Planning strategies for robust carbon-ion scanning radiotherapy for stage I esophageal cancer: a retrospective study.

This study aimed to establish a treatment planning strategy with carbon-ion scanning radiotherapy (CIRTs) for stage I esophageal cancer. The clinical data of seven patients treated with CIRTs were used. The setup error and interfractional and intrafractional motion error were analyzed using in-room computed tomography (CT) images for each treatment day.

Embryonic development of Carabus insulicola (Insecta, Coleoptera, Carabidae) with special reference to external morphology and tangible evidence for the subcoxal theory.

The egg morphology and successive changes in the developing embryos of the carabid ground beetle Carabus insulicola (Carabidae) are described based on light and scanning electron microscopy observations. Newly laid eggs of this species are ellipsoid and measure approximately 6.1 × 2.

Characterization of oxides obtained by heating a mixture of peroxoniobic acid and peroxotitanic acid.

Nb-doped TiO(2) particles were prepared by heating a mixture of peroxotitanic acid and peroxoniobic acid in air. When the heating temperature was more than 1173 K, the dominant phase obtained was rutile TiO(2), along with a small amount of TiNb(2)O(7). The relationship between the lattice parameters of the obtained rutile TiO(2) depended on the molar fraction of Nb/(Ti + Nb).

Ion channels permeable to monovalent and divalent cations: a single-file two-site channel model.

A cation channel from Tetrahymena cilia is permeable to both monovalent and divalent cations. A single-file two-site channel model was introduced for explaining the single channel currents of the channel in mixed solutions of K(+) and Ca(2+). In the model it was assumed that two potassium ions or one calcium ion can bind to the binding sites, and that the potassium ions between the binding sites are in a fast equilibrium condition.

Lower cervical origin of the P13-like potential in median SSEPS.

The authors studied the origin of the scalp P13-like potential in median somatosensory evoked potentials, which have been reported to be preserved in patients with cervicomedullary lesions or in brain death. There were five patients with high to middle cervical lesions (C2/3 or C3/4 level). Small P13-like potentials after P11 were identified for all patients with a noncephalic reference but not with an ear reference.
