Effects of Biodegradable Insecticides on Biofilter Bacteria: Implications for Aquaponics

Even though aquaponics is the production system that is increasingly gaining focus, there is an absence of publications studying the use of pesticides in the aquaponics. Therefore, the aim of this study was to assess negative effects of one synthetic (chlorpyrifos) and two botanical insecticides (azadirachtin and pyrethrin) to matured biofilter in plastic buckets. The effectiveness of biofilter bacteria is determined indirectly, as concentrations of ammonia, nitrites and nitrates in the water were measured at 0h, 5h, 13h, 21h, 29h, 37h, 45h and 53h after insecticides application. The results showed negative effects of azadirachtin on the first step of nitrification, as concentration of ammonia was higher comparing to other groups for almost every sample point. Negative effects on second step of nitrification and higher concentrations of nitrites in the water were also detected, but no statistical differences were observed in the present study, due to the large variation between buckets. Nitrates were lower in water treated with azadirachtin from 29 hours from start to the end of the experiment. Application of other two insecticides to biofilter did not cause any effects and showed no difference comparing to the control group.

Abstract Background The denial of death in Western society deprives young people of the tools to derive meaning from experiences of death and dying. Literature shows that death education may allow them to become familiar with this topic without causing negative effects. This article describes the effects of a death education course with adolescents, wherein participants were given the opportunity to meet palliative doctors and palliative psychologists at school and in a hospice, where they were able to converse with the families of the dying. Methods This study used mixed methods and included an evaluation of a death education intervention with longitudinal follow-up of outcomes. The course involved 87 secondary school students (experimental group) aged between 16 and 20 years. We also recruited a control group of 76 similarly-aged students to observe differences. The variables we examined were: alexithymia, representation of death, value attributed to life and spirituality. These were measured with the following instruments: the Toronto Alexithymia Scale-20, the Testoni Death Representation Scale, the Personal Meaning Profile and the Spiritual Orientation Inventory, respectively. To better understand how the students perceived the experience, we asked the experimental group to answer some open-ended questions. Their answers were analysed through thematic analysis. Results The study showed that death education and the hospice experience did not produce negative effects, but rather allowed students to decrease alexithymia, improving their ability to recognise and express emotions. Thematic analysis revealed that all participants perceived the experience as very positive. Conclusions Our findings affirm that death education programs can be successfully implemented in high schools, and that they can usefully involve local hospices and palliative care professionals, especially physicians and psychologists.

The experiment aimed to examine the impacts of an increased growth rate of ewes between three and seven months of age on udder development using ultrasound and to establish whether ultrasonography could be used to identify ewe mammary structures that may be indirect indicators of singleton growth to weaning. Udder dimensions, depths of gland cistern (GC), parenchyma (PAR) and fat pad (FP) were measured in late pregnancy (P107), early lactation (L29), and at weaning (L100) in 59 single-bearing yearling ewes selected from two treatments. The ‘heavy’ group (n = 31) was preferentially fed prior to breeding achieving an average breeding live-weight of 47.9 ± 0.38 kg at seven months of age. The ‘control’ group (n = 28) had an average breeding live-weight of 44.9 ± 0.49 kg. Udder dimensions, GC, PAR and FP did not differ between treatments. Lamb growth to L100 was positively associated (p < 0.05) with PAR at P107 and GC at L29. There was no evidence of negative effects of the live-weight gain treatments on udder development of yearling ewes as measured by ultrasonography. The results suggest that this ultrasound method has the potential to identify pregnant yearling ewes which would wean heavier singletons.

Cortical Cytoskeleton

Altered external mechanical loading during spaceflights causes negative effects on muscular and cardiovascular systems. The aim of the study was estimation of the cortical cytoskeleton statement of the skeletal muscle cells and cardiomyocytes. The state of the cortical cytoskeleton in C57BL6J mice soleus, tibialis anterior muscle fibers, and left ventricle cardiomyocytes was investigated after 30-day 2- g centrifugation (“2- g” group) and within 12 h after its completion (“2- g + 12-h” group). We used atomic force microscopy for estimating cell's transverse stiffness, Western blotting for measuring protein content, and RT-PCR for estimating their expression level. The transverse stiffness significantly decreased in cardiomyocytes (by 16%) and increased in skeletal muscles fibers (by 35% for soleus and by 29% for tibialis anterior muscle fibers) in animals of the 2-g group (compared with the control group). For cardiomyocytes, we found that, in the 2- g + 12-h group, α-actinin-1 content decreased in the membranous fraction (by 27%) and increased in cytoplasmic fraction (by 28%) of proteins (compared with the levels in the 2- g group). But for skeletal muscle fibers, similar changes were noted for α-actinin-4, but not for α-actinin-1. In conclusion, we showed that the different isoforms of α-actinins dissociate from cortical cytoskeleton under increased/decreased of mechanical load.

