All individuals in MeSH

Label Id Description
Portulacaceae D029622 [A plant family of the order Caryophyllales, subclass Caryophyllidae, class Magnoliopsida. There are no true petals; each flower has two to six sepals. They produce betacyanin and betaxanthin pigments and lack anthocyanins. ]
Position-Specific Scoring Matrices D056510 [Tabular numerical representations of sequence motifs displaying their variability as likelihood values for each possible residue at each position in a sequence. Position-specific scoring matrices (PSSMs) are calculated from position frequency matrices. , The tabular notation of the count per position of each potential residue as observed from an aligned set of sequences. , A graph of the data from a position weight matrix using the letters of the residues drawn in a size that corresponds to their likelihood in the sequence. It is an alternative representation of the CONSENSUS SEQUENCE, including more information, specifically, the information about the less frequently occurring residues as well as the most frequently occurring residues. ]
Positive Regulatory Domain I-Binding Factor 1 D000074462 [A transcriptional repressor protein that contains an N-terminal PR-SET domain, four C-terminal CYS2-HIS2 ZINC FINGERS, and binds the PRDI element in the INTERFERON-BETA gene. It has methyltransferase activity and mediates gene transcription in tissue-specific innate and adaptive immune lymphocyte T-CELLS, repressing expression of proteins that promote exit of these tissue-specific T-cell populations from non-lymphoid organs. ]
Positive Transcriptional Elongation Factor B D042925 [A transcriptional elongation factor complex that is comprised of a heterodimer of CYCLIN-DEPENDENT KINASE 9 and one of several CYCLINS including TYPE T CYCLINS and cyclin K. It functions by phosphorylating the carboxy-terminal domain of RNA POLYMERASE II. ]
Positive-Pressure Respiration D011175 [A method of mechanical ventilation in which pressure is maintained to increase the volume of gas remaining in the lungs at the end of expiration, thus reducing the shunting of blood through the lungs and improving gas exchange. ]
Positive-Pressure Respiration, Intrinsic D018467 [Non-therapeutic positive end-expiratory pressure occurring frequently in patients with severe airway obstruction. It can appear with or without the administration of external positive end-expiratory pressure (POSITIVE-PRESSURE RESPIRATION). It presents an important load on the inspiratory muscles which are operating at a mechanical disadvantage due to hyperinflation. Auto-PEEP may cause profound hypotension that should be treated by intravascular volume expansion, increasing the time for expiration, and/or changing from assist mode to intermittent mandatory ventilation mode. (From Harrison's Principles of Internal Medicine, 12th ed, p1127) ]
Positive-Strand RNA Viruses D000085102 [RNA viruses that have their genetic material encoded in the form of single-stranded, positive-sense RNA. Unlike RETROVIRUSES they do not employ DNA intermediates in their life-cycle. ]
Positron Emission Tomography Computed Tomography D000072078 [An imaging technique that combines a POSITRON-EMISSION TOMOGRAPHY (PET) scanner and a CT X RAY scanner. This establishes a precise anatomic localization in the same session. ]
Positron-Emission Tomography D049268 [An imaging technique using compounds labelled with short-lived positron-emitting radionuclides (such as carbon-11, nitrogen-13, oxygen-15 and fluorine-18) to measure cell metabolism. It has been useful in study of soft tissues such as CANCER; CARDIOVASCULAR SYSTEM; and brain. SINGLE-PHOTON EMISSION-COMPUTED TOMOGRAPHY is closely related to positron emission tomography, but uses isotopes with longer half-lives and resolution is lower. ]
Post and Core Technique D011176 [Use of a metal casting, usually with a post in the pulp or root canal, designed to support and retain an artificial crown. ]
Post-Cardiac Arrest Syndrome D000080942 [A reperfusion syndrome characterized by various pathophysiological processes after CARDIAC ARREST. It may include post-cardiac arrest brain injury (HYPOXIA-ISCHEMIA, BRAIN), cardiocirculatory dysfunction, (e.g., systemic ISCHEMIA), HYPERGLYCEMIA; MULTIPLE ORGAN FAILURE and delayed death. ]
Post-Concussion Syndrome D038223 [The organic and psychogenic disturbances observed after closed head injuries (HEAD INJURIES, CLOSED). Post-concussion syndrome includes subjective physical complaints (i.e. headache, dizziness), cognitive, emotional, and behavioral changes. These disturbances can be chronic, permanent, or late emerging. ]
Post-Dural Puncture Headache D051299 [A secondary headache disorder attributed to low CEREBROSPINAL FLUID pressure caused by SPINAL PUNCTURE, usually after dural or lumbar puncture. ]
Post-Exercise Hypotension D057774 [Transient reduction in blood pressure levels immediately after exercises that lasts 2-12 hours. The reduction varies but is typically 5-20 mm Hg when compared to pre-exercise levels. It exists both in normotensive and hypertensive individuals and may play a role in excercise related PHYSIOLOGIC ADAPTATION. ]
Post-Exposure Prophylaxis D056990 [The prevention of infection or disease following exposure to a pathogen. ]
Post-Lyme Disease Syndrome D000077342 [A subjective syndrome that occurs following standard antibiotic treatment of Lyme disease. It includes FATIGUE; MUSCULOSKELETAL PAIN; and neurocognitive dysfunction. , A condition caused by long-lasting and ongoing infection with the spirochete Borrelia burgdorferi resulting in progressive inflammatory neurologic, neuromuscular, and dermatologic manifestations including ENCEPHALITIS; MYELITIS; acrodermatitis chronica atrophicans; and ARTHRITIS. ]
Post-Synaptic Density D057907 [Cytoskeleton specialization at the cytoplasmic side of postsynaptic membrane in SYNAPSES. It is involved in neuronal signaling and NEURONAL PLASTICITY and comprised of GLUTAMATE RECEPTORS; scaffolding molecules (e.g., PSD95, PSD93), and other proteins (e.g., CaCMKII). ]
Post-Traumatic Headache D051298 [Secondary headache attributed to TRAUMA of the HEAD and/or the NECK. ]
Postal Service D011177 [The functions and activities carried out by the U.S. Postal Service, foreign postal services, and private postal services such as Federal Express. ]
Postanesthesia Nursing D016528 [The specialty or practice of nursing in the care of patients in the recovery room following surgery and/or anesthesia. ]
