Published: August 2024

Background
Climate change, land development, and increased outdoor human activity have increased the prevalence and distribution of tick-borne pathogens, causing public health issues. Asia is considered a pivotal region of emerging infectious diseases caused by zoonotic disease, thus requiring active research in Asian countries. Therefore, this study aimed to conduct effective surveillance systems and establish preventive strategies against introducing novel tick-borne diseases.
Methods
Blood-fed ticks (n = 261) were collected from different animals across nine Asian countries between 2022 and 2023. Five genera of adults and nymph ticks were used, including Amblyomma, Haemphysalis, Hyalomma, Rhipicephalus, and Ixodes. Animals that collected the ticks were wild, domestic animals, birds and reptiles. Next-generation sequencing was performed to detect unknown pathogens circulating in the animals.
Results
From blood-fed ticks, clean reads of 18,382,262 − 30,460,619 of DNA viruses, 22,744,384 − 32,400,471 of RNA viruses, 134,506–286,282 16S rRNA of bacteria, and 147,154–352,826 18S rRNA of protozoa were obtained in nine Asian countries. After analysis of species, 28 RNA and 13 DNA viruses, 16 bacteria and 4 protozoa were detected. Several tick-borne pathogens including families, that cause zoonotic diseases, such as Phenuiviridae, Nairoviridae, Rickettsiaceae, and Borreliaceae were identified.
Conclusion
This study is distinctive as cooperative studies with nine Asian countries to prevent the spreading of tick-borne diseases across Asian regions. The results suggest that pathogens, which were detected from animal blood-fed ticks, can circulate in the animals and can be transmitted to humans. In addition, this study can provide a basis for effective surveillance systems to prevent novel pathogens.

Insights into the Spatial Ecology of Sambar Deer (Cervus unicolor) in Bhutan’s Protected Area at Phrumsengla National Park: Habitat Preferences and Conservation Challenges
Authors: Dorji Rinchen , Dorji Yonten
Published: August 2024

Sambar (Cervus unicolor) is considered an important prey species of Tiger and other carnivores throughout South and Southeast Asia. However, the ecological information on Sambar deer in Bhutan is scarce. Therefore, this study represents a pioneering effort to evaluate habitat preferences and assess the impacts of both natural and anthropogenic disturbances on Sambar occurrence within Phrumsengla National Park, a designated National Protected Area. The study area was stratified into three forest types and the standard line transect method was employed for data collection. A total of 90 plots were established, comprising 45 already used by Sambar and 45 control plots representing other available habitats. The study analysis revealed that Sambar highly preferred an elevation range of 2356 - 2680 masl with northeast-facing slopes of 0 - 15o, preferred a canopy cover of 51 - 75%, a ground cover of 61 - 76%, distance to water sources of 101 - 200 m. The study also identified preferred vegetation types, with Sambar showing a marked association with tree species such as Taxus baccata and Betula utilis, shrub species like Sarcococca hookeriana, and herbaceous plants including Stellaria vestita. Furthermore, Sambar favored cool broadleaved forests over mixed conifer and fir forests. Livestock grazing was the prominent anthropogenic disturbance, followed by timber extraction, which had a strong negative correlation with significant difference (p < .05). The findings underscore the necessity for stringent regulations regarding livestock grazing and resource extraction within protected areas. To build on this foundational study, long-term monitoring and further research are essential for developing targeted conservation strategies and interventions, ensuring the sustainability of this vital species and its habitat.

Forest structure complexity is an essential variable in forest management and conservation, as it has a direct impact on ecosystem processes and functions. Previous studies have primarily focused on tree cover as a proxy, which often falls short in providing comprehensive information on the structural complexity of forests. Sub-meter resolution remote sensing data and tree crown segmentation techniques hold promise in offering detailed information that can support the characterization of forest structure and complexity. In this study, we generated a dataset with over 5 billion tree crowns, and developed an Overstory Complexity Index (OCI) to characterize forest structure complexity from a horizontal perspective, by analyzing spatial relationships among neighboring trees from remote sensing optical images. We first extracted the location and crown size of overstory trees from optical satellite and aerial imagery at sub-meter resolution. We subsequently calculated the distance between tree crown centers, their angles, the crown size and crown spacing and linked this information with individual trees. We then used Principal Component Analysis (PCA) to condense the structural information into the OCI and tested it in China’s Guangxi province, Rwanda, and Denmark. In addition, we conducted a comparative analysis of OCI between protected and unprotected areas and among different forest types across these regions. Finally, we explored the relationships of terrain slope, distance to settlement and aboveground biomass with the OCI. Our result showed that the distribution of OCI values varies across the different bioclimatic regions, closely related to their respective forest characteristics. Higher OCI values were observed in protected areas as compared to unprotected areas, and OCI showed a positive correlation with terrain slope, distance to settlement and aboveground biomass. The proposed OCI is derived directly from standard tree-level attributes and supports a deeper understanding on forest structure and complexity in diverse ecosystems as compared to existing proxies.
VYGOTSKY - SOBRE O PLURILINGUISMO NA IDADE INFANTIL (1928)
Authors: Souza Fábio Marques de , Di Camargo Junior Ivo , De Sousa Nóbrega Aguiar Pereira Laís
Published: August 2024

