neisseria meningitidis is a major causative agent of bacterial septicemia and meningitis in humans. currently, there are no vaccines to prevent disease caused by strains of n.meningitidis serogroup b. the class 1 outer membrane protein (omp) has been named pora which is a cation selective transmembrane protein of 45 kda that forms trimeric pore in the meningococcal outer membrane. pora from ser...

a single column cation exchanger resin was used to eliminate cations from renet cheese whey, with particular reference to the improvement of taste and flavor. ten panelists were convened to assess the contribution of the mineral components to the salty taste of whey, judging on the basis of taste, flavor and color. the organoleptic characteristics of untreated whey were arbitrarily assigned...

In the title hydrated molecular salt, C22H25N2 (+)·C6H4FO3S(-)·H2O, the cation displays whole mol-ecule disorder over two sets of sites in a 0.780 (5):0.220 (5) ratio. The quinolinium ring system is essentially planar, with r.m.s. deviations of 0.0162 and 0.0381 Å for the major and minor disorder components, respectively. The dihedral angles between the mean plane of the quinolinium ring system...

Chamaecyparis formosensis is a precious conifer endemic in Taiwan. To understand the sesquiterpene synthesis mechanism in this tree, full-length cDNA of a putative sesquiterpene synthase (sesqui-TPS), designated Cf-Cad , was obtained by rapid amplifi cation of complementary DNA ends-polymerase chain reaction. Cf-Cad is 1812 bp in length. To identify its function, recombinant protein from Escher...

The asymmetric unit of the title compound, 2C(5)H(7)N(2) (+)·SO(4) (2-)·H(2)O, contains two 4-amino-pyridinium cations (A and B), a sulfate dianion and a water mol-ecule. One of the 4-amino-pyridinium cations (B) is disordered over two orientations with refined site occupancies of 0.568 (4) and 0.432 (4). The non-H atoms of the 4-amino-pyridinium cations are essentially coplanar, with a maximum...

A simple synthesis of the zerovalent complex Mo[P(OCH(3))(3)](6) has been devised from a potassium reduction of MoCl(4)(tetrahydrofuran)(2) followed by reaction with trimethyl phosphite at 70 degrees . Protonation of this octahedral complex gave only low yields of the expected seven-coordinate hydride, HMo[P(OCH(3))(3)](6) (+). The major product was an octahedral nonhydridic cation, Mo[P(OCH(3)...

The use of a recently developed cation-exchange HPLC packing material for the separation of hemoglobin types in human blood has been investigated. Adult and newborn hemolysates from normal individuals and from subjects with hemoglobin disorders were analyzed using a weak cation carboxymethyl-bonded phase on 5-micron-particle-size silica. Elution was accomplished using a Bistris (2-[bis(2-hydrox...

The title compound, [Fe(C(12)H(8)N(2))(3)](C(6)H(5)N(2)O(2))(2), consists of one [Fe(phen)(3)](2+) cation (phen = 1,10-phenanthroline) and two 1,1-dicyano-2-eth-oxy-2-oxoethanide anions. Five atoms of the anion are disordered over two positions [site occupancy = 0.521 (13) for the major component]. In the complex cation, the Fe(II) atom is coordinated by six N atoms from three phen ligands in a...

Veri cation for Hand Sign Recognition Yuntao Cui and John J. Weng Department of Computer Science Michigan State University East Lansing, MI 48824, USA E-mail: fcui,[email protected] Abstract This paper presents a prediction-and-veri cation segmentation scheme using attention images from multiple xations. A major advantage of this scheme is that it can handle a large number of di erent deformabl...
