Influence of mycorrhizal fungi and biochar on nitrogen use efficiency correlated with yield and yield components of wheat

Mycorrhizal symbiosis increases mineral nutrient uptake, especially when nitrogen applies to the fields together with biochar. To evaluate the influence of the biochar application and different levels of nitrogen on nitrogen use efficiency (NUE), yield and yield components of wheat associated with arbuscular mycorrhizal fungi (AMF) A factorial experiment with in randomized complete block design with four replications was implemented for two years (2016-2018). The experimental factors included nitrogen at four levels (urea source with 46% nitrogen) 0, 50, 100 and 150 kg N/ha, Rhizophagus Irregularis inoculum at two levels (without and with application), and biochar at three levels 0, 4 and 8 ton/ha. The results demonstrated that plant inoculated with mycorrhiza inoculum combined with 4 ton/ha of biochar showed a significant increase in, root colonization (8%). The application of will be This study proves that application of 100 kg N/ha with an amount of 4 ton/ha of biochar and AMF inoculationhas a useful and effective role in the enhancement of growth and yieldof wheat

Is household food insecurity related to mothers' stress, anxiety and depression in Iran?

Food insecurity is a public health concern with pervasive effects on numerous human biological factors. In addition to physical problems, food insecurity may have adverse social and psychological impacts. The present study aimed to determine the correlations between household food insecurity and stress, anxiety, and depression in mothers living in Mashhad, Iran. In this cross-sectional study we recruited 312 mothers. We collected data on the food insecurity status of households using the Household Food Insecurity Access Scale (HFIAS) and used the Depression Anxiety Stress Scale (DASS) to assess the levels of stress, anxiety, and depression in the subjects. The prevalence rate of food insecurity was 51.9%, and the prevalence rate of stress, anxiety, and depression was 70.2%, 70.2%, and 55.1%, respectively. In the food-insecure group, 94.3% of the mothers had stress, 91.4% had anxiety, and 87.1% had depression. While in the food-secure group, 60.7%, 61.3%, and 37.3% of the mothers had stressed, anxiety, and depression, respectively. In all the analytical models, food insecurity was significantly and positively associated with stress, anxiety, and depression (P < 0.001). Our results suggested that a higher level of food insecurity correlates with extreme degrees of stress, anxiety, and depression. Therefore, the improvement of mothers' mental health in terms of stress, anxiety, and depression depends on the improvement of household food insecurity

Dietary Animal Protein vs. Plant Protein Sources in Relation to the Risk of Biliary Stone: A Case-Control Study

Dietary intake is one of the modifiable risk factors for biliary stones. In recent studies, plant protein intake is associated with a lower risk of biliary stones in comparison to animal protein intake; however, the results are contradictory. The current study aims to compare the effect of animal protein and plant protein on the formation of biliary stone in one of the gastroenterology and liver disease centers in Iran. Methods: 110 participants who had a history of biliary stone and 230 controls who were normal in terms of biliary diseases and referred to the medical center from November 2017 to October 2018 enrolled in this study. Food frequency questionnaire (FFQ) was used for the nutritional assessment; moreover, demographic and anthropometric data, habitual history and comorbidities were collected. Statistical analysis was conducted by SPSS software. Results: Plant protein consumption was significantly lower (P=0.03) and animal protein intake was significantly higher (P=0.02) among men in case compared to controls. Furthermore, the relationship between biliary stone disease and animal protein intake was significant in crude model for men (OR: 1.03, 95% CI=1.01-1.05). In addition, the risk of biliary stone was significantly lower in patients with higher consumption of plant protein (for women: OR: 0.94, 95% CI=0.89-0.99, for both sexes: OR: 0.96, 95%CI=0.93-0.99). Conclusion: The present study suggested that consumption of animal protein sources increased the risk of biliary stone, and intake of plant protein sources decreased the risk of biliary ston
