Authors: Pham Chau , Pung Chris , Jiao Lihong (Heidi) 
Published: October 2024

Amid escalating global energy demands and environmental concerns, the transition to renewable sources like solar power is imperative. Despite the advancements in photovoltaic (PV) technology promising increased efficiency, soiling on PV panels—composed of dust, bird droppings, and contaminants—poses a significant challenge, obstructing sunlight and reducing energy conversion efficiency. Building upon existing research on titanium dioxide (TiO2) nanoparticle coatings, our study investigates their super-hydrophilic and anti-soiling characteristics to enhance self-cleaning capabilities in solar applications. Furthermore, our research investigates the application of (3-aminopropyl)trimethoxy silane as an interlayer to reinforce the adherence of the TiO2 coating to PV panel glass, thereby enhancing its durability. Preliminary results highlight the coating’s exceptional super-hydrophilic properties, with water contact angle measurements less than 10°, indicative of TiO2’s strong water affinity. Spectrophotometer measurements show that the developed coating maintains high optical transmittances for the wavelength range from 350 to 800 nm, which is the most crucial factor for energy conversion in solar panels. Our contributions aim to advance solar energy technologies and support the shift towards more sustainable energy solutions, highlighting the role of innovative materials science in addressing solar power’s operational challenges.

Government policies that carry out large-scale social restrictions during the Covid-19 period have had an impact on reducing air traffic both for landings and takeoffs, which will have an impact on the life of runway services. Service life is the strength of road pavement in standing the repetition of permit loads before experiencing failure, by knowing that the service life can be directly used to determine the right time for runway maintenance. The purpose of this research is to determine the impact of the Covid-19 pandemic on the life of runway services. The method used in this research is the FAA method with the help of FAARFIELD software, this software calculates the service life based on the CDF value of each aircraft. The data used is secondary data in the form of aircraft type data, CBR ground, and existing pavement data. From the results of the research, it is known that the COVID-19 pandemic has a positive impact on the life of runway service by increasing the life of runway service by 4 years, where in the condition of covid-19 conditions it has a CDF value of 0.20 with a service life of 19 years and in normal conditions the CDF value is 0.22 with a service life of 15 years. The results of this research contribute to decision-making in carrying out maintenance and repairs on the runway of Soekarno Hatta International Airport so that the runway can operate sustainably in accordance with performance requirements throughout the life of the plan, to maintain flight safety and comfort.

Published: October 2024

Introduction Surgical site infections (SSI) continue to be a risk associated with surgery. The Centers for Disease Control (CDC) uses surgical wound class (SWC) to predict SSI postoperatively. Prior studies have shown that the current wound class definitions are unreliable for surgical subspecialties. Therefore, an alternative surgical wound classification (ASWC) was created to more accurately reflect risk of SSI following orthopedic procedures. The purpose of this study was to compare the two systems. Methods Seventy patients who developed 90-day SSI following total joint arthroplasty (TJA) were matched 1:1 to patients without postoperative SSI. The SWC was recorded from operative reports. Wounds were then retrospectively reclassified according to the ASWC based on preoperative history from the medical record. The degree of agreement and degree of association with occurrence of SSI was compared between the two systems. Results The proportion of agreement between the systems was poor (41.4%). The current SWC was associated with risk of SSI in both unadjusted (p=0.045) and multivariable analysis (p=0.050). Comparatively, the ASWC demonstrated a stronger association with SSI in both unadjusted (p=0.001) and multivariable analysis (p=0.001). Conclusion The results of this study suggest that the ASWC is more predictive for SSI following TJA than the current SWC definitions for total joint arthroplasty.

