Almost lossless compression of noisy images
Authors: Jähne Bernd 
Published: May 2023

Abstract
An almost lossless compression method for images is introduced adapted to the temporal noise of image sensors. In a first step, a non-linear gray value transform is applied to generate an image with a gray value independent temporal noise and less bits than the original image. The chosen value for the standard deviation of the temporal noise in the transformed image determines how accurately mean values and the standard deviation of temporal noise can be computed and to which extent the image can be compressed further by a lossless compression in a second step. Just a measurement of the noise characteristics according to the open and international EMVA standard 1288, a non-linear gray value transform for noise equalization, and an open source lossless compression algorithm are required to use this new compression method.
Stress-induced severe transient hypercortisolism with reversible bilateral adrenal enlargement after cardiogenic shock

Published: May 2023

Summary
Acute illness-related stress can result in severe hypercortisolism and bilateral adrenal enlargement in certain patients. We report a case of stress-induced hypercortisolism and bilateral adrenal enlargement in a patient admitted for acute respiratory distress and cardiogenic shock. Bilateral adrenal enlargement and hypercortisolism found during hospitalization for acute illness resolved 3 weeks later following the resolution of acute illness. Acute illness can be a precipitating factor for stress-induced hypercortisolism and bilateral adrenal enlargement. We hypothesize that increased adrenocorticotrophic hormone mediated by corticotrophin-releasing hormone from physical stress resulted in significant adrenal hyperplasia and hypercortisolism. This mechanism is downregulated once acute illness resolves.

Learning points

Adrenal enlargement with abnormal adrenal function after stress is uncommon in humans; however, if present, it can have self-resolution after the acute illness is resolved.

Stress induces enlargement of the adrenals, and the degree of cortisol elevation could be very massive. This process is acute, and the absence of cushingoid features is expected.

Treatment efforts should be focused on treating the underlying condition.
Central serous chorioretinopathy secondary to intramuscular testosterone therapy

Published: May 2023

Summary
A patient treated with intramuscular testosterone replacement therapy for primary hypogonadism developed blurred vision shortly after receiving his testosterone injection. The symptom resolved over subsequent weeks and recurred after his next injection. A diagnosis of central serous chorioretinopathy (CSR) was confirmed following ophthalmology review. A decision was made to change the patient’s testosterone regime from this 12-weekly intramuscular injection to a daily topical testosterone gel, given the possibility that peak blood levels of testosterone following intramuscular injection were causing his ocular complaint. His CSR did not recur after this change in treatment. CSR secondary to testosterone therapy is a rare finding but has been reported previously in the literature.

Learning Points

Blurred vision in patients treated with testosterone replacement therapy (TRT) should prompt an ophthalmology review.

The potential for reduced risk of central serous chorioretinopathy (CSR) with daily transdermal testosterone remains a matter of conjecture.

CSR is a rare potential side effect of TRT.

Introducción. La normativa que regula los alimentos balanceados asegura el bienestar de las mascotas, la salud pública y la seguridad al consumidor, por lo que es valioso corroborar el contenido de los nutrimentos declarados en las etiquetas. Objetivo. Determinar el cumplimiento del análisis de garantía de 34 alimentos importados para perros, gatos, hámsters, conejos, peces ornamentales y tortugas, y comparar los resultados con las recomendaciones nutricionales encontradas en la literatura. Materiales y métodos. Durante los meses de agosto y diciembre del año 2018, se obtuvieron muestras de alimento de perros (10), gatos (10), peces ornamentales (5), tortugas (4), hámster (3) y conejos (2); mediante compra directa en diferentes puntos de venta en San José, Costa Rica. Se analizó el contenido de humedad, proteína cruda (PC), extracto etéreo (EE), fibra cruda (FC), calcio, fósforo, sal y carbohidratos. Se calculó el contenido promedio, la desviación estándar, el valor máximo y mínimo de cada nutrimento en cada grupo de alimento, según la especie animal. Los valores individuales y promedios obtenidos se compararon con los valores declarados en la etiqueta y las recomendaciones nutricionales encontradas en la literatura. Resultados. Los nutrimentos que presentaron incumplimientos fueron: sal (27), calcio (16) y energía (14). Además, se encontró que alimentos no declaraban el contenido de sal (14), calcio (9) y fósforo (7). Con respecto a los requerimientos mínimos nutricionales, veintidós alimentos presentaron deficiencias o excesos en al menos un nutrimento [carbohidratos (11) y extracto etéreo (7)]. Conclusiones. Los alimentos balanceados importados para perros, gatos, conejos, hámster, tortugas y peces ornamentales presentaron incumplimientos en los contenidos de PC, EE, FC, EM, Ca, P y sal garantizados en la etiqueta. La composición nutricional de los alimentos evaluados limita el cumplimiento de requerimientos nutricionales de los animales, excepto para conejos que sí se cumple con los requerimientos.

