To investigate the effect of different planting dates and irrigation regimes on six canola cultivars, a 2-year (2014–2016) experiment was conducted at the Seed and Plant Improvement Institute of Karaj. The experiments were conducted as the factorial split-plot in a randomized complete block design including six canola cultivars (Gabriella, Brutus, Triangle, Marathon, Danube, and Natali), two irrigation regimes (fully irrigated and irrigation termination at the flowering stage) and two planting dates (October 1 and November 1). The results showed that irrigation termination from the flowering stage prevented the supply of required material for filling the seeds and the metabolism of the seed compounds and reduced the growth period of the seed. Therefore, a reduction was observed in the content of oleic and linoleic acids and proline. Also, water deficit stress caused an increase in the glucosinolate content of the seed. The response of canola cultivars was different in terms of fatty acids, so that the Natali cultivar had higher palmitic, oleic acids, and proline content compared to the other cultivars at both planting dates. Fully irrigated treatment and planting date of October 1 produced the highest amount of seed and oil yield (4659 and 2073?kg ha^?1), palmitic acid (5.5%), and proline (22.7?μmol/g) content, and the lowest glucosinolate content (13.2?mg/g). Generally, the Natali cultivar and planting date of October 1 and the fully irrigated regime are highly recommended in the studied area regarding qualitative traits and yield of canola.

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   

Volatile components of Camellia sinensis inhibit growth and biofilm formation of oral streptococci in vitro     

Hassani AS  Amirmozafari N  Ordouzadeh N  Hamdi K  Nazari R  Ghaemi A 《Pakistan journal of biological sciences: PJBS》2008,11(10):1336-1341

This study aimed to evaluate the efficacy of semi fermented and non fermented Camellia sinensis extracts (Black and Green tea) and comparison between them against Streptococcus mutans ATCC 25175, S. mitis ATCC 9811 and S. sanguis ATCC 10556 that are responsible for dental caries and bacteremias following dental manipulations. Minimum inhibitory concentrations of both tea extracts were assessed by Well diffusion and Broth dilution methods and examination of cell adherence (Biofilm inhibitory concentrations) was observed on glass slides under phase contrast microscope and colony counts from glass beads. Concentration of 1 mg mL(-1) of semi fermented tea extract was completely biofilm inhibitor but biofilm formation by these bacteria was seen 7 days after treatment with 1 mg mL(-1) of non fermented Camellia sinensis on glass beads and BIC for oral streptococci treated with this extract was 1.5, 2.5 mg mL(-1) of semi fermented and 3 mg mL(-1) of non fermented extracts had bactericidal effect on these bacteria. Semi fermented and non fermented Camellia sinensis extracts were able to prevent growth of oral streptococci. Therefore dental caries significantly reduce and the efficiency of semi fermented tea was higher due to rich content of volatile components rather than non fermented extracts.  相似文献

Motovali-Emami M  Aflatoonian MR  Fekri A  Yazdi M 《Pakistan journal of biological sciences: PJBS》2008,11(2):260-264

This study was undertaken to assess the prevalence of and epidemiological factors associated with, head lice infections in Iranian primary schools in 2006 and evaluate data on the therapeutic efficacy of lindane shampoo. A total of 40586 children (19774 boys (48.72%) and 20812 girls (51.28%)] from 198 Governmentprimary schools in Kerman, were screened for head lice between March and June 2006. The diagnosis of head lice infestation was confirmed by clinical inspection of scalp and hair for the presence of adult lice nymphal stage, or eggs (nit) by line-toothed head lice comb. All children infested with lice were treated with lindane shampoo (1% gamma benzene hexachloride). The overall prevalence of head lice infestation was 1.8%. The prevalence of infestation was significantly higher in girls (2.9%) than in boys (0.6%) (p = 0.000). The infestation rate was greater among pupils who were living in rural areas (4.6%) than in urban areas (1.5%). Of the 721 children with a positive examination result, 424 pupils (58.8%) were reported as having been infested with head lice in the previous 6 months. Mother's education level was a significant risk factor in this model (p < 0.05). At 2 weeks after the primary treatment, the success rates of treatment were 49%. Comprehensive survey in our work showed the better future of the disease and related factors. Education campaigns by health care officials, physicians and teachers are expected to be helpful for head lice control. It is essential that governments should be supported form cooperation between the school authorities and public health centers to successful control head lice infestation in primary school. Also there is an urgent need to identify safe, novel insecticides for proved efficacy.  相似文献   

Cholestatic syndromes of infancy     

Rafeey M  Golzar A  Javadzadeh A 《Pakistan journal of biological sciences: PJBS》2008,11(13):1764-1767

This study aimed to provide the analysis of clinical presentation, results of laboratory and imaging investigations as well as clinical outcome of children with cholestasis. Infants with neonatal cholestasis referred to Children's Hospital from 2002 to 2007 were participated in the study in a cross-sectional prospective study. Appropriate diagnostic criteria and tests were employed for diagnosis the underlying etiologies of neonatal cholestasis. One year mortality rate was determined. One hundred twenty one infants, 75 males and 46 females, with the mean age of 58.3 +/- 15.3 (14-120) days were enrolled in study. Jaundice (94.2%) and hepatomegaly (66.1%) were the most frequent symptom and signs on admission. Idiopathic neonatal hepatitis (36.4%), extrahepatic biliary atresia (24.8%), metabolic disease (20.7%), intrahepatic ductal paucity (10.7%), intrauterine infection (3.3%) were the most frequent causes of neonatal cholestasis. One year mortality was 5.8%. There is still not one effective and specific diagnostic method in differentiating between the causes of cholestasis in the newborns and infants. Some potentially important differences in the disease pattern, initial presentation and long-term outcome are suggested from the present study when compared to previous reports from other parts of the world.  相似文献

