Por otro lado, la organización de los viajes sin intermediarios a través del uso de Internet, así como el empleo de nuevos dispositivos de acceso a la información hacen que iniciativas como Google Cultural Institute cobren importancia. Para participar en este proyecto transnacional la Junta de Andalucía firmó un contrato de servicios y alojamiento de contenido con la plataforma en 2015. En el presente trabajo, tomamos este documento como estudio de caso para abordar los retos de traducción que planteó un tipo textual de contenido híbrido, jurídico y tecnológico y analizamos la terminología clave a través de un estudio de derecho comparado, lingüístico y traductológico. Con este trabajo pretendemos reconocer los términos clave de este tipo de contrato que es cada vez más habitual en la era digital para la difusión y promoción del turismo cultural. Palabras clave:Google Cultural Institute, digitalización de museos, traducción híbrida, traducción jurídica, contrato de alojamiento web. Abstract Nowadays, cultural tourism is increasing in Andalusia, Spain, which turns out to be very strategic to seasonalization the tourism sector as a whole and raise the economic benefits it produces in this region. At the same time, the organization of trips without intermediaries through the use of the internet and new information access devices makes initiatives such as Google Cultural Institute very relevant. In order to participate in this transnational project, the regional government of Andalusia signed a content hosting and services agreement with this online platform in 2015. In this paper, we take this document as a case study to address the translation challenges posed by a textual type of hybrid content —legal and technological— and analyze its key terminology through a study of compared law and translation. Thus, we intend to recognize the most relevant terms of this type of agreements that is increasingly common in the digital era to disseminate and promote cultural tourism. Key words:Google Cultural Institute, museum digitalization, hybrid translation, legal translation, hosting agreement.
Consideraciones sobre el tratamiento normativo de la entrada y permanencia de animales en establecimientos turísticos en Andalucía
Authors: Alvarez Salcedo Antonio
Published: January 2023

El “turismo con mascotas” en establecimientos petfriendly  es una tendencia emergente y de fuerte desarrollo en los últimos años a la que la oferta turística ha de ir adaptándose para captar a una demanda potencial ciertamente importante. Y es que las mascotas forman parte de la vida de las personas y a muchos viajeros no les gusta dejarlos sólos o en residencias de animales o simplemente no tienen con quien dejarlos cuando hacen turismo. En este trabajo se pretende analizar de manera práctica el tratamiento legal actualmente existente en Andalucía sobre la entrada y permanencia de animales en establecimientos turísticos y espacios públicos tales como medios de transporte, museos y monumentos, todo ello con el objetivo de determinar el nivel de adecuación de la normativa existente a las nuevas tendencias de la demanda turística y el tratamiento de los animales domésticos en cuanto a su tenencia , entrada y permanencia en los establecimientos y espacios referidos.Palabras clave: Turismo con mascotas, establecimientos petfriendly, regulación legal, Andalucía, España.AbstractThis paper analyzes the conceptual differences at the level of tourism management and legal treatment of the different types of private tourist accommodation in houses with a single-family structure in Andalusia, such as the Rural Houses (CR), the tourist lodging in rural áreas (VTAR) and the housing for tourist use in urban areas (VFT) in the case of Andalusia. In recent years there has been an increasingly significant increase in the use of private accommodation for tourism, which has led to the need for a new regulation to regulate this phenomenon linked to tourist rental and that must be clearly differentiated from services and tourist establishments more conventional and typical of the hotel industry as well as the rental of residential housing, in accordance with the provisions of Law 29/1994, of 24 November, on Urban Leases, in whose most recent reform it submits the tourist rental to a specific regime, derived from its sectoral regulations to be developed by the Autonomous Communities.Keywords: Tourism with pets, petfriendly establishments, legal regulation, Andalusia, Spain.

