Migration as cause and consequence of aspirations : DEMIG project paper no. 13 [PDF]

open access: yes, 2012
This paper aims to disentangle the relationship between aspirations and migration by analysing why Indonesian internal migrants generally have higher aspirations when compared with non-migrants.

Restoration of m6A‐Modified circPSMB1 Suppresses Chordoma Progression and Enables Local Nanotherapeutic Intervention

open access: yesAdvanced Science, EarlyView.
An m6A‐modified circRNA, circPSMB1, is identified as a tumor suppressor in chordoma. METTL3‐dependent m6A promotes circPSMB1 interaction with HNRNPA2B1, limiting c‐MYC expression and malignant progression. An injectable HMnO2‐based nanohydrogel enables local circPSMB1 delivery and tumor microenvironment‐responsive therapy, offering a promising strategy

Far from happiness: the impact of children’s migration distance on parents’ mental health

open access: yesHumanities & Social Sciences Communications
The mental well-being of middle-aged and elderly individuals is significantly impacted by the migration patterns of their offspring. Utilizing three-wave panel data from the China Health and Retirement Longitudinal Study (CHARLS) across 13,432 households,

A Huaxian Formula Nanoformulation Confers Protection Against Acute Radiation‐Induced Lung Injury by Targeting Ferroptosis

open access: yesAdvanced Science, EarlyView.
An inhalable, nanoengineered herbal therapy achieves protection against acute radiation‐induced lung injury via self‐assembled nanomicelle‐mediated pulmonary targeting and a previously unrecognized dual mechanism that attenuates oxidative stress while inhibiting ferroptosis in alveolar epithelial cells.

Glucose and Glutamine Deprivation Promotes Breast Cancer Lung Metastasis via BRD4‐Dependent Enhancer Activation

open access: yesAdvanced Science, EarlyView.
To model a nutrient‐restricted tumor microenvironment, breast cancer cells were adapted to low glucose and glutamine levels. In the adapted cells, BRD4‐driven enhancer activation increases pro‐invasive EDN1 expression, facilitated by ATF3/c‐JUN and reinforced by enhancer RNA.

North African migration systems: evolution, transformations and development linkages

open access: yes, 2007
The main aim of this paper is to understand the evolution and transformation of North African migration systems since 1945 within a conceptual framework drawing on migration systems and transitional migration theory.

Contextualizing immigrant interwave dynamics and the consequences for migration processes: Ukranians in the United Kingdom and the Netherlands [PDF]

open access: yes, 2011
What drives international migration? Theories of migration networks, migration culture, migration systems and cumulative causation suggest that once a critical threshold level of migrants have settled, migration tends to stimulate the creation of social ...

Distinct Cleavage Trajectories Mediated by DNA and RNA Substrate in Argonaute From Methanocaldococcus Fervens

open access: yesAdvanced Science, EarlyView.
This study characterizes MfAgo, an enzyme exhibiting highly efficient DNA‐guided DNA and RNA cleavage capability. Precise RNA cleavage strictly requires dimerization to stabilize the PIWI‐loop region, while its robust DNA cleavage functions in a dimerization‐independent manner.
