatocellular carcinoma were collected from 22 pathology centers in Tehran during 2000-2001, and stained using immunohistochemistry method (avidin-biotin-peroxidase) for detection of p53, cyclinD1, RB1, c-fos and N-ras proteins.
RESULTS: Six (24%), 5 (20%), 12 (48%) and 2 samples (8%) were positive for p53, cyclinD1, C-fos and N-ras expression, respectively. Twenty-two (88%) samples had alterations in the G1 cell-cycle checkpoint protein expression (RB1 or cyclinD1). P53 positive samples showed a higher (9 times) risk of being positive for RB1 protein than p53 negative samples. Loss of expression of RB1 in association with p53 over-expression was observed in 4 (66.7%) of 6 samples. Loss of expression of RB1 was seen in all cyclinD1 positive, 20 (90.9%) N-ras negative, and 11 (50%) C-fos positive samples, respectively. CyclinD1 positive samples showed a higher (2.85 and 4.75 times) risk of being positive for c-fos and N-ras expression than cyclinD1 negative samples.
CONCLUSION: The expression of p53, RB1 and c-fos genes appears to have a key role in the pathogenesis of hepatocellular carcinoma in Iran. Simultaneous overexpression of these genes is significantly associated with their loss of expression during development of hepatocellular carcinoma.

Abstract
BACKGROUND HBV infection is a serious global heath problem. It is crucial to monitor this disease more closely with a non-invasive marker in clinical trials. We aimed to evaluate the predictive value of serum hyaluronate for the presence of extensive liver fibrosis and inflammation. METHODS 28 healthy volunteers and 65 patients with HBeAg negative chronic hepatitis B were enrolled. Liver biopsies scored according to Ishak system. Association of serum hyaloronate with liver fibrosis and inflammation were assessed, and cut off points for serum hyaluronate levels were identified by receiver operating characteristics (ROC) curves and their values for prediction of fibrosis and inflammation were assessed. RESULTS In patients with CHB serum hyaluronate had the most significant correlation and predictive values for the liver fibrosis and inflammation comparing to the other variables. At the cut off point of 126.4 ngm/ml it could discriminate extensive fibrosis from milder ones with sensitivity of 90.9% and specificity of 98.1%. With the same value it could discriminate extensive inflammation from their milder counterparts with sensitivity of 63.6% and specificity of 92.6%. CONCLUSION Serum hyaluronate was the best predictor of extensive liver fibrosis and inflammation and it could discriminate subgroups of patients with chronic hepatitis B. It could be used as a non-invasive test to monitor these patients more closely with developing anti viral agents in clinical trials.

Abstract
Genetic aberrations have emerged as major prognostic factors for patients with multiple myeloma (MM). We evaluated 126 MM patients for t(4;14) or t(11;14), 13q or p53 deletions and correlated the number of genetic aberrations with patient's clinical outcome following undergoing autologous stem cell transplantation. We demonstrate the significance of genetic-based risk classification that clearly segregate patients into low (no genetic abnormalities or only t(11;14)), intermediate (any one of the genetic abnormalities other than t(11;14)) and high-risk groups (any two or more of the genetic abnormalities other than t(11;14)). High-risk patients do not benefit from stem cell transplant and should be offered alternative therapies.

Abstract
We compared the effects of cyclosporin A (CsA) alone as graft-versus-host disease (GVHD) prophylaxis vs cyclosporine with short-course methotrexate (MTX) in patients with thalassemia. In all, 140 patients were enrolled in this study. The first group, of 50 patients, received CsA alone at 3 mg/kg i.v. from day -2 to +5 followed by 12.5 mg/kg p.o., which was tapered according to the patient's condition. The other group, of 90 patients, received the combination of CsA+MTX in which CsA was used with the above-mentioned dose and MTX was on 10 mg/m(2) day +1 and 6 mg/m(2) on days +3 and +6. Incidence of acute GVHD grade II-IV in the CsA group was 78% and in the CsA+MTX group was 52.2%, which was statistically significant (P=<0.001). There were no significant differences in the incidence of chronic GVHD between the two groups. The mean neutrophil engraftment to 0.5 x 10(9)/l was 14 and 23 days for CsA group and CsA+MTX group, respectively (P=<0.001). There were no significant differences for platelet recovery between the two groups. Graft failure in the CsA and CsA+MTX groups was seven (14%) and nine (10%) patients, respectively (P=0.58). Overall survival in the CsA and CsA+MTX groups was 77 and 85%, respectively. Disease-free survival in the CsA and CsA+MTX groups were 58 and 80%, respectively.

Abstract
OBJECTIVE Occult hepatitis B virus (HBV) infection is characterized by presence of HBV infection with undetectable hepatitis B surface antigen (HBsAg). Diagnosis of occult HBV infection requires sensitive HBV-DNA polymerase chain reaction (PCR) assay. Occult hepatitis B is a new entity and the prevalence of it and its clinical importance has not been investigated yet in Iran. The aim of this study is to investigate the prevalence and clinical importance of occult hepatitis B among chronic liver disease patients in Iran. METHODS We studied 35 consecutive paraffin-embedded liver tissues cases referred to Research Center for Gastroenterology and Liver Diseases, Tehran, Iran during the year 2001 to 2002 for liver biopsy due to its elevation of alanine aminotransferase (ALT) levels for more than 6 months. Liver biopsies were reviewed and HBV-DNA and HBsAg and Hepatitis B core antigen were assayed in liver tissue by PCR and immunohistochemistry (IHC). RESULTS Our patients with chronic liver disease (CLD) included hepatitis C (77.1%), cryptogenic liver disease (20%), and autoimmune hepatitis (2.9%). Histologically, chronic hepatitis, cirrhosis and non-specific changes were reported. Hepatitis B virus-DNA was detectable in 8 (22%) patients; however, IHC was negative in all. CONCLUSION Occult hepatitis B is relatively frequent among patients with CLD in Iran. It maybe associated with more advanced liver pathology (cirrhosis) and more aggressive clinical course (decompensated cirrhosis). Occult HBV infection causes strong suppression of viral gene expression.
