Evaluating the Transferability of Spectral Variables and Prediction Models for Mapping Forest Aboveground Biomass Using Transfer Learning Methods
Authors: Chen Li , Lin Hui , Long Jiangping , Liu Zhaohua , Yang Peisong , Zhang Tingchen
Published: November 2023

Forests, commonly viewed as the Earth’s lungs, play a crucial role in mitigating greenhouse gas emissions, regulating the globe, and maintaining ecological equilibrium. The assessment of aboveground biomass (AGB) serves as a pivotal indicator for evaluating forest quality. By integrating remote sensing images with a small number of ground-measured samples to map, forest AGBs can significantly reduce time and labor costs. Current research mainly focuses on improving the accuracy of mapping forest AGBs, such as integrating multiple-sensors remote sensing data and models. However, due to uncertainties associated with remote sensing images and complexities inherent in forest structures, the accuracy of mapping forest AGBs is constrained by both the quantity and distribution of ground samples available. The development of transfer learning methods can fully utilize ground-based measurement data and enable the application of samples across regions and time. To evaluate the potential of transfer learning methods in mapping forest AGBs, this study conducted a spatial–temporal transfer of spectral variables (SVs) and prediction models (PMs) using a direct-push transfer method, and a new evaluation metric, relative change of R-squared (RCRS), was proposed to assess the transferability of SVs and PMs. The results showed that the transferability of SVs and PMs in the spatial target domain is obviously greater than that in the temporal target domain. Compared to the temporal target domain, the RCRS for transfer SVs in the spatial target domain was lower by 20.89 (oak) and 20.88 (Chinese fir) and for transfer PMs by 24.16 (oak) and 24.79 (Chinese fir). Tree species is also one of the main factors affecting the spatial and temporal transfer of SVs, and it is challenging to transfer SVs between different tree species. The results also show that nonparametric models have better generalization performance, and their transferability is much greater than that of parametric models.
A Review of Root Zone Soil Moisture Estimation Methods Based on Remote Sensing
Authors: Li Ming , Sun Hongquan , Zhao Ruxin
Published: November 2023

Root zone soil moisture (RZSM) controls vegetation transpiration and hydraulic distribution processes and plays a key role in energy and water exchange between land surface and atmosphere; hence, accurate estimation of RZSM is crucial for agricultural irrigation management practices. Traditional methods to measure soil moisture at stations are laborious and spatially uneven, making it difficult to obtain soil moisture data on a large scale. Remote sensing techniques can provide soil moisture in a large-scale range, but they can only provide surface soil moisture (SSM) with a depth of approximately 5–10 cm. In order to obtain a large range of soil moisture for deeper soil layers, especially the crop root zone with a depth of about 100–200 cm, numerous methods based on remote sensing inversion have been proposed. This paper analyzes and summarizes the research progress of remote sensing-based RZSM estimation methods in the past few decades and classifies these methods into four categories: empirical methods, semi-empirical methods, physics-based methods, and machine learning methods. Then, the advantages and disadvantages of various methods are outlined. Additionally an outlook on the future development of RZSM estimation methods is made and discussed.

Published: November 2023

The European Space Agency (ESA) developed the Sentinel-2 Multispectral Imager (MSI), which offers a higher spatial resolution and shorter repeat coverage, making it an important source for the remote-sensing monitoring of water bodies. Atmospheric correction is crucial for the monitoring of water quality. To compare the applicability of seven publicly available atmospheric correction processors (ACOLITE, C2RCC, C2XC, iCOR, POLYMER, SeaDAS, and Sen2Cor), we chose complex and diverse lakes in Qinghai Province, China, as the research area. The lakes were divided into three types based on the waveform characteristics of Rrs: turbid water bodies (class I lakes) represented by the Dabusun Lake (DBX), clean water bodies (class II lakes) represented by the Qinghai Lake (QHH), and relatively clean water bodies (class III lakes) represented by the Longyangxia Reservoir (LYX). Compared with the in situ Rrs, it was found that for the DBX, the Sen2Cor processor performed best. The POLYMER processor exhibited a good performance in the QHH. The C2XC processor performed well with the LYX. Using the Sen2Cor, POLYMER, and C2XC processors for classes I, II, and III, respectively, compared with the Sentinel-3 OLCI Level-2 Water Full Resolution (L2-WFR) products, it was found that the estimated Rrs from the POLYMER had the highest consistency. Slight deviations were observed in the estimation results for both the Sen2Cor and C2XC.
RETRACTED: An Exploratory Study of the Intrinsic Mechanisms of Occupational Stigma Consciousness, Career Development, and Work–Life Balance among Female Leaders
Authors: Lai Qiujia , Lee Gukseong
Published: November 2023

