Background and aims: Several pharmacological and biological activities have been attributed to Cuminum cyminum L. (CC), including analgesic, antioxidant, anti-inflammatory, and anti-epileptic effects. In this regard, the present study evaluated the antidepressant-like effects of the CC essential oil (EO) on the forced swim test (FST) and tail suspension test (TST) in male mice. Materials and Methods: The gas chromatography-mass spectrometry (GC-MS) apparatus was used for detecting the chemical compounds of CC EO. In the present study, 72 male NMRI mice were randomly allocated to 12 groups (each containing 6 animals) including control or vehicle (10 mL/kg, i.p.), fluoxetine (20 mg/kg, i.p.), imipramine (30 mg/kg, i.p), and the CC EO (100, 200, and 300 mg/kg, i.p.). Then, several parameters were measured and recorded, including immobility time, swimming time, and climbing time in FST, along with immobility time in TST, respectively. Results: Cuminaldehyde followed by cymene, γ-terpinene, phenylglycol, 2-caren-10-al, 2-β-pinene, acoradiene, and cuminic acid were the major components of the CC EO. Based on the results, all doses of the CC, fluoxetine, and imipramine reduced immobility time in both FST (P<0.001) and TST (P<0.001). On the other hand, all doses of the CC and fluoxetine increased swimming time (P<0.001) although climbing time was only increased by 200 and 300 mg/kg of the EO (P<0.01 and P<0.001, respectively) and imipramine (P<0.001). Conclusion: Based on the findings of the present study, the components of the CC induced antidepressant-like activity similar to that of fluoxetine and imipramine in both tests. However, further studies are required to confirm the role of different active components and the exact mechanism of action.

Background and aims: Postoperative pain has always been considered by surgeons because of its various complications. The aim of this study was to compare the effect of intravenous, subcutaneous and suppository morphine in reducing post-hysterectomy pain. Materials and Methods: In this clinical trial, 90 patients undergoing hysterectomy were randomized into three groups of 30 each using simple randomization, namely, intravenous, subcutaneous, and suppository morphine (10 mg). Before intervention and 4, 8, 12, and 16 hours after intervention, pain intensity was measured using visual analogue scale (VAS). Relative frequency of nausea, vomiting, itching, bradypnea, and apnea in all groups was recorded. Data were analyzed by SPSS version16.0. Results: Mean pain severity at 0 hour postoperatively (P=0.004), 4 hours postoperatively (P=0.009), 8 hours postoperatively (P=0.009), and 12 hours postoperatively (P=0.001) was significantly higher in the suppository morphine group than in the other two groups. There was no significant difference in pain severity at 16 hours postoperatively among the three groups (P=0.446). According to the results of repeated measures ANOVA, changes in pain severity at the five intervals were statistically significant in all three groups (subcutaneous, intravenous, and suppository morphine groups) (P<0.001). There was also a statistically significant difference in pain severity at the studied intervals among the three groups (P<0.001). The frequency of nausea (P=0.05) and vomiting (P=0.84) was higher in the suppository group than in the other two groups, although the difference was not statistically significant (P=0.05). Conclusion: The results of this study indicated better efficacy of subcutaneous and intravenous morphine in reducing post-hysterectomy pain compared with suppository morphine.

Background and aims: Some biological scaffolds are used as appropriate skin substitutes, including decellularized amniotic membrane or dermis although the ovine pericardial tissue has not been characterized or used for skin tissue engineering. In this regard, this study focused on the decellularization and characterization of ovine pericardium for skin tissue engineering. Materials and Methods: To this end, two different methods were used for decellularization, including safety data sheet (SDS) 1% (method 1) and Triton X-100 1% (method 2). In addition, histological examinations (H&E staining), DNA content assay, scanning electron microscopy (SEM), MTT test using human adipose-derived mesenchymal stem cells, and tensile tests were conducted for sample characterization. Results: Based on the results, the DNA content showed significant DNA removing (P<0.001) after decellularization with methods 1 and 2 in comparison to native tissues although the significance level between the two methods was P=0.06. In the SEM examination, cells were effectively removed while the extracellular matrix remained intact in both groups. Based on the results of the MTT test, the toxicity was not significant (P=0.36). On the other hand, mechanical property assay revealed a higher value of Young’s modulus in method 1 (34.12 MPa) compared to Method 2 (32.57 MPa) and native tissues (30 MPa). Finally, the highest strain at the break point (approximately 0.6) belonged to the native sample. Conclusion: In general, the ovine seems to be a good alternative for skin tissue engineering and regeneration since it is a post-slaughtering waste tissue has low thickness, is wide and spread, and easy to be decellularized with SDS 1% and Triton X-100. Eventually, it has good properties for cell seeding based on the findings of our study and the capability of vascularization reported in the literature.

