This study aimed to investigate the relationship between the occupational noise exposure and the hearing loss caused by working in small-scale service industries in the city of Damavand, close to the metropolitan capital city of Tehran, Iran. \u0000Methods: This descriptive cross-sectional study investigated the occupational noise levels within the 90 small-scale industries (mainly service industries and workshops) working under the supervision of Damavand healthcare network governed by the Iranian ministry of health and medical education. A sound level meter (Bruel and Kjaer 2250) was employed to determine the noise \u0000exposure levels based on the dB A, and according to the standard ISO 9612: 2009. The audiometric exam tests were performed by an audiometer (model MEVOX SA-900). The obtained data were then analysed by SPSS 16, using linear regression and t-test. \u0000Results: The highest measured 8-hour equivalent continuous sound pressure levels (Leqs) were associated with auto body mechanics (89.2 dB A), foundry and casting workers (88.8 dB A), aluminium products fabrication workers (86.32 dB A), blacksmiths and forging (85.8 dB A) carpenters (84.93 dB A), and cabinet manufacturers, respectively (84 dB A). Results from the hearing threshold shifts of the workers from the studied occupational groups revealed that the highest work related hearing loss associated with the right \u0000ear occurred among the auto body mechanics, aluminium products fabrication workers and carpenters. However, the most significant work-related hearing loss associated with the left ear was noticed among carpenters, aluminium products fabrication workers, and auto body mechanics, respectively. Pearson correlation coefficient was tested between Leqs, work experience and hearing loss, \u0000and the results implied that the progress of workers’ hearing loss was correlated with the increase in work history and experience. \u0000Conclusions: The 8-hour Leqs and work experience were, respectively, the most important factors affecting the rate of hearing loss among the participants of this study. \u0000Keywords: Noise-Induced Hearing Loss, Sound Pressure Level, Small-Scale Industries","PeriodicalId":8849,"journal":{"name":"Biotechnology and Health Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74972110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To recognize the mechanism of MT action, it is important to investigate its inhibition, activation, mutation, and modification properties. Objectives: In this study, the chemical modification of MT tryptophan residues was carried out by using N-bromosuccinimide (NBS) and then, the activity, stability, and structure of the native and modified enzymes were compared. Methods: Chemical modification of MT tryptophan residues was accomplished by enzyme incubation with different concentrations of NBS. The relative activity of native and modified MT was investigated through catecholase enzyme reaction in presence of dihydroxyphenylalanine (L-Dopa) as substrate. Thermodynamic parameters including standard Gibbs free energy change (∆G25°C) and Melting temperature (Tm) were obtained from thermal denaturation of the native and modified enzymes. The circular dichroism and intrinsic fluorescence techniques were used to study secondary and tertiary structure of MT, respectively. All experiments were conducted in 2015 in biophysical laboratory of Qazvin University of Medical Sciences and Islamic Azad University, Science and Research Branch, Tehran. Results: The relative activity reduced from 100% for native enzyme to 10%, 7.9%, and 6.4% for modified MT with different NBS of concentrations 2, 10, and 20 mM, respectively. Thermal instability of modified enzyme was confirmed by decreased Tm and ∆G25°C values after modification. In accordance with kinetic and thermodynamic results, the lower stability of modified MT was observed from the changes occurred on its secondary and tertiary structures. Conclusions: Chemical modification of tryptophan residues with NBS reduces the activity and stability of MT simultaneously with its structural change. Thus, this study emphasizes the crucial role of tryptophan residues in the structure-function relationship of MT enzyme.","PeriodicalId":8849,"journal":{"name":"Biotechnology and Health Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84624327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Documented history is an important tool to diagnose diseases at each stage. The first and fundamental step in diagnosis is a comprehensive \u0000clinical interview. \u0000Objectives: The current study aimed to investigate the concordance of mental disorders diagnosed by psychiatrist’s clinical interviews and results of thematic apperception test (TAT) conducted by psychologists. \u0000Methods: It was a cross sectional descriptive-analytical study. The study population included the patients (male and female) admitted in psychiatry section of Dr. Fatemi hospital in Ardabil, Iran, during 2009-2010. Data were collected from the archive of Ardebil Dr. Fatemi hospital and about 1200 patients were studied. Demographic data of participants including age, gender, marital status, \u0000admission date, discharge date and type of insurance were gathered from the recorded documents. The initial diagnosis of psychologist using TAT test was compared with the final diagnosis recorded for the patient attended by physicians.

