Placenta-derived CD95 ligand causes liver damage in hemolysis, elevated liver enzymes, and low platelet count syndrome.

2004

Background & Aims: The HELLP (hemolysis, elevated liver enzymes, low platelets) syndrome is a life-threatening complication during pregnancy. The associated liver disease may be severe, and maternal hepatic complications may progress to the point that transplantation becomes necessary. CD95 (APO-1, Fas)-mediated apoptosis of liver cells is one of the major pathogenic mechanisms during liver disease. The interaction of CD95 with its ligand, CD95L(FasL), induces apoptosis and thus the source of the death-inducing ligand is critical for understanding the pathomechanism of liver damage involving the CD95-system. Methods: Sera from HELLP patients were analyzed and used in cell culture experiment…

Preeclampsia, a pregnancy-specific disease, is associated with fetal monocyte activation.

2001

The maternal syndrome of preeclampsia is an exclusively pregnancy-related illness involving multiple organs and severe forms may be complicated by HELLP (hemolysis, elevated liver enzymes, low platelets) syndrome. Recently, it has been proposed that both normal pregnancy and preeclampsia are associated with a systemic activation of the nonspecific maternal immune system and that, in particular, monocytes have a central role in the adjustment of maternal immune functions in pregnancy. Here we have investigated the role of the fetal nonadaptive immune system in normal term delivery, uncontrollable preterm labor, and preeclampsia. We demonstrate that spontaneous delivery at term as well as pre…

Distinct subsets of regulatory T cells during pregnancy: is the imbalance of these subsets involved in the pathogenesis of preeclampsia?

2008

Abstract Regulatory T cells (CD4 + CD25 + FoxP3 + -Treg cells) are important regulators of tolerance induction during pregnancy. We now found that the number of CD4 + CD25 + FoxP3 + -Treg cells decreases during normal course of pregnancy and even more so in women affected by preeclampsia. The functional activity of these CD4 + CD25 + -Treg cells was significantly reduced in comparison to those of healthy pregnants. Further analysis revealed two Treg subsets that differed with regard to the FoxP3 and CD25 expression. The percentage of both, CD4 + CD25 + FoxP3 high+ -Treg and CD4 + CD25 high+ FoxP3 + , was maximal in the first and second trimenon, but declined severely in the third trimenon. …

Zastosowanie skorup jaj do usuwania metali ciężkich ze ścieków z instalacji odsiarczania spalin

2018

Przeprowadzono badania skuteczności usuwania kationów Ni, Cu i Cd z roztworów wodnych z zastosowaniem wapienia marglistego, skorup jaj kurzych przeznaczonych do konsumpcji oraz skorup jaj kurzych po wylęgu, których głównym składnikiem jest węglan wapnia. Skorupy jaj kurzych są produktem ubocznym przemysłu spożywczego, który może znaleźć zastosowanie jako zamiennik wapienia marglistego wykorzystywanego do usuwania metali ciężkich z instalacji mokrego odsiarczania spalin. Do badań użyto mieszanych roztworów Ni, Cu i Cd składem zbliżonych do ścieków z instalacji mokrego odsiarczania spalin: Ni (0,526-3,118 mg/dm3 ), Cu (0,483-4,285 mg/dm3 ) i Cd (0,372-0,875 mg/dm3 ). Metale oznaczano metodą a…

The Forgotten Representatives of the School of Mathematics in Sciences of Management

2017

Szybki rozwój technologii, wzrost poziomu życia i zmiany demograficzne przyczyniają się do dynamicznych zmian zachodzących we współczesnym społeczeństwie. Specjaliści w dziedzinie demografii, zwracają szczególną uwagę na zjawisko „starzejącego się społeczeństwa”, co przyczyni sie do wzrostu zapotrzebowania na usługi medyczne świadczone przez lekarzy specjalizujących się w leczeniu ludzi starszych, oraz miejsca w ośrodkach opiekuńczo-leczniczych (sanatoriach czy hospicjach). Głównym celem niniejszego opracowania była ocena pozycji Polski na tle krajów Unii Europejskiej na podstawie wybranych wskaźników charakteryzujących system opieki zdrowotnej. W badaniach starano sie odpowiedzieć na pytan…

Bedrock and soil geochemistry influence the content of chemical elements in wild edible mushrooms (Morchella group) from South Italy (Sicily)

2019

Chemical elements in the samples of wild edible mushrooms of the <em>Morchella</em> group collected from different unpolluted Sicilian sites was analyzed by the ICP-MS (method) to detect the content of their minerals and determine whether soil geology and geochemistry can influence the chemical composition in fungi. Results showed that the mushroom samples mainly contained a high concentration of K and P and a wide variety of minor and trace elements (V, Mo, Pb, Ce, Cs, Zr), including heavy metals. Statistical analysis showed that the mushrooms differed in their content of minor and trace elements based on the geological/geographic site of origin. Comparison with other studies s…

Production technology of early-Hellenistic lime-based mortars from a Punic-Roman residential area at Palermo (Sicily)

2016

The topic of this study was the mineralogical and petrographic characterization of lime-based mortars of Hellenistic-Roman age (3rd century BC), taken from a residential area located in the historical centre of Palermo, near the walls of the Punic-Roman Neapolis, recently brought to light by excavations carried out by the Soprintendenza BB.CC.AA. of Palermo at Palazzo del Gran Cancelliere (Palermo). The collected mortars have been analyzed by optical microscopy (PLM), X-ray powder diffraction analysis (XRPD) and scanning electron microscopy coupled with energy dispersive spectrometry (SEM-EDS). The study was aimed to define the “recipe” (composition of temper and binder, temper size distrib…

Transport de la variabilité dans les matériaux composites = Uncertainties propagation in composite materials

2009

National audience; Dans ce travail, une méthodologie de transport d'incertitudes à travers les différentes échelles d'observation des matériaux composites : (i) micro (fibres et matrice), (ii) méso (pli), (iii) macro (matériau stratifié) est proposée. L'objectif est d'intégrer à l'échelle macro (celle du calcul de structure) l'effet des incertitudes venant de l'échelle micro et celle des incertitudes introduites à chacune des échelles méso et macro. La démarche proposée s'appuie sur l'élaboration dès l'échelle micro de distributions statistiques bâties sur l'analyse morphologique et obtenues grâce à la génération de matériaux virtuels.
