The effect of doping a molecular spin ladder with non-magnetic impurities.

Since carrier doping of two-leg spin ladders can theoretically induce a superconductive state, investigation of such systems is of great use in the study of superconductivity. In this paper, we report the successful creation of a non-magnetic impurity doped into a two-leg molecular spin ladder and the characterization of its magnetic properties.

Cognitive dysfunction in a patient with brainstem hemorrhage.

A 54-year-old, right-handed male suffered sudden onset of vertigo and vomiting. He was diagnosed with brainstem hemorrhage, and treatment was administered. After the vertigo improved, he showed disturbance of attention and anterograde amnesia.

[De novo aneurysm after ten days from the onset of SAH].

A 56-year-old man presented with severe headache. Neurological examinations found no abnormalities and no disturbance of consciousness. CT revealed a subarachnoid hemorrhage.

Prognostic implication of p27 expression in primary central nervous system lymphoma.

To clarify the role of p27/Kip1 (p27) in primary central nervous system lymphomas (PCNSLs), we examined p27 expression by immunohistochemical methods in a series of 22 patients with PCNSL. We attempted to correlate the expression of p27 with proliferation potential and prognosis. Although the MIB-1 labeling index (LI) was lower in tumors with low p27 expression (26.
