In this study with randomized controls, we administered fludrocortisone acetate to 46 of 91 patients with subarachnoid hemorrhage in an attempt to prevent excessive natriuresis and plasma volume depletion. Fludrocortisone significantly reduced the frequency of a negative sodium balance during the first 6 days (from 63% to 38%, p = 0.041). A negative sodium balance was significantly correlated w...

Climate change, ozone depletion, water, air and soil pollution, deforestation, desertification, depletion of fisheries, waste accumulation loss biodiversity are becoming a growing barrier to economic development an increasingly important security threat, especially for developing countries. And in some cases even threat the existence all mankind. During coronavirus pandemic, anthropogenic press...

in order to study of effects of deficit irrigation on morphological traits and growth indices variation of corn forage (sc. 704) in rasht region, an experiment based on randomized complete design with four treatments and three replication was conducted in 2007 growing season, at research farm of faculty of agriculture, university of guilan. experimental treatments consisted of: no-irrigation, 1...

We have presented a case of rhabdomyolysis and myoglobinuria with resultant acute renal failure in association with varicella zoster infection, an association not previously described. A patient who has a severe varicella infection and volume depletion might be at risk for this life-threatening complication. Early recognition and prevention, together with appropriate support, might prevent this...

Renal dysfunction associated with bacterial endocarditis can occur via a number of different mechanisms: immune complex deposition with glomerulonephritis, antibiotic-induced acute interstitial nephritis, acute tubular necrosis secondary to toxin or volume depletion, emboli causing renal infarction, direct invasion of the parenchyma by the microorganism, and thrombotic microangiopathy with cort...

Multiarm star polymers were used as model grafted colloidal particles with long hairs, to study their size variation due to osmotic forces arising from added linear homopolymers of smaller size. This is the origin of the depletion phenomenon that has been exploited in the past as a means to melt soft colloidal glasses by adding linear chains and analyzed using dynamic light scattering experimen...

Caveolae have been implicated in sensing of cell volume perturbations, yet evidence is still limited and findings contradictory. Here, we investigated the possible role of caveolae in cell volume regulation and volume sensitive signaling in an adipocyte system with high (3T3-L1 adipocytes); intermediate (3T3-L1 pre-adipocytes); and low (cholesterol-depleted 3T3-L1 pre-adipocytes) caveolae level...

We present a new technique for the simultaneous measurement of cell volume changes and intracellular ionic activities in single cells. The technique uses measurement of changes in the concentration of intracellularly trapped fluorescent dyes to report relative cell volume. By using pH- or Ca(2+)-sensitive dyes and recording at the ion-sensitive and -insensitive (isosbestic) wavelengths, the met...

Atrial natriuretic peptide (ANP) provides a potent defense mechanism against volume overload in mammals. Its primary receptor, natriuretic peptide receptor-A (NPR-A), is localized mostly in the kidney, but also is found in hypothalamic areas involved in body fluid volume regulation. Acute glucocorticoid administration produces potent diuresis and natriuresis, possibly by acting in the renal nat...
