Aim. To estimate the level of cardiac biomarkers and metalloproteinases (MMPs) in breast cancer patient’s plasma 12 months after the end of chemotherapy (CT) with doxorubicin. To determine the relationship between changes in their level and the occurrence of early cardiotoxicity (CT) taking into account arterial hypertension (AH) and the prescription of cardiotropic therapy (CTT). Materials and methods. The study involved patients with a confirmed diagnosis of breast cancer. Before and 12 months after the end of chemotherapy, the level of MMPs and cardiac markers in blood plasma were determined using the enzyme immunoassay method. Results. A statistically significant increase in the level of cardiac troponins (TnI, TnT) and a decrease in NT-proBNP in the CT+ and CT- subgroups 12 months after the end of chemotherapy with doxorubicin were revealed. Differences between CT+ and CT- were detected only for TnI hs (2.8 times, p = 0.011). In the KTT+ subgroup, no statistically significant differences were observed between the level of the studied parameters in KT+ and KT-. The differences identified without taking into account CTT remained in the subgroup of CTT- patients. The level of TnI hs in patients KT+ and KTT+ was lower (median 6.7 pg/ml) compared to KT+ and KTT- (median 16.8 pg/ml). An increase in the level of MMP-2 and a decrease in MMP-9 and MMP-3 were observed in patients in the CT+ and CT- subgroups. The median values of MMP-3 level in the CT+ subgroup were statistically significantly lower than those in the CT- subgroup by 16.6% (p = 0.021). In CTT+ there were no statistically significant differences between the level of MMP in CT+ and CT-, but in CTT- the level of MMP-3 was statistically significantly different in the subgroups CT+ and CT-. There was no relationship between the level of MMP and hypertension before the start of chemotherapy. Conclusion. An increase in TnI hs level and a decrease in plasma MMP-3 level 12 months after the end of chemotherapy has the potential to detect early signs of CT. The sensitivity and specificity of potential markers increase in patient groups not receiving CTT. It was confirmed that there was no connection between the presence of hypertension in patients, the level of all biochemical parameters included in the study and CT.
Development and preliminary testing of a temporally controllable weather modification rocket with spatial seeding capacity
Authors: Dong Xiaobo , Wang Xiaoqing , Liu Yongde , Wang Xiaorong
Published: September 2024

Abstract. Current weather modification rockets with a single operation mode, limited operating height, and fixed and uncontrollable operating time cannot achieve seeding in different layers, stages, and quantities for different cloud systems. Therefore, a temporally controllable weather modification rocket with spatial seeding capability is developed in this study. This new rocket features an electronic fuse-controlled intelligent ignition system, with eight channels of ignition tube outputs. Additionally, carrier wave communication technology is incorporated to set the seeding time for eight sets of ignition tubes. The temporally controllable rocket is capable of initiating seeding within 2–26 s and can conduct operations for layering, arbitrary altitude, and fractional-dose seeding within the altitude range of 500–5500 m (at a launch angle of 70°), which is calculated based on the flight trajectory of rockets. The minimum time interval of the rocket for seeding can be set to 0.1 s, and all 48 catalyst bullets loaded in a single rocket can be launched within 0.8 s. Thus, the rocket can achieve both concentrated and continuous seeding. Consequently, during weather modification operations, the parameters such as altitude, thickness, and operating temperature of target clouds can be obtained through detection, and they can be used to automatically calculate the suitable seeding time, seeding altitude, and seeding dose by the launch control system based on the flight trajectory of rockets to improve the accuracy and scientificity of cloud catalytic operations. Ground tests show that the reliabilities of the electric ignition tube output, new electronic fuse input and output, and electronic fuse output energy all meet the design specification. The temporally controllable spatial seeding rocket can achieve adjustable and controllable seeding times for catalytic bullets, meeting the safety and reliability requirements of rockets.
The impact of bedrock meander cutoffs on 50 kyr scale incision rates, San Juan River, Utah

