AbstractAlopecia areata (AA) is a complex genetic disease that results in hair loss due to an autoimmune‐mediated attack on the hair follicle. Mesenchymal stem cells (MSCs) have great potential to induce hair regeneration due to their strong secretion ability and multidirectional differentiation. Recent studies have revealed that the therapeutic potential of MSCs comes from their secretion ability, which can produce large amounts of bioactive substances and regulate the key physiological functions of subjects. The secretion products of MSCs, such as vesicles, exosomes, and conditioned media, have significant advantages in preparing of biological products derived from stem cells. Human umbilical cord mesenchymal stem cells (uMSCs) are the best choice for exosome production. uMSCs are obtained from the human umbilical cord. The umbilical cord is easy to obtain, and the efficiency of uMSCs isolation and culture higher than that of obtaining MSCs from bone marrow or adipose tissue. In this study, we investigated the effects of exosomes released from uMSCs in AA mice. In summary, due to easy isolation and cultivation, simple preparation, and convenient storage, it is possible to obtain uMSCs, or uMSCs exosomes for research and clinical treatment.

AbstractBackgroundBreast cancer (BC) is the most common cancer among women worldwide. Increased survival of primary BC (PBC) has increased contralateral breast cancer (CBC) and become a health problem.AimsThis study aimed to determine the effect of disease‐free interval (DFI), risk factors and PBC characteristics on the progression of CBC within primary BC survivors.Methods and ResultsThis retrospective study identified 5003 women diagnosed with breast cancer between 2000 and 2020 in the cancer research center. The study included 145 CBC and 4858 PBC survivors, with CBC diagnosed at least 6 months after the detection of primary BC. ER+, PR+, and HER2+ were reported in 72.13%, 66.67%, and 30% of CBC patients. Invasive ductal carcinoma (IDC) BC was reported in 69.57% of patients, and 81.90% and 83.64% of the patients were treated with adjuvant chemotherapy and external radiotherapy. The Kaplan–Meier method indicated that the median time interval between PBC and CBC was 3.92 years, and the 5‐year DFI was 97%. The Cox proportional hazard regression model indicated that although more than half of the participants had no family history of BC (69.57%), women 60 years and older were negatively associated with CBC.ConclusionThis study provides the first investigation of CBC and DFI risk factors among PBC survivors in Iran. Age was found to be negatively associated with CBC development particularly after the age of 60, indicating the necessity of tracking CBC survivors carefully in this age group.

Published: November 2023

AbstractA method for the voltammetric determination of tin using a multiwall carbon nanotubes/spherical glassy carbon (CNTs/SGC) electrode is described. The new procedure is based on the adsorptive accumulation of the Sn(II)‐cupferron complex on a CNTs/SGC electrode modified with a lead film, followed by electrochemical reduction of the adsorbed species. The optimal experimental conditions include the use of 0.10 mol L−1 acetate buffer (pH 5.7), 4.0×10−4 M cupferron and 1.0×10−4 M Pb(II). The peak current is proportional to the concentration of Sn(II) over the range of 1.0×10−9–1.0×10−7 M and the detection limit is 3.1×10−10 M for a 95 s accumulation time. The proposed method was used to determine tin in real samples and certified reference materials.
Vitamin A: It's role in cosmeceuticals for antiaging
Authors: Farris Patricia K. 
Published: November 2023

AbstractTopical retinoids are among the most well‐studied and widely used cosmeceutical ingredients. Topical retinoids have skin rejuvenating benefits and can soften fine lines and wrinkles, lighten mottled hyperpigmentation, improve skin roughness, sallowness, and overall appearance of photoaged skin. Retinoic acid or tretinoin remains favored among dermatologists because there are a plethora of well‐designed clinical trials confirming its efficacy as a topical therapy for treating aging skin. In contrast, cosmeceutical retinoids are regulated as cosmetics and in general are not subjected to the same degree of scientific rigor as prescription retinoids. Despite this difference, there are studies confirming the antiaging benefits of cosmeceutical retinoids and studies comparing their efficacy and tolerability to tretinoin. This review will focus on over‐the‐counter retinoids including retinol, retinaldehyde, retinyl esters, adapalene, and novel retinoid molecules. Studies on pharmacokinetics, mechanisms of action, clinical benefits, and tolerability will be reviewed.

