Study of Toxic Elements in River Water and Wetland Using Water Hyacinth ( as Pollution Monitor.

The concentration of toxic elements present in surface water of Sutlej River and Harike wetland besides , commonly known as water hyacinth, is estimated employing inductively coupled plasma mass spectrometry (ICP-MS). Toxic elements such as cadmium (Cd), chromium (Cr), copper (Cu), manganese (Mn), nickel (Ni), lead (Pb), uranium (U), and zinc (Zn) are identified in the river as well as in Harike wetland catchment. Accumulation of elements in different parts of the water hyacinth plant is observed with the roots exhibiting maximum affinity followed by stem and then leaves.

Gated metabolic positron emission tomography (GAPET) of the myocardium: 18F-FDG-PET to optimize recognition of myocardial hibernation.

The aim of this study was to test the feasibility of the direct measurement of global and regional metabolic wall thickening with 18F-FDG-gated positron emission tomography (PET) in patients with coronary artery disease (CAD). Based on non-invasive (ECG, echocardiography) and invasive [cineventriculography (CVG), coronary angiography] investigations, 12 patients with CAD underwent gated metabolic PET studies with 18F-FDG. Myocardial wall thickening and wall motion analysis from short-axis horizontal and vertical long-axis slices were studied.
