Abstract
INTRODUCTION During the COVID-19 pandemic, there was a remarkable increase in public volunteering for the care of hospitalized patients. They faced challenges during their voluntary care provision. This study aimed at exploring public volunteers' experiences of the challenges of the voluntary care provision to hospitalized patients with COVID-19. METHODS A descriptive qualitative study with an inductive content analysis method was conducted, 2022-2023. Eighteen public volunteers providing care to hospitalized patients with COVID-19 were purposefully selected among 10 hospitals, specialized in COVID-19 care in Tehran and Shiraz, Iran. Data were collected over 7 months through in-depth semistructured interviews and concurrently analyzed using conventional content analysis methods. FINDINGS The challenges of voluntary care provision to hospitalized patients with COVID-19 were illustrated in five main categories, each with two subcategories. The categories included structural challenges, interpersonal conflicts, financial constraints, covert participation and the deteriorating condition of care provision. The subcategories comprised lack of volunteer recruitment bases, ineffective organization of voluntary activities, pervasive distrust, heightened risk of clinical errors, conflicts between volunteer commitments and primary occupation, lack of financial support, lack of family support, isolation by friends, mental trauma and physical exhaustion. CONCLUSION Public volunteers encounter diverse challenges while providing care to hospitalized patients with COVID-19, which negatively impacts their motivation to serve. By addressing these challenges, we can create a more supportive environment for volunteers and enhance the quality of care provided to patients during public health emergencies. Identifying such challenges can assist healthcare managers and policymakers develop effective strategies to mitigate mounting difficulties and enhance volunteer services, thereby improving the overall quality of care provided to patients during public health crises. PATIENT CONTRIBUTIONS Participants were identified and recruited after the study objectives were explained in person to the managers. The participants were approached and interviewed by one author. Participation was voluntary and the participants did not receive any financial compensation for their time.

Abstract
Fetal development is a critical phase in prenatal care, demanding the timely identification of anomalies in ultrasound images to safeguard the well-being of both the unborn child and the mother. Medical imaging has played a pivotal role in detecting fetal abnormalities and malformations. However, despite significant advances in ultrasound technology, the accurate identification of irregularities in prenatal images continues to pose considerable challenges, often necessitating substantial time and expertise from medical professionals. In this review, we go through recent developments in machine learning (ML) methods applied to fetal ultrasound images. Specifically, we focus on a range of ML algorithms employed in the context of fetal ultrasound, encompassing tasks such as image classification, object recognition, and segmentation. We highlight how these innovative approaches can enhance ultrasound-based fetal anomaly detection and provide insights for future research and clinical implementations. Furthermore, we emphasize the need for further research in this domain where future investigations can contribute to more effective ultrasound-based fetal anomaly detection.

Abstract
Diabetes mellitus (DM) is a metabolic disease that activates several molecular pathways involved in neurodegenerative disorders. Metformin, an anti-hyperglycemic drug used for treating DM, has the potential to exert a significant neuroprotective role against the detrimental effects of DM. This review discusses recent clinical and laboratory studies investigating the neuroprotective properties of metformin against DM-induced neurodegeneration and the roles of various molecular pathways, including mitochondrial dysfunction, oxidative stress, inflammation, apoptosis, and its related cascades. A literature search was conducted from January 2000 to December 2022 using multiple databases including Web of Science, Wiley, Springer, PubMed, Elsevier Science Direct, Google Scholar, the Core Collection, Scopus, and the Cochrane Library to collect and evaluate peer-reviewed literature regarding the neuroprotective role of metformin against DM-induced neurodegenerative events. The literature search supports the conclusion that metformin is neuroprotective against DM-induced neuronal cell degeneration in both peripheral and central nervous systems, and this effect is likely mediated via modulation of oxidative stress, inflammation, and cell death pathways.

Abstract
BACKGROUND Opiate abuse has been critically increased in the world, especially in Iran. Owing to the association of opiate use with multiple human cancers and neurological disorders, seeking for genetic and epigenetic effects of opium can pave the way for early diagnosis of major health defects in addicted users. Accordingly, the present study aimed to determine the methylation status of the promoter of two genes, which are actively involved in neurodevelopment and cancer evolution. METHODS DNA was isolated from peripheral blood of 28 opium abusers and 19 healthy controls and then subjected to sonication. Sonicated DNAs undergone methylated DNA immunoprecipitation-real time polymerase chain reaction (MeDIP-Real Time PCR) using specific primer pairs designed for HOXA9 and NISCH genes. Obtained data were analyzed using SPSS software. FINDINGS HOXA9 and NISCH genes were found to be significantly methylated in addicted users compared to controls (P<0.001) which was significantly associated with the mean of the age regarding HOXA9 gene (P=0.002). Neither opium amount nor duration or route of using was associated with the methylation status of HOXA9 or NISCH genes. CONCLUSION Hypermethylation of HOXA9 and NISCH genes as tumor suppressor in opium-addicted individuals can be considered as confirmatory evidence for carcinogenesis of opium. Further studies are required to figure out the role of epigenetic alterations in cancer evolution among opium users.

Abstract
This current work expresses numerical simulation of forced turbulent flow convection in a grooved cylinder. Rectangular grooves with a spacing of A = 1, A = 1.1, and A = 1.3, and groove depth to cylinder diameter of e/D = 0.1 and 0.2 were considered. This research concentrates on the effect of groove depth, location of the grooves and CuO nanoparticles on the heat transfer for Reynolds numbers 10000, 12,500, 15,000 and 17,500 in volume fractions of 0, 1, 2, 3 and 4% of nanoparticles. Results show that grooves improve heat transfer. This behavior at a lower A ratio results in a significant Nu number increase so that the highest Nu number occurs for A ratio of 1, 1.1 and 1.3. Increasing e/D ratio, due to increasing the channel section in this area, results in loss of velocity and dissipation of flow momentum, resulting in lower convective heat transfer and lower Nu number. Changing the pitch for e/D = 0.1 results in a 1.1 to 1.6 times increase of Nu number compared with the smooth channel, and for e/D = 0.2 this value is 1.1-1.5 times the smooth channel for similar Re, φ and geometry. Changing groove pitch at e/D = 0.1 results in a 2.1-2.9 times increase in friction factor compared with the smooth channel in similar conditions. For e/D = 0.2, this increase is 1.8-2.8 times the smooth channel. In low Re, the thermal performance is higher than in higher velocities. This is because the grooved channel acts as a smooth channel at high Re, and the average Nu does not have significant growth.

