Published: October 2023

In China, there is a lack of data regarding the awareness and treatment preferences among patients with vitiligo and their families. To address this gap, a cross-sectional questionnaire-based study was conducted to investigate disease awareness and treatment preferences in Chinese patients with vitiligo. The study also evaluated willingness to pay, using 2 standardized items, and assessed quality of life, using the Dermatology Life Quality Index (DLQI) score. Data from 307 patients with vitiligo (59.3% women, mean age 28.98 years, range 2–73 years) were analysed. Of these patients, 44.7% had insufficient knowledge of vitiligo, particularly those from rural areas or with low levels of education. Mean DLQI total score was 4.86 (5.24 for women and 4.30 for men). Among the most accepted treatments were topical drugs, phototherapy, and systemic therapy. Patients were relatively conservative about the duration and cost of treatment, with only 27.7% willing to pay more than 10,000 Chinese yuan renminbi (CNY) for complete disease remission. High level of education, high income, skin lesions in specific areas, and skin transplantation therapy predicted higher willingness to pay. Insufficient knowledge was associated with a higher burden of disease. In order to reduce the disease burden and improve treatment adherence it is crucial to enhance disease awareness and take into account patient preferences.

Authors: Hovland Honerud Jon , Opsahl André , Fauskanger Eivind
Published: October 2023

Artikkelen oppsummerer forfatternes funn og erfaringer ved bruk av spillbasert undervisning i bedriftsøkonomiske emner i perioden 2020–2022. Formålet med prosjektet har vært å undersøke hvordan simuleringsverktøy kan brukes i undervisningen, samt måle og vurdere kognitive og affektive virkninger. I perioden har vi testet ut ulike måter å integrere spillbasert læring i undervisningen på samt gjennomført ulike typer datainnsamling. Vi finner ingen klare indikasjoner på kognitiv effekt målt ved kunnskapstester og karakter. På den annen side rapporterer studentene selv om økt «lavkognitiv » læring i form av grunnleggende forståelse av konsepter og begreper. Vi registrerer også en klar positiv effekt på motivasjon hos majoriteten av studentene. Artikkelen vurderer funnene i lys av tidligere forskning, og oppsummerer våre erfaringer i fem anbefalinger til studenter og lærere som vurderer implementering av spillbasert undervisning.

Published: October 2023

Fertilization, an important phase of reproduction, is physiologically the union of the male and female gamete. This succession involves the fusion of an oocyte with a sperm, leading to generation of a single diploid cell, the zygote, from which a new individual organism develops. The elucidation of the physiological, biochemical and molecular mechanisms of fertilization has enthralled researchers of relevance for several years. This editorial embodies this fascinating succession at physiological, biochemical and molecular level.
Comparative Biochemical Effects of Natural and Synthetic Pesticides on Preserved Vigna Subterranea in Male Albino Rats
Authors: Yunusa Rahima
Published: October 2023

Preservatives both natural and synthetic have been widely used to store food in order to ensure all season availability and safety for human consumption. This study was carried out to evaluate the biochemical effects of natural and synthetic pesticides preserved Vigna subterranea in male albino rats. Thirty six adult male albino weighing between 150 – 200 g were randomly allocated into 6 groups A, B, C, D, E and F (n=6 each). Vigna subterranea were preserved for six months in 5 air tight containers: preserved with neem ash, Pepper, Dichlovors, Aluminium Phosphide and without preservative. The preserved beans were milled into powder and used as dietary supplement for the rats. All the animals freely received animal feed and water. Group A, B, C, D, E and F were fed with animal feed and water only, Vigna subterranea without preservative, neem Ash preserved Vigna subterranea, Pepper preserved Vigna subterranea, Dichlovors preserved Vigna subterranea and Aluminium Phosphide preserved Vigna subterranea respectively. The dietary intervention lasted for 2 months after which the animals were sacrificed. The blood sample of each rat was collected and analyzed using standard methods. The results from the analysis of the liver function across the groups with preservatives showed increase in liver enzymes. The serum AST shows significant increase (p < 0.05) in Group D compared to Group A. ALT significantly (p < 0.05) increased in all the test groups except the group fed with pepper compared to the control which indicates there may be possible injury to the liver. The result showed elevation (p < 0.05) of C-reactive protein in all the test group compared to Group A and significantly (p < 0.05) reduced in the group fed with neem Ash, which may indicate injury and inflammation in the test animals of the other preservatives. In the kidney, the serum urea findings showed significant increase (p<0.05) in all the groups fed with preservatives compared to the Group A and the concentrations of Creatinine increased significantly (p<0.05) in all the groups fed with the preserved V. subterranea compared to the control indicating there may be possible damage to the kidney. A significant decrease (p<0.05) in the antioxidants-CAT, SOD and GPx and increase (p<0.05) in MDA in the group fed with preservatives indicates there may be increase in lipid peroxidation, leading to oxidative stress and cell injury in the test animals. The results of this study suggest that the use of some of these preservatives which could be natural and synthetic may be toxic and could lead to cellular and tissue damage.