Published: September 2024

Abstract. Incision rates of major rivers may reflect the effects of drainage reorganization, hillslope processes, tectonic uplift, climate, the properties of rocks into which rivers incise, and other autogenic processes. On the Colorado Plateau, incision rates along the Colorado River have been interpreted as resulting from abrupt base-level changes produced by the integration of the Colorado River system. Specifically, the integration of the Colorado River in the location of Grand Canyon is thought to have created a knickpoint, enhanced by lithologic contrasts, which is propagating upstream. While evidence exists for a < 1 Ma acceleration of incision on parts of the Colorado River, uncertainty about the processes reflected in shorter-term incision rates muddies comparison with longer-term averages. In this work, we combine a cosmogenic radionuclide depth profile exposure age and post-infrared infrared stimulated luminescence (p-IR IRSL) to date fluvial deposits adjacent to the San Juan River, a major tributary of the Colorado River, near Mexican Hat, Utah. The deposits, resting on a 27 m strath surface, are constrained to be ∼ 28–40 ka, suggesting an incision rate of 678–968 m Myr−1, which is a factor of 7 higher than the long-term rate of ∼ 125 m Myr−1 over the past ∼ 1.2 Myr. We observe fluvial deposits that were abandoned due to a bedrock meander cutoff, which partially explains our accelerated incision rate. We use a simple geometric model, informed by our field data, to demonstrate how planform river evolution may, in some circumstances, increase short-term incision rates relative to long-term averages. These short-term rates may reflect a combination of autocyclic and climatic processes, which limits their ability to resolve longer-term changes in incision rates that may be related to changes in base level or tectonics.

Abstract. Stream water chemistry at catchment outlets is commonly used to infer flow paths of water through catchments and to quantify the relative contributions of various flow paths and/or end-members, especially during storm events. For this purpose, the number and nature of these flow paths or end-members are commonly determined with principal component analysis based on all available conservative solute data in inverse end-member mixing analyses (EMMAs). However, apart from the selection of conservative solutes, little attention is paid to the number and choice of the solutes that are included in the analysis, despite the impact this choice can have on the interpretation of the results from an inverse EMMA. Here, we propose a methodology that tries to fill this gap. For a given pair of measured solutes, the proposed methodology determines the minimum number of required end-members, based on the synchronous variation of the solutes during storm events. This allows identification of solute pairs for which a simple two-end-member mixing model is sufficient to explain their variation during storm events and of solute pairs, which show a more complex pattern requiring a higher-order end-member mixing model. We analyse the concentration–concentration relationships of several major ion pairs on the storm-event scale, using multi-year, high-frequency (< 60 min) monitoring data from the outlet of two small (0.8 to 5 km2) French catchments with contrasting land use, climate, and geology. A large number of storm events (56 % to 79 %) could be interpreted as being the result of a mixture of only two end-members, depending on the catchment and the ion pairs used. Even though some of these results could have been expected (e.g. a two-end-member model for the Na+/Cl- pair in a catchment close to the Atlantic coast), others were more surprising and in contrast to previous studies. These findings might help to revise or improve perceptual catchment understanding of flow path or end-member contributions and of biogeochemical processes. In addition, this methodology can identify which solute pairs are governed by identical hydro-biogeochemical processes and which solutes are modified by more complex and diverse processes.

Published: September 2024

Abstract. The severe changes in climate resulting in the polar oceans getting warmer – with drastic consequences to their physical, biogeochemical and biological state – require forecasting systems that can accurately simulate and skilfully predict the state of the ice cover and its temporal evolution. Sea-ice processes significantly impact ocean circulation, water mass formation and modifications, and air-sea fluxes. They comprise vertical processes, mainly related to thermodynamics, and horizontal ones, due to internal sea ice mechanics and motion. We provide an overview on how these processes can be modelled and how operational systems are working, in combination with data assimilation techniques, to enhance accuracy and reliability. We also emphasize the need for advancing research on improving such numerical techniques by highlighting currents limits and ways forward.

Authors: Azevedo Daniel Abreu de , Ribeiro Rafael Winter
Published: September 2024

Na história da geografia é possível identificar diferentes modalidades de contato direto com o espaço objeto de estudo ou ensino, cujas potencialidades, virtudes e problemas diferem entre si. O objetivo desse artigo é distinguir os usos ao longo do tempo de três modalidades fundamentais de contato do geógrafo com o terreno, quais sejam: excursões, expedições e trabalho de campo, posicionando-as em suas virtudes na construção do conhecimento geográfico. Argumentamos que ao longo do tempo no Brasil houve um esvaziamento dessas nuances, o que produziu uma perda na formação dos profissionais da área. A partir de uma recuperação histórica dos usos de cada uma dessas modalidades na prática da geografia brasileira, buscamos identificar suas diferenças e enfatizar o potencial de suas aplicações. Realizar essa discussão vai além de uma simples diferenciação semântica, já que possuem potencialidades para o fazer do geógrafo e do professor de geografia que precisam ser exploradas.

