Like other fluids of the human body, a gingival crevicular fluid (GCF) contains proteins, a diverse population of cells, desquamated epithelial cells, and bacteria from adjacent plaque. Proteomic tools have revolutionized the characterization of proteins and peptides and the detection of early disease changes in the human body. Gingival crevicular fluids (GCFs) are a very specific oral cavity f...

The presence of human herpesvirus 8 (HHV-8) was determined by polymerase chain reaction (PCR) in nasal secretions and saliva from 14 HHV-8-seropositive persons, including 8 Kaposi's sarcoma patients: 7 were human immunodeficiency virus type 1-infected, 6 of whom were asymptomatic. HHV-8 was detected in one or both body fluids in 8 (57%) of 14 subjects. Parallel PCR testing revealed the concomit...

When standard leads or ordinary prncordial leads are taken with a string galvanometer electro-cardiograph, the resistance of the patient can be measured for each lead. However, no method has been described previously by which the resistance at any of the extremities or at any point on the body can be measured. A method for doing this is described below. Principle. When the standard leads are ta...

miRNAs are small 22-nucleotide RNAs that can post-transcriptionally regulate gene expression. It has been proposed that dietary plant miRNAs can enter the human bloodstream and regulate host transcripts; however, these findings have been widely disputed. We here conduct the first comprehensive meta-study in the field, surveying the presence and abundances of cross-species miRNAs (xenomiRs) in 8...

We describe the rationale for an application ontology covering the domain of human body fluids that is designed to facilitate representation, reuse, sharing and integration of diagnostic, physiological, and biochemical data. We briefly review the Blood Ontology (BLO), Saliva Ontology (SALO) and Kidney and Urinary Pathway Ontology (KUPO) initiatives. We discuss the methods employed in each, and ...

Biomarkers are present in all parts of the body including body fluids and tissues. Most of the clinical laboratory examinations are done on body fluids such as blood and urine. Biomarkers can be detected on imaging studies or examination of body tissues. Even exhaled breath contains biomarkers. A wide range of technologies is utilized for detection of biomarkers and a number of assays are alrea...
