Several trace elements are essential micronutrients and are required for various body functions and well being of the immune system. The deficiencies of trace elements and infectious diseases often coexist and exhibit complex interactions. Several trace elements such as selenium, zinc, copper, manganese, etc. have immunomodulatory functions and thus influence the susceptibility to the course an...
Background: Accumulation or deficiency of trace elements can occur in hemodialysis patients and it increases risk of cardiovascular or other organs disorders. Special ions levels such as sodium and bicarbonate in dialysis fluid are accurately regulated but the remaining elements are not regularly measured. Aluminum and lead belong to the biologic performance free heavy metals .They also has a t...
Parkinson’s Disease (PD) is a chronic, progressive, neurodegenerative disorder with motor and non-motor signs and symptoms. PD is caused by idiopathic degeneration of dopamine-producing cells in the substantia nigra, located in the midbrain. Recently, Trace elements have been recognized to play an important role in the development of Parkinson’s disease (PD). The aim of this review ...
Background: Asthma is a multifactorial disease and its severity varies with the inflammatory grade. There are conflicting reports about the roles of trace elements in asthma. This study examined the effects of zinc (Zn), copper (Cu), and selenium (Se) concentrations in sera of patients with allergic asthma attending Ghaem Hospital, Mashhad, Iran. Methods: Forty-nine patients, aged 10 to 50 y...
Hemodialysis is being implicated in the development of metabolic disturbances, as complications have been observed and the role of trace metals in their development has been questioned. In 78 renal failure patients who underwent hemodialysis, serum levels of zinc and copper were determined before and after first hemodialysis. Acute and chronic renal failure patients were found to have lowe...
The geochemical characteristics of sediments deposited within a channel-type reservoir situated behind the weir of a water mill on the River Liswarta (southern Poland) were studied in relation to land use in the catchment. The catchment in question is an agricultural one with large forest areas. The contamination of sediments with trace elements was assessed using the geoaccumulation index. The...