Objectives: The current study aimed to determine the degree of establishment of accreditation standards using logical framework of Zachman. Methods: This descriptive research was conducted during year 2015. The population of the study included people involved in the establishment of accreditation standards. Sampling was conducted in the form of complete enumeration according to 36 standards of accreditation. The instrument used for data collection was the “Logical framework of Zachman”. Columns of framework consisted of people involved in conducting the work (Who), the purpose of the work (Why), strategy of the work (What), work time (When), and sub-system of doing work (Where) and way of doing work (How), and rows of framework included the view of hospital chief, director/assistants of hospital, officials and personnel. Test chi-square was used to compare between accreditation standards text and studied hospital gap. Descriptive statistical method was used for variables. Results: People involved in doing work and sub-systems of doing work at the hospital were consistent with specified accreditation standards. In 27% of the standards, time interval of doing work in the hospital was not conducted according to accreditation standards. In terms of way of doing work, 25% of standards had not been established, and 26% of them had been established incompletely. During interviews, it was found that 59% of personnel of purpose of doing work, and 94% of them are not informed about the strategy of doing work, according to accreditation standards in the hospital. Conclusions: Uncertainties in the accreditation standards in dimensions of purpose, people involved, strategy and time interval of doing work, respectively, led to a lack of understanding the intention of author/developers of standards by personnel. As a result, this led to lack of complete establishment of accreditation standards in the studied hospital.

Methods: In a prospective study, 187 patients with UTI and suggestive signs and symptoms were included. History of UTI and clinical findings were recorded. Urine specimens were cultured and analyzed for pyuria by sediment microscopy and nitrite using a test strip. The systemic inflammatory response was assessed by ESR, and total white blood cell count. Results: Escherichia coli accounted for 62.2% of the urinary isolates. Most UTI patients showed a decline three days after treatment, whereas some had an increased ESR response at this time (despite improvements in clinical symptoms). Overall, ESR on the sixth day was determined to be a better marker for response to symptomatic UTI treatment than the third day ESR. Conclusions: This study showed that ESR and clinical findings were not interchangeable indexes of patient's condition, although they are concordant (both normal and both abnormal) in the vast majority of patients. Erythrocyte sedimentation rate is frequently misleading in patients with UTI and is not responsive to changes in the patient's condition.

Shift work and job satisfaction are considered two of the occupational risks for burnout in nurses. Nurses have stress and health complaints. In addition, nurses are likely to job burnout. \u0000Objectives: The current study aimed to determine the prevalence of job burnout and its association with work schedules and job satisfaction among Iranian nurses in a public hospital. \u0000Methods: This cross-sectional study was conducted in one of the largest Iranian public hospitals among 362 nurses (response rate: 80.44%) in Tehran, Iran. The Maslach burnout inventory (MBI-22) and demographic factors questionnaire were used in the present study. The relationship between job burnout with work schedules and job satisfaction was investigated with multiple logistic regression analysis. \u0000Results: The mean age and work experience of the participants were 36.14 ± 8.59 and 15.23 ± 9.30 years, respectively. The result indicated a relatively high prevalence of burnout (particularly, personal accomplishment) among the study population. In general, \u000064.4% of participants reported low personal accomplishment level. The nurses engaged in shift work reported higher levels of emotional exhaustion (odds ratio (OR) = 1.02, 95% confidence interval (CI) = 1.006 - 1.041, P-value = 0.008); there was no relationship \u0000between workschedules with depersonalization and personal accomplishment.
