background: repeated applications of animal manure as fertilizer are normal agricultural practices in malaysia that may release veterinary antibiotics to environment from treated animals. methods: environmental risk assessment (era) on 5 commonly used antibiotics and one hormone in malaysian broiler farm was calculated using the ratio of measured environmental concentration (mec) and predicted ...

background: new technologies using hazardous materials usually have certain risks. it is more serious when the technology is supposed to be applied in a large scale and become widely used by many people. the objective of this paper was to evaluate the risk of vapor cloud explosion in a hydrogen production process. methods: potential hazards were identified using the conventional hazard identifi...

accounts for 27% of all cancers. according to the national cancer institutes' reports, the risk of breast cancer among american women is 13%. the current study aims to evaluate the level of risk perception of breast cancer and to identify its related factors amongst female employees. methods: this project was a cross-sectional study and participants were female employees working in hospitals an...

results a total number of 43 specimens were studied, from which 9 were obtained from patients with metastatic prostate cancer. the expression of five examined genes had no correlation with psa level and gleason score. the expression of amacr decreased in metastatic prostate cancer (p = 0.02). the expression of other genes showed no difference between metastatic and non-metastatic tumors (p > 0....

and dormant cancer cell, [ 12 ] are often rare in a mixture of heterogeneous cells (usually less than 1% of the total cell number). The low number of target cells in blood sample largely limits the detection capability and reduces effectiveness of the time-sensitive cancer treatment. Therefore, the isolation and detection of the rare cells for early diagnosis and prognosis of cancers have drawn...

background: recently, the development of new biomarkers as prognostic and predictive markers in prostate cancer has been crucial. objectives: this study was aimed to determine whether serum vascular endothelial growth factor (vegf) levels would be a prognostic marker or risk assessment factor in patients with prostate cancer and to investigate whether it could differentiate cancerous tissue fro...

background: in the refractory brick manufacturing industry, because of the high risks associated with the level of dust in the factory environment and thermal stress, a precise identification of industrial hazards is required as a part of safety analysis. the aim of this study was to introduce a preventive approach to risk identification and assessment in the refractory brick production line.  ...
