Striking disparities in access to healthcare and in health outcomes are major characteristics of health across the globe. This inequitable state of global health and how it could be improved has become a highly popularized field of academic study. In a series of articles in this journal the roles of power and politics in global health have been addressed in considerable detail. Three points are...

A total of 25,471 Iranian Holstein heifers distributed in 523 herds of 20 provinces were used to estimate heritability, genetic and phenotypic associations between a number of traits related to the production and reproduction performance. The Animal Breeding Centre of Iran collected the records studied in this research between 1991 and 2001. The traits associated with production were 305-day, 2...

BACKGROUND Preimplantation genetic screening (PGS) provides an opportunity to eliminate a potential implantation failure due to aneuploidy in infertile couples. Some studies clearly show that twins following single embryo transfer (SET) can be the result of a concurrent natural conception and an incidence as high as 1 in 5 twins has been reported. In our case PGS was performed on trophectoderm ...

Coping explicitly with failures during the conception and the design of software development complicates signiicantly the designer's job. The design complexity leads to software descriptions diicult to understand, which have to undergo many simpliications until their rst functioning version. To support the systematic development of complex, fault tolerant software, this paper proposes a layered...

The spontaneous abortion rate in the general population is about 10%. In some women treated with drug regimens for ovulation induction with or without modern assisted reproductive technology (IVF/ICSI etc.) the rate of pregnancy failure is high.

Two hundred and sixty-four cows diagnosed with CCE from day 14 to 42 postpartum were included in this study. A Cox’s proportional hazards regression model with stepwise forward selection for days open was used and the variables type of ...

Currently, about 17% couples in industrialised countries seek medical advice for infertility (Cahill 2002). The definition of infertility is usually the failure to conceive after 1 year of unprotected intercourse (European Society 1996). Infertility can be primary, in women who have never conceived, or secondary, in women who have previously conceived. In the UK, about 10–20% of infertility cas...

BACKGROUND A number of menstrual cycle monitors have been developed to detect the fertile window of the menstrual cycle, mainly for contraceptive purposes. Reliable data on most of these systems are still missing but are urgently needed because many women use them and the tested systems differ enormously in price and effectiveness. We suggest a new efficacy estimating method to evaluate cycle m...
