A freeze-and-thaw-induced fragment of the microtubule-associated protein tau in rat brain extracts: implications for the biochemical assessment of neurotoxicity.

Tau is a microtubule-associated protein (MAP) responsible for controlling the stabilization of microtubules in neurons. Tau function is regulated by phosphorylation. However, in some neurological diseases Tau becomes aberrantly hyperphosphorylated, which contributes to the pathogenesis of neurological diseases, known as tauopathies.

Antibody Fragments as Tools for Elucidating Structure-Toxicity Relationships and for Diagnostic/Therapeutic Targeting of Neurotoxic Amyloid Oligomers.

The accumulation of amyloid protein aggregates in tissues is the basis for the onset of diseases known as amyloidoses. Intriguingly, many amyloidoses impact the central nervous system (CNS) and usually are devastating diseases. It is increasingly apparent that neurotoxic soluble oligomers formed by amyloidogenic proteins are the primary molecular drivers of these diseases, making them lucrative diagnostic and therapeutic targets.

The second aim was to evaluate if there is an association between serum free fatty acids, inflammation and cardiometabolic biomarkers in obese adolescents with and without metabolic syndrome submitted to a long-term interdisciplinary therapy. The study involved 108 postpuberty obese adolescents, who were divided according to metabolic syndrome (MetS) diagnosis: MetS (n=32) and Non-MetS (n=76).

The potential of phototherapy to reduce body fat, insulin resistance and "metabolic inflexibility" related to obesity in women undergoing weight loss treatment.

Background And Objective: The metabolic flexibility is often impaired in diseases associated with obesity, and many studies are based on the hypothesis that dysfunction in peripheral tissues such as skeletal muscle, liver and adipose tissue represent the etiology of development of metabolic inflexibility. Experimental evidence shows that the use of phototherapy combined with exercise was effective in controlling the lipid profile, reducing the mass of adipose tissue, suggesting increased metabolic activity and changes in lipid metabolism. However, we found few data in the literature involving the use of phototherapy in association to physical training in the obese population.

The role of multicomponent therapy in the metabolic syndrome, inflammation and cardiovascular risk in obese adolescents.

Obesity is characterised by low-grade inflammation, which increases the metabolic syndrome (MetS) and cardiovascular risks. The aim of the present study was to verify the role of multicomponent therapy in controlling the MetS, inflammation and carotid intima-media thickness (cIMT) in obese adolescents. The second aim was to investigate the relationships between adipokines, the MetS parameters and cIMT.

Cut-off values of waist circumference to predict metabolic syndrome in obese adolescents.

Introduction: Metabolic syndrome (MetS) is a constellation of metabolic alteration related to abdominal obesity, inflammation and insulin resistance, which increase cardiovascular disease and mortality. The aims of the present study were to identify the prevalence of comorbidities and altered parameters in obese adolescents with and without MetS, and determine cut-off points of waist circumference to predict MetS.

Methods: 195 obese adolescents were recruited and divided according to MetS diagnosis based on IDF criteria.

Beneficial effects of a multifaceted 1-year lifestyle intervention on metabolic abnormalities in obese adolescents with and without sleep-disordered breathing.

Obesity is considered a chronic subinflammatory disease and is a risk factor for many diseases such as sleep-disordered breathing (SDB). Although the interaction between obesity and sleep has been explored, not much is known about SDB in the adolescent population. Thus, the aims of this study were, first, to verify the effect of 1 year of interdisciplinary therapy on inflammatory markers in SDB and without SDB and, second, to investigate the influence of SDB on the result of the therapy by comparing these groups.

Association of nonalcoholic fatty liver disease with cardiovascular risk factors in obese adolescents: the role of interdisciplinary therapy.

Background: Obesity is associated with several cardiovascular risk factors, including nonalcoholic fatty liver disease (NAFLD). These risk factors can induce changes in the arteries such as an increase in the carotid intima-media thickness (cIMT), which contributes to the early development of atherosclerosis.

Objective: To determine whether NAFLD is associated with an atherogenic lipid profile, inflammatory markers, or cIMT in obese adolescents and to compare the effects of therapeutic lifestyle changes in NAFLD and non-NAFLD groups.

The aim of this study was to investigate the role of a medically supervised, multidisciplinary approach, on reduction in the prevalence of obesity related comorbidities, inflammatory profile, and neuroendocrine regulation of energy balance in a sample of obese adolescents. A total of 97 postpuberty obese adolescents were enrolled in this study.

Aerobic plus resistance training improves bone metabolism and inflammation in adolescents who are obese.

Obesity is a worldwide epidemic with a high prevalence of comorbidities, including alterations in bone mineral metabolism.

This was a clinical trial study with interdisciplinary weight loss therapy.

Hyperleptinemia: implications on the inflammatory state and vascular protection in obese adolescents submitted to an interdisciplinary therapy.

The low-grade systemic inflammation seen in obesity may affect the actions of some adipose tissue-derived adipokines that are involved in the regulation of vascular function. We sought to verify whether hyperleptinemia may influence the inflammatory and atherogenic responses in obese adolescents undergoing interdisciplinary therapy. Thirty-four obese adolescents underwent interdisciplinary therapy for 1 year.

Aerobic training (AT) is more effective than aerobic plus resistance training (AT+RT) to improve anorexigenic/orexigenic factors in obese adolescents.

Background: The regulation of energy balance is influenced by physical exercise. Although some studies show a stimulation of hormones related to food intake, others show that exercise provides satiety.

Aim: The aim of this study was to compare the effects of aerobic training (AT) and aerobic plus resistance training (AT+RT) on anorexigenic and orexigenic factors in obese adolescents undergoing interdisciplinary weight loss therapy.

Interaction of bone mineral density, adipokines and hormones in obese adolescents girls submitted in an interdisciplinary therapy.

Obesity is a chronic inflammatory condition with numerous metabolic consequences to the organism, highlighting its influence on bone mass. Therefore, the aim of this study was to verify the role of visceral fat, leptin, adiponectin and ghrelin on bone mineral density in obese post-puberty adolescents girls, submitted to an interdisciplinary therapy. The study involved 20 post-puberty obese adolescent girls: 16±1.

Obesity is a chronic inflammatory disease and is considered a risk factor for metabolic syndrome. In this study, 57 obese adolescents with and without metabolic syndrome underwent 1 year of weight loss therapy. At baseline, the metabolic syndrome (MS) patients presented higher values of PAI-1 than the non-metabolic syndrome patients (n-MS).

The role of pro-inflammatory and anti-inflammatory adipokines on exercise-induced bronchospasm in obese adolescents undergoing treatment.

Background: Recent studies have demonstrated a greater prevalence in exercise-induced bronchospasm (EIB) in obese adolescents. However, the role of pro-/anti-inflammatory adipokines and the repercussions of obesity treatment on EIB need to be explored further. Therefore, the objective of this study was to evaluate the role of pro-/anti-inflammatory adipokines on EIB in obese adolescents evaluated after long-term interdisciplinary therapy.
