ARM-Stream: Active Recovery of Miscategorizations in Clustering-Based Data Stream Classifiers
Authors: Cavalcanti Douglas Monteiro , Cerri Ricardo , de Faria Elaine Ribeiro
Published: April 2023

The design of classifiers involves learning the probability distribution of data classes from labeled samples. Traditionally, this problem assumes a single estimation of the distribution, but recent advancements in data generation have led to non-stationary data streams where the distribution is subject to concept drift and evolution. In such cases, classifiers that can incrementally update their estimates of the distribution are advantageous. Among them, clustering-based classifiers gain prominence for using unlabeled data in the update process. These classifiers generate new clusters from partially or completely unlabeled data, categorizing each as either an existing class extension or a new one. However, to determine class information through unlabeled data, these classifiers depend on assumptions about feature-class interaction that can become invalid as the distribution changes, leading to incorrect updates. To address this problem, we propose ARM-Stream, an active-learning framework for improving the reliability of clustering-based data stream classifier updates by providing label information where the process would otherwise fail. We demonstrate the effectiveness of ARM-Stream in detecting and correcting miscategorizations through experiments on synthetic and real-world datasets, integrating the framework into two clustering-based data stream classifiers from the literature: MINAS and ECHO. The source code used in the experiments is provided.
Accelerating Atmospheric Gravity Wave Simulations using Machine Learning

Published: April 2023

Gravity waves (GWs) and their associated multi-scale dynamics are known to play fundamental roles in energy and momentum transport and deposition processes throughout the atmosphere. GWs are well described by the Navier-Stokes equations, but solving these equations extending to very small scales remains daunting, and is limited by the computational costs of resolving the smallest important spatio-temporal features in a large-scale environment. This has led to developments of a wide variety of GW parameterization schemes for regional and global atmospheric models. Traditionally, GW parameterizations are based on linear theory, and no parameterization of secondary GWs (SGWs) has been developed to date. In addition, there remain many aspects of GW dynamics (e.g., GW self-acceleration, instability, GW breaking, SGW generation, and multi-scale interactions) that are important to describe, but cannot be addressed by linear theory or existing schemes.
Here we describe an initial, two-dimensional (2-D), machine learning model – the Compressible Atmosphere Model Neural Network (CAMNet) - intended as a first step toward a more general, three-dimensional, highly-efficient, model for applications to nonlinear GW dynamics description. CAMNet employs a physics-informed neural operator and GPU hardware to dramatically accelerate GW and SGW simulations applied to two GW sources to date. CAMNet is trained on high-resolution simulations by the state-of-the-art model Complex Geometry Compressible Atmosphere Model (CGCAM). Two initial applications to a Kelvin-Helmholtz instability source and mountain wave generation, propagation, breaking, and SGW generation in two wind environments are described here. Results show that CAMNet can capture the key 2-D dynamics modeled by CGCAM with high precision. Spectral characteristics of primary and SGWs estimated by CAMNet agree well with those from CGCAM. Our results show that CAMNet can achieve a several order-of-magnitude acceleration relative to CGCAM without sacrificing accuracy and suggests a potential for machine learning to enable efficient and accurate descriptions of primary and secondary GWs in global atmospheric models.

Published: April 2023

Given the importance of skin of color (SoC) representation in dermatologic education and training, this study quantified representation of Fitzpatrick skin phototypes (FST) in core dermatology surgery textbooks. Images within Surgery of the Skin: Procedural Dermatology, Dermatologic Surgery, and Facial Reconstruction after Mohs Surgery were categorized according to the Fitzpatrick skin phototype (FST) depicted and the dermatologic surgery topic addressed. 1501 images were analyzed, with only 5.6% of the images categorized as FST IV-VI representing SoC. Several topics (11/29, 37.9%) identified did not include images with SoC. Increasing access to high-quality images of SoC can enhance appreciation of various skin conditions, especially those predominant in SoC, by dermatologic trainees and clinicians.
Influence of electrode reactions on electroosmotic flow and ion transport in a microchannel

