production of reactive oxygen species (ROS) and their removal, has been implicated in the progression of many neurodegenerative diseases including Alzheimer’s disease (AD) and stroke. Inflammation is characteristic of brain tissue, pathologically affected by neurological diseases such as AD and Parkinson’s disease. Cognitive deficits due to aging and AD are related to the increased vulnerabilit...

Superkonduktor fasa (Tl0.5Pb0.5)Sr2Ca(Cu2-xCrx)O7-δ (Tl-1212) bagi x = 0 hingga 0.100 telah disediakan menggunakan kaedah tindak balas keadaan pepejal. Tujuan kajian ini ialah menentukan suhu optimum untuk pembentukan Tl-1212 dengan komposisi ini. Sampel dalam aliran gas oksigen tiga berlainan iaitu 850 °C kerajang perak selama 5 jam, dan 950 1000 4 min. Bahan diciri pembelauan sinar-X mengenal...

We have performed a detailed study of the conductance characteristics obtained by point contact junctions realized between a normal Pt/Ir tip and syntered RuSr 2 GdCu 2 O 8 (Ru-1212) samples. Indeed, this compound is subject of great interest due to the coexistence of both magnetic order and bulk superconductivity. In our experiments, the low temperature tunneling spectra reproducibly show a ze...

We use a notion (introduced in Topology 41 (2002), 1119–1212), which is stronger than the concept of filtration pair, to prove a stable/unstable manifold general theorem for local homeomorphisms of the plane in a neighborhood of an isolated fixed point.

BACKGROUND There is a difference in the location of colorectal mucosal lesions and invasive cancers. AIMS To ascertain whether the location of colorectal neoplasms reflects the carcinogenesis pathway. METHODS The subject material consisted of 4147 neoplastic lesions that had been resected endoscopically or surgically from 5025 patients. Mucosal lesions and submucosal cancers were classified...
