We derived recombinant vesicular stomatitis virus (VSV) expressing either influenza virus hemagglutinin (HA) or neuraminidase (NA) glycoproteins from extra genes inserted in the viral genome. The HA protein was expressed from a site downstream of the VSV glycoprotein (G) gene, while NA protein was expressed from a site upstream of the VSV G gene. The HA protein was expressed at lower levels tha...

Background: Currently, the detection of retained wood is a frequent but challenging task in emergency care. The purpose of this study is to demonstrate improved foreign-body detection with the novel approach of preclinical X-ray dark-field radiography. Methods: At a preclinical dark-field x-ray radiography, setup resolution and sensitivity for simultaneous detection of wooden and metallic parti...

Despite the relevance to most aspects of crystallization, a comprehensive understanding of the kinetics of heterogeneous nucleation has not been well established yet. In this paper, a new kinetic model based on the ‘‘steady-state’’ approach will be put forward to describe both heterogeneous and homogeneous nucleation. As a key point in this model, the effect of foreign particles on both the nuc...

Eight sarcomas induced in mouse strains CBA/H, CBA/HT6, and C57BL/10ScSn (or their hybrids) by s.c. implantation of smooth or roughened plastic films or glass pieces were examined electron microscopically. Type A virus particles were detected within dilated ergastoplasmic cisternae of the sarcoma cells from five mice. The doughnut-shaped particles measured 90 to 100 nm and were seen to bud from...

PURPOSE To determine the nature and the origin of metallic foreign particles appearing on the iris after phacoemulsification surgery. SETTING P.D. Hinduja Hospital and Medical Research Centre, Mumbai, Maharashtra, India. DESIGN Case series. METHODS Metallic foreign particles were observed on the iris surface and the pupillary border on the first postoperative visit after phacoemulsificati...

A model of diffusion accounting for a distribution of barriers heights is developed. It is demonstrated that activation energy of diffusion depends on the maximal height of barrier that is to be overcome, not on the average height of barriers. The temperature dependence of diffusivity (respectively of ion conductivity) declines from strict Arrhenius behavior, although the declination is not as ...

Trichophytobezoars are uncommon foreign bodies, formed by hairs and vegetable matter with impacted food particles. We report an unusual case of a 5-year-old girl with large terminal ileal trichophytobezoar causing perforation peritonitis.

Objective: To define the clinical spectrum of tracheobronchial foreign body aspiration in adults, evaluate the efficacy of bronchoscopy, and determine outcome and complications at King Hussein Medical Center. Methods: Retrospective analysis of 33 consecutive clinical series from a referral-based medical center (King Hussein Medical Center) was conducted. Case records of 33 adult patients (over ...
