Background: Multiple sclerosis (MS) is known as a progressive central nervous system inflammatory disease. Certain factors, such as interleukins, inflammatory cells, and oxidative stress are supposed to involve in MS etiology. Because of the important role of oxidative stress, antioxidant therapy for MS has received more attention. Although coenzyme Q10 (CoQ10) acts as an antioxidant, there is a lack of enough research on its effects on MS. Therefore, the present research was designed. Methods: C57BL/6 female adult mice (n = 30) were used in this study. The animals were randomly divided into trial and control groups. To induce MS, routine procedure for experimental autoimmune encephalomyelitis (EAE) was used, and scoring was performed based on clinical signs. By detecting score one, CoQ10 administration was started (10 mg/kg/three weeks). By using ELISA and real-time PCR, the brain levels of TNF-, IL-10, IL-4, and IL-12 were studied. Statistical tests were used to analyze the data and the P value less than 0.05 was considered to be significant. Results: Clinical symptoms in EAE animals were significantly decreased (P<0.05) as compared to control ones. In addition, the level of the TNF- was significantly decreased following CoQ10 administration versus IL-10. The ratio of TH1/TH2 interleukins in treated animals was significantly less than that in non-treated animals (P<0.01). Conclusion: Our findings showed that CoQ10 is capable of suppressing the inflammatory pathway of MS. Key Words: Experimental autoimmune encephalomyelitis (EAE), Multiple Sclerosis (MS), Coenzyme Q10 (CoQ10)  相似文献

Sarkaki A  Amani R  Badavi M  Moghaddam AZ  Aligholi H  Safahani M  Haghighizadeh MH 《Pakistan journal of biological sciences: PJBS》2008,11(8):1114-1119

The aim of this study was to evaluate the effects of different doses of dietary soy meals (with or without isoflavone) on dementia in ovariectomized (OVX) animal model of Alzheimer's disease. Female Wistar's rats with the exception of intact group were ovariectomized at the first line of study. Animals were divided into 2 main groups: control (c) and pre-treatment groups. Animals in pre-treatment groups received one of five types of diet during four weeks prior Nucleus Basalis Magnocellularis (NBM) electrical lesion normal diet (0), 10 g soy with isoflavone (10), 20 g soy with isoflavone (20), 10 g soy without isoflavone (-10) and 20 g soy without isoflavone (-20) in 30 g daily diet. The spatial learning and memory were tested using Morris water maze after electrical lesion. Rats were trained in water maze to find a hidden escape Platform. Rats received 6 blocks that each block consisted of 3 trials. Following acquisition trials, one probe trial was conducted in which the platform was removed. Soy meal diet (with or without isoflavone) in ovariectomized rats with Alzheimer's disease caused improvement of performance across 18 trials of Acquisition. Our results suggest that soy meal is a potential alternative to estrogen in the prevention and treatment of Alzheimer's disease.  相似文献

Osteopontin gene polymorphism association with milk traits and its expression analysis in milk of riverine buffalo     

Sidra Manzoor  Asif Nadeem  Javed Maryam  Abu Saeed Hashmi  Muhammad Imran  Masroor Ellahi Babar 《Tropical animal health and production》2018,50(2):275-281

Osteopontin gene is regarded as a plausible candidate in mammary gland differentiation and development, expressed by variety of cells, tissues, and biological fluids including milk. The current study was performed in two phases. In the first phase, Osteopontin gene polymorphisms were identified and associated with milk composition such as ash, milk fat, SNF, lactose, and protein. In the second phase, milk samples from five healthy mastitis-free Nili Ravi buffaloes were analyzed for expression of Osteopontin gene at transition (day 15), mid (day 90), and end (day 250) stage of their second lactation. Briefly, blood samples were collected from Nili Ravi buffalo to isolate the genomic DNA, specific primers were designed for PCR amplification. The amplified PCR products were sequenced bi-directionally. Six polymorphisms were identified in the coding region and four in the intronic region of the gene. The results showed that SNP g.38329758 T > C causing substitution of valine to alanine (V127A) was associated with high milk protein. For mRNA expression analysis, somatic cells were separated from milk samples for RNA isolation. Analysis of differential gene expression data has permitted us to illustrate the expression pattern of osteopontin gene in lactating buffalo. The Osteopontin gene was found to be transcribed among all three lactation stages, but expression was observed with the highest value (fold change) in peak lactation and remained elevated till the end of lactation. Identified gene marker may be helpful for the prediction of superior animal for selection. The presented study also gave an insight into the genetic screening and lactation biology of riverine buffalo, offering direction for future research in lactating buffalo.  相似文献   

Comparison of Growth and Fatty Acids Composition of Freshwater Rotifer, Brachionus calyciflorus Pallas, Fed with Two Types of Microalgae at Different Concentrations     

