Inflammation and endothelial activation are linked to renal function in long-term kidney transplantation
2006
The aim of this study was to investigate the relationships between inflammation and adhesion molecules in long-term kidney transplantation. We measured serum concentrations of tumor necrosis factor-alpha (TNFalpha) and intercellular and vascular cell adhesion molecules (ICAM-1 and VCAM-1) in 35 renal transplant recipients (mean age of transplantation 5 +/- 3 years) and in 35 chronic renal insufficiency (CRI) patients; twenty-six healthy subjects were enrolled as controls. Transplanted showed higher values than controls of TNFalpha (P < 0.0001), ICAM-1 (P < 0.0001), and VCAM-1 (P < 0.0001). CRI group as well exhibited higher concentrations than controls of TNFalpha (P < 0.0001), ICAM-1 (P < …
Blood Flow Restriction Alters Motor Unit Behavior During Resistance Exercise.
2019
AbstractWe aimed to determine whether blood flow restriction (BFR) alters the characteristics of individual motor units during low-intensity (LI) exercise. Eight men (26.0±3.8 yrs) performed 5 sets of 15 knee extensions at 20% of one-repetition maximum (with and without BFR). Maximal isometric voluntary contractions (MVC) were performed before and after exercise to quantify force decrement. Submaximal isometric voluntary contractions were additionally performed for 18 s, matching trapezoidal target-force trajectories at 40% pre-MVC. EMG activity was recorded from the vastus lateralis muscle. Then, signals were decomposed to extract motor unit recruitment threshold, firing rates and action p…
Smoking, diabetes, blood hypertension: possible etiologic role for Peyronie’s disease? Analysis in 279 patients with a control group in Sicily
2015
Objective: To assess the proportion of patients with Peyronie’s Disease (PD) and the possible association with its potential risk factors in the general population of the central and western Sicily in our weekly andrological outpatient clinic. Materials and methods: We recruited a sample of 279 consecutive patients consulting our andrological outpatient clinic. Two arms were created: the first one composed by PD patients (men with symptoms suggestive for PD), the second one composed by patients with other andrological diseases (control arm). For each patient we evaluated the age, cigarette smoking, diabetes, blood hypertension and erectile function. In the PD arm we administered validated q…
Sports massage with ozonised oil or non-ozonised oil: Comparative effects on recovery parameters after maximal effort in cyclists
2013
Abstract OBJECTIVES: To study the effects of passive rest (PR) and sports massage with (SMOZO) and without (SM) ozonised oil on sports performance psycho-physiological indices in competitive amateur cyclists after 3 pre-fatiguing Wingate cycle and post-recovery ramp tests. DESIGN: An intra-subjects experimental design with repeated measures. SETTING: Department of Human Anatomy and Physiology, University of Padua. PARTICIPANTS: Fifteen male competitive cyclists (age: 27 ± 3.5 years, body weight: 77.6 ± 8.3 kg, height: 178 ± 7.7 cm) were studied. MAIN OUTCOME MEASURES: Subjects' power output (P), heart rate (HR), Visual Analogue Scale (VAS) score and blood lactate (BL) clearance in response …
Circulating IGF-I is associated with fitness and health outcomes in a population of 846 young healthy men
2011
Abstract Context Insulin-like growth factor-I (IGF-I) is thought to mediate many of the beneficial outcomes of physical activity. While IGF-I has previously been shown to be positively related with aerobic fitness, few studies have examined IGF-I relationships with other fitness and health parameters. The robustness of IGF-I as a biomarker of fitness and health has yet to be fully determined. Objective To determine the association of circulating IGF-I with fitness, body composition and health parameters in young, healthy men. Design and subjects A cross-section of 846 young, healthy Finnish men (25 ± 5 yr, 180 ± 6 cm, 81 ± 13 kg). Subjects were divided into quintiles of IGF-I concentrations…
Are abdominal obesity and body mass index independent predictors of hemorheological parameters?
2012
There is an association between obesity and rheological blood behavior [2, 4–7]. In this sense we have read with interest the recently published article by Brun et al. [1] in this journal. The authors evaluate, in a population of 430 subjects, the relationship between abdominal obesity and body mass index (BMI) with blood viscosity, and conclude that both anthropometric parameters are associated with increased blood viscosity but by different mechanisms, where the waist to hip ratio is a better predictor for blood viscosity than BMI. It is striking that in this study the authors do not indicate the variables included in the stepwise multivariate regression model, where plasma lipids, glucos…
Gender-specific anthropometric markers of adiposity, metabolic syndrome and visceral adiposity index (VAI) in patients with obstructive sleep apnea
2013
Obstructive sleep apnea often coexists with visceral adiposity and metabolic syndrome. In this study, we analysed gender-related differences in anthropometrics according to sleep apnea severity and metabolic abnormalities. In addition, the visceral adiposity index, a recently introduced marker of cardiometabolic risk, was analysed. Consecutive subjects with suspected obstructive sleep apnea (n = 528, 423 males, mean age ± standard deviation: 51.3 ± 12.8 years, body mass index: 31.0 ± 6.2 kg m(-2) ) were studied by full polysomnography (apnea-hypopnea index 43.4 ± 27.6 h(-1) ). Variables of general and visceral adiposity were measured (body mass index, neck, waist and hip circumferences, wai…
Prevalence of dyslipidemia and associated risk factors in Turkish adults.
2013
Background and Objectives Dyslipidemia is a modifiable major risk factor for coronary heart disease. The objective of this study was to determine the prevalence of dyslipidemia among Turkish adults and its associations with other cardiovascular risk factors. Methods This study included 4309 people ages 20 to 83 years old from 7 provinces of Turkey. People from the city centers, districts, and villages were selected by a stratified sampling method. Weight, height, and waist and hip circumferences were measured. Blood samples were obtained to determine glucose, total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and triglycerides …
Muscle inactivity is adversely associated with biomarkers in physically active adults.
2015
PURPOSE While the lack of muscular activity is a proposed trigger for metabolic alterations, this association has not been directly measured. We examined the associations between EMG-derived muscle inactivity and activity patterns and cardiometabolic biomarkers in healthy, physically active adults. METHODS Data for this cross-sectional study were pooled from two studies (EMG24 and InPact), resulting in a sample of 150 individuals without known chronic diseases and with high-quality EMG data (female n = 85, male n = 65, age = 38.8 ± 10.6 yr, body mass index = 23.8 ± 3.1 kg·m⁻²). EMG was measured during one to three typical weekdays using EMG shorts, measuring quadriceps and hamstring muscle …
Free amino acid pool and muscle protein balance after resistance exercise.
2003
The aim of this study was to assess the effects of a resistance exercise session (RES) on free amino acid concentrations and protein synthesis and breakdown of the vastus lateralis (VL) muscle during recovery in male subjects.Both the exercise group (EG) and the control group (CG) consisted of six healthy physically active men. On the experiment day in fasting conditions, a stable isotopic tracer of L-[ring-2H(5)] phenylalanine was infused and EG started a heavy 50-min hypertrophic RES for lower extremities after 55 min of infusion. At the same time, CG was at rest. During recovery of 195 min after RES, several blood samples were drawn from the femoral artery (FA) and the femoral vein (FV) …
