in western countries we assist at the paradox that fertility is socially discouraged by a mindset that depicts fertility as a resource to exploit as late as possible. so, couples have high expectative about the advantages of delayed parenthood, but they are scarcely informed about its risks. scientific data suggests to anticipate the first pregnancy, but social pressures impose to wait, though ...
Pediatric AIDS typically follows transmission of human immunodeficiency virus type 1 (HIV-1) from infected mothers to their offspring. The possibility that infected maternal-origin cells serve as a conveyance for mother-to-child HIV-1 transmission was investigated in a rabbit infection model. Administration of HIV-1-infected human T cells to pregnant rabbits was followed by evaluation of offspr...
BACKGROUND The mechanisms through which allergies can be inhibited after preconception immunization with allergens are not fully understood. We aimed to evaluate whether maternal immunization can induce a regulatory B (B10) cell population in offspring in concert with allergy inhibition. METHODS C57BL/6 females were or were not immunized with OVA and were mated with normal WT males. Their off...

Human offspring are weaned earlier than the offspring of other great apes but take longer to reach nutritional independence. An analysis of human disorders of imprinted genes suggests genes of paternal origin, expressed in infants, have been selected to favor more intense suckling than genes of maternal origin. The same analysis suggests that genes of maternal origin may favor slower childhood ...
background substance abuse during pregnancy leads to considerable adverse effects in mothers and their infants. objectives the purpose of this study was to evaluate perinatal complications in opium-addicted mothers and their newborns, exposed to opium in utero. patients and methods during a one-year period (2008 - 2009), 45 opium-addicted mothers and their newborns were enrolled in a case-contr...
Exposure to adversity in utero at a sensitive period of development can bring about physiological, structural, and metabolic changes in the fetus that affect later development and behavior. However, the link between prenatal environment and offspring outcomes could also arise and confound because of the relation between maternal and offspring genomes. As human studies cannot randomly assign off...
Reproductive success is widely used as a measure of fitness. However, offspring quantity may not reflect the genetic contribution to subsequent generations if there is nonrandom variation in offspring quality. Offspring quality is likely to be an important component of human fitness, and tradeoffs between offspring quantity and quality have been reported. As such, studies using offspring quanti...
UNLABELLED Centenarians' offspring represent a suitable model to study age-dependent variables (e.g. IGF-I) potentially involved in the modulation of the lifespan. The aim of the present study was to investigate the role of the IGF-I in human longevity. We evaluated circulating IGF-I bioactivity measured by an innovative IGF-I Kinase Receptor Activation (KIRA) Assay, total IGF-I, IGFBP-3, total...
