The purpose of this study was to determine pedagogical conditions for effective swimming training of students of pedagogical educational institutions.Materials and methods. The experimental group (EG) consisted of 45 first-year female students of the schools of foreign philology, physics and mathematics education, natural geography and ecology (special medical group) who had a sufficient physical fitness level and could not swim. The control group (CG) was composed of 40 first-year female students of the schools of foreign philology, physics and mathematics education, natural geography and ecology (special medical group) who had a sufficient physical fitness level, could float, swim short distances (3-5 meters).Results.After the experiment, there was a significant improvement in the test results. Specifically, the experimental group students showed increasein all parameters of the cardiorespiratory system functional state – an increase in breath-holding time in the Stange’s test and the Genci’s test (р= 0.001) and, accordingly, in the Harvard step test (р = 0.001). The results of the experimental group students improved in the Harvard step test by 13.56%; in the Stange’s test – by 9.26%; in the Genci’s test – by 13.15% (р= 0.001).The experimental group students showed a statistically significant improvement in the test results of physical fitness. Specifically, in the tests: “Standing long jump”, the result increased by 4.70%; “Sit-ups in 30 seconds” – by 10.59%; “Jumping rope” – by 6.91%; “Push-ups” – by 17.62% (p= 0.001).Conclusions.The study revealed a statistically significant effectiveness of the suggested methods of teaching swimming to special medical group students. On the basis of discriminant analysis, the researchers ascertained a statistically significant influence of the experimental methods on the dynamics of the students’ physical and functional fitness. Positive dynamics of change was found in the indicators of high level of anxiety during swimming training.
Percept of Teachers Regarding Integration of Education for Environment and Sustainable Development in Primary Schools
Authors: Pehoiu Gica 
Published: June 2019

Environmental education studies emphasize the importance of this type of education since small ages as a basis for developing appropriate attitudes and behaviour towards the long-term environment, increasing accountability and motivation to take action to protect the environment. Geography has an essential role in environmental education, given the interdisciplinary character of this science, which aims at the interaction between man and environment, so that many studies are devoted to how this discipline contributes to forming of this type of education. The present paper focuses on applying a questionnaire among teachers, they being discipline holders of some schools in Dâmboviţa County (Romania), to highlight their perceptions, with the main reference to the concept of environmental education in primary school. Perceptual studies will therefore be useful in understanding the importance that respondents place on these issues, how the concepts of environmental education and sustainable development are focused to students, methods and techniques used predominantly in the undertaken activities.

The aim of the research was to compare the results of the thermal decomposition of organic matter using different research methods. Experiments were carried out to assess interpretation methods in the characterization of the generation potential of source rocks. The research was conducted for samples of Menilite shales, recognized on the basis of long-term geochemical studies as good quality source rocks. The samples represented the Menilite Beds of the Silesian Unit, taken from the outcrops in the Carpathians. Research using known methods: Rock-Eval pyrolysis (RE), thermogravimetric and calorimetric methods (TG/DSC), and pyrolysis methods combined with gas chromatography analysis (PY-GC), were performed on the same samples- both on rock samples, as well as isolated kerogen. Such integrated studies have so far not been conducted on any rock material. The applied research methods showed a significant comparability of the results obtained. A number of correlations were found between the parameters from individual methods, including: the amount of hydrocarbons separated during PY-GC in the temperature range of 300–650°C, and the parameter S2 from RE, and mass loss in the TG analysis in the same temperature range; S2 values of rock samples and kerogen with weight loss as a result of pyrolysis from TG/DSC analysis at temperatures in the range of 300–650°C; temperature values of the maximum peak S2 (Tpk2) of rock samples with the maximum mass loss temperature during TG analysis; residual carbon content (RC) from RE analysis of rock and kerogen samples with a mass loss as a result of burning residual organic matter from TG/DSC analysis at temperatures in the range of 650–1050°C. The mass loss determined during thermogravimetric analysis, combined with the percentage share of individual hydrocarbon fractions, in which the C9+ fraction is significant, confirms the high petroleum potential of the organic substance contained in the Menilite Beds. Comparative studies of pyrolytic methods: Rock Eval, TG/DSC and PY-GC have proved the compatibility of the results obtained with all methods. Each of the methods also makes it possible to obtain mutually complementary information relating to the TOC, the degree of thermal maturity and type of generated hydrocarbons and other non-hydrocarbon compounds. The conducted tests and performed correlations showed the usefulness of a set of thermal methods to obtain complete information on source rocks.