Introduction: The neutrophil/lymphocyte ratio (NLR) and the platelet/lymphocyte ratio (PLR) are markers of inflammation and prognosis in systemic diseases. This study determined the association between hematological indices, and disease activity in patients with systemic lupus erythematosus (SLE). Methods: This prospective, observational and analytical cross-sectional study included 87 Paraguayan patients diagnosed with SLE, according to the ACR/EULAR 2019 criteria. We investigate four hematological indices: neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), eosinophil/lymphocyte ratio (ELR), and monocytes/lymphocyte ratio (MLR). Results: Eighty-seven percent were female, with a median age of 34.9 ±12.3 years. SLEDAI mean of 3.68 ± 4.76 was found. SLEDAI mean was 3.68 ± 4.76. Positivity of anti-DNAds was found in 52% of the patients. CRP mean was 3.5 ± 4.6. Regarding values of hematological indices, we found: NLR mean of 2.4 ± 1.6 was obtained, ELR 0.07 ± 0.09, MRL 0.07 ± 0.07 and PLR 155.89 ± 80.69. A significant positive correlation was found with SLEDAI and NLR (r=0.34, p=0.001). Based on the ROC curve, the best cut-off value for our patient cohort capable of predicting patients with high activity is for NLR values ? 2.283 (AUC: 0.66). Conclusion: NLR could be a valuable and accessible biomarker to identify elevated activity in patients with SLE.

Published: September 2024

Introduction: Prevention of diabetes requires sustained lifestyle changes as well as identification of groups at higher risk. Objective: The aim of this research was to estimate the risk of diabetes in vulnerable subjects from a primary care center in northern Argentina, with no known glucose abnormalities, using the FINDRISC questionnaire, investigate the relationship between survey variables and the final score, and explore its association with metabolic risk factors and body composition. Methodology: This cross-sectional design included 498 patients without type 2 diabetes or known glycemic abnormalities. All subjects underwent a complete medical history and completed the FINDRISC questionnaire. Results: The predominant age group was 18-45 years old. Around 64% were physically active and 44% reported daily consumption of fruit and vegetables. Most of them had a BMI higher than 25 kg/m2. Regarding the risk of developing type 2 diabetes in the next 10 years, 24.3% were at low risk and the remaining fraction was distributed in slightly elevated, moderate, high and very high risk. All variables influenced the individuals' variance (p < 0.05). The hierarchical clustering and principal component analysis (PCA) revealed that elevated FINDRISC score was strongly associated with: age > 65 years, fasting blood glucose, BMI ? 30 kg/m2 and antihypertensives use. CONCLUTION: We found a high percentage of obesity and overweight, as well as a high risk of cardiometabolic disease and of developing T2D.  In addition, in the population studied, the variables that compose the FINDRISC did not influence the highest score in the same way.

Published: September 2024

Introduction: Frailty and depression risk are common in older adults undergoing chronic obstructive pulmonary disease (COPD) treatment. However, little is known about this association in people with COPD residing in low- and middle-income countries. Objective: The study aimed to establish the relationship between frailty and depression among ambulatory adults over 60 years with COPD in Santa Marta, Colombia. Methodology: A cross-sectional study was designed in which consecutive patients from the pulmonology outpatient clinic were invited to participate. Frailty was quantified with the FiND (Frail Non-Disabled [FiND] Screening Tool) [Cronbach's alpha 0.65] and depression with the Primary Care Screening Questionnaire for Depression (PSQD) [Cronbach's alpha 0.73]. Results: Three-hundred forty-nine patients with COPD between 60 and 98 years participated (M=75.6, SD=8.4), 61.9% were males, and 19.8% presented a C or D combined evaluation. Two hundred eighty-six patients (76.8%) presented frailty with and without mobility disability, and 31.2% presented depression. The relationship of frailty with depression remained significant, even after adjusting for confounding variables (OR=2.80, 95%CI 1.42-5.51). Conclusions: Frailty and depression are significantly associated after adjusting for confounding variables. More studies are welcome.
Indicadores bibliométricos de Medicina Clínica y Social
Authors: Barrios Iván
Published: September 2024