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The quiet eye (QE) represents the time needed to cognitively process information being fixated or tracked and to focus attention on the demands of the task (Vickers, 2009). Research indicates that an optimal combination of QE, attentional control, and gaze behavior is linked with superior skill execution (Harle and Vickers, 2001), and that the successful integration of these attentional behaviors may also combat the negative effects that anxiety can have on performance (e.g., Vine and Wilson, 2011). To advance the research on QE training in pressurized interceptive timing tasks (Vickers, 2016), this mixed-method study explored how QE training impacted the hitting performances of Division I baseball players during a pressure situation. The results showed that, despite experiencing more overall anxiety, the QE group maintained performance under pressure. A main effect for group also approached significance, with the QE group nearly outperforming the control group. However, this difference was not statistically significant. Regardless, analyses of the participants' written feedback indicated that the QE group reported greater task-focus, less distractibility, improved pitch perception, and reduced muscle tension. Taken together, these findings provide strong support for implementing QE training in interceptive timing tasks, particularly as it relates to preserving performance under pressure.

Abstract Objectives Nausea and vomiting have psychological negative effects on some pregnant women during gestation. Different strategies have been used for the treatment of nausea and vomiting during pregnancy, such as acupressure and psychological interventions. This study was conducted to evaluate the effects of psychological counseling and acupressure based on couple therapy procedures on vomiting and nausea in pregnant women in Iran. Methods Two hundred and eight women were divided into four groups (n=52): 1) they did not any intervention (control group), 2) they received the psychological intervention, 3) they received acupressure intervention, and 4) they received a combination of psychological + acupressure interventions. To investigate the effects of interventions on nausea and vomiting, the Rhodes index of nausea, vomiting and retching were used. The counseling period has lasted for 4 weeks. The pressure intervention on the site was conducted in clockwise form for 1 min and anticlockwise form for another 1 min. Results Groups did not have a significant difference for abortion and income (p>0.05). The effects of counseling, and acupressure interventions on severity and period of vomiting and nausea were not significant (p>0.05), but the intervention based on counseling and acupressure decreased severity of vomiting and nausea (p<0.05). Conclusions The intervention based on counseling and acupressure could not reduce nausea and vomiting during the gestation, but the intervention based on a combination of both decreased nausea and vomiting. It can be suggested to apply an intervention based on a combination of counseling and acupressure in short-time period for decreasing nausea and vomiting in women during pregnancy.

AbstractCadmium (Cd) and diazinon (DZN) are known to be environmental risk factors for various bone diseases including osteoporosis. Selenium (Se), an essential constituent of many antioxidant enzymes, has in higher concentrations negative effects on the bone. The present study was aimed to investigate possible changes in femoral bone of adult male rats after their acute and subchronic exposures to Cd, DZN and Se. A total of 30 male Wistar rats were randomized into three experimental groups. The rats in the group A (4-months-old) were injected intraperitoneally with a mixture of 2 mg CdCl2 kg−1, 20 mg DZN kg−1 and 2 mg Na2SeO3 kg−1 body weight and killed 36 h after xenobiotics had been injected. In the group B, young males (1-month-old) were administered with a combination of 30 mg CdCl2 L−1, 40 mg DZN L−1 and 5 mg Na2SeO3 L−1 in their drinking water, for 90 days. Ten 4-months-old males without toxicant supplementation served as a control group (C). After treatment period, detailed histological analysis of femoral bone was performed in each group. Our results revealed apparent osteoporotic symptoms (resorption lacunae, osteoporotic fractures) in rats from groups A and B. Moreover, histomorphometrical evaluation showed reduced bone vascularization (constricted primary osteons’ vascular canals and Haversian canals) and weakness mechanical properties of bones (smaller size of the secondary osteons) in these rats in comparison with those of the control group. Our study demonstrates for the first time that acute and subchronic co-administrations to Cd, DZN and Se induce evident manifestation characteristics of osteoporosis in male rats.

