Therapeutic Modulation of Urinary Bladder Function: Multiple Targets at Multiple Levels
2015
Storage dysfunction of the urinary bladder, specifically overactive bladder syndrome, is a condition that occurs frequently in the general population. Historically, pathophysiological and treatment concepts related to overactive bladder have focused on smooth muscle cells. Although these are the central effector, numerous anatomic structures are involved in their regulation, including the urothelium, afferent and efferent nerves, and the central nervous system. Each of these structures involves receptors for—and the urothelium itself also releases—many mediators. Moreover, hypoperfusion, hypertrophy, and fibrosis can affect bladder function. Established treatments such as muscarinic antago…
Generation of a DNA microarray for determination of E6 natural variants of human papillomavirus type 16.
2003
Infection with high-risk types of human papillomavirus (HPV) is necessary for the development of cervical cancer. However, the majority of the HPV infections are efficiently cleared by the immune system and only a minority persist and induce the development of malignant lesions. Several studies provided evidence that intratype genetic variations are implicated in determining the clinical outcome of HPV infections. In this study, we describe a DNA chip based on arrayed primer extension (APEX) for the analysis of the natural variants of HPV16, the most frequently detected type in cervical cancer world-wide. We show that HPV16 E6 variants are detected efficiently by APEX. In addition, APEX is …
Serological evidence for protection by human papillomavirus (HPV) type 6 infection against HPV type 16 cervical carcinogenesis
1999
Human papillomavirus (HPV) exists as more than 100 genotypes. It is not well-established whether the different HPV types interfere with infection or pathogenesis by each other. Possible interactions in cervical carcinogenesis between infection with the most common HPV types (6, 11, 16, 18 and 33) were studied in a seroepidemiological case- control study of 218 women with primary untreated cervical cancer and 219 healthy age-matched control women. As previously shown, HPV-16 seropositivity was associated with cervical cancer risk [odds ratio (OR), 2·39], but HPV-16 was not associated with cervical cancer risk among HPV-6 seropositive women (OR, 1·0). The relative excess risk due to interacti…
Infecciones por clamidias
2007
Las clamidias son un grupo peculiar de bacterias, cuyo ciclo vital transcurre en parte en el interior de las células. Tienen la propiedad de adherirse a determinados epitelios, en los que pueden acabar produciendo infecciones. Existen tres especies patógenas para el hombre: Chlamydia trachomatis, que produce infecciones fundamentalmente en los epitelios genital y urinario, y C. psittaci y C. pneumoniae, que producen fundamentalmente infecciones respiratorias. A las dos últimas se les clasifica en la actualidad en un género diferente, el de las Chlamydophilas.
Effects of sleep apnea and kidney dysfunction on objective sleep quality in nondialyzed patients with chronic kidney disease: an ESADA study
2020
Study Objectives: Patients with chronic kidney disease (CKD) often report poor sleep quality, but they commonly exhibit OSA. The aim of this study was to evaluate the influence of OSA severity and of estimated glomerular filtration rate impairment on objective sleep quality in nondialyzed patients with CKD, defined as an estimated glomerular filtration rate <60 mL/min/1.73m2. Methods: Polysomnographic sleep characteristics were compared between patients with (n = 430) and without CKD (n = 6,639) in the European Sleep Apnea Database cohort. Comparisons were repeated in 375 patients with CKD and 375 control patients without CKD matched for sleep center, age, sex, and AHI, and in 310 matche…
Retarding Chronic Kidney Disease (CKD) Progression: A Practical Nutritional Approach for Non-Dialysis CKD
2016
This is a case report on a patient with non-dialysis chronic kidney disease (CKD) in whom several nutritional issues are briefly discussed from a practical point of view. The article is accompanied by an editorial published in this Journal in relation to the 2nd International Conference of the European Renal Nutrition working group at ERA-EDTA—“Retarding CKD progression: readily available through comprehensive nutritional management?”— and focuses on several practical topics associated with the nutritional approach for the conservative treatment of non-dialysis CKD. The article is divided into 3 sections—basic nutritional assessment, nutritional targets, and nutritional follow-up in non-di…
mdm2 mRNA expression is associated with survival in ovarian cancer
1997
Expression of mdm-2 mRNA was measured in 90 ovarian-cancer tissue specimens using the S1 nuclease assay, to investigate a possible association between MDM2 expression and prognosis. mdm-2 mRNA expression was an independent prognostic factor for patients with primary ovarian cancer, FIGO (International Federation of Gynecology and Obstetrics) stages III and IV (n = 57), who all received chemotherapy with carboplatin or cisplatin and cyclophosphamide. Median survival time for patients (FIGO stages III and IV) with no detectable expression of mdm-2 mRNA (n = 14) was 171 days, as compared with 839 days for patients (n = 43) with detectable mdm-2 mRNA (p = 0.0194; log-rank test). However, no ass…
Anticancer platinum agents and light
2019
Abstract Since the discovery of cisplatin, light activation has been employed as a strategy to switch and improve the anticancer effects of platinum compounds. This contribution highlights some of the most representative discoveries obtained in the field of platinum-based photochemotherapy over the years.
Genome-Wide Association Study of Diabetic Kidney Disease Highlights Biology Involved in Glomerular Basement Membrane Collagen
2019
BACKGROUND: Although diabetic kidney disease demonstrates both familial clustering and single nucleotide polymorphism heritability, the specific genetic factors influencing risk remain largely unknown.METHODS: To identify genetic variants predisposing to diabetic kidney disease, we performed genome-wide association study (GWAS) analyses. Through collaboration with the Diabetes Nephropathy Collaborative Research Initiative, we assembled a large collection of type 1 diabetes cohorts with harmonized diabetic kidney disease phenotypes. We used a spectrum of ten diabetic kidney disease definitions based on albuminuria and renal function.RESULTS: Our GWAS meta-analysis included association result…
Evidence for the presence of autoantibodies to the collagen-like portion of C1q in systemic lupus erythematosus.
1988
We investigated the connection between the C1q solid-phase binding assay (C1q SPBA) and double-stranded DNA antibodies, and analyzed the immune complex material in systemic lupus erythematosus (SLE) sera. Comparison with a new monoclonal assay for C1q-bearing immune complexes (the 242G3 assay) revealed that the immune complexes in SLE bind specifically to solid-phase C1q, and not to fluid-phase C1q. The C1q solid-phase binding activity sedimented as 7S IgG, was insensitive to DNase treatment, and could be selectively absorbed by C1q-coupled beads and by bovine serum albumin-anti-bovine serum albumin C1q beads, but not by DNA. Thus, antibodies to double-stranded DNA do not interfere in the C…
