Mäestu, J, Lelle, R, Mäestu, E, Pind, R, Vahtra, E, Purge, P, and Mikulic, P. Long-term rowing performance development in male Olympic and World Championship medal winners compared with nonmedalists. J Strength Cond Res 37(9): e521–e526, 2023—The purpose of this study was, first, to investigate individual longitudinal 2,000 m rowing ergometer performance (2,000 erg) development of world class male rowers from the beginning of their career until reaching the elite level and to compare ELITE performance development with those who did not reach podium places and, second, to provide 2,000 erg milestones for talent prediction in rowing. Individual annual 2,000 erg performances of 54 male rowers were analyzed from age 15 and throughout their career. Olympic or World Championships medal winners (ELITE; n = 11) were compared with those who did not reach international podium places. Two thousand erg increased (p ≤ 0.05) until the age of 24 in ELITE, while plateaued earlier for less successful rowers. No differences in the rate of performance improvement were found between ELITE and lower performers (p > 0.05). At the age of 20, performance between ELITE and international level nonmedal winners reached significant difference (480.7 ± 20.9 W vs. 435.3 ± 33.9 W, respectively) and remained different onwards (p ≤ 0.05). However, the average of the 10 best seasons cross-sectional performances of less successful rowers were significantly higher until age 18, compared with ELITE. ELITE rowers were able to improve their 2,000 erg performance to higher age; therefore, it is difficult to predict elite performers in junior rowers. Cross-sectional performances of less successful rowers may indicate temporary high-level performers, who might not be able to advance the elite level.
The Misuse of “Workload” in Sports Science and Possible Solutions

Published: February 2023

Because of fundamental mechanical misconceptions, workload is a contested and nonsensical term that has been erroneously used in sports science literature. When the term workload is used, readers may interpret the term to mean: (a) load, referring to the weight force of an object, or an external or internal force, applied in a specified direction and, when using the International System of Units (SI), the outcome measure must be reported in newtons, or (b) the amount of work performed, which should be reported in joules. Solutions consistent with the SI and using proper scientific terminology are simple and would improve the advancement and use of knowledge in sports science. During an endurance training program, exercise duration, relative or absolute mean velocity, distance traveled, and power output are manipulated. Within strength and power training programs, variables to be considered are repetitions and sets, rest period durations, and the load lifted. In team sports, performance quantification includes displacement, distance traveled, velocity, and acceleration. These physical quantities should replace the vague and inaccurate term workload. The quantification of physical performance should be accomplished using the SI for clarity of communication and seamless use across all subdisciplines of sports science.
Low-to-Moderate Correlations Between Repeated Sprint Ability and Aerobic Capacity: A Systematic Review and Meta-analysis
Authors: Ulupınar Süleyman , Özbay Serhat , Gençoğlu Cebrail , Hazır Tahir
Published: February 2023

This systematic review and meta-analysis aims to provide meta-analytic estimates of the relationships between repeated sprint ability (RSA) outputs (total sprint time [TST] and fatigue scores) and aerobic capacity indicators (V̇O2max, the covered distance in the endurance shuttle run test [SRTdistance], and the velocity at the anaerobic lactate threshold [ALTvelocity]). To identify potential studies for inclusion, a search strategy was implemented on MEDLINE (through PubMed) and Web of Science. The correlation coefficients between RSA outputs and aerobic capacity indicators were extracted from the individual studies to reveal a pooled correlation. After the identification of studies providing inclusion criteria, 45 studies consisting of 1,488 accumulated participants were included. Meta-analysis showed the positive moderate relationships between TST and V̇O2max(pooledr= 0.444,p< 0.001), TST and SRTdistance(pooledr= 0.465,p< 0.001), TST and ALTvelocity(pooledr= 0.527,p< 0.001), RSA fatigue score and V̇O2max(pooledr= 0.449,p< 0.001), and RSA fatigue score and ALTvelocity(pooledr= 0.460,p< 0.001), which showed a low positive relationship between RSA fatigue score and SRTdistance(pooledr= 0.305,p= 0.029). This study showed pooled correlations between RSA outputs and practical aerobic capacity indicators. However, contrary to popular belief that there were stronger relationships, these relationships were low to moderate.

