Introdução: A síndrome HELLP é uma condição da gravidez e puerpério que ocorre em pacientes com pré-eclâmpsia, na qual o hematoma subcapsular hepático representa rara, mas grave complicação a ela associada. Sua etiopatogenia é desconhecida. No entanto, a lesão do endotélio vascular e as alterações no sistema de coagulação, presentes na doença, contribuem para o aparecimento do hematoma. Objetivo: Analisar a prevalência e a evolução clínica do hematoma subcapsular hepático em pacientes com síndrome HELLP em uma maternidade pública de referência de Teresina-PI. Metodologia: Trata-se de coorte retrospectivo no qual foram analisadas prevalência e evolução clínica do hematoma subcapsular hepático em pacientes com pré-eclâmpsia e síndrome HELLP internadas em maternidade pública de Teresina-PI, no período entre 01 de janeiro de 2019 e 31 de dezembro de 2022. Resultados: Foram selecionados prontuários de 301 pacientes, das quais 239 (79,40%) apresentaram pré-eclâmpsia, 58 pacientes (19,26%) tiveram simultaneamente pré-eclâmpsia e síndrome HELLP e 4 pacientes (1,34%) apresentaram pré-eclâmpsia, síndrome HELLP e hematoma subcapsular hepático. Considerando-se apenas as pacientes com síndrome HELLP, a prevalência é de 6,89%. Destas, 03 (75%) evoluíram com ruptura hepática e foram submetidas à laparotomia exploradora. Não ocorreu nenhum óbito. Nas pacientes submetidas ao tratamento cirúrgico, o tempo médio de internação foi de 31,66 dias; já na paciente com tratamento conservador, o tempo de internação foi de 15 dias. Conclusões: A prevalência de hematoma hepático em pacientes com síndrome HELLP foi de 6,89%. Em 03 pacientes (75%) ocorreu ruptura, tendo duas evoluído com instabilidade hemodinâmica, anemia grave e choque hipovolêmico. A abordagem cirúrgica com tamponamento hepático foi adotada nos três casos. Não ocorreram óbitos maternos.

A talassemia β é uma condição hematológica hereditária caracterizada pela diminuição ou ausência da síntese de cadeias β-globina. Esta condição apresenta desafios significativos durante a gestação devido ao risco de anemia hemolítica, tanto para a mãe quanto para o feto. O teste do pezinho emerge como uma ferramenta essencial para a detecção precoce de talassemias e outras doenças genéticas, permitindo intervenções terapêuticas adequadas. Esta revisão de literatura tem como objetivo examinar a relevância do teste do pezinho na detecção precoce da talassemia e seu impacto na saúde materna e neonatal. Foram considerados artigos originais, revisões sistemáticas, metanálises e diretrizes clínicas publicadas nos últimos 10 anos. A análise dos estudos selecionados demonstra que o teste do pezinho desempenha um papel crucial na detecção precoce da talassemia, permitindo o início imediato de medidas terapêuticas, como a suplementação de ferro e transfusões sanguíneas, quando necessário. Além disso, a identificação precoce de casos de talassemia durante o pré-natal possibilita a oferta de aconselhamento genético aos casais em risco, contribuindo para a prevenção de futuras gestações afetadas. Essas intervenções têm o potencial de reduzir significativamente a morbidade e mortalidade associadas à talassemia tanto para a mãe quanto para o neonato. A revisão da literatura destaca a importância fundamental do teste do pezinho na detecção precoce da talassemia e seu impacto positivo na saúde materna e neonatal. A integração eficaz deste teste nos programas de cuidados pré-natais pode desempenhar um papel significativo na melhoria dos resultados de saúde para mulheres grávidas e seus bebês.
Impact of new type of plastic as aggregate on fresh and hardened, microstructure properties of concrete
Authors: Muayad Saleh Abeer , Mahmoud Hama Sheelan
Published: June 2024

