A growing body of evidence suggests pesticides may play a role in Parkinson’s disease (PD) in humans. Self­reported PD has been associ­ ated with lifetime use of pesticides, and animal studies have suggested that the pesticides paraquat and rotenone can cause oxidative stress and mitochondrial dysfunction, respectively—posited mechanisms of action in PD—as well as symptoms in rodents similar to...

The cell cycle usually refers to the mitotic cycle, but the cell-division cycle in the plant kingdom consists of not only nuclear but also mitochondrial and chloroplast division cycle. However, an integrated control system that initiates division of the three organelles has not been found. We report that a novel C-terminal kinesin-like protein, three-organelle division-inducing protein (TOP), c...

In the title complex, [PdBr(2)(C(12)H(8)N(2))], the Pd(II) ion is four-coordinated in a slightly distorted square-planar environment by two N atoms of the chelating 1,10-phenanthroline ligand and two bromide ions. The complex displays numerous inter-molecular π-π inter-actions between adjacent six-membered rings, the shortest centroid-centroid distance being 3.680 (4) Å. The nearly planar [maxi...

1,8-Dihydroxy-2-(imidazol-2-ylazo)-naphthalene-3,6-disulphonic acid (imidazol-azo-chromotropic acid IACA) was immobilized onto the anion exchange resin Dowex 1-X8, 50-100 mesh. The aim of this work was to investigate the mechanism of the complex formation between Pd(II) and immobilized IACA by following the absorption spectra of the solid phase. The reaction between Pd(II) and immobilized azo-d...

Parkinson's Disease (PD) has traditionally been viewed as primarily a disturbance of motor functioning, typically involving tremor, rigidity, hypokinesia, gait disturbance, and postural instability. More recently, decline in cognitive function has been recognized as a feature of PD. One prominent cognitive symptom of PD involves deficits on tasks of spatial ability. However, findings of visual-...

The title compound, [Pd(CH(4)N(2)S)(4)](SCN)(2), consists of complex [Pd(TU)(4)](2+) [TU = thio-urea, SC(NH(2))(2)] cations and thio-cyanate counter-anions. The Pd(II) cation is situated on an inversion centre and exhibits an almost square-planar coordination by the S atoms of the TU ligands. The complex cations are connected through the thio-cyanate ions via N-H⋯N [2.922 (3)-3.056 (3) Å] and N...

The title compound, [Pd(C(14)H(15)N(2))(2)], is a square-planar palladium complex composed of two deprotonated pyrrole-2-carbaldimine ligands coordinating a central Pd(II) atom. In the crystal, three crystallographically independent complex mol-ecules are observed, one of which is located in a general position, whereas the Pd(II) atoms of the other mol-ecules are situated on crystallographic in...

In patients with Parkinson's disease (PD), the associated pathology follows a characteristic pattern involving inter alia the enteric nervous system (ENS), the dorsal motor nucleus of the vagus (DMV), the intermediolateral nucleus of the spinal cord and the substantia nigra, providing the basis for the neuropathological staging of the disease. Here we report that intragastrically administered r...

Palladium complexes containing 2,7-bis(mesitylimidazolylidenyl)naphthyridine (NHC-NP) have been synthesized and characterized. Reaction of [{Ag(3)(NHC-NP)(2)}(PF(6))(3)] with [Pd(PhCN)(2)Cl(2)] provided an unusual dipalladium complex bridged by two NHC-NP units, forming a 20-membered dinuclear metallacycle [{Pd(2)(NHC-NP)(2)Cl(2)}(PF(6))] (2) in high yield. Treatment of 2 with KI in acetone yie...