Estimados lectores y autores, Medicina Clínica y Social inició su vida académica en el año 2017, y a lo largo de estos años ha logrado varios hitos en cuanto a indexación a bases de datos nacionales, regionales y globales de alto impacto. Iniciando con DOAJ en 2020, SciELO Paraguay en 2021, Redalyc en 2022 con calificación de excelente, culminando con su ingreso a SCOPUS en 2023, un hito histórico al ser la primera revista paraguaya en ingresar a esta prestigiosa base de datos global y luego de un año de su ingreso ya contamos con un cuartil dentro de SCIMAGO, siendo la única revista Q4 en Paraguay hasta la fecha (1).
Analicemos lo que presentó SCIMAGO durante el periodo 2019-2023 de la revista. En primer lugar, se encuentra en la posición 59 a nivel latinoamericano en la categoría de medicina (miscelánea) con un SJR de 0,12, un índice H de 3, 78 artículos y 18 citas (0,18 citas por documento) (2). Esto nos presenta un reto en términos de mejorar considerablemente las citas que podemos recibir en SCOPUS, ya que, si hacemos un análisis más amplio en Google Académico, nos encontramos con otro escenario donde hay un mayor número de citas a nivel global.
Antes de proceder con el análisis bibliométrico general, presentaré la definición de SJR. SJR es un indicador de prestigio independiente del tamaño que clasifica a las revistas en función de su “prestigio promedio por artículo”. Se basa en la idea de que “no todas las citas son iguales”. SJR es una medida de la influencia científica de las revistas, que considera tanto el número de citas que recibe una revista como la importancia o prestigio de las revistas de donde provienen dichas citas. Mide la influencia científica del artículo promedio de una revista y expresa cuán central es el artículo promedio de una revista para las discusiones científicas globales (1).
Por esta razón, podemos encontrar más artículos y citas fuera de SCIMAGO mirando los datos brutos en SCOPUS. Después de unirse a SCOPUS, se reportaron 168 artículos que recibieron 92 citas en total, con un promedio de 18,4 citas por año y 0,55 citas por artículo, asumiendo un índice H de 4. Esto también cambia si consideramos los artículos citados según Google Académico (que recopila citas de más recursos y no se limita a artículos de revistas científicas).
Considerando Google Académico, hay 222 artículos publicados desde 2017 hasta 2024, con un total de 937 citas (896 en los últimos cinco años) con un índice H de 17 (16 en los últimos cinco años) (3). Los esfuerzos deben centrarse en mejorar la colaboración internacional, mejorando así el impacto en las revistas de impacto para mejorar el cuartil y la calidad de nuestros esfuerzos editoriales.

EFFECTS OF COLOUR OF CULTURE FACILITY (TARPAULIN) ON GROWTH PERFORMANCE & SURVIVAL OF Clarias gariepinus
Authors: Osayi S. E. , Okonji V. A.
Published: September 2024

It is important to note if the different colours of tarpaulin used for culture have effect on the growth performance and survival of Clarias gariepinus. The study was carried out in faculty of Agric cooperative farms located at Evboneka, Ovia North East local government area, Edo state. The research was designed as a factorial experiment made up of 3 colours of tarpaulin tanks (black, yellow and brown) x 18 weeks culture period in CRD. Each treatment replicated trice. Thus a total of nine culture units was used. The experimental unit was made up of 3 black, 3 brown and 3 yellow tarpaulin tanks each measuring 4x5m2. 2700 post fingerlings that is, 300 post fingerlings/tank were bought from a reputable hatchery and cultured for 18 weeks under semi-intensive system (10 fish/m2). The yellow tarpaulin tank had the highest mean weight (283.21g) followed by the black tarpaulin tank (247.964g) and brown tarpaulin tanks (249.42g) (P.<0.05)). The result also showed that fishes in yellow tanks had better FCR of 1.220) followed by brown tanks with 1.236 and black tarpaulin tanks with 1.251 as FCR. However, percentage survival was slightly higher in Black tanks (89.63), followed by the brown (89.30) and the lowest in the yellow tanks (88.86). This study showed that colour of culture facility may slightly affect fish growth and yield.  Yellow tarpaulin tank appears to be brighter in colour and had relatively higher weight gain and is therefore recommended for C gariepinus culture over other tank colours (Black and brown).
Beyond MHD
Authors: Balsara Dinshaw Sarosh
Published: September 2024

