    2016-01-01

    Objective: We determined cause-specific mortality prevalence and risks of Gulf War deployed and nondeployed veterans to determine if deployed veterans were at greater risk than nondeployed veterans for death overall or because of certain diseases or conditions up to 13 years after conflict subsided. Methods: Follow-up began when the veteran left the Gulf War theater or May 1, 1991, and ended on the date of death or December 31, 2004. We studied 621   901 veterans who served in the 1990-1991 Persian Gulf War and 746   247 veterans who served but were not deployed during the Gulf War. We used Cox proportional hazard models to calculate rate ratios adjusted for age at entry to follow-up, length of follow-up, race, sex, branch of service, and military unit. We compared the mortality of (1) Gulf War veterans with non–Gulf War veterans and (2) Gulf War army veterans potentially exposed to nerve agents at Khamisiyah in March 1991 with those not exposed. We compared standardized mortality ratios of deployed and nondeployed Gulf War veterans with the US population. Results: Male Gulf War veterans had a lower risk of mortality than male non–Gulf War veterans (adjusted rate ratio [aRR] = 0.97; 95% confidence interval [CI], 0.95-0.99), and female Gulf War veterans had a higher risk of mortality than female non–Gulf War veterans (aRR = 1.15; 95% CI, 1.03-1.28). Khamisiyah-exposed Gulf War army veterans had >3 times the risk of mortality from cirrhosis of the liver than nonexposed army Gulf War veterans (aRR = 3.73; 95% CI, 1.64-8.48). Compared with the US population, female Gulf War veterans had a 60% higher risk of suicide and male Gulf War veterans had a lower risk of suicide (standardized mortality ratio = 0.84; 95% CI, 0.80-0.88). Conclusion: The vital status and mortality risk of Gulf War and non–Gulf War veterans should continue to be investigated. PMID:28123229

    Differences in the characteristics and mental health needs of female veterans of the Iraq/Afghanistan war compared with those of veterans of other wars may have useful implications for VA program and treatment planning. Female veterans reporting service in the Iraq/Afghanistan war were compared with women reporting service in the Persian Gulf and Vietnam wars and to men reporting service in the Iraq/Afghanistan war. Subjects were drawn from VA administrative data on veterans who sought outpatient treatment from specialized posttraumatic stress disorder (PTSD) treatment programs. A series of analyses of covariance (ANCOVA) was used to control for program site and age. In general, Iraq/Afghanistan and Persian Gulf women had less severe psychopathology and more social supports than did Vietnam women. In turn, Iraq/Afghanistan women had less severe psychopathology than Persian Gulf women and were exposed to less sexual and noncombat nonsexual trauma than their Persian Gulf counterparts. Notable differences were also found between female and male veterans of the Iraq/Afghanistan war. Women had fewer interpersonal and economic supports, had greater exposure to different types of trauma, and had different levels of diverse types of pathology than their male counterparts. There appear to be sufficient differences within women reporting service in different war eras and between women and men receiving treatment in VA specialized treatment programs for PTSD that consideration should be given to program planning and design efforts that address these differences in every program treating female veterans reporting war zone service.

    Differences in the characteristics and mental health needs of veterans of the Iraq/Afghanistan war when compared with those of veterans who served in the Persian Gulf war and in the Vietnam war may have important implications for Veterans Affairs (VA) program and treatment planning. Subjects were drawn from administrative data bases of veterans who sought treatment from specialized VA programs for treatment of posttraumatic stress disorder (PTSD). Current Iraq/Afghanistan veterans were compared with 4 samples of outpatient and inpatient Persian Gulf and Vietnam veterans whose admission to treatment was either contemporaneous or noncontemporaneous with their admission. A series of analyses of covariance was used hierachically to control for program site and age. In analyses of contemporaneous veterans uncontrolled for age, Iraq/Afghanistan veterans differed most notably from Vietnam veterans by being younger, more likely to be female, less likely to be either married or separated/divorced, more often working, less likely to have ever been incarcerated, and less likely to report exposure to atrocities in the military. Regarding clinical status, Iraq/Afghanistan veterans were less often diagnosed with substance abuse disorders, manifested more violent behavior, and had lower rates of VA disability compensation because of PTSD. Differences are more muted in comparisons with Persian Gulf veterans, particularly in those involving noncontemporaneous samples, or those that controlled for age differences. Among recent war veterans with PTSD, social functioning has largely been left intact. There is a window of opportunity, therefore, for developing and focusing on treatment interventions that emphasize the preservation of these social assets.

    To test the psychometric properties of the Persian version of Zarit Burden Interview (ZBI-12) in the Iranian population. After translating and cultural adaptation of the questionnaire into Persian, 100 caregiver spouses of Iran- Iraq war (1980-88) veterans with chronic spinal cord injury who live in the city of Mashhad, Iran, invited to participate in the study. The Persian version of ZBI-12 accompanied with the Persian SF-36 was completed by the caregivers to test validity of the Persian ZBI-12.A Pearson`s correlation coefficient was calculated for validity testing. In order to assess reliability of the Persian ZBI-12, we administered the ZBI-12 randomly in 48 caregiver spouses again 3 days later. Generally, the internal consistency of the questionnaire was found to be strong (Cronbach's alpha 0.77). Intercorrelation matrix between the different domains of ZBI-12 at test-retest was 0.78. The results revealed that majority of questions the Persian ZBI_12 have a significant correlation to each other. In terms of validity, our results showed that there is significant correlations between some domains of the Persian version the Short Form Health Survey -36 with the Persian Zarit Burden Interview such as Q1 with Role Physical (P=0.03),General Health (P=0.034),Social Functional (0.037), Mental Health (0.023) and Q3 with Physical Function (P=0.001),Viltality (0.002), Socil Function (0.001). Our findings suggest that the Zarit Burden Interview Persian version is both a valid and reliable instrument for measuring the burden of caregivers of individuals with chronic spinal cord injury.

    2017-12-14

    The single most important question in radiation epidemiology is determining the level of health risks associated with radiation exposures that occur gradually over time. The study of one million early U.S. radiation workers and veterans has been designed to provide information on risk following chronic exposures by focusing on occupational groups with differing radiation exposure patterns, including intakes of radionuclides. The cost-efficient study builds on the investments made and foundations laid by investigators and government agencies over the past 30-40 years, which have established early worker cohorts that can now provide answers to questions on the lifetime human health risks associated with low-level radiation exposures. Within the overall goal of the epidemiologic study of one million U.S. radiation workers and veterans, this project had a total of nine specific aims which included studies of six populations for multiple endpoints including cancer overall mortality, leukemia and non-cancer mortality. The six populations included: Mound, Ohio, workers exposed to polonium, tritium and plutonium; nuclear power plant workers within the Landauer dosimetry and Nuclear Regulatory Commission data files; industrial radiographers; Mallinckrodt uranium workers; uranium workers who linked with the US Renal Data System; and nuclear weapons test participants. Over 400,000 workers and atomic veterans are included in these populations, with vital status being determined and analyses of all causes of death undertaken. A critical, integral component of the studies has been comprehensive evaluations of dosimetry involving, in many cases, complex dose reconstructions, and assessments of uncertainties. The work has also involved development of state-of-the art statistical approaches and modeling. All nine aims were accomplished successfully, resulting in publication of two NCRP documents, 13 literature papers, numerous Boice Reports in Health Physics News and many

    Diverse veteran's perspectives on the accessibility and acceptability of the Department of Veteran Affairs (VA) health services are presented. The qualitative methodology uses 16 focus groups (N = 178) stratified by war cohort (World War II and Korean Conflict versus Vietnam War and Persian Gulf War) and four ethnic/racial categories (African American, Asian American, European American, Hispanic American). Five themes emerged regarding veterans' health care expectations: (1) better information regarding available services, (2) sense of deserved benefits, (3) concern about welfare stigma, (4) importance of physician attentiveness, and (5) staff respect for patients as veterans. Although veterans' ethnic/racial backgrounds differentiated their military experiences, it was the informants' veteran identity that framed what they expected of VA health services. Accessibility and acceptability of VA health care is related to veterans' perspectives of the nature of their entitlement to service. Provider education and customer service strategies should consider the identified factors to increase access to VA as well as improve veterans' acceptance of the care.

  16. Mindfulness-based stress reduction for veterans exposed to military sexual trauma: rationale and implementation considerations.

    Gallegos, Autumn M; Cross, Wendi; Pigeon, Wilfred R

    2015-06-01

    Military sexual trauma (MST) represents a significant public health concern among military personnel and Veterans and is associated with considerable morbidity and suicide risk. It is estimated that 22% of Veteran women and 1% of Veteran men experienced sexual assault or repeated, threatening sexual harassment during their military service. Exposure to traumatic stress has detrimental effects on emotion regulation, which refers to a set of strategies used to modulate different components of emotion at different points on the trajectory of an emotional response. Mindfulness-based interventions offer approaches to health that focus on mind and body practices that can help regulate the experience and expression of difficult emotions. Mindfulness-based stress reduction (MBSR) is an evidence-based therapy shown to be effective for depression, anxiety, and post-traumatic stress disorder. This article discusses the rationale for providing MBSR to Veterans who have been exposed to MST. The article also discusses ways to facilitate implementation of this practice in the U.S. Department of Veterans Affairs health care system. We address potential barriers to care and ways to facilitate implementation at the patient, provider, organization/local, and policy levels. MBSR is likely to be an important component of a comprehensive approach to care for Veterans exposed to MST. Reprint & Copyright © 2015 Association of Military Surgeons of the U.S.

    Between 1961 and 1971, the United States Air Force sprayed 12 million gallons of the defoliant ''Agent Orange'' on 3.6 million acres of Vietnam. Agent Orange was a 1:1 mixture of 2,4-dichlorophenoxyacetic acid and 2,4,5- trichlorophenoxyacetic acid, and 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) was a contaminant of the defoliant, from less than 0.05 to almost 50 parts per million. Numerous Vietnam veterans were exposed to TCDD when Agent Orange and other TCDD-contaminated herbicides were sprayed in large quantities in Vietnam and TCDD has been found at many toxic waste disposal sites in the United States. Some of the highest exposure to TCDD occurred in members of Operation Ranch Hand, the Air Force unit responsible for spraying herbicides from fix-wing aircraft in Vietnam. The Air Force Health Study (AFHS), an epidemiological study of Ranch Hand veterans, was launched in 1980 to address veteran concerns regarding Agent Orange exposure. A link between TCDD and diabetes has been demonstrated in several studies. Among the Ranch Hand veterans with high blood levels of TCDD, there was a significant increase in the prevalence of diabetes and a decrease in the age at which diabetes was diagnosed. In a study from Seveso, Italy, where 45,000 people had varying levels of exposure to TCDD, there were significant increases in mortality from coronary artery disease and diabetes. Several studies have demonstrated a relationship between blood TCDD levels and hyperinsulinemia. The data suggest that non-diabetic individuals exposed to TCDD have an increased risk of insulin-resistance, being able to maintain normal blood glucose levels but only because of very high concentrations of insulin. As a result of available evidence, public policy decisions have been made, such as a decision by the Veterans Administration that diabetes is a service-connected condition in Agent Orange-exposed Vietnam veterans. Here we study the relation between TCDD insulin sensitivity

    Structural equation modeling (SEM) was used to examine associations among trauma-related contextual factors, initial psychological reactions, social support, and subsequent disclosure on posttraumatic stress disorder (PTSD) symptoms in a sample of World War II (WWII) veterans exposed to mustard gas (N = 305). A structural model suggested that initial psychological reaction mediated the relationship between variables related to the context of mustard gas exposure and severity of PTSD symptoms 50 years later. Unexpectedly, social support appeared to be positively related to PTSD symptoms, and not related to the contextual variables or initial psychological reactions. These findings contribute to our understanding of PTSD in older veterans, and have relevance for early intervention services to prevent PTSD among those at risk for exposure to toxic agents.

  2. Excretion of depleted uranium by Gulf war veterans

    2003-01-01

    During the Persian Gulf War, in 1991, approximately 100 US military personnel had potential intakes of depleted uranium (DU), including shrapnel wounds. In 1993, the US government initiated a follow-up study of 33 Gulf War veterans who had been exposed to DU, many of whom contained embedded fragments of DU shrapnel in their bodies. The veterans underwent medical evaluation, whole-body counting, and urinalysis for uranium by kinetic phosphorescence analysis (KPA). Data are available from seven individuals who exceeded the detection limit for whole-body counting and also had elevated urinary uranium. Urinary excretion rates, in μg U g -1 creatinine, were determined in 1997 and 1999. The body contents, in mg DU, were determined in 1997; it is assumed there were no significant decreases in total body content in the interim. For the 1997 data, the mean fractional excretion was (2.4 ± 2.8) x 10 -5 g -1 creatinine, and for the 1999 data, the mean was (1.1 ± 0.6) x 10 -5 g -1 creatinine. However, these means are not significantly different, nor is there any correlation of excretion rate with body content. Thus, human data available to date do not provide any basis for determining the effects of particle surface area, composition and solubility, and biological processes such as encapsulation, on the excretion rate.

