introduction: fennel is rich in phytoestrogens and is used for estrogen deficiency disorders. estrogens affect anxiety through neurochemical systems such as gaba-a receptors. in this study the effects of fennel on gaba-a and estrogen receptors in anxiety were investigated. methods: adult female wistar rats weighing (180±20 g) were divided into 8 groups. groups received saline, fennel (200, 500,...

Long-term potentiation (LTP) is a biological process of learning and memory after a high-frequency train of electrical stimulations. By binding of brain-derived neurotrophic factor (BDNF) to Tropomyosin receptor kinase B (TrKB) receptors in postsynaptic neurons, tyrosine kinase Fyn is bound to these receptors and hereby plays a mediating role to binding and activation of N-methyl-D-aspartic aci...

introduction: chemokine receptors are found on the surface of stem cells. there have been 19 distinct chemokine receptors described in mammals. chemokines are major players in migration and homing. therefore, changes in their levels or function can help us to increase the migratory potential of these cells. valproic acid differs in structure from other drugs in common use. the way in which valp...

introduction: 17&beta-estradiol; modulates nociception by binding to the estrogenic receptors and also by allosteric interaction with other membrane-bound receptors like glutamate and gabaa receptors. in addition to its autonomic functions, paragigantocellularis lateralis (lpgi) is involved in the pain modulation, too. the aim of the current study was to investigate the involvement of the membr...

Background: Boesenbergia pandurata or fingerroot is known to have various pharmacological activities, including anticancer properties. Extracts from these plants are inhibit the growth of cancer cells, breast cancer. Anti-breast activity significantly influenced by inhibition two receptors: ER-α and HER2. However, it unknown which metabolites B. play most crucial role in exerting activity. Obje...

ABSTRACT Humans sense taste and smell of various chemical substances through approximately 430 chemosensory receptors. The overall picture ligand–chemosensory receptor interactions has been partially clarified because numerous interactions. This study presents a new method that enables rapid simple screening It would be useful for identifying receptors activated by odor substances.

signaling amp-activated protein kinase (ampk), an energy sensing enzyme, has been implicated in controlling inflammation. in this study we investigated whether activation of ampk by metformin could protect the lung from lipopolysaccharide (lps)-induced acute injury by inhibitingng tlr4 pathway. male wistar rats were randomly divided into 3 groups (n=6): control group received normal saline (0.5...

Background: Frizzled receptors (FZD) play a pivotal role in the initiation and progression of a wide array of cancers. Dysregulated expression of FZD receptors is correlated with higher metastasis and invasive potential, as well as short survival in many malignancies. In this meta-analysis, we aimed to verify the prognostic value of FZD receptor expression on patients’ survival with different t...