Authors: DeWeese Brad H. , Hamilton Dave K. , Huls Shaun , Peterson Ben J. , Rath Ted , Althoff Andrew
Published: February 2023

North American professional sport continues to evolve by adopting robust performance development strategies that place a premium on player care and competitive readiness. These strategies can be demonstrated by the increase of clubs implementing high-performance departments to maximize service quality rendered to rostered players. Although this transition to an integrated approach to player care is appreciated, it has become evident that there is a need to clarify the role, responsibilities, and job demands of high-performance directors. This emerging executive position is charged with leading complex systems of intertwined departments through the development of an environment that fosters a transdisciplinary approach to athlete preparation and care through enhanced organizational communication and the reduction of disciplinary silos that can thwart collaboration. Therefore, the current article describes the high-performance environment, allowing for a more accurate definition and representation of a modern high-performance director. The current article relies on the authors' collective experience as current professional-sport high-performance leaders to provide meaningful recommendations and insight into the field.
Absence of VGLUT3 Expression Leads to Impaired Fear Memory in Mice

Published: January 2023

Fear is an emotional mechanism that helps to cope with potential hazards. However, when fear is generalized, it becomes maladaptive and represents a core symptom of posttraumatic stress disorder (PTSD). Converging lines of research show that dysfunction of glutamatergic neurotransmission is a cardinal feature of trauma and stress related disorders such as PTSD. However, the involvement of glutamatergic co-transmission in fear is less well understood. Glutamate is accumulated into synaptic vesicles by vesicular glutamate transporters (VGLUTs). The atypical subtype, VGLUT3, is responsible for the co-transmission of glutamate with acetylcholine, serotonin, or GABA. To understand the involvement of VGLUT3-dependent co-transmission in aversive memories, we used a Pavlovian fear conditioning paradigm in VGLUT3–/–mice. Our results revealed a higher contextual fear memory in these mice, despite a facilitation of extinction. In addition, the absence of VGLUT3 leads to fear generalization, probably because of a pattern separation deficit. Our study suggests that the VGLUT3 network plays a crucial role in regulating emotional memories. Hence, VGLUT3 is a key player in the processing of aversive memories and therefore a potential therapeutic target in stress-related disorders.
Pregabalin Silences Oxaliplatin-Activated Sensory Neurons to Relieve Cold Allodynia
Authors: Iseppon Federico , Luiz Ana P. , Linley John E. , Wood John N.
Published: January 2023

Oxaliplatin is a platinum-based chemotherapeutic agent that causes cold and mechanical allodynia in up to 90% of patients. Silent Nav1.8-positive nociceptive cold sensors have been shown to be unmasked by oxaliplatin, and this event has been causally linked to the development of cold allodynia. We examined the effects of pregabalin on oxaliplatin-evoked unmasking of cold sensitive neurons using mice expressing GCaMP-3 in all sensory neurons. Intravenous injection of pregabalin significantly ameliorates cold allodynia, while decreasing the number of cold sensitive neurons by altering their excitability and temperature thresholds. The silenced neurons are predominantly medium/large mechano-cold sensitive neurons, corresponding to the “silent” cold sensors activated during neuropathy. Deletion of α2δ1 subunits abolished the effects of pregabalin on both cold allodynia and the silencing of sensory neurons. Thus, these results define a novel, peripheral inhibitory effect of pregabalin on the excitability of “silent” cold-sensing neurons in a model of oxaliplatin-dependent cold allodynia.

Published: February 2023

The photographs of Jakub Smolski constitute important documentation of the customs and habits of the Belarusian minority in Podlasie in the interwar period. Most of the photos were taken by Smolski in his home village of Łuka. The article presents the image of the peasant world of the Narew, Orthodox villages. A photographer from Łuka took pictures that showed the private world of the peasants. What was captured in the photographs proves the strength of the rites of passage, which were of great importance in the peasant community as they strengthened family and neighborhood ties. They expressed the stages of a person’s life in a specific order in a closed cycle of births, weddings and funerals. The collected photos are also an important testimony to the micro-history of the Belarusians of Podlasie. Photographs are of great value for historical, cultural and social reasons. They can be of great importance in popularizing Belarusian culture in Podlasie as an example of its strength and values, as well as in encouraging a return to its roots.

