Evaluation of gestation length and birth weight of offspring of Polish native cattle breeds in context of estimating genetic parameters
pregnancy birth body weight heritability native breed
2018/11/23
Research material included data on gestation length of 15 436 cows of Polish native breeds. These were: White Backed (BG; 324 records), Polish Red (RP; 5396 records), Polish Black and White (ZB; 3508 ...
Effect of maternal high dosages of folic acid supplements on neurocognitive development in children at 4–5 y of age: the prospective birth cohort Infancia y Medio Ambiente (INMA) study
folic acid supplements folate pregnancy periconception period child neurocognitive development
2018/11/16
Background: The benefits of the use of folic acid supplements (FASs) during the periconception period to prevent neural tube defects and to ensure normal brain development in offspring are well known....
Prospective associations of maternal betaine status with offspring weight and body composition at birth: the Growing Up in Singapore Towards healthy Outcomes (GUSTO) cohort study
betaine pregnancy birth weight infants adiposity
2018/12/18
Background: Betaine supplementation results in lower body weight and fat mass and higher lean mass in animals and adult humans. However, the relation between maternal betaine status and offspring birt...
Comparison of associations of maternal peri-pregnancy and paternal anthropometrics with child anthropometrics from birth through age 7 y assessed in the Danish National Birth Cohort
intrauterine environment intergenerational relations parental BMI parental overweight child anthropometry childhood overweight
2018/12/3
Background: Maternal prepregnancy adiposity may influence child adiposity beyond the transmitted genetic effects, which, if true, may accelerate the obesity epidemic, but the evidence for this mechani...

Mineral- and vitamin-enhanced micronutrient powder reduces stunting in full-term low-birth-weight infants receiving nutrition, health, and hygiene education: a 2 × 2 factorial, cluster-randomized trial in Bangladesh
full-term low-birth-weight infant hand hygiene hand sanitizer infants infection linear growth low birth weight micronutrient powder
2018/11/30
Background: The causes of stunting are complex but likely include prenatal effects, inadequate postnatal nutrient intake, and recurrent infections. Low-birth-weight (LBW) infants are at high risk of s...
ROLE OF FETAL THIGH CIRCUMFERENCE IN ESTIMATION OF BIRTH WEIGHT BY ULTRASOUND
Estimated Birth Weight Thigh Circumference
2015/8/3
To evaluate the accuracy and usefulness of predicting birth weight by measuring fetal thigh circumference by ultrasound. METHODS: In 110 pregnant women, fetuses without structural or chromosomal anoma...
Traveling waves for the Keller-Segel system with Fisher birth terms
Chemotaxis Traveling waves Keller-Segel system Reaction diffusion systems Nonlinear stability
2015/7/14
We consider the traveling wave problem for the one dimensional Keller-Segel system with a birth term of either a Fisher/KPP type or with a truncation for small population densities. We prove that ther...
SEPARATION CUT-OFFS FOR BIRTH AND DEATH CHAINS。

Probability the space independent index variable parameter the dirichlet conditions
2015/7/8
The purpose of this paper is to present a probabilistic proof of the well-known result stating that the time needed by a continuous-time finite birth and death process for going from the left en...
The Wartime Bridge Reliability Evaluation Model Based on Birth-and-Death Process
Wartime Bridge Reliability Evaluation Birth-And-Death Process
2013/1/30
At first, the concept of bridge reliability is given, followed with its mathematic model. Then, based on the analysis about the mechanism of the damage and repair of bridges, and the state diversion o...
