Many factors present in eggs’ transportation from incubator to growing confinements can damage their integrity and, consequently, the results of the incubation. This study aimed to evaluate whether the intensity and duration of exposures of hatching eggs to mechanical vibrations were capable of affecting the hatch and the quality of broiler chicks. Four treatments, determined by two intensities of vibrations and two durations of exposures were evaluated and compared with a control group in a randomised design in blocks with four repetitions. The vibrations were applied by a mechanical shaker before incubation. Then the eggs were incubated and as the following responses were evaluated: hatchability, the type of embryonic mortality, the quality of the birds and the total of losses. The analyses were carried out by a binomial regression model, with application of the Wald test at 5% significance level. The results showed that the exposure of eggs to mechanical vibrations harmfully affects the hatchability and reduces the ratio (percentage) of high quality chicks. Highest vibration level together with longer duration of exposure resulted in worst hatchability and losses. It is argued that the mechanical vibrations are potentially damaging and should be regarded as an important factor in the management of hatching eggs.

Abstract Background Cancer-related insomnia (CRI) is one of the most prevalent complaints among cancer survivors and severely impairs patients’ quality of life. As a popular non-pharmacological alternative treatment, acupuncture provides a good clinical curative effect on insomnia. The aim of this trial is to evaluate efficacy and safety of electro-acupuncture on insomnia in patients with lung cancer. Method This is a protocol for a multicenter randomized single-blinded sham-controlled trial. We will randomly assign 252 eligible patients with lung cancer-related insomnia into two groups at a ratio of 1:1, the treatment group (EA) and the control group (sham EA). All treatment will be given 3 times per week for 8 weeks, and a 12-week follow-up will be conducted. The primary outcome will be measured by the Pittsburgh Sleep Quality Index (PSQI). The secondary outcomes will include sleep parameters recorded from the actigraphy, scores from Quality of Life Questionnaire Core-30 (QLQ-C30), and Patient Health Questionnaire-9 (PHQ-9). All adverse effects during the trial will be assessed by the Treatment Emergent Symptom Scale (TESS). All analyses will be based on ITT principle and performed with the statistical software SPSS (version 24.0) by t test, rank-sum test, chi-square, and so on. A two-sided significance level will be set at 5%. Discussion This large-sample trial protocol will evaluate the efficacy of electro-acupuncture on insomnia in patients with lung cancer. This protocol, if proven to be effective, will contribute to filling the gap in treatment options in the CRI field and provide a promising intervention for insomnia in lung cancer survivors.

An experiment was conducted with 60 day old Cobb-500 broiler chicks for a period of 28 days with the aims of investigating the effects of different level of garlic powder on growth performance, carcass characteristics and meat quality of broilers to produce safe broiler meat. The experimental broiler chicks were divided randomly into four different groups with three replications having 5 chicks in each. Maize-soybean based diet was used as basal diet for group 1. Basal diet was supplemented with 1%, 2% and 3% garlic powder on fresh basis for group 2, 3, and 4 respectively. The broiler of groups 2, 3, and 4 were showed significantly (p>0.05) higher body weight than control group at 4 weeks of age. Feed conversion ratio of group 2, 3, and 4 were significantly (p>0.05) lower than group 1. Group 2 was given significantly lower fat percentage than other groups. Group 3 and 4 showed more or less similar fat content but lower than control groups. Thus, it may be concluded that garlic powder may be used in chicken diet.Bang. J. Anim. Sci. 2016. 45 (2): 79-83

Abstract Background: Multiple sclerosis (MS)is the most common neurological disease that causes disability in the nervous system which reduces the quality of life(QoL). Studies have shown positive effects of therapeutic exercise with supplementation on motor- and cognitive functionandfatigue as well as on QoLin persons with MS. The purpose of this study was to the effect of home-based aerobic training (AT) and vitamin D(Vit D) supplementation on fatigue and QoL in patients with MS during the covid-19 outbreak. Methods: We recruited 40 females (20 - 40 years) with MS(EDSS: 3-5). Then, using simple randomization, the subjects were assigned to four groups including aerobic training (AT; n=9; 50%-75%, 20-40 min/day, 3 days/wk aerobic training), vitamin D supplementation (Vit D; n=9; 50,000 IU one day/week), aerobic training plus vitamin D supplementation (AT + Vit D; n=10), and sedentary control (C; n=10 placebo). The data were analyzed using paired t-test and one-way analysis of variance and Tukey’s post hoc test with SPSS21 at a significance level of P < 0.05.Results: After eight weeks of intervention, fatigue grade markedly reduced in the AT + Vit D, AT, and Vit D groups); However, fatigue increased in the control group. QoLincreased significantly in AT+Vit D, AT, and Vit D compared to C. Also, the results show that the AT+Vit D had significantly higherQoL compared to AT and Vit D. Conclusion:These findings suggest that therapeutic AT and VitD supplementation is very effective in reducing fatigue and consequently improves the QoLin female MS patients.

