We describe a new technique of collecting sweat for measurement of osmolality and sodium concentrations. Eighty two subjects were studied--39 controls and 43 patients with cystic fibrosis. Adequate amounts of sweat were obtained in 81 subjects and sweat was analysed for both osmolality and sodium concentrations in 73 subjects. The 34 controls gave sweat osmolality and sodium values ranging from...

Background: We examined the usefulness of urine osmolality, as a predictive factor in the treatment of monosymptomatic nocturnal enuresis (NE) with combination therapy of imipramine and desmopressin. Methods: From May 2014 to April 2015, 59 monosymptomatic NE patients participated in this study. Early morning urine osmolality was measured at 1 week and 1 day before combination therapy of imipra...

BACKGROUND Serum osmolality is an accurate indicator of hydration status in older adults. Glucose, urea, and electrolyte concentrations are used to calculate serum osmolarity, which is an indirect estimate of serum osmolality, but which serum osmolarity equations best predict serum osmolality in the elderly is unclear. OBJECTIVE We assessed the agreement of measured serum osmolality with calc...

This study aimed to investigated the effect of cress seeds phenolic extract as an antioxidant on cations and osmolality rabbit seminal plasma. Four groups (24 male 10 female) rabbits were taken (N=6). First group was control (Distilled water) other received orally phenol (30, 60 90 mg/kg), once daily for days. The information concentrations plasma collected evaluated. copper, cadmium, lead pota...

Specific peripheral sensory neurons respond to increases in extracellular osmolality but the mechanism responsible for excitation is unknown. Here we show that small increases in osmolality excite isolated mouse dorsal root ganglion (DRG) and trigeminal ganglion (TG) neurons expressing the cold-sensitive TRPM8 channel (transient receptor potential channel, subfamily M, member 8). Hyperosmotic r...

Common sea stars (Asterias rubens) are at risk of physiological stress and decline with projected shifts in oceanic conditions. This study assessed changes coelomic fluid (CF) blood gases, electrolytes, osmolality, coelomocyte counts adult common after exposure to stressors mimicking effects from climate change for 14 days, including decreased pH (−0.4 units, mean: 7.37), hypoxia (target dissol...

BACKGROUND The filamentous fungus Aspergillus niger is a widely used strain in a broad range of industrial processes from food to pharmaceutical industry. One of the most intriguing and often uncontrollable characteristics of this filamentous organism is its complex morphology, ranging from dense spherical pellets to viscous mycelia depending on culture conditions. Optimal productivity correlat...

The unfertilized ova of Persian sturgeon, Acipencer persicus, were stored in the ovarian fluid at 18 C and fertilized after 0 (control), 3, 6, 9 and 12 hours post stripping using fresh and N pooled sperm obtained from three males. In addition, changes in the osmolality and pH of ovarian fluid during storage were recorded. After 3 h of storage, no significant differences were found between ferti...

BACKGROUND Mannitol and hypertonic saline are used to ameliorate brain edema and intracranial hypertension during and after craniotomy. We hypothesized that the agreement of measured and calculated serum osmolality during the infusion of hypertonic saline would be better than mannitol. The objective was to determine the accuracy of serum osmolality estimation by different formulas during the ad...

1 Purpose. To investigate pH and osmolality changes in the solutions stored in 2 contact lens cases, when different case rinsing and drying methods are used on 3 a daily basis. 4 Methods. Four multipurpose solutions (Opti-Free Express, Solo-Care Aqua, 5 Re-Nu Multiplus and Complete) and two hydrogen peroxide systems 6 (AOsept and Oxysept) were studied. Cases were filled with the solutions and 7...
