Abstract
In this research, a composite coating with Al2O3 and ZrO2 particles have been applied on AZ31 magnesium alloy by micro-arc oxidation (MAO) technique. The alkaline electrolyte included a constant based composition and different composition of the Al2O3 and ZrO2 additives. Microstructure observations reveal that the surface pores of composite coating reduced during addition of ZrO2 and Al2O3 ceramic particles. The hardness of coating increased from about 380 for non-added to 620 MPa for Al2O3+ZrO2 added coating and wear rate reduced about 8 times. Wettability of the coating increased by incorporation of Al2O3 and/or ZrO2 particles while, Al2O3 is more effective than ZrO2. Addition of the ceramic particles enhanced the hydrophilicity properties of surface in wettability test and a contact angle of 43° was obtained for coating including Al2O3+ZrO2. The antibacterial properties of MAO coatings showed that S. aureus bacterium is more sensitive to the zirconia and alumina particle than S. typhimurium bacterium after 24 h of incubation.

Abstract
Naphthothiophenes were prepared from commercially available 2,3-dibromothiophenes in two steps by one-pot Suzuki/Sonogashira or Sonogashira/Suzuki coupling reactions, followed by intramolecular alkyne-carbonyl-metathesis reactions. The final cyclization reaction proceeds in the presence of p-toluenesulfonic acid and provides a rapid access to two series of isomeric naphthothiophenes.

Abstract
Dibenzocycloheptanones (dibenzotropones) were prepared by Brønsted acid mediated intramolecular alkyne-carbonyl metathesis (ACM) reactions. The cyclization precursors are readily available by Sonogashira reaction of 2-bromobenzoyl chloride with terminal alkynes, followed by Suzuki reactions with benzaldehydes. The ACM reactions are highly modular and atom economic and allow for the construction of two regioisomeric series of dibenzotropones.

Abstract
AIMS Wolfram syndrome (WS) is a rare recessive neurodegenerative disorder characterized by diabetes mellitus and optic atrophy. Mortality and morbidity rate of the disease is high in adulthood due to neurological and respiratory defects. So far, two WS genes, WFS1 (more than 90% of cases) and CISD2, have been identified. In the present study, we aimed to determine the role of WFS2 in a group of Iranian WS families. METHODS We recruited 27 families with the clinical diagnosis of WS. Homozygosity mapping was implemented using short tandem repeat polymorphic markers and bi-directional sequencing of the CISD2 gene in families negative for WFS1 mutations. The candidate variant was checked among family members. In silico analysis and protein modeling were applied to assess the pathogenic effect of the variant. Tetra-primers ARMS PCR was set up for checking the variant in 50 ethnic-matched controls. RESULTS One family showed homozygosity by descent at WFS2. A novel missense variant, c.310T > C (p.S104P), was found in exon 2 of the CISD2 gene. Computational predictions revealed its pathogenic effect on protein structure, function, and stability. Parents and his healthy brother were heterozygous for the variant. The variant was not observed in the control group. CONCLUSIONS This is the first study that elucidates the role of the CISD2 gene among Iranian WS families with a novel disease-causing missense variant. Next-generation sequencing could unravel disease-causing genes in remained families to expand genetic heterogeneity of WS.

Abstract
PURPOSE Wolfram syndrome (WS) is a rare genetic disorder described by a pattern of clinical manifestations such as diabetes mellitus, diabetes insipidus, optic nerve atrophy, sensorineural hearing loss, urinary tract abnormalities, and psychiatric disorders. WFS1 and WFS2 loci are the main genetic loci associated with this disorder. METHODS In the current study, we investigated associations between these loci and WS via STR markers and homozygosity mapping in 13 Iranian families with WS. All families were linked to WFS1 locus. RESULTS Mutation analysis revealed four novel mutations (Q215X, E89X, S168Del, and E391Sfs*51) in the assessed families. Bioinformatics tools confirmed the pathogenicity of the novel mutations. Other identified mutations were previously reported in other populations for their pathogenicity. CONCLUSIONS The current study adds to the mutation repository of WS and shows a panel of mutations in Iranian population. Such panel would facilitate genetic counseling and prenatal diagnosis in families with WS cases.

