Cultural space as a factor in the formation of value orientations of young people
Authors:   Moscow Aviation Institute (National Research University), Mikhaylova Ekaterina O.
Published: July 2023

The article considers the role of cultural space in the formation of value orientations of modern youth. The vectors of the influence of cultural space on the formation of value orientations were analyzed, three levels of the influence of cultural space on the formation of value orientations (macro, meso and micro levels) were characterized. The influence of cultural space can be significant, but not always consistent with the dominant values of society. In this regard, it is necessary to study the forms, methods and mechanisms of this influence, and not reject its existence. The direct impact of cultural space on the process of forming youth value orientations consists in conscious self-regulation of individual value orientations of young people in a specific sociocultural environment of society. The main characteristics of the modern cultural space of Russian youth should be used as a basis for the formation and implementation of youth policy, respectively. Such characteristics include: blurred boundaries (including the boundaries of social norms), reduction of high culture in favor of mass consumer and virtualization of interaction with cultural objects.

The individual-author myth about Leo Tolstoy in M. Gorky’s essay “Leo Tolstoy” (To the problem of Tolstoy’s text in M. Gorky’s work)
Authors:   Vernadsky Crimean Federal University, Kurianova Valeria V.
Published: July 2023

In the article on the material of M. Gorky’s essay “Leo Tolstoy” elements of Tolstoy’s text as a named supertext of literature are considered. It is stated that the basis of this text is a myth about Leo Tolstoy, which has been actively developing for a century and a half, but takes on a particular relevance in the early 20th century during the popularization of the spiritual heritage of the writer and the understanding of his tragic departure from Yasnaya Polyana. The Tolstoy text in the works of M. Gorky is extensive, with mythologized constant representations appearing in almost all of the writer’s fiction texts. The intermediate result of the writer’s mythologizing of Leo Tolstoy’s personality was an essay about him with the same name. This research shows how exactly in this publicist text Gorky creates his own unique myth of Leo Tolstoy, which reflects both the particular attitude of his younger contemporary to the great Russian writer, and his own beliefs about the contradictions and ambiguities of the real genius. Attention is focused on the uniqueness of Tolstoy’s text in the work of “the first proletarian writer”. The Tolstoy myth, as any other myth, can have a sacred or profane nature, in the essay M. Gorky combines both directions.
Roberto Civita
Authors: Carletti Vitor
Published: July 2023

A resenha faz uma leitura crítica do livro Roberto Civita: o dono da banca. A vida e as ideia do editor da Veja e da Abril. Propõe-se situar a biografia escrita pelo jornalista Carlos Maranhão no contexto da globalização a partir da definição elaborada por Santos (2000). O argumento é a que obra coloca Civita como um empresário de sucesso que pautou a opinião pública, mas que não foi capaz de entender o funcionamento da sociedade em rede, de acordo com a definição de Castells (2003). Além disso, o livro relata como o dono da Veja era responsável por colocar os interesses econômicos acima dos valores deontológicos da profissão (KOVACH; ROSENSTIEL, 2004) sem, no entanto, deixar para o leitor essa transgressão da ética jornalística evidente. A obra, portanto, possui um valor de memória e é rica em informações obtidas por meio de entrevistas e pesquisa no acervo da Editora Abril, mas deixa de mencionar os processos judiciais contra a empresa.

Introdução: O contexto pandêmico tem implicações diretas na situação de segurança alimentar e nutricional atual e futura, assim é urgente avaliar a situação da insegurança alimentar em suas diferentes dimensões. Há poucos estudos que avaliam conjuntamente segurança alimentar, disponibilidade e acesso aos alimentos. Objetivo: Descrever a disponibilidade alimentar domiciliar e o acesso percebido aos alimentos segundo a situação de insegurança alimentar em domicílios de escolares na pandemia de COVID-19. Métodos: Trata-se de um estudo transversal com amostra representativa de domicílios de escolares da educação infantil e ensino fundamental de escolas públicas de Mariana e Ouro Preto, Minas Gerais. Os dados foram coletados na fase inicial da pandemia, “junho e julho de 2020”, por meio de entrevistas telefônicas com os responsáveis por comprar e/ou preparar os alimentos nos domicílios. Investigou-se condições socioeconômicas, acesso percebido aos alimentos, disponibilidade alimentar domiciliar e insegurança alimentar, esta avaliada por meio da Escala Brasileira de Insegurança Alimentar. Resultados: Dos 612 domicílios investigados, 82,0% estavam em situação de insegurança alimentar, sendo 11,3% em insegurança moderada e 5,1% em insegurança grave. Foi observada relação entre disponibilidade de frutas, hortaliças, leite, carnes e ovos com a insegurança alimentar, bem como com a percepção de dificuldade no acesso a frutas e hortaliças. Discussão: A situação de insegurança alimentar enfrentada pelos domicílios relaciona-se com menor disponibilidade de alimentos importantes para o desenvolvimento dos escolares, ademais as famílias depararam com inacessibilidade para adquirir frutas e hortaliças.

