Le système d’élevage pastoral est critiqué pour son impact environnemental en raison des fortes émissions de gaz à effet de serre par unité de produit et l’effet néfaste sur le sol et la végétation. Au Sénégal, le stock de carbone dans la végétation est suivi par le Centre de suivi écologique dans 24 sites du Sahel depuis 1987. Toutefois, le stock de C du sol, paramètre essentiel aux processus d’humification de la litière des arbres et de rhizodéposition des herbacées, n’est pas pris en compte. Cette étude visait à déterminer l’influence de l’arbre et des facteurs environnementaux sur les teneurs en C du sol. Ainsi, 15 sites de suivi du Centre ont été sélectionnés, et 480 échantillons de sol ont été prélevés à 0–10 cm et 10–30 cm de profondeur sous et hors houppier. Les teneurs en C et en N totales ont été prédites par spectroscopie proche infrarouge (SPIR) et les stocks de C et de N calculés à partir de 60 échantillons de sol prélevés sous et hors houppier. Une analyse en composantes principales a permis d’identifier les facteurs impliqués dans la variation des stocks de C. Ainsi, dans la zone sylvopastorale du Sénégal, ces stocks ont varié le long d’un gradient nord-sud ; ils ont été positivement corrélés à la pluviométrie, au taux de couverture arborée et à la biomasse. Ils ont varié entre 9,3 et 29,7 Mg C/ha à 10–30 cm. A une échelle plus fine, l’arbre a induit une augmentation des teneurs en C et en N sous houppier dans l’horizon 0–10 cm. Cette étude a montré que les stocks de C du sol peuvent servir à déterminer les besoins de compensation des émissions de C dans le Sahel à travers la plantation d’arbres.

Published: September 2022

Transthyretin (TTR)-related amyloidosis (ATTR) is a heterogeneous disease with different organ involvement depending on the type of TTR infiltration [mutated (vTTR) or wild-type (wtTTR)]. Genetic testing in ATTR is required to define diagnosis and identify asymptomatic at-risk family members. Since new therapies are maximally effective in the early stages of the disease, there is a growing agreement about the need for close monitoring of genotype-positive, phenotype-negative individuals to assure a prompt treatment when minor disease signs are detected. This review summarizes the complexity of genotype-phenotype correlation and revises the current indications with respect to familiar screening and management of asymptomatic carriers.
Extracellular vesicles in reproduction and pregnancy
Authors: Smith Tahlia I. , Russell Ashley E.
Published: September 2022

Extracellular vesicles (EVs) are small, lipid-bound packages that are secreted by all cell types and have been implicated in many diseases, such as cancer and neurodegenerative disorders. Though limited, an exciting new area of EV research focuses on their role in the reproductive system and pregnancy. In males, EVs have been implicated in sperm production and maturation. In females, EVs play a vital role in maintaining reproductive organ homeostasis and pregnancy, including the regulation of folliculogenesis, ovulation, and embryo implantation. During the development and maintenance of a pregnancy, the placenta is the main form of communication between the mother and the developing fetus. To support the developing fetus, the placenta will act as numerous vital organs until birth, and release EVs into the maternal and fetal bloodstream. EVs play an important role in cell-to-cell communication and may mediate the pathophysiology of pregnancy-related disorders such as preeclampsia, gestational diabetes mellitus, preterm birth, and intrauterine growth restriction, and potentially serve as noninvasive biomarkers for these conditions. In addition, EVs may also mediate processes involved in both male and female infertility. Together, the EVs secreted by both the male and female reproductive tracts work to promote reproductive fertility and play vital roles in mediating maternal-fetal crosstalk and pregnancy maintenance.
Satellite sensors as an emerging technique for monitoring macro- and microplastics in aquatic ecosystems
Authors: Mukonza Sabastian Simbarashe , Chiang Jie-Lun
Published: September 2022