The MHD equations have served plasma physicists, space physicists and astrophysicists very well for the past several decades. Even so, one comes to the realization that the MHD equations are only an approximation that applies to systems where the collision rate between charged particles is fast enough to rapidly restore isotropy in the pressure tensor. For many systems involving collisionless plasmas, this assumption of the isotropy of the pressure tensor is invalid. In such situations, the Chew Goldberger and Low equations take over. They are based on a double adiabatic approximation and allow the pressure parallel to the field lines to differ from the pressure perpendicular to the field lines. While the CGL equations are well-formed, they have resisted numerical solution for a very long time. The reason is that if these equations are taken by themselves, they could potentially give rise to an unbounded increase in pressure anisotropy in certain circumstances. This unbounded increase in anisotropy can eventually result in a loss of hyperbolicity and a consequent code crash.

Real world systems, like the solar wind, show that there are limits to the pressure anisotropy. Therefore, to make sense of the CGL equations, and their physical import, one has to understand the plasma physics effects, such as the mirror instability and firehose instability, which restore pressure isotropy at a microphysical level. Folding in these physical effects also results in numerical challenges that have to be overcome. In this talk we show how the CGL equations can be made numerically tractable by a deft combination of physical reasoning and advanced numerical methods. Preliminary applications will also be presented.

Multiple criterion decision-making (MCDM) has been widely utilized in everyday life in variousways, with countless success stories aiding in the analysis of complicated problems and the provision of anaccurate decision process. To date, MCDM remains the best strategy to provide the finest solutions to solvecomplex problems in the field of specialized systems. Even so, several challenges faced MCDM approaches, asmentioned in academic literature. The most significant challenges are uncertainty and ambiguity. The fuzzydecision by opinion score method (FDOSM) is one of the most recent MCDM methods. Consequently, the purposeof this study was to examine and assess publications regarding the various types of developments of FDOSM inrecent years and to collect the essential literature findings. Fundamentally, based on systematic review protocol,the searching process was conducted across four major databases, including IEEE Xplore (IEEE), ScienceDirect(SD), Scopus, and PubMed from the date of publishing of FDOSM article, based on particular Query "(MCDM OR'Multi-criteria decision-making') AND (FDOSM OR 'Fuzzy decision by opinion score method') AND (Fuzzy)AND ('development method' OR 'developing'). The data collection process started on 23 August 2023 and endedon 30 October 2023, which included several scientific studies related to development FDOSM across several fuzzytypes. These indexes are considered extensive and dependable enough to have the scope of our literature review.A final set of articles, n=22, was selected depended on predefined inclusion and exclusion criteria for this study.A coherent classification for current studies has been formed according to the development of FDOSM based on anew extension of a fuzzy set. Other aspects, such as the research method followed, the protocol adopted by thesystematic review, and demographic statistics of the literature distribution, were included. Exciting patterns wereobserved, which were compiled and analyzed in tabular format according to their importance. The results of thisliterature systematic review provide a precise summary of each recent development concerning the FDOSM and itsuse, including: 1- Extracting the development types employed in the FDOSM method, 2- Extracting aggregationoperator types, 3- Integration Method with FDOSM (hybrid with other methods), and 4- Case study types showinghow FDOSM approaches may help decision-makers in numerous decisions. Finally, this study highlights researchopportunities and encourages current and future efforts to better comprehend this field.

