AI Article Synopsis
- Patients with type-2 diabetes (T2DM) show significantly higher tissue sodium content in both muscle and skin compared to those with primary hypertension, suggesting a potential link between sodium levels and diabetic conditions.
- The study utilized a 3.0 T MRI to assess sodium content in patients with T2DM and those with primary hypertension, finding statistically significant differences even after considering various confounding factors.
- These findings indicate the need for therapeutic strategies aimed at reducing tissue sodium levels in T2DM patients, as high sodium content may be associated with organ damage.
Article Abstract
Background: Tissue sodium content by Na magnetic resonance imaging (MRI) has been found to be increased in arterial hypertension. We analyzed whether tissue sodium content is increased in patients with type-2 diabetes (T2DM).
Methods: Patients with T2DM were compared to those with primary hypertension. Patients with T2DM were off any antidiabetic and hypertensive patients off any antihypertensive therapy for at least 4 weeks. Skin and muscle sodium content was assessed non-invasively with a 3.0 T clinical MRI system (Magnetom Verio, Siemens Health Care, Erlangen, Germany) in each patient.
Results: In patients with T2DM (N = 59) we observed significantly greater muscle sodium content (diabetes: 20.6 ± 3.5 vs hypertension: 16.3 ± 2.5 mmol/l, p < 0.001) and skin sodium content (diabetes: 24.5 ± 7.2 vs hypertension: 20.6 ± 5.7 mmol/l, p = 0.01) than in those with primary hypertension (N = 33). When potential confounders (age, body mass index, gender, systolic and diastolic blood pressure, estimated glomerular filtration rate) were entered in a covariance analysis, both skin sodium content (p = 0.037) and muscle sodium content (p < 0.001) were still clearly elevated.
Conclusion: Patients with T2DM have greater skin and muscle sodium content. These are the first known data to demonstrate increased tissue sodium content in patients with T2DM, measured by Na magnetic resonance imaging. Since tissue sodium content is related to organ damage, therapeutic intervention should aim at reducing tissue sodium content.

Hydrogels, three-dimensional polymeric networks capable of absorbing and retaining significant amounts of aqueous solution, offer a promising platform for controlled release of desired compounds. In this study, we explored the effects of urea delivery through galactoxyloglucan-sodium alginate hydrogels on the phenotypic and metabolic responses of , a vital oilseed and vegetable crop. The experiments were conducted with four treatments: control (without hydrogel beads and urea), direct urea supplementation (U), hydrogel beads with urea (HBWU), and hydrogel beads without urea (HBWOU).

To explore the effects of salt-tolerance gene accumulation on salt tolerance in transgenic plant, we used four types of plant expression vector (N27, N28, N29, and N30) carrying mtlD, mtlD + gutD, mtlD + gutD + BADH, mtlD + gutD + BADH + sacB genes respectively, to transform tobacco through Agrobacterium-mediated method. Transgenic lines were identified through polymerase chain reaction (PCR) detection. Transgenic lines and non-transgenic plant (CK) were subjected to 6‰ sodium chloride solution stress; then, fluorescence quantitative PCR (FQ-PCR) and salt tolerance indexes were used to assess characteristics.

The crosslinked porous corn starch was prepared by two steps: the native corn starch was hydrolyzed by α-amylase and glucoamylase, then the porous corn was crosslinked by sodium trimetaphosphate (STMP). The morphology and size of granules, spherulites, crystal type, molecular structure, swelling properties, thermal stability and adsorption properties of the crosslinked porous starch were investigated. The results indicated that a lot of holes formed in the porous starch, and the particle size of starch granules decreased.

Background: The antioxidant capacity of anthocyanins (AC) rapidly degrades during storage, highlighting the need for their stabilization. The conformational properties and high proline content of sodium caseinate (NaCAS), combined with the formation of NaCAS microgels in the presence of tara gum (TG) and acid gelation, suggest its potential as an effective stabilizing or encapsulating agent of AC.
Results: Spectrofluorimetric results suggest the formation of a complex between NaCAS and AC.
