New epistemological foundations for cultural psychology: from an atomistic to a self-organizing view of living systems

open access: yesAnnali dell'Istituto Superiore di Sanità, 2014
An epistemological foundation for cultural psychology is essential to neuro- and behavioural sciences for the challenge psychological sciences must currently face: searching for an explanation of how a brain can become a mind and how individuals assign a

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Modelling stem cell differentiation related processes—A practical overview for biologists

open access: yesFEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

ESTIMATING CALORIC EXPENDITURE USING THE PHYSICAL ACTIVITY INDEX (PAI) IN CHILDREN AND ADOLESCENTS PERFORMING A MULTISTAGE MAXIMAL EXERCISE TEST [PDF]

open access: yes, 2014
PURPOSE: The primary purposes of this investigation were (a) to examine the validity of the PAI, (b) to develop a statistical model to predict cumulative Kcal expenditure using PAI as the predictor variable and (c) to develop a statistical model to ...

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Repercussões cardíacas após infarto do miocárdio em ratas submetidas previamente a exercício físico Cardiac implications after myocardial infarction in rats previously undergoing physical exercise

open access: yesArquivos Brasileiros de Cardiologia, 2013
FUNDAMENTO: Poucos estudos analisaram os efeitos cardíacos do exercício físico prévio à oclusão coronariana. OBJETIVO: Avaliar, em ratas submetidas a exercício físico, as repercussões do infarto do miocárdio.

Decoding the dynamic extracellular matrix in cancer—3D models and bioscaffolds rewire the rules of tumor progression

open access: yesFEBS Letters, EarlyView.
Cancer progression is regulated by the dynamic matrix code of the tumor microenvironment, which influences cellular behavior and disease development. Importantly, matrix remodeling in three‐dimensional cancer models more accurately reflects in vivo conditions compared to conventional two‐dimensional systems.