Published: November 2023

AbstractWith the successful implementation of Software‐Defined Networking (SDN) in data center networking, the way forward for its deployment in the ISP/Telco network is becoming prominent. Small and medium‐sized networks may easily adopt SDN. The research on SDN deployment and implementation for a large‐scale network is continuing. This paper properly presents the current research status of Controller Placement Problem (CPP) and Multi‐CPP (MCPP) over SDN with their specific challenges and provides a comprehensive review of the major performance metrics, that is, latency, and controller load balancing techniques. This survey highlights the use of network partitioning‐based CPP and clustering approaches and their benefits in the context of SDN deployment. Moreover, this paper highlights the importance of implementing SDN and SDN security issues into ISP/Telco networks. Finally, we provide some key areas of ongoing research and discuss the future research direction regarding the various SDN‐based Controller Placement (CP) issues in the next‐generation IP and advanced networking technologies.

Published: November 2023

AbstractSubway stations are important components of subway system planning and urban rail transit where passengers can board, alight, transfer, or wait. With an increase in urban passenger flow, subway stations must meet greater transfer‐space demands commensurate with growing station structure sizes. In this study, the field‐monitoring and analysis method was adopted to investigate the Huaxing Street Station of the Chengdu Metro Line 19 project and explore the temperature‐variation rule in the process of mass‐concrete pouring in the station floor. Based on an ABAQUS large‐finite‐element calculation programme and secondary development of damage and failure research methods, a mechanical model of mass‐concrete pouring in subway‐station floor construction was established. The pouring temperature effect, damage, and failure mechanism of mass‐concrete pouring in subway stations were comprehensively studied. The main results were as follows: (1) the maximum temperature difference between the upper and middle layers of the floor was dominant and reached a peak within 1–3 d after the completion of pouring, and the temperature difference gradually decreased with a decrease in the hydration‐heat reaction. (2) At 0–10 d, the damage ratio of the floor increased by 1.8%, predominantly in the form of longitudinal damage. Within 10–30 d, the damage and failure ratio of the floor increased by 1.86%, primarily in the form of transverse damage and failure. Within 30–40 d, the temperature of the floor stabilized and gradually approached the ambient temperature. The damage and failure ratio of the floor increased by 0.32% at this time. (3) The lower the ambient temperature, the greater was the damage sustained by the floor at different ages, and the ambient temperature had a significant influence on floor damage.

Published: November 2023

AbstractShort carbon fiber‐reinforced polymer composites are desirable for many additive manufacturing (AM) applications as they are light and structurally strong. The process parameters in fused filament fabrication (FFF) significantly affect the mechanical properties of SFRP parts. In this work, three‐point bending tests are carried out to investigate the flexural behavior of 3D‐printed polyamide 12 carbon fiber (PA12‐CF) specimens. An L18 Taguchi design of experiments with Gray relational analysis is applied to optimize the FFF parameters. It is shown that build orientation has the most influence on flexural properties and the distribution of short fibers has an additional effect. For a rectilinear infill pattern, the maximum flexural strength of the part was realized at the printing speed, layer thickness, and extrusion temperature of 30 mm/s, 0.15 mm, and 270°C, respectively. With these parameters, the flexural strength of the part is 119.9 MPa and the flexural modulus is 3038 MPa. For a concentric infill pattern, the flexural strength of the part is 15.8% higher at 138.8 MPa. The flexural modulus is also higher at 3692 MPa. This study's results contribute toward optimizing FFF parameters to suit the specific flexural loading requirements of an AM part.

