Klotho urinario determinado por ELISA como biomarcador precoz de fracaso renal agudo en pacientes sometidos a cirugía cardiaca o angiografía coronaria
2015
ResumenIntroducción y objetivos: El fracaso renal agudo (FRA) es una complicación frecuente tras la cirugía cardiaca y las intervenciones percutáneas coronarias cuya aparición empeora el pronóstico de manera marcada. En los últimos años se han identificado nuevos biomarcadores precoces de FRA, pero aún quedan muchos aspectos importantes por resolver. Klotho es una proteína pleiotrópica que actúa como un factor paracrino y endocrino en múltiples órganos. En diversos modelos animales de FRA se ha demostrado niveles disminuidos de Klotho renal. No se ha publicado ningún estudio en el que se haya probado Klotho como marcador precoz de FRA en humanos. El objetivo de este trabajo es investigar la…
256 Functional analysis of elective nephron-sparing surgery versus radical nephrectomy for renal tumors larger than 4 cm
2012
Objective To preserve renal function, nephron sparing surgery (NSS) for renal tumors should be performed. Little is known about perioperative morbidity and long-term functional outcome of patients after elective NSS compared with radical nephrectomy (RN) in renal tumors >4 cm. Materials and Methods Eight-hundred twenty-nine patients were treated with either RN (n = 641) or NSS (n = 188) for renal tumors >4 cm. After pairing the cohort for age, grading, TNM, size, gender, and preoperative renal function and excluding patients with imperative indication and metastases, 247 patients remained for functional analysis. Serum creatinine (SCr) values were used to estimate glomerular filtration rate…
Prognostic Significance of Histopathological Grading and Immunoreactivity for p53 and p21/WAF1 in Grade 2 pTa Transitional Cell Carcinoma of …
2001
At present, there are no predictors of tumour behaviour for grade (G) 2 pTa transitional cell carcinomas (TCC) of the bladder. Here we analyse the prognostic relevance of histopathological grading and the immunohistochemical detection of p53 and p21/WAF1.70 patients were newly diagnosed with G2 pTa TCC of the bladder based on transurethral resection specimens. Two pathologists, blinded with respect to the clinical outcome, confirmed the initial grade and subclassified the G2 lesions into G2a and G2b carcinomas based on the degree of nuclear atypia and the number of mitoses. Immunoreactivity for p53 and p21/WAF1 was evaluated semiquantitatively.There were 52 G2a and 18 G2b tumours, mean foll…

Mechanical and electrophysiological effects of cromakalim on the human urinary bladder.
1994
The effects of cromakalim on spontaneous and induced mechanical activity of human detrusor muscle were investigated in vitro. Cromakalim produces a concentration-related decrease of spontaneous as well as carbachol- and K(+)-evoked contractions. This is the first study to utilize the patch clamp technique to elucidate the mechanism of action of cromakalim on human detrusor cells. Cromakalim hyperpolarizes the detrusor cells by increasing the net outward current which is most likely carried by potassium ions. In the human urinary bladder, this effect is mediated by a glibenclamide-sensitive potassium channel, as glibenclamide is able to diminish the relaxant effect of cromakalim and to preve…
Late results of bladder stimulation in 11 patients: followup to 4 years.
1978
Abstract Direct stimulation of the detrusor muscle offers the best possibility to evacuate the bladder in highly selected patients. During the last 4 years 11 patients have undergone implantation of a bladder pacemaker. Followup revealed that 1 patient could void only during stimulation, while 7 patients had reflex evacuation and 3 had no function at all. An exceptional case report is presented.
MODULATION OF BLADDER α1-ADRENERGIC RECEPTOR SUBTYPE EXPRESSION BY BLADDER OUTLET OBSTRUCTION
2002
Purpose: α1-Adrenergic receptor (α1AR) antagonists are effective for relieving obstructive and irritative symptoms in patients with bladder outlet obstruction. While the α1aAR is responsible for prostate smooth muscle relaxation and outlet obstruction relief, to our knowledge the mechanisms underlying the relief of irritative symptoms remain to be determined. Therefore, we investigated mechanisms by which bladder α1AR subtypes may be involved in this process.Materials and Methods: We studied 42 rats, including 6 unoperated controls, 17 sham operated controls and 19 obstructed animals. Animals were characterized for baseline voiding pattern, followed by surgical intervention or sham surgery …
Hybrid Chelator-Based PSMA Radiopharmaceuticals: Translational Approach
2021
(1) Background: Prostate-specific membrane antigen (PSMA) has been extensively studied in the last decade. It became a promising biological target in the diagnosis and therapy of PSMA-expressing cancer diseases. Although there are several radiolabeled PSMA inhibitors available, the search for new compounds with improved pharmacokinetic properties and simplified synthesis is still ongoing. In this study, we developed PSMA ligands with two different hybrid chelators and a modified linker. Both compounds have displayed a promising pharmacokinetic profile. (2) Methods: DATA5m.SA.KuE and AAZTA5.SA.KuE were synthesized. DATA5m.SA.KuE was labeled with gallium-68 and radiochemical yields of various…
Identification of fatty acid binding proteins as markers associated with the initiation and/or progression of renal cell carcinoma
2005
Renal cell carcinoma (RCC) representing the most common neoplasia of the kidney in Western countries is a histologic diverse disease with an often unpredictable course. The prognosis of RCC is worsened with the onset of metastasis, and the therapies currently available are of limited success for the treatment of metastatic RCC. Although gene expression analyses and other methods are promising tools clarifying and standardizing the pathological classification of RCC, novel innovative molecular markers for the diagnosis, prognosis, and for the monitoring of this disease during therapy as well as potential therapeutic targets are urgently needed. Using proteome-based strategies, a number of RC…
