Authors: Suryaningsih Betty Ekawati , Noegroho Trijanto Agoeng
Published: September 2024

Generalized fixed drug eruption (GFDE) is a specific variant of fixed drug eruption (FDE) characterized by multifocal lesions that recur upon exposure to a particular medication. This report describes a rare case of GFDE in a 54-year-old male, who presented with chief complaints of widespread erythema and pruritic, burning sensation. Physical examination revealed the patient to be in generally good condition dermatological status showed erosion on the hard palate, patches, erythematous macules, and partially ruptured bullae forming erosion in inguinal and genitals area, buttocks, thighs, lower legs, feet, axillae, hands, forearms, and back. The lesions were described as purplish round/oval erythematous patches, ranging from 1-4 cm in diameter, partially confluent, forming larger areas up to 6x7 cm, with bullae partially ruptured into erosion. The patient was admitted to the hospital, and treated with Ringer's lactate infusion, and an intravenous injection of 125 mg methylprednisolone. On the second day, the dose of intravenous methylprednisolone was reduced to 62.5 mg in the morning and the patient was administered a 10 mg cetirizine tablet orally in the evening, triamcinolone acetonide for oral lesions, a 15-minute NaCl 0.9% compress on the genitals twice a day, and desoximetasone 0.25% cream for all lesions. By the third day, the patient’s condition had improved, and he was then discharged. The prescribed home therapy regimen included a 16 mg methylprednisolone tablet in the morning, a 4 mg tablet in the afternoon, a 10 mg cetirizine tablet once daily, a 500 mg ciprofloxacin tablet twice daily, compress, and topical applications of triamcinolone acetonide for oral lesions and desoximetasone 0.25 % cream for all other lesions. A follow-up visit three days post-discharge indicated significant dermatological improvement. The diagnosis was established through anamnesis, physical examination, and appearance of skin disorder. Dimenhydrinate was identified as the potential causative agent.
Differences in livor mortis in Wistar rats due to organophosphate induction and normal mortality: A randomized experimental study
Authors: Nugroho Novianto Adi , Sena Muhammad Shokhiful Wafa Arya Wida , Suwandono Adji
Published: September 2024

Background: Pesticide intoxication, a significant global health issue, particularly in developing nations, is often caused by the most toxic pesticides, organophosphates. These substances activate the sympathetic and parasympathetic nervous systems, producing a characteristic livor mortis. It is a secondary sign of death that can be used to estimate the time and cause of death. Objective: This study aims to determine the difference in livor mortis due to organophosphate poisoning and ordinary death (decerebration) using Wistar rats.Methods: From March to April 2023, we conducted an experimental study with a posttest-only control group at the Laboratory of Animal Experiments, Faculty of Medicine, Sebelas Maret University. We used 32 male Wistar rats weighing 150-200 g, divided into control and test groups. The test group received organophosphate diazinon 1.16 ml through a nasogastric tube, while the control group was decerebrated. The data was processed with univariate analysis and an independent t-test.Results: There was a significant difference in the appearance and the persistence time of livor mortis between the control and test groups (p < 0.05). The color of livor mortis in the control group was purplish blue, while in the test group, it was reddish to blackish blue. Most of our samples displayed a distribution of livor mortis in the abdominal and dorsal regions, with a some displaying an abdominal distribution only.Conclusion: Our study reveals significant differences in the appearance and persistence time, as well as the color and distribution of livor mortis between decerebrated and organophosphate-induced dead rats.

Published: September 2024

Background: The ongoing prevalence of tuberculosis (TB) and stunting presents significant health challenges, frequently localized within specific regions of Indonesia. Spatial analysis is essential in controlling infectious diseases like TB, as it identifies disease clusters and patterns of local TB spread within an area. Objective: This study aimed to analyze the distribution of TB cases among stunted children through spatial analysis. Methods: We used a cross-sectional analytical descriptive study. We interviewed parents of stunted children using a questionnaire. The diagnosis of TB was made based on the pediatric TB scoring table. Coordinate data of sample sites were obtained using a Geographic Information System (GIS), supported by risk factor analysis of TB. We then created a disease distribution map using the spatial analysis by Moran's Index and Nearest Neighbor Index (NNI) methods. Results: There were 15 childhood TB cases (8.2%) among stunted children in Rambipuji District. The spatial autocorrelation test using Moran's index showed that TB cases were clustered in Rambigundam village (Moran’s index 0.2364, p-value <0.05 and Z-score >1.96). The results of the NNI analysis showed dispersed results (p-value=0.000) in all villages. Conclusion: The distribution of childhood TB cases among stunted children in Rambipuji District is primarily random, except for Rambigundam Village, which shows a clustering of cases. According to the NNI methods, childhood TB cases among stunted children are spreading throughout all villages. These results underscore the need for initiatives to curb TB transmission, especially among stunted children, which should be targeted at all villages.

