Reflecting the multiple ambiguities of its ordinary language use, the current scholarly use of the term(s) “medium”/“media” is fraught with contradictions. Starting out from the insight that the nucleus of any kind of communication is an act, in which an addresser presents an artefact and a task of interpretation to an addressee, which the latter is called upon to fulfil, anything else that accrue

Offspring sex ratios may deviate from parity when the fitness benefits of producing male or female offspring vary. We tested for sex ratio bias in smooth-billed anis Crotophaga ani, a communal laying cuckoo with low within-group relatedness and high offspring dispersal. One male group member performs nocturnal incubation and sires more offspring than other males in the group, suggesting males may

Objectives: Depression is common but not always recognized and often undertreated among elderly. Cardiovascular diagnoses have been reported to be associated with depression. The study examined if this association could be confirmed in a frail elderly population. It also assessed the association between high depressive scores and certain health complaints and the use of certain drugs, respectively

Right-wingauthoritarianism (RWA) is regularly implicated as a potential risk factor of abusive behavior, whereas social dominance orientation (SDO) is not. We compared RWA and the two subscales of SDO, SDO-Dominance and SDO-Egalitarianism, as factors behind legitimization and hypothetical self-involvement in the use of torture-like abusive behavior (a scenario from Abu-Ghraib military prison). Int

A high frequency of IgA1-positive tumour cells was found in tissue micro-arrays of oesophagus, colon, testis, lung, breast, bladder and ovarian cancer. IgA1 was observed in the cytoplasm and the plasma membrane. A correlation was found between intra-tumour IgA1 and poor overall survival in a large cohort of bladder cancer patients (n = 99, p = 0.011, log-rank test). The number of IgA1-positive tum

Chemerin is a recently discovered adipokine shown to be involved in both inflammatory and metabolic processes. Here, we demonstrate that chemerin serum levels are elevated in patients with multiple myeloma and that it increases with disease progression. We found that chemerin is expressed by stromal cells and preadipocytes, whereas its receptor CCRL2 is expressed by primary myeloma cells, suggesti

Gastroparesis is a well-known complication of diabetes mellitus, both in symptomatic and asymptomatic patients. Esophageal dysmotility has also been described, but is not as well-characterized. The etiology and effect of these complications need to be clarified. The aim of the present study was to evaluate esophageal and gastric motility, complications, gastrointestinal symptoms, and plasma biomar

En analys av komediserien Seinfeld där jag söker efter postmoderna tendenser i handling, manus och karaktärer för att besvara min frågeställning: Vad är identitet enligt Seinfeld som TV-serie?

The present communication reviews reasons to perform rescreening of chlamydia-infected persons. It brings up difficulties to differentiate between relapse and reinfection. Studies on follow-up of chlamydia-positive cases after therapy are reviewed. It also highlights reasons for therapeutic failure, like compliance, pharmacological factors, including poor bioavailability, wrong dose regimens, lack

Glucose-evoked insulin secretion exhibits a biphasic time course and is associated with accelerated intracellular granule movement. We combined live confocal imaging of EGFP-labelled insulin granules with capacitance measurements of exocytosis in clonal INS-1 cells to explore the relation between distinct random and directed modes of insulin granule movement, as well as exocytotic capacity. Reduci

The role of hybridization in evolution has been debated for more than a century regarding bryophytes (mosses, liverworts, and hornworts) as well as most other organisms. Bryophytes have haplodiplontic life cycles with a dominant haploid generation. Hybridization in bryophytes involves fusion of gametes produced by haploid parental gametophytes of different species. The hybrid is thus the short-liv

Given the polarized political context in Peru that was provoked by the inclusion of LGTBIQ+ identities in the official school curriculum, this study analyzes the meanings that students of pedagogy in Lima ascribe to tolerance and respect towards gay and lesbian people, and how these meanings inform their pedagogical practices. Based on two focus groups and eight individual interviews grounded in s

The diagnosis of malignant mesothelioma in serosal effusions continues to he a major challenge because some of its cytomorphological features closely resemble adenocarcinomas. Immunohistochemistry is a valuable tool in the differentiation of epithelioid mesothelioma from metastatic adenocarcinomas. However, no single antibody has demonstrated absolute sensitivity or specificity. In this study, we