Este artigo apresenta uma tradução, do espanhol para o português, do texto escrito em 1928 por Lev Semionovitch Vigotski (1896-1934), psicólogo russo e proponente da Psicologia histórico-cultural. Publicado pela primeira vez em 1935 no livro intitulado “Umstvennoie razvitie detei v protsesse obucenia [O desenvolvimento intelectual das crianças no processo educativo], em Moscou, pela editora Ucpedgiz”. Ao tecer reflexões a respeito do plurilinguismo na idade infantil, o pensador discute sua influência no desenvolvimento psíquico e linguístico das crianças. Destaca-se a importância da linguagem interna e externa no processo de resolução de problemas, evidenciando seu papel crucial no desenvolvimento cognitivo. O autor ressalta que o plurilinguismo não apenas afeta a pureza da língua materna, mas também influencia o desenvolvimento emocional e de caráter da criança. A interação entre diferentes sistemas linguísticos pode resultar em inibições associativas e conflitos que impactam a fluência e a expressão nas línguas dominadas pela criança. Epstein argumenta que a utilização passiva de várias línguas é menos prejudicial do que a mistura ativa, defendendo a monoglotia de expressão como ideal. Conclui-se que o plurilinguismo na infância é um tema complexo que requer investigações aprofundadas, levando em consideração a idade das crianças, a coexistência de idiomas e a influência pedagógica.
Correlation between the Atherogenic Index of Plasma and Progression of Non-target Lesion Vascular Disease Following Percutaneous Coronary Intervention using Drug-eluting Stents
Authors: Hou Tian-Hua , Wang Fei , Hao Cui-Jun , Zhang Chong , Ning Meng , Chen Yi , Wang Kun , Liu Ying-Wu
Published: August 2024

Objective:

To examine the correlation between Atherogenic Index of Plasma (AIP) levels and the
progression of non-target lesion vascular disease following the deployment of drug-eluting stents (DES).

Methods:

We retrospectively enrolled patients who had undergone successful treatment for CAD with DES
and subsequently underwent a coronary angiography follow-up at the Cardiology Department of Tianjin Third
Central Hospital from January 2017 to July 2022. The annual change in Gensini Score (GS) was calculated according
to two angiographic evaluations in order to assess the progression of non-target lesion vascular disease;
a change greater than 1 indicated progression, while a change of 1 or less indicated stability. AIP was calculated
according to serum lipid parameters. Multivariate Logistic regression model was used to evaluate the
relationship between AIP level and progression of non-target coronary artery lesions. The ROC curve analysis
was performed to evaluate the diagnostic value of AIP for coronary artery non-target lesion vascular disease
progression.

Results:

Out of the 344 patients who were monitored over a median duration of 1.2 years, 113 exhibited progression
of non-target lesion vascular disease. Initially, baseline AIP levels were notably higher in the progression
group compared to the non-progression group (0.30 [0.14, 0.43] vs. 0.11 [-0.06, 0.31]), and this difference
remained significant during the follow-up period (0.19 [0.06, 0.34] vs. 0.11 [-0.06, 0.22]). Multivariate logistic
regression revealed that AIP is an independent predictor for the progression of non-target lesion vascular disease
following DES treatment. Individuals in the highest tertile of AIP faced a considerably elevated risk compared
to those in the lowest tertile (OR = 4.88, 95% CI: 2.12-11.21, P < 0.001). Moreover, utilizing receiver
operating characteristic curve analysis, a 0.15 AIP level cut-off was determined for diagnosing disease progression,
with a sensitivity of 73.5% and specificity of 56.7%, and an area under the curve of 0.672 (95% CI:
0.613-0.731, P < 0.01).

Conclusion:

AIP significantly correlates with the progression of non-target lesion vascular disease among patients
with coronary artery disease who have undergone DES treatment, establishing itself as an independent
risk factor in addition to conventional predictors.

Authors: Zarkesh Mohammadreza , Kermani Farzaneh , Ghalibaf Mohammad Bolbolian , Orooji Azam , Moradi Raheleh
Published: August 2024

Background:

Pregnancy among women infected with HIV is classified as a high-risk
pregnancy. While previous research has indicated an elevated likelihood of preterm birth, low
birth weight, and early gestational age in infants born to mothers with HIV, the correlation between
maternal HIV infection and different neonatal results remains unclear.