Purpose – This study investigates the moderating role of political capacity (PC) in the relationship between public entrepreneurship (PE) and local government performance (LGP) in Niger State, Nigeria, using structural equation Modelling (SEM).Methodology – This study is a quantitative research based on a sample of 1,396 employees from four local government areas in Niger State, Nigeria. A non-probability sampling method was utilized, and the data were analyzed using STATA version 17 to obtain descriptive statistics, perform a normality test, assess factor loadings, and conduct correlation and SEM analyses.Findings – The analysis revealed that the mean values of public entrepreneurship, political capacity, and local government performance were low. The SEM analysis found that political capacity significantly moderates the relationship between public entrepreneurship and local government performance and establishes a direct relationship between public entrepreneurship, political capacity, and the performance of local governments.Implications – This study suggests that political capacity should be considered in the administration of local governments, as it can lead to more effective management of municipalities.Originality – No previous research has explored the relationship between political capacity, public entrepreneurship, and local government performance using SEM in the context of local government administration.
Limits of Special Relativity
Authors: Danis Francois
Published: September 2024

HIGHLIGHTS This paper is presenting an experiment based on Ehrenfest's paradox where an effect of special relativity was expected but not observed. The validity of special relativity in our macro world will be questioned and an alternative will be offered. Indeed, special relativity has been successful in describing the behaviour of particles (Rossi & Hall, 1941), but since particles obey quantum rules, there is no observation of special relativity in our everyday world. On the contrary, there are at least two paradoxes based on special relativity: the twin paradox (Langevin, 1911) and Ehrenfest's paradox (1909). ABSTRACT After presenting the history of special relativity, the non-simultaneity of special relativity is questioned in our macro world. In addition, some issues between light clocks and the application of Lorentz transformation are presented. All this indicates that special relativity appears to be correct only for particles and would be invalid in our macro world. A new hypothesis is presented based on an adaptation of special relativity; this new hypothesis solves the anomalies and could be a solution to the twin paradox. This new hypothesis has a prediction in disagreement with special relativity. To test that prediction, a new experiment has been carried out and the preliminary results support the new hypothesis. Previously, a lack of special relativistic effects has been observed in the universe (Davis et al., 2004); that second observation is also explained with the new hypothesis.

Background and Objectives: Most of the research of the BRCA1 inactivation is focused on monoallelic germline alterations and loss of heterozygosity in tumour. The aim of this study was to identify characteristic transcriptomic pattern of monoallelic somatic BRCA1 inactivation and estimate its impact to the event-free breast cancer survival prognosis. Materials and Methods: We conducted global transcriptome sequencing of breast cancer tissue samples to identify differentially expressed genes and signalling pathways associated with monoallelic somatic BRCA1 inactivation. The study group involved 36 patient samples categorized based on BRCA1 inactivation status. Subsequently, the differential gene expression and Kaplan-Meier analyses in the groups with and without monoallelic somatic BRCA1 inactivation were performed. Results: Kaplan-Meier analysis showed tendency for longer event-free survival in patients with monoallelic somatic BRCA1 inactivation, suggesting somatic BRCA1 inactivation is favourable prognostic. Differential gene expression analysis followed by the STRING tool enrichment analysis showed significant enrichment of proteins in the extracellular region and extracellular space. Conclusion: In this study we identified transcriptomic profile of differentially expressed genes TPSD1, FABP4, CARTPT and MMP9 as indicative for homologous recombination impaired tumours with tendency for better therapy results.
The Maturation of the International Health Crisis Response: the Polish Typhus Epidemic of 1916-1923 Compared to the African Ebola Virus Disease Epidemic of 2013-2016: Part I, The Polish Epidemic
Authors: Anstead Gregory M
Published: September 2024

