Role of intestinal microbiome in the pathogenesis of age-related macular degeneration

Background: The microbiome is strongly linked to many extra-intestinal disorders. Gut commensal microbiota, in particular, plays an active role in human immune and intestinal homeostasis. Complex interactions of the microbiota with host genetics and other underlying factors lead to intestinal dysbiosis, which is thought to be linked to ocular inflammatory diseases. Thus, the aim of this review is to analyze the role of intestinal microbiome in age-related macular degeneration (AMD). Methods: A thorough literature search was performed using PubMed/MEDLINE, limited to English language publications, from January 2004 to March 2020. An additional search was made employing Google Scholar to complete the collected data as per the above-mentioned time-line and language limitations. The main keywords used included age-related macular degeneration, microbiome, dysbiosis, autoimmunity, gut microbiota, epigenetics, immune-mediated inflammatory diseases, and gut-retina axis. Results: Recent studies have proposed the role of intestinal microbiota in the pathogenesis of AMD. Changes in the microbiome have been shown to trigger several ocular inflammatory processes. There is increasing evidence demonstrating that intestinal microbial imbalance may play an important role in the pathogenesis of AMD. Conclusions: This review summarizes how alterations in the intestinal microbiota can be associated with the pathogenesis of AMD and how new therapeutic modalities can be designed to target this microbiome to limit the severe nature of this disease. Future advances in microbiome research may unveil a new era in understanding and managing AMD.
Educational DataMining: A Study of the Factors That Cause School Dropout in Higher Education Institutions in Brazil

Context:In Brazil, there is a high dropout rate in higher education institutions. Thus, it is clear that evasion is a frequent problem and that it is necessary to analyze the factors that cause it to enable solutions that can mitigate/ reduce this problem. Objetive: (1)perform a correlation analysis (Pearson and Spearman) of the educational factores of the School Census; (2)propose school dropout prediction models taking into account educational and economic factors using regression methods (linear, robust, ridge, lasso, clusterwise regression). Methodology: used the phases of the CRISP-DM methodology. Results: the factors related to not allowing financial assistance are related to as evasion, namely: food, permanence, didactic material, transportation. There are also factors related to the study period. The regression robust and linear regression show fewer errors. Conclusion: the correlations used present the selection of factors in a similar way, thus following a linear distribution. This study can help to create more investment in public policies, as it ratifies factors are related to this dropout problem.
Parkinson’s Disease : An Update on Pathophysiology, Epidemiology, Diagnosis and Management Part 4 : Differential Diagnosis and Patient Assessment

Early symptoms of PD are subtle and occur gradually. Patients may be tired, or experience a general malaise. Many may feel a little nervous or may have trouble getting out of a chair. We can note that they talk too softly or that they look messy and spidery in their handwriting. They may lose track of a word or thought or they may, for no obvious cause, feel irritable or discouraged. This early period can last a long time before the symptoms appear more classic and obvious. The onset of symptoms will take several years to go unnoticed. Symptoms usually impact only one side of the body for one or two years, then move to the other side. Tremor is always first detected, which usually causes the doctor’s first appointment. Nevertheless, there is no tremor in up to 30 per cent of patients; this may lead to a misdiagnosis. In this review the approach to assessment and differential diagnosis of Parkinson disease are discussed.
Increasing Supercapacitor Features Using Reduced Graphene Oxide@Phosphorus

Supercapacitors have attracted much attention in the field of electrochemical energy storage. However, material preparation and stability limit their applications in many fields. Herein, a reduced graphene oxide@phosphorus (rGO@P) electrode was prepared using a simple inexpensive method. The new graphene structure (rGO@P) was characterized by X-ray di raction, Fourier transform infrared spectroscopy, scanning electron microscopy and Energy-dispersive X-ray spectroscopy. Electrode showed excellent performances (307 F g−1), which seem to be the highest among many other rGO@P-based electrodes reported so far. It also has an excellent cyclic stability up to 95% after 600 consecutive charge/discharge tests. So, the ease of the synthesis method and excellent performance of the prepared electrode materials mat have significant potential for energy storage applications.
The Role of Media Use and Emotions in Risk Perception and Preventive Behaviors Related to COVID-19 in South Korea