Objective:

This study aims to investigate the impact of maternal HIV infection on after-birth neonatal
outcomes using machine learning (ML) and statistical methods.

Methods:

A case-control study is conducted through a three-stage process: Initially, the outcomes
among newborns from HIV-positive mothers are identified through a combination of literature review
and expert survey. Subsequently, data are paired at a 1:2 ratio based on gestational age with
infants from HIV-positive mothers (n=48) compared to HIV-negative mothers (n=96) as the control
group. Finally, various feature selection techniques are applied to identify outcomes that exhibit
significant differences between the two groups.

Results:

The statistical analysis showed that the rate of addiction among HIV-positive mothers is
higher than that of the HIV-negative group. The need for mechanical ventilation and duration of
ventilator-assisted breathing in infants born to HIV-positive mothers are significantly higher than
in infants born to HIV-negative mothers. Moreover, based on feature selection methods, increasing
the need for mechanical ventilation and reducing surfactant administration were two important
outcomes.

Conclusions:

To investigate the impact of maternal HIV infection on neonatal outcomes, various
statistical and machine learning-based feature selection techniques were implemented, and the results
showed that the presented methods can be utilized to examine the potential impacts of different
diseases contracted by the mother on the infant.

Authors: Wiyono Herdina , Meidyawati Ratna , Putranto Aditya Wisnu
Published: August 2024

Background

The smear layer causes a weak bond to dentin; therefore, removal of the smear layer with ethylenediamine tetraacetic acid (EDTA) solution was recommended. EDTA can cause erosion and changes in dentin’s microhardness. Hence, natural products that are biocompatible and have fewer side effects are being developed, one of which is Tamarindus indica. Tamarindus indica solution contains organic acids (citric acid, acetic acid, and maleic acid), therefore, it can dissolve minerals (demineralization), remove the smear layer, and act as a chelating agent.

Objective

To compare the penetration of the universal adhesive system after smear layer removal on dentin using Tamarindus indica 2,5%, 5%, 10%, and 17% EDTA solution.

Methods

Premolars (n=24) had their enamel removed, exposing the dentin. Four groups of smear layer removal agents, Tamarindus indica 2,5%, 5%, 10%, and 17% EDTA were applied to dentin. A universal adhesive system was then applied, restored with composite resin, and incubated at 37° for 24 hours. Penetration of the universal adhesive system was observed using a Scanning Electron Microscope.

Results

There was a significant difference in the penetration of universal adhesive after smear layer removal between Tamarindus indica 10% group and Tamarindus indica 2.5%, 5%, and EDTA 17% group (p <0.05). The longest resin tag penetration was found in Tamarindus indica 10% compared to Tamarindus indica 2,5%, 5%, and EDTA 17%.

Conclusion

10% Tamarindus indica solution was effective in the removal of the smear layer and resulted in longer penetration of resin tags compared to 2.5% Tamarindus indica, 5% Tamarindus indica, and 17% EDTA.

Authors: Alturki Ghassan , Jamel Ahmad , Alshuaybi Abdullah , Baeshen Hosam , Farag Arwa M.
Published: August 2024

Objectives

The main objective of this study was to compare the perception of pain intensity between patients treated with fixed orthodontic appliances and those treated with clear removable aligners. The secondary objective was to investigate the pattern and quantities of analgesics use immediately after orthodontic adjustment visits and correlate this with the intensity and quality of the perceived pain.

Methods

Two hundred participants, 100 treated with fixed orthodontic appliances (G1) and 100 with clear removable aligners (G2), filled the Short-form McGill Pain Questionnaire (SF-MPQ), the Numeric Pain Rating scale (NPRS), and the Present Pain Index (PPI) at baseline (before orthodontic adjustment or changing to a new aligner) and 24-hours post-adjustment visit.

Results

The mean change in the NPRS values from baseline to 24-hour post-adjustment showed significantly higher pain intensity in G1 (3.15±2.47) compared to G2 (1.58±1.74) (p<0.0001). There was also a statistically significant difference in the frequency of reporting of SF-MPQ pain descriptors between G1 and G2, with more pain associated with G1. The PPI 24-hours post-adjustment showed that 94% of G1 reported some form of pain compared to only 79% in G2. At the 24-hour post-adjustment visit, 34 participants in G1 and only 8 participants in G2 reported the use of analgesic medications (p<0.0001).

Conclusion

Overall, patients treated with fixed orthodontic appliances reported higher pain perception compared to patients treated with clear removable aligners during the first 24 hours following the adjustment visit.

