Effect of pH on technological parameters and physicochemical and texture characteristics of the pasta filata cheese Telita.

The objective of this study was to determine the effect of stretching pH on technological parameters and physicochemical and texture characteristics of the pasta filata cheese Telita. A no-brine cheese-making method was used to control both melting and stretching temperatures. Six vats of cheese, each with a different stretching pH (5.

Psychiatry in Venezuela.

The Bolivarian Republic of Venezuela covers 916 445 km; to the north is the Caribbean Sea, to the south-east the Amazonian region and the plains of Brazil and Colombia, and to the west the Andes and the Colombian Guajira peninsula. Its estimated population (2004) is 25 226 million, which is concentrated along the north coastal area, where the population density exceeds 200 inhabitants per km; most of the territory remains almost inhabited (fewer than 6 inhabitants per km), in particular the border areas. The population is mainly urban: 70% live in cities with more than 50 000 inhabitants.

Ultrastructure of hepatic metastases from a colon leiomyosarcoma.

The electron microscopic examination of biopsies from liver metastases of a colon leiomyosarcoma showed the existence of alterations not previously reported in primary tumors of that kind. Those abnormalities included proliferation of lysosomal structures as multivesicular bodies, myelin-like figures, lipofuscin granules and autophagic vacuoles, along with mitochondrial changes as concentric and vesiculated cristae, and presence of dense granules and elongated inclusions. This study suggests that, in this tumor and host tissue, the so-called invasive phenotype, which is supposed to form the metastases, could have a distinct morphological picture at the ultrastructural level.
