Authors: Kim Jahyung , Kim Jaeyoung , Kim Saintpee , Yi Young
Published: July 2024

Weight-bearing computed tomography (WBCT) enables acquisition of three dimensional bony structure images in a physiological weight-bearing position, which is fundamental in under-standing the pathologic lesions and deformities of the ankle joint. Over the past decade, re-searchers focused on validating and developing WBCT measurements, which has significantly enhanced our knowledge of common foot and ankle disease. Consequently, understanding the application of WBCT in clinical practice is becoming more important to produce improved out-comes in the treatment of disease around the ankle joint. This review will describe an overview of what is currently being evaluated in the foot and ankle surgery using WBCT and where the course of research will be heading in the future.

Purpose: We aimed to develop a nomogram able to predict treatment failure, skeletal events and overall survival (OS) in patients with castration-resistant prostate cancer with bone metastases (CRPC-BM) treated with Radium-223 dichloride (223Ra).
Patients and Methods: Patients from Castilla-La Mancha Spanish region was prospectively included in ChoPET-Rad multicenter study, from January 2015 to December 2022. Patients underwent baseline, interim, and end-of-treatment bone scintigraphy (BS) and 18F-Fluorocholine PET/CT (FCH PET/CT) scans, obtaining multiple imaging radiomics as well as clinical and biochemical variables during follow-up and studying their association with the previously defined end-points. Survival analysis was performed using Kaplan-Meier method and Cox regression. Multivariate logistic and Cox regression models were calculated, and these models were depicted by means of nomograms.
Results: Median progression-free survival (PFS) and OS for our population were 4 and 14 months (mo), respectively. The variables that showed the most robust independent significant association with therapeutic failure were baseline alkaline phosphatase (AP) levels (p=0.022) and the characteristics of BM on CT portion of PET/CT (p=0.017). In the case of OS, the significant variables were therapeutic failure (p=0.038), the number of lines received after 223Ra (p

Background: The safety and effectiveness of factor-Xa (FXa) inhibitors for nonvalvular atrial fibrillation (NVAF) remains inconclusive. We investigated the current dosing of rivaroxaban, apixaban and edoxaban by monitoring drug plasma concentration (PC) and coagulation activity.
Methods and Results: This multicenter clinical study monitored the drug PC levels and two coagulation biomarkers (fibrinogen: FIB, and fibrin monomer complex: FMC) at peak and trough timing in 268 outpatients receiving rivaroxaban (n = 72), apixaban (n = 71), and edoxaban (n = 125) for NVAF. Doses were adjusted according to the dose adjustment criteria of each drug. Based on our previous study, each peak drug PC remained below the cut-off level for predicting bleeding events except in eight patients (three on rivaroxaban, two on apixaban and three on edoxaban) in whom bleeding events occurred; among them, two (one each on rivaroxaban and edoxaban) had a peak drug PC below the cut-off level. Drug PCs widely varied from peak to trough, whereas FMC levels remained within the normal range (< 6.1 µg/ml) regardless of PC variation. These finding suggested that the anticoagulant effects of these drugs persisted throughout the day regardless of the drug PC levels, dosage, and frequency of dosing. Regarding the change in peak drug PC levels over time, rivaroxaban tended to accumulate more than edoxaban (p

Published: July 2024

Abstract: Flexible pressure sensors are electronic devices that can be attached to various irregular surfaces to measure the pressure. It is widely used in wearable devices and for health detection. In this study, a general carbon nanotubes/polydimethylsiloxane (CNTs/PDMS) sponge electrode was fabricated as the elementary component of the compressible system. The sensitivity of the flexible pressure sensor is improved by optimizing the preparation process of the conductive sponge and surface modification of the CNTs, and the highest sensitivity reached 71.831 kPa-1(0~2 kPa). The flexible pressure sensor can be used to detect subtle pressure quickly and accurately so that it can be used as wearable sensor to measure the radial artery wave of a human body, which has potential applications in health care and other fields.

