The effect of organic fertilization on olive sapling cultivation: Vermicompost as an example

Olive sapling nursery is a growing agricultural activity in our country in the recent years. There is not an easily accessible resource about the most suitable fertilizer in sustainable agriculture of these saplings. Moreover, studies on effects of the applied fertilizers on leaves, stem and root development of olive saplings will guide the farmers who handle nursery. In this study Gemlik olive variety saplings were grown using different doses of vermicompost (0, 5, 10,20, and 40%) as the organic fertilizer added to the production material used in traditional olive sapling nursery, and one dose of chemical fertilizer (100% production material + chemical fertilizer) that has been used commonly by the producers. The nutritional elements in the leaves, stem and root of the grown saplings were analyzed. The results of the analysis of leaves, stem and roots of saplings at the 3rd and 6th months of the research were found to statistically significant. The results of totally 6 months of experiment revealed significant effects of different production materials on the analyzed parameters. In general, vermicompost usage can be avowable in terms of both to increase production material quality and development of saplings in olive sapling nursery. © 2020 Parlar Scientific Publications.

Accumulation of alpha-Synuclein in Cerebellar Purkinje Cells of Diabetic Rats and Its Potential Relationship with Inflammation and Oxidative Stress Markers

WOS: 000392134300001PubMed ID: 28133547Objective. The present study was conducted to evaluate the relationship between plasma oxidative stress markers such as malondialdehyde (MDA) and glutathione (GSH), inflammatory marker pentraxin-3 (PTX3), and cerebellar accumulation of alpha-synuclein in streptozotocin-(STZ-) induced diabetes model in rats. Methods. Twelve rats were included in the study. Diabetes (p = 6) was induced with a single intraperitoneal injection of streptozotocin (STZ, 60 mg/kg). Diabetes was verified after 48 h by measuring blood glucose levels. Six rats served as controls. Following 8 weeks, rats were sacrificed for biochemical and immunohistochemical evaluation. Results. Plasma MDA levels were significantly higher in diabetic rats when compared with the control rats (p < 0.01), while plasma GSH levels were lower in the diabetic group than in the control group (p < 0.01). Also, plasma pentraxin-3 levels were statistically higher in diabetic rats than in the control rats (p < 0.01). The analysis of cerebellar alpha-synuclein immunohistochemistry showed a significant increase in alpha-synuclein immunoexpression in the diabetic group compared to the control group (p < 0.01). Conclusion. Due to increased inflammation and oxidative stress in the chronic period of hyperglycemia linked to diabetes, there may be alpha-synuclein accumulation in the cerebellum and the plasma PTX3 levels may be assessed as an important biomarker of this situation

The Effect of Acute Allergic Reactions on Diastolic Heart Function

Purpose: Diastolic heart failure is characterized by the presence of heart failure symptoms despite preserved systolic function. Cytokines released during allergic reactions may impair diastolic heart function, either through their direct toxic effects or by inducing coronary artery spasm. The purpose of this study was to examine the effects of acute allergic reactions on diastolic heart function. Methods: Fifty patients, randomly selected from those who were admitted to the emergency room between May 2010 and December 2010 with the complaints of rash and itching, and who were subsequently diagnosed with allergic reactions based on the clinical and laboratory findings, were included in the study as the allergy group. Thirty healthy volunteers, in whom the diagnosis of allergy was ruled out based on the clinical and laboratory data, were use as the control group. Diastolic heart functions were evaluated in patients presenting with allergic reaction as well as in control subjects. Results: There was no significant difference between the two groups in terms of basal systolic functions, diameters of the cavities and wall thicknesses, and biochemical parameters. Color M mode flow progression velocities, E ratios, E/A ratios and mitral lateral annulus tissue Doppler velocities measured by echocardiography at Day 0 and Day 5 were significantly altered in the allergy group (p < 0.05). Conclusion: Impairment in diastolic functions was observed following acute allergic reactions. Acute allergic reactions could be a cause of mortality and morbidity if they lead to the development of diastolic heart failure
