Adhesion molecules, endothelial products, and microalbuminuria in essential hypertension

2001

Islet beta-cell apoptosis triggered in vivo by interleukin-1beta is not related to the inducible nitric oxide synthase pathway: evidence for mitochon…

2003

IL-1beta is recognized as an effector cytokine contributing to islet beta-cell destruction during diabetes. We have previously shown in vitro that IL-1beta induces nitric oxide (NO) and beta-cell damage. Here, we show that IL-1beta administration in vivo to Wistar rats transiently increases manganese superoxide dismutase activity, whereas inducible NO synthase is not detected, and the levels of nitrate+nitrate do not change. Moreover, a significant decrease of mitochondrial aconitase, leading to a rise of hydroperoxides, and islet beta-cell apoptosis, involving caspase-3 and -8, is observed. Analysis of adhesion molecules in beta-cells showed that intercellular adhesion molecule-1 is highly…

Alternative treatments for oral bisphosphonate-related osteonecrosis of the jaws: a pilot study comparing fibrin rich in growth factors and teriparat…

2013

Objectives: The aim of this study is to describe and compare the evolution of recurrent bisphosphonate-related osteonecrosis of the jaws (BRONJ) in patients treated with plasma rich in growth factors or teriparatide. Material and Methods: Two different types of treatments were applied in patients diagnosed of recurrent BRONJ in a referral hospital for 1.100.000 inhabitants. In the group A, plasma rich in growth factors was applied during the surgery. In the group B, the treatment consisted in the subcutaneous administration of teriparatide. All the cases of BRONJ should meet the following conditions: recurrent BRONJ, impossibility of surgery in stage 3 Ruggiero classification and absence of…

Luspatercept Response in ESA-NaïVe/RS+ Patients and RS- Patients with Low-Intermediate Risk Myelodysplastic Syndromes (MDS)

2016

Abstract Background: Management of anemia is a common therapeutic challenge in patients with myelodysplastic syndromes (MDS). Luspatercept (ACE-536), a fusion protein containing modified activin receptor type IIB, is being developed for treatment of anemia in lower-risk MDS. Luspatercept binds GDF11 and other TGF-β superfamily ligands to promote late-stage erythroid differentiation and increase hemoglobin (Hgb) levels (Suragani R, Nat Med, 2014 and Attie K, Am J Hematol, 2014). Aims: This is an ongoing, phase 2, multicenter, open-label study to evaluate the effects of luspatercept in patient (pts) with low-intermediate risk MDS. Endpoints included erythroid response (IWG HI-E), RBC transfus…

Agouti-related peptide-expressing neurons are mandatory for feeding.

2005

Multiple hormones controlling energy homeostasis regulate the expression of neuropeptide Y (NPY) and agouti-related peptide (AgRP) in the arcuate nucleus of the hypothalamus. Nevertheless, inactivation of the genes encoding NPY and/or AgRP has no impact on food intake in mice. Here we demonstrate that induced selective ablation of AgRP-expressing neurons in adult mice results in acute reduction of feeding, demonstrating direct evidence for a critical role of these neurons in the regulation of energy homeostasis.

Premorbid social adjustment is better in cannabis-using than non-using psychotic patients across Europe

2016

IntroductionA number of authors have hypothesized that psychotic patients who consume cannabis constitute a differentiated subgroup of patients that have better cognitive and social skills, necessary to engage in illegal drug consumption, than non-using patients.ObjectivesGiven that the prevalence, and patterns, of cannabis use are culturally driven, we wanted to study first-episode psychosis (FEP) cannabis-using and non-using patients coming from different European countries as part of the EUGEI-STUDY.AimsWe tested the hypothesis of better premorbid social adjustment in cannabis-using FEP patients, by comparing them to FEP non cannabis users and to their respective healthy controls.Methods…

Effects of Th1 and Th2 cytokines on cytokine production and ICAM-1 expression on synovial fibroblasts

1995

OBJECTIVES--To investigate the influence of the Th1 and Th2 lymphokines interleukins (IL)-4 and IL-13, interferon gamma (IFN gamma), and several monokines on the adhesion of mononuclear cells to synovial fibroblasts and intercellular adhesion molecule-1 (ICAM-1) expression and cytokine production of synovial fibroblasts in patients with osteoarthritis. METHODS--Synovial fibroblasts were isolated from patients with osteoarthritis and stimulated with IL-1 beta, IL-4, IL-6, IL-10, IL-12, IL-13, tumour necrosis factor alpha (TNF alpha), and IFN gamma. Subsequently, we determined the production of IL-1 alpha, IL-1 beta, IL-6, IL-10, IL-12, IFN alpha and TNF alpha, and the expression of ICAM-1 ly…

Treatment with a CO-releasing molecule (CORM-3) reduces joint inflammation and erosion in murine collagen-induced arthritis.

2008

Contains fulltext : 70589.pdf (Publisher’s version ) (Closed access) OBJECTIVE: CO-releasing molecules (CO-RMs) are a novel class of anti-inflammatory agents. We have examined the possible therapeutic effects of CORM-3 in collagen-induced arthritis (CIA). METHODS: Arthritis was induced in DBA-1/J mice by type II collagen. Animals were treated with CORM-3 (5 and 10 mg/kg/day, intraperitoneally) or the inactive compound iCORM-3 (10 mg/kg/day, intraperitoneally) unable to release CO, from days 22 to 31. Production of anti-type II collagen antibodies, cytokines and cartilage olimeric matrix protein (COMP) was evaluated by enzyme-linked immunosorbent assay, and prostaglandin E(2) (PGE(2)) by rad…

Méta-modélisation de l’interception de la lumière dans un couvert cultures: adventices

2017

EAGESTAD DOCT INRA; Dans le modèle parcelle virtuelle de dynamique de la flore adventice, FLORSYS, 70% du temps de calcul est utilisé par le module 3D d’interception de la lumière dont dépend la compétition des cultures et des adventices pour la lumière et la croissance des plantes. Afin d’accélérer le calcul, nous avons utilisé une méthode pour méta-modéliser le module. Cette méthode permet aussi réaliser une analyse de sensibilité. La hauteur et la largeur des plantes ont été identifiées comme des variables primordiales pour prédire l’interception de la lumière par le couvert.

Reciprocal Relations between Adolescents’ Self-Concepts of Ability and Achievement Emotions in Mathematics and Literacy

2021

This longitudinal study examined cross-lagged relations of self-concepts of ability and achievement emotions (i.e., enjoyment, boredom, anxiety) in two central school subjects (i.e., mathematics and literacy). Adolescents (N = 848) reported their achievement emotions and self-concepts of ability four times during Grades 6 and 7. The pattern of results was different for mathematics and literacy subjects. For mathematics the results of random intercept cross-lagged panel models showed a positive reciprocal relationship between self-concepts of ability and enjoyment and a negative reciprocal relationship between self-concept and anxiety. Lower self-concepts of ability in mathematics also predi…