Published: October 2023

This study evaluated the effects of ethanolic extracts of fruits of Dennettia tripetala on liver function of male albino rats. Dennettia tripetala is an endemic plant of west tropical Africa that is known as pepper fruit. The fruit is known for its numerous medicinal properties such as antioxidant, anti-inflammatory and antidiarrhea. The plant materials were air dried and made into powder, 250g was used for the crude extraction using 70% ethanol. Ninety eight male albino rats were used in this study; forty eight were used for LD50 and fifty for the main experiment. The animals were randomly distributed into 5 groups of 10 animals each. The test animals were administered single dose of ethanolic extracts of fruits of D. tripetala (200 mg/kg and 400 mg/kg) daily for twenty-one days. The animals sacrificed at end of the 21 days. Blood sample was collected via cardiac puncture for biochemical analysis, while the liver was harvested for histological examination. A very high LD50 value of 4000 mg/kg body weight was recorded in this study. The results of biochemical parameters revealed that mean values of AST ALT and ALP were elevated significantly (p<0.05) in all the test groups, except ALP in group 4 which showed no significant alteration when compared to the control. Total protein, albumin and globulin showed no significant alteration in all the test groups; total and direct bilirubin decreased significantly in test groups 4 and 5, and increased in group 2, while indirect bilirubin showed no significant alteration in all the test groups. Photomicrograph of liver section of normal control rats (group 1) showed normal central vein, portal triad, sinusoids and lamella of hepatic cells as well as those in all the test groups.
Fibrinogen-Related Protein, Fgl2, of Hamster Cauda Epididymal Fluid: Enzymatic Characterization, and Identification of Fgl2- Binding Proteins and Ligand of Defective Hamster Sperm Organelles
Authors: K Nagdas Subir
Published: October 2023

The luminal environment of the mammalian epididymidis performs a dual function; sperm maturation and maintaining sperm viability. We previously identified a secretory protein (260/280KDa oligomers) of hamster cauda epididymal principal cells that binds to nonviable sperm. The 260/280KDa oligomers are composed of 64kDa FGL2 (fibrinogen-like protein-2) and 33kDa FGL1) (fibrinogen-like protein-1). The potential mechanism by which FGL2 binds to degenerative sperm is not clearly demonstrated. In this study, we report the downstream sequence of prothrombinase activity of FGL2, the identification of organelles, and characterize candidate proteins that bind FGL2. The following reaction sequence confirms that FGL2 is a phospholipid-activated serine protease; the conversion of prothrombin to thrombin by FGL2, followed by the conversion of soluble fibrinogen to insoluble fibrin polymers by thrombin. FGL2 binds intensely to tails than heads of de-membranated sperm. A spectrum of polypeptides of cauda sperm tails binds to FGL2. Proteomic analyses of 65KDa, 16kDa, and 13kDa polypeptides of tails correspond to a-Kinase anchor protein 4, glutathione peroxidase 4, and cytochrome c oxidase subunit 4, respectively. Annexin V, a calcium-dependent phosphatidylserine-binding protein localized to the flagellum and co-precipitated with FGL2. We have demonstrated a novel protective mechanism for recognizing and eliminating defective spermatozoa from viable sperm population.

