Stimulation of the ADRB3 Adrenergic Receptor Induces Relaxation of Human Placental Arteries: Influence of Preeclampsia1

2006

Preeclampsia, which complicates 3-8% of pregnancies, is one of the leading causes of neonatal morbidity and mortality. Its pathophysiology remains unclear. The aim of the present study was to investigate the presence and the role of beta2- and beta2-adrenergic receptors (ADRB2 and ADRB3, respectively) in human placental arteries and to assess the influence of preeclampsia on ADRB responsiveness. SR 59119A, salbutamol, and isoproterenol (ADRB3, ADRB2, and nonselective ADRB agonists, respectively) induced a concentration-dependent relaxation of placental artery rings obtained from women with uncomplicated or preeclamptic pregnancies. SR 59119A-induced relaxation was unaffected by the blockade…

Response to reindeer grazing removal depends on soil characteristics in low Arctic meadows

2014

In Arctic tundra, grazing is expected to exert a positive influence on microbial activity thus enhancing nutrient cycling and promoting the presence of high productive graminoids. We investigated the changes occurring in two low Arctic meadow sites after 10 years exclusion from grazing. We compared plant, soil fauna and microbial community composition, extracellular enzymes activities, and soil nutrients in ungrazed and adjacent grazed area in two low Arctic meadows. The two closely located experimental sites were both dominated by the common grass Deschampsia flexuosa which covered more than 50% of the meadows. Plant community was affected significantly by site and grazing, but the effect …

Plant diseases a herald of environmental changes

2011

Environmental changes can alter morphology and physiology of plants, and geographic distribution of both wild and cultural species. All these modifications reflect in plant-associated microflora and development of plant pathogens as well. Climate warming causes a pole-ward shift not only different plants but also their pathogens.

Sex ratio operativa della popolazione di Paracentrotus lividus (Lam.) nell’AMP Isola di Ustica

2006

Nell’AMP ”Isola di Ustica” l'instaurazione del regime di protezione, e quindi del divieto di prelievo, ha provocato un aumento della densità del riccio edule Paracentrotus lividus (Lam.) con conseguenze negative sulle comunità algali. L’intenso pascolo di questi echinidi regolari ha infatti trasformato la fascia superficiale sommersa in un barren ground, area a bassa complessità e diversità. Una buona stima della sex ratio operativa (OSR) di P. lividus può chiarire aspetti importanti della dinamica di popolazione di questa specie ed essere di notevole aiuto in una logica di intervento gestionale. Scopo del lavoro è stato quello di valutare la OSR della popolazione di P. lividus presente nel…

Anorectal malformations and pregnancy-related disorders: a registry-based case-control study in 17 European regions

2013

Objective To identify pregnancy-related risk factors for different manifestations of congenital anorectal malformations (ARMs).Design A population-based case-control study.Setting Seventeen EUROCAT (European Surveillance of Congenital Anomalies) registries, 1980-2008.Population The study population consisted of 1417 cases with ARM, including 648 cases of isolated ARM, 601 cases of ARM with additional congenital anomalies, and 168 cases of ARM-VACTERL (vertebral, anal, cardiac, tracheo-esophageal, renal, and limb defects), along with 13371 controls with recognised syndromes or chromosomal abnormalities.Methods Multiple logistic regression analyses were used to calculate adjusted odds ratios …

Hemostatic Abnormalities in Patients With Severe Preeclampsia

2007

Preeclampsia is the most common medical disorder of pregnancy. Early onset preeclampsia is defined as presentation of hypertension and proteinuria before 34 weeks of gestation. Alterations of endothelial cells and fibrin deposition in microvasculature lead to enhanced activation of the coagulation cascade and impaired fibrinolysis associated with multiple organ dysfunctions. Plasma samples were obtained from 50 patients with severe preeclampsia before 34 weeks of gestation and in 61 patients with late preeclampsia. Factor VIIIR:Ag, fibrinogen, D-dimer, and thrombomodulin increased with advanced pregnancy. The platelet count is very important because of the close correlation with the activa…

Recurrent cerebral ischaemia in a pregnant woman with patent foramen ovale II° and thrombophilia.

2014

SummaryThis case report concerns a pregnant multipara (age: 27 years) in the 16th gestational week. She developed a sudden onset of paraesthesia in her left lower arm although injecting dalteparin 5000 IU once daily subcutaneously (s. c.) due to a heterozygous factor V Leiden mutation and a prior miscarriage in the first pregnancy and preeclampsia in her third pregnancy. After the miscarriage she delivered two healthy children under prophylactic anticoagulation with low molecular weight heparin (LMWH). Now via magnetic resonance imaging (MRI) she was diagnosed as having multiple cerebral ischaemic lesions. Further workup revealed the presence of a patent foramen ovale (PFO) II° but no venou…
