Citricoccus parietis sp. nov., isolated from a mould-colonized wall and emended description of Citricoccus alkalitolerans Li et al. 2005

A Gram-positive, coccoid-shaped organism (strain 02-Je-010T), forming yellow-pigmented colonies was isolated from the wall of an indoor environment. On the basis of 16S rRNA gene sequence similarity studies, it was shown that strain 02-Je-010T belongs to the genus Citricoccus with sequence similarities of 98.9?% to Citricoccus alkalitolerans DSM 15665T and 98.6?% to Citricoccus muralis DSM 14442T. Cell-wall sugars were mannose and glucose. The diagnostic diamino acid of the peptidoglycan was lysine. The major menaquinones detected were MK-9(H2) and MK-8(H2). The polar lipid profile consisted of the major lipids diphosphatidylglycerol, phosphatidylglycerol and phosphatidylinositol and moderate amounts of two unknown phospholipids and two unknown glycolipids. The fatty acid profile comprised major amounts of anteiso-C15?:?0, anteiso-C17?:?0 and iso-C15?:?0. All these data supported the affiliation of strain 02-Je-010T to the genus Citricoccus. The results of DNA–DNA hybridization and physiological and biochemical tests allowed genotypic and phenotypic differentiation of strain 02-Je-010T from the two recognized Citricoccus species. For these reasons, strain 02-Je-010T represents a novel species, for which the name Citricoccus parietis sp. nov. is proposed, with the type strain 02-Je-010T (=CCUG 57388T=CCM 7609T)

Top down or bottom up? A cross-national study of vertical occupational sex segregation in twelve European Countries

Starting with a comparative assessment of different welfare regimes and political economies from the perspective of gender awareness and pro-women policies, this paper identifies the determinants of cross-national variation in women's chances of being in a high-status occupation in twelve West European countries. Special emphasis is given to size and structure of the service sector, including share of women in public employment and structural factors such as trade union density and employment protection. The first level of comparison between men and women concentrates on gender representation in the higher echelons of the job hierarchy, while in the second section we extend the scope of analysis, comparing women in high-status occupations and low-wage employment in order to allow for a more nuanced study of gender and class interaction. The first analysis is based on European Social Survey data for the years 2002, 2004, 2006, and 2008, capturing recent trends in occupational dynamics. Results indicate that in general a large service sector and a high trade union density enhance women's chances of being in a high-status occupations while more specifically a large public sector helps to reduce channeling women in low-wage employment. Thus, equality at the top can well be paired with inequality at the bottom, as postindustrial countries with a highly polarized occupational hierarchy such as the UK show. --occupational sex segregation,gender equality,public sector employment,cross-national comparison

Microlunatus parietis sp. nov., isolated from an indoor wall

A Gram-positive, coccoid, non-endospore-forming actinobacterium (strain 12-Be-011T) was isolated from indoor wall material. Based on 16S rRNA gene sequence comparisons, strain 12-Be-011T was clearly shown to belong to the genus Microlunatus and was most closely related to Microlunatus panaciterrae Gsoil 954T (95.7 %), Microlunatus soli CC-12602T (94.9 %), Microlunatus ginsengisoli Gsoil 633T (94.8 %), Microlunatus aurantiacus YIM 45721T (95.5 %) and Microlunatus phosphovorus DSM 10555T (94.7 %). The cell-wall peptidoglycan contained ll-diaminopimelic acid as the diagnostic diamino acid. Mycolic acids were absent. The major menaquinone was MK-9(H4). The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, two unknown phospholipids and one unknown glycolipid. The major fatty acids of iso-C15:0, anteiso-C15:0 and iso-C16:0 supported the affiliation of strain 12-Be-011T to the genus Microlunatus. Physiological and biochemical test results allowed a clear phenotypic differentiation of strain 12-Be-011T from all other species of the genus Microlunatus. Hence, strain 12-Be-011T can be regarded as a representative of a novel species, for which the name Microlunatus parietis sp. nov. is proposed, with the type strain 12-Be-011T (=DSM 22083T=CCM 7636T)

Kytococcus aerolatus sp. nov., isolated from indoor air in a room colonized with moulds