The article analyzes the structure of Ukraine’s external debt liabilities for the period from 2011 to 2021 and in the period since the beginning of the full-scale invasion. It is determined that the amount of state external liabilities, taking into account projected data, may exceed 70% of this country’s GDP, which will become the dominant form of both attracting financial resources to the state budget and threatening the state security. The authors provide an assessment of the difficulties of restructuring the external debt in terms of the specific weight of the creditor and the weight of short-term payments for the period 2022-2023. It is concluded that at the beginning of 2022, the largest specific weight in the structure of external liabilities was the debt for issued securities for foreign markets and liabilities to international financial organizations and the EU. The main payments for them fall on the third quarters of 2022 and 2023 (3.0 and 3.6 billion USD, respectively), and the payment of interest accounts for 30% of total. The article considers possible mechanisms of write-off and restructuring of the state's external debts, taking into account international experience and with regard to the crises and military conflicts. The following mechanisms for write-off and restructuring of foreign debt are analyzed: Brady Plan for debt restructuring of developing countries; and debt relief programs for the poorest countries - HIPC (heavily indebted poor countries) and MDRI (The Multilateral Debt Relief Initiative). The authors identify the guidelines of work on minimizing Ukraine's external liabilities in 2022-2023. A conclusion is made regarding the initiation of negotiations on the restructuring and write-off of the external debt burden to ease the payments on external debts, including GDP warrants. Such a task should be carried out as soon as possible before the period of the largest payments and taking into account the existing support of the governments of leading foreign countries.
Cost of credit and profitability of large industrial firms in Ukraine
Authors:   State Institution “Institute for Economics and Forecasting, NAS of Ukraine”, Kerimov Pavlo
Published: January 2023

Lending in Ukraine is usually studied from the creditor’s perspective, and based on the macroeconomic-level data, due to statistics availability. This potentially leaves out the problems that exist on microeconomic level, and leads to one-sided conclusions regarding, for instance, justification for certain levels of cost of credit based exclusively on minimal required profitability. In order to complement these conclusions, it is expedient to use microeconomic data-based analysis performed on a representative selection of firms, and thus the aim of this study is to evaluate credit availability for large firms in Ukraine in 2006-2020. Within the framework of the designated aim, liabilities structure, expected costs of financial resources, both credit and equity-based, have been analyzed for a selection of firms, and then compared to their respective profitability ratios. The main conclusion is that an average large industrial firm in Ukraine in 2006-2020 was not profitable enough to attract either loans or investments on market terms, and it is unlikely the situation has changed now. Individual firms, mainly of agricultural, mining, mechanical engineering, food and trade industries, are the exception to this rule. The reason for this is abnormally high profitability volatility, and in many cases – loss-making of large industrial firms, which in turn raise their risks (and thus the cost of financial resources for them); in other words, an average industrial firm has to pay elevated cost for credit due to its low creditworthiness. The practical conclusion is that the average large industrial firm in Ukraine is maladapted to market-based economy, and thus they should not be the centerpiece for planning of an economic development policy. Due to the tendency of such firms to bias any form of aggregated statistics in their favor, it is advisable to exclude them altogether, and aim to use representative selections based on medium and small firms instead. In particular, such approach must be used for aggregation of industry-specific capital structure, as well as for evaluation of costs of credit, equity and of their underlying risks. This would allow for setting a better scale in estimation of costs of financial resources
Two Worlds of Cultural Succession
Authors:   M. Rylskyi Institute of Art Studies, Folkloristics and Ethnology, Ponomar Liudmyla
Published: January 2023

The war of Russia against Ukraine has shown the terrorist face of the occupants, their barbaric values, the worldview of the vandals. The occupants are pursuing a strategy of destruction of Ukrainian identity and the spiritual heritage of Ukrainians. At the same time, the heroism of Ukrainian people in the struggle for independence has united the entire civilized world. The self-organization of Ukrainians in the defense of their land has assured a maturity of the civil society. This is a phenomenon of Ukrainian society, which forms an important issue for the scientists to study. Various factors explaining it are considered in the article. In the authoress opinion, positive phenomena in the development of folk culture associated with the processes of self-identification and self-determination are of the great importance in Ukraine at the beginning of the 21st century. In particular, it can be seen clearly after the materials of study of the revival of traditional clothing and the spread of folk style in everyday life, connected directly with the national raising during the Orange Revolution and the Revolution of Dignity. Folk clothing has always been an important marker of national identification, but during the war of 2014, started by Russia, the use of folk costumes becomes a manifestation of the bearers’ active stand in the national sovereignty defence. These processes show that traditional culture is one of the determining factors for the development of every society. The worldview, psychological and mental characteristics of the Russian occupants and Ukrainians are considered after the materials of Internet resources and surveys. They confirm the existence of two opposite worlds: the world of slaves and the world of free citizens. The importance of scientific research in the humanities for the refutation of the falsifications of Ukrainian cultural heritage, the direct succession of the Kyiv state, and the continuous tradition by Putin’s politicians is emphasized.

