Abstract
Controlling the wound exudates accompanied by microbial wound infections has still remained as one the most challenging clinical issues. Herein, a chitosan/gelatin/polyvinyl alcohol xerogel film containing Thymus pubescens essential oil is fabricated for antimicrobial wound dressing application. The chemical and physical characteristics of the devised formulation is characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, atomic force microscope, and tensile tests. Moreover, swelling capability, water vapour transmission rate, water contact angle, solubility, moisture content, and release properties are also studied. The antimicrobial and antibiofilm tests are performed using the broth microdilution and XTT assay, respectively. The produced formulation shows excellent antimicrobial efficacy against Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Candida species. It is also demonstrated that the obtained film can reduce (∼80 %) Candida albicans biofilm formation, and its biocompatibility is confirmed with MTT (∼100 %) and hemolysis tests. The antimicrobial activity can be correlated to the microbial membrane attraction for Candida albicans cells, illustrated by flow cytometry. This proposed film with appropriate mechanical strength, high swelling capacity in different pH values (∼200-700 %), controlled release property, and antimicrobial and antioxidant activities as well as biocompatibility can be used as a promising candidate for antimicrobial wound dressing applications.

Abstract
Zataria multiflora essential oil is a natural volatile plant product whose therapeutic applications require a delivery platform. Biomaterial-based hydrogels have been extensively used in biomedical applications, and they are promising platforms to encapsulate essential oils. Among different hydrogels, intelligent hydrogels have recently attracted many interests because of their response to environmental stimuli such as temperature. Herein, Zataria multiflora essential oil is encapsulated in a polyvinyl alcohol/chitosan/gelatin hydrogel as a positive thermo-responsive and antifungal platform. According to the optical microscopic image, the encapsulated spherical essential oil droplets reveal a mean size of 1.10 ± 0.64 μm, which are in consistent with the SEM imaging results. Encapsulation efficacy and loading capacity are 98.66 % and 12.98 %, respectively. These results confirm the successful efficient encapsulation of the Zataria multiflora essential oil within the hydrogel. The chemical compositions of the Zataria multiflora essential oil and the fabricated hydrogel are analyzed by gas chromatography-mass spectroscopy (GC-MS) and Fourier transform infrared (FTIR) techniques. It is found that thymol (44.30 %) and γ-terpinene (22.62 %) are the main constituents of the Zataria multiflora essential oil. The produced hydrogel inhibits the metabolic activity of Candida albicans biofilms (~60-80 %), which can be related to the antifungal activity of the essential oil constituents and chitosan. Based on the rheological results, the produced thermo-responsive hydrogel shows a gel-sol viscoelastic transition at a temperature of 24.5 °C. This transition leads to a facile release of the loaded essential oil. The release test depicts that about 30 % of Zataria multiflora essential oil is released during the first 16 min. In addition, 2, 5-diphenyl-2H-tetrazolium bromide (MTT) assay demonstrates that the designed thermo-sensitive formulation is biocompatible with high cell viability (over 96 %). The fabricated hydrogel can be deemed as a potential intelligent drug delivery platform for controlling cutaneous candidiasis due to antifungal effectiveness and less toxicity, which can be a promising alternative to traditional drug delivery systems.

