Hirsutism as the initial presentation of malignant ovarian Leydig cell tumor: A case report
Authors: Arafat Hasan , Khaldy Marah , Abu Munshar Ahmad , Zughayyer Amer 
Published: October 2023

AbstractOvarian steroid cell tumors are a rare subtype of sex‐cord stromal cell tumors. Overall, these tumors make <0.1% of all ovarian tumors. These neoplasms can be divided according to the cell of origin into stromal luteomas, Leydig cell tumors, and steroid cell tumors not otherwise specified. These tumors can be benign, malignant, or borderline, with variable presentation. We report a case of 24‐year‐old virgin female who was referred to our hospital after being diagnosed with steroid cell tumor‐not otherwise specified. Prior to her admission, the patient had been treated unsuccessfully with oral contraceptive pills due to male‐pattern facial hair growth, abdominal cramps, and irregular menstrual cycle. Lack of improvement warranted further investigations. Hormonal studies showed an elevated total testosterone, dehydroepiandrosterone sulfate, and morning fasting cortisol. Ultrasonography and computed tomography confirmed the presence of a large pelvic mass with mixed solid and cystic component. Therefore, unilateral salpingo‐oophorectomy was performed. Pathological and immunohistochemical examination suggested the presence of a large ovarian steroid cell tumor‐not otherwise specified with malignant behavior. The patient did not receive adjuvant therapy and developed metastatic disease. She received four cycles of BEP protocol with no improvement, so she was referred to our center to continue oncological management. Case revision confirmed the presence of steroid cell tumor, but of a different subtype: Leydig cell. She received six cycles of carboplatin‐paclitaxel, but her assessment showed disease progression. We report this case with review of literature regarding the appropriate approach to these rare tumors. Although rare, ovarian steroid cell tumors should be included in the differential diagnosis of virilization in young females, especially those refractory to hormonal therapy. In our study, we aimed to present the first reported Palestinian case, which highlights the importance of detailed morphological examination in addition to the difficulties encountered to reach a proper diagnosis. We also provided a review of the existing literature regarding chemotherapeutic lines used in such cases and the response to each.

AbstractThis study analyzed trends across five decades of productivity data from the Louisiana Sugar Industry, from 1969 to 2021, for sucrose content, cane yield, and sugar yield. Trends over the five decades were revealed using robust regression models, and the least square means allowed for decade‐wise comparisons of trends. Sucrose content increased 45%, from 80.9 ± 6.4 g kg−1 in the first (1969–1979) to 116.7 ± 4.8 g kg−1 in the fifth (2010–2021) decade, at 0.85 ± 0.06 g kg−1 per year. Cane yield increased slower (32.2%), from 57.7 ± 5.9 Mg ha −1 in the first to 76.3 ± 6.3 Mg ha−1 in the fifth decade, at 0.45 ± 0.07 Mg ha−1 per year. Sugar yield increased 93% from the first (4.6 ± Mg ha−1) to the fifth (8.9 ± 0.76 Mg ha−1) decade at 0.1 ± 0.01 Mg ha−1 per year. The gains were neither significant nor consistent when comparing successive decades, incremental rather than rapid, and maintained once achieved. Significant (p < 0.05) gains in all traits occurred only in the third decade (1990–1999) with yearly increases of 1.15 ± 0.30 g kg−1 for sucrose content, 3.00 ± 0.27 Mg ha −1 for cane yield, and 0.35 ± 0.05 Mg ha−1 for sugar yield. Comparisons of trait means between successive decades found both significant (p < 0.05) and nonsignificant (p > 0.05) differences; however, comparisons between noncontiguous decades were all significant (p < 0.05). Variety development accounted for 60% of the progress with sucrose content contributing more (10% more) compared with cane yield. The Louisiana sugar industry has experienced substantial productivity gains in the last five decades thanks to a combination of factors with variety development being the most impactful.
Do sustainability practices contribute to the financial performance of banks? An analysis of banks in Southeast Asia
Authors: Gutiérrez‐Ponce Herenia , Wibowo Sigit Arie 
Published: October 2023

AbstractIn response to the need to deepen research on the impact of corporate ESG (environmental, social, and governance) pillars on the financial performance (FP) of banks, this study analyzes the relationship between ESG and FP in banks from emerging countries in Southeast Asia during the period 2010–2020. Using a sample of 19 banks from five countries with emerging economies, this article examines the level of information on ESG activities that banks report in each of their pillars and these pillars' impact on the FP. The research was conducted through an exploratory study using panel data (Thomson Reuters ESG data), parametric correlations, and regression models. FP is measured by return on assets (ROA), return on equity (ROE), and Tobin's Q (TQ), or the prevailing market price for exchanging assets divided by the market price of the goods newly produced. The findings show that ESG has a significant negative effect on all measures of FP (ROA, ROE, and TQ). However, analysis of the relationship of each individual ESG pillar to FP obtains different findings for each. Our study also shows differences in the level of ESG information in each country as a result of their specific economic characteristics. This study has limitations due to the limited ESG, bank, and country data that Thomson Reuters contains on banks in this region of Asia. In future research, more banks and more countries can be added to the analysis, as well as other control variables related to FP.