The relationship between compliance with behaviors recommended to prevent the spread of COVID-19 and media exposure, negative emotions, and risk perception was examined using regression analyses of data from KAMOS, a nationally representative survey of South Korean adults. The strongest predictor of preventive behaviors in general was negative emotions, which had the largest *βh* (.22) among the independent variables considered. The eight negative emotions, identified using factor analysis of a series of 11 emotions, were anger, annoyance, fear, sadness, anxiety, insomnia, helplessness, and stress. Negative emotions themselves were influenced most strongly by the respondent’s anxiety over social safety (*βf*=.286), followed by prediction of COVID-19 spread (*β*=.121, *p*<.001) and perceived risk of COVID-19 infection (*β*=.70, p=.023). Females (*β*=-.134) and those who felt less healthy (*βo*=-.097) experienced more negative emotions. Media exposure and increased media exposure both have significant relationships with negative emotions and both a direct and indirect impact on the adoption of preventive measures. Women, older people, and healthier people perceived greater risks and engaged in more preventive behaviors than their counterparts.
Synthesis of densely branched poly(methyl methacrylate)s via ATR copolymerization of methyl methacrylate and ethylene glycol dimethacrylate

Densely branched poly(methyl methacrylate)s have been synthesized by copolymerization of methyl methacrylate (MMA) and ethylene glycol dimethacrylate (EGDMA) using atom transfer free radical polymerization (ATRP). By employing the phenyl and benzyl esters of 2-bromo-2-methylpropionic acid as the initiators with 2,2-bipyridyl and Cu(I)Cl it has been possible to use high field 1H nuclear magnetic resonance spectroscopy to evaluate in some detail the composition and structure of the branched PMMAs obtained. Parallel molar mass size exclusion chromatographic analysis using a multi-angle light scattering detector with a refractive index detector (MALS/SEC) has allowed the branched architecture of the products to be confirmed. Rather remarkably, high yields of branched PMMAs can be obtained without crosslinking using MMA/EGDMA molar feed ratios of up to 5/1 by appropriate adjustment of the molar feed of initiator. In particular by maintaining the EGDMA/initiator molar feed ratio ∼1/1 fully soluble products can be obtained that are densely branched since this feed ratio ensures that on average each living primary chain initiated contains on average only one branching EGDMA segment. As might be expected this controlled free radical process offers better control in the synthesis of branched polymer than the corresponding system we have reported using conventional free radical polymerization, and unlike the latter which requires the use of a chain transfer agent, the ATRP system requires no additional chain regulating component.
Financial Deepening and Entrepreneurial Growth in Nigeria: A Time Series Analysis (1986 – 2018)

This study examined the effect of financial deepening on entrepreneurial growth in Nigeria. Following the approach of the Granger Causality test with Autoregressive Distribute Lag (ARDL) technique of model estimation using data from 1986 to 2018, there is no significant effect of financial deepening on entrepreneurial growth. Entrepreneurial growth was found to have significantly influenced financial deepening through banking and insurance sector deepening. Consequently, the Central Bank of Nigeria (CBN) should encourage commercial banks to lend more for entrepreneurial activities which will in turn improve our gross domestic product. This can be achieve if the CBN can lower its monetary policy rate to a single digit as against the current double digit (14%). It would be ideal for the government (Federal, State and Local) to establish entrepreneurial training/skill acquisition centres in all tertiary institutions in the country. This will help a large fraction of the graduates of these institutions to inculcate entrepreneurial spirit to setting up small and medium scale enterprises in every part of the country.
The magnetoresistance of Pd-based dilute ferromagnetic alloys

The isotropic and anisotropic magnetoresistance have been measured for dilute alloys of PdFe, PdCo, PdNi at low temperatures. Physically different effects dominate in each case. In PdFe there is a temperature-dependent negative magnetoresistance from the suppression of electron-magnon scattering. In PdNi there is a positive isotropic magnetoresistance due to the effect of the magnetic field on the magnitude of the Ni moments, plus an anisotropic magnetoresistance arising from local orbital moments in Ni sites. In PdCo there is a negative isotropic magnetoresistance associated with magnetising the sample. The authors suggest that this is due to non-ferromagnetic interactions between Co moments.
Rational Organizational Structure: For Brick-and-Mortar Lifestyle Retailers in India to Overcome Diseconomies of Scale and Protect Firm’s Sustainability (ROLS-b)

