Prevalence of Age-Related Macular Degeneration in Europe
2017
Manuscript no. 2016-1147 Supplemental material is available at www.aaojournal.org/; International audience; [u]Purpose:[/u] Age-related macular degeneration (AMD) is a frequent, complex disorder in elderly of European ancestry. Risk profiles and treatment options have changed considerably over the years, which may have affected disease prevalence and outcome. We determined the prevalence of early and late AMD in Europe from 1990 to 2013 using the European Eye Epidemiology (E3) consortium, and made projections for the future. [u]Design:[/u] Meta-analysis of prevalence data. [u]Participants:[/u] A total of 42 080 individuals 40 years of age and older participating in 14 population-based cohor…
Safety of red yeast rice supplementation: A systematic review and meta-analysis of randomized controlled trials.
2019
International audience; Recently, concerns regarding the safety of red yeast rice (RYR) have been raised after the publication of some case reports claiming toxicity. Since the previous meta-analyses on the effects of RYR were mainly focused on its efficacy to improve lipid profile and other cardiovascular parameters, we carried out a meta-analysis on safety data derived from the available randomized controlled clinical trials (RCTs). Primary outcomes were musculoskeletal disorders (MuD). Secondary outcomes were non-musculoskeletal adverse events (Non-MuD) and serious adverse events (SAE). Subgroups analyses were carried out considering the intervention (RYR alone or in association with oth…
Lipoproteins LDL versus HDL as nanocarriers to target either cancer cells or macrophages
2020
free open access article 31 p.; International audience; In this work, we have explored natural unmodified low- and high-density lipoproteins (LDL and HDL) as selective delivery vectors in colorectal cancer therapy. We show in vitro in cultured cells and in vivo (NanoSPECT/CT) in the CT-26 mice colorectal cancer model that LDLs are mainly taken up by cancer cells, while HDLs are preferentially taken up by macrophages. We loaded LDLs with cisplatin and HDLs with the heat shock protein-70 inhibitor AC1LINNC, turning them into a pair of “Trojan horses” delivering drugs selectively to their target cells as demonstrated in vitro in human colorectal cancer cells and macrophages, and in vivo. Coupl…
Analysis of Lipid Peroxidation by UPLC-MS/MS and Retinoprotective Effects of the Natural Polyphenol Pterostilbene
2021
The loss of redox homeostasis induced by hyperglycemia is an early sign and key factor in the development of diabetic retinopathy. Due to the high level of long-chain polyunsaturated fatty acids, diabetic retina is highly susceptible to lipid peroxidation, source of pathophysiological alterations in diabetic retinopathy. Previous studies have shown that pterostilbene, a natural antioxidant polyphenol, is an effective therapy against diabetic retinopathy development, although its protective effects on lipid peroxidation are not well known. Plasma, urine and retinas from diabetic rabbits, control and diabetic rabbits treated daily with pterostilbene were analyzed. Lipid peroxidation was evalu…
Oxidation-Induced Increase In Photoreactivity of Bovine Retinal Lipid Extract
2017
Open access original paper Source : 10th EPR Workshop on Applications of EPR in Biology and Medicine, 2016 in Krakow, POLAND.; International audience; The mammalian retina contains a high level of polyunsaturated fatty acids, including docosahexaenoic acid (22:6) (DHA), which are highly susceptible to oxidation. It has been shown that one of the products of DHA oxidation-carboxyethylpyrrole (CEP), generated in situ, causes modifications of retinal proteins and induces inflammation response in the outer retina. These contributing factors may play a role in the development of age-related macular degeneration (AMD). It is also possible that some of the lipid oxidation products are photoreactiv…

Local complications associated with labial salivary gland biopsy for diagnosis of Sjögren?s Syndrome : a retrospective cohort study
2019
Background To describe local or systemic complications related to the labial salivary glands biopsy (LSGB) used as diagnostic tool for the diagnosis of Sjogren's Syndrome (SS). Material and methods Clinical databases from a cohort of patients, who underwent LSGB with provisional clinical diagnosis of Sjogren's Syndrome, were retrospectively reviewed. Pain, assessed by registering the intake of analgesic drugs in the first week following the biopsy, and any further relevant clinical information regarding complications after biopsy were recorded. Results 50 patients received LSGB. 10 of them (9 women and 1 man) showed histopathological findings compatible with SS. Ten patient (20%) receiving …
Multidisciplinary oral rehabilitation in partially edentulous adult patients with malocclusion: a cross-sectional survey study
2018
Background A cross-sectional survey was conducted to gather information regarding the opinion of Brazilian specialists in both orthodontics and implantology on multidisciplinary oral rehabilitation in partially edentulous patients with malocclusion. Material and methods A total of 305 specialists participated in a telephone survey and answered an ad hoc 10-item questionnaire, including the request of total skull cone-beam tomographies (CBCT) and the use of 3D digital planning software, the best moment of treatment to place dental implants, and the integration of orthodontics in implantology. Results Most participants did not request CBCT (90.8%) or 3D digital planning software images (92.3%…
