1. Chronic kidney disease is a main confounding factor for 25-vitamin D measurement
Resumo Antecedentes: As diretrizes atuais recomendam a avaliação do estado da 25-hidroxivitamina D em pacientes com doença renal crônica (DRC). Embora significativas diferenças entre os ensaios tenham sido descritas, o impacto da nesta variabilidade DRC nunca foi testado. Métodos: Testamos a variabilidade entre dois ensaios de 25-hidroxivitamina D em

2. Issues in solid-organ transplantation in children: translational research from bench to bedside
In this review, we identify important challenges facing physicians responsible for renal and cardiac transplantation in children based on a review of the contemporary medical literature. Regarding pediatric renal transplantation, we discuss the challenge of antibody-mediated rejection, focusing on both acute and chronic antibody-mediated rejection. We review

3. Atividades antinociceptiva e antiinflamatÃria dos polissacarÃdeos sulfatados da alga marinha vermelha Gracilaria cornea J. Agardh / Antinociceptive and anti-inflammatory activities of sulfated polusaccharides from the red marine alga Gracilaria cornea J. Agardh (1852) in animals
Marine algae are natural sources of sulfated polysaccharides possessing several biological activities (anticoagulant, antithrombotic, antinociceptive, anti-inflammatory etc.) and that exhibit minimal toxicity and are considered of great interest to the pharmaceutical and food industries. This study aimed to evaluate the effects of sulfated polysaccharides to

4. Renal and vascular effects of Crotalus durissus cumanensis venom and its crotoxin fraction
In this study, we evaluated the actions of Crotalus durissus cumanensis venom (CDCmV), and its crotoxin (Crtx) fraction, on renal and vascular functions in Wistar rats. In isolated perfused kidneys, CDCmV (10 µg/mL) significantly increased the perfusion pressure (PP) from 110.7 ± 2.4 to 125.3 ± 2.8 mmHg after 30 minutes. This effect was accompanied by an

5. Comparison of non-invasive methods for the detection of coronary atherosclerosis
BACKGROUND: Non-invasive detection of atherosclerosis is critical for its prevention. OBJECTIVE: To correlate non-invasively detectable indicators of coronary atherosclerosis, or Coronary Artery Disease (i.e., classical risk factors, hs-CRP test results, carotid intima-media thickness, endothelial function, ankle-brachial index and calcium score by computed

6. Biological effects induced by Tityus serrulatus crude venom and its toxins TsTx-V, gamma toxin and natriuretic peptide / Efeitos biolÃgicos induzidos pelo veneno total de Tityus serrulatus e suas fraÃÃes TsTx-V, toxina gama e peptÃdeo natriurÃtico
The venom of Tityus serrulatus has a mixture of toxic and non toxic peptides presenting diverse systemic and local effects. The aim of this work was to investigate the cardiovascular and renal effects promoted by the crude venom of the scorpion Tityus serrulatus and its isolated components such as Tityus serrulatus toxin V (TsTx-V), Gamma Toxin and the newly

7. PRECONDITIONING OF ORGAN DONORS WITH LOW LEVELS OF CARBON MONOXIDE REDUCES GRAFT IMMUNOGENICITY AND IMPROVES LONGTERM ALLOGRAFT FUNCTION
Background: Chronic rejection remains the major obstacle for successful transplantation, and to date there is no effective treatment. Events occurring prior to organ transplantation such as brain death, harvesting procedure, and ischemia-reperfusion injury lead to unspecific inflammatory damages danger signals - that increase graft immunogenicity and reduce

8. Biochemical and histologic findings in experimental pyelonephritis due to Ureaplasma urealyticum.
Ureaplasma urealyticum has previously been shown to be capable of persisting in the rat kidney for up to 6 months following a single reflux challenge. We examined kidney tissue from infected animals for evidence of renal damage by using standard cytochemical and immunoenzyme methods. We also monitored changes in renal function during a 6-month study period w

9. Pharmacokinetics of meropenem (ICI 194,660) and its metabolite (ICI 213,689) in healthy subjects and in patients with renal impairment.
The pharmacokinetics of meropenem (ICI 194,660) and its open-ring metabolite (ICI 213,689) were studied in 6 healthy volunteers and 16 patients with moderate to severe renal impairment after a single intravenous dose of 500 mg given as a 30-min infusion. Concentrations of unchanged meropenem in plasma and urine were measured by both microbiological and high-

10. Absence of angiotensin II type 1 receptor in bone marrow–derived cells is detrimental in the evolution of renal fibrosis
We examined the in vivo function of the angiotensin II type 1 receptor (Agtr1) on macrophages in renal fibrosis. Fourteen days after the induction of unilateral ureteral obstruction (UUO), wild-type mice reconstituted with marrow lacking the Agtr1 gene (Agtr1–/–) developed more severe interstitial fibrosis with fewer interstitial macrophages than those i

11. Regulation of angiotensin II receptor AT1 subtypes in renal afferent arterioles during chronic changes in sodium diet.
Studies determined the effects of chronic changes in sodium diet on the expression, regulation, and function of different angiotensin II (ANG II) receptor subtypes in renal resistance vessels. Rats were fed low- or high-sodium diets for 3 wk before study. Receptor function was assessed in vivo by measuring transient renal blood flow responses to bolus inject

12. Glomerulonephritis mediated by antibody to glomerular basement membrane. Immunological, clinical, and histopathological characteristics.
A prospective study was undertaken to establish the incidence of glomerular basement membrane (GBM) antibody-mediated glomerulonephritis and its histopathological characteristics in a clinical group of patients presenting with renal disease. Biopsies from 43 of 409 consecutive patients technically satisfactory for direct immunofluorescent (IF) examination ha
