Authors: Orlova Valentina S. , Trushina Oksana V. , Kalashnikova Irina V.
Published: March 2018

Background. Menstrual pain syndrome is accompanied by a complex of neurovegetative, metabolic-endocrine and psycho-emotional disorders. Dysplasia of connective tissue is characterized by a high level of functional disorders of the central and autonomic nervous system and emotional disorders.

Aim. Detection of features of a clinical current of primary dysmenorrhea in adolescent girls with signs an undifferentiated dysplasia of connecting tissue (UDCT). Materials  and methods. 210 adolescent girls at the age of 11–17 full years suffering primary dysmenorrhea were examined. Depending on the presence or absence of clinical signs of undifferentiated connective tissue, two groups were identified. The main group consisted of 120 patients, the comparison group comprised 90 patients. The severity of the menstrual pain syndrome was assessed using the three scales of the McGill Pain Questionnaire. For psychological testing was used a scale of self-assessment of anxiety of Ch.D. Spielberger – Yu.L. Khanina.

Results. In 90.9 ± 2.6% of patients of the main group the debut of a dysmenorrhea has taken place in the period of formation of menstrual function — within the first 2 years after menarche. The average value of the rank index of pain in the main group was higher than in the comparison group (3.5 ± 0.1 and 2.8 ± 0.1, p < 0.001). In an internal picture of perception of pain at patients of the main group the emotional component prevailed. Their psychoemotional status was distinguished by a higher level of the average score of reactive (45.3 ± 0.9 and 36.3 ± 1.4; p < 0.001) and personal (49.9 ± 0.6 and 41.4 ± 1.0; p < 0.001) of anxiety.

Conclusions. The obtained results give the grounds to consider the presence of clinical manifestations of an undifferentiated dysplasia of a connecting tissue in adolescent girls as a predictor, which is making heavier a clinical current of a menstrual pain syndrome.

Authors: Solomin Andrey V
Published: March 2018

The problems of improvement of modern types of transport and creation of new ones are important and topical for the human society development. One of the most promising and environmentally-friendly modes of transport is the high-speed maglev transport, moving at speeds of approximately 500 km/h. Objective. Justification of linear induction motor, development and research of various constructions of this type of motors. Methods. Description of linear induction motor with longitudinal and transverse magnetic flux for combined traction and lateral stabilisation system of maglev transport, having increased lateral stabilisation forces. The mathematical modelling of magnetomotive force (MF) in the air gap of traction linear motor of this type has been conducted. To analyse the MF the assumption has been made about even distribution of magnetic induction in the air gap in transverse direction and its sinusoidal longitudinal direction, making it possible to develop new mathematical model of MF distribution in the air gap of linear induction motor with longitudinal and transverse magnetic flux Results. The developed mathematical model for calculation of MF on traction linear machine will enable increasing accuracy of traction and lateral stabilisation combined system forces for maglev transport. The same relates to mutual location of inductor to the secondary element. All this proves the successful ten-year commercial operation experience of magnetically suspended train carrying passengers from an airport to Shanghai, P.R. China. The values of traction and lateral stabilisation forces of linear induction motor with longitudinal and transverse magnetic flux is greatly influenced by the character of current distribution in the secondary element. The character itself is influenced by MF distribution in the air gap.

Применение теории мотивационного комплекса трудовой деятельности к анализу организационного поведения преподавателей вуза
Authors: Литвинюк Александр Александрович , Жигун Леонид Александрович , Полевая Марина Владимировна , Камнева Елена Владимировна
Published: March 2018

В статье представлены результаты исследования особенностей организационного поведения преподавателей российских вузов впервые проведённого с использованием алгоритмов «Теории мотивационного комплекса трудовой деятельности» на основе межвузовского сотрудничества Российского экономического университета им. Г.В.Плеханова и Финансового университета при Правительстве РФ. Теория мотивационного комплекса - это относительно новая отечественная разработка в области мотивации, дающая возможность алгоритмизировать практическую деятельность в сфере проектирования эффективных систем мотивации и стимулирования труда.
В ее основу положена классификация мотивов трудового поведения, включающая в себя пять базовых групп, и анализ их взаимовлияния с учётом выделения трёх групп связей между ними: активирующее, угнетающее и противоугнетающее. Базовым понятием этой теории является мотивационный комплекс трудовой деятельности как целостная система взаимосвязей между пятью группами мотивов труда: мотивы приобретения; мотивы удовлетворения; мотивы безопасности; мотивы подчинения и мотивы энергосбережения. В качестве инструментария использован диагностическая методика «Мотивация», разработанная профессор Литвинюком А.А, и ее компьютерная версия, адаптированная к специфике трудовой деятельности профессорско-преподавательского состава российских университетов. Программное обеспечение было разработано на кафедре управления персоналом и психология Финансового университета при Правительстве РФ.
На основе полученных результатов впервые дан анализ текущих особенностей организационного поведения преподавателей вуза, возможные варианты его отклоняющихся вариантов, и прогноз его развития при отсутствии коррекций используемой системы мотивации труда. Основные исследования проведены на основе данных, полученных в результате опроса преподавателей Российского экономического университета им. Г.В.Плеханова. По итогам логического анализа полученных результатов разработаны и предложены к практическому применению рекомендации по совершенствованию системы мотивации и стимулирования трудовой деятельности профессорско-преподавательского состава российских вузов, дающие возможность ориентировать трудовое поведение преподавателей на цели и задачи, которые позволяют обеспечить повышение эффективности функционирования и развития российских университетов.

