Im Rahmen der vorliegenden Studie sollte der Einfluss des Weichteilschadens auf das klinische Ergebnis nach offener Ellenbogenluxation untersucht werden.. Von Oktober 2008 bis August 2015 wurden insgesamt 230 Patienten mit Ellenbogenluxation behandelt. Diese retrospektive Studie umfasst 21 Fälle von offenen Ellenbogenluxationen. Das Durchschnittsalter der Patienten betrug 49 Jahre alt (20–83 Jahre), 6 Patienten waren weiblich (29%), 15 männlich (71%). Das Bewegungsausmaß des verletzten und unverletzten Ellenbogens wurde erhoben und das funktionelle Ergebnis u. a. mittels Mayo Elbow Performance Score (MEPS), Mayo Wrist Score (MWS) und dem Disability of Arm, Shoulder and Hand (DASH) Score erfasst. Zusätzlich wurden Komplikationen und Revisionsoperationen aufgezeichnet. Der Einfluss des Weichteilschadens (I°/II° offen vs. III° offen) und des Luxationstyps (einfach vs. komplex) auf das klinische Ergebnis wurde analysiert.. Offene Ellenbogenluxationen können mit einem zufriedenstellenden klinischen Ergebnis einhergehen. Insbesondere komplexe offene Ellenbogenluxationen sind jedoch sehr komplikationsbehaftet, wobei neurovaskuläre Komplikationen am häufigsten auftreten.. The current high rate of multidrug-resistant gram-negative bacteria infections among hospitalised patients with cUTIs in the studied area is alarming. Our predictive model could be useful to avoid inappropriate antibiotic treatment and implement antibiotic stewardship policies that enhance the use of carbapenem-sparing regimens in patients at low risk of multidrug-resistance.. The results indicated differential patterns of Inhibition of Return between the High and Low shape/weight based self-worth groups. The High group displayed increased inhibition of return for the shape/weight stimuli relative to control stimuli, while the Low group displayed reduced inhibition of return for the shape/weight stimuli compared to control stimuli. The ED group displayed a similar pattern of results to the High group, but this did not reach significance.. The current findings indicate that young women without an eating disorder who base their self-worth on shape/weight display a pattern of avoidance of shape/weight stimuli that is in direct contrast to those at low risk of developing eating disorders. The possible implications of these specific patterns of inhibition of return across those at varying levels of risk for an eating disorder are discussed along with their implications for intervention approaches.. These results indicated that Sr. An unusually high HbA

A Gram-stain-negative, aerobic, rod-shaped bacterium motile by means of a single polar flagella, strain ST-6T, was isolated from a brown alga (Sargassum thunbergii) collected in Jeju, Republic of Korea. Strain ST-6T was psychrotolerant, growing at 4-30 °C (optimum 20 °C). Phylogenetic analysis based on 16S rRNA and gyrB gene sequences revealed that strain ST-6T belonged to a distinct lineage in the genus Shewanella. Strain ST-6T was related most closely to Shewanella basaltis J83T, S. gaetbuli TF-27T, S. arctica IT12T, S. vesiculosa M7T and S. aestuarii SC18T, showing 96-97 % and 85-70 % 16S rRNA and gyrB gene sequences similarities, respectively. DNA-DNA relatedness values between strain ST-6T and the type strains of two species of the genus Shewanella were <22.6 %. The major cellular fatty acids (>5 %) were summed feature 3 (comprising C16:1ω7c and/ or iso-C15:0 2-OH), C16:0, iso-C13:0 and C17:1ω8c. The DNA G+C content of strain ST-6Twas 42.4 mol%, and the predominant isoprenoid quinones were menaquinone MK-7 and ubiquinones Q-7 and Q-8. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain ST-6T is considered to represent a novel species of the genus Shewanella, for which the name Shewanella algicola sp. nov. is proposed. The type strain is ST-6T (= KCTC 23253T = JCM 31091T).

