The purpose of this study was to determine if a donor age effect exists for the frequency of aneuploidy and other chromosome abnormalities in human spermatozoa. Sperm samples were collected from 18 healthy men from the general population. Each individual belonged to one of six age groups (20-24, 25-29, 30-34, 35-39, 40-44, > or = 45 years) with three men in each group. Two multicolour fluoresce...

Objective: To examine the validity of a semi-quantitative food frequency questionnaire (SFFQ) to identify dietary patterns in an adult Mexican population. Materials and methods: A 140-item SFFQ and two 24-hour dietary recalls (24DRs) were administered. Foods were categorized into 29 food groups used to derive dietary patterns via factor analysis. Pearson and intraclass correlations coefficien...

The objective of this study was to evaluate sire breed effect on mineral concentration in beef longissimus thoracis (LT) and investigate the correlations between beef mineral concentrations and carcass and palatability traits. Steer progeny (N=246) from the Germplasm Evaluation project-Cycle VIII were used in this study. In addition to carcass traits, LT was evaluated for mineral concentrations...

This paper presents an empirical analysis of significance of different process and product metrics in defect prediction models. 48 releases of 15 open-source and 38 releases of 7 proprietary projects were investigated. Pearson correlation coefficients with the number of defects were calculated for each of the metrics respectively. Subsequently defect prediction models were built using linear st...

We investigated the ability of the GDx-Nerve Fiber Analyzer (NFA) to discriminate between normal and early glaucomatous eyes among Korean individuals by reviewing the medical records of 217 consecutive subjects: 61 early glaucoma patients, 68 ocular hypertensive patients, and 88 normal subjects. GDx parameters were compared using ANOVA. The Receiver Operating Characteristics (ROC) curve for eac...

Purpose: The purpose of this study was to examine the relationship between pedometer-determined physical activity measured in steps per day and body composition variables in healthy, postmenopausal women. Methods: Height, weight, percent body fat, waist circumference and hip circumference were measured on ninety-three women (60.9 ± 5.76 years). Each subject wore a pedometer for 14 consecutive d...

This study was conducted to assess the correlation between growth response, phytoaccumulation factor of different tissues, and elemental composition in tomato seedlings exposed acid mine water (AMW). In pairwise determinations values plant height, stem diameter, seed germination indices (radicle length, final percentage (FGP), emergency rate index (ERI), vigour (VI), (G%) (GRI)) compositions (C...
