Naltrexone (NTX), a homologue of the opiate antidote naloxone, is an orally active long-acting mu-opioid receptor (MOP) antagonist used in the treatment of opiate dependence. NTX is also found to relieve craving for alcohol and is one of the few FDA-approved drugs for alcohol use disorder (AUD). Reports that NTX blocks the actions of endogenous opioids released by alcohol are not convincing, suggesting that NTX interferes with alcohol actions by affecting opioid receptors. MOP and kappa-opioid receptor (KOP) are structurally related but functionally different. MOP is mainly located in interneurons activated by enkephalins while KOP is located in longer projections activated by dynorphins. While the actions of NTX on MOP are well established, the interaction with KOP and addiction is not well understood. We used sensitive fluorescence-based methods to study the influence of alcohol on KOP and the interaction between KOP and NTX. Here we report that alcohol interacts with KOP and its environment in the plasma membrane. These interactions are affected by NTX and are exerted both on KOP directly and on the plasma membrane (lipid) structures (“off-target”). The actions of NTX are stereospecific. Selective KOP antagonists, recently in early clinical trials for major depressive disorder, block the receptor but do not show the full action profile of NTX. The therapeutic effect of NTX treatment in AUD may be due to direct actions on KOP and the receptor environment.

A novel Al2O3/(Y0.2Er0.2Yb0.2Ho0.2Lu0.2)3Al5O12((5Re0.2)AG)/ZrO2 eutectic high entropy oxide ceramic composites (HEOCs) was prepared by the directional solidification technique. The Al2O3/(5Re0.2)AG/ZrO2 eutectic HEOCs had a refined microstructure and different crystallographic orientation relationships of < 10–10 > Al2O3 || <103>(5Re0.2)AG || <100 > ZrO2, {11–20}Al2O3 || {100}(5Re0.2)AG || {100}ZrO2, {0001} Al2O3 || {103}(5Re0.2)AG || {100}ZrO2 compared to Al2O3/YAG/ZrO2 eutectic ceramic composites. ZrO2 in the Al2O3/(5Re0.2)AG/ZrO2 eutectic HEOCs was distributed more uniformly and dispersedly than in Al2O3/YAG/ZrO2 eutectic ceramic composites due to the similar volume strain of Al2O3/(5Re0.2)AG, (5Re0.2)AG/ZrO2 and Al2O3/ZrO2. As a result, mechanical performance including hardness, elastic modulus, and fracture toughness had been greatly improved because of the refined microstructure, tailored interfacial structure, and homogeneous distribution of ZrO2 caused by the introduction of the high entropy (5Re0.2)AG.

Published: July 2023

Tobacco leaf grading is an essential step for the rational use of tobacco resources and enhancing tobacco benefits. However, the existing tobacco leaf grading technology suffers from the problem of limited grade discrimination and low identification accuracy of single classifiers. To address these issues, we proposed a tobacco leaf grading method based on Whale Optimization Algorithm and multi-heterogeneous classifier Stacking ensemble (WOA-Stacking). In this paper, we utilized the differences in data observation and training principles of heterogeneous classifiers and integrate them using the Whale Optimization Algorithm (WOA) to build a stacked ensemble model. The fitness function is calculated based on the classification performance matrix and the discriminant function. The optimal combination of base classifier and meta classifier is selected from the classifier pool composed of 9 heterogeneous classifiers, and a data-driven classification model is constructed. Subsequently, hyperparameter tuning and hierarchical coupling are performed by Grid Search (GS) and K-fold Cross-Validation (K-CV). Finally, the model is evaluated and validated by applying the tobacco leaf grade dataset. The experimental results demonstrate that the WOA-Stacking model outperforms traditional single classification models, and achieves high accuracy in tobacco leaf grade classification. The model constructed in this paper can be applied as a data-driven general model for tobacco leaf grade classification in different regions, providing technical support towards industrialization of tobacco leaf grading.

