Directions to improve economic efficiency of regional production

The paper provides theoretical grounding and the directions for improving the economic efficiency of the regional feedstuff production. The study develops a conceptual model of distributing management functions of feedstuff production between the regional authorities of state sectoral and economic management and the district level. The authors suggest the methodology for calculating potential capacity of intraregional feedstuff market, considering the demands of all categories of agricultural manufacturers. The study examines possibilities for implementing the strategy of diversified growth and development of the intraregional feedstuff market, including the terms of interaction between the large and micro-business inside the industry and cooperation of micro-business feedstuff manufacturers with agricultural production. The authors have developed the methodology for assessing the efficiency of feedstuff production, based on the aggregate estimation of the management organization, conditions for the development of feedstuff production and changes in the feedstuff production and livestock breeding industry.peer-reviewe

Inflammatory Activity in Patients with Obstructive and Non-obstructive Coronary Artery Disease

Aim. To study the levels of pro-inflammatory biomarkers  in patients with obstructive  and non-obstructive coronary  artery disease (CAD), to identify possible differences  for diagnosing the degree of coronary  obstruction.Material and methods. The observational  study included two groups of patients: with non-obstructive (main group,  coronary artery stenosis <50%; n=30) and obstructive  (comparison group,  hemodynamically significant  coronary  artery stenosis according to the results of coronary  angiography; n=30) CAD.  The levels of interleukin-1β (IL-1β) and interleukin 6 (IL-6) were measured in plasma using enzyme  immunoassay.Results. IL-6  levels were significantly higher in patients with obstructive  CAD  (p=0.006) than in patients with non-obstructive CAD.  There were no significant  differences  in the level of IL-1β in both groups  (p=0.482). When  constructing the ROC  curve,  the threshold  value of IL-6  was  26.060 pg/ml. At the level of IL-6  less than this value, CAD  was diagnosed with hemodynamically insignificant stenoses of the coronary  arteries.Conclusion. The results of this study confirm that in patients with different types of coronary  artery lesions, there are differences  in the activity of the inflammation process in the arterial wall. IL-6  was higher in the obstructive  lesion group,  and IL-1β levels did not differ between groups.  Thus, it can be assumed  that hemodynamically significant  obstruction  of the coronary  arteries develops  as a result of highly  active inflammation of the vascular wall. Given the presence of a proven biological  basis and the available data on the effectiveness of monoclonal antibodies to IL-1β, one cannot exclude their possible benefit in a cohort of patients with CAD  and hemodynamically insignificant stenoses

Evaluation of Fibrosis Markers as a Potential Method for Diagnosing Non-Obstructive Coronary Artery Disease in Patients with Stable Coronary Artery Disease

Aim. To study the levels of fibrosis markers in patients with stable coronary artery disease (CAD) and various types of coronary artery (CA) lesions (obstructive and non-obstructive), to identify possible differences for diagnosing the types of coronary obstruction.Material and methods. The observational study included three groups of patients: with non-obstructive (main group, coronary artery stenosis <50%; n=20) and obstructive (comparison group, hemodynamically significant coronary artery stenosis according to the results of coronary angiography; n=20) CAD and healthy volunteers (control group; n=40). Transforming growth factor beta 1 (TGF-β1) and matrix metalloproteinase 9 (MMP-9) levels were measured in plasma by enzyme immunoassay. According to the results of echocardiography, all patients included in the study were divided into four groups depending on the type of myocardial remodeling.Results. TGF-β1 levels were significantly higher in patients with obstructive CAD (p=0.008) than in patients with non-obstructive CAD and healthy volunteers (p <0.001). There were no significant differences between the main and control groups (p>0.05). There were no statistically significant differences in TGF-β1 levels depending on the type of left ventricular remodeling (p=0.139). The maximum level of MMP-9 was in the group with obstructive coronary disease and significantly differed from the main group (p <0.001) and the control group (p=0.04).Conclusio. The maximum levels of TGF-β1 and MMP-9 were found in the group with obstructive coronary artery disease. The levels of these biomarkers in the main group were statistically different from the values obtained in the control group. Thus, considering the pathogenesis of the development of non-obstructive CAD, the use of fibrosis markers TGF-β1 and MMP-9 may be promising for diagnosing the severity of CA obstruction

Surgical Treatment Options for Degenerative Lumbosacral Spinal Stenosis

Degenerative spinal stenosis is the most common type of degenerative and dystrophic spine disease. The clinical picture of stenosis, which may include axial pain syndrome, leg pain, intermittent claudication syndrome, weakness and loss of sensitivity in the legs, and impaired pelvic functions, can significantly worsen patients’ quality of life and reduce their ability to work and lead an active lifestyle. Degenerative spinal stenosis mostly affects the elderly. Therapeutic and neurological communities have stereotypes about spine surgery being too traumatic and invasive, and, therefore, they believe that their use should be contraindicated to and limited in elderly patients. However, surgeons are increasingly giving preference to minimally invasive interventions with high efficacy and safety together with a low risk of complications. We aimed at reviewing current treatment methods for degenerative lumbosacral spinal stenosis with an emphasis on surgical treatment methods

Menadione sodium bisulfite effect on growth performance and fatty acid profiles of geese muscle tissues

The specific effect of menadione sodium bisulfite (MSB, vicasol) on the content of specific fatty acids in skeletal muscle and muscular stomach of geese was established. MSB can stimulate the biosynthesis processes and catabolism of fatty acids depending on the period of the geese ontogenesis. Experimental use of MSB in skeletal muscle helps to increase the total content of unsaturated fatty acids (FA) primarily due to n-3 FAs. MSB increases the content of PUFA and SFA on the 35th day of ontogenesis, so the nutritional value of meat improves, and the resistance of myocyte membranes increases to oxidative damage. In the smooth muscle tissue of the goose stomach, the action of MSB revealed a higher content of UFA only on the 21st day of ontogenesis, due to PUFA, in particular, n-6 and MUFA. On the 28th day of ontogenesis, the content of PUFA increases due to n-3, with a decrease in the total content of UFA. At the end of the experiment, the UFA content decreases with increasing SFA. Reducton of the content of essential n-3, n-6, and UFA negatively affects the nutritional value of the product but increases the resistance of tissues to the active forms of oxygen. The use of MSB contributes to the overall increase of the average daily weight gain of geese from the 21st to the 28th day. The average body weight from the 21st to the 35th ontogenesis relative to the control group. We recommend using MSB at a dose of 0.7 mg/kg body weight for gosling feeding to increase the essential FA content in skeletal muscle tissue
