How do objective and subjective career success interrelate over time?

The present research is concerned with the direction of influence between objective and subjective career success. We conducted a prospective longitudinal study with five waves of measurement that covered a time span of 10 years. Participants were professionals working in different occupational fields (N=1,336). We modelled the changes in objective success (income, hierarchical position), in other-referent subjective success (subjective success as compared to a reference group), and in self-referent subjective success (job satisfaction) by means of latent growth curve analysis. Objective success influenced both the initial level and the growth of other-referent subjective success, but it had no influence on job satisfaction. Most importantly, both measures of subjective success and both their initial levels and their changes had strong influences on the growth of objective success. We conclude that the ‘objective success influences subjective success’ relationship is smaller than might be expected, whereas the ‘subjective success influences objective success’ relationship is larger than might be expected.

Hepeviridae: An expanding family of vertebrate viruses

The hepatitis E virus (HEV) was first identified in 1990, although hepatitis E-like diseases in humans have been recorded for a long time dating back to the 18th century. The HEV genotypes 1–4 have been subsequently detected in human hepatitis E cases with different geographical distribution and different modes of transmission. Genotypes 3 and 4 have been identified in parallel in pigs, wild boars and other animal species and their zoonotic potential has been confirmed. Until 2010, these genotypes along with avian HEV strains infecting chicken were the only known representatives of the family Hepeviridae. Thereafter, additional HEV-related viruses have been detected in wild boars, distinct HEV-like viruses were identified in rats, rabbit, ferret, mink, fox, bats and moose, and a distantly related agent was described from closely related salmonid fish. This review summarizes the characteristics of the so far known HEV-like viruses, their phylogenetic relationship, host association and proposed involvement in diseases. Based on the reviewed knowledge, a suggestion for a new taxonomic grouping scheme of the viruses within the family Hepeviridae is presented.

Prevalence and Risk Factors for Therapy Escalation in Ulcerative Colitis in the Swiss IBD Cohort Study.

BACKGROUND Physicians traditionally treat ulcerative colitis (UC) using a step-up approach. Given the paucity of data, we aimed to assess the cumulative probability of UC-related need for step-up therapy and to identify escalation-associated risk factors. METHODS Patients with UC enrolled into the Swiss IBD Cohort Study were analyzed. The following steps from the bottom to the top of the therapeutic pyramid were examined: (1) 5-aminosalicylic acid and/or rectal corticosteroids, (2) systemic corticosteroids, (3) immunomodulators (IM) (azathioprine, 6-mercaptopurine, methotrexate), (4) TNF antagonists, (5) calcineurin inhibitors, and (6) colectomy. RESULTS Data on 996 patients with UC with a median disease duration of 9 years were examined. The point estimates of cumulative use of different treatments at years 1, 5, 10, and 20 after UC diagnosis were 91%, 96%, 96%, and 97%, respectively, for 5-ASA and/or rectal corticosteroids, 63%, 69%, 72%, and 79%, respectively, for systemic corticosteroids, 43%, 57%, 59%, and 64%, respectively, for IM, 15%, 28%, and 35% (up to year 10 only), respectively, for TNF antagonists, 5%, 9%, 11%, and 12%, respectively, for calcineurin inhibitors, 1%, 5%, 9%, and 18%, respectively, for colectomy. The presence of extraintestinal manifestations and extended disease location (at least left-sided colitis) were identified as risk factors for step-up in therapy with systemic corticosteroids, IM, TNF antagonists, calcineurin inhibitors, and surgery. Cigarette smoking at diagnosis was protective against surgery. CONCLUSIONS The presence of extraintestinal manifestations, left-sided colitis, and extensive colitis/pancolitis at the time of diagnosis were associated with use of systemic corticosteroids, IM, TNF antagonists, calcineurin inhibitors, and colectomy during the disease course.

Fas ligand and soluble Fas -opposing molecules in melanoma lung metastasis

Deregulation of apoptotic cell death can result in aberrant accumulation of cells and increased tumor incidence. Fas (CD95) and Fas ligand (FasL) are a receptor-ligand pair whose activation induces apoptosis in many cell types. Previously, we demonstrated that low metastatic, Fas+ K1735-P murine melanoma cells spontaneously metastasize to the lung following orthotopic injection into FasL-deficient (gld) mice compared to wild-type (wt) controls. We further demonstrated that the expression of the Fas antagonist soluble Fas (sFas) directly correlates with disease stage in patients with melanoma, breast, and colon cancer. These findings document a role for host-derived FasL, in the control of metastatic disease and suggest a role for tumor-associated sFas in acquiring metastatic potential. To directly test whether FasL expressed on lymphocytes or on lung stromal cells restricts metastasis, bone marrow chimeras were generated between C3H wt and C3H gld mice. Chimeric animals were injected subcutaneously with 5 × 105 K1735-P and the incidence and number of spontaneous lung metastases scored. The data show that wt mice receiving gld marrow had a greater number of lung metastases (median 9.5, range 2–31) than gld mice reconstituted with wt marrow (median 1, range 0–31; p < 0.016). Interestingly, both groups had fewer metastases compared to gld controls (median 18.5, range 0–46) but more than wt controls (median 2, range 0–7). These observations provide the first evidence that both hematopoietic- and nonhematopoietic-host derived FasL, are important in the control of melanoma metastasis to the lung. To directly test whether tumor-associated sFas expression can enhance metastasis, K1735-P cells were transfected with three isoforms of sFas (Exo4Del, Exo6Del, and Exo3, 4, 6Del). RT-PCR and ELISA analysis confirmed the expression of sFas RNA and protein respectively. Following intravenous injection of 5 × 104 cells, sFas transfected cells formed significantly more experimental lung metastases [Exo6Del clone 3 (median 22, range 0–36), Exo6Del clone 7 (median 31, range 4–50), Exo3, 4, 6Del (median 22.5, range 13–48)] compared to vector control cells (median 6.5, range 3–29). Together, these data provide the first evidence that sFas is sufficient to enhance the metastatic potential of Fas+ melanoma cells. ^

Horizontal profiles of longwave and shortwave radiation components over sea ice near Barrow, Alaska during the 2011 melt

An integrated instrument package for measuring and understanding the surface radiation budget of sea ice is presented, along with results from its first deployment. The setup simultaneously measures broadband fluxes of upwelling and downwelling terrestrial and solar radiation (four components separately), spectral fluxes of incident and reflected solar radiation, and supporting data such as air temperature and humidity, surface temperature, and location (GPS), in addition to photographing the sky and observed surface during each measurement. The instruments are mounted on a small sled, allowing measurements of the radiation budget to be made at many locations in the study area to see the effect of small-scale surface processes on the large-scale radiation budget. Such observations have many applications, from calibration and validation of remote sensing products to improving our understanding of surface processes that affect atmosphere-snow-ice interactions and drive feedbacks, ultimately leading to the potential to improve climate modelling of ice-covered regions of the ocean. The photographs, spectral data, and other observations allow for improved analysis of the broadband data. An example of this is shown by using the observations made during a partly cloudy day, which show erratic variations due to passing clouds, and creating a careful estimate of what the radiation budget along the observed line would have been under uniform sky conditions, clear or overcast. Other data from the setup's first deployment, in June 2011 on fast ice near Point Barrow, Alaska, are also shown; these illustrate the rapid changes of the radiation budget during a cold period that led to refreezing and new snow well into the melt season.
