Polymer-Assisted Modification of Metal-Organic Framework MIL-96 (Al): Influence on Particle Size, Crystal Morphology and Perfluorooctanoic Acid (PFOA) Removal
Authors: Hakim Mohd Azmi Luqman , Williams Daryl R. , Ladewig Bradley P.
Published: May 2020

AbstractA new synthesis method was developed to prepare an aluminum-based metal organic framework (MIL-96) with a larger particle size and different crystal habits. A low cost and water-soluble polymer, hydrolyzed polyacrylamide (HPAM), was added in varying quantities into the synthesis reaction to achieve >200% particle size enlargement with controlled crystal morphology. The modified adsorbent, MIL-96-RHPAM2, was systematically characterized by SEM, XRD, FTIR, BET and TGA-MS. Using activated carbon (AC) as a reference adsorbent, the effectiveness of MIL-96-RHPAM2 for perfluorooctanoic acid (PFOA) removal from water was examined. The study confirms stable morphology of hydrated MIL-96-RHPAM2 particles as well as a superior PFOA adsorption capacity (340 mg/g) despite its lower surface area, relative to standard MIL-96. MIL-96-RHPAM2 suffers from slow adsorption kinetics as the modification significantly blocks pore access. The strong adsorption of PFOA by MIL-96-RHPAM2 was associated with the formation of electrostatic bonds between the anionic carboxylate of PFOA and the amine functionality present in the HPAM backbone. Thus, the strongly held PFOA molecules in the pores of MIL-96-RHPAM2 were not easily desorbed even after eluted with a high ionic strength solvent (500 mM NaCl). Nevertheless, this simple HPAM addition strategy can still chart promising pathways to impart judicious control over adsorbent particle size and crystal shapes while the introduction of amine functionality onto the surface chemistry is simultaneously useful for enhanced PFOA removal from contaminated aqueous systems.

Understanding the mechanism of catalytic hydrogenation at the local environment requires chemical and topographic information involving catalytic sites, active hydrogen species and their spatial distribution. Here, tip-enhanced Raman spectroscopy (TERS) was employed to study the catalytic hydrogenation of chloro-nitrobenzenethiol on a well-defined Pd(sub-monolayer)/Au(111) bimetallic catalyst (pH2=1.5 bar, 298 K), where the surface topography and chemical fingerprint information were simultaneously mapped with nanoscale resolution (≈10 nm). TERS imaging of the surface after catalytic hydrogenation confirms that the reaction occurs beyond the location of Pd sites. The results demonstrate that hydrogen spillover accelerates hydrogenation at the Au sites within 20 nm from the bimetallic Pd/Au boundary. Density functional theory was used to elucidate the thermodynamics of interfacial hydrogen transfer. We demonstrate that TERS as a powerful analytical tool provides a unique approach to spatially investigate the local structure-reactivity relationship in catalysis.

Published: May 2020

Mitochondrial respiratory complex II (CII), also known as succinate dehydrogenase, plays a critical role in mitochondrial metabolism. Known but low potency CII inhibitors are selectively cytotoxic to cancer cells including the benzothiadiazine-based anti-hypoglycemic diazoxide. Herein, we study the structure-activity relationship of benzothiadiazine derivatives for CII inhibition for the first time. A number of more potent derivatives were identified. Cytotoxicity evaluation of the novel derivatives resulted in the identification of compounds with greater anticancer effect than the parent; two benzothiadiazine derivative classes (24a-d and 30a, 30c, 30d) that possess activity to reduce the cell viability of 22Rv1 prostate cancer cells and five novel 7-fluorobenzothiadiazine derivatives which possessed significant cytotoxicity in a cellular model of triple negative breast cancer. No correlation between cytotoxicity and CII inhibition was found, indicating an as yet undefined mechanism of action of this scaffold.
Target blood pressure levels in patients with arterial hypertension and frailty
Authors: Ostroumova Olga D , Cherniaeva Marina S , Morozov Alexandr P
Published: May 2020

