Programmed Instructions as Topic
|
D011380 |
[Works about instruction in which learners progress at their own rate using workbooks, textbooks, or electromechanical devices that provide information in discrete steps, test learning at each step, and provide immediate feedback about achievement. (ERIC, Thesaurus of ERIC Descriptors, 1996).

Programming, Linear
|
D011382 |
[A technique of operations research for solving certain kinds of problems involving many variables where a best value or set of best values is to be found. It is most likely to be feasible when the quantity to be optimized, sometimes called the objective function, can be stated as a mathematical expression in terms of the various activities within the system, and when this expression is simply proportional to the measure of the activities, i.e., is linear, and when all the restrictions are also linear. It is different from computer programming, although problems using linear programming techniques may be programmed on a computer.

Progranulins
|
D000077153 |
[Cysteine-rich, precursor glycoproteins encoded by the granulin gene (GRN). They contain granulin-repeats separated by linker sequences that are cleaved by a variety of proteases to release the individual GRANULIN PEPTIDES. The mammalian progranulin is composed of a half-granulin repeat followed by 7 granulin repeats. The mammalian GRANULINS are named PARAGRANULIN and granulin 1-7 for their order in the progranulin propeptide. Progranulin has growth-factor like effects and is expressed over a broad range of tissues. Under-expression of progranulin is linked to neurodegenerative diseases including FRONTOTEMPORAL DEMENTIA and NEURONAL CEROID LIPOFUSCINOSIS, while over-expression is linked to metabolic diseases including OBESITY, and INSULIN RESISTANCE.

Progression-Free Survival
|
D000077982 |
[Length of time during and after the treatment of a disease, such as cancer, that a patient lives with the disease but the disease does not get worse.

|
Progressive Patient Care
|
D011383 |
[Organization of medical and nursing care according to the degree of illness and care requirements in the hospital. The elements are intensive care, intermediate care, self-care, long-term care, and organized home care.

Proguanil
|
D002727 |
[A biguanide compound which metabolizes in the body to form cycloguanil, an anti-malaria agent.

|
Proinsulin
|
D011384 |
[A pancreatic polypeptide of about 110 amino acids, depending on the species, that is the precursor of insulin. Proinsulin, produced by the PANCREATIC BETA CELLS, is comprised sequentially of the N-terminal B-chain, the proteolytically removable connecting C-peptide, and the C-terminal A-chain. It also contains three disulfide bonds, two between A-chain and B-chain. After cleavage at two locations, insulin and C-peptide are the secreted products. Intact proinsulin with low bioactivity also is secreted in small amounts.

Projection
|
D011385 |
[A defense mechanism, operating unconsciously, whereby that which is emotionally unacceptable in the self is rejected and attributed (projected) to others.

Projective Techniques

D011386 |
[Techniques to reveal personality attributes by responses to relatively unstructured or ambiguous stimuli.

Prokaryotic Cells
|
D011387 |
[Cells lacking a nuclear membrane so that the nuclear material is either scattered in the cytoplasm or collected in a nucleoid region.

Prokaryotic Initiation Factor-1
|
D039861 |
[The smallest of the three prokaryotic initiation factors with a molecular size of approximately 8 kD. It binds near the A-site of the 30S subunit of RIBOSOMES and may play a role in preventing premature addition of aminoacyl-tRNA-linked PEPTIDE ELONGATION FACTOR TU to the ribosome during the initiation of a peptide chain (PEPTIDE CHAIN INITIATION, TRANSLATIONAL).
] |
|
Prokaryotic Initiation Factor-2
|
D039881 |
[The largest of the three prokaryotic initiation factors with a molecular size of approximately 80 kD. It functions in the transcription initiation process by promoting the binding of formylmethionine-tRNA to the P-site of the 30S ribosome and by preventing the incorrect binding of elongator tRNA to the translation initiation site.
] |
|
Prokaryotic Initiation Factor-3
|
D039665 |
[A prokaryotic initiation factor that plays a role in recycling of ribosomal subunits for a new round of translational initiation. It binds to 16S RIBOSOMAL RNA and stimulates the dissociation of vacant 70S ribosomes. It may also be involved in the preferential binding of initiator tRNA to the 30S initiation complex.

|
Prokaryotic Initiation Factors
|
D039662 |
[Peptide initiation factors from prokaryotic organisms. Only three factors are needed for translation initiation in prokaryotic organisms, which occurs by a far simpler process than in PEPTIDE CHAIN INITIATION, TRANSLATIONAL of eukaryotic organisms.

|
Prolactin
|
D011388 |
[A lactogenic hormone secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). It is a polypeptide of approximately 23 kD. Besides its major action on lactation, in some species prolactin exerts effects on reproduction, maternal behavior, fat metabolism, immunomodulation and osmoregulation. Prolactin receptors are present in the mammary gland, hypothalamus, liver, ovary, testis, and prostate.

Prolactin Release-Inhibiting Factors
|
D011389 |
[A number of peptides with inhibitory activities on PROLACTIN release have been isolated from the HYPOTHALAMUS, the peripheral nervous system, and the gut. These include SOMATOSTATIN, and peptides derived from POMC and precursor for VASOPRESSIN-ASSOCIATED NEUROPHYSIN. Biogenic amine DOPAMINE is also a potent PIF.

|
Prolactin-Releasing Hormone
|
D056690 |
[A hypothalamic hormone that is synthesized as a precursor protein which is cleaved into two peptides. In addition to stimulating PROLACTIN release the peptides bind to specific G-PROTEIN-COUPLED RECEPTORS found at locations within the BRAIN.

Prolactinoma
|
D015175 |
[A pituitary adenoma which secretes PROLACTIN, leading to HYPERPROLACTINEMIA. Clinical manifestations include AMENORRHEA; GALACTORRHEA; IMPOTENCE; HEADACHE; visual disturbances; and CEREBROSPINAL FLUID RHINORRHEA.