The article is dedicated to the topical issues of the state of historical and cultural heritage during the full-scale invasion of Russia on the territory of Ukraine in 2022. The problems of new realia and aspects of the research raised in the article consist in the creation of the impartial scientific analysis of the state of significant oblects of the national historical and cultural heritage by the way of study and systematization of the lost or partly ruined immovable monuments – architectural buildings of various purpose in the synthesis with the works of monumental and fine arts as well as the movable monuments – the works of decorative art in the museum collections of Ukraine during the full-scale Russian armed aggression on the territory of Ukraine in 2022. Urgent necessity of the fixation of damaged and ruined artistic monuments is explained by the exigency to raise question on the reparations and their renewal after the victory of our people in Russian-Ukrainian war.
Symbolic Factors of State Identity
Authors:   M. Rylskyi Institute of Art Studies, Folkloristics and Ethnology, Kurochkin Oleksandr
Published: January 2023

Symbolic aspects of the formation of state identity in independent Ukraine are described in the article. Post-socialist transformations of the late 20th – early 21st century in the countries of Central and Eastern Europe have been drawing increasing attention to the problems of a new state identity formation. The latter is an effect generated by the collective self-awareness of all ethnocultural communities involved in the political nation creation. In a particular context of Ukraine, the democratic institutions and values are strengthened in public life simultaneously with the overcoming of the heritage of the totalitarian past. The decommunization process has been lasting for more than a decade. Its actual results can be seen in the changed names of many settlements, squares, streets, enterprises, institutions, etc. The Leninfall is a striking indicator of the Soviet worldview matrix negotiation. It is the removal of monuments to V. Lenin and the other characters of the ideological pantheon of the USSR from the civic space. Traditional and professional cultures should be involved in a positive image of the state identity building. The system of new state holidays and rituals is aimed at the people inspiration and unification. Throughout the post-Soviet and post-socialist space the fundamental transformations of recent decades have taken place under the slogans of liberation from the totalitarian past and de-ideologization of all spheres of spiritual and social life. In post-totalitarian Ukraine the Independence Day has largely taken over the former functions of the October Revolution holiday. Neither military threats from Russia nor significant economic difficulties have prevented the bright and solemn celebration of the 30th anniversary of Ukraine Independence. This festival has become a significant indicator of the Ukrainian political nation maturity. The country has chosen the path of formation of a democratic society of the European type. The generally accepted system of holiday traditions forms the backbone of culture and spirituality of each nation. The satisfactory condition of this system influences all spheres of the general state body’s life. The task is to ensure the active importance of festive and ceremonial culture in the processes of Ukrainian independence strengthening, the political nation consolidation and establishment of the civil society with high humanistic values. The state identity of the Ukrainian nation today is at the formation stage. The ethnologists should study this process at the level of collective and individual consciousness.

The submitted study is an attempt to consider the notion of GRATITUDE in the light of the philosophical conception of H. Skovoroda, a significant figure of our culture, just today, when Ukrainian ethnos is fighting for existence, and the problem of GRATITUDE becomes even more relevant. The phenomenon of GRATITUDE is described in the scientific and cultural space as a peculiar means and opportunity for a particular person to change life qualitatively, feel the value of themselves and others. The 300th anniversary of Hryhoriy Skovoroda birthday is celebrated this year. The value of GRATITUDE for him is undeniable. A person who is satisfied with what he has is happy. The thoughts and views of the Great Ukrainian are important and necessary nowadays, because we are talking about eternal, imperishable values running up to centuries and actualize the sacred meanings in the minds of modern man. A modern view on the concept of GRATITUDE, which has appeared in the Ukrainian cultural space, namely the understanding of GRATITUDE as a memory that works is submitted in the article.