    In-depth interviews with seven atomic veterans and their families indicated powerful psychological effects on all family members from exposure to low-level ionizing radiation. Four themes emerged: the invalidation of their experiences by government and other authority figures; family concerns about genetic effects on future generations; family members' desire to protect each other from fears of physical consequences; and desire to leave a record of their experiences to help prevent future suffering

    The aims of this study were to prepare a Persian version of the temporal resolution test using the method of Phillips et al (1994) and Stuart and Phillips (1996), and to compare the word-recognition performance in the presence of continuous and interrupted noise as well as the temporal resolution abilities between monolingual (ML) Persian and bilingual (BL) Turkish-Persian young adults. Word-recognition scores (WRSs) were obtained in quiet and in the presence of background competing continuous and interrupted noise at signal-to-noise ratios (SNRs) of -20, -10, 0, and 10 dB. Two groups of 33 ML Persian and 36 BL Turkish-Persian volunteers participated. WRSs significantly differed between ML and BL subjects at four sensation levels in the presence of continuous and interrupted noise. However, the difference in the release from masking between ML and BL subjects was not significant at the studied SNRs. BL Turkish-Persian listeners seem to show poorer performance when responding to Persian words in continuous and interrupted noise. However, bilingualism may not affect auditory temporal resolution ability.

    Deployment-related risk factors for suicidal ideation among Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF) veterans have received a great deal of attention. Studies show that mental health symptoms mediate the association between most deployment stressors and suicidal ideation; however, family-related factors during deployment are largely unexplored. We examined posttraumatic stress disorder (PTSD) and depression symptoms as mediators of the associations between deployment family support and stress and post-deployment suicidal ideation in combat-exposed OEF/OIF veterans. National cross-sectional mail survey. 1046 veterans responded to the survey. The sample for this study was 978 veterans who experienced combat. Regression-based path analyses were conducted. Family support and stress had direct associations with suicidal ideation. When PTSD and depression symptoms were examined as mediators of these associations, results revealed significant indirect paths through these symptoms. This study contributes to the literature on suicidal ideation risk factors among OEF/OIF veterans. Deployment family support and family stress are associated with suicidal ideation; however these associations occur primarily through mental health symptomatology, consistent with findings observed for other deployment factors. This research supports ongoing efforts to treat mental health symptomatology as a means of suicide prevention.

    Research on emotional speech often requires valid stimuli for assessing perceived emotion through prosody and lexical content. To date, no comprehensive emotional speech database for Persian is officially available. The present article reports the process of designing, compiling, and evaluating a comprehensive emotional speech database for colloquial Persian. The database contains a set of 90 validated novel Persian sentences classified in five basic emotional categories (anger, disgust, fear, happiness, and sadness), as well as a neutral category. These sentences were validated in two experiments by a group of 1,126 native Persian speakers. The sentences were articulated by two native Persian speakers (one male, one female) in three conditions: (1) congruent (emotional lexical content articulated in a congruent emotional voice), (2) incongruent (neutral sentences articulated in an emotional voice), and (3) baseline (all emotional and neutral sentences articulated in neutral voice). The speech materials comprise about 470 sentences. The validity of the database was evaluated by a group of 34 native speakers in a perception test. Utterances recognized better than five times chance performance (71.4 %) were regarded as valid portrayals of the target emotions. Acoustic analysis of the valid emotional utterances revealed differences in pitch, intensity, and duration, attributes that may help listeners to correctly classify the intended emotion. The database is designed to be used as a reliable material source (for both text and speech) in future cross-cultural or cross-linguistic studies of emotional speech, and it is available for academic research purposes free of charge.

    Full Text Available Persian Dari is a language which has been used not only by the people of Madain and western cities on the coast of Arvand river but also by the people in eastern cities like Balkh and Marv . Nevertheless most of the researchers of Persian language or literature are trying to prove that Dari has been a limited language or a dialect of Persian belonged to some eastern districts of Iran and it has been extended to other parts of Iran by some Samanid governors. This article tries to clarify this subject as far as possible and prove that Dari title has been derived from Sasanid Darbar and has not any relation with eastern governors in third or fourth century.

    To determine a possible effect of low dose radiation on DNA repair processes, peripheral lymphocytes of mine workers exposed to 222 Rn in the thermal gallery of Badgastein (Austria) and employees of the Austrian Research Centre Seibersdorf, exposed to varying doses of gamma radiation, were investigated. The capacity for unscheduled DNA synthesis (UDS) induced by in vitro UV irradiation was measured by autoradiography of isolated lymphocytes of exposed persons and unexposed controls. In all 222 Rn-exposed mine workers a significant increase of UDS above control values could be observed. Gamma irradiation 31 mrad had a significant effect on UDS, indicating a stimulation of DNA repair capability by chronic low dose exposure. (Author)

    Full Text Available Background: To date, with rapid increase of bilingual children, more attention about different patterns of the bilingual children narratives is needed. The aim of this study was to compare microstructure level of narratives generated by typical developing kindergarten children who were bilingual in Persian and Balochi with monolingual Persian speakers. Method: Thirty Persian-speaking monolingual and thirteen available bilingual children (aged 48 months old participated in this study. Children’s story telling was audio-recorded and analyzed using the Persian-NAP (Narrative Assessment Protocol guidelines. Results: All of the NAP indicators include of group structure, phrase structure, modifiers, noun and verbs didn’t show significant difference between monolingual and bilingual children (0.06≤p≤0.5. Conclusion: We didn’t find different performance in the five NAP indicators between bilingual and monolingual children. It may be suggested that the different patterns of creating phrases and sentences in two languages don’t affect the grammatical use of them in second language.

    U.S. combat veterans of the Iraq and Afghanistan wars have elevated rates of posttraumatic stress disorder (PTSD) compared to the general population. Self-compassion, characterized by self-kindness, a sense of common humanity when faced with suffering, and mindful awareness of suffering, is a potentially modifiable factor implicated in the development and maintenance of PTSD. We examined the concurrent and prospective relationship between self-compassion and PTSD symptom severity after accounting for level of combat exposure and baseline PTSD severity in 115 Iraq and Afghanistan war veterans exposed to 1 or more traumatic events during deployment. PTSD symptoms were assessed using the Clinician Administered PTSD Scale for DSM-IV (CAPS-IV) at baseline and 12 months (n =101). Self-compassion and combat exposure were assessed at baseline via self-report. Self-compassion was associated with baseline PTSD symptoms after accounting for combat exposure (β = -.59; p Afghanistan war veterans. Copyright © 2015 Wiley Periodicals, Inc., A Wiley Company.

    Previous mortality studies of U.S. Gulf War veterans through 2000 and 2004 have shown an increased risk of brain cancer mortality among some deployed individuals. When veterans possibly exposed to environmental contaminants associated with demolition of the Khamisiyah Ammunition Storage Facility at Khamisiyah, Iraq, have been compared to contemporaneously deployed unexposed veterans, the results have suggested increased risk for mortality from brain cancer among the exposed. Brain cancer mortality risk in this cohort has not been updated since 2004. This study analyzes the risk for brain cancer mortality between 1991-2011 through two series of comparisons: U.S. Gulf War deployed and non-deployed veterans from the same era; and veterans possibly exposed to environmental contaminants at Khamisiyah compared to contemporaneously deployed but unexposed U.S. Gulf War veterans. Risk of brain cancer mortality was determined using logistic regression. Life test hazard models were created to plot comparisons of annual hazard rates. Joinpoint regression models were applied to assess trends in hazard rates for brain cancer mortality. U.S. Army veterans possibly exposed at Khamisiyah had similar rates of brain cancer mortality compared to those not possibly exposed; however, veterans possibly exposed had a higher risk of brain cancer in the time period immediately following the Gulf War. Results from these analyses suggest that veterans possibly exposed at Khamisiyah experienced different patterns of brain cancer mortality risk compared to the other groups.

    Abstract During the Vietnam War, the US military sprayed almost 20 million gallons of Agent Orange (AO), an herbicide contaminated with dioxin, over Vietnam. Approximately, 2.7 million US military personnel may have been exposed to AO during their deployment. Ordinarily, veterans who can demonstrate a nexus between a diagnosed condition and military service are eligible for Department of Veterans Affairs (VA) service-connected disability compensation. Vietnam Veterans have had difficulty, however, establishing a nexus between AO exposure and certain medical conditions that developed many years after the war. In response, VA has designated certain conditions as “presumed service connected” for Vietnam Veterans who were present and possibly exposed. Veterans with any of these designated conditions do not have to document AO exposure, making it easier for them to access the VA disability system. The extent to which VA healthcare utilization patterns reflect easier access afforded those with diagnosed presumptive conditions remains unknown. In this cross-sectional study, we hypothesized that Vietnam Veterans with diagnosed presumptive conditions would be heavier users of the VA healthcare system than those without these conditions. In our analysis of 85,699 Vietnam Veterans, we used binary and cumulative logit multivariable regression to assess associations between diagnosed presumptive conditions and VA healthcare utilization in 2013. We found that diagnosed presumptive conditions were associated with higher odds of 5+ VHA primary care visits (OR = 2.01, 95% CI: 1.93–2.07), 5+ specialty care visits (OR = 2.11, 95% CI: 2.04–2.18), emergency department use (OR = 1.22, 95% CI: 1.11–1.34), and hospitalization (OR = 1.23, 95% CI: 1.17–1.29). Consistent with legislative intent, presumptive policies appear to facilitate greater VA system utilization for Vietnam Veterans who may have been exposed to AO. PMID:29742706

    The Depleted Uranium Follow-Up Program is a clinical surveillance program run by the Baltimore Veterans Affairs Medical Center since 1993 for veterans of the Gulf and Iraqi wars who were exposed to depleted uranium (DU) as a result of "friendly-fire" incidents. In 2009, 40 veterans from this cohort were screened for skin reactivity to metals by patch-testing with extended metal series and uranyl acetate (0.25%, 2.5%, and 25%). A control arm comprised 46 patients without any known occupational exposures to DU who were seen at the University of Maryland Dermatology Clinic for evaluation of allergic contact dermatitis. Excluding irritant reactions, no patch-test reactions to uranyl acetate were observed in the participants. Irritant reactions to DU were more common in the clinic cohort, likely reflective of the demographic differences between the two arms of the study. Biologic monitoring of urine uranium concentrations in the DU program participants with 24-hour urine samples showed evidence of percutaneous uranium absorption from the skin patches. We conclude that dermatitis observed in a subset of the veterans was unrelated to their military DU exposure. Our data suggest that future studies of skin testing with uranyl acetate should utilize 0.25%, the least irritating concentration.

