High-frequency blood flow-restricted resistance exercise results in acute and prolonged cellular stress more pronounced in type I than in type II fib…
2021
Myocellular stress with high-frequency blood flow-restricted resistance exercise (BFRRE) was investigated by measures of heat shock protein (HSP) responses, glycogen content, and inflammatory markers. Thirteen participants [age: 24 ± 2 yr (means ± SD), 9 males] completed two 5-day blocks of seven BFRRE sessions, separated by 10 days. Four sets of unilateral knee extensions to failure at 20% of one-repetition maximum (1RM) were performed. Muscle samples obtained before, 1 h after the first session in the first and second block (
Preliminary evidence of reductive stress in human cytotoxic T cells following exercise.
2018
This study investigated immunophenotypic differences in intracellular thiol redox state of peripheral blood mononuclear cells (PBMCs) isolated from trained [ n = 9, means ± SD: age 28 ± 5 yr; (body mass index) BMI 23.2 ± 2.6 kg/m2; V̇o2max (maximal oxygen intake)56.9 ± 6.1 ml·kg−1·min−1] and recreationally active (RA, n = 11, means ± SD: age 27 ± 6 yr; BMI 24.2 ± 3.7 kg/m2; V̇o2max 45.1 ± 6.4 ml·kg−1·min−1) participants before and after a maximal aerobic exercise tolerance test. Blood samples were taken before (Pre), during (sample acquired at 70% maximum heart rate), immediately after (Post + 0), and 15 min postexercise (Post + 15). PBMCs were isolated, and reduced thiol analysis [fluores…
Mediterranean diet and sars-cov-2 infection: Is there any association? a proof-of-concept study
2021
The aim of this observational study was investigating the possible correlation between adherence to the Mediterranean diet (MeD) and SARS-COV-2 infection rates and severity among healthcare professionals (HCPs). An online self-administrated questionnaire (evaluating both MeD adherence and dietary habits) was filled out by HCPs working in Piedmont (Northern Italy) from 15 January to 28 February 2021. Out of the 1206 questionnaires collected, 900 were considered reliable and analyzed. Individuals who reported the SARS-COV-2 infection (n = 148) showed a significantly lower MeD score, with a lower adherence in fruit, vegetables, cereals, and olive oil consumption. In a logistic regression model…
Double-Blind, Placebo-Controlled, Randomized Trial of Selenium in Graves Hyperthyroidism.
2017
Abstract Context Supplemental selenium (Se) may affect the clinical course of Graves disease (GD). Objective Evaluate efficacy of add-on Se on medical treatment in GD. Design Double-blind, placebo-controlled, randomized supplementation trial. Setting Academic endocrine outpatient clinic. Patients Seventy untreated hyperthyroid patients with GD. Intervention Additionally to methimazole (MMI), patients received for 24 weeks either sodium selenite 300 µg/d po or placebo. MMI was discontinued at 24 weeks in euthyroid patients. Main Outcome Measures Response rate (week 24), recurrence rate (week 36), and safety. Results A response was registered in 25 of 31 patients (80%) and in 27 of 33 (82%) a…
StudentKost: a cross-sectional study assessing college students' diets: reason for concern?
2020
Abstract College students constitute a significant proportion of the young adult population in Norway. They are in their reproductive years, which is of interest regarding diet and preconception health. Our objective was to assess young college students’ diet and nutrient intake in relation to national dietary recommendations and assess the probability of inadequate micronutrient intake for both genders using the Nordic Nutrition Recommendations, and also to evaluate its consequences on preconception health and create a groundwork for future interventions on this group. At the University of Agder (UiA), we enrolled 622 students aged 18–40 years for a cross-sectional study of student's diet,…
The Gut Metagenome Changes in Parallel to Waist Circumference, Brain Iron Deposition, and Cognitive Function.
2017
Context Microbiota perturbations seem to exert modulatory effects on emotional behavior, stress-, and pain-modulation systems in adult animals; however, limited information is available in humans. Objective To study potential relationships among the gut metagenome, brain microstructure, and cognitive performance in middle-aged, apparently healthy, obese and nonobese subjects after weight changes. Design This is a longitudinal study over a 2-year period. Setting A tertiary public hospital. Patients or other participants Thirty-five (18 obese) apparently healthy subjects. Intervention(s) Diet counseling was provided to all subjects. Obese subjects were followed every 6 months. Main outcome me…
Alpha-defensins (α-Defs) in Crohn's disease: decrease of ileal α-Def 5 via permanent methylation and increase in plasma α-Def 1-3 concentrations offe…
2018
Summary An impaired expression of α-defensins (α-Defs) in the ileal mucosa and, conversely, increased levels in plasma, have been reported in Crohn's disease (CD). However, the specificity and correlation of these findings with the degree of inflammation are unclear. We aimed to characterize the concentration and utility of ileal and plasma α-Defs in CD and to analyse a potential epigenetic mechanism of α-Def expression. Peripheral blood samples and ileal biopsies were obtained from patients at disease onset (aCD), from those who achieved remission (iCD) and from two control groups (healthy controls and non-CD-aetiology ileitis patients). Plasma α-Defs 1–3 and 4 were detected by enzyme-link…
Are Mitochondrial Fusion and Fission Impaired in Leukocytes of Type 2 Diabetic Patients?
2016
Mitochondrial fusion/fission alterations have been evaluated in different tissues of type 2 diabetic (T2D) patients. However, it is not known whether mitochondrial dynamics is disturbed in the leukocytes of T2D patients and whether glycemic control affects its regulation. Anthropometric and metabolic parameters in 91 T2D patients (48 with glycated hemoglobin [HbA1c]6.5% and 43 with HbA1c6.5%) were characteristic of the disease when compared with 78 control subjects. We observed increased reactive oxygen species production in leukocytes from diabetic patients, together with a reduced mitochondrial oxygen consumption rate, especially in poorly controlled patients. Mitochondrial fusion was red…
Role of Haptoglobin as a Marker of Muscular Improvement in Patients with Multiple Sclerosis after Administration of Epigallocatechin Gallate and Incr…
2021
Here, we report on the role of haptoglobin (Hp), whose expression depends on the synthesis of interleukin 6 (IL-6), related to the pathogenesis of multiple sclerosis (MS), as a possible marker of muscle improvement achieved after treatment with the polyphenol epigallocatechin gallate (EGCG) and an increase in the ketone body beta-hydroxybutyrate (BHB) in the blood. After 4 months of intervention with 27 MS patients, we observed that Hp does not significantly increase, alongside a significant decrease in IL-6 and a significant increase in muscle percentage. At the same time, Hp synthesis is considerably and positively correlated with IL-6 both before and after treatment
Morphometric and kinematic sperm subpopulations in split ejaculates of normozoospermic men
2016
This study was designed to analyze the sperm kinematic and morphometric subpopulations in the different fractions of the ejaculate in normozoospermic men. Ejaculates from eight normozoospermic men were collected by masturbation in three fractions after 3-5 days of sexual abstinence. Analyses of sperm motility by computer-assisted sperm analysis (CASA-Mot), and of sperm morphometry by computer-assisted sperm morphometry analysis (CASA-Morph) using fluorescence were performed. Clustering and discriminant procedures were performed to identify sperm subpopulations in the kinematic and morphometric data obtained. Clustering procedures resulted in the classification of spermatozoa into three kine…
