Effects of fennel (Foeniculum vulgare) essential oil of diet on some biochemical parameters and salinity stress resistance of kutum (Rutilus kutum) fry

This study was carried out to investigate the effects of different levels of fennel essential oil (Foeniculum vulgare) on some biochemical parameters and salinity stress resistance of Caspian Kutum (Rutilus kutum) fry. For this purpose, Kutum fry with an average initial weight 0.6±0.002 gr were divided randomly in 5 treatments including 0 (control), 100, 200,400 and 600 mg fennel essential oil/kg diet and fed 3 times a day at a ratio of 7-12% body weight for 60 days. At the end of the experiment, biochemical parameters and salinity stress resistance were assessed. Results of serum biochemical analyze showed that the highest level of total protein and globulin was observed in 600 mg fennel essential oil/kg diet. The highest level of albumin and cholesterol was observed in 100 and 400 mg fennel essential oil/kg diet and the highest level of triglyceride, glucose and cortisol was observed in control (p<0.05). Results of salinity stress (6, 13 and 20 g/l) showed that 100 and 400 mg fennel essential oil/kg diet treatments showed the lowest response to stress and there were the lowest changes in cortisol and glucose levels before and after stress compare to control. Highest survival was observed in 100 and 400 mg fennel essential oil/kg diet. In conclusion results suggested that Fennel essential oil can improve immune system of fries by promoting biochemical parameters (total protein, albumin, globulin, triglyceride, glucose and cortisol). Also plays important role in increasing stress resistance of Kutum fry and the best operation is related to 100 mg fennel essential oil/kg diet

Correlation between Gingival Expression of STAT1 and Chronic Periodontitis

Background: Periodontal disease is a most common inflammatory disease of periodontium. A wide variety of cytokines, chemokines and receptors are synthesized by gingival fibroblasts and inflammatory cells. Signal Transducer and Activator of Transcription-1 (STAT)-1 is a transcription factor that plays a key role in the process of intracellular signal transduction through the JAK-STAT pathway in response to inflammatory cytokines, Therefore plays an important role in inflammatory diseases. So the aim of this study was to determine the correlation between STAT1 gingival gene expression and chronic periodontitis. Materials and Methods: For this purpose, gingival tissue sample were collected from 20 individuals with clinically healthy gingiva and 25 patients with moderate to severe chronic periodontitis. After homogenizing the gingival tissues, RNA was extracted by RNA isolation kit. After synthesis of cDNA, expression of STAT1 was evaluated by Real-time PCR. Results: Higher expression of STAT1 was found in chronic periodontitis in comparison to clinically healthy gingiva (P<0.001). Conclusion: In this study, STAT1 mRNA was significantly up-regulated in chronic periodontitis tissues as compared to healthy control tissues. These results suggest that the modulation of STAT1 expression may play an important role in the pathogenesis of the periodontal inflammatory process

An investigation on Vibrionaceae family of bacteria as probiotic factors in shrimp culture

We investigated the effects of Vibrionaceae family of bacteria as probiotics in the process of growth and survival rate of shrimp during propagation stages. Bacterial flora were extracted from seawater, culture farms, shrimp culture farms and sludge of private propagation farms. Different bacteria such as Vibrio alginolyticus (serotype 1-4), Vibrio splendidus I, Vibrio fluvialis II, Vibrio anguillarum I, Vibrio costicul, Vibrio vulnificaus, Vibrio nereis, Vibrio camplbelli, Vibrio natriegens, Vibrio proteolyticus, Vibrio plegius II ,Vibrio fischeri, Aeromonas hydrophila, Aeromonas schuberti, Aeromonas salmonisida, Aeromonas veronii were isolated, identified and lyophilized. These bacteria were used in different experiments on shrimp life cycle stages while the shrimps were being fed on live food such as Chaetoceros, Skeletonema and Tetraselmis algae. Vibrio alginolyticus (serotype 1) with 107 cells/ml increased proliferation of Tetraselmis sp to 71 % in 6 days compared to the control experiment. Also Vibrio alginolyticus (serotype 4) with 105 cells/in' increased Tetraselmis sp. production to 389% in 6 days compared to control. Vibrio splendidus I was also found to be able to increase shrimp fork length in postlarvae stage 3 up to 23% as compared to control. Vibrio alginolyticus and Vibrio fischeri increased survival, fork lenght and body weight of green tiger shrimp in postlarvae stage significantly (P<0.05)