    The accelerated process of globalization affecting mankind doesn't exclude safety matters. Indeed, some trans national corporations are increasingly offering specialized engineering services such as industrial radiography or well lodging. As well, a growing scientific exchange involves the mobility of nuclear researchers in different areas, for instance radiochemistry, nuclear medicine and radiotherapy. Such a breakdown in the technological frontiers must necessarily be reflected by the regulatory solutions. Particularly, diverse levels of theoretical-practical training for radiation exposed personnel coexist in the Latin-American Region, being an especially sensitive problem for radiation protection matters. The spectrum goes from post-graduate courses required for radiation protection officers in some countries, while in others only basic recommendations are required for the operating personnel. Another scheme consists of medium level course for the operating personnel, while radiation protection officers don't have special requirements. Many educational private institutions teach non standardized courses which only give broad concepts of radiation protection. On the other hand, usually nothing is said about the operational training, or else its certification is entrusted to the employer itself. In some countries multiple Regulatory Authorities apply dissimilar criteria to assess safety matters, including the evaluation of workers applications. The necessary regional integration makes indispensable to establish common standards for granting authorizations. Having similar or homogeneous requirements for the universe of radiation exposed personnel, i.e. source operators, radiation protection officers, qualified experts and technical support people would be easier for the Regulatory Authorities to have common methodologies of evaluation for the applicants. An IAEA supported technical cooperation project related to this paper seeks to establish standardized

    The aims of this study are to assess external radiation exposed doses of body and hands of nuclear medicine workers who handle radiation sources, and to measure radiation exposed doses of the hands induced by a whole body bone scan with high frequency and handling a radioactive sources like 99m Tc-HDP and 18 F-FDG in the PET/CT examination. Skillful workers, who directly dispense and inject from radiation sources, were asked to wear a TLD on the chest and ring finger. Then, radiation exposed dose and duration exposed from daily radiation sources for each section were measured by using a pocket dosimeter for the accumulated external doses and the absorbed dose to the hands. In the survey of four medical institutions in Incheon Metropolitan City, only one of four institutions has a radiation dosimeter for local area like hands. Most of institutions uses radiation shielding devices for the purpose of protecting the body trunk, not local area. Even some institutions were revealed not to use such a shielding device. The exposed doses on the hands of nuclear medicine workers who directly handles radioactive sources were approximately twice as much as those on the body. The radiation exposure level for each section of the whole body bone scan with high frequency and that of the PET/CT examination showed that radiation doses were revealed in decreasing order of synthesis of radioactive medicine and installation to a dispensing container, dispensing, administering and transferring. Furthermore, there were statistically significant differences of radiation exposure doses of the hands before and after wearing a syringe shielder in administration of a radioactive sources. In this study, although it did not reach the permissible effective dose for nuclear medicine, the occupational workers were exposed by relatively higher dose level than the non-occupational workers. Therefore, the workers, who closely exposed to radioactive sources should be in compliance with safety

    Full Text Available Abstract Persian as the second language of the world of Islam is closely related to the teachings of this divine religion, so learning Persian besides Islamic and Shia teachings would be helpful for Islamic scholars. In this regard, Jame’at al-Mostafa al-‘alamiye in the context of the Persian language tries to train Islamic scholars, translators and missioners. Center of language education and Islamic teachings which is the subset of Jame’at al-Mostafa, has formulated a collection of eight books named Persian to Persian teaching which is taught in different centers of Jame’at al-Mostafa inside and outside of the country. High goals of this Shia association represents the importance of authoring and analyzing education books. So their accuracy needs more attention and research. This essay aimed at describing and grammatical analyzing of this educational series. The present study deals with the importance and methods of teaching grammar to non-Persian speakers after introducing the Jame’at al-Mostafa al-‘alamiye; also, besides introducing the required grammatical issues, it describes eight volumes books of teaching Persian-to-Persian grammatically. Then the grammatical difficulties of these books are investigated in ten separate sections with giving some examples. The study ends with providing some strategies to improve the grammatical issues of this educational set and other books of teaching Persian language to non-Persian speakers. In the early years after the Islamic revolution, some foreign students came to Iran to study Islamic studies so the supervisory board of non-Iranian students was established to answer and to organize their educational and livelihood status in 1979. “Jame’at al-Mostafa al-‘alamiye” was founded in Qom and other cities after the continuous changes in 2007. This center tries to grow the Islamic scholar, translator, and missionary by teaching Persian language; in this way, center of language and

    Full Text Available Aiming to study the freshness of Persian information, the study attempted to explore the indexing speed of Persian newspapers in Google, Yahoo and Bing. The present study was conducted using a webometric method. The population study comprised all the online newspapers published in Persian. The study sample was identified using a targeted method. It included those Persian newspapers listed on the Magiran database with their electronic versions regularly published on their respective websites. The results revealed that Google outperforms the two other search engines in terms of timely indexing the Persian newspapers. Furthermore, it generally enjoys a more consistent and stable indexing model. Yahoo and Bing are not only slower in indexing the newspapers, but also experience a comparably lower consistency level in their indexing models. Yahoo and Bing show to be comparable in their indexing speeds. In this study, the indexing status of Persian newspapers on different internet search engines was investigated for the first time. Results showed that those accessing these newspapers using internet search engines will have a higher chance of accessing their most updated versions using Google.

    Full Text Available Culture and identity in a society can be represented in the architecture and the meanings intertwined with it. In this sense, the architecture and design are the interface for transferring meaning and identity to the nation and future generations. Persian gardens have been evolved through the history of Persian Empire in regard to the culture and beliefs of the society. This paper aims to investigate the patterns of design and architecture in Persian gardens and the meanings intertwined with their patterns and significant elements such as water and trees. Persian gardens are not only about geometries and shapes; but also manifest different design elements, each representing a specific symbol and its significance among the society. This paper seeks to explore Persian gardens in terms of their geometric structure, irrigation system, network construction and pavilions alongside design qualities such as hierarchy, symmetry, centrality, rhythm and harmony. In the second stage, the paper investigates the fundamental symbols and their philosophy in the creation of Persian gardens and in relation to the architecture and design.

    The long-term effects of herbicide exposure on human health are not fully known and remain controversial. Herbicides were used by US forces for defoliation and crop destruction during the Vietnam War. The toxic effects of 2,3,7,8-tetrachlorodibenzo-p-dioxin (dioxin), the contaminant found in Agent Orange and other herbicides sprayed during the war, continue to be of concern more than thirty years after the war. Studies of the post-service mortality experience of Vietnam veterans have given mixed results. The US Army Chemical Corps Study1 reported an increased risk of death due to digestive diseases and a non-significant increase in the risk of death from cancer. A study of Australian Army veterans reported an increased risk of death due to digestive diseases but no increases due to cancer. However, a study of women veterans3 found an increased risk of death due to pancreatic cancer and a study of Vietnam veterans from Michigan6 reported an excess of deaths due to non-Hodgkin's lymphoma. The Air Force Health Study is a prospective epidemiological study of the health, mortality and reproductive outcomes of veterans of Operation Ranch Hand, the unit responsible for aerially spraying herbicides in Vietnam from 1962 to 1971. The study, now in its 22{sup nd} year, began in 1982 and will conclude in 2006. Here we update our second report by summarizing current all-cause and cause-specific post-service mortality in veterans of Operation Ranch Hand.

    Genotoxicity and DNA damage endpoints are used to evaluate results in the context of cell survival. Genotoxicity in mammalian cells is monitored mostly by using cytokinesis-block micronucleus (CBMN) assay. The score of micronuclei (MN) in peripheral blood lymphocytes can be used as a biomarker and also as a bio-dosimeter of radiation exposure. In the present study the effect of natural radiation on albino rats has been investigated, to find out if there is any increase in MN frequency in peripheral blood lymphocytes. Animals at the age of 2-3 weeks were exposed to natural radiation, at the dose of 10.38 μGyh -1 for a period of 6 months. A parallel control set was also maintained (0.12 μGy h -1 '). Blood samples were collected from both test (exposed to natural radiation) and control rats. Lymphocyte culture was done following 'microculture techniques' for 72 h. Cytochalasin B, at a concentration of 6.0 μg/ml, was added to the lymphocyte cultures at 44 h to block cytokinesis. The frequency of MN was evaluated by scoring a total of 1000 binucleated (BN) cells from one slide. The frequency of MN among the rats exposed to natural radiation was found to be 1.83±0.05 per 1000 BN cells and in the control it was 1.82±0.07 per 1000 BN cells. No statistically significant difference in the MN frequencies of exposed and control groups (p>0.05) was seen. The lower MN frequency in natural radiation exposed rats could be an indication of adaptive response. (author)

  15. Occupational health care of radiation exposed workers

    1995-01-01

    The medical problems encountered by the earlier pioneer workers in radiation at the turn of the century are well known. In the 1928, the ICRP (International Committee for Radiological Protection) was instituted and the ALARA principle of radiation protection was evolved. Occupational health care is about maintaining the health and safety of workers in their workplaces. This involves using medical, nursing and engineering practices to achieve its objectives. In certain occupations, including those where workers are exposed to ionising radiation, some of these principles are enshrined in the legislation and would require statutory compliance. Occupational health care of radiation workers seek to prevent ill health arising from exposure to radiation by consolidating the benefits of exposures control and dosimetry. This is via health surveillance for spillages, contamination and exposures to unsealed sources of radiation. It is unlikely that can plan and hope to cater for a Chernobyl type of disaster. However, for the multitude of workers in industry exposed to radiation, control models are available. These are from the more in industrialize countries with a nuclear based energy industry, and where radioactive gadgetry are used in places ranging from factories and farms to construction sites. These models involve statutory requirements on the standard of work practices, assessment of fitness to work and the monitoring of both the worker and the workplace. A similar framework of activity is present in Malaysia. This will be further enhanced with the development of her general health and safety at work legislation. (author)

  16. Studies of workers exposed to low doses of external radiation

    Gilbert, E.S.

    1991-04-01

    Currently, several epidemiologic studies of workers who have been exposed occupationally to low levels of radiation are being conducted, and include studies of workers in the United States, Great Britain, and Canada involved in the production of both defense materials and nuclear power. This paper focuses on studies that evaluate the possible adverse effects resulting from external exposure to radiation. The radiation risk estimates that have been used to establish radiation protection standards for workers and others have been obtained mainly from studies of persons exposed at high doses and dose rates. However, questions remain with regard to the extrapolation process that has been necessary for estimating low-level radiation risks. Occupational studies provide a direct assessment of risk based on data on persons exposed at the actual levels of interest. If current risk estimates are correct, these studies have very little chance of detecting risk, but can still be used to provide useful upper limits on risks. The studies are also adequate to detect serious underestimation of risks. 36 refs., 3 figs., 3 tabs

    This study aimed to determine the factor structure of the spiritual well-being among a sample of the Iranian veterans. In this methodological research, 211 male veterans of Iran-Iraq warfare completed the Paloutzian and Ellison spiritual well-being scale. Maximum likelihood (ML) with oblique rotation was used to assess domain structure of the spiritual well-being. The construct validity of the scale was assessed using confirmatory factor analysis (CFA), convergent validity, and discriminant validity. Reliability was evaluated with Cronbach's alpha, Theta (θ), and McDonald Omega (Ω) coefficients, intra-class correlation coefficient (ICC), and construct reliability (CR). Results of ML and CFA suggested three factors which were labeled "relationship with God," "belief in fate and destiny," and "life optimism." The ICC, coefficients of the internal consistency, and CR were >.7 for the factors of the scale. Convergent validity and discriminant validity did not fulfill the requirements. The Persian version of spiritual well-being scale demonstrated suitable validity and reliability among the veterans of Iran-Iraq warfare.

    The incidence of micronuclei was evaluated to assess the induction of an adaptive response to non-ionizing radiofrequency (RF) radiation in peripheral blood lymphocytes collected from five different human volunteers. After stimulation with phytohemagglutinin for 24 h, the cells were exposed to an adaptive dose of 900 MHz RF radiation used for mobile communications (at a peak specific absorption rate of 10 W/kg) for 20 h and then challenged with a single genotoxic dose of mitomycin C (100 ng/ml) at 48 h. Lymphocytes were collected at 72 h to examine the frequency of micronuclei in cytokinesis-blocked binucleated cells. Cells collected from four donors exhibited the induction of adaptive response (i.e., responders). Lymphocytes that were pre-exposed to 900 MHz RF radiation had a significantly decreased incidence of micronuclei induced by the challenge dose of mitomycin C compared to those that were not pre-exposed to 900 MHz RF radiation. These preliminary results suggested that the adaptive response can be induced in cells exposed to non-ionizing radiation. A similar phenomenon has been reported in cells as well as in animals exposed to ionizing radiation in several earlier studies. However, induction of adaptive response was not observed in the remaining donor (i.e., non-responder). The incidence of micronuclei induced by the challenge dose of mitomycin C was not significantly different between the cells that were pre-exposed and unexposed to 900 MHz RF radiation. Thus the overall data indicated the existence of heterogeneity in the induction of an adaptive response between individuals exposed to RF radiation and showed that the less time-consuming micronucleus assay can be used to determine whether an individual is a responder or non-responder.

    Methylation of the SKA2 gene has recently been identified as a promising biomarker of suicide risk. Based on this finding, we examined associations between SKA2 methylation, cortical thickness, and psychiatric phenotypes linked to suicide in trauma-exposed veterans. 200 trauma-exposed white non-Hispanic veterans of the recent conflicts in Iraq and Afghanistan (91% male) underwent clinical assessment and had blood drawn for genotyping and methylation analysis. 145 participants also had neuroimaging data available. Based on previous research, we examined DNA methylation at the CpG locus cg13989295 as well as DNA methylation adjusted for genotype at the methylation-associated SNP (rs7208505) in relationship to whole-brain cortical thickness, posttraumatic stress disorder symptoms (PTSD), and depression symptoms. Whole-brain vertex-wise analyses identified three clusters in prefrontal cortex that were associated with genotype-adjusted SKA2 DNA methylation (methylationadj). Specifically, DNA methylationadj was associated with bilateral reductions of cortical thickness in frontal pole and superior frontal gyrus, and similar effects were found in the right orbitofrontal cortex and right inferior frontal gyrus. PTSD symptom severity was positively correlated with SKA2 DNA methylationadj and negatively correlated with cortical thickness in these regions. Mediation analyses showed a significant indirect effect of PTSD on cortical thickness via SKA2 methylation status. Results suggest that DNA methylationadj of SKA2 in blood indexes stress-related psychiatric phenotypes and neurobiology, pointing to its potential value as a biomarker of stress exposure and susceptibility.

