FUNCTIONAL PROPERTIES OF THE PROTEIN FEED ADDITIVES BASED ON THE WASTES AND BY-PRODUCTS OF SLAUGHTER AND PROCESSING OF POULTRY

The distribution of molecular weights (MW) of the peptides and anti-oxidative capacity (as oxygen radical absorbing capacity, ORAC) were studied in new protein feed additives produced by the short-term thermal hydrolysis and subsequent fermentation by proteolytic enzymes of the wastes and by-products of slaughter and processing of poultry.The study was financed by the Russian Science Foundation, grant No 17-16-01-028-P

Typology of Primary School Children with Identified Developmental Disability and Learning Difficulties

Оригинал статьи получен 02 февраля 2023. Исправленная статья принята 20 февраля 2023.На современном этапе развития системы психолого-педагогической поддержки субъектов образовательного процесса наиболее актуальной становится задача своевременного диагностирования и выявления детей с проблемами в развитии, которые препятствуют освоению образовательной программы. По данным исследований, за последние десять лет количество младших школьников, не справляющихся с программой при сохранном интеллекте, неуклонно растет. В исследовании, направленном на выявление психологических особенностей детей с отклонениями в развитии, испытывающих трудности в обучении, приняли участие учащиеся младших классов средних школ Свердловской области в количестве 230 человек, из них 111 девочек (48 %) и 119 мальчиков (52 %). Основной методикой диагностики явился тест Тулуз-Пьерона, универсальный для психофизиологической оценки. Среди наиболее выраженных признаков минимальной мозговой дисфункции выделяются: недостатки сформированности памяти, мышления, произвольного внимания, повышенная умственная утомляемость, отвлекаемость, двигательная неуправляемость, слабость саморегулирования. В результате проведенного исследования подтверждены гипотезы о том, что у детей с минимальными мозговыми дисфункциями, в зависимости от выраженности типа, существуют особенности развития высших психических функций и характера поведения в процессе обучения, требующие специальных приемов контроля и оценки знаний учащихся.At the present stage of the development of the system of psychological and pedagogical support for the subjects of the educational process, the goal of timely diagnosis and identification children with developmental problems that are the reason for the lack of the necessary psychological basis to master the educational program becomes the most urgent. According to research over the past 10 years, the number of primary school pupils who fail to cope with the program with preserved intelligence is steadily growing. The study aimed at identifying the psychological characteristics of children with developmental disabilities having learning problems involved 230 pupils of junior high school in the Sverdlovsk region, 111 of them girls (48 %) and 119 boys (52 %). The main diagnostic method was the Toulouse-Pieron test, universal for psychophysiological assessment. The most expressed signs of the minimal brain dysfunction are deficiencies in the formation of memory, thinking, voluntary attention, increased mental fatigue, distractibility, motor uncontrollability, weakness of self-regulation. As a result of the study hypotheses were confirmed that in children with the minimal brain dysfunctions, depending on the severity of the type, there are features of the development of the higher mental functions and the nature of behavior in the learning process that require special techniques for monitoring and evaluating pupils’ knowledge

THE EFFECTS OF FEED ADDITIVES BASED ON THE WASTES OF POULTRY PROCESSING ON THE PRODUCTIVE PERFORMANCE AND MEAT QUALITY IN BROILER CHICKS

The wastes of the slaughter and primary processing of poultry could potentially be used as animal protein sources for broilers. Feed additives based on these wastes can solve the problem of their utilization and offer an opportunity to save on the more expensive animal protein sources. As it known, by-products are the most valuable source of animal protein. Of particular interest are the feather and meat and bone residue.There are several ways to obtain hydrolysates. One of them is important for enzymatic hydrolysis.The study was financed by the Russian Science Foundation, grant No 17-16-01-028-P

THE EFFECTS OF FEED ADDITIVES BASED ON THE WASTES OF POULTRY PROCESSING ON THE PRODUCTIVE PERFORMANCE AND MEAT QUALITY IN BROILER CHICKS

