PURPOSE Dexamethasone (Dex), a glucocorticoid (GC), is used as a pretreatment drug in cancer patients undergoing chemotherapy. Dex functions by binding to the glucocorticoid receptor (GR) to prevent allergic reactions and severe chemotherapeutic side effects such as nausea and vomiting. However, the mechanisms by which Dex causes chemoresistance remain unknown. METHODS We used docetaxel and c...

   Our previous study showed that Coriandrum sativum (CS) has antinociceptive effects, but the mechanisms that mediate this effect are not clear. The present study was designed to test the role of opiate system in the antinociceptive effects of CS on acute and chronic pain in mice using Hot Plate (HP), Tail Flick (TF) and Formalin (FT) tests and also to compare its effect with dexamethasone (DE...

CONTEXT Dexamethasone (DEX) is used to prevent virilization in female fetuses at risk of congenital adrenal hyperplasia (CAH). Given that treatment has to be started before the genotype is known, 7 out of 8 fetuses will be exposed to DEX without benefit. OBJECTIVE To evaluate long-term cognitive effects of prenatal DEX therapy in healthy (non-CAH) DEX-treated children. DESIGN AND SETTING Ob...

BACKGROUND Dexmedetomidine (Dex) provides sedation and analgesia by acting on central alpha-2 receptors and is suitable for use after extubation because it has little respiratory depression. Considering the sympathoinhibitory and anxiolytic action of Dex, there is the possibility that Dex might reduce the incidence of atrial fibrillation (AF), which is recognized as a common complication after ...

PURPOSE To identify myocilin (TIGR/MYOC) properties that are specific to the human trabecular meshwork (HTM). To search for genes highly expressed in dexamethasone (DEX)-induced HTM cells that are barely expressed or absent in DEX-induced cells from other tissues. METHODS TIGR/MYOC induction by DEX (10(-7) M for 8-10 days) was analyzed by Northern and Western blot analyses in HTM, human umbil...

Previous studies indicated that stress and glucocorticoids have modulatory effects on acute pain. The aim of present study was to determine the interaction between stress and glucocorticoids with activation of voltage dependent Ca2+ channel on modulation of acute pain in mice. Male albino mice (25-30 g) were used for this experiment. Tail flick and hot plate were used for evaluation of analgesi...

PURPOSE The efficacy of low-dose thalidomide (THAL) plus dexamethasone (DEX) has been evaluated in myeloma. The clinical outcome of patients treated with THAL-DEX was compared with that of a control group treated with conventional chemotherapy (CC). EXPERIMENTAL DESIGN A total of 120 relapsed/refractory patients to one (52%), or two or more(48%) lines of chemotherapy were treated with THAL 10...

OBJECTIVE The purpose of our study was to observe the influence of dexmedetomidine on complications caused by hemabate in patients undergoing caesarean section. METHODS A total of 120 females (age range, 20-40 years) at 35-40 weeks gestation who delivered by cesarean between September, 2014 and December, 2014 were enrolled in our study. Patients were randomly allocated into three groups that ...

SOX9 is a transcription factor that activates type II procollagen (Col2a1) gene expression during chondrocyte differentiation. Glucocorticoids are also known to promote chondrocyte differentiation via unknown molecular mechanisms. We therefore investigated the effects of a synthetic glucocorticoid, dexamethasone (DEX), on Sox9 gene expression in chondrocytes prepared from rib cartilage of newbo...