Arterial hypertension (AH) is an important public health problem worldwide. The high prevalence of hypertension can partially be explained by an increase in blood pressure (BP) with age and a rapid increase in the elderly population (over 65 years old). Despite the effect of age on BP, evidence of target blood pressure values for its control in patients of older age groups with AH is limited, especially if they have frailty. There are data from a number of studies that reveal a relationship between lower BP levels and all-cause mortality in patients with AH in older age groups. In clinical practice, decisions regarding BP targets are especially difficult in elderly people with frailty who often do not meet the criteria for inclusion in randomized controlled trials and for this group of elderly people the clinical recommendations of leading communities do not give a specific answer about the target BP level. The evidence base regarding the target BP values in the treatment of AH in patients of older age groups with frailty presented in this review is not numerous, but its analysis suggests the advantages of higher BP numbers, with maximum systolic BP values of 165 mm Hg and diastolic BP of 90 mm Hg, while lower BP levels may be unsafe in terms of increasing the risk of adverse cardiovascular events and mortality from both cardiovascular causes and all causes. Polymorbidity in combination with polypharmacy and an increased risk of adverse events require a patient-oriented individual approach to the appointment of antihypertensive therapy. For a final decision on the management tactics of patients with AH and frailty, large, specially designed randomized clinical trials are needed.

Published: May 2020

Abstrak. Pengalaman-pengalaman yang terjadi dalam kehidupan tidak semuanya merupakan pengalaman yang menyenangkan. Setiap pengalaman melibatkan perasaan. Pengalaman positif melibatkan perasaan positif dan pengalaman negatif melibatkan perasaan negatif pula. Mengalami kekerasan seksual bagi perempuan merupakan pengalaman negatif yang sangat menyakitkan dan berdampak buruk pada kondisi psikologis. Seksualitas merupakan sesuatu yang kompleks dan sensitif yang tidak hanya menyangkut aspek biologis saja namun juga aspek psikologis dan juga sosial. Oleh sebab itu korban kekerasan seksual sangat mungkin mengalami gejala klinis akibat dari hal buruk yang dialaminya. Gejala klinis yang mungkin dialami adalah kecemasan.  Penanganan dan penyembuhan kecemasan yang menjadi tanda terjadinya trauma psikis akibat kekerasan seksual haruslah mendapat perhatian besar agar dampak kekerasan seksual pada koran tidak semakin menjadi parah dan merusak kualitas hidup korban. ACT membantu untuk tetap menemukan kebahagiaan di tengah situasi yang tidak menyenangkan karena pengalaman negatif yang dialami dengan cara menerimanya. ACT mampu meningkatkan fleksibilitas psikologis. Semakin fleksibel seseorang maka semakin mudah menyesuaikan diri dengan kondisi karena memiliki kemampuan yang baik untuk menerima sehingga semakin mudah pula untuk bertindak menuju nilai yang ingin dicapai. ACT diharapkan dapat menurunkan kecemasan yang merupakan dampak yang dialami oleh perempuan korban kekerasan seksual. Dengan ACT, diharap akan terjadi peningkatan fleksibilitas psikologis yang dapat menurunkan kecemasan  yang dialami korban kekerasan seksual.

Guided by the theory of language transfer, this paper examines the transfer of English (second language) in the early stages of the acquisition of German (third language) by Chinese English majors. The results reveal that English has both positive and negative effects on German acquisition, especially on German pronunciation, vocabulary and sentence learning. On the basis of these findings, some suggestions are also put forward in order to improve the efficiency of third language (German) teaching, namely, English-as-a-vehicular-language teaching, contrastive teaching and corpus-based teaching.
On the Ancient Educational Thought under the Opposite View of Human Nature of the Pre-Qin Scholars—— On its Value to Contemporary Higher Education
Authors: Zhao Zhichao
Published: May 2020

The pre-qin Scholars’ views on human nature could be divided into two types: malleable human nature and immalleable human nature. Based on the theory of the malleability of human nature, Confucianism formed an educational concept aiming at shaping the ideal personality of Confucianism. The theory of immutability of human nature has become the root of the two distinct educational concepts of Taoism, which advocates letting nature take its course, and Taoism, which aims at reforming human behavior. Either idea has its reasonableness. All of these have a very important impact on our higher education today.

