Published: June 2019

Abstract This research has been conducted with the aim of evaluating gender and age differences in attitudes of Serbian students toward Physical Education lessons and their preferences regarding lesson organisation. The sample of 542 students was divided into 4 subsamples: 140 female primary school pupils (13.51±0.41) and 129 male primary school pupils (13.47±0.33) from grade seven, and 134 secondary school female pupils (16.49±0.36) and 139 secondary school male pupils (16.44±0.37) from grade two. For the purpose of the research, the subjects voluntarily filled in two standardised questionnaires. ANOVA was used to determine significant differences in attitudes toward Physical Education lessons between pupils of different age and of different gender, while a Chi-square test was used to determine significant differences in pupils’ preferences regarding Physical Education lesson organisation. The results showed that primary school pupils had significantly more positive attitudes toward Physical Education lessons in relation to secondary school pupils, and that younger pupils prefer gender-based organisation of lessons which changes with respect to age and gender.

Uzorak od 542 učenika podijeljen je na 4 poduzorka: 140 učenica (13,51±0,41) i 129 učenika (13,47±0,33) sedmih razreda osnovnih škola, 134 učenice (16,49±0,36) i 139 učenika (16,44±0,37) drugih razreda srednjih škola. Kako bi se postigla svrha istraživanja, ispitanici su dobrovoljno popunili dva standardizirana upitnika. Za određivanje značajnosti razlika u stavovima prema nastavi Tjelesne kulture između učenika različitog uzrasta i različitoga spola koristila se ANOVA, a za ispitivanje značajnosti razlika u preferencijama učenika prema načinu organizacije nastave na satu Tjelesne kulture koristio se hi kvadrat test. Rezultati su pokazali da učenici osnovnih škola imaju značajno pozitivnije stavove prema nastavi Tjelesne kulture u odnosu na učenike srednjih škola i da mlađi učenici pokazuju više preferencija prema nastavi organiziranoj u spolno homogenim grupama, nasuprot starijim učenicima koji se radije opredjeljuju za rad u spolno mješovitim grupama. Zaključak ovog istraživanja jest da se stavovi srbijanskih učenika prema nastavi Tjelesne kulture i njihove preferencije prema načinu organizacije nastave na satu mijenjaju s uzrastom i u odnosu na pripadnost spolu.Ključne riječi: nastavni sat; osnovne i srednje škole; Srbija.
The Legal Role of Establishing the Origin of the Child in Legal Relations based on Inheritance when Assisted Reproductive Technologies are Applied
Authors: Aminova F. M. 
Published: June 2019

The author argues that it is necessary to amend the current legislation of the Republic of Tajikistan, namely, the procedure provided for registration of data regarding parents and child birth registration when the child is born as a result of application of assisted reproductive technologies after the death of the parent in order to make the child the participant of the relations based on inheritance. The author substantiates the conclusion that the child born after the death of the testator, after the distribution of hereditary property had taken place, will not be able to act as the participant of this hereditary relationship. However, being recognized as a legitimate child of the deceased parent, he or she will be entitled to participate in inheritance relations in future.The conclusion is made about ambiguity of the approach chosen by the Tajik law-maker depending on the branch of law to the category «child in the womb» when determining problematic aspects of defining of live birth and vitality of the child for the purpose of referring the child to the participants of hereditary legal relations.The author investigates the problems of including the child into the number of participants of hereditary legal relations in antiquity. A historical review is carried out, and separate categories of marriages created in the territory of historical Tajikistan for the purpose of the child birth in order to transfer inheritance are considered. The author has determined that Zoroastrian law allowed the child born from the deceased person prior to the conception of the child to participate in hereditary legal relations as if the child were native and would be born during the life of a «legal» father. There were no legal obstacles for a child born in this case preventing him or her from receiving inheritance The beginnings of «traditional» surrogacy motherhood in the territory of historical Tajikistan are determined.