Religious tolerance (between Islam, Christian, Hindu) and multiculturalism is a special value in Balun Village, East Java. Religious inclusiveness does not only occur at the social life, but down to the family level. In Balun family, it is normal to have interfaith marriage. By using in-depth interviews and involved observations, this research is able to reveal that the tolerance value derives from the characteristics of rural communities that tend to place religion as a social religion. The sacredness of religion adapt with the existing traditions that is still be the most important control, rather than religion. The history of religious heterogeneity in Balun also gives an important role to the harmony. This research attempts to explain the potentials and challenges to develop multi-religious tourism and describe the appropriate strategy. A living lab approach that focusing attention to the user identified to be the best. In the living lab, experts and academics role to be the brokers and systems designers, stakeholders and potential local communities are regulators and executors, and the public directly involving in the development project as the evaluators. By utilizing social media, the development of a multi-religious tourism in Balun is possible action in the midst of the pandemic. Providing a platform or website as an alternative solution for virtual tourism is a genious offer for the development of Sustainable Development Goals (SDGs).
ECOLOGICAL BIOSEMIOSIS: A BIOSEMIOTIC READING OF CULTURE AND NATURE RELATIONSHIPS IN THE SELECTED POEMS FROM A NATIVE CLEARING AND MAN OF EARTH
Authors: Ledesma Jan Raen Carlo M. , Pascual Chuckberry J.
Published: October 2023

This paper attempts to flesh out how the biophiliac, anthropocentric, and ethnological modes of biosemiotic representation aid in the imaging and discoursing of nature-culture relationships in the selected poems from the anthologies A Man of Earth and A Native Clearing. Capitalizing on ecocriticism, biosemiotics provide an ecological reading of the manifestations of human culture and their natural surroundings. This reading underscores how meaning-making and the intricacies of the sign system transpire in all living systems. This reading also paves the way for modeling the environment through literature highlighting the complex relations between the environment and human culture with an amplified and specialized view of the individual entities that shape and affect the environment. Using the descriptive-analytical research design and the theories of Zapf, Hoffmeyer, and Uexkull, we illustrate how the biosemiotic foregrounds of the poems speak of how sign relations project the dealings and ruptures between human-cultural activities and other natural semiotic subjects. We also underscore the perils stemming from anthropocentric players with emphasis on their cultural undertakings, the hallowed character of nature steering tragic ecology, the evolutionary fitness and adaptability of animals, ecosophy and speciesism and how these affect the biosphere and the formation of biosemiotic linkages and reciprocations.
Correlation of ZnO Surface Morphology and Sensing Performance of EGFET Nitrate Sensor
Authors: Abdullah W. F. H.
Published: October 2023

Zinc oxide (ZnO) sensing electrode (SE) for extended gate field-effect transistor (EGFET) nitrate sensor was deposited on top of indium tin oxide (ITO) substrate using two different methods which were spin coating and chemical bath deposition (CBD) methods. To investigate the correlation between physical properties and sensing performance based on different growth methods, the deposited samples were characterized on its surface morphology using field emission scanning electron microscopy (FESEM). The ZnO sample deposited using spin coating showed an agglomerated structure while ZnO nanorods (ZnR) were observed on the ITO sample using the CBD method. Before the nitrate sensing measurement, the polyvinylpyrrolidone (PVP) polymer was deposited on top of ZnO samples for both methods at different concentrations of 2, 4 and 6 wt%. Both samples showed the ability as a SE for the EGFET nitrate sensor with 4 wt% PVP showed the optimum sensing behaviour. Based on the results obtained, the sensitivity of the ZnO SE using spin coating and ZnR by CBD method were 3.9 and 59.8 mV/dec, respectively, with the linearity 0.92919 and 0.98414, respectively. It was evident that nitrate sensing performance depended on the SE’s growthmorphology. The high sensitivity of ZnR SE was related to nanorods structure that provides a high surface area and facilitates more contact between SE and nitrate solution for ion adsorptions. As a comparison, a sample without ZnO material with 4 wt% of PVP concentration was deposited and tested for nitrate sensing performance. The sensitivity and linearity of PVP sample were 20.60 mV/dec and 0.76601. It was proven that the ZnO material plays important role in increasing the nitrate sensing performance.
Numerical Analysis of the Effect of Charge Transfer Coefficient (CTC) on Bubble Evolution of Polymer Electrolyte Membrane (PEM) Electrolyzer
Authors: Tijani Alhassan Salami
Published: October 2023

