The objective was to investigate the anatomical substrate of ataxia seen after severe head injury. Five patients were recruited from present and former inpatients at Rivermead Rehabilitation Centre. All patients had had a closed head injury and all had cerebellar type ataxia. Four normal controls were also studied. Brain MRI, clinical examination, computer based recording, and analysis of visuo...

Two species referred to the callianassid ghost shrimp genus Rayllianassa Komai & Tachikawa, 2008 are reported herewith. Additional locality records from Japan are provided for R. amboinensis (de Man, 1888), and the synonymy of Callianassa ngochoae Sakai, 1999 with R. amboinensis is discussed. It is shown that R. amboinensis is associated with sponges or alcyonacean soft corals, representing unu...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2015210334 DESCRIPTION A 33-year-old man with a history of traumatic brain injury (TBI) from a few years prior, secondary to a high-speed motor vehicle accident, presented with worsening right-sided motor function. Brain MRI showed diffuse axonal injury, punctuate microbleedings, asymmetric...

The genus Odysseylana Malyutina, 1995 is revised and a new diagnosis presented; two new species from Singapore are described: Odysseylana sakijang sp. nov. and Odysseylana temasek sp. nov. The monotypic genus Parilcirolana Yu & Li, 2001, is placed in synonymy, bringing total number of species in Odysseylana to four including the type species Odysseylana sirenkoi Malyutina, 1995 and Odysseylana ...

BACKGROUND Approximately 10% of cases of hypertensive intracerebral hemorrhage are cerebellar hemorrhage. We report a case of intracerebellar hemorrhage in which the initial symptoms were hearing loss and tinnitus. SUMMARY OF REPORT A 45-year-old man suddenly complained of hearing loss and tinnitus on the right side. Computed tomography demonstrated a high-density area 1.2 cm in diameter in t...

Pethia longicauda, a new cyprinid fish, is described from Hiranyakeshi River, Krishna drainage, Maharashtra, India. It can be distinguished from congeners based on a combination of characters including: a long caudal peduncle, incomplete lateral line, absence of barbels, upper lip thick and fleshy, distinct lateral fold on snout, 22-24 scales in lateral series, 5-6 lateral-line pored scales, ni...

An ichthyofaunistic survey of Mekong tributaries in Lincang Prefecture, Yunnan Province, China yielded a new species of nemacheilid loach, herein described as Schistura sexnubes species nova. The new species is readily distinguishable from its congeners by the following combination of characters: 8+8 branched caudal fin rays, an incomplete lateral line, a dissociated caudal bar, a shallow cauda...

Circumnutation, the helical movement of growing organ tips, is ubiquitous in land plants. The mechanisms underlying circumnutation have been debated since Darwin's time. Experiments in space and mutant analyses have revealed that internal oscillatory (tropism-independent) movement and gravitropic response are involved in circumnutation. Female flower buds of tape grass (Vallisneria asiatica var...

Magnetic resonance imaging (MRI) brain scans were obtained from 19 infants at 7 months. Expressive and receptive language performance was assessed at 12 months. Voxel-based morphometry (VBM) identified brain regions where gray-matter and white-matter concentrations at 7 months correlated significantly with children's language scores at 12 months. Early gray-matter concentration in the right cer...

A 63-year-old woman presented with right hearing disturbance and vertigo. Magnetic resonance (MR) imaging revealed the presence of right vestibular schwannoma (VS). Stereotactic radiosurgery (SRS) was performed with a tumor marginal dose of 14 Gy using two isocenters. She was followed up clinically and neuroradiologically using three-dimensional spoiled gradient-echo MR imaging. She experienced...