AbstractBackground and aimsADAMTS-4 is a protease enzyme involved in vascular remodeling and atherosclerosis. It was found to be upregulated in macrophages seen in atherosclerotic lesions. This study aimed to investigate the expression and regulation of ADAMTS-4 in oxidized LDL-induced human monocytes/macrophages system.MethodsPeripheral blood mononuclear cells (PBMCs) isolated from human blood, and treated with oxidized LDL (50 μg mL−1) were used as the model system for the study. mRNA and protein expressions were studied by PCR, ELISA, and western blot analysis. ROS production and cell viability were determined by DCFDA staining and MTT assay, respectively.ResultsIn the presence of oxidized LDL, monocytes get differentiated into macrophages, which were confirmed by the increased expression of macrophage differentiation markers and pro-inflammatory cytokine TNF-α. Oxidized LDL increased the mRNA and protein expression of ADAMTS-4 in monocytes/macrophages. N- Acetyl cysteine, ROS scavenger, downregulate the protein expression of ADAMTS-4. The expression of ADAMTS-4 was decreased significantly in the presence of NF-κB inhibitors. SIRT-1 activity was significantly downregulated in the macrophages and was reversed in the presence of the SIRT-1 agonist, resveratrol. Acetylation of NF-κB and hence the expression of ADAMTS-4 were significantly downregulated in the presence of SIRT-1 activator, resveratrol.ConclusionsOur study suggests that oxidized LDL significantly upregulated the expression of ADAMTS-4 in the monocytes/macrophages through ROS- NF-κB- SIRT-1 pathway.

Introduction. The pandemic of a novel coronavirus infection has demonstrated the importance of assessing the ADAMTS-13/vWF axis in patients with COVID-19, because a decline in this ratio mirrors disease severity. However very few data in the global literature on crosstalk and ADAMTS-13/vWF levels in pregnant women remaining very contradictory are available. Taking into consideration an impact of the ADAMTS-13/vWF axis on prevalence of thrombosis and disorders in the hemostasis system, investigation of this issue is highly demanded.Aim: to assess the functioning of the ADAMTS-13/vWF axis during physiological pregnancy.Materials and Methods. A controlled non-randomized study was conducted: main group included 44 women with physiologically occurring pregnancies at I, II and III trimesters; the control group consisted of 45 healthy non-pregnant women. The plasma level of ADAMTS-13 inhibitor (ADAMTS-13:i), ADAMTS-13 antigen (ADAMTS-13:Ag), vWF antigen (vWF:Ag), and ADAMTS-13 activity (ADAMTS-13:Ac) as well as relevant ratio (ADAMTS-13:Ac/vWF:Ag) were measured.Results. It was shown that in parallel with increasing gestational age, significant changes occurred in the ADAMTS-13:Ac/vWF:Ag ratio. In main group, patients at II trimester were found to have level of ADAMTS-13:Ac/vWF:Ag 0.359 ± 0.121, in III trimester –0.253 ± 0.741, which significantly differed (p < 0.01) compared to control group with non-pregnant women (1,134 ± 0,308).Conclusion. Our study provides new insights into the functioning of the ADAMTS-13:/vWF axis in women with physiologically occurring pregnancy at I, II and III trimesters. Decline in ADAMTS-13:Ac was demonstrated along with increasing vWF:Ag level observed in parallel with increasing gestational age. Apparently, the progressive decrease of ADAMTS-13 concentration during pregnancy is associated with its increased consumption due to high vWF level. However, due to the small single-center patient cohort, further studies with larger-scale studies are needed.

