Regulation of syncytiotrophoblast intracellular pH is critical to optimum enzymatic and transport functions of the placenta. Previous studies of Na+/H+ exchanger (NHE) activity in the placenta from pregnancies complicated by intrauterine growth restriction (IUGR) have produced conflicting results. The possible role of altered placental pH regulation in the development of acidosis in some fetuses s

BACKGROUND: Autonomic disorders of the cardiovascular system, such as orthostatic hypotension and elevated resting heart rate, predict mortality and cardiovascular events in the population. Low-energy-fractures constitute a substantial clinical problem that may represent an additional risk related to such autonomic dysfunction.AIMS: To test the association between orthostatic hypotension, resting

This review article considers the purposes and mechanisms of regulation of placental transfer in general terms and then illustrates some key points with reference to the Na+/H+ exchanger (NHE), a transport protein found in the syncytiotrophoblast. NHE probably has a role in the homeostasis of syncytiotrophoblast intracellular pH and may also be involved in syncytiotrophoblast cell volume regulatio

Despite its importance for placental function, syncytiotrophoblast Na+-K+-ATPase has not been studied in detail. We purified syncytiotrophoblast microvillous (MVM) and basal (BM) membranes from full-term human placenta. Western blotting with isoform-specific antibodies demonstrated the presence of the α1-subunit, but not the α2- or α3-subunits, in MVM and BM. Relative density per unit membrane pro

The effects on renal sodium excretion of giving lithium chloride (LiCl; 0.75 mmol per kg body mass) by gavage or intravenously were investigated. The experiments were carried out on Wistar-Kyoto (WKY) or spontaneously hypertensive (SHR) rats in metabolic cages. The rats had been on a low-salt diet for 4 days. Urine excretion of water, sodium and potassium was followed before and for 24 h after giv

Previous studies have shown that an oral sodium load during sodium deprivation is excreted faster than an intravenous load. We wanted to study whether the renin-angiotensin-aldosterone system might be associated with this phenomenon and therefore the influence of the angiotensin converting enzyme (ACE) inhibitor enalapril was investigated. The experiments were performed on four strains of rat: spo

An emerging concept in the ongoing battle against insect pests is that compounds thatinfluence the behavior of insects by modulating their ability to smell could be developedby targeting their chemoreceptors. This idea was identified by the annual horizon scan ofglobal conservation issues as a topic of concern for their 2015 report. Unfortunately, thepublication could only afford a short discussio

It is projected that forest disturbances, such as insect outbreaks, will have an increasingly negative impact on forests with a warmer climate. These disturbance events can have a substantial impact on forests' ability to absorb atmospheric CO2, and may even turn forests from carbon sinks into carbon sources; hence, it is important to develop methods both to monitor forest disturbances and to quan

Purpose– The purpose of this paper is to provide insights into, and guidance on, how to balance packaging standardisation and adaptation strategies in different markets in the fast moving consumer electronic goods (FMCEG) industry.Design/methodology/approach– The research was explorative in nature and was utilised in a case study format. The main data collection methods were a literature review, i

A comprehensive, three-dimensional model of a proton exchange membrane (PEM) fuel cell based on a steady state code has been developed. The model is validated and further be applied to investigate the effects of various porosity of the gas diffusion layer (GDL) below channel land areas, on thermal diffusivity, temperature distribution, oxygen diffusion coefficient, oxygen concentration, activation

Dysfunctional coagulation aggravates clinical outcome in patients with sepsis. The aim of this study was to define the role of Rac-1 in the formation of platelet-derived microparticles (PMPs) and thrombin generation (TG) in abdominal sepsis. Male C57BL/6 mice underwent cecal ligation and puncture (CLP). Scanning electron microscopy and flow cytometry were used to quantify PMPs. TG was determined b