Abstract
Translocations are the most common structural abnormality in the human genome. Carriers of balanced chromosome rearrangements exhibit increased risk of abortion or a chromosomally-unbalanced child. The present study was carried out in 2017 at the Iranian Blood Transfusion Research Center. This study reported a rare chromosomal disorder with 4p duplication and 10q distal deletion syndrome which is associated with various complications at birth. Defects included the following characteristics: dysmorphic facial characteristic, hand or foot anomalies, growth retardation, developmental delay, strabismus, heart defects and renal anomalies. Cytogenetic analysis and array CGH were performed and, for the first time, we reported a patient with trisomy 4p16.3p12 and monosomy 10q26.3. The patient was found to have: arr 4p16.3p12 (37,152-45,490,207) x3, 10q26.3 (134,872,562-135,434,149) x1 genomic imbalances.

Abstract
PURPOSE Basal cell carcinoma (BCC) is the most prevalent cancer worldwide. Different mechanisms are proposed to be involved in its pathogenesis such as oxidative stress. Oxidative stress, which is the consequence of the disruption of redox balance in favor of oxidants, is involved in the initiation or progression of many tumors. Thioredoxin reductase (TrxR) is a key enzyme of the thioredoxin (Trx) system, containing Trx and TrxR and NADPH, which is one of the main cellular oxidoreductases with an essential role in cellular health and survival through providing and maintaining redox balance. Therefore, we aimed to study and compare the activity and tissue distribution of TrxR in tumoral tissue and its healthy margin in patients with BCC. METHODS After biopsy and taking samples from 18 patients, TrxR activity was measured using a commercial kit and its tissue distribution was assessed immunohistochemically. RESULTS Both the activity and tissue distribution of TrxR in tumoral tissues were significantly higher compared to their healthy margins. Regarding the tissue distribution, this significant increase in TrxR in tumoral tissues was documented based on both staining intensity and abundance of positive cells in immunohistochemistry. CONCLUSIONS Based on these results, it is concluded that TrxR is involved in the pathogenesis of BCC; however, more investigations are required to clarify whether this increase is a consequence of BCC or it is an initiating mechanism.

Abstract
BACKGROUND Beta thalassemia major and its treatment by hematopoietic stem cell transplantation can have deleterious effects on bone integrity and a main part of such effects is due to their deleterious effects on endocrine systems. So, we assessed the effects of endocrine changes during HSCT (Hematopoietic Stem Cell Transplantation) on growing bones of pediatric thalassemic patients. METHODS Bone-specific alkaline phosphatase and osteocalcin (bone formation markers), N-terminal telopeptide (NTX, bone resorption marker), calcium (Ca), phosphorus (P), alkaline phosphatase (Alk ph), parathyroid hormone (PTH), vitamin D (vit D), prolactin, luteinizing hormone (LH), follicle-stimulating hormone (FSH), thyroxine (T4), triiodothyronine (T3), thyroid-stimulating hormone (TSH), insulin-like growth factor 1 (IGF-1), testosterone (in males) or estradiol (in females), measured in 20 major thalassemic patients with mean age of 10.8±3.9 years. Parameters at the baseline (before HSCT), and 1 month and 3 months after HSCT. RESULTS After stem cell transplantation, changes of mean serum levels of NTX, osteocalcin, prolactin, LH, T4, IGF-1, testosterone (in males), Ca, Alk ph, PTH, and vit D were not significant, but bone specific Alk ph, P, T3, TSH, FSH and estradiol changed significantly (P=0.013, P=0.001, P=0.48, P=0.02, P=0.04 and P=0.001, respectively). After one month, there was a significant positive relationship between osteocalcine and T3 (p= 0.009). After 3 months, also, there was a significant positive relationship between osteocalcine and T3 and T4 as well as a negative one with IGF-1 (P<0.001, P<0.02 and P<0.03, respectively). CONCLUSIONS Endocrine disorders do not appear to have an overall positive or negative effect on bone metabolism (anabolism or catabolism) in HSCT pediatric thalassemic patients in short term (three months).

Abstract
Wolfram syndrome also known as DIDMOAD (Diabetes Insipidus, Diabetes Mellitus, Optic Atrophy, and Deafness) is a rare neurodegenerative autosomal recessive disorder. There is evidence of variable expressivity both in patients and heterozygous carriers. In this study, we describe three Persian Wolfram syndrome families with differences in the age of onset, signs and symptoms of the disease. We clinically evaluated affected families for verifying WS clinical diagnosis. After linkage analysis via 5 STR markers, molecular analysis for WFS1 was performed by direct sequencing for patients and available family members. Three homozygous mutations were identified including c.1885 C>T, c.2205C>A both in exon 8 and c.460+1G>A in intron 4. The mutation c.2205C>A was found to be novel. We report interesting phenotype-genotype correlations: homozygous c.1885C>T and c.2205C>A variants were correlated with quite different disease severity and onset in the siblings. We report a rare case of WS with homozygous c.1885C>T who is married and has a healthy child. c.460+1G>A showed a possible partial dominant inheritance put forth by a heterozygous parent showing partial WS symptoms while her daughter displayed typical WS symptoms. Due to variable expressivity, detailed clinical examination and molecular diagnostics should be used to confirm WS and a more exact recurrence risk data.

