Growth induced instabilities in a circular hyperelastic plate [PDF]
arXiv, 2021 In this work, we have explored growth-induced mechanical instability in an isotropic circular hyperelastic plate. Consistent two-dimensional governing equations for a plate under a general finite strain are derived using a variational approach. The derived plate equations are solved using the compound matrix method for two cases of axisymmetric growth ...

Identification of functional VEGF receptors on human platelets [PDF]
, 2002 Platelets secrete platelet-derived growth factor (PDGF) and vascular endothelial growth factor (VEGF) upon stimulation. We have demonstrated that platelets have functionally active PDGF α-receptors, a transmembrane tyrosine kinase involved in negative ...

Nonlinear Evolution of Very Small Scale Cosmological Baryon Perturbations at Recombination [PDF]
Astrophys.J. 547 (2001) 1-11, 2000 The evolution of baryon density perturbations on very small scales is investigated. In particular, the nonlinear growth induced by the radiation drag force from the shear velocity field on larger scales during the recombination epoch, which is originally proposed by Shaviv in 1998, is studied in detail.

Sorafenib prevents human retinal pigment epithelium cells from light-induced overexpression of VEGF, PDGF and PlGF [PDF]
, 2010 Background Cumulative light exposure is significantly associated with progression of age-related macular degeneration (AMD). Inhibition of vascular endothelial growth factor is the main target of current antiangiogenic treatment strategies in AMD ...

Platelet-Derived Growth Factor C in Alcoholics
Alcohol and Alcoholism, 2020 Abstract Aims Platelet-derived growth factor (PDGF) promotes liver collagen deposition, acting on hepatic stellate cells. Despite this, low serum PDGF levels were reported in chronic hepatitis C or B infection, although some studies yield the opposite result.

Influence of the growth gradient on surface wrinkling and pattern transition in growing tubular tissues [PDF]
, 2021 Growth-induced pattern formations in curved film-substrate structures have attracted extensive attentions recently. In most existing literature, the growth tensor is assumed to be homogeneous or piecewise homogeneous. In this paper, we aim at clarifying the influence of a growth gradient on pattern formation and pattern evolution in bilayered tubular ...

Selective Desensitization of Growth Factor Signaling by Cell Adhesion to Fibronectin [PDF]
, 2007 Cell adhesion to the extracellular matrix is required to execute growth factor (GF)-mediated cell behaviors, such as proliferation. A major underlying mechanism is that cell adhesion enhances GF-mediated intracellular signals, such as extracellular ...
