Published: March 2023

Abstract

Purpose: To retrospectively evaluate the children who were suspected to have a retrocaval ureter during management for urinary tract dilation. Retrocaval ureter may be missed or misdiagnosed due to rare incidence. Fish-hook sign is a particular radiological sign that may indicate retrocaval ureter but sensitivity and specificity are not discussed previously. Materials And Methods: The children (n=12) in whom retrocaval ureter was considered in the differential diagnosis between 2016 and 2022 are enrolled in the study. The demographics of the patients, findings suggesting retrocaval ureter, evaluation process, management, and final diagnosis are retrospectively evaluated.
Results: The final diagnosis was retrocaval ureter (n=3), ureteropelvic junction obstruction (n=7), and duplicated collecting system (n=2). A retrocaval ureter was confirmed or excluded by ultrasonography while there was a stent in the ureter in 6 patients and by laparoscopic exploration in the rest 6 patients. Three underwent surgery for RCU, 8 for uretero-pelvic junction obstruction, 1 for reflux and 1 ureterocele puncture.
Discussion and Conclusion: Fish-hook sign is a rare conflicting finding that can be encountered on imaging studies. This uncommon finding needs confirmation or exclusion of a possible retrocaval ureter. Radiological evaluation (by ultrasonography or cross sectional studies) while there is a stent in the ureter is the most satisfactory way to confirm or exclude a retrocaval ureter. Alternatively, being aware of a possible retrocaval ureter and performing a little more extensive dissection may be necessary during surgery to confirm or exclude it. If available, laparoscopy may provide this goal in a minimal invasive manner with superior visualization .
Soil moisture influences the root characteristics of a herbaceous riparian plant along a regulated river
Authors: DENG XIAO , Greet Joe , Jones Christopher S. 
Published: March 2023

Abstract
River ecosystems of regulated rivers are threatened by water extraction and flow regime alteration in the context of climate change and increasing human populations. Riparian plant root growth is important to sustain plant health and provide functions including bank stabilization. The root systems of riparian plants on regulated rivers may suffer from lower soil moisture due to lack of natural flow variability. This study aimed to evaluate how soil moisture influences the root system of a herbaceous riparian plant. Plants of Juncus amabilis were dug out along a soil moisture gradient, corresponding with positions close to or distant from the water margin and low or high relative bank elevation. Root depth, belowground space occupation, root mass fraction and mean fractal dimension were used to evaluate root structural dynamics in relation to bank position and soil moisture. The ratio between root and aboveground dry weights of sampled plants was constant over the elevation range sampled. Plant root systems tended to grow deeper, occupy more belowground space, and have fewer branches as soil moisture declined. These findings indicate that lower soil moisture levels and reduced river flows may significantly influence herbaceous riparian plant growth and survival. Riparian plant health and function will likely be promoted by flow regimes that provide adequate and timely water delivery.

Abstract
The present study was performed with the gut tissue of early juvenile (EJv) (body weight range between 40-70g) and late juvenile (LJv) (body weight range between 200-300g) carp, Catla catla, to address three queries. First, to search for any variations in the levels of gut melatonin, oxidative stress levels, its management, and vital digestive enzymes between the EJv and LJv carps. Second, to understand the response of dietary supply of protein-, L-tryptophan-, carbohydrate-, and oil-rich diet on the levels of melatonin concentration, oxidative stress, antioxidative agents, and activity of major digestive enzymes in the gut. Third, to comprehend the role of gut melatonin in managing oxidative stress and modulating the digestive capacity. Data analysis revealed that gut melatonin concentration is higher in EJv carp and lower in LJv carp, while feeding intensity was the reverse. The L-tryptophan and protein-rich diets exhibited stimulatory but different responses to gut melatonin, amount of residual gut content and feeding intensity between the EJv and LJv carps. Substantial evidence was recorded on the role of gut melatonin in regulating stress, levels of antioxidative agents, and vital digestive enzymes, particularly in protein and microbial digestion. Nonetheless, the current study reports for the first time that the nature of gut melatonin synthesis, feeding intensity, generation of oxidative stress, defense by different antioxidants, and digestive capacity vary in LJv carp from its EJv stage. Further, such variations may also be modulated by the dietary components of fish feeds, particularly by the protein or L-tryptophan enrich fraction.

