Streptococci and actinomyces that initiate colonization of the tooth surface frequently coaggregate with each other as well as with other oral bacteria. These observations have led to the hypothesis that interbacterial adhesion influences spatiotemporal development of plaque. To assess the role of such interactions in oral biofilm formation in vivo, antibodies directed against bacterial surface...
AIM To characterize the patterns of competition for a sample of drugs in the Portuguese pharmaceutical market before (January 2002-March 2003) and after (April 2003-June 2003) the introduction of the reference pricing system (RPS). METHODS We performed a descriptive, retrospective, longitudinal analysis, with monthly observations from January 2002 until June 2003 of 15 homogeneous groups. The...
The cyanobacterium Gloeothece sp. strain PCC 6909 and its sheathless mutant were tested for their abilities to remove copper ions from aqueous solutions, with the aim of defining the role of the various outermost polysaccharidic investments in the removal of the metal ions. Microscopy studies and chemical analyses revealed that, although the mutant does not possess a sheath, it releases large a...
AIMS Proper examination and accurate reporting of radical prostatectomy specimens (RPS) is essential in determining post-surgical treatment and predicting patient outcome. Surveys have demonstrated the absence of consensus on handling of RPS. The aim of this study was to determine whether significant information is lost when only half the horizontal tissue sections are examined. METHODS AND R...
In the cycle of photosynthetic reaction centers, the initially oxidized special pair of bacteriochlorophyll molecules is subsequently reduced by an electron transferred over a chain of four hemes of the complex. Here, we examine the kinetics of electron transfer between the proximal heme c-559 of the chain and the oxidized special pair in the reaction center from Rps. sulfoviridis in the range ...
tsimpli and dimitrakopoulou (2007) observed that uninterpretable features are unavailable in second language (l2) acquisition after the critical period. in this paper, we verify this claim by providing evidence from persian speaking learners of english as an l2 on the status of resumptive pronouns (rps) as uniterpretable features. unlike english which does not allow rps, persian shows various b...
Experiments were carried out to examine interaction between mechanical changes of the muscle-tendon unit and reduced reflex sensitivity after repeated and prolonged passive muscle stretching (RPS). There is some evidence that this interaction might be relevant also during active stretch-shortening cycle type of fatigue tasks. The results demonstrated a clear deterioration of voluntarily and ele...
A recurrent power series (RPS) method is constructed for the numerical integration of the equations of motion of a planet and its N satellites. The planet is considered as an oblate spheroid with the oblateness potential calculated up to the factor J4. The efficiency of the RPS method in terms of accuracy and speed is compared to that of the commonly used 10th-order Gauss-Jackson backward diffe...
The coaggregation receptor polysaccharides (RPS) of Streptococcus oralis and related species are recognized by lectin-like adhesins on other members of the oral biofilm community and by RPS-specific antibodies. The former interactions involve beta-GalNAc or beta-Gal containing host-like motifs in the oligosaccharide repeating units of these polysaccharides, whereas the latter involves features ...
Members of the ATP-binding cassette (ABC) superfamily of transporters have been implicated as major players in drug response. Single nucleotide polymorphisms (SNPs) in the ABC transporter genes may account for variation in drug response between individuals. Given the abundance of SNPs within the human genome, identification of functionally important SNPs is difficult. Here, we utilized signatur...
