Single exposure to ultraviolet irradiation and elicitation of human allergic contact dermatitis
Authors: Sjövall P , Christensen OB , Möller H.
Published: August 2023

Ultraviolet radiation has been stated to inhibit afferent as well as efferent phases of allergic contract dermatitis. In this controlled study 17 female patients with nickel allergy were studied by three different protocols after an initial determination of their degree of hypersensitivity. They were patch tested with nickel sulfate immediately after UVB, 4-6 days after UVB, or immediately after external PUVA. Neither depressing nor enhancing of the allergic reaction was observed when compared to non-irradiated controls. The role of Langerhans cells as antigen-presenting cell playing an important role in the elicitation phase of allergic contract dermatitis is discussed and questioned.

Published: August 2023

The concentrations of dopa, cysteinyldopas, 5-S-glutathionyldopa, gamma-glutamyl-5-S-cysteinyldopa and 5-S-cysteinylglycinedopa, were analysed in homogenates of cultured human melanoma cells and in culture media. Cysteinyldopas were found to be the major catechol in the cells, with a molar concentration more than a hundred times that of dopa. 5-S-Glutathionyldopa was found in the same amount as dopa, while the quantity of 5-S-cysteinylglycinedopa was one order of magnitude less. gamma-Glutamyl-5-S-cysteinyldopa was not present in detectable amounts. In the medium the concentrations of dopa, 5-S-cysteinylglycinedopa and of 5-S-glutathionyldopa were about one half of those in the cells, while the concentration of cysteinyldopas was about 2%. The ratio between 2-S-cysteinyldopa and 5-S-cysteinyldopa when incubating dopa and cysteine with tyrosinase was identical with the ratio between the analogically synthetised isomers of glutathionyldopa. Consequently, from the calculation of these ratios in cells and media one cannot deduce whether cysteinyldopas arise from the direct addition of cysteine to dopaquinone, or from degradation of glutathionyldopa. Oxidation of 5-S-glutathionyldopa gives a red chromophore with maximum absorption at 480 nm which develops into a black pigment.

Authors: Kahana M , Grossman E  , Feinstein A , Ronnen M  , Cohen M , Millet MS
Published: August 2023

Two hundred and sixteen non hospitalized patients with skin tags (ST) were studied for the presence of diabetes mellitus (DM) and obesity. Overt DM was found in 57 (26.3%) patients and impaired glucose tolerance test was found in 17 (7.9%) patients. Sixteen new cases of DM were found among this group. All the diabetic patients in the study population had non-insulin dependent DM. Sixty-two (28.7%) of the patients were obese. No correlation was found between the localization, size, colour and number of the ST and the presence of DM. Our study indicates that ST are not associated with increased incidence of obesity compared to the general population. On the other hand, ST are associated with impaired carbohydrate metabolism, and may serve as means for identifying patients at increasing risk of having DM.
T- and B-lymphocytes in pemphigus vulgaris. A clinico-immunological follow-up study of fifty patients with pemphigus vulgaris
Authors: Mashkilleyson N
Published: August 2023

Peripheral blood T-lymphocytes, studied in 50 patients with pemphigus vulgaris by means of spontaneous (E) and active (EA) rosette-formation, were increased in active disease and gradually returned to normal after achieving clinical remission of pemphigus vulgaris. The portion of B-cells quantified by M-rosette formation was increased in active disease as well (19.9 +/- 3.0% vs. 10.8 +/- 1.6% in controls) (p less than 0.02) but returned to normal immediately after clinical remission was obtained. Levamisole in vitro suppressed E-, EA-, and M-rosette formation in all the patients examined with active disease. The subsets of T-cells in 10 non-treated patients with active pemphigus vulgaris and 5 patients with a long-term steroid maintained remission of the disease were studied using OKT series monoclonal antihuman antibodies. A statistically significant increase in the percentage of OKT3+ cells (p less than 0.05) and a considerable increase in OKT4+ cell count (p less than 0.002) were registered in patients with active pemphigus vulgaris, compared with controls. In five patients with 2-9 years´ remission the percentage of OKT3+, OKT4+, OKT5+ and OKT8+ cells did not significantly differ from controls.