La lesión autoinfligida es un acto intencional de hacerse daño sin propósito suicida. El presente caso describe a un paciente esquizofrénico de 37 años de edad, que ha padecido 20 años con la enfermedad, y síntomas recientes de irritabilidad, agresividad, aislamiento, ideas de perjuicio y contaminación («tengo un estafilococo en mi cabeza»). Durante 10 años utilizaba varios objetos, incluido un bisturí con el que llegó a remover (extirpar) parte de la calota, ocasionando un edema vasogénico en la región córtico-fronto-parietal izquierda que produjo hemiparesia braquiocrural derecha y motivó su admisión. Luego de descartarse un accidente cerebrovascular o tumor cerebral, fue intervenido quirúrgicamente para la extracción de un absceso cerebral. Recibió varios fármacos antipsicóticos con respuesta parcial, y más tarde mejoró con la administración de paliperidona. En casos como este, es necesario un tamizaje, diagnóstico y tratamiento oportunos para evitar evolución y pronóstico tórpidos en pacientesesquizofrénicos con lesiones autoinfligidas y con historia de pobre respuesta y adherencia al tratamiento.
Elucidating the Potential of Biochar-bentonite Composite and Kaolinite-based Seed Balls for the Remediation of Coal Mining Impacted Heavy Metals Contaminated Soil
Authors: Medha Isha , Chandra Subhash , Bhattacharya Jayanta
Published: July 2023

Globally, open-pit coal mining is associated with severe land use impact and contamination of soil and water resources with heavy metals. Thus, in growing economies like India, where coal is a significant energy source, the heavy metals contamination of soil and water become ubiquitous. Remediation of such a large stretch of mined-out land is a major challenge and a costly process for the mining industry. In recent years, the application of biochar for the remediation of such heavy metals-contaminated soil has been widely practiced. However, applying biochar and cultivating plants in field conditions becomes challenging.

This study uses a unique remediation approach by developing biochar-bentonite-based seed balls encapsulating Shorgham grass seeds at their core for application in the contaminated soil. The seed ball was developed by using the bentonite biochar composite in varying weight fractions of 0.5 – 5 % with respect to the kaolinite, whose fractions in the seed ball also varied at one, three, and five parts. The seed balls were applied to the pots containing 3 kg of heavy metals contaminated soil for a pot-culture study in a polyhouse for a period of four months. Initial soil analysis results indicated that the mine soil samples showed poor nutrient and organic matter content and were contaminated with heavy metals such as Ni, Zn, Cr, and Cd. Post-pot-culture soil analysis results indicated that the application of seed balls containing five fractions of biochar composite with its combination with three and five-weight fractions of kaolinite showed substantial improvement in the pH, available nutrients, organic matter content, soil enzymes, and overall soil fertility index compared to the controlled study and other cases. The same combination of seed balls also significantly reduced the plant-available fractions of Ni, Zn, Cr, and Cd in the soil and the translocation of these heavy metals from the rhizosphere zone to the grass’s aerial parts, indicating stabilization of heavy metals within the soil matrix. Moreover, the application of seed balls also substantially improved the plant physiology and reduced the release of stress hormones such as proline and glutathione within the plant cells indicating improvement in the plant’s biotic and abiotic stress factors. Thus, the application of seed balls in heavy metals contaminated soils, particularly over a large stretch of land, could be a low-cost and viable remediation technique.
Effectiveness of Travelling Slice Modeling in Representing the Continuous Casting Process of Large Product Sections
Authors: Bazzaro Gianluca , De Bona Francesco
Published: July 2023

