Parkinson’s disease (PD) is a major cause of morbidity and mortality among older individuals. Several researchers have suggested that iron chelators which cross the blood-brain barrier (BBB) might have clinical efficacy in treating PD. Therefore, efforts are made not only in order to improve the effect of L-dopa but also to introduce drugs which…[Lees meer]

After several decades studying different acto-myosin complexes at lower and intermediate resolution – limited by the electron microscope instrumentation available then – recent advances in imaging technology have been crucial for obtaining a number of excellent high-resolution 3D reconstructions from cryo electron microscopy. The resolution level…[Lees meer]

Two new halogen-rich ortho-borates, Ba6BO3Cl9 and Pb6BO4Cl7, were synthesized and characterized. Interestingly, Pb6BO4Cl7 contains rare uncondensed BO4 tetrahedra. The structure analyses indicate that the large cation/boron ratio, the stereochemically active lone pairs on Pb2+ cations and the rich Cl- anions play key roles in the formation of the…[Lees meer]

A maximum of 2/4 bristle rows were in contact with the tooth surfaces; in some areas, the bristles had no contact to the teeth. Conclusions Uninstructed manual toothbrushing is superior to auto-cleaning. The alignment and density of the auto-cleaning device’s bristle rows need to be improved, and assorted sizes would be necessary to cover…[Lees meer]

ng to their vital signs, clinical symptoms, laboratory tests and imaging changes. Patients should receive effective psychological counselling.Background To investigate the prognostic value of lymph node ratio (LNR), as well as the correlation with docetaxel, cisplatin, and 5-FU (TPF) induction chemotherapy, in patients with locally advanced oral…[Lees meer]

Herein, the absorption and oxidation reactions of SO2 on TiO2 nanoparticles (TiO2 NPs) at 296 K under various environmental conditions (humidity, UV irradiation, and ozone copresence) were investigated by using a flow chamber reaction system, synchrotron X-ray absorption near-edge structure (XANES) and high resolution synchrotron X-ray…[Lees meer]