Published: April 2023

Electroosmotic flow (EOF) is a universal phenomenon in most microfluidic systems when an external electric field exists along charged channel walls. The mechanism of ion transport and fluid flow in such systems has been extensively studied, largely based on simplified models without consideration of electrode reactions and water dissociation. In order to study the effects of these electrochemical reactions, we build an electrokinetic model with full consideration of these processes, namely electrochemistry (EC) model, and compare its performance with that of the traditional electrokinetic (EK) model. Our results show that electrode reactions alter the electric potential and reduce the current, causing a significant reduction in EOF velocity. These potential changes and EOF reduction are driven almost entirely by electrode reactions because the difference between the results from the EC model and those from the EK model with potential adjustment induced by chemical reactions is slight. In addition, the participation of ions in electrode reactions leads to notable alterations in their concentration within the microchannel and significant pH change, which are totally ignored in the traditional EK model. It is found that at a typical applied electric field of 50 V/cm, the EOF velocity in the EC model is 64% of that in the EK model. This difference in velocity decreases to only 1.9% as the EK model considers electric potential shifts caused by electrode reactions. In the microchannel, the Cl− concentration drops by approximately 50% while the OH− increases, leading to a pH growth of 3.5. The results presented in this work can improve the understanding of electrode effects on the physicochemical properties of EOF systems, providing essential guidance for manipulating fluid flow and amphoteric molecular transport in various microfluidic systems.

Published: April 2023

Background
This study aimed to retrospectively evaluate the treatment strategies and possible prognostic factors in patients with brain metastases (BMs) from colorectal cancers (CRC).
Methods
We retrospectively reviewed 40 patients with BMs from CRC who were treated at our center between July 2011 and May 2022. Clinicopathological characteristics and clinical outcomes were analyzed.
Results
The median follow-up time was 3 (range, 0.5–28) months. The median survival time after diagnosis of BMs was 4 months. The 1-year survival rate was 9.5%. In the univariate analysis, the absence of extracranial metastases was significantly associated with better overall survival (OS) but not intracranial progression-free survival (iPFS), while Eastern Cooperative Oncology Group performance status, recursive partitioning analysis (RPA) classification and local treatment of BMs were significantly associated with iPFS and OS. Multivariate analysis showed that only local treatment of BMs influenced the iPFS and OS. In addition, the OS was better in patients with intracranial benefit. The median time interval between the diagnosis of the primary tumor and BMs was 28 (range, 2–107) months. Among these BMs, 16.2% of the BM occurred within the first year after diagnosis of the primary tumor, 43.2% in the first 2 years, and 67.6% in the first 3 years.
Conclusions
local treatment of BMs was an independent prognostic factor for patients with BMs from CRC. Earlier detection followed by an aggressive local therapeutic approach for BMs had a great influence on treatment outcomes as well as the long-term prognosis and quality of life.
Swin-RGC: Swin-Transformer with Recursive Gated Convolution for substation equipment non-rigid defect detection
Authors: Li Hui , Zhang Jie , Li Rui , Zhang Hui , Zou Le , Liu Shujuan
Published: April 2023

Substation equipment defects are important factors affecting the safe operation of power grids. However, many non-rigid defects have low detection accuracy and poor robustness,due to boundary ambiguity, irregular shape and tiny size. To address these problems,we propose a swin-transformer with recursive gated convolution framework for substation equipment non-rigid defect. Firstly, in order to effectively detect non-rigid defect objects to improve the discriminability of image features, we design the Swin-Transformer with Recursive Gated Convolution(Swin-RGC) framework to extract the interaction features between spaces in the deep model. Secondly, to avoid the loss of object location information, the Task-aligned One-stage Object Detection(TOOD) head is improved by fusing Coordinate Attention modules. Finally, a substation equipment defect detection dataset is established to provide a baseline for detecting non-rigid defects in substation power equipment. Experiment results on our dataset demonstrate that our proposed method achieves the performance of 69.9% Mean Average Pricision (mAP) in the substation equipment non-rigid defect detection, which outweighs the state-of-the-art approaches.