    The Persian cat is mainly characterized by an extremely brachycephalic face as part of the standard body conformation. Despite the popularity, world-wide distribution, and economic importance of the Persian cat as a fancy breed, little is known about the genetics of their hallmark morphology, brachycephaly. Over 800 cats from different breeds including Persian, non-Persian breeds (Abyssinian, Cornish Rex, Bengal, La Perm, Norwegian Forest, Maine Coon, Manx, Oriental, and Siamese), and Persian-derived breeds (British Shorthair, Scottish Fold, Selkirk Rex) were genotyped with the Illumina 63 K feline DNA array. The experimental strategy was composed of three main steps: (i) the Persian dataset was screened for runs of homozygosity to find and select highly homozygous regions; (ii) selected Persian homozygous regions were evaluated for the difference of homozygosity between Persians and those considered non-Persian breeds, and, (iii) the Persian homozygous regions most divergent from the non-Persian breeds were investigated by haplotype analysis in the Persian-derived breeds. Four regions with high homozygosity (H > 0.7) were detected, each with an average length of 1 Mb. Three regions can be considered unique to the Persian breed, with a less conservative haplotype pattern in the Persian-derived breeds. Moreover, two genes, CHL1 and CNTN6 known to determine face shape modification in humans, reside in one of the identified regions and therefore are positional candidates for the brachycephalic face in Persians. In total, the homozygous regions contained several neuronal genes that could be involved in the Persian cat behavior and can provide new insights into cat domestication.

    Full text: Serbia and Montenegro legislation concerning with radiation protection was upgrading after publication ICRP- 60 and B.S.S., No.115. Present Law on the Protection against Ionizing Radiation is in force from 1996. Among quite new issues in radiation protection regulations there was article relate to obligatory refresher training. Due to adverse political and economic situation through many years radiation protection regulations were not fulfill completely. The aim of this investigation was to get real view to education level of professional exposed workers. In Serbia and Montenegro the most of ionizing radiation sources are in medical use and the most exposed workers are radiographers and radiologists. The test was passed by 200 radiographers and 50 radiologists. Main groups of questions were: Radiation protection and safety; difference between safety and security; legislation: law and regulations; incidents, accidents and operational failures: recording, learning. Usually, knowledge from school pales. New quantities (as ambient and personal dose equivalent) are mostly unknown. It is easier to understand the real difference between safety and security than to understand linguistic differences. Discussing regulations workers are more interesting in syndicate regulations than radiation protection ones. Operational failures and incidents are hidden. Better to say: nobody dare to speak about them. The results imposed conclusion that regulatory body has to pay more attention to upraise safety culture and radiation protection education level of professional exposed workers. (authors)

  3. Impact of presumed service-connected diagnosis on the Department of Veterans Affairs healthcare utilization patterns of Vietnam-Theater Veterans: A cross-sectional study.

    During the Vietnam War, the US military sprayed almost 20 million gallons of Agent Orange (AO), an herbicide contaminated with dioxin, over Vietnam. Approximately, 2.7 million US military personnel may have been exposed to AO during their deployment. Ordinarily, veterans who can demonstrate a nexus between a diagnosed condition and military service are eligible for Department of Veterans Affairs (VA) service-connected disability compensation. Vietnam Veterans have had difficulty, however, establishing a nexus between AO exposure and certain medical conditions that developed many years after the war. In response, VA has designated certain conditions as "presumed service connected" for Vietnam Veterans who were present and possibly exposed. Veterans with any of these designated conditions do not have to document AO exposure, making it easier for them to access the VA disability system. The extent to which VA healthcare utilization patterns reflect easier access afforded those with diagnosed presumptive conditions remains unknown. In this cross-sectional study, we hypothesized that Vietnam Veterans with diagnosed presumptive conditions would be heavier users of the VA healthcare system than those without these conditions. In our analysis of 85,699 Vietnam Veterans, we used binary and cumulative logit multivariable regression to assess associations between diagnosed presumptive conditions and VA healthcare utilization in 2013. We found that diagnosed presumptive conditions were associated with higher odds of 5+ VHA primary care visits (OR = 2.01, 95% CI: 1.93-2.07), 5+ specialty care visits (OR = 2.11, 95% CI: 2.04-2.18), emergency department use (OR = 1.22, 95% CI: 1.11-1.34), and hospitalization (OR = 1.23, 95% CI: 1.17-1.29). Consistent with legislative intent, presumptive policies appear to facilitate greater VA system utilization for Vietnam Veterans who may have been exposed to AO.

    Occupational exposure is particularly delicate because of chronic exposure to low doses of ionizing radiation and its cumulative effect, where it is important to consider the biological response of body to given conditions of exposure. The objective of this study was the observation of the recovery of the DNA damages in subjects working in the radiation area in two different intervals.Group I, consisting of 30 subjects, was exposed to ionizing radiation and unstable chromosomal aberrations were identified. Group II included the same, re-examined subjects (30) 9 months later. It was verified that 5 (16.67%) subjects still had unstable chromosomal aberrations, although they had been excluded from radiation area Controls groups (C) consisted of 64 subjects that were not exposed to mutagenic agents.The comparison of the control group with the two studied groups revealed the reduction of the unstable aberrations (p<0.05). The total effective doses, which increased with the years spent in radiation area, reflected the yield of chromosomal aberrations. The presence of chromosomal aberrations in some subjects, after the exclusion from the ionising radiation exposure, suggests that the time needed for the recovery of the DNA damages is different, which indicates the individual differences in radiosensitivity as well as different of the reparatory cellular response.

    Full Text Available Background: During the past two decades, a great deal of research has been conducted on developing affective norms for words in various languages, showing that there is an urgent need to create such norms in Persian language, too. The present study intended to develop a set of 362 Persian words rated according to their emotional valence, arousal, imageability, and familiarity so as to prepare the ground for further research on emotional word processing. This was the first attempt to set affective norms for Persian words in the realm of emotion.  Methods: Prior to the study, a multitude of words were selected from Persian dictionary and academic books in Persian literature. Secondly, three independent proficient experts in the Persian literature were asked to extract the suitable words from the list and to choose the best (defined as grammatically correct and most often used. The database normalization process was based on the ratings by a total of 88 participants using a 9-point Likert scale. Each participant evaluated about 120 words on four different scales.  Results: There were significant relationships between affective dimensions and some psycholinguistic variables. Also, further analyses were carried out to investigate the possible relationship between different features of valences (positive, negative, and neutral and other variables included in the dataset.  Conclusion: These affective norms for Persian words create a useful and valid dataset which will provide researchers with applying standard verbal materials as well as materials applied in other languages, e.g. English, German, French, Spanish, Portuguese, Dutch, etc.

    United States military personnel reported various symptoms after deployment to the Persian Gulf during the 1991 Gulf War. However, the symptoms' long-term prevalence and association with deployment remain controversial. To assess and compare the prevalence of selected medical conditions in a national cohort of deployed and nondeployed Gulf War veterans who were evaluated by direct medical and teledermatologic examinations. A cross-sectional prevalence study performed 10 years after the 1991 Gulf War. Veterans were examined at 1 of 16 Veterans Affairs medical centers. Deployed (n = 1061) and nondeployed (n = 1128) veterans of the 1991 Gulf War. Primary outcome measures included fibromyalgia, the chronic fatigue syndrome, dermatologic conditions, dyspepsia, physical health-related quality of life (Short Form-36 [SF-36]), hypertension, obstructive lung disease, arthralgias, and peripheral neuropathy. Of 12 conditions, only 4 conditions were more prevalent among deployed than nondeployed veterans: fibromyalgia (deployed, 2.0%; nondeployed, 1.2%; odds ratio, 2.32 [95% CI, 1.02 to 5.27]); the chronic fatigue syndrome (deployed, 1.6%; nondeployed 0.1%; odds ratio, 40.6 [CI, 10.2 to 161]); dermatologic conditions (deployed, 34.6%; nondeployed, 26.8%; odds ratio, 1.38 [CI, 1.06 to 1.80]), and dyspepsia (deployed, 9.1%; nondeployed, 6.0%; odds ratio, 1.87 [CI, 1.16 to 2.99]). The mean physical component summary score of the SF-36 for deployed and nondeployed veterans was 49.3 and 50.8, respectively. Relatively low participation rates introduce potential participation bias, and deployment-related illnesses that resolved before the research examination could not, by design, be detected. Ten years after the Gulf War, the physical health of deployed and nondeployed veterans is similar. However, Gulf War deployment is associated with an increased risk for fibromyalgia, the chronic fatigue syndrome, skin conditions, dyspepsia, and a clinically insignificant decrease in the SF-36

    We studied the effect of in vitro life span in normal human fibroblasts exposed to chronically low-dose radiation in heavy-ion radiation field. Cells were cultured in a CO 2 incubator, which was set in the irradiation room for biological study of heavy ions in the Heavy Ion Medical Accelerator in Chiba (HIMAC) at National Institute of Radiological Sciences (NIRS), and exposed to scattered radiations produced with heavy-ion beams throughout the life span of the cell population. Absorbed dose, which was measured using a thermoluminescence dosimeter(TLD) and a Si-semiconductor detector, was to be 1.4 mGy per day when operating the HIMAC machine for biological experiments. The total population doubling number of the exposed cells reduced to 79-93% of non-exposed control cells in the three independent experiments. There is evidence that the exposure of chronically low-dose radiation in heavy-ion radiation field promotes the life-span reduction in cellular level. (author)

    Full Text Available Background and Aim: Speech and language pathologists (SLP often refer to phonological data as part of their assessment protocols in evaluating the communication skills of children. The aim of this study was to develop the Persian version of the phonological test in evaluating and diagnosing communication skills in Persian speaking children and to evaluate its validity and reliability.Methods: The Persian phonological test (PPT was conducted on 387 monolingual Persian speaking boys and girls (3-6 years of age who were selected from 12 nurseries in the northwest region of Tehran. Content validity ratio (CVR and content validity index (CVI were assessed by speechtherapists and linguists. Correlation between speech and language pathologists experts' opinions and Persian phonological test results in children with and without phonological disorders was evaluated to investigate the Persian phonological test validity. In addition, the Persian phonological test test-retest reliability was investigated.Results: Both content validity ratio and content validity index were found to be acceptable (CVR≥94.71 and CVI=97.35. The PPT validity was confirmed by finding a good correlation between s peech and language pathologists experts' opinions and Persian phonological test results ( r Kappa =0.73 and r Spearman =0.76. The percent of agreement between transcription and analyzing error patterns in test-retest (ranging from 86.27%-100% and score-rescore (ranging from 94.28%-100% showed that Persian phonological test had a very high reliability.Conclusion: The results of this study show that the Persian phonological test seems to be a suitable tool in evaluating phonological skills of Persian speaking children in clinical settings and research projects.

    Full Text Available  Abstract Pen-name (Takhalloss is one of the main features of Persian poetry. It has been a matter of concern among many of Persian language geography poets in the orient at least up to the Mashrouteh era. Pen-name has been promoted among the other Muslim nations throuph Persian poetry. Although it is not as famous in the Arab nations as in the Persian speaking nations, it is known as “Alqab-o-shoara” among the Arab nations and, through this way, it has affected the poetrical wealth of the Arabic poets.   The Present paper, using description-analystic approach, compares the pen-names of Persian and Arabic poets under the title of “pen-names” and investigates their features in both cultures. The main research question is: What are the similarities and differences of poetic-names, in Persian and Arabic poets in terms of the type of name, position and importance? The results showed that Pseudonym by its amazing expansion in Persian poetry has also influenced Arabic poetry. In addition to the factors affecting in the choice of pen-names (like pseudonym, pen-name, nickname..., sometimes such external factors as events, commends, community benefactors and climate, as well as internal factors including the poets’ inner beliefs are associated too. .