Plastic pollution in aquatic ecosystems has been identified as a growing global water pollution threat that is negatively impacting water quality and, as a result, affecting the health of humans, aquatic animals, and wildlife. Therefore, it presents a global environmental catastrophe that requires immediate attention. Plastics in water (in their different forms, macro-, meso-, micro-, and nanoplastics) are contaminants of emerging concerns that have since evolved to be a global environmental threat. Despite increasing levels of pollution in aquatic ecosystems, there are insufficient monitoring data to evaluate the extent of the catastrophe. Traditional methods of monitoring plastics in water are constrained by high sampling costs, intensive labor, and limited temporal and spatial coverage, which results in limited monitoring data. Thus, insufficient monitoring data limit our understanding of the true quantities and persistence of plastic particles in aquatic ecosystems, as well as the extent to which they impact the aquatic environment. There is increasing availability of free big geospatial data (amounting to petabytes/day) from satellite sensors for potentially monitoring plastics. This provides a possible solution to these challenges by minimizing the fieldwork required and therefore reducing the costs and sampling time. The study purpose of this review is to analyze advances in emerging technology such as the use of satellite sensors to monitor the occurrence of macro- and microplastics in freshwater, ultimately aimed at creating new operational monitoring solutions. This review: (1) examines the literature to identify trends, accomplishments, and limitations of using satellite data to monitor plastics in water; (2) identifies and compares traditional, and machine and deep learning satellite image classification methods for monitoring plastics in water; and (3) identifies research gaps and summarizes future perspectives and recommendations to improve monitoring methods.
The Hyperboloidal Universe
Authors: Laforet Christopher
Published: September 2022

This paper proposes a relativistic model of the Universe in which the geometry describes a 4D version of the 2-sheeted hyperboloid that is isotropic, homogeneous in space at a given time and inhomogeneous in time. The radius of this metric is temporal as opposed to spatial. It predicts both a Universe and Anti-Universe moving in opposite directions of time undergoing an expansion phase, followed by a collapsing phase. Using only the current age of the Universe and transition redshift, it predicts the accelerated expansion and it is shown that its Hubble diagram fits currently available supernova and quasar data as well as predicting a Hubble constant $H_0\approx71.6km/s/Mpc$. The angular term of the metric describes time dilation caused by the relativistic kinematic precession effect known as Thomas Precession which can be interpreted as spin about the time dimension. The model also makes two novel predictions: that the early Universe should have structures older than expected due to an increased amount of proper time relative to coordinate time in that era and that the background Universe should appear brighter than current models predict.
Open Data Policy, E-Commerce Connectivity and Portfolio Size Predict a Global Brand’s Online Popularity
Authors: Hoogeveen Martijn
Published: September 2022

Background Content marketing is increasingly important for online branding. Brand popularity can be more easily determined online than sales-based measures but is not yet well-explained from a content marketing perspective. Promising predictors are open data syndication policies, connectivity to e-commerce platforms, product reviews, data health, and the depth and width of a brands product portfolio. A predictive content marketing model can help brand owners to understand their e-commerce potential. Methods We used brand popularity (Brand Popularity Rank) and catalog data in combination with product reviews from an independent content aggregator. For all datasets, we selected the overlapping dataset for brand popularity and brand reviews based on a period of 90 days from June 10, 2022, till September 24, 2022 (n = 333 brands). Backward stepwise multiple linear regression was used to develop a predictive content marketing model of the Brand Popularity Rank. Results Through stepwise backward multiple linear regression five highly significant (p < 0.01) predictive factors for brand rank are selected in our content marketing model: the brand’s data syndication policy, the number of connected e-commerce platforms, a brand’s number of products, its number of products per category, and the number of product categories in which it is active. Our model explains 78% of the variance of Brand Popularity Rank and has a good and highly significant fit: F (5, 327) = 233.5, p < 0.00001. Conclusions We conclude that a content marketing model can adequately predict a Brand Popularity Rank based on online popularity. In this model an open content syndication policy, more connected e-commerce platforms, and catalog size, i.e., presence in more categories and more products per category are each related to a better (lower) Brand Popularity Rank score.

