background: bladder cancer (bc) is the most common genitourinary cancer in iranians with an unclear etiopathogenesis. long stress induced non-coding transcript 5 is a member of the 12-member family of long non-coding rnas, which is abundantly expressed in higher proliferative cells, as well as the cell vulnerable to cellular stress in response to chemical carcinogens. as variations in long non-...

Diazepam, an antianxietic agent, antagonized the stress-induced analgesia (SIA) distinctively depending on the characteristics of the stress. Psychological (PSY, using communication box)-SIA was completely blocked by 1 or 2 mg/kg of diazepam in the tail pinch (TP) method, but not antagonized by 1 mg/kg of the drug in the tail flick test. Swimming-SIA was resistant to diazepam in both methods an...

BACKGROUND Takotsubo cardiomyopathy also known as transient balooning syndrome is an increasingly reported phenomenon characterized by acute reversible apical or midventricular dysfunction. This stress- induced cardiomyopathy mimics myocardial infarction, but without significant coronary artery disease, and rarely presents in perioperative period. METHODS AND RESULTS We report a case of postm...

A stress response is an evolutionary heritage of ability to anticipate, identify and effectively respond to danger. After millions of years of evolution, perception of variety of stressors mobilizes neurologic, neuroendocrine, endocrine, immunologic and metabolic systems to maintain an ability to survive and propagate gens (natural selection). Additionally, in humans these mechanisms involve co...

The Tyr-MIF-1 family of neuropeptides (Tyr-MIF-1’s) includes MIF-1, Tyr-MIF-1, Tyr-W-MIF-1 and Tyr-K-MIF-1. Nowadays it is certain that they can modulate pain and some forms of stress-induced analgesia (SIA) by antiopiate and μ-specific processes. The objectives of the present study were twofold: 1) to determine the involvement of opioid system in analgesia induced by immobilization, cold and h...

the aim of this study was to determine whether anesthesia consisting of sedation induced by intramuscular administration of xylazine-diazepam and lumbosacral analgesia induced by epidural administration of lidocaine and xylazine is satisfactory for castration and ovariohysterectomy in cats. six adult (3 male and 3 female, 2.5 ± 0.5 years of age) cats (mean body weight ± sd, 2.2 ± 0.44 kg) were ...

Experiments were carried out to determine whether stress induces biochemical changes in the pro-opiomelanocortin (POMC) system in anterior (AL) and intermediate-posterior lobe (IPL) of rat. In a series of pulse-chase experiments, acute stress led to an increase in POMC biosynthesis and shorter half-life in AL. However, when the animals were chronically stressed, the AL no longer exhibited incre...

BACKGROUND Chronic and inescapable trauma is implicated in the stress-induced analgesia (SIA) response. METHODS A sample of 27 chronically battered women was compared with 28 trauma-exposed nonbattered women on their SIA response at 1 month postindex assault. RESULTS For the battered women sample, the SIA response at 1 month postindex assault was found to significantly predict an increase i...

Stress is known to elicit pain relief, a phenomenon referred to as stress-induced analgesia. Based on stress parameters, opioid and non-opioid intrinsic pain inhibitory systems can be activated. In the present study, we assessed whether changing the duration of stress would affect the involvement of endogenous opioids in antinociception elicited by swim in warm water (32 °C), known to be opioid...