In metal continuous casting process is important to estimate the temperature evolution of casted section along machine from meniscus (point in which liquid metal is poured) to cutting machine where product is cut at commercial length. Particularly in the case of large sections, a convenient approximated model to achieve this goal with a feasible computational effort, is the so called travelling slice: the transversal section of casted product is subjected to different thermal boundary conditions (e.g. thermal flux, radiation, convection) that are found during the movement at constant speed from meniscus to the end of machine. In the case of an axisymmetric section, a comparison with the exact solution can be easily achieved. The article will show pros and cons of both, namely the far lower computational cost of travelling slice model without losing precision. Results confirm the validity of the travelling slice approach also at low casting speed and huge dimensions.
Enhancing Intrusion Detection in 5G and IoT Environments: A Comprehensive Machine Learning Approach Leveraging AWID3 Dataset
Authors: Salah Zaher , Abu Elsoud Esraa
Published: July 2023

Internet users have significantly increased as a result of the spread of Internet of Things (IoT) technologies and 5G networks. But these developments also make people more susceptible to cybercrime. Intrusion detection systems (IDSs), which protect against cyber threats and facilitate early response, have emerged as crucial security measures to handle this expanding risk. This study intends to present a comprehensive review of IDS, how it interacts with machine learning (ML), and develop a suitable approach for attack detection in 5G and IoT environments. To accomplish this, we leverage the AWID dataset, which is the first wireless traffic dataset specifically designed for security purposes, focusing on the IEEE 802.11 standard and developed to the AWID3 dataset. In this research, we suggest a powerful machine-learning framework for wireless system intrusion detection. We perform evaluations in three stages, covering scenarios for multiple nominal classes, multiple numeric classes, and binary classes. In order to improve the performance of the intrusion detection model, we also use feature selection approaches. Additionally, we offer a model that incorporates the outcomes of three feature selection techniques, highlighting how crucial it is to comprehend the features present in wireless datasets. Our experiments demonstrate how a machine learning-based approach can detect attacks with a high level of accuracy. In particular, the boosted decision tree performs best when overlapping feature selection procedures, whereas the Logistic Regression approach obtains the maximum accuracy of 99% in the first two phases. By providing a comprehensive framework for identifying attacks in 5G and IoT contexts using machine learning approaches, this research makes a contribution to the field of intrusion detection. The results underline how important it is to comprehend wireless dataset characteristics and highlight the possibility of ML-based methods for attaining highly accurate intrusion detection.
Variation Trend of Runoff and Sediment Transport in the Jinsha River Basin and the Impact of Large Reservoirs
Authors: Wang Suiji , Wang Xumin
Published: July 2023

For the purpose of clean energy hydropower development, the construction of reservoirs has been continuously promoted in the Jinsha River basin for many years, and how the reservoirs affect the water and sediment process is a very necessary topic to study. This study is based on the gauged water and sediment data (span from the 1960’s to 2020) at Shigu, Panzhihua, and Xiangjiaba stations downstream located in the trunk channel of the river, and uses Mann-Kendall trend test method and double cumulative curve method to comprehensively judge the variation trends of runoff and suspended sediment load and reveal their credible mutation years. The linear regression method is used to reveal the variation characteristics of the relationship between water and sediment before and after the abrupt change years. The results show that the variations in runoff at Shigu and Panzhihua stations have significant and relatively obvious increasing trends, respectively, and that at Panzhihua station has a mutation year of 1985. The runoff at Xiangjiaba Station slightly increased but not significantly. The variation of suspended sediment load showed a temporal and spatial differentiation. The variation of sediment discharge at Shigu Station showed an increasing trend with a mutation year of 1997. For Panzhihua Station, it showed an increasing trend before 1998, but has significantly decreased since 1998. The fluctuation of sediment transport at Xiangjiaba Station was significant before 1998, but the trend is unclear. In the period of 1998−2020, it showed a significant decreasing trend, especially since 2013, when the mean annual suspended sediment load only accounted for 0.61% of its multi-year average. The variations of mean annual sediment concentration and sediment inflow coefficient at the hydrological stations is consistent with the variation trend of sediment transport. Before 2013, the correlation between water and sediment was strong, but thereafter it was extremely weak. The two sudden years of 1998 and 2013 are consistent with the year when large reservoirs were built in the river basin. The construction of large reservoirs and their large amount of sediment retention are the key reasons for the sudden changes in the water-sediment relationship and the sharp decrease in sediment transport in the downstream reach of the reservoir dam. The climate and underlying surface changes in the study area are not significant, and their impact on the water and sediment processes in the watershed is limited.

