Background and Aims: Most children get a lot of anxiety while they visit a dentist. The most important factor in the child's fear at the beginning of treatment is the syringe and needle. Ways to cope with this anxiety include behavioural control techniques such as mental regeneration, distraction, and induction. The purpose of this study was to compare the pain and anxiety in children when usin...

To generate complete 3-D maps of extracellular ion current patterns around insect ovarioles without removing the sample and chamber from the recording equipment, it was necessary to design a chamber permitting complete rotation of the tissue. While suction pipets have been used in previous studies to orient the tissue (1), their use can significantly disturb extracellular ionic gradients if an ...

BACKGROUND Recently, equine multipotent mesenchymal stromal cells (MSC) have received significant attention as therapy for various conditions due to their proposed regenerative and immune-modulating capacity. MSC are commonly administered to the patient through a hypodermic needle. Currently, little information is available on the effect of such injection has on equine MSC immediate and delayed...

The method described by Rosenau 1 for injecting precise amounts of fluids into animals is excellent. In the practical application of this method certain difficulties have however been encountered, which, it is believed, can be overcome by improvements in the syringe herein described. The time reqtfired for removing the bulb of and measuring the salt solution into the syringe to wash i t out, af...

AIM To monitor ex vivo intra-canal irrigation with three endodontic needles (25, 27 and 30 gauge) and compare them in terms of irrigant flow rate, intra-barrel pressure, duration of irrigation and volume of irrigant delivered. METHODOLOGY A testing system was constructed to allow measurement of selected variables with pressure and displacement transducers during ex vivo intra-canal irrigation...

PURPOSE To describe an intravitreal injection technique using a commercially available 29-gauge insulin needle syringe (29GN syringe) and a 21-gauge (G) needle, comparing compound waste associated with this technique application and the one described in ranibizumab (Lucentis) kit instructions. METHODS Ten 0.3 ml doses of distilled water were aspirated using the 29GN syringe and 21G needle (PT...

The importance of post-mortem examination is generally accepted, not only for instruction and research, but also for raising the standard of medical practice. Unfortunately, there are many obstacles. In hospital, necropsies are limited by the natural reluctance of many relatives to give the necessary permission. In nursing homes and private houses, they are seldom performed because of the addit...

It has been the experience of this laboratory that the lead hydroxide stain of Watson (1) gives excellent results in increasing contrast in thin sections of tissue, but that the stain is inconvenient to use because on contact with air it forms an insoluble precipitate which contaminates both the stored solution and the sections. 1 Contamination introduced in transferring the solution from the s...
