Tumor-derived lactic acid modulates dendritic cell activation and antigen expression.

2005

The tumor milieu can influence dendritic cell (DC) differentiation. We analyzed DC differentiation in a 3-dimensional tumor model and propose a new mechanism of DC modulation by the tumor environment. Monocytes were cultured in the presence of IL-4 and GM-CSF within multicellular tumor spheroids (MCTSs) generated from different tumor cell lines. Monocytes invaded the MCTSs and differentiated into tumor-associated dendritic cells (TADCs). The antigen expression was altered on TADCs independent of the culture conditions (immature/mature DCs, Langerhans cells) and IL-12 secretion was reduced. Supernatants of MCTSs could partially transfer the suppressive effect. Conditioned media from urotheli…

An Analysis of the Immunomodulatory Properties of Human Spheroids from Adipose-Derived Stem Cells

2023

Aims Current methods to induce tolerance following allotransplantation or in autoimmunity carry significant morbidity, and research is very active in investigating alternative methods which could minimize toxicity. Spheroids from adipose stem cells (SASCs) are increasingly gaining interest, they hold a great proliferative and differentiating potential. An immunomodulatory effect has not been investigated on SASCs yet. In this study, we analysed the immunomodulatory properties of SASCs and compared them to ADSCs. Main methods Adipose stem cells (SASCs and ADSCs) and peripheral blood mononuclear cells (PBMCs) were collected from healthy individuals. We analysed the cytokine production and pro…

Proliferative activity and tumorigenic conversion: impact on cellular metabolism in 3-D culture

2001

Oxygen consumption, glucose, lactate, and ATP concentrations, as well as glucose and lactate turnover rates, have been studied in a three-dimensional carcinogenesis model of differently transformed rat embryo fibroblasts (spontaneously immortalized Rat1 and myc-transfected M1, and the ras-transfected, tumorigenic descendants Rat1-T1 and MR1) to determine metabolic alterations that accompany tumorigenic conversion. Various bioluminescence techniques, thymidine labeling, measurement of[Formula: see text] distributions with microelectrodes, and determination of cellular oxygen uptake rates (Q˙[Formula: see text]) have been applied. In the ras-transfected, tumorigenic spheroid types, the size d…

Association between toenail scandium levels and risk of acute myocardial infarction in European men: the EURAMIC and Heavy Metals Study

2002

The association between scandium status and risk of acute myocardial infarction (MI) was examined in a multicentre case control study in 10 centres from Europe and Israel. Scandium in toenails was assessed in 684 cases and 724 controls less than 70 years of age. Mean concentrations of toenail scandium were 6.74 micro/kg in cases and 7.75 microg/kg in controls. Scandium among controls, adjusted for age and centre was positively associated with concentrations of lycopene and oleic acid in adipose tissue (P = 0.002 for both nutrients). Pearson correlations adjusted for age and centre were significant (P0.05) between scandium and lycopene (r = 0.08), zinc (r = 0.08), mercury (r = 0.18) and olei…

“Puffy hand syndrome”

2016

Resume La toxicomanie intraveineuse est responsable de nombreuses complications notamment cutanees et infectieuses. Il existe un syndrome rarement observe en rhumatologie se traduisant par des « grosses mains » : le puffy hand syndrome. Nous en rapportons deux cas rencontres en consultation de rhumatologie chez deux patients toxicomanes. Il s’agit d’un œdeme des mains, bilateral, indolore, ne prenant pas le godet, survenant chez un de nos patients pendant l’intoxication par heroine, et chez l’autre 2 ans apres avoir arrete ses injections. Chez nos deux patients les bilans complementaires (biologiques, radiologiques, echographiques) etaient sans particularite, ce qui a permis dans le context…

Locust neuropeptides stimulating sex pheromone production in female European corn borer moth, Ostrinia nubilalis

1990

Abstract The presence of a pheromonotropically active hormone (PBAN-like substance) from locust organs, ( Locusta migratoria ) has been demonstrated. Extracts of brain, corpora cardiaca, corpora allata, suboesophageal ganglia and thoracic ganglia of L. migratoria caused highly pheromonotropic responses in decapitated females of the European corn borer moth ( Ostrinia nubilalis ). The highest activity per unit weight of tissue was found in the corpora cardiaca and corpora allata of the locust followed by the brain plus suboesophageal ganglion of O. nubilalis . Following 8 days of disconnection, separating the corpora allata from the corpora cardiaca and suboesophageal ganglion, the pheromono…

AbstractMulticellular tumor spheroids (MCTSs) embedded in a matrix are re-emerging as a powerful alternative to monolayer-based cultures. The primary information gained from a three-dimensional model is the invasiveness of treatment-exposed MCTSs through the acquisition of light microscopy images. The amount and complexity of the acquired data and the bias arisen by their manual analysis are disadvantages calling for an automated, high-throughput analysis. We present a universal algorithm we developed with the scope of being robust enough to handle images of various qualities and various invasion profiles. The novelty and strength of our algorithm lie in: the introduction of a multi-step se…

Probing the shape of176Hgalong the yrast line

1998

In-beam \ensuremath{\gamma}-ray and \ensuremath{\gamma}-\ensuremath{\gamma} coincidence measurements have been made for the very neutron-deficient nucleus ${}^{176}\mathrm{Hg}$ using the recoil-decay tagging (RDT) technique. The irregular yrast sequence observed up to $I=10\ensuremath{\Elzxh}$ indicates that the prolate intruder band, seen in heavier Hg isotopes near the neutron midshell, crosses the nearly spherical ground-state band of ${}^{176}\mathrm{Hg}$ above $I=6\ensuremath{\Elzxh}.$
