Introduction The estimation of genetic risks to the offspring of consanguineous marriages, especially those of first cousins, has been exhaustively studied in the literature. Even so the subject still remains controversial, as shown by the results of a recent inquiry performed among medical geneticists and genetic counsellors in the United States by Bennett et al. (1999). In fact, analysing the...
For 0 < α ≤ 2 and 0 < β ≤ 1 the (d,α,β)-superprocess is the superprocess with symmetric α-stable spatial movement in Rd and spectrally positive (1+β)-stable branching. It is a measurevalued process arising as the high density limit of empirical measure for the following critical branching symmetric α-stable particle system. Independent of the others, each particle is assigned a mass n−1 and it ...
This study also rejects arguments made by J&P that immigrants are needed to meet labour shortages, that they bring productivity-increasing economies of scale, and that their children will repay the fiscal burden. New evidence does not provide any grounds for optimism that the offspring of recent immigrants are going to be able to earn enough to compensate current and future generations of Canad...
Background: One of the major factors affecting on male infertility is oxidative stress (OS). Two main sources of ROS production are leukocytes and spermatozoa. The ROS such as tertiary-butyl hydroperoxide (TBHP) may damage and fragmentate to sperm DNA, which can lead to complications in the offspring. In this study, we will investigate the effect of od on DNA fragmentation index (DFI) in sperm ...
Objective(s): Maternal high-fat diet (HFD) consumption has been linked to metabolic disorders and reproductive dysfunctions in offspring. Troxerutin (TRO) has anti-hyperlipidemic, anti-oxidant, and anti-inflammatory effects. This study examined the effects of TRO on apelin-13, its receptors mRNA and ovarian histological changes in the offspring of HFD fed rats. <...
there has been a dramatic rise in the use of assisted reproductive technologies (art), including in vitro fertilization (ivf) throughout the world over the past three decades. because they represent >1% of the birth cohorts in many developed countries, much attention is being paid to the health and well-being of art children. children born after assisted reproductive techniques (art) have an in...
an experiment was conducted to study the effect of metabolizable energy (me) and protein of japanese quails diets on offspring performance and antibody production against sheep red blood cell (srbc). a total of 432 japanese quails (13 week-old) were divided into nine treatments. each treatment comprised four replicates of twelve birds (9 female and 3 male). nine diets including three levels of ...
