Synaptic vesicle (SV) release is spatially and temporally regulated by a network of proteins that form the presynaptic active zone (AZ). The hallmark of most AZs is an electron-dense projection (DP) surrounded by SVs. Despite their importance for our understanding of triggered SV release, high-resolution analyses of DP structures are limited. Using electron microscopy, we show that DPs at Caeno...

AIMS This research sought (a) to investigate the similarities and differences in how pharmaceutical services are provided by community pharmacies (CPs) and dispensing doctor practices (DPs) and (b) to identify the issues relevant to determining the quality of pharmaceutical services in these settings. BACKGROUND UK pharmaceutical services, including dispensing prescriptions and public health ...

Since the adoption of Abney’s (1987) influential proposal that noun phrases are (at most) DPs, the hypothesis that not all noun phrases in all languages are DPs has been widely debated. A particularly interesting case in this respect is presented by Slavic languages lacking overt articles such as Russian or Serbo-Croatian: are noun phrases in such languages ever DPs, always DPs, or sometimes DP...

Currently valid itch intensity scales, such as the visual analogue scale (VAS), are indispensable, but they can be influenced by the patient's overall health status. The aim of this study was to evaluate the reliability and validity of the Dynamic Pruritus Score (DPS), a new instrument comparing reduction in current pruritus with a defined earlier time-point. Eighty-one randomly selected adults...

Resistance to phagocyte-derived reactive oxygen species is essential for Salmonella enterica serovar Typhimurium pathogenesis. Salmonella can enhance its resistance to oxidants through the induction of specific genetic pathways controlled by SoxRS, OxyR, sigma(S), sigma(E), SlyA, and RecA. These regulons can be found in a wide variety of pathogenic and environmental bacteria, suggesting that ev...

Finding motifs and the corresponding binding sites is a critical and challenging problem in studying the process of gene expression. String and matrix representations are two popular models to represent a motif. However, both representations share an important weakness by assuming that the occurrence of a nucleotide in a binding site is independent of other nucleotides. More complicated represe...

OBJECTIVE To evaluate the effects of functional electrical stimulation (FES) to ankle dorsiflexor (DF) and ankle plantarflexor (PF) on kinematic and kinetic parameters of hemiplegic gait. METHODS Fourteen post-stroke hemiplegic patients were considered in this study. Electrical stimulation was delivered to ankle DF during the swing phase and ankle PF during the stance phase via single foot sw...

In this paper, we propose the use of a control theoretical approach in the design of fair queueing algorithms based on the Scalable Core (SCORE) / Dynamic Packet State (DPS) architecture. In particular, we make use of the Linear Quadratic control method from optimal control theory to design stable and robust systems that are simple to implement. Simulation results show that this approach gives ...

We experienced two cases of left ventricular free wall rupture (LVFWR) following acute myocardial infarction (AMI). Case 1, with the blowout type of LVFWR was initially closed by direct suture, followed by hemostasis using a double patch sealing method (DPS) by which the tear was doubly sealed with large and small bovine pericardium patches to which GRF glue was applied. Case 2 with the oozing ...

The review outlines the experimental studies that have led to the current understanding at a molecular level of the protective role exerted by Dps proteins under stress conditions. After a brief description of the structural signatures and of the ferroxidase activity, which confers to all Dps proteins the capacity to decrease the hydroxyl radical induced DNA damage, the interaction of some fami...