Published: July 2024

Left-to-right differences in the histopathologic patterns of transthyretin-derived amyloid (ATTR) deposition in the atria of older adults have not yet been investigated. Hence, this study evaluated heart specimens from 325 serial autopsy subjects. The amount of ATTR deposits in the seven cardiac regions, including both sides of atria and atrial appendages, was evaluated semiquantitatively. Using digital pathology, we quantitatively evaluated the immunohistochemical deposition burden of ATTR in the myocardium. We identified 20 sporadic ATTR cardiac amyloidosis cases (9 males). All patients had ATTR deposition in the left atrial regions of the myocardium. In the semiquantitative analysis, 14 of the 20 cases showed more severe ATTR deposition on the left atrial regions than on the right side, with statistically significant differences in the pathology grading (p < 0.01 for both the atrium and atrial appendage). Quantitative analysis further supported the difference. Moreover, six had ATTR deposition in the epineurium and/or neural fibres of the atria. Cluster analysis revealed that ATTR deposition in the myocardium was significantly more severe in males than in females. The heterogeneous distribution of amyloid deposits between atria revealed in this study may impair the orderly transmission of the cardiac conduction system and induce arrhythmias, which may be further aggravated by additional neuropathy in the advanced phase. This impairment could be more severe among males. These findings emphasise that atrial evaluation is important for individuals with sporadic ATTR cardiac amyloidosis, particularly for early detection.

Objectives: Describe the epidemiology of burns in the pediatric population. Analyze and compare the results obtained from the treatment of burn wounds by using the bio-preserved human epidermis allograft (BHEA) and other types of dressings and determine the need for further need of a skin graft. Methods: A retrospective cross-sectional study of pediatric population with burn injuries was conducted, grouped into categories based on their age group, and the mechanisms of injury into 6 categories: scald, flame, contact, electrical, chemical and friction. Describing the extension and depth of the burn injury. The results of treatment of two groups; the patients who used (BHEA) and the group with “other dressings” were analyzed by inferential statistics to establish the relationship between the use of BHEA and the need for skin grafts compared to the other group. Results: A total of 65 patients were obtained. The average age was 4.5 years (±3.8). Preschoolers (1-5 years old) were the most frequent age group 64% (n=42). Male patients represented 61% (n=40) of cases. Scald was the most reported mechanism 64% (n=42). The average total body surface area burned (TBSAB) was 10.8% (± 9.2). Mixed partial thickness burn (superficial and deep) was the most common with a 55%. The head was the most affected anatomical site; 30%. The face was the most reported “special anatomical site” with a 40% (n=30). 32.2 % of the population (n=21) was treated with BHEA. The average time of epithelialization of the BHEA group was 8 days (±7.2), and their average hospital stay time was 7 days (±5.7). In the “other dressing” group, the average epithelialization time was 18 days (±13.6), and the average hospital stay time was 11 days (±12.6). Fifty percent (n=22) of the “other dressing” group required skin grafts. In the BHEA group only 19% (n=4) required skin grafts. An OR of 0.23 and CI of 95% (0.06 – 0.81) with a p value of (0.017) for the need of skin grafts after de use of BHEA was obtained. Conclusion: The epidemiological results reported are similar to those described in the literature. The use of (BHEA) proved to be a good option for the management of partial thickness burns and burns in transition, promoting timely epithelilization and avoiding deepening of the burns while reducing morbidity, hospital stay and care costs.
Correlations between Symmetry and Frequency of Artificial and Natural Symbols
Authors: Bormashenko Edward , Shoval Shraga , Frenkel Mark , Nosonovsky Michael
Published: July 2024

We report positive correlations between letter frequency and symmetry (more symmetric symbols are more frequent) in English and Russian languages and in four types of numerals (Western, Roman, Arabic, and Chinese) with the coefficients of determination of R2=0.899 (English), R2=0.693 (Russian) and R2=0.740 (numerals). For comparison, we studied "symbol-like" 2D colloidal clusters and found negative correlations between frequency and symmetry (R2=0.814 and R2=0.994). While in human-made systems the frequency of using of a symbol is the driving force which leads to symbols simplification and symmetrizing, in natural system, symmetry leads to lower frequency of occurrence because there are fewer ways of building symmetric clusters than asymmetric ones. We interpret these results as a correlation between the symbol as a type and as a token and we attribute this correlation to the inherent iconicity of symbols

