Abstract
Background Renin-angiotensin system (RAS) is prominently associated with renal pathophysiology in postmenopausal women. Long non-coding RNAs (lncRNAs) H19, GAS5, MIAT, and Rian have been linked to the pathogenesis of renal injury. Aims This study aimed to evaluate the beneficial effects of daidzein on unilateral ureteral obstruction (UUO) induced-renal injury in ovariectomized (OVX) rats through interaction with angiotensin AT1, Mas receptors, and lncRNAs. Methods 84 female rats were ovariectomized (OVX) two weeks before performing obstruction of the left kidney ureter (UUO). The animals were then randomly divided into four main groups (n=21): Sham+DMSO, UUO+DMSO, UUO+17β-Estradiol (E2) (positive control), and UUO+daidzein. Each main group comprised three subgroups (n=7) and were treated with saline, A779 (MasR antagonist), or losartan (AT1R antagonist) for 15 days. On day 16, the animals were euthanized, and the left kidneys were harvested for histopathology and lncRNAs expression assays. Results UUO significantly increased kidney tissue damage score (KTDS) in the UUO rats, increased the expression of H19 and MIAT, and decreased the expression of GAS5 and Rian. Daidzein alone and in co-treatment with losartan or A779 reversed these effects. Daidzein with 1 mg/kg dose was more effective than E2. Conclusion Daidzein alone and in co-treatment with A779 and losartan improved renal injury in UUO rats and recovered dysregulated expression of UUO-related lncRNAs through modulating MasR and AT1R receptors, associating with modulation of the expression of lncRNAs. Daidzein could be considered a renoprotective phytoestrogen substitute for E2 therapy in postmenopausal women suffering from renal diseases.

Abstract
This article addresses the control of nonlinear time-delay descriptor systems via Composite Nonlinear Feedback (CNF) control technique to attain both improved transient response and asymptotic output regulation. The suggested CNF controller not only prevails for improving the closed-loop system's transient response, but it is also efficient in overcoming the input saturation constraint and time-delay effects (both constant and time-varying delays). Moreover, the suggested controller is designed under the delay-range dependent condition which causes it to be less conservative than other CNF controllers discussed so far in the literature. The CNF controller's parameters are obtained by solving LMI problems through the given theorems based on the Lyapunov approach to stability analysis. The theoretical achievements are admitted by computer simulation of some illustrative examples.

Abstract
Wound healing is a dynamic process that occurs in the tissue under the skin. During this process, oxidative stress biomarkers are excessively produced, which finally lead to inflammation and cellular damage. In this study, efforts have been made to evaluate the antioxidant effect and wound healing activity topical formulation containing Heliotropium bacciferum Forssk extract. The in vitro antioxidant properties were evaluated using 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activities and the ferric reducing antioxidant power (FRAP) assay. The herbal ointments (2.5% w/w and 5% w/w) were prepared from the hydroalcoholic extract of H. bacciferum Forssk and administrated on the induced wounds in Wistar rats. The chromatic assay, percentage of wound contraction, and histopathological studies were used for evaluating the wound healing activity. For the evaluation of reactive oxygen species (ROS), catalase (CAT) activity, superoxide dismutase (SOD), and glutathione (GSH) levels were examined. The DPPH method showed tremendous radical scavenging activities at the corresponding concentrations with EC50 value of 80μg/mL. Topical application of the ointment (5% w/w) showed the highest wound contraction in comparison to the positive control (treated with CICALFATE™) and the control group (treated with normal saline). Similarly, the histological study of the group treated with the extract ointment (5% w/w) showed full collagen tissue deposition with a complete epidermal regeneration. The results of the assessment of GSH levels as well as CAT and SOD activities in the treated group (5% w/w) confirmed the scavenging property of the extract ointment. Our findings indicated the proper wound healing impact of the topical formulation of H. bacciferum Forssk due to its notable antioxidant capacity.

Abstract
In this paper, an observer-based improved Composite Nonlinear Feedback (CNF) controller is proposed for output tracking of general time-varying reference signals in descriptor systems subject to actuator saturation. Different parts of the proposed control law are designed based on the reconstructed states by a full-order descriptor observer. Algebraic constraints in descriptor systems can significantly complicate design procedures of the observer and the controller. Moreover, considering the actuator saturation constraint, adds additional complexity to the tracking problem. On the other hand, the proposed improved CNF controller's performance is also challenged in presence of external disturbances. The effect of external disturbances, along with the previous mentioned constraints, needs extremely intricate calculations for investigating the solvability of the tracking problem. Furthermore, due to the nonlinearity of the closed-loop system, steady-state analysis is also needed to show the uniformly ultimately boundedness of the tracking error in presence of external disturbances. In this regard, precise mathematical operations are performed through a theorem, which investigates the tracking goal for three different cases of the saturation function. Finally, the theoretical achievements are verified by computer simulations through numerical and practical examples.

