A Comprehensive Overview on Necessity and Strategies of Salt Intake Reduction in the Population [PDF]

Taṣvīr-i salāmat, 2017
Non-communicable diseases (NCDs) have become a major public health problem not only in developed countries, but also in developing countries; as cardiovascular disease is considered to be the leading cause of death in the world.

Characterization of the channel diffusion in a sodium tetrasilicate glass via molecular-dynamics simulations [PDF]

, 2002
We study the structural and dynamical characteristics of the sodium atoms inside and outside the ``diffusion channels'' in glassy Na$_2$O-4SiO$_2$ (NS4) using classical molecular dynamics. We show that on average neither energetic arguments nor local environment considerations can explain the increased density of sodium atoms inside the subspace made ...

Effect of lower sodium intake on health: systematic review and meta-analyses [PDF]

, 2013
Objective To assess the effect of decreased sodium intake on blood pressure, related cardiovascular diseases, and potential adverse effects such as changes in blood lipids, catecholamine levels, and renal function.

Unlocking the potential of tumor‐derived DNA in urine for cancer detection: methodological challenges and opportunities

Molecular Oncology, EarlyView.
Urine is a rich source of biomarkers for cancer detection. Tumor‐derived material is released into the bloodstream and transported to the urine. Urine can easily be collected from individuals, allowing non‐invasive cancer detection. This review discusses the rationale behind urine‐based cancer detection and its potential for cancer diagnostics ...

Evolution of cation binding in the active sites of P-loop nucleoside triphosphatases in relation to the basic catalytic mechanism

eLife, 2018
The ubiquitous P-loop fold nucleoside triphosphatases (NTPases) are typically activated by an arginine or lysine ‘finger’. Some of the apparently ancestral NTPases are, instead, activated by potassium ions.

Matrix controlled channel diffusion of sodium in amorphous silica [PDF]

, 2002
To find the origin of the diffusion channels observed in sodium-silicate glasses, we have performed classical molecular dynamics simulations of Na$_2$O--4SiO$_2$ during which the mass of the Si and O atoms has been multiplied by a tuning coefficient. We observe that the channels disappear and that the diffusive motion of the sodium atoms vanishes if ...

Subpar reporting of pre‐analytical variables in RNA‐focused blood plasma studies

Molecular Oncology, EarlyView.
Pre‐analytical variables strongly influence the analysis of extracellular RNA (cell‐free RNA; exRNA) derived from blood plasma. Their reporting is essential to allow interpretation and replication of results. By evaluating 200 exRNA studies, we pinpoint a lack of reporting pre‐analytical variables associated with blood collection, plasma preparation ...

Evaluation of electrolyte status of sodium, potassium and magnesium, and fasting blood sugar at the initial admission of individuals with COVID-19 without underlying disease in Golestan Hospital, Kermanshah

New Microbes and New Infections, 2020
We examined electrolyte imbalance and blood sugar levels in patients with COVID-19 who had no underlying disease. This cross-sectional study in a clinical center was performed in Kermanshah, west of Iran. All patients who had a record of magnesium (Mg2+),

Central Hemodynamic Parameters are Altered in Resistant Hypertensive Individuals

Artery Research, 2019
Background: Systemic arterial hypertension (SAH) is one of the major risk factors related to the development of cardiovascular diseases (CVD). Sodium intake is linked to elevated blood pressure and can be estimated by 24-h urinary sodium excretion.

Sodium diffusion through amorphous silica surfaces: A molecular dynamics study [PDF]

, 2003
We have studied the diffusion inside the silica network of sodium atoms initially located outside the surfaces of an amorphous silica film. We have focused our attention on structural and dynamical quantities, and we have found that the local environment of the sodium atoms is close to the local environment of the sodium atoms inside bulk sodo-silicate
