Maternal and Fetal Magnesium Balance: Impacts and Implications
No full textMagnesium (Mg2+) is an essential mineral that supports normal cellular metabolism, optimal musculoskeletal and neuronal functions, the immune response, and cardiovascular health. The regulation of magnesium is a complex process, and during pregnancy, it becomes even more challenging because of increased magnesium needs. Magnesium inadequacy during pregnancy can lead to severe complications, including preeclampsia in the mother, intrauterine growth restriction, preterm birth, low birth weight, insulin resistance, heart disease, and developmental delays in the neonate, due in part to its critical role in fetal musculoskeletal and nervous development. Magnesium deficiency during pregnancy is a global health concern, and raising awareness about the importance of maintaining magnesium balance, improving dietary intake, and promoting supplementation, when needed, could help reduce associated risks. This chapter discusses the impact of altered magnesium homeostasis on maternal health and fetal development while also addressing the need for global awareness and interventions to improve maternal and child health
How prestige and socio-economic status shape the linguistic landscape of Brownsville, Texas
No full textThis study explores the linguistic landscape of Brownsville, Texas, a bilingual community located on the east side of the U.S.-Mexico border. Public signage was analysed using quantitative methods to explore the relationship between socio-economic status and language choice, as well as the symbolic and instrumental functions of English and Spanish. The analysis also examines the relative prevalence of both languages to assess the ethnolinguistic vitality of Spanish, the representation of local Spanish varieties, and phenomena linked to language contact. Our findings reveal that the linguistic landscape reflects and reinforces social hierarchies, highlighting the dominant status of English and the emblematic use of Spanish to appeal to cultural authenticity. These results align with previous linguistic landscape studies carried out on other US-Mexico borders, contributing to the growing field of linguistic landscape research, and providing insights into the sociolinguistic dynamics of border towns
Interactive effects of hyposalinity and nitrate loading on growth, physiology, and nitrogen status of the seagrass, Halodule wrightii
No full textThe study goal was to examine the interactive physiological effects of two freshwater inflow stressors, nitrate pulses coupled with salinity decrease, on the seagrass Halodule wrightii. A microcosm experiment was designed to approximate an observed freshwater inflow event. Over a 13-day period plants were subjected to three sequential salinity drops (S35→ S23→ S15→ S5) with nitrate-nitrogen added simultaneously at 0, 30 or 60 µM. For comparisons, the Control was no salinity change and no nitrate added denoted by S35/No N. Measurements of H. wrightii shoot production, photosynthesis, respiration, quantum efficiency, %N, C:N ratios and δ15N values which were made after each salinity drop revealed differing effects of low versus high N levels under S35 compared to reduced salinity. Compared to the Control at the experimental endpoint, leaf net photosynthesis: respiration (P:R) ratio decreased 3-fold for hyposalinity + High N addition (S5/High N) largely due to increased respiration. Leaf %N increased and C:N ratio decreased concomitantly with both stressors, with S5/High N having the highest %N and lowest C:N ratio. While the magnitude of the effect was related to the amount of added N at S35, there were different effects of Low versus High N at low salinity (S5). The trends of P:R ratio, leaf %N and C:N ratio are consistent with increased respiration, uptake of added N, and depletion of carbon reserves. However, δ15N suggested that added NO3- was taken up by leaves at S35, but not at S5. The increased %N at S5 may be due to translocation of amino acid N from rhizomes-roots to leaves. Metabolic networks were hypothesized to be regulated differently at 30 versus 60 µM NO3- under conditions of hyposalinity. These findings add to the growing evidence that simultaneous stressors typical of substantial freshwater inflow events, hyposalinity and nitrate loading, could adversely affect H. wrightii
Food for Thought: A Review of Food in Organizational Contexts
No full textFor years, organizational scholars have studied the role of human physiology in applied settings. Under this broad umbrella, researchers have recently given specific attention to the interplay between employee food consumption and organizational phenomena. This focus on food is natural, considering that acquiring food is a foundational human motivation and that food is often consumed within the workplace. However, despite recent inroads, research on this topic remains limited, especially studies involving interpersonal and episodic dynamics. As such, we present a framework of employee food consumption and outline individual-, interpersonal-, and organizational-level predictors and outcomes. Additionally, we discuss how the nexus between work and food can be better understood by considering biological, psychological, and social mechanisms. Based upon our review of the literature, we identify new lines of inquiry that can help drive the field forward. We also describe the theoretical and practical implications of our framework
Accelerated Fully-Coherent Search for Compact Binary Coalescences
No full textProgress in Gravitational Wave data analysis is often limited by global optimization challenges rooted in the fitting of complex signal models. The fully coherent all-sky (FCAS) search for compact binary coalescences (CBCs), which requires optimizing the likelihood function of data from a detector network over CBC signal parameters, is particularly demanding. Despite its greater sensitivity, a real-time FCAS search has been impossible so far with traditional optimization methods using deterministic or Markovian parameter space sampling. We introduce a solution combining Particle Swarm Optimization (PSO) with GPU acceleration that achieves a ≈48-fold speed-up over real-time analysis, and a potential latency of ≲5 sec, for the demanding scenario of a 4-detector network and low-mass signals. With large-scale simulations of Frequentist parameter estimation errors in an FCAS search now possible, we explore the regularization of the inverse problem in network analysis
The Diabetes Education Arena: Results of the 2025 ADCES National Practice Survey of Diabetes Care and Education Specialists
No full textPurpose: This article reports the results of the 2025 National Practice Survey (NPS), documenting professional engagement in the diabetes care and education specialist (DCES) specialty, conducted by the Association of Diabetes Care & Education Specialists (ADCES).
Methods: The quantitative NPS survey was administered online using email addresses compiled from ADCES and Certification Board for Diabetes Care and Education. Data were collected over a 4-week period in 2025. Descriptive and correlative statistics were used to identify relationships between variables and are discussed in the context of existing literature and previous NPS surveys.
Results: The responses from the 2479 respondents to this NPS find those serving as DCESs to be a diverse group of professionals, working within the context of both an expanding diabetes care team and population with diabetes. While serving disparate populations, they appear, as a group, to actively seek out training opportunities to further their understanding of those they work with and professional credentialing and other educational advancement. DCESs appear to have an expanded role in patient care and increased responsibility in providing colleagues and people with diabetes with guidance on diabetes-related technology.
Conclusions: Given the advances in the care and treatment of diabetes, DCESs are an important conduit for patient-centered care. Understanding the current practice of the DCES provides insights to address the evolving needs of diabetes prevention, diabetes and cardiometabolic syndrome care, treatment, and education with a workforce prepared to integrate technology and best practices for people living with diabetes
Oil price shocks and interest rates in major economies
No full textWe investigate in this paper the effects of oil price shocks on exchange rate pass-through (ERPT), inflation, and interest rates. We use a global vector autoregressive (GVAR) model with 30 economies (11 major economies plus 19 economies within the Eurozone), monthly data from 1999M4 to 2022M2, and time-varying bilateral trade. We examine generalized impulse response functions (GIRF) of West Texas Intermediate (WTI) shocks under two identification schemes: feedback effects with oil and exogenous oil. In the commodity currencies of Canada, Norway and South Africa, interest rates move positively in response to oil price shocks. In the U.S., the response is considerably higher. Russia is the exception with interest rates falling after oil price shocks. Our results remain robust across various alternative specifications, including structural vector autoregressive (SVAR) with reasonable causal ordering. Our model captures the direct effects of oil price shocks on inflation and indirect effects through pass-through mechanisms
