Pro-inflammatory genetic background and zinc status in old atherosclerotic subjects.

2008

Inflammation and genetics are prominent mechanisms in the pathogenesis of atherosclerosis (AT) and its complications. In this review we discuss the possible impact on AT development of several genetic determinants involved in inflammation, oxidative stress and cytoprotection (IL-6, TNF-alpha, IL-10, CD14, TLR4, MT, HSP70). Genetic polymorphisms of these genes may affect a differential inflammatory response predisposing to AT. However, allelic polymorphisms of genes which increase the risk of AT frequently occur in the general population but, only adequate gene-environment-polymorphism interactions promote the onset of the disease. Zinc deficiency has been suggested as an environmental risk …

Magnesium in Aging, Health and Diseases

2021

Several changes of magnesium (Mg) metabolism have been reported with aging, including diminished Mg intake, impaired intestinal Mg absorption and renal Mg wasting. Mild Mg deficits are generally asymptomatic and clinical signs are usually non-specific or absent. Asthenia, sleep disorders, hyperemotionality, and cognitive disorders are common in the elderly with mild Mg deficit, and may be often confused with age-related symptoms. Chronic Mg deficits increase the production of free radicals which have been implicated in the development of several chronic age-related disorders. Numerous human diseases have been associated with Mg deficits, including cardiovascular diseases, hypertension and s…

Does the association of therapeutic exercise and supplementation with sucrosomial magnesium improve posture and balance and prevent the risk of new f…

2021

Abstract Background Fracture of the proximal femur is the most feared complication of osteoporosis. Given the numerous physiological functions that magnesium performs in our body, in the literature there is a correlation between osteoporosis and low serum levels of magnesium. Aim Evaluate the incidence of hypomagnesemia in patients with lateral fragility fracture of the proximal femur, the possible correlation between serum magnesium levels and fractures, and the effectiveness of supplementing Sucrosomial® magnesium associated with therapeutic exercise on the outcome of these patients. Methods We divided the study into two parts. In the first part, we assessed the preoperative incidence of …

Effects of Nrf2 deficiency on bone microarchitecture in an experimental model of osteoporosis

2014

Objective. Redox imbalance contributes to bone fragility. We have evaluated the in vivo role of nuclear factor erythroid derived 2-related factor-2 (Nrf2), an important regulator of cellular responses to oxidative stress, in bone metabolism using a model of postmenopausal osteoporosis. Methods. Ovariectomy was performed in both wild-type and mice deficient in Nrf2 (Nrf2-/-). Bone microarchitecture was analyzed by CT. Serum markers of bone metabolism were also measured. Reactive oxygen species production was determined using dihydrorhodamine 123. Results. Sham-operated or ovariectomized Nrf2 -/- mice exhibit a loss in trabecular bone mineral density in femur, accompanied by a reduction in co…

Inflammation, genes and zinc in ageing and age-related diseases.

2006

Lifelong antigenic burden determines a condition of chronic inflammation, with increased lymphocyte activation and pro-inflammatory cytokine production. A large number of studies have documented changes in Zn metabolism in experimental animal models of acute and chronic inflammation and in human chronic inflammatory diseases. In particular, modification of zinc plasma concentration as well as intracellular disturbance of antioxidant intracellular pathways have been found associated to age-related inflammatory diseases, like atherosclerosis. Zinc deficiency is extremely diffused in aged people that are educated to avoid meat and other high Zn-content foods due to fear of cholesterol. Rather,…

Anaphylaktischer Schock nach Lipid-Austauschchromatographie bei einer Patientin mit angeborenem IgA-Mangel

1995

We report on a 59-year-old woman patient with selective IgA deficiency and familial hypercholesterinaemia. To lower elevated LDL levels in the patient's blood, immunoadsorption therapy with sheep-anti-human polyclonal antibodies coupled to sepharose columns was administered. During the procedure, the patient developed an anaphylactic shock requiring intensive care treatment. The patient's history revealed a fresh cell therapy with fetal sheep cells 10 years previously. Intracutaneous testing confirmed sensitization to sheep immunoglobulin, which was the most likely reason for the anaphylactic shock.

Telomere attrition in peripheral blood mononuclear cells of children with alpha-1 antitrypsin deficiency

2015

Background: Our research group have demonstrated that oxidative stress (OS) is involved in the pathophysiology of alpha-1 antitrypsin deficiency (AATD) (Escribano A. et al. Thorax 2015;70:82-3). In addition, many evidences have shown that OS accelerates telomere shortening in several lung pathologies. Short telomeres have been associated to higher emphysema risk in COPD patients. Rationale: Since AATD is characterised by chronic OS, we hypothesise that telomere shortening would be accelerated in AATD patients and would be associated with higher risk of developing lung disease. Aims: To assess telomere length (TL) in AATD patients and to study its association with AAT phenotypes. Methods: TL…

Metabolic impact of adult-onset, isolated, growth hormone deficiency (AOiGHD) due to destruction of pituitary somatotropes.

2011

Growth hormone (GH) inhibits fat accumulation and promotes protein accretion, therefore the fall in GH observed with weight gain and normal aging may contribute to metabolic dysfunction. To directly test this hypothesis a novel mouse model of adult onset-isolated GH deficiency (AOiGHD) was generated by cross breeding rat GH promoter-driven Cre recombinase mice (Cre) with inducible diphtheria toxin receptor mice (iDTR) and treating adult Cre(+/-), iDTR(+/-) offspring with DT to selectively destroy the somatotrope population of the anterior pituitary gland, leading to a reduction in circulating GH and IGF-I levels. DT-treated Cre(-/-), iDTR(+/-) mice were used as GH-intact controls. AOiGHD im…
