Background. Stroke is the leading cause of serious and long-term disability worldwide. Survivors may recover some motor functions after rehabilitation therapy. However, many stroke patients missed the best time period for recovery and entered into the sequela stage of chronic stroke. Method. Studies have shown that motor imagery- (MI-) based brain-computer interface (BCI) has a positive effect on poststroke rehabilitation. This study used both virtual limbs and functional electrical stimulation (FES) as feedback to provide patients with a closed-loop sensorimotor integration for motor rehabilitation. An MI-based BCI system acquired, analyzed, and classified motor attempts from electroencephalogram (EEG) signals. The FES system would be activated if the BCI detected that the user was imagining wrist dorsiflexion on the instructed side of the body. Sixteen stroke patients in the sequela stage were randomly assigned to a BCI group and a control group. All of them participated in rehabilitation training for four weeks and were assessed by the Fugl-Meyer Assessment (FMA) of motor function. Results. The average improvement score of the BCI group was 3.5, which was higher than that of the control group (0.9). The active EEG patterns of the four patients in the BCI group whose FMA scores increased gradually became centralized and shifted to sensorimotor areas and premotor areas throughout the study. Conclusions. Study results showed evidence that patients in the BCI group achieved larger functional improvements than those in the control group and that the BCI-FES system is effective in restoring motor function to upper extremities in stroke patients. This study provides a more autonomous approach than traditional treatments used in stroke rehabilitation.

The paper considers the effect on rats of long-term feeding of an aqueous solution of citric acid (C6H12O6 x H2O, "chemically pure.") in the amount of 8 mg/l. The study was performed on 10 laboratory female rats F1 of the Wistar line, obtained from F0 females. Two groups were set up: control and experimental, 5 animals in each. Animals were under standard conditions with natural light regime day/night, aqueous solutions of citrate, water, and feed received ad libitum. Were determined the morphological composition and biochemical parameters of the blood of female F1 rats. The results of the study indicate the absence of an unfavorable effect of citric acid on red blood cells. Concerning white blood, there is a decrease in the number of leukocytes, which may be due to the development of an adaptive response of the body to citric acid or the inhibition of citric acid's immune response to long-term adaptive action. There is a significant increase in the relative content of eosinophils in females F1, which probably may be due to the action of citric acid. The analysis of the obtained results of blood biochemical parameters indicates a certain tendency to decrease, in terms of control, the content of serum iron, as well as its total and unsaturated Fe-binding capacity. Ferrum saturation of serum transferrin was present at the level of animals in the control group. Analysis of the study results indicates no changes in control in the activity of enzymes: Alkaline phosphatase ALT and AST, also have no statistically significant confirmation of differences in the control group. The level of urea was statistically not significantly higher in terms of control. Thus, long-term watering of citric acid to female rats in the generation F0 and F1 during their physiological and sexual gestation and pregnancy reveal un-favorable effects in female rats F1. However, there was distinguished the adaptive immune-biological response of the animals organism. The immunological response was supported by a decrease in the number of leukocytes and a significant increase in the relative content of eosinophils. The results of biochemical studies of serum indicate the absence of statistically significant differences in animals of the control group.

Background. There are no evidence-based strategies that have been shown to be superior in maintaining motor function for months to years after the stroke. The LAST study therefore intends to assess the effect of a long-term follow-up program for stroke patients compared to standard care on function, disability and health.Design. This is a prospective, multi-site randomised controlled trial, with blinded assessment 18 months after inclusion. A total of 390 patients will be recruited and randomised to a control group, receiving usual care, or to an intervention group 10 to 16 weeks after onset of stroke. Patients will be stratified according to stroke severity, age above 80, and recruitment site. The intervention group will receive monthly coaching on physical activity by a physiotherapist for 18 consecutive months after inclusion.Outcomes. The primary outcome is motor function (Motor Assessment Scale) 18 months after inclusion. Secondary outcomes are: dependency, balance, endurance, health-related quality of life, fatigue, anxiety and depression, cognitive function, burden on caregivers, and health costs. Adverse events and compliance to the intervention will be registered consecutively during follow-up.

