| vaginal birth after cesarian section | It was once the rule that after a c-section, the next delivery also had to be by c-section. Now vaginal delivery after cesarian section (vbac) is frequently feasible. See: vbac. (12 Dec 1998) |

| parasagittal section | A cross section obtained by slicing, actually or through imaging techniques, the body or any part of the body, or any anatomic structure in the sagittal plane, i.e., in a vertical plane parallels to the median plane. Since actual sectioning in the sagittal plane results in a right and a left portion, an anatomical sagittal section may be a two-dimensional view of the cut surface on the medial aspect of either portion. Synonym: parasagittal section. (05 Mar 2000) |
| relative biological effectiveness | The ratio of radiation dosages required to produce identical change based on a formula comparing other types of radiation with that of gamma or roentgen rays. (12 Dec 1998) |
| median section | A cross section attained by slicing in the median plane, actually or through imaging techniques, the body or any part of the body which occupies or crosses the median plane or by slicing any generally symmetrical anatomic structure, such as a finger or a cell, in its midline. Since actual sectioning the median plane results in a right and a left half, an anatomical median section may be a two-dimensional view of the cut surface on the medial aspect of either half. Synonym: midsagittal section. (05 Mar 2000) |
| cesarean section | A surgical procedure that involves the delivery of the foetus through an abdominal incision. C-sections account for about 1/5 of all births in the us. Indications include: failure to progress, foetal distress, cephalopelvic disproportion (baby's too big for birth canal), placenta previa, placental abruption, placental insufficiency, breech baby, active genital herpes, multiple gestation, preeclampsia and excessive scarring from previous surgeries. The average hospital stay is about 4 days. The maternal death rate with C-section is three times higher than with natural delivery. (27 Sep 1997) |
| cesarean section, repeat | Extraction of the foetus by abdominal hysterotomy anytime following a previous cesarean. (12 Dec 1998) |
| cesarian section | The obstetrical procedure is often spelled this way in the U.S. With just an e although the Roman emperor remains Caesar in America with an ae. Procedure in which an infant, rather than being born vaginally, is surgically removed from the uterus. Also referred to as a C section. As the name Caesarian suggests, this is not exactly a new procedure. It was done in ancient civilizations upon the death of a near-full-term pregnant woman to salvage the baby. Julius Caesar (or one of his predecessors) was born by this procedure. Hence, the name Caesarian. The term section in surgery refers to the division of tissue. What is being divided here is the abdominal wall of the mother as well as the wall of the uterus in order to extract the baby. In Shakespeare's Macbeth the Witches' prophecy was that..none of woman born/ Shall harm Macbeth (IV.i). Unfortunately for Macbeth, the Scottish nobleman Macduff was from his mother's womb/ Untimely ripped. And thus not naturally born of woman (V.vii). Macduff was the only agent capable of destroying Macbeth. He killed Macbeth in battle. See: Caesarian section. (12 Dec 1998) |
| cesarian section, lower segment | A Cesarian section in which the surgical incision (cut) is made in the lower segment of the uterus. (12 Dec 1998) |
| cesarian section, vaginal birth after | It was once the rule that after a C-section, the next delivery also had to be by C-section. Now vaginal delivery after Cesarian section (VBAC) is frequently feasible. (12 Dec 1998) |
| perineal section | Any section through the perineum, either lateral or median lithotomy or external urethrotomy. (05 Mar 2000) |
| permanent section | A technique in which a thin slice of biopsy tissue is mounted on a slide to be examined under a microscope by a pathologist in order to establish a diagnosis. (09 Oct 1997) |
| pest control, biological | The use of biological mechanisms, usually involving living organisms such as bacteria, for the reduction or regulation of the population of noxious, destructive, or dangerous pests. Environmental concerns have focused attention on natural forms of disease control as potentially safe and effective alternatives to chemical pesticides. This has led to increased efforts to develop control strategies that rely on natural predators and parasites or that involve genetically engineered microbial pest control agents. (12 Dec 1998) |
| microscopic section | 1. The act of cutting, or separation by cutting; as, the section of bodies. 2. A part separated from something; a division; a portion; a slice. Specifically: A distinct part or portion of a book or writing; a subdivision of a chapter; the division of a law or other writing; a paragraph; an article; hence, the character, often used to denote such a division. "It is hardly possible to give a distinct view of his several arguments in distinct sections." (Locke) A distinct part of a country or people, community, class, or the like; a part of a territory separated by geographical lines, or of a people considered as distinct. "The extreme section of one class consists of bigoted dotards, the extreme section of the other consists of shallow and reckless empirics." (Macaulay) One of the portions, of one square mile each, into which the public lands of the United States are divided; one thirty-sixth part of a township. These sections are subdivided into quarter sections for sale under the homestead and preemption laws. 3. <geometry> The figure made up of all the points common to a superficies and a solid which meet, or to two superficies which meet, or to two lines which meet. In the first case the section is a superficies, in the second a line, and in the third a point. 4. A division of a genus; a group of species separated by some distinction from others of the same genus; often indicated by the sign . 5. A part of a musical period, composed of one or more phrases. See Phrase. 6. The description or representation of anything as it would appear if cut through by any intersecting plane; depiction of what is beyond a plane passing through, or supposed to pass through, an object, as a building, a machine, a succession of strata; profile. In mechanical drawing, as in these Illustrations of a cannon, a longitudinal section (a) usually represents the object as cut through its center lengthwise and vertically; a cross or transverse section (b), as cut crosswise and vertically; and a horizontal section (c), as cut through its center horizontally. Oblique sections are made at various angles. In architecture, a vertical section is a drawing showing the interior, the thickness of the walls, ets, as if made on a vertical plane passed through a building. <mathematics> Angular sections, an instrument to aid in drawing a series of equidistant parallel lines, used in representing sections. Thin sections, a section or slice, as of mineral, animal, or vegetable substance, thin enough to be transparent, and used for study under the microscope. Synonym: Part, portion, division. Section, Part. The English more commonly apply the word section to a part or portion of a body of men; as, a section of the clergy, a small section of the Whigs, etc. In the United States this use is less common, but another use, unknown or but little known in England, is very frequent, as in the phrases "the eastern section of our country," etc, the same sense being also given to the adjective sectional as, sectional feelings, interests, etc. Origin: L. Sectio, fr. Secare, sectum, to cut; akin to E. Saw a cutting instrument: cf. F. Section. See Saw, and cf. Scion, Dissect, Insect, Secant, Segment. Source: Websters Dictionary (01 Mar 1998) |
| midsagittal section | A cross section attained by slicing in the median plane, actually or through imaging techniques, the body or any part of the body which occupies or crosses the median plane or by slicing any generally symmetrical anatomic structure, such as a finger or a cell, in its midline. Since actual sectioning the median plane results in a right and a left half, an anatomical median section may be a two-dimensional view of the cut surface on the medial aspect of either half. Synonym: midsagittal section. (05 Mar 2000) |
| classical cesarean section | A cesarean section in which the uterus is entered through a vertical fundal incision. (05 Mar 2000) |