The effect of photoperiod on stomach and intestinal digestive enzymes in rainbow trout (Oncorhynchus mykiss) larvae and juvenile

This study investigated the ontogeny of some digestive enzyme and explored the effects of photoperiod on stomach (pepsin) and intestine enzyme activity (alkaline phosphatase and Namino peptidase) in rainbow trout (Oncorhynchus mykiss) larvae juvenile. About 3600 larval rainbow trout in first feeding (18 days after hatching) with an average initial weight 119±0.009 mg were distributed in plastic tanks in four treatments (300 larvae in each replicate). Four light treatments consisting of 14 to 10 h, 10 to 14 h, 4 to 20 h and 24 to 0 h (light: dark), were compared in triplicates for 6 weeks. Finally, a random sampling from larvae was undertaken on days 1, 3, 5, 8, 10, 15, 20, 25, 30, 39 and 44 days after the onset of first feeding. According to the results, the digestive enzymes activity in fish larvae and juveniles had a similar change trend with age at all photoperiods. In addition, at the end of experiment, the specific activity of pepsin and Namino peptidase were the highest in 24h Light treatment, but there was no significant difference in specific activities of alkaline phosphatase (p>0.05). The results demonstrated that growth and digestive enzymes activity of rainbow trout larvae and juvenile are improved by applying of longer photoperiod in rearing conditions

Association between TNF-α promoter G-308A and G-238A polymorphisms and obesity

Tumor necrosis factor-α (TNF-α), an adipokine, is produced in adipocytes, and the elevation of its levels has been linked to obesity and insulin resistance in some population. In this study the relationship between TNF-α promoter gene polymorphism and obesity in an Iranian population has been studied. Subjects were randomly selected from Tehran Cohort Lipid and Glucose Study. Adult participants placed in three groups according to their body mass index (BMI): BMI < 25, 25 ≤ BMI < 30, BMI ≥ 30 and under-18 subjects placed in two groups, under 85th percentile BMI and above 85th percentile. Finally, 244 persons were selected for G-308A and G-238A polymorphisms analysis. The FBS, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglyceride, cholesterol levels and blood pressure and HOMA of all subjects were measured. The polymorphism −308 and −238 were revealed by restriction fragment length polymorphism (RFLP; NCOI and MSPI) after the promoter site was amplified by PCR. The allele frequency of TNF-α polymorphism was in the Hardy–Weinberg equilibrium. There was no relation between BMI and the frequency of this allele. The fact that there is no association between G-308A and G-238A TNF-α promoter polymorphisms and obesity probably shows that it is not an important risk factor for obesity and consequently for cardiovascular disease

Synthesis and Characterization of Tetracycline Loaded Methionine-Coated NiFe2O4 Nanoparticles for Anticancer and Antibacterial Applications

In the present study, nickel ferrite (NiFe(2)O(4))-based smart magnetic nanoparticles were fabricated and coated with methionine. Physiochemical characterization of the obtained Met-NiFe(2)O(4) nanoparticles revealed the presence of methionine coating over the nanoparticle surface. Drug release study indicated that Tet-Met-NiFe(2)O(4) nanoparticles possess pH-responsive controlled drug release behavior for tetracycline (Tet). The drug loading content for Tet was found to be 0.27 mg/L of nanoparticles. In vitro cytotoxicity test showed that the Met-NiFe(2)O(4) nanoparticles is biocompatible. Moreover, this magnetic nanostructured material shown strong anticancer property as these nanomaterials significantly reduced the viability of A375 cells when compared to free Tet solution. In addition, Tet-Met-NiFe(2)O(4) nanoparticles also showed strong antibacterial activity against different bacterial pathogens