Authors: Liu HN , Muller SA  , Schroeter AL
Published: August 2023

Three different surface markers (OKT6, HLA-DR, and adenosinetriphosphatase) were compared to identify Langerhans´ cells, and the changes in number and morphology of these cells were studied at different intervals after irradiation of human skin by a 2.5-fold minimal erythema dose of ultraviolet A. Morphologic alteration and decreased surface-marker reactivity became evident on day 2 and were most pronounced on day 3 or day 4 (injury phase). The recovery phase started between day 4 and 1 week and was complete by 3 weeks. HLA-DR+/OKT6- (DR+T6-) cells were present at all time intervals. The ratio of these cells to the sum of DR+T6- and DR+T6+ cells was 0.3% before irradiation, reached a peak of 65.4% at day 4, and decreased to 0.6% by 3 weeks.

Published: August 2023

Omalizumab is effective in chronic spontaneous urticaria unresponsive to antihistamines. Of the licensed dosing schedules, Korean patients prefer a low dose, of 150 mg/month, for financial reasons. However, real-world experiences of low-dose omalizumab consumption have not been reported. The aim of this retrospective study was to assess the treatment outcomes and long-term clinical course of patients with chronic spontaneous urticaria who were treated with low-dose omalizumab. The study included 179 patients aged ≥ 20 years who were treated with omalizumab 150 mg/month for ≥ 12 weeks. Baseline disease activity was mild, moderate, and severe in 54.7%, 35.2%, and 10.1% of patients, respectively. A complete response was observed in 133 patients at 12 weeks, among whom 88 patients showed early responses within 4 weeks. Overall, 158 patients finally achieved a complete response. Multivariate analyses revealed that baseline disease activity is more likely to be mild in patients who experience early and final complete responses. The absence of atopic comorbidities correlated with an early response. Smoking was associated with a final complete response. This study shows that low-dose omalizumab provides favourable treatment outcomes in antihistamine-refractory chronic spontaneous urticaria. Disease severity, atopic comorbidity, and smoking may be predictive factors for studying the response to omalizumab.

Authors: S Remiddi
Published: August 2023

Background: In this study it has been evaluated the safety and the clinical performance of a new combination of topical solution based on arabinogalactan, trehalose and hyaluronic acid, in reducing symptoms and signs of inflammation in a selected population affected by dry eye disease. Methods: The study enrolled 25 patients (ranging from 57 to 71 years) with signs and symptoms of dry eye disease. They received a combination therapy with arabinogalactan, trehalose and hyaluronic acid one drop three times a day for the first week and subsequently according to their symptoms. Ocular surface disease index score, tolerability and adherence were used to evaluate subjective symptoms of dry eye disease at enrolment (T0), week 1 (T1) and week 4 (T2). Clinical signs were assessed at T0 and T2. The assessment plan included: slit-lamp examination of the anterior segment, uncorrected and corrected visual acuity, ocular protection index, tear film break up time, osmolarity, meniscometry, evaluation of conjunctival hyperemia according to Efron’s classification, the presence of MMP-9, conjunctival and corneal staining and intraocular pressure. Results: The study group showed significant improvement in several clinical parameters after treatment. Ocular surface disease index score was significantly lower at the end of the follow up period, also evaluation of tolerability (ocular burning, ocular itching and blurred vision), before and after instillation, showed a statistically significant improvement at T0 and T1. Improvements in tear film break up time, meniscometry results and conjunctival and corneal hyperemia were statistically significant in the study group (p <0.05). A statistically significant, decrease in MMP-9 levels was also observed. Conclusions: Preliminary findings suggest that the new combination of topical solution based on arabinogalactan, trehalose and hyaluronic acid, could be effective in reducing early inflammatory markers, symptoms and signs, associated with the progression of dry eye disease.

