Mammary cancer, which is the second most common cause of cancer deaths, is one of the problems of global public health. It is argued that anti estrogenic agents such as melatonin will lead to a new aspect in treatment of breast cancer. In addition, zinc, which plays a crucial role in the etiology of cancer, is vital for many cellular processes, and an important trace mineral. Trace elements are regarded as multiple anti-cancer agents that regulate various biological mechanisms. METHODS: In this study, it was aimed to investigate the effects of melatonin and zinc application on lipid peroxidati ...Daha fazlası

Metabolic dysfunction is a critical step in the etiopathogenesis of Alzheimer's disease. In this progressive neurological disorder, impaired zinc homeostasis has a key role that needs to be clarified. The aim of this study was to investigate the effect of zinc deficiency and administration on hippocampal Nogo-A receptor and osteocalcin gene expression in rats injected with intracerebroventricular streptozotocin (icv-STZ). Forty male Wistar rats were divided into 5 groups in equal numbers: Sham 1 group received icv artificial cerebrospinal fluid (aCSF); Sham 2 group received icv a CSF and i.p. ...Daha fazlası
