The non-cancer adverse health effects of formaldehyde are largely a manifestation of its ability to irritate mucous membranes. As a result of its solubility in water and high reactivity, formaldehyde is efficiently absorbed into the mucus layers protecting the eyes and respiratory tract where it rapidly reacts, leading primarily to localized irritation. Acute high exposure may lead to eye, nose...

AIM The aim of this study was to evaluate the diagnostic utility of natriuretic peptides of type A and B as noninvasive markers in the diagnosis and treatment of congenital and valvular heart disease. METHODS Blood samples from 82 patients with various congenital and valvular heart diseases were measured for A and B natriuretic peptide levels and levels compared with those in a reference grou...

1. Summary Acute, 8-hour and chronic reference exposure levels (RELs) were derived for inorganic arsenic including arsine. Inorganic arsenic causes a wide variety of toxic effects in humans and experimental animals including effects on development, the vascular system, the nervous system, blood, lung, and skin. The most sensitive acute effects were seen in mice (fetal development) whereas the m...

conclusions these findings show non-adherence to the stard. the authors, reviewers, and editors should pay more attention to reporting by checking stard statement items and including a flow diagram to represent study design and patient flow. objectives up to date, few data exist about the quality of diagnostic accuracy studies in iran. therefore, we evaluated the extent of adherence to the star...

there are significant challenges associated with qualitative and quantitative nucleic acid tests performed in diagnostic laboratories. the development of internationally available certified reference materials which can be traced to reference measurements will contribute to a better understanding of the performance characteristics of nucleic acid tests and enhance reliability and comparability ...

background: in the era of well-developed site-specific treatment strategies in cancer, identification of occult primary is of paramount importance in cup patients. furthermore, exact determination of the extent of the disease may help in optimizing treatment planning. the aim of the present study was to investigate additional value of f-18 fdg pet/ct in patients with cancer of unknown primary (...