Published: August 2023

Rheumatoid arthritis (RA) is an autoimmune, chronic, and genetically linked inflammatory lesion of joint tissues that is accompanied by extra-articular systemic pathologies. The disease progression leads to joints immobilization, and eventually, the patient's disability occurs approximately ten years from the first clinical manifestation. RA pathogenesis involves various mechanisms: specific joint-related damage, nonspecific adaptive, and vessel-related pathological changes. Our research aimed to study the role of peripheral blood lymphocyte apoptosis in RA pathogenesis. We have analyzed research data from Google Scholar, PubMed, Web of Science, and Scopus databases to investigate the role of lymphocyte apoptosis in RA progression. Clinical manifestations in RA are caused by autoreactive T- and B-lymphocyte activity supported by humoral and cellular immune factors activity. Disease pathogenesis is caused by an imbalance in the process of programmed cell death (apoptosis): a proportion of immune cells are rapidly destroyed. In contrast, apoptosis is inhibited in the other classes of immune cells. High infiltration of the joint by autoreactive sensitized lymphocytes worsens the patient's condition. Apoptosis inhibition is especially noticeable in the early stages of RA and correlates with the concentration of the anti-apoptotic molecule Bcl-2 in the synovia. Activating the apoptotic destruction of lymphocytes (by drug action) allows a positive therapeutic effect and sustained remission. However, it should be noted that genetic factors play a significant role in the onset, progression and drug response of RA. In addition, environmental and behavioral factors can activate RA progression and influence treatment efficacy.

Pulse fire extinguishing was actively developing. There is a wide range of impulse fire extinguishing devices on the market. However, existing standards do not cover the entire class of these products. Hence there are problems with their certification. To date, two standards are approved and in force: GOST R 53291—2009 «Fire-fighting equipment. Mobile and portable fire extinguishing devices with high-speed delivery of fire extinguishing agent. General technical requirements. Test methods», and GOST R 53286—2009 «Fire-fighting equipment. Automatic powder fire-extinguishing installations. Modules. General technical requirements. Test methods». Two more standards are under development: one of them is essentially a slightly modified version of GOST R 53291—2009 — it will be given the status of interstate; the second supplements GOST R 53286—2009 and concerns installations and modules for gas-powder fire extinguishing. Impulse fire extinguishing installations with self-foaming gas-aerosol-filled foam are not subject to the listed standards for technical requirements and test methods. This applies primarily to the requirements for the volume of vessels used to obtain foam and displace it from there, as well as for the operating time of the pulse fire extinguishing installation, measuring the rate of exit of the fire extinguishing agent, calculating this rate according to the graph of pressure change in the vessel, etc. Therefore, for these installations a separate standard is required. In this case, in general, it is required to give clear definitions of what is meant by impulse fire extinguishing and impulse fire extinguishing installations.

The article deals with the problems of conducting periodic inspections of equipment. This is due to the high frequency of equipment shutdown for its technical diagnostics and examination in accordance with the requirements of regulatory and technical documentation, in particular the Federal norms and rules «Rules for the safe operation of process pipelines». It is noted that the inspection is an important tool for ensuring the integrity of the equipment and, as a result, the industrial safety of the facility. At the same time, it is indicated that the inspection can be implemented on the basis of one of two approaches: regulated and risk-oriented. A general description of the inspection methodology, taking into account risk factors, is presented. It is pointed out that a risk-based approach to inspections is widespread in a number of countries. Various methods of implementing this approach are given, taking into account a large number of standards. The basics of API 581 3rd Edition and S-RBI techniques used for inspections are described. The technological process of the gas condensate stabilization system of a plant for the production of liquefied natural gas is described. A process pipeline is considered as an object of the study, for which an inspection interval is determined using the API 581 3rd Edition methodology. At the first stage of determining the inspection interval according to the S-RBI methodology, the process of assessing the criticality of the failure is described. The second step describes the process of determining the confidence factor, where the focus is on the estimation of the uncertainty in predicting the corrosion rate. At the third stage, the coefficient of the inspection interval is determined based on the data on the criticality of the failure and the reliability factor. Then an example of calculating the inspection interval for the object under study is given. Based on the results obtained, a conclusion was made about the comparability of API 581 3rd Edition and S-RBI methods. Both methods have their advantages and disadvantages, but at the same time they provide optimization of the scope of inspection work while maintaining a high level of industrial safety of the facility. In order to improve production efficiency, reliability and safety of pressure equipment, and optimize inspection intervals (which will allow to reduce the financial costs of enterprises), it is advisable to apply the above practices in the Russian Federation, providing the required legal and regulatory framework.

