OBJECTIVES To evaluate the radiation dose of the main body CT examinations performed routinely in four regional diagnostic centres, the specific contribution of radiologists and technologists in determining CT dose levels, and the role of radiological staff training in reducing radiation doses. METHODS We retrospectively evaluated the radiation dose in terms of dose-length product (DLP) value...

Amphibian skin secretions are an important treasure house of bioactive antimicrobial peptides (AMPs). Despite having been the focus of decades of research in this context, investigations of phyllomedusine frogs continue to identify new AMPs from their skin secretions. In this study, the prototype of a novel family of AMP distinctin-like-peptide-PH (DLP-PH) was identified from the skin secretion...

Hedgehog (Hh) acts as a morphogen in various developmental contexts to specify distinct cell fates in a concentration-dependent manner. Hh signaling is regulated by two conserved cell-surface proteins: Ig/fibronectin superfamily member Interference hedgehog (Ihog) and Dally-like (Dlp), a glypican that comprises a core protein and heparan sulfate glycosaminoglycan (GAG) chains. Here, we show in ...

Mitochondrial fission is mediated by dynamin-like proteins (DLPs). Trypanosoma brucei contains a single DLP, which is the only member of the dynamin superfamily. We have previously shown that expression of the human proapoptotic Bax in T. brucei induces extensive mitochondrial fragmentation. Here we report that Baxinduced mitochondrial fission is abolished in cell lines lacking functional DLP s...

Description Logic Programs (DLP) have been described as a description logic (DL) that is in the “expressive intersection” of DL and datalog. This is a very weak guideline for defining DLP in a way that can be claimed to be optimal or maximal in any sense. Moreover, other DL fragments such as EL and Horn-SHIQ have also been “expressed” using datalog. So is DLP just one out of many equal DLs in t...

CMP aims at providing Universities, Research Laboratories and Industries with the possibility to have their integrated circuits projects fabricated for prototyping and low volume production. Presently, users are serviced for CMOS double layer poly/double layer metal (DLP/DLM) 0.8, DLM/TLM 0.6μ, DLP/4LM 0.35μ, SLP/6LM 0.25μ, SLP/6LM 0.18μ, BiCMOS DLP/DLM 0.8μ, SiGe HBT 0.8μ DLP/DLM, SiGe HBT 0.3...

In this paper we focus on the fabrication of individual plastic refractive microlenses with Deep Lithography with Protons (DLP). We give a detailed description of the microlens fabrication technique and the calibration procedure that goes along with it. We highlight the geometrical and optical characteristics of these DLP microlenses and we demonstrate the reproducibility of the fabrication pro...

The aim of this study is to provide artificial agents with logical tools to reason specifically on privacy-related regulations, in order to comply with them. In order to express these regulations, the Deontic Logic for Privacy (DLP) is proposed. DLP is a deontic and temporal logic based on predicates dealing with personal data management. Illustrated by an example, it becomes obvious that speci...

Numerous applications in important domains, such as communication, multimedia, etc. show a significant data-level parallelism (DLP). A large part of the DLP is usually exploited through application vectorization and implementation of vector operations in processors executing the applications. While the amount of DLP varies between applications of the same domain or even within a single applicat...

The formation and plasticity of synaptic connections rely on regulatory interactions between pre- and postsynaptic cells. We show that the Drosophila heparan sulfate proteoglycans (HSPGs) Syndecan (Sdc) and Dallylike (Dlp) are synaptic proteins necessary to control distinct aspects of synaptic biology. Sdc promotes the growth of presynaptic terminals, whereas Dlp regulates active zone form and ...