Published: April 2023

Available water for urban landscape irrigation is likely to become more limited because of inadequate precipitation and the ever-increasing water demand of a growing population. Recent droughts in the western United States have also increased the demand for low-water-use landscapes in urban areas. Penstemon species (beardtongues) are ornamental perennials commonly grown in low-water-use landscapes, but their drought tolerance has not been widely investigated. The objectives of this study were to determine the effects of water availability on the morphology, physiology, and canopy temperature of Penstemon barbatus (Cav.) Roth ‘Novapenblu’ (Rock Candy Blue® penstemon), P. digitalis Nutt. ex Sims ‘TNPENDB’ (Dakota™ Burgundy beardtongue), P. ×mexicali Mitch. ‘P007S’ (Pikes Peak Purple® penstemon), and P. strictus Benth. (Rocky Mountain penstemon). Twenty-four plants of each penstemon species were randomly assigned to blocks in an automated irrigation system, and the substrate volumetric water content was maintained at 0.15 or 0.35 m3⋅m−3 for 50 days. The decreased substrate volumetric water content resulted in a decreased aesthetic appearance of the four penstemon species because of the increased numbers of visibly wilted leaves and chlorosis. Plant growth index [(height + (width 1 + width 2)/2)/2], shoot number, shoot dry weight, leaf size, and total leaf area also decreased as the substrate volumetric water content decreased, but the root-to-shoot ratio and leaf thickness increased. Photosynthesis decreased, stomatal resistance increased, and warmer canopy temperatures were observed when plants were dehydrated. Additionally, as substrate volumetric water content decreased, the leaf reflectance of P. barbatus and P. strictus increased. Penstemon digitalis, which had the highest canopy–air temperature difference, was sensitive to drought stress, exhibiting a large proportion of visibly wilted leaves. Penstemon ×mexicali, which had the lowest root-to-shoot ratio, had the lowest shoot water content of the species studied and more than 65% of leaves visibly wilted when experiencing drought stress. Penstemon barbatus and P. strictus, native to arid regions, exhibited lower canopy–air temperature differences and better aesthetic quality than the other two species. Under the conditions of this study, Penstemon barbatus and P. strictus exhibited better drought tolerance than P. digitalis and P. ×mexicali.
Can Rare Cancer Drugs Expect Sales in Japan?: A Prescription Pattern Analysis of Drugs for Chronic Myelogenous Leukemia and Neuroendocrine Tumor
Authors: Shibata Shoyo , Noguchi Emi , Matsushita Maiko , Suzuki Takeshi , Ozaki Koken
Published: April 2023

Despite high unmet medical needs, investment in rare cancer drug development has stagnated, likely because the potential market for such drugs is small. In this context, we hypothesized that rare cancer drugs could achieve a higher sales margin. A dataset was created from publicly available information obtained from the IQVIA Solutions Japan K.K. Pharmaceutical Market database on the website of the Pharmaceuticals and Medical Devices Agency/Ministry of Health, Labour and Welfare of Japan. The total amount of sales and prescription volumes between 2010 and 2016 for drugs whose indications include chronic myelogenous leukemia (CML) and neuroendocrine tumor (NET) were investigated. Regarding drugs for CML, the sales and prescription volumes of imatinib have been decreasing every year, whereas those of dasatinib and nilotinib have been increasing. Regarding drugs for NET, the sales and prescription volumes of sunitinib, everolimus, and streptozocin have been increasing every year. The present study revealed two sales models for the development of rare cancer drugs. First, sales amounts can be assured if clinical positioning with other existing drugs is sufficiently clear. Second, obtaining a label for rare cancers can stimulate drug development for more common cancers. These findings suggest that rare cancer drugs can offer high market value and profit potential; thus, to meet high unmet medical needs, clinical development programs for the development of rare cancer drugs should be promoted. https://doi.org/10.21423/jrs-v07shibata