Poland suffered an epidemic of louse-borne typhus from 1916-1923, with 400,000 cases and more than 130,000 deaths. The causative factors were depressed economic conditions and a refugee crisis that engulfed Poland after World War I. The recognition of the epidemic in 1919 stimulated the creation of the League of Red Cross Societies (LRCS). However, the LCRS had limited resources and the Poles requested help from other governments and the League of Nations (LoN). The United States sent the American-Polish Relief Expedition to conduct delousing. However, the Polish-Soviet War of 1920 disrupted typhus control and exacerbated the refugee situation. The LoN belatedly organized an underfunded Epidemic Commission. The LCRS sent a research team that did ground-breaking work on the pathology of typhus. Into 1921, the epidemic continued, driven by refugees from typhus-stricken Russia. By 1924, typhus cases were finally approaching pre-World War I levels. Multiple factors lead to the amelioration of the epidemic. The repatriation of prisoners of war and displaced civilians had concluded by 1923. Also, there had been a steady influx of sanitary, food, economic, and medical aid from various organizations into Poland since 1919. Administratively, within Poland, the anti-typhus campaign was also conducted more effectively by the Extraordinary Epidemic Commissariat.

Authors: Ishikawa Atushi , Fujimoto Shouji , Mizuno Takayuki , Tanaka Yoshimi
Published: September 2024

Based on our interest in properties of human movement, we investigated Japanese GPS data, and arrived at the following three observations: 1) there is a strong correlation between the area of polygons created by human movement trajectories and their perimeters; 2) short-distance movement trajectories less than 5 km tend to enclose a large area like a circle; 3) long-distance movement trajectories over 5 km tend to be straight.
We also clarified the following four observations on individual attributes and external factors related to long-distance movements: 1) women tend to travel more linearly than men; 2) linearity is stronger on weekends and national holidays in areas with a large theme park; 3) linearity is weaker on weekends and holidays in areas with many historical tourist attractions; 4) these variations are created by people visiting such areas.
These properties should be incorporated when modeling the movement trajectories of humans.

Published: September 2024

Inherited retinal diseases (IRDs) are clinically complex and genetically heterogeneous visual impairment disorders with varying penetrance and severity. Disease-causing variants in at least 289 nuclear and mitochondrial genes have been implicated in their pathogenesis. In the current study, we performed exome sequencing on a 51 years-old Ashkenazi Jewish patient with non-syndromic retinitis pigmentosa (RP) and identified compound heterozygous variants in the CLRN1 gene: a known pathogenic missense [p.(N48K)] and a novel deep intronic variant c.254-643G>T. A minigene splicing assay that was performed aiming to study the effect of the c.254-643G>T variant on CLRN1 pre mRNA splicing revealed the inclusion of a pseudo-exon that was also reported to be included in the transcript due to an adjacent variant, c.254-649T>G. However, unlike the reported c.254-649T>G variant, c.254-643G>T showed aberrant splicing in a leaky manner, implying that the identified variant is not totally penetrant. The non-syndromic phenotype observed in this index case may be attributed to the leaky nature of this variant, which is causing some normal transcripts to be produced. To conclude, we report on a novel deep intronic variant in CLRN1 causing non-syndromic RP.
Definition of Optimal Time Intervals in the Queues’ Analysis: The Use of Epsilon-Entropy and Epsilon-Capacity
Authors: Kagan Eugene , Novoselsky Alexander
Published: September 2024

In the paper, we suggest a method for calculating optimal time intervals in the queue analysis. The suggested method processes partitioning of the time interval and utilizes the epsilon-entropy and epsilon-capacity of the partition for finding an optimal partition. Optimality of the partition is specified based on its epsilon-information. The suggested method is illustrated by defining the intervals for histograms of differently distributed samples and demonstrated its effectiveness in comparison with the existing methods.

