Abstract
OBJECTIVES Chronic sinusitis with polyposis (CSWP) is associated with high direct and indirect annual costs. This condition affects several aspects of daily life, and CSWP patients usually suffer from decreased quality of life (QOL). Treatment with functional endoscopic sinus surgery (FESS) is reported to improve the QOL of patients with CS. Here we evaluated the factors that affected QOL improvement in CSWP patients who were candidates for FESS. METHODS All patients with CSWP who were treated at the Imam Khomeini Hospital Complex in Tehan, Iran that were candidates for FESS were recruited. Patients with systemic or neurologic diseases that could affect their QOL were excluded. Clinical signs were recorded before and after FESS using the sinonasal outcome test (SNOT-22) and QOL questionnaires. The patient's history of allergic rhinitis, aspirin sensitivity, asthma and smoking was recorded. QOL and associations with clinical features were evaluated within twelve months after FESS. RESULTS The study included 47 patients with a mean age of 39.5 +/- 15.4 years (61.7% women). FESS resulted in significant improvements in QOL based on the SNOT-22 and QOL questionnaires (p = 0.0001 for both). Septal deviation was the only single characteristic that was significantly associated with QOL improvements. CONCLUSION FESS significantly improved the QOL of patients with CSWP. However, patients with septal deviation benefited the most from FESS.

Abstract
BACKGROUND Accelerated partial breast irradiation via interstitial balloon brachytherapy is a fast and effective treatment method for certain early stage breast cancers however skin, chest wall and Lung doses are correlated with toxicity in patients treated with breast brachytherapy. OBJECTIVE To investigate the percentage of the dose received by critical organ (skin), thermoluminescence detector was used in MammoSite brachytherpy and the ability to control skin dose between MammoSite and MultiCatheter brachytherapy was compared with each other. METHOD Dosimetry is carried out using a female-equivalent mathematical chest phantom and Ir-192 source for brachytherapy application. RESULTS Our initial results has shown good agreement with surface doses between those calculated from the treatment planning results and those measured by the thermoluminescence detector. The mean skin dose for the experimental dosimetry in MammoSite was 2.3 Gy (56.76% of prescription dose). CONCLUSION The results show that the MultiCatheter method is associated with significantly lower mean skin and chest wall dose than is the MammoSite. The MultiCatheter technique is quite flexible and can be applied to any size of breast or lumpectomy cavity, But in MammoSite technique, verification of balloon symmetry, balloon/cavity conformance and overlying skin thickness is essential to assure target coverage and toxicity avoidance.

Abstract
Recent advances in the sequencing technologies have provided a handful of RNA-seq datasets for transcriptome analysis. However, reconstruction of full-length isoforms and estimation of the expression level of transcripts with a low cost are challenging tasks. We propose a novel de novo method named SSP that incorporates interval integer linear programming to resolve alternatively spliced isoforms and reconstruct the whole transcriptome from short reads. Experimental results show that SSP is fast and precise in determining different alternatively spliced isoforms along with the estimation of reconstructed transcript abundances. The SSP software package is available at http://www.bioinf.cs.ipm.ir/software/ssp.

Abstract
Abstract
Radioyttrium (containing 86Y, 87Y and 88Y) was produced by irradiating
a natSrCO3 target with 15 MeV proton beam at a current of 30 µA for
12 min. A synthesized ion imprinted (IIP) and control polymer (CP) nanoparticles as sorbents were used for the
separation of radioyttrium from strontium. The sorbents were characterized by Fourier Transform Infra-red spectroscopy (FT-IR),
Scanning Electron Microscopy (SEM), Energy-Dispersive X-ray spectroscopy (EDX), Thermogravimetric analysis (TGA) and Surface
area analysis. Effect of various parameters such as pH, mass sorbent, nature and volume of eluent were investigated on the
percent extraction of radioyttrium ion using IIP and CP particles. Chemical and radionuclidic purity were determined by ICP-AES
and HPGe detector gamma-ray spectrometry, respectively. The radioyttrium recovery yield was 99.5% and the stable Sr
content in the final product was estimated to be 4.5 µg mL−1. In conclusion, the suggested method in this
manuscript can be used for the production of other 86/87Y radionuclides.

Abstract
Abstract
This study aims to determine AAPM TG-60 dosimetric quantities in regions surrounding the 103Pd stent wall by MCNP5 Monte Carlo code. The Palmaz-Schatz stent was modeled by a hollow cylinder of 17.89mm length (2mm diameter) with net surface very similar to real stent. The Dose deposited per photon (Gy), relative dose, Anisotropy function, F(r,θ), and radial dose function, gL(r), were described at AAPM TG-60 protocol were generated from these values and listed in tabular format. For benchmarking, the relative dose values were verified with TG-43 and EGS4 code results at identical conditions, relative to the radial distances from surface of the stent. There were noticeable results. These physical dosimetric parameters can be used in future treatment planning systems for IVBT.

