Published: August 2024

The article continues to consider problem of regulation of pharmaceuticals turn-over in the EU and the USA in 1992–2020. The history of development of European pharmaceutical legislation in 1992–2001 is considered. This stage is characterized by passing Directives (laws of indirect action) that were obligatory for implementation through their inclusion into national normative legal bases. In 2001 the passed laws were compiled into EU Pharmaceutical Code (Directive 2001/83) that regulates main sections of pharmaceuticals turn-over from their production to pharmaceutical control. The adoption of Code laid the foundation for EU legislation in the field of medications.

Endogenous Aggregate Beliefs: Equity Trading under Heterogeneity in Ambiguity Aversion
Authors: Alonso Irasema , Prado Mauricio
Published: August 2024

We build a simple and tractable model of consumer heterogeneity in ambiguity aversion and use it to illustrate how asymmetric beliefs in the asset markets affect the dynamics of asset pricing, portfolio allocation, and the wealth distribution. The model is an otherwise canonical exchange-economy setting with two aggregate states of nature and two assets. The key focus is on how asset prices, when subjected to ambiguity, behave very differently in the short run than in the long run. In the short run, heterogeneity plays an important role. In the long run, belief heterogeneity persists, but the wealth distribution has evolved so that only the least ambiguity-averse investors matter for prices. As part of the short-run dynamics, the model can generate endogenous aggregate movements in non-participation—a drastic form of trading less—in response to ambiguity, with strong depressing effects on asset prices.

Authors: Ahn Sanghyuk , Baik Daniel Jinhag , Kim Seung-Hyun
Published: August 2024

Purpose: To evaluate the surgical outcomes of a modified normogram for bilateral lateral rectus recession in the surgical management of intermittent exotropia, with a focus on achieving small overcorrection.Methods: A retrospective medical chart review of 242 patients who underwent surgery for intermittent exotropia between October 2014 and June 2020 was performed. Our modified normogram reducing amount of recession targeted for small postoperative overcorrection within 5 prism diopters (PD). Patients were observed for at least 3 years. Esodeviation was denoted by negative numbers and positive values indicated exodeviation. A satisfactory outcome was defined as if distant angle of deviation ranged between ≤10 PD of exotropia and ≤5 PD of esotropia. Recurrence was defined as an exodeviation of >10 PD at distance. Overcorrection was defined as an esodeviation of >5 PD at distance.Results: The mean preoperative deviation angles were 29.32 ± 3.92 PD at distance and 29.88 ± 4.41 PD at near. At postoperative day 1, the mean deviation angles at distance and near were –6.22 ± 1.44 and –6.22 ± 1.49 PD, respectively. Overcorrection within 6 PD of esodeviation was seen in 168 patients (69.42%), undercorrection with exophoria was noted in 11 patients (4.55%), and overcorrection by more than 6 PD of esodeviation was seen in 63 patients (26.03%) at postoperative day 1. The long-term success rate at postoperative 3 years was 77.27% (187 of 242), with a recurrence rate of 19.83% (48 of 242) and an overcorrection rate of 2.89% (7 of 242). A positive correlation between the angle of deviation at postoperative day 1 and 3 years was observed (r = 0.22, p = 0.001). The final success rate at the final examination after a mean follow-up of 38.60 ± 7.99 months was 83.06%.Conclusions: Our modified normogram for bilateral lateral rectus recession in intermittent exotropia surgery resulted in successful surgical outcomes with small overcorrection, reducing the risk of consecutive esotropia due to excessive overcorrection.
EVALUATING THE ROLE OF MELATONIN ON THYROID PHYSIOLOGY AND DISEASES
Authors: Öztürk Ceylan Özlem , Yılmaz Beyza , Süzen Sibel
Published: August 2024

