Summary
Parkinson
Area of Science:
- Neuroscience
- Materials Science
- Biochemistry
Background:
- Parkinson's disease is a neurodegenerative disorder.
- The substantia nigra is a key brain region affected in Parkinson's disease.
- The role of mineral deposits in Parkinson's disease pathogenesis is not fully understood.
Purpose of the Study:
- To investigate the presence and nature of crystalline deposits in the substantia nigra of Parkinson's disease patients.
- To identify potential precursors and origins of these crystalline structures.
Main Methods:
- Electron-beam exposure of substantia nigra tissue extracts.
- Crystallographic analysis of detected mineral deposits.
Main Results:
- Titanium dioxide (TiO2) and calcium oxide (CaO) crystals were identified in Parkinson's disease substantia nigra specimens.
- Calcium oxalate dihydrate was proposed as a precursor to CaO crystals.
- Hydrated iron oxide crystals were also detected.
Conclusions:
- Crystalline deposits, including TiO2, CaO, and hydrated iron oxide, are present in the substantia nigra of Parkinson's disease donors.
- Calcium oxalate may be a precursor to CaO crystal formation.
- These findings suggest potential roles for mineral deposition in Parkinson's disease pathology.

16.9K
Ionic crystals consist of two or more different kinds of ions that usually have different sizes. The packing of these ions into a crystal structure is more complex than the packing of metal atoms that are the same size.
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...

01:25Crystal Growth: Principles of Crystallization
4.9K
Crystallization is a phase transformation process in which crystals are precipitated from a supersaturated solution or formed from other sources. During crystallization, atoms or molecules arrange themselves into a well-defined, rigid crystal lattice to minimize energy.
Initiating crystallization involves manipulating the concentration of the solute and the temperature of the solution. Since crystal growth occurs when the ratio of concentration and solubility of the solute in the solvent...

Crystal Field Theory
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.

Tetrahedral Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...

21.6K
Imagine adding a small amount of sugar to a glass of water, stirring until all the sugar has dissolved, and then adding a bit more. You can repeat this process until the sugar concentration of the solution reaches its natural limit, a limit determined primarily by the relative strengths of the solute-solute, solute-solvent, and solvent-solvent attractive forces. You can be certain that you have reached this limit because, no matter how long you stir the solution, undissolved sugar remains. The...

In the macroscopic world, objects that are large enough to be seen by the naked eye follow the rules of classical physics. A billiard ball moving on a table will behave like a particle; it will continue traveling in a straight line unless it collides with another ball, or it is acted on by some other force, such as friction. The ball has a well-defined position and velocity or well-defined momentum, p = mv, which is defined by mass m and velocity v at any given moment. This is the typical...
