Prismatic binocular dissociation was used during infancy to mimic conditions of strabismus in macaque infants. Prisms worn continuously produce a diplopia unfavorable for the maintenance and development of the binocular visual system. Prism-reared monkeys were tested as young adults and found to be permanently stereoblind for dynamic random dot stereograms. ...

An infant with a 46XY karyotype was born with ambiguous genitalia, including microphallus and perineal hypospadias. A female gender was assigned due to extreme failure of development of the external genitalia. Subsequent investigations demonstrated panhypopituitarism, and it is believed that severe gonadotrophin deficiency was responsible for the intersex state. This ...

Female sifaka mate selectively with one or more resident and/or non-resident males during the breeding season. Various adaptive explanations have been advanced to explain why female primates mate with multiple males including that 1) females seek to confuse paternity and thereby forestall male infanticide and/or ensure male infant care or ...

BACKGROUND: Bone marrow monosomy 7 is an uncommon disorder of the pluripotent stem cells that leads to frequent childhood infections and leukemia. Primary adrenal hypoplasia occurs very rarely and is incompatible with life. Male pseudohermaphroditism results from inadequate androgen secretion or inappropriate androgen action. We report a case of monosomy ...

It appears from the evidence documented in this Commentary that the neonatal period is another critical stage in the process of sexual, behavioural and immune system development and maturation in primates. Interference with normal brain-pituitary-gonadal function during this period (e.g. with a GnRH analogue in monkeys) appears to impact adversely ...

There is increasing evidence for an important role of adverse early experience on the development of major psychiatric disorders in adulthood. Corticotropin-releasing factor (CRF), an endogenous neuropeptide, is the primary physiological regulator of the mammalian stress response. Grown nonhuman primates who were exposed as infants to adverse early rearing conditions ...

Research has demonstrated that human infants and nonhuman primates have a rudimentary numerical system that enables them to count objects or events. More recently, however, studies using a preferential looking paradigm have suggested that preverbal human infants are capable of simple arithmetical operations, such as adding and subtracting a small ...

A large Sicilian kinship in which myotonic dystrophy (DM) affected spanning four generations is presented. The pedigree clearly illustrates the phenomenon of anticipation, and illustrates that this phenomenon is more marked when transmission occurs through an affected female rather than an affected male. The pedigree is interpreted in light of ...

Previous studies of macaques have failed to show a relationship between female reproductive condition and infant-directed behavior. This has led to the view that maternal responsiveness in nonhuman primates is independent from hormonal variables and is mainly regulated by social and experiential factors. The present study reports longitudinal data on ...
Kutteh W H - - 1995
Every year approximately one in 5000 babies is born with ambiguous genitalia, a condition that requires immediate sex assignment if possible. We investigated whether transabdominal ultrasonography with the use of a linear array high-resolution 7.5-MHz transducer would enhance the accuracy of detecting the uterus in the newborn. One hundred mothers ...

Meconium peritonitis results from in utero perforation of the bowel and subsequent spillage of meconium into the peritoneal cavity. Free communication of the peritoneal space with the processus vaginalis during gestation permits formation of a meconium hydrocele. Meconium hydrocele has been reported in the newborn scrotum but to our knowledge ...

In an earlier study, we found no effects of 60 Hz electric and magnetic fields (EMF) from a 500 kV transmission line on serum melatonin patterns or on puberty in ten female Suffolk lambs (Ovis aries). We conducted a larger replicate study of 15 lambs exposed to a mean electric ...
Grant V J - - 1994
Previous research (Grant, 1990, 1992) suggests that the sex of the infant is linked to maternal dominance, although it is unclear from existing studies whether women have obtained higher dominance ratings merely as a consequence of already carrying a male foetus. In an effort to overcome this problem, self-report personality ...