Analysis of the image South Korean university students have of Barcelona before visiting
Authors: ESPINOSA MIRABET SILVIA , KANG SIN GYU
Published: January 2023

The aim of this study is to determine the necessity of measuring the present image of the destinations that are important in tourism marketing and then to provide fundamental material for a marketing strategy parallel to this image. In 2018, 225 thousand Korean tourists arrived in Catalonia, 60% more than in 2017. And since 2012, the number of tourists of this destination has multiplied by 4.5. This tourist flow increases year after year and Barcelona is one of the preferred destinations. Beyond this small context, the truth is that the Catalan tourism industry does not have conscientious studies that describe the image of Barcelona perceived by the Korean tourists. Therefore, statistical data have been analyzed and 340 surveys have been carried out on young Korean people in their twenties who intend to travel to Barcelona. A credibility analysis and a regression analysis were conducted to study the effects of these affective and cognitive images on South Korean students’ intention to visit. As a result of this study, affective image was rejected because it did not have an impact on intention to visit, while cognitive image was found to do influence it.

La crisis sanitaria del Covid-19 ha patentizado la necesidad del sistema hospitalario y sanitario de Europa, en general, y de España, en particular, pero también que puede ser ocasión de crecer y de mejorar, lo que quizás en otras circunstancias desaparece. De esta consideración positiva de la realidad pueden participar y aportar las Humanidades, con su centro de estudio en el patrimonio cultural y su valorización, y, por ende, también generadoras de transferencia, aunque transferencia y gestión siempre sobre la incontestable base del conocimiento y la investigación, pues sin ésta, aquélla es imposible; y transferencia, asimismo, para devolver a la sociedad, a la que servimos, dinamismo y desarrollo social a través del patrimonio cultural, como conocimiento, promoción de empleo, o turismo, rural y urbano, alternativo y creativo, en línea con los trabajos más recientes y punteros al respecto como el de Ortega y Ruiz para la Alpujarra granadina. En ese contexto, este artículo, parte del proyecto de innovación concedido por la UCO para cartografiar y analizar la red benéfico-sanitario asistencial de Córdoba y provincia desde mediados del Setecientos y hasta el presente, para potenciar el turismo cultural desde el patrimonio, pretende trazar sus vectores fundamentales y, por tanto, centrarse en sus objetivos, metodología e historiografía, pues su muy reciente inicio impide aún resultados plenos.

Published: January 2023

In the present study, attempts were made to optimise water spinach (Ipomoea aquatica) in combination with freshwater prawns (Macrobrachium rosenbergii) to be grown under aquaponics culture conditions, especially as an indoor set-up suitable for urban dwellings. A comparison of the morphometric parameters such as linear growth and number of leaves of plants and the survival rate under the soil, aquaponics, aquarium and hydroponics units simultaneously per cycle was done to establish the stability of the system. The water spinach grown under the aquaponics set-up showed significant growth compared to the hydroponics set-up but was less than that of the soil units. Significantly higher growth of freshwater prawns was also recorded in the aquaponics unit compared to the aquarium unit. Though further investigations are still needed to find factors that can give optimum produce, the researchers propose that standardised aquaponic units for water spinach and freshwater prawns can be a safe option for urban households as a sustainable farming practice.

Our study deals with how the short nine-spine stickleback Pungitius kaibarae uses visual cues to select among habitats, thereby reducing predation pressure from the Japanese eel Anguilla japonica. We examined the behaviour of P. kaibaraein selecting four habitats (water  weed, sandy, rocky and open water) under the presence/absence of A. japonica. Using video tracking technology, we found that in the presence of A. japonica, sticklebacks preferred specific refuge patches, such as waterweed and rocks, over open water with a sandy bottom. Thus, our investigation demonstrated the importance of habitat structures in evoking escape behaviour. We discuss the importance of this bold behaviour patterns of the prey fish.Keywords: Bold behaviour, Stickleback, Eel, Swimming speed, Video tracking

Gillnet is the most widely followed selective and passive fishing gear system in all water bodies, especially in the traditionalfishing sector. Many past studies on gillnet fishing in the Vembanad Lake, Kerala, South India focussed on speciesavailability and gear-wise catch of major fishes and showed that there was a significant reduction in the fish catch.Thepresent study used market-based valuation method to estimate economic value generated through gillnet fishing operationin selected village panchayats spreading across three districts viz., Ernakulum, Alappuzha and Kottayam, bordering theVembanad Lake, during the period in 2019-20. The species-wise quantity and value of finfishes and shellfishes caught inthe gillnets from Vembanad Lake, in the three districts were analysed during the survey period. The total number of gillnetfishers living around the Vembanad Lake is about 6157 and the catch was estimated at 4645.97 t of both finfish and shellfishspecies, out of which shrimps formed around 72%. The maximum quantity of catch was observed for catfishes (Arius spp.)at 278.6 t per annum, which fetched a value ₹4.46 crores, followed by Etroplus maculatus at 149 t (₹3.58 crores in valueterms). The economic value generated through gillnet fishing is estimated at ₹57.94 crores.

