Primary vitreoretinal lymphoma: recent advances and literature review

Primary vitreoretinal lymphoma is a rare B-cell intraocular malignancy, commonly considered as a subset of primary central nervous system (CNS) lymphoma. Brain dissemination occurs in 60–90% of patients and it is the cause of the high mortality and morbidity of the disease. PVRL involves the vitreous, the retina, and the retinal pigment epithelium (RPE). The majority of patients complain about hazy vision and floaters occurring for several months. PVRL commonly masquerades as posterior uveitis, with a misleading temporary response to steroids, responsible for its late diagnosis. Fundoscopy and advanced imaging tests such as optical coherence tomography (OCT), fluorescein angiography (FA) and fundus autofluorescence help in the diagnosis, as different peculiar findings have been described. Nevertheless, cytology and immunohistochemistry of vitreous samples are required to confirm PVRL diagnosis. Vitreous and aqueous interleukin analysis (IL-6/IL10 ratio) and mutated gene detection (MYD88 L265P) have recently demonstrated high reliability. Several treatments are available for PVRL, including methotrexate (MTX) and rituximab intravitreal (IV) injections, radiation therapy and systemic chemotherapy. However, due the rarity and the complexity of the disease, literature about vitreoretinal lymphoma is limited and definite guidelines are lacking. The aim of this review is to highlight crucial points and recent advances useful for the diagnosis, management and treatment. Indeed recently, novel imaging tools in conjunction with new molecular diagnostic techniques have helped in distinguish typical vitreoretinal lymphoma features. Furthermore, we present different experience on treatment and the available data on follow up. Herein, we try to address the lack of univocal consensus in management of patients with vitreoretinal lymphoma and the desperate need of multicenter studies to define the optimal management for PVRL, especially when CNS involvement has developed.
Determination of chitin content in shells of selected crab species available in Jaffna

In the post-war context, Jaffna crab industry is developed, exporting live, fresh de-shelled and processed crabs all around the world. Human consumes only 40% of the crab’s weight as meat and the rest is thrown into the environment as waste shell. This unutilized waste crab shell contains large amount of chitin which can be extracted and utilized for different applications in cosmetics, agriculture, food, medicine and waste water treatment. The present study was carried out to find out the chitin content in selected, most abundant crabs such as Portunus pelagicus, Thalamita crenata and Portunus sanguinolentus available in Jaffna peninsula, during the period of July October, 2017. Crabs were deshelled and the shells were dried, ground and screened through < 0.5 mm sieve. Fine particles of the crab shells samples were deproteinized by treating with 3.5% (w/v) NaOH solution and demineralized by treating with 1 N HCl. The extracted chitin was confirmed via the functional group using Fourier Transmission Infrared Spectroscopy. Higher yield percentage of extracted chitin was observed in the shells of Portunus sanguinolentus (23.38±1.11%) than Portunus pelagicus (15.39±0.73%) and Thalamita crenata (15.84±1.30%). The study revealed that the percentage of protein and calcium carbonate in Portunus sanguinolentus are 18.94± 1.74% and 62.29±1.92%, in Portunus pelagicus are 22.91±2.03% and 61.70±1.97% and in Thalamita crenata are 15.24±1.45% and 68.92±1.70%, respectively.
Breathiness in speech directed to 4-month-old infants

Introduction. Mothers tend to speak differently to infants than to adults. This register is referred to as motherese or infant-directed speech (IDS), whereas the one used talking to adults is called adult-directed speech (ADS) [1]. Higher fundamental frequency and slower speech rate are the most typical characteristics of IDS compared to ADS [1, 2]. There is rather sparse data available on the voice quality features of IDS, and it has not been in the focus of previous research. Meanwhile, in other areas of speech entrainment studies voice quality is gaining increasing attention. Its several measurable acoustic parameters make voice quality a useful indicator of speech entrainment [3] and facilitate the identification of positive emotion expressions [4], which are fundamental features of IDS. A recent study has found that on average vowels were produced with more breathy voice quality in Japanese speech directed to 20-month-old infants than in ADS [5]. However, it remains unknown whether the occurrence of breathiness is a universal feature of motherese and whether it already appears in the first year of the infants’ lives or at a later stage. The present study aims to investigate the voice quality characteristics of Hungarian speech directed to 4-month-old infants.
Fear of coronavirus and forbid/allow asymmetry as determinants of acceptance of COVID-19 pandemic related restrictions and persistence of attitudes towards these regulations