Published: March 2023

Abstract
Purpose
The pre- and post-operative variation of neutrophil to lymphocyte ratio is reportedly related to postoperative prognosis. This research was undertaken to evaluate the potential of ΔNLR= (ΔNeutrophil to lymphocyte ratio = postoperative extreme neutrophil to lymphocyte ratio - preoperative neutrophil to lymphocyte ratio) to predict the prognosis based on its relationship with overall survival and relapse-free survival in patients with rectal cancer treated with radical operation.
Methods
This study was single institution retrospective study that conducted in colorectal surgery at a tertiary teaching hospital. The 584 patients with pathologically confirmed rectal cancer and treated with primary tumor resection between 2012 and 2014 in a single university-affiliated tertiary academic hospital were involved. To assessment the veracity of ΔNLR for rectal carcinoma prediction, a receiver operating characteristic curve was plotted. Patients were divided into two groups, high and low ΔNLR, according to the optimal cutoff value. The proportional risk regression model was performed univariate and multivariate analysis for rectal carcinoma prediction.
Results
Multivariate analysis showed that a high pretreated serum carcinoembryonic antigen ( p = 0.005), Tumor stage ( III VS I( p < 0.001), II VS I( p = 0.006)), chemotherapy ( p < 0.001) and ΔNLR ( p = 0.002) was an independent prognostic factor for poor overall survival.
Conclusion
Our research shows that the ΔNLR might be a prognostic marker in RC patients with operative treatment.
Clinical attire preference among patients in military healthcare facilities in Kuwait
Authors: Albagdady Mohammad , Alotaibi Hazza , Sadek Ali Ahmad , Hands Joanne , Alali Ahmad , Alsabah Abdullah Meshal 
Published: March 2023

Abstract
Objectives
Military healthcare professionals often consult patients while wearing their full military uniforms, which may affect patients’ clinical experience. This study aims to understand patients’ opinion concerning clinicians’ attire with regard to patients’ preference, ease in declaring personal or private information, comfort in asking for further information or raising concerns, and confidence in maintaining privacy and confidentiality in a military setting.
Methods
Patients attending outpatient clinics in two military medical facilities in Kuwait were asked to complete a questionnaire regarding their preference for clinician attire and any effect on their comfort or confidence in the clinicians. The study took place in 2021.
Results
The overall response rate was 94.6% (n = 937). Most participants were neutral regarding all statements. However, female participants preferred their doctors to be in military uniforms in comparison with males (P = 0.000). Non-Kuwaiti participants felt more comfortable sharing private/personal information and asking for clarification or raising concerns with a doctor in military uniform (p = 0.007). Civilian participants also preferred doctors in military uniform (p = 0.000). Officers preferred their doctor to be in military uniform (p = 0.014), whereas non-commissioned officers preferred their doctor to be in civilian attire (p = 0.000).
Conclusion
Patients visiting military medical facilities do not prefer a certain attire, and attire does not influence their perception of the physicians’ competence. This may lead us to conclude that doctors’ attire, regardless of being civilian or military, may not be the most concerning factor regarding the patient’s confidence and comfort and that the doctor-patient relationship is more vital. Therefore, further investigation of the psychological impact of doctor’s attire is highly recommended.
Petrography and Diagenesis of Neoproterozoic Bhander Sandstones of Bundi-Indergarh area, Vindhyan Supergroup, Southeastern Rajasthan, India: Implication for Provenance and Reservoir characteristics
Authors: Ayaz Tahreer , Hasan Mujeebul , Khan Abdullah 
Published: March 2023

Abstract
The Neoproterozoic Bhander Group, the youngest and most widely distributed group of Upper Vindhyans, consists of about 1000m thick succession of sandstone, shale, and limestone. Petrographic investigations reveal that the Bhander Sandstones are mineralogically mature and classified as quartzarenite and sublitharenite type which is composed of varieties of quartz with ultra-scarcity of feldspar, lithic fragments, micas, and heavy minerals. Average framework composition of the Lower Bhander Sandstone is Qt98.68F0.10L1.22 and Upper Bhander Sandstone is Qt95.92F0.12L3.96. Quartz is a more abundant mineral, as shown by X-ray Diffraction Analysis. Petrofacies reveal that the Bhander Sandstones were derived mainly from the source rocks of a craton interior setting with a minor quartzose recycled sedimentary source material. A scarcity of feldspar and rock fragments suggests intense chemical weathering in a warm and humid paleoclimate. Mechanical compaction, cements, authigenic clays, and dissolution and modification of unstable clastic grains are the major diagenetic components identified based on the framework grain-cement relationships. Kaolinite and silica (quartz) overgrowth are found as pore-filling and lining cements. Compaction was more effective than cementation in affecting primary porosity. Cementation decreased porosity and permeability drastically. Kaolinite fills pore spaces, reducing the sandstone's porosity and permeability. Secondary porosity developed as a result of partial to complete feldspar dissolution. The diagenetic signatures observed in the Bhander Sandstones are suggestive of deep burial. The reservoir quality of the studied sandstones is degraded by authigenic clay minerals and cementations, but enhanced by alteration and dissolution of unstable grains.
An Ensemble-based Predictive Model for Examine Chronic Kidney Disease
Authors: Nagalpara Sirajbhai , Patel Bhavesh 
Published: March 2023

Abstract
Chronic Kidney Disease (CKD) is a chronic ailment that involves a gradual decline in kidney function over time and lose their function over time. The focus of the research was to determine the most suitable classification algorithm for the diagnosis of CKD based on its classification report and performance factors. One approach to enhancing the accuracy of predictions is to combine multiple models such as Random Forest and Adaboost classifier were analyzed instead of relying on a single model. To put it another way, using an ensemble of models can lead to better predictive performance compared to using a single model alone. The results of the experiment showed that the stacking algorithms performed better than the other algorithms, producing an accuracy rate of 100.00%.