Abstract
Background: The antioxidant activity of Bane (Pistacia atlantica) has been proved in different researches. This study evaluated the potential of Bane (Pistacia atlantica) essential oil (as a natural antioxidant) on the oxidative stability of sunflower oil.
Methods: The essence of Bane was added to sunflower oil at concentrations of 200, 400,600,800, and 1,000 ppm. Tertiary Butyl Hydroquinone (TBHQ) was applied as synthetic antioxidant. All samples with the control were stored at 65 ̊C for 20 days. Gas Chromatography-Mass Spectrometry was used for the essence analysis. The 2,2-diphenyl-1-picrylhydrazyl radical scavenging assay, rancimat, p-anisidine value (P-AnVs), and peroxide value (PV) were determined to assess the efficacy of differecnt concentration of essence (200, 400,600,800, and 1,000 ppm). Data were analyzed by Statistical Analysis System (SAS) version 9 Software.
Results: The essential oil yield was 0.1% v/w. The basic components of essence were monoterpene and sesquiterpene hydrocarbons. Synthetic antioxidant had the highest scavenging activity, followed by the mixture sample. PVs were in the range of 19.56-20.73 milliequivalents (meq)/kg for the treated samples after 20 days, while it was 38.74 on the 20th day for the control. For all treatments, PV was increased with increasing storage time. P-AnVs were 8.58-17.14 for stabilized samples and 18.02 for control sample on the 20th day of storage. In all stages, control sample had the highest P-AnV. For all samples, P-AnV increased as a subject of storage time.
Conclusion: P. atlantica (Bane) essential oil had a stabilizing effect on sunflower oil and can be used as a natural antioxidant to stabilize edible oil during storage.

Abstract
Background Methylmalonic aciduria is a rare inherited metabolic disorder with autosomal recessive inheritance pattern. There are still MMA patients without known mutations in the responsible genes. This study aimed to identify mutations in Iranian MMA families using autozygosity mapping and NGS. Methods Multiplex PCR was performed on DNAs isolated from 12 unrelated MMA patients and their family members using 19 STR markers flanking MUT, MMAA, and MMAB genes, followed by Sanger sequencing. WES was carried out in the patients with no mutation. Results Haplotype analysis and Sanger sequencing revealed two novel, mutations, A252Vf*5 and G87R, within the MMAA and MUT genes, respectively. Three patients showed no mutations in either autozygosity mapping or NGS analysis. Conclusion High-frequency mutations within exons 2 and 3 of MUT gene and exon 7 of MMAB gene are consistent with the global expected frequency of genetic variations among MMA patients.

Abstract
Since wound dressing has been considered a promising strategy to improve wound healing, recent attention has been focused on the development of modern wound dressings based on synthetic and bioactive polymers. In this study, we prepared a multifunctional wound dressing based on carboxymethyl chitosan (CMC)/sodium alginate (Alg) hydrogel containing a nanostructured lipid carrier (NLC) in which simvastatin (SIM) has been encapsulated. This dressing aimed to act as a barrier against pathogens, eliminate excess exudates, and accelerate wound healing. Among various fabricated composites of dressing, the hydrogel composite with a CMC/sodium Alg ratio of 1:2 had an average pore size of about 98.44 ± 26.9 μm and showed 707 ± 31.9% swelling and a 2116 ± 79.2 g m-2per day water vapor transfer rate (WVTR), demonstrating appropriate properties for absorbing exudates and maintaining wound moisture. The NLC with optimum composition and properties had a spherical shape and uniform particle size distribution (74.46 ± 7.9 nm). The prepared nanocomposite hydrogel displayed excellent antibacterial activity againstEscherichia coliandStaphylococcus aureusas well as high biocompatibility on L929 mouse fibroblast cells. It can release the loaded SIM drug slowly and over a prolonged period of time. The highest drug release occurred (80%) within 14 d. The results showed that this novel nanocomposite could be a promising candidate as a wound dressing for treating various chronic wounds in skin tissues.

Abstract
Introduction: Measurement of pancreatic beta cell mass in animal models is a common assay in diabetes researches. Novel whole-organ clearance methods in conjunction with transgenic mouse models hold tremendous promise to improve beta cell mass measurement methods. Here, we proposed a refined method to estimate the beta cell mass using a new transgenic Tg(Pdx1-GFP) mouse model and a recently developed free-of-acrylamide clearing tissue (FACT) protocol. Methods: First, we generated and evaluated a Tg(Pdx1-GFP) transgenic mouse model. Using the FACT protocol in our model, we could quantify the beta cell mass and alloxan-induced beta cell destruction in whole pancreas specimens. Results: Compiled fluorescent images of pancreas resulted in enhanced beta cell mass characterization in FACT-cleared sections (2928869±120215 AU) compared to No-FACT cleared sections (1292372±325632 AU). Additionally, the total number of detected islets with this method was significantly higher than the other clearance methods (155.7 and 109, respectively). Using this method, we showed green fluorescent protein (GFP) expression confined to beta cells in Tg(Pdx1-GFP) transgenic. This enhanced GFP expression enabled us to accurately measure beta cell loss in a beta cell destruction model. The results suggest that our proposed method can be used as a simple, and rapid assay for beta cell mass measurement in islet biology and diabetes studies. Conclusion: The Tg(Pdx1-GFP) transgenic mouse in conjunction with the FACT protocol can enhance large-scale screening studies in the field of diabetes.

Abstract
Inflammasomes are multiprotein complexes that represent critical elements of the inflammatory response. The dysregulation of the best-characterized complex, the NLRP3 inflammasome, has been linked to the pathogenesis of diseases such as multiple sclerosis, type 2 diabetes mellitus, Alzheimer's disease, and cancer. While there exist molecular inhibitors specific for the various components of inflammasome complexes, no currently reported inhibitors specifically target NLRP3PYD homo-oligomerization. In the present study, we describe the identification of QM380 and QM381 as NLRP3PYD homo-oligomerization inhibitors after screening small molecules from the MyriaScreen library using a split-luciferase complementation assay. Our results demonstrate that these NLRP3PYD inhibitors interfere with ASC speck formation, inhibit pro-inflammatory cytokine IL1-β release, and decrease pyroptotic cell death. We employed spectroscopic techniques and computational docking analyses with QM380 and QM381 and the PYD domain to confirm the experimental results and predict possible mechanisms underlying the inhibition of NLRP3PYD homo-interactions.

