From activity to learning: using cultural historical activity theory to model school library programmes and practices

open access: yesInformation Research: An International Electronic Journal, 2007
Introduction. changes in educational policy and practice demand that we examine school library programmes from a new perspective. As a model that takes a developmental view of minds in context, Cultural Historical Activity Theory is particularly well ...

Identification of functional murine mitochondrial formyl peptides and their effects on myeloid‐derived suppressor cell generation

open access: yesFEBS Open Bio, EarlyView.
We first identified functional murine mitochondrial N‐formyl peptides (MT‐FPs) and investigated their effects on the in vitro myeloid‐derived suppressor cell (MDSC) generation from bone marrow cells. We demonstrated that MT‐FPs acted directly on bone marrow cells to promote MDSC generation and modulated the polymorphonuclear (PMN)‐MDSC/monocyte (M ...

Exon 7 splicing of ERα predicts poor prognosis and increases phenotypic heterogeneity in luminal a subtype breast cancer

open access: yesFEBS Open Bio, EarlyView.
ERα splice variant ERα∆7 lacks the C‐terminus, and its expression may change phenotypes of breast cancers. Our results showed that ERα∆7 is found in the luminal A subtype, and elevated ERα∆7 levels are linked to improved cell survival with lower proliferation and migration.

Establishing an assay to evaluate d‐amino acid oxidase enzyme kinetics and inhibition using WST‐8 redox dye

open access: yesFEBS Open Bio, EarlyView.
This study investigated a novel WST‐8‐based assay for evaluating d‐Amino acid oxidase (DAO) inhibitors. We confirmed its effectiveness using known inhibitors and found that uremic toxins possess relatively weak inhibitory activity compared to existing drugs.

HUMAN NATURE OR HUMANITY: BETWEEN GENES AND VALUES [PDF]

open access: yes, 2012
We are within nature and culture, conditioned simultaneously by genes and meanings. This form of our self-understanding is the result of fundamental modifications that happened in modern philosophical anthropology and of the impact of the natural Science.

Matrix metalloproteinase‐9 regulates cell adhesion and membrane protrusive activity of ovarian cancer cells

open access: yesFEBS Open Bio, EarlyView.
Matrix metalloproteinase‐9 (MMP9) drives ovarian cancer progression. Using MMP9‐null cells (M9‐KO) created from ovarian cancer cells, we found MMP9 loss did not block Epidermal Growth Factor (EGF)‐driven E‐cadherin dissolution or EMT but delayed and reduced EGF‐driven membrane protrusions. Transient MMP9 re‐expression drove membrane protrusion.

EDUCAÇÃO EM CIÊNCIAS E A TEORIA DA ATIVIDADE CULTURAL-HISTÓRICA: CONTRIBUIÇÕES PARA A REFLEXÃO SOBRE TENSÕES NA PRÁTICA EDUCATIVA

open access: yesEnsaio Pesquisa em Educação em Ciências, 2014
Activity Theory has its origins in the works by Vygotsky and currently spans diverse fields of knowledge. Recently, much of Science Education research have used Socio-Cultural-Historical references, however their potential use is far from being achieved.

In Search of a Singular I: A Structurational Analysis of Passing [PDF]

open access: yes, 2005
It is easy to envision the socio-cultural phenomenon of passing as a relic of a bygone era, yet passing is markedly more. From a historical perspective, passing-as-white is a strategy of representation through which light-skinned, white-looking ...

Iron homeostasis disruption and lipid peroxidation in skeletal muscle during short‐term immobilization

open access: yesFEBS Open Bio, EarlyView.
14‐day casting‐induced immobilization reduced gastrocnemius muscle mass and increased non‐heme iron and ferritin heavy chain levels. Despite iron accumulation, transferrin receptor 1 and iron regulatory protein 2 were paradoxically upregulated. Lipid peroxidation was elevated without compensatory antioxidant responses.

Canadian Contributions to Social Reproduction Feminism, Race and Embodied Labor [PDF]

open access: yes, 2008
Recent methodological advances in Canadian Social Reproduction Feminism foreground labor as a foundational concept of social theory and, as a result, address the structuralist bias critics of the paradigm have identified, while still grounding theory in ...