This study suggests a research model for investigating the negative impact of occupational stigma consciousness from the perspective of the Conservation of Resources theory. It explores the intrinsic mechanisms connecting female leaders’ stigma consciousness with their career development and work–life balance and verifies the relationships between these variables. This study conducts a quantitative analysis of data collected from a sample of 400 female leaders in Chinese enterprises and institutions. A structural equation modeling approach is used to test the proposed hypotheses. Our findings reveal that the stigma consciousness of female leadership has a significant negative impact on their career advancement and work–life balance. This negative influence is mediated by emotional exhaustion. Additionally, self-efficacy negatively moderates the relationship between female leadership stigma consciousness and emotional exhaustion.
Innovative Dual-Stage Blind Noise Reduction in Real-World Images Using Multi-Scale Convolutions and Dual Attention Mechanisms
Authors: Rahman Ziaur , Aamir Muhammad , Bhutto Jameel Ahmed , Hu Zhihua , Guan Yurong
Published: November 2023

The distribution of real noise in images can disrupt the inherent symmetry present in many natural visuals, thus making its effective removal a paramount challenge. However, traditional denoising methods often require tedious manual parameter tuning, and a significant portion of deep learning-driven techniques have proven inadequate for real noise. Moreover, the efficiency of end-to-end algorithms in restoring symmetrical patterns in noisy images remains questionable. To harness the principles of symmetry for improved denoising, we introduce a dual deep learning model with a focus on preserving and leveraging symmetrical patterns in real images. Our methodology operates in two stages. In the first, we estimate the noise level using a four-layer neural network, thereby aiming to capture the underlying symmetrical structures of the original image. To enhance the extraction of symmetrical features and overall network performance, a dual attention mechanism is employed before the final convolutional layer. This innovative module adaptively assigns weights to features across different channels, thus emphasizing symmetry-preserving elements. The subsequent phase is devoted to non-blind denoising. It integrates the estimated noise level and the original image, thus targeting the challenge of denoising while preserving symmetrical patterns. Here, a multi-scale architecture is used, thereby amalgamating image features into two branches. The first branch taps into dilation convolution, thus amplifying the receptive field without introducing new parameters and making it particularly adept at capturing broad symmetrical structures. In contrast, the second branch employs a standard convolutional layer to focus on finer symmetrical details. By harnessing varied receptive fields, our method can recognize and restore image symmetries across different scales. Crucial skip connections are embedded within this multi-scale setup, thus ensuring that symmetrical image data is retained as the network deepens. Experimental evaluations, conducted on four benchmark training sets and 12 test datasets, juxtaposed with over 20 contemporary models based on the peak signal-to-noise ratio (PSNR) and structural similarity (SSIM) metrics, underscore our model’s prowess in not only denoising but also in preserving and accentuating symmetrical elements, thereby setting a new gold standard in the field.
Knowledge about Snake Venoms and Toxins from Colombia: A Systematic Review
Authors: Pereañez Jaime Andrés , Preciado Lina María , Rey-Suárez Paola
Published: November 2023