Objective:Depression and anxiety represent the most common expression of psychological distress in dialysis patients, and this distress is associated with a high mortality rate. Its prevalence, which varies from one study to another, remains underestimated. The objective of our study is to estimate the prevalence of depression and anxiety, in a population of chronic hemodialysis patients, and to identify the sociodemographic, clinical factors associated with them. Materials and Methods: Our study was carried out in the hemodialysis unit of the nephrology department of the Mohammed V military training hospital (HMIM V) in Rabat. It is a descriptive cross-sectional study conducted during June and July 2018, in 35 patients with chronic kidney failure, managed in periodic hemodialysis and who had given their free and informed consent to participate in the study. We used the Hospital-Anxiety and Depression Scale for the diagnosis of anxiety and depression. Results:Depression was found in 16 patients (45.7%) including 8 men and 8 women. The occurrence of depression was significantly related to gender, professional status, and the existence of somatic comorbidities. Anxiety was found in 21 patients (60%), including 10 men and 11 women. The occurrence of anxiety was significantly related to age, professional status, duration of professional status, duration of hemodialysis, existence of somatic comorbidities and professional status.

The purpose of this study was to evaluate the prescribing behavior of psychotropic drugs in non-psychiatric doctors, in the military hospitals of the south zone. The study was conducted over a six-month period, from May to October 2017, with a sample of 48 physicians from different disciplines and various medico-surgical services from the three hospitals. Physicians responded to an anonymous questionnaire mainly on the main drug classes prescribed psychotropic drugs, the main indications, and their frequency of prescription. The majority of physicians involved in all specialties are prescribers at variable rates. The rate of prescribers among neurologists, cardiologists, dermatologists, anesthesiologists, neurosurgeons, visceral surgeons and urologists was 100% while emergency physicians had a rate of 88.8%. In traumatologists, the rate was 75%. For ophthalmologists the rate was 50%. The rest of the specialties prescribed with a rate of less than 50%. The main psychotropic drugs prescribed were antidepressants and hypnotic / anxiolytic benzodiazepines, while the main indications were depression, anxiety disorders, insomnia and agitation. Virtually 44% of these prescribers were the initiators of treatment, and more than half of the presenters indicated that their knowledge of psychotropic drugs was limited to the therapeutic courses they received during their general medical training at the Faculty of Medicine. It is necessary to grant more hours to therapeutic courses at the faculties of medicine and pharmacy and to establish a compulsory continuing education for every doctor in the field of therapeutics and particularly that of psychotropic drugs, in order to ensure the respect of prescription rules for psychotropic drugs.

Introduction: Lichen sclerosus et atrophicus mainly affects the genital area. The palmo-plantar involvement is most often part of a diffuse cutaneous involvement, which is rarely exclusive. We report a case of acral lichen sclerosus et atrophicus, without any other involvement. Case Report: A 58-year-old man presented with lesions of the hands and feet, consisting of subungual hyperkeratosis and squamo-keratoticperi-onyxis of the toenails, sclero-atrophic ivorine plaques with depressed keratoticmicropapules on the soles and palm hollows, extending to the lateral and dorsal surfaces, with involvement of the interdigital and inter-toe spaces. There was no other cutaneous or genital involvement. Histological examination showed a lichen sclerosus et atrophicus appearance. Discussion: A few cases of lichen sclerosus et atrophicus limited exclusively to the feet and/or hands have been reported, affecting either the palmoplantar or dorsal surface, with or without ungual involvement. No case of lichen sclerosus et atrophicus affecting only the feet and hands on both surfaces with onychodystrophy, as in our case, has been reported.