Abstract
Abstract
Gold-198 (βmax=0.96MeV (98.6%), γmax=0.412MeV (95.5%) and T1/2=2.7 days) is a well-known therapeutic beta emitter in the field of nuclear medicine, and is being used for the treatment of many different cancers. In the present study, the Bremsstrahlung exposure induced by 198Au in different human tissues, DNA and RNA has been calculated. The specific Bremsstrahlung constant (ΓBr), Probability of energy loss by beta during Bremsstrahlung emission (PBr) and Bremsstrahlung activity (Arelease)Br were estimated. We strongly recommend these parameters should be considered in absorbed dose calculations of radionuclide therapy via 198Au.

Abstract
Abstract
85Sr, having a half-life of 64.8 d, is an important radionuclide in nuclear medicine diagnostic and endotherapy. The ALICE/ASH code was used to calculate excitation functions for proton, alpha and deuteron induced on various targets that lead to the production of 85Sr radioisotopes using intermediate energy accelerators. Recommended thickness of the targets according to SRIM code was premeditated. The application of those data, particularly in the calculation of integral yields, is discussed and theoretical integral yields for different reactions were computed. To consider precision of ALICE/ASH code calculations, experimental excitation functions in several decay channels was compared with ALICE/ASH code data. The 85Rb(p, n)85Sr process was determined as most interesting one due to radionuclidic purity. The ALICE/ASH code predicts a maximum cross-section of about 798 mb at 11 MeV for this reaction.

Abstract
Abstract
Derived from AAPM task group No. 60/149 protocol, applicable in treatment planning In this study, the two-dimensional dose distributions in water for a 32P intravascular brachytherapy stent have been calculated. The pure beta emitter source 32P which has been coated on Palmaz-Schatz stent is discussed. The dosimetric parameters required by the AAPM TG-60/149 formalism are discussed and calculated. Version 5 of the (MCNP) Monte Carlo radiation transport code was used to calculate the dosimetry parameters around the source. The Monte Carlo calculated dose rate at the reference point is found to be 2.8 Gy/μCi. Also in this study, the geometry function, G(r,θ), radial dose function, g(r), and the anisotropy function, F(r,θ), have been calculated at distances from 1.8 to 9 mm. The results of these calculations have been compared with other published calculated and measured values for an actual same source. High dose variants were visible near the 32P stent surface, but these values decreased with depth in water rapidly. There is an acceptable agreement between the calculated data in this study and other published data for the same source, which validate our simulations method.

Abstract
Excitation functions for protons induced on 85/natRb targets that lead to the production of 85Sr radioisotopes using TALYS 1.0 and ALICE/ASH codes were calculated. Rubidium chloride deposition on copper substrate was carried out via sedimentation method in order to produce Strontium-85. 520 mg RbCl, 208 mg ethyl cellulose (EC) and 4 mL acetone were used to prepare a layer of enriched rubidium chloride of 11.69 cm2 area and 62.2 mg · cm−2 thickness. The deposited target was irradiated at 20 A current and 15 MeV proton beam for 10 h and no degradation was observed. The 85Sr production yield was 1.4 MBq/mA · h. The target material was dissolved by 50 mL acetone. Dissolved Strontium-85 was separated from rubidium by Chelex 100 ion exchanger.

Abstract
Abstract
For roughly 25 years, 125I sources have been used in the treatment of various malignant diseases such as prostate cancer. Three new brachytherapy sources, IR01-125I, IR02-125I and IR03-125I, have been developed and are designed for permanent implant application. The Monte Carlo radiation transport code version MCNP 5 was used to calculate the dosimetry parameters around the sources in accordance with the updated report of the American Association of Physicists in Medicine (AAPM), Task Group No. 43. For each source, the dose rate constant Λ, the radial dose function gL(r), and the anisotropy function F(r, θ), were obtained. The results indicated a dose rate constant of 0.932 ± 0.01, 0.934 ± 0.01 and 0.939 ± 0.01 Gy h−1 U−1 for the IR01-125I, IR02-125I and IR03-125I sources respectively. With the goal of determining an optimal design for a 125I source, each seed's parameters were compared with other seeds. In this study, the optimal source IR03-125I provides the most isotropic dose distribution in water. Finally, the results for optimal source were compared with published results for those of other commercial sources.