Published: July 2023

This review emphasizes the significance of dietary carotenoids in promoting skin health and appearance. The applications of carotenoids in health-promoting and nutrient products and their potential health effects are discussed. Food technology, health, nutrition, dermatology, and dermoaesthetics have recently focused on colorless carotenoids, particularly phytoene, and phytofluene, which have the unique ability to absorb UV radiation. These carotenoids, being significant components of the human diet, are readily bioavailable and have demonstrated various health-promoting actions in re-cent studies. Their distinct structures and properties, such as light absorption, oxidation sensitivity, stiffness, aggregation tendency, and even fluorescence in the case of phytof-luene, contribute to their potential benefits. Furthermore, it is recommended to assess the levels of these carotenoids to evaluate skin carotenoid status accurately.

Published: July 2023

Objective: To evaluate the effect of care bundles on treatment compliance and intestinal barrier function in patients with refractory septic shock in the intensive care units (ICUs). Methods: In this retrospective study, the clinical data of 94 patients with refractory septic shock admitted to our hospital between June 2020 and April 2022 were collected. Patients with routine nursing were included in the routine group, and those with care bundles were assigned to the care bundles group, with 47 cases in each group. Outcome measures included nursing efficiency, treatment compliance, sequential organ failure assessment (SOFA) score, acute physiology and chronic health evaluation (APACHE II) score, intestinal barrier function, inflammation factor level, treatment outcome and complications. Results: Care bundles resulted in significantly higher nursing efficiency and treatment compliance versus routine care (P<0.05). Patients receiving care bundles showed significantly higher SOFA scores and APACHE II scores than those receiving routine care (P<0.05). Intestinal fatty-acid binding protein (I-FABP), diamine oxidase (DAO), lactate, endotoxin, and intestinal dysfunction scores in the care bundles group were significantly lower than those in the conventional group after treatment (P<0.05). Care bundles were associated with significantly lower levels of procalcitonin (PCT) and hypersensitive C-reactive protein (hsCRP), shorter time to symptom relief, ICU treatment time, and duration of mechanical ventilation, and lower 28-d morbidity and mortality versus routine care (P<0.05). Patients in the care bundles group had a significantly lower incidence of complications than those in the routine group (P<0.05). Conclusion: Care bundles effectively enhance treatment compliance, improve intestinal barrier function and treatment outcomes, reduce the inflammatory response, and decrease the risk of SOFA score, APACHE II score, and complications in patients with refractory septic shock.

Four leather substrates from different animals were treated by dispersions containing hydrophilic composite silica-hyperbranched poly(ethylene imine) xerogels. Antimicrobial activity was introduced by incorporating silver nanoparticles and /or benzalkonium chloride. The gel precursor solutions were also infused before gelation to titanium oxide powders typically employed for induction of self-cleaning properties. The dispersions from these biomimetically premade xerogels integrate environmentally friendly materials with short coating times. Scanning electron microscopy (SEM) provided information on the powder distribution onto the leathers. Substrate and coating composition were estimated by infrared spectroscopy (IR) and ener-gy-dispersive X-ray spectroscopy (EDS). Surface hydrophilicity and water permeability were assessed by water-contact angle experiments. The diffusion of the leather's initial components and xerogel additives into the water were measured by Ultraviolet-Visible (UV-Vis) spectroscopy. Protection against GRAM- bacteria was tested for Escherichia coli, Pseudomonas aeruginosa, and Klebsiella Pneumoniae against GRAM+ bacteria for Staphylococcus aureus, and Enterococcus faecalis and against fungi for Candida albicans. Antibiofilm capacity experiments were performed against Staphylococcus aureus, Klebsiella Pneumoniae, Enterococcus faecalis, and Candida albicans. The application of xerogel dispersions proved an adequate and economically feasible alternative to the direct gel formation into the substrate’s pores for the preparation of leathers intended for medical uses
Further characterization of the polycrystalline p-type β-Ga2O3 films grown through thermal oxidation of GaN at 1000 to 1100 °C in N2O atmosphere