Published: April 2023

Animal husbandry is one of the most important economic activities that humanity has been carrying out since its existence in order to meet the need for animal protein which has an important place in nutrition. In Turkey, on February 6, 2023, two destructive earthquakes with a magnitude of Mw=7.7 and Mw=7.6 occurred in the PazarcÃ„Â±k and Elbistan districts of Kahramanmaras in the south of Turkey. The earthquake caused the death of tens of thousands of our citizens in Adana, AdÃ„Â±yaman, DiyarbakÃ„Â±r, ElazÃ„Â±Ã„ÂŸ, Gaziantep, Hatay, Kahramanmaras, Kilis, Malatya, Osmaniye, SanlÃ„Â±urfa and seriously damaged our livestock. After the disaster, it was observed that many producers were unable to care for their animals due to the risk of epidemics that may arise from the animals that perished and the general damages that may arise from the loss of animals, especially the supply of feed, which is the most important problem for the animals that are rescued and currently kept. Delays in reaching rural areas during the earthquake revealed that a special structure should be established for villages in similar disasters. Structures such as intervention units for rural areas affiliated with AFAD can help with this.

A MODEL FOR PREDICTING THE NUMBER OF MASS-TRANSFER UNITS AND THE EFFICIENCY OF SIEVE TRAYS IN RECTIFICATION
Authors: Karaivanova Mariana , Koleva Desislava
Published: April 2023

The design of rectification columns is based on the method of thetheoretical tray and the actual setupof real trays is carried out with the help of various kinetic characteristics, such as tray efficiency. The relation between local and integral efficiency is a complex function of geometric, physicochemical and hydrodynamic factors. A theoretical method for calculating the tray efficiency has not yet been proposed, because of the complex hydrodynamic setting and the influence of a number of factors. Empirical correlations for calculating the local or integral efficiency of the traycan be found in the literature. The aim of the present work is to make a comparison between the calculated local efficiency data by means of a model known from the literature and the experimentally obtained data from the rectification of a model Tetrachloromethane-Toluene binary mixture in a laboratory single-sieve tray column. Among the tasks of the currentwork is also to determine the parameters of the applied model. The proposed method is semi-empirical and allows for the calculation of the number of mass-transfer units and, therefore,of the local efficiency.

During the full-scale war, educational institutions of Ukraine were at the epicenter of hostilities and suffered from attacks and bombing by the russian army: many schools, colleges, and universities were destroyed or damaged, and tens of thousands of students and teachers became refugees or forced displaced persons, lost their property and housing. Chernihiv Polytechnic National University (CPNU), located in the northern border region of Ukraine, was also significantly affected.This study aims to systematize the features of the functioning of CPNU under siege, bombing, and shelling. An analytical method was used to assess statistical reports available in open access on the official websites of CPNU and the Ministry of Education and Science of Ukraine. The paper identified that during active hostilities, 25% of the university’s infrastructure was destroyed by shelling and bombing; 37 teachers and researchers emigrated; about 4% of students stopped their studies. Currently, CPNU suffers from loss of human capital, physical destruction of educational and research infrastructures, lack of R&D financing, increased cyber security threats, and violation of the educational process. In response to military challenges, the university management rethinks and forms a new vision for further development based on sustainability principles to recover educational and research infrastructures, promote human capital development, and modernize the learning environment. The new vision of CPNU integrates “7R” principle – seven key pillars covering different directions of its operation (teaching, research, innovation, international activity, etc.).

Published: April 2023

In the conditions of the war of russia against Ukraine, which began on February 24, 2022, Ukrainian universities are playing roles that were not characteristic of them in peacetime. To the greatest extent, this concerns the university’s third mission, serving society and responding to its urgent needs. The purpose of this study is to identify and characterize new meaningful directions for implementing the third mission of the university in the conditions of war and post-war reconstruction. The study uses quantitative and qualitative bibliometric analysis combining various methods, in particular, quantitative and dynamic analysis of publications and citations, keyword analysis, cluster analysis and content analysis of publications.The study’s results proved the lack of conceptual studies devoted to the role of universities in the war and post-war reconstruction. The main clusters of implementing the third mission of universities and the existing and potential areas of activity of Ukraine’s universities during the war and post-war reconstruction that belong to them were determined. In conclusion, it is substantiated that a new dimension of the mission of universities is being formed, which is at the stage of its formation and needs time for the necessary transformations. Depending on the consequences of the war in Ukraine, it can be a separate cluster of the third mission of universities, and the selection of a new fourth mission of universities, dedicated to peacebuilding and the role of the university during the war and post-war recovery.

