Sprint and endurance training in relation to redox and inflammatory status and biomarkers of aging in master athletes
2020
Purpose Studies have shown a positive influence of intense athletic training on several biomarkers of aging, but it remains unclear whether this influence is dependent of exercise-training-mode. This study compared redox balance, cytokine levels and biomarkers of aging between master sprinters and endurance athletes, as well as in young and middle-aged individuals as controls. Methods Participants were male master sprinters (SA, 50±8.9yrs; n=13) and endurance runners (EA, 53±8.2yrs; n=18) with remarkable athletic experience (∼25yrs of practice), besides untrained young (YC, 22.7±3.9yrs; n=17) and age-matched controls (MC, 45.5±9.8yrs; n=12). Anamnesis, anthropometrics, biomarkers of aging, …
The FGF-2/FGFRs neurotrophic system promotes neurogenesis in the adult brain.
2009
Neurogenesis occurs in two regions of the adult brain, namely, the subventricular zone (SVZ) throughout the wall of the lateral ventricle and the subgranular zone (SGZ) of the dentate gyrus (DG) in hippocampal formation. Adult neurogenesis requires several neurotrophic factors to sustain and regulate the proliferation and differentiation of the adult stem cell population. In the present review, we examine the cellular and functional aspects of a trophic system mediated by fibroblast growth factor-2 (FGF-2) and its receptors (FGFRs) related to neurogenesis in the SVZ and SGZ of the adult rat brain. In the SVZ, FGF-2 is expressed in GFAP-positive cells of SVZ but is not present in proliferati…
POTENTIAL NEW GENETIC AND BIOCHEMICAL MARKERS OF CHRONIC KIDNEY FAILURE
2017
disease (CKD) is an important source of long-term morbidity and mortality. It has been estimated that CKD affects more than 20 million people in the United States. Given that most patients are asymptomatic until the disease has significantly progressed, they remain unaware of the condition. Thus, it is essential to have clinical practice guidelines (BIOMARKERS aimed at early detection, evaluation, diagnosis, and treatment of this condition.

Fibroblast Growth Factor-21 (FGF-21) enhances mitochondrial functions and increases the activity of PGC-1α in human dopaminergic neurons.
2014
FGF-21 è un fattore di crescita ad azione endocrina principalmente espresso nel fegato con funzioni metaboliche; induce a livello epatico e in altri tessuti incremento di PGC1, ma le sue funzioni a livello cerebrale sono ancora sconosciute. PGC1 è espresso anche nel cervello dove mostra azione neuroprotettiva in neuroni dopaminergici in modelli animali di morbo di Parkinson. Scopo della ricerca era indagare possibili correlazioni tra le due proteine a livello cerebrale. I dati mostrano che FGF-21 induce attivazione di PGC1 mediante la deacetilasi Sirtuina-1 NAD+ dipendente, in neuroni dopaminergici e un incremento dell’attività respiratoria mitocondriale. FGF-21 risulta espresso nel cerv…
FGF-2/FGFR1 neurotrophic system expression level and its basal activation do not account for the age-dependent decline of precursor cell proliferatio…
2010
It is largely accepted that neurogenesis in the adult brain decreases with age and reduced levels of local neurotrophic support is speculated to be a contributing factor. Among neurotrophic factors involved on neurogenesis, we focused our attention on the neurotrophic system fibroblast growth factor-2 (FGF-2) and its receptor FGFR1, a potent modulator of precursor cell proliferation. In the present work, we aimed to analyse if potential age-dependent changes of the FGF-2/FGFR1 neurotrophic system may give account for the age-dependent decline of precursor cell proliferation in the neurogenic region of the subventricular zone (SVZ) in the rat brain. Using in situ hybridization and western bl…
Acute intermittent nicotine treatment induces fibroblast growth factor-2 in the subventricular zone of the adult rat brain and enhances neuronal prec…
2007
Abstract Over the past years, evidence has accumulated that stem cells are present in the adult brain, and generate neurons and/or glia from two active germinal zones: the subventricular zone (SVZ) of the lateral ventricles and the subgranular zone (SGZ) of the dentate gyrus of the hippocampus. This study shows that acute intermittent nicotine treatment significantly enhances neuronal precursor cell proliferation in the SVZ of adult rat brain, but not in the SGZ of the hippocampus, and pre-treatment with mecamylamine, a nonselective nAChR antagonist, blocks the enhanced precursor proliferation by nicotine. This effect is supported by up-regulation of fibroblast growth factor-2 (FGF-2) mRNA …
Effects of massage on the expression of proangiogenic markers in rat skin
2018
Introduction. Massage is a physiotherapeutic treatment, commonly used in both therapy and restoration of normal body functions. The aim of this work was to determine the effects of skin massage on stimulating the expression of angiogenesis-initiating factors, i.e. VEGF-A, FGF-2 (bFGF) and CD34 and on skin regeneration processes. Material and methods. The study was conducted on 48 Buffalo strain rats, randomly divided into two groups. In the first group (M, the massaged group), massage was applied five times a week for 7 weeks. In the second study group (C, the control group), the massage was omitted. Massage consisted of spiral movements at the plantar surface of skin for 5 min on each rear…
