Q: Passage: Blood–brain barrier -- The blood-brain barrier may become leaky in select neurological diseases, such as amyotrophic lateral sclerosis, epilepsy, brain trauma and edema, and in systemic diseases, such as liver failure. The blood--brain barrier becomes more permeable during inflammation, allowing antibiotics and phagocytes to move across the BBB. However, this also allows bacteria and viruses to infiltrate the blood-brain barrier. Examples of pathogens that can traverse the blood-brain barrier include toxoplasma gondii which causes toxoplasmosis, spirochetes like Borrelia (Lyme disease), Group B streptococci which causes meningitis in newborns, and Treponema pallidum which causes syphilis. Some of these harmful bacteria gain access by releasing cytotoxins like pneumolysin which have a direct toxic effect on brain microvascular endothelium and tight junctions.

Q: Passage: German nationality law -- German nationality law is the law governing the acquisition, transmission and loss of German citizenship. The law is based on a mixture of the principles of jus sanguinis and jus soli. In other words, one usually acquires German citizenship if a parent is a German citizen, irrespective of place of birth, or by birth in Germany to parents with foreign nationality if certain requirements are fulfilled. Naturalisation is also possible for foreign nationals after six to eight years of legal residence in Germany. However, non-EU and non-Swiss citizens must usually renounce their old citizenship before being naturalised in Germany. Citizens of other EU countries and of Switzerland usually can keep their old citizenship. Some EU countries do not allow dual citizenship even with other EU countries. German citizens wanting to acquire a non-EU or non-Swiss citizenship and to maintain their German citizenship must apply for a permission (Beibehaltungsgenehmigung) before acquiring the other citizenship, or they will automatically lose their German citizenship when they acquire the foreign citizenship. For details, see section ``Dual citizenship.''
