Abstract
Background Liver transplantation and surgical resection are two major strategies for treatment of hepatocellular carcinoma (HCC) patients. One approach to treating HCC is the suppression of metastasis to other tissues. Herein, we aimed to study the effect of miR-4270 inhibitor on migration of HepG2 cells as well as activity of matrix metalloproteinase (MMP) these cells in order to find a strategy to suppress metastasis in future. Methods HepG2 cells were treated with 0, 10, 20, 30, 40, 50, 60, 70, 80, and 90 nM of miR-4270 inhibitor, and then the cell viability was measured by trypan blue staining. Afterwards, cell migration and MMP activity of HepG2 cells were assessed by wound healing assay and zymography, respectively. The MMP gene expression was determined by real-time reverse transcription polymerase chain reaction. Results Results showed that miR-4270 inhibitor decreased the cell viability of HepG2 cells in a concentration-dependent manner. Also, inhibition of the miR-4270 reduced invasion, MMP activity, and expression of MMP genes in HepG2 cells, respectively. Conclusion Our findings suggest that miR-4270 inhibitor decreases in vitro migration, which could help find a new approach for HCC therapy patients.

Abstract
BACKGROUND The expression of genes involved in basic pathways, such as folliculogenesis and steroidogenesis may be affected following prenatal androgen exposure. Besides, exposure to androgens during prenatal life plays a central role in developing polycystic ovary syndrome (PCOS) in females in later life. In the present study, we aimed to examine the expression of the follicle stimulating hormone receptor (FSHR) and activin receptor (actR) genes in ovarian granulosa cells (GCs) of a prenatally-androgenized rat model of PCOS in adulthood. METHODS AND RESULTS In the adult rat model of PCOS and their controls (n = 8 in each group), different phases of the estrous cycle were determined by vaginal smear. Total RNA was extracted from the ovarian GCs using the TRIzol protocol, a reverse transcription kit was used for complementary DNA (cDNA) synthesis, and the expression of FSHR and actR genes was measured by SYBR-Green Real-Time PCR. GraphPad Prism was used for statistical analysis of data, and the t-Student's test was used to compare the results between the two groups. PCOS rats had longer and irregular estrous cycles compared to controls. The expression of FSHR and actR genes were significantly decreased in the rat model of PCOS compared to control rats. In PCOS rats, genes expression ratios for FSHR and actR were 0.91 ± 0.11 times (P = 0.008) and 0.42 ± 0.13 times (P = 0.048) less than controls, respectively. CONCLUSION Reduced expression of the FSHR and actR genes in ovarian GCs may be one of the mechanisms mediating PCOS-related disorders, especially abnormal ovarian folliculogenesis and ovulation dysfunction, following exposure to androgens during fetal life.

Abstract
This study aimed to address the hypothesis that the expression of PTEN and KLLN tumor suppressor genes could diminish in papillary thyroid cancer (PTC) compared to paired normal tissue (PNT) and multinodular goiter (MNG). PTEN and KLLN expressions were assessed at both mRNA and protein levels in 82 tissue samples, including 30 PTC, 30 PNT, and 26 MNG using SYBR-Green Real-Time PCR and enzyme-linked immunosorbent assay (ELISA), respectively. Bioinformatics studies were performed to evaluate the genomic location and the genes promoter region. The mRNA expression of PTEN and KLLN in PTC was significantly lower than PNT (PTEN, P = 0.0033; KLLN, P = 0.0005). A significant decrease in the mRNA level of KLLN was also observed in PTC than MNG (P = 0.0304). Decreased level of PTEN mRNA (odds ratio=0.391; P = 0.013) or KLLN mRNA (odds ratio=0.023; P = 0.025) was associated with an increased risk of PTC tumorigenesis. Areas under the ROC curve for PTEN and KLLN were 0.69 and 0.78, respectively. PTEN and KLLN protein expressions in PTC compared to PNT or MNG were not significantly different. The bioinformatics studies revealed the sequence near the promoter region is lowly conserved across species. Four GC boxes were found upstream of the PTEN transcription start site (TSS), and one TATA box and one GC box were found upstream of KLLN TSS. The results suggest PTEN and KLLN are the two tumor suppressor genes that decreasing or loss of both of them occurs in sporadic PTC tumorigenesis. It appears they could have a promising application in both diagnostic and therapeutic areas.