Objective: Melatonin (MLT) is largely produced within the pinealocytes from tryptophan, happening during the dark. MLT’s binding sites have been established in numerous parts of the brain but also in the cells of the immune system, gonads, kidney, and cardiovascular system. MLT may directly or indirectly affect the thyroid gland and its activities. It can also prevent thyroid cell proliferation and interfere with thyroid hormone synthesis. The underlying mechanisms need to be carefully interpreted.
Result and Discussion: In this review the typical inhibitory effects of MLT on the thyroid gland and hormone secretion, as well as its antioxidant effects and relationship with thyroid diseases is investigated.
Energy costs of the sponge pump
Authors: Riisgård HU , Larsen PS
Published: August 2024

Sponges pump large volumes of water to obtain nutrition from a dilute suspension of food particles and dissolved organic matter. Our review of the literature shows pumping power ranging from 0.85% up to 28% of the total metabolic respiration rate Rtot, where the pumping power (Pp = pumping rate × pump pressure) is the energy per unit time transferred to the water flow. Some published values of pumping costs are high while others are low due to incorrect estimates of some pressure losses in the aquiferous system of sponges. However, as improved descriptions of detailed structures and function, especially of the filter apparatus of the choanocytes, have become available, our corrected values for pressure losses show the respiration-specific pumping costs of Pp/Rtot = 1.3 to 22%. The stated pumping cost is based on the minimal (theoretical) pump power delivered to the water, which excludes a mechanical efficiency of pump action and a metabolic efficiency that expresses the fraction of total metabolism that is devoted to driving the pump action, considerations that should be included in future studies.
Hemodynamic Mechanisms Initiating Salt-Sensitive Hypertension in Rat Model of Primary Aldosteronism
Authors: Pravenec M , Mlejnek P , Šimáková M , Šilhavý J
Published: August 2024

Few studies have investigated the hemodynamic mechanism whereby primary hyperaldosteronism causes hypertension. The traditional view holds that hyperaldosteronism initiates hypertension by amplifying salt-dependent increases in cardiac output (CO) by promoting increases in sodium retention and blood volume. Systemic vascular resistance (SVR) is said to increase only as a secondary consequence of the increased CO and blood pressure. Recently, we investigated the primary hemodynamic mechanism whereby hyperaldosteronism promotes salt sensitivity and initiation of salt-dependent hypertension. In unilaterally nephrectomized male Sprague-Dawley rats given infusions of aldosterone or vehicle, we found that aldosterone promoted salt sensitivity and initiation of salt-dependent hypertension by amplifying salt-induced increases in SVR while decreasing CO. In addition, we validated mathematical models of human integrative physiology, derived from Guyton’s classic 1972 model - Quantitative Cardiovascular Physiology-2005 and HumMod-3.0.4. Neither model accurately predicted the usual changes in sodium balance, CO, and SVR that normally occur in response to clinically realistic increases in salt intake. These results demonstrate significant limitations with the hypotheses inherent in the Guyton models. Together these findings challenge the traditional view of the hemodynamic mechanisms that cause salt-sensitive hypertension in primary aldosteronism.

Published: August 2024

In 2023 six decades have elapsed since the first experimental work on the heart muscle was published, in which a member of the Institute of Physiology of the Czech Academy of Sciences participated as an author; Professor Otakar Poupa was the founder and protagonist of this research domain. Sixty years – more than half of the century – is certainly significant enough anniversary that is worth looking back and reflecting on what was achieved during sometimes very complicated periods of life. It represents the history of an entire generation of experimental cardiologists; it is possible to learn from its successes and mistakes. The objective of this review is to succinctly illuminate the scientific trajectory of an experimental cardiological department over a 60-year span, from its inaugural publication to the present. The old truth – historia magistra vitae – is still valid.
Czech Footprints in the Bioenergetics Research

Published: August 2024

Life manifests as growth, movement or heat production that occurs thanks to the energy accepted from the outside environment. The basis of energy transduction attracted the Czech researchers since the beginning of the 20th century. It further accelerated after World War II, when the new Institute of Physiology was established in 1954. When it was found that energy is stored in the form of adenosine triphosphate (ATP) that can be used by numerous reactions as energy source and is produced in the process called oxidative phosphorylation localized in mitochondria, the investigation focused on this cellular organelle. Although the Czech scientists had to overcome various obstacles including Communist party leadership, driven by curiosity, boldness, and enthusiasm, they characterized broad spectrum of mitochondrial properties in different tissues in (patho)physiological conditions in collaboration with many world-known laboratories. The current review summarizes the contribution of the Czech scientists to the bioenergetic and mitochondrial research in the global context.

