Review Essay: Does Qualitative Network Analysis Exist?

open access: yesForum: Qualitative Social Research, 2007
Social network analysis was formed and established in the 1970s as a way of analyzing systems of social relations. In this review the theoretical-methodological standpoint of social network analysis ("structural analysis") is introduced and the different

Peak bone mass after exposure to antenatal betamethasone and prematurity: Follow-up of a randomized controlled trial

open access: yes, 2006
Small birth size is associated with reduced adult bone mass. We determined if antenatal betamethasone exposure, birth weight, or prematurity affects peak bone mass in 174 adults. Antenatal betamethasone exposure did not.

Subtype‐specific enhancer RNAs define transcriptional regulators and prognosis in breast cancers

open access: yesMolecular Oncology, EarlyView.
This study employed machine learning methodologies to perform the subtype‐specific classification of RNA‐seq data sets, which are mapped on enhancers from TCGA‐derived breast cancer patients. Their integration with gene expression (referred to as ProxCReAM eRNAs) and chromatin accessibility profiles has the potential to identify lineage‐specific and ...

The Performativity of Qualitative Social Research

open access: yesForum: Qualitative Social Research, 2011
Within the last two decades qualitative social research has established itself in most, if not all, of the social sciences. But this emergence has proceeded very differently in institutional and in socio-cognitive aspects.

Penerapan Model Pembelajaran ROAR (Read, Observe, Auditory, Review) Meningkatkan Pemahaman Konsep Siswa

open access: yesIndonesian Journal of Learning Education and Counseling, 2019
The ROAR learning model is learning that gives students the broadest opportunity to develop concepts, pre-existing ideas become new concepts. The concept is built through direct observation because during learning the teacher presents examples of reality

Bone geometry and volumetric bone mineral density in girls with Turner syndrome of different pubertal stages

open access: yes, 2010
Objective An increased rate of fractures has been reported in patients with Turner syndrome (TS). We aimed to assess bone geometry and volumetric bone mineral density (vBMD) at the radius in girls with TS and to evaluate the relationships between bone

Endothelialized tissue engineered 3D-construct for bone repair [PDF]

open access: yes, 2005
One of the main problems arising when implanting a graft into a large bone gap is its insufficient vascularization in the central region. This results in impaired bone healing and often leads to necrosis in the graft.

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells

open access: yesMolecular Oncology, EarlyView.
This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

open access: yesMolecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated
