Investigation of the halo effect in the evolution of a nonstationary disk of spiral galaxies
Authors: Mannapova Kamola Alimdjanovna , Mirtadjieva Karamat Taxirovna 
Published: June 2023

Abstract
In this article, we consider the problem of the evolution of the disk subsystem of galaxies, taking into account their halos. The global structure of the disk of galaxies strongly depends on the mass and shape of the halo. To this end, we have studied the evolution of nonradial oscillations of a nonstationary disk surrounded by a passive ellipsoidal halo with a uniform density. A system of equations for the evolution of a self-gravitating disk is obtained, taking into account the halo, in the form of matrix differential equations, and a method for its numerical analysis is developed to study the effect of the halo on disk formation. Numerical calculations were performed for various values of the system parameters, such as the initial perturbation, the circular speed of disk rotation, the ratio of the mass of the halo to the mass of the disk, and the time dependences of the major and minor semiaxes of the disk. The critical values of the system parameters are determined at which the halo stabilizes nonlinear and nonradial oscillations of the disk subsystem of galaxies at an early stage of their evolution.

AbstractEarly research on marine fungi was mostly descriptive, with an emphasis on their diversity and taxonomy, especially of those collected at rocky shores on seaweeds and driftwood. Subsequently, further substrata (e.g. salt marsh grasses, marine animals, seagrasses, sea foam, seawater, sediment) and habitats (coral reefs, deep-sea, hydrothermal vents, mangroves, sandy beaches, salt marshes) were explored for marine fungi. In parallel, research areas have broadened from micro-morphology to ultrastructure, ecophysiology, molecular phylogenetics, biogeography, biodeterioration, biodegradation, bioprospecting, genomics, proteomics, transcriptomics and metabolomics. Although marine fungi only constitute a small fraction of the global mycota, new species of marine fungi continue to be described from new hosts/substrata of unexplored locations/habitats, and novel bioactive metabolites have been discovered in the last two decades, warranting a greater collaborative research effort. Marine fungi of Africa, the Americas and Australasia are under-explored, while marine Chytridiomycota and allied taxa, fungi associated with marine animals, the functional roles of fungi in the sea, and the impacts of climate change on marine fungi are some of the topics needing more attention. In this article, currently active marine mycologists from different countries have written on the history and current state of marine fungal research in individual countries highlighting their strength in the subject, and this represents a first step towards a collaborative inter- and transdisciplinary research strategy.

Modeling 3D crustal velocities in the vicinities of Alaska and the Bering sea
Authors: Snay Richard A. , Freymueller Jeffrey T. , Dennis Michael L. 
Published: June 2023

AbstractThis document introduces Version 0.4 of the TRANS4D software, where TRANS4D is short forTransformations in Four Dimensions. TRANS4D enables geospatial professionals and others to transform three-dimensional positional coordinates across time and among several popular terrestrial reference frames. Version 0.4 introduces new crustal velocity models for the vicinities of Alaska and the Bering Sea, including parts of northwestern Canada and eastern Russia. These new models supplement existing velocity models for the continental United States as well as for most of Canada and for a neighborhood of the Caribbean plate. This document also provides evidence for the existence of a Bering tectonic plate, and it presents estimates for the Euler-pole parameters of this hypothesized plate. Moreover, estimated horizontal velocities computed at several geodetic stations located in Alaska provide evidence for the existence of part of the plate boundary separating the North American plate and the hypothesized Bering plate.
Prosodic words are the domain of emphasis spread: evidence from Northern Rural Jordanian Arabic
Authors: Jaradat Abdulazeez , Jarrah Marwan , Al-Deaibes Mutasim 
Published: June 2023