Experimental Group

To study the possibility and effectiveness of using succinylated gelatin (SG) for injecting endoscopic hemostasis. Material and methods. 70 albino non-linear rats. 0.5 ml of the solution has been injected into the anterior wall of the stomach with a syringe after laparotomy. A mixture of 0.9 % NaCl solution and epinephrine hydrothartrate (1.8 mg/1 ml) has been used in a ratio of 1:20 for the control group (35 animals). A mixture of a solution of SG (40 mg/1000 ml of injection water) and epinephrine hydrothartrate (1.8 mg/1 ml) in a ratio of 1:20 for the experimental group (35 animals). Right after the injection and in 1, 3, 6, 12 hours, after laparotomy, the stomach wall has been taken for histological examination, during which the thickness of the stomach wall (TSW) has been determined. Results. As soon as the injection has been given, the TSW in animals of both groups hasn`t differed significantly. The TSW has significantly increased in both of the groups, and the parameters of indicators in the experimental group have significantly raised in 1 h after the injection. In 3, 6, and 12 hours, the TSW in both groups has been decreasing. The parameters of indicators in the experimental group of animals have been significantly higher than in the control one all the time during the study. The indicators have barely differed from the initial ones in the control group 12 hours later, whereas in the experimental one they have been significantly higher. Histological studies have shown that the structure of stomach tissues in both groups hasn`t varied. The SG injection has not caused any negative effects on the tissues of the stomach wall. The thickness of the submucosa hasn`t been much modified right after the injection. The thickness (26.95±5.34 microns) has increased in the experimental group 12 hours later than in the control one (15.45±4.38 microns, p<0.01). Most of the vessels of the experimental group have remained compressed 12 hours later, whereas the diameter of the vessels of the control group has been growing. Conclusions. 1. The TSW hasn`t differed right after the injection (a mixture of 0.9 % NaCl and epinephrine solution and a mixture of SG and epinephrine solution) into the stomach wall. 2. 1 h later after the injection, the TSW has increased and its parameters after injection of a mixture with SG have been significantly higher. 3. In 3,6,12 h and later on, the TSW has been gradually reducing and its parameters after injection of a mixture with SG have been significantly higher each time. The thickness of the submucosa and the degree of compression of the vessels have also been considerably higher. 4. No negative changes in the structure of stomach tissues after injection of the mixture with SG have been detected. This allows it to be used for performing endoscopic hemostasis by injection therapy in clinical conditions.

Victims Of Bullying

In general, bullying has negative effects on victims, including increased anxiety, decreased self-esteem, self-distrust and depression. These things will affect to the concentration of student learning which ultimately leads to decrease learning achievement and more risk of suicide in adolescents. Therefore, developing the resilience of youth victims of bullying is needed to provide therapeutic coping to avoid these adverse effects. This study aims to determine the effectiveness of Spiritual-based psychoeducation therapy on the Level of Resilience of Youth Victims of Bullying. This is quasy experimental pre-post test research with total sampling. The sample is high school students who have experienced bullying in the past month, are physically healthy, and have no disabilities. The sample of this study was 50 and has been divided into two groups, namely the intervention group and the control group. This research used questionnaire’s ability of resilience in adolescents by Gail M wagnild and Heather M. Young. The results showed a significant effect of psychoeducation spiritual therapy on the level of adolescent resilience (p-value is 0.000 by Kolmogorov Smirnov). Schools need to consider this therapy as a choice to be applied to student victims of bullying.

Abstract Background Disease monitoring is an important element of self-management of several chronic diseases. Pain monitoring has become very easily available, but the role in musculoskeletal pain conditions is not clear. Awareness of pain might be helpful for people to understand pain, but focusing on pain may on the contrary negatively affect pain experience and behaviours. The objective of this study was to investigate the potential impact of pain monitoring on low back pain (LBP), specifically to determine if pain intensity, activity limitation and pain control, differed between patients with weekly pain monitoring over 12 months and patients with follow-ups at 2 weeks, 3 months and 12 months. Methods This was a non-randomised controlled study embedded in a cohort study with data collection November 1st 2016 to December 21st 2018. Adults seeking care for LBP were enrolled at the first visit to a chiropractor and followed with surveys after 2 weeks, 3 months and 12 months. Those enrolled first, n = 1,623, furthermore received weekly SMS-questions about pain frequency and pain intensity, whereas those enrolled next was the control group, n = 1,269 followed only by surveys. Outcomes at 12-months were compared, adjusting for group differences on baseline parameters. Results LBP intensity (0–10) was slightly lower at 12-months follow-up in the SMS group than the control group (adjusted beta − 0.40 (95% CI: − 0.62; − 0.19)). No relevant between-group differences were observed for activity limitation (0–100) (1.51 (95% CI: − 0.83; 3.85)) or ability to control pain (0–10) (− 0.08 (95% CI − 0.31; 0.15)). Conclusions Frequent pain monitoring did not demonstrate any negative effects of weekly pain monitoring, and it was perhaps even helpful. The role of self-monitoring as part of self-managing LBP should be explored further including optimal frequencies, formats, and methods for feedback. Trial registration The study was not registered as a clinical trial.