A Gram-positive, coccoid bacterial isolate (02-St-019/1(T)), forming beige pigmented colonies was obtained from an indoor air sample. Based on 16S rRNA gene sequence similarity studies it was determined that this isolate 02-St-019/1(T) belonged to the genus Kytococcus, showing sequence similarties of 98.6% to Kytococcus schroeteri DSM 13884(T) and 98.3% to Kytococcus sedentarius DSM 20547(T), respectively. The diagnostic diaminoacid of the peptidoglycan was lysine, cell wall sugars were ribose and xylose. The major menaquinones detected were MK-7 and MK-8. The polar lipid profile consisted of the major phospholipids diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylserine and phosphatidylinositol mannoside. Fatty acid patterns were composed of major amounts of the iso- and anteiso-branched fatty acids anteiso C(17:0), iso C(15:0) and iso C(17:0) and unsaturated fatty acids (C(17:1) omega8c, iso C(17:1) omega9c, and C(17:1) omega8c) with smaller amounts of the straight-chain fatty acids C(15:0), C(16:0) and C(17:0). The results of DNA-DNA hybridizations and physiological and biochemical tests clearly allowed a genotypic and phenotypic differentiation of strain 02-St-019/1(T) from the two described Kytococcus species. On the basis of these results a novel species to be named Kytococcus aerolatus sp. nov., is proposed, with the type strain 02-St-019/1(T) (=DSM 22179(T)=CCM 7639(T))

Aufrechterhaltung des Sporttreibens - Eine längsschnittliche Online-Befragung bei Erwerbstätigen

Die Arbeit behandelt die Aufrechterhaltung des Sporttreibens unter Berücksichtigung der Regelmäßigkeit. Anders als in bisherigen Studien werden Erkenntnisse über die Aufrechterhaltung nicht durch Vergleich mit dem Abbruch, sondern durch Vergleich von regelmäßigem und unregelmäßigem Sporttreiben gewonnen. Erstmals werden diese beiden \u27Sporttypen\u27 deskriptiv dargestellt. Im Längsschnitt ergeben sich mit Hilfe des MoVo-Modells Hinweise auf Ursachen der regelmäßigen Sportaktivität

Investigating the effect of a nap following experimental trauma on analogue PTSD symptoms

Cognitive models assume that the incomplete integration of a traumatic experience into the autobiographical memory results in typical symptoms associated with post-traumatic stress disorder (PTSD) such as intrusive re-experiencing. Sleep supports the integration of new experiences into existing memory networks through memory consolidation. In fifty-six females, we investigated whether a 90-min daytime nap (n = 33) compared to a wake period (n = 23) after being exposed to an experimental trauma (i.e. a trauma film) prevents PTSD analogue symptoms. Intrusive memories were recorded for seven days using a diary, overall PTSD symptoms were assessed using the Impact of Event Scale (IES-R) and affective response to trauma cues were measured one week after experimental trauma. The two groups did not differ in any of the analogue PTSD symptoms. However, participants obtaining rapid eye movement (REM) sleep in the nap experienced less distressing intrusive memories. Moreover, the duration of REM sleep and slow wave activity was negatively correlated with analogue PTSD symptoms. Our findings suggest that even a short sleep period after experimental trauma can play a protective role in trauma memory formation but only if the nap contains REM sleep. Our data provide additional evidence for a critical role of REM sleep in PTSD development

Cholecystokinin Activates a Variety of Intracellular Signal Transduction Mechanisms in Rodent Pancreatic Acinar Cells

Cholecystokinin (CCK) acting through its G protein-coupled receptor is now known to activate a variety of intracellular signaling mechanisms and thereby regulate a complex array of cellular functions in pancreatic acinar cells. The best studied mechanism is the coupling through heterotrimeric G proteins of the G q family to activate a phospholipase C leading to an increase in inositol trisphosphate and release of intracellular Ca 2+ . This pathway along with protein kinase C activation in response to the increase in diacylglycerol stimulates the secretion of digestive enzymes by the process of exocytosis. CCK also activates signaling pathways in acini more related to other processes. The three mitogen activated protein kinase cascades leading to ERKs, JNKs and p38 MAPK are all activated by CCK. CCK activates the ERK cascade by PKC activation of Raf which in turn activates MEK and ERKs. JNKs are activated by a distinct mechanism whish requires higher concentrations of CCK. Both ERKs and JNKs are presumed to regulate gene expression. CCK activation of p38 MAPK also plays a role in regulating the actin cytoskeleton through phosphorylation of the small heat shock protein HSP27. The PI3K-PKB-mTOR pathway is activated by CCK and plays a major role in regulating protein synthesis at the translational level. This includes both activation of p70 S6K leading to phosphorylation of ribosomal protein S6 and the phosphorylation of the binding protein for initiation factor 4E leading to formation of the mRNA cap binding complex. Other signaling pathways activated by CCK receptors include NF-κB and a variety of tyrosine kinases. Further work is needed to understand how CCK receptors activate most of the above pathways and to better understand the biological events regulated by these diverse signaling pathways.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/72562/1/j.1600-0773.2002.910606.x.pd