Luni is an ephemeral and inland saline river flowing through the Thar Desert of India. The present study focusses on the length-weight relationships (LWRs) and condition factor analysis of six native and one invasive alien fish species (Oreochromis mossambicus) collected from the river Luni during the exploratory surveys conducted from October, 2018 to September, 2020. LWRs of native fish species showed negative allometric growth for Aphanius dispar, Cirrhinus mrigalaand Salmostoma bacaila and positive allometric growth for Labeo rohita, Mystus gulio and Systomus sarana. Despite abundant distribution of O. mossambicus in the middle and downstream segments of the river Luni, this study revealed good wellbeing and suitability of this river to native and non-native fish species. This forms the first study that reports the LWRs and Kn value of these fish species from the river Luni, which could be useful for estimating stock characteristics and future evaluation of fish population in this dynamic and fragile ecosystem. Further, results of the present study were also compared with the available literature from nearby and associated ecosystems. The baseline information generated will be helpful in understanding the present status of the fish population and also to carryout ecological studies for their conservation and management in the future.Keywords: Invasive Alien Species, Length-weight relationship, Oreochromis mossambicus, Thar Desert
Native Gold of the Chudnoe Gold–Palladium Deposit (Subpolar Urals, Russia)
Authors: Onishchenko S.A. , Kuznetsov S.K.
Published: January 2023

––The Chudnoe gold–palladium deposit, located within the Central Ural uplift, is confined to the axial zone of an anticlinal structure complicated by faults. Veinlet mineralization is localized in fractured and brecciated Late Riphean–Vendian rhyolites. Native gold and palladium minerals are concentrated mainly in veinlets of Cr-containing muscovite (fuchsite) and, more seldom, at local sites of rhyolite metasomatism, almost free of sulfides. Using a representative material, we studied the composition and texture of native gold and the regularities of their spatial variations. Native gold has composition Au–Ag–Cu and contains Pd and Hg impurities. The proportion of elements varies significantly: The content of Au ranges from 65.8 to 92.7 wt.%, the content of Ag varies from 0.4 to 33.8 wt.%, the content of Cu reaches 12.7 wt.%, and the content of Pd is up to 2.9 wt.%. Gold formed as a homogeneous Au–Ag–Cu solid solution at temperatures above 220 °C. The presence of copper in native gold is probably due to the absence of sulfide ion from the ore-forming hydrothermal solution. With decreasing temperature, Au–Ag–Cu solid solution containing more than 1.1–2.5 wt.% Cu disintegrates into two or three phases, forming characteristic plate–lattice and tabular exsolution textures. In the case of two-phase exsolution, the final phases are Au3Cu and Au–Ag solid solution or AuCu and Au–Ag solid solution; and in the case of three-phase exsolution, these are Au3Cu, AuCu, and Au–Ag solid solution. In some cases, the exsolution was accompanied by the recrystallization of gold with the formation of grain intergrowths. The composition of native gold in the deposit varies significantly, showing a discrete character at different sites of the ore zones, which is consistent with the veinlet ore mineralization. At the final stages of mineral formation, native gold was partly replaced by secondary highfineness gold.
Case Studies and Operation Features of Long Horizontal Wells in Bazhenov Formation

In this study, unique field data analysis and modeling of operating wells with an extended horizontal wellbore (HW) and multistage hydraulic fracturing (MHF) in the Bazhenov formation were conducted. Moreover, a large amount of long horizontal well data obtained from the Bazhenov formation field was used.

