Biomarkers of oxidation, inflammation and intestinal permeability in persons with diabetes mellitus with parenteral nutrition: A multicenter randomized trial.

Background And Aims: Parenteral nutrition (PN) composition could play a role in the management of systemic inflammatory response and intestinal barrier disruption. We aimed to evaluate changes in biomarkers of inflammation, oxidative status and intestinal permeability in patients with type 2 diabetes mellitus (T2DM) who received different PN lipid formulas.

Methods: This was a prospective study, including 94 patients with T2DM who received omega (n)-3 polyunsaturated fatty acids (PUFA)-enriched PN, a mixture of medium and long chain triglycerides (MCT/LCT) PN, or an olive oil-based PN.

Normal Hemodynamic Response to Exercise.

Exercise pulmonary hypertension has been invasively defined as mean pulmonary artery pressure/cardiac output slope greater than 3 mm Hg/L/min. Recent advances suggest the sustainable role of exercise Doppler echocardiography for the study of the right heart and pulmonary circulation unit (RH-PCU). Herein, the authors review the invasive versus non-invasive monitoring of the RH-PCU response to exercise in healthy subjects.

Exotoxins secreted by Clostridium septicum induce macrophage death: Implications for bacterial immune evasion mechanisms at infection sites.

The induction of macrophage death is considered a potential mechanism by which components secreted by Clostridium septicum are used to evade the innate immune response and cause tissue damage. This study aimed to determine the effects of partially purified fractions of extracellular proteins secreted by C. septicum on the death of mouse peritoneal macrophages.

Operation model of a skew-symmetric split-crystal neutron interferometer.

The observation of neutron interference using a triple Laue interferometer formed by two separate crystals opens the way to the construction and operation of skew-symmetric interferometers with extended arm separation and length. The specifications necessary for their successful operation are investigated here: most importantly, how the manufacturing tolerance and crystal alignments impact the interference visibility. In contrast with previous studies, both incoherent sources and the three-dimensional operation of the interferometer are considered.

Modulation of miR-29a and miR-29b Expression and Their Target Genes Related to Inflammation and Renal Fibrosis by an Oral Nutritional Supplement with Probiotics in Malnourished Hemodialysis Patients.

Malnutrition is prevalent in patients with chronic kidney disease (CKD), especially those on hemodialysis. Recently, our group described that a new oral nutritional supplement (ONS), specifically designed for malnourished (or at risk) hemodialysis patients with a "similar to the Mediterranean diet" pattern, improved caloric-protein intake, nutritional status and biomarkers of inflammation and oxidation. Our aim in this study was to evaluate whether the new ONS, associated with probiotics or not, may produce changes in miRNA's expression and its target genes in malnourished hemodialysis patients, compared to individualized diet recommendations.
