The Effect of Dietary Methionine Levels on the Performance Parameters of Arctic Foxes (Vulpes Lagopus)The objective of this study was to determine the effect of dietary inclusion levels of methionine and cystine on the performance traits and health status of Arctic foxes. The experimental material comprised 60 blue Arctic foxes of the Finnish type. Control group (C) animals were fed diets (CA and CB) with standard concentrations of methionine and cystine. In experimental groups E1 and E2, methionine content was increased by approximately 2 g per 100 g total protein, relative to the recommended intake. Diets for group E1 were supplemented with liquid methionine (E1A and E1B), and diets for group E2 were supplemented with crystalline methionine (E2A and E2B). Diets A were offered during the growing period, and diets B were administered during the furring period. During the growing period, methionine+cystine levels in diets E1 and E2 were 4.19+0.59 g and 4.22+0.53 g per 100 g total protein, respectively. During the furring period, methionine+cystine levels were 4.83+0.68 g in diets E1 and 4.91+0.61 g in diets E2. The body weights of Arctic foxes were determined, their body conformation was evaluated, and the duration of the rearing period was calculated. Blood samples for morphological and biochemical analyses were collected from animals aged 24 weeks, selected randomly from each group. After slaughter, pelt length and fur quality were determined in accordance with the International Trading System. The results of this study indicate that diets for Arctic foxes should be supplemented with methionine. The experimental diets contributed to improving the performance traits of foxes, in particular fur quality, and they had no adverse influence on the health status of animals. It may be concluded that farm-raised Arctic foxes of the Finnish type show an increased demand for methionine.

ABSTRACTThis work presents an alternative methodology for monitoring flight performance during airline operations using the available inboard instrumentation system. This method tries to reduce the disadvantages of the traditional specific range monitoring technique where instrumentation noise and cruise stabilisation conditions affect the quality of the performance monitoring results. The proposed method consists of using an unscented Kalman filter for aircraft performance identification using Newton’s flight dynamic equations in the body X, Y and Z axis. The use of the filtering technique reduces the effect of instrumentation and process noise, enhancing the reliability of the performance results. Besides the better quality of the monitoring process, using the proposed technique, additional results that are not possible to predict with the specific range method are identified during the filtering process. An example of these possible filtered results that show the advantages of this proposed methodology are the aircraft fuel flow offsets, as predicted in the specific range method, but also other important aircraft performance parameters as the aircraft lift and drag coefficients (CL and CD), sideslip angle (β) and wind speeds, giving the operator a deeper understanding of its aircraft operational status and the possibility to link the operational monitoring results to aircraft maintenance scheduling. This work brings a cruise stabilisation example where the selected performance monitoring parameters such as fuel flow factors, lift and drag bias, winds and sideslip angle are identified using only the inboard instrumentation such as the GPS/inertial sensors, a calibrated anemometric system and the angle-of-attack vanes relating each flight condition to a specific aircraft performance monitoring result. The results show that the proposed method captures the performance parameters by the use of the Kalman filter without the need of a strict stabilisation phase as it is recommended in the traditional specific range method, giving operators better flexibility when analysing and monitoring fleet performance.

Abstract Objectives. Early detection of malignant tumour is a prerequisite for a successful treatment. Here we investigate if thymidine kinase 1 is more sensitive than imaging technology to discover small invisible malignant tumours.Material and Methods. The cellular concentration of TK1 was determined by a novel automatic chemiluminescence analyzer of magnetic particle immune sandwich minimum. The primary and secondary antibodies linked to the magnetic beads were chicken anti-human thymidine kinase 1 IgY-polyclonal antibodies (IgY pAb). The minimum number of cells able to be detected by the novel detection technology using an automatic chemiluminescence analyzer were determined based on the cellar TK1 concentration of low and high TK1 cell lines of known cell count.Results. The TK1 concentration of malignant cell was found to be 0.021 pg/cell. Assuming 200 pg of total protein/cell, TK1 corresponds to 0.01 % of the total protein/cell. The concentration of TK1 in human blood serum of malignant patients is in the range of 2-10 pmol/l (pM), corresponding to about 50 x106 growing cells in the body that release TK1 into 5 litre blood. The limit visibility by imaging of a tumour is about 1 mm in diameter, corresponding to about 109cells of a cell diameter of 1µm. Conclusion. TK1 is more sensitive than imaging.