A Mixed-Methods, Community-Based Study To Identify Predictors Of Depression In Latino Adolescents By Gender
Authors: Bigatti Silvia M. , Diaz Virna , Conrad Katrina K. , Ramirez Michelle , Weathers Tess D. 
Published: June 2019

Latino adolescent depressive symptoms are a growing problem, of interest to both the community and academic partner who are reporting the present study. In this mixed-method, community-based participatory research study we quantitatively examined predictors of depression known to impact adolescent mental health that are amenable to interventions. Concurrently, we qualitatively assessed parents’ perceptions of mental health problems in children, their causes and potential solutions. The data from parents (n = 108) was obtained in focus groups led in Spanish, and the data from adolescents (n = 86) was obtained in English language surveys. Among the adolescents there was an even representation of males (47.7%) and females (52.3%), Mage = 15.24 (SD = 1.97). Nearly half (47.7%) of the adolescents were experiencing minor depression and one in ten (10.5%) were experiencing major depression according to their scores on the PHQ-9. Adolescent participants reported low acculturative stress, average social support, and high mastery, as well as highly functional families. Males reported higher self-mastery than females and lower acculturative stress. Predictors of depression differed by gender. For males, self-mastery predicted depressive symptoms; for females acculturative stress predicted depressive symptoms. The focus groups with parents supported and expanded quantitative findings. The parents demonstrated a keen awareness of depression in teens and their own contributions to the problem, including their efforts to maintain their culture of origin which prevents integration of their children into the majority culture. Parents also reported difficulties knowing what steps to take and finding resources. The additional dimension of parental voice is often missing from studies of adolescents, and here it clarified many of the issues identified in the teens. These findings suggest the need to focus on mental health in this population, potentially developing differential interventions by gender and taking a family systems approach.

In an effort to realize the development of new economic growth centers in undeveloped areas, determining superior products is very important. Furthermore, by encouraging the development of the specific potential of underdeveloped regions, it is expected to be able to encourage and accelerate economic growth and improve community welfare. so that this builds a new center for economic growth. In general, the flagship program of each district is used as leverage in stimulating regions for development. Notably, there are six parameters left behind. These include the community economy, human resources, infrastructure (infrastructure), local financial capacity (fiscal gap), accessibility, and regional characteristics. It is expected that poverty alleviation and unemployment reduction can be achieved through an increase in the local financial capacity through optimization of the potential of local products. The development of district superior product programs in growth node will be beneficial in encouraging the economic growth of the community.
Main Findings: The results of this study shortlisted some superior agricultural products in the regency with a corn LQ value of 3.86, 4.28 rice; chili 2.37; and cassava 3.92. The coconut plantation 1.89; betel 1.59 and sugar cane 3.31. For the livestock sector, the LQ of Cattle was 3.91; Goat 3.02 and free-range chicken 2.98. From the results of the discussion and in-depth analysis, the flagship products of Bondowoso district were rice, sugar cane, cattle and corn.
Implications/Applications: The present research is expected to establish local products that represent regional superior commodities and can be produced to improve the economy of the community. Such development will also provide job opportunities for the local communities and reduce the rate of poverty.

Properties, Characteristics and Parameters of Permanent Magnet Synchronous Motors under Vector and Scalar Frequency Control
Authors: Firago B. I. , Aleksandrovsky S. V. 
Published: June 2019