Abstract
Abstract
Silver electrodeposition on gold layer was carried out by the alkaline plating baths to produce cadmium-109 via natAg(p, n)109Cd nuclear reaction. Gold was electrodeposited on copper backing in the beginning; the bath content consisted of 17.7 gl−1 KCN, 6.6 gl−1 Au, 6.6 gl−1 K2CO3 and 3.3 gl−1 Na2CO3 while acidity and temperature of the bath adjusted at 10 and 45°C respectively. A DC current density of ca 2.08 mA · cm−2 was used to electroplate gold. A gold layer of 63 μm thickness with suitable morphology was obtained after the electrodeposition. Silver was electrodeposited on the gold layer with 100% efficiency using a cyanide bath. The silver target was irradiated with 15 MeV proton beam and current of 150 μA; the 109Cd production yield was 2.0 μCi/μA · h (0.074 MBq/μA · h). The target material was dissolved by 14 M HNO3. Cadmium-109 in the dissolved target solution was separated from silver by evaporation process. Cadmium recovered with more than 88% efficiency involved non-detected silver impurity.

Abstract
Abstract
89Zr is an important positron-emitting radionuclide for positron emission tomography (PET) and used in the field of tumor diagnostics, tumor therapy and the investigation of the bio-kinetic. The ALICE-91 and TALYS-1.0 codes were used to calculate excitation function for proton, alpha, deuteron and neutron induced on various targets that lead to the production of 89Zr radioisotopes using intermediate energy accelerators. Requisite thickness of the targets was obtained by SRIM code. The 89Zr production yield was evaluated using excitation function and stopping power. For the 89Y(p, n)89Zr reaction, the calculation data were compared with the experimental data. The 89Y(p, n)89Zr process was determined as most interesting one due to radionuclide purity. The ALICE-91 and TALYS-1.0 codes predict a maximum cross-section of about 939.86 mb at 15MeV and 860 mb at 13MeV respectively for this reaction.

Abstract
Abstract
101mRh is one of such radionuclides that has been considered as a potential candidate for targeted radiotherapeutic use, due to its nuclear decay and chemical properties. Electrodeposition of rhodium metal on a copper backing was performed in acidic sulphate. The target was bombarded with a current intensity of 120 μA (Ep = 29 → 25 MeV) for 30 min (60 μAh). Radiochemical methods were investigated to optimize the production of no-carrier-added 101Pd/101mRh. The use of a cyclotron target with radiochemical processes (i.e. electrodeposition, electrodissolution and ion-exchange column chromatography) were carried out to produce this radionuclide in high-specific activity and radiochemical form suitable for radiopharmaceutical syntheses.

Abstract
BACKGROUND Contamination of water by toxic chemicals has become commonly recognized as an environmental concern. Based on our clinical observation in Mashhad, northeastern Iran, many people might be at risk of exposure to high concentrations of toxic heavy metals in water. Because wastewater effluents as well as water wells have been commonly used for irrigation over the past decades, there has been some concern on the toxic metal exposure of crops and vegetables irrigated with the contaminated water. OBJECTIVE To measure the concentrations of mercury, lead, chromium, cadmium, arsenic and aluminium in irrigation water wells and wastewaters used for agriculture in Mashhad, northeastern Iran. METHODS 36 samples were taken from irrigation water wells and a wastewater refinery in North of Mashhad at four times--May 2008, March 2009, and June and July 2010. Atomic absorption spectrometry was used to measure the concentration of toxic metals. Graphite furnace was used for the measurement of lead, chromium, cadmium and aluminum. Mercury and arsenic concentrations were measured by mercury/hydride system. RESULTS Chromium, cadmium, lead and arsenic concentrations in the samples were within the standard range. The mean±SD concentration of mercury in irrigation wells (1.02±0.40 μg/L) exceeded the FAO maximum permissible levels. The aluminum concentration in irrigation water varied significantly from month to month (p=0.03). All wastewater samples contained high mercury concentrations (6.64±2.53 μg/L). CONCLUSION For high mercury and aluminum concentrations, the water sources studied should not be used for agricultural use. Regular monitoring of the level of heavy metals in water and employing the necessary environmental interventions in this area are strongly recommended.

