An integrated intelligent approach for solving geometric design problems is studied. A general optimization placement problem of arbitrary shaped objects in a bounded container is formulated as a mathematical programming problem in terms of the phi-function technique. Various technological requirements (geometric and mechanical) are considered, including continuous translations and rotations of the objects, allowable distances between objects, prohibited zones in the container, balancing conditions, mechanical strength constraints. Solution strategies, methods, and algorithms to solve different variants of the model are discussed and illustrated with examples.

Published: April 2023

The article is devoted to the analysis of existing methods of searching for explosive objects on the surface of the earth and under it, and to the development of new effective approaches to solving the problem. We focus on developing solutions based on AI technologies and methods that use publicly available hardware, structural methods, and machine learning methods The problems and their solutions mentioned in the article are quite specific and, despite the relevance of the topic of searching for explosive objects, poorly developed. The main reason for this situation is either the lack of information in the public domain, when developments are carried out by military departments or private companies, or the relatively low development of countries that suffer from the problem of demining territories where military operations have been or are being conducted. From 2014 to 2022, on the territory of Ukraine, the area affected by explosive objects was approximately equal to the area of Croatia, which took 20 years to clear the territories after the war in the Balkans (1991–1995). After 2022, the territory affected by explosive objects increased several times. The intensity of shelling can currently be compared to the First and Second World Wars, so it is safe to say that the problem of finding explosive objects has reached a higher level. Therefore, considering the volume of data and the scale of the affected territories, we decided to study the main directions and modern methods of searching and classifying explosive objects in order to use them to create a system or a framework for solving the given task. The results of this article are planned to be used to create a single algorithmic environment for solving the problems of finding explosive objects, which, if necessary, will be able to process data from different sources of information, with different degrees of detail and depth.

Published: April 2023

The paper for the parallel model of computation, a modification of the method of implementing the multiplication of multi-digit integers based on the fast Fourier transform (FFT) avoiding the bit-reversed ordering is proposed. The paper researches the calculation of FFT according to the “butterfly” scheme based on decimation-in- frequency and decimation-in-time methods, an input signal with elements in direct and bit-reversed order, with an increase and decrease in the number Fourier series coefficients at each step of the "butterfly", the use of a list of Fourier series coefficients in direct and bit-reversed order. The standard FFT-based multiplication algorithm uses the same “butterfly” operation to compute the forward and inverse Fourier transforms. The paper analyzes two combinations of the FFTFDN–FFTTBN and FFTFBN–FFTTDN “butterfly” calculation schemes for calculating forward and inverse discrete Fourier transforms (DFT) in the case of implementing the multi-digit operation in parallel computational model to exclude bit-reversed permutation. A scheme for distributing calculations among four processors is proposed, in which forward and inverse Fourier transform calculations are localized within one parallel processor. The proposed modification does not reduce the computational complexity in terms of the number of complex operations, but due to the exclusion of bit-reversed permutation, the number of synchronization commands between processors and data is reduced, which reduces the algorithm execution time. The scheme can be adapted to distribute the computations among a larger number of processors. Four algorithms for implementing FFT based on decimation-in-frequency and decimation-in-time methods, an input vector with elements in direct and bit-reversed orders are presented. To check the result of the calculation, the algorithm of multiplication avoiding the steps of bit-reversed ordering was implemented in the APL programming language. An example of calculation is given in the form of a table.

Published: April 2023

The article examines the technology of data mining as an instrumental means of automating decision-making support in automated troop management systems (ATMS). During the study of the subject area, the problems of the decision-making support process in ATMSs have been analyzed, sources testifying to the relevance of the automation of this process and the current state of affairs are being considered. An option to increase the degree of automation of the decision-making support process is proposed for consideration due to the use of intelligent data analysis technology, which has been the main focus of the article. During the analysis of the latest research and publications on this topic, it has been found that the automation of the decision-making support process due to intelligent data analysis is considered promising and is studied, as a rule, within the framework of research on artificial intelligence and machine learning technologies. The main material of the study covers the generalized algorithm of automated decision-making support, an analogy of the functions of the intelligent decision support system with the tasks solved by intelligent data analysis is also made. Based on this, the clustering tasks have been described, search for associative rules, classification and regression in the context of their application for getting knowledge from data found in the automated troop management system, with examples of the results of their implementation. A more in-depth study of intellectual data analysis is defined as directions for further research and ways to automate the decision-making support process using this technology. Also, a promising direction of research is simulation modeling of an intellectualized decision support system of an automated troops control system.

