Structure related corrosion behavior of DLC films in high Cl− environment
Authors: Zhang Yukun , Gao Pen , Chen Dongxu , Zhou YanWen 
Published: August 2021

Abstract
The diamond-like carbon (DLC) films were successfully fabricated on the surface of 13Cr super martensitic stainless steel by plasma enhanced chemical vapour deposition, and the microstructure changed with the variation of pulse voltages of the high pulse power supply. The microstructure of the DLC films was characterized by atomic force microscope, and the corrosion behavior of the films in a high Cl− environment was analyzed by open circuit potential, polarization curve and electrochemical impedance spectroscopy. It is found that the substrate corrosion occurred first for the DLC films with open pores, followed by a substrate surface passivation before the final corrosion failure. The DLC film with closed pores can effectively prevent Cl− from attacking the substrate before the corrosion pits formed at the local defects.

Abstract

Objectives
Stem cell treatment is based on Melatonin which is crucial for lots of pathological and physiological pathways. Our aim is determining the most appropriate dose of melatonin affecting the rat adipose tissue mesenchymal stem cells.

Methods
Stem cells were isolated from male rat adipose tissue. Differentiation and characterization experiments were performed. Cell viability analyses in stem cells were used the XTT [2,3-Bis-(2-methoxy-4-Nitro-5-Sulfophenyl)-2H-Tetrazolium-5-Carboxanilide] assay. After 24 h incubation, different concentrations (0.5, 1, 5, 10, 50 µM) of extract were treated to the stem cells for 24 h, 48 and 72 h considering time and dose dependent manner. Total antioxidant status (TAS) and the total oxidant status (TOS) in control cells and melatonin treated cells (5, 10 µM) were determined Rel Assay commercial kits.

Results
In 24 h, melatonin increased cell viability in all groups. When we evaluate the effect of melatonin in 48 h, the most proliferation increase was seen at 5, 10 µM doses. When the total oxidant activity melatonin was found to be significantly lower in 5 and 10 µM dose groups of melatonin.

Conclusions
Melatonin increases the survivor of stem cells and the most effective dose is 5 and 10 µM. The reduction of the oxidative stress index as a result of treating melatonin to mesenchymal stem cells showed that melatonin is a powerful antioxidant for stem cells.

Published: August 2021

Abstract

Objectives
Leukoplakia is a white mucosal thickening and perhaps undermining change in the oral mucosa transcendently found in tobacco users. Since the tobacco utilization is extensively higher with the indigenous groups in the Asia Pacific locale, the current examination implicated the prevalence of tobacco consumption and leukoplakial lesions and the relationship between the two.

Methods
This cross-sectional study was conducted through six tribal hamlets of Chithalayath Forest range at Wayanad district of Kerala, South India. Leukoplakia screening was led by a senior consultant on the basis of a visual investigation and pathological evaluation was not done. An organized questionnaire was utilized to gather data on demographic details and tobacco usage status and frequency. The prevalence of clinical oral lesions among tobacco users and non users was determined using statistical analysis.

Results
Clinical oral leukoplakia was diagnosed in 27 (8.5%) subjects among the 317 individuals screened. The prevalence of lesions was considerably higher among tobacco consumers in comparison with non users (11 vs. 3.7%). Also, the tobacco chewers group had a higher percentage of leukoplakia. Another significant finding of this study is that the incidence of provisional leukoplakia was observed to be comparatively high among the most frequent tobacco consumers 15 (65.2%) in comparison with 8 (34.8%) in the frequent and nonfrequent users.

Conclusions
Prevalence of abusive habits and clinical oral leukoplakial was substantial among the tribes. The cause and effect relationship and dose-response were also shown to have a significant association.

Published: August 2021

Abstract
This study examines the relationship between student success measures on student achievement to inform our approach to mediating against potential barriers on persistence and retention for first generation and traditionally marginalized populations for students enrolled in a new Living Learning Community. Success measures examine those beyond the control of the university, including, but not limited to, High School GPA and ACT scores to determine where we should intervene and where we should build upon the strengths of our students. The theme of the PH LLC is Leadership Development and Career Exploration, a program that seeks to empower students by harnessing their individual strengths and capitalizing on them to be successful in college and beyond. The design of this program and its future prospects are also discussed.

