Nonlinear models for fitting growth curves of Nellore cows reared in the Amazon Biome
Revista Brasileira de Zootecnia, 2013 Growth curves of Nellore cows were estimated by comparing six nonlinear models: Brody, Logistic, two alternatives by Gompertz, Richards and Von Bertalanffy.

International Journal of Nursing Sciences, 2023 Objectives: Growth retardation is a risk for premature infants. In addition to demographic and perinatal factors, preterm infants’ physical growth may be affected by neonatal intensive care unit (NICU) stress, maternal postpartum depression, and mother ...

Aging and Wealth Inequality in a Neoclassical Growth Model [PDF]
Review, 2016 In this article, the author uses a version of the neoclassical growth model with overlapping generations of individuals to investigate the effect of aging on wealth inequality. When an economy’s population becomes older—that is, when the proportion of individuals 65 years of age and older increases—two effects are at work: a direct effect from the ...

Mouse models of growth hormone action and aging: A proteomic perspective [PDF]
PROTEOMICS, 2012 Growth hormone ( GH ) is a protein secreted by the anterior pituitary and circulates throughout the body to exert important actions on growth and metabolism. GH stimulates the secretion of insulin‐like growth factor‐ I

International gestational age-specific centiles for umbilical artery Doppler indices: a longitudinal prospective cohort study of the INTERGROWTH-21st Project. [PDF]
, 2020 BACKGROUND: Reference values for umbilical artery Doppler indices are used clinically to assess fetal well-being. However, many studies that have produced reference charts have important methodologic limitations, and these result in significant ...

Estimates of growth and comparisons of growth rates determined from length- and age-based models for populations of purple wrasse (Notolabrus fucicola) [PDF]
, 2005 Growth of a temperate reefa-ssociated fish, the purple wrasse (Notolabrus fucicola), was examined from two sites on the east coast of Tasmania by using age- and length-based models.

Growth, growth modelling and age determination of Pandalus borealis
Marine Ecology Progress Series, 1992 A growth model for pandalid shrimps accounting for seasonal variations in growth is presented based on successive additions of sigmoid functions along a basic von Bertalanffy growth (VBG) equation. Results obtained with this new model are compared with results from the VBG equation and from a VBG model modified by the addition of a sine function ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Oral mucositis is a common and debilitating side effect of childhood cancer and stem cell transplant treatments. It affects the quality of life of children and young people (CYP) and places a strain on services. Photobiomodulation is recommended for oral mucositis prevention in international guidance but is poorly implemented in UK ...