Authors: Ahmad Faizan , Tariq Dr Rabeet , Kaleem Safa
Published: September 2024

Migraine is a neurological disorder characterized by severe disabling headaches with a substantial global burden and elevated morbidity rates. Extensive research has established a clear association between migraine and sex/gender, with a notably higher incidence reported in females, reaching up to 18%, which is three times greater compared to males. Additionally, women commonly experience more intense pain and greater frequency of migraine symptoms, both with and without aura, highlighting the differential impact of sex/gender on migraine presentation. This review comprehensively examines the pathophysiology of migraine, with a particular focus on the effects of sex hormones in migraine pathophysiology and the central nervous system. Furthermore, we explore various treatment modalities tailored to gender differences, including pharmacological interventions and emerging therapeutic approaches. Furthermore, we explored alternative treatment strategies such as nutraceuticals and behavioural techniques, including mindfulness and cognitive behavioural therapy. This review aims to provide a comprehensive overview of the multifaceted nature of migraine and the diverse therapeutic approaches available for their management.
Hardware Testing Methodology for Wide Bandgap High Power Converters
Authors: Chen Zibo , Guo Zhicheng , Chen Chen , Huang Alex Q.
Published: September 2024

Wide bandgap (WBG) power semiconductor devices are increasingly replacing silicon IGBTs in high-power and high-voltage power electronics applications. However, there is a significant gap in the literature regarding efficient testing methodologies for high-power and high-voltage converters under constrained laboratory resources. This paper addresses this gap by presenting comprehensive, hardware-focused testing methodologies for high-power and high-voltage WBG power semiconductor based converters, preceding the control evaluation phase. The proposed methods enable thorough evaluation and evaluation of converter hardware, including device switching characteristics, driving circuit functionality, thermal management performance, insulation integrity, and sustained operation at full power. We utilize the double pulse test (DPT) to characterize switching performance in a two-level phase leg configuration, extract circuit parasitics, and validate magnetic components. The DPT is further applied to optimize gate driving circuits, validate overcurrent protection mechanisms, and measure device on-resistance. Additionally, a multicycle test is introduced to rapidly assess steady-state converter performance and estimate efficiency. Recognizing the critical role of thermal management in high-power converters, our methodologies extend to the experimental extraction of key thermal parameters—such as junction-to-ambient thermal resistance and thermal capacitance—via a heat loss injection method. A correlation method between temperature sensor measurements and junction temperature is presented to enhance the accuracy of device temperature monitoring during tests. To ensure reliability and safety, dielectric withstand tests and partial discharge measurements are conducted at both component and converter levels under conventional 60 Hz sinusoidal and high-frequency PWM waveforms. Finally, we highlight the importance of testing converters under full voltage, current, and thermal conditions through power circulating tests with minimal power consumption, applicable to both non-isolated and isolated high-power converters. Practical examples are provided to demonstrate the effectiveness and applicability of these hardware testing methodologies.

Published: September 2024

Eco-labelling plays a crucial role in encouraging sustainable consumer behaviour by giving clear information about a product's environmental impact. This study looks at how eco-labelling affects the buying decisions of young consumers in Enugu State, Nigeria. Using a cross-sectional survey approach, 430 undergraduate students from five universities participated in an online questionnaire. The research focused on understanding how aware young consumers are of eco-labels, how these labels influence their buying decisions, and whether they are willing to pay more for eco-labelled products. The data were analysed through descriptive statistics, including average scores and variations. The results showed that young consumers have a moderate to high level of awareness of different eco-labels, with the NAFDAC Green Dot being the most recognised (average score = 4.12, variation = 0.96). Eco-labelling was found to have a significant influence on their purchasing decisions, especially in building trust in the products (average score = 4.31, variation = 0.71) and their willingness to pay a higher price (average score = 4.21, variation = 0.83). Overall, the study shows that eco-labelling has a positive impact on young consumers’ buying choices and could be a valuable tool for promoting more sustainable consumption in Nigeria. The study recommends increasing awareness through educational campaigns, building consumer trust in eco-labelling, and using effective marketing strategies to boost recognition and adoption of eco-labelled products.

Authors: Santos Marisa Domingues , Brandão Pedro
Published: September 2024

Background - Compared to the da Vinci platform, there is limited experience with the Hugo RAS platform for colorectal surgery in Europe. This difference is especially notable when considering a single complex procedure, such as total colectomy. Aim - To demonstrate the feasibility and safety of using the Hugo RAS for assisted total colectomy. Clinical case- Female patient: eighteen-year-old with Familial Adenomatous Polyposis (FAP). Her IBM was 19. She underwent a total colectomy with ileorectal anastomosis using the Hugo RAS platform. The procedure took 230 minutes and had no complications. The postoperative period was uneventful. She was discharged from the hospital on the third postoperative day. Conclusion - The Hugo RAS platform is one of the emergent minimally invasive robotic platforms that can be used even in total colectomy if the proper patient selection is made. The placement choice of arms and trocars was crucial to obtain a similar operative time of the single laparoscopic approach. The certification of Hugo’s new instruments, such as energy devices and staplers, will make this platform even more competitive.

