PURPOSE The ZAP-70 gene is normally expressed in T and natural killer cells, where it is required for the T-cell receptor (TCR) signaling. More recently, it has been described that ZAP-70 contributes to the B-cell development at early stages of B-cell differentiation in mice. The purpose was to investigate the presence of ZAP-70 in normal pro/pre B cells and mature B cells and in tumoral cells ...
OBJECTIVE To assess the effect of pre-lacteal feeding on full breastfeeding in the first six months of life in selected hospitals, Nairobi Province. Pre-lacteal feeding has been internationally discouraged because of its negative effect on the duration of breastfeeding. METHODS A prospective cohort design was used with a sample of 692 mother-infant pairs recruited at birth and followed up unt...
The ratio of males to females in 1061 babies born to mothers with toxemia of pregnancy is 1.24. The ratio increases as the severity of the disease increases, being 1.71 in cases in which the urinary output of protein is equal to or greater than 3 grams per 24 hours. Histoincompatibility of the fetus and mother, including incompatibility due to an antigen (or antigens) dependent on the Y chromos...
In light of cross-cultural and experimental research highlighting effects of childrearing practices on infant motor skill, we asked whether wearing diapers, a seemingly innocuous childrearing practice, affects infant walking. Diapers introduce bulk between the legs, potentially exacerbating infants' poor balance and wide stance. We show that walking is adversely affected by old-fashioned cloth ...
Urine pH was monitored on a large Midwest dairy, where 161 multiparous cows received CLOSE-UP PELLET as part of their pre-fresh ration (Technical Service Bulletin #308). Pre-calving urine pH among the 8 mature cows treated for milk fever averaged 7.51, while mean urine pH among the 153 other cows was 7.61. At 5.0%, the incidence rate of milk fever was low for multiparous cows. A typical milk fe...
BACKGROUND A proportion of neonatal deaths from asphyxia have been shown to be associated with pre-existing brain injury. OBJECTIVES (a) To compare the epidemiology of infants displaying signs of birth asphyxia with those not showing signs; (b) to examine the neuropathology and determine if possible the timing of brain insult comparing asphyxiated with non-asphyxiated infants; (c) to compare ...
BACKGROUND Maternal pre-pregnancy obesity may be associated with impaired infant neuropsychological development; however, there are few studies and it is unclear if reported associations are due to intrauterine mechanisms. METHODS We assessed whether maternal pre-pregnancy overweight and obesity were associated with cognitive and psychomotor development scores (mean 100 ± 15) of children aged...