Published: October 2024

Diferentes parámetros de laboratorio se ven alterados durante el curso de la infección el virus del Dengue. Su determinación y seguimiento es indispensable para evaluar la evolución del paciente infectado. Si bien la elevación de las transferasas (ASAT y ALAT) es un hallazgo frecuente, en la mayoría de los casos leve y autolimitada, su cuantificación es un elemento importante para valorar la función hepática, cuya afectación puede llevar al paciente a cuadros clínicos graves y potencialmente fatales. El objetivo del presente estudio fue realizar un análisis sobre el comportamiento de diferentes parámetros de laboratorio, especialmente de las enzimas ASAT y ALAT, durante la infección por el virus del dengue. Se analizaron las historias clínicas de 108 pacientes con diagnóstico de dengue confirmado que asistieron al Hospital G. Rawson de la ciudad de Córdoba en el período comprendido entre enero y abril de 2016. Equipamiento empleado: autoanalizador químico TARGA-BT3000 Plus (Wiener) y contador hematológico CELL-DYN 1800 (Abbott). El análisis estadístico de los datos se realizó con el Software Infostat versión 2011. Se observó un descenso significativo del recuento de glóbulos blancos y plaquetas a partir del tercer día luego del comienzo de los síntomas. El aumento de las transferasas se evidenció en un 84,3% y 75,9% para ASAT y ALAT respectivamente. No se encontró un incremento diferencial entre estas enzimas, así como tampoco entre el incremento en los pacientes ambulatorios respecto de los internados. Demostramos un incremento paulatino de los niveles de transferasas en los primeros días de la infección.
Assessing the Reliability, Dimensions, and Variance of Young's Internet Addiction Test by Applying it to Adolescents at the National Psychiatric Hospital in Costa Rica
Authors: Martín Herrero José A. , Fernández Mora Karla , Molina Fernández Antonio 
Published: October 2024

Background: The Internet Addiction Test (IAT) was the first instrument created specifically to assess Internet addiction (IA). Although it was not validated during its creation, its validity has since been confirmed thanks to subsequent studies. The IAT is the first global psychometric measure tested worldwide that has been used in several studies as a research tool. Regarding the dimensions of the IAT, they were not reported by the creator of the test, during the performed factor analysis. Nonetheless, different studies have defined the test as being one-dimensional and others as having three, four, five, and six dimensions.
Methods: In the present study, seven dimensions were identified; however, there is still a lack of consensus about the number of dimensions that accurately define this test.
Results: Hence, Young's Internet Addiction Test presents a shortcoming that may be explained by the influence of several factors such as how it was applied, the place where it was applied, and the population to which it was applied. All of these are factors that could be linked to the sociocultural aspects of the adaptations that have been made to the test.
Conclusions: Moreover, the first dimension of the IAT found, the loss of self-control, is extremely important because it explains 34% of the variance of the data. However, 74% of the variance is explained by applying the 7 dimensions identified in this research. Also, the reliability analysis showed that the IAT is 89% reliable, which indicates that the elements comprising the test used in this research are suitable for measuring the construct of Internet addiction.

Published: October 2024

Eucalyptus urophylla S.T. Blake, an important economic tree species, is widely cultivated as a raw material source for pulpwood, veneer plywood, and sawlog timber in southern China. As a tree in multiple environments, tree-breeding programs can assess genotype by environment (G × E) interactions and identify the suitable genotype for a specific environment. G × E interactions related to growth traits and soil factors have not been adequately studied for clones of Eucalyptus urophylla and its hybrids. To examine this important question, trials containing 20 clones of E. urophylla and its hybrids were established at three sites in southern China: Shankou (SK), Tiantang (TT), and Xiniujiao (XNJ). These sites each have different soil conditions but similar geographical and climatic conditions. With the data across nearly eight years, average phenotypic trends and broad sense repeatability (H2) were modeled, G×E interactions between clones and diverse soil environments were estimated, genetic gains of clones were calculated, and the adaptabilities of E. urophylla clones in different soil environments were compared. Average survival trends for clones tended to show a moderate decrease while growth traits tended to show sharp increases with age. At the same age, sites were ordered for average survival and growth traits as TT>SK>XNJ while H2 values for growth traits by site followed the basic order TT>SK>XNJ. The H2 values for growth traits at SK tended to increase at first, platform, and then smooth with age. The H2 values for growth traits at TT were high and stable across ages, and those at XNJ tended to undulate largely at a relatively low level across ages. Genetic correlations for growth traits between any pair of sites tended to increase at first and then decrease. A genetic correlation was strong between SK and TT, intermediate between SK and XNJ, and weak between TT and XNJ. It was concluded that: (1) clones tended to be adapted better to an environment with acidic and loamy soil with a clay content of about 45.6%, the soil depth from the surface to parent material about 1.5 m, and the previous vegetation of Eucalypts. (2) The G×E interactions between clones and sites are weaker if the environmental conditions between the sites are similar, and which are stronger if the environmental conditions between the sites are different. (3) The optimum selection age for clones ranged from 1.5 to 3.5 years old, while the optimum selection growth trait is individual tree volume.
Expression of neutrophil extracellular trap-related proteins and its correlation with IL-17 and TNF-α in patients with oral lichen planus
Authors: Cheng Juehua , Zhou Chenyu , Liu Jia , Geng Yanlin , Liu Lin , Fan Yuan 
Published: October 2024

