PGD(2) is the major mediator released by mast cells during allergic responses, and it acts through two different receptors, the D prostanoid receptor 1 (DP1) and DP2, also known as CRTH2. Recently, it has been shown that PGD(2) inhibits the migration of epidermal Langerhans cells to the skin draining lymph nodes (LNs) and affects the subsequent cutaneous inflammatory reaction. However, the role...

We propose a collapse prediction model described in peak ground velocity (PGV) and peak ground displacement (PGD) for steel and reinforced concrete moment-resisting frame buildings. Olsen (2008) simulated the seismic response of eight steel frame buildings to over 60,000 simulated seismic motions; the simulations showed that collapse can be predicted from PGV and PGD. Song and Heaton (2012, als...

P re-implantation genetic diagnosis (PGD) is one of a number of new reproductive/ genetics technologies which have emerged since IVF became widely available. While new reproductive technologies in general have been the subject of sustained sociological interest, PGD initially attracted the attention of scholars from disciplinary backgrounds as diverse as anthropology, ethics, law and government...

Preimplantation genetic diagnosis (PGD) involves testing for specific genetic conditions prior to the implantation [5] of an embryo in the uterine wall. This form of genetic screening has been made possible by the growth of in-vitro fertilization [6] (IVF) technology, which allows for the early stages of development to occur in a laboratory dish rather than in vivo [7]. The purpose of PGD is to...

Preimplantation genetic diagnosis (PGD) was • fi rst applied in 1988 using a polymerase chain reaction (PCR) protocol to amplify a sequence on the Y chromosome for embryo sexing for patients carrying X-linked disease. Patients have to go through in vitro • fertilization (IVF) so that their embryos may be generated in vitro. Cells are removed from oocytes or embryos and used for the genetic diag...

STUDY OBJECTIVE TXA(2) (thromboxane A(2)) is a lipid mediator believed to be produced primarily by platelets in normal subjects, although macrophages are capable of synthesis. There is increased production of TXA(2) in patients with primary pulmonary hypertension (PPH), which may reflect augmented production by macrophages. The objective of this study was to determine if macrophages are activat...

STUDY QUESTION How do data in the 12th annual data collection (Data XII) of the European Society of Human Reproduction and Embryology Preimplantation Genetic Diagnosis (PGD) Consortium compare with the cumulative data for collections I-XI? SUMMARY ANSWER Since the beginning of the data collections, there has been a steady increase in the number of cycles, pregnancies and babies reported annua...

BACKGROUND An increased incidence of aneuploid embryos has been recently described from azoospermic men. The aim of this study was to assess if embryo selection on day 5, based on morphological criteria, would be different from the selection based on PGD for aneuploidy screening (AS) in couples undergoing ICSI for male azoospermia. METHODS Sixty-two cycles of testicular sperm extraction (TESE...
