Multielement analysis in serum of thyroid cancer patients before and after a surgical operation

Biological Trace Element Research

Abstract

Concentrations of trace elements Zn, Cu, Fe, Mn, Mg, and Sr in the serum of 50 thyroid cancer patients and 50 healthy controls were analyzed comprehensively by Pattern Recognition Analysis Method. Based on the Principal Component Analysis Method, Zn, Cu, and Sr were found to be the principal elements with significant variations between patients and healthy controls. According to the Mahalanolis Distance Decision and Nonlinear Mapping Methods, the trace elements levels in the serum of cancerous patients were found significantly different from that of controls. For 16 thyroid malignant tumor patients who underwent surgery, sample points of patients after surgery were directional away from corresponding points before surgery. However, an overlapping was found and separation between two groups of points was not complete. This finding suggests that there may be a latency period for the restoration of trace element levels after removal of the malignant tumorous tissue.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.

Signaling in Adult Neurogenesis

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