Comparative Histological Study of the Stomach in Two Species of Iraqi Vertebrates (Magpie Pica pica L. and Small Asian Mongoose Herpestes javanicus E.)
Authors: Et al. AL –Nakeeb 
Published: June 2019

A histological study showed the wall of the stomach in Pica pica and Herpestes javanicus consists of four layers: mucosa, submucosa, muscularis externa and serosa. Also, the present study showed many differences in the histological structures of the stomach for each in both types. The stomach of P. pica consists of two portions: the proventiculus and gizzard, while the stomach of H. javanicus consists of three portions: cardiac, fundic and pyloric regions. The mucosa layer formed short gastric folds, named plicae. In the proventiculus of P. pica, sulcus is found between each two plicae, but the folds called gastric pits in the gizzard, which are full with koilin. Lamina properia in both types contained gastric glands (straight simple tubular glands) named superficial glands, as well as another gastric gland found in the submucosa layer of the proventiculus in P. pica only named deep gastric glands. The gastric gland in the stomach of H. javanicus contained: mucous neck cells and parietal cells positive to AB/PAS stains in cardiac portion, as well as chief cells in fundic portion, but pyloric portion had just mucous neck cells. Muscularis externa in both types formed two muscle layers: inner and outer layer.

Authors: Et al. Ghaidan 
Published: June 2019

In the present study, the effects of brake pad particles of lung and liver histological sections were evaluated for (60) adult male mice. The animals were divided into three groups ( A,B,C) according to the periods of exposure (4, 8, and 12) weeks respectively exposed to brake pad particles in addition to the control groups (F) exposed to fresh air only. A special inhalation chamber designed locally has been used to expose the animals. The exposure to brake pad particles was (2.228) µg/m³ for 30 min/day, 5 days/week for (4,8and12) weeks respectively.
The examination in group (A) of the histological sections of the lung showed the thickness of interalveolar septa. Also, a congestion of alveolar capillary was marked indicating pulmonary emphysema. The infiltration of alveolar macrophages showed the engulfed foreign particles (pad particles) within their cytoplasm, and peribronchial fibrosis. Group (B) showed the presence of pad particles (anthracosis), whereas the bronchial tree showed bronchitis with the bronchus-hyperplasia of mucin-producing cells (epithelial hyperplasia). Still another section showed an infiltration of mononuclear leukocytes and focal lobar necrosis. The third group (C), in turn, revealed acute interstitial bronchopneumonia with peribronchial focal necrosis and mild pulmonary edema with alveolar anthracosis.
As regards the liver, group (A) showed mild central venous congestion. Group (B), on the other hand, gave acute hepatitis, congestion of the central vein hyaline degeneration and mitotic figure having 2-3 nuclei. Severe congestion of the central vein with vascular amyloid deposition and most of the hepatocytes revealed coagulate necrosis in group (C). These changing tissues increased with increasing the exposure periods and were clearer in group (C) which was exposed for 12 weeks.
The continuous exposure to brake pad particles lead to damaging important body organs tissues and effect on human health, these particles can be considered as a type of pollutants added to air pollutants in different cities of Iraq.

Published: June 2019

Abstract
Background

Obesity has became a global health issue. The previous studies suggested that acupoint catgut embedding (ACE) might be a potential treatment option for obesity. In this study, we will conduct a rigorous and normative trial to determine the efficacy of ACE for obesity.

Methods/design

A total of 99 eligble patients diagnosed with obesity will be recruited. They will be randomly allocated to either the verum ACE group, sham ACE group or waiting-list group with 33 patients in each group. Each patient in two ACE groups will recieve 8 sessions of treatment over 8 weeks. The primary outcomes will be the reduction of body mass index after treatments. Secondary outcomes will include waist circumference, hip circumference, waist hip rate, body fat percentage, blood lipid level, as well as the subcutaneous fat area, visceral fat area and the scale assessments of World Health Organization Quality of Life. All outcomes will be evaluated at baseline, end of 8 weeks treatments and 3-month follow up. The evaluators and data analysts will be blinded to group allocation.

