Water-Electrolyte Balance
Abstract
These results were further supported by polymerase chain reaction (PCR) analyses where there was no evidence for the existence of homologous genes to an ATP-driven, high-affinity potassium uptake system in Halococcus hamelinensis. To identify an alternative salt adaptation mechanism associated with...

Abstract
The results of treatment of 947 patients, suffering duodenal ulcer stenosis, to whom the enteral nutrition (EN) probe was introduced before and after operation, were analyzed. There was noted a positive impact of EN on metabolic processes, water-electrolyte balance, lowering of operative-anesthesiolo...

Abstract
The acute acclimatization to high altitude is underpinned by a diuresis (and to a lesser extent a natriuresis) that facilitates a reduction in plasma volume. This allows a haemoconcentration to occur that increases the oxygen carrying capacity of a given volume of blood, a vital effect in the presenc...

Abstract
Arginine vasopressin (AVP), also known as vasopressin or anti-diuretic hormone, is a neuropeptide produced in the hypothalamus. It is primarily responsible for osmoregulation and thus maintains body fluid homeostasis. It is also a potent vasoconstrictor, may have a role in higher cognitive functions...

Abstract
Acidocalcisomes of Trypanosoma cruzi are acidic calcium-containing organelles rich in phosphorus in the form of pyrophosphate (PP(i)) and polyphosphate (poly P). Acidification of the organelles is driven by vacuolar proton pumps, one of which, the vacuolar-type proton pyrophosphatase, is absent in ma...

Abstract
New analogs of some neurohypophyseal hormones (oxypressin, hydrin, glumitocin, vasotocin) have been synthesized. Experiments with injection of these peptides to rats showed that substitution of C-terminal glycinamide on beta-ethanolamine (glycinol) or ethylamine in 1-deamino-arginine vasotocin resul...

We measured copeptin in serum by a sandwich immunoassay. Injury severity was assessed by Glasgow Coma Score (GCS) and computed tomography, and recovery by Glasgow Outcome Score (GOS). Neuroendocrine and osmoregulation regulation were examined on day 0, 3 and 7, and 24 months post-injury. Copeptin wa...

There is growing evidence that early water and electrolyte homeostasis may be influenced by energy balance in preterm infants. Some fluid and electrolyte disturbances of postnatal life could be in part promoted by the catabolism due to withheld amino acid and energy supply after birth. According to...

Increased water intake of 3 L per day decreased Uosm in most ADPKD subjects. While urine [cAMP] accurately reflects changes in Uosm during acute water loading in ADPKD subjects, chronic water loading did not lower 24-hour urine cAMP excretion, although subjects with higher baseline [cAMP] (>2 nmol/m...

Renal failure affects the body's water-electrolyte balance. It is considered to be acute when it occurs abruptly, in a matter of hours or days. It is considered to be chronic when it lasts more than three months. Drugs are among the many causes of both acute and chronic renal failure. Their detrimen...
