the effects of the calcium Magnesium Bicarbonate content in thermal mineral water on chronic low back pain a randomized controlled follow up study
International Journal of Biometeorology, 2018Co-Authors: T Gati, I K Tefner, L Kovacs, K Hodosi, T BenderAbstract:The aim of this study was to investigate the effects of balneotherapy on chronic low back pain. This is a minimized, follow-up study evaluated according to the analysis of intention to treat. The subjects included in the study were 105 patients suffering from chronic low back pain. The control group (n = 53) received the traditional musculoskeletal pain killer treatment, while the target group (n = 52) attended thermal mineral water treatment for 3 weeks for 15 occasions on top of the usual musculoskeletal pain killer treatment. The following parameters were measured before, right after, and 9 weeks after the 3-week therapy: the level of low back pain in rest and the level during activity are tested using the Visual Analog Scale (VAS); specific questionnaire on the back pain (Oswestry); and a questionnaire on quality of life (EuroQual-5D). All of the investigated parameters improved significantly (p < 0.001) in the target group by the end of the treatment compared to the base period, and this improvement was persistent during the follow-up period. There were no significant changes in the measured parameters in the control group. Based on our results, balneotherapy might have favorable impact on the clinical parameters and quality of life of patients suffering from chronic low back pain.

structure and dynamics of the hydrated Magnesium ion and of the solvated Magnesium carbonates insights from first principles simulations
Physical Chemistry Chemical Physics, 2010Co-Authors: Devis Di Tommaso, Nora H De LeeuwAbstract:We report first principles molecular dynamics simulations based on the density functional theory and the Car–Parrinello method to study the structures and dynamics of the hydrated Mg2+ ion and of the solvated MgHCO3+ and MgCO3 complexes in aqueous solution. According to these simulations, the first hydration shell of the hydrated Magnesium ion consists of six water molecules, whereas in the solvated Magnesium Bicarbonate and Magnesium carbonate complexes the Mg2+ is mostly five-coordinated, which indicates that when coordinated to Magnesium the HCO3− and CO32− anions reduce its the coordination sphere. Our simulations show that the structures of the most stable monomers of Magnesium bi-carbonate and Magnesium carbonate in solution are Mg[η1-HCO3](H2O)4+ and Mg[η1-CO3](H2O)4, i.e. the preferred hydration number is four, while the (bi-)carbonate is coordinated to the Magnesium in a monodentate mode. The analysis of the exchange processes of the water molecules in the first and second hydration shell of Mg2+ shows that the HCO3− or CO32− ligands affect the dynamics of the Magnesium coordination spheres by making its hydration shell more “labile”. Furthermore, molecular dynamics simulations of the non-associated Mg2+/Cl− pair in water suggest that, despite negligible differences in the coordination spheres of Mg2+, the chloride anion has a significant influence on the water exchange rates in the second hydration shell of Mg2+.

a gas phase solvent effect the role of water molecules in the conversion of the homg co2 adduct ion to the Magnesium Bicarbonate ion mg o2coh
International Journal of Mass Spectrometry, 2006Co-Authors: Simon PetrieAbstract:Abstract Quantum chemical calculations at the CP-dG2thaw and MP2(thaw)/B4G levels of theory are reported for the bare HOMg + OCO ion resulting from addition of CO 2 to HOMg + , and to its mono-, di- and tri-hydrated forms. These calculations are used to determine bond dissociation energy (BDE) values for the (H 2 O) n (CO 2 ) i HOMg + –OH 2 ( n = 0–2; i = 0, 1) and (H 2 O) n HOMg + –OCO ( n = 0–3) bonds, as well as to ascertain the relative energies for several key stationary points on each of the HOMg + ·(H 2 O) n ·CO 2 ( n = 0–3) potential energy surfaces. Three principal findings emerge from these calculations. First, in contrast to the isoelectronic system NaOH + CO 2 → NaO 2 COH held to play a leading role in noctilucent cloud nucleation, the reaction of HOMg + + CO 2 does not result in formation of the Magnesium Bicarbonate cation Mg + O 2 COH. Second, the cumulative Mg + –ligand bond energies for complexes of HOMg + with several H 2 O and CO 2 molecules rapidly approach, and then exceed, the available Mg + recombination energy, indicating that dissociative recombination of HOMg + ·(H 2 O) n ·CO 2 (or its Bicarbonate-containing isomer Mg + O 2 COH·(H 2 O) n ) is likely to result in the production of molecular Mg-containing neutrals. Third, we find that hydration exhibits a remarkable influence on the reactivity of HOMg + with mesospheric CO 2 : addition of CO 2 to bare HOMg + does not result in Bicarbonate formation, nor do the reactions of HOMg + ·CO 2 and HOMg + ·OH 2 ·CO 2 with H 2 O, but the reaction of HOMg + ·(OH 2 ) 2 ·CO 2 with H 2 O leads to two possible Bicarbonate-containing products (H 2 O) 2 ·Mg + O 2 COH and (H 2 O) 3 ·Mg + O 2 COH. The former product channel, which involves association followed by H 2 O loss, is judged to be an unusual example of a catalytic process in which the principal contribution of the H 2 O ‘catalyst’ is steric.

hypolipidemic activity of a natural mineral water rich in calcium Magnesium and Bicarbonate in hyperlipidemic adults
Advanced Pharmaceutical Bulletin, 2014Co-Authors: Naser Aslanabadi, Babak Bakhshalizadeh, Faranak Ghaderi, Mahboob NematiAbstract:Purpose: This study compared the effects of a mineral water rich in calcium, Magnesium, Bicarbonate, and sulfate and a marketed mineral water with a composition similar to that of urban water on the lipid profile of dyslipidemic adults. Methods: In a randomized controlled trial, 32 adults received one liter of "rich mineral water" daily for one month, and 37 adults drank the same amount of normal mineral water for the same period. Changes in lipid profiles were compared separately in each studied group at the end of one month. Results: Results showed that mean cholesterol and low density lipoprotein LDL levels were significantly decreased in both studied groups after one month of drinking mineral water (P 0.05).Conclusion: A one-month intake of mineral water rich in calcium, Magnesium Bicarbonate, and sulfate decreased cholesterol and LDL levels but not TG or HDL levels in dyslipidemic adults.
