Introduction Feed dilution or solids-liquid weight The English word "sedimentation" ratio is derived from the Latin verb "sedere" Size and shape of the particulate meaning to sink down. As a mineral solids processing unit operation, sedimentaSpecific gravity differential between tion has been defined as the separation the solids and liquid phases of a suspension into a supernatant presence of e...

This is a clinical update discussing the use of periendoscopic laboratory testing in common clinical situations. The Standards of Practice Committee of the American Society for Gastrointestinal Endoscopy (ASGE) prepared this document by using MEDLINE and PubMed databases to search for publications between January 1990 and December 2013 pertaining to this topic. The keywords “endoscopy” and “lab...

This review focuses on the laboratory diagnosis of Chlamydia trachomatis urogenital infections in adult patients. Laboratory diagnoses of C. trachomatis have rapidly evolved over the last two decades. The evolution from culture to enzyme immunoassay to nucleic acid amplification assay was a big step in the advance in technology. This advance has helped to improve the diagnosis and prevention of...

The lung is the primary organ likely to be exposed by inhalation studies and, therefore, measurement of changes in lung function are of particular interest to the pulmonary physiologist and toxicologist. Tests of pulmonary function have been developed which can be used with small animals to measure spirometry (lung volumes), mechanics, distribution of ventilation, gas exchange or control of ven...

The genetic testing in various clinical conditions emerges to have an important role in both diagnosis and treatment. Recently, a revolution in genomic technologies from the first-generation Sanger method to next-generation high through-put sequencing and microarrays has occurred. All of these technologies have been widely applied for genome, exome, transcriptome sequencing, and epigenomics. Th...