Colombia encompasses three mountain ranges that divide the country into five natural regions: Andes, Pacific, Caribbean, Amazon, and Orinoquia. These regions offer an impressive range of climates, altitudes, and landscapes, which lead to a high snake biodiversity. Of the almost 300 snake species reported in Colombia, nearly 50 are categorized as venomous. This high diversity of species contrasts with the small number of studies to characterize their venom compositions and natural history in the different ecoregions. This work reviews the available information about the venom composition, isolated toxins, and potential applications of snake species found in Colombia. Data compilation was conducted according to the PRISMA guidelines, and the systematic literature search was carried out in Pubmed/MEDLINE. Venom proteomes from nine Viperidae and three Elapidae species have been described using quantitative analytical strategies. In addition, venoms of three Colubridae species have been studied. Bioactivities reported for some of the venoms or isolated components—such as antibacterial, cytotoxicity on tumoral cell lines, and antiplasmodial properties—may be of interest to develop potential applications. Overall, this review indicates that, despite recent progress in the characterization of venoms from several Colombian snakes, it is necessary to perform further studies on the many species whose venoms remain essentially unexplored, especially those of the poorly known genus Micrurus.
Repulsive Aftereffects of Visual Space
Authors: Zimmermann Eckart
Published: November 2023

Prolonged exposure to a sensory stimulus induces perceptual adaptation aftereffects. Traditionally, aftereffects are known to change the appearance of stimulus features, like contrast, color, or shape. However, shifts in the spatial position of objects have also been observed to follow adaptation. Here, I demonstrate that visual adaptation produced by different adapter stimuli generates a bi-directional spatial repulsion. Observers had to judge the distance between a probe dot pair presented in the adapted region and compare them to a reference dot pair presented in a region not affected by adaptation. If the probe dot pair was present inside the adapted area, observers underestimated the distance. If, however, the dot pair straddled the adapted area, the distance was perceived as larger with a stronger distance expansion than compression. Bi-directional spatial repulsion was found with a similar magnitude for size and density adapters. Localization estimates with mouse pointing revealed that adaptation also affected absolute position judgments. Bi-directional spatial repulsion is most likely produced by the lines of adapter stimuli since single bars used as adapters were sufficient to induce spatial repulsion. Spatial repulsion was stronger for stimuli presented in the periphery. This finding explains why distance expansion is stronger than distance compression.

The Visual Trademark of the Greek Novel. Novelistic Opening Ekphraseis in Chariton and Heliodorus
Authors: Lefteratou Anna
Published: November 2023

In this analysis I examine the relationship of the Greek novel with the imperial and late antique visual culture. The novel’s ekphrastic opening scenes prompt the reader to recall particular works of art, well embedded in his/ her ‘ Gallery of the Mind’. In my analysis I compare Chariton’s description of Callirhoe’s Scheintod, which dominates the first volume of the novel, with the archetype of the Sleeping Ariadne, and I suggest an influence of the visual milieu on the novel but also vice versa. In the second part of the paper I study the opening of Heliodorus’ Aethiopica, specifically Chariclea embracing Theagenes, in relation to the archetype of the Magna Mater lugens embracing her acolyte. My aim is to show that, unlike Chariton, Heliodorus follows a more complex syncretic aesthetics typical of Late Antiquity. My conclusions address the programmatic role of ekphrastic openings in the genre and explore the shift in visual taste from imperial to late antique times.
Hanarrus, magistratus de la cité des Consoranni
Authors: Arbabe Emmanuel
Published: November 2023

Hanarrus, magistratus of the City of Consoranni – A funerary inscription made in honor of a Consorannus (CIL XIII, 5), which we shall place at the beginning of the Julio-Claudian period, shows that he was quaestor and mag() among his people. The study of this inscription – made a short time after the Augustan reforms – as well as the concurrent institutional situations in the Treveri and Helvete cities, reinforce the idea that Hanarrus was a magistrate of the city of Consoranni and not the magister of a pagus of the city of the Convenae, as was predominantly stated. We can also show that in Gaul, as elsewhere, the term mag(), when it appears alone, should be expanded to magistratus rather than to magister or magister pagi, and that the term designates the highest municipal magistrate.
Chrysostom, Ammianus, and the Death of the Empress Eusebia
Authors: Woods David
Published: November 2023

