In this paper, we show that beta COP is present on endosomes and is required for the formation of vesicles which mediate transport from early to late endosomes. Both the association of beta COP to endosomal membranes as well as transport vesicle formation depend on the lumenal pH. We find that epsilon COP, but not gamma COP, is also associated to endosomes, and that this association is also lum...

BACKGROUND The association of Kikuchi Fujimoto disease (KFD) with cryptogenic organizing pneumonia (COP) is extremely rare. We report a case of simultaneous diagnosis of KFD and COP. CASE PRESENTATION A 33-year-old male presented with a 1-month cough illness and fever lasting for 5 days. The chest radiograph revealed double lower lobe infiltrate, which was unresponsive to antibiotics. A cervi...

BACKGROUND One of the most restricting factors remaining in heart transplantation is the limited myocardial ischemia time. A new approach towards the prolongation of this time is the combination of primary cardioplegic arrest followed by continuous coronary oxygen persufflation (COP) with gaseous oxygen. METHODS This technique was applied in pig hearts, which we transplanted orthotopically af...

We consider k-cop-win graphs in the binomial random graph G(n, 1/2). It is known that almost all cop-win graphs contain a universal vertex. We generalize this result and prove that for every k ∈ N, almost all k-cop-win graphs contain a dominating set of cardinality k. From this it follows that the asymptotic number of labelled k-cop-win graphs of order n is equal to (1+o(1))(1−2−k)−k ( n k ) 2 ...

Background The aim of this study was to compare centre of pressure (COP) characteristics between healthy adults with normal, planus or cavus feet who were allocated to groups based on reliable foot posture measurement techniques. Methods Ninety-two healthy adult participants (aged 18 to 45) were recruited and classified as either normal (n = 35), pes planus (n = 31) or pes cavus (n = 26) base...

Communities of practice (CoP) can facilitate collaboration between people who share a common interest, but do not usually work together. A CoP was initiated and developed including stakeholders from clinical, research, community and governmental backgrounds involved in a large multidisciplinary and multi-sectorial project: the Rehabilitation Living Lab in a Mall (RehabMaLL). This study aimed to...

Eleven recessive mutant loci define the class of cop / det / fus mutants of Arabidopsis. The cop / det / fus mutants mimic the phenotype of light-grown seedlings when grown in the dark. At least four cop / det / fus mutants carry mutations in subunits of the COP9 signalosome, a multiprotein complex paralogous to the 'lid' subcomplex of the 26S proteasome. COP1, another COP/DET/FUS protein, is i...

OBJECTIVES To contrast the static balance in patients presenting diabetes mellitus type 2 (DM2) with and without polyneuropathy (DPN); and to correlate the rates from the scale Diabetic Neuropathy Examination (DNE) with the mean ratio of the center of pressure (CoP). SUBJECTS AND METHODS Twenty patients, aged between 40 and 54, presenting DM2 and classified, according to DNE scale, in groups ...

Recurrence quantification analysis (RQA) can extract the dynamics of postural control from center of pressure (CoP) data by quantifying the system's repeatability, complexity, and local dynamic stability through several variables. Computation of these variables requires the selection of suitable embedding parameters for state space reconstruction (i.e. time delay and embedding dimension); howev...

Sample entropy (SaEn), calculated for center of pressure (COP) trajectories, is often distinct for compromised postural control, e.g., in Parkinson, stroke, or concussion patients, but the interpretation of COP-SaEn remains subject to debate. The purpose of this paper is to test the hypotheses that COP-SaEn is related (Hypothesis 1; H1) to the complexity of the postural movement structures, i.e...