In order to improve energy performance and simplify the system of frequency control of the speed of electric drives, the area of application of synchronous frequency-controlled electric drives with both dependent and independent frequency setting of the voltage supplying the engine is being expanded. This is due to the fact that, as compared with asynchronous variable frequency drives, synchronous ones undergo lower power losses and they have rigid mechanical characteristics without speed feedback. Also, the simplest law of frequency control, viz. a proportional one, which, however, provides the maximum electromagnetic torque of the engine unchanged at R1 = 0 at all frequencies due to the constant magnetic flux, is applicable to a synchronous frequency controlled motor. Characteristics and properties of permanent magnet synchronous motors (PMSM) with the dependent frequency setting of supplied voltage (under vector control of PMSM) have been discussed and reviewed in technical literature quite sufficiently. It cannot be said about the PMSM with independent frequency setting reference which work under scalar frequency control. In the present article a comparison of properties and characteristics of vector and scalar frequency controlled PMSM is presented. For a scalar frequency controlled PMSM a function of the relative voltage g on the relative frequency a (g = f(a)) taking into account the PMSM parameters has been defined. The derived function g = f(a) differs from a proportional law of frequency control g = a. It is found that the influence of the parameters on the law of frequency control is small, and it can be applied without adjustment in most cases, in contrast to the frequency control of the asynchronous motor. For scalar frequency control, a method for determining the parameters of synchronous motors has been proposed in accordance with the parameters of synchronous motors with permanent magnets, which are given for operation under vector control. According to the presented methodology the OMRON SGMH-50D engine parameters have been determined for scalar frequency control and the function of g = f(a) have been computed.

Abstract
To assess the effects of the combination of DAPT and oxaliplatin on the biological behavior of human ovarian cancer stem cells. In vitro cultured human ovarian cancer stem cells were randomly divided into DAPT, L-OHP, DAPT + L-OHP, and control groups. MTT assays were measured to assess the ability of inhibit proliferation. Inverted microscopy, flow cytometry, and in vitro invasion assays were performed to assess cell morphology, apoptosis, and cell invasion, respectively. Then, western blotting was used to detect Notch-1 and LRP1 expression in the four groups of cells. MTT assay revealed that DAPT and L-OHP monotherapy could inhibit the proliferation of ovarian cancer stem cells in a time- and dose-dependent manner. Inverted microscopy showed that untreated ovarian cancer stem cells had an oval or polygonal morphology, with a plump shape and large nuclei. After treatment with DAPT or L-OHP, cells shrank and cracked, with an irregular shape and increased shedding. Flow cytometry revealed that apoptosis was significantly higher in the DAPT and L-OHP groups compared with the control group; the DAPT + L-OHP group had a significantly higher rate of apoptosis than either the DAPT or L-OHP groups. An in vitro invasion assay revealed that DAPT + L-OHP inhibited cell invasion to a greater extent than either DAPT or L-OHP alone. Western blotting revealed that, compared with control, L-OHP had no effect on Notch-1 protein expression, whereas DAPT and DAPT + L-OHP significantly reduced Notch1 protein levels. In addition, cells treated with DAPT + L-OHP expressed much less Notch than those treated with DAPT alone. In the L-OHP group, LRP protein levels were increased significantly, whereas levels were decreased significantly in the DAPT and DAPT + L-OHP groups. DAPT inhibits the proliferation of ovarian cancer stem cells, promotes their apoptosis, weakens their invasive ability, and functions synergistically with L-OHP.

Abstract
Background: The occurrence of a mediastinal germ cell tumor (GCT) and hematological malignancy in the same patient is very rare. Due to its rarity, there have been only two reports of the concurrent cases undergoing detailed genetic analysis with whole-exome sequencing (WES), and the possible clonal relationship between the both tumors remained not fully elucidated.
Methods: We performed whole-exome sequencing analysis of mediastinal GCT and acute myeloid leukemia (AML) samples obtained from one young male adult patient with concurrent both tumors, and investigated the possible clonal relationship between them.
Results: 16 somatic mutations were detected in the mediastinal GCT sample and 18 somatic mutations in the AML sample. Mutations in nine genes, including TP53 and PTEN both known as tumor suppressor genes, were shared in both tumors.
Conclusions: All in our case and in the previous two cases with concurrent mediastinal GCT and AML undergoing with whole-exome sequencing analysis, TP53 and PTEN mutations were commonly shared in both tumors. These data not only suggest that these tumors share a common founding clone, but also indicate that associated mediastinal GCT and AML harboring TP53 and PTEN mutations represent a unique biological entity.

Abstract
Background

Breast cancer (BRCA) is one of the most common malignancies in women. To reveal the molecular mechanism of the BRCA, the core genes associated with BRCA was studied by the integrated bioinformatics methods in the current study.

