The objective of this study was to detect the presence of acyl homoserine lactones (AHLs), signal molecules of the quorum sensing system in biofilm formed by Hafnia alvei strains. It also evaluated the effect of synthetic quorum sensing inhibitors in biofilm formation. AHLs were assayed using well diffusion techniques, thin layer chromatography (TLC) and detection directly in biofilm with biomo...

Abstract Study question Does supplementation of human sperm media with L-Proline improve function and chromatin quality during in Vitro Incubation? Summary answer The inclusion L-proline as an antioxidant improves integrity probably by modulating oxidative stress What is known already Infertility affects millions people reproductive age globally. gametes one the most critical aspects that could...

Kidney transplantation today has excellent short-term outcomes that have paralleled the use of new immunosuppressive agents introduced in the 1990s. In addition to reducing acute rejection, the goals for developing new agents is to improve long-term outcome, minimize nephrotoxicity, and reduce infectious, cardiovascular, and malignancy-related complications. Novel small molecules and biological...

The high-resolution spectrum of water vapor between 13 200 and 16 500 cm-1 recorded by J.-Y. Mandin, J-P. Chevillard, C. Camy-Peyret, J.-M. Flaud, and J. W. Brault (1986. J. Molec. Spectrosc., 116, 167) is analyzed using high-accuracy linelists obtained using ab initio calculations and spectroscopically determined potential. Assignments to H216O transitions are presented for 663 of the 795 unas...

We study the parallel computation of dynamic programming. We consider four important dynamic programming problems which have wide application, and that have been studied extensively in sequential computation: (1) the 1D problem, (2) the gap problem, (3) the parenthesis problem, and (4) the RNA problem. The parenthesis problem has fast parallel algorithms; almost no work has been done for parall...

We report the discovery of a several-Jupiter mass planetary companion to the primary lens star in microlensing event OGLE-2005-BLG-071. Precise (. 1%) photometry at the peak of the event yields an extremely high signal-to-noise ratio detection of a deviation from the light curve expected from an isolated lens. The planetary character of this deviation is easily and unambiguously discernible fro...

By its very nature, a non-authenticated multi-party key agreement protocol cannot provide participant and message authentication, so it must rely on an authenticated network channel. This paper presents the inability of two famous multi-party key agreement protocols to withstand malicious participant attacks, even though their protocols are based on the authenticated network channel. This attac...