Discussion

The finding of this randomized, sham- and waiting-list-controlled trial will help to investigate the influence of ACE on clinical variables as well as visceral fat area, which will provide high-quality evidence on the efficacy of ACE for treatment of obesity.

Published: June 2019

Abstract
Different variants of blaNDM has been reported across Indian subcontinent within diverse host range of gram negative bacilli. Most of their transferability depends on types of plasmid that encodes resistance determinant. IncX type plasmid is more recently known for carrying carbapenem resistance and NDM-4 variant is considered to have better hydrolytic property. This study aims to investigate the maintenance and stability of blaNDM-4 within BHR and transcriptional response. E.coli of clinical origin that harbor blaNDM-4 within IncX3 plasmid were used. Six different hosts were selected for gene transfer experiment, two strains of E.coli, K.pneumoniae, P.mirabilis, A.baumannii and P.aeruginosa. All the transformants and parent isolate were subjected for stability within new host. IncX3 plasmid encoding blaNDM-4 was transferred in host when imipenem (0.5µg/ml) screen agar was used for selection of transformants which are coharbouring resistance for aminoglycosides and quinolone. Plasmid was successfully expanded within all the six recipients till 55th serial passages. Transcriptional expression with NDM gene was variable for parent isolates though for new hosts it was showing random increased pattern in Proteus, E.coli, and DH5α. This could highlight, external carbapenem pressure helps in maintenance and expression of blaNDM-4 within different host range and epidemiological significance and will help in tracking the genetic vehicle responsible for their transmission,restricting their spread.
Meta-analysis of the endothelial protein C receptor rs867186 genotype in malaria

Published: June 2019

Abstract
The interaction between the P. falciparum erythrocyte membrane protein 1 (PfEMP1) on the surface of parasitized red blood cells (pRBC) and the endothelial cells (EC) receptors during P. falciparum infection results in the sequestration of pRBC from blood circulation. The amount of sequestration is determined by specific interactions among PfEMP1 and several host adhesion receptors, including intercellular adhesion molecule 1 (ICAM-1), CD36, and endothelial protein C receptor (EPCR). PfEMP1 is composed of multiple domains such as the cysteine-rich inter domain region (CIDR) and Duffy binding –like (DBL) domains. CIDRα1 competitively binds to EPCR with activated protein C (APC) and impair cytoprotective and anticoagulant effects by APC, which plays an important role in severe malaria (SM) pathogenesis such as cerebral malaria (CM) and severe malaria anemia (SMA). The strategy to inhibit EPCR binding to pRBC while to concomitantly strengthen its binding to APC may be crucial in restoring impaired protein C (PC) system’s function. The purpose of this study is to evaluate the association between severity of malaria and the EPCR genotypes as well as the soluble EPCR (sEPCR), and the study also addresses the physiological relevance of EPCR genetic polymorphism. In this study, we conducted meta-analysis on the eligible studies by comparing the frequency of EPCR rs867186-GG versus rs867186- GA and -AA genotype in SM, mild malaria (MM) or uncomplicated malaria (UM) patients and healthy individuals from Thailand, Uganda, Benin, Tanzania, and Ghana. We also determined the relationship between rs867186 genotype and sEPCR levels. Our results showed that the gene type of rs867186-GG is higher in MM/UM than in SM patients. SM patients carrying the rs867186-GG genotype have higher plasma soluble EPCR (sEPCR) levels than in rs867186-AG and rs867186-AA carriers. A significant difference is seen with the higher plasma sEPCR expression among MM/UM patients carrying the rs867186-AG genotype compared to those carrying rs867186-AA. Similarly, the rs867186-GG is associated with sEPCR level in healthy individuals. In conclusion, this meta-analysis demonstrates that pRBCs and EPCR interactions are associated with malaria severity, and treatments that block pRBC binding to EPCR via PfEMP1 CIDRα1 could be a potential therapy for SM.

