Background and Aim: Tarragon (Artemisia dracunculus L. ) has antioxidant, anti-inflammatory and analgesic effects. The objective of this study was to investigate the effect of Tarragon alcoholic extract on spatial learning and memory deficits, induced by chronic immobilization stress in male rats. Materials and Methods: In this experimental study, 60 male Wistar rats were divided into 6 groups (each group of 10 rats): Control(without treatment), under stress, receiving 100 mg / kg Tarragon extract, receiving 500 mg / kg Tarragon extract, stress receiving and 100 mg / kg Tarragon extract simultaneously, and finally Stress receiving group and 500 mg / kg tarragon extract simultaneously. The rats in under stress group, 6 hours every day for 21 consecutive days they encountered with immobilized stress. Groups receiving Tarragon extract, during this period, the doses of 100 mg / kg. bw and 500 mg / kg. bw were extracted by gavage, and two groups receiving the extract and stress simultaneously, in addition to receiving Tarragon extract at the same doses they also faced stress. Spatial learning and memory of animals were evaluated by using the Morris Water Maze test. Results Immobilized stress impaired learning and memory in animals. Delay time (seconds) and distance (cm) moved to reach the hidden platform was significantly increased in the stress group compared to the control group (P <0. 01 and P <0. 05, respectively). Also in probe test, total elapsed time (s) and distance (cm) in target quadrant decreased significantly in stress group compare with control group (p<0. 001 and p<0. 05 respectively). Receiving both doses of Tarragon extract improved spatial learning and memory in under stressed rats. Conclusion: The results of this study indicate that Tarragon extract prevent memory impairment and may be useful in preventing and treating of neuro-degenerative diseases due to stress.

Background and Aim: The residuals of drug are belonging to emerging pollutants. Drugs and their metabolites should be removed from water resources due to potential risks and their toxicities for humans and the environment. These materials are not completely eliminated by the conventional methods of water and wastewater treatment. The purpose of this study was to investigate the removal of acetaminophen using single-walled and multi-walled carbon nanotubes from aqueous environments. Materials and Methods: In this experimental study, the effect of different parameters such as: pH, initial concentration of acetaminophen, adsorbent dose, time of touch and mixing speed were investigated in acetaminophen removal by single-wall and multi-wall carbon nanotubes. The adsorption isotherms of Langmuir, Freundlich, Temkin, Dubinin-Rudeshkuvich and BET and pseudo-first and pseudo-second order adsorption kinetics were also investigated. Acetaminophen concentration was measured by spectrophotometer at (λ max = 258 nm). Results: The result of the experiments showed that single-wall and multi-wall carbone nanotubes could be able to removal 38. 59% and 28. 24% of acetaminophen at time=45 min, PH=7. With increasing the dose of nanotubes, the removal percentage increased and absorption capacity decreased, Absorption process showed the highest correlation with Langmuir model and pseudo-second kinetics (R2>0. 99). Conclusion: The results showed that single-walled and multi-walled carbon nanotube adsorbents can be used as an effective adsorbent in the removal of acetaminophen from aqueous environments along with other treatment methods.

Background and Aim: A successful marriage is often accompanied by both partner consent to sex, on the other hand, the structure of a balanced family is based on sound marital relations.