Rethinking the Limits of Polycentric Governance: Towards a More Inclusive Innovation Ecosystem Framework for Sustainable Development in the Global South
Authors: Moleka Pitshou
Published: July 2024

Polycentric governance, as conceptualized by the Nobel Laureate Elinor Ostrom, has been widely celebrated as a promising approach to fostering inclusive innovation ecosystems in the Global South. By emphasizing the coordination of multiple decision-making centers and the engagement of diverse stakeholders, polycentric systems are believed to enhance the inclusivity and responsiveness of innovation processes, crucial for addressing societal challenges and promoting equitable development. However, this article argues that the theoretical and practical application of polycentric governance may not adequately address the inherent power structures and complexities within inclusive innovation ecosystems. Drawing on critical analysis, empirical evidence, and complementary theoretical perspectives, this paper interrogates the limitations of polycentric governance and proposes a more nuanced, multidimensional framework for inclusive innovation governance in the context of the Global South.

Published: July 2024

Cardiovascular complications are the major cause of diabetes-related morbidity and mortality. Increased renin-angiotensin-aldosterone system activity and decreased β-adrenergic receptor (β-AR) responsiveness contribute to diabetic cardiac dysfunction. We evaluated the effect of sacubitril/valsartan (neprilysin inhibitor plus angiotensin receptor antagonist combination), and valsartan treatments on the diabetic cardiac function through β-AR responsiveness, and on protein expression of diastolic components. 6-week-old male Sprague-Dawley rats were divided into control, diabetic, sacubitril/valsartan (68 mg/kg), and valsartan treated (31 mg/kg) diabetic groups. Diabetes was induced by high fat diet plus low dose streptozotocin (30 mg/kg, intraperitoneal). After 10 weeks of diabetes, rats were treated for 4 weeks. Systolic/diastolic function was assessed by in vivo echocardiography and pressure-volume loop analysis. β-AR mediated responsiveness was assessed by in vitro papillary muscle and Langendorff heart experiments. Protein expression of sarcoplasmic reticulum calcium ATPase2a, phospholamban, and phosphorylated phospholamban was determined by Western blot. Sacubitril/valsartan improved ejection fraction and fractional shortening to a similar extent as valsartan alone. None of the treatments affected in vivo diastolic parameters or expression of related proteins. β1-/β2-AR mediated responsiveness was partially restored in treated animals. β3-AR mediated relaxation responses were comparable among groups. The beneficial effect of sacubitril/valsartan on systolic function may be attributed to improved β1-/β2-AR responsiveness.

Published: July 2024

Research on White Etching Cracks (WEC) apparent in multiple bearing applications has identified various drivers to cause them. Lubricants, Electricity combined with contact mechanics are proven to catalyze WEC significantly. However, none of them is solely causing WEC by its own, instead combinations discretize whether WEC appears or not. Hence, the WEC topic appears to be multidimensional, making WEC still unpredictable. The current paper is about a systematic study by the use of a DGBB test rig on how lubricant chemicals combined with electricity and by varying oil flow and pressure lead to WEC. It becomes evident, that even WEC critical conditions turn to be WEC free by simply increasing the oil flow and decrease the contact pressure.