In this study (N = 110) factors influencing formation of attitudes toward COVID-19 related restrictions as well as factors influencing stability or change of these attitudes were tested. Specifically, the study concentrated on two possible determinants of formation and changing attitudes toward COVID-19 related restrictions – fear of coronavirus and presenting restriction in forbid vs. allow frames. A restriction presented in the forbid frame was rejected more strongly than a restriction presented in the allow frame. For changing attitudes, a mere thought paradigm was used. This activity was not able to change these negative attitudes toward a forbid framed restriction. A higher level of fear of coronavirus was related to a more positive (or rather – less negative) attitude toward an allow framed restriction and allows this attitude to be changed to be more supportive of restrictions than initially. Moreover, the effect of fear was partially mediated by the changes in the confidence of initial attitude inconsistent thoughts.
Durable and Short-Term Left Ventricular Assist Devices for Decompensated Heart Failure

The prevalence of heart failure continues to increase in the United States, and the number of patients supported with mechanical circulatory support devices parallels this trend. Left ventricular assist devices (LVADs) have evolved signifi cantly over the past 70 years, temporizing patients to recovery, durable devices, transplantation, or serving as destination therapy. In this review, we briefl y summarize the evolution, outcomes, and operative considerations for contemporary durable devices, and we provide an overview of short-term assist devices (Impella, TandemHeart).
Effect of Resilience Intervention on Nurses' resilience and Psychological Problems during The COVID-19 Pandemic

Recommendations: Continuous training intervention that targeting and enhancing resilience are important to be planned and implemented to improve psychological wellbeing among frontline nurses who are caring with patients infected with corona virus.
Does earnings management exert pressure on firms' return on assets and equity?: The case of Sub-Saharan Africa

In the accountancy literature, there is robust empirical evidence on earnings management, with various phrases used to depict the concept such as income smoothing, accounting hocus-pocus, aggressive accounting, engineering accounting, and creative accounting, among others. Conceivably, the widespread literature on earnings management may be associated with the varied usage of earnings management phrases together with cravings by firms to beat earnings management practices. Interestingly, the literature on earnings management is staggered by remarkable, but divergent results (Jones, 1991; Dechow, Sloan & Sweeney, 1995; Zunera, DOES EARNINGS MANAGEMENT EXERT PRESSURE ON FIRMS’ RETURN ON ASSETS AND EQUITY? THE CASE OF SUB-SAHARAN AFRICA

The Eﬀect of the Maqashid Sharia Index, Company Size, and Company Age on Islamic Social Reporting

Islamic social reporting is the application of social functions that are based on sharia provisions. It does not only help the Muslims in deciding but also helps companies to fulfill their obligations to God and the community. This study aims to obtain empirical evidence on the influence of maqashid sharia index, company size, and company age on Islamic social reporting and the example is the 11 sharia banks in Indonesia. This study takes about 4 years (2015-2018) and the analysis technique was a descriptive and statistical analysis. Statistical analysis uses the Partial Least Square approach (Smartpls version 3.0) and the result is indicated that the maqashid sharia index, company size, and company age have a positive effect on Islamic social reporting. This study empirically proves that a sharia bank that is able to express the maqashid sharia index well then has good Islamic social reporting disclosure. The sharia banks that have high total assets and income tends to make an extensive Islamic social reporting disclosures because there are also more sources of funds used to make disclosures. The longer sharia bank is established, the higher level of Islamic social reporting disclosure.
Smartphone Addiction among Nursing Students in Higher Learning Institutions

Smartphone Addiction Students Higher Learning Institutions Smartphone has more advanced computing skill hence making the use of a smartphone possible for varied purposes and objectives. However, the negative side of the smartphone usage is ignored by many people especially among the younger generation. Thus, this study is to provide some information about smartphone addiction among nursing students in a public university. Cross-sectional survey was carried out at Universiti Teknologi MARA (UiTM) Puncak Alam Campus, from December 2018 to January 2019. The questionnaire was distributed to the nursing students to assess their smartphone addiction. A total of 212 questionnaires were distributed during the data collection procedure and out of these 200 questionnaires were completed and returned by the respondents. The total mean of smartphone addiction scale was found to be moderate. The study found that there is a correlation between smartphone addiction with age and Cumulative Grade Point Average. The study concludes that it is important to create awareness on smartphone addiction especially among younger students and students those who have low CGPA scores. Several recommendations were put forward as guidelines to minimize smartphone addiction.
Travel Demand Nowcasting

16. ABSTRACT Predictive models of urban mobility can help alleviate traffic congestion problems in future cities. State-of-the-art in travel demand forecasting is mainly concerned with long (months to years ahead) and very short term (seconds to minutes ahead) models. Long term forecasts aim at urban infrastructure planning, while short term predictions typically use high-resolution freeway detector/camera data to project traffic conditions in the near future. In this report, we present a medium term (hours to days ahead) travel demand forecast system. Our approach is designed to use cellular data that is collected passively, continuously and in real time to predict the intended travel plans of anonymized and aggregated individual travelers. The traffic conditions derived through traffic simulation can overcome the data sparsity for short term prediction. The data resolution, prediction tolerance and accuracy for medium term travel demand forecast are compromises between those of long term forecast and short term prediction.
Plant height control of obligate long day herbaceous annuals using plant growth retardants and light