    The increasing use of ionizing radiation in the medical field as well as in industry and research grants has special importance to the security aspects related to the individual as well as his surroundings, reason for which the implementation of effective Occupational Radiation Protection Programmes constitutes a priority. Presently, in Guatemala, an Occupational Medicine Programme, directed to the Radiosanitary watch over of occupationally exposed personnel does not exist. It is the goal in this project to organize and establish such programme, based on protective and training actions focused toward the employee as the main entity, his specific activities and his work surroundings. Medical watch over together with Radiation Protection will permit the reduction of the occurrence probability of accidents or incidents, as well as the limitation of stochastic effects to the undermost values. The application scope of the present project is, in the first place, directed to the occupationally exposed personnel of the Direcci[n General de Energ[a Nuclear, as regulatory entity of these activities, and afterwards, its application in the different institutions which work with ionizing radiations. All the previously exposed is based on the Nuclear Legislation prevailing in Guatemala as well as the recommendations of international organizations. (author)

    2001-01-01

    Knowledge accumulated till the end of the 20th century is mentioned briefly. More attention is paid to recent findings. Recent studies of uranium contamination of the Persian Gulf and Balkan War veterans have been conducted in the U.S. and Canada by studying distribution of isotopes of DU in the veterans of the NATO and Allied forces who were accidentally contaminated with DU either in the form of imbedded shrapnel or inhalation of uranium contaminating dust. The studies of the U.S. armed forces Research Institute in Bethesda Maryland on the shrapnel wounded veteran's demonstrated increased concentration of the isotopes of DU in the urine eight years after the Persian Gulf War. In contrast non-governmental uranium research groups such as Uranium Medical Centre reported increased urinary excretion of four isotopes of DU in the Allied forces veterans exposed to DU containing dust ten years after the exposure. These studies were confirmed by two methods. Neutron activation analysis confirmed presence of DU in the urine of seven Persian Gulf veterans with ratios significantly different from the natural uranium and in the range of DU, ten years after exposure from inhalation. The veterans of the Allied forces contaminated by inhalation in the Persian Gulf War were also analyzed for the uranium presence for their body fluids, tissues and urine by the method of mass spectrometry. These results presented at the International Conferences in Dublin Ireland, Paris France and New York U.S.A. indicate significant presence of four uranium isotopes in over 60% of contaminated veterans being in the range of DU. The ratio of the uranium isotopes 235/238 is in the range of DU if higher than 137.8. It was found to be in the DU ratio 62% examined by the mass spectrometry analysis. Isotopic composition of natural enriched and DU should be for U 238 /99.3, U 235 /0.7 and U 234 /0.006 and for enriched uranium 99.01, 2.96 and 0.03, while for DU respective ratios are 99.75, 0.25 and 0

    There are many false assumptions regarding influence of radiation on pregnant patients and fetus during diagnostic procedures in spite of scientific facts based on studies (both in general population and among physicians). These false assumptions are mostly based on the idea that every diagnostic procedure that uses ionizing radiation is a cause for serious concern and consideration for artificial abortion as a possible solution. We have analysed the data of counselling of pregnant patients exposed to ionizing radiation during diagnostic procedures in University Hospital Merkur, during a period of four years. In this period we had 26 patients come in counselling due to exposure to ionizing radiation during pregnancy. Results show that most of these patients have been exposed to radiation between 2nd and 3rd week of gestation (36 %), between 4th and 5th week - 32 %; before 2nd week - 24%; and after 6th week of gestation less than 8 %. Average doses were: up to 0.01 cGy in 46.2 % patients; 0.01 - 0.15 cGy in 19.2 % patients; 0.2 - 1 cGy in 26.9 % and 1 cGy or more in 7.7 % of patients. No one of the counselled patients had a medical indication for abortion, even though in a small percentage of patients abortion was a personal subjective decision. Considering that there are no Croatian guidelines for counselling patients exposed to ionizing radiation during pregnancy, recommendation is to use International Commission on Radiological Protection (ICRP) guidelines for management of pregnant patients exposed to ionizing radiation.(author)

    By legal determination, workers exposed to ionizing radiation should use individual dosimeters in the most exposed region of the body, designed to estimate the effective dose, as well as radiation protective clothing to minimize occupational exposures. Regarding dosimetry, in most cases it is perceived that the monthly values of exposure are within the limits of normality, however, even being below the limit can not rule out the possibility of damage that the low dose of ionizing radiation can cause. The objective of this article is to highlight the main chemical effects caused by exposure to ionizing radiation, especially biochemical damage in DNA, chromosomal aberrations and the correlation with the exposure of occupationally exposed individuals, as well as individuals from the public. A bibliographic search was carried out in indexed databases from February to April 2017 with the following descriptors: Radiation Ionizing, DNA Damage and Occupational Exposure. In the 'Science Direct' database were found 1205 articles, in the 'Scopus' 19 articles, in the 'Web of Science' 83 articles, in the 'PubMed' 22 articles and in the 'VHL' 60 articles related to the theme. It was concluded that exposure to ionizing radiation can affect the DNA molecule despite its repair mechanisms, which may result in genotoxicity. It has been reported a correlation between occupationally exposed individuals and chromosomal aberrations, demonstrating that even low doses of ionizing radiation can compromise the genetic material integrity of exposed workers, leading to the need for a periodic cytogenetic study for this group of workers

    2009-11-01

    Full Text Available Persian master builders had introduced an architectural innovation which had an imperishable effect on dome architecture in the Middle East and Central Asia: surmounting a dome on squinches. This paper aims to provide a broader perspective of Persian domes as the most significant feature of Eastern domes in the Middle East. As opposed to previous general historic studies, this paper introduces a new analytical approach directed towards analysis of architectural concepts and stylistic attributes of Persian domes based on an epistemological premise of their space syntax. By analytic reviewing of examples, the paper addresses the origin of Persian domes, their formal morphological constitutions, and their typological forms based on the diversity of the external shell over the specific timeline, from the pre-Islamic era through the Qajar period in Iran. The study of the Persian dome’s characteristics can illustrate undiscovered information about the essences of developing dome constructions in the Middle East. It can also establish new design standards regarding the frameworks of domical building configurations to be used for creating typological diversity in dome design and to renew the morphological principles of the traditional dome compositions in contemporary architectural designs. Finally, the insights gained can inform conservation efforts on domical structures in the region and elsewhere.

    Comprehensive explanation about milk oversupply is not available in the current literature because few studies have been done on this topic. In traditional Persian medicine, milk oversupply and its management have been described. The aim of this study was to investigate milk oversupply from the perspective of medieval Persian practitioners. In this study, some main medical resources of traditional Persian medicine such as Al-Havi and the Canon of Medicine were studied to extract valuable information about milk oversupply. Etiology of milk overproduction according to traditional Persian medicine is based on humors theory and cannot be easily compared with current medical concepts. Diet modifications and natural remedies have been applied for managing this condition but the majority of traditional Persian medicine interventions for reducing milk oversupply have not been scientifically investigated in modern medicine. The knowledge of milk oversupply in traditional Persian medicine may be helpful to conduct further related studies.

    The mortality rates of British radiologists in dependence of the duration of their radiation work are compared with the general mortality rate in England and Wales, the mortality rates of men of the social class 1 and the mortality rates of practicing physicians. It turns out that the mortality by malignant diseases (leukemia and cancer) of persons exposed to radiation at work in nuclear plants is not considerably higher than it is for comparable groups of persons not exposed to radiation. Tumour entities of the GI tract have not been found either in the British radiologists exposed to radiation. (DG) [de

    To determine whether the prevalence of physical comorbidities in Australian Vietnam War veterans with post-traumatic stress disorder (PTSD) is higher than in trauma-exposed veterans without PTSD. Cross-sectional analysis of the health status (based on self-reported and objective clinical assessments) of 298 Australian Vietnam War veterans enrolled by the Gallipoli Medical Research Institute (Brisbane) during February 2014 - July 2015, of whom 108 were confirmed as having had PTSD and 106 served as trauma-exposed control participants.Main outcomes and measures: Diagnostic psychiatric interview and psychological assessments determined PTSD status, trauma exposure, and comorbid psychological symptoms. Demographic data, and medical and sleep history were collected; comprehensive clinical examination, electrocardiography, spirometry, liver transient elastography, and selected pathology assessments and diagnostic imaging were performed. Outcomes associated with PTSD were identified; regression analysis excluded the effects of potentially confounding demographic and risk factors and comorbid symptoms of depression and anxiety. The mean total number of comorbidities was higher among those with PTSD (17.7; SD, 6.1) than in trauma-exposed controls (14.1; SD, 5.2; P Vietnam veterans is associated with comorbidities in several organ systems, independent of trauma exposure. A comprehensive approach to the health care of veterans with PTSD is needed.

  1. Persian Words Used in Kazi Nazrul Islam's Poetry

    Full Text Available Kazi Nazrul Islam, the national poet of Bangladesh, popularly known as Nazrul-the rebel poet, is undoubtedly one who may rightly be called as one of the greatest “poets of people” of the world. He was the first poet in Bengali literature that used extensive Arabic and Persian words to express his views and to create a Muslim renaissance within the whole Bengali nation. He was a multi-lingual poet. That’s why we see huge Arabic, Persian, Hindi, Sanskrit and Urdu words, even sentences in almost everywhere of his literature. This article is about the Persian words that Nazrul had used in his poetry. Though the majority of his poems consists of more or less Persian words, in this article, we discussed five of his poems named Shat-il-Arab, Moharram, Kamal Pasha, Qorbani and the 12th Fateha that has most Persian words comparatively.

    To estimate the cumulative incidence of sexual assault during the time of Gulf War I among male Gulf War I Veterans who later applied for Department of Veterans Affairs (VA) post-traumatic stress disorder disability benefits and to identify potential risk and protective factors for sexual assault within the population. Mailed, national, cross-sectional survey supplemented with VA administrative and clinical data. Of 2,415 Veterans sampled, 1,700 (70%) responded. After adjusting for nonignorable missing data, the cumulative incidence of sexual assault during Gulf War I in this population ranged from 18% [95% confidence intervals (CI): 5.0%-51.9%] to 21% (95% CI: 20.0-22.0). Deployment was not associated with sexual assault [Odds Ratio (OR), 0.96; 95% CI: 0.75-1.23], but combat exposure was (OR, 1.80; 95% CI: 1.52-2.10). Other correlates of sexual assault within the population included working in a unit with greater tolerance of sexual harassment (OR, 1.80; 95% CI: 1.52-2.10) and being exposed to more sexual identity challenges (OR, 1.76; 95% CI: 1.55-2.00). The 9-month cumulative incidence of sexual assault in this particular population exceeded the lifetime cumulative incidence of sexual assault in U.S. civilian women. Although Persian Gulf deployment was not associated with sexual assault in this population, combat exposure was. Reprint & Copyright © 2014 Association of Military Surgeons of the U.S.

    Full Text Available Biotransformation enzymes of xenobiotics (ethoxyresorufin-O-deethylase, cytochrome P4501A1 content and glutathione-S-transferase were investigated in the liver of Persian Sturgeon (Acipenser persicus after a 96-hour exposure to polycyclic aromatic hydrocarbons (PAHs, premutagenic benzo[a]pyrene (BaP and beta-naphthoflavone (BNF. The fish were injected 10 mg/kg wet-body weight in corn oil for 96 hours every days. Ethoxyresorufin-O-deethylase activity (EROD and glutathione s-transferase activity (GST were measured in the fish liver. Cytochrome P4501A1 (CYP1A1 content was estimated by indirect enzyme-linked immunosorbent assay (ELISA. The response appeared as early as 12 hours post exposure. A time-dependent response was observed in the EROD activity, being significantly higher at 48 hours post exposure to 10 mg/kg of BaP. The greatest induction occurred in the fish treated with 10 mg/kg BaP, in which a 32.1- fold increase in EROD activity was observed. Results showed that EROD activity in A. persicus is significantly increased by BaP and BNF treatments. Both chemicals showed higher values of EROD activity compared to the liver CYP1A content. There was a rise in glutathione-S-transferase activity in fish exposed to BNF, but no increase was observed in fish treated with BaP. The results showed that hepatic CYP1A expression in terms of induction of EROD activity might be suited as a biomarker of organic contamination in aquatic environments and led to lower sensitivity of the second phase in the detoxification enzyme.

    The aim of this investigation was to analyse the results of a four year follow- up study of chromosome aberrations in a population occupationally exposed to microwave radiation. The study included a group of 30 healthy volunteers - radar technicians occupationally exposed to microwave radiation and a group of 30 healthy controls from the general population. The average duration of employment of the exposed subjects was 16 years. The chromosome aberrations assay was carried out on 48 h culture of lymphocytes. Microwave power density was measured with Raham model 4A (General Microwave Corporation, Farmingdale, NY) at different workplaces. The measurements of electromagnetic field power density distribution at different workplaces show that during an ordinary workday the examinees stay in zones with power density below 5 mW/cm 2 with a frequency range of 1250-1350 MHz. The chromosomal type of aberrations in the exposed group during the 4-year follow up study was predominantly higher than in the control group. The total percentage of chromosome aberrations for the exposed group in the first year of the study was 2.36%, in the second 1.43%, in the third 2.88%, and in the fourth year 2.60%, while for the control group was 1.39%. In every year of investigation in exposed group manifested dicentric chromosomes, while in last two years ring chromosome also detected. Mutagenic changes in the somatic cells detected in exposed subjects pointed to the fact that these cellular damages can be related to continuous occupational exposure to microwave radiation.

