Compound precoding is a state-of-the-art technique for combining trellis coding and decision-feedback equalisation (DFE) prior to upstream transmission on the telephone-line channel, and is an option in the International Telecommunications Union (ITU)-T V.92 standard. In this paper, we provide a detailed overview of this technique. We demonstrate that compound precoding combines in a straightfo...

normal hemostasis requires balanced regulation of prothrombotic and antithrombotic factors. inherited alteration of factor v and prothrombin gene, the g20210a mutation, increases the resistance of factor v to degradation and booster production of prothrombin respectively. these alterations can increase hypercoagulability leading to thrombotic consequences. we aimed to assess the frequencies of ...

A fractions obtained from the culture fluids of a seven fungal species identified as Verticillium albo-atrum; V. lecanii; V. bulbillosum; V. dahliae; Fusarium solani; F. oxysporum, and Aspergillus sclerociarum were shown to contain a compounds with a biological activity against twenty two clinical bacterial strains including eleven isolates of gram positive and other were gram negative. Among t...

Celangulin V (CV), one of dihydroagarofuran sesquiterpene polyesters isolated from Chinese bittersweet (Celastrus angulatus Maxim), is famous natural botanical insecticide. Decades of research suggests that is displays excellent insecticidal activity against some insects, such as Mythimna separata Walker. Recently, it has been validated that the H subunit of V-ATPase is one of the target protei...

A polyoxapolyaza heteroditopic macrobicyclic compound (btpN(4)O(3)) was synthesized. The acid-base behaviour of the compound as well as its binding ability for zwitterionic amino acids were studied by potentiometry at 298.2 ± 0.1 K in H(2)O-MeOH (50:50 v/v) and at I = 0.10 ± 0.01 M in NMe(4)TsO. The H(n)btpN(4)O(3)(n+) showed preference for amino acids containing tetrahedral anionic groups.

OBJECTIVES We have previously identified the pyranodipyrimidines (PDPs) as a new class of integrase (IN) inhibitors. The most potent congener V-165 inhibits HIV-1 integration at low micromolar concentrations by inhibiting the binding of IN to the DNA. As part of pre-clinical studies with PDP, we wanted to investigate HIV resistance development against V-165 and to further characterize the physi...

Maoecrystal V is a highly oxidized and rearranged norterpenoid isolated from the Chinese herb, Isodon eriocalyx. A synthetic route for C/D/E-ring core compound of maoecrystal has been developed. Introduction C1 fragment to D/E-ring was achieved by lithito dithiane attack, C-ring formed deprotective intramolecular hemiacetalization dithiane-alcohol precursor.
