Zingiber officinale extends Drosophila melanogaster life span in xenobiotic-induced oxidative stress conditions

Frontiers in Biology 2018年第2期13卷 130-136页

BACKGRoUND： The possibility of dietary ginger to enhance oxidative stress resistance and to extend life span was studied on Drosophila melanogaster. METHoDS： oxidative stress was induced by a reducing agent dithiothreitol. Experimental groups of male D. melanogaster were cultured on media containing： 1） no additive; 2） dithiothreitol, added into the nutritional mixture to the final concentration of 10 mM; 3） 25 mg of ginger powder g^-1 of the nutritional mixture; and 4） 10 mM ofdithiothreitol and 25 mg of ginger powder g l of the nutritional mixture. The number of alive fruit flies was inspected daily, and mean life span was determined for each experimental group. RESULTS： The addition of dithiothreitol to D. melanogaster nutritional mixture was established to result in an increase in concentration of two markers of oxidative stress conditions （thiobarbituric acid reactive substances as products of lipid peroxidation and carbonylated proteins as products of protein oxidation） in fly tissues. It was followed by significant reduction of mean life span and maximum life span of the last 10% of flies. Plant preparation, being added simultaneously with dithiothreitol, significantly diminished the negative effects of this xenobiotic. In conditions of additional stress load induced by hydrogen peroxide or high temperature, survival of insects treated with dithiothreitol on the background of ginger powder was the highest. CoNCLUSIoNS： Thus, the presented data give the evidence that ginger preparations can reduce oxidative stress outcomes and significantly increase the life expectancy of fruit flies in stress conditions.

Influence of Magnetic Field and Lighting during the Creation Process of Nanohybrid Semiconductor-Nematic Structures on Their Impedance and Photo Response

Journal of Materials Science & Technology 2011年第11期27卷 973-978页

作者： Fedir Ivashchyshyn Ivan Grygorchak olena Sudakova Igor Bordun Miroslav Micov Lviv Polytechnic National University 12 Bandera Str. Lviv 79013 Ukraine

In this work, for the first time, photosensitive nanostructures with alternate semiconductor and magnetic oriented nematic molecular nanolayers were obtained. The established dependency on the ordering type of kinetic and optical properties is deserving attention. For the first time, the notion of ＇rotary＇ polaron in such structures is introduced and microscopic model is created, which explains band structure transformation. The model is well coordinated with experimental optical data, which, at the same time, indicate the prospects of application of materials obtained due to the intercalation engineering for photoenergetics.

Fuzzy Tuned PID Controller for Envisioned Agricultural Manipulator

International Journal of Automation and computing 2021年第4期18卷 568-580页

The implementation of image-based phenotyping systems has become an important aspect of crop and plant science research which has shown tremendous growth over the years. Accurate determination of features using images requires stable imaging and very precise processing. By installing a camera on a mechanical arm driven by motor, the maintenance of accuracy and stability becomes non-trivial. As per the state-of-the-art, the issue of external camera shake incurred due to vibration is a great concern in capturing accurate images, which may be induced by the driving motor of the manipulator. So, there is a requirement for a stable active controller for sufficient vibration attenuation of the manipulator. However, there are very few reports in agricultural practices which use control algorithms. Although, many control strategies have been utilized to control the vibration in manipulators associated to various applications, no control strategy with validated stability has been provided to control the vibration in such envisioned agricultural manipulator with simple low-cost hardware devices with the compensation of non-linearities. So, in this work, the combination of proportional-integral-differential(PID) control with type-2 fuzzy logic(T2-F-PID) is implemented for vibration control. The validation of the controller stability using Lyapunov analysis is established. A torsional actuator(TA) is applied for mitigating torsional vibration, which is a new contribution in the area of agricultural manipulators. Also, to prove the effectiveness of the controller, the vibration attenuation results with T2-F-PID is compared with conventional PD/PID controllers, and a type-1 fuzzy PID(T1-F-PID) controller.

Background Presently, approaches for the early treatment of pathological anxiety in patients with chronic non-communicable diseases are lacking, thus delaying the initiation of symptom management at the early onset of the illness. Proactive psychological and psychiatric support, to alleviate subclinical symptoms of anxiety and to improve the quality of life in patients with chronic non-communicable diseases, is a promising candidate for the role of such *** To investigate and determine the effectiveness of proactive psychological and psychiatric support for alleviating subclinical symptoms of anxiety and improving quality of life, in patients with chronic non-communicable *** The study design was a monocentric randomised controlled trial with parallel groups. The study, involving 193 inpatients with chronic non-communicable diseases, complied with the ethical and deontological norms in accordance with the principles set out in the Declaration of Helsinki. Instruments used in the study included the Hamilton Anxiety Scale (HAM-A) to assess subclinical symptoms, the Scale of Somatic Symptoms and the Chaban Quality of Life Scale. Block randomisation was used to randomise patients to a 2-month-long study group with a proactive counselling psychiatry model care or a control group with standard regulated treatment for chronic non-communicable diseases. The allocation ratio was 1.15:1 owing to the expectancy of a higher percentage of dropout in the intervention *** After 60 days of treatment (T2), there was a statistically significant difference in all clinical parameters between the study and control groups. The median HAM-A value differed between the groups by 4.87 points, with statistically significant lower results in the study group. The comparison of the study group’s scale values on day 1 and day 60 demonstrated statistically significant changes in all three *** our results support existing evidence for the effective
