Spheroids from adipose-derived stem cells exhibit an miRNA profile of highly undifferentiated cells
2017
Two-dimensional (2D) cell cultures have been extensively used to investigate stem cell biology, but new insights show that the 2D model may not properly represent the potential of the tissue of origin. Conversely, three-dimensional cultures exhibit protein expression patterns and intercellular junctions that are more representative of their in vivo condition. Multiclonal cells that grow in suspension are defined as "spheroids," and we have previously demonstrated that spheroids from adipose-derived stem cells (S-ASCs) displayed enhanced regenerative capability. With the current study, we further characterized S-ASCs to further understand the molecular mechanisms underlying their stemness pr…
γδ cell-based immunotherapy for cancer.
2019
Introduction: Cancer immunotherapy relies on the development of an efficient and long-lasting anti-tumor response, generally mediated by cytotoxic T cells. gamma delta T cells possess distinctive features that justify their use in cancer immunotherapy. Areas covered: Here we will review our current knowledge on the functions of human gamma delta T cells that may be relevant in tumor immunity and the most recent advances in our understanding of how these functions are regulated in the tumor microenvironment. We will also discuss the major achievements and limitations of gamma delta T cell-based immunotherapy of cancer. Expert opinion: Several small-scale clinical trials have been conducted i…
Evaluation of serum CA 125 levels in patients with pelvic pain related to endometriosis.
2007
The aim of the study was to investigate the clinical value of the serum CA 125 level for diagnosing and determining the severity of endometriosis and pelvic pain associated with endometriosis. Eighty-six women who underwent operative laparoscopy were enrolled. Sixty-nine women with endometriosis and 17 without endometriosis participated in this study. In all of the patients, endometriosis was diagnosed and classified into stages according to the Revised American Fertility Society (R-AFS) classification. The mean serum CA 125 levels were determined in each patient. We also investigated the relationship between serum CA 125 concentration and the intensity of dysmenorrhea and dyspareunia in t…
Systemic redox biomarkers and their relationship to prognostic risk markers in autosomal dominant polycystic kidney disease and IgA nephropathy.
2017
Abstract Background Oxidative stress is evident from an early stage in chronic kidney disease (CKD). Therefore, we investigated redox biomarkers in polycystic kidney disease (ADPKD) and IgA nephropathy (IGAN). Methods This is a case-control study with three groups: ADPKD (n = 54), IGAN (n = 58) and healthy controls (n = 86). The major plasma aminothiols with their redox species were examined: homocysteine (Hcy), cysteinglycine (CG), cysteine (Cys) and glutathione (GSH). The redox ratio was the ratio of reduced free and oxidized aminothiols in plasma. We investigated malonedialdehyde (MDA) and advanced oxidation protein products (AOPP), and ten single nucleotide polymorphisms of antioxidant …
Resting Energy Expenditure and Substrate Oxidation in Malnourished Patients With Type 1 Glycogenosis.
2019
Abstract Context Type 1a and 1b glycogenosis [glycogen storage disorder (GSD)1a, GSD1b] are rare diseases generally associated with malnutrition. Although abnormal substrate oxidation rates and elevated energy expenditures might contribute to malnutrition, this issue has not been investigated. Objective To investigate whether abnormal resting energy expenditure (REE) and substrate oxidation rate characterize patients with GSD1. Design Cross-sectional study Setting Outpatient referral center for rare diseases and laboratory of clinical nutrition at the University Hospital of Palermo Patients Five consecutive patients with GSD1 (4 type a, 1 type b; 3 men, 2 women; age range, 19 to 49 years) M…
Sex Alters the MHC Class I HLA-A Association With Polyglandular Autoimmunity.
2018
Abstract Context The major histocompatibility complex (MHC) strongly contributes to the development of polyglandular autoimmunity (PGA). Objective To evaluate the impact of sex on human leukocyte antigen (HLA) association with PGA for the first time. Design Cross-sectional immunogenetic study. Setting Academic tertiary referral Orphan Disease Center for PGA (ORPHA 282196) and immunogenetics laboratory. Subjects Patients (158) with coexistent type 1 diabetes and autoimmune thyroid disease (adult type 3 PGA, ORPHA 227982) and 479 unrelated healthy controls. Interventions All 637 white subjects were typed for HLA-A, -B, -DRB1, -DQA1, and -DQB1 alleles at a two-field level. Main Outcome Measure…
Liver Fat Content in People with Pituitary Diseases: Influence of Serum IGF1 Levels
2017
AbstractNon-alcoholic fatty liver disease (NAFLD) is commonly associated with obesity, metabolic syndrome, and type 2 diabetes. NAFLD is also seen in patients with endocrinopathies. However, the relationship between endocrine diseases and the development of NAFLD is not well known. In this study, we set out to determine whether liver fat content (LFC) was associated with IGF1 levels in people with pituitary diseases (PD). Eighty-nine patients with pituitary diseases and 74 healthy controls were included in this study. LFC was measured using MRI. Hepatic steatosis was defined as LFC>5.5%. Patients with PD were older, and had a higher BMI than healthy controls. LFC was significantly higher…
Obesity impairs leukocyte‐endothelium cell interactions and oxidative stress in humans
2018
Background:To evaluate the relationship between leukocyte‐endothelial cellinteractions and oxidative stress parameters in non‐diabetic patients with differentgrades of obesity.Material and methods:For this cross‐sectional study, 225 subjects wererecruited from January 1, 2014 to December 31, 2016 and divided into groupsaccording to BMI (40 kg/m²). We determined clin-ical parameters, systemic inflammatory markers, soluble cellular adhesion mole-cules, leukocyte‐endothelium cell interactions—rolling flux, velocity and adhesion—, oxidative stress parameters—total ROS, total superoxide, glutathione—andmitochondrial membrane potential in leukocytes.Results:We verified that HOMA‐IR and hsCRP incr…