A homily by John Chrysostom recording the misfortunes suffered by a succession of emperors, beginning with Constantine I, includes a description of the death of Eusebia, the second wife of Constantius II, as a result of treatment for infertility, where the woman responsible for this treatment is said to have destroyed herself also, by which is presumably meant that she was executed for her apparent role in the empress’ death. It is argued that this description of the death of Eusebia deserves to be taken seriously, and that the prime candidate for identification as the woman held responsible for her death is Assyria, the wife of the magister peditum Barbatio, who was executed alongside him in 359. Ammianus seems to have deliberately concealed this aspect of the execution of Barbatio and Assyria in order to pursue a particular characterization of Barbatio’s death as being the result of the same sort of vicious but baseless rumors that he had himself used against his rivals up to this point.

Değişen ve gelişen yaşam şartları sebebiyle insanların üretim ve tüketim biçimleri de değişmektedir. Bu değişim, bazı kültürel değerlerin kaybolmasına ve yerine yeni unsurların alınmasına sebep olmaktadır. Teknolojik gelişmeler sebebiyle kaybolan kültürel değerlerden biri de geleneksel mesleklerdir. Geleneksel meslekler, insan gücüne duyulan ihtiyacın azalması ve modern insanın taleplerinin değişmesiyle yok olmaktadır. Bu çalışmada gelişen teknolojinin gerisinde kalarak el emeğiyle üretim yapılan, üretildiği bölge olan Gaziantep’in kültürel mirası içinde değerlendirilen ve günümüzde yeteri kadar ustası bulunamadığı için artık kaybolan kuşakçılık mesleğinin tanıtılması, korunması ve gelecek nesillere aktarılması amaçlanmaktadır. Bu amaç doğrultusunda Gaziantep’teki son kuşak ustalarına ve konu hakkında bilgi sahibi olan kaynak kişilere ulaşılmış ve çalışmanın temel verileri bu kişilerle yapılan görüşmeler ve gözlem yoluyla elde edilmiştir. Bu verilerle kuşakçılık mesleğinin tarihi ve kökeni, Gaziantep’teki kuşak ustaları, kuşak üretiminin tekniği ve üretiminde kullanılan malzemelerin özellikleri, kuşağın kullanım alanları, mesleğin geçmişten günümüze geçirdiği değişimler ve kuşakçılık etrafında oluşan kültürel varlık hakkındaki bilgiler derlenmiştir. Buna göre; kuşakların, yaşam biçimlerinin farklılaşması ve insan ihtiyaçlarının değişmesiyle birlikte günlük yaşamdaki önemini kaybettiği, günümüzde bazı bölgelerde nadiren de olsa kullanım özelliğini korumakla birlikte genellikle halk oyunları kostümlerinde ve geleneksel üretim amacının dışında çanta, cüzdan, şapka gibi süs eşyalarının yapımında ve çeşitli mekânlarda dekor olarak kullanıldığı görülmüştür. Temsil ve sunum özellikleri değişmiş olan kuşağın hâlâ üretim yapan son iki ustası da meslekten çekildiğinde kuşakçılık artık kaybolmuş bir geleneksel meslek olacaktır.