Sustaining academic commitment under adverse circumstances and adapting to new roles during the year of war: Example of Lesya Ukrainka Volyn National University
Authors: Tsos Anatolii , Makaruk Larysa
Published: April 2023

The full-scale russia-Ukraine war, which started in February 2022, created severe challenges in every domain throughout the country, including that of higher education. Therefore, educational authorities’ response to this crisis has become interesting and significant. The goal of this study is to highlight the experience of Lesya Ukrainka Volyn National University, exemplifying potential reactions to this new situation, analyzing the university’s overall structure and functioning, in particular, its continuing dedication to its long-term academic role while implementing crisis management measures during the martial law.The asynchronous teaching mode and unique linkages with LUVNU students and teachers residing outside the country illustrated the university’s commitment to its educational role. At the same time, staff and students of the university demonstrated their capacity to take on a totally new role, seeking ways to support the military and various population groups suffering from the full-scale invasion. This flexibility was reflected in a wide range of specific projects undertaken by different entities within the university, demonstrating their ability to devise initiatives that corresponded in some manner to their original field of study in the university, whether it be for the manufacture of specialized items or the opening up of personal support structures.

Published: April 2023

Ensuring a high quality of educational and scientific activity is one of the main tasks for university management, which becomes especially significant in wartime conditions. The results of scientific research and mechanisms worked out in practice to ensure the effectiveness of the university functioning and anti-crisis management techniques in wartime may become impractical, as they are usually considered relatively stable and even predictable in the short term by the external environment and regular internal communications. Therefore, the study aims to systematize managerial decisions and measures and conduct a SWOT analysis of the university’s functioning in war conditions when external risks are at their maximum level.Based on the accumulated experience of Sumy State University management, which continued its activities even when russian invaders surrounded the city, it demonstrated effective work in 2022 and 2023. It became possible thanks to the pre-war management system, coordination of the work of all structural divisions, and constant information of all participants in the educational process through an internal information system and electronic document management. The critical threats to the university’s functioning in the future have been determined based on the conducted SWOT analysis. The developed methods and mechanisms of university management could not be fully applied in war conditions; the management’s ability to make non-standard decisions is essential; the state of the university depends on the distance to the war zone, as well as the institutional conditions developed in the pre-war period; the university’s presence in international rankings expanded cooperation with international partners and provided many significant advantages in supporting the university’s educational and scientific activities; the prerequisites for the university’s financial stability in wartime are careful analysis and strict control of the economic situation.
The “Ukrainian Science Diaspora” initiative in the wartime
Authors: Polishchuk Yevheniia , Lyman Igor , Chugaievska Svitlana
Published: April 2023

The devastating russian military invasion of Ukraine forced millions of people to flee their homes. Among those affected are highly skilled scientists, resulting in a significant loss of human capital for Ukraine, which is crucial for the post-war reconstruction. To address this pressing issue, the Young Scientists Council (YSC) at the Ministry of Education and Science of Ukraine launched the “Ukrainian Science Diaspora” initiative to mitigate the brain drain.The purpose of this study is to outline the first steps taken by this initiative. Moreover, it demonstrates lessons learned from the pilot meetings. The essence of the initiative is to keep links with scholars who left Ukraine and join the efforts of different migration waves of Ukrainian scientists for the further rebuilding of Ukraine. The YSC and other institutions prepared the analytical report on the needs and plans of Ukrainian scientists abroad. In addition, the paper highlights various events and activities organized by the YSC and other self-formed associations of Ukrainian scientists worldwide, working together to establish networks that could take the form of public organizations or be part of local unions of scientists. At present, efforts are focused on identifying Ukrainian scientists interested in joining this initiative, with the ultimate goal of identifying areas where Ukrainian scientists can participate in post-war reconstruction. The success of this initiative will undoubtedly play a crucial role in ensuring that Ukraine can retain its valuable human capital and continue to thrive in the face of adversity.