Background
Neutrophil extracellular traps (NETs) are produced by polymorphonuclear neutrophils (PMNs) stimulated by interleukin-17 (IL-17) and tumor necrosis factor α (TNF-α). However, the level and role of NETs in oral lichen planus (OLP) remain poorly understood.

Objective
This study aimed to investigate the expression of NETs in OLP and explore the correlation between NETs and the levels of IL-17 and TNF-α.

Methods
The expression and distribution of NET-related proteins in tissue samples from each group were assessed using hematoxylin-eosin (HE) staining and immunofluorescence (IF). Additionally, the expression of NET-related proteins in peripheral blood samples from each group was evaluated using cell IF technique and fluorescence spectrophotometry. The relative formation level of NETs in each group was determined by fluorescence spectrophotometry via plasma co-culture. Furthermore, the levels of inflammatory cytokines IL-17 and TNF-α in plasma and culture supernatant were measured using enzyme-linked immunosorbent assay (ELISA).

Results
NET-related proteins were located in the subepithelial and lamina propria layers of OLP lesions. OLP had significantly higher expression of NET-related proteins in lesion tissues and peripheral blood compared to the healthy control (HC) group (p < 0.05). The rate of NETs formation in the erosive-stage OLP (EOLP) group was significantly higher than that in the HC group (p < 0.05), in contrast, no significant increase was observed in the non-erosive OLP (NEOLP) group (p > 0.05). Furthermore, the levels of IL-17 and TNF-α in the EOLP group were significantly elevated compared to those in the NEOLP group and HC group (p < 0.05), while the levels in the NEOLP group did not significantly differ from those in the HC group (p > 0.05). The rate of NETs formation showed a positive correlation with the levels of IL-17 and TNF-α in plasma.

Conclusion
The expression of NET-related proteins was upregulated in OLP lesion tissues and peripheral blood. Elevated levels of IL-17 and TNF-α in peripheral blood plasma positively correlated with the rate of NETs formation, suggesting that IL-17 and TNF-α mediate the formation of NETs in OLP patients, and may thereby contribute to the development of OLP.

Published: September 2017

AbstractSpinel LiMn2O4 is one of the most important cathode materials but it still suffers from rapid capacity degradation during electrochemical cycling. Beside surface coating to improve the electrochemical performances, controlling the bulk morphology of LiMn2O4 (LMO) is another effective strategy. In this work, porous LiMn2O4 microspheres composed of numerous primary nanoparticles are synthesized by micro‐emulsion and co‐precipitation methods. The porous structure and the primary nanoparticles size of LiMn2O4 are effected by the concentration of micro‐emulsion and the precursor of Mn2+. The well‐established porous LiMn2O4 microspheres with abundant ionic channels and good contact with electrolyte endow the spinel a remarkable electrochemical performance. After 300 cycles, 0.50 M‐LMO sample presents excellent reversible capacity of 112.8 mAh g−1 at 0.5 C rate. After 1000 cycles, 0.50 M‐LMO sample presents the highest capacity of 97.9 mAh g−1 and remains 54.2 mAh g−1 at the current rate of 10 C. The porous spherical structure of cathode materials is essential to improve the rate performance due to the good contact between the active material and electrolyte.

