Retrospective Studies
|
D012189 |
[Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.

Retroviridae
|
D012190 |
[Family of RNA viruses that infects birds and mammals and encodes the enzyme reverse transcriptase. The family contains seven genera: DELTARETROVIRUS; LENTIVIRUS; RETROVIRUSES TYPE B, MAMMALIAN; ALPHARETROVIRUS; GAMMARETROVIRUS; RETROVIRUSES TYPE D; and SPUMAVIRUS. A key feature of retrovirus biology is the synthesis of a DNA copy of the genome which is integrated into cellular DNA. After integration it is sometimes not expressed but maintained in a latent state (PROVIRUSES).

Retroviruses, Simian
|
D015301 |
[Classes of retroviruses for which monkeys or apes are hosts. Those isolated from the West African green monkey and the Asian rhesus macaque monkey are of particular interest because of their similarities to viruses causing cancer and acquired immunodeficiency syndrome (AIDS) in humans.

Rett Syndrome
|
D015518 |
[An inherited neurological developmental disorder that is associated with X-LINKED INHERITANCE and may be lethal in utero to hemizygous males. The affected female is normal until the age of 6-25 months when progressive loss of voluntary control of hand movements and communication skills; ATAXIA; SEIZURES; autistic behavior; intermittent HYPERVENTILATION; and HYPERAMMONEMIA appear. (From Menkes, Textbook of Child Neurology, 5th ed, p199)

Reunion
|
D017508 |
[One of the Indian Ocean Islands, east of Madagascar. Its capital is Saint-Denis. It was discovered in 1507 by the Portuguese and claimed by France in 1638. It was first colonized in 1662 as Isle de Bourbon but renamed Reunion in 1793. In 1946 it was made an overseas department of France. The name commemorates the reunion of the revolutionaries from Marseilles with the National Guard in Paris in 1792. (From Webster's New Geographical Dictionary, 1988, p1011; Room, Brewer's Dictionary of Names, 1992, p454; French Embassy)

D012193 |
[Any situation where an animal or human is trained to respond differentially to two stimuli (e.g., approach and avoidance) under reward and punishment conditions and subsequently trained under reversed reward values (i.e., the approach which was previously rewarded is punished and vice versa).

Review
|
D016454 |
[Work consisting of a more or less comprehensive review of the literature on a specific subject, with usually an extensive critical analysis and synthesis of the literature.
, Work consisting of a review of literature giving demographic, laboratory, and clinical data on a group of persons or animals ranging from most of the known cases of a rare condition in large populations on whom the results of research will lead to the establishing of epidemiological analyses or predictions of the occurrence and natural history of diseases.
, An article or book published after examination of published material on a subject. It may be comprehensive to various degrees and the time range of material scrutinized may be broad or narrow, but the reviews most often desired are reviews of the current literature. The textual material examined may be equally broad and can encompass, in medicine specifically, clinical material as well as experimental research or case reports. State-of-the-art reviews tend to address more current matters. A review of the literature must be differentiated from HISTORICAL ARTICLE on the same subject, but a review of historical literature is also within the scope of this publication type.
, Work consisting of complete literature reporting, to the best of the author's ability, of all known cases of a disease. The study is usually generated by the investigator's encounter with patients with a given disease and includes the investigator's own cases. The range of time will encompass historical cases and recent cases. The review usually cites the literature in which the known cases were published and may or may not include clinical and laboratory data.
, Work consisting of published material which provides an examination of recent or current literature. Reviews can cover a wide range of subject matter of various levels of completeness or comprehensiveness based on analyses of publications on the subject. The presence of research findings or case reports does not preclude designation as a review.

Review Literature as Topic
|
D012196 |
[Works about published materials which provide an examination of recent or current literature. These articles can cover a wide range of subject matter at various levels of completeness and comprehensiveness based on analyses of literature that may include research findings. The review may reflect the state of the art and may also include reviews as a literary form.
