Quantum logic gates by adiabatic passage

2006

International audience; We present adiabatic passage techniques for the realisation of one and two-qubit quantum Gates. These methods use evolution along dark-states of the system, avoiding decoherence effects such as spontaneous emission. The advantage of these methods is their robustness: they are insensitive to the fluctuations of the parameters and to partial knowledge of the system.

Spontaneous Resolution of Delayed Suprachoroidal Hemorrhage in the Single Eye Following Needling in Congenital Glaucoma

2017

Suprachoroidal hemorrhage (SCH) is a rare, but potentially vision-threatening event with poor long-term visual prognosis. At present, there is disagreement whether surgical intervention or conservative treatment is superior in the management. We report on a case of spontaneous resolution of severe SCH after needling procedure in the only eye of a young patient with congenital glaucoma.A 43-year-old woman with congenital glaucoma was scheduled for bleb needling in her only eye. Preoperative best-corrected visual acuity was 20/40 and intraocular pressure 20 mm Hg. On the third postoperative day, she developed a massive delayed SCH with appositional (kissing) choroidal bullae and visual acuity…

Serum and ascitic fluid bacterial DNA: a new independent prognostic factor in noninfected patients with cirrhosis.

2008

We tested the hypothesis that the presence of bacterial DNA (bactDNA) in ascitic fluid and serum is associated with decreased survival in patients with cirrhosis. In a prospective, multicenter study, we analyzed the clinical evolution of 156 patients with cirrhosis and ascites (first or recurrence) with lower than 250 polymorphonuclear cells (PMN)/L, negative ascites bacteriological culture, and absence of other bacterial infections being admitted for evaluation of largevolume paracentesis, according to the presence of bactDNA at admission. Survival, causes of death, and successive hospital admissions were determined during a 12-month follow-up period. BactDNA was detected in 48 patients. T…

Quantitative methylation analysis of developmentally important genes in human pregnancy losses after ART and spontaneous conception.

2009

To study possible effects of assisted reproductive technologies (ART) on epigenetic reprogramming, we have analyzed the DNA methylation levels of differentially methylated regions (DMRs) of seven imprinted genes (H19, MEG3, LIT1, MEST, NESP55, PEG3 and SNRPN) as well as the promoter regions of the pluripotency gene NANOG and the tumor suppressor gene APC in chorionic villus samples (CVS) of 42 spontaneous miscarriages and stillbirths after ART and 29 abortions/stillbirths after spontaneous conception. We did not find an increased rate of faulty methylation patterns after ART, but significant and trend differences (ROC curve analysis, Wilcoxon test) in the methylation levels of LIT1 (P = 0.0…

A very rare cause of retroperitoneal bleeding in young patients: do not forget the occurrence of a ruptured left gastroepiploic artery aneurysm!

2019

Visceral artery aneurysms represent a very rare condition. The affected patients usually present as emergency secondary to the sudden rupture of the aneurysm or as an incidental finding on imaging. In this setting, gastric and gastroepiploic aneurysms account for only about 4% of all the splancnic aneurysms. Since ruptured visceral aneurysms present a high mortality, a prompt and adequate (surgical or radiological interventional) treatment is mandatory. Due to the difficulty in achieving an adequate transcatheter access in some cases the emergency laparotomy may represent the only chance for the recover of the affected patients. We report two cases of ruptured left gastroepiploic aneurysms …

Plasma viscosity pattern and erythrocyte aggregation in two patients with congenital afibrinogenemia

2020

: In this case report, we examine the behavior of plasma viscosity, explored at high and low shear rates, and erythrocyte aggregation in two patients with congenital afibrinogenemia, a clinical disorder firstly described in 1920 and that has an estimated incidence of 1 : 1-200 0000. The two hemorheological parameters examined by us showed a marked decrease in both patients, in one of whom erythrocyte aggregation was even undetectable. Keeping in mind that spontaneous thrombosis (venous and arterial) has been often described in congenital afibrinogenemia, it can be hypothesized that the decrease in plasma viscosity and erythrocyte aggregation might cause a reduction of the endothelial synthe…

HLA-DRB1*1301 AND *1302 protect against chronic hepatitis B

1997

Abstract Background/Aims: The outcome of acute hepatitis B infection may be influenced by host factors like the major histocompatibility complex (MHC). We have investigated MHC class I and class II antigens in patients with chronic hepatitis B compared to a healthy control population. To confirm the findings of this first study we performed a second study in a group of subjects who had spontaneously recovered from acute hepatitis B infection. Methods: Frequencies of MHC class I and class II antigens were analyzed in patients with chronic hepatitis B virus infection and in control subjects. MHC class I typing was done by standard microlymphocytotoxicity assays. DRB1 and DQA1 genotypes were d…

Short- and long-term effects of the transjugular intrahepatic portosystemic shunt on portal vein thrombosis in patients with cirrhosis

2011

Background and aims Portal vein thrombosis (PVT) negatively impacts the prognosis in patients with cirrhosis. The aim of our study was to evaluate the effects of transjugular intrahepatic portosystemic shunt (TIPS) placement in patients with cirrhosis complicated by PVT. Methods Seventy consecutive cirrhotic patients with non-tumoural PVT treated with TIPS for portal hypertension complications from January 2003 to February 2010 in a tertiary-care centre were followed until last clinical evaluation, liver transplantation, or death. Results TIPS was successfully placed without major procedure-related complications. After TIPS, the portal venous system was completely recanalised in 57% of pati…