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:
In the current research, a green, fast and cheap extraction method based on deep eutectic solvent was developed for the preconcentration of phenylalanine. Then, high performance liquid chromatography (HPLC) as a sensitive and accurate technique was used to determine amounts of preconcentrated phenylalanine.
Objective:
The combination of the HPLC technique and extraction procedure using deep eutectic solvent makes it possible to find a good procedure for the preconcentration of phenylalanine in different media with acceptable precision and accuracy.
Methods:
Decanoic acid and tetrabuthylammonium bromide were used as the components of the green solvent. Then, the synthesized green solvent was used for the preconcentration of phenylalanine. HPLC equipped with a UV-VIS detector, a C18 column, a mixture of sodium dihydrogen phosphate 2-hydrate (20 mM, pH 6.60)-ACN (70-30 %) as the mobile phase, and the wavelength of 245 nm were selected as the best separation.
Results:
The chief characteristic of deep eutectic solvent was identified using Fourier transform infrared spectroscopy. Central composite design to evaluate the effects of preconcentration parameters showed that the pH value of 6.31, salt concentration of 0.272 M, DES volume of 226 μL, and stirrer time of 5.60 min were suggested as the best conditions of separation. Total analysis time was 5.50 min.
Conclusion:
Validation of designed analysis exposed good linearity (0.015-1.50 µg/mL), suitable sensitivity, excellent preconcentration (32.50) and enrichment (21.15) factors, acceptable relative standard deviation (3.07 %), and low amounts of detection limit (0.015 µg/mL). Finally, the designed method was effectively used for the determination of phenylalanine in cheese and yoghurt with relative recoveries of 113.33 to 125.00 % and 94.00 to 100.00 %, respectively.

Abstract
BACKGROUND Intracanal disinfection is a critical, yet challenging goal for long-term success in regenerative-based treatments. This in-vitro study aimed to assess the release profile of triple antibiotic- eluting Injectable Platelet-Rich Fibrin (I-PRF) constructs in 28 days. METHODS I-PRF scaffolds containing triple antibiotic mixture [Metronidazole (MET), Ciprofloxacin (CIP), and Minocycline (MINO)] by immersion (group one), I-PRF scaffolds containing triple antibiotic mixture by integration (group two), and antibiotic-free I-PRF scaffolds (group three) were fabricated. The antibiotic release from the scaffolds was measured using High-Performance Liquid Chromatography (HPLC) (the mobile phase of 0.1% formic acid and methanol (35:65 v/v), a C18 analytical column (150 × 4.6 mm, 5 μm) at a flow rate of 0.7 mL/min, at 25ºC) at days 1, 3, 7, 14, 21, and 28. RESULTS Retention times for MINO, CIP, and MET were achieved as 2.3, 2.6, and 3.1 min, respectively. The maximum UV absorbance values for CIP, MET, and MINO were 268 nm, 278 nm, and 350 nm, respectively. The results of the first group showed burst release within the first 24 hours followed by sustained maintenance of all three antibiotics up to 14 days. MINO and MET were still detectable in the third week. The second group could not sustainably release the antibiotics. CONCLUSION The developed method for the simultaneous identification and quantification of each antibiotic in I-PRF was sensitive and quick. Overall, group one could take up the antibiotics in adequate quantities and then subsequently release them over the study period.

Abstract
Background Toxoplasmosis is a zoonotic disease caused by the obligate intracellular parasite, Toxoplasma gondii. This global infectious disease has been associated with behavioral changes in rodents and can result in humans' neuropsychiatric symptoms. Since the neurotransmitters alteration can cause a behavioral change, in this study, tyrosine level, as a precursor of dopamine, was evaluated in acute murine toxoplasmosis during 2015 and 2016 in Shiraz, Iran. Methods At the first, 105 tachyzoites of T. gondii were subcutaneously inoculated to 50 BALB/c mice as experimental groups and 10 mice inoculated by PBS considered as the control group. After that, daily, one group of mice was bled, and sera were collected. Then, their serum tyrosine level was evaluated by HPLC method. Results After data analysis, the maximum mean serum tyrosine level was seen at 2th day of post parasite inoculation (0.0194 mg/ ml), with a significant difference compared to the control group (0.0117 mg/ ml, P=0.025). Moreover, the least quantity of serum tyrosine (0.076 mg/ml) was seen on the 5th day, after parasite inoculation, however, no significant difference was seen. Conclusion Serum tyrosine level increased in 2 d after inoculation of Toxoplasma, but the level regularly decreased in successive days. Tyrosine level increased by phenylalanine hydroxylase 2 days after inoculation, then tyrosine decreased by tyrosine hydroxylase in the next days. Toxoplasma tyrosine hydroxylase enzymes, at primary days of toxoplasmosis, effect on tyrosine production, and after that, the most effect on tyrosine consumption.

