In experiment 2, control solution, L-DOPA (125 nmol), MTII (10 ng), and L-DOPA + MTII were applied to the birds. Experiments 3-9 were similar to experiment 2, except birds injected with 6-OHDA (150 nmol), SCH23390 (5 nmol), AMI-193 (5 nmol), NGB2904 (6.4 nmol), L-741,742 (6 nmol), SR141716A (6.25 µg), and AM630 (5 µg) instead of L-DOPA. Then, cumulative food intake was recorded at 30, 60, and 120 min following injection. According to the results, in comparison with the control group, dose-dependent hypophagia was observed in 3-h food-deprived neonatal layer chickens following ICV injection of MTII (2.5, 5, and 10 ng) (P 0.05). These results demonstrated that melanocortin-induced hypophagia in the neonatal layer chickens is likely mediated by D1, D2, and CB1 receptors.","PeriodicalId":36826,"journal":{"name":"Iranian Journal of Veterinary Science and Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49351465","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the present study aimed to compare some inflammatory cytokines and immunologic factors between two groups of healthy and SCK cows. Serum specimens were collected from 30 clinically healthy dairy cows on the early dry period (EDP), one week before expected calving (-1w), and one week postpartum (+1w). The animals were divided into the two groups of healthy (N=20) and SCK (N=10) based on serum β-hydroxybutyrate cut-off of 1.2 mmol/L on +1w. The concentrations of immunoglobulin G (IgG), interleukin-4 (IL-4), IL-10, interferon-γ (IFN-γ), tumor necrosis factor-α (TNF-α), and haptoglobin (Hp) were measured by enzyme-linked immunosorbent assay. The data were statistically analyzed by mixed analysis of variance and independent samples t-test using the SPSS software. The findings demonstrated that the overall levels of IL-4 (P=0.033), IL-10 (P=0.049), TNF-α (P=0.028), and Hp (P=0.018) were significantly higher in the SCK group than the control group. Furthermore, the interaction of time × SCK had a significant influence on IL-4 (P=0.028) and Hp (P=0.022) levels.

This study intended to determine whether pretreatment of adipose-derived MSCs (ASCs) with Human chorionic gonadotrophin (hCG), a glycoprotein hormone, and Vitamin E, an antioxidant, will improve their immunomodulatory ability. In this regard, ASCs were harvested from human processed lipoaspirate. LPS-induced ASCs were preconditioned with 1 mg of hCG and 600 µM of vitamin E for 24h. TSG-6, COX-2, IL-1β, and IL-6 were assessed at the mRNA level in preconditioned and control groups. ASCs were also co-cultured with peripheral blood mononuclear cells (PBMCs) in vitro to determine the functionality of these cells. Results showed that hCG and vitamin E significantly downregulate the pro-inflammatory COX-2, IL-1β, and IL-6 gene expression, while they did not significantly increase TSG-6 expression. Besides, the co-culturing of pretreated ASCs with PBMCs demonstrated that the amount of PBMCs in treated groups (with hCG and vitamin E) was significantly lower than in control groups.

In the present study, the effects of GABAB receptor agonist, baclofen, were investigated on GnRH, KiSS1, RFRP-3, and ghrelin gene expression in the hypothalamus of PCOS model rats. For induction of PCOS, female Wistar rats weighing 180-200g received intra-muscular injection of estradiol valerate. Fifteen PCOS rats in three groups received intraperitoneal injections of saline, 5, or 10 mg/kg baclofen for two weeks. The hypothalamic samples were dissected. Gene expression levels of GnRH, KiSS1, RFRP-3, and ghrelin were determined by real time qPCR method. Results revealed that baclofen significantly decreased the mean relative KiSS1 gene expression compared to PCOS group. Also, the mean relative RFRP-3 gene expression significantly increased in the baclofen-receiving rats in comparison to PCOS group. Furthermore, baclofen did not change GnRH or ghrelin mRNA levels in comparison to PCOS group. According to these results it can be concluded that in PCOS condition the GABAergic signaling pathway may suppress GnRH neural activity via down or up regulation of the intra-hypothalamic neuropeptides upstream of GnRH neurons.","PeriodicalId":36826,"journal":{"name":"Iranian Journal of Veterinary Science and Technology","volume":"13 1","pages":"42-47"},"PeriodicalIF":0.0,"publicationDate":"2021-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47314259","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To maintain biosecurity, it is important to identify the entry route of new viruses into a region and characterizing markers such as unique mutations that make viruses traceable. During a genotyping study for IBV infected commercial chicken flocks in Khorasan Razavi province, 11 viruses from 11 broiler and layer chicken flocks were detected in different cities by PCR. Sequencing of the S1 partial gene followed by phylogenetic analysis showed that eight viruses can be classified in GI-23 lineage (Is-Variant2), two viruses are classified in GI-1 lineage (Mass), and one virus is classified in GI-12 lineage (793B). Although detected viruses of GI-23 lineage are originated from Iran, seven viruses have synonymous (T954C and G1056A) and non-synonymous (C797T) mutations that have not been previously reported. It was found that the new genetic changes in Iranian IBVs of GI-23 lineage occurred in two different regions in Khorasan Razavi. In conclusion, this study indicates that the high prevalence of GI-23 lineage viruses in Iran may enhance the chance of virus mutations and the emergence of new viral strains, so effective vaccination and biosecurity measures are required to control the virus spread.","PeriodicalId":36826,"journal":{"name":"Iranian Journal of Veterinary Science and Technology","volume":"13 1","pages":"14-21"},"PeriodicalIF":0.0,"publicationDate":"2021-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48011758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
