Modified seromuscular tube: serosa lined bowel wall imbrication as a continent outlet for continent cutaneous urinary diversion.

1999

Purpose: We created a simplified modification of the seromuscular tube technique for continent cutaneous urinary diversion. Materials and Methods: We applied a simplified modification of our seromuscular tube technique in 1 woman and 2 men with a mean age of 53 years in whom outlet failure developed after continent cutaneous urinary diversion, and in whom adiposity and postoperative adhesions rendered revision difficult. We constructed a continent outlet conduit by imbricating the whole bowel wall and suturing it into a tube. Results: At a followup of 4 to 13 months (mean 7) all 3 patients are completely continent without leakage. Catheterization is performed at 3 to 5-hour intervals (mean …

Meta-analysis of genome-wide linkage scans of attention deficit hyperactivity disorder

2008

Contains fulltext : 69243.pdf (Publisher’s version ) (Closed access) Genetic contribution to the development of attention deficit hyperactivity disorder (ADHD) is well established. Seven independent genome-wide linkage scans have been performed to map loci that increase the risk for ADHD. Although significant linkage signals were identified in some of the studies, there has been limited replications between the various independent datasets. The current study gathered the results from all seven of the ADHD linkage scans and performed a Genome Scan Meta Analysis (GSMA) to identify the genomic region with most consistent linkage evidence across the studies. Genome-wide significant linkage (P(S…

Identification and characterization of novel associations in the CASP8/ALS2CR12 region on chromosome 2 with breast cancer risk.

2014

Previous studies have suggested that polymorphisms in CASP8 on chromosome 2 are associated with breast cancer risk. To clarify the role of CASP8 in breast cancer susceptibility, we carried out dense genotyping of this region in the Breast Cancer Association Consortium (BCAC). Single-nucleotide polymorphisms (SNPs) spanning a 1 Mb region around CASP8 were genotyped in 46 450 breast cancer cases and 42 600 controls of European origin from 41 studies participating in the BCAC as part of a custom genotyping array experiment (iCOGS). Missing genotypes and SNPs were imputed and, after quality exclusions, 501 typed and 1232 imputed SNPs were included in logistic regressionmodels adjusting for stud…

Sondeo de l'Albufera de Pego (Valencia): micropaleontología y biofacies

1988

LA ANTIGUA ALBUFERA DE PEGO (VALENCIA-ESPAÑA) ES UN INTERESANTE PALEOSISTEMA DONDE LAS BIOFACIES REGISTRAN UNA HIDRODINAMICA SEDIMENTARIA DE ORIGEN MIXTO O PARALICO. EL GRADO DE INCIDENCIA Y ANTAGONISMO DE LAS AGUAS CONTINENTALES Y MARINAS QUEDA REGISTRADO EN FORAMINIFEROS, OSTRACODOS, MICROMOLUSCOS Y RESTOS VEGETALES, CUYA EVOLUCION CUANTITATIVA Y MORFOLOGICA, A TRAVES DEL SONDEO, REFLEJA NO SOLO EL GRADO DE EURIHALINIDAD DE LOS ORGANISMOS, SINO TAMBIEN LOS DIVERSOS EPISODIOS LITORALES DEL WURM II-III HASTA EL HOLOCENO, PASANDO POR LA TRANSGRESION FLANDRIENSE.

Geohazard assessment of the north-eastern Sicily continental margin (SW Mediterranean): coastal erosion, sea-level rise and retrogressive canyon head…

2022

Coastal dynamics are the result of several processes controlling the balance between sediment input and output over time. The beach system is not always able to maintain a neutral coastal balance due to natural and anthropogenic causes. We present an integrated marine geology, geomorphological and sea-level rise analysis in the coastal sector between Torre delle Ciavole and Capo Calavà (North-Eastern Sicily, Italy).This sector is characterized by high uplift rates and frequent seismicity (mainly generated by the very active Vulcano-Tindari Fault System), promoting the development of mass-wasting processes in the coastal and offshore sectors. A main erosive feature observed in the area is th…

Síntesis de los estudios sobre moluscos continentales neógenos del sector septentrional de la Depresión de Teruel: período 1775-1998

2006

Se recopila y analiza la información que se considera más relevante y se encuentra contenida en los estudios realizados sobre el registro fósil de los moluscos neógenos del sector septentrional de la Depresión de Teruel en el período comprendido entre los años 1775 y 1998. Se contabilizan, por una parte, el número total de taxones diferentes mencionados en cada trabajo y, por otra, sólo el número de citas efectuadas a nivel de especie en cada uno de ellos. Estas últimas se organizan en tres categorías que reciben el nombre de citas nuevas, especies nuevas y citas repetidas. Se propone, a partir de la información contenida en cada trabajo, el número de taxones contemplados, y la tipología de…

Ancient human genomes suggest three ancestral populations for present-day Europeans

2014

We sequenced the genomes of a ∼7,000-year-old farmer from Germany and eight ∼8,000-year-old hunter-gatherers from Luxembourg and Sweden. We analysed these and other ancient genomes1,2,3,4 with 2,345 contemporary humans to show that most present-day Europeans derive from at least three highly differentiated populations: west European hunter-gatherers, who contributed ancestry to all Europeans but not to Near Easterners; ancient north Eurasians related to Upper Palaeolithic Siberians3, who contributed to both Europeans and Near Easterners; and early European farmers, who were mainly of Near Eastern origin but also harboured west European hunter-gatherer related ancestry. We model these popula…

Analyses of phase change materials’ efficiency in warm-summer humid continental climate conditions

2017

The usage of phase change materials (PCMs) is a way to store excess energy pro- duced during the hot time of the day and release it during the night thereby reducing the overheating problem. While, in Latvian climate conditions overheating is not a big issue in traditional buildings since it happens only a couple of weeks per year air conditioners must still be installed to maintain thermal comfort. The need for cooling in recently built office buildings with large window area can increase signi cantly. It is therefore of great interest if the ther- mal comfort conditions can be maintained by PCMs alone or with reduced maximum power of installed cooling systems. Our initial studies show tha…

Experimental testing of phase change materials in a warm-summer humid continental climate

2019

Abstract The construction industry (and buildings) is one of the largest energy consuming and CO2 emitting sectors in the world. To counter this, more lightweight structures are being used and energy saving applications are being developed. Phase change materials (PCM) are materials that can be considered to tackle these new challenges. It has been proven that PCMs can be passively used to improve the thermal mass of lightweight structures, which improves thermal comfort and reduces peak cooling and heating loads and therefore provides energy savings. To use these materials in an active way, they should be used together with ventilation, cooling or heating equipment, and collectors to accum…