ABSTRACT
Purpose: To report a novel application of excimer ablation for normalization of central corneal refractive irregularity, combined with higher fluence CXL in the effective management and visual rehabilitation of progressive keratoconus. Methods: 17 cases with progressive keratoconus were treated with a corneal surface excimer laser ablation normalization using the topography-guided (Contura) myopic ablation for customized corneal re-shaping using a 6mm optical zone. The epi-thelial removal was accounted for by adding a -2.75 diopters correction in the topography-guided normalizing surface ablation followed by, a second, wavefront-optimized hyperopic excimer treatment of + 2.75 diopters at 6mm optical zone. The 2 sequential excimer ablations were fol-lowed by the corneal crosslinking (CXL). Visual acuity, refraction, and keratoconus documentation via keratometry, topography, and pachymetry, as well as endothelial cell density were evaluated over 36 months. Results: Keratoconus stabilized in all cases. The severity of keratoconus stage by Amsler-Krumeich criteria improved for the OD from an average 2.2 to 1. Mean UDVA showed marked improvement at one-year follow-up all values in decimal: from 0.21±0.18 pre-operative to 0.51±0.25 at 12 months, with small additional improvement through the 3 years to 0.51±0.16. CDVA respectively increased from 0.55±0.11 to 0.77±0.14 at 1 year, and to 0.79±0.16 at 3 years. Mean minimal corneal thickness decreased significantly from 466.74±34.25 μm to 396.17±45.17 μm (P

Published: July 2024

Inflammatory bowel disease (IBD) is an incurable, chronic disorder of the gastrointestinal tract, whose incidence increases every year. Scientific research is constantly delivering new information about the disease and its multivariate, complex etiology. Nevertheless, full discovery and understanding of the complete mechanism of IBD pathogenesis still pose a significant challenge to today's science. Recent studies unanimously confirmed the association of gut microbial dysbiosis with IBD, as well as its contribution to the regulation of the inflammatory process. It transpires that not only the altered composition of pathogenic and commensal bacteria is characteristic of disturbed intestinal homeostasis in IBD, but also of viruses, parasites, and fungi, which are active in the intestine. In fact, the crucial function of microbial metabolome in the human body is altered, which causes a wide range of effects in the host, thus providing a basis for the disease. On the other hand, human genomic and functional research revealed more loci that play an essential role in gut homeostasis regulation, immune response, and intestinal epithelial function. This review aims to organize and summarize currently available knowledge concerning the role and interaction of crucial factors associated with IBD pathogenesis, particularly host genetic composition, intestinal microbiota, and metabolome, with immune regulation.

Deploying search and rescue (SAR) dogs in disaster situations is crucial for effective rescue missions. This study delves into the challenges and obstacles encountered during the use of SAR dogs, particularly focusing on the earthquake that hit Turkey in February 2023. By employing a case study approach, the research explores various factors that impact the efficiency and safety of SAR dog operations, such as environmental conditions, equipment needs, cultural perceptions, and logistical hurdles. Environmental conditions such as extreme weather, hazardous materials, and unstable structures present significant risks to both the dogs and their handlers. The adequacy of equipment, including protective gear and medical supplies, is critical for ensuring the safety and efficiency of rescue operations. Logistical challenges, including the transportation and care of dogs in disaster zones, further complicate their deployment. Cultural barriers also play a crucial role, as perceptions of dogs vary widely across different communities, potentially affecting the acceptance and integration of canine units in rescue efforts. The case study of the earthquake in Turkey highlights these issues, showcasing the successes and setbacks experienced by international rescue teams. The findings indicate that although SAR dogs are invaluable in locating survivors, they face significant dangers, including hazardous materials, extreme weather, and physical injuries. Additionally, cultural differences and logistical issues complicate their deployment. This paper highlights the necessity for improved training, protective measures, and international standards to ensure SAR dogs' well-being and effectiveness in disaster response efforts. The study's implications suggest that addressing these challenges can markedly enhance the preparedness and resilience of SAR teams, leading to more efficient and safer rescue operations in future disaster scenarios.

