background: multiple sclerosis (ms) is a t cell mediated autoimmune disease with unknown etiology. appropriate ms therapeutic strategies need thorough understanding of both disease etiology and pathogenesis mechanisms. ligation of tlr-2 and tlr-4 stimulates the production of several cytokines leading to cns autoimmunity and neurodegenerative diseases. objective: to find a relationship between m...

objectives the aim of this study was to examine the effects of interleukin 2 receptor blockers on patient and graft survival in renal-transplanted children. patients and methods one hundred and eighty six children aged 7-13 years who received renal transplantation in university-affiliated hospital between 2003 and 2012 were enrolled in the study. all patients received prednisolone, cyclosporine...

background: the peroxisome proliferator-activated receptor-γ (ppar-γ) is a nuclear hormone receptor. it is predominantly expressed in adipose tissue and as a receptor for thiazolidinediones, it has drawn attentions towards itself as a key molecule to trigger pathways involving in some diseases such as cancers, type 2 diabetes, inflammations and osteoporosis. a proline changed to alanine in codo...

Objectives: MRI is the most sensitive modality for local staging of breast cancer. Herceptin receptor over-expression seen in 15% - 30% tumours, and associated with increased aggression, poorer prognosis, higher grade at diagnosis lymphatic dissemination. This study aimed evaluating role positive vs negative tumours. Methods: 193 pre-operative MRIs were performed 2021 162 Her-2 37 Recall rates ...

Dear Editor-in-ChiefMalignant melanoma is a tumor arising from melanocyte; this tumor rarely occurs before puberty, with higher mortality rate in males and better survival rate in female patients affected by metastatic melanoma (1, 2). These facts propose that a relationship and association may exist between estrogens and melanoma. The effects of estrogens are mediated by...

Multiple sclerosis is an autoimmune disease of the central nervous system which its main characteristic is an inflammation and demyelination and subsequent, neural degeneration. Many studies have shown that inflammation causing neuronal demyelination. MS is the most common cause of chronic neurological disability in during youth which the prognosis is that can be death. Platelet activating fact...

Background and Objective: Methylphenidate (MPH), as a central nervous system stimulant, is often used to manage hyperactive disorders. The literature is scarce regarding the behavioral consequences of chronic MPH treatment and the role of involved receptors. Thus, in the current study involved receptors in MPH induced-anxiety, depression and motor activity disorders were evaluated. Materials a...

Long-term potentiation (LTP) is a process that certain types of synaptic stimulation lead to a long-lasting enhancement in the strength of synaptic transmission. Studies in recent years indicate the importance of molecular pathways in the development of memory and learning. Tropomyosin receptor kinase B (TrkB) is a member of the neurotrophin receptor tyrosine kinase family, that its ligand is b...
