Bacteria of the phylum Planctomycetes are of special interest for the study of compartmental cellular organization. Members of this phylum share a very unusual prokaryotic cell plan, featuring several membrane-bound compartments. Recently, it was shown that this cellular organization might extend to certain members of the phylum Verrucomicrobia. The Planctomycete cell plan has been defined as f...

Because a definite diagnosis of prion diseases relies on the detection of the abnormal isoform of prion protein (PrPSc), it has been urgently necessary to establish a non-invasive diagnostic test to detect PrPSc in human prion diseases. To evaluate diagnostic usefulness and reliability of the detection of protease-resistant prion protein in urine, we extensively analyzed proteinase K (PK)-resis...

Leptospira is the etiologic agent of leptospirosis, a bacterial zoonosis distributed worldwide. Leptospiral lipopolysaccharide is a protective immunogen, but the extensive serological diversity of leptospires has inspired a search for conserved outer membrane proteins (OMPs) that may stimulate heterologous immunity. Previously, a global analysis of leptospiral OMPs (P. A. Cullen, S. J. Cordwell...

[email protected] spheres with a structure were synthesized and thermally annealed at 800 ºC to obtain (SiO2@CSs). The silica core was removed by etching NaOH, hollow carbon (CSs) being obtained. particle size of SiO2@CSs CSs increased the ethanol/water (E/W) volumetric ratio (2, 4.5, 7) employed in first synthesis step (i.e., Stöber's method particles). Moreover, average diameter materials pre...

Abstract Water bodies are being contaminated daily due to industrial, agricultural and domestic effluents. In the last decades, harmful organic micropollutants (OMPs) have been detected in surface groundwater at low concentrations discharge of untreated effluent natural water bodies. As a consequence, aquatic life public health endangered. Unfortunately, traditional treatment methods ineffectiv...

Francisella tularensis is a gram-negative coccobacillus that is capable of causing severe, fatal disease in a number of mammalian species, including humans. Little is known about the proteins that are surface exposed on the outer membrane (OM) of F. tularensis, yet identification of such proteins is potentially fundamental to understanding the initial infection process, intracellular survival, ...

A comprehensive meningococcal vaccine is yet to be developed. In the absence of a vaccine that immunizes against the serogroup B capsular polysaccharide, this can only be achieved by targeting subcapsular antigens, and a number of outer-membrane proteins (OMPs) are under consideration as candidates. A major obstacle to the development of such a vaccine is the antigenic diversity of these OMPs, ...

Recent research has shown the developments made in the analysis of gross movement patterns in tennis, but such research has yet to be extended to the field of beach volleyball. This study was designed to develop a method for analysing gross movement patterns so as to quantify movement types and their relationship to real competition and performed during the European Beach Volleyball Championshi...

The outer membrane proteins (OMPs) of Branhamella catarrhalis were studied in an effort to identify surface-exposed determinants that are conserved among strains of the bacterium. Aliquots of polyclonal antiserum were absorbed individually by strains of B. catarrhalis. The absorbed antisera were tested in comparison with unabsorbed antiserum in an immunoblot assay against OMPs of the homologous...

A serotyping system for nontypable Haemophilus influenzae (NTHI) was developed by using isolated outer membrane protein (OMP) preparations and rabbit antisera. OMPs of 23 strains were isolated by molecular sieve chromatography of outer membranes in 1.5% sodium deoxycholate buffer. These OMP preparations were relatively free of lipopolysaccharide as determined by silver staining of sodium dodecy...