Objective: Many plants are consumed as food by humans for growth and survival, but a large number of these plants have not been tested for toxicity potential. Repeated consumption of such plants could lead to accumulation of toxic chemicals in the body and cause health-related problems. Irvingia wombolu kernel is widely consumed by many ethnic groups in Nigeria and some other African countries. The toxicity potentials of Irvingia wombolu kernel extract (IWKE) on the kidney and liver of rats was evaluated in this study. Methods: Three groups of Wistar rats were fed orally with IWKE (50, 100, and 200 mg/kg b.w) daily for 28 days. The fourth group which is the control was treated with distilled water (10 ml/kg b.w) for the same period.  The rats were sacrificed on the 29th day, and blood samples, kidney and liver were harvested for analyses. Serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), total protein, albumin, bilirubin, creatinine, and urea were determined. Kidney and liver sections were examined for histopathological changes. Data were subjected to Student’s t-test for statistical analysis. Results: Serum levels of creatinine and urea were not significantly altered in the IWKE-treated rats compared with the control. At 200 mg/kg b.w, the extract significantly increased (p<0.05) serum levels of ALT, AST, total bilirubin, total protein, and albumin compared with the control. Significant distortions were observed in the liver sections of rats treated with 200 mg/kg b.w IWKE compared with control, but the structure of the kidney section of IWKE-treated rats was not significantly different from the control. Conclusion: The results showed that repeated ingestion of Irvingia wombolu kernel at a dose of 200 mg/kg b.w for 28 days induced liver damage, but does not significantly affect renal function.                       Peer Review History: Received: 9 September 2021; Revised: 12 October; Accepted: 27 October, Available online: 15 November 2021 Academic Editor:  Dr. Ali Abdullah Al-yahawi, Al-Razi university, Department of Pharmacy, Yemen, [email protected] UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system.

The aim of the study is to increase the productive qualities of broiler chickens by including ultrafine silicon oxide into main diet. During the experiment, the biological effect of ultrafine silicon oxide on broiler chickens was estab-lished. Use of ultrafine SiO2 particles for poultry feeding contributed to an increase in the number of red blood cells and content of total protein and albumins. By the end of the experiment, the number of red blood cells in birds in-creased by 17.43% (P≤0.001) – in the blood of birds of the first experimental group, 16.51% (P≤0.01) – the second one, 20.80% (P≤0.001) – the third experimental and 21.71% (P≤0.001) – the fourth experimental group, compared with the indicator of the control group. The amount of total protein in blood serum of chickens of the first and the second experimental groups increased by 1.36-1.39 %, in the third and fourth ones there was a significant (P≤0.05) increase by 5.45 and 3.05%, respectively. The blood glucose content of chickens in the experimental groups is higher by 8.04-23.65% compared to this indicator with ones in the control group. During the experiment feed con-sumption per 1 kg gain of live weight decreased: in the first experimental group by 3.00 % in the second by – 0.50 %, the third – 6.00 % the fourth– by 4.50 %, compared to this with the control group. The chicken’s vibrancy of the first the experimental group was higher by 4.77 %, the second – by 6.20 %, the third – by 19.25 % and the fourth– by 11.59% than in the control one. Consequently, when converting the feed energy into the body energy of a broiler chicken, the energy conversion coefficient of the experimental group of poultry is higher than that of the control one by 7.16-21.76 %. Thus, the most optimal dose for further research was determined.

Abstract The potential for preventive and therapeutic applications of H2 have now been confirmed in various disease. However, the effects of H2 on health status have not been fully elucidated. Our previous study reported changes in the body weight and 13 serum biochemical parameters during the six-month hydrogen intervention. To obtain a more comprehensive understanding of the effects of long-term hydrogen consumption, the plasma metabolome and gut microbiota were investigated in this study. Compared with the control group, 14 and 10 differential metabolites (DMs) were identified in hydrogen-rich water (HRW) and hydrogen inhalation (HI) group, respectively. Pathway enrichment analysis showed that HRW intake mainly affected starch and sucrose metabolism, and DMs in HI group were mainly enriched in arginine biosynthesis. 16S rRNA gene sequencing showed that HRW intake induced significant changes in the structure of gut microbiota, while no marked bacterial community differences was observed in HI group. HRW intake mainly induced significant increase in the abundance of Lactobacillus, Ruminococcus, Clostridium XI, and decrease in Bacteroides. HI mainly induced decreased abundances of Blautia and Paraprevotella. The results of this study provide basic data for further research on hydrogen medicine. Determination of the effects of hydrogen intervention on microbiota profiles could also shed light on identification of mechanism underlying the biological effects of molecular hydrogen.

A study was conducted on dairy cows aged 3-6 lactation, which were additionally fed with the Ketostop-El supplement at the rate of 300 g per head for 4 weeks after calving. The use of the feed supplement for 14 days led to a decrease in the number of monocytes, total protein, glucose, creatinine, total calcium and the activity of ALT and AST compared to their level before the use of Ketostop-El. Changes in the physical and chemical properties of urine and increase in the average daily milk yield were noted. The use of the supplement for 28 days contributed to a decrease in hematocrit, the sorption capacity of red blood cells, total protein, glucose, bilirubin, creatinine, total calcium, reserve alkalinity, ALT and AST activity and an increase in the number of basophils, eosinophils, and the concentration of inorganic phosphorus compared to the initial data. At the same time, a decrease in the level of protein and ketones in the urine was observed. An increase in the average daily milk yield and the mass fraction of fat in milk was also recorded. The feed supplement "Ketostop-El" has a positive effect on the body of dairy cows, as evidenced by the normalization of the clinical and metabolic status, as well as an increase in the dairy productivity of animals.

