Resumen
ABSTRACT Immunization of mice with pneumococcal surface adhesin A (PsaA) emulsified in complete Freund's adjuvant (CFA) provides protection against systemic infection with Streptococcus pneumoniae. Because the use of CFA is not acceptable in humans, we sought to develop alternative means of enhancing the immunogenicity of protein antigens of potential use in pneumococcal vaccines. We designed a series of genetic constructs in which coding sequences for PsaA were linked to sequences encoding either murine interleukin-2 (mIL-2), mIL-4, or two copies of an immunostimulatory nonapeptide derived fr

Anatomical variation of the course of posterior superior alveolar artery (PSAA) within maxillary bone are vital information for surgeons before any maxillary surgery. This study was designed to evaluate the variations of PSAA by determining the prevalence of intraosseous PSAA and assessing the anatomical reference points and diameter of the PSAA. Comparison between dentate and edentulous alveolus was also done. One hundred CBCT images were included in this study to enumerate the prevalence of intraosseous PSAA in maxilla.

ABSTRACT psaA encodes a 37-kDa pneumococcal lipoprotein which is part of an ABC Mn(II) transport complex. Streptococcus pneumoniae D39 psaA mutants have previously been shown to be significantly less virulent than wild-type D39, but the mechanism underlying the attenuation has not been resolved. In this study, we have shown that psaA and psaD mutants are highly sensitive to oxidative stress, i.e., to superoxide and hydrogen peroxide, which might explain why they are less virulent than the wild-type strain.

Resumen
The Posterior Superior Alveolar Artery (PSAA) provides vascular support to molars, gingiva, and maxillary sinus. A tear of the PSAA may cause profuse hemorrhages which may lead to complications at a surgical level. As such, it becomes crucial to anatomically analyse several features regarding the PSAA as well as the area surrounding it. In this paper, we are particularly interested in the study of the complexity of the periodontal tissue structure which appears close to the location of the PSAA.

ABSTRACT PsaA of Streptococcus pneumoniae, originally believed to be an adhesin, is the lipoprotein component of an Mn2+ transporter. Mutations in psaA cause deficiencies in growth, virulence, adherence, and the oxidative stress response. Immunofluorescence microscopy shows that PsaA is hidden beneath the cell wall and the polysaccharide capsule and only exposed to antibodies upon cell wall removal. A psaBC deletion mutant, expressing PsaA normally, was as deficient in adherence to Detroit 562 cells as were strains lacking PsaA. Thus, PsaA does not appear to act directly as an adhesin, but rat

ABSTRACT Larger numbers of pneumococci were detected in the nasal tract compared to the lung, cervical lymph nodes, and spleen 1, 2, 4, 7, 14, and 21 days after nasal challenge with Streptococcus pneumoniae strain EF3030. In this mouse model of pneumococcal carriage, peripheral S. pneumoniae pneumococcal surface adhesin A (PsaA)-specific humoral responses (immunoglobulin G2a [IgG2a] ≫ IgG1 = IgG2b &gt; IgG3) were significantly higher than pneumococcal surface protein A (PspA)-specific, genetic toxoid derivative of pneumolysin (PdB)-specific, or pneumococcal surface protein C (PspC)-specific se

Resumen
Salinity is considered to be one of the most severe problems in worldwide agricultural production, but the published investigations give contradictory results of the effect of ionic and osmotic stresses on photosynthesis. In the present study, long-term effects of both ionic and osmotic stresses, especially on photosynthesis, were investigated using the moderately halotolerant cyanobacterium Synechocystis sp. PCC 6803. Our results show that the PSII activity and the photosynthetic capacity tolerated NaCl but a high concentration of sorbitol completely inhibited both activities. In line with th

Abstract Streptococcus pneumoniae (S. pneumoniae) is a leading agent worldwide, which could cause community-acquired pneumonia, bacteraemia, and meningitis. However, the pathogeneses remain unclear. This study was conducted to investigate gene pneumococcal surface antigen A (psaA) expression and the adhesion differences of various S. pneumoniae strains. A total of 24 (N) S. pneumoniae strains were collected: 11 from blood (bd-SP), 12 from sputum (sd-SP) and one was ATCC49619. One millilitre of A549 pneumocytes (3.3×108/L) and 100 µl of each S. pneumoniae strain at 1.0 McFarland were mixed and

A significant effect of soil drought on the gene expression (psaA, psaB, lhca2, psbA, lhcb1 and lhcb4) encoding key structural proteins of reaction centers (RC) and light harvesting complexes (LHC) of photosystems (PS) in barley leaves was shown. A change in the level of gene expression observed under drought conditions is light-dependent — in normal light, there is a significant increase in the expression of lhcb1 (1.6 times), psaA (1.8 times) and psaB (2.5 times) genes, encoding PS I and II proteins, and in the dim light, on the contrary, there is a decrease in the expression of genes encodi

ABSTRACT Antibodies to capsular polysaccharide (PS) are protective against systemic infection by Streptococcus pneumoniae, but the large number of pneumococcal serogroups and the age-related immunogenicity of pure PS limit the utility of PS-based vaccines. In contrast, cell wall-associated proteins from different capsular serotypes can be cross-reactive and immunogenic in all age groups. Therefore, we evaluated three pneumococcal proteins with respect to relative accessibility to antibody, in the context of intact pneumococci, and their ability to elicit protection against systemic infection b

ABSTRACT The importance of Mn2+ for pneumococcal physiology and virulence has been studied extensively. However, the specific cellular role(s) for which Mn2+ is required are yet to be fully elucidated. Here, we analyzed the effect of Mn2+ limitation on the transcriptome and proteome of Streptococcus pneumoniae D39. This was carried out by comparing a deletion mutant lacking the solute binding protein of the high-affinity Mn2+ transporter, pneumococcal surface antigen A (PsaA), with its isogenic wild-type counterpart.