In 2015, the UN General Assembly defined sustainable development goals for the next fifteen years. Their achievement can be facilitated by the financing of social programs — activities aimed at improving working conditions, increasing the responsibility of producers for the negative impact on the environment. In today economic conditions, individual manufacturing enterprises are reducing funding for these areas of work. However, cost savings due to cuts in the financing of social programs inevitably leads to an increase in the number of accidents, environmental pollution, an increase in occupational injuries and morbidity of employees, deterioration of their psycho-emotional state and as a result turns into significant costs for the enterprise in the form of loss of working time, reduction in the volume of products produced, image reduction. Analysis of the implementation of social programs by various enterprises shows that stable financing of social activities contributes to a significant improvement in the economic performance of work of these enterprises.

Calculation and subsequent analysis of reliability indicators is a mandatory stage of development and commissioning of technical devices. There has been carried out an assessment of reliability in relation to diesel generator sets operating in the mode of adjustable rotational speed at shared loads, which ensures their high energy efficiency. Unconditional compliance with the requirements for the quality of the generated energy (amplitude and frequency of the voltage in the ship's network) is realized in these generating devices by means of semiconductor converter technology. It is obvious that the increased technical complexity of variable-speed generator sets, which can be attributed to the class of machine-valve generator complexes, is associated with a certain decrease in their reliability indicators. There are presented structural schemes and indicated the composition of power equipment and controls for machine-valve generator complexes based on asynchronous generators with a short-circuited and phase rotor. The method of calculating the reliability indicators of these asynchronous diesel generator complexes is considered. The results of calculating the failure rate and operating time for failure are given, taking into account the load diagram of the power plant and the tachogram of the drive internal combustion engine, which corresponds to operation at energy-efficient rotational speeds at optimal (close to nominal) specific fuel consumption. The results of a comparative analysis of the operating time for failure allow us to determine the most reliable version of asynchronous generator electrical installation in operation.

Malaysia is one of the countries where celebrities are commonly featured in advertisements to promote products to consumers through traditional and social media platforms. In this digital age, scholars are debating about whether celebrity endorsement can translate to effective advertising. Religion has become a significant factor because it can lead to a desire for responsible consumption. In the context of consumerism, religiosity can facilitate Muslim consumers' purchasing decisions since Islam encourages its adherents to follow Sharia values as a way of life. Based on a survey of 300 Muslim consumers, the findings revealed that religiosity moderates the positive effect of celebrity endorsement on advertising effectiveness. Specifically, the impact of celebrity endorsement on advertising effectiveness is greater when the religiosity level is high rather than low. From the practical standpoint, marketers should prioritise the celebrity selection process to comply with the teachings of Islam.

This study aims to identify the key factors affecting the auditors’ performance. Through the lens of the Behavioral Decision Theory (BDT) framework, this study examines the direct effects of audit competency, situational support and information search factors in enhancing auditors’ performance. A survey was conducted on audit firms of varying sizes in Malaysia. The data were collected and were analyzed using Structural Equation Modelling-Partial Least Square (SEM-PLS) statistical tools. Based on evidence from external auditors, the results indicate that audit competency, situational supports and information search are important in the efficiency and effectiveness of auditors’ performance. This study has several contributions to the literature.

