Small-scale patches of detritus as habitat for invertebrates within a Zostera noltei meadow
2021
Abstract Seagrass detritus can attract numerous invertebrates as it provides food and substrate within the meadow or in adjacent environments. Nonetheless, several factors could modify the invertebrate response to this habitat. In this study, we tested if epifaunal colonisation of Zostera noltei detritus was related to substrate availability rather than food and whether colonising assemblages were similar according to the meadow structural complexity. Litterbags filled with natural or artificial detritus were deployed within an eelgrass meadow in a Mediterranean coastal lagoon (Thau lagoon, France). Colonisation appeared to be driven by the presence of detritus, with similar assemblages in …
A quantitative structural and morphometric analysis of the Purkinje network and the Purkinje-myocardial junctions in pig hearts
2017
The morpho-functional properties of the distal section of the cardiac Purkinje network (PN) and the Purkinje-myocardial junctions (PMJs) are fundamental to understanding the sequence of electrical activation in the heart. The overall structure of the system has already been described, and several computational models have been developed to gain insight into its involvement in cardiac arrhythmias or its interaction with implantable devices, such as pacemakers. However, anatomical descriptions of the PN in the literature have not enabled enough improvements in the accuracy of anatomical-based electrophysiological simulations of the PN in 3D hearts models. In this work, we study the global dis…
Worldwide comparison of ovarian cancer survival: Histological group and stage at diagnosis (CONCORD-2)
2016
Abstract Objective Ovarian cancer comprises several histological groups with widely differing levels of survival. We aimed to explore international variation in survival for each group to help interpret international differences in survival from all ovarian cancers combined. We also examined differences in stage-specific survival. Methods The CONCORD programme is the largest population-based study of global trends in cancer survival, including data from 60 countries for 695,932 women (aged 15–99years) diagnosed with ovarian cancer during 1995–2009. We defined six histological groups: type I epithelial, type II epithelial, germ cell, sex cord-stromal, other specific non-epithelial and non-sp…
Equality by reason of filiation and succession law
2019
El principio constitucional de igualdad en la filiación juega solamente en relación con sucesiones abiertas con posterioridad a la entrada en vigor de la constitución. Se examina la jurisprudencia más reciente sobre la materia. The constitutional principle of equality of filiation only applies to successions opened after the entry into force of the constitution. The paper reviews the most recent case law on the subject.
Correlation between GP-170 expression, prognosis, and chemoresistance of superficial bladder carcinoma.
2003
To study GP-170 in superficial bladder cancer at initial diagnosis and at recurrence and to evaluate if intravesical chemoprophylaxis modifies the expression of GP-170 in tumor recurrences. GP-170 was retrospectively assessed in 160 patients affected by primary superficial transitional cell carcinoma of the bladder and followed for up to 10 years. Eighty-four patients (52.5%) recurred after transurethral resection (TUR). Adjuvant intravesical chemotherapy after TUR was adopted in 52 patients. The correlations between GP-170 and G-grade, T-category, risk of recurrence and of progression, and adoption of adjuvant intravesical chemotherapy were investigated. The correlations between variations…
p53 immunoreactivity in biopsy specimens of T1G3 transitional cell carcinoma of the bladder--a helpful parameter in guiding the decision for or again…
2000
The aim of this study was to determine whether p53 is helpful in making the decision to undergo cystectomy in T1, G3 transitional cell carcinoma (TCC) of the bladder, by prospectively comparing the p53 status of bladder biopsies with the histology and p53 status of the corresponding cystectomy specimens. From January 1996 to August 1997, 38 consecutive patients with T1G3 TCC at 6 different centres were enrolled into the study. Bladder biopsies and cystectomy specimens were examined with three different antibodies against p53. The p53 status of each bladder biopsy was compared with p53 status, tumour stage and grade of the cystectomy specimen. An independent evaluation of the histology and i…
Facilitating holistic continuity of care for older patients: Home care nurses' experiences using checklists.
2019
Aims and objectives To explore home care nurses' experiences of implementation and use of checklists developed for improving continuity of care for older patients (65+ years). Background The Norwegian Coordination Reform was implemented to improve coordination between hospitals and communities and facilitate a quicker return to home community after hospital discharge. To follow-up, national learning networks were initialised to improve pathways for chronically ill older patients, including the development and use of standardised checklists. Design An explorative qualitative design was chosen. Methods Three focus group interviews were conducted, including 18 registered nurses from eight muni…
Factors affecting recurrence and progression in superficial bladder tumours
1995
Prognostic factors in superficial bladder tumours are highly correlated with each other. In this study, their relative importance is examined and grouping of patients in three different prognostic groups suggested. 576 patients (from EORTC protocols 30790 and 30782) were analysed. They have been followed from 3 months to 8.6 years with a median of 4 years. 76 patients developed an invasive tumour (or = T2); the shortest time to invasion was 12 weeks, the longest was 6.6 years. Time from invasion to death ranged from 3 weeks to 4.4 years with a median of 2 years. Prognostic factors contributing to recurrence, invasion and survival were investigated: age, sex, size of largest tumour, number o…
Cigarette Smoking and Drinking Water Source: Correlation with Clinical Features and Pathology of Superficial Bladder Carcinoma
2007
<i>Objective:</i> Water source and cigarette smoking are related to clinical characteristics and pathology of superficial transitional cell carcinoma of the bladder. <i>Methods:</i> Tumor number, dimension, G-grade, T-stage, recurrences, cigarette smoking and water supply were recorded in patients harboring Ta–T1 G1–3 transitional cell carcinoma of the bladder. <i>Results:</i> Of 577 patients, 61% had multiple and 36% recurrent tumors. Two hundred and forty-one patients (42%) were current smokers and 188 (33%) were former smokers. Bottled water was the only drinkable source for 249 (45%) patients, municipal water supply for 177 (32%), artesian wells for 3…
Behavior of Epithelial Differentiation Antigens (Carcinoembryonic Antigen, Epithelial Membrane Antigen, Keratin and Cytokeratin) in Transitional Cell…
1992
Results of an immunohistochemical study in normal urothelium and transitional cell carcinomas of the bladder are presented. Paraffin-embedded material was confronted with immunoantisera against carcinoembryonic antigen (CEA), keratin (K), cytokeratin (CK) and epithelial membrane antigen (EMA). Immunohistochemical findings confirm the changes in reactivity of dysplastic urothelium and carcinoma in situ for CEA, CK and EMA, in comparison with normal urothelium. Statistically significant differences were also found, depending upon tumor stage, in staining of transitional cell carcinomas for K and CK. Expression of CK correlated with the tumor differentiation grade: normal urothelium and well-d…
