In this study, we synthesis one-dimensional (1D) manganese(III) Schiff base coordination polymer [Mn(Brsalophen)(μ1,3-N3)]n by reaction of MnCl2·6H2O and tetradentate Schiff base ligand Brsalophen at the presence of NaN3 in methanol and characterized by elemental analyses (CHN) and FT-IR spectroscopy. It was used as a new precurs...

Simultaneous visualization of tissue and surgical instruments is necessary during ultrasound-guided medical procedures. Standard minimally invasive instruments are typically metallic and act as strong specular scatterers. As a result, such instruments saturate the image or disappear according to the angle of incidence, obscuring nearby tissue and making it difficult to determine the instrument'...

Electropolishing of metal surfaces is a benign alternative to mechanical treatment. Ionic liquids are considered as green electrolytes for the electropolishing metals. They demonstrate number advantages in comparison with acid aqueous solutions and other methods producing smooth or mirror-like that required by diverse applications (medical instruments, special equipment, implants prostheses, et...

INTRODUCTION Modern medicine employs a wide variety of instruments with different physiological effects and measurements. Periodic verifications are routinely used in legal metrology for industrial measuring instruments. The correct operation of electrosurgical generators is essential to ensure patient's safety and management of the risks associated with the use of high and low frequency electr...

Prions, transmissible agents that cause Creutzfeldt-Jakob disease (CJD) and other prion diseases, are known to resist conventional sterilization procedures. Iatrogenic transmission of classical CJD via neurosurgical instruments is well documented and the involvement of lymphoreticular tissues in variant CJD (vCJD), together with the unknown population prevalence of asymptomatic vCJD infection, ...

The growing use of NiTi rotary instruments in dental practice demands a good understanding of their concept of alloy and design in relation to improved properties and inherent limitations. Nickel titanium's super elasticity allows more centered canal preparations with less transportation and a decreased incidence of canal aberrations. Furthermore, the production of files with increased taper be...

The procedures for purchasing surgical instruments and consumables are similar to those for purchasing equipment, which were addressed in our “Equipment for eye care” issue (number 73, September 2010). The major difference with consumables is that the number of items in stock (the ‘stock level’) must be monitored constantly. Consumables are generally fast moving and require frequent replacement...
