H-ferritin and proinflammatory cytokines are increased in the bone marrow of patients affected by macrophage activation syndrome
2017
Summary Macrophage activation syndrome (MAS) is hyperinflammatory life-threatening syndrome, associated typically with high levels of serum ferritin. This is an iron storage protein including heavy (H) and light (L) subunits, categorized on their molecular weight. The H-/L subunits ratio may be different in tissues, depending on the specific tissue and pathophysiological status. In this study, we analysed the bone marrow (BM) biopsies of adult MAS patients to assess the presence of: (i) H-ferritin and L-ferritin; (ii) CD68+/H-ferritin+ and CD68+/L-ferritin+; and (iii) interleukin (IL)-1β, tumour necrosis factor (TNF) and interferon (IFN)-γ. We also explored possible correlations of these re…
Curcumin as a therapeutic option in retinal diseases
2020
Este artículo se encuentra disponible en la siguiente URL: https://www.mdpi.com/2076-3921/9/1/48 Este artículo pertenece al número especial "Natural products in health promotion and disease prevention". En este artículo también participa: Vincent M. Villar. The retina is subjected to oxidative stress due to its high vascularization, long time light exposition and a high density of mitochondria. Oxidative stress can lead to pathological processes, like cell apoptosis, angiogenesis and inflammation ending in retinal pathologies. Curcumin, a major bioactive component obtained from the spice turmeric (Curcuma longa) rhizome has been used for centuries in Asian countries for cooking and for curi…
Study of nucleation status in the second cell cycle of human embryo and its impact on implantation rate
2016
Objective To study nucleation status in two- and four-cell embryos and its effect on reproductive outcomes. Design Retrospective cohort study. Setting University-affiliated private center. Patient(s) A total of 1,679 embryos from 940 oocyte donation cycles from May 2012 to May 2014. Intervention(s) None. Main Outcome Measure(s) Implantation, morphokinetics, and nucleation status restoration. Result(s) Multinucleation was present in 42.53% of embryos with known implantation data at the two-cell stage; it was present in approximately 14% of them at the four-cell stage. In all, 73.4% of the embryos were multinucleated at two cells and restored their nucleation status when they cleaved into fou…
Application of enamel matrix derivative in conjunction with non‐surgical therapy for treatment of moderate to severe periodontitis: A 12‐month, rando…
2020
BACKGROUND Treatment of periodontitis aims to halt progressive bone and attachment loss and regenerate periodontal structures. In this study, the effect of using an enamel matrix derivative (EMD) as an adjunct to non-surgical periodontal therapy (test) versus non-surgical therapy alone (control) was evaluated. METHODS A prospective, split-mouth, multicenter study evaluated scaling and root planing (SRP) with and without EMD in 51 patients presenting with moderate to severe periodontitis (PPD = 5 to 8 mm) in at least 2 pockets per contralateral quadrants within the same arch. The primary outcome variable was change in clinical attachment level (CAL) after 12 months. Secondary variables inclu…
Serum Amino Acid Profiles in Childhood Predict Triglyceride Level in Adulthood: A 7-Year Longitudinal Study in Girls.
2016
AbstractContext:Branched-chain and aromatic amino acids are associated with high risk of developing dyslipidemia and type II diabetes in adults.Objective:This study aimed to examine whether serum amino acid profiles associate with triglyceride concentrations during pubertal growth and predict hypertriglyceridemia in early adulthood.Design:This was a 7.5-year longitudinal study.Setting:The study was conducted at the Health Science Laboratory, University of Jyväskylä.Participants:A total of 396 nondiabetic Finnish girls aged 11.2 ± 0.8 years at the baseline participated in the study.Main Outcome Measures:Body composition was assessed by dual-energy x-ray absorptiometry; serum concentrations o…
Unsaturated Oral Fat Load Test Improves Glycemia, Insulinemia and Oxidative Stress Status in Nondiabetic Subjects with Abdominal Obesity.
2016
Aims To evaluate the changes in glycemia, insulinemia, and oxidative stress markers during an oral fat load test in nondiabetic subjects with abdominal obesity and to analyze the association between postprandial oxidative stress markers and postprandial glucose and insulin responses. Methods We included 20 subjects with abdominal obesity (waist circumference > 102 cm for men and > 88 cm for women) and 20 healthy lean controls (waist circumference < 102 cm for men and < 88 cm for women). After 12 hours of fasting we performed a standardized fat load test (0–8 hours) with supracal® (50 g/m2). We determined metabolic parameters, oxidized and reduced glutathione, and malondialdehyde. Results In…
Amorphous, Smart, and Bioinspired Polyphosphate Nano/Microparticles: A Biomaterial for Regeneration and Repair of Osteo-Articular Impairments In-Situ
2018
Using femur explants from mice as an in vitro model, we investigated the effect of the physiological polymer, inorganic polyphosphate (polyP), on differentiation of the cells of the bone marrow in their natural microenvironment into the osteogenic and chondrogenic lineages. In the form of amorphous Ca-polyP nano/microparticles, polyP retains its function to act as both an intra- and extracellular metabolic fuel and a stimulus eliciting morphogenetic signals. The method for synthesis of the nano/microparticles with the polyanionic polyP also allowed the fabrication of hybrid particles with the bisphosphonate zoledronic acid, a drug used in therapy of bone metastases in cancer patients. The r…
Novel molecular mechanisms for the adaptogenic effects of herbal extracts on isolated brain cells using systems biology.
2018
Abstract Introduction Adaptogens are natural compounds or plant extracts that increase adaptability and survival of organisms under stress. Adaptogens stimulate cellular and organismal defense systems by activating intracellular and extracellular signaling pathways and expression of stress-activated proteins and neuropeptides. The effects adaptogens on mediators of adaptive stress response and longevity signaling pathways have been reported, but their stress-protective mechanisms are still not fully understood. Aim of the study The aim of this study was to identify key molecular mechanisms of adaptogenic plants traditionally used to treat stress and aging-related disorders, i.e., Rhodiola r…
The role of tumor-associated macrophages in gastric cancer development and their potential as a therapeutic target.
2020
Gastric cancer (GC) represents the fifth cause of cancer-related death worldwide. Molecular biology has become a central area of research in GC and there are currently at least three major classifications available to elucidate the mechanisms that drive GC oncogenesis. Further, tumor microenvironment seems to play a crucial role, and tumor-associated macrophages (TAMs) are emerging as key players in GC development. TAMs are cells derived from circulating chemokine- receptor-type 2 (CCR2) inflammatory monocytes in blood and can be divided into two main types, M1 and M2 TAMs. M2 TAMs play an important role in tumor progression, promoting a pro-angiogenic and immunosuppressive signal in the tu…
Influence of different types of pulp treatment during isolation in the obtention of human dental pulp stem cells
2016
Background: Different methods have been used in order to isolate dental pulp stem cells. The aim of this study was to study the effect of different types of pulp treatment during isolation, under 3% O 2 conditions, in the time needed and the efficacy for obtaining dental pulp stem cells. Material and Methods: One hundred and twenty dental pulps were used to isolate dental pulp stem cells treating the pulp tissue during isolation using 9 different methods, using digestive, disgregation, or mechanical agents, or combining them. The cells were positive for CD133, Oct4, Nestin, Stro-1, CD34 markers, and negative for the hematopoietic cell marker CD-45, thus confirming the presence of mesenchyma…