Understanding the potential flood inundation depth and extent over river basins can provide a reference for understanding and mitigating the flood risk. However, the development of design hyetographs for the evaluation of flood inundation under extreme rainfall is challenging. We evaluated the flood inundation depth and extent in the Chao Phraya River Basin, one of the largest river basins in Asia, which is often vulnerable to water-related disasters. Rainfall data from 119 stations within the basin were collected for a frequency analysis. After processing the 36-year daily rainfall data, a frequency analysis of the maximum monthly rainfall was performed at each station using the Gumbel distribution. The maximum monthly rainfall for various return periods varied substantially among stations. For an inundation analysis over the entire river basin, we produced design hyetographs by integrating extreme rainfall values for each month according to the return period. These design hyetographs were included in a rainfall-runoff-inundation model to simulate the maximum inundation depth profile over the basin for different return periods. The Maximum inundation depths were 8.3, 9.0, 9.7, and 10.5 m for return periods of 50, 100, 200, and 500 years, respectively, over the Chao Phraya River Basin. Similarly, approximately 16.3%, 17.1%, 17.8%, and 18.6% of the basin area was inundated (depth > 0.5 m) over the return periods, respectively. The results of this study provide a good reference for risk analyses and evaluations of the Chao Phraya River Basin.

Area-business continuity management (Area-BCM) is a concept that upgrades an individual business continuity management (BCM) to regional management to ensure the resilience of local economics and communities. In order to implement Area-BCM in an industrial park, various stakeholders, such as private companies, infrastructure providers, industrial park operators, disaster management authorities, and local governments, present several challenges. Therefore, this study aims to present the ways to achieve Area-BCM implementation with many stakeholders. The systematic review is conducted to find the critical success factors (CSFs) of Area-BCM. The concept of BCM and supply chain management are applied to search for related articles. Preferred reporting items for systematic reviews and meta-analyses approach is used as a guideline for the quality review. As a result, 14 CSFs are listed and categorized in four groups following the main dimensions of Area-BCM. In addition, we conduct a focus group study and interview experts from the public and private sectors. Their outlook enlightens the importance of collecting factors. Commitment and support from the top management are mentioned as the initial point of implementation. Equally, information and knowledge sharing is key to conveying the Area-BCM framework and related information to stakeholders. Government support is necessary to connect stakeholders through a regional network for disaster management. Lastly, the interrelationship of CSFs is drawn based on experts’ opinions.

Information sharing by related organizations is crucial in disaster response. In the event of a large-scale disaster that makes it difficult for the affected local government to respond independently, support from the central government and non-affected local governments is required. In such cases, effective activities by support organizations cannot be expected unless sufficient information is shared. The authors are currently working on the research and development of a platform for sharing information held by related organizations in a Japanese government project. In particular, they focus on the common operational picture (COP) necessary for effective activities by unifying the situational awareness of related organizations. This paper reports on the progress of the project, which commenced in 2014, and introduces current issues, directions for solving them, and efforts toward the advanced use of disaster information. Based on the results of a questionnaire distributed among local governments nationwide at the beginning of the project, the authors provide an overview of the state of disaster information system development in 2014. Based on the experience of actual disaster response, the authors will discuss the activity status of the Information Support Team (ISUT), the current status and issues of Shared Information Platform for Disaster Management (SIP4D), and NIED-Disaster Information-Sharing System (NIED-DISS).

Several earthquake incidents in the East Java province have resulted in numerous disadvantages such as damaged buildings and victims that were physically and emotionally wounded. The problem that has arisen in these situations is how victims of natural disasters often receive late responses and little to no information about relief efforts from authorities. Local governments and disaster relief organizations have not initiated the right method of communication to give important information toward disaster victims when information technologies have developed rapidly. The present study opt for a qualitative research design to conduct the interviews from the victims of disaster living nearby Malang and Blitar regencies of Indonesia. It examines how people living in earthquake-prone regions are communicating during the disaster using smartphones and social networking services. The findings of the research show that people living in the disaster-risk areas use mobile phones, smartphones, and social networking services in their daily life; yet, not many of them using these devices and services to look for information about earthquakes. Although authorities have created digital channels as a source of information, it does not receive significant attention and interest of the people at risk. The problems with uneven digital media literacy and lack of resources remain unresolved. Cooperation between authorities and people is expected, to ensure that the use of existing communication technologies becomes more effective and efficient in earthquake relief efforts and countermeasures.

