Genetic toxicology data have traditionally been employed for qualitative, rather than quantitative evaluations of hazard. As a continuation of our earlier report that analyzed ethyl methanesulfonate (EMS) and methyl methanesulfonate (MMS) dose-response data (Gollapudi et al., 2013), here we present analyses of 1-ethyl-1-nitrosourea (ENU) and(More)
The principal goal of this study was to determine whether the results from a set of selected currently available alternative methods as used by cosmetics companies are valid for predicting the eye irritation potential of cosmetics formulations and ingredients and, as a consequence, could be valid replacements for the Draize eye irritation test. For the(More)
OBJECTIVE To report our clinical experience and 5-year prostate-specific antigen (PSA) relapse-free survival rate for early-stage prostate cancer after (125)I low-dose-rate prostate brachytherapy. PATIENTS AND METHODS In all, 300 patients were treated between March 1999 and April 2003, and followed prospectively. Patients were stratified into low-,(More)
Variation in mandible shape has been investigated in a set of recombinant inbred (RI) lines of mice, the C57BL/6J X A/J (BXA;AXB) RI lines. Considerable genetic variation was detected between the RI lines, but most lines were intermediate in shape when compared with the parent lines. Variation in mandible shape could not be explained by any single gene(More)
A wide range of experimental designs are used in investigations using the Comet assay. The statistical issues associated with this assay are however not particularly unusual or difficult. It is important however to recognize that the sample rather than the cell is the experimental unit. Statistical analyses based upon measures from the individual cells can(More)
BACKGROUND Adhesion formation is common after abdominal surgery. This study aimed to compare the extent of adhesion formation following laparoscopic and open colorectal surgery. METHODS An observational study was undertaken to identify adhesions in patients undergoing laparoscopy after previous laparoscopic or open colectomy. Adhesions were scored(More)
PURPOSE Recent studies have confirmed the clinical efficacy of laparoscopic colorectal surgery; however, its use has not become widespread. One reason for this is perceived economic implications. A systematic review was undertaken examining the costs of laparoscopic colorectal surgery. METHODS Electronic databases were searched for articles comparing(More)
OBJECTIVE To investigate the factors that may affect antibody titres to heat shock proteins (Hsp)-60, -65 and -70, and serum C-reactive protein (CRP) concentrations in patients with dyslipidaemia and other features of the metabolic syndrome as defined by ATPIII criteria. MATERIAL AND METHODS The study comprised 237 dyslipidaemia patients and 135 healthy(More)