Effects of a blend of thyme,peppermint and eucalyptus essential oils on growth performance,serum lipid and hepatic enzyme indices,immune response and ileal morphology and microflora in broilers     

Alireza Hesabi Nameghi  Ommolbanin Edalatian  Reza Bakhshalinejad 《Journal of animal physiology and animal nutrition》2019,103(5):1388-1398

This study was conducted to evaluate the effect of a blend of essential oils (EOB) derived from thyme (Thymus vulgaris), peppermint (Mentha piperita) and eucalyptus (Eucalyptus globules) as a natural growth promoter. Five dosages (0 (CON), 50, 100, 150 and 200 ppm) of EOB were added daily to the drinking water to determine its effect on growth performance, carcass quality, blood biochemistry, immune response and ileal morphology in Ross 308 broiler chicks. A total of 500, 10‐day‐old male Ross 308 broilers were allocated into five treatments with four replicates each. Inclusion of EOB at 150 ppm improved (p < 0.05) body weight gain, feed conversion ratio and production index by 11.73, 10.81 and 24.13% compared to CON respectively. The inclusion of EOB at 100, 150 and 200 ppm increased (p < 0.05) carcass yield and thigh muscle compared to CON. Serum concentration of hepatic enzymes (alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase) was decreased while the ileal villus height and ratio of villus height to crypt depth were improved (p < 0.05) in response to inclusion of 150 and 200 ppm of EOB compared to CON. The ileal Escherichia coli count was lower and Lactobacillus count was higher in EOB‐200 and EOB‐150, respectively, compared to CON at 21 and 42 days of age (p < 0.05). Antibody titre of Newcastle, bronchitis and infectious bursal disease was linearly increased (p < 0.05) by increasing supplemental level of EOB at day 4 post‐inoculation. Our results suggested that supplementation of EOB at the 150 ppm into drinking water during day 11–42 could improve growth performance, humoral immunity and ileal morphology and microflora in broilers, and thus, EOB has merit to be used as an alternative to antibiotic growth promoters.  相似文献   

Enrichment of Adult Artemia Biomass and Squid Mantle Muscle,Dosidicus gigas,with Different Ascorbic Acid (L‐Ascorbyl‐2‐Monophosphate‐Na/Ca) Concentrations          下载免费PDF全文

L‐ascorbyl‐2‐monophosphate‐Na/Ca (AMP‐Na/Ca) was used as a vitamin C source to investigate its ascorbic acid (L‐AA) enrichment and retention in boosted Artemia biomass (AB) and squid mantle muscle (SM). Different doses of AMP‐Na/Ca (500, 1000, and 1500 AMP‐Na/Ca mg/kg) were gradually dissolved into the culture tanks at time 0 (T₀) and at each hour until Hour 6 (T₆). Samples of AB and SM were taken for AMP‐Na/Ca and L‐AA analysis at T₀, T₁, T₂, T₃, T_4, T₅, T₆, T₁₂, and T₂₄. There were no significant differences (P > 0.05) among the AB groups at T₁. The T₆ enrichment analysis for AB resulted in significant differences (P < 0.05) in the AMP‐Na/Ca content for the 1500 mg/kg treatment, in which the initial concentration (0.001 ± 0.002 mg/kg) increased by more than 16‐fold. For all AB enrichment treatments, the AMP‐Na/Ca content demonstrated a decrease (32–11%) for the T₆, T₁₂ and T₂₄ analysis. The T₁ analysis for SM at the higher AMP‐Na/Ca enrichment concentration registered 30 mg/kg of L‐AA and decreased (27.6%) at T₆. This study demonstrated that AB and SM can be boosted with AMP‐Na/Ca.  相似文献

Since 2006, the members of the molecular epidemiological working group of the European "EPIZONE" network of excellence have been generating sequence data on avian influenza and avian paramyxoviruses from both European and African sources in an attempt to more fully understand the circulation and impact of these viruses. This review presents a timely update on the epidemiological situation of these viruses based on sequence data generated during the lifetime of this project in addition to data produced by other groups during the same period. Based on this information and putting it all into a European context, recommendations for continued surveillance of these important viruses within Europe are presented.  相似文献   

Prevalence and molecular characterization of bovine Cryptosporidium in Qazvin province, Iran   总被引：1，自引：0，他引：1  

Akbar Keshavarz  Ali Haghighi  Amid Athari  Bahram Kazemi  Alireza Abadi  Ehsan Nazemalhosseini Mojarad 《Veterinary parasitology》2009,160(3-4):316-318

The aim of this study was to determine the prevalence, variability with host age, and the genotypes of species of Cryptosporidium in cattle from 15 dairy farms in Qazvin province, Iran. Fecal samples, collected from 272 cattle during May 2006 to December 2007, were characterized microscopically. Oocysts from 51 positive samples were analyzed using PCR assay of 18S SSU rRNA, restriction fragment length polymorphism (RFLP) and sequencing. We identified 72.6% of the positive samples as Cryptosporidium parvum, 17.7% as Cryptosporidium andersoni, 7.8% as Cryptosporidium bovis and 1.9% as a novel genotype of C. parvum possessing a single mutation on MboII restriction. An infection rate of 19.5% of C. parvum among 174 pre-weaned calves was significantly higher than the 3.1% among 98 post-weaned calves (P < 0.0006). This is the first report of C. bovis and the new subgenotype of C. parvum in Iranian cattle.  相似文献