Abstract
Background The lifestyle of the mother during pregnancy can affectthe health of their baby. Since lifestyle change is a sociocultural act and the motivations associated with lifestyle patterns during pregnancy cannot be explained in quantitative studies, a comprehensive study of the lifestyle during pregnancy and factors influencing its patterns was needed to investigate it from different aspects. Thus, the present study aimed to explore ‘mothers’ perceptions and experiences about lifestyle patterns during and after pregnancy and the reasons for adopting these lifestyles. Methods The present study, conducted on 20 pregnant or postpartum women living in Bushehr, Iran, has used a conventional content analysis approach. The purposeful sampling method was used with maximum diversity and continued until data saturation. data were collected through face-to-face, in-depth, semi-structured interviews. Informed consent was obtained from all participants, and assuringthe confidentiality of their information. MAXQDA 10 software was used to analyze the data. Results Four main themes were defined after data analysis; "Being a mother as motivation for adopting a new healthy lifestyle"; "Access to information from media and supports from physicians as facilitators of adopting healthy lifestyle"; "Aspects of lifestyle modifications" and "Durability of healthy lifestyles". When women become pregnant, they feel a responsibility tohave a healthy pregnancy. They care about their fetuses more than themselves, which motivated them to look for the best lifestyle. In this way, access information from mass media and recommendations from professionals (physicians, midwives, and other health care providers) were helpful factors to have a healthy lifestyle, leading to modifying physical, mental, and religious aspects of lifestyle. However, despite reminding the advantages of a healthy lifestyle, these changesshift to a pre-pregnancy lifestyle due to the cessation of support and care provided during pregnancy. Conclusion The study results showed that pregnant women should be motivated to modify their lifestyle andadopt healthy lifestyles. Pregnant women seek to modify their lifestyle because of motherhood responsibility and and having a healthy baby. Access to information and supports from various sources promote a mother’s inner decision to change, leading to modifying different aspects of life. However, these modifications often shift to the pre-pregnancy lifestyle due to cessation of supports and care, despite reminding the benefits of the lifestyle change. Health care providers should consider supportive measures during pregnancy and postpartum.

Abstract
OBJECTIVES The wound healing potential of beta-blocker drugs such as propranolol (PNL) has recently attracted attention. To date, incorporation of PNL into electrospun nanofibrous wound dressing mats has not been tested as a novel topical drug delivery system. Presently, electrospun nanofibrous mats loaded with PNL were fabricated, and their physicochemical properties and wound healing activities were evaluated. MATERIALS AND METHODS Polyvinyl alcohol solutions containing 0, 2% or 4% (wt/vol) PNL were electrospun into mats, and the physicochemical properties and PNL release were evaluated. In vitro biocompatibility of selected PNL-loaded mats was tested in human foreskin fibroblasts and wound healing capability was evaluated in mouse skin wounds. RESULTS The 4% PNL mat had thin fibers (160 nm), convincing porosity (79.5%), and good hydrophilicity (swelling: 89.1%, water contact angle: 42.1°) with little degradability (14.2%). The release of PNL was not in bursts and was best explained by the Korsmeyer-Peppas equation (R2 = 0.96, n = 0.40), suggesting Fickian release. The viability of fibroblasts was 173% on day 5 of incubation with 4% PNL mats, indicating good mat biocompatibility. In vivo treatment for 14 days with 4% PNL mats resulted in wounds with a surface area of only 9% of the original wound area. These wounds had better histopathologic characteristics and were associated with less oxidative stress. CONCLUSION The wound dressing fabricated with 4% PNL showed good potential for wound healing because of a favorable drug release profile from the nanofiber scaffold, and can be considered eligible for further clinical research.

Abstract
Recently, the Organ Procurement and Transplant Network approved a plan to allocate kidneys within 250-nm circles around donor hospitals. These homogeneous circles might not substantially reduce geographic differences in transplant rates because deceased donor kidney supply and demand differ across the country. Using Scientific Registry of Transplant Recipients data from 2016-2019, we used an integer program to design unique, heterogeneous circles with sizes between 100 and 500 nm that reduced supply/demand ratio variation across transplant centers. We weighted demand according to wait time because candidates who have waited longer have higher priority. We compared supply/demand ratios and average travel distance of kidneys, using heterogeneous circles and 250 and 500-nm fixed-distance homogeneous circles. We found that 40% of circles could be 250 nm or smaller, while reducing supply/demand ratio variation more than homogeneous circles. Supply/demand ratios across centers for heterogeneous circles ranged from 0.06 to 0.13 kidneys per wait-year, compared to 0.04 to 0.47 and 0.05 to 0.15 kidneys per wait-year for 250-nm and 500-nm homogeneous circles, respectively. The average travel distance for kidneys using heterogeneous, and 250-nm and 500-nm fixed-distance circles was 173 nm, 134 nm, and 269 nm, respectively. Heterogeneous circles reduce geographic disparity compared to homogeneous circles, while maintaining reasonable travel distances.

Abstract
Background: Different Salvia species have demonstrated anti-proliferative effects on various cancer cells. Owing to the poor literature on the anti-proliferative effects of Salvia species on gastric cancer cells, present study was conducted to determine the anticancer effects of a local Iranian Salvia, Salvia chorassanica, on two different gastric cell lines. Methods: Root, stem and leaf extract of Salvia chorassanica were prepared through maceration method and were then used to treat the AGS and MKN-45 cell lines in different concentrations. MTT assay was employed to determine the toxicity of all the types of extracts on the two studied cell lines. The expression of Bax, Bcl-2, Caspase3, MMP2 and MMP9 genes were determined through reverse transcription Real time PCR (RT-PCR). Results: Bunge and shoot extracts demonstrated toxicity in both cell lines which were more considerable in AGS cells treated with root extract. In contrary to AGS cells, Caspase3 gene was up-regulated in all types of treatment while the MMP2 and MMP9 genes were down-regulated (p-value<0.001). Except of the MKN-45 cells treated with leaf extract, Bax/Bcl-2 expression ratio was decreased in the treatment with all types of Salvia chorassanica extracts (p-value<0.001). Conclusion: Remarkable low IC50 concentration of root extract in MKN-45 cell line is indicating the significant cytotoxicity of Salvia chorassanica against gastric cancer cells. Moreover, gene expression analysis in MKN-45 needs further confirmation on the potential anti-metastatic roles of leaf and root extracts in higher grades of gastric cancer.

