Inflammation et immunité : implications dans l’obésité et le diabète de type 2
2006
The evidences have been increasingly accumulated on the implication of inflammatory mediators like tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in the pathological states related to insulin resistance like obesity, type 2 diabetes and atherosclerosis. There seems a link between insulin resistance and these pro-inflammatory agents, secreted by macrophages and adipocytes. Th (helper) cells are differentiated into either Th1 or Th2 phenotypes. It is generally considered that Th1 phenotype is pro-inflammatory whereas Th2 phenotype exerts anti-inflammatory (protective) effects. The upregulation of Th1 phenotype may aggravate these pathologies. One of the adipokines, i.e., adiponectin…
Magnetic Resonance Imaging Derived Biomarkers of IDH Mutation Status and Overall Survival in Grade III Astrocytomas
2020
The evaluation of the isocitrate dehydrogenase (IDH) mutation status in the glioma decision-making process has diagnostic, prognostic and therapeutic implications. The aim of this study was to evaluate whether conventional magnetic resonance imaging (MRI) and apparent diffusion coefficient (ADC) can noninvasively predict the most common IDH mutational status (R132H) in GIII-astrocytomas and the overall survival (OS). Hence, twenty-two patients (9-F, 13-M) with a histological diagnosis of GIII-astrocytoma and evaluation of IDH-mutation status (12-wild type, 10-mutant) were retrospectively evaluated. Imaging studies were reviewed for the morphological feature and mean ADC values (ADCm). Stati…

Are biological drugs effective and safe in older severe asthmatics?
2019
Introduction: The treatment of asthma in older ages follows the recommendations of international guidelines for the management of asthma in younger ages, although older age has always represented an exclusion criterion for eligibility to pharmacological trials. This poses a clinical challenge when deciding whether elderly severe asthmatics are candidates for biological drugs. Areas covered: The current article has a narrative structure to review the current literature on efficacy and safety of novel pharmacological drugs against immunoglobulins and interleukins that mediate and orchestrate the main inflammatory pathways in severe asthma, in order to explore whether older subjects (i.e. >…
A Real-World Study of Dexamethasone Implant in Treatment-Naïve Patients with Diabetic Macular Edema: Efficacy and Correlation Between Inflammatory Bi…
2020
Purpose There has been an increasing clinical interest in specific retinal parameters as non-invasive biomarkers of retinal inflammation in diabetic macular edema (DME) that have been shown to have prognostic value, such as hyperreflective retinal fields (HRFs) and subfoveal neuroretinal detachment (SND). Methods We conducted a prospective, non-comparative study of treatment-naive patients with DME to evaluate the efficacy of a Pro Re Nata (PRN) regimen of intravitreal dexamethasone implant 0.7 mg (DexI, Ozurdex™). After administration, patients underwent subsequent injections according to PRN criteria in case of edema relapse, but not earlier than 4 months after the previous treatment. Pat…

In Vitro Regeneration of
2019
Three caper (Capparis spinosa L.) biotypes grown on the Sicilian island of Salina (38°33′49″ N) were micropropagated to evaluate two different in vitro culture systems: one using the traditional solid medium, and the other based on liquid culture in a PlantForm bioreactor. PlantForm is a temporary immersion system (TIS), a new propagation method in which the shoots undergo temporary immersion in a liquid medium in order to avoid the accumulation of gas through forced ventilation. This study proposes a protocol to improve the efficiency of in vitro propagation of caper plants, while also reducing production costs, because of the elimination of the gelling agent, and manual labor, requiring l…
Implicación de los microARNs en la hipertensión pulmonar idiopática. Regulación farmacológica
2014
La hipertensión pulmonar (HP) es un desorden complejo que se caracteriza por un aumento progresivo de la presión arterial pulmonar, ocasionado por el remodelado de las arterias pulmonares de pequeño calibre, que origina un aumento de resistencias pulmonares y como consecuencia sobrecarga y fallo del ventrículo derecho que puede llevar al fallecimiento del paciente. La Organización mundial de la salud la clasifica en 5 grupos, en nuestro estudio nos hemos centrado en el grupo I, que se caracteriza por la afección de los vasos pulmonares de pequeño calibre, con una presión arterial pulmonar (PAP) media de ≥ 25 mmHg y ausencia de causas secundarias, este así mismo se subdivide en hipertensión …