The goal of this work is to reuse plastic waste as a result of the production of valves on gas bottles into concrete. In this way, one can reduce and consume that waste and at the same time reuse it in concrete and study its effects on its properties to decide which best content. This kind of plastic waste was used in different quantities (5 %, 7,5 %, 10 %, 12,5 %, and 15 %) to replace fine natural aggregate (sand) partially. The effects of these ratios on the fresh concrete's slump factor, the density of hardened concrete, compressive strength, absorption, microstructure, and ultrasonic pulse speed were studied and compared with a reference mixture free of plastic waste. The ANOVA analysis was used to analyze the results of the fresh and hardened tests, and it was concluded that 5 % was the ideal percentage of the percentages used, as it had less negative influence on the properties of concrete. From laboratory work, it was concluded that increasing the percentage of plastic waste has a negative impact on the properties of concrete, such as reducing compressive strength, flexural strength, spitting tensile strength, and increasing absorption
Reduction of the Wetting Collapse of Sandy Gypseous Soil by Using Microbial-Induced Calcite Precipitation
Authors: Sulaiman Hadeel S. , Al-Sharrad Muayad A. , Abed Idham A.
Published: June 2024

Microbial-induced carbonate precipitation (MICP) is a promising technology for cementing sandy soils, improving ground, repairing concrete cracks, and remediating contaminated land. The aim of this research is to implement this technology in mitigating wetting collapse of Ramadi sandy gypseous soil which has a gypsum content of about 35 %. To achieve this aim, the urease-producing bacterial strain Bacillus Megaterium SI was used and treated soil specimens were prepared. The preliminary results showed a well-defined bacterium activity with a precipitated calcite of 13-16,5 % by the end of the first week. The results of the collapsibility test showed that increasing cementation solution molarity from 0,25M to 1M lowered the wetting strain and total strain caused by both loading to 100 kPa and wetting by about 75 %. Therefore, the MICP demonstrates the potential to mitigate the wetting collapse of the sandy gypseous soil despite its high gypsum content.

The Commodification of Feminism — A Critical Analysis of Neoliberal Feminist Discourse
Authors: Bennett Sarah Louise
Published: June 2024

This paper critically examines the commodification of feminism within the framework of neoliberal feminism, a discourse that has gained significant traction in recent years. Neoliberal feminism emphasizes individual empowerment, personal success, and market-driven solutions to gender inequality. While this approach has succeeded in making feminist ideas more mainstream and accessible, it also poses substantial challenges by overlooking systemic and structural barriers that many women face. This paper explores the historical emergence of neoliberal feminism, its key characteristics, and the role of media and corporations in promoting commodified feminist ideals. It further analyzes the positive and negative impacts of neoliberal feminism on broader feminist movements, highlighting the shift from collective action to individual empowerment. Through critical perspectives from radical, intersectional, and socialist feminists, this paper underscores the limitations of neoliberal feminism and calls for a renewed focus on collective action, intersectionality, and systemic change to achieve true gender equality. By resisting the commodification of feminist ideals and advocating for more inclusive strategies, the feminist movement can better address the root causes of gender inequality in a neoliberal context.

On the Surprising Retention Order of Ketamine Analogs Using a Biphenyl Stationary Phase
Authors: Noreng Line , Wilson Steven , Øiestad Elisabeth , Øiestad Åse
Published: June 2024

An unexpected retention order for the ketamine analogs methoxpropamine (MXPr) and methoxisopropamine (MXiPr) was observed when using a biphenyl stationary phase for liquid chromatography-mass spectrometry (LC–MS). For separations of isomeric pairs of drugs (ketamine analogs, tryptamines, fentanyls, and nitazenes), branched-chain compounds are eluted before straight-chain compounds when using acetonitrile or methanol in mobile phases with C18 or biphenyl stationary phases. However, when a biphenyl stationary phase was paired with methanol, the opposite retention order for MXPr and MXiPr occurred, which was not observed when using acetonitrile in the mobile phase. The phenomenon persisted in biphenyl columns from two vendors. This study suggests additional work may be needed to understand the retention mechanisms when using biphenyl stationary phases. It is an example that we can still expect the unexpected when investigating alternative stationary phases of reversed-phase liquid chromatography (RPLC).

