a group of 1,3-biarylhydrazide derivatives possessing a cox-2 azido pharmacophore at the para- position of the c-1 phenyl ring in conjunction with a n-3 phenyl or substituted-phenyl ring (4-f,4-cl,4-ome) were designed and synthesized based on nucleophilic substitution reaction. a molecular modelling study of these compounds showed that the designed molecules were well bound with the active site...

objective: hypoglycemia with multiple etiologies is a common in diabetic patients. the current study describes the probability of interaction between maprotiline, selective serotonine reuptake inhibitors like citalopram for induction of hypoglycemia. case presentation: a 47 year-old diabetic woman used tablet citalopram 20mg daily because of generalized anxiety disorder from two years ago, but ...

A gene network gives the knowledge of the regulatory relationships among the genes. Each gene has its activators and inhibitors that regulate its expression positively and negatively respectively. Genes themselves are believed to act as activators and inhibitors of other genes. They can even activate one set of genes and inhibit another set. Identifying gene networks is one of the most crucial ...

backround laryngopharyngeal reflux (lpr) is the backflow of stomach contents above upper esophageal sphincter, into the pharynx, larynx, and upper aerodigestive system. objectives in this study, effects of omeprazole over voice quality in muscle tension dysphonia with laryngopharyngeal reflux was ınvestigated. patients and methods nine patients, 7 males and 2 females, aged between 27-43 (mean a...

To identify dysregulated pathways in distinct phases of NOTCH1-mediated T-cell leukemogenesis, as well as small-molecule inhibitors that could synergize with or substitute for gamma-secretase inhibitors (GSIs) in T-cell acute lymphoblastic leukemia (T-ALL) therapy, we compared gene expression profiles in a Notch1-induced mouse model of T-ALL with those in human T-ALL. The overall patterns of NO...

background: recently, it has been revealed that tyrosine kinase inhibitors (tkis) act through inducing both oxidative and endoplasmic reticulum (er) stress in chronic myeloid leukemia cells. however, er stress signaling triggers both apoptotic and survival processes within cells. nevertheless, mechanisms by which tkis avoid the pro-survival effects are not clear. the aim of this study was to ev...

Over the past decade, several kinase inhibitors have been approved based on their clinical benefit in cancer patients. Unfortunately, in many cases, patients develop resistance to these agents via secondary mutations and alternative mechanisms. To date, several major mechanisms of acquired resistance, such as secondary mutation of the epidermal growth factor receptor (EGFR) gene, amplification ...

Oxidative stress is believed to be an important mediator of neurodegeneration. However, the transcriptional pathways induced in neurons by oxidative stress that activate protective gene responses have yet to be fully delineated. We report that the transcription factor Sp1 is acetylated in response to oxidative stress in neurons. Histone deacetylase (HDAC) inhibitors augment Sp1 acetylation, Sp1...