A novel Gram-stain-negative, straight or slightly curved rod-shaped, non-spore-forming, facultatively anaerobic bacterium with a single polar flagellum, designated RZB5-4T, was isolated from a sample of the red algae Gelidium amansii collected from the coastal region of Rizhao, PR China (119.625° E 35.517° N). The organism grew optimally between 24 and 28 °C, at pH 7.0 and in the presence of 2-3 % (w/v) NaCl. The strain required seawater or artificial seawater for growth, and NaCl alone did not support growth. Strain RZB5-4T contained C16 : 1ω7c and/or C16 : 1ω6c, C16 : 0 and iso-C15 : 0 as the dominant fatty acids. The respiratory quinones detected in strain RZB5-4T were ubiquinone 7, ubiquinone 8, menaquinone 7 and methylmenaquinone 7. The polar lipids of strain RZB5-4T comprised phosphatidylethanolamine, phosphatidylglycerol, phosphatidylmonomethylethanolamine, one unidentified glycolipid, one unidentified phospholipid and one unknown lipid. The DNA G+C content of strain RZB5-4T was 47 mol %. Phylogenetic analysis based on 16S rRNA and gyrase B (gyrB) gene sequences showed that strain RZB5-4T belonged to the genus Shewanella, clustering with Shewanella waksmanii ATCC BAA-643T. Strain RZB5-4T exhibited the highest 16S rRNA gene sequence similarity value (96.6 %) and the highest gyrB gene sequence similarity value (80.7 %), respectively, to S. waksmanii ATCC BAA-643T. On the basis of polyphasic analyses, strain RZB5-4T represents a novel species of the genus Shewanella, for which the name Shewanella gelidii sp. nov. is proposed. The type strain is RZB5-4T (=JCM 30804T=KCTC 42663T=MCCC 1K00697T).

A Gram-stain-negative bacterium, designated strain CBA4601(T), was isolated from a seawater sample obtained off the coast of Jeju Island, Korea. The organism grew in the presence of 0-4% (w/v) NaCl and at 20-35 °C and pH 7.0-9.0, with optimal growth in 2% NaCl, and at 25 °C and pH 8.0. Phylogenetic trees based on 16S rRNA gene sequences showed that strain CBA4601(T) was related to the genus Ferrimonas within the class Gammaproteobacteria. 16S rRNA gene sequence similarity between strain CBA4601(T) and Ferrimonas marina A4D-4(T), the most closely related species, was 96.9%. The G+C content of the genomic DNA from strain CBA4601(T) was 54.2 mol%, and the isoprenoid quinones menaquinone 7 (MK-7), ubiquinone 7 (Q-7) and ubiquinone 8 (Q-8) were detected. The major fatty acids were C(17:1)ω8c, C(18:1)ω9c and C(16:0), and the major polar lipids were phosphatidylethanolamine, phosphatidylglycerol and an unidentified ninhydrin-positive phospholipid. On the basis of this taxonomic study using a polyphasic approach, strain CBA4601(T) represents a novel species of the genus Ferrimonas, for which the name Ferrimonas pelagia sp. nov. is proposed. The type strain is CBA4601(T) ( =KACC 16695(T) =KCTC 32029(T) =JCM 18401(T)).

A novel beige-pigmented, Gram-staining-negative, coccoid, motile and facultatively anaerobic bacteria, designated strain CJ24(T), was isolated from the tidal flat sediment of the Yellow Sea in South Korea. Characterization of this strain was performed on the basis of polyphasic taxonomic methods. Phylogenetic analysis of the 16S rRNA and gyrB genes revealed that strain CJ24(T) belongs to the genus Ferrimonas, sharing the highest 16S rRNA gene sequence similarity of 96.9 % with Ferrimonas marina DSM 16917(T). Strain CJ24(T) was able to grow optimally at 30 °C, at pH 6.0 and in the presence of 2 % NaCl (w/v). As an isoprenoid quinone, menaquinone (MK-7) was predominantly identified from this strain, while ubiquinone (Q-7) was also present as a minor component. The DNA G+C content of strain CJ24(T) was 60.2 mol%. The most abundant cellular fatty acids were C15 : 0 iso, C18 : 1ω9c, C16 : 0 and C17 : 0 iso. Therefore, strain CJ24(T) represents a novel species in the genus Ferrimonas for which the name Ferrimonas gelatinilytica sp. nov. is proposed; the type strain is CJ24(T) ( = KACC 17065(T) = JCM 18720(T)).