There is a growing concern on the need to enhance the current density of alkaline electrolysis without compromising reduction in efficiency. During the operation of alkaline electrolyzers, a portion of the electrode surface is covered with cloud of bubbles. The bubbles increase ohmic resistance and activation overvoltage of the electrolyte. This study aims to investigate the effect of charge transfer coefficient (CTC) on the voltage characteristics of PEM electrolyzer. Matlab was used to simulate the equations. The simulation result shows that CTC values at the anode electrode range between 0.807 and 1.035. Interestingly, at CTC of 0.5 and 0.2 for anode and cathode, the operating voltage at 1 A/cm2 was observed to be 2.0 V. Also at CTC of 2 and 0.5 for anode and cathode, respectively, there was a significant drop in operating voltage up to 1.62 V with a current density of 1 A/cm2, this accounts for about 27% reduction in operating voltage
Elucidation of rGO Incorporation on Structural, Morphological and Optical Properties of rGO/ZnO Nanocomposites for Flexible Humidity Sensor Applications
Authors: Mamat Mohamad Hafiz
Published: October 2023

The effect on structural, morphological and optical characteristics towards humidity sensing capability was elucidated as humidity-sensitive sensing material that is made by composting zinc oxide nanostructured powder (ZN) nanoparticles with varying capacities of reduced graphene oxide (rGO). The ZN was successfully synthesized through the ultrasonicated solution immersion technique and the rGO/ZN (rZN) nanocomposite sensing material was spread on cellulose substrates employing a simple brush printing technique. XRD, FESEM and UV–Vis Diffuse Reflectance Spectroscopy were utilized to examine the morphological and optical properties of the pristine ZN and rZN nanocomposites. As per the FESEM assessment, ZN nanoparticles with variable sizes were evenly distributed, adhered to, and irregularly positioned on filter paper cellulose fibres. The average reflectance in the visible region declined substantially as the rGO content increased. According to the estimated Urbach energy, the defects in the sensing materials increased as the rGO content increased. The humidity response capability of the nanocomposites exhibits a significant reliance on the quantity of rGO integrated, with the maximum humidity sensitivity achieved for the 1.0 wt.% rGO dosage. At a high operating temperature (85 °C), the humidity sensor based on rZN-1.0% nanocomposite exhibits an amplified humidity sensing response current value. These outcomes indicate that rZN nanocomposites have the potential to operate as a humidity-sensitive sensing material with great sensitivity.
The Effect of rGO On Optical Properties of Neodymium Nanoparticles Doped Tellurite Glass System
Authors: Noorazlan Muhammad
Published: October 2023

Nanomaterials based on graphene have outstanding properties, particularly in terms of optical performance. Using melt-quenching and low-cost spray coating procedures, we effectively generated a series of reduced graphene oxide-coated tellurite glasses doped with neodymium nanoparticles, denoted as rGO-ZBTNd (NPs) glasses. An X-ray diffraction study of glass samples validated the glass system's amorphous structure. FESEM morphological analysis was used to evaluate the appearance of rGO on the glass substrate and revealed the dispersion of rGO. UV-Vis spectroscopy was used to determine different absorption bands. The refractive index value calculated using the Dimitrov and Sakka equation was found to be more than n > 2.000 and in the range of 2.339 to 2.657 when compared to uncoated samples. On the basis of these findings, a new method involving rGO deposited on tellurite glass has been developed to improve the tellurite glass currently utilised in laser applications.