Academic democracy has no single meaning. Because of this theoretical problem, when it is applied in state administration, things happen that are not the same between one country and another. However, in fact, in this understanding of democracy there are values that are universal. These values can be used as a minimum measure of whether a country consistently implements the principles of democracy or not. This means that these values are a condition for whether a country adheres to a democratic system or not.Keywords: Democracy, Power.

INTRODUCTION: Accessible spaceflight may seem a distant concept. As part of a diverse European Space Agency funded Topical Team, we are working on the physiological feasibility of space missions being undertaken by people with physical disabilities. Here, the first activity of this team is presented in the form of key lessons learned from aviation to inform new work on space missions.

DISCUSSION: The first lesson is agreeing on realistic expectations about impairments, their severity, and the possibility of flying independently. This is important in terms of astronaut recruitment and societal expectations. The second lesson relates to training and adjustments for people with disabilities. Flexibility is important while maintaining safety for everyone involved. The third lesson is about managing unconscious bias from the different stakeholders. We conclude by arguing that engagement with people from different backgrounds is essential for the success of the first space mission with people with physical disabilities.

The Impact of Machine Learning on Future Defense Strategies
Authors: Sarjito Aris
Published: August 2024

Abstract:
Machine learning (ML) is increasingly pivotal in shaping future defense strategies, offering advancements across critical domains such as cybersecurity, resource allocation, and autonomous systems. This research explores the multifaceted impact of ML in defense, focusing on three primary areas: enhancing threat detection and mitigation in cybersecurity, optimizing resource allocation and logistics in military operations, and navigating the ethical and strategic implications of autonomous defense systems. The study utilizes qualitative research methods, particularly through secondary data analysis from government reports, academic publications, industry white papers, and ethical frameworks. Findings indicate that ML algorithms significantly bolster threat detection by leveraging Anomaly Detection Theory and Game Theory, thereby enhancing responsiveness to cyber threats. In military logistics, ML models informed by Operations Research and Supply Chain Management Theory optimize resource distribution, improve operational efficiencies, and support mission readiness. Ethically, the deployment of ML in autonomous defense systems prompts considerations of moral responsibilities, biases, and strategic risks, necessitating comprehensive governance frameworks. In conclusion, while ML offers transformative potential in defense strategies, effective implementation requires robust ethical guidelines, strategic foresight, and interdisciplinary collaboration to mitigate risks and maximize benefits.

Reconhece-se que a compreensão gradual da construção do conhecimento científico inclui a valorização do erro como parte do processo. O estudo também apresenta o ILC como indicador para políticas públicas, revelando que a maioria dos alunos brasileiros se encontram nos níveis Rudimentar e Básico de LC, indicando conhecimentos científicos elementares. Destaca-se a necessidade de formação contínua para que os professores superem o estágio intermediário de LC, no qual as discussões se limitam ao nível das possibilidades, revelando insegurança e forte dependência dos teóricos. Ao promover o LC não apenas como habilidades acadêmicas, mas como um elemento fundamental para construir uma sociedade consciente, participativa e justa, a formação docente possibilita o desenvolvimento crítico e autônomo do LC dos alunos, promovendo uma educação mais eficaz.

Published: August 2024

Grass represents a major renewable feedstock in temperate climate zones, but its efficient utilization is challenging in biorefineries and advanced biofuels due to its structural recalcitrance. Here hydrothermal hydrolysis (100–180°C, for up to 40 min duration) was investigated to improve sugar yields from grass silage. The optimal conditions (140°C for 20 min duration) showed the highest sugar yield of 0.29 g/g volatile solid (VS) of grass silage. Further increasing the temperature to 180°C favored degradation of sugars (such as glucose, xylose) to by-products (such as furfural, hydroxymethylfurfural). A first-order reaction model confirmed a two-step reaction with the first step hydrolysis and the second step degradation. An energy balance calculation indicated that pre-treatment at 140°C required an energy input of 16.5 kJ/g VS, which could be significantly reduced to 5.1 kJ/g VS through efficient heat recovery. This research assists in understanding of the hydrolysis mechanism and provides a practical solution to produce grass-based sugars for further advanced biofuel and biorefinery applications.