Background and aims: Although some preclinical and clinical studies have extensively confirmed the pharmacological effects of the hydroalcoholic extract (HE) of Physalis alkekengi on several diseases, little is known about the effects of P. alkekengi HE (PAHE) on breast cancer. Therefore, this study aimed to investigate the therapeutic effect of PAHE on estrogen receptor+ breast cancer. Methods: To this end, tumors were created in mice by injecting MC4L2 cells into the sternum of the mice. Then, the animals were gavaged for 16 days at 10, 50, and 100 mg/kg daily of PAHE. In addition, the tumor growth and body weight of the mice were measured on the 16th day, and they were killed on 21st day. Finally, their tumor tissues were removed and the apoptotic cell tissue and expression of the ATG-5 gene were studied as well. The experiments were repeated three times, and the data were analyzed using SPSS software (P<0.001 and P<0.05). Results: The average body weight of the control group significantly decreased 16 days after tumor establishment (P<0.001). Further, the PAHE inhibited the growth of the breast cancer tumor in higher doses (50 & 100 mg/kg, P<0.001). Based on the results, a significant histopathological alteration was found in the breast tumors of the PAHE-treated groups compared with the control group, including the decreased level of mitotic cells the intensive level of necrotic cells and lymphocyte infiltration into the breast tumors bearing mice 21 days after PAHE administration (P=0.012). Eventually, PAHE significantly increased the mRNA level of the expression of the autophagy ATG-5 specific gene in the effective dosage-treated group (50 mg/kg, P=0.037). Conclusion: The evidence suggests that the PAHE has a suitable efficacy for the treatment of ER+ breast cancer by promoting autophagy mechanisms into these tumor types
背景与目的:虽然一些临床前和临床研究已经广泛证实了alkekengi Physalis hydroalcohol提取物(HE)对多种疾病的药理作用，但对P. alkekengi HE (PAHE)对乳腺癌的作用知之甚少。因此，本研究旨在探讨多环芳烃对雌激素受体+乳腺癌的治疗作用。方法:在小鼠胸骨内注射MC4L2细胞，形成肿瘤。然后按每天10、50、100 mg/kg的剂量灌胃16 d。第16天测定小鼠肿瘤生长情况和体重，第21天处死。最后切除肿瘤组织，观察凋亡细胞组织及ATG-5基因表达情况。实验重复3次，数据采用SPSS软件进行分析(P<0.001和P<0.05)。结果:对照组小鼠肿瘤建立后16 d平均体重显著降低(P<0.001)。此外，高剂量的PAHE抑制乳腺癌肿瘤的生长(50和100 mg/kg, P<0.001)。结果显示，与对照组相比，PAHE治疗组乳腺肿瘤发生了明显的组织病理学改变，有丝分裂细胞减少，坏死细胞增多，淋巴细胞浸润至乳腺肿瘤21 d (P=0.012)。最终，PAHE显著提高了有效剂量组小鼠自噬ATG-5特异性基因mRNA表达水平(50 mg/kg, P=0.037)。结论:有证据表明，PAHE通过促进ER+乳腺癌的自噬机制，在治疗ER+乳腺癌中具有合适的疗效

