Transnasal endoscopic orbital decompression is a viable alternative for external orbital decompression. Today, it can be performed due to the great development of endoscopic technology and specific endoscopic surgical instruments. It requires strong anatomic knowledge and skilled hands. We present our experience with endoscopic orbital decompression focusing on the surgical technique used in ou...

sold by surgical instrument makers, which have constantly come prominently to my notice daring the performnace of operations on the eye, and which, after considerable experience of the same, have forced me to try and effect a remedy for them. It is with that object in view, that I have devised an instrument, which I venture to bring before the notice of the profession, as having, in my humble o...

MAY 2005 C hromatography is the most powerful separation tool available to protein scientists and plays a central role in proteomics and functional biology. Problem solving in both areas requires purified proteins, but the purification requirements are different. In both types of research the samples are often complex mixtures derived from tissue homogenates, body fluids, or cell cultures. In p...

conclusions the use of absorbable tacks during tapp confers significant benefit regarding the operating time, however it is a disadvantage due to the cost when compared with fibrin glue. results the group of tacks ‘tapp’ showed good results concerning the level of pain, fatigue and foreign body sensation comparable with those of the historical group. there were significant differences concernin...

This paper reviews the current research on the speciation and determination of mercury by various analytical instruments such as, atomic absorption spectrometer (AAS), voltammeter, inductively coupled plasma optical emission spectrometer (ICP-OES), ICP-atomic emission spectrometer (AES), ICP-mass spectrometer (MS), atomic fluorescence spectrometer (AFS), spectrophotometer, spectrofluorometer, a...

Background: Broad spectrum drug screening, also known as systematic toxicological analysis or general unknown screening (GUS), is a method commonly used by clinical and forensic toxicology laboratories to detect a variety of drugs and metabolites in biological fluids. Recently, there has been much interest in liquid chromatography-high resolution mass spectrometry (LCHRMS) techniques for GUS as...

The aim of this paper is to know the compositions in unknown medicinal-lotion and to evolution its applications. Through a variety of studies, an analysis method was established. This method mainly is that samples were first extracted and pre-treated by concentration of compositions, and then they were separated and qualitatively analyzed by multiple-instruments. These instruments involve Mass ...

Chromatography is a high-technology instrument that widely used in the various industry for decades. Hence, Science Bachelor Graduates’ possesses ability to handle instrumentation are useful their job nature. Learning approach depends highly on lecture mode only enhance students’ knowledge chromatographic techniques, but they might not possess skills instruments handling. Therefore, learning of...
