The purpose of the present study was to evaluate anti-nociceptive effects of morphine, tramadol, meloxicam and their combinations in rats. Seventy male Wistar rats were divided into seven equal groups and randomly assigned to receive intraperitoneal saline (S) (control group, 1.0 mL kg-1), morphine (MO) (4.0 mg kg-1), tramadol (TR) (12.5 mg kg-1), meloxicam (ML)...

Various investigations have shown (1) that lunar regoliths are extremely complex materials, (2) that ilmenite is a minor component (8 to 10%) of highTi regoliths, and (3) that most of the ilmenite is interlocked with other minerals or glass in regolith particles. A review of polished sections of Apollo regolith samples that I studied in 1970 in general confirms these findings. Beneficiation of ...

AIMS Respiratory changes in tricuspid regurgitation (TR) systolic velocities are occasionally demonstrated by Doppler echocardiography in patients with TR. We tested the hypothesis that excessive respiratory changes in TR velocities are diagnostic of severe TR. METHODS AND RESULTS The difference between the maximal (expiratory) and minimal (inspiratory) TR systolic velocities during spontaneo...

Some biological characteristics of broodstock and juvenile kutum, Rutilus kutum. were investigated using data collected from the estuaries of Tajen and Shirood Rivers (TR and SR) (southern Caspian Sea basin) as well as from the Caspian Sea in 2012. The results showed higher condition factors (CF) in the male broodstocks kutum than those estimated in the female broodstock of both TR and SR. The ...

Introduction: The production of Reaction Oxygen Species (ROS), lowers cellular antioxidant levels, and enhances oxidative stress in many tissues, especially the liver. Efficient liver function is extremely important to the overall health. The key to helping prevent long-term damage is to decrease oxidative stress. The purpose of this study was to assess the effects of treadmill training with vi...
