- چکیده:
- چکیده انگلیسی: Background: Adjustment is considered as one of the most important signs of mental health and well-being; it refers to any kind of healthy or unhealthy, conscious or unconscious attempt to prevent or weaken the stressors and ability to tolerate hard situations. One of the variables probably involved in adolescent adjustment is the family communication patterns which include two important dimensions: conversation pattern and conformity pattern. The present study aimed to explain the relationship between the family communication patterns and adolescent adjustment and investigate the predictive role of family communication patterns.
Methods: This study is correlational research and the study population consisted of all male and female students of the high schools in Shiraz, Iran, during the academic year of 2019-2020. Sample size was determined by Cochran formula with a significance level of 0.05. Through multistage sampling method, six schools from each of the four districts were selected; three classes were then chosen from each high school. Finally, five to six random students were selected from each class to answer the questionnaires. The sample consisted of 380 high school students (210 girls and 170 boys). We used the family communication patterns questionnaire; it is a self-report scale examining the agreement or disagreement level of the respondents based on a five-point Likert scale regarding 26 items on family communication. Multidimensional adjustment scale was further applied. This scale includes 15 items and five components, namely personal, social, educational, occupational, and family. The extracted data were analyzed using descriptive and inferential statistics including Pearson correlation coefficient and multiple regression statistics in SPSS version 21.
Results: Conformity communication pattern had a significant negative relationship with adjustment (Beta=-0.48, P=0.001); meanwhile, there was a significant positive relationship between conversation pattern and adjustment (Beta=0.36, P=0.001), both predicting 55% of the variance in adolescents adjustment.
Conclusion: The dimensions of family communication patterns predicted adolescent adjustment and conversation communication pattern had positive and conformity communication pattern had negative relationship with adolescent adjustment.- انتشار مقاله: 22-04-1399

- چکیده انگلیسی: Background:
Melanogenesis begins with the oxidation of L-tyrosine to L-Dopa by tyrosinase. Inhibition of tyrosinase could be effective in treatment of complications such as skin lesions, eczema and melasma. Inhibition of tyrosinase could be effective in treatment of those complications. The aim of this study was to determine inhibitory activity on tyrosinase and antioxidant activity of Astragalus siliquosus Bioss. and Verbascum phoeniceum L.
Methods:
Methanol extracts of organs of the plants were prepared by maceration. Inhibitory effects of the extracts were evaluated in 96 wells at 492 nm wavelength. The antioxidant activity of the extracts was evaluated using DPPH free radical scavenging index and iron reduction test.
Results;
For A.siliquosus, maximum inhibitory activity was of its flower extract (97% inhibition and IC50=1.58 mg/ml) and of its stem extract (100 % and IC50=2.1 mg/ml). For V.phoeniceum, the highest inhibitory activity was of its leaf extract (87% inhibition and IC50=3.2 mg/ml). Flower extract of A.siliquosus showed mixed Uncompetitive-Non-competitive pattern of inhibitory activity, while the extract of the V.phoeniceum leaf showed mixed Competitive-Non-competitive inhibitory pattern. All aerial parts of the A.siliquosus had 100% antioxidant activity with EC50s of 0.089, 1.78, 1.25 mg/ml for its flower, leaf and stem respectively. Leaves of the V.phoeniceum had a 100% antioxidant activity, with EC50 of 0.013 mg/ml.
Conclusions:
Methanol extracts of flower and leaf organs of A.siliquosus, and leaf organ of V.phoeniceum, had a reasonable inhibitory effect on tyrosinase activity. Feature studies could be focused on those organs to separate potential agents with pharmaceutical and cosmetic applications.- انتشار مقاله: 14-07-1398

