The osmolar gap between true and the calculated osmolality, is made up of unmeasured substances like ketoacids. (bmj.com)
Osmolality and osmolar gap were not measured, nor was ketone body levels studied (Personal communication Glaser N ). Our studies demonstrates that the ketone level is probably a 'relevant variable ' that needs to be estimated before we can be certain that rapid decrease in extra-cellular osmolality did not occur. (bmj.com)
The concentration of combined solutes in water is osmolarity (amount of solute per L of solution), which, in body fluids, is similar to osmolality (amount of solute per kg of solution). (msdmanuals.com)
An osmolar gap is present when measured osmolality exceeds estimated osmolality by ≥ 10 mOsm/kg ( ≥ 10 mmol/kg). (msdmanuals.com)

Shift of sodium-free intracellular fluid into the extracellular compartment after mannitol infusion may lower serum sodium concentration and aggravate preexisting hyponatremia. (nih.gov)
Nine days following chemotherapy, her serum sodium concentration was found to be 104 mM, while her consciousness was drowsy with severe fatigue and vomiting. (elsevierpure.com)
Serum sodium concentration and urine output were considered as primary outcomes and body weight change and all-cause mortality as second outcomes. (bvsalud.org)
Intracellular sodium concentration is 12 mEq/L (12 mmol/L). (msdmanuals.com)
Extracellular sodium concentration averages 140 mEq/L (140 mmol/L). (msdmanuals.com)

The maximal plasma concentrations in humans occur within 1 hour after ingestion. (cdc.gov)

Body fluid volume and electrolyte concentration are normally maintained within very narrow limits despite wide variations in dietary intake, metabolic activity, and environmental stresses. (msdmanuals.com)

For example, if plasma osmolarity is 300 mOsm/L, urine osmolarity is 600 mOsm/L, and urine flow rate is 1 ml/min (0.001 L/ min), the rate of osmolar excretion is 0.6 mOsm/min (600 mOsm/L x 0.001 L/min) and osmolar clearance is 0.6 mOsm/min divided by 300 mOsm/L, or 0.002 L/min (2.0 ml/min). (brainkart.com)
At normally used concentrations, 25-76%, nonionic monomers have 290-860 mOsm/kg. (medscape.com)
Here's the deal: simple sugars (glucose, sucrose, fructose, dextrose, etc) need to be mixed in concentrations no higher than 6-8% in order to achieve an acceptable absortion osmolar value of body fluids (280-303 mOsm) and be digested with any efficiency. (hammernutrition.com)

Urinary elimination of electrolytes in response to treatments was evaluated, together with changes in concentrations of creatinine, urea, aldosterone, glucose and albumin in urine and plasma. (biomedcentral.com)

Even at this seemingly too-high concentration complex carbohydrates (such as maltodextrins/glucose polymers) will empty the stomach at the same efficient rate as normal body fluids and provide substantially more calories (up to three times more) than simple sugar mixtures will. (hammernutrition.com)

Low osmolar contrast medium with concentration of 300 mg/ml is used. (wikipedia.org)
Low osmolar contrast agent with concentration of 240 mg/ml is preferable in this study. (wikipedia.org)

Polyvalent cation-induced membrane aggregation was reversibly suppressed by high ionic strength as well as by metal ion chelators, irreversibly inhibited by the cross-linking agent glutaraldehyde, and enhanced by increasing concentrations of ethanol and increased temperature of the medium. (mcmaster.ca)

CONCLUSIONS: RS increased net water (and sodium) absorption from isosmolar and reduced osmolar ORS consistent with increased absorption by the colon. (uaeu.ac.ae)

Using the example discussed earlier, if urine flow rate is 1 ml/min and osmolar clearance is 2 ml/min, free-water clearance would be -1 ml/min. (brainkart.com)
The higher the water concentration, the higher the frequency, so the more water passes the membrane. (physicsforums.com)
Amount of water on the side doesn't matter, it is concentration that is important. (physicsforums.com)
Concentration of WATER. (physicsforums.com)
The higher the concentration of sucrose, the lower the concentration of water. (physicsforums.com)
Lactated Ringer's Injection 5% Dextrose, USP Rx is a sterile, nonpyrogenic solutions each containing isotonic concentrations of electrolytes (with or without dextrose) in water for injection. (dog.com)
The goals of her 11-month investigation are to determine (a) if urine color (U COL ), an inexpensive and practical tool, is a valid means of monitoring body water balance and (b) if U COL in 24 h and single samples accurately determines urine concentration. (karger.com)
Water crosses cell membranes freely from areas of low solute concentration to areas of high solute concentration. (msdmanuals.com)

High concentrations of oxalates may lead to formation of urinary calculi. (wordinfo.info)

The patterns of aggregation of microsomal membranes and further purified plasma membranes were almost identical whereas the aggregation of the heterogeneous mitochondrial membrane-enriched fraction was distinctly different in the initial rate of aggregation, its pH dependence, and metal ion concentration dependence. (mcmaster.ca)

If on one side of the membrane that ratio is higher, we say the osmolar concentration is higher. (physicsforums.com)

2. In biochemistry, an osmolar concentration of the body fluids that is abnormally increased. (wordinfo.info)
