The Impact

Abstract The aim of the study was to determine the impact of intramuscular tagging with passive integrated transponders (PIT tags) on the basic condition and hematological and biochemical indexes of the blood plasma of juvenile European perch (initial body weight of approximately 80 g). Throughout the observation period, i.e., for 42 days following PIT implantation, the procedure was not noted to have had a negative impact on fish growth, condition, or feed conversion ratio. The blood plasma biochemical indicators analyzed did not differ statistically significantly between the fish tagged with PIT and the untagged control group. No significant impact from this procedure was noted in the hematological indexes tested. Only with regard to the mean corpuscular hemoglobin (MCH) parameter was the value significantly lower in the fish tagged with PIT than in the control group (P ≤ 0.05). The difference determined was 1.40 pg (28.78 vs. 30.18). The MCH level in the fish tagged with PIT most probably was within the norm for this species. High tag retention (100%) and the lack of any significant impact on condition or hematological and biochemical indexes (with the exception of MCH) permits recommending this tagging method for use in juvenile perch.

Abstract The aim of the study was to determine the impact the surgical implantation of acoustic transmitters (AT; implantation incisions were sutured with tissue adhesive) had on the condition and health of pikeperch, Sander lucioperca (L.), (initial body weight of approximately 600 g). After tagging, the fish were held for 42 days in recirculating aquaculture systems. During this period, no negative effects were observed stemming from the implantation of AT on fish growth, condition, survival, or foraging effectiveness. The procedure also did not have a negative impact on hematological indicators. Among the 13 biochemical blood plasma indicators analyzed, only glucose level in the fish tagged with AT was significantly lower than that in the control group (P≤0.05). The rate of wound healing and the condition of the implantation incisions raised no concerns. Three weeks following the AT implantation procedure the incisions were closed and no infection was noted. Short-term AT retention (42 days) was 83.3%, and the fish shed the tags in the first two weeks following implantation.

The Impact

A modern school deals with a generation of students who were born and grown up in a digital environment and require other teaching methods. Changes in the technological and social conditions of modern society need new professional skills, which are often called “21st century skills”. These skills should be devel-oped starting from the primary school, as they are psychological and behavioural, rather than practical. Game-based learning and gamification are effective means of such skills development. The use of video games in teaching practice is studied multifaceted, along with formats and requirements of educational game, methods for effectiveness assessment, and the effect of games on students. The controver-sial nature of game-based learning effect on students require deeper research, as the increase in motivation and learning efficiency cannot be disputed, as well as the negative impact of a long gaming on cognitive abilities, emotional state and social skills of students. The study tested both an increase in the motivation and attraction of school students for the learning process, and the impact on the prac-tical results of information assimilation. There was conducted a survey on the re-sults of the application of game training to determine the motivation and attraction of students. Likewise, we counted time, spent by the study and control group, for mastering the main educational material and the post-class study of game content and the educational material it presents. A comparative test was conducted on the results of educational material comprehension to determine the effectiveness of the methodology in mastering knowledge. The group, with game-based learning and gamification applied, showed an increase in motivation and attraction to learning, students paid additional efforts for assimilating the material studied, and also showed significantly higher learning outcomes compared to the control group.

Yucca Schidigera

Ammonia is a critical hazardous nitrogen metabolic product in aquaculture. Despite trials for its control, ammonia intoxication remains one of the most critical issues to overcome. In this study, we explored the modulatory effect and potential mechanism by which Yucca schidigera extract (YSE) can ameliorate ammonia intoxication-induced adverse effects on tilapia health and metabolism. A total number of 120 Nile tilapia were evenly assigned into four groups with three replicates each. The first group served as normal control group; the second group was exposed to ammonia alone from the beginning of the experiment and for four weeks. The third group was supplied with YSE in water at a dose of 8 mg/L and exposed to ammonia. The fourth group was supplied with YSE only in water at a dose of 8 mg/L. YSE supplementation succeeded in improving water quality by reducing pH and ammonia levels. Moreover, YSE supplementation markedly alleviated chronic ammonia-induced adverse impacts on fish growth by increasing the final body weight (FBW), specific growth rate (SGR), feed intake and protein efficiency ratio (PER) while reducing the feed conversion ratio (FCR) via improvements in food intake, elevation of hepatic insulin-like growth factor (ILGF-1) and suppression of myostatin (MSTN) expression levels with the restoration of lipid reserves and the activation of lipogenic potential in adipose tissue as demonstrated by changes in the circulating metabolite levels. In addition, the levels of hepato-renal injury biomarkers were restored, hepatic lipid peroxidation was inhibited and the levels of hepatic antioxidant biomarkers were enhanced. Therefore, the current study suggests that YSE supplementation exerted an ameliorative role against chronic ammonia-induced oxidative stress and toxic effects due to its free radical-scavenging potential, potent antioxidant activities and anti-inflammatory effects.