Wells with extended HW drilling and MHF are necessary for commercial oil production in the Bazhenov formation. Problems can occur in such wells when operating in the flowing mode and using an artificial lift at low flow rates. This study aimed to describe the field experiences of low-rate wells with extended HWs and MHF and the uniqueness of well operations and complexities. It was also focused on modeling various operation modes of such wells using specialized software and accordingly selecting the optimal downhole parameters and analyzing the sensitivity of fluid properties and well parameters to the well flow.

The flow rates in wells with extended HW and MHF decrease in the first year by 70–80% when oil is produced from ultralow-permeability formations. Drainage occurs in a nonstationary mode in the entire life of a well, leading to complexities in operation. A comprehensive analysis of field data [downhole and wellhead pressure gauges, electric submersible pump (ESP) operation parameters, and phases’ flow rate measurements] and fluid sample laboratory studies was conducted to identify the difficulties in various operating modes. For an accurate description of the physical processes, various approaches were used for the numerical simulation of multiphase flows in a wellbore, considering the change in the inflow from the reservoir. The complexities that may arise during the operation of wells were demonstrated by analyzing the field data and the numerical simulation results. The formation of a slug flow in low flow rates in a wellbore was caused by a rapid decline in the production rate, a decrease in the water cut, and an increase in the gas/oil ratio (GOR) over time. Based on the results, proppant particles can be carried into the HW and thereby reduce the effective section of the well in case of high drawdowns in the initial period of well operation. Consequently, the pressure drops along the wellbore increased, and the drawdown on the formation decreased. Other difficulties were determined to be associated with the consequences and technologies of hydraulic fracturing (HF). These effects were shown based on the field data and the numerical simulation results of the flow processes in wells. In addition, corrective measures were established to address various complexities, and the applications of these recommendations in the field were conducted.

Published: January 2023

Several challenges exist in the application of machine learning (ML) algorithms to reservoir prediction, such as the low accuracy of the reservoir prediction model, long training time, and complicated parameter adjustment. A good optimization algorithm is one of the keys to successfully training an ML model. Therefore, this study focuses on improving the ability of ML models to obtain rich reservoir characteristic information from multicomponent seismic data through an intelligent optimization algorithm and uses this information to predict the oil and gas distribution accurately. Adaptive mutation particle swarm optimization (AMPSO) was used to train the ML models [artificial neural network (ANN) and least-squares support vector machine (LSSVM)] and obtain intelligent prediction models (AMPSO-ANN and AMPSO-LSSVM) for multicomponent seismic reservoir prediction. First, a hyperparameter analysis of the ML models was conducted to determine their structure, and the parameters of the two models were searched globally by AMPSO to obtain an intelligent prediction model for reservoir distribution prediction. The two prediction models were then applied to synthetic reservoir prediction data to confirm their reliability and validity. Finally, they were applied to real data for multicomponent seismic gas reservoir distribution prediction to verify their accuracy. The predictive abilities of the two intelligent models on synthetic and real data sets were compared with those of the unoptimized ANN and support vector machine (SVM) models to verify their validity. The results showed that AMPSO improved the prediction ability of the two models and the prediction accuracy of oil/gas-bearing distribution on the synthetic data and gas-bearing distribution on the real data.
Real-Time Optimization and Decarbonization of Oil and Gas Production Value Chain Enabled by Industry 4.0 Technologies: A Critical Review
Authors: Singh Harpreet , Li Chengxi , Cheng Peng , Wang Xunjie , Hao Ge , Liu Qing
Published: January 2023

The presence of silos in data and technology of the oil and gas (O&G) production value chain prevents the optimal utilization of resources to enhance production, improve efficiency, and reduce carbon emissions in the O&G production value chain. Real-time optimization of O&G production value chain (ROOPVC) can be used to achieve the above-described objectives. Specifically, ROOPVC allows for i) integration of various elements of the O&G production value chain to create a single reference truth of the system, ii) prediction of unified behavior of the single reference truth using physics-based models and data-driven algorithms, and iii) holistic optimization via single unified digital twin (DT).

