Brain-Derived Neurotrophic Factor (BDNF) is a neuroprotectant candidate for neurodegenerative diseases. However, there are several clinical concerns about its therapeutic applications. In the current study, we selected BDNF-mimicking small peptides from phage-displayed peptide library as alternative molecules to the clinical challenges. The peptide library was screened against BDNF receptor (Ne...

Purpose: This study aimed to evaluate the relationship between strain elastography and immunohistochemical markers, histologic grade, molecular subtyping in invasive breast cancer.
 Materials Methods: The relationships index values progesterone receptor, estrogen human epidermal growth factor receptor 2, Ki-67, subtype 171 patients who had not received neoadjuvant treatment underwent breas...

Background & Objective: Breast cancer has a pivotal role in many deaths caused by malignancies. Epidermal growth factor receptor-2 (EGFR-2 or HER-2) and estrogen receptor (ER) have immense predictive values as prognostic factors. cancers that steroid receptors respond to hormone therapy show better prognosis than without receptors.Materials Methods: A retrospective cross-sectional study was per...

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...

g -aminobutiric acid (gaba), the major inhibitory neurotransmitter in the central nervous system has two major receptor subtypes (gabaa and gabab). gabab receptors are activated by the antispastic and muscle relaxant agent, baclofen, which is a lipophilic derivative of gaba. since 1962 several strategies have been reported for the synthesis of baclofen.in this study an approach has been made to...

In recent years, the potential of marine natural products as anticancer agents, specifically for breast cancer, has been examined. The sea cucumber (Holothuroidea: Echinodermata) is known to contain triterpene glycosides, which have shown anticancer or cytotoxic activity. In this research, molecular docking of selected sea cucumber bioactive compounds was conducted on five receptor targets that...

context triple negative breast cancer (tnbc) is a heterogeneous group of diseases that is negative for esterogen receptor (er) progesteron receptor (pr) and human epidermal growth factor receptor 2 (her2). this type of breast cancer is typically high-grade carcinomas, although low-grade tumors occur. the aim of this review is to focus on molecular classification and features, prognostic markers...

The present study describes the changes in expression of hydroxy- carboxylic acid receptor 2 (HCA2 receptor) in femoral epiphysis and metaphysis of rats with glucocorticoid-induced osteoporosis (GIO). 16 growing male Sprauge dawley rats were randomly divided into two equal groups consisting of normal control and rats that were rendered osteoporotic by receiving 0.1 mg/kg/day dexamethasone throu...

introduction: 5-ht1a receptor is related with a variety of neuropsychiatric disorders. . in this study a phenolic analogue derived from dway [desmethyl way-100635 (n-(2-(1-(4-(2-methoxyphenyl)piperazinyl)-ethyl))-n-(2-pyridinyl) cyclohexanecarboxamide)] is used to design the desired structure of 5-ht1a receptor imaging agents after labeling with [99mtc (co) 3(h2o) 3] + core via dithiocarbamate ...

Introduction: It is known that acute and chronic stress induce hormonal and neuronal changes which affecting both pain threshold and nociceptive behaviours. Orexin plays an important role in modulation of pain and stress. Considering pain modulation during stress and the role of orexin in pain and stress, orexin might be involved in pain modulation during stress.We evaluated the involvement ...
