Claudio Caviezel, Philipp Schuetz, Stephan Gerdes, Franco Gambazzi
BACKGROUND: The optimal time point for surgical management of advanced parapneumonic empyema in need of open pleurectomy and decortication remains unclear. We hypothesized that surgical outcomes will be better when procalcitonin (PCT) levels have dropped to normal ranges as evidence for resolution of the underlying pneumonia. METHODS: We retrospectively analyzed outcomes of 38 patients with advanced parapneumonic empyema who underwent open decortication and pleurectomy with available preoperative PCT (pPCT) values...

Socioeconomic status (SES) is associated with childhood anthropometry, but little is known about how it is associated with tissue growth and body composition. To investigate this, we looked at components of SES at birth with growth in early and mid-childhood, and body composition in a longitudinal study in Nepal. The exposure variables (material assets, land ownership, and maternal education) were quantified from questionnaire data before birth. Anthropometry data at birth, 2.5 and 8.5 years, were normalized using WHO reference ranges and conditional growth calculated...

Calmodulin (CaM) functions depend on interactions with CaM-binding proteins, regulated by Ca2+. Induced structural changes influence the affinity, kinetics, and specificities of the interactions. The dynamics of CaM interactions with neurogranin (Ng) and the CaM-binding region of Ca2+/calmodulin-dependent kinase II (CaMKII290-309 ) have been studied using biophysical methods. These proteins have opposite Ca2+ dependencies for CaM binding. Surface plasmon resonance biosensor analysis confirmed that Ca2+ and CaM interact very rapidly, and with moderate affinity ( KDSPR=3μM)...

BACKGROUND: Malignant pleural mesothelioma is a rare tumor with a dismal prognosis, usually presenting with recurrent effusions. However, the majority of malignant pleural effusions are due to lung adenocarcinoma (AdC). The distinction between these tumors has considerable therapeutic and medicolegal implications and can be very challenging both histologically and cytologically. Appropriate immunohistochemistry (IHC) is required to support the diagnosis. MicroRNA (miRNA) expression analysis could be a viable diagnostic tool for distinguishing between these tumors...

The friction cost approach has been proposed as an alternative to the human capital approach in estimating productivity costs. However, it is difficult, in practice, to apply this approach due to limited availability of context-specific data. Using national and firm-level data on vacancy durations sourced from 4 organisations, we estimated vacancy durations, and consequently, length of friction period for the United Kingdom disaggregated by occupational classification. We found comparable estimates to previously reported friction periods elsewhere...

G protein-coupled receptors (GPCRs) play an important role for many cellular responses, and as such their mechanism of action is of utmost interest. To gain insight into the active conformation of GPCRs, the X-ray crystal structures of Nanobody(Nb)-stabilized β2-adrenergic receptor (β2AR) have been reported. Nb80 in particular is able to bind the intracellular G protein binding site of β2AR and stabilize the receptors in an active conformation. Within Nb80, the complementarity-determining region 3 (CDR3) is responsible for most of the binding interactions...

Studies that have evaluated the prognostic value of body mass index (BMI) in patients with diffuse large B-cell lymphoma have recently been reported. However, the impact of BMI on survival outcomes remains controversial. We retrospectively analyzed the data of 406 diffuse large B-cell lymphoma patients treated with R-CHOP or R-CHOP-like regimens. The number (%) of patients that were categorized into 1 of 4 groups according to BMI were underweight (<18.5 kg/m(2) ), 58 (14.3%); normal weight (≥18.5 to <25 kg/m(2) ), 262 (64...

Population genetic data from multiple taxa can address comparative phylogeographic questions about community-scale response to environmental shifts, and a useful strategy to this end is to employ hierarchical co-demographic models that directly test multi-taxa hypotheses within a single, unified analysis while benefiting in statistical power from aggregating datasets. This approach has been applied to classical phylogeographic datasets such as mitochondrial barcodes as well as reduced-genome polymorphism datasets that can yield 10,000s of SNPs, produced by emergent technologies such as RAD-seq and GBS...
