Afrikaiak a világban, afrikaiak Magyarországon – Elhanyagolt diaszpóra?

open access: yesModern Geográfia, 2017
The paper gives a comprehensive geo-economic analysis of Europe, providing a new, distance-based definition of core (360 km), centre (720 km), semi-periphery (1440 km) and periphery (over 1440 km), which is also relevant for other, non-European economies.

Gospodarka oparta na wiedzy a globalne procesy geopolityczne

open access: yesPrace Komisji Geografii Przemysłu Polskiego Towarzystwa Geograficznego, 2010
Emergence of the knowledge-based economy coincides with the process of deindustrialization in the more wealthy countries. In some Asian countries, we can observe an intense process of industrialization.

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

open access: yesFEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

open access: yesFEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

Mature peripheral RPE cells have an intrinsic capacity to proliferate; a potential regulatory mechanism for age-related cell loss.

open access: yesPLoS ONE, 2011
BackgroundMammalian peripheral retinal pigmented epithelium (RPE) cells proliferate throughout life, while central cells are senescent. It is thought that some peripheral cells migrate centrally to correct age-related central RPE loss.Methodology ...

PARK(ing) time–How park deficiency affects the biological clock in a Drosophila model of Parkinson's disease

open access: yesFEBS Letters, EarlyView.
Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

open access: yesL'Espace Politique, 2009
The use of the term periphericity has been greatly in favour which is inversely proportional to the rigour of its definition. This observation, if periphicity is apprehended in a different perspective, takes us to consider and reconsider quite a number ...

Centre, Periphery and Back

open access: yesHistorein
This special issue consists of a collection of six articles by Greek historians of the periphery of Europe that look at the perplexities and challenges of European historiography of the centre. Their analysis aims to interpret pivotal moments that have shaped recent historiographies in tackling the advance of global history, and the successful or ...