Expectant and nursing mothers need to prepare for natural disasters to protect their lives and their children’s lives and to maintain their health and daily life after the disaster. This study aimed to clarify the actual conditions of disaster preparedness behaviors of expectant and nursing mothers and to identify factors promoting disaster preparation behavior and behavioral intentions that lead to disaster preparation behavior among expectant and nursing mothers. We conducted a cross-sectional survey involving 1,000 expectants and nursing mothers between October 2020 and January 2021 using an anonymous self-administered questionnaire. We received 135 valid responses. The questionnaire included items about the actual status of disaster preparation, attitudes toward preparation behavior based on Ajzen’s theory of planned behavior, subjective norms on disaster preparation determined by perceived expectations from others, descriptive norms on disaster preparation that refer to the perceptions of others’ engagement in disaster preparation behavior, perceptions of behavioral control that refer to views regarding how easy or difficult it is to perform a given behavior, and social support sources that are required for disaster preparation behavior. Correlations among variables were analyzed. A structural equation modeling technique was used to test a model to explain factors encouraging expectant and nursing mothers to prepare for disaster.

Published: September 2022

Silent underwater actuation and object detection are desired for certain applications in environmental monitoring. However, several challenges need to be faced when addressing simultaneously the issues of actuation and object detection using vision system. This paper presents a swimming underwater soft robot inspired by the moon jellyfish (Aurelia aurita) species and other similar robots; however, this robot uniquely utilizes novel artificial muscles and incorporates camera for visual information processing. The actuation characteristics of the novel artificial muscles in water are presented which can be used for any other applications. The bio-inspired robot, Jelly-Z, has the following characteristics: (1) The integration of three 60 mm-long twisted, and coiled polymer fishing line (TCPFL) muscles in a silicone bell to achieve contraction and expansion motions for swimming; (2) A Jevois camera is mounted on Jelly-Z to perform object detection while swimming using a pre-trained neural network; (3) Jelly-Z weighs a total of 215 g with all its components and is capable of swimming 360 mm in 63 seconds. The present work shows, for the first time, the integration of camera detection and TCPFL actuators in an underwater soft jellyfish robot, and the associated performance characteristics. This kind of robot can be a good platform for monitoring of aquatic environment either for detection of objects by estimating the percentage of similarity to pre-trained network or by mounting sensors to monitor water quality when fully developed.

Opportunities for lead exposure are common in the United States. The American Academy of Pediatrics, in collaboration with the Centers for Disease Control and Prevention, launched the Increasing Capacity for Blood Lead Testing Extension for Community Healthcare Outcomes (ECHO) project to educate pediatricians on the importance of testing children for lead exposure and to assess practice behavior change. We found that two weeks to one month after receiving training, more than 80% of participants reported increased lead testing and practice changes. Our results support use of the ECHO model as a mechanism for practice change. (Am J Public Health. 2022;112(S7):S647–S650. https://doi.org/10.2105/AJPH.2022.307084 )

Objectives. Despite the efficacy of surgical treatments, the high rate of recurrence in juvenile nasopharyngeal angiofibroma (JNA) after surgery remains an unresolved problem. The present study comprehensively analyzed the risk factors and characteristics of JNA recurrence, providing clinical guidance for reducing recurrence.Methods. A total of 123 patients who underwent surgery for JNA between 1997 and 2019 at a single hospital were analyzed retrospectively. Univariate and multivariate analyses were used to assess the clinical risk factors for the recurrence of JNA. The relapse-free survival and annual cumulative recurrence rates were analyzed for subgroups defined according to clinical parameters.Results. After screening, 78 of the 123 patients were included in the present study. The main risk factors associated with JNA recurrence included the year of diagnosis, tumor size, sphenoid bone invasion, Radkowski stage, surgical approach, and intraoperative bleeding. Importantly, the surgical approach and sphenoid bone invasion were independent prognostic factors affecting recurrence. Patients who underwent endoscopic surgery without sphenoid bone invasion exhibited longer relapse-free survival. In the present study, the overall cumulative recurrence rate of JNA was 38.7%, and recurrence occurred mainly in the first year after the initial surgery.Conclusion. Endoscopic surgery achieved better relapse-free survival in JNA patients, and patients with sphenoid bone invasion should be carefully explored to avoid residual JNA. The recurrence rate of JNA differed among subgroups defined based on clinical parameters and was highest in the first year after surgery. Computed tomography or magnetic resonance imaging, along with close follow-up, should be performed strictly within 1 year after the primary operation.