Cytochrome aa(3)-600 is one of the principle respiratory oxidases from Bacillus subtilis and is a member of the heme-copper superfamily of oxygen reductases. This enzyme catalyzes the two-electron oxidation of menaquinol and the four-electron reduction of O(2) to 2H(2)O. Cytochrome aa(3)-600 is of interest because it is a very close homologue of the cytochrome bo(3) ubiquinol oxidase from Escherichia coli, except that it uses menaquinol instead of ubiquinol as a substrate. One question of interest is how the proteins differ in response to the differences in structure and electrochemical properties between ubiquinol and menaquinol. Cytochrome bo(3) has a high affinity binding site for ubiquinol that stabilizes a ubi-semiquinone. This has permitted the use of pulsed EPR techniques to investigate the protein interaction with the ubiquinone. The current work initiates studies to characterize the equivalent site in cytochrome aa(3)-600. Cytochrome aa(3)-600 has been cloned and expressed in a His-tagged form in B. subtilis. After isolation of the enzyme in dodecylmaltoside, it is shown that the pure enzyme contains 1 eq of menaquinone-7 and that the enzyme stabilizes a mena-semiquinone. Pulsed EPR studies have shown that there are both similarities as well as significant differences in the interactions of the mena-semiquinone with cytochrome aa(3)-600 in comparison with the ubi-semiquinone in cytochrome bo(3). Our data indicate weaker hydrogen bonds of the menaquinone in cytochrome aa(3)-600 in comparison with ubiquinone in cytochrome bo(3). In addition, the electronic structure of the semiquinone cyt aa(3)-600 is more shifted toward the anionic form from the neutral state in cyt bo(3).

A novel marine bacterial strain, PV-4(T), isolated from a microbial mat located at a hydrothermal vent of Loihi Seamount in the Pacific Ocean, has been characterized. This micro-organism is orangey in colour, Gram-negative, polarly flagellated, facultatively anaerobic and psychrotolerant (temperature range, 0-42 degrees C). No growth was observed with nitrate, nitrite, DMSO or thiosulfate as the electron acceptor and lactate as the electron donor. The major fatty acid detected in strain PV-4(T) was iso-C(15 : 0). Strain PV-4(T) had ubiquinones consisting mainly of Q-7 and Q-8, and possessed menaquinone MK-7. The DNA G+C content of the strain was 53.8 mol% and the genome size was about 4.5 Mbp. Phylogenetic analyses based on 16S rRNA gene sequences placed PV-4(T) within the genus Shewanella. PV-4(T) exhibited 16S rRNA gene sequence similarity levels of 99.6 and 97.5 %, respectively, with respect to the type strains of Shewanella aquimarina and Shewanella marisflavi. DNA from strain PV-4(T) showed low mean levels of relatedness to the DNAs of S. aquimarina (50.5 %) and S. marisflavi (8.5 %). On the basis of phylogenetic and phenotypic characteristics, the bacterium was classified in the genus Shewanella within a distinct novel species, for which the name Shewanella loihica sp. nov. is proposed. The type strain is PV-4(T) (=ATCC BAA-1088(T)=DSM 17748(T)).

A quinol-oxidase activity was detected in crude extracts of the thermoacidophilic archaebacterium Thermoplasma acidophilum. The activity was optimal at pH 5.4 and 50 degrees C. The Km for ubiquinol-10 was 18 microM. The enzyme was inhibited by 2n-heptyl-4-hydroxyquinoline N-oxide with a Ki of 150 nM. Ubiquinols with different side-chain lengths were oxidized at similar rates, whereas menaquinols were converted at 6-12-fold higher rates compared to ubiquinols. Membranes from T. acidophilum contain cytochromes of b, d and a1 types, as shown by optical spectroscopy. CO difference spectroscopy suggests the existence of a cytochrome o. A b-type cytochrome with an apparent molecular mass of 18 kDa was purified in the presence of high detergent concentrations. It readily forms dimers on SDS/PAGE. This cytochrome also contains Cu, as shown by atomic-absorption spectroscopy. Redox titration suggests that the 18-kDa cytochrome may contain 2 heme groups; b558 with a midpoint potential of 75 mV and b562/553 with a midpoint potential of -150 mV.