So teachers are required to prepare various abilities in carrying out education and guidance to students by encouraging them to be independent in reaching maturity. The teacher's role can use various ways to generate learning motivation in students by doing: a) giving points, prizes, competitions, ego-involvement, giving tests, knowing results, praise, punishment, desire to learn, interests, and recognized goals. According to Abraham Maslow "Motivation is constant, never ending, fluctuant and complex, and that it is an almost universal characteristic af particulary every organism state of affairs". This definition from Abraham Maslow is interpreted by Fudyartanto, namely "motivation is constant (fixed), never ending, fluctuating and complex, and it is a universal characteristic of every activity of organisms.Referring to the educational philosophy of Empiricism put forward by the British philosopher, John Locke (1632-1704), he was a realist who believed that education occurred through real (empirical) experience. In line with the expression experience is the best teacher (experience is the best teacher), the application of empiricism in education, that educators are optimistic about being able to shape children by providing the desired experiences. SD Muhammadiyah 11 Mangkuyudan Surakarta by using a qualitative approach, from the results of the study it was found that teachers had carried out their duties well but there were still factors inhibiting the learning motivation of grade VI students at SD Muhammadiyah 11 Surakarta including: Lack of student willingness to learn, Lack of attention from parents, Factors of educators, association, community environment.

This study investigates the potential of a hybrid process combining sand filtration column with activated banana peels macrocomposite (ABPM) adsorbent for river water treatment. Scanning electron microscopy (SEM) analysis displayed an irregular structure and high cavities of the banana peel adsorbent surface that caters to the deposition of contaminants, while energy-dispersive X-ray analysis detected major elements of the adsorbent, such as calcium, oxygen, silicon, and carbon. Fourier-transform infrared analysis of the banana peels adsorbent showed the presence of hydroxyl, acyl, amine, and alkene groups that were responsible for the adsorption process. The sand filtration column experiment was investigated to find out the removal of turbidity, biochemical oxygen demand (BOD), chemical oxygen demand (COD), total suspended solids (TSS), and ammonia nitrogen (AN) where it resulted in the highest removal efficiency operated at a flowrate of 1.15 ml/s with >90% turbidity, 44% COD, 87% BOD, 75% TSS, and 54% AN removal. The adsorption isotherm was best described by the Langmuir model (R2 > 0.98) compared to the Freundlich model (R2 > 0.95). The pseudo-first-order kinetic model was the best fit for all the experimental data. The combination of sand filtration column with ABPM adsorbent is an efficient treatment solution for improving river water quality.

Thanks to their multifunctional properties, such as foaming, emulsifying and skin hydrating activities biosurfactants are potentially used in the cosmetic industry. In the present work, firstly, skin cream formulations using chemical surfactant agents and lipopeptide biosurfactants isolated from Bacillus subtilis SPB1 were investigated. The efficiency of the selected formula, containing 15% biosurfactant, was tested and its physicochemical properties were satisfying. In fact, it shows a spreading ability of 23 mm, a water activity of 0.72 and a pH value of 5. In addition, its biological activities were interesting showing a zone of inhibition against Gram-positive bacteria ranging from 8 to 15 mm. Moreover, it presents an antiradical effect against diphenyl-1-picrylhydrazyl (DPPH) with an IC50 of the order of 68 mg/mL. Second, seeking a highly stable SPB1 biosurfactant formulation for an easy commercial trend, a combination of biosurfactant, Gum Arabic (GA) and glycerol was optimized using the Box–Behnken (BB) design. As analysed, the model predicts an optimal value of the surface tension (ST) equal to 40.18 ± 0.39 mN/m when the respective values of the percentages of SPB1 BioS, glycerol and GA are equal to 72.62, 7.5 and 1.5%. Under these conditions, the emulsification index (EI)-24% is around 81.76 ± 0.14%.

