BACKGROUND Extended gastrectomy with para-aortic nodal dissection (PAND) or thorough dissection of mediastinal nodes using a left thoracoabdominal (LTA) approach is an alternative to D2 lymphadenectomy, with variable postoperative results. METHODS Two randomized controlled trials have been conducted to compare D2 lymphadenectomy alone (263 patients) versus D2 lymphadenectomy plus PAND (260), ...

LTA is a lightweight trust architecture that fights phishing attacks by authenticating e-mail messages. LTA uses separable identity-based ring signatures, which are more attractive than traditional digital signatures for e-mail signing. Because the signatures are identity-based, users do not need to generate keys ahead of time. And because the ring signatures are repudiable, users do not need t...

This paper discussed the synthesis of LTA zeolite from Pinheiro clay (PIN) aiming for adsorption CO2. To obtain LTA-PIN zeolite, PIN was submitted to acid treatment, followed by calcination and hydrothermal treatment. These treatments promoted reorganization crystalline structure PIN, leading with 95.79% purity confirmed XRD, SEM, XRF, FTIR results. The performance similar one standard zeolite....

Lipoteichoic acids (LTA) are amphiphilic polymers that are important constituents of the cell wall of many Gram-positive bacteria. The chemical structures of LTA vary among organisms, albeit in the majority of Gram-positive bacteria the LTAs feature a common poly-1,3-(glycerolphosphate) backbone. Previously, the specificity of opsonic antibodies for this backbone present in some Gram-positive b...

BACKGROUND Churg-Strauss syndrome (CSS) is a rare granulomatous small vessel vasculitis that occurs against a background of longstanding asthma. Leukotriene antagonists (LTAs) are used in the management of asthma and may facilitate a reduction in steroid dosage. Reports of the development of CSS in patients with asthma following the initiation of LTA therapy suggest either a causal association ...

The insertional inactivation of the dlt operon from Lactobacillus plantarum NCIMB8826 had a strong impact on lipoteichoic acid (LTA) composition, resulting in a major reduction in D-alanyl ester content. Unexpectedly, mutant LTA showed high levels of glucosylation and were threefold longer than wild-type LTA. The dlt mutation resulted in a reduced growth rate and increased cell lysis during the...

OBJECTIVE The aim of this meta-analysis is to evaluate associations between LTA-252 A>G and breast cancer (BC). METHODS Electronic searches of several databases were conducted for all online publications. A total of 7 studies involving 4,625 BC patients and 4,373 controls were identified. RESULTS This meta-analysis showed no significant association between the LTA-252 A>G polymorphism and B...

A novel architecture for winner-take-all (WTA) and looser-take-all (LTA) circuits is proposed. As compared with other realisations, the LTA does not require input subtraction from a reference, which decreases accuracy and input dynamics. The architectures have been designed using the gm/ID methodology. As it will be shown, this method allows a rapid new dimensioning when specifications are modi...

Peptidoglycan recognition proteins (PGRPs) are involved in the recognition of pathogen-associated molecular patterns. The well known pathogen-associated molecular patterns include LPS from Gram-negative bacteria and lipoteichoic acid (LTA) from Gram-positive bacteria. In this work, the crystal structures of two complexes of the short form of camel PGRP (CPGRP-S) with LPS and LTA determined at 1...

Lipoteichoic acid (LTA) is an important cell wall component required for proper cell growth in many Gram-positive bacteria. In Listeria monocytogenes, two enzymes are required for the synthesis of this polyglycerolphosphate polymer. The LTA primase LtaP(Lm) initiates LTA synthesis by transferring the first glycerolphosphate (GroP) subunit onto the glycolipid anchor and the LTA synthase LtaS(Lm)...