ABSTRACTApomictic grasses predominate among tropical forages, and specific breeding techniques are needed for their genetic improvement. The objectives of this study were (i) to generate hybrids by crossing tetraploid sexual and apomictic Paspalum simplex Morong genotypes, (ii) to develop a technique based on molecular markers for early identification of apomictic hybrids, and (iii) to determine the relationship between mode of reproduction and performance of hybrids. Crosses were made between two induced sexual and seven apomictic tetraploid plants. Identification of apomictic hybrids during seedling stage was performed using a marker linked to apomixis, and by flow cytometric seed analysis. Hybrids were evaluated under field conditions for plant diameter and height, initial growth, and seasonal regrowth during two consecutive growing seasons. Sexual tetraploid plants used as female parents behaved as allogamous, since 95% of the progeny had male‐specific markers. The ratio between apomictic and sexual hybrids differed from 1:8.7 to 1:0.6 among crosses, with a mean of 1:2.4. There was a 96% coincidence between the use of the apomixis‐linked marker and flow cytometric seed analysis. A technique based on the use of early DNA isolation and the amplification of a molecular marker linked to apomixis was developed. We found no overall difference between apomictic and sexual hybrids for the evaluated traits, except for fall regrowth in the first year, for which apomictic hybrids were superior. Generation of large tetraploid hybrid progenies is possible in P. simplex. Segregation for mode of reproduction depends on parents involved. Agronomic performance is not related to reproductive mode among tetraploid hybrids.

Published: June 2019

Abstract
In this work, a series of polyetherimide (PEI) flat sheet membranes were produced with different concentrations of polyvinylpyrrolidone (PVP) addition via the phase inversion method. The effects of additions on membrane morphology and performance were investigated. Synthesized membrane had the properties of ultrafiltration membrane. Although PEI is not widely used for water treatment, in this study, the ferrous iron removal rate was investigated and good results were obtained. Through the membrane production experiments, the PEI content was 22 wt%. PVP was added as a pore-forming agent with concentrations of 2, 4 and 8 wt%. N-methyl-2-pyrrolidone (NMP) was used as solvent. Distilled water was used for the coagulation bath. After production, all membranes were characterized by using contact angle, permeability, porosity, and scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FT/IR) analyses. With the increasing doses of PVP addition, the permeability of the PEI membranes produced in this study increased, while porosity results were changeable. The permeability was 23 L/m2h bar for the membrane with 2 wt% PVP content, while the permeability for the membrane with 8 wt% PVP content was 32 L/m2h bar. Contact angles increased with PVP addition to PEI membranes. With the increasing PVP concentration, the finger-like pores and the pores located in the sub-layer expanded.
Assessment of the adsorption kinetics, equilibrium and thermodynamic for Pb(II) removal using a hybrid adsorbent, eggshell and sericite, in aqueous solution
Authors: Choi Hee-Jeong 
Published: June 2019

AbstractHybrid adsorbents (ES) were prepared with mixing of eggshell and sericite as binders, and Pb(II) was removed from aqueous solutions. Sericite has the advantage of not only serving as a binder for hybrid adsorbent but also having a negative charge on the surface to improve the removal efficiency of heavy metals. Various parameters affecting the removal of Pb(II) from aqueous solutions were investigated using the optimal conditions derived. In addition, adsorption kinetics, adsorption isotherms and thermodynamic analyses were performed using the experimental results of each parameter. The ES had a more specific surface area and porosity than sericite or eggshell and contained a large number of OH groups favoring heavy metal adsorption. As a result of the adsorption of Pb(II) using the ES, the adsorption process was physical and suitable for the Freundlich isotherm. In addition, the adsorption process of Pb(II) by the ES was a spontaneous endothermic reaction. The ES can quickly reach the adsorption equilibrium and strong adsorption strength. In addition, the CaOH contained in the ES can neutralize the pH of wastewater, and it is possible to treat heavy metal ions in industrial wastewater and acid mine wastewater without controlling the pH. ES adsorbents using waste eggshells are very economic because they recycle what would otherwise be waste and have great significance in terms of resource reuse.