Published: May 2020

Any material can be considered a composite consisting of grains of different orientations which possess different properties depending on the history of their reorientation upon thermomechanical processing. A well-known selective character of X-ray methods is attributed to the fact that only grains of certain orientations participate in the formation of reflected radiation. A comprehensive description of the material including information about the substructure of grains of all orientations necessitates developing of the method providing description of the substructural state of grains located in the volume under study by analyzing the profile of x-ray lines. The proposed x-ray diffractometric method of Generalized Direct Pole Figures (GPF) which suggests combination of texture imaging and recording the profile of x-ray lines appeared to be rather efficient in a systematic x-ray study of the substructural heterogeneity of textured metallic materials. The measured parameters of the X-ray line profile — the true angular half-width β and angular peak position 2θ — are determined by the distortion (fragmentation) of the reflecting grains and interplanar spacings in their crystal lattice, respectively. The method provides a possibility to compare the substructure features of grains with different crystallographic orientations. An algorithm for calculation of the true physical half-width of the x-ray line using the necessary computer programs is presented. GPF β and GPF 2θ are presented for metal materials with hcp, fcc, and bcc crystalline lattices, as well as characteristic diagrams of their mutual correlation with texture PF. The use of the developed GPF method makes it possible to identify patterns of the formation of substructural heterogeneity during plastic deformation of metals.
Determination of the iridium micro-concentrations using a kinetic catalytic method
Authors: Khomutova E. G. , Levkevich E. A.
Published: May 2020

The catalytic effect of iridium on the oxidation of water-soluble porphyrin — 5,10,15,20-tetrakis (4-sulfonatophenyl) porphin (TSPP) with sodium periodate is studied for the first time. A method for determination of the iridium micro-content by the catalytic effect of iridium on the oxidation of water-soluble porphyrin 5,10,15,20-tetrakis (4-sulfonatophenyl) porphin with sodium periodate in a flow-injection system is developed. The lower limit of the determined iridium concentrations is 0.2 × 10–5 μg/ml (P = 0.95), which is lower than that for the methods described in the literature. Optimal conditions for determination have been specified: pH 3; concentration of the reagents in the flows of a given hydraulic mixing scheme 0.5 × 10–5 M TSPP and 0.15 M NaIO4; room temperature for the indicator reaction. A linear calibration characteristic was obtained under chosen optimal conditions in the range of iridium concentrations (0.2 – 2.0) × 10 – 5 μg/ml. The effect of the elements accompanying iridium in industrial and natural materials was studied. Molar excesses of platinum and non-ferrous metals do not interfere with iridium determination: 20-fold Rh (III); 15-fold Pt (IV) and Fe (II); and 20-fold molar excess of Ni (II). Correctness of the results is confirmed by spike recovery tests on model iridium-containing solutions. Sr of the results of iridium determination under selected conditions at n = 3, P = 0.95 on model solutions is no more than 0.04. A comparison of the obtained results with literature data showed that the main advantages of the proposed method for iridium determination are room temperature of the reaction, more simple hardware design and lower limit of the iridium determination.

Published: May 2020

The purpose of this study was to implement information literacy (IL) into Science, Technology, Engineering, and Mathematics (STEM) writing courses at an urban community college, investigate if students’ information literacy (IL) skills were improved through library one-shot instruction, and determine if there was an association between IL skills and students’ writing performance. Students in the experimental group attended the library instructional class and students in the control group had no library class. Students’ research papers were scored using the Association of American Colleges & Universities (AAC&U) Information Literacy VALUE Rubric to grade the effectiveness of the library instruction. While the scores of the papers did not differ between groups, data indicated that there was a statistically significant difference (p = .011) in IL scores between students in the experimental group (M = 9.70) and students in the control group (M = 8.73). The results also showed that information literacy skills were correlated positively with students’ grades on research papers (p = .002).
The Anticancer Activity and Mechanisms of Ginsenosides: An Updated Review
Authors: Chen Hongwei , Yang Haixia , Fan Daidi , Deng Jianjun
Published: May 2020

