Proper Generalized Decomposition (PGD) is a method which consists in looking for the solution to a problem in a separate form. This approach has been increasingly used over the last few years to solve mathematical problems. The originality of this work consists in the association of PGD with a spectral collocation method to solve transfer equations as well as Navier–Stokes equations. In the fir...

Background: Little is known about the development of Prolonged Grief Disorder (PGD) symptoms over time in adults. For clinical purposes, it would be useful to have knowledge about early indicators of a problematic grief trajectory. Objective: This study aimed to identify classes of bereaved individuals with similar trajectories of PGD symptoms and to design a provisional screening tool includin...

Over the past years, model reduction techniques have become a necessary path for the reduction of computational requirements in the numerical simulation of complex models. A family of a priori model reduction techniques, called Proper Generalized Decomposition (PGD) methods, are receiving a growing interest. These methods rely on the a priori construction of separated variables representations ...

We have applied a new method of genetic analysis, called 'minisequencing', to preimplantation genetic diagnosis (PGD) of monogenic disorders from single cells. This method involves computer-assisted mutation analysis, which allows exact base identity determination and computer-assisted visualization of the specific mutation(s), and thus facilitates data interpretation and management. Sequencing...

Aspirin and other nonsteroidal anti-inflammatory drugs prevent some cases of colon cancer by inhibiting prostaglandin (PG) synthesis. PGE(2) promotes colon neoplasia, as shown by knockout mouse studies on enzymes and receptors in the PG cascade. A few experiments 20 to 30 years ago suggested that PGD(2) may suppress tumors, but a role for biosynthetic enzymes for PGD(2) in tumor development has...

A large body of evidence has implicated prostaglandin E(2) (PGE(2)) in fever production. However, the role of PGD(2) in this context is only poorly understood. We therefore determined by LC-MS/MS analyses the content of PGD(2) and PGE(2) in cerebrospinal fluid (CSF), plasma and lungs of rats over 5 hours after fever induction by intraperitoneal injection of lipopolysaccharide (LPS, 50 microg/kg...

Phosphogluconate dehydrogenase (PGD) and xanthine dehydrogenase (XDH) were genetically studied by agar gel electrophoresis in the mosquito Aedes togoi. Adult homogenates displayed banding patterns with one zone of activity of either enzyme. Eight backcrosses were conducted to map the two loci, Pgd and Xdh, to linkage group III with the following arrangement: Pgd--(ca. 15 map units)--bl (bleache...

Results 36 patients were included. Among them, 13 (36 %) had grade 3 PGD. EVLWi was significantly higher in the grade 3 PGD group at ICU admission, day one and at day 2. A cut-off value of 14 ml/kg of EVLWi at admission predicts the progression to grade 3 PGD with a sensitivity of 82% and a specificity of 77% and was significantly associated with the need for rescue therapy for severe hypoxemia...

Among the many educational materials produced by the European Society of Human Reproduction and Embryology (ESHRE) are guidelines. ESHRE guidelines may be developed for many reasons but their intent is always to promote best quality practices in reproductive medicine. In an era in which preimplantation genetic diagnosis (PGD) has become a reality, we must strive to maintain its efficacy and cre...

OBJECTIVE To examine whether embryo biopsy for preimplantation genetic diagnosis (PGD) influences neonatal outcomes. DESIGN Prospective follow-up cohort. SETTING Tertiary university-affiliated medical center. PATIENT(S) 242 children born after PGD, 242 children born after intracytoplasmic sperm injection (ICSI) (158 singletons and 42 twins pairs in each group), and 733 children born after...