Abstract
INTRODUCTION Currently, the pulsed electromagnetic field (PEMF) method is utilized for the treatment of nonunion long bone fractures. Considering the established effect of the PEMF on the acceleration of the bone healing process, we conducted this study to evaluate the effect of PEMF on the healing process in mandibular bone fractures. MATERIAL AND METHODS This research was a randomized control trial (RCT) study. The sample consisted of patients with a mandibular fracture who were hospitalized in order to receive closed reduction treatment. The participants were randomly selected and then sequentially divided into two groups of 16 participants each (controls = 16, cases = 16). The patients in the control group received conventional therapy without any extra treatment, while the patients in the case group received PEMF therapy in addition to conventional therapy. For the PEMF therapy, patients in the case group received immediate post-surgery PEMF therapy for 6 h. Next, they received 3 h of exposure for the next 6 d, and finally, the same process was repeated for 1.5 h for post-surgery days 8-13. The maxillomandibular fixation (MMF) device was removed at post-surgery week 4. The patients in the control group, however, did not receive any extra treatment. The efficiency of the treatment modalities was evaluated clinically and radiographically. For the radiographical assessment, we employed a direct digital panoramic machine to calculate the computerized density of the bone, and those measurements were used for comparison of the results between the control group and the study patients. RESULTS There was no significant difference in the mean bone density values between the two groups (P > 0.05). However, the percentage of changes in bone density of the two groups revealed that the case group had insignificant decreases at post-surgery day 14 and a significant increase at post-surgery day 28 compared with the control group (P < 0.05). After releasing the MMF, a bimanual mobility test of the fractured segments showed the stability of the segments in all patients. In the case group, the mouth opening was significantly more stable than that of the control group (P < 0.05). CONCLUSION PEMF therapy postoperatively leads to increased bone density, faster recovery, increased formation of new bone, a further opening of the mouth, and decreased pain.

Abstract
INTRODUCTION Asthma is a chronic inflammatory disease of the airways. In this study, we evaluated the anti-inflammatory effects of myrtenol on the inflammatory indices in the pulmonary parenchyma and airways and on the inflammatory and oxidative indices of the bronchoalveolar lavage fluid (BALF) of asthmatic rats. METHODS The allergic asthma was induced by sensitization (two weeks) followed by the inhalation of ovalbumin (four weeks). Animals were divided into two main groups: (1) Histopathology, and (2) measurement of inflammatory and oxidative biomarkers in the BALF. Each main group was subdivided into four subgroups: Control, Asthma, Asthma+Dexamethasone and Asthma+Myrtenol. (-)-Myrtenol (50mg/kg) or Dexamethasone (2.5mg/kg) was administered intraperitoneally once a day for one week, at the end of the inhalation period. On day 50, lung histopathologic parameters and inflammatory indices in BALF including INF-γ, IL-10, IL-1β, and TNF-α and oxidative stress biomarkers (MDA, SOD, and GPX) were measured. RESULT In the Asthma group, leukocyte infiltration, the thickness of smooth muscle and epithelium of airways wall and the number of goblet cells increased. Myrtenol reduced all of the above-mentioned indices except the epithelium thickness. It also inhibited the increase in BALF IL-1β, TNF-α and MDA and increased the levels of INF-γ, IL-10 and SOD. CONCLUSION Our results suggest that myrtenol reduced damage caused by experimental asthma by reducing the inflammatory indices, normalizing the level of interleukins and balancing oxidative stress in the lungs. It also prevented airway remodeling. Myrtenol may be suggested as a potent herbal medicine for the treatment of allergic asthma.

Abstract
Fusarium mycotoxins are frequent contaminants of cereals in many world regions, and are suggested risk factors for various acute and chronic human diseases. To date a lack of exposure tools has restricted epidemiological studies of the potential health effects. Recently established exposure biomarkers for deoxynivalenol (DON) and fumonisins are now available and here a pilot biomarker survey of 110 women (aged 39 to 72 years) from Golestan, northern Iran was conducted on samples collected at one time point during August-September 2007. Urinary DON and DON-glucuronide combined were detected frequently (79/110, 72%), mean 1.3 ng DON/ml urine, range not detected (nd)-6.5 ng/ml; mean creatinine adjusted levels were 1.5 ng DON/mg creatinine, range nd-7.1 ng/mg). Neither urinary de-epoxy DON (DOM-1) and DOM-1 glucuronide combined, nor urinary fumonisin B1 were detected. This study is the first reported biomarker based exposure assessment of DON and fumonisins in this region. Overall DON exposure at this time point appears modest compared to other world regions where data are available.