Based on recent advances, this study reviews system-level and component-level technologies required to implement ROOPVC. Specifically, the study reviews in detail the two major elements of ROOPVC, which are i) DT technology and ii) modeling, simulation, and optimization, respectively. The study also summarizes field experiences in the deployment of ROOPVC. The key challenges, lessons learned, and recommendations for the deployment of ROOPVC are also discussed.

The major findings from this review suggest that ROOPVC i) can enable higher stable production while simultaneously allowing significant carbon savings, ii) is suitable for deployment on a field of any size, and iii) can be deployed quickly due to its modular (microservices) approach.

Advanced oxidation process (AOPs) can be used for the treatment of Harmful Algal Blooms (HABs). In this study, two systems of Fe2+/sodium percarbonate (Fe2+/SPC system) and Fe2+/sodium persulfate (Fe2+/PS system) were established to explore the removal mechanism of Microcystis aeruginosa(M. aeruginosa). The results indicated that the Fe2+/SPC system catalyzed H2O2 to generate a large amount of • OH for oxidation by Fe2+, and formed Fe3+ to promote the flocculation of M. aeruginosa. The persulfate was activated by Fe2+ to generate SO4 •-with super-oxidizing properties, and Fe3+ was generated to realize the oxidation and flocculation of M. aeruginosa in the Fe2+/PS system. Compared with the traditional method in which the pre-oxidation and flocculation processes are carried out separately, the method in this study effectively improves the utilization rate of the flocculant and the removal effect of M. aeruginosa. The absolute value of zeta potential of Fe2+/PS system (|ζ| =0.808 mV) was significantly lower than that of Fe2+/SPC system (|ζ| =21.4 mV)(P < 0.05), which indicated that Fe2+/PS system was more favorable for the flocculation of M. aeruginosa cells than the Fe2+/SPC system.
Sonographically controlled percutaneous A1 pulley release using a new guide instrument – a case series of 106 procedures in 64 patients
Authors: Sutter Damian , Treier Aline , Vögelin Esther
Published: January 2023

With percutaneous pulley release becoming more popular, safety and reliability of the mini-invasive procedure remain a concern. Visualization of the technical steps by ultrasound suggests increased safety but shows the potential for harm to tendons, nerves and vessels without proper instrumentation. We present the results of implementing a sonographically guided percutaneous mini-invasive procedure in 106 trigger digits of 64 patients between 2018–2021. The technique was tested in 16 cadaver hands using a commercially available hook knife. Obvious issues inserting the instrument into the flexor tendon sheath led us to develop a guide instrument, which was modified in due course due to complications early in our series. A revised design of the guide has been in use since November 2019 with improved performance and safety. Complications since instrument revision include two cases of incomplete pulley release and one case of inadvertent skin laceration. The majority of patients report returning to all strenuous activities within two weeks at most apart from four individuals with prolonged postoperative discomfort. In conclusion, the choice of appropriate surgical instruments and practice allows for safe and efficient implementation of a percutaneous procedure in pulley release.
Mapping ethical issues in the use of smart home health technologies to care for older persons: a systematic review
Authors: Felber Nadine Andrea , Tian Yi Jiao (Angelina) , Pageau Félix , Elger Bernice Simone , Wangmo Tenzin
Published: January 2023

Background

The worldwide increase in older persons demands technological solutions to combat the shortage of caregiving and to enable aging in place. Smart home health technologies (SHHTs) are promoted and implemented as a possible solution from an economic and practical perspective. However, ethical considerations are equally important and need to be investigated.

Methods

we conducted a systematic review according to the PRISMA guidelines to investigate if and how ethical questions are discussed in the field of SHHTs in caregiving for older persons.

Results

156 peer-reviewed articles published in English, German and French were retrieved and analyzed across 10 electronic databases. Using narrative analysis, 7 ethical categories were mapped: privacy, autonomy, responsibility, human vs. artificial interactions, trust, ageism and stigma, and other concerns.

Conclusions

The findings of our systematic review show the (lack of) ethical consideration when it comes to the development and implementation of SHHTs for older persons. Our analysis is useful to promote careful ethical consideration when carrying out technology development, research and deployment to care for older persons.