    Full Text Available  Abstract Persian as the second language of the world of Islam is closely related to the teachings of this divine religion, so learning Persian besides Islamic and Shia teachings would be helpful for Islamic scholars. In this regard, Jame’at al-Mostafa al-‘alamiye in the context of the Persian language tries to train Islamic scholars, translators and missioners. Center of language education and Islamic teachings which is the subset of Jame’at al-Mostafa, has formulated a collection of eight books named Persian to Persian teaching which is taught in different centers of Jame’at al-Mostafa inside and outside of the country. High goals of this Shia association represents the importance of authoring and analyzing education books. So their accuracy needs more attention and research. This essay aimed at describing and grammatical analyzing of this educational series. The present study deals with the importance and methods of teaching grammar to non-Persian speakers after introducing the Jame’at al-Mostafa al-‘alamiye; also, besides introducing the required grammatical issues, it describes eight volumes books of teaching Persian-to-Persian grammatically. Then the grammatical difficulties of these books are investigated in ten separate sections with giving some examples. The study ends with providing some strategies to improve the grammatical issues of this educational set and other books of teaching Persian language to non-Persian speakers. In the early years after the Islamic revolution, some foreign students came to Iran to study Islamic studies so the supervisory board of non-Iranian students was established to answer and to organize their educational and livelihood status in 1979. “Jame’at al-Mostafa al-‘alamiye” was founded in Qom and other cities after the continuous changes in 2007. This center tries to grow the Islamic scholar, translator, and missionary by teaching Persian

    In Iran, a large group of patients are elderly people and they intend to have natural remedies as treatment. These remedies are rooted in historical of Persian and humoral medicine with a backbone of more than 1000 years. The current study was conducted to draw together medieval pharmacological information related to geriatric medicine from some of the most often manuscripts of traditional Persian medicine. Moreover, we investigated the efficacy of medicinal plants through a search of the PubMed, Scopus and Google Scholar databases. In the medieval Persian documents, digestible and a small amount of food such as chicken broth, honey, fig and plum at frequent intervals as well as body massage and morning unctioning are highly recommended. In the field of pharmacotherapy, 35 herbs related to 25 families were identified. Plants were classified as tonic, anti-aging, appetizer, memory and mood enhancer, topical analgesic and laxative as well as health improvement agents. Other than historical elucidation, this paper presents medical and pharmacological approaches that medieval Persian practitioners applied to deal with geriatric complications. PMID:24381461

    In this study, mitochondrial DNA analysis using 16S ribosomal DNA (rDNA) was performed to investigate the phylogeny relationship of Trichiurus lepturus in the Persian Gulf compared to the other investigated area. The amplification of 16S rDNA resulted in a product of 600 bp in all samples. The results showed that the isolated strain belongs to T. lepturus showing 42 divergence sites among the same reported partial sequences of 16S rRNA gene from the other area (West Atlantic and Indo-Pacific area). Phylogeny results showed that all 18 haplotypes of the species clustered into five clades with reasonably high bootstrap support of values (>64%). Overall, the tree topology for both phylogenetic and phenetic trees for 16S rDNA was similar. Both trees exposed two major clusters, one wholly containing the haplotypes of the T. lepturus species belonging to Indo-Pacific area with two major sister groups including Persian Gulf specimen and the other cleared the Western Atlantic and Japan individuals clustered in another distinct clade supporting the differentiation between the two areas. Phylogenic relationship observed between the Persian Gulf and the other Indo-Pacific Individuals suggested homogeneity between two mentioned areas. PMID:27822250

  13. How much can be learned from populations exposed to low levels of radiation

    The assessment of health effects from low-level exposure to radiation is a matter of considerable controversy. Many of the problems in analyzing and interpreting data on populations exposed to low levels of radiation are well illustrated by a current study of the effects on mortality of occupational exposure to radiation at the Hanford plant. The conclusion drawn is that the amount that can be learned from the Hanford population, and other populations exposed to low levels of radiation, is extremely limited. The data are not adequate to determine reliable estimates of risks, or to investigate the appropriateness of various models. Although there are problems in using data from populations exposed at high levels to estimate risks of low level exposure to radiation, the problems in obtaining such estimates directly are even more severe. Thus data from populations such as the Japanese A-bomb survivors and the British ankylosing spondylitis patients must continue to serve as our primary source of information on radiation effects. 27 references, 3 tables

    Rao, B.S.

    2002-01-01

    Epidemiological studies undertaken in many radiation exposed cohorts have played an important role in the quantification of radiation risk. Follow up of nearly 100,000 A-bomb survivors by the Radiation Effects Research Foundation (RERF), constitutes the most comprehensive human epidemiological study. The study population covered both sexes, different age groups and dose ranges from a few mSv to 2-3 Sv. Among nearly 90,000 cohorts, as on 1990, 54% are alive. Among these, 35,000 are those exposed as children at the age<20 years. Nearly 20 % of the mortalities (8,040) were due to cancer. It was estimated from the analysis of these data that among the cancers observed in LSS cohorts, 425±45 cases (335 solid cancers+90 leukaemias) were attributable to radiation exposure. Assuming a value of two for DDREF, ICRP 60, 1991 estimated a cancer risk of 5% per Sv for low dose and low dose rate exposure conditions. There have been a number of efforts to study the human populations exposed to low level radiations. Epidemiological studies on nuclear workers from USA, UK and Canada constituting 95,673 workers spanning 2,124,526 person years was reported by Cardis et al. (1995). Total number of deaths were 15,825, of which 3,976 were cancer mortalities. The excess relative risk for all cancers excluding leukaemia is -0.07 per Sv (-0.4- +0.3) and for leukaemia (excluding CLL) is 2.18 (0.1-5.7). Epidemiological studies in high background radiation areas (HBRA) of Yangjiang, China and coastal Kerala showed no detectable increase in the incidence of cancers or of any genetic disorders. Epidemiological studies in human populations exposed to elevated background radiation for several generations did not show any increase in the genetic disorders. Recent information on the background incidence of monogenic disorders in human populations and the recoverability factor of induced genetic changes suggests a risk much lower than the earlier ICRP estimates.

    2013-09-01

    Full Text Available This article intended to illustrate a profile of the role and impact of English in magazine print advertising in Iran, by examining the quantitative results obtained from discourse analysis. Three issues of Khanevadeh Sabz and two issues of Zendegi Ideal were collected and a total of 261 advertisements were analyzed. Results indicated that English has consistently been utilized in Persian magazine advertisements, representing attention-getting, persuasion, international brands, prestige, modernity, globalization, premium quality, fun, innovation and creativity. However, using English in Persian magazine advertisements is culturally and linguistically constrained. Culturally, in advertising traditional products English is only employed to introduce the name and e-mail address. Linguistically, although some English written slogans in Persian magazines had puns in them; the English used in Persian magazine advertisements mostly consists of easy-to-read vocabulary. Overall, in spite of the public’s generally low proficiency in English, it is predicted that English mixing will continue to thrive in magazine advertising discourse in Iran.

    Long-term radiation exposure affects human health. Ionizing radiation has long been known to raise the risk of cancer. In addition to high doses of radiation, low-dose ionizing radiation might increase the risk of cardiovascular disease, lens opacity, and some other non-cancerous diseases. Low- and high-dose exposures to ionizing radiation elicit different signaling events at the molecular level, and may involve different response mechanisms. The health risks arising from exposure to low doses of ionizing radiation should be re-evaluated. Health workers exposed to ionizing radiation experience low-dose radiation and have an increased risk of hematological malignancies. Reproductive function is sensitive to changes in the physical environment, including ionizing radiation. However, data is scarce regarding the association between occupational radiation exposure and risk to human fertility. Sperm DNA integrity is a functional parameter of male fertility evaluation. Hence, we aimed to report sperm quality and DNA damage in men from Jilin Province, China, who were occupationally exposed to ionizing radiation. Sperm motility and normal morphology were significantly lower in the exposed compared with the non-exposed men. There was no statistically significant difference in sperm concentration between exposed and non-exposed men. The sperm DNA fragmentation index was significantly higher in the exposed than the non-exposed men. Chronic long-term exposure to low doses of ionizing radiation could affect sperm motility, normal morphology, and the sperm DNA fragmentation index in the Chinese population. Sperm quality and DNA integrity are functional parameters that could be used to evaluate occupational exposure to ionizing radiation.

    The radiological accident in Goiania in 1987, resulted in a serious episode of human contamination, animal, plant and environmental were exposed to Cesium 137 chloride ( 137 CsCl) that caused contamination and accidental and occupational exposure to ionizing radiation. Ionizing radiation is one of the environmental components that causes most cellular stress in complex organisms. Exposure to ionizing radiation induces breaks in nucleic acids, especially, DNA double and single strand breaks. Chromosomal microarray analysis is an important tool for the detection and microdeletion and microduplications in the genomes. In this study we proposed to analyze the effect of exposure to RI on the formation of CNVs in an exposed human population occupationally to ionizing radiation from Cesium 137 during the accident in Goiania. The exposed group consisted of 07 families, of which at least one parent was occupationally exposed to ionizing radiation from Cesium 137, including a total of 25 individuals, do not know the absorbed dose of the military who were occupationally exposed to ionizing radiation. 11 families with a group of individuals not exposed to IR was used as control were used including a total of 33 individuals with no history of exposure to RI. The genotyping microarray was conducted in CytoScan HD system (Affymetrix®) without then analyzes was performed in ChAS® software. The statistical tests used were: Shapiro-Wilk, Mann- Whitney U, Spearman correlation, discriminant function analysis, binomial test, χ 2 test. All analyzes were performed using the statistical package SPSS 21.0, with a significance level of 5% (p <0.05). The frequency of CNVs were estimated loss / generation, gain / generation and burden / generation, representing 3,9 x 10 -5 , 6,8 x 10 -6 and 4,6 x 10 -5 respectively for the exposed group. For the control group, the frequencies were 2,1 x 10 -5 , 5,9 x 10 -6 and 3,1 x 10 -5 respectively. Thus, the frequency of CNVs showed statistically

    The color of urine is an important factor in urine examination, which can help physicians differentiate various diseases. Today, it is known that certain dyes, drug intoxications, and diseases can induce green urine discoloration. In the view of traditional Persian medicine, which is based on humoral medicine, green urine discoloration is generally referred to the dominance of coldness in the body. In fact, it is considered to be a result of a special kind of humoral imbalance and fluid depletion or retention in the human body. Persian scholars believed that green urine could be an indicator of intoxication or a predictor of an imminent spasm or convulsion in pediatric patients. Further investigations could result in finding new diagnostic scales of urine color based on the teachings of traditional Persian medicine. PMID:27103627

    In the present study the cytogenetic effects in hospital workers exposed to low-level radiation were evaluated. Samples of peripheral blood were collected from 63 subjects working in radiodiagnostics and from 30 subjects, working in the same hospitals, who were used as controls. A higher number of cells with chromosome-type aberrations (CA) was observed in the exposed workers vs. the controls and the difference was statistically significant (p<0.05). No correlation was, on the contrary, found between CA and years of exposure. A significant difference was observed in the incidence of cells with CA between smokers and non-smokers, but in the control group only. In contrast, in the workers exposed to ionizing radiation, the frequency of cells with CA was very similar in smokers and non-smokers. 13 refs.; 4 tabs

    Manifestations of dyslexia depend on language systems and scripts. This study explored the prevalence and clinical features of developmental dyslexia among monolingual Persian students and provided insights on mechanisms involved in reading Persian. To measure reading ability we developed a new instrument, Analysis of Persian Reading Ability, which had acceptable validity and reliability. A total of 1562 children aged 6 ½ - 14 were randomly selected from a population of 109696 primary school students in the city of Qom, Iran. Using a variety of statistical and clinical criteria, 82 (5.2%) of the sample were classified as dyslexics. A detailed analysis of reading errors revealed eight types of errors related to three categories. The most frequent category in both dyslexic and the matched control group was phonological, followed by pragmatic and visual errors. The observed prevalence rate of dyslexia and reading error categories would suggest that Persian in vowel-free format is an opaque language and predominant use of a sub-lexical strategy is involved when reading Persian.