Published: January 2023

Sudden cardiac arrest (SCA) during sports events has a dramatic impact on stadium-goers and the public and is often associated with poor outcomes unless treated with an automated external defibrillator (AED). Despite this, stadiums vary in AED use. This review aims to identify the risks and incidences of SCA, and the use of AEDs in soccer and basketball stadiums. A narrative review of all relevant papers was conducted. Athletes across all sports face an SCA risk of 1:50,000 athlete-years, with the greatest risk of SCA in young male athletes (1:35,000 person-years) and black male athletes (1:18,000 person-years). Africa and South America have the poorest soccer SCA outcomes at 3% and 4% survival. AED use on-site improves survival greater than defibrillation by emergency services. Many stadiums do not have AEDs implemented into medical plans and the AEDs are often unrecognisable or are obstructed. Therefore, AEDs should be used on-site, use clear signalling, have certified trained personnel, and be incorporated into stadiums’ medical plans.

Authors: Aksu Tolga , Skeete Jamario R , Huang Henry H
Published: January 2023

As the most common sustained arrhythmia, AF is a complex clinical entity which remains a difficult condition to durably treat in the majority of patients. Over the past few decades, the management of AF has focused mainly on pulmonary vein triggers for its initiation and perpetuation. It is well known that the autonomic nervous system (ANS) has a significant role in the milieu predisposing to the triggers, perpetuators and substrate for AF. Neuromodulation of ANS – ganglionated plexus ablation, vein of Marshall ethanol infusion, transcutaneous tragal stimulation, renal nerve denervation, stellate ganglion block and baroreceptor stimulation – constitute an emerging therapeutic approach for AF. The purpose of this review is to summarise and critically appraise the currently available evidence for neuromodulation modalities in AF.

Published: January 2023

Ceramics based on zinc oxide doped with lithium was fabricated. It is shown that an increase in the lithium content in an amount up to 0.1% leads to a decrease in electrical conductivity, and then in the range up to 3% to its increase. The real and imaginary parts of the permittivity decrease with increasing lithium concentration over the entire range of measured frequencies (50 kHz - 3 MHz). Similarly, the signal of the EPR line with g-factor ~1.96 decreases. An analysis of the temperature dependence of the EPR signal intensity with a g factor of ~1.96 gives an activation energy of 0.06 eV, which practically coincides with the depth of shallow donors in ZnO. This makes it possible to identify the EPR signal with g-factor ~1.96 with oxygen vacancies.

Objective In 2011, School of Medicine, University of California, Irvine was among the first schools to implement a 4-year ultrasound curriculum. We aimed to find the point-of-care ultrasound (POCUS) utilization pattern among University of California, Irvine alumni.Methods We surveyed University of California, Irvine alumni from the class of 2011 and beyond. Survey questions included POCUS reliance, frequency of use, and comfort with image acquisition and interpretation compared with peers. The primary outcomes were self-reported comfort and reliance on POCUS.Results We received 93 responses from 624 surveyed alumni (response rate, 14.9%), of which 87 were analyzed. Although 46 respondents (52.9%) reported more reliance on POCUS, three (3.4%) relied on it less than their peers. At the same time, 72 (82.7%) and 67 (77.0%) felt more comfortable than their colleagues in obtaining and interpreting POCUS, respectively. No respondents felt less comfortable obtaining or interpreting POCUS than their peers. The frequency of POCUS use correlated directly with the frequency with which POCUS changed the responder’s case management (rho, 0.860; P<0.001). POCUS reliance also correlated with respondents’ comfort level in obtaining (rho, 0.321; P<0.001) and interpreting (rho, 0.378; P<0.001) POCUS results.Conclusion University of California, Irvine graduates had higher reliance on POCUS than peers in their respective specialties. Their POCUS findings frequently changed their case management.