Published: November 2023

Há décadas se reconhece que a depressão é uma doença global, cujos sintomas trazem várias consequências negativas e incapacitantes para as pessoas e a sociedade como um todo. Todavia, a ansiedade, a depressão e o estresse entre estudantes do curso de Medicina tem sido uma condição cada vez mais prevalente, que se tornou foco de atenção e motivo de preocupação entre os especialistas da área de saúde. O ensino médico expõe os acadêmicos a cargas de exigência, tornando-os potencialmente vulneráveis a distúrbios emocionais, ou seja, torna a faculdade de medicina um ambiente hostil e temido por parte dos estudantes, principalmente os que já tem algum gatilho pessoal e/ou familiar de quadros depressivos (JUNIOR, 2022). Diante disso, este estudo teve como objetivo identificar possíveis suspeitas de depressão entre estudantes de Medicina de um Centro Universitário no Interior do Estado de São Paulo. Trata-se de um estudo transversal, com abordagem quantitativa do tipo levantamento de dados. Todos os alunos de cada semestre letivo do curso de medicina foram convidados a participar do estudo, sendo que 150 pessoas aceitaram preencher o formulário. O levantamento quantitativo de sintomas depressivos na comunidade acadêmica foi coletado por meio de aplicação de um questionário disponibilizado na plataforma Google Forms. O questionário contou com um instrumento de rastreamento de sintomas depressivos chamado Inventário de Beck de depressão (BDI - II). Ao final, os dados foram analisados por meio de técnicas de análise descritiva como tabelas dinâmicas e gráficos. Os resultados encontrados foram comparados entre si usando as variáveis sexo, idade, semestre letivo, sintomas mais prevalentes e menos prevalentes. Os resultados obtidos indicam que o Centro Universitário pesquisado apresentou uma expressiva maioria de pessoas com nenhum ou mínimos sintomas de depressão em relação às que apresentam algum indício de sintoma depressivo (leve, moderado e severo). Esse fato é de extrema relevante, pois mostra que o ensino médico na universidade estudada demonstra um equilíbrio entre a cobrança acadêmica e as condições psicológicas de seus universitários.

At present, there are a significant number of research results devoted to the study of various types of degradation processes occurring in technical elements and systems. In most works, each of the processes is analyzed separately, and taking into account their influence on the re-sidual life of the product is reduced to choosing and taking into account the dominant process – the most intensively developing process, representing a so-called «weak link» in the theory of reliability. This approach greatly simplifies the degradation pattern of the product, which leads to overestimated prediction results that are unacceptable in critical application systems. The article proposes a method that in an accessible engineering form allows for calculating the re-sidual resource of objects that are subject to the simultaneous influence of several degradation processes with different partial participation. The method is based on the calculation of the av-erage rate and the coefficient of variation of the generalized degradation process. The calcula-tions are carried out using a probabilistic-physical approach which includes a probabilistic model of a diffusion-monotonous distribution of failures (DM-distribution). This distribution is specially formalized on the basis of a Markov random process of diffuse type with a constant rate. The diffusion-monotonic distribution most accurately aligns the statistical data on failures of mechanical objects. Under the influence of several degradation processes, the normalization of initial data and information on the share participation of each of the constituent degradation processes in the generalized degradation process was used for the first time. The method makes it possible to refine the estimate of the product's residual life in comparison with the estimate obtained by taking into account only one dominant degradation process. The obtained refined estimate of the residual life allows for reducing operating costs by optimizing the overhaul in-tervals and establishing the actual life of the objects under study.

The attributive model of dependable software (AMDS) is designed by analogy with the attributive model for dependable computer systems (CS) and expanded with special attributes and metrics according to the ДСТУ ISO/IEC 25051:2016 Systems and software engineering. Requirements for the quality of systems and software tools and their evaluation (SQuaRE). Requirements for the quality of ready-to-use software product (RUSP) and instructions for its testing (ISO/IEC 25051:2014, IDT). The main attributes of the model have been defined. These are functional suitability, performance level, compatibility, availability of use, reliability, security, ease of support, mobility, efficiency, productivity, satisfaction, the lack of risks, coverage, redundancy, and self-control. An object-independent multipurpose approach to the evaluation of software attributes and metrics has been developed. The comprehensive assessment of software dependability is carried out using AMDS in the form of a linear functional containing estimates of all attributes of the model. A quantitative assessment of the level of software dependability has been considered using the example of the Laboratory Information System (LIS) which automates the work of medical la-boratories. The given example of the software has an overall rating that, according to the rating scale, has a satisfactory level of dependability. The attributive model of dependable software and the assessment of dependability levels can be used by specialists in the field of system de-pendability in various fields of application.
Information security of corporate databases

