In Vitro Antioxidant Activity and In Vivo Topical Efficacy of Lipid Nanoparticles Co-Loading Idebenone and Tocopheryl Acetate
2019
Idebenone (IDE) is a strong antioxidant that has been proposed for the treatment of skin disorders, including skin ageing. Unfavorable physico-chemical properties make IDE a poor skin permeant where effectiveness could be improved by its loading into suitable delivery systems such as solid lipid nanoparticles (SLN) and nanostructured lipid carriers (NLC). In this work, we designed novel IDE-loaded NLC containing tocopheryl acetate (VitE) as a liquid component to obtain a synergic effect between IDE and VitE. The resulting NLC showed small particle sizes (24&ndash
Mycorrhizal symbiosis changes host nitrogen source use
2021
Abstract Purpose The ecological importance of arbuscular mycorrhizal fungi (AMF) in plant acquisition of inorganic and organic sources of nitrogen (N) is not clear. To improve understanding of the plant N nutrition ecology, we tested the effect of intraspecific competition and AMF in plant N source use in growth and N acquisition. Methods Solidago virgaurea was grown in microcosms in a fully factorial experiment under greenhouse conditions. The factors tested were intraspecific competition between seedlings and adult plants (yes, no), N source (NH4, glycine) and AMF (inoculated with Glomus hoi, not inoculated). Results When grown separately, non-mycorrhizal seedling growth was highest when …

Looking for the best immune-checkpoint inhibitor in pre-treated NSCLC patients: An indirect comparison between nivolumab, pembrolizumab and atezolizu…
2017
Immune-checkpoint inhibitors represent the new standard of care in patients with advanced NSCLC who progressed after first-line treatment. This work aim to assess any difference in both efficacy and safety profiles among Nivolumab, Pembrolizumab and Atezolizumab in pre-treated NSCLC patients. Randomized clinical trials comparing immune-checkpoint inhibitor versus docetaxel in pre-treated patients with advanced NSCLC were included and direct comparison meta-analysis of selected trials have been performed. Subsequently the summary estimates of Nivolumab, Pembrolizumab and Atezolizumab emerging from the direct meta-analysis were selected to provide the pooled estimates of hazard ratio (HR) and…
Comparing tacrolimus ointment and oral cyclosporine in adult patients affected by atopic dermatitis: a randomized study
2004
BACKGROUND: Atopic dermatitis (AD) is a chronic allergic inflammatory disease, which manifests itself with eczematous skin lesions. OBJECTIVE: We compared the clinical efficacy of tacrolimus ointment (0.1%) given twice a day and oral cyclosporine (3 mg/kg) given once daily. Rescue medication for itching included cetirizine 10-20 mg (equal to one or two tables). METHODS: Thirty patients, aged 13-45 years (mean+/-SD 27.1+/-10.9), with a history of moderate-to-severe AD were randomized to treatments, 15 patients for each treatments. Assessment of efficacy was based on SCORAD, on scores of daily itching, erythema, interference with sleep, due to the skin condition and days without use of cetiri…
Probiotics in the prevention and treatment of atopic dermatitis
2020
The use of probiotic supplements might change the composition of the intestinal flora of children, subsequently modulating the immune system's reactivity. The effects of probiotic administration for the prevention/treatment of allergic diseases and atopic dermatitis, in particular, are still so controversial that no definitive recommendation can be made at this stage. Differences in strain specificity, timing, and length of administration all contribute to diversifying the conclusions of this review.
Probiotiku izvēle atopiskā dermatīta gadījumos
2018
Alerģijas epidēmijas veicināšanā lielu lomu spēlē mūsdienu attīstītās sabiedrības dzīvesveids, kuru raksturo mikrobiālas floras nomākšana, tā izmainot cilvēka mikrobiotu un negatīvi ietekmējot imūno regulāciju (Fiocchi et al 2015). Maģistra darba mērķis bija noskaidrot dermatologu viedokli par atopisko dermatītu, ņemot vērā ārstēšanas vadlīnijas, un, izanalizējot zinātniskās publikācijas, izpētīt atopiskā dermatīta ārstēšanas tendences Latvijā, un izpētīt probiotiķu lomu atopiskā dermatīta profilaksē. Anketas aizpildīja ārsti – dermatologi (praktizējošie ārsti). Datu analīzei tika izmantotas 70 aptaujas. Secinājumi: Atopiskā dermatīta ārstēšanā visbiežāk izvēlas topiski lietojamos glokokort…
Bempedoic acid as adjunct for traditional lipid-lowering therapy in patients with hyperlipidaemia
2020
Statin therapy has been the cornerstone for the reduction of cholesterol and circulating low-density lipoprotein (LDL) in patients with cardiovascular diseases. However, statin monotherapy has disadvantages attributable to myopathies and to the insufficient cholesterol reduction observed in some patients. There is a need for new well-tolerated therapies for lowering LDL. This review will focus on bempedoic acid in combination with traditional statin therapy or other lipid-lowering agents and its emerging role in LDL-C lowering. Bempedoic acid is also a viable alternative for reducing LDL cholesterol in the treatment of some patients suffering from heterozygous familial hypercholesterolemia.
Role of GATA-1 and HSP70 in the Dyserythropoiesis of Early Myelodysplastic Syndromes.
2009
Abstract Abstract 3823 Poster Board III-759 Myelodysplastic syndromes (MDS) are heterogeneous hematopoietic stem cell disorders characterized by a hypercellular dysplastic bone marrow (BM) with peripheral blood cytopenias, mainly anemia. Early MDS with less than 10% BM blasts which belong in most cases to low and intermediate-1 (int-1) risk groups according to the International Prognostic Scoring System (IPSS), usually demonstrate dyserythropoiesis. The growth of erythroid progenitors is altered, with increased caspase activation leading to excessive cell death, and cellular dysplasia characterized, in liquid culture of CD34+-derived erythroid progenitors, by a delayed expression of the gly…
