Published: May 2024

Abstract
With the increasing use of medical equipment, threads are the catchy choice for medical personnel to solve wound closures. One raw material used in medical surgical threads is polylactic acid (PLA), which is appropriate for its environmentally friendly and biodegradable properties. However, the weakness of PLA is in mechanical properties. This work used extrusion-based three-dimensional (3D) printing (fused deposition modeling) to fabricate medical threads from PLA. The effect of adding seed husk waste powders (SHWPs) to PLA filament (1.75 mm) and its manufacture by the 3D printer was studied. Four types of SHWP waste plants were used: pistachio, coffee, chestnuts, and walnuts crushed and milled by ball-milling after chemical processing and drying. The structural, particle size, and physical properties of the prepared powders were studied. The results of SHWPs show that the particle size is near the nano-size range of NPs and of low density. Different SHWP weight mixing ratios (5–15 wt%) were coated to PLA threads (0.4–0.45 µm) by grafting to study the mechanical (surface hardness and roughness) properties. The result shows that 15 wt% was the best ratio that combined the mechanical properties. The coated layer thickness was less than 5 µm. This ratio was adopted to fabricate grafted PLA and SHWPs/PLA medical threads by 3D printing with a radius of 400 ± 5 µm. The structural and biological properties of the fabricated medical threads were investigated. The results of SHWP-coated PLA show a significant improvement in structural and physical properties besides the mechanical properties. The results adopted this percentage from thread SHWP-coated PLA for medical applications, creating a new benefit for agricultural SHW and accelerated healing.
Cellulosic materials for the removal of ciprofloxacin from aqueous environments
Authors: Chikowe Ibrahim , Bala Muhammad Dabai 
Published: May 2024

Abstract
The feasibility of using cellulose from Pinus spp. sawdust from Zomba, Malawi, treated with commercial and lemon-derived citric acid (CA) for ciprofloxacin (CFX) adsorption from water has been tested. Different CA concentrations were used on NaOH-pretreated sawdust for cellulose esterification. The material was analysed using a variety of techniques. Adsorption tests for CFX were performed using the batch method, and the data were analysed using Langmuir, Freundlich, and Temkin’s isotherms. The Fourier transform infrared spectroscopy (FTIR) and point of zero charge results showed surface charges increasing (hydroxyl, −OH, and carboxyl, −COOH groups) due to the CA reaction. The Temkin model was the best fit for the experimental data with R
2 test values of 0.9515, while pseudo-second-order was the best fit (R
2 = 0.9999) in an exothermic adsorption process. The adsorption efficiency was 83% on 0.8 g of the material at pH 4 in 20 mL (20 mg·L−1) CFX. The different CA concentrations during sawdust treatment had a negligible impact on morphology. A regression analysis (R
2 and p-values) of structural data showed that the particle size, distance, and crystallinity index had negligible impact, while surface charges and functional groups had a significant impact on adsorption. Overall, the adsorption of CA-treated sawdust material on CFX is satisfactory.
Augmented total theatre: shaping the future of immersive augmented reality representations
Authors: Cicconi Sergio 
Published: May 2024

Abstract
This work introduces Augmented Total Theatre (ATT), a new theatrical form that combines Total Theatre with Augmented Reality (AR) to transform theatrical experiences. We first explore ATT features, highlighting its capabilities in creating theatrical representations that surpass traditional theatre. We also examine current technological limitations that hinder the deployment of ATT potential. We venture then into a journey into the future, particularly focusing on the next decade. We try to envisage the evolution of AR and assess whether future advancements will yield a form of AR capable of creating digital worlds that can deceive human senses. Additionally, we explore the role of Generative AI systems in addressing the problems that hold back the current ATT. Specifically, we probe the feasibility of a cost-effective, autonomous, and highly efficient generative AI system to reshape and empower ATT, making it capable of real-time production of (theatrical and non-theatrical) representations of many events in the world. Finally, we try to imagine the ATT of the future: a sophisticated device that integrates cutting-edge AR technology with a super-performing generative AI system. This ATT, transcending its theatrical origins, emerges as a powerful tool for augmenting our sensory experiences and enriching our perception of reality.
Collusion and Price Behavior in the U.S. Pork Industry
Authors: Bolotova Yuliya V. 
Published: May 2024

Abstract
This research analyzes the U.S. pork industry dynamics in light of the alleged output price-fixing cartel of the largest pork processors revealed in the antitrust lawsuits filed by pork buyers beginning in 2018. The empirical evidence may suggest that pork production, the farm, wholesale, and retail values of pork, and marketing margins increased, but the farm sector share decreased in the cartel period (2009–2019), as compared with the pre-cartel period (1998–2008). The wholesale pork pricing by pork processors is consistent with oligopoly pricing in both the pre-cartel and cartel periods. While the estimated decrease in cost pass-through between these two periods may reflect an increase in the seller (oligopoly) market power of pork processors in the cartel period, this cost pass-through decrease is not statistically significant from zero. The retail pork pricing by food retailers is consistent with perfectly competitive pricing in both the pre-cartel and cartel periods.
Harpy eagle kill sample provides insights into the mandibular ontogenetic patterns of two-toed sloths (Xenarthra: Choloepus)
Authors: Pasin Lucas C. , Casali Daniel M. , Semedo Thiago B. F. , Garbino Guilherme S. T. 
Published: May 2024