Abstract
Quinazolinone ring system is renown because of its wide spectrum of pharmacological activities due to various substitutions on this ring system. In this study, the minimum inhibitory concentration of the synthesized compounds in our laboratory was determined by micro dilution Alamar Blue(®) Assay against six strains of bacteria (three Gram-positive and three Gram-negative) and three strains of fungi. Following a broth micro dilution minimum inhibitory concentration (MIC) test, Minimum Bactericidal Concentration (MBC) and Minimum Fungicidal Concentration (MFC) tests were performed. Cytotoxic effects of the compounds were measured using the MTT colorimetric assay on HeLa cell line. Results of antimicrobial screening showed that compounds had better bacteriostatic activity against Gram-negative bacteria. Results from MBC revealed that these compounds had more significant bacteriostatic than bactericidal activities. Nearly all screened compounds showed good activity against C. albicans and A. niger. Results from MFC indicated that these compounds had better fungistatic rather than fungicidal activities. The synthesized target molecules were found to exhibit different cytotoxicity in the range of 10 to 100 μM on HeLa cell line. Compounds 6 and 7 exhibited acceptable cytotoxicity approximately 50% at 10 μM concentration.

Abstract
BACKGROUND Intellectual disability (ID) has a worldwide prevalence of 1-3% and results from extraordinary heterogeneous. To shed more light on the causes of ID in Kerman Province, in Southeast Iran, we set out in 2008 to perform systematic clinical studies and homozygosity mapping in large Iranian families with ID. METHODS Fifty seven families with a minimum of two mentally retarded children from Kerman Province were initially tested for metabolic disorders, by Tandem mass spectrometry. Fragile X testing and standard karyotyping were performed for all probands of families. Cases with autosomal recessive (AR) pattern of inheritance and microcephaly were subjected to homozygosity mapping by using several microsatellite markers for known MCPH loci. RESULTS Three out of seven families with X-linked pattern of inheritance were positive for fragile X syndrome. Chromosome abnormality was not observed in any of dysmorphic patients and all families were negative for metabolic tests. Among the remaining 50 families of AR ID, six were found to be microcephalic, of which 2 linked to two MCPH loci (33.3%). The rest 4 families were not linked to any of the known loci. CONCLUSION The results of this study showed that ID with microcephaly comprised 12% of ID cases in Kerman Province. In two families with apparent linkage to the MCPH5 and MCPH6 locus, mutation screening was not successful, which might indicate that either the mutation is located in the regulatory sequences of the gene or that there might be another genes present in these regions, which is mutated in such cases.

Abstract
BACKGROUND There is long-term interest in the effects of stress on health, due to the strain that it places on individuals which can lead to an increased risk of disease. The present study examined degree of perceived job stress related to incidents reporting rate and its dimensions among workers' Isfahan Steel Company. METHODS A self-administered anonymous was distributed to 189 workers. The survey included demographic factors, incidents reporting rate and its components (physical symptoms, psychological symptoms and accidents) and the Job Stress Questionnaire. The data were analyzed by multivariate (MANOVA) and correlation techniques. RESULTS 1) there was internal significant correlation between perceived job stress with incident reporting rate as well as with its two components namely physical symptoms and psychological symptoms; 2) there was not a significant relationship between perceived job stress and accident; 2) In multivariate analysis, perceived job stress respectively about 12%, 18% and 19% of the variance of variables of incidents reporting rate, physical and psychological symptoms significantly predicted (P< 0.05). CONCLUSION Perceived job stress influences to physical and psychological symptoms. Therefore, decreasing job stress can be important to prevent the development of stress-related diseases and to promote workers health.

Abstract
Quinazolinones are interesting molecules with a wide range of biological activities. We prepared a number of quinazolinone derivatives by the condensation of 5-bromo- or 5-nitro-substituted anthranilic acids with chloro-acyl chlorides. Anthranilic acid derivatives were treated with either 3-chloro-propionyl chloride or 4-chloro-butyryl chloride to yield the corresponding N-acyl-anthranilic acids. The resultants were reacted with acetic anhydride to afford the benzoxazinone intermediates, which upon condensation with elected amines in either DMF or ethanol gave the corresponding tricyclic 4(3H)-quinazolinone derivatives. It was found that reactions in DMF produced higher yields.

Abstract
Irritable bowel syndrome (IBS) is the most prevalent functional gastrointestinal disorder noted in the general population worldwide. Its chronic nature, signs and symptoms which vary periodically from mild to severe have many negative effects on the quality of life for the sufferer; therefore the appropriate treatment of these patients is highly important. Patients should be informed by their doctors that the nature of the disease is benign, and educated on how to deal with and control symptoms of the disease. This article sets out a review of recent studies on the prevalence of IBS in Iran and appropriate methods for management of patients affected by IBS.

Abstract
Zeta sedimentation ratio (ZSR) is a simple, rapid and reproducible test which is not influenced by variables like sex and anemia. There is good correlation with Westergren erythrocyte sedimentation ratio (ESR) in normal and hospital population. Limitation of packing force affects the use of the procedure in polycythemia and in patients with ZSR greater than 80%.

Abstract
When platelet rich plasma is exposed to N-ethylmaleimide, a ten fold increase in measurable prostaglandin E synthesis occurs. This effect is almost completely abolished within 2 hours of ingestion of 600 mg of aspirin by human volunteers. Recovery of this platelet function is slow for the first two days, returning sharply to normal over the next six days and plateauing approximately 8 days following initial removal from aspirin. It is suggested from these studies that platelet prostaglandin E production following NEM may be a useful test of platelet function.
