High spin states in ^174Re have been investigated via the ^152Sm (^27 Al, 5nγ) ^174Re reaction. Gamma-ray excitation functions, x-γ and γ-γ coincidences have been measured.

Gamma-ray excitation functions, x-γ and γ-γ coincidences have been measured. Two rotational bands built on the πh9/2 × vi13/2 and πh11/2 × vi13/2 configurations have been identified and extended up to high-spin states. The relative spin and parity of the band levels have been unambiguously fixed due to observations of several inter-band transitions. Both the bands show the low-spin signature inversion, which is consistent with systematic expectations for the high-j two-quasiparticle bands in the A = 170 mass region. 展开更多

We herein report the case of a 46 year old man with chronic inflammatory demye linating polyneuropathy (CIDP)-with hyperIgEaemia. The patient presented with b ilateral weakness, generalized hyporeflexia, and mild paresthesia of the fingers of both hands. Nerve conduction studies revealed multiple sites of motor conduc tion block inthe absence of sensory abnormalities. Muscle strength increased, as did compound muscle action potential (CMAP)-amplitude immediately after the in travenous infusion of immunoglobulin (IVIg). Serum IgE levels also fluctuated in parallel with his relapsing-remitting clinical course. We propose that pure mo tor CIDP may be immune mediated and suggest that IgE-mediated allergy may be on e potential cause of this condition. 展开更多