AbstractDue to the intrinsic safety and cost effectiveness, aqueous Zn‐ion batteries (AZIBs) are considered a promising candidate for future energy storage systems. However, the widespread implementation of AZIBs faces significant obstacles due to various undesirable side reactions, including hydrogen evolution reaction (HER), corrosion, and uncontrolled dendrite growth at the anodes. Here, 4‐hydroxybenzoic acid sodium salt (PHB) is employed in the ZnSO4 electrolyte to enable highly‐reversible zinc anodes. PHB has a greater tendency to bind with the Zn surface, resulting in increased steric effects within the electrolyte. As a result, it hinders the direct interaction between anode and water while facilitating the uniform plating of Zn2+. Zn/Zn batteries with PHB additives realized more than 1600 h stable cycling life under 1 mA cm−2 and 1 mAh cm−2. Moreover, Zn/Cu batteries with PHB additives achieved a reversible plating/stripping process for over 500 cycles with high average CE of 98.6 %. In addition, the assembled Zn/NH4V4O10 batteries with PHB additive yielded 80.5 mAh g−1 after 1000 cycles at 10 A g−1. The inexpensive and effective application of PHB as an electrolyte additive has the potential to significantly enhance the stability and dependability of ZIBs.

Published: October 2023

SummaryThe large integration of distributed generation (DG) and electric vehicles (EVs) facilitates daily life and reduces carbon emissions. However, it brings problems such as increased uncertainty and power electronic permeability to the distribution network. In this context, it is important to solve the line loss optimization problem as closely as possible to the real situation. Therefore, this paper solves the line loss optimization problem based on a probabilistic model of three‐phase unbalanced modern power electrical distribution network. Firstly, the paper proposes a frequency domain model of the distribution network and the optimization problem model. Then, to deal with the uncertainty of the system, the point estimation method (PEM) and Monte Carlo Simulation (MCS) are used. Finally, this paper proposes two optimization schemes considering the power quality when single and multiple DGs are integrated. The simulation results demonstrate that the PEM using the Gram–Charlier series expansion of the fourth‐order statistical moments to estimate the probability density function (PDF) is significantly less time consuming than the traditional MCS method while maintaining accuracy. The comparative analysis reveals that under the optimization scheme with single DG integration, the expected value of system line loss and expected line loss rate are reduced from 283.95 kW to 218.96 kW (22.89% reduction) and from 13.44% to 10.68%, respectively. Under the dual DG integrated optimization scheme, the expected value of line losses and expected line loss rate are reduced from 283.95 kW to 208.88 kW (26.4% reduction) and from 13.44% to 10.25%, respectively. However, after taking the uncertainty into account, the operational reliability of the system has been enhanced under different scenarios. In addition, it is found that the optimization approach incorporating multiple DG units can effectively mitigate the system line loss under diverse operational scenarios while enhancing the system's DG integration capability.

Published: October 2023

SummaryTwo fundamental aspects of wireless communication, which make it challenging and interesting, are fading and interference. Multiple input multiple output (MIMO) and orthogonal frequency division multiplexing (OFDM) techniques when utilized together effectively combat fading and interference thereby achieving the requirement of high data rate and high performance. In this paper, a 2 × 1 MIMO‐OFDM baseband model of the physical layer according to IEEE 802.16.1 standard employing 256 subcarriers capable of transmitting 192 Mbps in a 21‐MHz bandwidth frequency selective fading channel is designed. All essential blocks of the communication system like channel coding, modulation, time synchronization, frequency synchronization, channel estimation, residual carrier frequency offset (CFO) estimation, and channel decoding are covered at the algorithm level. A two‐step time synchronization method is used in this work to avoid any ambiguity in frame detection. A long preamble, consisting of three short preambles, is designed to aid in time synchronization, frequency synchronization, and channel estimation. To evaluate the performance of the proposed design, simulations were carried out in MATLAB‐SIMULINK.
Is African non‐annual killifish Fundulopanchax gardneri (Teleostei; Cyprinodontiformes; Nothobranchiidae) true non‐annual?
Authors: Borisov Vasily , Shkil Fedor , Seleznev Dmitry , Smirnov Sergei 
Published: October 2023