Authors: Gebretsadik Solomon , Yemane Betelhem , Adraro Zerihun
Published: July 2023

Background: Vitamin A supplementation has been shown to reduce risk of death in under 5 children by about 23%-30% .Guaranteeing a high coverage of supplementation is therefore critical, not only to eliminating vitamin A deficiency as a public health problem but also as a central elements of the child survival agenda. The purpose of this study was to assess vitamin A supplementationstatus and associated factors among children 6-59 months of age at Akaki Kality sub-city, Addis Ababa, Ethiopia.
Methods: A community-based cross-sectional study design was applied among children 6-59 months of age in Akaki Kality sub city from23rd of March to 15th of April, 2021. A multi-stage sampling, followed by a systematic sampling technique was employed to select study participants. A structured interviewer administered questionnaire was used to collect data. A binary logistic regression model was used to identify factors associated with vitamin A supplementation. The adjusted odds ratio with a 95 % confidence interval was computed to assess the strength of the association, and variables with a p-value of less than 0.05 in multivariable analysis were considered as statistically significant.
Result: The result revealed that vitamin A supplementation coverage among children age 6 to 59 months was 59.5%.Women educational status (AOR=5.590; 95%CI: 2.179-14.343), household monthly income (AOR=0.322; 95% CI: 0.163-0.637), having information about VAS (AOR=5.811; 95% CI: 3.448-9.794) and child age (AOR=0.286; 95% CI: 0.133-0.613)were statistical significantly associated (p-value less than 0.05) with vitamin A coverage.
Conclusion: The vitamin A supplementation coverage in the study area was low which is far from the expected national target. Women education and monthly income were positively associated, but the children age was inversely associated with vitamin A coverage. Hence, different effort has to be applied like awareness creation through community education and improving socio-economic status of the community to enhance the coverage of vitamin A supplementation coverage.

Published: July 2023

Background: This article is the first to present a national level mapping of the provision of mental health services to young people living in Colombia. It explores the existing public mental health provision in the country, with a particular focus on where mental health resources are concentrated.
Methods: This research adopted a mixed methodology including: 1) a documentary policy analysis to understand youth mental health provision; 2) interviews with key policy makers and stakeholders responsible at the national level for policy delivery and implementation; and 3) a quantitative analysis of three key datasets to understand the resources available for youth mental health within Colombia.
Results: We use this mapping to understand how the current mental health system in Colombia fits with international approaches to youth mental health and find that whilst mental health disorders presented a significant portion of the global disease burden, particularly in low-income countries, approaches to supporting population level youth mental health have not been adapted for conflict contexts. This paper addresses that gap through a detailed review of documentation, interviews with key stakeholders and a quantitative analysis of existing data on mental health and suicide across Colombia.
Mental health was framed (biomedical, biosocial, psychologically or through human rights), Colombian policy clearly focusses on a differential approach that shapes service provision to target support at those in need, but consequently neglects whole population level mental health support. This means that not all stakeholders were clearly articulated or included in policy and key stakeholders, such as education, were not linked to implementation plans or activity. Policy approaches were also over-centralised with little cross-institutional collaboration.
Conclusion: Youth were specifically missing from services, as was explicit understanding the intergenerational effects and impact of conflict. This was exacerbated by unequal distribution of mental health care services concentrated in populous, urban areas away from conflict-affected regions. Suicide is the second most prevalent cause of death with 10% of population who were recorded as dying by violence, dying from completed suicide. Triangulation of this data implies a strong relationship between suicide and poorer access to professional support in conflict-affected areas.

Published: July 2023

Background
Malignant uterine cervical neoplasms continue to be the fourth leading cause of cancer-related mortality among women globally. There is a growing interest in the prognostic value of routinely performed pre-treatment blood test indices such as red cell distribution width (RDW) or systemic immune-inflammation index (SII), the latter combining neutrophils-to-lymphocyte ratio (NLR) and platelets-to-lymphocyte ratio (PLR). These indices were shown to be prognostic for survival in some malignancies. The purpose of the study was to evaluate the association between pre-treatment RDW and SII, and overall survival (OS) in patients treated with radiotherapy for primary localised cervical cancer.
Methods
This retrospective analysis included patients treated with definitive chemoradiation therapy (CRT) between 2011 and 2017 for histopathologically confirmed FIGO 2018 stage IB2-IVA cervical cancer. Statistical analysis was performed using the Kaplan-Meier method, two-sided log-rank tests, and Cox proportional hazards models, with the Akaike Information Criterion (AIC) serving as a prediction error estimator.
Results
The study group included 249 patients with a median age of 57.2 years and a median follow-up of 75.8 months. The majority were diagnosed with squamous cell carcinoma (237, 95.2%) and had FIGO stage III (211, 84.7%). Approximately half of the patients (116; 46.4%) had regional lymph node metastases.
Patients with low RDW (≤13.4%) and low SII (≤986.01) had a significantly longer OS (p=0.001 and p=0.002). The RDW remained as an independent prognostic factor in the multivariable model (high vs low; HR=2.04; 95%CI: 1.32-3.16; p=0.001). Including RDW in the model decreased Akaike Information Criterion from 1028.25 to 1018.15.
Conclusions
RDW is a cheap and widely available index that is simultaneously an independent prognostic factor for survival and could be used to improve pre-treatment prognosis assessment in cervical cancer patients undergoing CRT. Available data encourages assessing RDW as a prognostic factor in prospective trials to aid identification of candidates for treatment escalation.

