Impact du système endocannabinoïdien sur la physiologie de l'obésité : effets de l'antagonisme des récepteurs CB1 sur le métabolisme glucido-lipidiqu…
2010
The endocannabinoïd system (ECS) is involved in many biological functions such as regulation of energy metabolism. Recently, several studies have shown an association between obesity and ECS overactivity. In addition, specific CB1R antagonists such as Rimonabant (SR141716) improved metabolic parameters in obese patients essentially through inactivation of central CB1R. However, peripheral CB1R inactivation could also contribute to the improvement of these parameters and it is this notion that we have studied. To this purpose, we tested the effects of SR141716 on obese mice in order to establish relationships between the ECS activity and lipid metabolism by looking more specifically to its r…
Relationship among Body Composition, Adipocytokines, and Irisin on Exercise Capacity and Quality of Life in COPD: A Pilot Study
2022
Adipose tissue is an endocrine organ that interferes with the severity of chronic obstructive pulmonary disease (COPD). Although inflammatory markers, body composition, and nutritional status have a significant impact on pulmonary function, the real contribution of adipocytokines and myokines in COPD is still controversial. We aimed to evaluate the role played by the body composition, leptin, adiponectin, haptoglobin, and irisin on the functional exercise capacity, respiratory function, and quality of life (QoL) in COPD. In 25 COPD (20% GOLD-1; 60% GOLD-2; 20% GOLD-3) patients and 26 matched control subjects, we find that leptin, total adiponectin and haptoglobin are significantly increased…
Adipokines as Biomarkers of Atopic Dermatitis in Adults
2020
Atopic dermatitis (AD) is characterized by chronic, relapsing, pruritic skin inflammation and does not have a well-understood pathogenesis. In this study, we addressed the contribution of adipokines to AD eczema based on the assessment of blood levels of adiponectin, resistin, leptin, lipocalin-2, and vaspin in adult non-obese patients suffering from chronic extrinsic childhood-onset AD. We investigated 49 AD patients with a median age of 37 years. The control group consisted of 30 age-matched healthy subjects. Adipokines were assessed in the serum by ELISA assays and the severity of AD with the SCORing Atopic Dermatitis (SCORAD) index. We found that adiponectin and resistin decreased and l…
The role of adiponectin and leptin in the treatment of ovarian cancer patients
2019
Wprowadzenie: Rak jajnika wykrywany jest najczęściej w zaawansowanym stadium choroby. Jego patogeneza nie jest w pełni poznana, ale przyjmuje się, że odpowiedzialna jest za to podatność organizmu oraz zaburzenia hormonalne. Stale badana jest również rola niektórych cytokin jako czynników predykcyjnych w procesie leczenia. Celem pracy było określenie zależności pomiędzy stężeniem adiponektyny i leptyny a stopniem zaawansowania choroby oraz odpowiedzią na stosowaną chemioterapię. Materiał i metody: Grupa badana składała się z 43 pacjentek leczonych systemowo z powodu raka jajnika. Po zakwalifikowaniu do leczenia pacjentki otrzymały chemioterapię: 5–7 cykli według schematu paklitaksel/karbopla…
Estudio del riesgo cardiovascular en pacientes con Síndrome de Ovario Poliquístico (SOP). Creación de grupos de riesgo.
2015
El SOP es la endocrinopatía más frecuente en la mujer en edad reproductiva. Muchos son los estudios que se han realizado para poder identificar si la presencia del SOP es per se un factor de riesgo cardiovascular. El hecho de que el SOP presente una serie de patologías asociadas que son factores de riesgo cardiovascular hace que sea complicado esclarecer si la elevación del riesgo cardiovascular en estas pacientes se debe fundamentalmente al síndrome. La presencia de factores de confusión como la obesidad y la insulino-resistencia y las interacciones entre ellas y con otros factores de riesgo hacen difícil esta tarea. Los resultados de nuestro estudio indican que las pacientes con SOP prese…
Performing arts and mediation technology in the period of lockdown
2021
Advancements in digital technologies have become novel ways to enrich communication, expression, and transmission of arts knowledge. Technology is increasingly implemented in the performance space, as a source of inspiration for artists. Especially in this period of lockdown, mediation technology has turned out to be an essential tool for different aspects of social life, as in performing arts. With venues, schools and artistic activities closed, performers, students and spectators have been obliged to keep connecting in remote conditions. This article wants to retrace the aesthetic impact of mediation technology in performing arts during this period of lockdown by focusing on the aspects t…
Evolution of Cell Adhesion Systems: Evidence for Arg-Gly-Asp-Mediated Adhesion in the Protozoan Neoparamoeba aestuarina
1995
Developmental processes in multicellular organisms require structural elements, such as adhesion molecules, to stabilize cells at functional positions. In vertebrates, a series of extracellular matrix proteins, e.g. fibronectin and laminin, are involved in cell adhesion. These proteins contain Arg-Gly-Asp [RGD] at their binding sites. Here we show that at concentrations above 2 mM the peptide GRGDSPK, comprising the tripeptide RGD (Arg-Gly-Asp), prevents the adhesiveness of cells of the marine amoeba Neoparamoeba aestuarina. In addition, elevated levels of GRGDSPK cause cells to alter their shapes from those with digitiform subpseudopodia to rounded cells with small lobed pseudopodia. These…

Targeting the Sortase A Transpeptidase to Tackle Gram-positive Pathogens
2013
The virulence factors include the cell-wall associated proteins called MSCRAMMs (microbial surface components recognizing adhesive matrix molecules) that can promote the adhesion to host proteins, for example, the fibronectin that is very common in host tissues. The cellwall associated proteins are necessary for host colonization, invasion, immune evasion and biofilm formation [4]. The biofilms, multistratified bacterial communities that grow on a biological or artificial surface, are responsible for chronic infectious diseases and for device or biomaterial associated infections, and are more resistant to host immune defence system and to conventional antibiotics [5].
