Association between periodontal disease and non-fatal ischemic stroke: a case-control study
2014
This study aimed to investigate the association between clinical and radiological markers of periodontal disease and ischemic stroke and to assess the potential influence of inflammatory response on the observed associations.A prospective case-control study including a series of 48 cases with a minor ischemic stroke and 47 controls was conducted at the University Hospital of Dijon. Vascular risk factors, clinical dental examination (plaque index, gingival index, percentage of pockets5 mm, percentage of bleeding on probing (BOP) sites), dental panoramic (bone loss) and biological parameters (CRP, total cholesterol, HDL, LDL, fasting glucose) were collected. Conditional regression analyses we…
Peroxisome Proliferator-Activated Receptor Deficiency Increases the Risk of Maternal Abortion and Neonatal Mortality in Murine Pregnancy with or with…
2006
We assessed the implication of peroxisome proliferator-activated receptor (PPAR) alpha deficiency in pregnancy outcome and neonatal survival and in the modulation of T cell differentiation in murine diabetic pregnancy and their offspring. Pregnant wild-type (WT) and PPAR alpha-null mice of C57BL/6J genetic background were rendered diabetic by five low doses of streptozotocin. We observed that, in the absence of diabetes, PPAR alpha deficiency resulted in an increase in abortion rate, i.e. 0% in WT mice vs. 20% in PPAR alpha-null mice [odds ratio (OR) = 14.33; P = 0.013]. Under diabetic conditions, the abortion rate was enhanced, i.e. 8.3% in WT mice vs. 50% in PPAR alpha-null mice (OR = 4.2…
The Serine/Threonine Protein Phosphatase 2A (PP2A) Regulates Syk Activity in Human Platelets
2020
Distinct membrane receptors activate platelets by Src-family-kinase (SFK)-, immunoreceptor-tyrosine-based-activation-motif (ITAM)-dependent stimulation of spleen tyrosine kinase (Syk). Recently, we reported that platelet activation via glycoprotein (GP) VI or GPIb&alpha
Conformation-specific blockade of the integrin GPIIb/IIIa: a novel antiplatelet strategy that selectively targets activated platelets.
2006
Platelet activation causes conformational changes of integrin GPIIb/IIIa (α IIb β 3 ), resulting in the exposure of its ligand-binding pocket. This provides the unique possibility to design agents that specifically block activated platelets only. We used phage display of single-chain antibody (scFv) libraries in combination with several rounds of depletion/selection to obtain human scFvs that bind specifically to the activated conformation of GPIIb/IIIa. Functional evaluation of these scFv clones revealed that fibrinogen binding to human platelets and platelet aggregation can be effectively inhibited by activation-specific scFvs. In contrast to clinically used GPIIb/IIIa blockers, which ar…
Haemostasis in chronic kidney disease
2013
The coagulation system has gained much interest again as new anticoagulatory substances have been introduced into clinical practice. Especially patients with renal failure are likely candidates for such a therapy as they often experience significant comorbidity including cardiovascular diseases that require anticoagulation. Patients with renal failure on new anticoagulants have experienced excessive bleeding which can be related to a changed pharmacokinetic profile of the compounds. However, the coagulation system itself, even without any interference with coagulation modifying drugs, is already profoundly changed during renal failure. Coagulation disorders with either episodes of severe bl…
Haemopoietic effects of 7 alpha, 17 beta dimethyltestosterone.
1979
Some haematic parameters were investigated in female COBS mice treated with 7 alpha, 17 beta Dimethyltestcsterone (DMT). The drug causes an increase of circulating platelets in normal mice. Bone marrow graft from DMT-treated donors facilitates in irradiated mice repopulation of white blood cells and platelets but lowers % survival. These data are interpreted on the basis of a commitment and a loss of self-maintenance induced by DMT on CFUs compartment. © 1979 The Italian Pharmacological Society.
DNA methylation and histone acetylation of rat methionine adenosyltransferase 1A and 2A genes is tissue-specific.
2000
Methionine adenosyltransferase (MAT) catalyzes the biosynthesis of S-adenosylmethionine (AdoMet). In mammals MAT activity derives from two separate genes which display a tissue-specific pattern of expression. While MAT1A is expressed only in the adult liver, MAT2A is expressed in non-hepatic tissues. The mechanisms behind the selective expression of these two genes are not fully understood. In the present report we have evaluated MAT1A and MAT2A methylation in liver and in other tissues, such as kidney, by methylation-sensitive restriction enzyme digestion of genomic DNA. Our data indicate that MAT1A is hypomethylated in liver and hypermethylated in non-expressing tissues. The opposite situ…
Bipolar Quantum Molecular Resonance versus Blunt Dissection tonsillectomy
2015
Bipolar Quantum Molecular Resonance versus Blunt Dissection tonsillectomy. Objectives: This study compared a quantum molecular resonance tonsillectomy (QMRT) to a standard blunt dissection tonsillectomy (BDT) for effectiveness and safety. Methodology: From January 2011 to September 2012, we recruited 80 children (ages 3 to 16 y) with paediatric obstructive sleep apnoea syndrome and/or recurrent tonsillitis. Patients were randomly assigned to receive QMRT (N = 40) or BDT (N = 40). The operating time and blood loss during surgery were evaluated. During the first postoperative week, the patients' parents completed a questionnaire to evaluate bleeding, ear and neck pain, nausea, vomiting, inter…
The Oromo Eschatology: The Prophecy Of Areeroo Boosaroo, Narrated By Borbor Bulee And Guyyoo Dambii
2005
This article provides the first ethnographic account of prophetic text and poetry among the Borana. It was ethnographically constructed by the join efforts of an indigenous anthropologist, an africanist anthropologist, and a Borana oral historian.
Sull'organizzazione sociale tradizionale dei Borana: Contributo al dibattito
1988
This article deals with the traditional social organization of the Borana, an Oromo-speaking pastoral group of Northern Kenya and Southern Ethiopia. A special attention is reserved to the political role of four basic institutions: the kinship system, the gadaa system, the hariyaa system and the qaalluu. Cet article concerne l'organisation sociale des Borana, un groupe pastoral de langue Oromo du Kenya septentrional et de l'Ethiopie méridionale. Une attention particulière est portée au rôle politique de quatre institutions fondamentales: le système de parenté, les systèmes gadaa et hariyaa, et le qaalluu.
