The aim of the study is to determine mechanisms leading to glutathione deficiency in low birth weight newborn babies. Compared to full term neonates, depletion in this population may be due to a decreased synthesis rate or to an enhanced utilization or a combination of both mechanisms.The protocol is constituted of two steps. The objective of the first step is to quantify the blood concentration of glutathione in the artery and the vein of umbilical cord in full term newborn babies. Objectives of the second step are to determine if the glutathione synthesis rate, measured in vitro, is lower in erythrocytes collected from umbilical cord blood of low weight newborn babies compared to full term newborn babies. In this case, the next objective will be to determine if the adjunction of an excess of cysteine in vitro can restore the glutathione synthesis rate in these cells.

The overall purpose of this research is to test whether adding a supplement to the feeding of extremely low birth weight infant (infants weighing less than 2 pound 2 oz at birth) will help...
The goal of the study is to find out how much mercury is in the blood, urine, and stools of premature and low birth weight infants who have received standard childhood vaccines that are gi...
To investigate the relationship of birth weight and childhood blood pressure.
Two groups of preterm infants with birth weight equal to or less than 1500 grams will be studied. One group will receive the standard care and the other will receive standard care plus mat...
Low birth weight (LBW) status (< 10% for gestational age at birth) is associated with increased risk for diseases such as type II diabetes mellitus, hypertension, chronic obstructive pulmo...
To analyze the low weight gain (WG) from birth to 4 and 6wk of life to predict the development of retinopathy of prematurity (ROP) among very low birth weight (VLBW) preterm babies.
In recent years, the prevalence of hypertension and prehypertension increased markedly among children and adolescents, highlighting the importance of identifying determinants of elevated blood pressur...
Twin pregnancies are commonly associated with low birth weight (LBW) infants. Most studies focus on growth of LBW compared with normal infants in singleton. However, there has not been any study on tw...
Birth weight is classified as a risk factor for cardiovascular disease by the World Health Organization, but appropriate preventative interventions remain unclear because the observations have not bee...
We have identified a novel molecular phenotype that defines a sub-group of newborns who have highly-disrupted epigenomes. We profiled DNA methylation in cord blood of 114 children selected from the lo...
An infant having a birth weight of 2500 gm. (5.5 lb.) or less but INFANT, VERY LOW BIRTH WEIGHT is available for infants having a birth weight of 1500 grams (3.3 lb.) or less.
The taking of a blood sample to determine its character as a whole, to identify levels of its component cells, chemicals, gases, or other constituents, to perform pathological examination, etc.
An infant whose weight at birth is less than 1000 grams (2.2 lbs), regardless of gestational age.
An infant whose weight at birth is less than 1500 grams (3.3 lbs), regardless of gestational age.
Development of a library collection, including the determination and coordination of selection policy, assessment of needs of users and potential users, collection use studies, collection evaluation, identification of collection needs, selection of materials, planning for resource sharing, collection maintenance and weeding, and budgeting.
Blood is a specialized bodily fluid that delivers necessary substances to the body's cells (in animals) – such as nutrients and oxygen – and transports waste products away from those same cells. In vertebrates, it is composed of blo...
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
