Oxidant mechanisms in childhood obesity: the link between inflammation and oxidative stress.
2011
Evidence of obesity-induced oxidative stress in adults has emerged in the past several years, and similar evidence has been demonstrated in children more recently. The reactive species of oxygen or nitrogen can chemically alter all major classes of biomolecules by modifying their structure and function. Organisms have developed mechanisms to protect biomolecules from the deleterious effects of free radicals. These include the enzymes superoxide dismutase, catalase, and glutathione peroxidase, as well as water and lipid-soluble antioxidants, such as glutathione, ascorbate (vitamin C), α-tocopherol (vitamin E), and β-carotene. Obesity creates oxidant conditions that favor the development of c…
Social frailty increases the risk of all-cause mortality: A longitudinal analysis of the English Longitudinal Study of Ageing
2022
Objectives\ud Social frailty is a common condition in older people, but its consequences are largely unknown. Therefore, in this longitudinal analysis, we aimed to investigate the association between social frailty and risk of all-cause mortality in a large sample of older people.\ud Design\ud Longitudinal, cohort.\ud Settings and participants\ud Older people participating to the English Longitudinal Study of Ageing (ELSA).\ud Methods\ud Social frailty was defined based on financial difficulty, household status, social activity, and contacts with other people: social frailty was defined as ≥2 points, social pre-frailty (1 point), and robustness (0 points). Survival status during ten years o…
Reduced In Vivo Aortic Uptake of Radiolabeled Oxidation-Specific Antibodies Reflects Changes in Plaque Composition Consistent With Plaque Stabilizati…
2004
Objective— Labeled oxidation-specific antibodies (Ox-AB) detect, quantify, and noninvasively image lipid-rich atherosclerotic lesions. However, it is unknown whether Ox-AB detect plaque stabilization. Methods and Results— The aortic uptake of intravenously injected 125 I-MDA2 (Ox-AB to malondialdehyde [MDA]–low-density lipoprotein [LDL]) was quantitated in: (1) LDL receptor−/− mice with established atherosclerosis continued on Western diet (Progression) or switched to chow (Regression) or chow+vitamins E and C (Regression-VIT) for 6 months; and (2) Watanabe rabbits (3- to 57-months old) with naturally evolved atherosclerotic lesions. In mice, the Progression group had more extensive athero…
Enhancement of the FGFR1 signaling in the FGFR1-5-HT1A heteroreceptor complex in midbrain raphe 5-HT neuron systems. Relevance for neuroplasticity an…
2015
New findings show existence of FGFR1-5-HT1A heteroreceptor complexes in 5-HT nerve cells of the dorsal and median raphe nuclei of the rat midbrain and hippocampus. Synergistic receptor-receptor interactions in these receptor complexes indicated their enhancing role in hippocampal plasticity. The existence of FGFR1-5-HT1A heteroreceptor complexes also in midbrain raphe 5-HT nerve cells open up the possibility that antidepressant drugs by increasing extracellular 5-HT levels can cause an activation of the FGF-2/FGFR1 mechanism in these nerve cells as well. Therefore, the agonist modulation of the FGFR1-5-HT1A heteroreceptor complexes and their specific role is now determined in rat medullary …

Lo bueno, si breve, dos veces bueno a veces
2007
Los bebedores pueden distribuirse dentro de un continuum, de acuerdo con su nivel de riesgo y problemas. Las intervenciones deberían distribuirse y administrarse también sin solución de continuidad, incluyendo desde la prevención hasta la rehabilitación.La intervención breve es una de las mejores estrategias para reducir la carga morbosa del alcohol; por otra parte, los pacientes dependientes deberían ser tratados con intervenciones amplias y personalizadas con años de seguimiento. Breve y extenso al mismo tiempo, ¿es una contradicción?Se presenta una reflexión en torno a la ampliación de la base del tratamiento y la necesidad de identificar las dimensiones psíquica , física y social dentro…

Inhibitory effects of N-acetylcysteine on superoxide anion generation in human polymorphonuclear leukocytes.
1997
Abstract It has been suggested that reactive oxygen species released by activated polymorphonuclear leukocytes (PMN) in man is one mechanism of tissue injury. Therapeutic action aimed at increasing antioxidant defence mechanisms is still a clinical challenge. This study examines the activity of N-acetylcysteine, a known antioxidant, in the protection of PMN exposed in-vitro to the chemoattractant peptide fMet-Leu-Phe (FMLP), the protein kinase C activator phorbol myristate acetate or the lipid peroxidation promoter t-butyl hydroperoxide. FMLP (3–300 nm) and phorbol myristate acetate (160 pm–160 nm) induced concentration-related superoxide anion generation. Pre-treatment with N-acetylcystein…