Abstract
BACKGROUND Acne formation is a common dermatological problem which, if left untreated, may lead to severe facial scars, a consideration that may be particularly important for patients who seek cosmetic surgery. Postrhinoplasty acne development has not yet been discussed in the literature. We therefore decided to evaluate the occurrence of acne in nasal plastic surgery in a case-control study. SUBJECTS & METHODS One hundred and twenty patients were selected for this case-control study and were then assigned to case and control groups, each consisting of 60 patients. None of the participants was a known case of acne and those with any specific skin condition were excluded from the study. The cases were patients whose external nasal structures had been affected by the procedure; the control group consisted of matched patients who were candidates for closed septoplasty. After the operation, acne formation was evaluated in all participants and a comparison was made between cases and controls looking at the surgical method employed, and at the patients' personal and family backgrounds. RESULTS Twelve patients, all from the case group, developed postsurgical acne; all these patients had undergone open rhinoplasty. Age, gender, family history for acne and recent medication use prior to the surgery showed no significant correlation with acne formation. CONCLUSION The incidence of acne after nasal plastic surgery was significantly higher than in the control group, especially when the method of surgery was open rhinoplasty.

Abstract
BACKGROUNDS Helicobacter pylori colonize the gastric mucosa of half of the world's population. Although it is classified as a definitive type I carcinogen by World Health Organization, there is no effective vaccine against this bacterium. H. pylori evade the host immune response by avoiding toll-like detection, such as detection via toll-like receptor-5 (TLR-5). Thus, a chimeric construct consisting of selected epitopes from virulence factors that is incorporated into a TLR-5 ligand (Pseudomonas flagellin) could result in more potent innate and adaptive immune responses. MATERIALS AND METHODS Based on the histocompatibility antigens of BALB/c mice, in silico techniques were used to select several fragments from H. pylori virulence factors with a high density of B- and T-cell epitopes. RESULTS These segments consist of cytotoxin-associated geneA (residue 162-283), neutrophil activating protein (residue 30-135) and outer inflammatory protein A (residue 155-268). The secondary and tertiary structure of the chimeric constructs and other bioinformatics analyses such as stability, solubility, and antigenicity were performed. The chimeric construct containing antigenic segments of H. pylori proteins was fused with the D3 domain of Pseudomonas flagellin. This recombinant chimeric gene was optimized for expression in Escherichia coli. The in silico results showed that the conserved C- and N-terminal domains of flagellin and the antigenicity of selected fragments were retained. DISCUSSION In silico analysis showed that Pseudomonas flagellin is a suitable platform for incorporation of an antigenic construct from H. pylori. This strategy may be an effective tool for the control of H. pylori and other persistent infections.

Abstract
Negative control of clavulanic acid by phosphate in Streptomyces clavuligerus DSM 738 suggests that a pho regulon may exist in this bacterium. S. clavuligerus PhoP was expressed with a C-terminal His-tag in Escherichia coli and purified. Binding of PhoP-His 6 to promoter fragments of phoRP/phoU and pstS was demonstrated in gel retardation experiments. These fragments contained direct 11 bp repeats resembling PHO boxes. The tentative consensus sequence, GKTCRHBBNSV, was used to search other potential PhoP target genes in the genomic sequence of S. clavuligerus. In total, the putative PHO binding sequence was found in promoter regions of 31 S. clavuligerus genes. Binding of PhoP- His 6 to the PHO box present in the promoter region of the phosphate transporter gene SSCG_07547 of S. clavuligerus was demonstrated. Furthermore, it was shown by real time PCR that decreased concentrations of phosphate do affect increased expressions of genes to which PhoP binds. These findings confirm that a pho regulon exists in S. clavuligerus.

Abstract
In current computational biology, assigning a protein domain to a fold class is a complicated and controversial task. It can be more challenging in the much harder task of correct identification of protein domain fold pattern solely through using extracted information from protein sequence. To deal with such a challenging problem, the concepts of hyperfold and interlaced folds are introduced for the first time. Each hyperfold is a set of interlaced folds with a centroid fold. These concepts are used to construct a framework for handling the uncertainty involved with the fold classification problem. In this approach, an unknown query protein is assigned to a hyperfold rather than a single fold. Ten different sequence based features are used to predicting the correct hyperfold. This architecture is featured by the Dempster-Shafer theory of evidence through the bodies of evidence and Dempster's rule of combination to combine the hyperfolds. The classification architecture thus developed was applied for identifying protein folds among the 27 famous SCOP fold patterns from a stringent well-known dataset. Compared with the existing predictors tested by the same benchmark dataset, our approach might achieve the better results.

