Body Mass Index
|
D015992 |
[An indicator of body density as determined by the relationship of BODY WEIGHT to BODY HEIGHT. BMI=weight (kg)/height squared (m2). BMI correlates with body fat (ADIPOSE TISSUE). Their relationship varies with age and gender. For adults, BMI falls into these categories: below 18.5 (underweight); 18.5-24.9 (normal); 25.0-29.9 (overweight); 30.0 and above (obese).

Protein Conformation, alpha-Helical
|
D000072756 |
[A secondary structure of proteins that is a right-handed helix or coil, where each amino (N-H) group of the peptide backbone contributes a hydrogen bond to the carbonyl(C=O) group of the amino acid four residues N-terminal to it (n-4). It is the most common type of secondary structure.

Life Tables

D015993 |
[Summarizing techniques used to describe the pattern of mortality and survival in populations. These methods can be applied to the study not only of death, but also of any defined endpoint such as the onset of disease or the occurrence of disease complications.

Protein Conformation, beta-Strand
|
D000072757 |
[A secondary structure of proteins where the amino (N-H) groups of a polypeptide backbone, three to ten amino acids in length, establish hydrogen bonds with the carbonyl (C=O) groups in the backbone of adjacent strands. These may form a beta-sheet, where the side chains of the adjacent strands point in the same direction.
, A type of secondary structure that occurs between lateral beta strands connected by at least two or three backbone hydrogen bonds. Multiple beta-sheets may associate to form PROTEIN AGGREGATES.

Semaphorins
|
D039961 |
[Transmembrane proteins involved in axonal guidance of peripheral neurons in the developing CNS of invertebrates. Semaphorin-1 refers to the class of SEMAPHORINS with an extracellular sema domain and a short cytoplasmic domain. Sema-1 was first identified in grasshopper as fasciclin IV, and has since been described in Drosophila and C. elegans. Two distinct members of this class of semaphorins exist: SEMA-1a (the original sema-1) and SEMA-1b, a homologous protein isolated from Drosophila which may be more important for neuronal differentiation than migration.
, A family of proteins that mediate AXONAL GUIDANCE. Semaphorins act as repulsive cues for neuronal GROWTH CONES and bind to receptors on their filopodia. At least 20 different molecules have been described and divided into eight classes based on domain organization and species of origin. Classes 1 and 2 are invertebrate, classes 3-7 are vertebrate, and class V are viral. Semaphorins may be secreted (classes 2, 3, and V), transmembrane (classes 1, 4, 5, and 6), or membrane-anchored (class 7). All semaphorins possess a common 500-amino acid extracellular domain which is critical for receptor binding and specificity, and is also found in plexins and scatter factor receptors. Their C termini are class-specific and may contain additional sequence motifs.

Survival Rate
|
D015996 |
[The proportion of survivors in a group, e.g., of patients, studied and followed over a period, or the proportion of persons in a specified group alive at the beginning of a time interval who survive to the end of the interval. It is often studied using life table methods.

|
Neonatal Screening
|
D015997 |
[The identification of selected parameters in newborn infants by various tests, examinations, or other procedures. Screening may be performed by clinical or laboratory measures. A screening test is designed to sort out healthy neonates (INFANT, NEWBORN) from those not well, but the screening test is not intended as a diagnostic device, rather instead as epidemiologic.

Incidence
|
D015994 |
[The number of new cases of a given disease during a given period in a specified population. It also is used for the rate at which new events occur in a defined population. It is differentiated from PREVALENCE, which refers to all cases in the population at a given time.

Prevalence

D015995 |
[The total number of cases of a given disease in a specified population at a designated time. It is differentiated from INCIDENCE, which refers to the number of new cases in the population at a given time.