Authors: Dehkordi Shiva Moazen , Mohammadi Hamidreza
Published: July 2023

An array of metallic nanoparticles can diffract or concentrate the incident electromagnetic wave and hence behaves as an antenna. In this paper, the effects of inner sub-wavelength structure of nanoparticles is studied on the directivity of the plasmonic nanoantenna which is coated on the output of a waveguide. The results show that structured nanoantennas can improve the directivity of the antenna due to the hybridization mechanism. The resuls may be useful for designing and fabricateing directive optical fibers endcaps.

Published: July 2023

Background
Alzheimer's disease is described as a structural and functional disorder of the human brain and its prevalence is increasing among middle-aged communities. Inflammation is one of the most important key factors in the development of Alzheimer's. IL-33, as a multifunctional cytokine, can play a significant role in Alzheimer's-induced inflammation. This study was performed to evaluate the anti-inflammatory properties of propolis On IL-33 gene expression. It is also designed to observe its effect on memory and learning in groups of laboratory rats.
Methods
To evaluate the learning and movement ability of the animals the passive avoidance learning, and locomotion tests were carried out after injection of scopolamine and propolis in third and fourth groups. Then, the morphologic changes and density of survival neurons counting have been assessed using histopathological analysis and following on, Real-Time PCR was applied to investigate the anti-inflammatory effect of propolis on the expression level of IL-33 mRNA in samples.
Results
Our study showed the treatment of animals using propolis led to an increase in learning and movement ability compared to the Alzheimer group. Besides, the histopathological evaluation demonstrated that the number of survival neurons were significantly more than Alzheimer group in hippocampal CA1 area, although the existing lesions was similar in both groups. The treatment of animals by propolis also resulted in a considerable increase in the expression of IL-33 in comparison with other groups.
Conclusion
In general, it seems that the application of propolis, as an anti-inflammatory compound, could be considered as a remarkable impact on Alzheimer improvement by both accelerations of IL-33 expression and learning ability. However further studies are needed to determine the exact mechanism and efficacy of this agent for the people suffer from Alzheimer.
Anomalous origin of the circumflex coronary artery from the pulmonary artery: a case report
Authors: Donné Marieke , Vandekerckhove Kristof , Drieghe Benny , François Katrien , Panzer Joseph
Published: July 2023

Case description:
A 4-year old boy without significant prior history, presented with pronounced dyspnea. During clinical examination only mild hepatomegaly was present. Thoracic radiography showed significant cardiomegaly. Echocardiography revealed left ventricular dilatation and poor systolic function. Both Troponin and NT-pro-BNP level were elevated. Treatment with diuretics and inotropics was started with clinical improvement. The diagnosis of an anomalous left circumflex artery out of the right pulmonary artery was suspected by coronarography and confirmed by coronary CT. Coronary reimplantation was performed without complications. Subsequently, left ventricular dimensions normalized progressively in the next months.
Discussion:
Without congenital heart disease, an anomalous left circumflex artery arising from the pulmonary artery is rarely present. Symptoms and prognosis are determined by the amount of collateral circulation to provide adequate myocardial perfusion. Diagnosis of an anomalous left circumflex artery (LCx) is mostly made at adult age. However, our patient presented at young age. Even though the origin of both coronary arteries was normal, a coronary anomaly lies at the origin of his cardiac dysfunction. Treatment consisting of surgical reimplantation or coronary bypass is the primary choice.
Conclusion:
We present this case to highlight the importance of having a high index of suspicion of coronary artery abnormalities in children with dilated cardiomyopathy, as the prognosis can be very favorable after surgical repair. Transthoracic echocardiography is not always conclusive in showing a normal origin of both coronary arteries and certainly not for visualizing the LCx reliably. Therefore, further imaging should be considered in children with a new diagnosis of unexplained DCM.