A majority of organized brick-and-mortar lifestyle retailers in India believe that the brick-and-mortar retailing model ensures economies of scale as they keep opening new stores. Having more stores might help retailers to gain product sourcing advantages in addition to generating additional revenue to the firm but at the same time, it fails to provide any other benefits towards economies of scale as every new store comes with new one-time capital expenditures and recurring fixed expenses. Another misconception is that lifestyle retailing must follow an organizational structure (OS) that is adopted by their parent company and hence a majority of OS adopted by lifestyle retailers in India is dependent on organizational form. This study was not limited to just recommending a rational OS based on exploratory research and existing theories in the OS domain. Once the ROLS-b was designed, we have experimented with the proposed rational OS on one of the ten lifestyle retailers in the study to test the validity and reliability. Experimentation results empirically and qualitatively demonstrate that the existing belief of brick-and-mortar lifestyle retailers in India which assumes economies of scale and long-term firm’s sustainability as the retailer increases the store count is just a misconception and does not hold. On the other hand, when we experimented the ROLS-b for over twelve months at over 25 percent stores of a select retailer, results demonstrate that these stores which have gone through the treatment have shown 5.34 times improvement in the store-level profit and 1.97 times in the firm-level profit in addition to eliminating a majority of gaps found in the existing OS that was leading to diseconomies of scale and deteriorating firm’s performance.
THE SYNTHESIS OF HIGH-QUALITY DIAMOND IN COMBUSTION FLAMES

High‐quality diamond with good crystallinity has been successfully synthesized on a substrate using an oxy‐acetylene combustion flame in the atmosphere. The crystal grains under some conditions have good optical transparency. The deposition rate of transparent diamond depended strongly on substrate temperatures and the O2/C2H2 ratio and averaged ∼30 μm/h. The substrate temperature for the growth of optically transparent crystals was 500–750 °C, which is relatively low compared with other chemical vapor deposition methods. The optical transparency is attributed to the low defect densities in the crystals, as determined by transmission electron microscope, which results from the low substrate temperatures and moderate growth rates. Raman spectroscopy and x‐ray diffraction data on the synthesized crystals were comparable with that of natural diamond. The synthesis conditions and corresponding diamond quality as well as emission spectrum analysis of the combustion flame during diamond synthesis are described.
Pengaruh Kondisi Kapasitas Lapang Yang Berbeda Terhadap Pertumbuhan Vegetatif Varietas Kacang Hijau (Vigna radiata L.)

Mung beans are planted with the ability to tolerate drought. Easy cultivation techniques that make green beans have business opportunities in the field of agribusiness. Nevertheless, the growth of mung bean plants is influenced by varieties. The lack of use of superior varieties of marginal land will result in a lack of plant growth, because currently agricultural land is increasingly shifting to less fertile land, one of which is the lack of availability of water in the soil for plant growth. Therefore, this study was conducted to determine varieties and conditions of field capacity that are suitable for the vegetative growth of mung beans. The study was conducted at the Screen House and Plant Protection Laboratory with factorial RAK consisting of factors of mung bean varieties (Vima-1, Vima-2, Vima-3 and Kutilang) and conditions of field capacity (100% KL, 80% KL, 60% KL, 40% KL and 20% KL The results of the observations were analyzed in a variety of ways and tested further with Duncan's Multiple Range Test (DMRT) level of 5 %. The results showed that the interaction between varieties and field capacity affected the diameter of mung bean stems. Other vegetative: Vima-3 varieties obtained the highest average number of leaves, greenish leaves and leaf area, the highest average plant height, stem diameter, number of leaves and leaf area were obtained at 80% KL conditions. Vima-3 gets the best vegetative growth while the field capacity that is suitable for the vegetative growth of mung beans is
Work Life Balance Post COVID-19

The two most important domains of an individual’s life are work and family. Work and Home can be called two different domains that people have associated with different rules, thought patterns and behaviors. The ability of workers to balance their work and family lives depends on the characteristics of their jobs as well as their individual and family variables and situations. One of the key potential areas of conflict associated with work-life balance relates to travel-to-work. Work-life issues are particularly sensitive to national contexts. Certainly, for most people, different roles and the management of them are desirable. Most people are multidimensional, and work and life are complementary. Conflict is often caused by the incompatible personal expectations of work and life roles. The forced lockdown during COVID-19 has not improved the work life balance for most people even though they were able to spend more time with family and there was no commute time. Many have lost the fascination for exotic places and may prefer to go nearby places for leisure as there is much fear in travel especially international one. These will have a great impact on the tourism industry post COVID-19 as food, travel, stay and leisure activities are the main components of tourism.
Web-Based Interventions to Promote Healthy Lifestyles for Older Adults: Protocol for a Scoping Review.

