Nerve growth factor concentration in human saliva

Oral Diseases, 2007
Objective:  The aims of this study were to measure the normal concentration of nerve growth factor (NGF) in healthy human saliva and to investigate the effects of age and gender differences on saliva NGF level.Materials and methods:  Resting whole, stimulated parotid, and stimulated submandibular/sublingual saliva were collected from 127 healthy ...

Reductions of vascular endothelial growth factor and placental growth factor concentrations in severe preeclampsia

American Journal of Obstetrics and Gynecology, 2000
The aim of this study was to determine whether plasma concentrations of vascular endothelial growth factor and placental growth factor are altered in women with severe preeclampsia.We performed a case-control study to compare plasma concentrations of vascular endothelial growth factor and placental growth factor between women with severe preeclampsia ...

Growth and Product Differentiability as Factors Influencing Changes in Concentration

The Journal of Industrial Economics, 1974
concentration reducing force because smaller firms and potential entrants are encouraged to expand (or enter) during rapid growth periods since they can do so without encroaching on the market of existing firms.' This hypothesis has been examined empirically but the results are conflicting.2 The second hypothesis is that concentration is more likely to

On the concentration profile of a growth inhibitory factor in multicell spheroids

Mathematical Biosciences, 1993
A mathematical model is presented for the production of a growth inhibitory factor (GIF) within a multicell spheroid. The main assumption of the model is that the GIF is produced by cells within the spheroid in some prescribed nonlinear, spatially dependent manner.

Effect of concentrated growth factor on osteoblast cell response

Journal of Stomatology, Oral and Maxillofacial Surgery, 2018
The purpose of this study was to assess the effect of concentrated growth factor (CGF) on osteoblast cell proliferation and differentiation.SaOS-2 osteoblast-like cells were cultured on titanium discs. The disc surfaces in the test group were treated with CGF serum, and those in the control group were left untreated.

The Effect of Concentrated Growth Factors in the Treatment of Periodontal Intrabony Defects [PDF]

open access: yesFuture Science OA, 2016
To investigate the effect of concentrated growth factors (CGFs) in human intrabony defect treatment.Thirty-one intrabony defects were randomly treated with CGFs + bovine porous bone mineral (BPBM) or BPBM alone. Probing depth, clinical attachment level and hard tissue fill were evaluated at baseline and 1 year post surgery.No differences in any of the ...

Quantile-specific heritability of serum growth factor concentrations

Growth Factors, 2021
"Quantile-dependent expressivity" occurs when the effect size of a genetic variant depends upon whether the phenotype (e.g. growth factor concentration) is high or low relative to its distribution.Quantile-regression analysis was applied to family sets from the Framingham Heart Study to determine whether the heritability (h2) of vascular endothelial ...

Concentrations of Epidermal Growth Factor and Transforming Growth Factor-Alpha in Preterm Milk

2004
Human milk is the major source of nutrients and growth promoting substances in the first weeks of life for the majority of neonates (Goldman 2000). As neonatal care has improved, survival of extremely prematurely born neonates has increased significantly.
