Yield And Quality

This study evaluated the effects of biochar application on sodium ion accumulation, yield and quality of rice in saline-sodic soil by using a pot experiment. Rice was grown in the soil with no biochar, 15 g biochar per kilogram soil, 30 g biochar per kilogram soil and 45 g biochar per kilogram soil. The results indicated that biochar application significantly decreased sodium ion accumulation of rice plant parts, while it obviously increased rice dry biomass, grain yield and improved rice quality. The results suggested that biochar application to saline-sodic paddy soil has benefits to reduce stress and promote the increase of rice yield and quality formation in saline-sodic soil.

Physiological Characters

Salinity is one of the most important environmental factors which have a significant effect on the growth and fertility. Manganese is an essential element that plays a key role as a nutrient in many plant metabolic processes. The present study was carried out to investigate the effects of manganese (1ppm) on Yaghoti and Ghara uzum - two cultivars of grapevine - which were planted and grown under salt stress (0, 50 and 100mmol L-1 NaCl) using greenhouse and hydroponics methods. Results on saline concentration showed led to a significant decrease in length, fresh and dry weight, photosynthesis pigments content, K+ and nitrate content, and K+/Na+ ratio of the plants. It also caused a significant increase in Na+ and Cl- ion concentration and soluble sugar content in shoots and roots of both cultivars. Ghara uzum was more sensitive than Yaghoti to salinity stress. Applying manganese to the medium, resulted in low level of salinity toxicity and sodium ion accumulation in the shoots for Ghara uzum cultivar. For Yaghoti, however, the application of manganese did not reduce the sodium ion accumulation in the shoots, but increased the salinity toxicity. Our findings suggest that Ghara uzum and Yaghoti cultivars had different responses to salinity, manganese and their interaction.

Abstract Recently, we have read with great interest the article published by Ibarrola et al. (Clin. Sci. (Lond.) (2018) 132, 1471–1485), which used proteomics and immunodetection methods to show that Galectin-3 (Gal-3) down-regulated the antioxidant peroxiredoxin-4 (Prx-4) in cardiac fibroblasts. Authors concluded that ‘antioxidant activity of Prx-4 had been identified as a protein down-regulated by Gal-3. Moreover, Gal-3 induced a decrease in total antioxidant capacity which resulted in a consequent increase in peroxide levels and oxidative stress markers in cardiac fibroblasts.’ We would like to point out some results stated in the article that need further investigation and more detailed discussion to clarify certain factors involved in the protective role of Prx-4 in heart failure.

The Relationship

Parenting behaviors – specifically behaviors characterized by high control, intrusiveness, rejection, and overprotection – and effortful control have each been implicated in the development of anxiety pathology. However, little research has examined the protective role of effortful control in the relation between parenting and anxiety symptoms, specifically among adults. Thus, we sought to explore the unique and interactive effects of parenting and effortful control on anxiety among adults (N = 162). Results suggest that effortful control uniquely contributes to anxiety symptoms above and beyond that of any parenting behavior. Furthermore, effortful control acted as a moderator of the relationship between parental overprotection and anxiety, such that overprotection is associated with anxiety only in individuals with lower levels of effortful control. Implications for potential prevention and intervention efforts which specifically target effortful control are discussed. These findings underscore the importance of considering individual differences in self-regulatory abilities when examining associations between putative early-life risk factors, such as parenting, and anxiety symptoms.

The Way

Abstract. This paper aimed to assess whether differences in the way to conceive happiness, measured by the Orientations to Happiness measure, were associated with specific reactions to negative events. We hypothesized that among orientations to pleasure (portraying hedonism), to meaning (representing a eudaimonic approach to life), and to engagement (derived from the experience of flow), orientation to meaning would have displayed a stronger protective role against recent negative and potentially stressful events. After providing a validation of the Italian version of the Orientations to Happiness measure (Study 1), we performed regression analyses of the three orientations on positive and negative emotions linked to a self-relevant negative event (Study 2), and moderation analyses assessing the interactive effects of orientations to happiness and stressful events on well-being indicators (Study 3). Our findings supported the hypotheses. In Study 2, meaning was associated with positive emotions characterized by a lower activation (contentment and interest) compared to the positive emotions associated with pleasure (amusement, eagerness, and happiness). In Study 3, only meaning buffered the effect of recent potentially stressful events on satisfaction with life and positive affect. Results suggest that orientation to meaning might help individuals to better react to negative events.