Authors: Ban Zhangjie , Sun Zizhan , Cai Chenxi , Cai Zhengyu , Pei Lizhai
Published: August 2024

Background:

The discharging of crystal violet dye can contaminate water and soil, which
causes serious environmental pollution and health problems for human beings. Sb2O3/Ca5Al6O14
nanoscale composites possess good catalytic performance for crystal violet removal. This study
aimed to research the effects of the Sb2O3 content, content of the nanoscale composites, and metallic
cations on the photocatalytic activity of the Sb2O3/Ca5Al6O14 nanoscale composites.

Objective:

The objective was to synthesize Sb2O3/Ca5Al6O14 nanoscale composites by a simple route
and research the photocatalytic activity for crystal violet degradation.

Methods:

Sb2O3/Ca5Al6O14 nanoscale composites were obtained via a simple route using Ca aluminate
nanosheets and Sb acetate. The photocatalytic activity of the Sb2O3/Ca5Al6O14 nanoscale composites
was evaluated using crystal violet as a model pollutant.

Results:

The obtained nanoscale composites consisted of orthorhombic Ca5Al6O14 and orthorhombic
Sb2O3 phases, nanosheets with a thickness of about 50 nm, and nanoparticles with a size of less than
100 nm. Sb2O3 enhanced the light absorption ability of the Ca aluminate nanosheets. The nanoscale
composites with the Sb2O3 content of 20wt.% decreased to 3.03 eV, which is beneficial for improving
the photo-degradation ability of the organic pollutants. The reaction ratio constant k for crystal
violet (CV) degradation was 0.045 min-1 and 0.055 min-1 using the nanoscale composites with Sb2O3
content of 10wt.% and 20wt.%, respectively, which was 1.4 and 1.7 times higher than that of the Ca
aluminate nanosheets (0.032 min-1). Hydroxyl radicals (●OH), hole (h+), and superoxide radicals
(●O2
−) were reaction-active species for CV removal. Sb2O3/Ca5Al6O14 nanoscale composites exhibited
fast interfacial charge transfer and efficient separation ability of photo-induced electron-hole pairs,
which enhanced the photocatalytic activity of the Ca aluminate nanosheets for CV degradation.

Conclusion:

The Sb2O3/Ca5Al6O14 nanoscale composites can be easily separated and reused, showing
great potential for practical application in wastewater treatment.

Published: August 2024

Introduction: This research presents an 8-port 3.6 GHz multiple-input multiple-output
(MIMO) cell phone bezel antenna for 5G mobile communication. Method: Each antenna unit
consists of a Chinese character "卫". In order to reduce the mutual coupling between MIMO
units, a defective ground structure (DGS) decoupling structure is employed in this research. By
increasing DGS in between the antenna, the mutual coupling between adjacent antenna is greatly
reduced. The transmission coefficient and surface current distribution account for the decoupling
structure's efficacy. Result: Simulated and measured results show that the antenna can operate at
Bluetooth/Wi-Fi (2.4-2.483.5 GHz), N77 (3.3-4.2 GHz), N78 (3.3-3.8 GHz), and N79 (4.4-5.0
GHz) frequencies. Conclusion: In addition, the proposed MIMO antenna has excellent diversity
performance, good isolation between antenna units (>15 dB), and envelope correlation coefficient
(ECC) lower than 0.01, due to which the proposed MIMO antenna can be an excellent
choice for 5G cellular communications.

Published: August 2024

Introduction:

In today’s fast-paced world, online shopping has become a staple activity,
especially for busy individuals seeking convenience. Online shopping has emerged as a
predominant activity, particularly popular among the younger demographic. The hectic lifestyles
of the working class have elevated online shopping to a convenient and often essential
practice, providing a respite amidst their busy schedules. Simultaneously, businesses in the
competitive E-commerce market recognize the importance of understanding customer behavior
and perceptions to foster loyalty and ensure sustainability.

Method:

In response to the evolving landscape of online shopping, we have undertaken a comprehensive
analysis using machine learning techniques. Our approach involves the utilization of
machine learning algorithms to recognize patterns and make precise predictions. We divide
the data set into quarters, assess sales income per quarter, and further partition the data into
training and testing sets. The subsequent steps involve forecasting revenue for upcoming
quarters and identifying top-performing commodities to devise a Python-based model for strategic
customer retention. The methodology begins by segregating the sales data set into quarters,
followed by the calculation of quarterly sales income. Using a machine learning system,
our approach forecasts revenue for future quarters and identifies high-performing commodities
based on quarterly sales rates.

Result:

The culmination of these results leads to the development of a Python-based model for
strategic customer retention. The outcome of our analysis not only facilitates precise predictions
of future revenue but also contributes to the creation of a strategic model for customer retention.

Conclusion:

By identifying high-performing commodities and leveraging machine learning
algorithms, we establish a symbiotic loop of sales and purchasing between customers and
the E-commerce company. This algorithmically-driven loop promises incremental profitability
for both the customers and the E-commerce company, creating a symbiotic relationship.