Published: November 2023

Every day, companies all over the world collect and generate a large amount of data. Now in-formation is digital and is stored in automated digital databases, the use of which allows for processing large amounts of data that previously were difficult to process. Protecting corporate databases and the information within them is essential for economic security. It includes their physical protection, productivity assurance and monitoring, data protection from destruction or damage, access control, and recording of new databases appearing in the infrastructure. Howev-er, since users of different types and levels of access (internal users, system administrators, contractors, partners, and M2M communications) have access to databases, they can abuse their access rights in several ways. These may be an abuse of excessive, objectively necessary, or non-used rights. As a rule, an inefficiently controlled process of granting access rights creates excessive access rights which in turn may cause new information security risks. Security measures include implementing an access management process, granting minimally necessary access rights, and implementing a mechanism to control and block the given access rights. This article discusses such threats to databases as SQL Injections and NoSQL injection attacks, in-sufficient detailing of events in databases, backup leaks, vulnerabilities and configurations, DDoS attacks, and methods to counter these threats. The most effective way to protect data-bases is to implement specialized software and hardware complexes such as Imperva DBS and Imperva WAF developed for database protection. The use of Imperva DBS will help to solve all the key tasks of database protection and provide complete visibility and control over their usage in the enterprise infrastructure.

Quick and accurate provision of information in the processes of situational management ac-quires special importance in the critical areas of application – the prevention and elimination of the consequences of catastrophic events, the management of military operations, medical activi-ties, the management of energy systems, etc. The goals and objectives of activities in these are-as also determine the specifics of building appropriate situation management systems for them. The functioning of such systems is based on obtaining accurate and current information about the environment in which situational management is carried out. The convergence of situation management systems with the means of wireless sensor networks (Wireless Sensor Networks, WSN) and the Internet of Things (IoT) ensures obtaining such information. The article analyzes the means of the Internet of Things from the point of view of their ability to be combined in sit-uation management systems to solve management problems in various spheres of activity. The construction features and advantages of using situational systems based on IoT in various spheres of activity are considered. The convergence of IoT in situational systems of various types requires the solution of IoT-typical tasks related to the organization of a heterogeneous network environment with controlled energy consumption and the need to process large vol-umes of data. The paper demonstrates that the scope of application determines the specific re-quirements for the construction of situation management systems, and in each specific case the system of requirements is focused on the support of a critical requirement. One of the main problems of the convergence of IoT and situation management systems is the difficulty of standardizing the operating environment. The multiplicity and variety of options for possible solutions in the development of such systems determine the need for the use of intelligent tech-nologies for the development of systems with the use of artificial intelligence and knowledge models of the target subject area.

Published: November 2023

The article is dedicated to the analysis of data protection issues, particularly personal data, in medical institutions of various ownership forms. The necessity of implementing comprehensive data security systems is justified by the Bell-LaPadula model, which is considered a foundation for the development of a complex data security system within the enterprise. The Bell-LaPadula model represents an access control system based on a hierarchical data access structure. How-ever, using a rigid hierarchical approach when building an information infrastructure of an en-terprise based on this model, taking into account different levels of information confidentiality, might not account for the possibility of insider intervention at higher levels. The article analyz-es the key aspects of this model, including assigning special security levels to all participants in data processing and to documents containing the protected data. To ensure security and access regulation based on an adapted model, individual access levels that correspond to each user’s responsibilities and confidentiality level are proposed for them. After implementing a compre-hensive system for protecting confidential data and assigning special security levels to all par-ticipants in the processing of protected data and documents, a clear differentiation of ownership rights to information of different values emerged. This facilitates further expansion of the circle of employees with access to this information, reduces access time, and forms informational and analytical reports on access control system performance. The use of the hierarchical Bell-LaPadula access model allows for effective control over access to the information system and ensures overall enterprise security.

