introduction: breast cancer is the most common cancer in women worldwide and her-2 is one importantly prognostic factor in this cancer. tumor markers use as a criterion for predicting recurrence, but in breast cancer physical examination and mammography are important factors that are recommended for following up the recurrence. the aim of this study was to assess the correlation between breast ...

The let-23 gene, which encodes a putative tyrosine kinase of the epidermal growth factor (EGF) receptor subfamily, has multiple functions during Caenorhabditis elegans development. We show that let-23 function is required for vulval precursor cells (VPCs) to respond to the signal that induces vulval differentiation: a complete loss of let-23 function results in no induction. However, some let-2...

introduction: elective upper and lower gi endoscopy is usually performed in children on an outpatient basis with the child under sedation or general anesthesia (ga). the objective of this study was to describe anesthesia related complications in   children undergoing elective gi endoscopy.   materials and methods: the study design was descriptive on 1388 patients undergoing elective gi endoscop...

Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system (CNS). In MS, myeloid dendritic cells (mDCs) secrete elevated amounts of IL-23, a potent proinflammatory cytokine, compared to healthy donors. Here, we examined the role of CD46, a complement binding factor, in mDCs by analyzing cytokine and chemokine production in healthy donors and patients with MS. There ...

Angiotensin (Ang) II induces vascular injury in part by activating innate and adaptive immunity; however, the mechanisms are unclear. We investigated the role of interferon (IFN)-γ and interleukin (IL)-23 signaling. We infused Ang II into IFN-γ receptor (IFN-γR) knockout mice and wild-type controls, as well as into mice treated with neutralizing antibodies against IL-23 receptor and IL-17A. Ang...

Abstract Fibroblast growth factor 23 (FGF-23) hormone is produced by bone-embedded osteocytes and regulates phosphate homeostasis in kidneys. We found that administration of granulocyte colony-stimulating (G-CSF) to mice induced a rapid, substantial increase FGF-23 messenger RNA bone marrow (BM) cells. This originated mainly from CD45−Ter119+CD71+ erythroblasts. protein BM extracellular fluid w...

Background: Follicle stimulating hormone (FSH) receptor plays an important role in FSH signaling during reproductive development. Any changes in FSHR gene is resulted in alteration of amino acid in protein chain, consequence to affect the binding affinity, intracellular signaling and expression levels of FSHR. FSHR polymorphisms can be involved in etiology of many reproductive disorders such as...

male breast cancer is a rare disease with an increasing trend. due to limited information especially about the genetic basis of the disease in iran and the lower age of its onset, the disease requires more attention. the aim of this study was to screen the male patients with breast cancer for brca mutations as well as tissue markers of estrogen receptor (er), progesterone receptor (pr), human e...