BACKGROUND With the aging of the population and rising rates of chronic diseases, older adults need support if they are to adopt healthy lifestyles. Web-based interventions should be considered for this purpose, since they are easily accessed and can foster healthy lifestyles among older adults. However, the literature on such interventions discusses a variety of components and effects and provides only 2 syntheses of knowledge on web-based interventions with older adults. These studies focus on populations aged 50 years and older, whereas the components and effects of interventions for a population of older adults (ie, 65 years and older) may differ. In addition, these 2 syntheses examined only quantitative studies, although other types of studies (ie, qualitative) are available and could help advance knowledge in this field. A scoping review is therefore relevant in order to explore the extent of the literature on this subject. OBJECTIVE The purpose of the study described by this protocol is to explore the extent of the literature (experimental, quasi-experimental, qualitative, systematic reviews, and grey literature) on the components and effects of web-based interventions as a way to promote healthy lifestyles among older adults. METHODS The databases MEDLINE, CINAHL, PsycInfo, Web of Science, Cochrane Database of Systematic Review and Joanna Briggs Library will be searched, in addition to the grey literature using Google Scholar and OpenGrey. Studies will be selected for the review by 2 researchers, working independently. The data will be synthesized based on the conceptualization of web-based interventions (ie, behavior change techniques, dispensation modes, and theories). A thematic analysis will be performed to summarize the components of the interventions studied. RESULTS The database search will begin in August 2020 and be completed in October 2020. CONCLUSIONS This scoping review should highlight web-based interventions designed to promote healthy lifestyles, as well as their components and effects, among people aged 65 years and older. These results could provide important guidance for intervention developers and designers in identifying the components of web-based interventions relevant to older adults and lead to further studies on this topic.

Why Firms Announce Good News Late: Earnings Management and Financial Reporting Timeliness

Prior studies find that delayed earnings announcements tend to communicate unfavorable news, and investors consequently react negatively when firms delay earnings announcements. However, these findings do not explain why investors discount delayed earnings, even after controlling for the earnings news, and why firms sometimes announce good news late. Motivated by theory from Trueman (1990) that attempts to explain these phenomena, we examine whether announcement delays indicate earnings management. We find that good news firms with higher discretionary accruals are more likely to announce earnings late. Consistent with post fiscal year-end activities driving announcement delays, we fail to find a relation between measures of real earnings management and late announcements. Using a last-chance earnings management measure based on tax expense manipulation, we find strong evidence that good news firms engaging in last-chance earnings management are more likely to delay earnings announcements. Consistent with Trueman’s (1990) theory that earnings management explains why investors discount delayed earnings announcements, we find that the negative relation between earnings announcement returns and announcement delays is partially driven by late announcers relying on last-chance earnings management to beat analysts’ expectations.

Effects of nitrogen fertilization on the photosynthesis and biomass distribution in a potato crop

Nitrogen fertilization has positive effects on growth and production of potato crop. The objective of this study was to assess the differences of the photosynthetic response and biomass partitioning patterns during the main phenophases of the potato cultivar Capiro under different nitrogen nutrition fertilization treatments in the tropical Andes of Merida, Venezuela. Plots of 40 m2 (2,625 plants m-2) were established under a random block design with three replications by nitrogen fertilization treatment: 0, 100, 200, and 300 kg. N ha-1. Photosynthesis and biomass were measured in the different organs in the main phenological stages of the crop. The results indicate that photosynthesis tends to increase slightly with the nitrogen supply; although the differences were not always significant and, decreases during crop growth. Tubers yield it was markedly influenced by the nitrogen fertilization. The total biomass production, as well as biomass allocation in different organs showed differences between treatments, maintaining the following order: 300-N> 200-N> 100-N> 0-N. When analyzing the biomass accumulation curves, it is estimated that the application of 250 kg N ha-1 as mineral fertilizer is enough to reach optimal production yields.
Learning Accounting Courses on Digital Platforms: How Do Non-Accounting Students Accept?

The study aimed to examine the perception and the factors influencing the online learning process of non-accounting students in accounting courses. A quantitative approach with a structured questionnaire was used for data collection and it was distributed to the non-accounting undergraduate students who enrolled in two accounting courses; Principles of Accounting and Managerial Accounting in the semester April 2020. The questionnaire consists of four dimensions; learner characteristics, technology and system, interactive application, and instructor characteristics. Of the total of 194 non-accounting undergraduate students, there were 130 respondents participated in the study. Descriptive statistics and statistical inference were accustomed analyse the mean, standard deviation, frequency, and percentage using the Statistical Package for Social Sciences version 25.0. The findings showed that there was a high-level acceptance of the non-accounting students towards learning accounting courses online. Results indicated that the instructor and learner characteristics were the two most significant influential factors of non-accounting students to learn accounting courses on digital platforms. The findings of this study cannot be generalised to other universities due to different environments and situations. Nevertheless, the implications of the study are crucial for instructors, practitioners, and institutions who are within the planning and are currently engaged in offering online learning courses.