Published: July 2023

The development of good conductivity p-type β-Ga2O3 is critical to realize its devices and applications. The nitrogen-doped p-type β-Ga2O3 films with enhanced conductivity characteristics were prepared through the thermal oxidation of GaN in the N2O atmosphere. Further measurements were performed on the oxidized films at 1000, 1050, and 1100 °C to have insight into the underlying mechanism of the thermally activated transformation process. The room temperature photoluminescence (PL) spectra demonstrated a moderate ultraviolet emission peak at 246 nm, confirming the generation of gallium oxide with a band gap of ~5.0 eV. The normalized X-ray diffraction (XRD), the high-resolution transmission electron microscopy (HRTEM), and the selected area electron diffraction (SAED) patterns were used to confirm the characteristic of polycrystalline and anisotropic growth. Then, the effects of the oxidation temperature on the amount of incorporated nitrogen were analyzed using secondary ion mass spectrometry (SIMS). Moreover, the ionization energy of the acceptor of films oxidized at 1000, 1050, and 1100 °C was calculated and analyzed using the temperature-dependent Hall test results. The results showed that nitrogen doping was the main contributor to p-type electrical properties. The activation energy of the polycrystalline β-Ga2O3 prepared through thermal oxidation of GaN in the N2O atmosphere was estimated to be 147.175 kJ·mol-1 using the Arrhenius plot, which was considerably lower than that of both dry and wet oxidations of GaN in O2 ambient, thus confirming the efficiency of thermal oxidation of GaN in N2O.

Published: July 2023

This paper deals with the analysis of the temperatures in a group of 36 African countries. By looking at the maximum, minimum and the range (the difference between the maximum and the minimum) and using a long memory model based on fractional integration and cointegration, we first show that all series display a long memory pattern, with a significant positive time trend in 29 countries for the maximum temperatures and in 33 for the minimum ones. Looking at the range, the estimated value for the order of integration is smaller than the one based on maximum or minimum temperatures in 17 countries. Performing fractional cointegration tests between the maximum and minimum temperatures, our results indicate that the two series cointegrate in the classical sense (i.e., with a short memory equilibrium relationship) in a group of 11 countries, and there is another group of eight countries displaying cointegration in a fractional sense. The remaining 17 countries with no evidence of cointegration are therefore at the very high risk of climate change due to the absence of long-term comovement in their maximum and minimum temperatures. Findings in this paper are of tremendous interpretations and relevance for the analysis and climate projections in Africa.

Published: July 2023

Wet gap crossings are one of the most complex maneuvers undertaken by military engineers, who, along with engineer planners, require better tools to increase the capacity for efficient use of limited bridging resources across the battlespace. Planning for bridging maneuvers often involves a complicated and inefficient system of ad hoc spreadsheets combined with an overreliance on the personal experience and training of subject matter experts (SMEs). Bridge Resource Inventory Database for Gap Emplacement Selection (BRIDGES) uses interactive mapping and database technology in order to streamline the bridging planning process and provide answers to question about myriad scenarios to maximize efficiency and provide better means of data persistence across time and data sharing across operational or planning units.

Published: July 2023

Colorectal cancer (CRC) is a common malignancy, with high incidence and mortality rates. Cuproptosis, a novel form of copper-induced programmed cell death, contributes to tumor progression. Whether cuproptosis-related genes (CRGs) play a role in CRC remains unclear. Here, we systematically assessed CRG mutations in CRC. Seven of the 10 CRGs exhibited significant differential expression between CRC and normal tissues. CDKN2Aand DLAT were identified as independent risk factors for predicting overall survival (OS) in CRC using univariate and multivariate Cox analyses, and a risk score model was constructed based on CDKN2A and DLAT. Patients with CRC were categorized into high- and low-risk groups based on their median risk scores. Patients with CRC in the low-risk group had longer OS than those in the high-risk group. Receiver operating characteristic curve analysis indicated that the risk score model had good predictive accuracy for OS. Spearman’s analysis showed that CDKN2A and DLAT expressions were significantly associated with immune cell infiltration in CRC. Our research revealed CRGs’ prognostic value, particularly CDKN2A and DLAT, in CRC and demonstrated the relationship between CDKN2A/DLAT and immune infiltration in CRC, thereby contributing to the outcome evaluation of patients with CRC and identifying novel targets for CRC immunotherapy.