PT. Kharisma S.F is a company that produces sporty shoes with the Eagle, Nevada, and Fladeo brands. PT. Kharisma experienced a defect in the production process, which occurred in the sewing process and assembly process. However, the most common disability experienced by PT. S.F's charisma is a defect in the sewing process. This research focuses on the inspection of the production of Eagle brand shoes. With these problems, it is necessary to carry out quality control, which is useful for regulating the various products produced so that they can have good quality. To determine the level of a defect in the DPMO value and sigma value, to find out the various factors that cause the high level of product defects, and to provide suggestions for improvement and quality control to reduce the number of product defects, Root Cause Analysis (RCA) and Lean Six Sigma methods were used. Data were obtained from the company for three months and from 6 respondents to identify waste. From the results of research conducted. It can be seen that the factor that most influences the length of waiting time in production is the human factor. The highest identification of waste is defects. There are two types of defects, namely sewing defects and assembly defects. As for alternative improvements to reduce the number of defects, namely checking machine parts on the production floor with a checklist every day and replacing machine parts that are damaged or have expired, and providing regular training to operators scheduled once every three months.

The ability to detect buried objects is critical for the Army. Therefore, this report summarizes the fourth year of an ongoing study to assess environ-mental phenomenological conditions affecting probability of detection and false alarm rates for buried-object detection using thermal infrared sensors. This study used several different approaches to identify the predominant environmental variables affecting object detection: (1) multilevel statistical modeling, (2) direct image analysis, (3) physics-based thermal modeling, and (4) application of machine learning (ML) techniques. In addition, this study developed an approach using a Canny edge methodology to identify regions of interest potentially harboring a target object. Finally, an ML method was developed to improve automatic target detection and recognition performance by accounting for environmental phenomenological conditions, improving performance by 50% over standard automatic target detection and recognition software.
Valoración cultural y paisajística de conjuntos poblacionales rurales: comarca del Altiplano (Murcia/Sureste de España)
Authors: Sánchez-Sánchez Miguel Ángel , Albacete Moreno Alfonso
Published: September 2022

Los asentamientos humanos rurales forman parte del patrimonio cultural y paisajístico de Europa, y su valoración objetiva es fundamental para establecer programas de recuperación y desarrollo, constituyendo el objetivo fundamental de este trabajo. Para ello, se estableció una metodología cuantitativa basada en el análisis, mediante ecuaciones ponderadas, de dos áreas o coronas, una interior y otra exterior, de los núcleos poblacionales, que permitía obtener un valor numérico global denominado “valor cultural y paisajístico”. Esta metodología fue aplicada a una selección de 9 asentamientos humanos rurales de la comarca murciana del Altiplano. Los asentamientos que mostraron valores más altos albergaban elementos con mayor valoración arquitectónica y natural, destacando Fuente del Pino, por su huerta tradicional y la presencia de elementos arquitectónicos significativos, y Santa Ana del Monte, por estar situado en un enclave natural protegido y contar con un antiguo convento. Por el contrario, Casas de Pinillos, situado en una zona esteparia con intensa transformación agrícola, fue el asentamiento que presentó un valor más bajo.  Por tanto, el abordaje objetivo, mediante ecuaciones, de la valoración cultural y paisajística de los conjuntos poblacionales rurales permite una aproximación sencilla, pero a la vez muy robusta, sobre su potencialidad de desarrollo, que está abierta a posibles modificaciones y mejoras en función del grado de profundización requerido.

Authors: Godenau Dirk , Martín-Rodríguez Gloria , González-Gómez José Ignacio , Cáceres-Hernández José Juan
Published: September 2022

The territorial dimension of transactions between grape growers and wine producers in the Canary Islands’ grape market is examined. This is a market fragmented into different wine-grape zones and institutionally organised through protected designations of origin (PDOs) which, except in the case of one that is regional in scope, restrict the spatial mobility of grapes. We use information from the harvest declarations submitted by grape growers, which indicate the location of the vineyard plots, and production declarations submitted by the wine producers, which indicate the grape grower who supplies grapes to their winery, as well as from harvest reports, which contain a record that facilitates the traceability of the grape's journey from the plot of origin to the winery of destination. The results obtained show that there are hardly any inter-island movements of grapes and that inter-zone transactions were selectively intensified between the wine-grape zones of the island of Tenerife following the creation of a regional PDO.
Democratising the interface research-policymaking in landscape planning: experiences in Friuli Venezia Giulia (Italy)
Authors: Michelutti Enrico
Published: September 2022