Abstract
Background: Oral squamous cell carcinoma (OSCC) is one of the most important types of oral malignancies. DKK gene family members as well as DKK2/4 have critical roles in regulation of Wnt signaling as one of the main determining pathway in oral carcinogenesis. This study aimed to identify promoter methylation status of DKK2/4 genes to provide possible biomarkers for early detection and treatment of OSCC patients. Methods: A case control study was performed on 31 fresh tissues obtained from oral cavity of patients affected by OSCC and 31 fresh corresponding tissues from normal healthy controls in Tehran and, between the years of 2016–2018. Purified DNA from tissue samples was subjected to bisulfite treatment and then methylation specific polymerase chain reaction (MSP-PCR) was carried out on treated DNA samples. Results: DKK4 promoter was methylated in none of OSCC samples while it was methylated in 16.1% of healthy controls. 16.1% of OSCC samples were detected to be semimethylated and 22.6% of healthy normal samples were methylated for DKK2 promoter gene. Meaningful difference was found in DKK4 promoter methylation among OSCC patients and healthy controls. Significant correlation was found between DKK4 promoter methylation and tumor grade. The age of all enrolled samples was demonstrated to have strong effect on promoter methylation of studied genes. Conclusion: Hypomethylation of DKK2 and DKK4 genes in higher grades of OSCC samples may indicate the pivotal role of their expression in tumor cells invasion and progression through modulation of Wnt signaling pathway. Further study required to determine simultaneous expression of those genes and Wnt signaling elements at mRNA and protein levels.

Abstract
Introduction: Coronary artery diseases (CAD) are still among the top causes of death in most populations. The polymorphisms of the cholesteryl ester transfer protein (CETP) gene can influence the risk of CAD through modulating cholesterol metabolism. In this regard, the current study aimed to determine the role of the 2 important CETP gene polymorphisms in CAD patients. Methods: To this end, DNA was extracted from the whole blood of 100 CAD patients and 100 healthy controls and then subjected to polymerase chain reaction-restriction fragment length polymorphism for the genotyping of rs5882 and rs708272 polymorphisms.Results: Based on the results, no meaningful association was found between rs5882 and rs708272 polymorphisms, neither separately nor in combination, and the risk of CAD. However, the risk of CAD significantly increased in male rs5882 polymorphism carriers (P = 0.01). Finally, no significant association was demonstrated between serum high-density lipoprotein levels and the genotypes or alleles of neither rs5882 nor rs708272 polymorphism. Conclusion: Despite the finding regarding the lack of an association between CAD and the studied polymorphisms of the CETP gene, the importance of those variants in CETP protein function and CAD pathogenesis warrants further investigation on larger populations.

Abstract
INTRODUCTION Despite advanced diagnostic and therapeutic techniques, many brain tumors are still diagnosed at high grades and, therefore finding novel molecular markers may assist in early detection and reducing brain tumors-related mortality rate. Owing to the previous reports on the importance of MCPH1 gene in tumorigenesis, the present study was aimed to study the promoter methylation of MCPH1 gene in paired circulating cell-free DNA (cfDNA) and tumor tissues of brain tumor patients. MATERIALS AND METHODS Fourteen fresh paired serum and tumor tissue samples in addition to 18 isolated serum samples were collected from patients affected by different grades of brain tumor. Genomic DNA and cfDNA was isolated from tissue and serum samples using QIAamp DNA Mini Kit Norgen Bioteck Kit, respectively. Methylation DNA immunoprecipitation Real-time polymerization chain reaction (MeDIP-Real-time PCR) was performed on isolated DNA samples using EpiQuik MeDIP Ultra Kit and specific primer pairs. cfDNA quantity was determined through Real-time PCR analysis using specific primer pairs designed for GAPDH gene. RESULTS MCPH1 was methylated in 54% of cfDNA samples which was significantly associated with tumor grade, as well (P-value = 0.02). The methylation rate of MCPH1 was found as 78% in the tissue samples which was meaningfully associated with tumor grade (P-value = 0.03). Moreover, methylation of the MCPH1 gene was consistent in 57% of the same cfDNA and tissue samples. Methylation of MCPH1 gene in neither tumor tissues nor cfDNA was not correlated with age and sex of the patients. DISCUSSION AND CONCLUSION Due to the conformity of methylation of MCPH1 gene in cfDNA and tissue samples in more than half of the enrolled patients, especially in higher grades of tumors, it seems that MCPH1 promoter methylation could be a potential epimarker in not only detection of brain tumors but also in response to chemo- and radiotherapy which warranted further assessment.

Abstract
Background Mothers’ capability for childcare and compatibility with the maternal role represent important challenges in postpartum care. Given the significance of evaluating maternal functioning, and the lack of adequate standard instruments in Iran for this purpose, the present study was aimed at translating and conducting a psychometric assessment of the Barkin Index of Maternal Functioning (BIMF) for Iranian women. Methods The instrument was translated into Persian using the Backward Forward method. The study included 530 women in the postpartum period admitted to healthcare centers in Tabriz, Iran; they were selected through the cluster sampling method. Face, content, and construct (through exploratory and confirmatory analyses) validity were presently examined. Reliability of the questionnaire was determined using the internal consistency and test-retest reliability methods. Results Two factors (mom’s needs and competency), emerged based on exploratory factor analysis. The x2/df ratio was less than 5, and the values of the Root Mean Square Error of Approximation (RMSEA) and the Root Mean Square Residual (RMR) were less than 0.08 and 0.1, respectively, verifying the model validity. Cronbach’s alpha coefficient and Intra-class Correlation Coefficient (ICC) were calculated as 0.88 and 0.85, respectively, indicating reliability. Conclusion The Persian version of the BIMF is a valid and reliable instrument for measuring the postpartum functioning of Iranian mothers.