Authors: Dinh-Ngoc Nguyen
Published: October 2023

Machining Carbon Fibre Reinforced Plastics (CFRPs) composites are typically accompanied by the appearance of machining damage which strongly impacts the structural integrity of composite parts during their service lives. Studying the correlation between machining damage and its affected factors has still been an open issue. Hence, it is necessary to do more research. This study focuses on investigating the influences of main process parameters and tool wear phenomenon in terms of machining length on the machining quality which was characterized by the surface roughness criterion, the ten-point max, Rz. A full factorial design of experiments was conducted including three levels of feed speed and two degrees of spindle speed. The results revealed that machining damage was mainly influenced by process parameters at a small machining distance, whereas at a longer machining distance, tool wear had a dominant effect on the machining quality than machining parameters. These findings could provide guidelines for selecting suitable machining parameters to enhance the machining quality of CFRP.
The Influence of Repeated Heat Treatments on The Propagation of Fatigue Cracking of Medium Carburized Steel
Authors: Karash Emad Toma
Published: October 2023

The issue of metal fatigue emerged as one of the major issues in a variety of engineering designs, and the design engineers were forced to take metals' fatigue resistance into account. In this paper, multiple quenching mediums and varied heat treatments were utilized to examine the effects of various heat treatments on the development of fatigue cracking in steel. The model that was carburized, quenched in distilled water and tempered before being quenched once more in distilled water and tempered a second time had the best outcomes, the fewest cycles needed to cause the model to fail, and a correlation between the rate of fatigue crack propagation and the length of the crack, according to the results. Additionally, the analytical findings demonstrated that this model, as opposed to models with fixed stress intensity factors, has a fatigue crack growth rate. The model that was carburized, quenched in coolant, then tempered and quenched again without performing the tempered appearance failed very rapidly. The high rate of the stress intensity factor with fatigue crack propagation is shown by the data analysis. The results show a reduction in the growth amount tendency of fatigue crack in the linear region mode-III.

Authors: Yulisinta Florence , Marta Rustono Farady , Panggabean Hana
Published: October 2023

Background: The influence of technology and media on teachers’ beliefs and self-concepts is substantial. The social identity theory explains how an individual’s perception of themselves as a group member influences their social identity. Purpose: This study aims to examine the analysis of vernacular discourse in public service announcements (PSA) from two perspectives: cultural syncretism and pastiche. Methods: The methodology utilized in this study is vernacular discourse analysis with a critical paradigm-based qualitative approach. The objects of this study were two PSA videos of the Ministry of Education (MOE) Singapore. Results: The vernacular discourse analysis reveals that cultural and social contexts influence teachers’ rhetoric, with sociocultural and linguistic conditions reinforcing educational hegemony in the PSA videos of Singapore. Conclusion: MOE’s PSA videos shape teachers’ social identity by employing persuasive strategies to promote teachers’ roles and self-concepts based on the belief that student and societal success begins with the teacher. Implications: Theoretically, this study implies that media can shape teachers’ social identities. The practical implications of this study are using PSA videos to align the role and self-concept of Indonesian teachers, demonstrating how the noble but less prestigious teaching profession shapes the next generation. Additionally, media can be utilized to enhance the quality of education in Indonesia.
Diegetic and nondiegetic sounds in film scoring of Pengabdi Setan film
Authors: Alam Pandu Watu , Permana Rangga Saptya Mohamad , Indriani Sri Seti
Published: October 2023

Background: This research examines the 2017 film Pengabdi Setan scoring function. Joko Anwar wrote and directed the film Pengabdi Setan, released on September 28, 2017. This film is a remake of a 1980 film of the same name. In this film, the score is essential for visually confirming symbols or incomplete messages. There are two types of sound: diegetic sound and non-diegetic sound. Purpose: This research aims to determine how diegetic and non-diegetic sound were used to create a horror atmosphere in the film Pengabdi Setan. Methods: The authors described the audio analysis results in the form of diegetic and non-diegetic sounds using a qualitative descriptive analysis. Documented assessment and observation were employed as data collection techniques. Results: The results indicate that infrasonic sound (infrasound) and sub-bass frequencies in the form of non-diegetic sounds emotionally impact audiences. The typical frequency is 31 Hz, and although it is inaudible to the human ear, the audience can sense the vibrations of this frequency. This frequency can typically only be perceived as a “chest rumble.” In general, both diegetic and non-diegetic sounds in the film Pengabdi Setan contribute to completing the defective message symbol. The combination of infrasonic sound effects, sub-bass, and musical composition validates the visual messages or symbols. Implications: This research can theoretically serve as a resource for future researchers interested in studying diegetic and non-diegetic sound in film. Directors and cinema sound engineers can use this research to construct diegetic and non-diegetic sound in their films, particularly horror films.