Published: September 2024

Winter rapeseed (Brassica rapa) has good chilling and freezing tolerance. INDUCER OF CBF EXPRESSION1 (ICE) plays a crucial role in cold signaling in plant; however, its role in B. rapa remains unclear. In this study, we identified 41 ICE1 homologous genes from 6 widely cultivated Brassica species. These genes exhibited high conservation, with evolutionary complexity between diploid and allotetraploid species. Cold stress induced ICE1 homolog expression, with differences between strong and weak cold-tolerant varieties. Two novel ICE1 paralogs, BrICE1 and BrICE2 were cloned from B. rapa Longyou 6. Subcellular localization assays showed that they localized to the nucleus, and low temperature did not affect their nuclear localization. Overexpression of BrICE1 and BrICE2 increased cold tolerance in transgenic Arabidopsis, and enhanced reactive oxygen species (ROS) scavenging ability. Furthermore, our data demonstrate that overexpression of BrICE1 and BrICE2 inhibited root growth in Arabidopsis, and low temperatures could induce the degradation of BrICE1 and BrICE2 via the 26S-proteasome pathway. In summary, ICE1 ho-mologous genes exhibit complex evolutionary relationships in Brassica species, and are involved in the CBF pathway, and ROS scavenging mechanism in response to cold stress; these regulating mechanisms might be also responsible for balancing the development and cold defense of B. rapa.

Design and Development of a Low-Cost Parabolic Type Solar Dryer and Its Performance Evaluation in Drying of King Fish – Case Study in Oman
Authors: Al Haddabi1 Talal , Rajakannu Amuthakkannan
Published: September 2024

Dry Fish is a rich source of proteins and nutrients and can be eaten in many forms. Oman is one of the important fish producers in the world and having high demand in neighboring countries for Oman’s fish. Fishery sector is considered as one of the important economic development sector in sultanate of Oman. In the fishery sector, use of technology is not up to the mark because of less awareness of technology application among Omani fishermen. Also, there is a demand for a greater number of cold storages in different regions to store fresh fishes which is not materialized yet. Similarly, there is a demand of perfect and cheap technology in Oman to dry fishes to improve the profit to the fishermen. Solar energy is abundantly available in Oman and there are high possibilities in Oman to use solar energy in domestic and industrial applications. Since the sunlight is available throughout the year, it is possible to convert in to thermal energy or electrical energy. Electricity can be produced from photovoltaic principle (PV) or indirectly with concentrated solar power. Similarly, we can use solar concentrators for many thermal applications. The solar dryer is a device which is used to dry fruits, vegetables, leaves, clothes etc. If any of the items are dried with the help of solar energy, then we can save lot of non-renewable source of energy and can help to improve economy of the country. The sun can, at least seasonally at Oman’s latitudes, provide a substantial part of the energy needed for various applications. In this work, we used solar dryer to make dry fish with high quality. Use of parabolic type concentrator to dry the fish is an effective solution which is an innovative idea to the fishermen. The temperature variation in dryer is directly proportional to the intensity of solar. The tracking mechanism is a combination of electronic and mechanical design which tracks the sun automatically. In this work, a parabolic concentrator with automatic tracking mechanism was designed and the performance analysis have been done. In the design, copper tubes are used for heat transfer and then the hot fluid is circulated in the box which is used to dry the fishes. As per the experiment, fish drying efficiency obtained from solar dryer is 77.9% and it took 3 days to dry king fish of 20kg. There are many advantages in parabolic type solar concentrators relate to the quality of dryness in the fishes and time taken to dry the fishes which are elaborately discussed in this paper. This solar dryer technology will improve green environment and also will save non-renewable sources of sultanate of Oman for longer period of time.
Cross-task Differences in Cortical Activations for Dynamic
Balance in Neurotypical Adults

