The neurotoxic effects of therapy for childhood acute lymphoblastic leukemia can result in leukoencephalopathy or measurable deficits in cognitive function. However, there are no validated biomarkers that allow the identification of those patients at greatest risk. With the objective of identifying such predictors, cerebrospinal fluid collected from 53 patients over 2.5 years ...

Electrolyte abnormalities are common medical complications of traumatic brain injury (TBI). Hyponatremia is the most common of these disorders. The syndrome of inappropriate antidiuretic hormone and cerebral salt-wasting are the most well known causes of hyponatremia following TBI. In the presence of polydipsia and polyuria, psychogenic polydipsia should be included in the ...
Autosomal dominant polycystic kidney disease (ADPKD) is the most frequent inherited nephropathy. The development and enlargement of cysts in ADPKD requires tubular cell proliferation, abnormalities in the extracellular matrix and transepithelial fluid secretion. Multiple studies have suggested that fluid secretion across ADPKD ...

A survey of arsenic in the biosphere, involving analyses of substances by which man is exposed, has been made, using ashing at low temperatures and chemical methods. Arsenic was found in soils, most foods, many waters, almost all plants and plant products and in most animal tissues. Arsenic is ubiquitous in the biosphere, with a few exceptions. Data is included which show the amount of arsenic ...

The renin-angiotensin system (RAS), a key regulator of the blood pressure and fluid/electrolyte homeostasis, also plays a critical role in kidney development. All the components of the RAS are expressed in the developing metanephros. Moreover, mutations in the genes encoding components of the RAS in mice or humans are associated with a broad spectrum of ...

Body fluid homeostasis is critical for the survival of living organisms and hence is tightly controlled. From initial studies on the effects of secretin (SCT) on renal water reabsorption in the 1940s and recent investigations of its role in cardiovascular and neuroendocrine functions, it has now become increasingly clear that this peptide is an integral ...
The apelinergic system, comprised of apelin and its G protein-coupled receptor (APJ; APLNR as given in MGI Database), is expressed within key regions of the central nervous system associated with arginine vasopressin (AVP) synthesis and release as well as in structures involved in the control of drinking behaviour, including the magnocellular neurones of the hypothalamus, circumventricular organs, ...
Exposure to conditions of microgravity for any extended duration can modify the distribution of fluid within the vascular and interstitial spaces, and eventually intracellular volume. Whether the redistribution of fluid and resetting of volume homeostasis...
Vectorial ion flow across the alveolar epithelium provides the driving force for lung fluid secretion in the prenatal lung and for fluid reabsorption at birth and thereafter into adult life. Fluid secretion is dependent upon 'active' accumulation of Cl- into the lumen of the developing lung and any factor which interupts the production ...
Traumatic brain injury (TBI) survivors often suffer chronically from significant morbidity associated with cognitive deficits, behavioral difficulties and a post-traumatic syndrome and thus it is important to understand the pathophysiology of these long-term plasticity changes after TBI. Calcium (Ca2+) has been implicated in the pathophysiology of TBI-induced neuronal death ...
Na(v)2/NaG is a putative sodium channel, whose physiological role has long been an enigma. We generated Na(v)2 gene-deficient mice by inserting the lacZ gene. Analysis of the targeted mice allowed us to identify Na(v)2-producing cells by examining the lacZ expression. Besides in the lung, heart, dorsal root ganglia, and Schwann cells in the peripheral nervous system, Na(v)2 was expressed in ...

Male mice deficient in ESR1 (ERalpha) (Esr1KO mice) are infertile, and sperm recovered from the cauda epididymis exhibit reduced motility and fail to fertilize eggs in vitro. These effects on sperm appear to result from defective epididymal function and not a direct effect on spermatogenesis, as Esr1KO germ cells transplanted into wild-type testes yield normal offspring. We hypothesized that the ...

We studied the distribution of fluid using bioimpedance spectroscopy to determine if HD patients have an excess of ...

Besides the importance of the renin-angiotensin system (RAS) in the circulation and other organs, the local RAS in the kidney has attracted a great attention in research in last decades. The renal RAS plays an important role in the body fluid homeostasis and long-term cardiovascular regulation. All major components and key enzymes for the establishment of ...
Increasing evidence suggests that natriuretic peptides (NPs) play diverse roles in mammals, including renal hemodynamics, neuroendocrine, and cardiovascular functions. Collectively, NPs are classified as hypotensive hormones; the main actions of NPs are implicated in eliciting natriuretic, diuretic, steroidogenic, antiproliferative, and vasorelaxant effects, important factors in the control of ...
Hospice palliative care programs are rapidly growing in Japan.

Vasopressin plays a central role in regulating body fluid homeostasis, serum osmolality and vascular tone. In response to elevated serum osmolality, vasopressin acts on V2 renal receptors increasing water reabsorption and causing serum sodium to decrease. Pathological conditions characterized by abnormally elevated vasopressin levels ...
Juxtaglomerular cells are highly specialized myoepithelioid granulated cells located in the glomerular afferent arterioles. These cells synthesize and release renin, which distinguishes them from other cells. How these cells maintain their identity, restricted localization, and fate is unknown and is fundamental to the control of BP and homeostasis of ...