Abstract This study aimed to evaluate the effect of zinc supplementation in various diets on the performance and health status of IPB-D2 chickens. Subsequently, about 180 one-week-old IPB-D2 chickens were used in the study and were fed the treatment diets for 12 weeks. Also, this study employed a completely randomised factorial design with six treatments and three replications of ten birds each. These treatment diets included A1, which contained nutrients based on SNI (2013) without Zn supplementation, A2 which is a combination of A1 and 60 ppm of Zinc, B1 which contained nutrients 5% higher than SNI without Zn supplementation, B2 which is a combination of B1 and 60 ppm Zinc, C1 which contains nutrients 10% higher than SNI without Zn supplementation, and lastly, C2 which is a combination of C1 and 60 ppm of Zinc. Furthermore, the data were analysed using ANOVA, and the parameters observed were the body weight, body weight gain, feed consumption, feed conversion ratio, blood profile and the villi surface area of the jejunum. Consequently, the results showed that C2 significantly (P<0.05) increased the body weight and body weight gain when fed to the finisher and grower chickens, respectively. More so, when the finisher chickens were fed the 10% SNI diet, there was an increased body weight gain and also a significantly (P<0.05) decreased feed conversion ratio. Furthermore, the addition of 60 ppm zinc increased haemoglobin significantly (P<0.05), whereas C2 decreased leukocytes significantly (P<0.05) in chicken blood. However, the treatments had no effect on feed consumption in the villi surface area of the jejunum. Therefore, the study concluded that supplementing the IPB-D2 chickens with 60 ppm zinc in a 10% SNI diet resulted in the best performance and health status.

The body of  broiler chickens is characterized by a high metabolism, which promotes rapid growth and development, but their performance indicators are largely related to housing conditions, which are known to include a number of technological stressors. With the development of stress in the body of poultry changes the course of metabolic processes, which causes changes in all types of metabolism, including protein. The aim of the study was to determine the changes in individual indicators of protein metabolism in the body of broiler chickens against the background of combined stress when included in the diet “Reasil Humic Vet” + “Laktin” and “Reasil Humic Health”. At 13th day of life, all clinically healthy poultry were exposed to combined stress – revaccination (intranasal Newcastle disease) plus cold stress (for 60 minutes by air conditioning and 5 °C in the vivarium). Material for research was selected for 3 days after the action of the stress factor (stage of anxiety), 13, 20 and 26 days after the action of the stress factor (the resistance stage). The material for the study was blood plasma, which determined the concentration of total protein, as well as the content of albumin, globulin fraction (α1, α2, β, γ). It was found that 3 days after the action of stress in chickens of Control group the development of adaptive reactions is manifested by the stability of the total protein content and redistribution of the fractional composition of plasma globulins in the form of increased albumin and α2-globulins. At different stages of development of the stage of resistance in birds of Control group, the content of total protein decreases by an average of 14.6 % due to the content of albumin by 6.9 % and α2-globulins – by 15.9 %, against the background of increasing α1- and γ-globulins by 23.1 and 33.5 % with the stabilization of individual studied indicators at the final stages of development of the resistance stage. The use in the diet of broilers feed “Reasil Humic Vet”, probiotic feed supplement “Laktin”, feed “Reasil Humic Health” under the influence of complex stress helps to increase the intensity of protein metabolism in poultry with the development of adaptation syndrome, as evidenced by the growth of total protein on average by 37.8 % (P < 0.05) and albumin – by 17.0 % (P < 0.05), which indicates an increase in the intensity of protein-synthesizing properties of the organism. In different periods of stress in the blood of broiler chickens Research groups there is an increase in the ratio of individual protein fractions, especially the content of γ-globulins - an average of 21.3 % (P < 0.05), which indicates an increase in the immune status of their body with a predominance of numerical values in the Research 1 group of poultry.

Human health, in addition to social and spiritual well-being, is determined by its physical condition, which reflects the functional capabilities of the body, features of physical development and ensures working capacity in any activity, including academic workload, which is extremely important for students in higher educational institutions. The purpose of the study is to assess the health status of students at the School of Biomedicine of the Far Eastern Federal University. Material and methods. The health status of 184 medical students (147 young women and 37 young men) was assessed using a sociological survey (questionnaire) and a study of the component composition of the body using bioimpedancemetry. Results. The low physical activity, detected in 68% of students and bad habits (smoking tobacco) have been established to negatively affect students’ health. Among smokers, 75% of students live in dormitories on the university campus. According to the results of bioimpedancemetry, significant deviations from the age norm were noted in terms of body mass index (BMI) (50% of cases) and fat mass (FM) (71% of cases). Significant gender differences in the individual components of the body were not identified. Discussion. The most aggressive factors that significantly affect the health of students are unbalanced nutrition, lack of compliance with the regime of study and rest, lack of sleep and stay in the fresh air, lack of physical activity, lack of motivation for a healthy lifestyle. Significant deviations in BMI and FM, identified by bioimpedancemetry, indicate the risks of developing arterial hypertension, metabolic syndrome, and nutritional status disorders. Medical students need to give recommendations for increasing motor activity and changing diet. Conclusion. The results of the study can be used in the future to determine the functional state of students and develop preventive measures to preserve the health of medical students.
