introduction: during hemorrhagic shock (hs), the kidneys are one of the primary target organs involved. oxidative stress is shown to be enhanced in different models of acute kidney injury (aki). remote ischemic preconditioning (rpc) by brief limb ischemia is considered to be a safe method to protect different organs from further damage. in this study, we investigated the effects of brief hind l...

background serum creatinine as a classic marker of renal function has several limitations in the detection of renal dysfunction. objectives this study assessed the validity of serum cystatin c as a marker of renal function in critically ill patients with normal serum creatinine. patients and methods eighty adult patients referred to intensive care units with serum creatinine levels < 1.5 mg/dl ...

BACKGROUND The early/asymptomatic stages of heart failure (HF) are characterized by sodium retention secondary to derangement of sodium reabsorption at the proximal nephron level. Because this phenomenon is reversed by ACE inhibition, abnormalities of renal sodium handling may depend on intrarenal changes of angiotensin II (AII)/nitric oxide (NO) levels. Renal hemodynamic reserve (ie, the glome...

BACKGROUND AND OBJECTIVES This study had the purpose of studying gastric emptying in patients with chronic renal failure. MATERIAL AND METHOD Thirty patients with chronic renal failure were studied, 16 in conservative clinical treatment and 14 in hemodialysis for over six months. The control group (CTL) was composed of 18 asymptomatic volunteers. The method of gastric emptying study was scint...

Cirrhosis with ascites is associated with impaired renal function accompanied by sodium and water retention. Although it has been suggested thatmediators such as nitric oxide play a role in the development of renal failure in this situation, other mechanisms underlying the process are not well understood. This study examined the role of oxidative stress in mediating renal damage during the deve...

PURPOSE Children with myelomeningocele who leak with high intravesical pressures are at risk for upper urinary tract deterioration. Urodynamic study shortly after birth and routinely thereafter has been advocated to predict which newborns are at risk for upper tract deterioration. We hypothesize an approach that excludes routine application of urodynamic evaluation in neonates, reserving this s...

INTRODUCTION Renal Na+ retention and extracellular fluid volume expansion are hallmarks of nephrotic syndrome, which occurs even in the absence of activation of hormones that stimulate renal Na+ transporters. Plasmin-dependent activation of the epithelial Na+ channel (ENaC) has been proposed to have a role in renal Na+ retention in the setting of nephrotic syndrome. We hypothesized that the ENa...

an important property that has been extensively studied in quantitative structure activityrelationship (qsar) is the chromatographic retention index. qsar study is suggested for theprediction of retention index of alkanes and alkenes compounds. modeling of the retention indexof alkanes and alkenes compounds as a function of molecular structures was established bydifferent chemometrics methods. ...

Despite the ubiquitous use of both over-the-counter and prescription nonsteroidal anti-inflammatory drugs (NSAIDs), clinical syndromes—NSAID-related hypertension, salt and water retention, edema, and hyperkalemia—are highly infrequent. Nevertheless, they remain a concern, and patient populations at risk for renal adverse effects from NSAIDs can be prospectively identified. Patients at risk incl...

In the late stages of chronic renal damage the functional mass of the kidney is reduced and there is progression to renal insufficiency, usually called uremia, in which all aspects of renal function are affected. The complexity of the biochemical aspects of the syndrome of uremia is a manifestation of the wide variety and nature of the individual disorders that contribute to the pathogenesis of...