Abstract
Abstract- Hereditary non-polyposis colorectal cancer (HNPCC) is the most frequent autosomal dominant predisposition for development of colorectal cancer (CRC) caused by germline defects in mismatch repair (MMR) genes. Current study was aimed to find genetic variations in MSH2 and MLH1 genes and their correlation with the serum levels of Carcinoembryonic Antigen (CEA) in seven Iranian HNPCC families. Seven unrelated Iranian families including 11 HNPCC patients and 7 affected family members were selected. They were initially screened for mutations in exons 7 of MSH2 and exon 15 of MLH1 gene through polymerase chain reaction single-strand conformation polymorphism (PCR-SSCP). Positive PCR results were further analyzed through exon sequencing. Serum CEA level was determined using the ELISA test. PCRSSCP was positive in 8 out of 18 patients (44%) for exons 7 of MSH2 gene, whereas two samples (11%) demonstrated to bear a mutation in exon 15 of the MLH1 gene. Sequencing analysis of both amplified exons in positive and negative samples have confirmed no mutation in negative samples while revealed 5 and 7 novel mutations in exons 7 and 15, respectively. The mean serum concentration of CEA had a significant difference between HNPCC patients and their healthy family members. Our results demonstrated that the PCR-SSCP method has high specificity and sensitivity in the first step of mutation screening of HNPCC families. High frequency of novel alterations found in the current assay may revise the mutation screening of MSH2 and MLH1 genes and abet further assessment of their frequency among individual HNPCC patients.

Abstract
Owing to the lack of perfect accuracy and sufficient sample size in previously performed studies on cell-free foetal DNA (cffDNA) for detection of foetal gender through maternal plasma, this study aimed to investigate the efficiency of using two Y-chromosome specific probes in foetal sex determination during first trimester of pregnancy. Five millilitres of whole blood was drawn from 192 pregnant women (10-12 weeks) and was subjected to isolate cffDNA following separation of plasma. TaqMan Real-time PCR was performed on isolated cffDNA using primer pairs and probes specific for SRY, ZFY and β-globin genes. Co-amplification of ZFY and SRY genes was detected in 103 samples confirmed after the birth. Sensitivity and specificity of the test were calculated to be 100%. Further study on larger sample size is required to confirm the reproducibility of the present test in early and non-invasive determination of foetal sex. IMPACT STATEMENT What is already known on this subject? Foetal gender analysis through maternal plasma has been investigated in some cell-free foetal DNA (cffDNA) analysis. However, the detection rate and method of cffDNA analysis were different among various studies. What do the results of this study add? This study introduced a modified simple probe based real time analysis with perfect detection rate. What are the implications of these findings for clinical practice and/or further research? The proposed method can be used as diagnostic test in all laboratories around the world using real-time PCR to non-invasively determine the foetal gender in the initial weeks of pregnancy following confirmation in larger sample size.

Abstract
BACKGROUND Cancer testis antigens (CTAs) are considered cancer bio-markers due to their highly specific expression pattern in human malignancies and near absence from normal somatic tissues. Their specific expression has made them potential targets for early dia-gnosis, assessment of patients prognosis and treatment of cancer in recent years. Lactobacilli are a group of probio-tics with anti-cancer, immunomodulatory and other beneficial features. These bacteria have been shown to alter expression of several cancer-related genes. AIM We investigated the effect of Lactobacillus rhamnosus GG supernatant (LRS) and Lactobacillus crispatus SJ-3C-US supernatant (LCS) on expression of four CTAs (TSGA10, AURKC, OIP5 and AKAP4) in HeLa cell line after synchronization using MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] assay and quantitative real-time polymerase chain reaction. RESULTS LRS and LCS inhibited HeLa cell growth after 24 h as demonstrated by MTT assay. Expressions of all CTAs were down-regulated after treatment with both supernatants. CONCLUSION This study showed the role of Lactobacilli in down-regulation of CTAs genes. Such expression change might be involved in the anticancer effects of these Lactobacilli. The underlying mechanisms of these observations are not clear but epigenetic modulatory mechanisms may participate in this process. Future studies are needed to assess functional roles of Lactobacilli in modulation of other cancer-related genes. Key words: probio-tic - cancer testis antigen - bio-marker - HeLa cell line.

Abstract
Objective APOB-related familial hypercholesterolemia (FH) is the most common hereditary hyperchlosterolemia with
an autosomal dominant pattern. A number of APOB variants are the most important risk factors for hyperchlosterolemia.
APOB is a large glycoprotein that plays an important role in the metabolism of lipoproteins in the human body. Small
changes in the structure and function of APOB can cause major problems in lipid metabolism. Two forms of APOB are
produced by an editing process of gene replication. APOB48 is required for the production of chylomicrons in the small
intestine and APOB100 is essential in liver for the production of very low density lipoprotein (VLDL) and is also a ligand
for LDL receptor (LDLR) that mediates LDL endocytosis.
Materials and Methods In this case-control study, rs693 (in exon 26 of APOB) and rs515135 (5 'end of APOB) single
nucleotide polymorphisms (SNPs) were analyzed in 120 cases of familial hypercholesterolemia and 120 controls. Both
SNPs were genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) where
PCR products were digested with specific restriction enzymes recognising each single nucleotide polymorphism.
Results This study was analyzed by odds-ratio (OR) and its 95% confidence interval (CI) to examine the association of
the two SNPs with familial hypercholostermia susceptibility. Statistical analysis showed that both SNPs were in Hardy-
Weinberg equilibrium.
Conclusion We found no significant relationship between rs515135 and familiar hypercholesterolemia. However,
there was a significant association between the C allele of rs693 and high familial cholesterol levels. Furthermore, it
seems the dominant model of T allele occurrence has a protective role in emergence of disease.

