In this study, fertilized mirror carp eggs were allowed to develop in fresh water with various magnesium concentrations (0.05, 0.2 and 2 mg l). The percentage of dead (eggs+prelarvae) and deformed prelarvae increased sharply to 94% at an ambient magnesium concentration of 0.05 mg l compared with 22 and 10% at ambient magnesium concentrations of 0.2 mg l and 2.0 mg l, respectively. Mirror carp r...

The opportunistic bacterial pathogen Pseudomonas aeruginosa colonizes airways of individuals with cystic fibrosis (CF) with resultant chronic destructive lung disease. P. aeruginosa adaptation to the CF airway includes biofilm formation and antibiotic resistance. Isolates from asymptomatic individuals in the first 3 years of life have unique characteristics, suggesting that adaptation occurs be...

Acute severe asthma is one of the most common medical emergency situations in childhood, and physicians caring for acutely ill children are regularly faced with this condition. In this article we present a summary of the pathophysiology as well as guidelines for the treatment of acute severe asthma in children. The cornerstones of the management of acute asthma in children are rapid administrat...

Despite its success as a potent antineoplastic agent, ∼25% of patients receiving cisplatin experience acute kidney injury (AKI) and must discontinue therapy. Impaired magnesium homeostasis has been linked to cisplatin-mediated AKI, and because magnesium deficiency is widespread, we examined the effect of magnesium deficiency and replacement on cisplatin-induced AKI in physiologically relevant o...

Infusion of magnesium salts into the body cavity of freshwater-adapted rainbow trout led to elevated plasma magnesium concentrations and to stimulation of renal tubular secretion of magnesium. The majority of the infused load was excreted renally, no net branchial excretion being detected. Magnesium sulphate infusion led to increased tubular secretion of sulphate. Magnesium chloride infusion le...

Magnesium deficiency is frequently associated with hypokalemia. Concomitant magnesium deficiency aggravates hypokalemia and renders it refractory to treatment by potassium. Herein is reviewed literature suggesting that magnesium deficiency exacerbates potassium wasting by increasing distal potassium secretion. A decrease in intracellular magnesium, caused by magnesium deficiency, releases the m...

Carp eggs, fertilized in vitro, were allowed to develop in fresh water with magnesium concentrations varying from 0.001 to 0.100 mmol l-1. Magnesium concentrations below 0.010 mmol l-1 seriously impeded carp embryonic development: the incidence of deformed larvae and mortality increased steeply to 100% at water magnesium concentrations of 0.001 mmol l-1. Thus, early life stages of carp require ...

The interactions between genes and the environment are now regarded as the most probable explanation for autism. In this review, we summarize the results of a metallomics study in which scalp hair concentrations of 26 trace elements were examined for 1,967 autistic children (1,553 males and 414 females aged 0-15 years-old), and discuss recent advances in our understanding of epigenetic roles of...

BACKGROUND The primary aim of this study is to assess, using individual participant data (IPD) meta-analysis, the effects of administration of antenatal magnesium sulphate given to women at risk of preterm birth on important clinical outcomes for their child such as death and neurosensory disability. The secondary aim is to determine whether treatment effects differ depending on important pre-s...

Febrile seizures (FS) are the most common cause of seizures in children. The exact etiopathogenesis is unknown but involves factors like genetic predisposition and alterations in the levels of neurotransmitters and some trace elements. The study includes 48 consecutive children with FS, and 55 healthy age matched control subjects. Calcium, magnesium and potassium concentrations in the febrile s...