Background: Italy was one of the first affected countries by coronavirus disease 2019 (COVID-19) pandemic. Public health measures like quarantine or national lockdown were adopted, with negative psychological and clinical effects on patients with chronic diseases. To investigate the impact of lockdown on patients with multiple sclerosis (MS), we developed a 36 items self-report questionnaire. Methods: Questionnaires were emailed to 120 patients with MS and 100 with chronic migraine (CM) as a control group, matched for age, sex, and education. The questionnaire was divided into five domains, evaluating concerns about 1) MS and therapy during COVID-19 pandemic, 2) personal and family caregiving, 3) working activities, 4) general and disease-related emotions during the lockdown, 5) future expectations concerning health status, social life, and working activity. Results: patients with MS had higher scores than those with CM in domains 4 and 5, investigating respectively general and disease-related emotions and future expectations (p= 0.05 and 0.02 respectively). About half of the patients with MS expressed some concern about the need to continue their therapy during the pandemic compared to people with CM (p= 0.0002). Conclusions: Covid-19 pandemic had a more negative impact on psychological status of patients with MS compared with those with CM

IntroductionIntervention with informal caregivers (IC) of psychiatric patients is internationally recognized as relevant and a priority. However, the existing responses in this area are still insufficient, especially regarding caregivers of individuals with mood disorders (MD). Mindfulness and compassion focused therapy have proven to be an effective approach in stress reduction and in improving emotional and social well-being of caregivers of patients with other conditions. However, no studies testing these new approaches in IC of patients with MD have been carried out. The objective of this work is to present a research project that aims to develop, implement and empirically test the effectiveness of an innovative group program to help informal caregivers of individuals with mood disorders to cope with the negative impact of the disease and reduce caregiver burdens.MethodsThe design of this experimental study to test the program's efficacy is a non-randomised controlled trial (nrct) with 12 months follow-up, with a mixed assessment methodology (quantitative and qualitative analysis). A sample of 60 informal caregivers of individuals with chronic MD will be constituted (n = 30 Control group; n= 30 Experimental group).ResultsWe expect the program to promote significant changes in participants in terms of several emotional variables (eg: burden, stress, resilience, compassion and quality of life).ConclusionsFurther efforts to continue studying the impact of interventions in caregivers should be carried out, as a way to improve the quality of life of caregivers and their ability to provide informal care to MD patients.Disclosure of interestThe authors have not supplied their declaration of competing interest.

This paper evaluates the impact of long-term supplementation of different forms of zinc (Zn) and selenium (Se) on the content of these substances in the blood and hair of goats. Two analogous supplementation experiments were performed. 37 goats divided into four groups were used in the first trial with the Zn supplementation. Group A (n = 10) was a control group (with no Zn administered). A further three groups (B, C, D) were supplemented with Zn in various forms. Group B (n = 9) with zinc oxide, Group C (n = 9) with zinc lactate and Group D (n = 9) with zinc chelate. The second trial with Se supplementation was carried out on 20 goats divided into four groups. Group E (n = 5) was a control group. The other three groups were administered Se. Group F (n = 5) was supplied with a selenium lactate-protein complex, Group G (n = 5) with sodium selenite and Group H (n = 5) with selenium yeast. Three months later blood and hair samples were taken from all animals and Zn and Se concentrations were determined in whole blood, plasma, and hair. Glutathione peroxidase (GSH-Px) activity was determined in the Se supplementation trial group. At the end of the trial the Zn concentrations in plasma and whole blood were without major differences between the groups. The plasma concentration of Zn did not increase from the initial value at the start of the trial. In hair the average concentration of Zn was 95.2&ndash;100.0 mg/kg<br />in all groups. No conclusive relation was confirmed between the values of Zn in hair and its concentration in blood. The Se concentration in whole blood (&micro;g/l) at the end of trial in supplemented groups (F &ndash; 188.8 &plusmn; 24.6; G &ndash; 197.2 &plusmn; 10.9; H &ndash; 190.1 &plusmn; 26.3) was significantly higher (P &lt; 0.01) than in the control group (E &ndash; 103.1 &plusmn; 23.5). Similarly, the activity of GSH-Px (&micro;kat/l) was significantly higher in all supplemented groups (F &ndash; 872.3 &plusmn; 94.8; G &ndash; 659.5 &plusmn; 176.4; H &ndash; 839.8 &plusmn; 150.8) than in the control group (E &ndash; 379.1 &plusmn; 63.5). Se content in hair (&micro;g/kg) was higher also in all trial groups (F &ndash; 242.3 &plusmn; 41.5; G &ndash; 200.5 &plusmn; 46.9; H &ndash; 270.0 &plusmn; 106.8) than in the control group (E &ndash; 174.7 &plusmn; 38.0). However, it was significantly (P &lt; 0.05) higher only in Group F. A conclusive correlation was identified between the Se concentration in whole blood and its content in hair (r = 0.54; P &lt; 0.05; n = 20). Based on the results it can be concluded that none of the supplemented forms of Zn increased its concentration in blood, plasma and hair. On the other hand, the administration of Se led to an increase in the Se concentration in blood, increased the activity of GSH-Px in whole blood and the Se content in hair. Based on the proven correlation and regression relation between the Se concentration in blood and its content in hair, hair can be considered as a suitable material for the diagnosis of long-term Se status in goats. Goats with sufficient Se status are those that have more than 160 &micro;g/kg of Se in hair dry weight.