In the current, extended socio-environmental crisis, the interface research-policymaking in landscape planning has evolved, seeking responses to pressing global dynamics (e.g., climate change, international migration fluxes, etc.) and critical local demands (e.g., recognition of community-based initiatives, “public governance” of landscape interventions, etc.). Depending on contextual conditions, different political agendas and legal frameworks shape the interplay between knowledge production mechanisms and practices on landscape. The evolution of the interface research-policymaking involves the interactions between structured research policies and informal knowledge generation processes, the (ideological) use of participation in the actions on landscape and the redefinition of power equilibria in the planning arena. Exploring the experiences of landscape planning developed in Friuli Venezia Giulia, Italy (i.e., territorial plans involving landscape conservation norms, regional landscape plans, “integrated landscape projects”), the research shows the need to readdress landscape governance and policymaking towards inclusiveness, fostering knowledge co-production initiatives at all levels and (re-)thinking power as a complex factor of change in the relationships between planning authorities, academia, communities and citizens.

El análisis de las redes de actores en los destinos turísticos ha cobrado importancia en la literatura científica. En este artículo, la aplicación de la metodología de redes ARS en cuatro ciudades de Ecuador, permite conocer la estructura de sus relaciones y fortalezas a través de un conjunto de indicadores como la densidad y la centralidad, enfocada esta última desde su grado de entrada (outdegree), es decir el número de relaciones directas que los actores dicen tener y su grado de salida (indegree), o sea el número de veces que un actor es nombrado por otro actor. El resultado de este estudio muestra que cada ciudad presenta una dinámica diferente en relación a su nivel de participación y relación en la red, destacando los actores del sector público y los distintos gremios y asociaciones, ubicándose en un menor grado los actores que no cuentan con estas fortalezas.

Background: High prevalence of vitamin D deficiency in sunshine-abundant countries is paradoxical. This necessitates a better understanding of the determinants of sun exposure practices. This study investigates how risk perceptions regarding sun exposure might influence relevant habits among the young adults and whether it might have any link to vitamin D deficiency in the community.
Methods: A descriptive cross-sectional survey was conducted from August 2019 to February 2020 using a pretested structured questionnaire focusing on knowledge, attitude, and practices regarding sunlight and vitamin D among college and university-level students in Bangladesh. A total of 3,812 students from 25 different institutions were enrolled. Descriptive and inferential statistics were used to analyze the responses.
Results: Among the respondents, 52% thought regular sunlight exposure would be harmful to health, and 29% thought the intensity of ultraviolet (UV) radiation in Bangladesh was very high. While 79% believed direct sunlight should only be sought ‘sometimes’, 9% thought it should be totally avoided. At least one sun-protection item was used by 72% of respondents, while 52% thought sunscreen should be used always when outdoors. A negative attitude to sunlight was significantly more prevalent among the females (p < 0.01). Knowledge about the symptoms of vitamin D deficiency and its potential health effects was generally very low. Only 12% of the participants correctly identified 10 am to 3 pm as the best time to get vitamin D from sunlight. Only 22% took vitamin D ever, and 7% ever checked their serum levels.
Conclusion: This study highlights some crucial determinants of sun exposure practices that can partially explain high vitamin D deficiency in sunshine-abundant regions. Findings and insights from this study could be generalizable for other countries with comparable socio-demographic settings and will facilitate adopting more sustainable policies to address vitamin D deficiency globally.

The search for development in an economically sustainable and ecologically correct way is an objective of modern society that has been investing in products that reduce their impacts on the environment, especially in relation to the use of plastic, which is very harmful to nature due to its toxicity and time of stay in the middle. The present study aims to analyze the feasibility of producing blocks made of concrete with different amounts of plastic taken from coastal and estuarine areas. After analysis in the laboratory, it was found that the blocks with 5% of plastic have good compressive strength, are lighter, there was an increase in the acidity of the sample, a decrease in the density of the block, a reduction in the flexural strength, a reduction in the compressive strength. The prototype with 5% of plastic by mass is efficient for the construction of single-story houses, meeting the minimum requirements of normative resistance, allowing the shielding of the plastic in the block, reducing the impact on the environment.