Abstract
It is confirmed that pharmacological attenuation of glial cells can alleviate neuropathic pain by lowering proinflammatory cytokine expression. The present study tries to confirm that post-injury administration of glia inhibitor, minocycline, can attenuate the neuropathic pain symptoms and improves the efficacy of morphine anti-nociception in chronic constriction injury (CCI). Male Wistar rats (230-270 g) underwent surgery for induction CCI model of neuropathy. For assessment of the thermal hyperalgesia and mechanical allodynia after CCI induction, morphine (2.5, 5, 7.5, 10 and 15 mg/kg; s.c.) and saline were administered on post-operative days (PODs) 0, 6 and 14. Hargreaves and Von-Frey tests were performed before and 30 min after morphine administration, respectively. The results showed significant decrease in antinociceptive effect of morphine on POD 6 compared to POD 0 only at the dose of 5 mg/kg. On the other hand, on POD 14 the antinociceptive effect of morphine (5, 7.5, 10 and 15 mg/kg) significantly decreased in comparison with POD 0. In another set of experiments, animals received minocycline (10, 20 and 40 mg/kg; i.p.) for eight days from POD 6 to 13 and then the antinociceptive effect of single dose of morphine 5 mg/kg was tested on POD 14. Behavioral tests showed that minocycline (40 mg/kg) could effectively attenuate the thermal hyperalgesia and mechanical allodynia on POD 13. Moreover, minocycline (40, 20 mg/kg) improved the anti-hyperalgesic, and minocycline (40 mg/kg) improved the anti-allodynic effects of morphine 5 mg/kg on POD 14. It seems that the reduction of antinociceptive effect of morphine after CCI may be mediated through glia activation. Modulation of glial activity by minocycline can attenuate CCI-induced neuropathic pain. It is also shown that repeated post-injury administration of minocycline improves the antinociceptive effect of morphine in neuropathic pain.

Abstract
Gene expression is the main cause for the existence of various phenotypes. Through this procedure, the information stored in DNA rises to the phenotype. Essentially, gene expression is dependent upon the successful binding of transcription factors (TFs) - a specific type of proteins - to explicit positions in its upstream, TF binding sites (TFBSs). Unfortunately, finding these TFBSs is costly and laborious; therefore, discovering TFBSs computationally is a significant problem that many researches endeavor to solve. In this paper, a new TFBS discovery method is presented by considering known biological facts about TFBSs. The input to this method includes sequences with arbitrary lengths and the output comprises positions that tend to be TFBS. Through the application of previous methods along with a method that focuses on biological and simulated datasets, it is shown that this method achieves higher accuracy in discovering TFBSs.

Abstract
BACKGROUND The impact of the metabolic syndrome among populations in the Middle East region is unknown; we therefore examined the association between the syndrome and the risk of ischemic heart disease (IHD) in an Iranian population. METHODS AND RESULTS The Isfahan Cohort Study (ICS) prospectively followed 6146 Iranian people (51.8% women, aged 35-75 years) from three cities and their rural districts who were initially free of ischemic heart disease. During the 5 year follow-up, 209 (56% men) cases of ischemic heart disease were detected. The metabolic syndrome was defined by the modified criteria of the National Cholesterol Education Program Adult Treatment Panel III (NCEP/ATPIII). End points were defined as fatal and nonfatal myocardial infarction, sudden cardiac death and unstable angina. A clear dose-response relationship was found between the number of metabolic risk factors and the incidence of IHD, with the hazard ratios increasing dose-dependently from 1.72 (95% CI 0.86-3.46) for only one to 1.97 (1.00-3.90), 2.85 (1.45-5.58) and 4.44 (2.25-8.76) for 2, 3 and ≥4 metabolic syndrome component respectively, relative to those with no component. The adjusted hazard ratio (95% CI) associated with the metabolic syndrome was 1.58 (1.06-2.35) in men and 1.72 (1.08-2.74) in women for IHD. The contribution of metabolic syndrome to the IHD risk was particularly strong among smokers although there was no significant interaction. CONCLUSIONS The metabolic syndrome by NCEP/ATPIII definition is a major determinant of ischemic heart disease in this middle-aged Iranian population, especially among smokers.

Abstract
Phloridzin is the specific and competitive inhibition of sodium/glucose cotransporters in the intestine (SGLT1) and kidney (SGLT2). This property which could be useful in the management of postprandial hyperglycemia in diabetes and related disorders. Phloridzin is one of the dihydrochalcones typically contained in apples and in apple-derived products. The effect of phloridzin orally doses 5, 10, 20 and 40 mg/kg body weight on diabetes was tested in a streptozotocin-induced rat model of diabetes type 1. From beneficial effect of this compound is significant reduction of blood glucose levels and improve dyslipidemia in diabetic rats. As a well-known consequence of becoming diabetic, urine volume and water intake were significantly increased. Administration of phloridzin reduced urine volume and water intake in a dose-dependent manner. Phloretin decreases of food consumption, as well as a marked lowering in the weight. In conclusion, this compound could be proposed as an antihyperglycemic and antihyperlipidemic agent in diabetes and potential therapeutic in obesity.