Abstract
This article, which reports on an experimental study based on data obtained from 86 native speakers of Northern Rural Jordanian Arabic (NRJA), offers empirical evidence that emphasis spread can apply bidirectionally across word edges when they are prosodically word internal. In other words, emphasis can spread from one word to a neighboring (plain) word when the two words form one prosodic word (ω). In order to support this hypothesis, we examine simple construct-state nominals (i.e., nominals consisting of two members), which are widely assumed to behave prosodically as one word in Arabic grammar (see, e.g., Borer, Hagit. 1999. Deconstructing the construct. In Kyle Johnson & Ian Roberts (eds.), Beyond principles and parameters, 3–89. Dordrecht: Kluwer). A simple construct state nominal is mapped onto one ω, as proposed in the current article. Additionally, this article examines instances of construct state nominals in which two words could be members of a ω by cliticization. In this case, a weak form (e.g., a reduced functional word such as an auxiliary verb) is attached to the ω of a lexical word, as an enclitic. The article shows that emphasis spreads across word edges within the ω mapped from a simple construct state nominal or a word along with its enclitics. In so doing, it provides evidence that the domain of emphasis spread is larger than the syllable, morpheme, or single-word form, as proposed by other studies for other Arabic varieties.
Modelling of the porous medium flow with pressure-dependent viscosity and drag coefficient
Authors: Marušić-Paloka Eduard , Pažanin Igor 
Published: June 2023

Abstract
In this paper we consider the porous medium flow through a corrugated channel where the viscosity of the fluid can significantly change with the pressure. Assuming the exponential dependence of the viscosity and drag coefficient on the pressure, we propose the higher-order approximation of the solution to the nonlinear boundary-value problem governing the flow. To accomplish that, we combine the concept of the transformed pressure with asymptotic techniques.
Sprague-Dawley Rats Differ in Responses to Medial Perforant Path Paired Pulse and Tetanic Activation as a Function of Sex and Age

Published: June 2023

AbstractNetwork plasticity in the medial perforant path (MPP) of adult (five to nine months) and aged (18–20 months) urethane-anesthetized male and female Sprague Dawley rats was characterized. Paired pulses probed recurrent networks before and after a moderate tetanic protocol. Adult females exhibited greater EPSP-spike coupling suggesting greater intrinsic excitability than adult males. Aged rats did not differ in EPSP-spike coupling but aged females had larger spikes at high currents than males. Paired pulses suggested lower GABA-B inhibition in females. Absolute population spike (PS) measures were larger post-tetani in female rats than male rats. Relative population spike increases were greatest in adult males relative to females and to aged males. EPSP slope potentiation was detected with normalization in some post-tetanic intervals for all groups except aged males. Tetani shortened spike latency across groups. Tetani-associated NMDA-mediated burst depolarizations were larger for the first two trains in each tetanus in adult males than other groups. EPSP slopes over 30 min post-tetani predicted spike size in female rats but not in males. Replicating newer evidence MPP plasticity in adult males was mediated by increased intrinsic excitability. Female MPP plasticity was related to synaptic drive increases, not excitability increases. Aged male rats were deficient in MPP plasticity.
Spns2/S1P: it takes two to tango with inflammation and metabolic rewiring during sepsis
Authors: Vanderhaeghen Tineke , Vandewalle Jolien , Libert Claude 
Published: June 2023

Sepsis is the result of a dysregulated host response to an infection and causes high morbidity and mortality at the intensive care units worldwide. Despite intensive research, the current management of sepsis is supportive rather than curative. Therefore, new therapeutic interventions for sepsis and septic shock patients are urgently needed. In this issue of EMBO Reports, Fang et al have used rat sepsis models to show that macrophage‐expressed SPNS2, a major transporter of S1P, is a crucial mediator of metabolic reprogramming of macrophages during sepsis which regulates inflammation via the lactate‐ROS axis.
Fiscal Sustainability and Risks of Provincial Government After Pandemic
Authors: Wibowo Tri 
Published: June 2023

The Covid-19 pandemic that has hit the world since the year 2019 puts fiscal pressure on the Governments of Indonesia. The Government of Indonesia has spent very big expenses to deal with the pandemic and recovery the national economic conditions. This condition will increase a fiscal risk level to achieve Gold Indonesia Vision of the year 2045. This article aims to assess the impacts of Covid-19 pandemic to fiscal sustainability of the central and provincial governments in Indonesia and identify the risks faced by the central and provicial governments after this outbreak. By using quantitative descriptive analysis and focus group discussion, it was identified an increase in the level of fiscal vulnerability in the central and provincial governments in Indonesia. The results of an analysis for the provincial government level conclude that provincial governments throughout Indonesia are under pressure on their fiscal sustainability. This is reflected in the decline in the Tax ratio, the increase in Debt to Income, and the increase in the budget deficit. This encourages the emergence of new risks that can interfere with efforts to achieve development goals. Several fiscal policies need to be taken to maintain fiscal sustainability like intensification and extensification of taxes and improving the quality of regional spending.