Published: November 2023

In direct digital control (DDC) systems, computers replace traditional analog control devices. Direct digital control systems not only more efficiently perform the functions carried out by analog control devices but also provide new opportunities for increasing control flexibility, such as reprogramming to achieve the required control effects. The principles of developing di-rect digital control systems are described using the example of systems for regulating the tech-nological parameters of rolling. Both analog and discrete automatic control systems (ACS) are used to control mechanisms and equipment at the lower level of the integrated automated con-trol system (IACS) as well as to regulate the technological parameters of rolling. Direct digital control systems built on microprocessor computing technology are widely used. This is basic automation. With traditional control carried out using local automation tools at the lower level of the IACS, each executive mechanism is associated with a separate local system. In a DDC system, a computer operating in a multiplexed time-sharing mode simultaneously regulates several control loops. The computer works on the principle of step-by-step control with a short-term sequential connection to each of the serviced control circuits. It calculates and provides each control loop with new control input values. The main advantages of using DDC systems are listed in the paper. Some algorithms for direct digital control on heavy plate rolling mills and the structure of the algorithm and software of DDC are provided in the article. Some solu-tions regarding the development of DDC systems used for the creation of technological process automation systems at rolling mills are also described.

This cross-sectional study assessed the possible correlation between OIL and the functional parameters of sperm cells. Methods. In 229 volunteers, oral rinse and semen samples were assessed for oPMN, semen polymorphonuclears (sPMNs), sperm concentration, total sperm count, motility, morphology, and sperm DNA fragmentation index (SDFi). A multiple linear regression model was conducted to evaluate the relationships between oPMN and semen parameters. Results. The effect of elevated oPMN counts on total motility rate, progressive rate, and percentage of sperm cells with normal morphology was significant (P<0.001), with an inverse relationship, i.e., with every unit increase in oPMN count, the mentioned parameters would decline by 0.573, 0.367, and 0.407 units, respectively. oPMN counts also correlated positively with sPMN counts and SDFi (P<0.001), i.e., with every unit increase in the oPMN measures, sPMN counts would increase by 0.126 million/mL, with an 0.733% increase in SDFi. However, there was no significant association between oPMN counts and sperm concentration. Conclusion. OIL, as represented by oPMN counts, might affect male fertility as there is a positive correlation between the levels of these inflammatory cells and decreased sperm motility, abnormal morphological changes, increased sPMN counts, and increased SDFi.

Background. Dental erosion is the loss of dental hard tissues through the acid dissolution of tooth minerals. One of the major factors that cause erosion is the consumption of acidic food and drinks. This study investigated and compared the effect of vitamin waters, herbal beverages, carbonated soft drinks, and fruit juices on the loss of human dental hard tissue. Methods. Human tooth samples were immersed in various drinks: vitamin waters, herbal beverages, carbonated soft drinks, and fruit juices. The pH value of each drink was measured using a pH meter. The weight of each sample was determined before and after six days of immersion in the tested drink, and the weight loss percentage was calculated. The exposed tooth surfaces were also examined under a scanning electron microscope. Results. Most of the tested drinks were acidic and displayed pH values lower than the critical pH for enamel erosion. Significant weight loss of the tooth samples was found in all tested drink groups. Additionally, the samples immersed in fruit juices and herbal beverages exhibited significantly greater weight loss than those immersed in carbonated soft drinks. Scanning electron micrographs showed samples immersed in the tested drinks to demonstrate structural disintegration with occasional void spaces, except for samples immersed in Doi Kham® Lemongrass drink. Conclusion. Most of the tested drinks have the potential to cause dissolution and destruction of dental hard tissues. Consumers should be aware that prolonged exposure to these drinks could lead to permanent loss of tooth mineral and dental erosion.

Background. There is no standard protocol for immediate implant placement and subsequent loading in the smile zone. We aimed to evaluate the long-term outcomes of simultaneous implant placement, soft tissue grafting, and immediate prosthetic loading in the esthetic zone. Methods. Thirty-five implants were placed in the maxillary aesthetic zone. Twenty-two patients were evaluated using the Pink Esthetic Score (PES) and White Esthetic Score (WES). Also, the degree of peri-implant bone resorption and patient survey were applied for the esthetic and functional outcomes. Results. The esthetic and harmonizing outcomes were achieved according to the mean total PES/WES value (17.9±2.0). The mean overall PES was 8.5±1.66. The papilla level had the highest mean score (1.8±0.36). Furthermore, the combination of root convexity/color and soft tissue color and texture was one of the key values in evaluating the effectiveness of this method (the mean value was 1.5±0.5). The mesial and distal papillae were 1.6±0.5 and 1.8±0.4, respectively. None of the 35 implants reached below 6 points (which is considered an esthetically unsatisfactory result). The mean WES score was 9.5±0.57. The average degree of total peri-implant bone resorption was 1.05±0.3 mm after 12 months. According to the questionnaire, all the patients smiled without hesitation and were satisfied with the treatment (100%). Conclusion. This study showed that restoring one or more teeth in the smile zone using the concept of one-stage implant placement, soft tissue flap augmentation, and loading with provisional crowns was an esthetically successful and predictable method.