Published: January 2023

In this study, matrix-assisted laser desorption ionisation time of flight mass spectrometry (MALDI-TOF MS) was used to identify bacteria from environmental matrices. The aim of this work was to determine the efficacy of this rapid technique and the bacterial community of agricultural samples. Environmental samples included the collection of irrigation waters and manures, and bacteria from the surface of vegetables were also investigated. From food safety point of view, the investigation of these microbial communities is inevitable considering their potential hazardous impact on the food production chain. Altogether 235 bacterial isolates were identified with the most frequent genera being Pseudomonas, Bacillus, Acinetobacter and Aeromonas. Our results indicated that MALDI-TOF MS can be used to identify causative agents of foodborne illnesses, food spoilage and common plant pathogens. However, limitations of the rapid identification technique were also encountered as we obtained correct identification at species level for 30.2% and at genus level for 69.8% of the isolates.

The material plays a fundamental and active role in the social lives of people, from objects like containers or buildings to food and other consumables. In this paper, evidence from absorbed residues are used to explore the contents of an Ulúa-style marble vase found in a royal courtyard at the ancient Maya site of Pacbitun in west-central Belize. Those results indicate that the vase once held concoctions containing cacao, willow and possibly vanilla. Significantly, the results also confirm residues of the important Maya ritual drink balché, in an ancient container. By placing the vase and its contents in the history of Pacbitun, we demonstrate the important role of this object and its contents in dedicatory rituals practiced in this region; we argue that subsequent disturbance of the context and the vase in antiquity points to the fragmentation of kingship.

Soil samples for microbiological analysis were taken from each variant of the experiment according to GOST 28168-89 from the upper root-inhabited horizon in the aisles and under shrubs Arónia melanocárpa, Rósa canína, Crataegus submollis, Hippophae rhamnoídes, Prúnus virginiána, Tamarix ramosissima. The most diverse communities of microorganisms were formed under the crowns of rosehip, hawthorn and cherry (16 generic complexes). The smallest number of genera was found under tamarix (12 genera) In soils with weakly occurring processes of mineralization of organic substances, imperfect fungi dominate, for which organic nitrogen is needed (Alternaria, Fusarium, etc.). The positive influence of shrubs on the microflora of the soil of recultivated objects was revealed. Saprophytic microflora prevails over pathogenic. In the experiment, the biological activity of soils containing oil sludge, according to the degree of decomposition of plant residues, depended on the growing shrubs and their organic matter. Under the crowns of Rósa canína, Prúnus virginiána and Arónia melanocárpa, it was 12.7-14.3 % higher than under the crowns of Tamarix ramosissima. It has been established that the microbiological activity of the soil increases, the process of restoring fertility and health accelerates. The greatest activity of microorganisms was detected under the crowns of rosehip, aronia, hawthorn and cherry. The leaves of these shrubs quickly turn into the organic matter of the soil, improving the conditions for the existence of soil microorganisms. Plantings of shrubs create phytomeliorative protection for grasses, which form a sufficiently large phytomass of leaves and stems (9.14 c/ha) at the end of the growing season. The resulting organic matter is nutrition for the microflora and contributes to the restoration of soil fertility.

The article presents the results of the analysis of the spatial-temporal dynamics of wildfires within the boundaries of the economic region “Mekong Delta” in the south-west of the Republic of Vietnam for the period from 2001-2020. according to various information products of satellite monitoring based on data MODIS spatial resolution 250-1000 m and Landsat resolution 30 m. Mapping of burnt-out areas was performed and the recurrence of fires was determined for 13 provinces of the Mekong Delta. In the future, this will allow us to determine the influence of natural and anthropogenic factors on the burnability of the territory, as well as to study the consequences of pyrogenic effects on landscapes. According to various information products of the burnt areas, the total area of the hares ranged from 1 to 8.7 million hectares or from 15 to 37 % of the entire territory. Data on the recurrence of fires during the study period were obtained, which allows us to find out in which areas fires occur most often. The maximum frequency of fires is typical for Anjiang Province, located in the north of the region. The ability to harvest rice 2-3 times a year creates prerequisites for burning rice straw in the fields. This is probably why the increased frequency of fires and the burning of the most agricultural-developed provinces of the Mekong Delta are associated with this. This indicates the high importance of fires as an exogenous factor for the ecosystems of the lower Mekong in the conditions of climate change. In the future, an analysis of the dynamics of the territory’s burnability under the influence of climatic and hydrological factors may be carried out, considering the peculiarities of agricultural use of the Mekong Delta territory.

