Bone mineral density during pregnancy in women participating in a randomized controlled trial of vitamin D supplementation
bone mineral content bone mineral density cholecalciferol pregnancy vitamin D
2018/11/21
Background: Little is known about bone mineral density (BMD) during pregnancy. Advances in technology with lower radiation emissions by dual-energy X-ray absorptiometry instruments now permit the safe...
Factors Affecting the Incidence of Angel Wing in White Roman Geese: Stocking Density and Genetic Selection
Angel Wing Stocking Density Genetics White Roman Geese
2016/7/27
The present study investigated stocking density and genetic lines, factors that may alter the severity and incidence of angel wing (AW), in White Roman geese. Geese (n = 384) from two genetically sele...
Low-density Lipoprotein Improves Motility and Plasma Membrane Integrity of Cryopreserved Canine Epididymal Spermatozoa
Low-density Lipoprotein Epididymal Spermatozoa Cryopreservation Dog
2016/5/20
Cryopreservation of caudal epididymal spermatozoa is an effective technique to conserve genetic potentials of superior dogs when it is not possible to collect ejaculated spermatozoa. Although hen egg ...
Tree size frequency distributions, plant density, age and community disturbance
Allometry community ecology plant size stem diameter
2015/8/27
We show that explicit mathematical and biological relationships exist among the scaling exponents and the allometric constants (a and b, respectively) of log–log linear tree-community size frequency d...
Visceral adiposity is negatively associated with bone density and muscle attenuation

A whole genome association (WGA) study was performed to detect significant polymorphisms for meat quality traits in an F2 cross population (N = 478) that were generated with Korean native pig sires an...
Some Exact Self-Similar Solutions to a Density-Dependent Reaction-Diffusion Model
Exact Self-Similar Density-Dependent Reaction-Diffusion Model Biological Physics
2012/4/20
In this paper, we investigated a density-dependent reaction-diffusion equation, $u_t = (u^{m})_{xx} + u - u^{m}$. This equation is known as the extension of the Fisher or Kolmogoroff-Petrovsky-Piscoun...
Stripe formation in bacterial systems with density-suppressed motility
Stripe formation bacterial systems density-suppressed motility Biological Physics
2012/5/3
Engineered bacteria in which motility is reduced by local cell density generate periodic stripes of high and low density when spotted on agar plates. We study theoretically the origin and mechanism of...
Relationships of Plasma and Very Low Density Lipoprotein Lipids and Subfractions with Abdominal Fat in Chickens