Abstract
While photodynamic therapy (PDT) can induce acute inflammation in the irradiated tumor site, a sustained systemic, adaptive immune response is desirable, as it may control the growth of nonirradiated distant disease. Previously, we developed porphyrin lipoprotein (PLP), a ∼20 nm nanoparticle photosensitizer, and observed that it not only efficiently eradicated irradiated primary VX2 buccal carcinomas in rabbits, but also induced regression of nonirradiated metastases in a draining lymph node. We hypothesized that PLP-mediated PDT can induce an abscopal effect and we sought to investigate the immune mechanism underlying such a response in a highly aggressive, dual subcutaneous AE17-OVA+ mesothelioma model in C57BL/6 mice. Four cycles of PLP-mediated PDT was sufficient to delay the growth of a distal, nonirradiated tumor four-fold relative to controls. Serum cytokine analysis revealed high interleukin-6 levels, showing a 30-fold increase relative to phosphate-buffered solution (PBS) treated mice. Flow cytometry revealed an increase in CD4+ T cells and effector memory CD8+ T cells in non-irradiated tumors. Notably, PDT in combination with PD-1 antibody therapy prolonged survival compared to monotherapy and PBS. PLP-mediated PDT shows promise in generating a systemic immune response that can complement other treatments, improving prognoses for patients with metastatic cancers.
Comparative assessment of fluorine, sodium, and lithium distributions in snow cover in Siberia
Authors: Ianchenko Natalia I. , Talovskaya Anna V. , Zanin Alexey A. 
Published: August 2021

Abstract
Based on field studies of the snow cover and systematization and analysis of scientific data and technical literature data, the distributions of fluorine, sodium, and lithium, as elements included in the raw materials used for aluminum production, in the snow cover in areas proximal to Siberian aluminum smelters were considered. The results showed that the changes in concentrations of fluorine, sodium, and lithium in the snow cover near various plants have the same dispersion pattern, which can be described by an exponential relationship. Exponential relationships of diminishing concentration with distance from the emission source had high correlation coefficients. From the examples established by these relationships, an assumption was made that the behavior of these aerosols in the atmosphere is determined by the general physical and chemical properties, irrespective of the technologies and natural climatic regions of the plant locations. It is suggested that deposition of aerosols from industrial aluminium production can be achieved at a minimum distance from the plants or within the plant area through particle enlargement by various technological methods in aluminium production or by changing the atmospheric scattering capacity.

Abstract
Chemical investigation of the roots of Trichilia welwitschii yielded a cycloartane type terpenoid 28,29-bis-norcycloart-24-en-3β,4α,6α-triol (1), isolated as pure compound for the first time, three coumarins and three sterols. New cycloartane derivatives (1a) and (1b+1c) were obtained by hemi-synthetic reaction of compound 1. The structures of 1a–c were established by spectroscopic methods including 1D and 2D-NMR analysis, HR-EIMS, chemical transformations and by comparison of these data with those of related compounds. Evaluated for their antimycobacterial potential, compound 1 and 1b+1c were determined to show significant activities against Mycobacterium tuberculosis MIC values of 6.25 μg mL−1 while compound 1a displayed weak activity showing MIC > 100 μg mL−1. Compounds 2–4 displayed moderate activity with MIC values range from 12.5 to 50 μg mL−1.

Background: Melanoma is the most serious lethal skin cancer, affects the melanin producer cells (melanocytes). Surgery is the most common treatment, whereas for the advance stage the development of a treatment is recommended. BRAF (Dabrafenib and Vemurafenib) inhibitor or MEK inhibitor (Trametinib) is used as the most frequently targeted therapy of melanoma due to more than 80% patient with positive BRAF mutation. In this review, those treatments will be investigated systematically to identify their clinical outcome.Method: This systematic literature review (SLR) was performed from Cochrane, Science Direct, Google Scholar, and Pubmed. Cochrane Risk-of-Bias Tool RoB2 is used to assess RCT studies and New-castle Ottawa Scale Assessment to assess cohort studies by 3 different assessors. Data analysis was carried out by using Review Manager (RevMan 5.4). Heterogenicity test was assessed by I2 Â and Chi2 statisticResult: There are 20 studies used in this article (13 RCT and 7 cohorts). The overall survival (OS) and progression-free survival (PFS) of study that using targeted therapy (vemurafenib, trametinib, or dabrafenib) compare other therapies (chemotherapy, immunotherapy,etc) showed risk ratio (RR) was 1.12 (95%CI 1.07,1.17;Â I2=100%; p<0,00001). The OS and PFS with monotherapy compare of vemurafenib, trametinib, or dabrafenib with combination therapy showed RR was 1.09 (95%CI.06,1.13;I2=99%; p<0,00001). Conclusion: BRAF and MEK targeted therapy has a good prognosis for a patient with a positive BRAF gene mutation and could be combined with other therapy for a better clinical outcome rather than monotherapy.Keyword: melanoma, dabrafenib, vemurafenib, and trametinib