Scientific meetings and conferences are a cornerstone of scientific culture. By bringing people together around a shared purpose, meetings serve as a platform for knowledge exchange and can often foster a sense of belonging. As some will argue, conferences can become “counterspaces” to affirm a person’s identity, provided they have adequate access to resources and support (Nakajima et al., 2024). From students to retirees, scientific meetings and conferences provide engagement and professional development opportunities for people from various career tracks and stages and serve as engines of innovation and collaboration. As a major source of revenue, meetings and conferences are also integral to the business models of many professional societies, publishers, exhibitors, businesses, and local economies.
The “Net” Impact of Hydrothermal Venting on Oceanic Elemental Inventories: Contributions to Plume Geochemistry from the International GEOTRACES Program
Authors:   Texas A&M University, Fitzsimmons Jessica , Steffen Janelle
Published: June 2024

Hydrothermal vents serve as a primary interface between the cold deep ocean and the warm oceanic crust. While early research showed that seawater-​rock interactions add to or remove elements from seawater during the generation of hydrothermal fluids, consideration of these fluid fluxes alone does not relay the total impact that hydrothermal systems have on seawater geochemistry. In addition, hydrothermal plumes, areas where hydrothermal fluids mix with ocean waters, are host to a range of particle precipitation and scavenging reactions that further modify gross hydrothermal fluid fluxes to define the total “net” hydrothermal impact on oceanic inventories. Here, we review the major discoveries made by the international GEOTRACES program regarding the geochemical transformations occurring within hydrothermal plumes. We classify each element into one of five categories based on its behavior in hydrothermal plumes, a spectrum spanning the geochemical mass balance between net hydrothermal source fluxes and net hydrothermal plume scavenging sinks. Overall, we celebrate the role that GEOTRACES has played in defining the extent and dynamics of hydrothermal plume geochemistry, which is a crucial lever for determining global hydrothermal impacts.

Published: June 2024

As cross-border online purchase numbers surge, the factors that motivate or hinder consumers' desire for such shopping remain unclear. In order to better understand the "cross-border online shopper", this empirical study draws a comparison between customers from an advanced country (Germany) and customers from an emerging market (Romania). This research presents important insights for online retailers regarding the trade-off consumers encounter in cross-border e-commerce and the impact of perceived benefits and risks on their purchasing intentions. Our study examines two distinct country markets with diverse cultural and economic backgrounds to demonstrate how sociological and cultural attitudes influence online cross-border commerce similarly or differently.
Clinical Aspects in Which Symptoms May Indicate Cerebrospinal Fluid (CSF) Analysis
Authors: Neagoe Mariana-Alis
Published: June 2024

This chapter aims to describe clinical aspects in which examination of cerebrospinal fluid is essential for diagnosis. Clinical signs and symptoms that may indicate analysis of cerebrospinal fluid may include changes in mental status, severe headache, difficulty speaking, difficulty walking, dizziness, fever, muscle weakness, sensitivity to light, and seizures. Cerebrospinal fluid is frequently collected by lumbar puncture—a procedure of mainly diagnostic value. Examination of the cerebrospinal fluid determines the appearance, chemical and cytological composition, and pressure. In some conditions, analysis of cerebrospinal fluid is no longer necessary to establish the diagnosis, but the presence of changes in cerebrospinal fluid increases the level of “comfort” for diagnosis. Today, the lumbar puncture is no longer used to examine all types of central nervous system disorders. However, it is still used to diagnose central nervous system infections, neuro-immunological disorders, tumours, Guillain-Barré syndrome, and multiple sclerosis.

Published: June 2024

The functions of the immune system in the human body are related to immune response to the entry of foreign components into the body. In protecting the body from disease, the immune system has four main functions: recognition, effect, adjustment, and memory function. Lymphocytes are specific immune systems against pathogen antigens, to ensure that when the next attack of the same pathogen comes, it can be dealt with quickly and vigorously as well as become more immune. These lymphocytes, when formed for the first time, have specific properties, which, in the absence of use, remain in the body as naive. Basically, lymphocytes are divided into two based on their roles, namely, B and T lymphocytes. Activation of T cells will form several types of effector cells, such as cytotoxic, T-helper (Th), and regulator (Treg) cells. Cytotoxics kill pathogens and body cells infected by the virus. Th cells provide additional signals aimed at activating B cells to produce antibodies, also capable of activating other cells such as macrophages to eliminate pathogen in the body. Treg cells function to suppress the activity of the immune system of other lymphocytes so that the immunological reaction does not occur excessively.

