objective: in this study, we investigated the combined effect of 2-methoxyestradiol (2me2) and 60co on the cytogenetic damage of iododeoxyuridine (iudr) in the spheroid model of u87mg glioblastoma cancer cell lines by alkaline comet assay. materials and methods: u87mg cells were cultured as spheroids with diameters of 350 μm. as control, the spheroids of one plate were not treated. other cultur...

OBJECTIVES Previous studies revealed an unclear correlation between the growth rate of renal cell carcinoma (RCC) and tumor grade and did not focus on certain histological subtype. This report investigated the correlation between the growth rate and tumor grade in clear cell RCC (ccRCC). METHODS We reviewed 60 patients with 61 ccRCC confirmed by delayed surgeries after at least 12 months of a...

This study examined the clinical findings of visual display terminal (VDT) users who presented with monocular symptoms. The sample consisted of 35 people performing sustained work at VDTs. Each subject underwent an evaluation that included: visual acuities, determination of refractive status, ocular motor testing, the stability of fixation, degree of suppressions of simultaneous binocular perce...

In spite of the clarification of some significant physiological factors of visual fatigue caused by VDT work, pupillary reflexes have not been studied as to how they are affected after prolonged visual work. This study examined visual function changes objectively in terms of pupillary reflexes and lens accommodative responses after a 4-hr VDT operation task. The relationship between the two fun...

BACKGROUND This study is a part of the interdisciplinary project The Office Illness Project in Northern Sweden, which was initiated with a questionnaire study in late 1988. Previously published results from the project have shown that facial skin symptoms reported among visual display terminal (VDT) workers are associated with a number of exogenous factors. This part of the project investigated...

OBJECTIVES This study was to determine the prevalence and work-related risk factors of neck-upper extremity musculoskeletal disorders (MSDs) among video display terminal (VDT) users. METHODS A comparative cross-sectional study was conducted; there were 60 VDT users and 35 controls. The participants filled in a structured questionnaire, had electrophysiological tests and an X-ray of the neck. ...

UNLABELLED This study investigated the effectiveness of a workstation ergonomic intervention for work-related posture and low back pain (LBP) in Video Display Terminal (VDT) workers. 100 VDT workers were selected to receive the ergonomic intervention, whereas 100 were assigned to a control group. The two groups were then crossed-over after 30 months from baseline. Follow-ups were repeated at 5,...

The aim of the present study was to test the structural stability and reliability of the Swedish occupational fatigue inventory (SOFI) for use in a group of Chinese visual display terminal (VDT) workers. A qualified translator was recruited to translate the Chinese version of the SOFI (SOFI-C). The content validity was established with 12 bilingual practitioners and seven professional experts. ...

In this paper, participants operated visual display terminals (VDT); the authors analyzed their pulse wave signals to develop objective indices for diagnosing and assessing VDT-induced. The experiment used 30 healthy undergraduates test subjects; each subject operated static PC for 4 hours. The pulse waves of local blood volumes in the test subjects' finger-tips were measured every 30 minutes f...