BACKGROUND A serious game-based Cellphone Augmented Reality System (CARS) was developed for rehabilitation of stroke patients, which is portable, convenient, and suitable for self-training. OBJECTIVE The present research aimed to study the effectiveness of CARS in improving upper limb motor function and cognition function of stroke patients via conducting a long-term randomized controlled trial and analyze the patient’s acceptance of the proposed system. METHODS A randomized, double-blind, controlled trial was performed with 30 post-stroke, sub-acute phase patients. All patients in both the experimental group (n=15) and the control group (n=15) performed a 1-hour session of therapy each day, 5 days per week, for 2 weeks. Patients in the experimental group received 30 minutes of rehabilitation training with CARS and 30 minutes of conventional occupational therapy (OT) each session, while patients in the control group received conventional OT for the full 1 hour each session. The Fugl-Meyer Assessment-Upper Extremity subscale (FMA-UE), Action Research Arm Test (ARAT), Manual Muscle Test (MMT), Brunnstrom Stage (BS), and Barthel Index (BI) were used to assess motor function, and the Mini-Mental State Examination (MMSE), Add VS Sub (AVS), and Stroop Game (SG) were used to assess cognitive function before and after the 2-week treatment period. In addition, the User Satisfaction Evaluation Questionnaire (USEQ) was used to reflect the patients’ acceptance of the system in the experimental group after the final intervention. RESULTS All the assessment scores of the experimental group and control group were significantly improved after intervention (p<0.05). The experimental group’s score of FMA-UE and ARAT increased by 11.47 and 5.86 respectively after intervention, which were both significantly higher than the increase of the control group (p<0.01). Similarly, the score of AVS and SG in the experimental group increased by 7.53 and 6.83 respectively after the intervention, which was also higher than the control group (p<0.01). The evaluation of the adoption of this system has three sub-dimensions. In terms of accessibility, the patients reported a mean score of 4.27±0.704 for the enjoyment of their experience with the system, 4.33±0.816 for success to use the system, 4.67±0.617 for the ability to control the system. In terms of comfort, the patients reported 4.40±0.737 for clear information provided by the system, 4.40±0.632 for comfort. In terms of acceptability, the patients reported 4.27±0.884 for usefulness in their rehabilitation, 4.67±0.617 for agreeing with CARS as a suitable tool for home-based rehabilitation. CONCLUSIONS CARS and conventional OT together-based rehabilitation were more effective in improving both upper limb motor function and cognition function as compared with conventional OT. Due to the low cost, and ease of use, CARS is also potentially suitable for home-based rehabilitation. CLINICALTRIAL The Chinese Clinical Trial Registry (ChiCTR1800017568).

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.

Introduction. Rabbit meat is an excellent source of dietetic food. High-quality and safe meat production is a priority of the scientific and technological development of the Russian Federation. The research objective was to determine the optimal dose of Echinacea purpurea L. extract in the rabbit diet and study its effect on the physicochemical and morphological quality parameters of rabbit meat. Study objects and methods. At 70 days of age, the experimental animals started to receive various doses of a phytobiotic feed additive based on the Echinacea purpurea extract. The experiment lasted 30 days. Results and discussion. The daily dose of 1.0 g and 1.5 g per animal proved to stimulate the redox processes in the rabbit metabolism. The body weight of the test animals significantly increased compared with the control group. The test slaughter revealed a high level of meat productivity. The animals in experimental groups II and III showed the best slaughter indicators. Each animal received 1.5 g of the extract per day. The morphological composition of chilled carcass indicated that the additive had a positive effect on the mass indicators. According to the physical and chemical analysis, the contents of water, protein, and ash in the experimental group was the same as in the control group. The ratio of unsaturated and saturated fatty acids in the control group was 1.34:1, while in the experimental group III is was 1.39:1. This optimal proportion proved a high biological value of rabbit meat, which makes it a dietary product. The phytobiotic additive proved commercial as the test animals demonstrated an intensive weight gain compared with the control group. Experimental groups II and III showed the best slaughter indicators. Conclusion. 1.5 g of the extract of Echinacea purpurea had a positive effect on the composition and physicochemical parameters of rabbit meat, as well as meat production.