Published: July 2023

Most residential and institutional centers in urban areas provide on-site sanitary facilities for waste management, such as septic tanks and conventional pit latrines, to collect and dispose of the generated human wastes. The most difficult problem in Bahir Dar City is the influence of these human waste management sanitary structures on groundwater quality, which has recently become a major concern in most developing countries, including Ethiopia. Twelve (12) shallow groundwater wells were selected purposively throughout the city in order to assess the pollutant concentration and its impact on groundwater quality. Temperature, pH, turbidity, electrical conductivity (EC), total dissolved solids (TDS), chloride, nitrate, phosphate, total hardness, and Escherichia coli (E. coli) were all measured in the collected groundwater samples both in situ and in the lab. To determine pollutant sources and levels of compliance with particular water quality criteria, differences in groundwater quality parameters between the measured stations were examined. In all sampled stations, the study's overall findings revealed that E. coli concentration levels exceeded the WHO threshold, and shallow wells next to on-site waste management facilities are completely contaminated. The results of this study will generally aid in the future development of the best groundwater quality management strategies and methods for implementing corrective actions to avoid groundwater quality issues.
Advancing Soil Image Classification through Comprehensive Evaluation for Crop Suggestion
Authors: R Chetan , Ashoka D V , V Ajay Prakash B
Published: July 2023

Soil image classification is an important task in agricultural and environmental applications. With the advent of deep learning, image-based soil classification has become a popular research topic. Transfer learning is a widely used approach in image classification, where a pre-trained model is fine-tuned on a new dataset. However, traditional transfer learning approaches only fine-tune the last layer of the pre-trained model, which may not be sufficient for achieving high performance on a new task. In this paper, we propose HybridTransferNet, a novel hybrid transfer learning approach for image-based soil classification. HybridTransferNet fine-tunes a small number of earlier layers in addition to the last layer of a pre-trained ResNet50 model, resulting in improved classification performance compared to traditional transfer learning approaches. We evaluate HybridTransferNet on a soil classification dataset and report multiple performance metrics, including accuracy, precision, recall, and F1 score. Our experimental results show that HybridTransferNet outperforms traditional transfer learning approaches and achieves state-of-the-art performance on the soil classification task.

Introducción: El huevo, uno de los principales alimentos que aporta nutrientes a la población mundial, pierde su calidad de forma acelerada en estado fresco.  Para la industria del huevo sería beneficioso contar con alternativas tecnológicas que permitan aumentar su vida útil, como la utilización de recubrimientos para prevenir su deterioro. Objetivo: Evaluar el efecto de la aplicación de recubrimientos de aceite sobre la calidad fisicoquímica, microbiológica y sensorial de huevos de gallina en almacenamiento. Métodos: Por inmersión, aplicamos recubrimientos de aceite mineral grado medicinal desodorizado o de oleína de palma y soya con TBHQ 0,02% a huevos de gallina Isa Brown categoría A de un productor local, sin previa limpieza, lavado o desinfección.  Luego de dejar escurrir por 6 horas los almacenamos en una cámara a 21°C y 43% HR. Medimos los parámetros de calidad seleccionados cada 7 días por un total de 42 días y comparamos estadísticamente las tendencias en el tiempo para los huevos recubiertos y sin recubrimiento.  También realizamos un análisis sensorial mediante comparaciones pareadas para huevo fresco y huevo recubierto almacenado por determinado tiempo y una medición de aceptación general por medio de una escala hedónica a los 35 días de almacenamiento. Resultados: Los recubrimientos evaluados no afectaron el comportamiento normal del color y pH de la yema, las unidades Haugh, la resistencia a la ruptura y los recuentos total aerobio y de mohos y levaduras durante el almacenamiento, al tiempo que retardaron el deterioro relacionado con el índice de yema, el pH de la clara y la pérdida de masa. Además, la aplicación de dichos recubrimientos permite mantener la percepción del sabor del huevo almacenado al compararlo con huevo fresco; provee huevos con el mismo olor y adhesividad que el huevo sin recubrimiento; otorga brillo y no influyen negativamente en su aceptación sensorial externa.  Conclusión: La vida útil del huevo durante su almacenamiento puede alargarse con la aplicación de recubrimientos de aceite mineral o de palma.