Authors: Akindeji Jerome Sabejeje , Nurudeen Adewumi Adebare , Cheng Yi Yi , Su Huaneng , Khotseng Lindiwe
Published: June 2024

Palladium (Pd) nanoparticles supported by graphene nanomaterials were prepared and tested in this work using methanol as the fuel. The synthesized nanoparticles were used as electrocatalysts for direct methanol fuel cell. The support materials were synthesized by modified Hummer’s method and subsequently doped with nitrogen using melamine. The electrocatalysts were synthesized using modified polyol method. The synthesis method of the electrocatalyst was further modified by adjusting the pH of the electrocatalyst from 12 to 13. The structural characterization of the support materials was carried out using Fourier Transform Infrared (FT-IR) spectroscopy and Brunauer-Emmett-Teller (BET) technique while that of the electrocatalysts was also done using X-ray diffraction (XRD) and high-resolution transmission electron microscopy (HR-TEM). The elemental analysis was carried out using energy dispersive spectroscopy (EDS) to validated the presence of N-doped in Nitrogen-doped graphene oxide (NGO) and NrGO support materials and the Pd loading. The electroactivity, electron kinetics and stability of the electrocatalyst towards methanol oxidation were evaluated using cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and chronoamperometry (CA) respectively. The results showed that the modification of electrocatalyst by increasing the pH to 13 did not improve the activity of the electrocatalyst generally since the supported Pd catalysts synthesized by modified polyol method exhibited better electroactivity towards methanol oxidation than their pH 13 counterparts.
Dynamic Adaptations in the Human Low-Pressure Compartment Facilitating Cardiovascular Responses at Rest and Exercise
Authors: J.B. Robinson Vincent , Chow Lauren , Mehta Vinay , Oribabor Charles
Published: June 2024

The experimental description of the low-pressure cardiovascular compartment was developed from studies involving anesthetized whole animals. There are few studies in alert, conscious humans delineating the acute adaptations of the low-pressure compartment to maintain cardiovascular function and homeostasis in the variable demands of changing body positions and from rest to exercise. Available empirical data shows that the low-pressure compartment is effective at sequestering blood volume in response to medications and volume loading. Additionally, this unstressed blood volume can be mobilized acutely in situations of increased cardiac output such as exercise or mental stress. This mobilization during exercise is also associated with acute improvement of the low-pressure compartment conduit function (pulmonary and IVC conduit vessels). The unstressed volume mobilized from peripheral beds is also used to load the pulmonary vascular reservoir in addition to dilating low-pressure compartment conduit vessels. The low-pressure compartment is gravity and extramural pressure sensitive which leads to differences in cardiac filling capabilities in different body positions and body habitus. In this chapter we will review available data primarily in alert, conscious humans which provides insights to low-pressure compartment functioning at rest and at mental and physical stress.
Coma and Brain Death: Facts, Myths, and Mysteries
Authors: Prakash Pooja
Published: June 2024

Death is one of universal fact that no one can change, but ongoing advanced medical techniques have created equal challenges to nature. The process of death counts complicated grieving, medical treatment, estate planning, organ donation, and legal and ethical issues. When all vital organs and body systems cease to function, there is end of life. The Uniform Determination of Death Act has stated that “an individual who has sustained either irreversible cessation of circulatory and respiratory functions or irreversible cessation of all functions of the entire brain, including the brainstem, is dead.” The legal and clinical concept of brain stem death has differentiated coma as a state of prolonged, profound unconsciousness where a person is unresponsive to painful stimuli, light, or sound and cannot be woken. The chapter aimed to detect the fact, myth, and mystery behind coma and brain death, using a legal, clinical, and traditional view.

A special resolution had the president of the Confederation of Latin American Workers (CTAL), Vicente Lombardo Toledano, travelling all around the continent in the months following the confederation’s First General Congress. The trip was planned to be between August and December of 1942 and included 12 countries; it was an opportunity to consolidate the continental unionism organized around CTAL. During the trip there were acknowledgements, workers’ renewed expectations that they would indeed achieve labour rights, as well as conflicts due to CTAL’s political, union and strategic influence. The popular workers’ unity, the opposition to “nazi-fascism” and the desire for a better future for the continent were all part of the scope of the trip.

