Influence of soy flour and its processed products on the essential amino acids content in the bees body

Providing bees with benign and sufficient protein feeds is the key to successful beekeeping. Protein feed significantly affects on certain functions of individuals and the vital activity and productivity of the bee colonies. So, as a result of increased consumption of protein feed during the first days of life the supply of proteins in the body significantly increases in young bees, hypopharyngeal glands and other organs become developed, which provides the ability to perform various tasks depending on age and living conditions. Older bees consume protein for tissue renewal with new cells and metabolic processes. Bees raised on low protein feeds become physiologically defective and do not live long. In conditions of protein starvation, brood rearing stops and bees throw larvae out of their cells. The article presents the results of studying the effect of using soy flour and its processed products in bee feeding on the essential amino acids content in their body. It was found that the use of soy peptone in bee feeding contributes to a greater accumulation of essential amino acids in the bees body in different periods of their development, in compared to soy milk, defatted soy flour and roasted soy flour which indicates a higher efficiency of its use as partial substitutes for protein feeds

Некоторые диагностические и лечебные аспекты при аппендикулярных инфильтратах

Introduction. Appendicular infiltration is currently considered as a complication of acute appendicitis. The incidence rate of this disorder ranges between 0.2 and 5.8%. Despite a large number of studies dedicated to the issue of acute appendicitis and its complications, including appendicular infiltration, surgeons’ interest to this issue remains undiminished.Materials and methods. The paper presents the results of a retrospective analysis of diagnosis and treatment of 57 patients admitted to MI CTH No. 8, Ufa, with a diagnosis of acute appendicitis complicated with appendicular infiltration in 2012-1017.Results and discussion. In 32 (56.1%) patients, the infiltration was diagnosed during the surgery or diagnostic laparoscopy as an incidental find, the so-called ‘find-infiltration’. Of these, in 19 (33.3%) patients, the intraoperative find was evaluated as hard infiltration, in 13 (22.8%) — as soft. In 25 (43.9%) of patients admitted to the clinic with acute appendicitis, it was suspected that the infiltration had developed prior to surgery. Dynamic clinical and ultrasound examination in 11  patients left no doubt regarding the presence of infiltration. These patients were treated conservatively. In the remaining 14 patients, it was impossible to exclude acute appendicitis or infiltration and it was decided that diagnostic laparoscopy was indicated.Conclusion. Diagnostic laparoscopy is the leading method for diagnosis of this complication that helps determine a treatment strategy. Surgical strategy was strictly differentiated  — at the infiltration stage  — conservative, at the abscess stage — surgical; abscess cavity dissection and draining was recommended. Appendectomy was considered acceptable in technically uncomplicated situations. All the patients following the resolution of appendicular infiltration and dissection of periappendicular abscess should receive the recommendation to have appendectomy 3–4 months after dischargeВведение. В настоящее время аппендикулярный инфильтрат многими авторами трактуется как осложнение острого аппендицита и встречается пределах от 0,2 до 5,8 %. Несмотря на большое количество научных исследований, посвященных проблеме острого аппендицита в целом и его осложнений, таких как аппендикулярный инфильтрат, интерес хирургов к данной проблеме не уменьшается.Материал и методы. В статье приведены результаты ретроспективного анализа диагностики и лечения 57 пациентов, поступивших в хирургические отделения МУ ГКБ № 8 г. Уфы по поводу острого аппендицита, осложненного аппендикулярным инфильтратом, в период 2012–2017 гг.Результаты и обсуждение. У 32 пациентов (56,1  %) инфильтрат был выявлен интраоперационно или при диагностической лапароскопии как операционная находка, так называемый файнд-инфильтрат. Из них у 19 (33,3 %) больных интраоперационная находка расценена как плотный инфильтрат, у 13 (22,8 %) как рыхлый. У 25 (43,9 %) больных, поступивших в клинику по поводу острого аппендицита, учитывая сроки заболевания, предполагалось развитие инфильтрата до операции. При динамическом клиническом и ультразвуковом исследовании у 11 больных наличие инфильтрата не вызывало сомнения. Этим больным назначено консервативное лечение. У остальных больных (n = 14) исключить наличие острого аппендицита или инфильтрата не представлялось возможным и определены показания для диагностической лапароскопии.Заключение. Ведущим методом диагностики является диагностическая лапароскопия, которая позволяет диагностировать данное осложнение и определить тактику лечения. Хирургическая тактика была строго дифференцированной: в стадии инфильтрата — консервативной, в стадии абсцедирования — оперативной, рекомендовали вскрытие и дренирование полости гнойника. Аппендэктомия допустима лишь при технически не сложных ситуациях. Всем больным после рассасывания аппендикулярного инфильтрата и вскрытия периаппендикулярного абсцесса следует рекомендовать аппендэктомию через 3–4 месяца после выписки из стационара

Роль перфузионной компьютерной томографии в диагностике дивертикулярной болезни ободочной кишки и ее осложнений