Introduction: This study investigated the paracrine therapeutic effects of intra-tracheal administration of bone marrow-derived c-Kit+and c-Kit- cells on the T helper (Th)1/Th2 balance in ovalbumin-induced acute asthma in male rats. Methods: Forty male Wistar rats were randomly allocated into four experimental groups; healthy (group C) and sensitized (group S) rats received PBS (Phosphate-buffered saline); sensitized rats received PBS containing c-Kit- (group S+c-Kit- ) and c-Kit+cells (group S+c-Kit+). Total and percentages of differential leukocytes were calculated in bronchoalveolar Lavage. The lung cellular contents of interleukin (IL)-4, IL-10, and interferon gamma (IFN-γ) mRNAs were measured quantitatively. Moreover, the existence of excessive collagen deposition in pulmonary interstitial space was evaluated through Masson’s trichrome staining. Results: The results showed the successful homing of c-Kit+cells into the asthmatic niche. The significantly increased total number of leukocyte, eosinophil, neutrophil, and IL-4 mRNA levels, as well as decreased lymphocyte count, IL-10, IFN-γ mRNAs, and IL-4/IFN-γ ratio, were observed in asthmatic rats compared to C group (P<0.001). C-Kit+cells, but not c-Kit- cells, had the potential to participate in these changes (P<0.001 to P<0.05). The deposition of collagen fibers in the asthmatic pulmonary tissue decreased after administration of both c-Kit+and c-Kit-cells, which were more prominent in the S+c-Kit+group. Conclusions: The results of the current experiment highlighted the therapeutic capacity of c-Kit+cells in the alleviation of asthmatic changes at the cellular level.

As enzimas estão entre os principais alvos de pesquisas biotecnológicas pelo seu importante papel nos mecanismos celulares e aplicações em processos industriais. O objetivo do estudo foi selecionar linhagens de fungos, isoladas de larvas de Simuliidae, produtoras das enzimas amilase e celulase em meio de cultura sólido. Foram utilizadas 37 linhagens fúngicas cultivadas e armazenadas no INPA. Para o crescimento das diferentes linhagens fúngicas e indução das enzimas foi utilizada solução de Manachini, suplementada de substrato indutor. O cultivo das linhagens foi realizado com inóculo direto de 5x106 esporos/mL, mantidos sob agitação a 140 rpm em temperatura ambiente durante 72 horas. Ao término do período de incubação, as culturas foram filtradas e, em seguida foram adicionados 50µL do filtrado em meio de cultura sólido pela técnica de “Cup plate”. As placas foram envolvidas em papel alumínio e incubadas a 37º C durante 72 horas. Foram utilizadas soluções reveladoras de atividade enzimática, iodo 0,1 Mol/L e solução de vermelho congo a 0,1%), para amilases e celulases, respectivamente. A atividade enzimática foi detectada pelo diâmetro do halo. Do total de 37 linhagens analisadas, 60% apresentaram degradação de substrato tanto para amilase como para celulase e 40% não apresentaram atividade para estas enzimas. As espécies com maior nível de degradação do substrato foram Aspergillus japonicus Saito (halo= 7mm, celulase) e Trichoderma harzianum Rifai (halo= 5mm, amilase). Constata-se assim o potencial desses microrganismos para aplicação industrial, criando novas oportunidades para o desenvolvimento do mercado de enzimas na Amazônia.