Este artículo problematiza desde una perspectiva historiográfica el desarrollo de la mortalidad en la infancia en la Provincia de Concepción entre 1900 y 1930. El objetivo es conocer las singularidades del fenómeno demográfico mortal y las estrategias que la elite médico-política local creó para solucionarlo. La hipótesis testada sugiere que la incipiente pediatría en conjunto con la modernización de las obras sanitarias aumentó la calidad de la vida de los niños penquistas haciendo disminuir paulatinamente el número de muertos. Las fuentes históricas en las que se basó la hermenéutica fueron diversas: periódicos, revistas científicas, documentación municipal y expedientes criminales. Los datos proporcionados por las fuentes permitieron analizar la vivienda popular, la demografía médica, la alimentación y cuidados de los niños, y la situación de los centros de asistencia sanitaria. Las conclusiones subrayan que la elite médico-política provincial transformó las condiciones estructurales y de los agentes permitiendo mejorar los indicadores de la mortalidad infantil en un proceso lento que sólo se hizo notorio hacia mediados de los años veinte.

O Caryocar brasiliense, conhecido como pequi, árvore de grande porte e longevidade, desempenha um papel ecológico significativo no bioma Cerrado, sendo uma espécie pioneira na regeneração vegetal após distúrbios naturais ou antrópicos. A versatilidade do pequi, devido ao uso de suas estruturas orgânicas e distribuição geográfica ampla, o tornam um recurso de alto valor econômico e grande potencial alimentício, industrial, cosméticos, medicinais, farmacológicos e outros. Analisando a história dos primeiros viajantes naturalistas do século XIX até o centenário do descobrimento do Brasil, o estudo propõe, fundamentado na História Ambiental, mapear a trajetória e os usos do pequi no Planalto Central Brasileiro. Enfatiza-se a relevância das viagens naturalistas, sobretudo europeias do século XIX, na construção da identidade brasileira e no estudo da natureza, destacando a importância dos relatos desses viajantes como fonte historiográfica. A investigação ressalta ainda a relação histórica entre homens e plantas, evidenciando como o estudo detalhado da história natural pode impactar a compreensão da interdependência entre seres humanos e natureza no século XXI e a importância do conhecimento da história da natureza para a formação de identidade individual e coletiva.

active development and structural changes in the fitness services market, rapid changes in consumer preferences of fitness club clients create the prerequisites for finding new ways to formulate a marketing strategy for promoting professional fitness equipment. Based on the concept of cognitive marketing and stakeholder theory, the article proposes the concept of a multi-sided platform (ecosystem) in the fitness services market, uniting all key stakeholders. A coordinated development strategy for participants in the fitness ecosystem allows you to implement and adapt a marketing strategy of a qualitatively different level, taking advantage of all the benefits that participation in a multilateral platform provides. The highest level of quality in targeting target segments is achieved, allowing for the establishment of sustainable channels for the promotion of professional fitness equipment. The proposed concept can be used to develop a methodology for cascading a marketing strategy to the operational level in the business activities of manufacturers of professional fitness equipment working on a multilateral platform model.
Theoretical approaches to the interpretation of market locality
Authors: Лавщенко С.П.
Published: June 2024

статья посвящена анализу теоретических подходов к понятию признака локальности в исследовании рынков. В работе на основе оценки текстов научных статей, а также практики применения термина локальный, сделан вывод об отсутствии единых подходов к его трактовке. Отмечено, что правовое регулирование также имеет различные интерпретации признака локальности, однако наиболее часто он применяется по отношению к рынку в границах муниципального образования. Установлено, что подходы к определению границ локализации рынка имеют отличающиеся методологические основания и обуславливает целесообразность ведения анализ рынка посредством включения в него расширенного спектра признаков локальности для более глубокого изучения данного феномена.

the article is devoted to the analysis of theoretical approaches to the concept of the sign of locality in the study of markets. Based on the evaluation of scientific articles and the practice of applying the term local, the paper concludes that there are no unified approaches to its interpretation. It is noted that legal regulation also has different interpretations of the sign of locality, but it is most often applied to the market within the boundaries of a municipality. It is established that approaches to determining the boundaries of market localization have different methodological bases and makes it expedient to conduct the analysis of the market by including an extended range of signs of locality for a deeper study of this phenomenon.