Authors:   Sumy State University, Ukraine, K Hrabina , V Shendryk ,   Sumy State University, Ukraine
Published: April 2023

The study is devoted to the formation of an intelligent model for choosing and applying the optimal strategy for managing risk events, both threats and opportunities, of modern small IT projects with limited resources and implicit or uncertain influencing factors. The proposed model is built taking into account the decomposition of the process into three sub-processes, for which the criteria, target function, graphs of the development of events are proposed, taking into account the synergy of possible threats and opportunities. It is formed for the purpose of proactive management of risk events and is able to overcome uncertainty due to possible forecasting of future states for cases of a priori uncertainty and lack of information about possible consequences. The distribution of threats and opportunities is applied in the form of a developed unique target model with introduced weights of threats and opportunities based on expert assessments, taking into account the experience of experts from previous typical projects. Theoretical recommendations and risk management standards from the most common project management standards are taken into account. The developed intellectual model takes into account both the cost of implementing strategies and the total costs of their implementation.

This article investigates the species of the family Sargassaceae present in Kuwait, analyzing nuclear ribosomal internal transcribed spacer 2 (ITS2) sequences of 67 individuals collected in 2018–2020. Morphological characterization and DNA barcoding confirmed the presence of eight taxa that belong to Sargassaceae. Five species belong to the genus Sargassum, while three other taxa, namely Sirophysalis trinodis, Hormophysa cuneiformis, and Polycladia myrica, belong to other genera. For the latter species, there was no ITS2 sequence available so far. As for Sargassum species, previous records based on phenotypic identifications were only confirmed for a minority of species. Based on 100% sequence identity with records from other regions, we recognize S. aquifolium, S. ilicifolium var. acaraeocarpum, S. yinggehaiense, and one still unclear species (Sargassum sp.). According to the sequences, the fifth and most common Sargassum species in Kuwait, previously identified as S. asperifolium, is S. carpophyllum. However, the ITS2 sequence of this entity did not show a perfect match with any S. carpophyllum specimen so far sequenced. The comparatively limited diversity of Sargassum in Kuwait may be due to the prevailing extreme environmental conditions, in particular large temperature amplitude between +14 °C in winter and +37 °C in summer.

This is the second article in a series of critical revisions of the species composition of powdery mildew fungi (Erysiphaceae, Helotiales, Ascomycota) of Ukraine and their distribution within the country. The first article of the series dealt with the small genera Arthrocladiella and Blumeria, while here we consider species of the Erysiphe sect. Erysiphe. Representatives of the other two sections of this genus, Microsphaera and Uncinula, will be critically examined in further publications. In the present article, a list of 24 species of the section Erysiphe recorded in Ukraine, their distribution by regions of Ukraine, and a key for their identification are provided. The most common species frequently occurring in many regions of Ukraine are E. aquilegiae, E. convolvuli, E. cruciferarum, E. heraclei, E. pisi, and E. polygoni. Such species as E. buhrii, E. howeana, E. knautiae, E. limonii, E. lycopsidis, and E. urticae were recorded less often. Erysiphe betae, E. circaeae, E. lythri, E. macleayae, E. mayori, E. thesii, and E. ulmariae are relatively rare species that occurred infrequently in several regions. Erysiphe caricae, E. catalpae, E. caulicola, E. celosiae, and E. malvae are known each from one or a few localities only. A number of species are invasive fungi, most of them have been recorded in Ukraine relatively recently, within the last hundred years. These are E. betae, E. caricae, E. catalpae, E. celosiae, E. howeana, and E. macleayae.

