This study characterizes the interactions between kabiramide C (KabC) and related macrolides actin establishes mechanisms that underlie their inhibition of filament dynamics cytotoxicity. The G-actin–KabC complex is formed through a two-step binding reaction extremely stable long-lived. Competition-binding studies show KabC binds to same site on G-actin as Gelsolin domain 1 CapG. also protomers within F-actin results in severing capping (+) end; these suggest free act biomimetics Gelsolin....

Abstract An accurate and simple immunoassay using capillary electrophoresis (CE) with laser‐induced fluorescence (LIF) was performed for the detection of methamphetamine (MA) in urine. The CE‐LIF conducted an untreated fused‐silica column antiserum a tracer fluorescein isothiocyanate (FITC)‐labeled MA. This system compared polarization (FPIA) TDx analyzer photo‐check mode same FITC‐labeled antiserum. Various antibodies, not only those prepared by our own immunogens but also from commercial...

With the advancement of artificial intelligence, methods for generating audio deepfakes have improved, but technology behind it has become more complex. Despite this, non-expert users are able to generate due increased accessibility latest technologies. These technologies can be used support content creators, singers, and businesses such as advertisement or entertainment industries. However, they also misused create disinformation, CEO fraud, voice scams. Therefore, with increasing demand...

A gas chromatography/mass spectrometry method is described which uses negative ion chemical ionization and tandem mass for the determination of anabolic steroid metabolites. Four metabolites to be derivatized by Pentafluoropropionic anhydride (PFPA) were determined using (GC/MS) with (NCI) NCI/MS/MS. The repeatability reproducibility this procedure in range 5.3–9.7% 6.1–10.2%, respectively. This derivatization PFPA NCI NCI/MS/MS was useful determine four nandrolone, dromostanolone,...

A homogeneous fluorescence polarization immunoassay (FPIA) was developed to measure levels of progesterone in urine using a TDx analyzer photocheck mode (Abbott Labs). Two tracers ethylenediamine fluorescein thiocarbamyl (EDF) were employed; one synthesized from 11 alpha-hydroxyhemisuccinate (Prog-11OH-HS) and the other 3-(o-carboxymethyl)oxime (Prog-3CMO). Each derivative conjugated with bovine serum albumin used as an immunogen which produced monoclonal antibody clone 15A (MAb 15A,...