To control plant height of obligate long day plants, two trials were conducted, that is the use of plant growth retardants (A-Rest, Bonzi, and Cycocel), excluding control and exposure of plants to light for specific time (2, 4, 6 and 8 weeks). Results indicated that plant height was significantly reduced by all plant growth retardants. Similarly, plants transferred to a short day (SD) light chamber for 2 weeks produced more or less similar plant height when compared to plant growth retardants. The study suggested that for taller plants production the duration can be prolonged up to 8 weeks. The use of light to control plant height is non-toxic and eco-friendly. Key word: Obligate long day, herbaceous annuals, plant height control, plant growth regulators, light
Exploring the relationships between L2 vocabulary knowledge, lexical segmentation, and L2 listening comprehension

The capacity to perceive and meaningfully process foreign or second language (L2) words from the aural modality is a fundamentally important aspect of successful L2 listening. Despite this, the relationships between L2 listening and learners’ capacity to process aural input at the lexical level has received relatively little research focus. This study explores the relationships between measures of aural vocabulary, lexical segmentation and two measures of L2 listening comprehension (i.e., TOEIC & Eiken Pre-2) among a cohort of 130 tertiary level English as a foreign language (EFL) Japanese learners. Multiple regression modelling indicated that in combination, aural knowledge of vocabulary at the first 1,000-word level and lexical segmentation ability could predict 34% and 38% of total variance observed in TOEIC listening and Eiken Pre-2 listening scores respectively. The findings are used to provide some preliminary recommendations for building the capacity of EFL learners to process aural input at the lexical level.

Does the Crisis Change the Nature of Agglomeration Economies in Indonesia?

By examining their source and magnitude, this paper looked at the changes in the nature of Indonesia’s agglomeration economies over three distinct, successive periods: the pre-crisis boom (1990–1996), the deep crisis (1997–2000), and the post-crisis recovery (2001-2010). We found that economies of localisation and urbanisation are both present during the observation periods, with the former generating a stronger effect than the latter. Furthermore, types of agglomeration externalities have significant relationship with variations in size of plants and industrial sectors. These factors shed some light on the nature of agglomeration economies and how the agglomeration sources changed across the crisis periods in favour of localisation economies. The results also demonstrate the industry life cycle at work, as evidenced by changing industry structure during the recovery period.
University of Birmingham Viscoelastic Properties of Human Bladder Tumours

The urinary bladder is an organ which facilitates the storage and release of urine. The bladder can develop tumours and bladder cancer is a common malignancy throughout the world. There is a consensus that there are differences in the mechanical properties of normal and malignant tissues. However, the viscoelastic properties of human bladder tumours at the macro scale have not been previously studied. This study investigated the viscoelastic properties of ten bladder tumours, which were tested using dynamic mechanical analysis at frequencies up to 30 Hz. The storage modulus ranged between 0.052 MPa and 0.085 MPa while the loss modulus ranged between 0.019 MPa and 0.043 MPa. Both storage and loss moduli showed frequency dependent behaviour and the storage modulus was higher than the loss modulus for every frequency tested. Viscoelastic properties may be useful for the development of surgical trainers, surgical devices, computational models and diagnostic equipment.
The concept of a ratio analysis of consolidated financial statements applied to listed capital groups on the example of the Deutsche Börse Group

Purpose: The article concerns the ratio analysis of consolidated financial statements. The aim is to en-courage and conduct a discussion about its specifics and usefulness. Methodology/approach: The concept of ratio analysis of consolidated reporting created by Karmańska in 1999 (and later verified) is presented. The advantages of this analytical method were illustrated on the example of the corporate group of the German stock exchange operator. Findings: The concept has shown its usefulness in identifying aspects of business activity that are specif-ic for capital groups. The authors recommend its usage either fully or to a limited extent, depending on the area of analysis where functioning in a capital group matters and can enrich the reasoning. Research limitations/implications: This article does not present the results of direct empirical studies conducted using the proposed analytical approach but is oriented on a specific aspect of business activity assessment. It is aimed at a wider community of academics and practitioners verifying the proposed analytical concept. Originality/value: The article concentrates on the specifics of consolidated financial statement analysis, which has, until now, been present in the literature only to a limited extent. Moreover, this is the first work where a detailed financial analysis of a stock exchange operator was performed.