MiR-33a and statins collaboratively reduce the proliferative capacity of prostate cancer cells
Authors: Karataş Ömer Faruk , ITTMANN Michael
Published: March 2018

Objectives: Prostate cancer
(PCa) is one of the leading causes of cancer deaths among men in the developed
countries. Accumulating data suggests a high-cholesterol Western diet as an
important risk factor for PCa. Besides,significant evidencesassociate increased
serum cholesterol levels with PCa development and progression.In this study, we
aimed at investigating the collaborative roles of cholesterol analogs, cholesterol-lowering
drugs, and miR-33a, which is an important microRNA involved in regulation of
cholesterol metabolism,on the cellular phenotypes associated with PCa
progression. Methods: We evaluated the effects of low-density lipoprotein
(LDL) cholesterol, 25-hydroxycholesterol (25-HC), mevastatin
and simvastatin on their ownand together with miR-33a on the proliferation,
invasion and anchorage independent growthcapacity of PCa cells using Cell
Counting Kit-8, Matrigel invasion, and soft agar assays, respectively. Results:
We show that cholesterol analogs significantly promoted proliferative,
invasive, and clonogenic potential of PCa cells, while cholesterol
loweringstatins demonstrated opposite effects. Moreover, LDL and 25-HC reversed
the tumor suppressive potential of miR-33a and statin treatment promoted the
proliferation inhibitory effect of miR-33a on PCa cells. Conclusions: We
demonstrated that statins inhibited the cellular phenotypes associated with PCa
progression and miR-33a treatment strengthens the impacts of statins on
cellular proliferation. These findings suggest that statins alone and together
with miR-33a might be a useful tool for effective and successful eradication of
PCa cells.

Objective: Previous studies showed that
obstructive sleep apnea syndrome (OSAS) was associated with liver diseases such
as elevated liver enzyme levels and hepatic steatosis. The
aim of this study was to assess the relationship between serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels and
OSAS and its severity. Methods: A total of 617 patients who underwent PSG (polysomnography) between January 2016
and May 2017 were evaluated in this study. AST, ALT, total cholesterol,
triglyceride levels and body mass index were analyzed.
The data were analyzed using the Student t-test, ANOVA, Chi-square test, and Pearson's
correlation coefficient. Results: Five hundreds and thirty
patients with OSAS and 60 healthy controls were included in the study. Of the
patients in the OSAS group, 17.7% had an elevated ALT level and 7.9% had an
elevated AST level. There was a statistically significant difference in ALT and
AST levels between the OSAS and control groups (p < 0.001 and p < 0.001,
respectively). In the OSAS group, there was a statistically significant
positive relationship between serum ALT and AST levels and apnea-hypopnea index
(AHI), apnea index, oxygen desaturation index. Both AST and ALT levels were
statistically significantly higher in obese patients than in non-obese patients
(p < 0.001 and p < 0.001, respectively). ALT level
was statistically significantly higher in patients without hypertension than in
patients with hypertension (p < 0.001).
In OSAS patients without hypertension, there was a statistically significant
relationship between serum ALT and AST levels and AHI (r = 0.223, p < 0.001 and r = 0.142, p = 0.007; respectively). Conclusion:
OSAS is a risk factor for elevated liver enzyme
levels. Hypoxia plays an important role on liver enzymes in OSAS patients.

Lease Characteristics, Agency Costs, and Tax Considerations
Authors: Chen Kun-chih , Chi Wuchun , Lobo Gerald , Yong Kevin Ow
Published: March 2018

We examine the determinants that influence managers’ decision as to whether a lease is structured as a financing lease or an operating lease. Specifically, we find that firms with higher marginal tax rates, lower credit ratings, and more severe agency problems are more likely to use both operating leases and financing leases. However, tax considerations and debt capacity have little effect on which of the two types of lease is chosen. More importantly, we find that differences in kinds of agency problemsare reflected in the choice of the type of lease. Our study provides a better understanding of the extent of risks and benefits associated with the use of leased assetsand contributes to the discussion of impending revisions to lease accounting rules by standard-setting bodies.
