Effect of plant sterol and galactooligosaccharides enriched beverages on oxidative stress and longevity in Caenorhabditis elegans
2020
Abstract This study evaluates the impact of two plant sterol (PS) enriched fruit beverages (0.6 g /100 ml), without (MfB) or with GOS (MfB-G) (1.2 g/100 ml) on the resistance against oxidative stress induced by non-conventional (cholesterol oxidation products (COPs)) and conventional (H2O2) oxidant compounds, as well as their impact on C. elegans longevity. Nematodes fed with both beverages (0.005–0.25%, v/v) showed similar improved oxidative stress resistance against COPs and H2O2. This effect was dependent on daf-16 transcription factor, although GOS showed an additional beneficial effect independent to daf-16. In addition, both beverages extended nematode lifespan, independently of the p…
A new class of phenylhydrazinylidene derivatives as inhibitors of Staphylococcus aureus biofilm formation
2016
In the struggle against the emergence of the antibiotic resistance, new molecules targeting biofilm formation could be useful as adjuvant of conventional antibiotics. This study focused on a new class of 2-phenylhydrazinylidene derivatives as antivirulence agents. The compound 12e showed interesting activities against biofilm formation of all tested Staphylococcus aureus strains with IC50 ranging from 1.7 to 43 µM; compounds 12f and 13a resulted strong inhibitors of S. aureus ATCC 6538 and ATCC 29213 biofilm formation with IC50 of 0.9 and 0.8 µM, respectively. A preliminary study on the mechanism of action was carried on evaluating the inhibition of sortase A transpeptidase. Compound 12e re…
Anti-Inflammatory Properties of Diet: Role in Healthy Aging
2021
Inflammation is a physiological process involved in the defenses of the body and the repair of tissues. It is acutely activated by infections, trauma, toxins, or allergic reactions. However, if it becomes chronic, inflammation can end up stimulating the development of diseases such as cardiovascular disease, autoimmune disease, neurological disease, or cancer. Additionally, during aging, inflammation becomes increasingly more chronic. Furthermore, we found that certain foods, such as saturated fats, have pro-inflammatory activity. Taking this into account, in this review we have discussed different diets with possible anti-inflammatory activity, the commonly ingested components of each diet…
Original paper: A new type of polyphenols-containing dietary supplement for correction of lipids and inflammatory markers in patients with coronary a…
2018
Abstract Objective: To evaluate the impact of two original compositions of polyphenols-containing dietary supplement on lipid profile and level of C-reactive protein (CRP) in patients with angiographycally verified coronary artery disease (CAD). Design and methods: 167 patients were selected during their scheduled post-event elective bicycle stress-test examination. All patients received standard CAD therapy and permanent statin therapy and had elevated total cholesterol (TC > 5.0 mmol/L) and/or CRP (>3.5 mg/L) levels. The study consisted of 2 days of polyphenol depletion followed by a 12-week supplementation period in a randomized, blinded, placebo-uncontrolled parallel design. Two d…
Psychometric properties of the Persian version of the nutritional form for the elderly (NUFFE) in nursing home residents
2018
Background: The Nutritional Form for the Elderly (NUFFE) is a newly developed tool. This study aimed to carry out a psychometric evaluation of the Persian version of NUFFE (NUFFE-P) among nursing home residents. Methods: Nursing home participant’s aged ≥ 60 years (n=97) were enrolled. The inclusion criteria were residency for at least 6 months in the nursing home, and ability to communicate. Exclusion criteria included cognitive impairment, having depressed mood, severe hearing loss, problems in upper and lower extremities also, history of hospital admission during 6 months before enrollment. Anthropometric measures, laboratory tests, three-day food intake, NUFFE-P version, Mini Nutritional…
Significance of magnesium in insulin resistance, metabolic syndrome, and diabetes – recommendations of the Association of Magnesium Research e.V.
2017
Magnesium (Mg) depletion is an important and highly prevalent condition in patients with diabetes or precursor states of type-2 diabetes like metabolic syndrome. Mg deficiency increases the risk of developing type-2 diabetes. These recommendations compile present data on the physiology of Mg in carbohydrate metabolism and pathophysiological consequences of Mg depletion for diabetics. Diabetes patients and candidates benefit from four categories of Mg effects: insulin-sensitizing effect, calcium antagonism, stress-regulating and endotheli-um-stabilizing effects. Clinical data with Mg co-medication show improvement of insulin resistance/blood glucose level and reduced long-term vascular damag…
Serum vitamin D and functional impairment in octogenarian women.
2016
Abstract Purpose Serum vitamin D deficiency has been associated with frailty in people aged 65 and over, however its relationship with functional impairment has not been investigated in octogenerian (aged 80–90 years) institutionalized women. Methods We assessed functional impairment in this latter group by measuring frailty syndrome and other geriatric and psychological assessment scales: the Tinetti gait and balance index to determine the risk for falls, the Barthel index to measure the basic activities of daily living, the Lawton index for instrumental activities, the mini-mental score examination test for cognitive impairment, the Yesavage scale for geriatric depression, and the Norton …
Coffee and metabolic impairment: An updated review of epidemiological studies
2016
Abstract Background Coffee is one of the most consumed beverages worldwide. In the last years, coffee consumption has been associated with a number of beneficial effects against metabolic impairment. The aim of this narrative review was to report the most updated and comprehensive evidence from epidemiological and experimental studies as well as mechanisms of action of coffee on metabolic impairment. Methods A search in electronic databases (PUBMED and EMBASE) was performed to retrieve systematic and pooled analyses on coffee and diabetes, hypertension, and dyslipidemia. Furthermore, the most accredited hypotheses and mechanisms of action of coffee have been described. Results Coffee consum…
The diversity of healthy diets for older persons across the world.
2018
Purpose of review To examine eating patterns, and with a particular focus on the different healthy diets followed by older persons across the world and the factors that can limit accessibility to healthy foods. Recent findings Recent evidence has demonstrated that older people are, generally speaking, following less healthy diets with respect to the past. The only exception seems to be China, but the quality of the food there appears to be less than optimal. Socioeconomic status and, in particular, the price of food seems to be the most important factors linked to diet quality. Summary Although healthy diets are associated with lower risk of several chronic disabling diseases, elderly peopl…
Factors influencing serum 25-hydroxivitamin D levels and other bone metabolism parameters in healthy older women
2016
Objective: Older women have frequently low serum 25-hydroxivitamin D (25[OH]D) concentrations, high parathormone (PTH) levels and low bone mineral density (BMD) values. Endogenous synthesis, dietary habits, sunlight exposure and fat-mass-mediated storage may influence 25(OH)D levels and bone metabolism, but the relevance of these factors in the elderly has yet to be fully elucidated. We aimed to investigate the influence of dietary vitamin D intake and fat mass on serum 25(OH)D levels and bone metabolism in older women. Design: Cross-sectional. Setting: Community. Participants: 218 fit older women attending a biweekly mild fitness program. Measurements: Dietary habits was investigated throu…