AbstractBackgroundAnnual or seasonal killifishes (Cyprinodontiformes: Nothobranchiidae) are unique among fish in their ability to enter into developmental arrests (diapauses: DI, DII, and DIII). They have a short lifespan and their embryos are exceptionally tolerant to a variety of environmental stresses. These traits make them a popular model for studying vertebrate diapause, aging, stress tolerance, genome adaptation, and evolution. In such issues, in a comparative evolutionary framework, Fundulopanchax gardneri, a popular aquarium fish from Africa, is commonly used as a representative non‐annual model though its development is not studied in detail and whether it includes diapauses remains uncertain.ResultsWe described in detail for the first time embryonic development of F. gardneri and revealed it to resemble that in the undoubtedly annual Austrofundulus limnaeus killifish in displaying two developmental depressions. However, if compared with A. limnaeus, these developmental states look like “less intense” versions of DII and DIII rather than true diapauses.ConclusionsTo determine whether developmental depressions in F. gardneri represent “true” diapauses or only their functional equivalents, detailed studies of embryonic development of different killifish both annual and non‐annual are needed. Before that, acceptance of F. gardneri as a representative non‐annual fish seems premature.

AbstractObjectiveAn extensive number of predictors has been examined across the literature to improve knowledge of relapse in anorexia nervosa (AN). These studies provide various recovery and relapse definitions, follow‐up durations and relapse rates. The current study summarizes these values and predictors of relapse in AN in a review and meta‐analysis.MethodThe study was executed according to PRISMA guidelines. Different databases were searched and studies in which participants did not receive an official clinical diagnosis were excluded. A quality analysis was performed using the National Institute of Health's Study Quality Assessment Tool. Random‐effects meta‐analyses were conducted to summarize data.ResultsDefinitions of relapse and recovery were diverse. During an average follow‐up period of 31 months an average relapse rate of 37% was found. Predictive variables from 28 studies were grouped in six categories: age and sex, symptoms and behaviors, AN subtype and duration, weight or weight change, comorbidity, and personality. The studies were characterized by non‐significant and contradictory results. Meta‐analyses were performed for the predictors age, AN duration, pre‐treatment BMI, post‐treatment BMI and depression. These yielded significant effects for post‐treatment BMI and depression: higher pre‐treatment depression (SMD = .40 CI [.21–.59] and lower post‐treatment BMI (SMD = −.35 CI [−.63 to −.07]) increased relapse chances in AN.DiscussionOur results emphasized a lack of sufficiently powered studies, consistent results, and robust findings. Solely post‐treatment BMI and pre‐treatment depression predicted relapse. Future research should use uniform definitions, larger samples and better designs, to improve our understanding of relapse in AN.Public significanceKnowledge about predictors is important to understand high relapse rates. Our study performed a review and meta‐analysis of relapse predictors in AN. Related to the heterogeneity in studies examining predictors, an overview of relapse and recovery definitions, follow‐up durations and relapse rates for AN was provided. Significant effects were found for post‐treatment BMI and pre‐treatment depression. More studies with uniform definitions are needed to improve clinical implications.

Published: October 2023

AbstractWe herein report a protocol for the α‐thio‐ and α‐seleno‐cyanation of different cyclic β‐ketoesters and oxindoles by using NaSCN or KSeCN as easily accessible inorganic nucleophilic S(e)CN sources under oxidative conditions. Key to success for both transformations is the use of dibenzoylperoxide as an oxidant allowing for the coupling of two inherently nucleophilic species under operationally simple conditions in high yields and with broad functional group tolerance.
Probing the Impact of Added Al(OTf)3 on DalPhos/Nickel‐Catalyzed N‐Arylations of Amides with (Hetero)aryl Chlorides

Published: October 2023

AbstractWe disclose herein our study examining the potential activating effect of added aluminum triflate (5 mol %) on the (DalPhos)Ni(aryl)Cl (1 mol % Ni) catalyzed C−N cross‐coupling of primary amides with (hetero)aryl chlorides. In some instances, dramatically improved conversion to product was achieved by use of added aluminum triflate; with furfurylamine catalytic inhibition occurred. The reaction outcome appears to result from the interplay of DalPhos ligand and aryl group within the Ni pre‐catalyst, as well as the identity of the cross‐coupling partners.
Evaluation of the energy consumption of hybrid desalination RO‐MED‐FD to reduce rejected brine
Authors: Salajeghe Maryam , Ameri Mehran 
Published: October 2023