The annual global mortality rate of cancer has increased dramatically. Although various therapies are used for cancer, the results have not been satisfactory. Chemotherapy is currently the most common treatment option. However, serious side effects and drug resistance impede the therapeutic efficacy of chemotherapeutic drugs. Increasing evidence has shown that ginsenosides as a type of phytochemicals play an important role in the prevention and treatment of cancers, such as colon cancer, cervical cancer, ovarian cancer, breast cancer, lung cancer, pancreatic cancer, bladder cancer, esophageal cancer, and bone cancer. Ginsenosides block a variety of enzymes required for tumor growth, which regulate an array of cell progression, such as nitric oxide synthase activity, protein kinase activity, epidermal growth factor receptor intrinsic kinase activity, and nuclear factor‐kappaB activity. Ginsenosides also inhibit lipid peroxidation and the production of reactive oxygen species. Thus, ginsenosides can be used as an adjuvant to conventional cancer therapies to improve efficacy and/or reduce side effects through synergistic activity. In this review, we summarized the latest research advances of the anticancer effects of ginsenosides and their potential mechanisms.

On the Syncretism in Lexical Semantics
Authors: Eremin A. N.
Published: May 2020

The article deals with the questions of syncretism in lexical semantics of words belonging to different parts of speech in two aspects: the syncretism of properties of lexical meanings and the syncretism of lexical meanings. Three types of nomination meanings are singled out: 1) nomination meaning oriented on either a person or an animal, or an object (nomination of one denotative area); 2) evaluative meaning which is simultaneously oriented on a person, animal and an object (characterizing three denotative areas); nomination evaluative meaning oriented on one denotative area naming and characterizing it at the same time. The article provides examples of the syncretism of direct and metonymic, several metonymic, direct and metaphoric, metonymic and metaphoric meanings. Theoretical issues are illustrated by examples from fiction.

Aim: Paracetamol is widely used by important societal groups such as pregnant women and the elderly. Paracetamol, taken in high doses especially during pregnancy, causes liver failure. The aim of our study is to investigate the effects of paracetamol, which is widely used during pregnancy, on the fetal liver. Methods: In our study, five groups of randomly selected rats from 10 Wistar Albino rats (n=2) were formed as control group, 50 mg / kg paracetamol group, 125 mg / kg paracetamol group, 250 mg / kg paracetamol group and 500 mg / kg paracetamol group. Paracetamol by gavage was given to pregnant rats in specified doses. Fetuses were taken by cesarean on the 20th day of pregnancy (10 fetuses were taken from each group). The fetus livers were then taken for biochemical analysis. Biochemically, vascular endothelial growth factor A (VEGF-A), FETU-A (FETUIN-A) (α2-heremans-schmid glikoprotein) and Sclerostin (SOST) values were examined.Results: In this study, changes in liver hepatocyte cells are seen as the dose of paracetamol increases. Regular increase is observed in VEGF-A and FETU-A. SOST increased at a dose of 250 mg / kg and decreased in the group of 500 mg / kg paracetamol. (p<0.05).Conclusions: As a result, it is seen that the use of high doses of paracetamol in pregnancy causes changes in the liver and many biochemical values on the fetus. We think that an overdosing of paracetamol, which is sold without prescription and used as an innocent analgesic during pregnancy, should be examined and this study will be a reference for other studies to be conducted.