Published: September 2024

Although significant progress has been made in understanding the cortical correlates underlying balance control, these studies focused on a single task limiting the ability to generalize the find-ings. Different balance tasks may elicit cortical activations in the same regions but show different levels of activation because of distinct underlying mechanisms. In this study, we instructed twenty young, neurotypical adults to maintain standing balance while the standing support surface was either translated or rotated and investigated the differences in cortical activations between these two widely used tasks using whole head electroencephalography (EEG). Addi-tionally, we investigated whether transcranial magnetic stimulation could modulate these cortical activations. We found higher delta and lower alpha relative power over the fronto-central region during the platform translation task when compared to the platform rotation task suggesting greater engagement of attentional and sensory integration resources for the former. Continuous theta burst stimulation (cTBS) over the supplementary motor area (SMA) significantly reduced delta activity in the fronto-central region but did not alter alpha activity during the platform translation task. Our results provide a direct comparison of neural activations between two commonly used balance tasks and are expected to lay a strong foundation for designing neuro-interventions for balance improvements with effects generalizable across multiple balance scenarios.

Published: September 2024

The information about the BCoV receptors, co/receptors that might be involved in the BCoV entry to the host cells is inconceivable. In addition to that, the roles of other host cell proteases, such as Furin and TMPRSS2, have not yet been well studied during BCoV replication. The current study’s main objectives are to identify some novel BCoV receptors and host cell proteases that might fine-tune the BCoV replication, tissue tropism, and molecular pathogenesis. We used a combination of some in silico prediction, molecular docking, and gene expression profile tools to predict some new BCoV receptors out of some known other coronavirus receptors and some host cell enzymes that are potentially involved in BCoV replication. To achieve these goals, we applied the in-silico prediction tools to check the potential interactions between eh BCoV/S glycoprotein and some known coronaviruses receptors (ACE2, APN1, NPR1, CECAM-1, AXL, and DPP4). We also established some potential models for the interaction between the BCoV/S and some common host cell proteases proved to play important roles in other coronavirus replication cycle (Furin, TMPRRS2, and Cathepsin-L). To confirm our prediction models, we assessed the gene expression profiles of these potential receptors and proteases in some bovine cell lines infected with BCoV using the next generation sequencing and the qRT-PCR assay. Our results show that the NPR1, AXL1 and the ACE2 have the strongest and firm binding affinities to the BCoV-S protein. Our prediction models and gene expression profiles show the potential bindings of the Furin and TMPRSS2 to the BCoV-S polybasic cleavage site (RRSRR|A). Notably, high expression of the host cell Furin was observed in response to both BCoV/Ent and BCoV/Resp infection, whereas TMPRSS2 expression was upregulated in the case of the BCoV/Ent infection, positioning Furin as a common receptor for different BCoV isolates. Further research is needed to study the roles of these top-ranked receptors and host cell proteases in molecular pathogenesis, and tissue tropism.

Published: September 2024

The main goal of optimization is to find factors values that bring minimum feedstock consumption or maximum final product or services of the production process. In a production process, the factors that make up the model that describes it are usually the properties of the final product. In the case of biodiesel, which is the final product of the process that is the object of study, among the various properties, the glycerol content is among the most important. The present study aims to maximize the model yield that defines glycerol content on the biodiesel composition. This optimization was executed by a hybrid metaheuristic algorithm (SAGAC),and its experimental results are compared with other optimization techniques named by RSM (Response Surface Methodology). After run the experimental assays, SAGAC algorithm has find the follow values of model factors: molar ratio = 3(mol/mol), catalyst content = 0.52 (wt%), reaction temperature = 49(oC), Time = 45 (min) generating model yield of 14.46 that, match with EN 14105 standard value of 0.33 (wt%). Comparing results between SAGAC and RSM methodologies, SAGAC has presented an improvement of 31%.

