Extraction socket preservation using porcine-derived collagen membrane alone or associated with porcine-derived bone. Clinical results of randomized controlled study

The aim of present randomized controlled clinical trial was to clinically evaluate hard tissue changes after extraction socket preservation procedures compared to natural spontaneous healing

Histologic evaluation of bone healing of adjacent alveolar sockets grafted with bovine- and porcine-derived bone: a comparative case report in humans

To evaluate and compare histomorphometrically the bone response to two xenografts, one bovine and the other porcine, grafted in adjacent extraction sockets in a human. In this case report, two adjacent maxillary premolars were extracted, and the sockets were filled with two different xenogeneic bone substitutes (first premolar with bovine bone, and second premolar with porcine bone) to counteract post-extraction volume loss. Following 6 months bone core specimens were harvested during the placement of implants at the regenerated sites. Histomorphometrically, for the bovine xenograft the percentage of newly formed bone (osteoid) was 26.85%, the percentage of the residual graft material was 17.2% and the percentage of connective tissue 48.73%, while for the porcine xenograft, newly formed bone (osteoid) represented 32.19%, residual graft material was 6.57% and non-mineralized connective tissue was 52.99%. Histological results indicated that both biomaterials assessed in this study as grafts for socket preservation technique are biocompatible and osteoconductive. Bovine bone derived demonstrated to be less resorbable than porcine bone derived. Both xenogenic biomaterials did not interfere with the normal bone reparative processe

ASSESSMENT OF THE TOTAL SOLIDS AND FAT CONTENTS IN WHOLE LIQUID EGG PRODUCTS BY ELECTRICAL AND THERMAL CONDUCTIVITY MEASUREMENTS

The total solids and fat contents of nine whole liquid egg products were assessed by means of electrical and thermal conductivity measurements. Linear correlations between conductivity values and total solids and fat contents were obtained with R2 values up to 0.995 and 0.990 and maximum errors of predic- 46 TABLE 6 - Linear regression models for the total solids (TS, %) and fat (FC, %) contents estimation from electrical (Ec, mS/cm) and thermal (Tc, W/mK) conductivity measurements.

The electrical conductivity of the albumen, yolk and egg mixtures linearly increased with temperature; at 20°C, temperature coefficients of 2.1%/°C, 2.1%/°C and 1.9 %/°C were respectively calculated. On the contrary, the thermal conductivity of the analysed products did not appear to be substantially influenced by the temperature of the liquid

Clinical, radiographic, and histologic evaluation of maxillary sinus lift procedure using a highly purified xenogenic graft (Laddec(®))

The aim of this study was to evaluate the clinical, radiographic and histologic results when a highly purified xenogenic bone (Laddec(®)) was used as grafting material in maxillary sinuses

Bone healing in extraction sockets covered with collagen membrane alone or associated with porcine-derived bone graft: a comparative histological and histomorphometric analysis

The present paper reports data of a randomized study aimed to analyse and compare the histologic and histomorphometric aspects of bone healing in extraction sites covered with collagen membrane alone or associated with porcine-derived bone graft

Trasformazioni dell’Apocalisse in Mario Vargas Llosa: dal fanatismo de La guerra del fin del mundo al cuore di tenebra de El sueño del celta

The paper aims to underline that in the Peruvian writer there is a double reading of the apocalypse. In the novel La guerra del fin del mundo the apocalypse is represented as a religious, political, environmental disruption of a world: the apocalypse is caused by ignorance and poverty, wich are the culture media of fanaticism, racism and religious dogmatism. In the last novel El sueño del celta, the apocalypse is instead caused by the lust for power and the abyss of evil present in the human being

Imágenes de la conquista: el encuentro de Cajamarca en Crónica de la Conquista del Perú y en Verdadera Relación de la Conquista del Perú

The news about Peru that reached Europe right after the conquest has always been an object of study and reflection. The first documents that describe Peru and its treasures were soon translated into Italian, shortly after their arrival to Spain; some of them were lost in their original form and remain available in Italian only. These documents played a major role in building the image of Peru along the sixteenth century. The paper is about the Cajamarca events described in those documents.Las primeras noticias de la conquista del Perú nunca han dejado de ser objeto de estudio y reflexión. Los primeros documentos que describen el Perú y sus riquezas fueron traducidos al italiano muy pronto, poco después de su llegada a España. Algunos de ellos se perdieron, por lo que ahora hay sólo traducciones italianas que los reproducen. El conjunto de estos escritos constituye una fuente muy particul ar de noticias que se difundieron en Europa y que jugaron un papel importante en la construcción de la imagen del Perú en el siglo XVI. Aquí se propone un estudio de dos fuentes de la conquista del Perú a partir de las noticias del acontecimiento de Cajamarca