Abstract
Thrombophilia gene variants have been shown to be associated with higher risk of recurrent pregnancy loss (RPL). Due to the role of human platelets antigen 1 (HPA-1) and fibrinogen β chain (FGB) as critical players in the coagulation process, their most important variants including rs5918 T > C and rs1800790 G > A were selected to be studied in women affected by RPL. Three milliliters of peripheral blood were drawn from 110 women with history of at least two consecutive spontaneous abortion and 110 healthy women controls. rs5918 T > C and rs1800790 G > A of HPA-1 and FGB genes, respectively, were selected to be analyzed through polymerase chain reaction-restriction fragment length polymorphism (PCR_RFLP) following DNA isolation using QIAamp DNA Blood Mini Kit. Heterozygote genotype (TC) of HPA-1 gene rs5918 polymorphism was significantly associated with risk of RPL (p-value = 0.02). Although, rs1800790 G > A of FGB gene was not associated with RPL, its combination with rs5918 polymorphism was associated with increased risk of RPL. Owing to the critical roles of FGB and HPA-1 genes in coagulation, and thrombosis and several confinements on the meaningful association between the combination of those polymorphism with risk of RPL, including them in the thrombophilia panel may increase detection rate of hereditary thrombophilia patients. However, further studies with larger sample sizes are required to shed light on the exact role of the studied gene polymorphism, especially rs1800790 G > A of FGB gene variant in pathogenesis of RPL.

Abstract
AIM Methylated DNA immunoprecipitation real-time quantitative polymerase chain reaction (MeDIP-real-time qPCR) has been introduced as noninvasive prenatal test that has shown absolute detection rate in the screening of Down syndrome. Herein, we aimed to propose a novel modification of MeDIP-qPCR and assess its potential to alleviate the overall cost of the test, being used in very early weeks of pregnancy, and develop it to a noninvasive prenatal diagnosis biosensor in future researches. METHODS Cell-free fetal DNA (cffDNA) isolated from 60 pregnant women, including 29 normal and 31 trisomy 21 pregnancies, were analyzed using proposed MeDIP protocol. Enriched methylated DNA sequences were amplified through real-time qPCR using eight fetal-specific primer pairs. The status of samples was determined through the calculation of D-value with the cutoff point of zero. RESULTS The sensitivity and specificity of the MeDIP protocols using nanoparticles were 100% and 100%, respectively. CONCLUSION Remarkable decrease in the price of MeDIP test per each patient would be a reasonable factor to confirm it on larger sample size. Moreover, the high detection rate of screening and the availability of the required instruments around the world make satisfactory reasons to be tested in earlier weeks of pregnancy, thanks to the high sensitivity of gold shell nanoparticles.

Abstract
Accumulation of cholesterol and other atherogenic lipids such as low-density lipoprotein (LDL) in artery wall causes reduction of vessel diameter and artery stenosis. The study of the mass transfer of these large molecules in the wall with considering effective factors on lumen flow and different physiological factors is the subject considered nowadays. In this paper, results of two dimensional and axi-symmetric simulations of three different models of the artery with 60% stenosis under pulsatile blood flow are presented. Filtration velocity of LDL mass transport in the permeable artery wall and shear stress of blood flow are investigated using ADINA software Three different flow models are considered. In the first and second models, the filtration velocity considered as a given parameter and constant in arterial wall boundary, while in third model arterial wall considered as porous wall, the filtration velocity is calculated from pressure difference as an input parameter of the model. The results show that filtration velocity is strongly depend on geometry and it is not constant along the wall, contrary to simplified models. The results of concentration variations in lumen and wall illustrate the increase in near wall LDL concentration or concentration polarization.

Abstract
Objective: Recent advances in non-invasive prenatal diagnosis (NIPD) through cell free fetal DNA (cffDNA) has highlighted cffDNA purification as a critical initial step. Herein, we aimed to compare the efficiency of one proposed protocol with two commercial kits for isolation of cffDNA. Materials and methods: cffDNA was isolated from whole blood of 50 normal pregnancies using one proposed manual protocol compared with QIAamp DNA Blood Mini and Bioneer Kits. Methylated DNA immunoprecipitation real time polymerase chain reaction (MeDIP-Real time PCR) was performed to quantify three fetal specific sequences. Results: Maximum cffDNA quantity was obtained by suggested protocol (248.79 ± 14.07 ng/µl) and the best quality was achieved by Bioneer Kit (OD ratio: 260/280 nm/nm: 1.69 ± 0.09, 260/230 nm/nm: 1.15 ± 0.13) (p < 0.001). Enrichment of fetal specific sequences was significantly higher when proposed protocol was used to isolate cffDNA (p = 0.01). Conclusion: Inhibitory effect of NaI on nucleases and double digestion of DNA associated proteins may be the main reasons behind the superiority of suggested protocol. Significantly higher amplification of fetal specific sequences in suggested protocol would be a strong evidence on recovery of small fetal fragments as demonstrated with its maximum total DNA quantity and amplification in different PCR reactions.

Abstract
OBJECTIVE To evaluate the effect of Cawthorne-Cooksey and Frenkel exercises on balance in patients with multiple sclerosis. DESIGN It was a three-arm parallel randomized controlled trial study. SETTING Outpatient clinic. SUBJECTS Patients with multiple sclerosis. INTERVENTIONS Subjects in the intervention groups completed a 12-week program consisted of Cawthorne-Cooksey or Frenkel exercises. The control group only received routine care. MAIN MEASURES The outcome measure was the Berg Balance Scale. RESULTS Seventy-two patients completed the study. At the end of the intervention, there was a statistically significant improvement in Berg Balance Scale in the Cawthorne-Cooksey group ( n = 24) in comparison with the other two groups ( P = 0.001). In the Frenkel group ( n = 23), the improvement was statistically greater than the changes in the control group ( n = 25), but it did not appear to be clinically significant. The Berg Balance Scale score increased to 8.9 in the Cawthorne-Cooksey group and 2.3 in the Frenkel group, while it decreased to 1.2 in the control group. When comparing inter-group changes, Berg Balance Scale showed significant improvements in favor of the Cawthorne-Cooksey group after the intervention ( P < 0.05). CONCLUSION This study demonstrated that in comparison with Frenkel and the control groups, a program of Cawthorne-Cooksey exercise is more effective in improving balance in patients with multiple sclerosis.

