The magnesium global network (MaGNet) to promote research on magnesium in diseases focusing on covid-19
2021
When the current SARS-CoV-2 pandemic began in early 2020, the global magnesium researcher community came together and noted the striking similarities between COVID-19 risk factors and conditions associated with magnesium deficit state in humans, reasoning that magnesium deficiency could worsen the course of COVID-19 [1-4]. This prompted establishment of a worldwide collaborative network with regular virtual meetings to brainstorm the associations between magnesium and COVID-19. We hypothesize that magnesium deficiency, a common but mostly unrecognized state in modern global societies, could be an important component of the susceptibility to SARS-CoV-2 infection. Consequently, restoring the …
Contents of free amino acids in needles of Norway Spruce trees in relation to novel forest decline. Studies on trees from a site in the northern Blac…
1993
The free amino acid content in needles of Norway spruce trees (about 45-year-old) was determined by means of HPLC. The studied trees have been growing at a forestry site in the Black Forest which is characterized by a high impact of ozone and magnesium deficiency. Measurements were carried out on visibly healthy and on damaged trees on several dates during two vegetation periods and during the course of a day. The amino acids occurring at the highest concentrations were glutamate, arginine, aspartate, and glutamine. The typical seasonal changes in the content of free amino acids, with their minimum during summer, were disturbed in the needles of the damaged trees. Particularly in summer and…
Magnesium metabolism in hypertension and type 2 diabetes mellitus.
2007
The increasing evidence for the clinical relevance of altered magnesium metabolism to states of altered insulin resistance confirms the role of magnesium deficit as a possible underlying common mechanism of the "insulin resistance" of hypertension and altered glucose tolerance. The pioneer work of Lawrence M. Resnick and his group using the cellular ion-based approach that we are only partially presenting here has consistently contributed to the progress of the field, demonstrating (a) the critical importance of magnesium metabolism in regulating insulin sensitivity as well as vascular tone, and blood-pressure homeostasis; (b) that magnesium deficiency, defined on the basis of intracellular…
Effect of oral magnesium supplementation on physical performance in healthy elderly women involved in a weekly exercise program: A randomized control…
2014
Background: Magnesium deficiency is associated with poor physical performance, but no trials are available on how magnesium supplementation affects elderly people’s physical performance. Objective: The aim of our study was to investigate whether 12 wk of oral magnesium supplementation can improve physical performance in healthy elderly women. Design: In a parallel-group, randomized controlled trial, 139 healthy women (mean 6 SD age: 71.5 6 5.2 y) attending a mild fitness program were randomly allocated to a treatment group (300 mg Mg/d; n = 62) or a control group (no placebo or intervention; n = 77) by using a computer-generated randomization sequence, and researchers were blinded to their …
Magnesium and hypertension in old age
2021
Hypertension is a complex condition in which various actors and mechanisms combine, resulting in cardiovascular and cerebrovascular complications that today represent the most frequent causes of mortality, morbidity, disability, and health expenses worldwide. In the last decades, there has been an exceptional amount of experimental, epidemiological, and clinical studies confirming a close relationship between magnesium deficit and high blood pressure. Multiple mechanisms may help to explain the bulk of evidence supporting a protective effect of magnesium against hypertension and its complications. Hypertension increases sharply with advancing age, hence older persons are those most affected…
Early developmental alterations of low-Mg2+ -induced epileptiform activity in the intact corticohippocampal formation of the newborn mouse in vitro.
2005
Abstract The generation, propagation and pharmacological properties of low-Mg 2+ -induced epileptiform activity were examined in the intact corticohippocampal formation (CHF) of the newborn (P0–4) mouse in vitro. Multi-site field potential recordings in dentate gyrus (DG), CA3, CA1, entorhinal cortex (EC) and temporal cortex (TC) revealed in 0.2 mM Mg 2+ -containing ACSF a stable pattern of spontaneous epileptiform activity consisting of recurrent ictal-like events (ILEs) and interictal events (IEs). Although this activity could be consistently observed as early as P0, ILEs were smaller in amplitude, less frequent and showed a slower onset in P0–2 as compared to P3–4 animals. In all age gro…