Authors: Maebara Kazuaki , Yamada Yukiya
Published: September 2024

Leisure education has the potential to improve quality of life and prepares students for social par-ticipation after graduation. This study aimed to elucidate the perspectives of special education teachers regarding leisure instruction. This study surveyed 538 teachers from 10 special needs schools for students with intellectual disabilities in Prefecture A, a rural area of Japan. An online survey was conducted from October 21 to November 17, 2023. The survey items were based on 13 aspects of leisure instruction identified from a literature review related to leisure instruction in Japan and a qualitative analysis of interviews with high school teachers in special needs schools for stu-dents with intellectual disabilities. The results showed that “The ability to pass time during brief periods of free time,” “Various activity experiences that lead to leisure,” and “Knowing one’s strengths and weaknesses in activities” were significantly more important during school. Con-versely, “understanding the psychological importance of leisure,” “connecting with organizations that support leisure activities,” and “finding places to engage in leisure activities” were significantly more important after graduation. The results of this study will be used to identify gaps in percep-tions between special education teachers and vocational rehabilitation practitioners responsible for post-social participation support.

Published: September 2024

Adaptive hyperactivity, characterized by increased activity levels and novelty-seeking traits without mood disorders, is prevalent among older adults in Sardinia's "blue zone," an area with high longevity. This study aims to evaluate the adaptive nature of hyperac-tivity concerning quality of life, social rhythms, and mood symptoms in individuals from this region, particularly among older adults over 80. Methods: This observational cross-sectional study included adults and older adults over 80 years from Sardinia's blue zone, recruited from the dermatology clinic at the University Hospital of Cagliari. Partici-pants underwent psychiatric interviews and completed the Mood Disorder Questionnaire (MDQ), Patient Health Questionnaire (PHQ-9), SF-12, and Brief Social Rhythm Scale (BSRS). Data were compared with national and regional normative data. Results: Older adults in the blue zone demonstrated higher MDQ positivity (22.58%) compared to na-tional averages (0.87%), without corresponding increases in dysregulated rhythms, de-pressive symptoms, or reduced quality of life. Younger elders (65-79 years) showed in-creased rhythm dysregulation (BSRS score: 20.64±7.02) compared to adults (17.40±6.09, p=0.040), but this trend was not observed in older elders (80+ years). No significant differ-ences were found in CH3SH and (CH3)2S levels between groups. Conclusions: Hyperactiv-ity observed in older adults from Sardinia's blue zone appears adaptive, not linked to so-cial rhythm dysregulation, depressive symptoms, or diminished quality of life, suggesting resilience factors that may contribute to longevity. These findings support the potential classification of such hyperactivity as beneficial rather than pathological, warranting fur-ther research into biomarkers and psychoeducational interventions to prevent the onset of bipolar disorders in predisposed individuals.

Integrated Fixed Film Activated Sludge (IFAS) technology greatly enhances nitrogen removal effectiveness and treatment capacity in municipal wastewater treatment plants, addressing the issue of limited land availability. Hence, this method is appropriate for treating household wastewater from office buildings. The research was conducted at the wastewater treatment plant in an office building in Ho Chi Minh City, Vietnam. Experiments were conducted to ascertain the most favorable working conditions, including Hydraulic Retention Time (HRT), alkalinity dosage, and Dissolved Oxygen (DO). According to the study, the IFAS system had the highest nitrogen removal effectiveness when operated at a hydraulic retention time (HRT) of 7 hours, an alkalinity dose of 7.14 mgCaCO3/mgN-NH4+, and a dissolved oxygen (DO) value of 6 mg/L. The nitrification efficiency ranges from 89.2% to 98.8%. The nitrate concentration post-treatment is within the range of 27 – 45 mg/L, which is lower than the allowable discharge limit of 60 mg/L as per Vietnam's wastewater discharge requirements. The research findings have enhanced the efficiency of the office building management process, thereby promoting the sustainable growth of society.