Abdolmohammad Abedian  Kennari  Nasrollah  Ahmadifard  Jafar  Seyfabadi Maryam Fallahi  Kapourchali 《Journal of the World Aquaculture Society》2008,39(2):235-242

As algae and their concentrations are important factors for mass culture of rotifer, two experiments were conducted to find the effects of two types of algae, Chlorella sp. and Scenedesmus obliquus, and three concentration of chosen algae (0.1 × 10⁶, 1 × 10⁶, and 10 × 10⁶ cells/mL) on growth and fatty acid composition of freshwater rotifer, Brachionus calyciflorus. The result of the first experiment showed that the maximum density of rotifer was significantly higher when fed with Chlorella sp. (478 individuals/mL) than fed with S. obliquus (328 individuals/mL). Mean population growth rate (r) was 0.61 and 0.44 for rotifer fed with Chlorella sp. and S. obliquus, respectively. The amount of highly unsaturated fatty acid (HUFA) in rotifer fed with Chlorella sp. (3.32%) was relatively more than those fed with S. obliquus (2.65%). Then, Chlorella sp. was selected based on better performance. In the second experiment, the maximum rotifer density of 108 ± 8, 489 ± 47, and 493 ± 51 individuals/mL was reached after 5 d for the respective Chlorella sp. concentrations; at concentration of 10 × 10⁶ cells/mL, the maximum density of 1820 ± 47 individuals/mL was obtained. Mean growth rate at mentioned concentrations was 0.18, 0.42, and 0.51/d, respectively. Increase in algal concentration was associated with a relative increase in HUFA and decrease in monounsaturated fatty acid.  相似文献   

Sugarcane Bagasse Biochar: Preparation,Characterization, and Its Effects on Soil Properties and Zinc Sorption-desorption     

Maryam Haghighatjou 《Communications in Soil Science and Plant Analysis》2020,51(10):1391-1405

ABSTRACT

Application of alkaline biochar has been proposed as an alternative to lime for remediation of acidic soils. However, questions remain as to how the reactions and fate of metals in acidic soils can be affected by biochar amendment. To find out how biochar addition might affect sorption-desorption behavior of zinc (Zn) in acidic soils, a soil with an initial pH value of 4.67 was treated with different levels [0 (control), 1%, 3%, and 6%] of biochar produced from pyrolysis of sugarcane bagasse at 600°C and incubated for 30 days under 80% of water holding capacity. At the end of the incubation period, important soil chemical properties were measured and batch isotherm experiments were performed to determine soil Zn sorption-desorption parameters. The results showed that the biochar-amended soils had higher pH values (up to 2.5 pH units), electrical conductivity (up to 2.66 times), and cation exchange capacities (up to 42%) relative to the un-amended acidic soil. Biochar addition also led to significant enhancements in soil exchangeable calcium, magnesium, sodium, and potassium cations. Both sorption and desorption isotherm experiments revealed the significantly higher capacity of the biochar-amended soils to retain Zn than that of the control. Moreover, the biochar-amended soils exhibited a higher affinity for Zn sorption than did the un-amended acidic one. It can be concluded that biochar derived from sugarcane bagasse could serve as a good amendment material to reclaim acidic soils and to reduce Zn mobility and toxicity in acidic metal-contaminated soils.  相似文献   

Dietary sour lemon (Citrus limon) peel essential oil supplementation for reduction of deltamethrin‐induced stress in rainbow trout (Oncorhynchus mykiss)     

Maryam Amiri Resketi  Sakineh Yeganeh  Khosro Jani Khalili 《Journal of the World Aquaculture Society》2021,52(1):105-123

The purpose of this study was to investigate the dietary effects of using essential oil from sour lemon peel (Citrus limon) on growth performance, carcass composition, blood and serum parameters, and liver enzymes of juvenile rainbow trout (Oncorhynchus mykiss) exposed to deltamethrin (DMN) pesticide. Treatments with no lemon peel essential oil (LPEO) and without DMN (control), as well as four treatments with 10% of 96‐h lethal concentration of DMN were prepared with dietary supplementation of LPEO (zero, 200, 400, and 600 mg/kg). Trout juveniles (95.12 ± 0.53 g) were randomly allocated to the treatments (each with three replicates). The results showed that dietary LPEO inclusion improved fish growth parameters in the DMN‐containing treatments. The highest fat content was found in zero LPEO treatment with no DMN while it was lowest in DMN treatments containing 400 and 600 mg/kg of LPEO. Carcass protein content was the highest in DMN treatment with 400 mg/kg of LPEO. Blood and serum biochemical parameters showed statistical differences between no LPEO treatment with DMN exposure and those detected in the control fish (p < .05). Overall, the results indicate that dietary inclusion of LPEO at 400 mg/kg level can decrease some negative effects of DMN exposure.  相似文献   

