3. Acceptance of Low-Sodium Hospital Diet by Cardiac Patients: A Randomized Controlled Crossover Trial
Abstract Background Cardiovascular diseases are the major cause of hospitalization. Dietary salt restriction is indicated as part of clinical treatment, however, it is not always well accepted by the patients, resulting in low food intake and malnutrition. Objective To compare acceptance of a low-sodium diet cooked with salt with a standard low-sodium di

4. The effects of macronutrients composition on hormones and substrates during a meal tolerance test in drug-naive and sitagliptin-treated individuals with type 2 diabetes: a randomized crossover study
ABSTRACT Objectives: To evaluate the effect of sitagliptin treatment in early type 2 diabetes mellitus (T2DM) and the impact of different macronutrient compositions on hormones and substrates during meal tolerance tests (MTT). Materials and methods: Half of the drug-naive patients with T2DM were randomly assigned for treatment with 100 mg of sitagliptin, q

5. Effects of Physical Exercise on Lipid and Inflammatory Profile of Women Using Combined Oral Contraceptive: A Cross-Over Study
Abstract Background: The use of combined oral contraceptives (COC) is a risk factor for atherosclerotic disease, and physical exercise can minimize this condition. Objective: To verify if high intensity interval training (HIIT) promotes changes in the lipid and inflammatory profile of women using COC. Methods: Sequential crossover study with women aged 20

6. Preoperative fasting for the infusion of “yerba mate”: a randomized clinical trial with ultrasound evaluation of gastric contents
Abstract Background The traditional infusion of “yerba mate” is widely consumed in South America and exported to countries around the world. Although generally considered a “clear fluid”, there is no data to date on the gastric emptying time of yerba mate and safe preoperative fasting intervals. The objective of this study was to evaluate the gastri

10. Autonomic function may not modulate irisin release in healthy adults: findings from a randomized cross-over study
ABSTRACT Objective Autonomic nervous system, especially the sympathetic nervous system, may stimulate the expression of peroxisome proliferator-activated receptor γ coactivator-1α, which regulates irisin. This study aimed to explore whether there was any association between autonomic function as assessed by heart rate related indices and irisin release f

11. USO DA TEORIA DO FUNCIONAL DE DENSIDADE NA ANÁLISE DE SPIN CROSSOVER EM AULAS DE QUÍMICA INORGÂNICA
Spin crossover is a property found in some coordination compounds formed by the first series of transition metals with d4-d7 configuration. These complexes, when stimulated by an external factor (temperature, light, etc.), can be converted from their low spin states to high spin states, or vice versa. However, this issue is not addressed in the Inorganic Che

12. Anti-biofilm and anti-inflammatory effect of a herbal nanoparticle mouthwash: a randomized crossover trial
Abstract Laboratory evidence has demonstrated the antimicrobial effect of Melaleuca alternifolia (MEL) against oral microorganisms. This randomized, double-blind, crossover clinical trial, compared the anti-biofilm and anti-inflammatory effects of MEL nanoparticles with 0.12% chlorhexidine gluconate (CHX) on biofilm-free (BF) and biofilm-covered (BC) surface
