All individuals in MeSH

Label Id Description
Postural Balance D004856 [A POSTURE in which an ideal body mass distribution is achieved. Postural balance provides the body carriage stability and conditions for normal functions in stationary position or in movement, such as sitting, standing, or walking. ]
Postural Orthostatic Tachycardia Syndrome D054972 [A syndrome of ORTHOSTATIC INTOLERANCE combined with excessive upright TACHYCARDIA, and usually without associated ORTHOSTATIC HYPOTENSION. All variants have in common an excessively reduced venous return to the heart (central HYPOVOLEMIA) while upright. ]
Posture D011187 [The position or physical attitude of the body. ]
Potamogetonaceae D031821 [A plant family of the order Najadales, subclass Alismatidae, class Liliopsida (monocotyledons). ]
Potassium D011188 [An element in the alkali group of metals with an atomic symbol K, atomic number 19, and atomic weight 39.10. It is the chief cation in the intracellular fluid of muscle and other cells. Potassium ion is a strong electrolyte that plays a significant role in the regulation of fluid volume and maintenance of the WATER-ELECTROLYTE BALANCE. ]
Potassium Acetate D019347 [A potassium salt used to replenish ELECTROLYTES, for restoration of WATER-ELECTROLYTE BALANCE, as well as a urinary and systemic alkalizer, which can be administered orally or by intravenous infusion. Formerly, it was used in DIURETICS and EXPECTORANTS. ]
Potassium Channel Blockers D026902 [A class of drugs that act by inhibition of potassium efflux through cell membranes. Blockade of potassium channels prolongs the duration of ACTION POTENTIALS. They are used as ANTI-ARRHYTHMIA AGENTS and VASODILATOR AGENTS. ]
Potassium Channels D015221 [Cell membrane glycoproteins that are selectively permeable to potassium ions. At least eight major groups of K channels exist and they are made up of dozens of different subunits. ]
Potassium Channels, Calcium-Activated D024681 [Potassium channels whose activation is dependent on intracellular calcium concentrations. ]
Potassium Channels, Inwardly Rectifying D024661 [Potassium channels where the flow of K+ ions into the cell is greater than the outward flow. ]
Potassium Channels, Sodium-Activated D000081033 [Potassium channels whose activation is dependent on intracellular sodium concentrations. ]
Potassium Channels, Tandem Pore Domain D024683 [Potassium channels that contain two pores in tandem. They are responsible for baseline or leak currents and may be the most numerous of all K channels. ]
Potassium Channels, Voltage-Gated D024642 [Potassium channel whose permeability to ions is extremely sensitive to the transmembrane potential difference. The opening of these channels is induced by the membrane depolarization of the ACTION POTENTIAL. ]
Potassium Chloride D011189 [A white crystal or crystalline powder used in BUFFERS; FERTILIZERS; and EXPLOSIVES. It can be used to replenish ELECTROLYTES and restore WATER-ELECTROLYTE BALANCE in treating HYPOKALEMIA. ]
Potassium Citrate D019357 [A powder that dissolves in water, which is administered orally, and is used as a diuretic, expectorant, systemic alkalizer, and electrolyte replenisher. ]
Potassium Compounds D017680 [Inorganic compounds that contain potassium as an integral part of the molecule. ]
Potassium Cyanide D011190 [A highly poisonous compound that is an inhibitor of many metabolic processes, but has been shown to be an especially potent inhibitor of heme enzymes and hemeproteins. It is used in many industrial processes. ]
Potassium Deficiency D011191 [A condition due to decreased dietary intake of potassium, as in starvation or failure to administer in intravenous solutions, or to gastrointestinal loss in diarrhea, chronic laxative abuse, vomiting, gastric suction, or bowel diversion. Severe potassium deficiency may produce muscular weakness and lead to paralysis and respiratory failure. Muscular malfunction may result in hypoventilation, paralytic ileus, hypotension, muscle twitches, tetany, and rhabomyolysis. Nephropathy from potassium deficit impairs the concentrating mechanism, producing POLYURIA and decreased maximal urinary concentrating ability with secondary POLYDIPSIA. (Merck Manual, 16th ed) ]
Potassium Dichromate D011192 [Chromic acid (H2Cr2O7), dipotassium salt. A compound having bright orange-red crystals and used in dyeing, staining, tanning leather, as bleach, oxidizer, depolarizer for dry cells, etc. Medically it has been used externally as an astringent, antiseptic, and caustic. When taken internally, it is a corrosive poison. ]
Potassium Iodide D011193 [An inorganic compound that is used as a source of iodine in thyrotoxic crisis and in the preparation of thyrotoxic patients for thyroidectomy. (From Dorland, 27th ed) ]