Aim: The aim of this study was to evaluate the correlation between gait analysis and clinical and radiographic results in patients operated for slipped capital femoral epiphysis (SCFE).Materials and Methods: This study included 31 patients with unilateral SCFE. The mean follow-up time was 3.3 ± 1.4 years. Harris hip score (HHS) and the Pediatric Outcomes Data Collection Instruments (PODCI) scores were collected. Slip-angle, alpha-angle, lateral femoral head ratio (LFHR), articulotrochanteric distance (ATD), anteroposterior plane femoral head ratio (AP-FHR), anterior head-neck offset ratio (HNOR), and neck-shaft angle (NSA) were measured. An age-matched control group consisting of 20 healthy individuals was used for comparison. Results: Transfer and basic mobility subscale of PODCI was correlated with pelvis tilt ROM (r = −0.7, p < 0.001), foot progression angle (FPA) ROM (r =−0.4, p=0.02), and mean spine tilt (r=−0.6, p<0.001). FPA was also correlated with the HHS (r=−0.5, p<0.001) and pain/comfort subscale of PODCI (r=−0.5, p=0.015). Significant correlations were detected between LFHR and mean hip flexion (r=−0.5, p<0.001), pelvic tilt (r=−0.4, p=0.04), and mean spine tilt (r=0.6, p<0.001). Correlations between ATD and mean internal rotation of the hip (r=0.5, p=0.03) and mean dorsal ankle extension (r=−0.4, p=0.03) were also significant. No significant correlation was found between the alpha angle, AP-FHR, and HNOR with the kinematic values.Conclusion: Clinical scores of patients treated for SCFE were mostly correlated with pelvic tilt ROM, FPA, and spine tilt. LFHR and ATD were observed as the most critical radiological measurements related to a patient’s gait function.
What is gray literature and how to search for it?
Authors: ÇALIŞ Hasan , ASLAN Ahmet
Published: May 2020

The term gray literature refers to printed or electronic research that is either unpublished or has been published in non-commercial form. Many systematic reviews and meta-analyzes do not include gray literature sources and studies published in languages other than English. Their inclusion increases accuracy and can reduce systematic errors. it is very important to include the gray literature in the screening among the sources while conducting scientific studies, in order to obtain evidence-based results. Acta Medica Alanya journal includes gray literature especially in its compilation and editorial writings and supports citing articles from our country including Turkish in its research articles.
Impact of mindfulness-based cognitive therapy (MBCT) on anxiety, depression, and subjective happiness in Russian first-year psychology students
Authors: Skolzkov Anton
Published: May 2020

Globally, there has been an increase in the number of
people with anxiety disorders and depression which is confirmed by particular Russian
data. Despite overall improvements in the global economic situation in recent
decades, general stress levels have not decreased. University freshmen are particularly
vulnerable to stress. Therefore, this pilot study assesses the effectiveness of
mindfulness training aimed at maintaining Russian students’ mental and physical
health. The participants were 83 freshmen from the Psychology Department of Ural
Federal University named after B.N. Yeltsin. Data collection was completed in
November 2019. A non-randomized controlled trial was conducted using a mindfulness-based
cognitive therapy (MBCT) program. Results show that MBCT reduced depression and
increased subjective happiness among first-year psychology students. Frequent mindfulness
meditation practice and studying theoretical materials is associated with
higher rates of positive results. The findings suggest that MBCT can be
effective in working with first-year students in the Psychology Department of
Ural Federal University. Nevertheless, further research is required before implementing
the program on a broad scale in Russian universities.

When supervision is faced with performance and quality control of education, it certainly has a different mission from supervision by the school principal. It aims to provide services to school principals in developing the quality of educational institutions and facilitating school principals to be able to manage institutions effectively and efficiently.So, education supervision is really needed to review the extent of the professionalism of teachers in teaching and how teachers interact with their students in school in achieving interesting and controlled learning goals later.The purpose of educational supervision is to help teachers to better understand / realize the goals of education in schools, and the function of schools in an effort to achieve educational goals. The main purpose of supervision is to improve teaching. The general purpose of supervision is to provide technical assistance and guidance to teachers and staff so that the personnel are able to improve the quality of their performance, in carrying out their duties and carrying out the teaching and learning process.The final benefit of the supervision process is something that is not easy in the personnel management system in Indonesia, such as to do mutations, demotion, let alone dismiss school staff who are incompetent. This is also the case with curriculum changes that are highly centralized, which do not show the differences in each school. However, whatever the obstacles are, supervision activities must still be carried out, even if only to very modest limits
