Detection of the intranuclear microsporidian Enterospora nucleophila in gilthead sea bream by in situ hybridization.

Enterospora nucleophila is an intranuclear microsporidian responsible for emaciative microsporidiosis of gilthead sea bream (GSB). Its minute size and cryptic nature make it easily misdiagnosed. An in situ hybridization (ISH) technique based on antisense oligonucleotide probes specific for the parasite was developed and used in clinically infected GSB in combination with calcofluor white stain (CW) and other histopathological techniques.

Evaluating the Amount of Tooth Movement and Root Resorption during Canine Retraction with Friction versus Frictionless Mechanics Using Cone Beam Computed Tomography.

Background: The current study was carried out to compare the amount of tooth movement during canine retraction comparing two different retraction mechanics; friction mechanics represented by a NiTi closed coil spring versus frictionless mechanics represented by T - loop, and their effect on root resorption using Cone Beam Computed Tomography (CBCT).

Method: Ten patients were selected in a split-mouth study design that had a malocclusion that necessitates the extraction of maxillary first premolars and retraction of maxillary canines. The right maxillary canines were retracted using T - loops fabricated from 0.

Evaluation of risk factors for intrafamilial transmission of HCV infection in Egypt.

The objectives of this study were to define the prevalence of intrafamilial transmission of HCV and evaluate the risk factors in this setting. A cross-sectional, family-based seroepidemiological study was performed in Cairo Liver Center and Oncology Diagnostic Unit, Ain Shams University. A total of 102 index patients (72 males and 30 females) with type C chronic liver disease and their 305 family contacts were studied.

Position of cerebellar tonsils in the normal population and in patients with Chiari malformation: a quantitative approach with MR imaging.

Magnetic resonance imaging was used to define quantitatively the position of the cerebellar tonsils in the normal population and in patients with Chiari malformations. The average distance of the tonsillar tips from the foramen magnum was 2.9 +/- 3.
