Impact of aging on perceptual asymmetries for horizontal and vertical stimuli in the greyscales task.

Through the paper version of the grayscale task, this study examines the impact of aging and gender on horizontal and vertical pseudoneglect in healthy right-handed Japanese people. Participants included 168 (84 women and 84 men) healthy right-handed participants between the ages of 18 and 85, which were divided into three age cohorts (i.e.

[Right-versus Left-handedness in Behavioral and Cognitive Neuroscience].

Globally, approximately 90% of individuals are right-handed, while the remaining 10% are left-handed. Handedness is associated with functional lateralization of cerebral dominance, and may also be associated with various types of psychological characteristics. Unfortunately, neuromyths of left handedness have become deeply embedded in public consciousness due to misleading studies.

Effects of immediate recall trial on one-year delayed recall performance in Rey complex figure test.

This study aimed to examine the effects of the presence or absence of an immediate recall trial on university students' (n = 39) performance on the one-year delayed recall test in the Rey complex figure test (RCFT). Participants were divided into two groups that took either one or two tests, respectively. In the first year, the participants in the two-test condition completed a copy trial and an immediate recall trial, whereas those in the one-test condition underwent the copy trial only.

Effects of the immediate recall trial on Delayed Recall performance in the Rey Complex Figure Test in young and older adults.

This study determines whether the presence or absence of the Immediate Recall trial influences performance among healthy young and older adults on the 30-min Delayed Recall task of the Rey Complex Figure Test. Participants in the 1-test condition (24 young adults and 24 older adults) underwent the Copy trial and 30-min Delayed Recall trial only, while participants in the 2-test condition (24 young adults and 24 older adults) completed the Copy trial, the Immediate Recall trial, and the 30-min Delayed Recall trial. Both older and younger participants in the 2-test condition showed significantly higher scores than those in the 1-test condition on the 30-min Delayed Recall trial.

Self-rated right-left confusability and performance on the Money Road-Map Test.

This study assessed the relationship between self-rated right-left confusability and performance on the Money Road-Map Test (MRMT). Eighty-six undergraduate university students (44 women and 42 men) rated right-left subjective confusability using a questionnaire, and then completed the MRMT. Low- and high-confusability groups were determined using self-rated confusability scores.

Medical College of Georgia Complex figures in repeated memory testing: a preliminary study of healthy young adults.

The Medical College of Georgia Complex Figures developed as an alternate version of the Rey-Osterrieth Complex Figure for repeated assessments. The aim of this study was to examine whether serial assessment with different figures of the Medical College of Georgia Complex Figures could attenuate the practice effects. 64 volunteers (M age = 20.

Right- and left-hand performance on the Rey-Osterrieth Complex Figure: A preliminary study in non-clinical sample of right handed people.

Intermanual differences in performing the Rey-Osterrieth Complex Figure Test (ROCFT) were experimentally investigated. Undergraduate participants (n = 120; 60 men, 60 women) were randomly assigned to one of four groups based on the hand used in a copy trial and a recall test. Hand use had a minimal effect on performance in the copy trial.

One-year delayed recall performance of the Rey-Osterrieth Complex Figure in a healthy young adult sample.

This study investigated the performance of the very long-term delayed recall trial (1 year) of the Rey-Osterrieth Complex Figure Test (ROCF) in a healthy young adult sample. Forty-one healthy university students were given the delayed recall trial, one year after receiving the copy and the 3-minutes delayed recall trial of the ROCF. Although a significant decrease of the recall score was shown by comparison with the 3-minutes delayed recall trial, all the participants were able to draw a certain figure including the main features of the ROCF on the 1-year delayed recall trial.

Comparison of the Medical College of Georgia Complex Figures and the Rey-Osterrieth Complex Figure tests in a normal sample of Japanese university students.

Comparability of copy and recall performance on the four figures of the Medical College of Georgia Complex Figures and the Rey-Osterrieth Complex Figure were examined using an incidental learning paradigm with 60 men and 60 women, healthy volunteers between the ages of 18 and 24 years (M = 21.5 yr., SD = 1.

Comparability of the Rey-Osterrieth Complex Figure, the Taylor Complex Figure, and the Modified Taylor Complex Figure in a normal sample of Japanese speakers.

The comparability of recall performance was examined on the Rey-Osterrieth Complex Figure, the Taylor Complex Figure, and the Modified Taylor Complex Figure as measures of visuospatial abilities and visual memory in 66 healthy Japanese university students. A between-subjects design was used in which each of the participants received the three figures. The interrater reliability of each was excellent.

Glutathione S-transferase GSTM1, GSTT1 and p53 codon 72 polymorphisms in human tumor cells.

The genes of the glutathione S-transferase (GST) family encode enzymes that appear to be critical in cellular protection against the cytotoxic effects, whereas p53 is a tumor suppressor gene. Despite a large number of studies on germline polymorphisms of GSTM1, GSTT1 and p53 genes, there have been very few reports on genotyping of these genes in human malignant tumor cells. In this study, we investigated GSTM1, GSTT1 and p53 codon 72 polymorphisms in a variety of human tumor cell lines originating from different organs to clarify tissue-specific polymorphic frequency of these genes in human solid tumors.

Influence of severe endometriosis on gene expression of vascular endothelial growth factor and interleukin-6 in granulosa cells from patients undergoing controlled ovarian hyperstimulation for in vitro fertilization-embryo transfer.

Objective: To evaluate how endometriosis affects expression of vascular endothelial growth factor (VEGF) and interleukin-6 (IL-6) in granulosa cells.

Design: Prospective study.

Setting: IVF-ET program at Osaka Medical College.
