according to global statistics, over 80,000 deaths occur by suicide annually. up to 90% of complete suicides are based on psychiatric disorders specifically major depressive disorder (mdd) and bipolar disorder. furthermore high levels of inflammation have been indicated in suicidal patients in both central nervous system and the peripheral blood. two biological mechanisms that play a key role i...

background: the phosphatidylinositol 3-kinase/akt signaling pathway is recognized as a key driver of cancer cell survival and proliferation, and is often contingent upon an impairment of expression/function of the pten tumor suppressor, a negative regulator of this pathway. in addition, the cytoskeletal signaling protein tensin 2 has also been implicated as a negative regulator of this pathway....

Objective(s): The link between a hyperglycemic intrauterine environment and the development of diabetes later in life has been observed in offspring exposed to gestational diabetes mellitus (GDM), but the underlying mechanisms for this phenomenon are still not clear. Reduced β-cells mass is a determinant in the development of diabetes (type 1 and type 2 diabetes). Some recent studies have provi...

chronic myeloid leukemia (cml) is a myeloproliferative disease of the hematopoietic stem cells, characterized by the presence of the philadelphia (ph) chromosome. although imatinib inhibits the bcr-abl kinase activity, clinical experiences confirm that imatinib may not target cml stem cells in vivo. the identification of signaling pathways responsible for the self-renewal properties of leukemic...

colorectal cancer (crc) is the second leading cause of cancer death. progress has been made in the development of chemotherapy for advanced crc. targeted therapies against vegf or egfr are now commonly used. however, many cases show that tolerance develops to such treatments; therefore, new strategies are required to replace or complement current therapies. nuclear factor-?b (nf-?b) transcripti...

introduction: the ablation technique is one of the important therapeutic interventions for treatment of av nodal tachyarrhythmia. different animal models have been developed to study the effects of ablation on the functional interanodal structure. the aim of the present study was to develop a new model of computer analysis to produce lesions by using direct voltage in isolated perfused rabbit 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...