Abstract
Salinity has been reported to impact the octanol–water partition coefficient of organic contaminants entering aquatic ecosystems. However, limited data are available on the impacts of salinity on their partitioning from the aqueous phase to adjacent organic compartments. The pesticides bifenthrin, chlorpyrifos, dicloran, myclobutanil, penconazole, and triadimefon were used to investigate the effects of salinity on their partitioning to capelin (Mallotus villosus) eggs in 5 practical salinity units (PSU) versus 25 PSU artificial seawater (ASW). The partitioning coefficient was significantly higher in 25 versus 5 PSU ASW for bifenthrin, chlorpyrifos, dicloran, penconazole, and triadimefon by 31%, 28%, 35%, 28%, and 20%, respectively, while for myclobutanil there was no significant difference. Moreover, pesticide partitioning to store-bought capelin eggs was consistent with the partitioning observed for the standard assay species, inland silversides (Menidia beryllina) eggs, after partitioning between the eggs and exposure solution had reached a state of equilibrium. The present study illustrates the importance of considering the influence of salinity on the environmental partitioning and fate of hydrophobic organic contaminants in aquatic ecosystems.

Authors: Sabarre Nina R. , Beckmann Blake , Bhaskara Sahiti , Doll Kathleen 
Published: November 2023

AbstractWhile many knowledge workers may fear that the rise of artificial intelligence (AI) will threaten their jobs, this article argues that small evaluation businesses should embrace AI tools to increase their value in the marketplace and remain relevant. In this article, consultants from a research, evaluation, and strategy firm, Intention 2 Impact, Inc., make a case for using AI tools to disrupt business as usual in evaluation from theoretical and practical perspectives. Theoretically, AI may be another example of technology that was initially feared but is now ubiquitous in society. Using concrete examples, the authors describe how businesses and evaluators have evolved to keep up with changes in supply and demand. Lastly, it is posited that embracing AI will save time for those working in small businesses, which can ultimately increase added value and profitability.

Published: November 2023

AbstractIn the present study, a novel combined power cycle for solar power tower (SPT) system consisting of helium Brayton cycle (HBC) and transcritical CO2 (TCO2) for waste heat recovery is being studied for carbon‐free generation. The performance of the proposed SPT based combined cycle (SPT‐HBC‐TCO2 cycle) is compared with SPT based basic cycle (SPT‐HBC) based on exergoeconomic and thermodynamic analyses. It is concluded that the SPT‐based combined cycle (SPT‐HBC‐TCO2 cycle) produces a thermal efficiency of 32.39% and exergy efficiency of 34.68% with an electricity cost of 1.613 UScent kWh−1. The exergy and thermal efficiency of the SPT‐based combined cycle are enhanced by 13.18% and 13.21% respectively, while electricity cost is reduced by around 2% as compared to the SPT‐based basic cycle (SPT‐HBC) configuration at base conditions. A notable finding is that, despite the additional expenditures related to the bottoming cycle, the cost of electricity is lesser for the proposed combined cycle. Additionally, a comparison with the related prior published research exhibits that the performance of the current novel system is superior to that of the systems based on steam rankine cycle and supercritical CO2 cycles.
Attracting institutional investments to emerging markets: The case of Turkiye
Authors: Avci S. Burcu 
Published: November 2023

AbstractUnderstanding institutional investors' investment criteria in emerging markets is essential because they typically make large investments without control rights or protection of the rule of law. This study undertakes an investment criteria investigation of institutional investors in Turkiye. The sample covers real and financial sector companies to investigate sectoral differences in Borsa Istanbul‐listed firms for 2010–2021. Using a panel data approach, we show that the presence of growth options, generous payout policy, attractive firm valuation, and quality of the external governance mechanisms are important factors in attracting institutional investors by real sector firms. Only a large firm size and the quality of the external governance mechanisms arise as important factors for financial sector firms. Moreover, institutional holdings positively impact the percentage shares of institutional investors during crisis periods among real sector firms, whereas they do not affect financial sector firms. Real‐sector and financial‐sector firms can use our findings to increase institutional ownership. Our results have important implications for institutional investors, individual investors, and market regulators to demand critical corporate governance practices.