With the increasing demand for the refined management of residential loads, the study of the non-invasive load monitoring (NILM) technologies has attracted much attention in recent years. This paper proposes a novel method of residential load identification based on load feature matrix and improved neural networks. Firstly, it constructs a unified scale bitmap format gray image consisted of multiple load feature matrix including: V-I characteristic curve, 1–16 harmonic currents, 1-cycle steady-state current waveform, maximum and minimum current values, active and reactive power. Secondly, it adopts a convolutional layer to extract image features and performs further feature extraction through a convolutional block attention module (CBAM). Thirdly, the feature matrix is converted and input to a bidirectional long short-term memory (BiLSTM) for training and identification. Furthermore, the identification results are optimized with dynamic time warping (DTW). The effectiveness of the proposed method is verified by the commonly used PLAID database.

The objective of this study is to analyze environmental genetic selection signals in large-scale sheep populations with conflicting environmental adaptations, aiming to identify and isolate genes associated with environmental adaptations in sheep populations. Kirghiz sheep, which inhabit high-altitude environments year-round, demonstrate the ability to adapt to extreme conditions. In this study, 42 Kirghiz sheep, 24 Tien-Shan in Kyrgyzstan sheep, 189 Qira black sheep, and 160 Chinese Merino sheep were genotyped using Illumina Ovine SNP50K chip. Regions exhibiting a selection signal threshold of 5%, as well as PI analysis and haplotype statistical scanning gene data were annotated, and intersecting genes were identified as candidate genes. Through Fst and haplotype statistical analysis revealed the key gene PDGFD and its vicinity’s impact on fat deposition in sheep tails. Additionally, Fst and PI analysis uncovered genes related to high-altitude adaptation as well as those linked to animal growth and reproduction.Further GO and KEGG enrichment pathway analyses unveiled pathways associated with high-altitude adaptation such as negative regulation of peptidyl-tyrosine phosphorylation and xenobiotic metabolism processes.This investigation into the adaptability of Kirghiz sheep provides theoretical support and practical guidance for the conservation and genetic enhancement of Kirghiz sheep germplasm resources.

Introduction

Gluten quality is one of the most important traits of the common wheat (Triticum aestivum L.). In Chinese wheat production, Yannong series cultivars/derivative lines possess unique characteristics and play an important role in both yield and quality contribution.

Methods

To dissect their genetic basis of the gluten quality, in this study, allelic variations of high-molecular-weight glutenin subunit (HMW-GS) and low-molecular-weight glutenin subunit (LMW-GS) in 30 Yannong series wheat cultivars/derivative lines and three check cultivars were evaluated using the allele-specific molecular markers, and six crucial quality indexes were also further measured and analyzed.

Results

The results demonstrated that the frequencies of HMW-GSs By8, Dx5+Dy10 and Dx5+Dy10+Dy12 in these 30 genotypes and three check cultivars accounted for 87.9%, 24.2% and 9.1%, respectively. For the allelic variations of LMW-GSs, Glu-A3a, Glu-A3b, Glu-A3c, Glu-A3f, and Glu-A3g were identified in 18, 9, 13, 11, and 2 genotypes, respectively; Glu-B3d, Glu-B3g and Glu-B3f were identified in 13, 23 and 4 genotypes, respectively. Notably, Yannong 999, containing By8 + Dx5 + Dy10, and Jinan 17 containing By8 + Dy12 both meet the national standard for high-quality wheat and belong to the category of first-class high-quality strong gluten wheat.

Discussion

These findings can provide reference for wheat quality improvement and popularization in the production.