Published: April 2023

Based on the methods of transverse transects and phytoindication, results of the analysis of ecological and cenotic status of the Dokuchaev shelterbelts and their extremities are provided. A combination of various ecological conditions characterizing formation of vegetation cover in the protective shelterbelts is demonstrated. The current state of plant communities of the forest strips is described. A regionally rare plant species in Kirovohrad Region, Convallaria majalis, is reported. It was established that the investigated shelterbelts were formed under forest-meadow and forest-steppe conditions. The analysis of coenotic features of all studied shelterbelts has proved that they have similar species composition and communities structure. The Dokuchaev windbreaks and shelterbelts need further monitoring of changes in their plantation structure, distribution and introduction of new plant species, as well as ecological and sanitary conditions.

Published: April 2023

Three new for Ukraine species, Anema tumidulum, A. nodulosum, and Pyrenocarpon thelostomum (Lichinales, Lichinaceae), are reported. They were found in the Dnister Canyon, on the S and W exposed cliff surfaces where water tracks formed 'a black zone' of the Collematetea cristati class. Other species forming these communities are Anema decipiens, Psorotichia schaereri, Peccania coralloides, Thallinocarpon nigritellum, Thyrea confusa, and Verrucaria nigrescens s. l. The analyzed dataset included three relevés from the Dnister cliff, as well as 14 relevés from literature sources: seven relevés of Peccanio coralloidis-Thyreetum pulvinatae recorded from Poland, and seven relevés of Thyrea nigritella-Anema moedlingense comm. from the Czech Republic. These data were analyzed in JUICE software. All analyzed relevés were separated in two clusters. Three relevés from Dnister Canyon fell into the same cluster with Thyrea nigritella – Anema moelingensis comm. provided by Wirth in 1972. We consider these communities as a new association Thallinocarpo nigritelli-Anemum tumidulae. Diagnostic species of the association are Thallinocarpon nigritellum, Anema tumidulum, Staurothele frustulenta, and Anema nodulosum. The lectotype of Peccanio coralloidis-Thyreetum pulvinatae has been proposed, with diagnostic species Enchylium polycarpon, Leproplaca cirrochroa, Placidium rufescens, Placynthium nigrum, Toninia candida, and Synalissa symphorea. These associations belong to the Peccanion coralloidis alliance and differ by their ecological preferences. The association Peccanio coralloidis-Thyreetum pulvinatae represents the nomenclatural type of the alliance and includes communities on the vertical exposed limestone surfaces in water tracks. The Thallinocarpo nigritelli-Anemum tumidulae association occupies similar habitats but in the xeric geollitoral zone along river banks. The alliance Peccanion coralloidis and order Collematetalia cristati are reported from Ukraine for the first time.
Between Inside and Outside

Our everyday routines and movements are entangled with and guided by our interactions with material things, such as the material things displayed in our neighbors’ windows. During the pandemic we were unable to engage with others in the street, and so what we shared of ourselves through our windows was a form of communication with our neighbors, even when we could not see them. In this time of social distancing, these archaeological moments are particularly meaningful. This paper explores our deep enmeshment and entanglement with the material displays in our neighbors’ windows, and how these displays contribute to a poetics of place.

La uia noua o vía XVIII del Itinerario de Antonino tiene origen en época flavia y establece la conexión directa entre dos capitales del extremo de la Hispania citerior: Bracara Augusta y Asturica Augusta. Uno de los aspectos más impactantes en relación con esta vía, teniendo en cuenta que no tiene raíces en época de Augusto, es el gran número de miliarios que le están asociados, lo que la coloca entre las que poseen mayor densidad de estos soportes epigráficos en todo el imperio. Se estudian dos miliarios recuperados, en la década de 1990, en las millas XXX y XXXI a Bracara Augusta, ubicadas en la sierra de Gerês (Terras de Bouro, Braga, Portugal), atribuibles a los hijos de Constantino I, haciéndose asimismo la revisión de un tercero, de Maximino y Máximo, relativo a la primera de estas millas y de descubrimiento más reciente. Una particularidad de uno de estos miliarios inéditos es el hecho de que conserva restos de pintura asociada a la inscripción. Se hace el estudio epigráfico completo, también con enfoque al significado de estos soportes en el contexto paisajístico local.