Urban Stream Corridors and Forest Patches – The Connections: A Case Study of Bloomington, IN
Authors: Luchauer Gretchen , Freeman-Day Stephanie , Fischer Burnell
Published: January 2023

Streams and forests are connected ecosystems, but few studies have looked at the connectivity between streams and forests in urban environments. City-made decisions affect connections between streams and forests by isolating both streams and forests. Streams are often channelized or buried to reduce flooding and increase potential developable areas. Forests become fragmented and are removed unless they are protected by public ownership, private ownership, or mixed governance arrangements. Historical choices in land usage affect the sites and sizes of current urban streams, forests, and development. This affects the distribution of impervious surfaces, a ubiquitous urban land cover type, which separates streams from forests. Despite these barriers to stream/forest interactions, cities can experience stream/forest connectivity. Seven Bloomington watersheds are ranked on their proportions of buried streams, channelized streams, forested hydrology, forested streams, urban forest patch cover, and impervious surface cover, along with historical presence of urbanization. Several watersheds demonstrate stream/forest connectivity, with five of these watersheds containing 50% or greater forested stream segments. Bloomington canopy cover reduces stormwater runoff by approximately 127 kiloliters per year. These forested areas reduce flooding, reduce nutrient loading, and reduce stream conditions associated with urban stream syndrome. Streams provide incentive for forest protection, aesthetic value, and recreational value. Understanding urban stream/forest connectivity can improve green infrastructure design and green space design, which improves urban resilience and better connects residents to the environment.

Polyphenols are great interest in recent decades due to the potential health benefits such as protection against development of carcinoma, diabetes, obesity, osteoporosis neurodegenerative and cardiovascular diseases etc. Therefore, researchers and scientists have been more interested in the extraction of polyphenols from plant resources. The present study investigates the microwave-assisted extraction of polyphenols from the Pithecellobium dulce fruit peels. ANOVA pareto analysis and Response surface methodology was employed to analyse the effect of process variables on delignification. Four independent process variables such as microwave irradiation power, microwave irradiation time, pH and Liquid to solid ratio (LSR) were analysed. Microwave-assisted aqueous extraction facilitated in maximum yield of polyphenols from the fruit peels (79.18 mg GAE/g dw). The polyphenol extract exhibited potential antioxidant (IC50 of 63.18 µg/ml) and anticancer (LD50 of 61.3 µg/ml) activity using radical scavenging DPPH and MTT assay respectively. Therefore, our study indicates that the polyphenolics rich, biologically potent Pithecellobium dulce fruit peel extracts can be a good therapeutic and nutraceutical supplement to treat cancer and related complications.

Forests in and around the cities are becoming crucial in climate adaptation as the severity and frequency of heat waves, and urban heat islands are estimated to increase in the coming decades. As the local forestry authority, the forest district manager's role in establishing and managing forested green spaces in and around the cities is essential. The study is based on a land cover analysis, in selected provinces of Türkiye, for a period of three decades. We compared the responses of district forest managers to understand their awareness and perception of urban green areas and related climate change issues. The survey was sent to all district forest managers of the State Forest Service (GDF) and responded to by 69 from 28 provinces. The major land cover maps used were explicitly developed for land cover analysis by the GDF with temporal points of 1990, 2000, and 2015. To calculate the urban forest cover in the city centers, we used the city limit delineation shapefiles produced by the EU Copernicus program. We also employed the land consumption rate/population growth rate metric to reveal and discuss the provinces' land and forest cover changes. The results showed that forest district managers were aware of the general condition of the forests in their provinces. Still, there was a considerable inconsistency between actual land use changes (i.e., deforestation) and their responses. The study also revealed that the forest managers were aware of the increasing influence of climate change issues but were not knowledgeable enough to establish the connection between their tasks and climate change. It has been concluded that the national forestry policy should prioritize the urban-forest interaction and develop the capacities of district forest managers to improve the efficiency of climate policies on a regional scale.