Abstract
Follicular thyroid carcinoma (FTC) is responsible for approximately 10% of thyroid malignancies. Since this type of malignancy indicates no capsular and vascular invasions, adenoma and follicular carcinoma of thyroid are not distinguishable. It has been proved that microRNAs, which regulate approximately 30% of coding proteins, have an association with follicular thyroid adenoma (FTA) and carcinoma of the thyroid. Therefore, the aim of this study was to assess the expression of some miRNAs for detecting the most appropriate miRNA as potential biomarker in the diagnosis of FTA and FTC patients. Reverse transcription quantitative polymerase chain reaction (RT-qPCR) was applied to determine the expression levels of miR-129-1, miR-146b,-183 and miR-197 in 48 cases (16 FTC, 16 FTA and 16 hyperplasia/multinodular goiter (MNG) cases). The significance of miRNA differential expression levels among groups were assessed using Multivariate test by Statistical Package for Science Software (SPSS v.20) and Graph Pad Prism v.8. Results indicated that all of the miRNAs had significant overexpression in FTC and FTA versus MNG cases, and also increased expression level in FTC in comparison with FTA, however it was not significant. The results of ROC curve analysis determined the significant overexpression and prognostic value of miR-129-1 in FTA cases and miR-146b in both FTA and FTC cases compared to MNG group. Although all of the earlier mentioned microRNAs were overexpressed in FTC and FTA cases, the ROC curve results demonstrated that miR-129-1 had agreeable AUC for FTA cases. Therefore, it seems that it's cut-off point could be helpful in distinguishing between FTA and multinodular goiter cases. On the other hand, although miR-146b has excellent diagnostic value in both FTA and FTC groups, it seems that this microRNA is unable to act as a specific biomarker to discriminate between FTA and FTC cases. This data need to be confirmed in a large cohort study and other biological samples such as plasma.

Abstract
AIMS Hyperoxia has beneficial metabolic effects in type 2 diabetes. However, hyperoxia exacerbates already existing oxidative stress in type 2 diabetes. Nitrate, a nitric oxide donor, is an effective new treatment in type 2 diabetes and also has antioxidant properties. The aim of this study was to determine whether nitrate administration can attenuate hyperoxia-induced oxidative stress in obese type 2 diabetic rats. MAIN METHODS Fifty-six male Wistar rats (190-210 g) were divided into 8 groups: Controls (non-treated, nitrate-treated, O2-treated, and nitrate + O2-treated) and diabetes (non-treated, nitrate-treated, O2-treated, and nitrate + O2-treated). Diabetes was induced using high-fat diet and low-dose of streptozotocin (30 mg/kg). Rats in intervention groups, were exposed to 95% oxygen and consumed sodium nitrate (100 mg/L) in drinking water. Serum fasting glucose, oxidized (GSSG) and reduced (GSH) glutathiones, total oxidant status (TOS), catalase and superoxide dismutase (SOD) activities, and total antioxidant capacity (TAC) were measured after intervention. Oxidative stress index (OSI) was calculated as TOS/TAC ratio. KEY FINDINGS Diabetic rats had increased oxidative stress and hyperoxia exacerbated it. In O2-diabetic rats, nitrate decreased GSSG (102.7 ± 2.1 vs. 236.0 ± 20.1 μM, P < 0.001), TOS (67.7 ± 7.3 vs. 104 ± 3.8 μM, P < 0.001), and OSI (0.44 ± 0.04 vs. 0.91 ± 0.07, P < 0.001) and increased catalase (2.8 ± 0.13 vs. 1.8 ± 0.21 KU/L, P = 0.014), SOD (53.4 ± 1.5 vs. 38.4 ± 1.2 U/mL, P < 0.001), GSH (43.7 ± 1.4 vs. 17.8 ± 0.5 mM, P = 0.003), TAC (152.5 ± 1.9 vs. 116.7 ± 5.0 mM, P < 0.001), and GSH/GSSG ratio (0.43 ± 0.01 vs. 0.08 ± 0.01, P = 0.005). Nitrate also potentiated effects of hyperoxia on decreasing fasting glucose. SIGNIFICANCE Our results showed that dietary nitrate attenuates hyperoxia-induced oxidative stress in type 2 diabetic rats.