Research subject. Diseases of the oral mucosa occupy a special place in the structure of dental morbidity due to the peculiarities of etiology and pathogenesis, a tendency to relapse, a fairly high degree of malignancy. Currently, they are considered the least studied medical and social problem of dentistry, both in our country and abroad. The objective is to assess the prevalence and structure of diseases of the oral mucosa among workers of the special economic zone of the Republic of Tatarstan. Methodology. To conduct a clinical study, the results of a comprehensive dental examination of 370 employees of the special economic zone "Alabuga" (Republic of Tatarstan, Yelabuga district) aged 22–58 years were used. The diagnosis of pathology of the oral mucosa in compliance with oncological alertness was carried out by the method of luminescent diagnostics using the OLDD-01 emitter. Statistical linear regression analysis of the data and interpretation of the results obtained were performed using IBM computer software and the SPSS software package (PASW Statistics 20). Results. In 18.7 ± 1.2% of the examined persons of the industrial enterprise, in the structure of diseases of the oral mucosa, in 8.2% of cases, chronic fissure of the vermilion border (p < 0.1) and angular cheilitis (p < 0.1) prevailed, in 2.8% oral thrush (p < 0.05), in 2.5%	benign migratory glossitis (p < 0.05), in 2.2% other forms of stomatitis (p < 0.1), in 1.9% leukokeratosis (p < 0.1). As a result of the introduction of a complex of therapeutic and preventive measures, the prevalence of lesions of the oral mucosa decreased after 6 months by an average of 1.6 times (12.7%), after 12 months by 2.7 times (7.0%) and after 18 months by almost 4.7 times (4.2%). Conclusions. Thus, the use of data obtained among employees of industrial enterprises makes it possible to study the prevalence of pathology of the oral mucosa, as well as to plan the effectiveness of medical and preventive measures provided. The conduct of this study contributes to the modernization of dental medical care for employees of industrial enterprises of the special economic zone.
Tourism and hospitality management faculty satisfaction towards flexible learning: A cross-sectional survey from higher educational institutions in Central Luzon, Philippines
Authors: Miranda John Paul , Cruz Maria Anna D. 
Published: May 2023

The present study aimed to assess faculty satisfaction on the delivery of tourism and hospitality management programs in the flexible learning mode at the onset of the COVID-19 pandemic. It employed a purposive sampling design where 85 Tourism and Hospitality Management (THM) faculty members, across 27 Higher Education Institutions (HEIs) in the Central Luzon, Philippines, participated. While findings indicate that the faculty members are generally satisfied with the conduct of flexible learning in their institutions, they generally agree on items relating to having higher workloads, longer preparation time for a course, lack of human interaction by not seeing students face-to-face, lower participation of students, technical and connectivity problems, and the need to employ creativity and resourcefulness in the development of learning aids. As the better normal ushers in, flexible learning will still be implemented with the addition of limited face-to-face delivery. As such, faculty members play a vital role in the success of program delivery. That is, when they are satisfied with their conditions, students perform better which leads to better learning and outcome. Effective institutional support services are thus key to ensuring quality flexible learning environments. For continuous improvement, recommended actions should constantly be reviewed, modified, and enhanced to respond to uncertainties and the changing times. HEIs need to recalibrate their curriculum grounded on a deeper understanding of flexible learning to address these challenges; capacitate the faculty with innovations available to enhance student engagement; upgrade infrastructure designed to provide timely feedback and to ease out connectivity issues; and lastly, review policies on faculty workload and number of preparations to consider longer preparation time.

