Functional impact of the hyperpolarization-activated current on the excitability of myelinated A-type vagal afferent neurons in the rat.

1. The hyperpolarization-induced, cation-selective current I(h) is widely observed in peripheral sensory neurons of the vagal and dorsal root ganglia, but the peak magnitude and voltage- and time-dependent properties of this current vary widely across afferent fibre type. 2.

Hepatic angiomyolipoma: a clinical experience in diagnosis and treatment.

Background: Hepatic angiomyolipoma is a rare mesenchyme-derived neoplasm often misdiagnosed as hepatocellular carcinoma, and the treatment for it remains controversial.

Aims: To develop the optimal preoperative diagnoses means and treatment modalities of hepatic angiomyolipoma.

Methods: Retrospective analysis of the clinical features, treatment, and prognostic data of 17 hepatic AML patients admitted to Chinese People's Liberation Army Generation Hospital between 1996 and 2006.
