A survey of mysid crustaceans in near-shore habitats of the Cayman Islands and the Turks and Caicos Islands, BWI yielded two new species of mysids belonging to the genus Heteromysis S. I. Smith, 1873. H. (Olivemysis) modlini n. sp. occurred on live bottom habitats in shallow waters of Grand Cayman Island, and H. (Olivemysis) mclellandi n. sp. from sponges in depths of 21–27 m on deep fringing r...

Older male premutation carriers of the FMR1 gene are associated with the risk of developing a late-onset neurodegenerative disorder, fragile X-associated tremor/ataxia syndrome. Although previous postmortem and in vivo magnetic resonance imaging studies have indicated white matter pathology, the regional selectivity of abnormalities, as well as their relationship with molecular variables of the...

Fish propelled by body and/or caudal fin (BCF) locomotion can achieve high-efficiency and high-speed swimming performance, changing their motion to interact with external fluids. This flexural be prescribed through its curvature profile. work indicates that when the fish swims high efficiency, amplitude reaches a maximum at peduncle. In case of swimming, shows three maxima on entire length. It ...

We have investigated the properties of nerve cell precursors in hydra by analyzing the differentiation and proliferation capacity of interstitial cells in the peduncle of Hydra oligactis, which is a region of active nerve cell differentiation. Our results indicate that about 50% of the interstitial cells in the peduncle can grow rapidly and also give rise to nematocyte precursors when transplan...

Ischemically damaged brain can be accompanied by secondary degeneration of associated axonal connections e.g. Wallerian degeneration. Diffusion tensor imaging (DTI) is widely used to investigate axonal injury but the cellular correlates of many of the degenerative changes remain speculative. We investigated the relationship of DTI of directly damaged cerebral cortex and secondary axonal degener...

Normal human subjects and patients with lesions of the olivocerebellar system threw balls of clay at a visual target while wearing wedge prism spectacles. Normal subjects initially threw in the direction of prism-bent gaze, but with repeated throws adapted to hit the target. Patients with generalized cerebellar atrophy, inferior olive hypertrophy, or focal infarcts in the distribution of the po...
