The objective of this study was to test the hypothesis that ultrasound covers and sonographic gels, used during vaginal ultrasound, are toxic for mouse embryonic development in vitro. A prospective randomized design was used on pronucleate ova of F1 hybrid CBA x C57Bl female mice. The mice were superovulated with pregnant mare's serum gonadotrophin and human chorionic gonadotrophin and mated wi...

Forty disposable medical shoe covers were briefly exposed to the surgical floor and were found contaminated by a large number of bacteria. This study also demonstrated live bacteria, including pathogens attached to contaminated shoe covers, can be subsequently transferred to surgical bedsheets. We suggest an infection control policy should be considered to prevent patients returning to their be...

The analysis of changes in the linear characteristics ropes made polyamide, polypropylene and polyethylene, which were divided into three groups, was carried out. Each group included above ropes. With these storage technology simulated for two years under various conditions after exposure to a single load, approximately equal half breaking load each type rope.

Cross-linked polyethylene (XLPE) is primarily used as a coating and insulator for electrical wires cables. The cross-links render recycling through remelting unfeasible, XLPE waste usually incinerated or sent to landfills. Previous investigations showed that increased the impact strength of commodity thermoplastics. Hence, incorporating in polyamide 12, an engineering thermoplastic, was studied...