Up-Regulation of Tmevpg1 and Rmrp LncRNA Levels in Splenocytes and Brain of Mouse with Experimental Autoimmune Encephalomyelitis

Background: Two long noncoding (lnc) RNAs, which have been recognized as Tmevpg1/Ifng-AS1/NeST and Rmrp play indispensable roles in the differentiation of TH1 and TH17, respectively. The aim of the present scientific study was to analyze the expression levels of the aforementioned lncRNAs in experimental autoimmune encephalomyelitis (EAE) as an animal model for multiple sclerosis (MS).Materials and Methods: Initially, EAE was induced in C57BL/6 mice via immunization by using MOG peptide. The leukocyte infiltration rate and demyelination of neuronal axons were determined. Secondly, the expression levels of Tmevpg1, Rmrp, Tbx21, and Rorc were analyzed in the cultured splenocytes and brain lysates, by using Real-Time PCR assay; eventually, the levels of interferon-gamma and interleukin-17 evaluated by ELISA.Results: Gene expression analysis revealed that Rorc expression in the splenocytes of EAE mice in comparison to the controls was elevated; however, Tbx21 expression did not show any significant difference. Tmevpg1 and Rmrp levels increased in the splenocytes of EAE mice (4.48 times and 39.70 times, respectively, p = 0.0001). Besides, in the brain lysate, the entire genes that have been mentioned were higher than the controls (Tmevpg1: 3.35 times p = 0.02 and Rmrp 11.21 times, p = 0.0001).Conclusion: The marked up-regulation in Tmevpg1 and Rmrp transcripts suggested the essential roles of lncRNAs in the pathogenesis of EAE and multiple sclerosis indeed. Further investigations are necessary to evaluate the values of these lncRNAs as the target for the therapy or molecular marker for disease monitoring

Sagittal spinopelvic alignment in asymptomatic iranian adults aged 18 to 40 years

Background: Recent studies have revealed the increasing importance of sagittal spinopelvic alignment. Knowing the values of sagittal spinopelvic parameters, which are affected by ethnicity, is essential in the normal asymptomatic population. In the current study, these parameters were measured in a sample of asymptomatic Iranian population. Methods: Seventy asymptomatic participants without complaint of musculoskeletal problems were enrolled. They had no complaint about musculoskeletal problems. Lateral full-length spinal and pelvic x-rays were taken. The following parameters were measured on x-rays and presented as mean ± standard deviation: pelvic incidence (PI), sacral slope (SS), pelvic tilt (PT), lumbar lordosis (LL), thoracic kyphosis (TK), lumbar tilt (LT) and thoracic tilt (TT). Results: The population consisted of 37 males and 33 females aged 26.6 ± 4.27 years. The mean values of PI, SS, PT, LL, TK, LT, and TT were 44.5 ± 10.1, 35.4 ± 6.7, 9.1 ± 7.9, 41.9 ± 14.7, 28.8 ± 8.3, 11.9 ± 7.4 and -7.5 ± 5.7 (median: -10; 5th percentile: -14; 95th percentile: 4.4) degrees, respectively. The variables were similar between males and females except for LL which was significantly higher in females (37.8 ± 16.5 versus 46.5 ± 11; P = 0.013). In addition, the linear regression model revealed age to be independently related with PI (beta = 0.344; P = 0.004) and PT (beta = 0.366; P = 0.002). PI (r = 0.344, P = 0.004) and PT (r = 0.359, P = 0.002) were positively correlated with age. Additionally, PI was positively correlated to SS, PT and LL and negatively to TT. Conclusion: These findings may be used as referential values for sagittal spinopelvic parameters in the Iranian population. The positive correlation of PI with age questions the constancy of PI throughout life. However, larger studies are required. © 2020 The Author(s).