Published: August 2021

Monetary management is an essential part of the objectives of Shari’ah under the umbrella of the preservation of wealth (Ma’al). Our primary sources: Qur’an and Sunn’ah, provide divine legislation on the prohibition of Riba to manage bases of monetary transaction. Further, the juristic tools facilitate scholars to propose solutions to meet the emerging issues on diversified aspects of society. Muslim scholars have always adapted and contributed to the Islamic finance system and regulation, theoretically and practically. In recent decades, Islamic banking and finance has seen strong momentum with double digit growth, fulfilling the monetary requirement of depositors on the liability side along with industry on the asset side. We seek to review the theoretical and empirical literature on Islamic monetary mangement. Monetary management in the Islamic economic context is still an area that needs more research. This paper examines how literature has been developed over time up until modern Islamic economic and banking practices. The findings suggest that Islamic monetary management has been gradually developed in recent years and such development is remarkable steps forward in pursuing Islamic monetary policy independently. In addition, Islamic monetary policy is proved to be relatively more effective compared to interest based conventional monetary policy. The implications of such findings have established new milestones for the central banks of all the countries, including the muslim majority countries for pursuing interest free Islamic monetary policy with full confidence. Furthermore, there are four major views on Islamic monetary policy and the central banks of the world should choose one of the best methods and views for the greater effectiveness of monetary policy because conventional monetary policy has been less effective in bringing full employment and price stability in recent years and financial crisis has crippled the interest based conventional economic systems quite badly.

Published: August 2021

Zakah is an important tool in Islamic economic system, it plays a crucial role in reducing some social and economic problems such as poverty, unemployment, indebtedness and inequitable redistribution of income in the Muslim communities. The Zakah institutions in Gombe metropolis are said to practice favouritism and unfair service quality and distribution of Zakah funds among recipients. The main objective of this study is to empirically examine perception of the Zakah recipients towards the services provided by the institutions. This study adopted descriptive survey design approach. PLS-SEM is employed to test the hypothesized model of the study. The result reveals that reliability, responsiveness and assurance significantly affect performance of Zakah institutions but tangibility and empathy were found to be insignificant. The study recommends the need for Zakah institutions in Gombe metropolis to consider improving the tangibles and empathy dimensions of service quality. The study also recommends the need to concentrate on the antecedents of service quality as it will assist Zakah institutions to improve performance. Lastly, the study suggests the establishment of Zakah board that will serve as regulatory body in charge of supervising the activities of private Zakah institutions in Gombe state.

Published: August 2021

The purpose of this study was to determine the attitudes of the trainees registered in Pedagogical Formation Certificate Program (PFCP) towards the Instructional Technologies and Material Design (ITMD) course and to analyze whether these attitudes differed according to gender, department and level of grade. The data were obtained from totally 110 trainees including 78 females and 38 males. In addition to the personal information form, the Attitude Scale towards ITMD Course was used as the data collection tool. The scale had three sub-dimensions as effectiveness, admiration and denial, and the internal consistency coefficients calculated for the current implementation were between .99 and .77. It was understood that the trainees regarded the ITMD course effective enough to be considered good, admired the course at a moderate level, and did not neglect the course very much. It was noticed that female trainees found the course more effective and admired it more rather than the male trainees. The trainees in the English group were determined to consider ITMD course more effective than the trainees in the philosophy group. Moreover, it was proved that the students in the English group admired more rather than the trainees in the theology and philosophy groups. The graduate trainees regarded ITMD course more effective than the ones who were still students.

In recent years, much attention has been paid to the problem of language and correct pronunciation in the native language when working with the younger generation, including the formation of oral speech in children with hearing impairments with perspectives of special learning technologies, which formed the basis for our research work. Theoretically, the effective methods in shaping the oral skills of students with hearing impairments imply the provision of opportunities for their further successful socialization, unlimited communication with the outside world, and personality formation. In order to tackle the problem, we have identified the problem of testing methods and determining the level of formation of oral speech of students with hearing impairment, offering special methods, techniques for its improvement. In the course of implementation, diagnostic studies, quantitative and qualitative analysis of indicators, practical implementation of the methodology, and various practical works were carried out.