Abstract
Skeletal ontogeny of xenarthrans is poorly known, especially because of the paucity of study specimens from distinct developmental stages. Here, we investigate morphometric aspects of the mandible ontogeny in the two-toed sloths, Choloepus spp. We examined mandibles of infant, juveniles and subadult sloths that were present in kill assemblages of harpy eagles, Harpia harpyja, and complemented our study with adult museum specimens. We carried out uni- and multivariate linear morphometric analyzes to assess the growth pattern of the mandible. Harpy eagles did not prey on adult two-toed sloths, preferring younger individuals. We found an overall strong correlation between the total length of the mandible and other mandibular measurements across age classes, with some of them scaling isometrically, and others presenting allometric growth. Also, morphometric data correlated with patterns of symphysial fusion across ontogenetic stages, rendering the latter a reliable indicator of the animal’s age category. Although it was necessary to complement our sample with museum material, individuals obtained from the harpy eagle kill assemblage proved to be a valuable complementary source of specimens to be studied.

Published: May 2024

Abstract
Miniature spectrometer is powerful tool for scientific research and industrial inspection. Here, we report the fabrication of graded perovskite filters with tunable bandgap and their application in constructing miniature spectrometer. The graded perovskite filters were fabricated using a Finkelstein reaction between in-situ formed halogen ion with a preformed MAPbX3 film. The graded bandgap of perovskite films can be well tunned from 400 to 750 nm by controlling the volume ratio between 5,5-dimethyl-1-pyrroline N-oxide and benzyl chloride(bromide). By combining a deep residual network, graded bandgap perovskite film and commercial CMOS sensor chip, a miniature spectrometer is demonstrated, achieving an accurate spectrum reconstruction (PSNR = 40.749) with monochromatic spectral resolution of 1.31 nm.

Published: May 2024

Abstract
The demand for advanced camouflage technology is increasing in modern military warfare. Multispectral compatibility and adaptive capabilities are increasingly desired features in camouflage materials. However, due to the strong wavelength dependence and limited tunability of electromagnetic wave responses, achieving simultaneous multispectral compatibility and adaptive capability in a single structure or device remains a challenge. By integrating coding metamaterials with infrared (IR) electrochromic devices, we demonstrate a highly integrated multispectral metal-based electro-optical metadevice. The fabricated metadevices enable the reversible tunability of IR emissivity (0.58 at 3–5 µm, 0.50 at 7.5–13 µm) and wideband microwave scattering reduction (>10 dB at 10–20 GHz). The excellent integration performance is attributed to the remarkable electromagnetic control capabilities of the coding metamaterials in a chessboard-like configuration and the IR electrochromic devices based on metal reversible electrodeposition. Furthermore, the monolithic integrated design with shared barium fluoride substrate and electrodes allows the metadevices to have a simple architecture, and the careful design avoids coupling between functions. Our approach is general enough for the design of various electrochromic devices and metamaterials for multispectral camouflage, offering valuable insights for the development of advanced adaptive multispectral camouflage systems.
Primary renal synovial sarcomas diagnosed by a novel fusion gene with the fusion site involving exons of SS18 and SSX2: a case report
Authors: Qiu Hong , Tang Zhaorong , Nie Dan 
Published: May 2024

Abstract

Objectives
Primary renal synovial sarcoma (PRSS) is an uncommon malignancy with diagnostic challenges and poor prognosis. Research on PRSS is limited, primarily based on case reports, leading to a lack of widely recognized effective treatment options. This article reports a case of primary renal synovial sarcoma diagnosed using a novel fusion gene with a fusion site involving the SS18 and SSX2 exons.

Case presentation
A 34-year-old male, presented with intermittent right upper abdominal pain. Abdominal CT revealed an isolated mass in the upper pole of the right kidney, which was initially diagnosed as renal cell carcinoma. The patient underwent radical right nephrectomy, and postoperative histopathological examination confirmed the diagnosis of synovial sarcoma, and immunohistochemistry supported the diagnosis. Further detection through RT-PCR and DNA sequencing confirmed the presence of the SS18-SSX2 fusion gene. Despite the recommendation for adjuvant therapy, the patient refused chemotherapy and other treatments and succumbed to systemic metastasis.