Abstract
Critical roles of epigenomic alterations in the pathogenesis of breast cancer have recently seized great attentions toward finding epimarkers in either non-invasive or semi-non-invasive samples as well as peripheral blood. In this way, methylated DNA immunoprecipitation microarray (MeDIP-chip) was performed on DNA samples isolated from white blood cells of 30 breast cancer patients compared to 30 healthy controls. A total of 1799 differentially methylated regions were identified including SLC6A3, Rab40C, ZNF584, and FOXD3 whose significant methylation differences were confirmed in breast cancer patients through quantitative real-time polymerase chain reaction. Hypermethylation of APC, HDAC1, and GSK1 genes has been previously reported in more than one study on tissue samples of breast cancer. Methylation of those aforementioned genes in white blood cells of our young patients not only relies on their importance in breast cancer pathogenesis but also may highlight their potential as early epimarkers that makes further assessments necessary in large cohort studies.

Abstract
This research aims to determine the usability of the central library websites of medical sciences universities in Iran. This was a descriptive, cross-sectional study which employed a heuristic evaluation method to evaluate the usability of the websites. Three trained evaluators independently examined the 12 library websites from 11 July to 10 September 2013 using Nielsen’s usability heuristics. A list of usability problems was obtained and the severity of identified problems was determined. We identified 668 usability problems. The highest number of problems concerned ‘aesthetic and minimalist design’ (27.1%) and the lowest number concerned the ‘help and documentation’ heuristic (1%). Since the importance of libraries’ websites cannot be understated, the websites should consider the identified problems and attempt to address them.

Abstract
OBJECTIVE Lactobacilli are a group of probiotics with beneficial effects on prevention of cancer. However, there is scant data in relation with the impacts of probiotics in late-stage cancer progration, especially metastasis. The present original work was aimed to evaluate the anti-metastatic and anti-proliferative activity of lactobacillus rhamnosus supernatant (LRS) and lactobacillus crispatus supernatant (LCS) on the human cervical and colon adenocarcinoma cell lines (HeLa and HT-29, respectively). MATERIALS AND METHODS In this experimental study, the anti-proliferative activities of LRS and LCS were determined through MTT assay. MRC-5 was used as a normal cell line. Expression analysis of CASP3, MMP2, MMP9, TIMP1 and TIMP2 genes was performed by quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR), following the cell synchronization. RESULTS Supernatants of these two lactobacilli had cytotoxic effect on HeLa, however LRS treatment was only effective on HT-29 cell line. In addition, LRS had no side-effect on normal cells. It was shown that CASP3 gene expression has been reduced after treatment with supernatants of two studied lactobacilli. According to our study, LRS and LCS are efficacious in the prevention of metastasis potency in HeLa cells with decreased expression of MMP2, MMP9 and increased expression of their inhibitors. In the case of HT-29 cells, only LRS showed this effect. CONCLUSION Herein, we have demonstrated two probiotics which have anti-metastatic effects on malignant cells and they can be administrated to postpone late-stage of cancer disease. LRS and LCS are effective on HeLa cell lines while only the effect of LRS is significant on HT-29, through cytotoxic and anti-metastatic mechanisms. Further assessments are required to evaluate our results on the other cancer cell lines, in advance to use these probiotics in other extensive trial studies.

Abstract
Background: Green tea is one of the most popular beverages in the world. It is believed to have beneficial effects in the prevention and treatment of many diseases, one of which is nonalcoholic fatty liver disease (NAFLD). The present study investigated the effects of consumption of green tea in NAFLD patients. Methods: This study was a double-blind, placebo-controlled, randomized clinical trial. Ultrasonography was used to diagnose fatty liver in patients with alanine aminotransferase (ALT) >31 mg/dl and 41 mg/dl and aspartate aminotransferase (AST) >31 mg/dl and 47 g/dl in women and men, respectively and without other hepatic diseases. A total of 80 participants (20–50 years) with NAFLD were randomly allocated into two groups to receive either green tea extract (GTE) supplement (500 mg GTE tablet per day) or placebo for 90 days. At baseline and at the end of the intervention weight, serum ALT, AST, and alkaline phosphatase (ALP) were measured in fasting state, and dietary data were collected at baseline and end of the study. Results: Green tea group showed significant reductions in ALT and AST levels after 12 weeks period (P < 0.001). The placebo group showed a reduction in ALT and AST levels at the end of the study, but it was no significant. ALP levels showed significant reductions in both groups after 12 weeks period (P < 0.001). Conclusions: According to the findings of this study, GTE supplementation decrease liver enzymes in patients with NAFLD. It can be claimed that GTE prescribed can be considered as a treatment to improve serum levels of liver enzymes in NAFLD patients.

Abstract
Introduction: Phenylketonuria (PKU) is an autosomal recessive inborn error of phenylalanine metabolism, which is caused by mutation in phenylalanine hydroxylase (PAH) gene. Most of the PAH mutations are missense mutations (67%), which are followed by small or large deletions (13%). Case Presentation: We reported a patient with classic PKU and his parents harboring a large deletion in exon 3 (EX3del4765) of PAH gene. This is the first case report of EX3del4765 in Asian patients with PKU. Conclusions: This finding may help improve early detection, differential diagnosis, genetic counseling, and even treatment of patients with PKU.

Abstract
BACKGROUND Non-organic failure to thrive (NFTT) is the most common cause of failure to thrive (FTT) which is attributed to inadequate nutrition due to economic factors or parental neglect . NFTT can lead to a vicious cycle of poor and inadequate eating and severity of anemia. The aim of this study was to determine the hematological indices in children with NFTT. MATERIALS AND METHODS In a cross sectional case control study, iron status and blood indices of forty five aged 6-60 months children with NFTT were evaluated and compared with 45 healthy control children (with matching of age and sex). RESULTS In this study, the prevalence of anemia was 48.9% in NFTT compared to 11.4% in the control group (p<0.001). Microcytic anemia was significantly more prevalent among the subjects than the controls (77.8% versus 27.3%; p<0. 001). The serum iron level was 73.2 and 62.8 mcg/dl for the case and control groups (P=0.29). The ferritin level in the study group was 29.8 versus 35.47 ng/ml in the control group (p=0.227). The prevalence of iron deficiency anemia among children with mild, moderate, and severe underweight was 44.4%, 45.5%, and 48%, respectively. The highest prevalence of iron-deficiency anemia was seen between age group of 12 and 24 months (p<0.05). CONCLUSION Based on the results of this study, a correlation between malnutrition and anemia was found. However, further studies are needed to assess and confirm the current outcomes.

