- چکیده:
- چکیده انگلیسی: Stock return is usually considered to be affected by firm’s financial ratios as well as economic variables. Fundamental method assume that stock returns is not solely related to the stock market. Most result come from the company condition , industry situation and whole economy. In this paper, this relationship between stock return and fundamentals is studied using the data for 22 pharmaceutical companies in Tehran Stock Exchange over a 7 year period, and effective factors on stock return are investigated. Because of our data natural we used panel data model from econometric methods. The results show that 80 percent of change in stock return can be explained with 9 fundamental variables factors including debt-equity ratio, working capital to total asset, current ratio, net profit margin, operating cycle, market share, inflation rate of medicinal products prices, total asset, and exchange rate have significant effect on stock return. This factors can be used in decision making in pharmaceutical industry.

- چکیده:
- چکیده انگلیسی: Lichen planus pigmentosus (LPP) develops as an asymptomatic and dusky pigmentation of the facial skin with no effective treatment. Herein we report a 54-year-old lady with clinical and histopathologic confirmation of LPP who was scheduled to be treated with CO2 laser resurfacing. After tumescent anesthesia, the whole facial skin was treated with three passes of Ultrapulse conventional CO2 ablation. The energy used in the first, second, and third passes were 6.6, 5.4, and 4.8 mJ, respectively. The mandibular area was treated with two passes (4.2 and 3.6 mJ). The eye contours were treated with two passes (3.9 and 3.3 mJ). The patient’s face remained edematous for a week, with the facial skin oozing within the first three days before it became crusted. The crust shed out from day three to six. After a week, smooth and erythematous skin appeared. The erythema persisted for up to four months, after which uniform skin with considerable bleaching and rejuvenation developed. No recurrence occurred within 18 months of follow-up. We conclude that LPP can be treated with CO2 laser resurfacing without any complications.

- چکیده:
- چکیده انگلیسی: The patients with universal vitiligo and residual pigmented patches usually do not benefit from available repigmenting methods and are better scheduled for depigmentation by medical, laser,
and or freezing procedures. A 37-year-old lady with universal vitiligo and remaining pigmentation in the left anterior chest wall, both ventral forearms, and diffuse mottled depigmentation of the face was scheduled for facial depigmentation by 532 nm Q-switched Nd-YAG laser. All residual pigmented facial areas were treated uniformly. Two months after laser therapy, we paradoxically observed considerable repigmentation of the treated areas with only some remaining scattered and round depigmented patches. Through an unknown mechanism, a true reverse Koebner phenomenon with its resultant repigmentation rather than depigmentation was observed in our patient.- انتشار مقاله: 04-10-1398

- چکیده:
- چکیده انگلیسی: Effect of temperature on hydrodynamics of bubbling gas-solid fluidized beds was investigated. Experiments were carried out in the range of 25-600 ºC and different superficial gas velocities in the range of 0.17-0.78 m/s with sand particles. Time-position trajectory of particles was obtained by radioactive particle tracking technique. These data were used for determination of mean velocities of upward-moving (including bubble wake and ascending clusters) and downward-moving (descending clusters) particles. It was found that the upward velocity increases by increasing temperature up to 300 ºC, however, it decreases by further increase in temperature. Due to the wall effect, there is no significant change in the mean velocity of downward-moving clusters. The change in hydrodynamic parameters with temperature can be a consequence of changing physical properties of the bed which have been represented by Reynolds number in this study.

- چکیده:
- چکیده انگلیسی: Background: Medications nowadays have been commonly used items in the world and are sometimes available without prescription. This causes a range of effects on public health. This study evaluated the frequency and the involved factors of uncontrolled prescription drugs consumption.
Methods: The present study is a cross-sectional study on 1,000 citizens of Tehran between 2016 and 2017. The various factors such as age, gender, and educational background have been carefully surveyed. The questionnaires were presented to interested people in printed form. For analyzing the data, descriptive statistics and analytical statistics were performed using SPSS software version 19.
Results: 67% of participants use OTC drugs and 34% of them were between 20 and 30 years old. Although 12% of the OTC pills were used regularly as a pain killer, 95% of the people did not know anything about the side effects of the drugs. Moreover, 45% used the pill to relieve the common and acute pain and 34% of people lived in poverty and 12% suggested lack of adequate time as a reason to refuse visiting a doctor.
Conclusion: Self-administered drug is one of the problems in the medical field. Headache is the main reason of self-medication. In the other hand, drug resistance is also rising among repeated drug users. According to the results, public education, the prohibition of the sale of some high-risk drugs and the reduction of drug doses are ways to prevent the development of such high-risk habits.
