Encephalotoxin produced by activated mononuclear phagocytes is present in individuals having neurological disease including neurodegenerative and neuro-inflammatory diseases, such as Azlheimer’s disease, HIV-1-associated dementia, Creutzfeld-Jakob disease, Mild Cognitive Impairment, prion disease, mild congnitivemotor dysfunction, acute stroke, acute trauma, or neuro-AIDS. First and second leg portions continuously, smoothly, and uninterruptedly extend from the concave portion, with a single continuous and uninterrupted taper having a continuously increasing taper rate, to spaced-apart leg ends. The thermal protection circuits may disable the power supply voltage when the temperature of the connector exceeds a threshold value. Each pair of test pads connected to one of the subset of the nested serpentine lines has at least a respectively different turn section portion connected therebetween. The package comprises a polymeric film wrap, the film wrap comprising a laminate with an inner layer of a first polymer and an outer layer of a second polymer, and a surface bearing scoring along a path defining a substantially closed shape, the scoring at least partially penetrating the outer layer and not entirely penetrating the inner layer.