Horizontal principal stress is a fundamental parameter for reservoir reconstruction of oil and gas wells. For improving single well productivity, accurate evaluation of reservoir stress characteristics is of great importance. One of the main challenges in studying the magnitude of the in situ stress is how to obtain the rock mechanical parameters accurately. In order to solve the problem that conventional methods are not very accurate at predicting the rock mechanical parameters of complex lithology reservoirs, taking transitional shale reservoir rocks as the research object, an intelligent fusion model was proposed to predict rock mechanical parameters. Machine learning algorithms such as the nearest neighbor regression, support vector machine, and random forest were selected to construct intelligent fusion models of different rock mechanics parameters based on the laboratory test data. Finally, the logging profile of transitional reservoir horizontal principal stress in the study area was obtained, under the constraints of the empirical physical model and measured in situ stress data. The results showed that the fusion models have better performance on rock mechanics parameters than the single model and have better accuracy in both training and test sets, which meet the engineering requirements showing accuracy in predicting the horizontal principal stress in the study area.

Published: July 2023

In India, South-west monsoon winds become weak and monsoon withdrawing continuous the month of October. Rainfall during October month is the common phenomenon because October month is of transition from the rainy season to the dry winter conditions, However occasional rainfall activity continuous during the month of October. By the beginning of October 2021, the monsoon withdrew from the Northern Plains. Uttarakhand experienced exceptionally heavy rainfall, which caused floods and severe damage to the economy and human life in the state during 16–20 October, 2021. A deep westerly trough lay between longitude 65.0° E to 70.0° E and a low pressure area over east Rajasthan along with moisture incursion from Bay of Bengal as well from Arabian sea over western Himalayan region (WHR), particularly over Uttarakhand. Moisture incursion from Arabian sea is one of the important factors contributing to heavy rainfall. The case study was conducted using various meteorological observations, wind pattern and weather systems. Current year rainfall pattern and normal rainfall trend is analyzed using rainfall data for October 2021. It is observed that rainfall was received from the 13 stations and all the station of the state received rain heavier than normal rain during 3rd week of October 2021which indicates exceptionally heavy rain generally recurved during 3rd week of October. Actual vs normal rainfall showing R2 0.61 which reveals that 61% of the variability observed in the actual variable is explained by the regression model.

Valosin-containing protein (VCP)/p97, an AAA + ATPase that plays a pivotal role in proteostasis, is a potential therapeutic target for cancer. We report that targeting VCP preferentially kills breast cancer cells over non-transformed cells by inducing paraptosis, a non-apoptotic cell death mode accompanied by the endoplasmic reticulum and mitochondria dilation. We also found that the expression of oncogenic HRas sensitizes non-transformed cells to VCP inhibition-mediated paraptosis. The preferential vulnerability of cancer cells to VCP inhibition is associated with the non-attenuation and recovery of protein synthesis under proteotoxic stress. Mechanistically, mTORC2/Akt activation and eIF3d-dependent translation contribute to this translational recovery and proteotoxic stress enhancement. Additionally, the ATF4/DDIT4 axis enhances VCP inhibition-mediated paraptosis by activating Akt. Considering that hyperactive Akt counteracts chemotherapeutic-induced apoptosis, VCP inhibition may offer a therapeutic opportunity to exploit Akt-associated vulnerability in cancer cells by inducing paraptosis, sparing normal cells.

Aims The aim of the study is to assess non-invasive diagnostic modalities for ocular surface squamous neoplasia, when compared to histology.Methods A prospective case-control study was conducted of patients presenting with conjunctival masses to a tertiary eye hospital in Johannesburg, South Africa. Patients completed an interview and had three non-invasive diagnostic tests: optical coherence tomography, impression cytology and methylene blue stain. A biopsy with histology was performed as the gold standard to confirm the diagnosis.Results One hundred and eighty-two conjunctival masses of 175 patients were evaluated. There were 135 lesions identified as OSSN on biopsy and 47 lesions were benign on histology. Optical coherence tomography had a sensitivity and specificity of 87.2% (95% CI: 80.0–92.5) and 75.6% (95% CI: 60.5–87.1) respectively, when an epithelial thickness cut-off of 140um was used. Shadowing was found in 46% of cases due to leukoplakia or increased thickness of the mass. Cytology had a sensitivity of 72.4% (95% CI: 62.5–81.0) and specificity of 74.3% (95% CI: 56.7–87.5). Methylene blue had a high sensitivity of 91.9% (95% CI: 85.9–95.9), but low specificity of 55.3% (95% CI: 40.1–69.8).Conclusion Optical coherence tomography had a high sensitivity and specificity as a non-invasive test for the diagnosis of OSSN in our population.