Abstract
Thyroid hormones have a role in the regulation of hydrogen sulfide (H2 S) biosynthesis. In this study, we determined the effects of hyperthyroidism on H2 S levels in various tissues and messenger RNA (mRNA) expression of cystathionine-β-synthase (CBS), cystathionine-γ-lyase (CSE), and 3-mercaptopyruvate sulfurtransferase (3-MST) in the liver and muscles of the rat. Sixteen male Wistar rats were divided into the hyperthyroid and the control groups. Hyperthyroidism was induced by adding l-thyroxine (12 mg/L) to drinking water for a period of 21 days. H2 S concentrations in serum, liver, aorta, heart, and soleus muscles, as well as mRNA expressions of CBS, CSE, and 3-MST in these tissues were measured at Day 21. Hyperthyroid rats had lower H2 S levels in the serum compared with controls (14.7 ± 1.4 vs. 25.7 ± 1.6 µmol/L, p < 0.001). Compared with controls, hyperthyroid rats had lower levels of H2 S in the aorta (89%), heart (80%), and soleus (103%) muscles, but higher levels in the liver (35%). Hyperthyroidism decreased the ratio of CBS/CSE mRNA expression in the liver and the CSE/CBS mRNA expression in the muscles by decreasing CBS levels in liver (34% cf. controls) and CSE levels in the aorta, heart, and soleus muscles (respectively, 51%, 7%, and 52% cf.). In addition, hyperthyroidism decreased the mRNA expression of 3-MST in the liver (51%) and aorta (33%), and increased it in the heart (300%) and soleus muscle (182%). In conclusion, hyperthyroidism increased H2 S levels in the liver and decreased it in muscles; these effects are at least in part due to increases and decreases in expression of CSE in the liver and muscles, respectively. These data indicate an association between thyroid hormone status and gene expression of the H2 S-producing enzymes in the rat.

Abstract
XtalFluor-E® has been extensively used in a broad range of reactions in the past few years. Here we report its use with protic nucleophiles in a catalytic manner for the in situ generation of protons that lead to the proto-functionalization of activated olefins. Utilizing the latter protocol, proto etherification of enamides gives rise to N,O-acetals in nearly quantitative yields.

Abstract
Background/Aims: Transient congenital hypothyroidism (TCH) could disturb carbohydrate metabolism in adulthood. Aging is associated with increased risk of type 2 diabetes. This study aims to address effects of TCH on mRNA expressions of glucose transporters (GLUTs) and glucokinase (GcK) in islets and insulin target tissues of aged offspring rats. Methods: The TCH group received water containing 0.025% 6-propyl-2-thiouracil during gestation. Offspring from control and TCH groups (n=6 in each group) were followed until month 19. Gene expressions of GLUTs and GcK were measured at months 3 and 19. Results: Compared to controls, aged TCH rats had higher GLUT4 expression in heart (4.88 fold) and soleus (6.91 fold), while expression was lower in epididymal fat (12%). In TCH rats, GLUT2 and GcK expressions in islets were lower in young (12% and 10%, respectively) and higher in aged (10.85 and 8.42 fold, respectively) rats. In addition, liver GLUT2 and GcK expressions were higher in young (13.11 and 21.15 fold, respectively) and lower in aged rats (44% and 5%, respectively). Conclusion: Thyroid hormone deficiency during fetal period impaired glucose sensing apparatus and changed glucose transporter expression in insulin-sensitive tissues of aged offspring rats. These changes may contribute to impaired carbohydrate metabolism.

Abstract
AIM To compare the effectiveness of 5% benzocaine gel and placebo gel on reducing pain caused by fixed orthodontic appliance activation. SETTING AND SAMPLE POPULATION Thirty subjects (15-25 years) undergoing fixed orthodontics. METHODS AND MATERIALS A randomized, double-blind, placebo-controlled and cross-over clinical trial study was conducted. Subjects were asked to apply a placebo gel and 5% benzocaine gel, exchangeable in two consecutive appointments, twice a day for 3 days and mark their level of pain on a VAS scale. The pain severity was evaluated by means of Mann-Whitney U-test for comparing two gel groups, Kruskal-Wallis nonparametric test for overall differences and post hoc test of Dunnett for paired multiple comparisons. p-value was assigned <0.05. RESULTS The overall mean value of pain intensity for benzocaine and placebo gels was 0.89 and 1.15, respectively. The Mann-Whitney U-test indicated that there was no significant difference between overall pain in both groups (mean difference = 0.258 p ˂ 0.21). For both groups, pain intensity was significantly lower at 2, 6 and 24 h compared with pain experienced at days 2, 3 and 7. CONCLUSION Benzocaine gel caused a decrease in pain perception at 2 h compared with placebo gel. Peak pain intensity was at 2 h for placebo gel and at 6 h for benzocaine gel, followed by a decline in pain perception from that point to day 7 for both gels.