The assessment of service quality effect in higher education sector on satisfaction, suggestion, and behavioral intention of university students: The case of Turkey
Authors: Gürbüz Esen , Bayraktar Muhammet 
Published: May 2023

The number of enterprises in the service sector is increasing with the time and the market for service sector is expanding. Universities as higher education institutions were affected by these developments in the service sector and have included providing quality service to their internal and external stakeholders as their top priority. Providing quality service in a university affects the satisfaction of students, who are among the most important stakeholders, their intention to suggest university to potential students and to visit after graduation. Hedperf scale was used to measure the service quality at universities and various institutions in different countries. The construct validity of the Hedperf scale was investigated according to the student perceptions at a university in Turkey and it was found with exploratory factor analysis (EFA) that service quality dimensions were classified into four dimensions - academic, non-academic, reputation, and access. Among these dimensions, the effect of academic, reputation and access dimensions on satisfaction, suggestion, and behavioral intention for visiting after graduation was determined, while the effect of non-academic dimension was not determined. Service quality dimensions explain approximately 31% of the variability in overall satisfaction. Access affects satisfaction at the level of β = .322, which is more than other dimensions. It was determined that the service quality dimensions explained 17% of the behavioral intention to “visit the university after graduation” and the effect of access (β = .264) among these dimensions was higher than the other dimensions. University service quality dimensions explain 23% of the intention for “suggest the university to potential students”, and it was determined that the reputation dimension has the strongest effect (β = .367). The research explores the link between service quality and satisfaction, suggestion, behavioral intention and determines the construct validity of the scale developed in a foreign culture.

Authors: Ridwani Ahmad Ansor , Mukhibat  
Published: May 2023

Fenomena Covid-19 sangat berimbas besar dalam dunia pendidikan di Indonesia. Dengan tidak adanya interaksi antar warga sekolah, secara tidak langsung budaya mutu sekolah terganggu dan bahkan terhenti karena budaya mutu sekolah secara umum membutuhkan interaksi antar warga sekolah. Jika budaya mutu sekolah terganggu, maka kualitas sekolah juga akan berpengaruh. Agar kualitas mutu sekolah tetap terjamin, maka perlu adanya inovasi dalam pelaksanaan budaya mutu sekolah. Strategi operant conditioning menjadi salah satu solusi dari permasalahan keterbatasan waktu dan interaksi pada budaya mutu sekolah dimasa pandemi. Adapun tujuan dari penelitian ini yaitu untuk mendeskripsikan: (1) strategi operant conditioning dalam budaya mutu sekolah. (2) implemetasi operant conditioning dalam budaya mutu sekolah. Metode yang digunakan dalam penelitian ini adalah metode kualitatif deskriptif. Teknik pengumpulan data berupa wawancara, observasi, dan dokumentasi. Berdasarkan hasil penelitian menunjukkan bahwa: (1) Operant conditioning dalam budaya mutu sekolah dapat menggunakan beberapa strategi antara lain: penerapan kebijakan, dan penggunaan sistem online. Penerapan kebijakan dapat menggunakan beberapa hal antara lain: penggunakan SOP, pembiasaan New Normal, dan perubahan sistem pembelajaran. Penggunaan sistem online dapat dilakukan dengan beberapa tindakan antara lain: penggunaan platform Whatsapp sebagai media interaksi dan sarana pendekatan emosional, penggunaan situs Masterweb sebagai inovasi dalam pelaksanaan budaya sekolah. (2) Implementasi inovasi operant conditioning dalam budaya mutu sekolah dapat menggunakan 4 sistem pengondisian yaitu: penguatan positif (positif reinforcement), penguatan negatif (negatif reinforcement), hukuman negatif (negative punishment), hukuman positif (positif punishment). Semua memiliki dampak positif yang ditimbulkan antara lain: meningkatkan nilai religius, nasionalis, cinta lingkungan, sopan santun dan disiplin.
