Parkinson's disease (PD) is a progressive neurological disorder caused by rather selective degeneration of the dopaminergic (DA) neurons in the substantia nigra. Though subject to intensive research, the etiology of this nigral neuronal loss is still enigmatic and treatment is basically symptomatic. The current major hypothesis suggests that nigral neuronal(More)
Dinucleotides (Np n N′; N and N′ are A, U, G, or C, n = 2–7) are naturally occurring physiologically active compounds. Despite the interest in dinucleotides, the composition of their complexes with metal ions as well as their conformations and species distribution in living systems are understudied. Therefore, we investigated a series of Mg2+ and Ca2+(More)
The effect of two impression materials used in three different techniques was tested for the accuracy of the marginal fit of metal castings. Sixty identically prepared Ivorine teeth were divided into groups of 20. The following methods were selected to make impressions: (1) putty in a metal stock tray with simultaneous elastomeric impression wash, (2)(More)
A method was described in Part I in which mandibular border movements of a subject can be compared with the movements generated by various articulators (fully adjustable Denar SE and semiadjustable Denar Mark II) by using an electronic pantograph, the Pantronic. The mean values of 12 sets of plots from this device were calculated and graphs were generated.(More)