The present study investigates the influencing factors responsible for the asymmetry in aerosol optical depth (AOD) trends using long-term datasets (2003-2019)over western and eastern Indo-Gangetic Plain (IGP) regions during the pre-monsoon season. Analysis from MERRA-2 for different aerosols illustrates that dust aerosols dominate over the western IGP (W-IGP), while sulphate and carbonaceous aerosols (black carbon (BC) and organic carbon (OC)) majorly contributed to the total AOD over the eastern IGP (E-IGP). Our study reveals a significant decline in AOD over the W-IGP, while a rising trend over E-IGP from satellite (MODIS) and Modern-Era Retrospective analysis for Research and Applications Version-2 (MERRA-2) data. A dipole pattern in AOD trends over IGP indicates the aerosol loading from combined effects of various natural and anthropogenic emissions under favourable meteorological conditions over the west and east IGP, respectively. Furthermore, the declining AOD trend over W-IGP is mainly attributed to increased pre-monsoonal rainfall, which supports the wet deposition and increases soil moisture, thus reducing soil erodibility, and correlates strongly with meteorological factors. The rising AOD trend over the E-IGP appears to be influenced by increased anthropogenic emissions (i.e., BC, OC, and sulfate) from industrialization of the region, decreased rainfall and enhanced westerly-induced advection of aerosols from W-IGP. Our study indicates that the regional meteorological variables and anthropogenic sources influence changes in the AOD trends over the IGP region.

Unfolded protein response (UPR) plays a critical role for preventing death of cardiomyocytes induced by excessive endoplasmic reticulum (ER) in response to cytotoxicity of anthracycline antineoplastic drugs through mitigating misfoled proteins accumulation in the hearts. Here, we demonstrate that ER-selective autophagy (ER-phagy) serves as a salvage system which enable cardiomyocytes to survive even if UPR fails to restore ER stress induced by doxorubicin (Dox), an anthracycline drug, by using in-house developed monitoring systems to evaluate the activity of ER-phagy in cardiomyocytes. Notably, ER-phagy contributes to relieving cardiac damage induced by Dox administration and is mediated by CCPG1, an ER-phagy receptor protein. Furthermore, ablation of CCPG1 abolished ER-phagy and worsened Dox-induced cardiac damage by inducing excessive ER stress-associated apoptosis. Our data highlight a compensatory role of CCPG1-driven ER-phagy in reducing Dox toxicity and pose a potential therapeutic target to intervene against Dox induced cardiomyopathy.

Activity-based lead screening and druggability-based structure optimization are usually torn into two independent processes, although both are related to the chemical structure of target compounds. It leads to an unsatisfactory success ratio and inefficient drug development. DeepRLADS, a de novo molecular design assay, was established based on deep reinforcement learning training, integrating activity screening and structure optimization into a single artificial intelligence (AI)-based drug discovery module. Targeting the relatively easy-verified porcine epidemic diarrhea coronavirus (PEDV) main protease (Mpro, 3CLpro), a diverse virtual library of potential 3CLpro inhibitors was created by splitting existing inhibitors, digitizing fragments, and de novo design, focusing on their potential biological activities and pharmacological properties. The AI-designed compound 11b has a novel catechol-pyrazoline structure, presenting efficient inhibition against Mpro, surprising protection against PEDV infection, low toxicity, and favorable pharmacokinetic properties in vitro and in vivo. Low-dose oral 11b (5 mg/kg) reversed PEDV-induced diarrhea in 5-day-old piglets and greatly improved the survival rate (from 0% to 100%). A preclinical study (560 cases) in eight independent farms indicated an inspiring recovery rate (survival rate: 95.8% in treated piglets VS 9.1% in untreated piglets). Compound 11b is the first proven chemical efficiently protecting piglets in a large-scale preclinical study with multiple centers. It suggested that the novel strategy used by DeepRLADS was a hopeful approach for further AI-based drug design.