AbstractThe escalating global capacity of desalination plants has posed a significant environmental threat due to the discharge of brine. Consequently, urgent treatment of these hypersaline brines has become imperative. This article provides an overview of a novel hybrid model for water desalination. Energy consumption and brine discharge of three desalination configurations, namely freeze desalination (FD), multi‐effect desalination (MED), and reverse osmosis (RO), are compared. The configurations encompass FD, MED‐FD, and RO‐MED‐FD, with FD utilizing the brine from MED and RO desalination. The hybrid desalination system integrates with combined power and cooling CO2 system (CPCS‐CO2) for energy supply. This hybridization offers enhanced operational flexibility, increased desalination capacity, and reduced brine discharge. Optimal gas heater pressure exists for different temperatures and salt concentrations in saline water. The findings demonstrate a noteworthy 47% and 50% reduction in energy consumption and brine discharge, respectively, in RO‐MED‐FD compared to simple FD.
Implicit coupling methods for nonlinear interactions between a large‐deformable hyperelastic solid and a viscous acoustic fluid of infinite extent
Authors: Li Yapeng , Qu Yegao , Meng Guang 
Published: October 2023

AbstractThis paper addresses the challenges in studying the interaction between high‐intensity sound waves and large‐deformable hyperelastic solids, which are characterized by nonlinearities of the hyperelastic material, the finite‐amplitude acoustic wave, and the large‐deformable fluid–solid interface. An implicit coupling method is proposed for predicting nonlinear structural‐acoustic responses of the large‐deformable hyperelastic solid submerged in a compressible viscous fluid of infinite extent. An arbitrary Lagrangian–Eulerian (ALE) formulation based on an unsplit complex‐frequency‐shifted perfectly matched layer method is developed for long‐time simulation of the nonlinear acoustic wave propagation without exhibiting long‐time instabilities. The solid and acoustic fluid domains are discretized using the finite element method, and two different options of staggered implicit coupling procedures for nonlinear structural‐acoustic interactions are developed. Theoretical formulations for stability analysis of the implicit methods are provided. The accuracy, robustness, and convergence properties of the proposed methods are evaluated by a benchmark problem, that is, a hyperelastic rod interacting with finite‐amplitude acoustic waves. The numerical results substantiate that the present methods are able to provide long‐time steady‐state solutions for a nonlinear coupled hyperelastic solid and viscous acoustic fluid system without numerical constraints of small time step sizes and long‐time instabilities. The methods are applied to investigate nonlinear dynamic behaviors of coupled hyperelastic elliptical ring and acoustic fluid systems. Physical insights into 2:1 and 4:2:1 internal resonances of the hyperelastic elliptical ring and period‐doubling bifurcations of the structural and acoustic responses of the system are provided.
Elucidation of the effects of autochthonous starter on nitrogen‐containing compounds during fermentation of Yujiangsuan by metabolomics

Published: October 2023

AbstractTo understand the role of microorganisms in nitrogen (N)‐containing compound changes during the processing of Yujiangsuan by autochthonous starter cultures, the GC‐TOF‐MS‐based metabolomics method was adopted to investigate the effects of Weissella cibaria and Lactobacillus plantarum. The results demonstrated that inoculation of autochthonous strains led to differential metabolites, such as fatty acids, organic oxygen compounds, and carboxylic acids on day 4 to day 12 of fermentation. The N‐containing compounds under the inoculated fermentation group showed a faster relative concentration change. Nucleotide metabolism and arginine and proline metabolism exerted an influence on the formation of N‐containing compounds. Apart from that, the effect of W. cibaria and L. plantarum on the hydrolysis of macromolecules was the main factor causing differences in major N‐containing compounds.

AbstractObjectiveTo establish an acute canine coronary artery occlusion model by implanting a mixed thrombus prepared in vitro into the coronary artery by percutaneous coronary intervention (PCI).MethodsThis study included 14 healthy Beagle dogs aged 10–13 months. First, 5 ml of canine venous blood was drawn to prepare the coronary artery thrombus in vitro. The thrombus was then implanted into the canine coronary artery by PCI to establish an animal model of acute coronary artery occlusion. Dogs were randomly divided into two experimental groups: group A, in which dogs were assessed for 2 h after coronary occlusion, and group B, in which dogs were assessed for 4 h after surgery. Baseline and postoperative assessment included cardiac troponin T (cTnT) levels, electrocardiography (ECG), plain and contrast echocardiography, and large‐scale digital subtraction angiography (DSA).ResultsCanine venous blood was successfully used to prepare a mixed thrombus with reticular fibrin structure and activated platelets in vitro. After the mixed thrombus was implanted into the coronary artery, large‐scale DSA showed no contrast medium perfusion, confirming complete occlusion of the coronary artery. After the coronary artery occlusion, dogs in both groups showed ST segment elevation >0.5 MV, a 0.9 μg/L increase in CTnT (p < 0.001), and increased EDV and ESV. Dogs also showed decreased left ventricular EF and FS and decreased MBF in the infarcted area (p < 0.05).ConclusionsAn experimental model of acute coronary artery occlusion in dogs was successfully established by implanting a mixed thrombus developed in vitro into the coronary artery using minimally invasive PCI.