Beta Distribution Function for Cooperative Spectrum Sensing Against Byzantine Attack in Cognitive Wireless Sensor Networks
Authors: Wu Jun , Liu Tianle , Zhao Rui
Published: July 2024

In order to explore more spectrum resources to support sensors and its related applications, cognitive wireless sensor networks (CWSNs) have emerged to identify available channels being underutilized by the primary user (PU). To improve the detection accuracy of the PU signal, cooperative spectrum sensing (CSS) among sensors paradigm is proposed to make a global decision about the PU status for CWSNs. However, CSS is susceptible to Byzantine attack from malicious sensor nodes due to its open nature, resulting in wastage of spectrum resources or causing harmful interference to PUs. To suppress the negative impact of Byzantine attack, this paper proposes a beta distribution function (BDF) for CSS among multiple sensors, which includes a sequential process, beta reputation model, and weight evaluation. Based on sequential probability ratio test (SPRT), we integrate the proposed beta reputation model into SPRT, while improving and reducing the positive and negative impacts of reliable and unreliable sensor nodes on the global decision, respectively. Finally, the numerical simulation results demonstrate that compared to SPRT and weighted sequential probability ratio test (WSPRT), the proposed BDF has outstanding effects in terms of the error probability, and average number of samples under various attack ratios and probabilities.

Word Decoding Ability In The World Of Language Acquisition Process: A Literature Review
Authors: Abernathy Peter
Published: July 2024

The ability to decode words accurately at an early age strongly predicts reading competence later on. Decoding-challenged children may find it difficult to understand texts, which might impede their overall academic development. Strong word decoding skills accelerate the process of learning vocabulary and grammar rules in a variety of languages. The paper aimed to collect relevant literature regarding word decoding ability in the world of the language acquisition process. Policymakers and educators will be greatly impacted by realizing how crucial word decoding is to language learning. Providing targeted interventions for struggling readers, encouraging a positive reading culture, and explicitly teaching phonological and orthographic abilities are all essential components of effective reading education. Promoting decoding proficiency also requires making sure that people have access to excellent reading materials and tools. In order to enable learners to become great readers and communicators across linguistic and cultural boundaries, educators and policymakers should prioritize phonemic awareness from an early age and use effective teaching methodologies.

Human hair is characterised by significant variability, determined by genetic and macromolecular factors. Whilst European hair type has been a focus of extensive research, Afro-textured hair care faces challenges created by insufficient knowledge of its unique properties. Applications of hair care products that are incompatible with Afro-textured hair frequently have detrimental effects on the scalp, including alopecia. This highlights the need for scientific and clinical partnerships to bridge the gap between research and hair care practices and address challenges related to Afro-textured hair. In this review, we performed data mining of the existing literature and in-silico network analysis of the biomarkers relevant to Afro-textured hair. The approaches to hair maintenance are highlighted in the context of hair anatomy and growth cycles, organisation of keratins, surface lipids and chemical bonds. We discuss a range of biomarkers affecting hair fibre's shape and mechanical strength, with the gene interactive network pointing to the hierarchical organisation of important traits, notably hair shaft diameter, keratinisation, hair follicle development and patterning. We propose a better understanding of the genetic traits, molecular structure and biomechanics of Afro-textured hair is required to initiate more effective hair care solutions that would benefit the wider population.
Nicotinamide Riboside – What It Takes to Incorporate It into RNA
Authors: Wenzek Felix , Biallas Alexander , Müller Sabine
Published: July 2024

Nicotinamide is an important functional compound and, in the form of nicotinamide adenine dinucleotide (NAD), is used as a cofactor by protein-based enzymes to catalyze redox reactions. In the context of the RNA world hypothesis, it is therefore reasonable to assume that ancestral ribozymes could have used cofactors such as NAD or its simpler analog nicotinamide riboside (NAR) to catalyze redox reactions. The only described example of such an engineered ribozyme uses a nicotinamide moiety bound to the ribozyme through non-covalent interactions. Covalent attachment of NAR to RNA could be advantageous, but the demonstration of such scenarios to date has suffered from the chemical instability of both NAR and its reduced form NARH, making their use in oligonucleotide synthesis less straightforward. Here, we review the literature describing the chemical properties of the oxidized and reduced species of NAR, their synthesis, and previous attempts to incorporate either species into RNA. We discuss how to overcome the stability problem and succeed in generating RNA structures incorporating NAR.
Discovery of a Buried Active Fault to the South of the 1679 M8.0 Sanhe–Pinggu Earthquake in the North China Plain: Evidence from Seismic Reflection Exploration and Drilling Profile
Authors: Li Zhengfang , Zhou Bengang , Li Yanbao
Published: July 2024