    In the present study we analyzed and followed-up on the DNA damaging effects of microwave radiation of GEM radar equipment within microwave field of 10 μW/cm 2 to 10 mW/cm 2 in personnel occupationally exposed to frequency range of 1.5 GHz to 10.9 GHz. The single cell gel electrophoresis (SCGE)/comet assay as a tool for the bio monitoring of individuals accidentally, environmentally or occupationally exposed to physical or chemical agents was used to evaluate possible genotoxic effect on peripheral human blood lymphocytes. The comet assay is a method that allows efficient determination of single strand breaks (SSB) and double-strand breaks (DSB), as well as alkali-labile sites in the DNA of single cells. The comet assay was carried out under alkaline conditions. We measured the baseline comet assay effect in whole blood samples. Parameter of the comet assay was studied in workers occupationally exposed to microwave radiation of GEM radar and in corresponding unexposed control subjects. It was found that in the subjects who were occupationally exposed to microwave radiation, the levels of DNA damage increased compare to control group and showed interindividual variations. As a measure of DNA damage tail length was used, calculated from the centre of the head and presented in micrometers (μm). Mean value of exposed group was 13.54±1.44 as opposed to control mean value that was 13.15±1.39. Differences between mean tail lengths were statistically significant (P<0.05, ANOVA). The results of this study indicate that individuals occupationally exposed to microwave frequency of GEM radar equipment may experience an increased genotoxic risk, emphasizing the importance of individual bio monitoring, limiting exposure and radiation safety programs.

  6. Word-level prominence in Persian: An Experimental Study.

    Sadeghi, Vahid

    2017-12-01

    Previous literature on the phonetics of stress in Persian has reported that fundamental frequency is the only reliable acoustic correlate of stress, and that stressed and unstressed syllables are not differentiated from each other in the absence of accentuation. In this study, the effects of lexical stress on duration, overall intensity and spectral tilt were examined in Persian both in the accented and unaccented conditions. Results showed that syllable duration is consistently affected by stress in Persian in both the accented and unaccented conditions across all vowel types. Unlike duration, the results for overall intensity and spectral tilt were significant only in the accented condition, suggesting that measures of intensity are not a correlate of stress in Persian but they are mainly caused by the presence of a pitch movement. The findings are phonologically interpreted as suggesting that word-level prominence in Persian is typologically similar to 'stress accent' languages, in which multiple phonetic cues are used to signal the prominence contrast in the accented condition, and stressed and unstressed syllables are different from each other even when the word is not pitch-accented.

    A case report is presented of a 58 year old man who had for many years run an asbestos importing and fibreizing plant. He developed radiation pneumonitis following radiotherapy to a squamous cell carcinoma of the middle 3rd of the oesophagus. Detailed lung studies at autopsy revealed asbestos bodies associated with macrophages in many alveoli and areas of subpleural fibrosis typical of asbestos exposure. This was the most florid case of radiation seen in the Westminster Hospital for some years and the first seen in patients treated for carcinoma of the oesophagus using a three field technique. It is suggested that when planning radiotherapy to an asbestos-exposed patient, a possible increase in lung sensitivity to radiation should be considered when planning dosage. (U.K.)

    The aim of this study was to investigate the health condition of workers occupationally exposed to ionising radiation. The results for 1406 workers exposed to ionising radiations, who were regularly examined in 2004, were analysed using Statistica 5.0. The analysis included workers' case histories, frequency of illnesses and causes of temporary or permanent work disability. Of 1406 workers, 16 (1.13%) were found permanently disabled; in 11 the cause of disability was lens opacity, in 2 persistent trombocitophenia, and in 2 malignant tumour. Twenty-four workers were temporarily disabled, of whom 5 due to pregnancy. Thrombocytopenia was found in 12 men and only one woman. Anaemia was found in 4 women; dicentric chromosomes were the cause of temporary disability in one person, and tuberculosis in one person. Medical examinations of Croatian workers confirm low occupational exposure to ionising radiation. With this type of radiation, the established lens impairments could not be characterised as occupational. The two malignant tumours however were recognised as occupational diseases.(author)

    Translation, cross-culturally adaptation and validation of a Persian version of COOP/WONCA charts in Persian-speaking Iranians with multiple sclerosis (MS). The Persian version of COOP/WONCA charts was developed after a standard forward translation, synthesis and backward translation. A total of 197 subjects with MS participated in this study. They were asked to complete the COOP/WONCA charts and Short-Form 36 Health Survey (SF-36). The COOP/WONCA charts were re-administered to 50 patients, 4 weeks after the first session. Expanded Disability Status Scale (EDSS) was also scored for each subject by the referring physician. Construct validity was assessed by testing linear relationship between corresponding domains of the COOP/WONCA charts, the SF-36 and the EDSS. Test-retest reliability was examined using interclass correlation coefficient (ICC), standard error of measurement (SEM) and minimal detectable change (MDC) values. Related domains of COOP/WONCA charts and SF-36 demonstrated strong linear relationships with Spearman's coefficients ranging from -0.51 to -0.75 (p0.70) except for feelings and quality-of-life domains that were 0.50 and 0.51, respectively. The Persian version of the COOP/WONCA charts was shown to be psychometrically appropriate to evaluate the functional level and quality of life in Persian-speaking Iranians with MS. Implications for rehabilitation COOP/WONCA charts are now available in Persian and demonstrate good psychometric properties. COOP/WONCA charts demonstrate excellent reliability and construct validity in a Persian-speaking Iranian population with MS. Minimal detectable change in COOP/WONCA is now available in MS to guide within and between group analyses. Knowledge on a wide variety of physical, mental and emotional parameters as well as the status of patients' symptoms, daily activities and quality of life helps rehabilitation clinicians and service providers plan preventive and remedial interventions more effectively.

    To cross-culturally adapt the Achilles tendon Total Rupture Score (ATRS) to Persian language and to preliminary evaluate the reliability and validity of a Persian ATRS. A cross-sectional and prospective cohort study was conducted to translate and cross-culturally adapt the ATRS to Persian language (ATRS-Persian) following steps described in guidelines. Thirty patients with total Achilles tendon rupture and 30 healthy subjects participated in this study. Psychometric properties of floor/ceiling effects (responsiveness), internal consistency reliability, test-retest reliability, standard error of measurement (SEM), smallest detectable change (SDC), construct validity, and discriminant validity were tested. Factor analysis was performed to determine the ATRS-Persian structure. There were no floor or ceiling effects that indicate the content and responsiveness of ATRS-Persian. Internal consistency was high (Cronbach's α 0.95). Item-total correlations exceeded acceptable standard of 0.3 for the all items (0.58-0.95). The test-retest reliability was excellent [(ICC)agreement 0.98]. SEM and SDC were 3.57 and 9.9, respectively. Construct validity was supported by a significant correlation between the ATRS-Persian total score and the Persian Foot and Ankle Outcome Score (PFAOS) total score and PFAOS subscales (r = 0.55-0.83). The ATRS-Persian significantly discriminated between patients and healthy subjects. Explanatory factor analysis revealed 1 component. The ATRS was cross-culturally adapted to Persian and demonstrated to be a reliable and valid instrument to measure functional outcomes in Persian patients with Achilles tendon rupture. II.

    An outline is given of genetic counselling provided to 46 radiation-exposed persons during the period from 1978 to 1994. The radiation exposure had, in most cases, been due to radiation-therapeutic measures (n=22). To a low extent, counselling was carried out because of fear of genetic consequences of the Chernobyl reactor accident (n=11), preceding radiation exposure from X-ray (n=9) and nuclear diagnosis (n=1) as well as occupation radiation exposure (n=3). During counselling, information was given on the genetic risk to be expected, taking into consideration the risk factor that is valid at present and the malformation doubling dose. After performance of radiation therapy, an avoidance of conception for 2 years has been recommended. After termination of this period, in the case of an urgent wish of having children, pregnancy was not discouraged if no further risk factors existed. (orig.) [de

    The radiation risk radiometer-dosimeter (R3D)-R2 solid-state detector performed radiation measurements at the European Space Agency EXPOSE-R2 platform outside of the Russian "Zvezda" module at the International Space Station (ISS) from 24 October 2014 to 11 January 2016. The ISS orbital parameters were average altitude of 415 km and 51.6° inclination. We developed special software and used experimentally obtained formulas to determine the radiation flux-to-dose ratio from the R3DR2 Liulin-type deposited-energy spectrometer. We provide for the first time simultaneous, long-term estimates of radiation dose external to the ISS for four source categories: (i) galactic cosmic ray particles and their secondary products; (ii) protons in the South Atlantic Anomaly region of the inner radiation belt (IRB); (iii) relativistic electrons and/or bremsstrahlung in the outer radiation belt (ORB); and (iv) solar energetic particle (SEP) events. The latter category is new in this study. Additionally, in this study, secondary particles (SP) resulting from energetic particle interaction with the detector and nearby materials are identified. These are observed continuously at high latitudes. The detected SPs are identified using the same sorting requirements as SEP protons. The IRB protons provide the highest consistent hourly dose, while the ORB electrons and SEPs provide the most extreme hourly doses. SEPs were observed 11 times during the study interval. The R3DR2 data support calculation of average equivalent doses. The 30 day and 1 year average equivalent doses are much smaller than the skin and eyes doses recommendations by the National Council on Radiation Protection (Report 132), which provides radiation protection guidance for Low Earth Orbit.

    Despite intensive research over the last few decades, there still remains considerable uncertainty as to the genetic impact of ionising radiation on human populations, particularly at low levels. The aim of this study was to provide data on genetic hazards associated with occupational exposure to low doses of ionising radiation in nuclear medicine departments. The assessment of DNA damage in peripheral blood lymphocytes of medical staff was performed using the chromosome aberration (CA) test. Exposed subjects showed significantly higher frequencies of CA than controls. There were significant inter-individual differences in DNA damage within the exposed population, indicating differences in genome sensitivity. Age and gender were not confounding factors, while smoking enhanced the levels of DNA damage only in control subjects. The present study suggests that chronic exposure to low doses of ionising radiation in nuclear medicine departments causes genotoxic damage. Therefore, to avoid potential genotoxic effects, the exposed medical personnel should minimise radiation exposure wherever possible. Our results also point to the significance of biological indicators providing information about the actual risk to the radiation exposed individuals.(author)

  17. Effects of Ionizing Radiation in Atopic Patients Exposed to Radiation

    Atopic dermatitis is a chronic relapsing inflammatory skin disease that arises most commonly during early infancy, and is characterized by severe pruritus, age-dependant skin manifestations, and a fluctuating clinical course. Hereditary, environmental and immunological factors are involved in the aetiopathogenesis of AD. Also the differentiation of helper T- cells, local cytokine profile, IgE, infectious agents and superantigens are factors identified as being involved in the pathogenesis of AD. One hundred patients with AD were selected from the outpatient clinic of the National Center for Radiation Research and Technology in Cairo, Egypt. They were divided into 2 groups; group 1 included radiation workers in the Hall of gamma irradiation unit and group 2 included workers outside controlled area and not exposed to radiation with comparable age and sex. The severity of the disease was evaluated according to the grade of atopic dermatitis. Total and specific serum IgE was measured and Complete Blood Count was also carried out. Four Malassezia species were isolated from AD patients M. globosa, M. furfur, M. sympodialis and M. obtusa. The clinical isolates consisted of two bacterial strains, S. aureus and S. epidermidis. The significant increase of AD severity seems to be more closely related to the prevalence of S. aureus and Malassezia on the skin of radiation workers. This was proved by the presence of high IgE and eosinophils in radiation workers. So, the interactions of low gamma radiation and skin seems to further complicate the risk of assessments of atopic dermatitis

    The purpose of the study was to analyze the reproductive function in individuals exposed to radiation in the riverside villages on the Techa in the Southern Urals. The exposure of the population, numbering 28000, occurred in 1950-1956 as a result of discharges into the river of radioactive wastes from the Mayak facility for processing weapon plutonium. The residents were exposed to chronic radiation, both external and internal. The range of exposure doses to gonads was sufficiently wide: 20-1270 mSv. However, the distribution of doses among the exposed individuals was ununiform, and the proportion of people whose dose was below 120 mGy accounted for 74%. The following characteristics of exposed women were analyzed: menstrual function, outcomes of pregnancy, birth rates, health status for newborns. The analysis of the menstrual function in exposed women showed that in persons exposed in childhood, menarche was registered at the age of 14.3 years, on the average (based on literature sources, menarche is attained at the age of 13 for unexposed population). The mean age at menopause was 47.9 years for exposed women (the respective mean value for Russia is 50.8 years). Pregnancy outcomes were analyzed in 9000 exposed women. The rate of medical and criminal abortions was estimated as 79 per 100 labors. The rate of spontaneous abortions for exposed women was slightly higher, 3.11%, than for controls, 2.30%; these difference, however, were statistically insignificant. The total loss of fetus or neonate (unfavorable outcomes of pregnancy: spontaneous abortions, stillbirths, early neonatal death) was estimated to be 4.58% at zero dose. Exposure to gonads at the dose 1 Sv, estimated using the above-indicated method, yielded 3% of additional unfavorable outcomes of pregnancy. It was shown, based on the analysis of birth rates for the Techa Cohort that they had not undergone any essential changes over the first 25 years of exposure compared to the respective coefficients for

    In this study we present the risk of cataract among medical staff in neurosurgical department occupationally exposed to radiation compared to those of non-radiation workers. Cataract is the most common degenerative opacity of the crystalline lens developing with aging. Other risk factors for cataract are: infrared and ultraviolet radiation, systemic diseases (diabetes, hypertonic disease), eye diseases (glaucoma, high myopia), drugs (steroids), etc. High risk of developing cataract we find among staff occupationally exposed to radiation during operations - interventional cardiologists and neurosurgeons. This study includes 30 people between 33 and 60 years of age working in neurosurgical department and control group (the same amount and age of people not exposed to radiation in their work). After visual acuity measurement, the lens was examined by retroillumination method (red reflex) and using a bio microscope. The patients were asked for presence of ocular and systemic diseases, eye trauma, drug, alcohol and tobacco abuse and for how many years they work in this department. There was one case with cataract among neurosurgeons. The doctor doesn't have eye or systemic diseases, doesn't take any drugs and is not alcohol or tobacco abuser. In the control group there were two persons with subcapsular cataract but they have diabetes. Radiation is one of the risk factors for cataract. Continuing of this epidemiological survey will provide further knowledge on the potential risk of occupational radiation-induced cataract among neurosurgical staff and will contribute for optimization of radiation protection.

