Growth factors of random butterfly matrices and the stability of avoiding pivoting [PDF]

open access: yesSIAM Journal on Matrix Analysis and Applications, Volume 44, Issue 3 (2023), 2022
Random butterfly matrices were introduced by Parker in 1995 to remove the need for pivoting when using Gaussian elimination. The growing applications of butterfly matrices have often eclipsed the mathematical understanding of how or why butterfly matrices are able to accomplish these given tasks.

An FGFR/AKT/SOX2 Signaling Axis Controls Pancreatic Cancer Stemness

open access: yesFrontiers in Cell and Developmental Biology, 2020
Cancer stemness is associated with high malignancy and low differentiation, as well as therapeutic resistance of tumors including pancreatic ductal adenocarcinoma (PDAC). Fibroblast growth factors (FGFs) exert pleiotropic effects on a variety of cellular

Growth factors of orthogonal matrices and local behavior of Gaussian elimination with partial and complete pivoting [PDF]

open access: yesSIAM Journal on Matrix Analysis and Applications, Volume 45, Issue 3 (2024), 2023
Gaussian elimination (GE) is the most used dense linear solver. Error analysis of GE with selected pivoting strategies on well-conditioned systems can focus on studying the behavior of growth factors. Although exponential growth is possible with GE with partial pivoting (GEPP), growth tends to stay much smaller in practice.

Glucagon-like peptide 1 and glucose-dependent insulinotropic peptide hormones and novel receptor agonists protect synapses in Alzheimer’s and Parkinson’s diseases

open access: yesFrontiers in Synaptic Neuroscience, 2022
Glucagon-like peptide 1 (GLP-1) and glucose-dependent insulinotropic peptide (GIP) are peptide hormones and growth factors. A major pathological feature of both Alzheimer’s dis-ease (AD) and Parkinson’s disease (PD) is the loss of synaptic transmission ...

Growth factor for therapeutic angiogenesis in ischemic heart disease: A meta-analysis of randomized controlled trials

open access: yesFrontiers in Cell and Developmental Biology, 2022
Aim: This study was designed to systematically evaluate the effects of growth factor (GF) for therapeutic angiogenesis on ischemic heart disease (IHD) by pooling the results of randomized controlled trials (RCTs).Methods and Results: PubMed, EMBASE, and ...

Synergistic growth factor microenvironments [PDF]

open access: yes, 2016
Growth factors (GF) are remarkably powerful signalling molecules that orchestrate developmental biology. GFs are currently used in medjcal applications with limited success but it is clear that if their potential can be harnessed for biomedicine then ...

Advances in wound repair and regeneration: Systematic comparison of cell free fat extract and platelet rich plasma

open access: yesFrontiers in Chemistry, 2022
Background: Previous studies showed Cell free fat extract (CEFFE) and Platelet rich plasma (PRP) could effectively accelerate wound healing. However, the comparative study on curative effect is still lacking.

Emerging roles of growth factors in osteonecrosis of the femoral head

open access: yesFrontiers in Genetics, 2022
Osteonecrosis of the femoral head (ONFH) is a potentially disabling orthopedic condition that requires total hip arthroplasty in most late-stage cases. However, mechanisms underlying the development of ONFH remain unknown, and the therapeutic strategies ...

Effect on the canine Eck fistula liver of intraportal TGF‐β alone or with hepatic growth factors [PDF]

open access: yes, 1992
Transforming growth factor‐β canceled the hepatocyte proliferation caused by transforming growth factor‐α when the two substances were mixed and administered through a disconnected central portal vein branch after creation of an Eck fistula. In contrast,

Growth and Growth Factors [PDF]

open access: yes, 2008
The last year has again seen some major advances in the Growth and Growth Factors field. Significant advances have been made in our understanding of the genetics of growth. For example, mutations in the pericentrin gene PCNT are associated with both primordial dwarfism and Seckel syndrome.