Background and aims: The role of Helicobacter pylori in the development of gastric ulcer and gastrointestinal cancer was identified in this study. More precisely, the study focused on the creation of a DNA vaccine based on the cagT gene of this bacterium and the investigation of its immunogenicity against H. pylori in infused BALB/c mice. Materials and Methods: To this end, the pcDNA3.1(+)-cagT was prepared and transformed into Escherichia coli. Then, animals were injected with recombinant pcDNA3.1(+)-cagT plasmid, pcDNA3.1(+)-cagT + nanoparticles, and pcDNA3.1(+). After the plasmid purification and confirmation of the transformation by digestion and polymerase chain reaction (PCR), chitosan nanoparticles were synthesized using the ionic gelation method. Next, the animals were classified into three groups each including 21 mice. The injectable solutions including pcDNA3.1(+)-cagT, pcDNA3.1(+)-cagT + nanoparticles, or empty pCDNA3.1 (as a control group) were injected into the quadriceps muscle of mice, separately. Finally, the blood and tissue samples of each mouse were collected 15, 30, and 45 days after the last injection, and the expression levels of transforming growth factor-beta (TGF-β1), interleukin-4 (IL-4), and interferon-gamma (IFNγ) were evaluated by real-time PCR. Results: The IFNγ and TGF-β1 expression increased in the infused mice (P<0.01) while the IL4 expression represented a significant decrease (P<0.01). Moreover, the IFNγ and IL4 expression level in pcDNA3.1(+)-cagT + nanoparticle significantly altered (P<0.01) compared to the pcDNA3.1(+)-cagT group although the TGF-β1 expression was not significantly different (P=0.075). Contrarily, the cagT gene expression in the tissue samples of both groups was significantly different 15, 30, and 45 days after the last injection (P<0.01). Eventually, the expression of the cagT gene in the infused mice by pcDNA3.1(+)-cagT and in the nanoparticle group was not significantly different 45 days after the last injection (P=0.105). Conclusion: In general, the decrease of IL-4 expression was observed in the injected mice by pcDNA3.1(+)-cagT and indicated that the immune system work by a Th1 pattern. The findings showed that a pcDNA3.1(+)-cagT construct combined with chitosan nanoparticles can increase the stimulation of the immune system in an animal model and thus it can be used as an appropriate method for controlling H. pylori infection.

Background and aims:miRNAs have regulatory functions in developmental processes. The stages of spermatogenesis can also be affected by miRNAs. We tried to detect a relationship between the expression of miR-508-5p and miR-510-5p and male infertility. The purpose of this study was to investigate the association between expression of miR-508-5p and mir-510-5p in ejaculated sperm from patients with idiopathic asthenozoospermia, teratozoospermia, and teratoasthenozoospermia. Materials and Methods:We enrolled 18 men with asthenozoospermia, 17 men with teratozoospermia, 18 men with teratoasthenozoospermia, and 18 individuals with normozoospermia based on the clinical criteria. Then, the expressions of the mentioned miRs in the spermatozoa were evaluated by quantitative real-time PCR (qRT-PCR). Kruskal-Wallis was used to compare their expressions in the studied groups. Results: The expression of mir-508-5p did not show any statistical significance in all groups. On the other hand, the expression of miR-510- 5p in teratozoospermia groups (P<0.05) and the asthenozoospermia group (P<0.05) demonstrated a significant downregulation compared with the control and teratoasthenozoospermia groups. Conclusion: By analyzing the expression profile of miRNAs, we concluded that the expression level of miR-510-5p changed in patients with abnormal motility and morphology of spermatozoa; therefore, it may affect infertility by down-regulating the expression of mir-510-5p which shows the role of it in abnormal morphology and motility defects in infertility cases.

Background and aims: Constipation is one of the most common issues in pediatrics. The aim of this study was to compare the effect of polyethylene glycol and the simultaneous administration of polyethylene glycol along with probiotics in the treatment of chronic functional constipation. Materials and Methods: In this randomized double-blind clinical trial, 150 children with chronic functional constipation referred to Imam Ali Clinic affiliated with Shahrekord University of Medical Sciences from 2017 to 2018 were included. The first group (A) consumed 1 g/ kg of body weight per day of water-soluble polyethylene glycol powder and the second group (B) consumed a probiotic powder and 1 g/kg of body weight of the water-soluble polyethylene glycol powder daily. In weeks 0, 1, and 2, questionnaires were filled out by the parents of the children and the data were analyzed. Results: The results showed that there was no significant difference in any of the variables between groups A and B (P=0.07) including the frequency of fecal excretion in week 1 (77% and 71%) and week 2 (4% and 5.4%) and stool consistency in week 1 (4% and 6.7%) and week 2 (86.7% and 92%). Moreover, there was no significant difference between groups A and B in any of the variables frequency of painful excretion in week 1 (74% and 73%, respectively) and week 2 (5.3% and 4%, respectively), frequency of abdominal pain in week 1 (61.3% and 49.3%, respectively) and week 2 (4% and 5.3%, respectively), and the frequency of fecal incontinence in week 1 (22.77% and 18.7%, respectively) and week 2 (6.7% and 1.3%) (P>0.05, respectively). Conclusion: Our results indicated that the administration of probiotic supplement (Lactobacillus Rhamnosus, Lactobacillus acidophilus, Lactobacillous Bulgaricus) has no effect on the improvement of symptoms in children with chronic constipation.