Abstract
Ataxia telangiectasia mutated (ATM) is a key gene in DNA double-strand break (DSB), and therefore, most of its disabling genetic alterations play an important initiative role in many types of cancer. However, the exact role of ATM gene and its epigenetic alterations, especially promoter methylation in different grades of brain tumors, remains elusive. The current study was conducted to query possible correlations among methylation statue of ATM gene, ATM/ retinoblastoma (RB) protein expression, D1853N ATM polymorphism, telomere length (TL), and clinicopathological characteristics of various types of brain tumors. Isolated DNA from 30 fresh tissues was extracted from different types of brain tumors and two brain tissues from deceased normal healthy individuals. DNAs were treated with bisulfate sodium using DNA modification kit (Qiagen). Methylation-specific polymerase chain reaction (MSP-PCR) was implicated to determine the methylation status of treated DNA templates confirmed by promoter sequencing. Besides, the ATM and RB protein levels were determined by immunofluorescence (IF) assay using monoclonal mouse antihuman against ATM, P53, and RB proteins. To achieve an interactive correlation, the methylation data were statistically analyzed by considering TL and D1853N ATM polymorphism. More than 73% of the brain tumors were methylated in ATM gene promoter. There was strong correlation between ATM promoter methylation and its protein expression (p < 0.001). As a triangle, meaningful correlation was also found between methylated ATM promoter and ATM protein expression with D1853N ATM polymorphism (p = 0.01). ATM protein expression was not in line with RB protein expression while it was found to be significantly correlated with ATM promoter methylation (p = 0.01). There was significant correlation between TL neither with ATM promoter methylation nor with ATM protein expression nor with D1853N polymorphism. However, TL has shown strong correlation with patient's age and tumor grade (p = 0.01). Given the important role of cell cycle checkpoint proteins as well as RB and ATM in TL and cancer evolution, further assessment is warranted to shed more light on the pathway linking the telomere instability to tumor progression. High ATM methylation rate in brain tumor patients could open a new avenue toward early screening and cancer therapy.

Abstract
Objective Multiple sclerosis (MS) is one of the leading neurodegenerative causes of
physical disability world-wide. Genetic aberrations of autoimmunity pathway components
have been demonstrated to significantly influence MS development. Cluster of Differentiation 58 (CD58) is pertained to a group of genes which had been assayed in several recent
association studies. Given the significance of CD58 in modulation of T regulatory cells
that control autoimmune responses, the present study was conducted to investigate the
frequency of rs12044852 polymorphism and its effect on the outcome of interferon beta
(IFN-β) therapy in a subset of Iranian MS patients.
Materials and Methods Two hundred MS patients and equal number of healthy
controls were recruited to be genotyped in an experimental case-control based study
through polymerase chain reaction using specific sequence primers (PCR-SSP). Relapsing remitting multiple sclerosis (RRMS) patients administered IFN-β therapy were
followed up with clinical visits every three months up to two years. The mean of multiple sclerosis severity score (MSSS) and expanded disability status scale (EDSS)
were measured to monitor the change in severity of MS in response to IFN-β therapy.
Pearson’s Chi-square and analysis of variance (ANOVA) tests were the main statistical methods used in this study.
Results Strong association was found between the CC genotype and onset of MS
(p=0.001, OR=2.22). However, there was no association between rs12044852 and
various classifications and severity of MS. Pharmacogenetics-based analysis indicated that carriers of CC genotype had the highest MSSS score compared to others,
implying a negative impact of rs12044852 on response to IFN-β therapy.
Conclusion Taken together, our findings revealed the critical effect of rs12044852 polymorphism of CD58 on the progression of MS disease. This indicates that genotyping of
MS patients may expedite achieving personalized medical management of MS patients.

Abstract
OBJECTIVE Celiac disease (CD) is developed via autoimmune reactions against gluten which is mainly found in grains. Although HLA DQB1 locus is the most important genetic susceptibility to CD, some other variants such as A49G and G1359T of CTLA4 and CD14 genes respectively have been proposed as CD predisposing genetic factors in many vari- ous studies. We aimed to assess possible roles of A49G and G1359T polymorphisms in CD susceptibility in the Iranian population. MATERIALS AND METHODS In this case-control, one hundred CD patients and 100 healthy matched controls with average age of 30-33 years were selected. They were genotyped for both A49G and G1359T polymorphisms using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). RESULTS There was no association between genotypes of A49G variant of CTLA4 and risk of CD (p<0.05). The G1359T polymorphism of CD14 gene also did not show any significant association with risk of CD among the studied population. However, patients with CD14 T/T genotype were more classified in the severe form (Marsh III) of CD, showing border line significance (p<0.05). CONCLUSION No association was identified between the combination of 1359T and A49G alleles with risk of CD. These lacks of association could be due to small sample size and considering further studies in various populations and ethnicities seems to be required.

Abstract
Breast cancer (BC) is the most common cancer of women all over the world. BRCA1 and BRCA2 gene mutations comprise the most important genetic susceptibility of BC. Except for few common mutations, the spectrum of BRCA1 and BRCA2 mutations is heterogeneous in diverse populations. 185AGdel and 5382insC are the most important BRCA1 and BRCA2 alterations which have been encountered in most of the populations. After those Ashkenazi founder mutations, 300T>G also demonstrated sparse frequency in African American and European populations. This review affords quick access to the most frequent alterations among various populations which could be helpful in BRCA screening programs.

Abstract
Ten patients (nine males, one female), seen at the Asir Central Hospital of South-Western Saudi Arabia with proven traumatic diaphragmatic hernia between 1987 and 1997, were reviewed retrospectively. The mean age was 29.6 years, range 5 to 50 years. Chest pain and vomiting were the commonest symptoms. Blunt trauma (road traffic accident--5, fall from height--1, (accounted for 60% of the cases) while gunshot wound and stab wounds were the causes in two patients each. The chest radiograph suggested the diagnosis in all the cases. Barium meal (in two patients) and barium enema (in two patients) complemented the diagnosis. Computed tomography (CT) scan was done in only one patient. Thoracotomy (in 2 patients), laparotomy (in 5 patients) and thoraco-laparotomy (in 3 patients) were the surgical approaches to management. Common herniated organs were liver, stomach, spleen and large bowel. The injuries were on the left side in seven patients and on the right side in three cases. Immediate surgical repair was done in four patients while it was done two days to four years later in others. Complications were minimal and there was only one death.