Based on the available literature and a review of collections of organisms, a checklist of 69 myriapod species was made for the Colombian Caribbean region; two symphyls, 15 Chilopods, and 52 Diplopods. In total, 20 families (one from Symphyla, five from Chilopoda, and 14 from Diplopoda), from 11 orders (one from Symphyla, three from Chilopoda, and seven from Diplopoda). Each species's geographical range by department, altitud, reference collection, and bibliographic source were included. The presence in Colombian collections of diplopod specimens that are new records of their taxonomic group for the region, such as Chondrodesmus cf. riparius (Chelodesmidae), two species of Fuhrmannodesmidae, three of Paradoxosomatidae and one of Lophoproctidae. Likewise, two species of Scolopendrellidae of the class Symphyla. This demonstrates the urgent need to complete the essential diversity inventories of the main groups of organisms in the face of the alarming environmental deterioration to which the Colombian Caribbean region is subjected.

Published: April 2023

Se caracterizó la fauna de hormigas exóticas, evaluando su incidencia y variación en ambientes urbanos de la ciudad de Santa Marta. Como una aproximación de la heterogeneidad del paisaje urbano, se establecieron tres tipos de ambientes: parques distritales, parques temáticos y zonas naturales, los cuales exhiben diferencias principales en la cobertura arbórea y en la cobertura gris. En total, se seleccionaron 16 sitios distribuidos en los tres ambientes; cada sitio fue muestreado cuatro veces teniendo en cuenta las épocas climáticas. Las trampas de caída, sacos mini-Winkler, cebos y colecta manual fueron los métodos para recolectar las hormigas tanto nativas como exóticas. Se analizaron y compararon la riqueza y abundancia de especies de hormigas exóticas y nativas entre ambientes, microhábitats y épocas climáticas. Se registró la distribución en Colombia, así como información sobre su posible origen y distribución nativa para cada una de las especies exóticas encontradas. Se recolectaron siete subfamilias, 42 géneros, 88 especies y nueve morfoespecies. De las 97 especies recolectadas solo ocho corresponden a especies exóticas. Los parques urbanos registraron la mayor riqueza de especies exóticas a escalas espacial y temporal. Las frecuencias de captura y las curvas de rango-abundancia indican que Pheidole indica es la especie predominante en los parques distritales, mientras que Paratrechina longicornis y Trichomyrmex destructor son las más frecuentes en los parques temáticos. Paratrechina longicornis, Monomorium pharaonis y Tapinoma melanocephalum son de amplia distribución en Colombia; mientras que P. indica, T. destructor, Tetramorium lanuginosum, T. simillimum y Cardiocondyla emeryi se han registrado en pocas localidades en el país. Las áreas con mayores cobertura y diversidad vegetal presentaron un menor número de especies exóticas (zonas naturales y parques temáticos), mientras que aquellas con mayores superficies de concreto y una menor cobertura vegetal (parques distritales), concentraron mayores riqueza y abundancia de hormigas exóticas.
A Comprehensive Review on the Importance of MiRNA-206 in the Animal
Model and Human Diseases
Authors: Qi Wang , Guan Wei
Published: April 2023

MicroRNA-206 (miR-206) is a microRNA that is involved in many human diseases, such
as myasthenia gravis, osteoarthritis, depression, cancers, etc. Both inhibition effects and progression
roles of miR-206 have been reported for the past few years. High expression of miR-206 was observed
in patients with osteoarthritis, gastric cancer and epithelial ovarian cancer compared to normal people.
The study also showed that miR-206 promotes cancer progression in breast cancer patients and avascular
necrosis of the femoral head. Meanwhile, several studies have shown that expression levels of
miR-206 were down-regulated in laryngeal carcinoma cell multiplication, as well as in hepatocellular
carcinoma, non-small lung cancer and infantile hemangioma. Moreover, miR-206 was up-regulated in
the mild stage of amyotrophic lateral sclerosis patients and then down-regulated in the moderate and
severe stages, indicating that miR-206 has the double effects of starting and aggravating the disease. In
neuropsychiatric disorders, such as depression, miR-206 also plays an important role in the progression
of the disease; the level of miR-206 is most highly expressed in the brains of patients with depression.
In the current review, we summarize the role of miR-206 in various diseases, and miR-206 may
be developed as a new biomarker for diagnosing diseases in the near future.