Results

A total of 1181 DEGs, 84 DEGs, and 190 DEGs were detected in GSE7904, GSE10797, and GSE103512, respectively. In addition, 7 hub genes overlapped from 3 datasets were selected, and ANNXA1, MYH11, IGFBP6, FOS, FOSB, KIT, and WLS might be the core genes of BRCA. The Go function analysis showed that the DEGs were enriched in chromosome segregation, gland development, leukocyte migration, extracellular structure organization and so on. The KEGG pathway analysis showed that the most DEGs were enriched in Pathways in cancer, Focal adhesion, ECM-receptor interaction, PPAR signaling pathway, etc. Additionally, ANXA1 was associated with worse overall survival, and the other 6 hub genes were associated with better overall survival.

Conclusions

ANNXA1, MYH11, IGFBP6, FOS, FOSB, KIT, and WLS might be the core genes of BRCA. WLS, IGFBP6, and FOSB might be a new biomarker of the breast tumor and potential new drug targets. This study provided new evidence for the future genomic individualized treatment of BRCA.
Efficacy of intranasal dexmedetomidine for removal of inhaled foreign bodies in children by flexible fiberoptic bronchoscopy: a randomized, double-blind, placebo-controlled clinical trial
Authors: Bi Yanmei , Ma Yushan , Ni Juan , Wu Lan 
Published: June 2019

Abstract
Background: The traditional technique for foreign body removal is rigid bronchoscopy. However, fiberoptic bronchoscopy is becoming more popular for foreign body removal. Compared with rigid bronchoscopy, fiberoptic bronchoscopy is better suited for removing foreign bodies from the distal airways and upper lobe bronchi because of the smaller diameter and greater flexibility of the bronchoscope. Dexmedetomidine, a highly selective α2 adrenergic agonist, reduces preoperative anxiety, reduces the requirement for general anesthetics, and does not induce respiratory depression. The safety and efficacy of intravenous dexmedetomidine have been confirmed in patients undergoing fiberoptic bronchoscopy. Intranasal dexmedetomidine reportedly produce satisfactory sedation in children. We hypothesized that intranasal dexmedetomidine at 1 µg·kg−1 administered 25 minutes before anesthetic induction can reduce the incidence of adverse events during fiberoptic bronchoscopy under sevoflurane inhalation general anesthesia.
Methods: Forty preschool-aged children (6–48 months) with an American Society of Anesthesiologists physical status of I or II were randomly allocated to receive either intranasal dexmedetomidine at 1 µg·kg−1 or normal saline at 0.01 ml·kg−1 25 minutes before anesthetic induction. The primary outcome was the incidence of perioperative adverse events. The heart rate, respiratory rate, separation score, tolerance of the anesthetic mask, agitation score, anesthetic induction time, consumption of sevoflurane, and recovery time were also recorded.
Results: The incidence of laryngospasm, breath-holding, and coughing were significantly lower in patients who received intranasal dexmedetomidine than saline (15% vs. 50%, P=0.018; 10% vs. 40%, P=0.028; and 5% vs. 30%, P=0.037, respectively). Patients who received intranasal dexmedetomidine had a lower separation score (P=0.017), more satisfactory tolerance of the anesthetic mask (P=0.027), a significantly shorter anesthetic induction time (5.75±1.4 vs. 7.75±2.5 min, P=0.004), and less consumption of sevoflurane (38.18±14.95 vs. 48.03±14.45 ml, P=0.041). The recovery time was similar in both groups, and the frequency of postoperative agitation was significantly lower in patients who received intranasal dexmedetomidine (P=0.004).
Conclusions: Intranasal dexmedetomidine at 1 µg·kg−1 can reduce the incidence of laryngospasm, breath-holding, and coughing during fiberoptic bronchoscopy for foreign body removal via its sedative and analgesic effects. Moreover, intranasal dexmedetomidine can reduce postoperative agitation without a prolonged recovery time.