Abstract The aim of the study was to determine the impact of diet and sex on the hematological and blood plasma biochemical profiles and the liver histology of pikeperch, Sander lucioperca (L.) reared in recirculating aquaculture systems (RAS) (initial mean body weight (BW) 1.35 kg). The proximate composition of the two commercial feeds used were (protein/lipid/nitrogen-free extracts) (P/L/NFE)) P505/L118/NFE294 g kg−1 (group I) and P471/L141/NFE290 g kg−1 (group II). Neither diet nor sex had a significant impact on final fish body weight (≈ 2.0 kg). Sex was noted to significantly impact glucose content (Glu – higher in males) and cholesterol (Chol – higher in females) in the blood plasma. Diet was confirmed to have a significant impact on levels of hematocrit (Ht), hemoglobin (Hb), and mean corpuscular hemoglobin (MCH), and the values of these indicators were higher in group I. Sex had a significant impact on Ht, Hb, MCH, and mean corpuscular hemoglobin concentration (MCHC), with higher values in male pikeperch. Diet and sex had significant impacts on the values of the pikeperch hepatosomatic index (HSI), hepatocyte size and that of their nuclei, and the values of the nucleocytoplasmic index (NCI).

Introduction: Psoriasis is a chronic skin disease characterized by scaly patches affecting approximately 2-5% of the population. The disease has a negative impact on quality of life and, therefore, psoriatic patients often develop depression. Our work deals with quality of life and depression in psoriasis sufferrers and strives to determine the correlation between their quality of life and depression. Methods: The research took place in the University Hospital Olomouc in 2017 and used questionnaires WHOQOL-BREF and BDI-II. 50 patients with psoriasis were chosen randomly. To process the data we used Mann-Whitney test (the level of significance = 5%) and Spearman´s correlation coefficient (the level of significance = 1%). Results: The results proved that psoriasis has a significant impact on quality of life. The scores for the overall life quality as well as for individual domains were significantly lower in psoriatic patients than in the control group (p&lt;0.001). The degree of depression in patients with psoriasis showed statistically significant correlation in all domains of the quality of life. We proved negative correlation in the overall quality of life (rs =- 0.691**), physical condition (rs =-0.499**), social relations (rs =-0.546**), overall health (rs =-0.396**), and environment (rs =-0.386**). Conclusion: With regard to the ascertained negative correlation between psoriasis and depression and lower quality of life of the sufferers compared to the healthy population, it is essential for healthcare professionals to pay attention not only to somatic manifestations of the disease but also to the patients´ mental health.

Systematic overload, which is a training characteristic of powerlifters with visual impairments of high qualification has a negative impact on the functioning of body systems and the course of the underlying and comorbidities. This determines the relevance of the scientific substantiation of training programs for athletes with visual impairments as the most important component of ensuring the achievement of sports results in powerlifting. This study aimed to experimentally substantiate the effectiveness of the impact of various training programs on physical fitness and athletic performance of powerlifters with visual impairments of high qualification. To solve the goal we used methods of analysis of scientific and methodological literature, pedagogical observation, pedagogical experiment and methods of mathematical statistics. The study involved 16 visually impaired athletes who were members of the national powerlifting team. The pedagogical experiment was based on testing the effectiveness of two training programs, which differed in the parameters of the load components in the annual training and macrocycle periods. After the pedagogical experiment, the experimental group showed reliable indicators of growth on all tests and improvement of sports results, and athletes of the control group increased physical fitness in three tests out of five and sports results are available only in squat and bench press. In both groups, the highest growth rates in the level of development of physical qualities were found in tests aimed at determining the level of development of strength and flexibility. Comparing the results of the introduction of various training programs in the training process of powerlifters with visual impairments, we can conclude that the performance of the experimental group is much higher than among the powerlifters of the control group.

Introduction: One of the consequences of aging is the prevalence of chronic and age-related diseases, such as dementia. Caring for patients with dementia has a negative impact on the caregiver's well-being. This study aimed to examine the impact of cyberspace-based education on the well-being of caregivers of demented elderly people. Methods: This experimental study was done on a sample of 86 caregivers of elderly with dementia in 2018. The study sample was selected from memory clinic of Taleghani Hospital and randomly assigned into groups (intervention n = 43, control n = 43 groups). The well-being was measured using the World Health Organization - Five Well-Being Index (WHO-5), before and two months after the intervention. Cyberspace-based educational intervention was conducted for one month. The SPSS software version 23 was employed in data analysis. Results: The mean age of the caregivers in the intervention and control groups were (M = 51.95, SD = 10.90) and (M = 51.36, SD = 15.12) respectively. No significant difference was found between two groups in terms of age, gender and level of education. The results of analysis showed that while the well-being of the intervention group was significantly increased (t (38) = -11.38, P<0.001) the well-being in the control group was significantly reduced ( t(36) =4.71 , P<0.001). Conclusion: The findings showed that cyberspace-based education can improve the well-being of caregivers of the elderly with dementia.