Abstract
Methotrexate (MTX) is a folate antagonist drug used for several diseases, such as cancers, various malignancies, rheumatoid arthritis (RA) and inflammatory bowel disease. Due to its structural features, including the presence of two carboxylic acid groups and its low native fluorescence, there are some challenges to develop analytical methods for its determination. MTX is metabolized to 7-hydroxymethotrexate (7-OH-MTX), 2,4-diamino-N10-methylpteroic acid (DAMPA), and the active MTX polyglutamates (MTXPGs) in the liver, intestine, and red blood cells (RBCs), respectively. Additionally, the drug has a narrow therapeutic range; hence, its therapeutic drug monitoring (TDM) is necessary to regulate the pharmacokinetics of the drug and to decrease the risk of toxicity. Due to environmental toxicity of MTX; its sensitive, fast and low cost determination in workplace environments is of great interest. A large number of methodologies including high performance liquid chromatography equipped with UV-visible, fluorescence, or electrochemical detection, liquid chromatography-mass spectroscopy, capillary electrophoresis, UV-visible spectrophotometry, and electrochemical methods have been developed for the quantitation of MTX and its metabolites in pharmaceutical, biological, and environmental samples. This paper will attempt to review several published methodologies and the instrumental conditions, which have been applied to measure MTX and its metabolites within the last decade.

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
Resistance of many pathogens to available drugs is a global challenge and is leading to growing interest in natural alternative products. In this study, chemical composition and in vitro antibacterial and antifungal activities of the essential oil from Salvia mirzayanii were investigated. The chemical constituents of essential oil from S mirzayanii were analyzed by gas chromatography–mass spectrometry. The antimicrobial activity was determined by broth microdilution. The main identified compounds were 1,8-cineole (41.2 ± 1.3%), linalool acetate (11.0 ± 0.5%), and α-terpinyl acetate (6.0 ± 0.4%) (mL of essential oil/g of plant material). The MIC95 were 0.03 to 0.5 µL/mL and 16 to 128 µL/mL for gram-positive and gram-negative bacteria, respectively. These results indicated that Salvia mirzayanii essential oil significantly inhibited the growth of standard and clinically isolated tested yeasts by MIC50 0.03 to 1 µL/mL. Potent antibacterial and antifungal activities of Salvia mirzayanii essential oil may be considered in future study, particularly against antibiotic-resistant cases.

Abstract
BACKGROUND Walnut hydrosol (WH) is used extensively by Iranian people with diabetes in order to control blood sugar (BS). There are few data regarding the effect of walnut on controlling diabetes. OBJECTIVES A pilot study to determine the efficacy and safety of WH in patients with type 1 diabetes. MATERIALS AND METHODS Eight patients with diabetes mellitus (DM) type 1 were enrolled in the study. They did not use any medicine except insulin. They were advised to drink 250 mL WH after meals twice a day for four weeks. Their BS level was measured and their insulin dose was changed according to their BS. After four weeks, they discontinued WH use and their BS level was checked for two weeks. Descriptive statistics was used to analyze the data. Also, the essential oil of the sample was extracted using a liquid extractor and then analysis of the constituents was performed. RESULTS The average daily BS level and insulin dose decreased in seven subjects. Two subjects developed generalized pruritic erythematous skin rash. One patient presented hypoglycemic coma. She had no other coma risk factor. Seven compounds were identified in the walnut essential oil and the rate of monoterpenoid and sesquiterpenes hydrocarbons were 53.45% and 5.95%, respectively. The main constituents of the oil were carvacrol (33.21%), thymol (16%) and homoveratrole (15.83%). CONCLUSIONS WH may control the glycemic level in people with diabetes, but it may be associated with minor and major side effects. Further in vitro studies, using these seven compounds, are recommended to determine the efficacy and complications of WH in people with diabetes.

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
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.