Unbalanced mineral and vitamin nutrition of lactating cows can be a critical factor in the realization of their productive potential. The development and introduction into production of inexpensive, but effective feed additives is the main trend of improving the feeding of modern animal husbandry. Under the conditions of the Tyumen region such natural raw materials can be sapropels, which successfully combine a variety of biologically active substances. The purpose of the research was to study the digestibility of nutrients and energy metabolism in lactating cows when sapropel is included in the ration. Scientifi c and economic experiment in the study of the effectiveness of feeding sapropel lake Nepryak has been carried out in the training and experimental farm of the State Northern Trans-Urals Agrarian University. The animals of the control group have been fed the main diet. Cows of the 1st and 2nd experimental groups have been fed 300 and 500 g of sapropel per head/day, respectively, in addition to the main ration. It has been found as a result of research that the introduction of sapropel into the ration of cows has a positive effect on the digestibility of nutrients. The digestibility coefficients were higher in the animals of the 1st and 2nd experimental groups compared with the cows of the control group. Cows from the experimental groups digested all the organic substances of the ration better. During the experiment period cows of the 1st and 2nd experimental groups in contrast to the control group had higher milk yield by 11,31 and 10,38 %, respectively, milk protein yield by 10,56 and 5,95 %, milk fat yield by 17,18 and 12,99 %. It has been established that the introduction of sapropel into the ration of cows has the positive effect on the digestibility of nutrients, contributes to the increase of milk productivity, normalizes the metabolism in the body.

A comparative study was set up in order to assess the technical feasibility of the long-term reuse of the mechanically separated co-digested solid fraction as a feedstock for anaerobic digestion plants (ADP). The biogas yields of two feedstock mixtures (A and B) were assessed in mesophilic conditions (40°C±2°C) using 6 lab-scale continuous stirredtank reactors. Feedstock mixture A (control) consisted of pig slurry (70%), farmyard manure (4%), sorghum silage (12%) and maize silage (14%). Feedstock mixture B was the same as the control plus the solid fraction derived from the mechanical separation of the output raw codigestate collected from the reactors. All reactors were fed simultaneously, three times a week, over a period of nine month. According to the study results, the reuse of the co-digested solid fraction as feedstock for ADP could increase the methane yield by approximately 4%. However, ADP efficiency evaluation (<em>e.g.</em>, daily yield of methane per m<sup>3</sup> of digester) suggests limiting this practice to a maximum time period of 120 days.

Drinking ice-cold water is prohibited in Avicenna’s “The Canon of Medicine” book in which he emphasized that ice-cold water drinking was hazardous for the body organs such as the liver. Little information can be found regarding the effects of ice-cold fluid drinks on liver and its probable sequels on this vital organ. Accordingly, we investigated the effects of long-term ice-cold water drink on the rat liver function and histology. Eighteen male Wistar rats, weighing 180±20 g, were randomly divided into three groups of six as two months ice-cold water drink, CW2M; three months ice-cold water drink, CW3M; and three months room temperature water drink; control group. Upon completion of the care period, a blood sample has been taken for liver enzymes and lipid profile assessment. Liver tissue has also been used for histological studies of H&E staining and microscopic examination. Histological findings showed hepatocellular micro-vesicle formation, necrosis and derangement of the cellular cords and infiltration of Kupffer cells in ice-cold water taken animals. Serum TGs, VLDL-C and ALP significantly increased with sound decrease in FBS and LDL-C in ice-cold water taken animals. It seems that long-term ice-cold water has deleterious functional and structural effects on the liver.

Indonesia has a significant and growing shortfall of housing. Existing supply is in poor condition and demand is rising for new units. Meanwhile, people's purchasing power to buy a house is still relatively low. Government overcomes added stock housing availability by collaborating with private developers to help meet the demand for housing needs. Islamic banks can provide funds to buy houses for the community. This study analyzes the effect of third-party fund (TPF), margin of homeownership financing (PPR), inflation, and household income on Islamic financing for homeownership. The analytical model used in this research is the ordinary least square with the Error Correction Model (ECM) method. The Ordinary Least Square (OLS) method in this study is used to see the relationship between the short-term and long-term effects of the independent variables on the dependent variable. The analytical tool used in this research is Econometric Views (EViews 10 Standard Edition for Windows). The study results show that in the short term, the TPF, PPR margin, inflation, and household income variables have a significant positive effect on homeownership financing in Islamic banks in Indonesia. The long term TPF, inflation, and household income variables have a significant positive effect on homeownership financing in Islamic banks in Indonesia, but the variable of PPR margin has a significant negative impact on sharia financing for homeownership.