The study examined the effect of dietary antioxidant supplementation on the performance and meat quality of broiler chickens. Namely, 300 one-day-old Arbor Acres broiler chicks were fed a starter diet from 1 to 4 weeks and a finisher diet for the last 4 weeks. Birds were randomly assigned to treatments based on antioxidant supplementation in drinking water at 0.02% butylated hydroxyanisole (BHA), ordinary water (OW), 0.02% sweet orange peel extract (SOPE), 0.02% shaddock peel extract (SHPE) and 0.02% lemon peel extract (LMPE) per litre of water in a completely randomized design experiment. Feed intake and body weight gain were recorded on a weekly basis. Three birds were selected in each treatment and slaughtered for meat quality determination. BHA and LMPE treatments had the best weight gain and feed conversion efficiency at the significance level (p<0.05). There were significant differences (p<0.05) in the shear force (force peak and yield) in the dietary antioxidants fed to the birds. Sensory parameters (taste, aroma and overall acceptability) show significant differences (p<0.05) amongst the treatments. However, there were no significant differences (p>0.05) in appearance and texture perception amongst treatments. Finally, significant differences (p<0.05) in the lightness (L*) and redness (a*) of the meat samples were observed amongst the treatments. There were no significant differences (p>0.05) in the yellowness (b*) amongst the treatments. It can be concluded that broiler birds fed SOPE, SHPE and LMPE treatments performed better and that these treatments enhanced the meat quality of the birds when compared to BHA and OW treatments.

The results of studies on the effect of synthetic tryptophan supplements to goose feed during the reproductive period on the incubation qualities of eggs, the level of total protein, albumin and α-, β- and γ-globulins in the blood of embryos and newborn goslings are presented. The study was conducted on four groups of geese-analogues of the Obroshyn gray breed group during the 3-month period (January ‒ March). The control group did not receive synthetic tryptophan supplements. The level of this amino acid in this group of geese in accordance with current regulations in Ukraine was 0.16 g per 100 g of feed. To the diet of birds 2, 3 and 4 experimental groups were additionally administered, respectively, 0.04; 0.09 and 0.14 g of synthetic tryptophan per 100 g of feed. As a result of research it was found that increasing the level of tryptophan from 0.16 g to 0.30 g per 100 g of feed due to its synthetic analogue in the diet of geese during egg-laying significantly improves the incubation quality of eggs and has a positive effect on protein levels. daily embryos and 5-day-old goslings. It is shown that the most pronounced effect on improving the quality of hatching eggs and optimizing the effect on the level of protein in the blood of embryos and goslings reveals the content of tryptophan in feed during intensive laying of geese in the amount of 0.25 g per 100 g of feed. Studies have shown that the quality of hatching eggs and the content of total protein, albumin and α-, β- and γ-globulins in the blood of embryos and newborn goslings has a pronounced positive effect on the level of tryptophan in the diet of geese during intensive laying. In particular, increasing the amount of this essential amino acid in goose feed during the reproductive period from 0.16 to 0.30 g due to its synthetic analogue improves such incubation qualities of eggs as: egg-laying, weight, length, width, egg shape index, strength and thickness eggshells, and increases in the serum of 25-day-old embryos and 5-day-old goslings contents of total protein, albumin and α-, β- and γ-globulins (P < 0.05). It is shown that the most pronounced positive effect on the optimization of protein ingredients in the serum of both embryos and goslings was found for the content of tryptophan in the feed of geese of the parent flock in the amount of 0.25 g per 100 g of feed. The results show that increasing the level of such essential amino acids as tryptophan in goose feed during intensive egg-laying from 0.16 to 0.25 g per 100 g of feed activates the synthesis of egg components in the ovary of birds, improves their quality and has a stimulating effect on the biosynthesis in hepatocytes of embryos and newborn goslings of total protein, its albumin, α-, β-globulin fractions and immune γ-globulins.

