1. Efeito das condições de preparação sobre as propriedades do óxido de zircônio sulfatado contendo ferro.
Sulfated oxide-based catalysts have found several industrial applications mainly in reactions which demand for strong acid sites. In order to develop methods to get acidic oxides, the effect of the preparation methods on the properties of iron-doped zirconia oxides was studied in this work.The precursors were prepared by process sol-gel from iron nitrate and

2. Decorin is one of the proteoglycans expressed in Walker 256 rat mammary carcinoma
Proteoglycan and glycosaminoglycan content was analyzed in a model of rat mammary carcinoma to study the roles of these compounds in tumorigenesis. Hyaluronic acid and proteoglycans bearing chondroitin and/or dermatan sulfate chains were detected in solid tumors obtained after subcutaneous inoculation of Walker 256 rat carcinoma cells. About 10% of sulfated

3. Estudo do efeito dos parametros fisicos e quimicos de adsorvente solido no processo de adsorção de SO2 em calcario
The process of energy generation, in special, the fluidized bed combustion, is responsible for gas emission to the atmosphere, generating serious enviroment problems. With the aim to minimize this emission, it has been used the solid alkaline injection, usually the limestone, during the fossil fuel bum. The efficiency of the S02 removal process, through the

4. Analysis of pregnenolone and dehydroepiandrosterone in rodent brain: cholesterol autoxidation is the key
Pregnenolone (PREG) and dehydroepiandrosterone (DHEA), and their respective sulfated forms PREGS and DHEAS, were among the first steroids to be identified in rodent brain. However, unreliable steroid isolation and solvolysis procedures resulted in errors, particularly in the case of brain steroid sulfates analyzed by radioimmunology or GC-MS of liberated fre

5. The role of bacterial cell wall hydrophobicity in adhesion.
In this study, the adhesion of bacteria differing in surface hydrophobicity was investigated. Cell wall hydrophobicity was measured as the contact angle of water on a bacterial layer collected on a microfilter. The contact angles ranged from 15 to 70 degrees. This method was compared with procedures based upon adhesion to hexadecane and with the partition of

6. The Tyrosine Sulfate-rich Domains of the LRR Proteins Fibromodulin and Osteoadherin Bind Motifs of Basic Clusters in a Variety of Heparin-binding Proteins, Including Bioactive Factors*
The small leucine-rich repeat proteins, fibromodulin and osteoadherin, have N-terminal extensions with a variable number of O-sulfated tyrosine residues. This modification combined with a number of aspartic and glutamic acid residues results in a highly negatively charged domain of less than 30 amino acids. We hypothesized that this domain shares functional

7. Identification of a Neospora caninum Microneme Protein (NcMIC1) Which Interacts with Sulfated Host Cell Surface Glycosaminoglycans
The invasive stages of apicomplexan parasites enter their host cells through mechanisms which are largely conserved throughout the phylum. Host cell invasion is divided into two distinct events, namely, adhesion onto the host cell surface and the actual host cell entry process. The former is mediated largely through microneme proteins which are secreted at t