Abstract
Some of the genotypes of cytokines are associated with acute graft versus host disease after bone marrow transplantation. The purpose of the present investigation was to find out the possible association between transforming growth factor beta-1 (TGF-beta1) codon 25 polymorphism (rs:1800471) and acute graft versus host disease (aGVHD) after bone marrow transplantation from the sibling with the similar HLA among the Iranian population. In this retrospective case-control investigation, 172 subjects including 86 Iranian patients and their siblings with the similar HLA as donor/recipient pairs were recruited. All of the patients were diagnosed with one group of blood disorder consisting of Acute Myeloid Leukemia (AML)=40, Acute Lymphoblastic Leukemia (ALL)=25 and Chronic Myeloid Leukemia (CML)=21. PCR-SSP method was carried out to ascertain TGF- beta1 codon 25 G/C polymorphism genotypes. The frequency of TGF- beta1 codon 25 GG, GC and CC genotypes among all cases were 77.3%, 21.5% and 1.2%, respectively. Recipients with the GG genotype developed severe aGVHD significantly more than those with CC or GC genotypes (Odds Ratio =12.133, P=0.015). Genetic background of TGF-beta1 may be involved in aGVHD development and/or severity in the patients who received Bone Marrow Transplantation (BMT) from their siblings with the similar HLA among the Iranian population.

Abstract
One of the most fascinating areas of research within the field of histocompatibility at present time concerns an observation that a major human histocompatibility system, human leucocyte antigen (HLA), is deeply involved in the development of a great number of diseases. Major histocompatibility complex is the most polymorphic system in the genome of different species. Recognition of HLA alleles could be useful in transplantation and disease studies. Genetic construct of HLA DRB1 was studied in Iranian normal populations and patients with aplastic anaemia and Fanconi's disease. DNA was extracted from the whole blood of 466 normal, 35 aplastic anaemia and 10 Fanconi's individuals. Then DRB1 gene polymorphism was studied by polymerase chain reaction-sequence-specific primer method. The HLA DRB1 gene analysis showed increase of DRB1*07 in aplastic anaemia patients compared to normal population (P = 0.02). According to this study, the frequency of DRB1*07 in normal individuals was 8.3, and in aplastic anaemia patients, 15.7%. Additionally, the frequency of DRB1*04 in normal, aplastic anaemia and Fanconi's individuals was 10, 5.7 and 20%, respectively. Our results of investigation showed correlation between some HLA alleles with the studied diseases. We reported the frequency of various DR types in aplastic and Fanconi's patients. This study could imply the possible role of HLA-DRB1*07 in the incidence of aplastic anaemia. Moreover, the frequency of DRB1*04, DRB1*03 and DRB1*15 alleles showed intermediate correlation with Fanconi's anaemia.

Abstract
BACKGROUND Certain cytokine genotypes are associated with acute graft versus host disease (aGVHD) after bone marrow transplantation (BMT). The present study aimed to determine existing association between TGF-beta1 codon 10 polymorphism and aGVHD after HLA-identical sibling BMT in the Iranian population. MATERIAL/METHODS In a retrospective case-control study, 168 subjects including 84 Iranian HLA-identical sibling BMT donor/recipient pairs were recruited. All of the patients were affected by hematological malignancies (AML=39, ALL=23 and CML=22). PCR-SSP method was performed to determine TGF-beta1 codon 10 T/C polymorphism genotypes. RESULTS The frequency of TGF-beta1 codon 10 TT, TC and CC genotypes among all subjects were 26.8%, 33.3% and 39.9% respectively. Recipients with the T allele developed aGVHD significantly less than those without the T allele (odds ratio =0.334, P=0.026). CONCLUSIONS Genetic background of TGF-beta1 may be involved as a protective factor in the development of aGVHD in HLA-matched sibling BMT in Iranian population. Moreover, this finding may indicate that the genetic markers in Iranians are, at least to some extent, linked to distinct genetic event from Japanese.