SUMMARYHuman tuberculosis (TB) caused byMycobacterium bovissurveillance is affected by a lack of data. The aims of the present study were: (i) to estimate the proportion of human TB caused byM. bovisover a period of 5 years in Bologna, Northern Italy, which, like most Western European countries, has been declared bovine TB-free; (ii) to compare the genetic profiles ofM. bovisstrains identified in humans with those circulating in cattle in the last 15 years in Italy. Among 511 TB patients, the proportion of human TB caused byM. boviswas 1·76%, significantly associated to extra-pulmonary localization (P= 0·004) and to being elderly (P< 0·001) and Italy-born (P= 0·036). The molecular epidemiology analysis by spoligotyping and Multilocus Variable Tandem Repeat Analysis confirmed that mostM. bovisstrains from Italy-born patients matched those circulating in cattle herds in Italy between 2001 and 2016. Two cases ofMycobacterium bovisBCG infection were also characterized. In conclusion, the rate of human TB caused byM. boviswas not negligible, highlighting the relevance of molecular typing in evaluating the effectiveness of programmes designed to eradicate TB in cattle in Italy.

AbstractThe methadone maintenance treatment (MMT) has been initiated in Wuhan, China since early 2006. To understand the social-demographic, behavioral, and infectious diseases characteristics of drug users enrolled in their first-ever-MMT between 2006 and 2015, a retrospective observational study was implemented to also provide evidence for health policy-decisions to reduce harm and control disease. Pearson chi-square tests and t-tests were used to assess significant differences between two 5-year periods, 2006–2010 and 2011–2015. We observed increases in the mean age (38.65 vs. 42.43 years, P < 0.001), mean age of initial opioid drug use (28.18 vs. 31.07 years, P < 0.001), employment (11.9% vs. 30.7%, P < 0.001), married/co-habiting (42.4% vs. 47.8%, P < 0.001), and declines in higher education level (93.6% vs. 84.8%, P < 0.001), injection (82.3% vs. 75.1%, P < 0.001), syringe sharing (27.7% vs. 9.9%, P < 0.001), HCV infection rates (72.9% vs. 70.5%, P = 0.017). The number of drug users enrolling each year reduced following a continuous rapid growth in the first 3 years. The findings imply for adjusting in treatment services and allocation of resources to respond to emerging trends. In addition, the data will also be helpful for identifying needs and getting a baseline insight of the social-demographic and behavioral characteristics of the opioid abusers in the area.

Published: September 2017

ZusammenfassungDiabetes mellitus repräsentiert weltweit ein zunehmendes Gesundheitsproblem, das viele Komplikationen einschließt. Die diabetische Fußulzeration (DFU) stellt eine schwer zu therapierende und kostenintensive Komplikation dar. In Folge können sich Infektionen schnell etablieren und sich zu chronischen Infektionen entwickeln. Dies wird durch die verminderte Immunantwort der Patienten aufgrund des Diabetes begünstigt. Pathogene Keime wie S. aureus, aber auch wenig virulente Keime wie Corynebacterium ssp. werden als ätiologische Auslöser nachgewiesen. Die Fähigkeiten dieser Erreger, den Knochen zu infizieren und darin zu persistieren, sind vielfältig und liegen im Fokus vieler Forschergruppen. Entscheidend für den Heilungsprozess ist das erfolgreiche Zusammenspiel von antibiotischen und chirurgischen Maßnahmen, die unter anderem sowohl eine Wundsanierung als auch eine Revaskularisierung einschließen. Das Ziel ist es, die Anzahl der DFU und die dadurch bedingten Infektionen und Amputationen zu reduzieren.
