Replication Data for: A global panel dataset of dyadic dual citizenship acceptance
No full textDual citizenship provides access to secure legal status and rights in more than one country for an unprecedented number of migrants and their descendants around the world. While this requires the matching of legal regulations between two states, existing studies of dual citizenship typically focus on either migrant origin or destination perspectives. To explore the dyadic nature of this phenomenon we introduce the GLOBALCIT Dyadic Dual Citizenship Acceptance Dataset, covering over 1.8 million directed dyad-year observations measuring the legal rules in place in up to 201 states back to 1960. We identify regulatory trends and present estimates of the number and proportion of global migrants affected by changing policy constellations, as well as variation in acceptance across political regimes. We show that migrants are more likely to acquire destination country citizenship, and thus achieve democratic representation, in constellations where they can maintain a legal link with their origin country.
The GcDDCAD is made available freely for non-commercial use by the general public. Data are not intended to be used for determining citizenship status in individual cases, for which it is recommended to seek professional legal advice.

Magnesium transport across the blood-brain barriers
No full textThe finding that magnesium levels are reduced in acute and chronic brain diseases has led to a recent surge in interest in the role of magnesium in the normal and injured nervous system, although the mechanisms of magnesium decline in pathological conditions and its availability in the neural tissue after administration are not fully understood. The brain has two main barrier systems: (1) the blood-‐brain barrier (BBB) formed by brain capillary endothelial cells which separate the blood from the extracellular fluid in the neuropil; and (2) the blood-‐CSF barrier (BCSFB) formed by choroidal epithelial cells which separate the blood from the CSF. Genetic studies in families with hereditary hypomagnesemia have identified mutations in two genes encoding claudin-‐16 (paracellin-‐1) and claudin-‐19, both localized at tight junctions between nephron epithelial cells and providing passive paracellular conductance for magnesium in the kidney. Endothelial cells of the BBB also express claudins, although whether members of the claudin family expressed at the BBB and BCSFB have similar conductance for magnesium akin to the role of claudin-‐16 and -‐19 in the nephron remains to be confirmed. Recently, the transient receptor potential melastatin (TRPM) members TRPM6 and TRPM7 have been identified as cation channels for magnesium transport. Although it is not known if choroidal epithelial cells express TRPM6 and TRPM7, these molecules are expressed by brain endothelial cells and may play a role in magnesium transport. While it is evident that magnesium enters the CNS through the BBB and is actively transported by choroidal epithelial cells into the CSF, the mechanisms of its entry into the brain will require further investigation.Mounir N.

Magnesium and stress
No full textMagnesium status is highly associated with stress levels, with both stress and hypomagnesemia potentiating each other’s negative effects. Indeed, hypomagnesemia has been associated with stressful conditions such as photosensitive headache, fibromyalgia, chronic fatigue syndrome, audiogenic stress, cold stress, and physical stress, amongst others. The role of magnesium in these conditions is unclear, although a number of potential mechanisms for magnesium’s action have been identified including via the glutamatergic, serotonergic, and adrenergic neurotransmitter systems, as well as via several neuro-‐ hormones. The current review examines the link between magnesium deficiency and stress, focusing on the association between magnesium and various stress pathologies, magnesium’s potential interaction with stress pathways, and magnesium’s effects on the brain.Magdalena D.