Introduction. Colonic diverticular disease (colonic diverticulitis) is considered to be a serious medical and social problem of modern society, marked by a persistent decrease in the quality of life of patients and a steady growth in morbidity with a tendency to increase complications of the underlying disease in the form of inflammatory destructive changes in the intestinal wall.Materials and methods. The study involved 63 patients with colonic diverticulitis, males and females, aged 34 through 79 years. All participants were divided into 3 groups, depending on the damage to the intestinal wall. The first group included 11 patients with intact intestinal wall, the second group included 43 patients with diverticulitis, and the third group — 9 patients with adenocarcinoma of the large intestine.Results and discussion. When performing perfusion computed tomography (PCT) of the intestinal wall, it was found that BF values in acute diverticulitis, compared to the intact intestinal wall, increased on average by 1.7 times, while in malignancies — by 5.3 times. BV values in acute diverticulitis, as compared to the intact intestinal wall, increased by 9.2, and in malignancies — 13.6 times. MRI values in acute diverticulitis, as compared to the intact intestinal wall, increased by 2.5 times, and in malignancies — 3.9 times. PS values in acute diverticulitis, as compared to the intact intestinal wall, increased by 1.7 times, and in malignancies — 3.8 times.Conclusion. Since PCT is able to detect the difference of microcirculation parameters in inflammatory and malignant processes, it can be used in the diagnostic algorithm to determine further treatment strategy.Введение. Дивертикулярная болезнь ободочной кишки (ДБОК) является значимой медико-социальной проблемой современного общества, характеризующейся стойким снижением качества жизни пациентов и неуклонным ростом заболеваемости в популяции в целом с тенденцией к увеличению осложнений основного заболевания в виде воспалительных деструктивных изменений со стороны стенки кишки.Материалы и методы. В исследовании приняли участие 63 пациента с ДБОК обоего пола в возрасте от 34 до 79 лет включительно. Все обследуемые были разделены на 3 группы в зависимости от поражения стенки ободочной кишки. В первую группу вошли 11 пациентов с неизмененной стенкой кишки, во вторую группу — 43 пациента с дивертикулитом, третью группу составили 9 пациентов с аденокарциномой ободочной кишки.Результаты и обсуждение. При проведении перфузионной компьютерной томографии (ПКТ) стенки ободочной кишки было установлено, что показатели BF при остром дивертикулите по сравнению с неизмененной стенкой кишки увеличились в среднем в 1,7 раза, тогда как при злокачественных образованиях — уже в 5,3 раза. Данные BV при остром дивертикулите по сравнению с неизмененной стенкой кишки увеличились в 9,2 раза, при злокачественных образованиях — в 13,6 раза. Показатели МРТ при остром дивертикулите по сравнению с неизмененной стенкой кишки увеличились в 2,5 раза, при злокачественных образованиях — в 3,9 раза. Показатели PS при остром дивертикулите по сравнению с неизмененной стенкой кишки увеличились в 1,7 раза, при злокачественных образованиях — в 3,8 раза.Заключение. Перфузионная компьютерная томография способна выявить разницу показателей микроциркуляции при воспалительных и злокачественных процессах и может применяться в общем диагностическом алгоритме для определения дальнейшей тактики лечения

Dispersion of the Thermodynamically Immiscible Polypropylene and Ethylene—Propylene Triple Synthetic Rubber Polymer Blends Using Supercritical SEDS Process: Effect of Operating Parameters

In this paper, we present the results of dispersion of thermodynamically immiscible polypropylene (PP) and ethylene-propylene triple synthetic rubber (EPTSR) polymer blends using the Solution-Enhanced Dispersion by Supercritical Fluid (SEDS) technique at operation conditions in the pressure range of (8 to 25) MPa and at temperatures t = 40 °C and 60 °C. The kinetics of crystallization and phase transformation in polymer blends obtained by conventional method (melt blending) and by mixing in the SEDS process have been studied using the DSC technique. The effects of the SEDS operation process on the physical—chemical (melting temperature, heat of fusion) and mechanical (microparticle size) characteristics of the SEDS-produced polymer blends were studied

Optimizing the rate and timing of phosphogypsum application to magnesium-affected soils for crop yield and water productivity enhancement

The levels of magnesium (Mg2+) in irrigation waters and soils are increasing in several irrigation schemes worldwide. Excess levels of Mg2+ in irrigation waters and/or in soils negatively affect soil physical properties (infiltration rate and hydraulic conductivity) and ultimately crop growth and yield. Although few studies have been undertaken on productivity enhancement of magnesium-affected soils by adding a source of calcium (Ca2+) to mitigate the effects of excess Mg2+, there is no information available on optimizing the rate and time of the Ca2+-amendments. A 2-year field study was undertaken in southern Kazakhstan by applying phosphogypsum (PG), a source of Ca2+ and a byproduct of the phosphorous fertilizer industry, to a magnesium-affected soil. There were five treatments with four replications: (1) control (without PG application); (2) PG application in January (before snowfall) equivalent to PG requirement for 0.3m soil depth (3.3tha-1); (3) PG application in January equivalent to PG requirement for 0.6m soil depth (8.0tha-1); (4) PG application in April (after snowmelt) at 3.3tha-1; and (5) PG application in April (after snowmelt) at 8.0tha-1. All treatment plots were grown with cotton (Gossypium hirsutum L.), which is the most important summer crop in the region. The PG treatments performed significantly better than the control in terms of (1) improved soil quality with a reduction in exchangeable magnesium percentage (EMP) levels; (2) enhanced water movement into and through the soil vis-à-vis increased moisture storage in the root zone for use by the plant roots; (3) increased irrigation efficiency; (4) increased cotton yield and water productivity; and (5) greater financial benefits. In terms of the best rate and time of application, PG applied before the snowfall improved the soil properties to a greater extent than its application in spring after snowmelt. The economic benefits from the amendment application at 3.3tha-1 were double those from the treatments where it was applied at 8.0tha-1, suggesting that the lower rate was economically optimal. In addition to improving crop productivity, the study demonstrated the beneficial use of an industrial waste material in agriculture.Magnesium to calcium ratio Exchangeable magnesium percentage Salt-affected soils Phosphogypsum Water quality Central Asia Kazakhstan Cotton
