Unilateral labyrinthectomy (UL) in rats is used as a human vertigo model. In this model, spontaneous nystagmus and dysequilibrium caused by UL are ameliorated within 48-72 hours. The amelioration, termed vestibular compensation (VC), is long lasting. Although cerebellar flocculi have been reported to be involved in VC, the molecular mechanisms behind VC are unknown. In this study, we used 2D-DI...

In the mammalian testis, the ubiquitin-proteasome system plays important roles in the process that promotes the formation of mature sperm. We recently identified zygote-specific proteasome assembly chaperone (ZPAC), which is specifically expressed in the mouse gonads and zygote. ZPAC mediates a unique proteasome assembly pathway in the zygote, but the expression profile and function of ZPAC in ...

A case report of primary twin ovarian pregnancy is presented. A 36 year old woman, gravida 4 para 3, was admitted to the hospital for suspected ectopic pregnancy, with vaginal bleeding at 11 weeks after her last menstrual period, associated with pelvic pain. An endovaginal ultrasonography led to the diagnosis of twin ovarian right ectopic pregnancy with two dead fetuses associated with a compar...

BACKGROUND The aim of this study was to define determinants of fertility in patients treated conservatively for mucinous borderline ovarian tumours (MBOTs), and to compare outcomes after salpingo-oophorectomy or cystectomy. METHODS This was a retrospective cohort study of fertility results in a series of patients treated conservatively for MBOTs and desiring pregnancy. Conservative surgery was ...

PURPOSE The goal of this study was to determine whether non immersive interactive virtual environments are an effective medium for training individuals who suffer from Unilateral Spatial Neglect (USN) as a result of a right hemisphere stroke, and to compare it to a standard computer visual scanning training. METHOD Participants included 19 patients with right hemisphere stroke in two groups, ...

Patients with unilateral spatial neglect (USN) often show impaired performance in spatial working memory tasks, apart from the difficulty retrieving "left-sided" spatial data from long-term memory, shown in the "piazza effect" by Bisiach and colleagues. This study's aim was to compare the effect of the spatial position of a visual object on immediate and delayed memory performance in USN patien...

Sweating is a physiological process, which is vital for maintaining a constant body temperature and good grip function. Excessive sweating (hyperhidrosis) can on the contrary lead to severe social problems for the affected individual with a decreased quality of life (1). Primary or essential hyperhidrosis is seen symmetrically located to palms, feet, axillae and groins/anogential or generalised...

Introduction Retinoblastoma is a primary malignant intraocular neoplasm that arise from immature retinoblasts with in developing retina. The commonest presenting sign in developing country is proptosis which is the late presenting sign. We report presenting signs of retinoblastoma in Ethiopian children seen at a tertiary level teaching hospitals in Ethiopia. Methods Prospective case series st...

− Malformations of the cerebral cortex (MCC) are often associated with severe epilepsy and developmental delay. About 40% of drug-resistant epilepsies are caused by MCC. Classification of MCC is based on embryological brain development, recognising forms that result from faulty neuronal proliferation, neuronal migration and cortical organisation. Hemimegalencephaly, an enlarged dysplastic hemis...

Neuronal heterotopia are seen in various pathologies and are associated with intractable epilepsy. We examined brain tissue from four children with subcortical or periventricular nodular heterotopia of different aetiologies: one with severe epilepsy following focal brain trauma at 17 weeks gestation, one with hemimegalencephaly and intractable epilepsy, one with focal cortical dysplasia and int...