This study focuses on the key structural locations to the south of the 1679 M8.0 Sanhe–Pinggu earthquake. In conjunction with prior deep seismic reflection exploration in the area, we conducted four shallow seismic investigations to the south of Sanhe–Pinggu seismic area to delineate the exact structure of identified faults and to ascertain the precise location, characteristics, and activity levels of active faults within the region. By analyzing the burial depth of the fault’s breakpoint as revealed by high-precision shallow seismic profiles, we postulate that the fault has been active since the middle and late Pleistocene epochs. In addition, we conducted a high-density borehole investigation in tandem with composite drilling profile at the corresponding sites of shallow breakpoints. Using chronological data from neighboring boreholes and accounting for the ages of samples acquired from these boreholes and staggered strata, the fault manifests as a Holocene active fault within the composite borehole–geological section. This study contradicted the previous conception that to the south of 1679 Sanhe–Pinggu seismic area contained no active faults. This new discovery not only has significant application value for evaluating the risk of large earthquakes in the southern part of the capital circle and understanding the earthquake disaster risk in Beijing but also has scientific significance for studying the development and evolution of faults and their deep–shallow coupling characteristics in North China since the late Cenozoic.
Sodium hypochlorite as an Artificial Exsheathment Medium for Nematode Larvae: Limitations for Application
Authors: Elowni Elsayed E. , Abdelnabi Ghada H. , Ahmad Mohamed F.
Published: July 2024

Sodium hypochlorite (NaOCl) has largely been used as an artificial exsheathment medium for nematode larvae in various studies such as evaluating the efficacy of anthelmintic drugs, assessing the resistance of nematodes to anthelmintics, evaluating plant bioactive products as anthelmintics, or in nematode viability assays because of its unique capacity for tissue dissolution. Doubts, however, exist that the compound affects the viability of the exsheathed larvae. The present study’s objective was to exclude or confirm possible negative effects of the compound using strongylid third-stage larvae of donkeys’ origin. Visual larval immobility and gross morphological changes were adopted as criteria for assessment of viability following treatment of larvae with 0.025, 0.05, 0.1, 0.2, 0.3, or 3% NaOCl solutions. Larvae were examined 10, 5, or 3 min after treatment. The results indicate there is a threshold beyond which viability is impaired. A concentration of 0.025% produced no effect on the viability of larvae (the optimum concentration) for as long as 10 min following treatment (the effective time). It is proposed that in situations where the optimum concentration has been determined, it is necessary to establish if exsheathment can be produced within the respective effective time limit.

Keloid is benign skin tumor, and their curing is relatively difficult due to the unclear mechanism of formation. Inducing ferroptosis of keloid fibroblasts (KFs) may become a new method for treating keloid. Here, we discover interferon (IFN)γ could induce KFs ferroptosis through inhibiting SPOC domain-containing protein 1 (SPOCD1), serving as a mode of action for CD8+T cell (CTL)-mediated keloid killing. Mechanistically, keloid IFNγ deficiency in combination with reduced DNMT3A increase the expression of SPOCD1, thereby promoting KFs’ proliferation and inhibiting its ferroptosis. Moreover, keloid SPOCD1 deficiency attenuates KFs progression and extracellular matrix (ECM) deposition. Reducing IFNγ and SPOCD1 simultaneously can increase the positive rate of reactive oxygen species (ROS) and promote mitochondrial shrinkage. Ex-vivo explant keloid culture has also confirmed that the reduction of SPOCD1 helps to reduce the proliferation rate of KFs, inhibit the angiogenesis of keloid scars, and thus inhibit keloid formation. Thus, IFNγ signaling paired with SPOCD1 is a natural keloid ferroptosis promoting mechanism and a mode of action of CTLs. Targeting SPOCD1 pathway is a potential anti-keloid approach.
