Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

National Assessment of Vocational Education

open access: yes, 2005
The National Assessment of Vocational Education (NAVE) is a congressionally-mandated evaluation of the 1998 Carl D. Perkins Vocational and Technical Education Act and of the implementation and outcomes of vocational education in the United States.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Assessment in senior outdoor education: A catalyst for change?

open access: yes, 2011
In recent times issues of sustainability and place, and human connectedness and care for outdoor environments, have been the subject of increasing professional dialogue in outdoor education in Aotearoa New Zealand. Attention has been drawn to the ways in

Formative computer-based assessment in higher education

open access: yes, 2009
A formative computer-based assessment (CBA) was one of three instruments used for assessment in a Bachelor of Education course at Queen's University (Ontario, Canada) with an enrolment of approximately 700 students.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

open access: yesFEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Critical assessment issues in work-integrated learning

open access: yes, 2014
Assessment has long been a contentious issue in work-integrated learning (WIL) and cooperative education. Despite assessment being central to the integrity and accountability of a university and long-standing theories around best practice in assessment ...

How convincing is alternative assessment for use in higher education?

open access: yes, 2004
The current preference for alternative assessment has been partly stimulated by recent evidence on learning which points to the importance of students' active engagement in the learning process.

Assessments in Education

open access: yes, 2023
Assessments like standardized tests and teacher evaluations are central elements of educational systems. Assessments affect the behaviour of students, teachers, parents, schools, and policymakers through at least two channels: The information channel and the incentive channel.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...