- کلمات کلیدی: Aspergillus species,Otomycosis,Caspofungin,Antifungals
- چکیده:
- چکیده انگلیسی: Background and Purpose: Otomycosis is a secondary ear fungal infection among predisposed individuals in humid conditions. Aspergillus species are the most common etiologic agents of this infection. Several ototopical antifungals are currently used for the treatment of this disease; however, recurrence and treatment failure are usually observed in some cases. Regarding this, the present study was conducted to investigate the antifungal activity of caspofungin, azoles, and terbinafine against the isolated agents of otomycosis.
Materials and Methods: This study was conducted on the specimens collected from 90 patients with otomycosis. The samples were cultured on Sabouraud dextrose agar and identified based on morphological characteristics, physiological tests, and microscopic features. Furthermore, the microdilution method was used for antifungal susceptibility testing according to the Clinical and Laboratory Standards Institute (CLSI) guidelines. Finally, the minimum inhibitory concentration (MIC) and minimum effective concentration (MEC) ranges, MIC/MEC50, MIC/MEC90, and geometric mean (GM) MIC/MEC were calculated for the isolates.
Results: According to the results, 77 patients with otomycosis were positive for different Aspergillus (88.3%) and Candida (11.7%) species. Aspergillus niger complex (n=36) was found to be the most common agent, followed by A. flavus, A. terreus, and A. nidulans complexes. Furthermore, epidemiological cutoff values (ECVs) were lower than those presented by the CLSI for itraconazole and caspofungin in 98.5% and 42.6% of Aspergillus species, respectively. Terbinafine exhibited a great activity against Aspergillus species, while fluconazole revealed a low activity against both Aspergillus species. Based on the results, 77.8% of Candida species were resistant to caspofungin; however, miconazole and econazole had low MIC ranges.
Conclusion: Aspergillus niger and A. flavus complexes were identified as the most common agents accounting for 85.7% of the isolates. In addition, terbinafine was identified as the best antifungal for both Aspergillus and Candida species. Moreover, tested azoles had relatively low MICs, whereas most of the isolates had the MIC values beyond the caspofungin ECVs.- انتشار مقاله: 14-09-1398

- چکیده:
- چکیده انگلیسی: Background and Purpose: Candida glabrata is the second cause of candidiasis. The mortality rate of C. glabrata infections is about 40%; accordingly, it may be life threatening, especially in immunocompromised hosts. Regarding this, the current study was conducted to evaluate the regional patterns of the antifungal susceptibility of clinical C. glabrata isolated from the patients referring to the health centers located in Ahvaz, Iran.
Materials and Methods: In this study, a total of 30 clinical strains of C. glabrata isolates were recovered from different body sites (i.e., vagina, mouth, and urine). Phenotypic characteristics and molecular methods were used to identify the isolates. The minimum inhibitory concentration (MIC) was determined according to the European Committee on Antimicrobial Susceptibility Testing.
Results: Our findings demonstrated that 20%, 80%, and 6.7% of the isolates were resistant to amphotericin B, terbinafine, and posaconazole, respectively, while all the isolates were found to be fluconazole susceptible dose dependent and susceptible to voriconazole and caspofungin.
Conclusion: Our study suggested that voriconazole had high potency against C. glabrata isolates. Consequently, this antifungal agent can be an alternative drug in the treatment of resistant patients. These results can be helpful for the successful treatment of patients in different regions.- انتشار مقاله: 29-06-1398

- چکیده:
- چکیده انگلیسی: Background and Purpose: Ozone is an inorganic molecule with effective antimicrobial properties. Clinical treatment of ozonated water was used for the elimination of Candida albicans, Enterococcus faecalis, endotoxins, and biofilms from root canals. In addition, its therapeutic effects for tinea pedis, ulcers, and leishmaniasis were investigated. The purpose of the present study was to evaluate the fungicidal effects of ozone on different forms of C. albicans. In addition, antifungal susceptibility profile of strains was assessed before and after exposure to ozone.
Materials and Methods: Fifty strains of C. albicans were exposed to gaseous ozone at different times. Furthermore, biofilm formation and germ tube production were evaluated when yeast suspensions were exposed to ozone. In addition, antifungal susceptibility of ozone resistant colonies was investiagted as compared to controls.
Results: Ozone was highly effective in killing C. albicans in yeast form and inhibition of germ tube formation during 210 and 180 s, respectively. Although with increasing exposure time biofilm production was considerably decreased, resistance to ozone was much higher among vaginal and nail isolates even after 60 min. All the strains were sensitive to fluconazole, caspofungin, and terbinafine pre- and post-ozone exposure. Resistance to amphotericin B was significantly enhanced after exposure to ozone.
Conclusion: Although ozone was highly effective on the yeast form of C. albicans and it can inhibit the formation of germ tubes in C. albicans, the complete removal of biofilms did not happen even after 60 min. It seems that ozone therapy induces resistance to amphotericin B.- انتشار مقاله: 18-04-1398

- چکیده:
- چکیده انگلیسی: The basidiomycetous yeast genus Cryptococcus contains two medically important pathogens, Cryptococcus neoformans and C. gattii [1-3]. C. neoformans is one of the common pathogens in acquired immunodeficiency syndrome (AIDS), whereas the most cases of diseases due to C. gattii happened in the healthy individuals [2, 4]. C. gattii has a tendency to affect the respiratory and nervous systems of the humans and domestic animals such as, dogs, cats, and horses [5]. C. gattii is more geographically restricted than C. neoformans and is largely confined to tropical and subtropical regions. Several reports show that C. gattii was isolated from Eucalyptus trees (Eucalyptus tereticornis, E. citriodora and E. camaldulensis) in Australia [4, 6, 7].