Conclusions
This case highlights the diagnostic challenges and aggressive nature of PRSS. The novel fusion gene with the fusion sites SS18: exon9 and SSX2: exon5 has important implications for the diagnosis of primary synovial sarcoma of the kidney. Further research is warranted to explore novel therapeutic strategies and improve patient outcomes in PRSS.

Published: May 2024

Zusammenfassung
Die Verpflegung in deutschen Hochschulen, organisiert durch Studierendenwerke, spielt eine zentrale Rolle für Studierende und Mitarbeiter. Eine vollwertige Ernährung hat Potenzial für Prävention und Gesundheitsförderung. Die Bedeutung einer gesunden Ernährung wird von einer Mehrheit anerkannt, doch die Umsetzung im Alltag scheitert oft z.B. aufgrund sozialer Einflüsse. Nudging-Methoden und DGE-Qualitätsstandards in Mensen könnten die Inanspruchnahme der ausgewogenen Ernährung fördern.

Abstract

Objectives
Clinical biochemistry laboratories (CBL) are the most frequently utilized laboratory group in healthcare, and their significance in patient care is indisputable. This study investigated the frequency and pattern of test utilization rate in CBL at two large hospitals’ outpatient and inpatient clinics.

Methods
A total of 43,732,428 CBL tests, including clinical chemistry, immunoassay, coagulation, specific proteins, CBC, and urinalysis, were conducted for 12,182,382 patients across two large hospitals in different settings between 2018 and 2022. These tests were analyzed alongside patient admissions data, with a focus on the distribution across various clinics.

Results
A total of 94 % and 93 % of those admitted to Hospitals 1 and 2 were outpatients. They had applied to CBL laboratories for 27.1–30.3 % of outpatients and 81.2–88.7 % of inpatients for at least one test. When analyzing the rates at which laboratory tests were requested for outpatients, it was found that emergency departments had the highest test-requesting rates, ranging from 19.99 to 45.36 %. This was followed by internal medicine clinics, with rates ranging from 13.77 to 14.8 %, and inpatient intensive care units, with rates between 24.31 and 30.14 %. Outpatients had 10–11 test requests for each patient and 16–31 for inpatients. The most frequently requested laboratory tests were CBC, glucose, creatinine, urea, AST and ALT in two hospitals.

Conclusions
Despite significant variations in location, structure, medical staff, and patient demographics, approximately one-third of outpatients and 85 % of inpatients at these hospitals undergo testing in CBL. CBLs are essential for screening, diagnosis, prognosis, and healthcare treatment.
Files of the Polish Welfare Committee Kraków–Miasto as a source for studying women’s history in 1939–1945
Authors: Czocher Anna 
Published: May 2024

Files of the Polish Welfare Committee Kraków–Miasto (Polish name: Polski Komitet Opiekuńczy Kraków-Miasto, acronym PolKO) are stored in the National Archives in Kraków and have been open to research for years. These files are a highly valuable source for researching the reality of life under occupation, and one of the archival collection whose potential is not being fully exploited by researchers. The purpose of this review is therefore an attempt to show the potential that the PolKO files contribute to the study of women’s history and its interdisciplinary potential. The Polish Welfare Committee Kraków–Miasto was a local branch of the Central Welfare Council (Rada Główna Opiekuńcza, RGO) that remained the only Polish welfare organisation in the General Government whose operation was permitted by the Germans. The records produced by the committee, albeit incomplete, reflect the main courses of activities these institutions undertook. Why can they useful as a source for researching women’s history? During the German occupation, official charitable activities became the domain of women. They were the majority among PolKO Kraków–Miasto personnel and cooperating individuals. The wartime circumstances also made women a majority among the committee’s beneficiaries. Analysing the PolKO records, you find information concerning both individual women’s motivation for embarking on charitable activity, the nature of work they performed, and the degree of involvement on the one hand, and reasons for poverty, and the types of support expected and delivered on the other.

Authors: Arefi Hossein Namvar , Jarollahi Farnoush , Mohsen Samer Mohammad , Jalaie Shohreh 
Published: May 2024

Background and Aim: Tinnitus, characterized by the perception of sound without the presence of an external auditory stimulus, can profoundly affect the quality of life. This review study aims to assess the role of attention modulation in tinnitus management and investigate the neurophysiological mechanism of attention and its interaction with emotional processing in patients with tinnitus.
Recent Findings: The studies revealed differences in the function of attentional networks among individuals with tinnitus. The studies showed the positive impact of various techniques for attention modulation through direct attention training or indirect mechanisms influencing attention. These techniques could modify attentional biases, enhance attention control, and alleviate tinnitus-related distress.
Conclusion: The results of studies suggest the potential role of attention modulation in tinnitus management. By targeting attentional processes, researchers and clinicians can provide more effective interventions for individuals with tinnitus. However, there is a need for further investigation to optimize the intervention protocols by collaboration between researchers, clinicians, and individuals with tinnitus to achieve success in tinnitus management.