In the past few years, results from experimental and clinical studies have shown that inflammation can be both a consequence and a cause of epilepsy. Distinctive features of mesenchymal stem cells (MSCs) are their immunomodulatory and anti-inflammatory properties, which indicate promise in the field of epilepsy treatment.The article presents a review on the preclinical and clinical use of MSCs in the treatment of epilepsy, and outlines the mechanism of MSCs therapeutic action of in this disease. The authors focused on the analysis of all available in the literature clinical cases of MSCs use in the treatment of epilepsy, as well as the effectiveness and undesirable effects of therapy. The use of MSCs indeed has a significant effect in reducing the number of seizures and has a positive effect on mental functions, however, at present, this method of therapy is not ready for widespread clinical use due to the short period of observation in clinical trials and increased risks of developing immunological and oncological complications in patients.

Introduction: Surgical site infections (SSI) are one of the key problems in surgical practice. Despite the achievements of modern medicine, ongoing preventive measures, the incidence of wound infection remains quite high. This is especially relevant for oncoplastic surgery, since in most cases the installation of foreign materials (expanders, implants, meshes) is required to achieve a satisfactory cosmetic result.The purpose of the study: to identify the most common cause of infectious complications after reconstructive operations on the mammary gland using endoprostheses.Materials and methods: In a retrospective review of 526 consecutive implant-based breast reconstructions at a single institution from June 2020 to June 2022 was conducted. The frequency of development of infectious complications was assessed, as well as the taxonomic structure of the main pathogens that were isolated in the department of oncomammology in 2020–2022.Results: The incidence of infectious complications that led to the loss of the endoprosthesis during reconstructive surgery on the mammary gland was 6.7 %. The main causative agents of SSI leading to the loss of implants and the need for reoperations were Corynebacterium striatum (35.2 %) and Staphylococcus aureus (27.2 %). The spectrum of the most common pathogens that led to the loss of implants corresponded to the flora most often detected during bacterial culture in the department. The probability of implant loss was higher in the group of patients who underwent chemotherapy (14 of 197, 7.1 %) or chemoradiotherapy (14 of 188, 7.4 %) compared with patients who did not receive specific anticancer treatment (7 of 141, 4.9 %). However, taking patients who did not receive drug or radiation treatment as a reference group, statistical significance could not be achieved (p = 0.56 in the chemotherapy group and p = 0.49 in the chemoradiotherapy group).Conclusions: Our own experience has shown that, despite the current preventive measures, the frequency of infectious complications remains quite high. In the etiological structure of SSI pathogens, microorganisms of the genera Staphylococcus and Corynebacterium predominate. The use of broad-spectrum antibiotics in perioperative prophylaxis did not guarantee the absence of SSI in the postoperative period. An analysis of the sensitivity of isolated pathogens to antibacterial drugs, an assessment of the effectiveness of various antibiotic regimens in the future may allow us to develop an optimal antibiotic prophylaxis scheme for infectious complications during breast reconstructive surgery, therefore, further prospective studies in this direction are needed.
Identification of Potential Target Transcription Factor Genes Regulated by Krüppel Homolog 1 in Chilo suppressalis (Lepidoptera: Crambidae)