Purpose
To evaluate the differences when performing the sentinel lymph node biopsy (SLNB) before or after neoadjuvant endocrine therapy (NET) in breast cancer patients, and the impact of its timing on prognosis.
Methods
A retrospective cohort study including 91 postmenopausal cases with clinically node-negative and hormone receptor-positive/HER2 negative (HR+/HER2-) breast cancer, treated with NET and SLNB at our institution. SLNB was performed pre-NET until 2014, and post-NET thereafter. Axillary lymph node dissection (ALND) was indicated only in SLNB-macrometastasis, although in selected elderly patients it was omitted. Kaplan-Meier survival curves were obtained in relation to the status of the axilla, and the differences assessed using the log-rank test.
Results
Between December 2006 and March 2022, SLNB was performed pre-NET in 14 cases and post-NET in 77. SLNB-positivity was similar regardless of whether SLNB was performed before or after NET (35.7% and 37%, respectively), with 2/14 SLN macrometastases in the pre-NET cohort and 17/77 in the post-NET cohort. Only three patients (18.7%) with SLN macrometastasis had > 3 positive nodes following axillary node dissection. The 5-year overall survival and distant disease-free survival were 92.4% and 94.8% respectively, with no significant differences according to SLNB status.
Conclusion
SLN positivity did not differ according to its timing (before or after NET). Therefore, NET has no effect on lymph node clearance. Furthermore, the prognosis is good regardless of the axillary involvement. Therefore, factors other than axillary involvement may affect the prognosis in these patients.
Glucocorticoids alleviate particulate matter-induced COX-2 expression and mitochondrial dysfunction through the Bcl-2/GR complex in A549 cells

Exposure to particulate matter (PM) causes mitochondrial dysfunction and lung inflammation. The cyclooxygenase-2 (COX-2) pathway is important for inflammation and mitochondrial function. However, the mechanisms by which glucocorticoid receptors (GRs) suppress COX-2 expression during PM exposure have not been elucidated yet. Hence, we examined the mechanisms underlying the dexamethasone-mediated suppression of the PM-induced COX-2/prostaglandin E2 (PGE2) pathway in A549 cells. The PM-induced increase in COX-2 protein, mRNA, and promoter activity was suppressed by glucocorticoids; this effect of glucocorticoids was antagonized by the GR antagonist RU486. COX-2 induction was correlated with the ability of PM to increase reactive oxygen species (ROS) levels. Consistent with this, antioxidant treatment significantly abolished COX-2 induction, suggesting that ROS is involved in PM-mediated COX-2 induction. We also observed a low mitochondrial membrane potential in PM-treated A549 cells, which was reversed by dexamethasone. Moreover, glucocorticoids significantly enhanced Bcl-2/GR complex formation in PM-treated A549 cells. Glucocorticoids regulate the PM-exposed induction of COX-2 expression and mitochondrial dysfunction and increase the interaction between GR and Bcl-2. These findings suggest that the COX-2/PGE2 pathway and the interaction between GR and Bcl-2 are potential key therapeutic targets for the suppression of inflammation under PM exposure.

The COVID-19 pandemic negatively affected the mental and sexual health of individuals, especially healthcare professionals. In this study, we aimed to investigate the changes in anxiety and sexual activity of male healthcare professionals following vaccination. This prospective cross-sectional and descriptive online survey study was conducted between July 1, 2021 and November 1, 2021, involving a total of 170 healthcare professionals. Socio-demographic characteristics, pre- and post-vaccination anxiety and sexual activity levels of the participants were compared. There was a significant increase in only intercourse times of the participants before and after vaccination (p=0.034). The Beck anxiety scale score decreased from (median: 19, min: 16, max: 47) before vaccination to (median: 17, min: 10, max: 43) after vaccination (p<0.001). Likewise, Arizona Sexual Experiences Scale scores decreased after vaccination (median: 10, min: 5, max: 20) compared to before vaccination (median: 12, min: 5, max: 18) (p<0.001). International Index of Erectile functon(IIEF) score also increased after vaccination (25.49±6.50) compared to before vaccination (24.71±7.10) (p<0.001). Orgasmic Function, Sexual Desire, Intercourse Satisfaction, Overall Satisfaction scores also improved (p=0.013, p<0.001, p=0.027, p<0.001). Mental and Sexual disorders increased with the COVID-19 pandemic. In addition to immunity, the vaccine also has positive effects on anxiety and sexual activity.
