LC-MS Approaches to Profiling of Non-Radiolabelled Metabolites in Response to Recent Regulatory Changes
Richard Clayton, Caroline Anderson, Brian Morrison and Lindsay Corfield

Following publication of the FDA MIST guidelines and revision of ICH M3, there is increasing interest in obtaining metabolic profiling data at an early stage in the development of a drug. This has led to a requirement to estimate the relative abundance of metabolites in samples prior to the synthesis of the radiolabelled compound and from a wider range of studies.

Fast PK and Semi Quantitative Analysis of Metabolites Using High Resolution MS
Rohan A. Thakur and Mike Koleto

It has become essential to eliminate poor candidates as early as possible in the drug development process. This realization led to the application of high throughput principles to the in vivo Lead Optimization process, wherein the NCE is first given to rodents to determine the PK profile in a rapid and limited study. This rapid primary screen is known as Fast PK and several critical decisions are based on this initial study.

How to Produce and Validate an IND Report / Validation Report in Just a Few Days
Dr Paul Denny-Gouldson, Simon Beaulah

How to Produce and Validate an IND Report / Validation Report in Just a Few Days The IDBS E-WorkBook Suite is an enterprise, data-centric ELN designed to support validated experiment data and IP capture for the entire large and small molecule preclinical development environment. It enables data required for experiments and reports to be captured, stored and searched in a consistent manner across all departments.

Tobacco use in asbestos workers
T.Medveczky, C.Turton

Asbestos related lung disease is likely to increase. Smoking, apart from being the major risk factor for lung cancer, may be a co-factor in the development of asbestos in lung disease. The Health and Safety Executive report mentions the high rate of smokers in asbestos related industry (1). We have reviewed our local population of asbestos workers to explore that further.

Homing of bone marrow derived mononuclears after intracoronary transventricular transplantation
Homing of bone marrow derived mononuclears after intracoronary transventricular transplantation

A new method of administration of bone marrow derived mononuclear cells (BMMCs) was studied using the model of acute myocardial infarction in rats. The transplanted cells were detected only in the scar tissue and had fibroblast-like phenotype. They differentiated neither into cardiomyocytes nor into the cells of blood vessels.

Protein array-based screening of autoantibody signatures
Zingaretti C., Arigò M., Colombatto P., Brunetto M., Muratori L., Bonino F., Bianchi F., Pagani M., De Francesco R., Abrignani S., Bombaci M.

The evidence for an association between autoimmune diseases and chronic HCV infection has been clearly established. To this aim, a protein array was employed to analyze serum samples of HCV patients w/wo autoimmune complications, of patients with autoimmune hepatitis but not infected with HCV and of healthy donors as controls. A panel of autoantigens able to discriminate among the three groups of patients was identified for potential use as biomarkers.

Clinical Evaluation of induced pluripotent stem cells (iPSc) to cure patients with Psoriasis Vulgaris. An Open Study.
Timothy S. Andersson, David K. Chin, Wendy H. Wong

To evaluate the clinical efficacy of iPSc directed to interfere T-cell activation to cure patients with psoriasis. Twenty subjects were enrolled. Each patient was administered iv with syngenic iPS. Those showing lower PASI score were considered cured. The study states that induced iPSCs are safe and impart significant clinical efficacy to cure patients with psoriasis.

Ethnicity and Help-seeking
Kyle L. Gravel¹, Christina J. Sun², Nana Sadamura¹, Erin Moniz¹

Ethnic minorities have traditionally underutilized mental health services. It has been proposed that both willingness to see a counselor and attitudes towards seeking psychological help may impact utilization of psychological services among ethnic minority populations. The aim of this study was to explore the relationship between willingness to see a counselor and attitudes toward seeking psychological help among college students.

Clinical Outcomes and Emerging Challenges after 5 years of ART in Khayelitsha, South Africa
Gilles Van Cutsem1, Katherine Hilderbrand1,2, David Coetzee2,3, Carol Cragg3, Eric Goemaere1 & Andrew Boulle2,3

One of the first primary care antiretroviral treatment programs in Africa shows good patient outcomes at 5 years. Saturation of services has led to increased losses to follow-up.
