La delimitación del concepto de daño moral: un estudio de la cuestión en el ordenamiento jurídico español.
2021
El presente estudio tiene como objetivo realizar una aproximación al concepto de daño moral en el derecho español porque, a diferencia del daño patrimonial, el Código Civil no proporciona un concepto sobre él. Para la articulación de un concepto de daño moral es necesario analizar los supuestos de reconocimiento legal, la interpretación que los órganos judiciales han hecho y el tratamiento proporcionado en los Principios de derecho contractual europeo y de derecho de daños europeo. El trabajo finaliza con una valoración sobre la actual configuración del daño moral. The present study aims to make an approximation to the concept of non-pecuniary damage in Spanish law because, unlike property …
Genesi geometrica delle volte centriche
1996
Un'analisi completa degli organismi voltati comporta lo studio delle molteplici componenti necessarie alla loro definizione: configurazione geometrica, sistema costruttivo, area storico-geografica di appartenenza, interpretazioni Stilistiche. L’obiettivo di questo studio è indirizzato all' analisi delle volte continue su pianta centrica definibili attraverso le leggi della geometria euclidea. L’indagine si pone all'interno dei confini relativi alla loro configurazione geometrica e il criterio adottato, svincolato da classificazioni di carattere tipologico o stilistico, propone l'identificazione di famiglie geometriche in base alla figura del poligono di base dell'impianto. Si può identifica…
Respiratory involvement in antineutrophil cytoplasmic antibody-associated vasculitides: a retrospective study based on POLVAS registry
2021
OBJECTIVES: The study aimed to characterise the Polish population of (ANCA)-associated vasculitides (AAV) with respiratory involvement (RI), in comparison to the subgroup without lung manifestations and the other cohorts. METHODS: Retrospective analysis of the Polish population of AAV with RI was conducted, based on data from the POLVAS registry. Standard descriptive statistics, χ2 test, and Mann-Whitney U test were used to perform comparisons. RESULTS: Among 461 cases qualified to this study, there were 316 cases with RI (68.5%), 206 with granulomatosis with polyangiitis (GPA) (65.2%), 80 with eosinophilic granulomatosis with polyangiitis (EGPA) (25.3%) and 30 with microscopic polyangiitis…
Relief of microRNA-Mediated Translational Repression in Human Cells Subjected to Stress
2006
SummaryIn metazoans, most microRNAs imperfectly base-pair with the 3′ untranslated region (3′UTR) of target mRNAs and prevent protein accumulation by either repressing translation or inducing mRNA degradation. Examples of specific mRNAs undergoing microRNA-mediated repression are numerous, but whether the repression is a reversible process remains largely unknown. Here we show that cationic amino acid transporter 1 (CAT-1) mRNA and reporters bearing its 3′UTR can be relieved from the microRNA miR-122-induced inhibition in human hepatocarcinoma cells subjected to different stress conditions. The derepression of CAT-1 mRNA is accompanied by its release from cytoplasmic processing bodies and i…
Maternal transfer of antibodies: raising immuno-ecology issues.
2007
The transfer of antibodies from mother to offspring has broad potential implications in evolutionary ecology, from the adaptive value of maternal effects to the role of transgenerational plasticity in host-parasite interactions. Recent contributions have addressed key issues such as environmental and genetic factors affecting the amount of antibodies transferred and whether maternal antibodies affect offspring immunity, but little is still known about the implications of the maternal transfer of antibodies in natural populations. By its position at the crossroads between population ecology, animal science, medicine and epidemiology, current studies of the role of the maternal transfer of an…
Expression of glial filament protein (GFP) in nerve sheaths and non-neural cells re-examined using monoclonal antibodies, with special emphasis on th…
1986
We describe two novel monoclonal antibodies specific for glial filament protein (GFP), i.e., GF12.23 and GF12.24 (both IgG2a]. These cross-react over a broad range of species with epitopes located in the alpha-helical rod domain typical of all intermediate filament (IF) proteins. These monoclonal antibodies were used, in conjunction with other monoclonal GFP antibodies, rabbit antiserum to GFP, and various antibodies to other cytoskeletal proteins, to examine the occurrence of GFP in cells outside of the central nervous system of rodents, cows, and humans. We detected some scattered GFP-containing cells in the neural sheaths in some species but not in others, and we obtained different resul…
Immunolocalization of integrins in the normal and neoplastic colonic epithelium.
1993
Cryosections of normal colon (NC), tubular and villous adenomas (TA, VA), and variably differentiated colon adenocarcinomas (CA) were immunostained with monoclonal antibodies to alpha 1-6 and alpha v, and beta 1-4 integrin subunits; select samples were stained for cytokeratin (Ck) 20 and villin. In NC, alpha 2 staining was strongest in crypt cells; alpha 1,3 and alpha v, and beta 1,3 and beta 4, and Ck 20 and villin predominated in superficial enterocytes. In TA and VA, monolayered glands showed integrin, Ck 20 and villin patterns that differed slightly from both crypt and superficial enterocytes. Complex glands in VA showed decreased integrin staining and basal polarization; Ck 20 and vill…
Epithelial markers and differentiation in adnexal neoplasms of the skin: an immunohistochemical study including individual cytokeratins
1995
Applying immunohistochemical procedures for the detection of eight different cytokeratin (CK) polypeptides and other differentiation markers, we compared the staining patterns of normal cutaneous structures with those of benign adnexal tumors (n = 65). Syringomas exhibited a marker pattern highly reminiscent of that seen in normal dermal eccrine ducts (EMA in peripheral cells, CK 10 in intermediate cells, and CK 6, CK 19, and CEA in luminal cells). Nodular hidradenomas exhibited complex patterns suggesting relationship between tumor cells, including clear cells, and normal secretory coil cells (CK 7, CK 8, CK 19, and EMA); however, dermal-duct and epidermoid differentiation were also detect…
Immunoperoxidase Staining of Fine-Needle Aspiration Biopsies of Renal Cell Carcinoma Using Tumor-Specific Monoclonal Antibody
1987
In 30 nephrectomy specimens, fine needle aspiration biopsies (FNAB) were performed both in the tumor and in the macroscopically normal part of the kidney: 18 were well differentiated renal cell carcinoma (RCC), 6 were moderately differentiated RCC, 4 were poorly differentiated RCC, and 2 were oncocytomas. FNAB was also performed in a bone metastasis of RCC. FNAB materials were stained using the immunoperoxidase method with RCC-specific monoclonal antibody and were compared with the staining of frozen sections. In all cases where tumor-antigen expression could be demonstrated in the frozen sections, a FNAB had already proven positive. There were only 2 false-negative cases where sufficient c…
Use of the polymerase chain reaction to demonstrate hepatitis B virus DNA in serum of children with chronic hepatitis B.
1992
The polymerase chain reaction was used to investigate the presence of hepatitis B virus DNA in sera of 61 children with chronic hepatitis B and negative results on dot biot hybridization tests. Our results demonstrate that most chronic carriers of hepatitis B surface antigen in childhood have hepatitis B virus DNA detectable by polymerase chain reaction in their serum and must be considered infectious.