Published: September 2024

The paper investigates the strength properties of polyolefins (LDPE and HDPE) filled with highly dispersed zeolite
particles. It has been found that an increase in the filler content leads to an increase in tensile stress at rupture.
The heterogeneity manifests itself in the destruction of all standard injection molding samples without exception during
stretching in the part of the working area that is as far away from the gate as possible. The reasons for the rupture,
the decrease in strength and the uneven tensile strength along the length of the injection molding samples are
explained.
TECHNOLOGY OF DIFFUSION SATURATION
AND HEAT TREATMENT OF WIRE
BY ELECTROCONTACT CYCLIC HEATING
Authors: SEMENCHENKO M.
Published: September 2024

An installation for diffusion saturation and heat treatment of wire by electrocontact cyclic heating is proposed.
The equipment allows processing by continuous and stepwise wire feeding. The installation allows processing with
a pulse duration and a pause duration of 0,01 seconds – 999 minutes. Allows you to set the current strength at a maximum
value of 100 A and select the voltage value from the range of 3–32 V. The speed of movement of the wire
in the processing area in the basic version is 10 cm/min. The influence of the fractional composition of the saturating
medium on the course of the diffusion saturation of the wire has been studied. It is recommended to use a saturating
medium with a particle size of 63–160 microns for borating steel wire. A method is proposed for optimizing the modes
of diffusion saturation and heat treatment of wire when changing the diameter of the wire, the chemical composition
of the wire material and the saturating medium, and the processing time.

The terminology and classification of pedestrian mobility devices participating in road traffic are considered.
It is proposed and substantiated to consider in the legal field a means of individual mobility - a personal mobility device
as a controlled self-propelled object (in the case of equipment with an electric motor with a power of no more than
250 W), used to move a pedestrian participating in road traffic at a speed of no more than 12 km / h, while it creates an
increased probability of causing injury due to the impossibility of full control over it by the pedestrian.

Tüm bireyler için serbest zaman aktivitelerine katılım sağladığı faydalar açısından oldukça önemlidir. Üniversite kampüsleri ise sahip oldukları fiziksel ve sosyal imkânlar açısından önemli bir serbest zaman aktivite ortamı olarak görülmektedir. Bu imkânlardan yararlanmak, katılımın artması ve şartların iyileştirilmesi her üniversite öğrencisinin olduğu gibi özel gereksinimli öğrenciler için de oldukça önemlidir. Bu kapsamda, araştırmanın amacı aynı üniversitede öğrenim görmekte olan 11 özel gereksinimli üniversite öğrencisinin kampüs içi serbest zaman aktivitelerine katılımlarını etkileyen faktörlerin sosyo-ekolojik modele göre incelenmesidir. Araştırma, nitel araştırma modeli ve fenomenolojik desende tasarlanmıştır. Araştırmanın teorik çerçevesini ise sosyo-ekolojik model oluşturmaktadır. Araştırmada çalışma grubu amaçlı örnekleme yöntemlerinden ölçüt örnekleme yöntemi ile seçilmiştir. Verilerin analizinde ise içerik analizi yöntemi kullanılmıştır. Yapılan analizler sonucunda, sosyo-ekolojik model doğrultusunda özel gereksinimli üniversite öğrencilerinin kampüs içi serbest zaman aktivitelerine katılımlarında etkili olan engeller ve kolaylaştırıcı faktörler belirlenmiştir. Modelin ilk aşaması olan kişisel faktörler incelendiğinde, özel gereksinimli öğrencilerin ‘negatif tutumları’ ve ‘yükümlülükleri’ birer engel, ‘pozitif tutumları’ ise kolaylaştırıcı olarak görülmektedir. Kişilerarası faktörlerde ‘istenmeyen durumlar’ birer engel, ‘destek’ ise kolaylaştırıcıdır. Çevresel faktörlerde engeller ‘yetersizlikler’, kolaylaştırıcılar ise ‘fırsatlar’ olarak karşımıza çıkmaktadır. Modelin son aşaması olan kurumsal faktörlerde ise ‘kurumun negatif yaklaşımı’ bir engel olarak görülürken, ‘kurumun pozitif yaklaşımı’ ise kolaylaştırıcı rolündedir. Sonuç olarak, özel gereksinimli üniversite öğrencilerinin kampüs içi serbest zaman aktivitelerine katılımının gerçekleştiği ancak bu süreçte pek çok farklı engel ile karşılaştıkları tespit edilmiştir. Araştırma sonucunda en fazla engelin çevresel faktörlerden kaynaklandığı, en fazla kolaylaştırıcının ise kurumsal faktörlerden oluştuğu görülmektedir.