The asexual form of Ophiocordyceps sinensis has been controversial, but various morphologic mycelium appeared when O. sinensis was cultured under experimental conditions. To explore the generation mechanism of morphologic mycelium, developmental transcriptomes were analyzed from three kinds of mycelium (aerial mycelium, hyphae knot, and substrate mycelium). The results showed that diameter and morphology of these three kinds of mycelium were obviously different. KEGG functional enrichment analysis showed that the differential expressed genes (DEGs) of substrate mycelium were enriched in ribosomes and peroxisomes, indicating that prophase culture was rich in nutrients and the metabolism of substrate mycelium cells was vigorous in the stage of nutrient absorption. The up-DEGs of hyphae knot were mainly enriched in the oxidative phosphorylation pathway, indicating that oxidative phosphorylation was the main energy source for mycelium formation in the stage of nutrient accumulation and reproductive transformation. The up-DEGs of aerial mycelium were mainly enriched in the synthesis and degradation pathways of valine, leucine, and isoleucine, suggesting that the occurrence of aerial mycelium was related to amino acid metabolism at the later stage of culture, and nutritional stress accelerated the reproduction of asexual spores. In addition, the important roles of mycelium formation related genes were verified by combined analysis of qRT-PCR and transcriptome sequencing. Collectively, this study will provide theoretical guidance for inhibiting the occurrence of aerogenous mycelium and promoting the development of mycelium into pinhead primordia in the culture of O. sinensis in the future.

Glioma is the most common tumor of the central nervous system (CNS). Drug resistance, and lack of effective treatment methods make the treatment effect of glioma patients unsatisfactory. The recent discovery of cuproptosis has led to new thinking about the therapeutic and prognostic targets of glioma. The transcripts and clinical data of glioma samples were obtained from The cancer genome atlas (TCGA). The cuproptosis-related lncRNA (CRL)-based glioma prognostic models were built through least absolute shrinkage and selection operator (LASSO) regression analysis in the train set and validated in the test set. Kaplan-Meier survival curve, risk curve analysis, and time-dependent receiver operating characteristic (ROC) curve were used to assess the predictive ability and risk differentiation ability of the models. Univariate and multivariate COX regression analyses were conducted on the models and various clinical features, and then nomograms were constructed to verify their predictive efficacy and accuracy. Finally, we explored potential associations of the models with immune function, drug sensitivity, and the tumor mutational burden of glioma. Four CRLs were selected from the training set of 255 LGG samples and the other four CRLs were selected from the training set of 79 GBM samples to construct the models. Follow-up analysis showed that the models have commendable prognostic value and accuracy for glioma. Notably, the models were also associated with the immune function, drug sensitivity, and tumor mutational burden of gliomas. Our study showed that CRLs were prognostic biomarkers of glioma, closely related to glioma immune function. CRLs may affect uniquely the sensitivity of glioma treatment. It will be a potential therapeutic target for glioma. CRLs will offer new perspectives on the prognosis and therapy of gliomas.

Published: January 2023

La presente guía práctica brinda recomendaciones para orientar la fase inicial del proceso enfermero: la valoración, con una estructuración de la entrevista de enfermería a la persona en el contexto familiar. La valoración establece un proceso planificado y sistemático de recopilación de datos subjetivos y objetivos, con la aplicación de instrumentos validados (escalas, test, entre otros), que conduce posteriormente a la interpretación de la información del estado de salud del sujeto de cuidado para la toma de decisiones en la elaboración de planes de cuidados con enfoque hacia la respuesta humana integral y global ante una necesidad del sujeto de cuidado. La Valoración por Patrones Funcionales de Marjory Gordon aporta una serie de primacías al proceso: pueden ser manejadas independientemente del modelo enfermero que se sigue, se integran de forma apropiada al ámbito de la atención primaria de salud y permiten estructurar y ordenar los datos de la valoración, funcionan para cualquier sujeto de cuidado: individuo a lo largo del ciclo vital, familia o comunidad, en situaciones de salud o enfermedad, y facilitan el tránsito a la siguiente fase de diagnóstico enfermero al contrastar con el origen de la clasificación por dominios de la NANDA. El objetivo de esta guía radica en ofrecer a los estudiantes del programa de enfermería conocimientos de los procesos y las herramientas que pueden ser utilizadas para la valoración de enfermería, dirigido a la familia y a la persona, fundamental en el contexto de la atención primaria.
