An optimized lactate dehydrogenase release assay for screening of drug candidates in neuroscience.

Introduction: Quantification of lactate dehydrogenase (LDH) release is a widely accepted assay for the quantitative determination of cell viability and late-stage apoptosis. Major disadvantages of commercially available LDH assay kits include proprietary formulations, limited options for optimization and high cost, all resulting in limited reproducibility in research applications. Here, we describe a novel, custom LDH assay suitable in the context of plate reader-based screening of drug candidates for glioprotection, but with wide applicability to other cell types and experimental paradigms.

Vibronic coupling in the superoxide anion: the vibrational dependence of the photoelectron angular distribution.

We present a comprehensive photoelectron imaging study of the O(2)(X  (3)Σ(g)(-),v(')=0-6)←O(2)(-)(X  (2)Π(g),v(")=0) and O(2)(a (1)Δ(g),v(')=0-4)←O(2)(-)(X  (2)Π(g),v(")=0) photodetachment bands at wavelengths between 900 and 455 nm, examining the effect of vibronic coupling on the photoelectron angular distribution (PAD). This work extends the v(')=1-4 data for detachment into the ground electronic state, presented in a recent communication [R. Mabbs, F.

Immunoprophylactic effects of the anti-leprosy Mw vaccine in household contacts of leprosy patients: clinical field trials with a follow up of 8-10 years.

We report here a large scale, double blind immunoprophylactic trial of a leprosy vaccine based on Mycobacterium w (Mw) in an endemic area of Kanpur Dehat, Uttar Pradesh, India. A population of 420,823 spread over 272 villages was screened where 1226 multibacillary (MB) and 3757 paucibacillary (PB) cases of leprosy were detected. A total of 29,420 household contacts (HHC) of these patients were screened for evidence of active or inactive leprosy.