Background: Cardiovascular risk in prediabetic patients is substantial yet it is often underestimated in everyday clinical practice. Objectives: This study examines the future cardiovascular risk in prediabetic patients presenting with ST-segment elevation myocardial infarction (STEMI). Methods: We conducted a retrospective analysis of 725 STEMI patients at a tertiary center in Austria between 2018 and 2020, categorized into groups of non-diabetic, prediabetic, and diabetic patients. Baseline characteristics, cardiovascular risk factors, and long-term survival outcomes were compared using Kaplan-Meier survival analysis along with other statistical tests. Results: Of the 725 patients, 407 (56.1%) were non-diabetic, 184 (25.4%) prediabetic, and 134 (18.5%) diabetic. Prediabetic patients exhibited significant additional cardiovascular risk factors, such as arterial hypertension (67.4%) and dyslipidemia (78.3%), with prevalence rates between those of non-diabetic and diabetic patients. Kaplan-Meier analysis revealed that at three-year follow-up, prediabetic patients faced a survival disadvantage with a significant decrease in survival rates compared to non-diabetic patients (log-rank p = 0.016); their survival outcomes approached those of diabetic patients (p = 0.125). Conclusions: Our findings underscore the critical need for early identification and aggressive management of prediabetes in cardiovascular care of patients after acute STEMI. In current clinical practice, prediabetic patients are often underdiagnosed and undertreated, putting them at disproportionate risk. Integrating rigorous cardiovascular risk management strategies for prediabetic individuals, including lifestyle interventions and potentially pharmacological treatments, could prevent the progression to diabetes and mitigate associated cardiovascular risks. This paradigm shift in treating prediabetes as seriously as diabetes may significantly improve long-term survival outcomes for this vulnerable population.
Hybrid Biomechanical Design of Dental Implants: Integrating Solid and Gyroid TPMS Lattice Architectures for Optimized Stress Distribution

Published: September 2024

Dental implantology has evolved greatly as a result of the application of biomechanical engineering concepts, notably the utilization of additive manufacturing technologies that recreate the intricate architecture of real bone. This technique intends to improve functional compatibility with bone tissue while also addressing continuing problems of stress distribution inside dental implants. The research examines two types of dental implants: fully gyroid latticed and hybrid gyroid latticed with a solid neck, comprising three different cell sizes—FI-111, FI-222, FI-333, and their hybrid equivalents HI-111, HI-222, and HI-333. Traditional solid implants often cause stress shielding, which reduces long-term osseointegration and implant durability. Developed using nTopology for lattice configuration and meshing, this design undergoes a comprehensive stress analysis using finite element analysis (FEA). The study seeks to determine the most efficient implant design by maximizing stress distribution and mechanical stiffness. Analyses suggest that hybrid latticed implants, notably the HI-222 type, possess superior mechanical characteristics. These implants successfully balance stiffness and flexibility, reducing stress concentrations and improving stress distribution throughout the implant structure. This balance is critical for decreasing micromotions at the bone-implant interface, boosting osseointegration, and, ultimately, increasing implant longevity and success rates in clinical settings. The paper describes a substantial redesign of dental implants by combining biomechanical engineering and modern additive manufacturing. The novel proposed hybrid structure not only addresses typical challenges such as stress shielding, but it also establishes new standards in implantology, potentially leading to better clinical results and patient quality of life. This complete approach emphasizes the ability of personalized implant designs to fulfill individual clinical demands, indicating a significant improvement in dental treatment technology.

Porcine circovirus-associated diseases, caused by porcine circovirus type 2 (PCV2), are widespread and result in significant economic losses to the global swine industry. It is generally believed that PCV2 can be divided into nine genotypes (PCV2a to PCV2i), with the dominant being the PCV2d genotype. In this study, 2675 samples from pig farms in 13 cities in Jiangsu Province, China, were collected between 2014 and 2021 and subjected to polymerase chain reaction analysis to investigate the prevalence and genetic diversity of PCV2. The results showed that 41.42% (1108/2675) of samples tested positive for PCV2. The researchers further analyzed the genetic characteristics of 251 PCV2 strains and found that they belonged to the following four genotypes: PCV2a, PCV2b, PCV2d, and PCV2i. The dominant genotype was PCV2d, with a prevalence of 49.80% (125/251). The detection rate of PCV2b was significantly higher than those of PCV2a and PCV2i, at 35.46% (89/251), 7.57% (19/251), and 7.17% (18/251), respectively. We have further revealed the fingerprint of PCV2i genomic nucleotides for the first time. In conclusion, this study illustrates the high prevalence and evolutionary features of PCV2 in Jiangsu Province over the past few years.

The development of an electric discharge during photon scattering in a dielectric material is considered. A preliminary mathematical model of the discharge process is presented. The model is based on a quantum kinetic equation for quasi-free charge carriers produced by bulk radiation effects and impact ionization. Equations are obtained for the concentration, drift current density, and gas temperature of quasi-free electrons. A test example is considered, confirming that the model does not contradict the known conditions for the formation of an electric discharge.