Abstract
PURPOSE Sentinel lymph node biopsy is a fairly new approach for staging of gynecological malignancies. In the current study, the authors comprehensively reviewed the available reports on sentinel node biopsy of endometrial cancer. MATERIALS AND METHODS The authors searched Medline, SCOPUS, ISI web of knowledge, Science Direct, Springer, OVID SP, and Google Scholar with the following search terms: "endometrium OR endometrial OR uterine OR uterus AND sentinel". The outcomes of interest were detection rate and sensitivity. RESULTS Overall, 35 studies had enough information for false negative rate evaluation and 51 studies (including the sub-groups of individual studies) for detection rate evaluation (2,071 patients overall). Pooled detection rate was 77.8% (95% CI: 73.5-81.5%) and pooled sensitivity was 89% (95% CI: 83-93%). Cervical injection, as well as using both blue dye and radiotracer, results in higher detection rate and sensitivity. New techniques such as fluorescent dye injection and robotic-assisted surgery showed high detection rate and sensitivity. CONCLUSION Sentinel node mapping is feasible in endometrial cancer. Using both blue dye and radiotracer and cervical injection of the mapping material can optimize the sensitivity and detection rate of this technique. Larger studies are still needed to evaluate the false negative rate and the factors influencing the sensitivity before considering this method safe.

Abstract
The objective of this experiment was to study the changes of plasma leptin concentration during puberty and its relationship with testosterone level and testis dimensions in Holstein bull calves. Six Iranian Holstein bull calves with approximately 6 months of age were used. Semen evaluation was conducted at 1-month interval to determine the puberty state. To detect the plasma leptin and testosterone changes, blood samples were collected from the jugular vein during pre-puberty (6-7 months of age), puberty (8-9 months of age) and post-puberty (10-11 months of age). In addition, body weight (BW), body condition score (BCS) and testicular width and length were measured at 3-week intervals. The effects of time (age) on total sperm number and percentage of progressive motility of sperm, plasma concentration of leptin and testosterone, amplitude and frequencies of testosterone, BW, BCS, testicular dimensions were significant. Sperm number and progressive motility during post-puberty were higher than those during puberty and pre-puberty. Plasma concentration of leptin during the pre-puberty was higher than those during puberty and post-puberty (p < 0.01). Mean plasma testosterone concentrations during puberty were higher than those during pre-puberty (p < 0.05). BW, BCS and testicular dimensions consistently increased throughout the trial. Results indicated that in growing bull calves, plasma concentrations of leptin decreased during puberty, while circulating testosterone increased.

Abstract
SummaryAim: Sentinel node (SN) biopsy is becoming a standard procedure in the management of several malignancies. Several groups have evaluated the feasibility and value of this procedure in prostate cancer patients. In the current meta-analysis, we comprehensively and quantitatively summarized the results of these studies. Methods: Several databases including Medline, SCOPUS, Google Scholar, Ovid, Springer, and Science direct were systematically searched for the relevant studies regarding SL biopsy in the prostate cancer (“prostate” AND “sentinel” as search keywords). The outcomes of interest were sensitivity and detection rate of the procedure. Results: For detection rate and sensitivity 21 and 16 studies met the criteria of inclusion respectively. Pooled detection rate was 93.8% (95% CI 89–96.6%). Cochrane Q value was 216.077 (I2 = 89.81% and p < 0.001). Pooled sensitivity was 94% (95% CI 91–96%). Cochrane Q value was 14.12 (I2 = 0.0 and p = 0.516). Conclusion: SL biopsy can prevent unnecessary pelvic lymph node dissection in prostate cancer patients. This procedure is feasible with low false negative rate and high detection rate.

Abstract
The aim of the current study was to investigate the effect of feeding a DHA-enriched nutriceutical on the in vitro quality and sperm motility parameters of fresh and frozen-thawed bull semen assessed by CASA. Samples were obtained from nineteen Holstein bulls used for semen collection at Semen Production Center, Karaj, Iran. Control group (n = 10) were fed a standard concentrate feed while treatment group bulls (n = 9) had this standard feed top dressed with 100 g of a commercially available DHA-enriched nutriceutical. Semen quality was assessed on ejaculates collected at the baseline and after 5, 9, and 12 weeks of supplementation. Classical semen evaluation, assessment of sperm motility (subjective and computer-assisted), viability (eosin-nigrosin), and hypo-osmotic swelling test (HOST) were conducted. Semen volume, sperm concentration, and consequently total sperm output were not affected by dietary treatment (P > 0.05). Feeding the nutriceutical was indeed found to affect sperm motility parameters assessed by CASA after 9 weeks of trial. The treatment has improved total motility (P < 0.01), progressive motility (P < 0.05), average path velocity (P < 0.05), HOST-positive (P < 0.01), and proportion of rapid spermatozoa (P < 0.01) in the fresh semen of bulls. Moreover, the proportion of viable spermatozoa increased (P < 0.05) in the ejaculates collected from nutriceutical-fed bulls compared to the control after 12 weeks of feeding trial. The post-thawed HOST and sperm motility data obtained by CASA did not differ between two groups (P > 0.05). On the other hand, dietary supplementation did not affect body weight, BCS and scrotal circumference. Consequently, it can be concluded that dietary DHA supplementation or its precursors, improve in vitro quality and motility parameters of fresh semen assessed by CASA in Holstein bulls. However, this effect was not pronounced in frozen-thawed semen.