Lemon,Citrus aurantifolia,peel and Bacillus licheniformis protected common carp,Cyprinus carpio,from Aeromonas hydrophila infection by improving the humoral and skin mucosal immunity,and antioxidative responses     

Faeze Sadeghi  Ehsan Ahmadifar  Mohsen Shahriari Moghadam  Maryam Ghiyasi  Mahmoud A. O. Dawood  Sevdan Yilmaz 《Journal of the World Aquaculture Society》2021,52(1):124-137

The role of dietary lemon peel (LM) and/or Bacillus licheniformis (BL) on the growth, immunity, and resistance against Aeromonas hydrophila in common carp, Cyprinus carpio was investigated in this study. LM and BL were included in diets at 0% (T0), 10⁸ CFU/g BL (T1), 1.5% LM and 10⁸ CFU/g BL (T2), and 3% LM and 10⁸ CFU/g BL (T3). Fish fed with T1, T2, or T3 had higher weight gain, specific growth rate, white blood cells count, and blood total protein with lower feed conversion ratio than T0 group (p < .05). The albumin increased significantly (p < .05) in fish fed both BL and LM (T3). The serum superoxide dismutase (SOD), catalase, lysozyme, and bactericidal activities were significantly increased in fish fed both BL and LM (T2 and T3), while serum glutathione peroxidase increased in fish fed BL (T2) (p < .05). Fish fed T1, T2, and T3 diets displayed higher SOD and lower malondialdehyde than fish fed T0 (p < .05). After the A. hydrophila challenge, the mortality rate was significantly lower in T1, T2, and T3 groups than the T0 group (p < .05). The obtained results revealed that LM and BL could be used to increase resistance against A. hydrophila infection in carp. However, further field studies should be performed to confirm the obtained results.  相似文献   

Pigmentation and growth performance in the blue gourami,Trichogaster trichopterus,fed marigold,Calendula officinalis,powder, a natural carotenoid source     

Maryam Jorjani  Mostafa Sharif Rohani  Amin Mirhashemi Rostami  Harry Ako  Aileen Tan Shau Hwai 《Journal of the World Aquaculture Society》2019,50(4):789-799

The present study aimed to determine the effects of different levels of marigold, Calendula officinalis, powder, 0 (control), 0.5% (M0.5), 1.5% (M1.5), and 2.5% (M2.5), on pigmentation and growth performance of the blue gourami after a 70‐day trial. At the end of the experiment, no significant differences (p > 0.05) were found in fish growth performance and body compositions. Color parameters (L*, a*, and b*) were weekly evaluated by examining a point posterior to the fish operculum. The marigold‐fed fish were darker than the control fish at Weeks 9 and 10. Yellowness intensity of the M2.5 was significantly higher than the other treatments at Week 9. Skin and caudal fin total carotenoids, astaxanthin, canthaxanthin, and β‐carotene contents of the treatment M2.5 were significantly different (p < 0.05) compared to the other treatments. Muscle total carotenoids, astaxanthin, and canthaxanthin contents of the marigold‐treated fish were significantly (p < 0.05) higher than the control group. Muscle β‐carotene contents of the treatments M1.5 and M2.5 were significantly (p < 0.05) higher than the control group. This study shows that marigold powder may be considered an efficient natural carotenoid source for pigmentation in blue gourami.  相似文献   

The effects of onion and salt treatments on essential oil content and composition of Rosa damascena Mill     

Tayebeh Shamspur  Maryam MohamadiAli Mostafavi 《Industrial Crops and Products》2012,37(1):451-456

Due to the low oil content of Rosa damascena Mill., on one hand, and the wide spectrum of its application, on the other hand, it is desirable to find ways to increase the oil yield and also its quality. Therefore, in the present study the effects of chopped onion (1.0, 1.5, 2.0 and 4.0 g per 220 g of rose flower) and sodium chloride (11.0, 15.5, 22.0 and 30.0 g per 220 g of rose flower) which were added to rose flowers before distillation, were investigated on the quality and quantity of the oil. The quantity was measured as the ratio of oil to rose flower (w/w, %) and the quality was evaluated using the oil composition especially the content of monoterpene alcohols and hydrocarbons. Compared with corresponding control sample, treating with 1.5 g of chopped onion increased the oil content by 41% but it resulted in a lower quality; whereas in the presence of 1.0 g of onion, an increase of 30% and a decrease of 18% were observed in the percentage of monoterpene alcohols and hydrocarbons, respectively without any considerable change in the oil content. However, the effect of sodium chloride was somehow different from that of onion; such that in the optimal amount (22.0 g), the salt had no considerable effect on the quality but an increase of 21% in the oil yield.  相似文献
