A longitudinal and prospective study was carried out at two state-operated maternity hospitals in Belo Horizonte during 1996 in order to assess the weight of preterm appropriate-for-gestational-age newborns during the first twelve weeks of life. Two hundred and sixty appropriate-for-gestational-age preterm infants with birth weight <2500 g were evaluated weekly. The infants were divided into gr...

All organisms are probably exposed to different types of electromagnetic fields (EMFs). This study is an attempt to evaluate the effect of extremely low-frequency EMFs (50 Hz) on some growth parameters and survival rate of common carp fingerling. The fry (n = 120, averaged 16.76 ± 0.88 g in initial weight) was exposed to ELF-EMF at four intensities of 0.1, 0.5, 1 and 2 mT only once for 2 h and ...

placenta plays a vital role in normal fetal development and failure of placenta to gain weight and insufficiency of its function can result in fetal disorders. we performed this study to determine placental weight and factors associated with low weight placentas. in a longitudinal cross-sectional study, women with single pregnancy, and gestational age between 37-42 weeks were studied. the subje...

OBJECTIVE To assess the growth velocity of preterm appropriate for gestational age newborns through growth curves. METHOD A longitudinal and prospective study was carried out at two state-operated maternity hospitals in Belo Horizonte. Two hundred and sixty appropriate for gestational age preterm infants with birth weight < 2,500 g were evaluated weekly for body weight, head circumference and...

OBJECTIVE To explore the intergenerational birth-weight patterns of the direct female descendants of Mexican-American women. DESIGN This is a population-based study. METHODS Stratified analyses were performed on a transgenerational dataset of 1956-1975 and 1989-1991 Illinois computerized vital records of Mexican-American infants. RESULTS Among the descendants of generation 1 US-born Mexic...

AIMS To determine the respiratory health in adolescence of children of birth weight <1501 g, and to compare the results with normal birthweight controls. METHODS Prospective cohort study of children born in the Royal Women's Hospital, Melbourne. Two cohorts of preterm children (86 consecutive survivors 500-999 g birth weight, and 124 consecutive survivors 1000-1500 g birth weight) and a contr...

a {em 2-rainbow dominating function} (2rdf) of a graph $g$ is a function $f$ from the vertex set $v(g)$ to the set of all subsets of the set ${1,2}$ such that for any vertex $vin v(g)$ with $f(v)=emptyset$ the condition $bigcup_{uin n(v)}f(u)={1,2}$ is fulfilled, where $n(v)$ is the open neighborhood of $v$. the {em weight} of a 2rdf $f$ is the value $omega(f)=sum_{vin v}|f (v)|$. the {em $2$-r...

the objective of this study is to determine risk factors causing increase in very low birth way (vlbw) neonatal mortality. the medical files of all neonates weighing ≤1500 g, born in vali-e-asr hospital (2001-2004) were studied. two groups of neonates (living and dead) were compared up to the time of hospital discharge or death. a total of 317 neonates were enrolled. a meaningful relationship e...

abstract 900 rainbow trout (mean weight 25 gr) were obtained from a local fish farm in urmia city and after acclimatization for 10 days, the fish were randomly divided into four groups (with three replication) and fed for 8 weeks with 0 (control), 2/5, 5 and 10 g chitosan/kg feed, respectively. finally treatments were fed the control diet (without any chitosan) for another 3 weeks. body weight,...

background: &beta-glucans; are glucose polymers with a variety of stimulatory effects on the immune system. the objective of this study was to evaluate the immune-enhancing activities of low molecular weight gamma irradiated &beta-glucan; (i&beta-g;) extracted from pleurotus ostreatus in response to pseudomonas aeruginosa infection in rats. materials and methods: &beta-glucan; (&beta-g;) powder...