Abstract
Juvenile hormone (JH) is a major endocrine hormone that mediates development, metamorphosis, and reproduction in insects. It binds directly to its methoprene-tolerant receptor and recruits a heterodimer partner to form the JH–receptor complex that then activates a JH-inducible gene known as the Krüppel homolog 1 (Kr-h1). There is evidence that this gene is a downstream factor mediating both physiological and biochemical processes; however, the functional mechanism of Kr-h1 is largely unknown. Using the economically important rice (Oryza sativa L.) pest Chilo suppressalis (Walker) (Lepidoptera: Crambidae) as a model, we used a combination of RNA interference (RNAi), high-throughput RNA sequencing, and real-time quantitative polymerase chain reaction (RT-qPCR) to identify candidate transcription factor (TF) genes that are regulated by Kr-h1. RNAi knockdown of Krh1 identified the Zinc finger proteins, ZBTB, THAP, PAX, MYB, HSF, Homeobox, HMG, CSD, basic helix-loop-helix, STAT, RHD, and MBD families as regulated by Kr-h1. RT-qPCR confirmed the transcription levels of these putative TFs and indicated that knockdown of Kr-h1 can induce or suppress the expression of these proteins in C. suppressalis. These results provide the basic information required for in-depth research on the TFs regulated by Kr-h1 in C. suppressalis and other insects.
Attempt to Artificially Infect Cimex lectularius (Hemiptera: Cimicidae) with Bartonella henselae (Alphaproteobacteria: Bartonellaceae)

Published: June 2023

Abstract
Bed bugs (Hemiptera: Cimicidae) are common, hematophagous ectoparasites of humans and other animals and are experiencing an international resurgence. Cimicids have been suspected in the transmission of many disease agents, including Bartonella species; however, disease transmission of any kind has not yet been confirmed in natural disease cycles. Bartonella spp. are transmitted by a variety of arthropods, including fleas, lice, and sand flies, but the potential role of bed bugs in transmission remains unknown. In this study, we used an artificial membrane to feed rabbit blood, either infected or uninfected with Bartonella henselae Regnery et al. (Alphaproteobacteria: Bartonellaceae) to two groups of adult Cimex lectularius L. After 2 wks, the presence of B. henselae in the gut and salivary glands of bugs was assessed via PCR and transmission electron microscopy (TEM), respectively. Although 4 of 10 bed bug guts showed evidence of B. henselae, we were unable to visually detect B. henselae in any of the salivary gland TEM images.
A Review of Chemically Based Communication in Miridae, with a Focus on Two Sympatric Species of Eccritotarsus

Published: June 2023

Abstract
This report is a review of pertinent scientific literature on the chemical communication of the Miridae (Order Hemiptera; Suborder Heteroptera), with a focus on the sympatric species Eccritotarsus catarinensis Carvhalho and Eccritotarsus eichhorniae Henry. Both species have been deployed as biological control agents of water hyacinth, Pontederia (Eichhornia) crassipes (Martius) Solms-Laubach, in over 30 sites in South Africa. Our aim in this review was to gather and assimilate information on the chemical communication and chemical ecology of mirids, with an ultimate goal of enhancing the effectiveness of biological control agents of water hyacinth, particularly E. catarinensis and E. eichhorniae. Many hemipterans have highly developed metathoracic scent glands (MTGs), Brindley's glands, and secretory setae that store and emit chemicals that may act as allomones, kairomones, or pheromones. The preponderance of the available literature dealt with sex pheromones. Hexyl butyrate, (E)-4-oxo-2-hexenal, and (E)-2-hexenyl butyrate are reported to be sex pheromones in many mirids: for example, Adelphocoris fasciaticollis Reuter, Apolygus spinolae Meyer-Dür, Liocoris tripustulatus F., Lygocoris pabulinus L., several Lygus spp. (Lygus hesperus Knight, Lygus lineolaris Beauvois, Lygus elisus van Duzee, Lygus pratensis L., and Lygus rugulipennis Poppius), and Stenotus rubrovittatus Matsumura. Hexyl butyrate is the most prevalent sex pheromone in Miridae, while (E)-4-oxo-2-hexenal is the most prevalent sex pheromone in Heteroptera. Both pheromones co-occur in some species and exhibit many functionalities. The constancy of sex pheromones linked to behavioral patterns in Miridae suggest a punctuated equilibrium pattern of evolution (dating back to the Triassic), similar to morphological characters of many insects.