Published: April 2023

2’-Hydroxychalcones and murrayafoline A, a natural compounds isolated from Glycomis stenocarpa, have been reported to have the promising anti-cancer activity. In this study, a series of 2'-hydroxychalcones containing murrayafoline A (MuA) 6a-f were achieved by Claisen-Schmidt condensation of the key intermediate 5'-(1-methoxy-3-methyl-carbazolyl)methyl-2'-hydroxyacetophenone 4 with various aldehydes 5a-f with purpose of combining activity of two precusors. Their structures were determined by NMR and MS spectral data. Screening for cytotoxicity of compounds showed that compounds 6a-6d expressed cytotoxic activity, notably compound 6a displayed activity against all tested cell lines LU-1, Hep-G2, MCF-7, P338, and SW480 with the IC50 values ranging from 23.97 to 80.19 μg/mL. Clearly, the substitution at position of N-H group of murrayafoline a led to a decline in the cytotoxicity of the obtained derivatives. This finding suggests the presence of the N-H group might be play a crucial role for the cytotoxicity of the murrayafoline A derivatives.
Image compression in all-optical domain using one 6×6 multimode interference coupler
Authors: Thuy Bui Thi , Le Trung Thanh
Published: April 2023

We present a new method for image compression using the Haar wavelet transform (HWT) in all-optical domain. The proposed architecture is based on the optical Haar wavelet transform using only one 6×6 multimode interference (MMI) coupler. By locating the positions of input and output waveguides and optimizing design length of the MMI, the expected matrix of the Haar transform is obtained. The new hardware architecture is suitable for directly integrating with digital cameras for image processing. The processing of images therefore is at very high speed. Our method can also be applied to data compression in big data analytics. Our structure can provide a large fabrication tolerance which is compatible with the CMOS existing technology. Our simulations show that the length variation of ± 2 µm still keeps the output powers unchanged. We have simulate successfully the use of the proposed HWT to compress cameraman image with the compressed ratios of 20, 30, 50 % with MSE and PSNR from 0.1 - 0.3 and 62 – 67 dB, respectively.

Knema pachycarpa is a native tree distributed in central provinces of Viet Nam. Until now, only few chemical studies of Knema species in Viet Nam have been reported. Phytochemical study of Knema pachycarpa leaves led to the isolation of seven known compounds including six flavonoids 5,7,3′-trihydroxy-5′-methoxy isoflavone (1), luteolin (2), (-)-narigenin (3), (+)-catechin (4), isoquercetrin (5), and nicotiflorin (6), and a biphenyl compound  3,3',4,4'-tetrahydroxybiphenyl (7). Their structures were elucidated by MS and NMR data analysis and compared with those previously reported. Compounds 3 and 6-7 were found from Knema genus for the first time. In the cytotoxic assay, biphenyl compound (7) exhibited strong cytotoxicity to KB cancer cell line with IC50 value of 2.38 ± 0.11 mg/mL. Compound 7 also displayed showed activity against HepG2, Lu and MCF7 cancer cell lines with IC50 ranges from 18.25 ± 0.92 mg/mL to 35.56 ± 1.17 mg/mL, whereas flavonoids 1-6 were weakly active or inactive against tested cell lines.
Electromagnetic heating using nanomaterials and various potentials applications
Authors: Phuc Nguyen Xuan , Do Hung Manh  , Pham Hong Nam
Published: April 2023

