Associations of trace element levels in paired serum, whole blood, and tissue: an example of esophageal squamous cell carcinoma.

Previous studies have extensively explored impacts of trace elements on human beings and complex relationships with cancers. However, contradictory conclusions may be more challenging to explain due to biological specimen differences. To investigate the distribution of trace elements inside body, we collected serum, whole blood and tissues from 77 patients with esophageal squamous cell carcinoma (ESCC), as well as serum and whole blood from 100 healthy individuals, and determined the concentrations of 13 elements (Al, V, Cr, Mn, Co, Ni, Cu, Zn, As, Se, Sr, Cd, and Pb) with inductively coupled plasma-mass spectrometry (ICP-MS).

Association between Serum Level of Multiple Trace Elements and Esophageal Squamous Cell Carcinoma Risk: A Case-Control Study in China.

We investigated the associations between multiple serum trace element levels and risk for esophageal squamous cell carcinoma (ESCC). A total of 185 ESCC patients and 191 healthy individuals were recruited in our study. The concentration of 13 trace elements (Al, V, Cr, Mn, Co, Ni, Cu, Zn, As, Se, Sr, Cd and Pb) in serum was determined with inductively coupled plasma mass spectrometry (ICP-MS).

Diagnosis and prognosis evaluation of 1,2-dichloroethane encephalopathy--magnetic resonance imaging combined with diffusion tensor imaging and magnetic resonance spectroscopy study.

Neuroimaging findings in 1,2-dichloroethane (1,2-DCE) encephalopathy have seldom been reported. We present the comprehensive neuroimaging findings, conventional magnetic resonance imaging (MRI) combined with diffusion tensor imaging (DTI) and 1 H-magnetic resonance spectroscopy ( 1 H-MRS), in a case of 1,2-DCE encephalopathy. On day-4 the signal intensity of the lesions on diffusion-weighted imaging (DWI) was higher than that with T2-weighted imaging (T2WI); mean apparent diffusion coefficient (ADC) values for lesions were lower than control values.