Introduction: Amongst other problems, dialysis patients also present mental and psychological problems. Objectives: In this study, we investigated the effect of mindfulness-based cognitive therapy (MBCT) on quality of life and self-efficacy in hemodialysis patients. Patients and Methods: In a descriptive study, 50 hemodialysis patients undergoing dialysis in Hajar hospital were randomly selected and divided into two groups of experimental and control. The experimental group attended 2 to 2.5 hours treatment sessions according to the MBCT program. Before the intervention and two months after, the outcomes of the study, regarded as, quality of life and self-efficacy were evaluated using the 36-Item Short Form Health Survey (SF-36) and Sherer et al’s General Self-efficacy Scale, respectively. Data were analyzed using descriptive statistics, independent t test, paired t test, and Wilcoxon test in the Stata software. Results: The results indicated that 2 months after intervention, a decrease of 2.05 points in mean score for quality of life in the control group and an increase of 10.30 points in the intervention group at P<0.01 significance level was detected. Furthermore, mean self-efficacy score increased by 0.95 in control group and 5.2 points in the intervention group at P<0.01 significance level. While, the mean scores for quality of life and self-efficacy increased after intervention, the difference in the mean scores between the two groups was not statistically significant after intervention (P>0.05). Conclusion: The results of this study showed that the MBCT program resulted in an increase in the mean scores for quality of life and self-efficacy in hemodialysis patients.

ABSTRACT Purpose: to analyze the impact of dysarthria on the quality of life in patients with amyotrophic lateral sclerosis. Methods: the study consisted of 32 subjects, divided into two groups (control group and study group) who underwent an initial interview for background information, followed by an evaluation based on the Dysarthria Assessment Protocol and completion of quality of life questionnaire "Living with Dysarthria - (LwD)". Exploratory data analysis was collected through mean, median, SD, minimum and maximum measures. A comparison was performed between the studied groups and a correlation was carried out between scores. The significance level adopted was 5%. Results: according to the findings, all sub-items analyzed by the dysarthria assessment protocol were statically significant (p <0.001) when comparing the groups. Regarding quality of life, a moderate positive correlation (p = 0.0008; Spearman's coefficient = 0.75202) was observed between the total score of the two protocols used, indicating that the higher the degree of dysarthria, the worse the Quality of Life (QOL) of the subject, according to the parameters evaluated. Conclusion: dysarthria affects all speech parameters herein assessed, in varying degrees, negatively impacting communication and quality of life.

The present study aimed to investigate the effects of dietary supplementation with powdered peanut skin (PS) as natural antioxidant and growth promoter on growth performance, carcass characteristics, serum metabolites and meat quality of Cobb broiler chickens. A total of 240 unsexed Cobb 500 1-week-old broiler chicks were randomly assigned to four treatment groups with six replicates. The dietary treatments consisted of the basal diet as control and PS groups (1.0, 2.0, and 3.0 PS g/kg). Results showed that the highest values (P < 0.01) of live bodyweight and bodyweight gain were observed in the control group at 3 weeks of age and during the period of 1–3 weeks of age, respectively compared with all levels of PS. During 1–3 weeks of age, feed intake per day chicks fed the diet containing PS levels decreased numerically (P > 0.01) with increased levels of PS compared with the control. Supplementing 1.0 or 3.0 g/kg of PS insignificantly enhanced feed conversion ratio at 1–6 weeks of age. Dietary treatments significantly depressed giblets (P = 0.002), thigh (P = 0.0.027) and abdominal fat percentages (P > 0.0.1), however, increased (P = 0.004) breast percentage of broiler chicks at 6 weeks of age. The lowest value of serum creatinine and urea achieved by chicks fed diet contained 3.0 PS g/kg diet. Also, high density lipoprotein cholesterol in addition to triglycerides were significantly (P < 0.05 and P < 0.01) decreased with increasing level of PS supplementation. It can be concluded that PS as a phytogenic additive could be used as a supplementation to broiler diets to lower abdominal fat in carcass and cholesterol, creatinin and urea in blood. Sensory characteristics were not affected except that appearance was improved. Water-holding capacity was also improved.