Electromagnetic heating (EMH) is a process of adsorbing electromagnetic wave energy by a material and converting it into heat. Nanomaterials can serve as novel susceptors in EMH due to the fine size that made them become heat sources from inside, as well as because of new heating mechanisms such as Neel relaxation by magnetic nanoparticles (MNPs) and localized surface plasmon resonance by metallic nanostructures. This review firstly introduces general theoretical & experimental aspects of the alternating electric field (AEF)- and magnetic field (AMF)-stimulated heating. Next, attempts to fabricate MNPs and photothermal nanoparticles (PNPs) of improved heating efficiencies have been reviewed and those with the highest specific loss power have been summarized. Finally, potential applications, including cancer treatment using AMF@MNP hyperthermia and AEF@PNP hyperthermia, AMF@MNP- and AEF@PNP- triggered drug release, as well as nanocomposite processing were particularly highlighted. Besides, other exotic applications such as toxic solvent desorption from adsorbent materials, thermophoresis in precise membrane melting as well as optical signal processing in heat-assisted magnetic memory technology were also outlined. The various applications were attempted to represent into 2 groups: biomedicine, and materials processing; which are composed of localized/targeted and volumetric heating type.

Authors:   ,   Linnaeus University, Wireklint Sara
Published: April 2023

Aim: The overall aim was to explore Emergency Department triage in Swedenthrough a specific focus on the Swedish triage system, RETTS© and RegisteredNurses’ experience of triage. Methods: Study I was a cross-sectional, prospective, national survey. Fiftyone(75%) EDs completed a digital questionnaire about triage and triage relatedwork. Study II was longitudinal, retrospective, register-based. In total 74,845patient ED visits were extracted, two annual cohorts from two EDs. Study IIIwas cross-sectional, 28 RNs from two EDs allocated triage levels on 46authentic patient scenarios. Study IV was descriptive, inductive, based on semistructuredinterviews with 14 RNs representing different parts of Sweden andlevels of hospitals. Descriptive (I, II, III), inferential (II), kappa statics (III), andinductive content analyses (IV) were applied. Results: Triage is firmly implemented in Swedish EDs and the Swedish triagesystem, RETTS© is the most commonly applied system but with variation on howRETTS© is applied or taught. RETTS© demonstrated no statistically significantdifference between the annual upgrades regarding ten-day and 72-hour mortality,but for admission to intensive care unit (ICU). Statistically significant differencewas demonstrated for mortality when data was adjusted for gender, age andcomorbidity. There was a statistically significant difference between the triagelevels for all outcomes. An inability to distinguish between stable/unstable patientwas demonstrated when 21/46 scenarios were triaged over this boundary. RETTS©reliability was moderate with κ=0.562. Furthermore, the RNs experience of triagewas described as A Balancing Act of an Ambiguous Assignment, a movementbetween uncomplicated and complex assessments performed with visible andimplicit prerequisites and in time perspectives that is both unpredictable andpredictable. Conclusion: Triage is performed in the majority of Swedish EDs and RETTS© isthe most commonly applied triage system, however, without a unanimous approach.The annual upgrade of RETTS© do not improve the ability to identify risk for shorttermmortality, but for admission to ICU. Furthermore, RETTS© reliability wasmoderate, and the RNs considered triage as a balancing act, a performance that hasto result in a safe assessment of the patient’s needs.
Hvordan det kan ha seg at noen på operasjonsstuen ikke bruker munnbind?
Authors: Fjell Kristiansen Elin Helene , Boge Jeanne Helene
Published: April 2023

Denne artikkelen er basert på en studie om bruk av munnbind ved kirurgiske inngrep.
Bakgrunnen for studien var førsteforfatters observasjoner og undringer over at det ved noen operasjoner bare var operasjonssykepleiere og kirurger som agerte i operasjonsområdet som brukte munnbind. Det var spesielt anestesipersonell som ikke brukte munnbind. For å finne ut om det kunne være historiske forklaringer på at nåtidige munnbindpraktikker ved kirurgiske inngrep er som de er, ble det gjennomført praxeologiske analyser av norske lærebøker i sykepleie fra 1877-2018. Analysene er fundert i Bourdieus teori om praktisk sans og en praxeologisk analysestrategi.
Analysene viser at fra 1921 til 1954 har norske lærebøker i sykepleie argumentert for at de som står i operasjonsfeltet bør bruke munnbind. Det var sannsynligvis ikke tilfeldig at argumentasjonen for bruk av munnbind oppstod i 1921, ettersom at spanskesyken tok livet av 13 000-15 000 nordmenn i perioden 1918-1919.
Fra 1955 og frem til vår tid har det vært argumentert for at alle som agerer på operasjonsstuen bør bruke munnbind. Men det er forståelig at anestesipersonell kan la være å bruke munnbind selv om de dermed bryter retningslinjene og agerer heterodoxt. Dette ettersom at slikt personell ikke er utsatt for blodsøl fra operasjonspasientene, og det er liten sjanse for at sekret fra deres munn og nese vil havne i pasientens operasjonssår og forårsake infeksjoner. Det kan også være at de bygger sine praktikker på forskning, da det i liten grad finnes studier som viser evidens for at munnbind bruk blant personalet som ikke står i operasjonsfeltet, reduserer de postoperative infeksjonsratene.