This empirical investigation has aimed at exploring the impact of climate change vulnerability, governance, and oil rent on sustainable development in Saudi Arabia, for the period 1998 to 2019. The econometric analysis uses OLS regressions, and various findings have emerged. Climate change vulnerability positively influences sustainable development, which can be attributed to the continuous adaptation and mitigation efforts to tackle the country's harrowing effects of climate change. Likewise, oil rents report a favourable impact on sustainable development, implying the Kingdom’s efforts to balance the adverse consequences of fossil fuel dependency on environmental quality. In contrast, the governance score is negative; hence, the composite effect on sustainable development is nefarious, although the result is statistically not significant. Furthermore, health expenditure per capita positively influences sustainable development, but the result is statistically insignificant. Moreover, the analyses also show tgrowth development, proxied by GDP, has been negatively impacting sustainable development. Lastly, FDI is found to be harmful to sustainable development in the case of Saudi Arabia. The study recommends ongoing investments towards climate change policymaking and development, and triggers strident calls for economic diversification of moving assets towards “greener” sectors. Similarly, the health care sector requires a revamp in quality and delivery s to contribute more effectively towards sustainable development. Most importantly, the governance structure and quality of institutions in Saudi Arabia require a profound transformation, so that good governance and efficient public administration become key players in the advancement of the Saudi Vision 2030 agenda, otherwise, the ambitions of the Kingdom might reach to a standstill.

The purpose of this paper is to estimate the market risk exposure within the Tiger Cub Economies regions in calm and stormy market conditions. The secondary objective of the empirical research is to determine the reliability and accuracy of the market risk model used by most banking sectors within the region as the primary tool for mitigating potential systematic risk. The precision of the market risk model was assessed using the 250-day trading data of major indices from five emerging ASEAN countries or known as the Tiger Cub Economies stretching from January 2018 until December 2021. It consists of two sub-samples which are known as before and during the pandemic COVID-19. The current study contributes to the existing literature on the ability of the VaR-HS model in estimating accurate market risk exposure in light of the recent pandemic COVID19 within the Tiger Cub Economies region. Interestingly, it is also evident that inaccurate VaR-HS tend to overestimate the risk and VaR-GARCH tends to severely underestimate the measures during extreme market conditions. Finally, by recalibrating models that severely over/understate the risk during pandemic stormy market conditions in SETi and VNI indices, it is also imperative that RiskMetrics EWMA could improve the estimation measures in an extreme market event by putting more weights on the most recent volatility memory. The current study reveals new insights where in the event of a crisis, HS-VaR estimates tend to be overstated while GARCH-VaR measures could be understated where it is evident that EWMA-VaR estimates could provide a better measure of market risk exposure, particularly during stormy periods.
Analyzing the profitability determinants of financial institutions: Evidence from East Asians countries

Starting around 1960, Asia, the biggest and the most crowded place on the planet, has become wealthier compared to the rest of the world. Such growth and development definitely have not happened to other countries at a similar speed all around the continent. The western region of Asia has developed at a similar pace as the remainder of the world. However, the eastern region has grown to an unmatched level. With this in mind, this study aims to investigate the factors that determine and influence the profitability of the financial institution in East Asia. Panel data of eight East Asian countries were selected for the time frame between 2002 to 2021. Analysis of various factors that play an important role in altering the financial institution’s profitability level was performed. These factors include the net interest margin, capital total assets, cost to income, non-performing loans, bank stability, the gross domestic product, and liquidity. The results displayed distinctive values. First, factors such as capital total assets, the stability of the bank, and gross domestic product revealed a significant influence on the net interest margin. Additionally, liquidity, the cost of income, non-performing loans, and the gross domestic product presented a decrease in the level of net interest margin. This is acceptable for the liquidity and non-performing loans since they have an inverse relationship with the net interest margin. On the other hand, a 1% increase in the capital total asset and the stability of the bank has enlarged the net interest margin by 0.05% and 0.04% successively. Hence, the results of this study may be valuable for other countries to consider in efforts to reshape their financial sector and monetary efficiency. The discoveries may also contribute significantly to the existing literature in this area since there is limited investigation concerning the East Asian region’s financial sector.

