| parainfluenza virus 1, human | The type species of paramyxovirus also called haemadsorption virus 2 (ha2), which causes laryngotracheitis in humans, especially children. (12 Dec 1998) |
|---|---|
| parainfluenza virus 2, human | A species of rubulavirus associated particularly with acute laryngotracheitis (croup) in children aged 6 months to 3 years. (12 Dec 1998) |
| parainfluenza virus 3, human | A species of paramyxovirus frequently isolated from small children with pharyngitis, bronchitis, and pneumonia. (12 Dec 1998) |
| genetic human male | An individual with a karyotype containing a Y chromosome, an individual whose cell nuclei do not contain Barr sex chromatin bodies, which are normally present in females. Patients with ambiguous sexual development and those with Turner's syndrome are classed as genetic male's or genetic females according to the absence or presence of Barr bodies even though their sex chromosome complement may suggest otherwise. (05 Mar 2000) |
| genome, human | All of the genetic information, the entire genetic complement, all of the DNA in a person. Humanity's DNA is the treasury of human inheritance. It is this extraordinary repository of genetic information which the Human Genome Project in the United States and comparable programs in other countries around the world that belong to HUGO (the HUman Genome Organisation) are designed to fully fathom. (12 Dec 1998) |
| parts of human body | The head, neck, trunk, and limbs. Synonym: partes corporis humani. (05 Mar 2000) |
| parvovirus b19, human | The sole species of erythrovirus and the aetiological agent of erythema infectiosum, a disease most commonly seen in school-age children. (12 Dec 1998) |
| virus, human papilloma | A family of over 60 viruses responsible for causing warts. The majority of the viruses produce warts on the hands, fingers, and even the face. most of these viruses are innocuous, causing nothing more than cosmetic concerns. Several types of HPV are confined primarily to the moist skin of the genitals, producing genital warts and elevating the risk for cancer of the cervix. These viruses that cause wartlike growths on the genitals and contribute to cancer of the cervix are sexually transmitted. (12 Dec 1998) |
| respiratory syncytial virus, human | The type species of pneumovirus and an important cause of lower respiratory disease in infants and young children. It frequently presents with bronchitis and bronchopneumonia and is further characterised by fever, cough, dyspnea, wheezing, and pallor. (12 Dec 1998) |
| gonadotropin, human chorionic | A human hormone made by chorionic cells (in the foetal part of the placenta), hCG is directed at the gonads and stimulates them. HCG becomes detectable (by immunologic means) within days of fertilization and forms the foundation of the common pregnancy tests. The level of hCG in maternal serum also enters as one component in the double and the triple screens used during pregnancy to assign risks of Down syndrome and other foetal disorders. (12 Dec 1998) |
| chorionic gonadotropin, beta subunit, human | The beta subunit of human chorionic gonadotropin. It is used as a clinical marker to facilitate early detection of normal pregnancy and significantly contributes to the diagnosis of various pregnancy-related disorders, such as ectopic pregnancy, spontaneous abortion, hydatidiform mole, choriocarcinoma, or trisomy 21. Further, determination of this marker is immensely helpful to guide curative intervention in testicular cancer. Other possible clinical uses includes as a marker of cancers of the bladder, pancreas, or biliary tract. (scan j clin lab invest suppl 1993;216:97-104) (12 Dec 1998) |

| chromosomes, human | The structures within the human cell nucleus that contain the hereditary material, DNA. There are 46 chromosomes normally present in the human, including two which determine the sex of individual, xx for the female and xy for the male. Human chromosomes are classified into groups sharing structural similarity in terms of length from the centromere. (12 Dec 1998) |
| chromosomes, human, 1-3 | One of the seven groups of chromosomes containing three pairs conventionally named pairs 1, 2, and 3. The chromosomes in this group, also called group a, are large chromosomes with centromeres approximately in the middle. (12 Dec 1998) |
| chromosomes, human, 13-15 | The fourth of the seven groups of chromosomes containing three pairs conventionally named pairs 13, 14, and 15. The chromosomes in this group, also called group d, are medium sized with centromeres in the acrocentric position. (12 Dec 1998) |