Published: April 2023

ABSTRACT Objectives: This study was designed to investigate the possible relationship between the anatomical location of the PFF (head-neck fractures) and the demographic features, comorbidities, and risk factors of elderly patients. Methods: 233 patients aged 65 years and over, who were admitted to the emergency department with a diagnosis of proximal femur fracture were included in this study. Results: Most patients (59.6%) had a trochanteric fracture. The incidence of trochanteric fractures had a statistically significant positive correlation with age. Falls at ground level were found to be highly associated with trochanteric fractures (92,8%). At least one complication was observed in 57 (41,0%) cases and 31 (22,3%) died in one year, of the patients with trochanteric fractures. Comorbidity was not related to fracture location statistically. Fall ground level (p = 0.013), complication rate (73.7%; p <0.001), and Charlesen comorbidity index (p = 0.019) were statistically significantly associated with death. The logistic regression analysis of variables determined that only the quantity of comorbidities may be related to femoral neck fractures (p = 0.047). Conclusion: Female patients with trochanteric fractures were found to be older than male patients. Fall ground level, mortality, and complications were more frequently seen in patients with trochanteric fractures. Level of Evidence II, Retrospective study.

ABSTRACT Objectives: Evaluate the efficacy and effects of releasing the muscles of subluxated hips of patients with SCZ. Methods: This is a retrospective study with 29 patients with subluxation of the hip, corresponding to 55 hips operated in a public hospital in Recife, Brazil. Preoperative femoral head migration (PM) percentages were evaluated and compared with 6- and 12-month postoperative results. Results: Twenty-nine patients were eligible, representing 55 hips evaluated. 19 were female (65.5%), with a mean age of 31.45 months (ranging from 23 to 42 years). 19 patients were GMFCS level V (65.5%), 34.5% were level IV, and 20 of the 29 patients (69%) had no complications. The PM had an absolute reduction of 11.6% (GMFCS IV) and 13.31% (GMFCS V) in the first six months. After 12 months, there was a regression of MP of 7.14% (GMFCS V) and 11.25% (GMFCS IV) compared to preoperative values, with no significant statistical difference among MP values presented between 6 and 12 months after surgery. Conclusions: The surgery was effective in PM regression during the analyzed period and presented a low complication rate. Level of Evidence III; Comparative retrospective study.
THE CEMENTED DOUBLE MOBILITY CUP IN HIP REVISION: DIFFERENT POSSIBILITIES OF USE
Authors: de Cano Jaime José Morales , Trias Estela
Published: April 2023