Abstract
OBJECTIVE To compare the pregnancy outcome in patients undergoing in vitro fertilization-embryo transfer (IVF-ET) cycles, using human derived follicle-stimulating hormone (FSH) or recombinant FSH for ovarian stimulation protocols. DESIGN Prospective, multi-centre, randomized controlled trial. PATIENTS 115 infertile patients undergoing a first attempt of in vitro fertilization and embryo transfer were included in the study. The inclusion criteria were: female age < 37 years and use of GnRH agonist (GnRH-a) for pituitary downregulation. INTERVENTIONS Long Protocol-controlled ovarian stimulation with human derived FSH or recombinant FSH for IVF-ET. MAIN OUTCOME MEASURES Primary endpoints were implantation rate, clinical pregnancy rate and spontaneous abortion rate. Secondary end-points were total units of FSH injected, days of stimulation, peak estradiol levels at point of hCG administration, mean number of oocytes at pick-up, fertilization rate and cleavage rate. RESULTS No statistically significantly differences in pregnancy outcomes were found in the patients receiving hFSH in comparison to patients receiving rFSH. CONCLUSIONS This study did not demonstrate a difference between the use of h-FSH vs r-FSH for ovarian stimulation in terms of pregnancy outcome, in good prognosis patients undergoing their first IVF-ET procedure.

Abstract
OBJECTIVE To compare the effectiveness of clomiphene citrate used alone and in combination with ethinyl E2 for the induction of ovulation in patients undergoing IUI. DESIGN Randomized, double-blind study. SETTING Four infertility treatment centers. PATIENT(S) Women aged 25-35 years with infertility of at least 2 years' duration and oligomenorrhea or amenorrhea associated with a positive menstrual response to an IM progesterone challenge. INTERVENTION(S) A total of 64 patients were randomized to treatment with CC (100 mg daily for 5 days) or CC (100 mg daily for 5 days) plus ethinyl E2 (0.05 mg daily for 5 days). MAIN OUTCOME MEASURE(S) The uterine artery pulsatility index, number of preovulatory follicles, endometrial thickness, and pregnancy rate. RESULT(S) Both treatment regimens increased FSH, LH, and 17beta-E2 levels, with no statistically significant differences. There was a statistically significant difference in endometrial thickness between the two treatment groups. No statistically significant differences were noted in pulsatility index values or in the number of preovulatory follicles. CONCLUSION(S) Ethinyl E2 can reverse the deleterious effects of CC on endometrial thickness, which may contribute to higher pregnancy rates.

Abstract
The aim of this study was to determine the effectiveness of a new highly purified urinary FSH. A total of 60 in vitro-fertilization (IVF) patients, undergoing embryo transfer (ET) for the first time, were randomly allocated into two groups: Group A (n = 30). Subcutaneous administration of urinary follicle-stimulating hormone (FSH, Fostimon 75, A.M.S.A., Italy). Group B (n = 30). Subcutaneous administration of urinary follicle-stimulating hormone (FSH, Metrodin 75 HP, Serono, Italy). Statistical analysis was performed using the chi-square test, p < 0.05 was assumed as significant. This prospective randomized clinical study in an IVF-ET program showed that both drugs were equally safe and effective. Except for the number of the high quality embryos (3.16 vs 2.9; p = 0.03) the two groups did not differ in stimulation parameters or clinical pregnancy rates per attempt and per transfer. On the other hand, a mean number of 3.56 vs 2.18 embryos were cryopreserved in group A and in group B, respectively, as a result of the high number of mature oocytes and high quality embryos. When frozen embryos cycles were included, the difference in pregnancy rate became significant.