AbstractObjectiveTo assess menstrual hygiene management (MHM) and period poverty in a group of low‐ and medium‐income menstruating people.MethodsA cross‐sectional study was conducted at the University of Campinas, Brazil, from January to June 2022 with 535 participants aged 18–49. For data collection, we used the abbreviated version of the WHO Quality‐of‐Life questionnaire (WHOQOL‐BREF) and a pre‐tested questionnaire with items regarding MHM and period poverty.ResultsWe found an inverse relationship between the risk of no access to supplies to perform menstrual hygiene, which increased by 2.5% and each point less in the environmental domain of quality of life (QoL), and this risk increased by up to 3.1 times among participants who reported difficulty making ends meet. The risk of not having adequate conditions to perform menstrual hygiene at home increased by up to 2.6% for every one‐point drop in the environmental domain of QoL. The risk of not having adequate conditions to perform menstrual hygiene outside the home increased by up to 1.3% for less points in the psychological domain of QoL, and 44.4% of those who indicated inadequate conditions for menstrual hygiene reported two or more childbirths.ConclusionsMenstruating people who have an increased risk of lacking menstrual supplies and have an increased risk of inadequate conditions for MHM at home and outside the home, as well as those who have two or more deliveries and those having difficulties making ends meet, scored low on the QoL, especially in the environmental and psychological dimensions.

Published: November 2023

AbstractThis study aims to develop a proficient and clinically applicable algorithm that can accurately assess bone age. This algorithm is based on the principles of the Tanner‐Whitehouse 3 (TW3) integral approach, and aims to achieve efficiency, scalability, and interpretability. We developed a model for bone age prediction in children. The model was tested on a pediatric dataset from a tertiary care hospital consisting of left‐hand radiographs of children between the age of 0 and 18. Our model consists of removing the arm portion using a pre‐trained YOLO network, localizing 37 key points in the hand bone portion using a spatial configuration network, and segmenting the original image through 20 of these points to obtain 20 fixed‐size patches. Finally, each of the 20 bone images is classified by training a visual transformer (ViT) model. In this study, a hybrid network, SVTNet, was developed that incorporates visual transformers to obtain estimates of bone age in the carpal (C series) and metacarpal (RUS series) bones. The sum of the clinical TW3 scoring region scores and bone maturity scores were utilized to determine the bone age for each corresponding region. The performance of the algorithm was evaluated in terms of both training and testing by evaluating 3871 left hand X‐ray micrographs obtained from a tertiary hospital in China. The results showed that the average absolute error of bone age estimation was 0.50 years for the RUS series of bones and 0.47 years for the C series of bones. The main contribution of this study is to propose, for the first time, a ViT‐based bone age assessment method that automates the entire process of the TW3 algorithm and is clinically interpretable, with predictive accuracy comparable to that of an experienced orthopedic surgeon.

Published: November 2023

AbstractAntibody assays with the nucleocapsid (NC) protein as the target antigen can identify severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) infections when polymerase chain reaction (PCR) analyses are unavailable. Regarding the kinetics of NC‐specific antibodies, vaccine breakthroughs with Omicron subvariants may differ from infections with the ancestral wild‐type virus. Therefore, we evaluated which assays have the highest sensitivity for detecting NC‐specific antibodies after various intervals since breakthrough infections with an Omicron subvariant. The study included 279 samples from vaccinated subjects who experienced PCR‐confirmed Omicron breakthrough infections between 21 and 266 days before sampling. The samples were comparatively assessed with the Elecsys® Anti‐SARS‐CoV‐2 N (Roche), the Anti‐SARS‐CoV‐2‐NCP‐ELISA (Euroimmun), the recomLine SARS‐CoV‐2 IgG (Mikrogen), and the SARS‐CoV‐2 ViraChip IgG assays (Viramed). In the whole cohort, the Elecsys® Anti‐SARS‐CoV‐2 N assay displayed the highest sensitivity (93%, p < 0.0001), followed by the recomLine SARS‐CoV‐2 IgG assay (70%), the SARS‐CoV‐2 ViraChip IgG assay (41%) and the Anti‐SARS‐CoV‐2‐NCP‐ELISA (35%). Although measured antibody levels and time‐dependent sensitivities differed, the extent of the antibody decrease was similar among all assays. As demonstrated by this study, manufacturer‐dependent differences in the sensitivities of NC‐specific antibody assays should be considered when serology is applied to link previous SARS‐CoV‐2 infections with potential post‐COVID sequelae.