ABSTRACT Introduction: The aim of our work is to review those patients who underwent prosthetic hip revision surgery in our hospital considered to be patients at high risk of dislocation or recurrent dislocation, and who underwent a double mobility cemented cup (CMD). Analyzing the different ways to place these cups and the clinical results and reluxations. Material and methods: The 69 cases comprised 34 men and 35 women with a mean age of 77,39 years. The mean follow-up was 4.7536 years. The type of intervention performed varied according to the cause of the intervention, the acetabular bone stock and the state of the primary cup. In the cases in which there was a good fixation of the primary metalback, we opted to carry out a cementation of the cemented DMC into the existing well-fixed metal acetabular shell, this occurred in 23 cases. In the cases where there was loosening of the primary cup but there was a good bone stock, a CMD was cemented into the bone (21 cases). In the cases where there was a Paprosky type III we cemented a DMC to a Bursch-Schneider reinforcement ring together with the placement of a cancellous bone graft (25 cases). Results: The clinical evaluation at the end of the follow-up, according to the MD Scale, showed the mean value was 16.454 (SD 0.79472), with a survival at the end of the follow-up of 100% of the placed DMC. Conclusion: The use of cemented DMC is a good solution in the replacement of THA, especially in cases of reluxation or risk of dislocation due to personal or technical predisposing factors. The use of these DMC cemented can be directly to the bone, into the existing well-fixed metal Shell, or cemented to a reinforcing ring, depending on the acetabular defect.

ABSTRACT Introduction: Marathon running requires stretching practices to relieve fatigue after exercise. The Proprioceptive Neuromuscular Facilitation (PNF) technique is an advanced stretching technique that allows segmenting of a specific muscle group for simultaneous stretching and strengthening. Objective: This paper explores the effect of PNF stretching exercise on relieving sports fatigue after marathon races. Methods: In this paper, 160 marathon runners were selected for the experiment, and randomly divided into experimental and control groups. The experimental group performed the PNF stretching exercise, while the control group remained with traditional stretching without any new intervention. Fatigue was assessed according to the heart rate, collected before, during, and after the experiment. Results: After nine weeks of PNF stretching training, the heart rate in the experimental group changed from 65.35 to 62.46 in the morning; during training, the group’s heart rate changed from 180.79 to 173.04; after recovery, the first group’s heart rate changed from 82.88 to 81.88. In the control group, the heart rate of the group also showed changes from 65.29 to 68.86 in the morning; during training, it changed from 180.7 to 175.49; and after recovery, from 86.23 to 88.4. Conclusion: PNF stretching exercise has a positive effect on relieving sports fatigue after marathon races. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

Authors: Santi P.R. , França M.R. , Milistetd M.
Published: April 2023

ABSTRACT Immunomediated thrombocytopenia is a systemic metabolic disorder in which the platelet count falls below reference values, as the patient's immune system destroys them. The main clinical signs in thrombocytopenia are petechial, hemorrhages, ecchymoses and suffusions. Hematomas can also occur in coagulation disorders. The diagnosis is based on clinical findings and hematological examinations. The treatment consists of the use of corticosteroids and immunosuppressants, delaying cell destruction, and may last for months, not always obtaining a cure for the disease. The present work reports the use of therapy with allogeneic mesenchymal stem cells, derived from the adipose tissue of dogs, for the treatment of chronic immunomediated thrombocytopenia, with an evolution of more than one year, in a Pinscher dog. The alternative treatment showed a good evolution, keeping platelets within the reference values during the treatment, giving the patient quality of life and removing the need for continuous medication for homeostasis after treatment.

ABSTRACT The objective was to evaluate the supplementation of fat-soluble and water-soluble vitamins on the performance and plasma concentrations of vitamins in modern hybrids pigs. A total of 144 commercial hybrid castrated male, 43.531 ± 1.099kg, were used in a randomized block design with six treatments, eight replicates and three animals per pen. The experimental treatments were different vitamin supplementation levels - 0, 25, 50, 75, 100, and 125% of the recommended by Rostagno et al. (2011) for male pigs in growth I (40 to 50kg), growth II (50 to 70kg), and finishing I (70 to 90kg) phases. For growth phases I and II, a linear effect (P<0.05) due to increase in vitamin supplementation was observed on performance. For finishing phase I and total phase, a linear effect (P<0.05) was observed with increased final average weight (FAW) and improved feed conversion ratio (FCR). For average daily weight gain (ADWG) and average daily feed intake (ADFI) a quadratic effect was observed (P<0.05). A linear (P<0.05) increase in plasmatic α-tocopherol and B12 was observed with the 125%. Thus, it is concluded that the 125% vitamin supplementation improved performance of modern hybrids pigs (40 to 90kg).