Published: March 2023

Abstract
Most of the current task-oriented dialogue systems (ToD), despite having interest-ing results, are designed for a handful of languages such as Chinese and English.Therefore, their performance in low-resource languages is still a significant prob-lem due to the absence of a standard dataset and evaluation policy. To addressthis problem, we proposed ViWOZ, a fully-annotated Vietnamese task-orienteddialogue dataset. ViWOZ is the first multi-turn, multi-domain, task-orienteddataset in Vietnamese, a low-resource language. The dataset consists of 5,000dialogues in total, including 60,946 fully annotated utterances. Furthermore, weprovide a comprehensive benchmark for both modular and end-to-end models inlow-resource language scenarios. With those characteristics, the ViWOZ datasetenables future studies on the construction of multilingual task-oriented dialoguesystems.
Non-separation method-based global stability criteria for Takagi-Sugeno fuzzy quaternion-valued BAM delayed neural networks using quaternion-valued auxiliary function-based integral inequality
Authors: Ramalingam Sriraman , Kwon Oh-Min 
Published: March 2023

Abstract
This paper examines the global asymptotic stability of Takagi-Sugeno fuzzy quaternion-valued BAM neural networks with discrete, distributed and leakage delays using non-separation method. By applying Takagi-Sugeno fuzzy models , we first consider a general form of Takagi-Sugeno fuzzy quaternion-valued BAM neural networks with time delays. Then, we apply the Cauchy-Schwarz algorithm and homeomorphism principle in order to establish the existence and uniqueness of the equilibrium point. By using appropriate Lyapunov-Krasovskii functionals and quaternion-valued auxiliary function-based integral inequality, we derive new delay-dependent global asymptotic stability conditions for the considered neural networks. Furthermore, we present our results in terms of quaternion-valued linear matrix inequalities that can be solved in the MATLAB YALMIP toolbox. To demonstrate the validity of the theoretical analysis, we provide two numerical evaluations with simulations.

Published: March 2023

Abstract
The widespread existence of weak interlayer poses a serious threat to the stability of roadway surrounding rock under constant stiffness restraint boundary condition in lateral direction (axial direction of roadway) and the rock bolt is widely used to reinforce the surrounding rock of roadway. So, in this paper, the reinforcement performance of the bolted rock mass with a weak interlayer was investigated under constant lateral stiffness (CLS) boundary condition. The research results indicated that the peak strength and elasticity modulus of the samples exponentially increase with the increasing of bolt pretension force and density. Two parameters Rp and RE were put forward to quantitatively describe the reinforcement effect of bolt pretension force and density on the peak strength and elasticity modulus of the samples. Under CLS boundary condition, the lateral direction of the samples experienced loading-unloading and expansion - compaction deformation periods during the whole triaxial compression process. The mechanism for the transformation of expansion - to - compaction was explained. Two new failure modes of the samples were observed and analyzed in detail, and were found them different from those of the bolted jointed rock mass and bedded rock mass.

Published: March 2023

Abstract
Purpose
The preoperative diagnosis of thyroid nodules now routinely includes BRAFV600E genetic testing in most provincial and municipal hospitals in China. This study identified the most suitable patients of thyroid nodule for BRAFV600E genetic testing.
Methods
We retrospectively collected data of patients from the Hospital Information System that had undergone fine needle aspiration biopsy (FNAB) from May 2019 to December 2021. Data of FNAB, BRAFV600E genetic testing, and post-surgical pathological diagnosis were collected.
Results
A total of 12,392 patients were included in this study. Among them, 7,010 patients underwent solely FNAB, while 5,382 patients had both FNAB and BRAFV600E genetic testing. In the FNAB group, 2,065 thyroid nodules were surgically removed, with a 93.12% malignancy rate. In the FNAB + BRAF group, 2,005 nodules were dissected, and the malignancy rate was 98.20%. However, it was evident that in the subgroups, the combination of FNAB and BRAFV600E genetic testing only benefited Bethesda III (p < 0.001) and V (p = 0.001) nodules.
Conclusion
Overall, the combination of FNAB with BRAFV600E genetic testing significantly improved the malignancy rate of surgical thyroid nodes at our hospital when compared to FNAB alone. The subgroup analysis showed that BRAFV600E genetic testing only benefited Bethesda III and V nodules. These findings provide a clinical reference for rationally selecting the most suitable population for BRAFV600E genetic testing.
An Analytical Study of the Effect of Gravity on Electronic Wavefunctions in Oxygen
Authors: Saraswat Rushil 
Published: March 2023

