1. La muerte como proceso: una perspectiva antropológica
This article combines recent approximations that question the homology between death and biological demise from an anthropological perspective with the tradition of studies that review the death rituals in the Andean geographical area. In particular, it examines how in El Cajón, Catamarca, Northeast Argentina the dead are incorporated in the cosmologic sche

2. Acanthobothrium Blanchard, 1848: diversidade filogenética das linhagens parasitas de arraias de água doce / Acanthobothrium Blanchard, 1848: phylogenetic diversity of the linages that parasitize freshwater stingrays
First we clarify some major points in the taxonomic history of Acanthobothrium. The authorship of the genus must be given to Blanchard in 1848, ocasion in which its first species, Acanthobothrium coronatum, was created. Therefore, the type species of Acanthobothrium is A. coronatum Blanchard, 1848, a junior synonym of A. corollatum (Abildgaard, 1790). Both A

3. Estudos físico-químicos e bioquímicos de uma proteína de 21 kDa do Trypanosoma cruzi / Physico-chemical and biochemical studies of a 21 kDa protein of Trypanosoma cruzi
A proteína P21 do Trypanosoma cruzi participa no processo de infecção da célula hospedeira, desse modo é de grande importância: elucidar as vias de sinalização induzidas pela proteína, bem como caracterizar a nível molecular e estrutural a P21. O que vai auxiliar no entendimento da função biológica da P21 e sua participação no processo de infe

4. PHYLOGENETICS AND MORPHOLOGICAL EVOLUTION OF SCLERACTINIAN CORALS
Scleractinian corals are modular organisms of great ecological and economic importance that may have solitary or colonial growth forms. In spite of the rich fossil record, the evolutionary history of the group is poorly understood and its taxonomy is highly artificial because many of the features commonly employed in systematic studies of the group exhibit l

5. Statistical method for rapid homology search.
A new method for homology search of DNA sequences is suggested. This method may be used to find extensive and not strong homologies with point mutations and deletions. The running program time for comparing sequences is less then the dynamic program algorithms at least at two orders of magnitude. It makes possible to use the method for homology searching thr

6. Association of Mouse Actin-binding Protein 1 (mAbp1/SH3P7), an Src Kinase Target, with Dynamic Regions of the Cortical Actin Cytoskeleton in Response to Rac1 Activation
Yeast Abp1p is a cortical actin cytoskeleton protein implicated in cytoskeletal regulation, endocytosis, and cAMP-signaling. We have identified a gene encoding a mouse homologue of Abp1p, and it is identical to SH3P7, a protein shown recently to be a target of Src tyrosine kinases. Yeast and mouse Abp1p display the same domain structure including an N-termin

7. Homologous genetic recombination as an intrinsic dynamic property of a DNA structure induced by RecA/Rad51-family proteins: A possible advantage of DNA over RNA as genomic material
Heteroduplex joints are general intermediates of homologous genetic recombination in DNA genomes. A heteroduplex joint is formed between a single-stranded region (or tail), derived from a cleaved parental double-stranded DNA, and homologous regions in another parental double-stranded DNA, in a reaction mediated by the RecA/Rad51-family of proteins. In this r

8. Nir2, a Novel Regulator of Cell Morphogenesis
Cell morphogenesis requires dynamic reorganization of the actin cytoskeleton, a process that is tightly regulated by the Rho family of small GTPases. These GTPases act as molecular switches by shuttling between their inactive GDP-bound and active GTP-bound forms. Here we show that Nir2, a novel protein related to Drosophila retinal degeneration B (RdgB), mar

9. Dynamic Localization and Function of Bni1p at the Sites of Directed Growth in Saccharomyces cerevisiae
Formin homology (FH) proteins are implicated in cell polarization and cytokinesis through actin organization. There are two FH proteins in the yeast Saccharomyces cerevisiae, Bni1p and Bnr1p. Bni1p physically interacts with Rho family small G proteins (Rho1p and Cdc42p), actin, two actin-binding proteins (profilin and Bud6p), and a polarity protein (Spa2p).

10. MIPS: a database for protein sequences, homology data and yeast genome information.
The MIPS group (Martinsried Institute for Protein Sequences) at the Max-Planck-Institute for Biochemistry, Martinsried near Munich, Germany, collects, processes and distributes protein sequence data within the framework of the tripartite association of the PIR-International Protein Sequence Database (,). MIPS contributes nearly 50% of the data input to the P

11. Characterization of a dynamic S layer on Bacillus thuringiensis.
The surfaces of three Bacillus thuringiensis strains possess an S layer composed of linear arrays of small particles arranged with p2 symmetry and with a = 8.5 nm, b = 7.2 nm, and gamma = 73 degrees. Platinum shadows of whole cells and S-layer fragments revealed the outer surface of the array to be smooth and the inner surface to be corrugated. Treatment wit

12. The paired Ig-like receptor PIR-B is an inhibitory receptor that recruits the protein-tyrosine phosphatase SHP-1
An emerging family of cell surface inhibitory receptors is characterized by the presence of intracytoplasmic immunoreceptor tyrosine-based inhibition motifs (ITIM). These ITIM-bearing inhibitory receptors, which are typically paired with activating isoforms, associate with Src homology domain 2-containing phosphatases following ITIM tyrosine phosphorylation.