Authors: Costa Gilmarques Agapito , Silva Marcio Fernando da
Published: October 2023

A Teoria da Divulgação postula que as entidades podem optar por divulgar informações de forma obrigatória ou voluntária, abrangendo indicadores financeiros e não financeiros. Neste contexto, o presente estudo procura averiguar a potencial influência das variáveis de desempenho financeiro (nomeadamente, dimensão, endividamento, rentabilidade dos ativos, alavancagem, auditoria e crescimento) na divulgação dos indicadores que constituem o Balanced Scorecard (BSC) no seio da gestão relatórios das agroindústrias brasileiras listadas na B3. Empregando uma abordagem quantitativa e descritiva, a pesquisa emprega análise de conteúdo para examinar os relatórios de gestão de 2011 a 2019, a fim de construir os indicadores de variáveis independentes. Os resultados empíricos revelam uma tendência perceptível para a divulgação de indicadores dentro da perspectiva financeira. Esta faceta representa uma proporção substancial do total de indicadores identificados, cerca de 56,13%. Dentre o espectro das variáveis de desempenho financeiro, vale destacar que apenas o tamanho da empresa apresentou significância estatística ao nível de 1%. Esse resultado significa que a dimensão do porte de uma empresa pode, de fato, influenciar o quanto os indicadores que constituem o BSC se manifestam no âmbito dos relatórios gerenciais. As observações deste estudo corroboram a literatura existente, destacando que as empresas do agronegócio, ao priorizar a apresentação de indicadores financeiros em detrimento de contrapartes não financeiras, adotam um padrão de divulgação caracterizado por discrição, eficiência e expectativas racionais.

Authors: Nădășan Ingrid , Ferencz Loránd , Moldovan Geanina , Ábrám Zoltán , Nădășan Valentin
Published: October 2023

Background and objective: Providing brief advice to stop smoking (BASS) can significantly increase motivation to quit, long-term smoking cessation rates, and substantially impact public health. The study aimed to evaluate knowledge, attitudes, and willingness of community pharmacy staff in Mures County, Romania, to provide BASS to smokers.

Methods: The observational, cross-sectional study included a sample of 96 professionals working in community pharmacies in Mures County, Romania. Data were collected using an online questionnaire. Descriptive statistics were calculated.

Results: Generally, more than 90% of the respondents acknowledged that smoking is addictive, represents a health hazard, and increases the risk of lung and laryngeal cancer, chronic obstructive pulmonary disease, heart attack, and stroke. Up to 70% of the respondents recognized the most common scientifically proven quit medications, such as nicotine replacement therapy, bupropion, and varenicline. Most pharmacists agreed that they should regularly ask the patients about their smoking status and encourage smokers to quit. They also declared they should receive continual education regarding quit services, medications, and techniques. BASS was credited with very high efficacy by 17.1%, high efficacy by 26.8%, and moderate efficacy by 46.3% of the respondents. The most common perceived barriers to providing BASS in community pharmacies were lack of demand from smokers (78.0%), lack of time (73.2%), and lack of educational materials (39.0%). About 70% of the pharmacists received no formal training regarding quit services, but more than 75% were interested in earning such a qualification. About 65% of the respondents estimated they could dedicate 10-15 minutes of their daily working time to provide BASS to interested customers.

Conclusions: Overall, the study found an acceptable level of knowledge and willingness of the participants in offering BASS, suggesting that a program to provide BASS in Mures County community pharmacies may be feasible and useful.

Introduction: Hospital administration will have to constantly work around predicting demand of the critical care beds and evaluating the options of expanding the existing capacity. These expansions will be constantly requested by clinicians in private hospitals in India. It becomes imperative to infuse capital into such expansions predicting the utilisation pattern of the new beds. This study concentrates on factors considered for estimating the infrastructure enhancement in step down beds in progression of patient care.