In this work, geometric and kinematic modeling of the gear-based crank mechanism engine (GBCM) was performed. To this aim, a mechanical approach based on projective computational methods and mechanism theory laws is applied, to which a parametric study has allowed a conclusion on the geometrical and kinematic behaviors of the moving links. The study concluded that the kinematic quantities at connecting rod head are one-half of those at the piston top head. The extrinsic behavior like the stroke of the connecting rod head is twice the crank radius and the piston kinematic are identical to the conventional engine with the same crankshaft ratio regardless of the compression ratio and any gear wheel radius. Hence, all the extrinsic kinematic properties of a classic crankshaft mechanism of the fixed compression ratio engine remain valid for a gear-based crank mechanism engine and can be used for dynamic calculation purposes.

Published: July 2023

Background
The gonadotropin-releasing hormone (GnRH) stimulation test using intravenously injected gonadorelin is the gold standard for diagnosis of central precocious puberty (CPP). However, gonadorelin is not always readily available.
Objective
This study investigated the diagnostic efficacy of the subcutaneous triptorelin test and the appropriate blood sampling time for diagnosis of CPP.
Methods
We compared clinical data of patients with CPP (n = 74) and premature thelarche (PT) (n = 75) who had been diagnosed with the triptorelin stimulation test (n = 146) versus patients with CPP (n = 3) and PT (n = 37) who had been diagnosed with the gonadorelin stimulation test (n = 74). In the triptorelin test, the luteinizing hormone (LH) and follicle-stimulating hormone (FSH) levels were measured 0, 30, 60, 120, and 180 min (triptorelin 180 min test) and 0, 30, 60, 90, and 120 min (triptorelin 120 min test) after subcutaneous triptorelin injection. In the gonadorelin test, the LH and FSH levels were measured 0, 30, 45, 60, and 90 min after intravenous gonadorelin injection. The clinical parameters of CPP and PT were compared according to the type of stimulant and diagnostic method.
Results
In the triptorelin test group, girls with CPP had a more advanced bone age and higher mean Tanner stage for breast development than girls with PT, whereas in the gonadorelin test group, girls with CPP and PT were not significantly different. In addition, the triptorelin 120 min test group had higher height standard deviation scores than the gonadorelin test group. In the gonadorelin test group, all girls with CPP exhibited a peak LH response at 30 to 60 min after intravenous gonadorelin injection. In the triptorelin test group, most girls with CPP exhibited a peak LH response at > 120 min (n = 38). Among girls with PT, those in the triptorelin 120 min test group had a higher mean Tanner stage for breast development than those in the triptorelin 180 min test group.
Conclusion
The diagnostic efficacy of the triptorelin test is as high as that of the gonadorelin test in diagnosis of CPP. Because of the slower LH response in the triptorelin test, the LH level should be measured over a longer period of time in patients with suspected CPP.
Analysis of the positive effects of crown-of-thorns starfish on the growth and immune system of red sea bream

The crown-of-thorns starfish (Acanthaster planci) feeds on corals, so extermination and other measures are used to protect ecosystems from this predation. However, red sea bream (Pagrus major) reared with crown-of-thorns starfish showed improved growth, increased phagocytic activity of leukocytes, and improved survival in a challenge test using Edwardsiella tarda, which is highly pathogenic to sea bream. These findings suggest that starfish mucus contains a substance that can improve disease resistance in red sea bream. This substance was isolated and identified using nitric oxide (NO) productivity of mouse-derived macrophage cells (RAW264) as an indicator. The immune-activating substance was identified to be a polymeric compound, possibly a polysaccharide. This substance was then purified, resulting in a molecule of molecular weight 1.81 x 105. The monosaccharides in the polysaccharide were identified and quantified, and l-fucose, d-arabinose, d-mannose, d-glucose, d-galactose, N-acetyl-d-glucosamine, and N-acetyl-d-galactosamine were detected. The purified polysaccharides were examined in the RAW264 cell line using antibodies against Toll-like receptors (TLRs) and were found to stimulate TLR4 – a receptor for pathogens – and activate the immune system. These results indicate that polysaccharides in starfish mucus have a positive effect on growth and immunity in fish.