The productive performance and meat quality were studied in broiler chicks fed diets supplemented with easily digestible animal derived protein additives produced by short-term intense thermal treatment and enzymatic hydrolysis of keratin- and collagen-containing wastes of slaughter and processing of poultry. The trial was performed on 4 treatments of Ross-308 broilers (50 birds per treatment, from 1 to 38 days of age). Control treatment was fed diet with fishmeal as animal protein source; in treatments 2 and 3 the fishmeal was substituted by enzymatic hydrolysate of feathers (keratin-containing wastes) with and without probiotic preparation, respectively; in treatment 4 the fishmeal was substituted by a mixture of enzymatic hydrolysates of feathers and collagen-containing wastes with probiotic preparation. It was found that average live bodyweight at slaughter age was higher in all experimental treatments in compare to control

Concerning the choice of viscoelastic solutions in glaucoma shunt surgery

Shunt surgery does not have any alternative in refractory glaucoma treatment. The results of this surgical direction are restrained by high risks of intra- and postoperative complications. Considerable fluctuation of intraocular pressure and inflammatory process relate to intraoperative complications. This problem is partly solved by use of viscoelastic fluids nevertheless we do not have precise ideas about qualities of viscoelastic fluids which would be appropriate in this surgery. The comparative study between three groups of viscoelastic fluids in vitro to invextigate the adhesive capacity of leucocytes was carried out. The provocation of adhesive molecules exspression on the leucocytes membranes in experiment was estimated as reaction that activates inflammatory process in the conditions of surgical trauma. Sodium hyaluronate 3% was determined to possess the best qualities. This preparation activate the leucocytes adhesion to a lesser degree, and is capable to be in the anterior chamber for a long time. Use of sodium hyaluronate 3% prevents rough scarring by decreasing inflammation rate

PATHOPHYSIOLOGICAL REASONING OF THE EFFICIENCY OF ANTI-ANGIOGENIC THERAPY IN THE RETINAL VEIN OCCLUSION BY THE COHERENT EYE TOMOGRAPHY

Aim. The main aim of our research is to study the effectiveness of anti-VEGF therapy in the treatment of retinal vein occlusions.Materials and methods. The study included 124 patients aged between 23 to 66, an average of 54.3±8.9 years old who were on an outpatient and inpatient treatment in the ophthalmologic department of the V.K. Gusak Institute of Emergency and Reconstructive Surgery from 2011 to 2016. We have formed two groups. The comparison group included 66 patients who received standard therapy in the form of local anticoagulant and anti-edematous therapy, disaggregants. To improve microcirculation and with a decongestant purpose, rheopolyglucin was administered intravenously, and intramuscular injections of actovegin were prescribed with an antihypoxic purpose. With edema of the macula and the development of newly formed vessels – laser coagulation, intravitreal or subtenon introduction of trimacionolone. The main group included 58 patients who, in addition to standard therapy, were given the drug Eilia (aflibercept) intravitreally 2 mg in 0.05 ml. Treatment with aflibercept for intravitreal injections started with one injection once a month for the next five months, with a further transition to one injection every two months, with no monitoring required between the injections.Results. When post-thrombotic neovascular glaucoma occurred, the concentration of TGFα in the lacrimal fluid increased by 1.7, and TGFβ by 28-fold. When the branch of the central vein of the retina is occluded according to the ischemic type, the systolic and diastolic blood flow velocity in the retina decreases. With coherent optical tomography with the function of angiography, admission in both groups showed significant macular edema, non-perfusion zones of the retina, a decrease in the density of the capillary network in the inner layers of the retina in angio-OCT, and 3 patients with angio-OCT visualized newly formed vessels in the nonperfusion zone.Conclusion. In the group with the use of anti-angiogenic drugs, earlier restoration of the visual fields and reduction of neoangiogenesis were noted