Remaja merupakan generasi berkelanjutan yang dapat membangun bangsa dimana remaja yang sehat secara fisik dan mental dengan memiliki pengetahuan kesehatan mental akan mampu menghadapi perubahan zaman. Namun, pada kenyataannya dalam hal literasi kesehatan mental banyak diantaranya yang masih belum mendapatkan pengetahuan itu. Literasi kesehatan mental dapat ditinjau dari kepribadian seseorang. Kepribadian dapat diukur dengan Big Five personality traits, yang terdiri dari extraversion, agreeableness, conscientiousness, negative emotionality dan open-mindedness. Penelitian ini bertujuan untuk melihat pengaruh Big Five personality traits terhadap mental health literacy pada remaja di Yogyakarta. Subjek penelitian terdiri dari 200 siswa berusia 13–18 tahun dan berdomisili di Yogyakarta. Alat ukur yang digunakan adalah Mental Health Literacy Scale (MHLS) dan Big Five Inventory. Analisis data menggunakan uji analisis regresi berganda dan uji korelasional antarvariabel. Hasil extraversion trait memiliki korelasi positif yang signifikan dengan literasi kesehatan mental (r = .01, p < .05), sedangkan negative emotionality trait memiliki korelasi negatif yang signifikan dengan literasi kesehatan mental (r = - .015, p < .05). Hasil penelitian menunjukkan bahwa Big Five personality traits menjadi prediktor literasi kesehatan mental. Extraversion trait (β = .219, p < .05) merupakan prediktor yang lebih kuat dibandingkan dengan trait kepribadian lainnya.

Pandemi Covid-19 tahun 2020—2022 memberikan banyak dampak pada sektor pendidikan, salah satunya adalah mengubah metode pembelajaran menjadi metode pembelajaran jarak jauh (PJJ). Setelah kurang lebih setahun berjalan sejak awal masa pandemi yaitu pada tahun 2021), implementasi PJJ ternyata banyak menimbulkan dampak negatif sehingga pemerintah mengubahnya menjadi pembelajaran tatap muka terbatas (PTM-T). Salah satu faktor terpenting dalam implementasi perubahan adalah mempersiapkan guru sebagai penggerak dalam pembelajaran, terlebih pada guru sekolah dasar. Penelitian ini dilakukan untuk mendapatkan gambaran readiness for change guru sekolah dasar di Jabodetabek terkait perubahan dari PJJ ke PTM-T pada tahun 2022. Pendekatan yang digunakan dalam penelitian ini adalah mixed methods. Data kuantitatif diperoleh melalui kuesioner readiness for change (RFC) yang dianalisis menggunakan teknik statistik Kruskal-Wallis untuk uji beda dimensi RFC, dan Mann-Whitney untuk menganalisis data demografis. Data kualitatif diperoleh melalui wawancara yang dilakukan kepada guru di Sekolah X. Hasil penelitian menunjukkan bahwa readiness for change berada pada kategori tinggi, yang artinya para guru memiliki kesiapan yang baik dalam menghadapi perubahan dari PJJ ke PTM-T. Meskipun secara keseluruhan readiness for change para guru berada pada tingkat yang tinggi, namun tingkatan per dimensinya berada pada kategori rendah, sedang, dan tinggi.

Published: August 2023

O presente trabalho tem por objetivo a análise da possibilidade de aplicação do princípio da insignificância no delito de porte de drogas para consumo pessoal (art. 28, da lei 11.343/2006). Dessa forma, visa-se interligar os princípios da lesividade, da liberdade, da proporcionalidade em consonância com precedentes do Superior Tribunal de Justiça e Supremo Tribunal Federal para elucidar os posicionamentos e fundamentos adotados frente à sua possível aplicação. Enquanto parte da doutrina/jurisprudência entende que o princípio da insignificância não se aplica ao uso e tráfico de drogas, por se tratarem de crimes cujo o sujeito passivo é a saúde pública, considerado crime de perigo abstrato, o que torna irrelevante a quantidade da substância apreendida, a outra parte defende que sua inaplicabilidade implica frontal violação do princípio da ofensividade, dogma garantista prevista no inciso XXXV do artigo 5º da Constituição Federal. Neste artigo utiliza-se   como   método   de abordagem, o dedutivo e como método de procedimento, o bibliográfico e o jurisprudencial.