Methodology: Retrospective measurement of past bed occupancy rates of existing critical care beds, number of patients denied admissions through emergency department due to lack of intensive care beds was counted during previous 1 year. Cost estimates of building, equipment, manpower was collected. The prices that can be charged per rack basis was estimated, for revenue calculation. Return on investment tool using annual revenues divided by annual investment was used to measure the outputs.

Results: For setting up a 34 bed HDU (High Dependency Unit), 4760 square feet of space was utilised, with USD 594,555 as investment, at a revenue of USD 527,425, which is 75% return in first year, provided occupancy is at 100%. At occupancy of 60%, which was seen within 6 months of commissioning new HDU, the breakeven can be achieved at 450 days. At 100% occupancy breakeven can be achieved in 290 days.

Conclusion: Demand estimation and Utilisation analysis is valuable tools for administration to make decisions on major capital investments.

Introduction: Mycoplasma pneumoniae is known as a common cause of respiratory tract infections, especially in children. Regarding extrapulmonary manifestations, many dysfunctions have been linked to circulating IgM antibodies, including eye diseases and disorders. In this report, we aim to highlight the importance of considering Mycoplasma pneumoniae a potential etiological agent that can cause significant eye structures inflammation.

Case presentation: We present a case of a 22-year-old male patient who arrived at the Emergency Department complaining of visual acuity decrement. Fundoscopic examination outlined a pale optic nerve, covered by pre-papillary infiltrates and peripheric inflammatory infiltrates, accompanied by signs of vasculitis. Investigations were performed and a multidisciplinary assessment was conducted. General antibiotic and antimycotic treatment and topical non-steroidal anti-inflammatory drops were administrated but his symptoms were aggravating, although it was continuously upgraded. Antibodies for Mycoplasma pneumoniae were determined with positive IgM and macrolide antibiotherapy was administrated, with favorable evolution.

Conclusions: Mycoplasma pneumoniae should not be excluded as a possible cause of severe ocular inflammations, even in asymptomatic patients. The patient’s management should include multidisciplinary assessment for an easier diagnosis in cases of uncertainty.

Objective: The aim of this study was to assess glial fibrillary acidic protein (GFAP) as a marker of short-term neurodevelopmental delay in pediatric patients with congenital defects (CHD) after cardiovascular surgical intervention.

Methods: Included patients were screened by Denver Developmental Screening Test II scale a few days before and then at 4 to 6 months after the surgical intervention. Blood samples were collected preoperatory and at 24 hours after surgery; GFAP levels were assessed by enzyme-linked immunosorbent assay using commercial kit form BioVendor.

Results: Forty children were enrolled and dichotomized into two groups based on peripheric oxygen saturation: cyanotic (<95%) and non-cyanotic (>=95%) group. 63% from our population had an abnormal neurodevelopmental outcome. Significant differences between groups were found in language domain scores preoperatory (p=0.03) and in fine motor domain postoperatory (p=0.03). In the postoperatory period, GFAP had significantly higher values (p=0.0248) in the cyanotic CHD group. Association between GFAP and NIRS were analyzed and significant differences were found in both groups with a good predicting model in the non-cyanotic CHD group (aria under curve of 0.7 for receiver operative characteristic). Higher GFAP levels from the postoperatory period correlated with neurodevelopmental impairment (mean value of: 0.66 ± 0.02ng/ml in those with good neurodevelopmental score, 0.69 ± 0.02ng/ml in those with low neurodevelopmental score, p=0.01).

Conclusions: GFAP could be a reliable neuromarker in identifying early acute brain injury documented by NIRS monitorization during perioperatory period and it also could identify short term neurodevelopmental impairment documented by lower neurodevelopmental scores.