Background and aims: Antimicrobial peptides constitute a family of bioactive peptides that are involved in the body defense. Recently, their anti-cancer properties, especially by inducing apoptosis, have been proven in in vitro studies. Therefore, in this study, the effects of cecropin B as an antimicrobial peptide on breast cancer growth, hematological parameters, and histopathological changes in rats were evaluated. Methods: Twenty-four female rats were randomly divided into 4 groups. The cancer group, control group, cecropin B group, and cancer group treated with cecropin B. The tumor size was measured at the beginning and the completion of the treatment period. Blood samples were collected for assessment of the hematological parameters and Bax and Bcl2 levels. Tumor tissues were removed for histopathological analysis. Results: The tumor size had a significant increase in the cancer group and cancer group treated with cecropin at the end of the treatment. A significant decrease in mean cell volume, white blood cell count and Bcl2 level and a significant increase in hemoglobin and Bax levels were observed in the cancer group treated with cecropin B compared to cancer group. Changes in other parameters were not significant. Histopathological study showed the invasion of mitotic cells to stromal and muscular tissues of the breast in the cancer group, while focal destruction of tissue and cell death were observed in the cancer group treated with cecropin B. Conclusion: The results showed that cecropin B has been able to reduce tumor growth and have little side effects on hematologic factors probably through apoptosis.

Background and Objectives: Finding the best diet is very important to rear Lucilia sericata larvae for therapeutic purposes and prepare standard curves in forensic entomology. The aim of this study was to find the best diet for larvae in maggot therapy. Furthermore, this study was conducted to obtain a vertical life table and measure the length and width of immature stages of L. sericata for forensic entomology. Materials and Methods: Larvae of L. sericata (Karaj strain) were used to evaluate diets. The tests were carried out in three replicates of 100 eggs for each diet including chicken liver, blood agar, and fish food at the same time. Independent t-test, ANOVA, and Tukey’s post-hoc tests were used to compare the mean length and width of larvae between different groups. A P-value of less than 0.05 was considered significance level. Results: In contrast to the first and the second larval instars, there was a significant difference in the mean length and width of the third instar larvae (P<0.001). At the third instar larval stage, those larvae that had been fed on chicken liver were significantly larger than the others. There were also no significant differences between life expectancy, overall survivorship rate, and force of mortality of larval groups fed on three different diets. Conclusions: Chicken liver is an advisable diet for nurturing larvae and plotting standard curves in forensic entomology. For rearing the first and the second larval instars in sterile conditions, blood agar and fish food can serve as suitable diets.

Background and aims: Synthetic dyes are widely used as food additives to avoid the loss of original dye in processed foods and to make the foods more attractive to consumers. For simultaneous determination of 8 most commonly used synthetic colors in beverage and foodstuff, an efficient, selective, and sensitive method is suggested. Methods: To analyze food colors in different beverages and fruit roll-ups, a method using Ion-pair high-performance liquid chromatography with diode array detector was suggested and validated. The separation of dyes from beverage and foodstuff was done by solid-phase extraction (SPE). The ultrasound-assisted solvent extraction method was used to extract dye from fruit roll-ups. Results: The limit of detection and the limit of quantification ranged from 0.036 to 0.07 and 0.098 to 0.2 µg/mL, respectively. IP-HPLC-DAD method was validated using precision (RSD %) and accuracy (Recovery %) of two concentrations of 0.5 and 1 µg/mL in terms of intra- and inter-day. SPE method was also validated using intra- and inter-day precision and accuracy. The most commonly detected dye in the tested samples was carmoisine with a concentration of 386 µg/g. Additionally, the concentration of dye was higher than the permitted level in 28.6% of beverages, 40% of edible ice products, and 100% of fruit roll-ups (Lavashak). Conclusion: This method is an effective, appropriate, accessible, reliable and safe analytic method to analyze eight food dyes
