Mitochondrial complex I impairment in leukocytes from type 2 diabetic patients.
2011
Diabetes is associated with oxidative stress. This study evaluated the rates of oxidative stress and mitochondrial impairment in type 2 diabetes patients. The study population consisted of 182 diabetic patients and 50 body-composition- and age-matched controls. We assessed anthropometric and metabolic parameters and mitochondrial function by evaluating mitochondrial oxygen (O2) consumption, reactive oxygen species (ROS) production, glutathione (GSH) levels, GSH/GSSG ratio, mitochondrial membrane potential, and mitochondrial complex I activity in polymorphonuclear cells from diabetes type 2 patients. We found an increase in waist circumference and augmented serum levels of triglycerides, pro…
Comparative study of post-natal retinal vascular development in mice models of iPLA2 inhibition and plasmalogen deficiency
2012
Purpose: Plasmalogens are particular phospholipids characterized by the presence of a vinyl-ether bond and of a polyunsaturated fatty acid (PUFA) at sn-1 and sn-2 positions of glycerol, respectively. Even if the plasmalogen content of organs and tissues is well documented, their biological functions are still enigmatic. Plasmalogen deficiency in DAPAT-/- mice leads to developmental abnormalities in retinal vasculature (Acar et al, ARVO 2007 E-Abstract 2978) and to persistent hyaloïd arteries. We hypothesize that plasmalogens regulate retinal vascular development through the liberation of PUFA by a plasmalogen-specific calcium-independent phospholipase A2 (iPLA2). We have performed a compara…
Inflammation et immunité : implications dans l’obésité et le diabète de type 2
2006
The evidences have been increasingly accumulated on the implication of inflammatory mediators like tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in the pathological states related to insulin resistance like obesity, type 2 diabetes and atherosclerosis. There seems a link between insulin resistance and these pro-inflammatory agents, secreted by macrophages and adipocytes. Th (helper) cells are differentiated into either Th1 or Th2 phenotypes. It is generally considered that Th1 phenotype is pro-inflammatory whereas Th2 phenotype exerts anti-inflammatory (protective) effects. The upregulation of Th1 phenotype may aggravate these pathologies. One of the adipokines, i.e., adiponectin…
Exposure to ototoxic agents and hearing loss: A review of current knowledge
2014
Several experimental and clinical studies have shown that a variety of ototoxic agents (such as drugs, industrial chemicals and noise) can cause sensorineural hearing loss. The most common ototoxic drugs used in clinical practice include: aminoglycoside and macrolide antibiotics, quinoline anti-malarials, platinum analog antineoplastics, loop diuretics, and acetylsalicylic acid. Among chemical agents with potential ototoxic properties are: organic solvents, heavy metals, organotins, nitriles, asphyxiants, and pesticides/herbicides. Acoustic exposure to high intensity and/or prolonged noise can also cause permanent threshold shifts in auditory perception. Ototoxic agents can influence audito…
Isokinetic Profile of Elite Serbian Female Judoists
2021
Elite judo athletes undergo vigorous training to achieve outstanding results. In pursuit of achieving competitive success, the occurrence of injuries amongst judo athletes is not rare. The study aimed to perform a knee flexors and extensors isokinetic torque analysis in elite female judo athletes. Fifty-eight elite female judo athletes of the Serbian national team (21.02 ± 3.11 years
The energetic cost of humoral immunity in the Collared Dove, Streptopelia decaocto : is the magnitude sufficient to force energy-based trade-offs?
2005
International audience; 1. Energy saving is often suggested as the basis of a resource trade-off between immunocompetence and other fitness-relevant traits. This suggests that the energetic cost of an immune response is significant and sufficient to force trade-offs. To date, few studies have investigated the energetic cost of the humoral component of the immune system in birds and furthermore, existing results are contradictory. 2. We addressed this question through two experiments. In experiment 1, the basal metabolic rate (BMR) of Collared Doves, Streptopelia decaocto , challenged with sheep red blood cells (SRBC) was compared with the BMR of control birds. The energetic cost of immunity…

Validity and repeatability of the Pediatric Allergy Questionnaire for Athletes (AQUAped) for the screening of atopy.
2020
BACKGROUND High atopy prevalence has been reported in athletes. Having an age-specific questionnaire for predicting atopy is important for an optimal management of young athletes. The study objectives were as follows: (i) developing a scoring system for the Pediatric Allergy Questionnaire for Athletes (AQUAped); (ii) identifying the optimal age target within the range 7-14 years; (iii) assessing AQUAped validity and repeatability in the identified target population. METHODS A total of 133 young athletes (age 7-14 years) were recruited. Following a screening visit, the participants filled AQUAped at baseline (T0) and after 7 days (T1), concomitantly undergoing skin prick testing. Using atopy…
Cohort profile: Thrombolysis in Ischemic Stroke Patients (TRISP): a multicentre research collaboration
2018
PurposeThe ThRombolysis in Ischemic Stroke Patients (TRISP) collaboration aims to address clinically relevant questions about safety and outcomes of intravenous thrombolysis (IVT) and endovascular thrombectomy. The findings can provide observational information on treatment of patients derived from everyday clinical practice.ParticipantsTRISP is an open, investigator-driven collaborative research initiative of European stroke centres with expertise in treatment with revascularisation therapies and maintenance of hospital-based registries. All participating centres made a commitment to prospectively collect data on consecutive patients with stroke treated with IVT using standardised definiti…
Molecular and Translational Classifications of DAMPs in Immunogenic Cell Death
2015
The immunogenicity of malignant cells has recently been acknowledged as a critical determinant of efficacy in cancer therapy. Thus, besides developing direct immunostimulatory regimens, including dendritic cell-based vaccines, checkpoint-blocking therapies, and adoptive T-cell transfer, researchers have started to focus on the overall immunobiology of neoplastic cells. It is now clear that cancer cells can succumb to some anticancer therapies by undergoing a peculiar form of cell death that is characterized by an increased immunogenic potential, owing to the emission of the so-called "damage-associated molecular patterns" (DAMPs). The emission of DAMPs and other immunostimulatory factors by…