Dystocia is a common complication of parturition in the breed of English Bulldogs, where most females are not able to have a natural parturition and many litters are delivered by caesarean section. The aim of this study was to evaluate the diameter of the pelvis of 11 females of English Bulldogs through radiographic pelvimetry and do proper measurements to observe if there are any correlations between a narrow pelvic canal and dystocia detected in the breed. The external parameters were also assessed to look for any differences between weight, height, and length in relation to the dystocia in the breed. The mean weight of the dogs with natural parturition was 21.25 ± 0.91 kg, whereas the females which had undergone caesarean section was 25.16 ± 1.44 kg (P = 0.0004). A P-value shows strong evidence for the hypothesis of this study as a possible factor of dystocia of the breed. The values of height and length in the category of dams which had undergone natural parturition were in cm 44.8 ± 2.48 (length) and 36.1 ± 0.98 (height). In the category of dogs which had undergone caesarean section, the parameters were in cm 45.4 ± 2.60 and 36.0 ± 1.58, respectively. The P-value for length were 0.72 for length and P-value for height were 0.83. Difference between the diameter of the pelvis in the two groups of English Bulldog females was P = 0.12, so there is no significant evidence. However, it could be significant for a possible future study with a higher number of animals for measuring pelvic diameter.

Giardiasis is a protozoan disease that affects the health of animals, as well as other humans all over the world. Based on its host spectrum and genetic variability, Giardia duodenalis is classified into 8 assemblages (A–H). The present study was aimed at comparing the efficiency of the three most frequently used methods (the flotation method, the SNAP test and the ELISA assay) for the detection of giardiasis in carnivores in terms of the applicability thereof for the scientific purposes and the practicality of their application in the veterinary clinical practice. In the period from March 2020 to February 2022, a total of 173 faecal samples (141 samples collected from shelter dogs; 28 samples from pet dogs; and 6 samples from working dogs) were examined by applying the flotation method. The prevalence of Giardia duodenalis identified by the flotation method was 25 %. The SNAP test conducted with the fresh faecal samples revealed the high-level efficiency of 96 %, whereas the enzyme-linked immunosorbent assay (ELISA) achieved the efficiency of 65 %. By applying the nested PCR method, five samples were positively tested for assemblages C and D (G. canis) by the amplification of the bg and tpi loci. The dogs from shelters which were positive for G. duodenalis were also presented with a coinfection caused by other intestinal parasites, such as Trichuris vulpis (28.0 %) and parasites from the Ancylostomatidae family (8.0 %).

Spinal cord injuries (SCIs) are catastrophic events in humans and animals. They often result in permanent loss of motor, sensory, and autonomic functions caudally from the site of the spinal cord (SC) lesion. The natural history of spontaneous recovery from SC trauma is disappointing and currently available therapeutic interventions fail to operate. Hence further research using bigger experimental animals or primates is necessary. The results of this study performed by the authors in 21 Göttingen-Minnesota-Liběchov female minipigs (3 sham controls, and 18 members of an experimental subgroup) showed that these animals are suitable for SCI research. All mini-pigs survived rather complex experiments carried out in general anaesthesia induced by 5 % thiopental solution administered i.v., maintained by endotracheal inhalation of 1.5 % sevoflurane with O2 as well as a subsequent 9-week monitoring period. The experimental procedures comprised of L3 laminectomy, SCI inflicted by computer-controlled metallic piston crushing the SC with 8N, 15N, or 18N force. After the SCIs there were 9 minipigs left over during the next 5.5 hours in general anaesthesia, without application of hypothermia, then the surgical wounds were sutured, and the animals were allowed to awaken under supervision. Just 30 min following SCIs was in 6 mini-pigs started with the 5-hour application of 4 °C saline via perfusion chambers placed at the epicenter of the SCI, the chambers were removed, surgical wounds sutured, and animals were allowed to awaken. Just 30 minutes following the SCIs, there was in 3 minipigs started with a 5-hour administration of ≈24 °C saline at the epicentre of the SCIs, and then the perfusion chamber was removed, surgical wounds sutured, and the animals were allowed to awaken. The 5.5-hour local hypothermia and protracted general anaesthesia required monitoring of rectal temperature, and external warming of the minipig, if the temperature dropped below 36 °C. The currently available information on the therapeutic capacity of the method, and all technical aspects of its routine employment, needs validation in further experiments and preclinical trials.
