Receptor protein tyrosine phosphatases (RPTPs) control many aspects of nervous system development. At the Drosophila neuromuscular junction (NMJ), regulation of synapse growth and maturation by the RPTP LAR depends on catalytic phosphatase activity and on the extracellular ligands Syndecan and Dally-like. We show here that the function of LAR in controlling R7 photoreceptor axon targeting in th...

Vehicular ad-hoc network (VANET) is an integral component of intelligent transportation systems. Due to continuous movement of vehicles, network formation and deformation is very frequent. Furthermore, for safety applications, we wish to create the communication without any delay or collision. Therefore, communication among the vehicles is even more challenging. D-LAR (Directional– Location Aid...

Synaptic adhesion molecules regulate diverse aspects of synapse development and plasticity. SALM3 is a PSD-95-interacting synaptic adhesion molecule known to induce presynaptic differentiation in contacting axons, but little is known about its presynaptic receptors and in vivo functions. Here, we identify an interaction between SALM3 and LAR family receptor protein tyrosine phosphatases (LAR-RP...

This study aims to compare economic and patient impacts of the treatment of acromegaly with two different somatostatin analogues (octreotide LAR and lanreotide SR) in Brazil. A cost-effectiveness analysis was carried out under the Brazilian Public Health Care System (SUS) perspective. A decision analytical model was developed based on the Brazilian Public Health Care System Clinical Guideline f...

Recently, we have shown that allergen-induced airway hyperresponsiveness (AHR) after the early (EAR) and late (LAR) asthmatic reaction in guinea pigs could be reversed acutely by inhalation of the Rho kinase inhibitor Y-27632. The present study addresses the effects of pretreatment with inhaled Y-27632 on the severity of the allergen-induced EAR and LAR, the development of AHR after these react...

This paper provides a summary of our research study of the location-aided routing protocols for mobile ad hoc networks (MANET). This study focuses on the issue of using geographical location information to reduce the control traffic overhead associated with the route discovery process of the ad-hoc on demand distance vector (AODV) routing protocol. AODV performs route discovery by flooding the ...

Background Gastrointestinal angiodysplasias (GIADs) could be responsible for recurrent bleeding and severe anemia. Somatostatin analogs could reduce transfusion requirements in these patients but no randomized controlled study is available. The main objective of the ANGIOPAS phase II double-blinded randomized, noncomparative study was to assess the effectiveness of pasireotide-LAR in reducing t...

Morbidity and mortality rates in patients with active acromegaly are higher than the general population. Adequate biochemical control restores mortality to normal rates. Now, medical therapy has an increasingly important role in the treatment of patients with acromegaly. Somatostatin receptor ligands (SRLs) are considered the standard medical therapy, either after surgery or as a first-line the...

In this report, we compare the function of the human beta-globin locus control region (LCR) in three K562 erythroleukemia cell assays, including (1) a transient transfection assay for "classical" enhancer activity, (2) a colony assay that detects "productive integration events," and (3) an assay that detects the ability of LCR fragments to confer hemin inducibility on linked, stably integrated ...

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 ...