Abstract
We can determine the presence of oxygen in the sun by observing its absorption spectrum. However, no single wavelength observed in the oxygen spectrum of the sun directly corresponds to the Ritz wavelength of either the oxygen atom or the oxygen molecule. To account for this inconsistency, the study hypothesizes that the shells of the oxygen atom expand or compress under the presence of gravity, and it causes the change of difference in energy levels. To verify the hypothesis, the study assumes the shells in the atom to be different levels of a modified version of an infinite potential well. The relative distance between two shells of atoms present on the earth and the sun can be worked out by comparing the energies of the modified infinite potential wells. The study finds that the ratio of distances between the atoms present on the earth and the sun is not same, hence, verifying the hypothesis. To further verify the hypothesis, analysis of spectrums of more elements under the influence of a large gravitational field and with significant screening effects is required.

Published: March 2023

Abstract

The development and rapid adoption of virtual reality (VR) have brought with it the need to redefine the concept of quality of user experience (QoE). To date, QoE models for VR have provided us with a narrow view of the concept, traditionally operating under the umbrella of a single discipline (e.g., psychology) or a specific feature of the user experience (e.g., presence). Moreover, literature reviews on the topic have focused on academic articles disregarding the constant technological updates reflected in industry reports. Addressing these gaps, the current study adopted a rigorous, integrative literature review approach. The results of 729 sources were analysed to outline and describe 252 factors divided into four main branches (i.e. user, system, context and content). Finally, a comprehensive multidisciplinary model was created based on representative academic and industry sources from the fields of psychology, communication sciences, ergonomics, computer science and technological innovation. Notably, an interactive dashboard that outlined in detail the facets of the model was developed. The dashboard presents scholars and developers with a practical tool that aids the design of future experiments and the development of VR products. Ultimately, the extensive scope and laborious state-of-the-art methodology of the current paper present significant value to academia and industry alike.

Abstract
Background
Menarche is a key indicator of puberty and is influenced by a variety of variables, including socioeconomic status and their residence. To provide health services and menstrual health education to schoolgirls, health policymakers must be aware of the menarche age. Here in we aimed to investigate the timing of menarche in secondary school girls and its associations with socioeconomic status and body mass index.
Methods
A cross-sectional study enrolled 130 girls carried out from January to march 2023 in secondary schools in Shabasha City, White Nile State, Sudan. Structured questionnaires were used to gather the personal information from the girls and parents, age at menarche, and factors influencing age at menarche, height, and weight.
Results
The mean age of girls was 16.5 ± 1 years while the mean age of menarche was found to be 13.6 ± 1.3 years, and the majority of the girls had menarche age of 14 years 44(33.8%) and 13 years 42(32.3%). Mothers (n = 86; 66.2%), sisters or friends (n = 84; 64.6%), and teachers (n = 81; 62.3%) were the main advisors. Also, examinations were the main stressor in 12(9.2%) girls. The age of menarche was found to be negatively correlated with BMI (r= -0.365; P. value = 0.027), and underweight girls had a later age of menarche (14.81.4 years; P. value = 0.000). Furthermore, girls with low socioeconomic status had menarche at a later age (14.61.3 years). Menarche occurred later in girls who lived with their father alone (14.31.6 years) and with their mother alone (140.5 years). The age of menarche had no effect on parental education, family size, or stressors (P value > 0.05).
Conclusion
The age of menarche among schoolgirls was found to be relatively similar to that reported in Sudan and other countries in the region. It was significantly related to the girls' BMI, socioeconomic status, and the types of residents.
Therapeutic and Diagnostic Agents based on Bioactive Endogenous
and Exogenous Coordination Compounds
Authors: Kostova Irena 
Published: March 2023

Abstract:
Metal-based coordination compounds have very special place in bioinorganic
chemistry because of their different structural arrangements and significant application in
medicine. Rapid progress in this field increasingly enables the targeted design and
synthesis of metal-based pharmaceutical agents that fulfill valuable roles as diagnostic or
therapeutic agents. Various coordination compounds have important biological functions,
both those initially present in the body (endogenous) and those entering the organisms
from the external environment (exogenous): vitamins, drugs, toxic substances, etc. In the
therapeutic and diagnostic practice, both the essential for all living organisms and the
trace metals are used in metal-containing coordination compounds. In the current review,
the most important functional biologically active compounds were classified group by
group according to the position of the elements in the periodic table.
