Abstract
Background and Aim: Aspergillosis are the most prevalent cause of the respiratory infections. These fungi show invasive aspergillosis(IA) in immunocompromised patients. The number of immunocompromised patients are increasing due to immunodisorder illnesses, grafts and immunosuppressor drugs, so, rapid identification methods are very important. The aim of this study was to detect the Aspergillus spp. In fluid samples by nested PCR, and compare with culture and direct smear.
Materials and Methods: Conventional detection methods such as culture and direct smear are unsensitive and time consuming. Some methods such as immunodetecting methods have high false positive and are unreliable. Nowadays, molecular methos and PCR are very helpful. These methods are both sensitive and reliable and very rapid. In this study, we used Nested PCR, culture and direct smear to detect Aspergillus spp in BAL fluid samples.
Results: This research is a descriptive-comparative study and has been done for rapid identification of fungi related to Aspergillosis such as culture, direct smear and nested- PCR. Findings of this study show that positive results by nested-PCR were more effective and sensitive than culture and direct smear.
Conclusions: We found that positive results by PCR were more effective and sensitive than two other methods.

Abstract
Background and Aim: Based on theories and researches, two variables effective in the continuous improvement of services are trust in and identification with hospital goals. The present study aims to explore the relationship between such variables among nursing staff members in private hospitals of Shiraz.
Materials and Methods: This research is a cross-sectional correlation study. Some 340 nurses(58 males and 282 females) were selected using the stratified sampling technique.
Three questionnaires for the assessment of identification with hospital goals, measurement of continuous improvement, and determination of trust in hospital were used. The reliability of data collection devices turned out to be 0.70, 0.70 and 0.79, respectively. Besides, the construct validity was confirmed through factor analysis. Data were analyzed inferentially using Pearson's correlation test and hierarchical regression analysis.
Results: The findings show that the relationship between identification with hospital goals and trust and nurses' effort to improve continuously is positive and significant. Moreover, the results of hierarchical regression analysis show that after controlling gender, age, experience and education, first identification with hospital goals and then trust in hospital play a significant role in the effort to improve continuously.
Conclusion: Nurses' effort to improve continuously is mostly influenced by identification with hospital goals rather than trust in hospital.

Abstract
Background and Aim: Female pattern hair loss(female androgenic alopecia) is a common but puzzling condition in women which increases by aging. Female hair loss is strongly linked to hormones and hormonal imbalances. The aim of this study was to determine the serum level of hormones such as T4, TSH, free testosterone, Prolactin(PRL) and Alb, SHBG in women(15-50 years old) with hair loss versus those without hair loss.
Materials and Methods: In this cross-sectional case-control study, 71 women with hair loss and 70 normal women were selected from skin and hair care day clinics. The level of hormones and SHBG were measured by ELISA, and Alb was measured by spectrophotometery. Data were analyzed by independent t-test.
Results: After analyzing the data and determining the levels of TSH, T4, Prolactin, Alb, SHBG, no significant difference was found between the case and control groups. However, free Testosterone level was significantly different between patients and controls(P= 0.000), with a higher mean level in the case group(patients).
Conclusion : Since androgens have a major role in regulating the biological cycle of hair in women and since there was a significant difference between free testosterone in patient and control groups, we suggest that the serum level of free testosterone should be measured in women with androgenic alopecia .

Abstract
Background and Aim: Infertility is a major problem of modern medicine as it affects almost 20% of reproductive-aged couples. The cause of this problem is attributed to the male partner in nearly 40%-50% of these cases. The role of herpes simplex virus (HSV) in male infertility has been investigated using the sensitive methods. The aim of this study was to determine the prevalence of HSV-1, 2 DNA in the semen, blood and urine of idiopathic infertile men and its association with altered semen parameters.
Materials and Methods: A total of 150 semen, blood and urine samples from infertile men were collected in the Shariati hospital, Tehran (2012-2014). Sample analysis and diagnostic PCR using specific primers was performed for detection of HSV-1, 2 DNA in the specimens.
Results: Analysis showed six groups of infertile men, including HSV-1, 2 positive and negative groups in semen, blood and urine samples. HSV-1, 2 DNA was detected in 38 (18.66%) semens, (6.66%) 10 in blood and 2 (1.33%) in urine. Only HSV-1, 2 positive samples of semen had abnormal semen parameters.
Conclusion: Using a powerful molecular method, we detected a high prevalence of HSV-1, 2 DNA in the semen of asymptomatic infertile patients. Although HSV-1, 2 infections were not associated with motility and morphology defects of the sperms, it was related with decreased sperm count in the semen fluid. In addition there was not a significant role for detection of HSV-1, 2 DNA in blood and urine samples of infertile men and abnormal semen parameters.