    Full Text Available Post-mortem studies have suggested a link between the thalamus, psychiatric disorders, and suicide. We evaluated the thalamus and anterior thalamic radiations (ATR in a group of Veterans with and without a history of suicidal behavior (SB to determine if thalamic abnormalities were associated with an increased risk of SB. Forty Veterans with mild traumatic brain injury (TBI and no SB (TBI-SB, 19 Veterans with mild TBI and a history of SB (TB+SB and 15 healthy controls (HC underwent MRI scanning including a structural and diffusion tensor imaging scan. Suicidal behaviors were evaluated utilizing the Columbia Suicide Rating Scale and impulsivity was measured using the Barratt Impulsiveness Scale (BIS. Differences in thalamic volumes and ATR fractional anisotropy (FA were examined between 1 TBI+SB versus HC and 2 TBI+SB versus combined HC and TBI-SB and 2 between TBI+SB and TBI-SB. Left and right thalamic volumes were significantly increased in those with TBI+SB compared to the HC, TBI-SB and the combined group. Veterans with TBI+SB had increased FA bilaterally compared to the HC, HC and TBI-SB group, and the TBI-SB only group. Significant positive associations were found for bilateral ATR and BIS in the TBI+SB group. Our findings of thalamic enlargement and increased FA in individuals with TBI+SB suggest that this region may be a biomarker for suicide risk. Our findings are consistent with previous evidence indicating that suicide may be associated with behavioral disinhibition and frontal-thalamic-limbic dysfunction and suggest a neurobiologic mechanism that may increase vulnerability to suicide.

    Full Text Available Cross-cultural studies of speech acts in different linguistic contexts might have interesting implications for language researchers and practitioners. Drawing on the Speech Act Theory, the present study aimed at conducting a comparative study of request speech act in Persian and English. Specifically, the study endeavored to explore the request strategies used in daily interactions of Persian and English speakers based on directness level and supportive moves. To this end, English and Persian TV series were observed and requestive utterances were transcribed. The utterances were then categorized based on Blum-Kulka and Olshtain’s Cross-Cultural Study of Speech Act Realization Pattern (CCSARP for directness level and internal and external mitigation devises. According to the results, although speakers of both languages opted for the direct level as their most frequently used strategy in their daily interactions, the English speakers used more conventionally indirect strategies than the Persian speakers did, and the Persian speakers used more non-conventionally indirect strategies than the English speakers did. Furthermore, the analyzed data revealed the fact that American English speakers use more mitigation devices in their daily interactions with friends and family members than Persian speakers.

    We investigated the influence of exogenously administered melatonin on adult rats eye lenses exposed to ultraviolet radiation (UV) A and B ranging from 356-254 nm irradiation at 8 microW/cm(2). Rats exposed to this range of UV for 15 min for one week showed a significant (PUV-radiation significantly (PUV irradiation, may be the main cause of lens opacification. Melatonin injection with radiation significantly reduced (Pradiation, SOD and GSH-Px enzyme activities increased significantly (PUV radiation was as effective as melatonin treatment concurrent with UV irradiation. We conclude that melatonin may protect the eye lens from the damaging effects of UV exposure, and its actions protect lens from oxidative stress, elevating Ca(2+) levels, which are considered as an important causes of cataractogenesis.

    This work describes the long term genetic monitoring of the Goiania population exposed to ionizing radiation from 137 Cs, using cytogenetic and molecular endpoints. Cytogenetically, micronucleus frequencies differentiated groups exposed to different levels of radiation. Two molecular methods were employed: 1) the hprt clonal assay, involving in vitro selection of 6-thioguanine-resistant hprt mutant clones which were characterized at the molecular level using RT-PCR and genomic analysis. Ionizing radiation exposure initially elevated hprt mutation frequency which gradually diminished, so that no significant increase was observed four and a half years after original exposure. The spectrum of hprt mutations recovered from ten individuals exposed to relatively high doses of radiation revealed a fourfold increase in the frequency of A:T → G:C transitions. The increase is consistent with the effects of ionizing radiation in prokaryotes and lower eukaryotes. Additionally, a twofold increase in the frequency of deletions was observed which may reflect radiation induced DNA strand breakage; 2) determination of microsatellite instability using fluorescent PCR and genomic DNA from mononuclear cells. The frequency distributions of somatic microsatellite alterations in exposed and non-exposed populations were not different. Our assay lacked sensitivity to discriminate between spontaneous and induced microsatellite instability and therefore, is not suitable for population monitoring. Finally, we estimated the risk associated with radiation exposure for the exposed Goiania population. The estimated genetic risk of dominant disorders in the first post-exposure generation was increased nearly twenty-fourfold. The risk of carcinogenesis was increased by a factor of 1.5. (author)

    Biogenic Calcium Carbonate, particularly as naturally thermoluminescent calci tic mollusc shells may serve as excellent radio thermoluminescent dosimeters. In this study the radio thermoluminescence properties of 8 different bivalves of the Persian Gulf, the Oman Sea and the internal calcite shell of Sepia sp. are investigated. The results of this investigation have shown that the shells of Sepia sp., Pinctata radiata and Card ita bicolor as appropriate dosimeters for both personal and industrial dosimetry purposes, among which Sepia sp. is the most sensitive one. Callista umbonella and Mactra sp. are relatively less thermoluminescent while Saccostrea Cucullata and Chlamys ruschenbergerii are completely inert with respect to γ - thermoluminescence. Thermoluminescence properties of Anadara refescens and Anadara secticostata decrease surprisingly by an increase in the absorbed dose of γ radiation, which can mainly be interpreted as the result of crystal lattice destruction caused by ionizing radiation

    Persian language is the official language of Iran, Tajikistan and Afghanistan. Local online users often represent their opinions and experiences on the web with written Persian. Although the information in those reviews is valuable to potential consumers and sellers, the huge amount of web reviews make it difficult to give an unbiased evaluation to a product. In this paper, standard machine learning techniques SVM and naive Bayes are incorporated into the domain of online Persian Movie reviews to automatically classify user reviews as positive or negative and performance of these two classifiers is compared with each other in this language. The effects of feature presentations on classification performance are discussed. We find that accuracy is influenced by interaction between the classification models and the feature options. The SVM classifier achieves as well as or better accuracy than naive Bayes in Persian movie. Unigrams are proved better features than bigrams and trigrams in capturing Persian sentiment orientation.

    Veterans who have participated in the Gulf War suffer from a number of symptoms, collectively referred to as the Gulf War Syndrome. It has been hypothesized that a change in the systemic cytokine balance or other changes in immunological parameters could be responsible for some of the symptoms. We...... analyzed the peripheral blood natural killer (NK) cell activity of 686 Gulf War personnel who had been present in the Persian Gulf area during and immediately after the Gulf War as well as 231 gender and age-matched controls. The test material included individual samples of frozen peripheral blood...

    Full Text Available Introduction: Lengthy clinical and epidemiological studies at the Research Institute of Radiation Medicine and Ecology have discovered basic patterns of long-term effects from ionizing radiation in population groups exposed to radiation risk. Methodology for calculating injury from radiation risk factors has been developed and implemented to minimize the effects of the Semipalatinsk nuclear test site (SNTS. Material and methods: We analyzed materials from the database of the Scientific Medical Register that were exposed to radiation as a result of SNTS. We analyzed both male and female populations of the Abay, Beskaragai and Zhanasemei, Kokpekti (control areas of East-Kazakhstan region (EKR from 2008-2012. These populations were split into three groups allocated by the generation. The first group represented persons born from the period of 01/01/1930 -08/01/1949 and their children born from the period of 10/09/1949-12/31/1962. The second group were persons born after 01/01/1963. The third group served as the control and were persons who immigrated to these areas after 1990. Results: There was an increased incidence of cancer (21.5%, p < 0.000734, cardiovascular diseases (10.2%; respiratory problems (9.6%, gastrointestinal issues (9.1%, p < 0.00371-0.00679 in the first group. The effect of the radiation dose has not been fully stuided among the subjects in the second group.The major causes of excess mortality in the first group were neoplams (30.6%, hypertension (23.8%, and myocardial infarction (22.6%. The effects of radiation influenced mortality in the second group were 2-2.5 times lower than the first group.Conclusion: There is a correlation between the size of the radiation dose, the risk profile, and age at the moment of radiation exposure with trends of morbidity and mortality in the radiation exposed areas.

    More than 100,000 US troops were potentially exposed to chemical warfare agents sarin (GB) and cyclosarin (GF) when an ammunition dump at Khamisiyah, Iraq was destroyed during the 1991 Persian Gulf War (GW). We previously found reduced total gray matter (GM) volume in 40 GW veterans with suspected GB/GF exposure relative to 40 matched, unexposed GW veterans on a 1.5T MR scanner. In this study, we reexamine the relationship between GB/GF exposure and volumetric measurements of gross neuroanatomical structures in a different cohort of GW veterans on a 4T MR scanner. Neuropsychological and magnetic resonance imaging (MRI) data from a cross sectional study on Gulf War Illness performed between 2005 and 2010 were used in this study. 4T MRI data were analyzed using automated image processing techniques that produced volumetric measurements of gray matter (GM), white matter (WM) and cerebrospinal fluid (CSF). Binary comparisons of 64 GB/GF exposed veterans and 64 'matched', unexposed veterans revealed reduced GM (p=0.03) and WM (p=0.03) volumes in the exposed veterans. Behaviorally, exposed veterans committed more errors of omission (p=0.02) and tended to have slower responses (p=0.05) than unexposed veterans on the Continuous Performance Test (CPT), a measure sustained and selective attention. Regression analyses confirmed that GB/GF exposure status predicted GM (β=-0.11, p=0.02) and WM (β=-0.14, p=0.03) volumes, and number of CPT omission errors (β=0.22, p=0.02) over and above potentially confounding demographic, clinical, and psychosocial variables. There was no dose-response relationship between estimated levels of GB/GF exposure and brain volume. However, we did find an effect of Gulf War Illness/Chronic Multisymptom Illness on both GM and WM volume in the GB/GF exposed veterans. These findings confirm previous reports by our group and others of central nervous system pathology in GW veterans with suspected exposure to low levels of GB/GF two decades after the

    The health effects of exposing to ionizing radiation are attracting great interest in the space exploration community and patients considering radiotherapy. However, the impact to metabolism after exposure to high dose radiation has not yet been clearly defined in livers. In the present study, 1H nuclear magnetic resonance (NMR) based metabolomics combined with multivariate data analysis are applied to study the changes of metabolism in the liver of C57BL/6 mouse after whole body exposure to either gamma (3.0 and 7.8 Gy) or proton (3.0 Gy) radiation. Principal component analysis (PCA) and orthogonal projection to latent structures analysis (OPLS) are employed for classification and identification of potential biomarkers associated with gamma and proton irradiation. The results show that the radiation exposed groups can be well separated from the control group. At the same radiation dosage, the group exposed to proton radiation is well separated from the group exposed to gamma radiation, indicating different radiation sources induce different alterations based on metabolic profiling. Common to both gamma and proton radiation at the high radiation doses studied in this work, compared with the control groups the concentrations of choline, O-phosphocholine and trimethylamine N-oxide are decreased statistically, while those of glutamine, glutathione, malate, creatinine, phosphate, betaine and 4-hydroxyphenylacetate are statistically and significantly elevated after exposure to radiation. Since these altered metabolites are associated with multiple biological pathways, the changes suggest that the exposure to radiation induce abnormality in multiple biological pathways. In particular, metabolites such as 4-hydroxyphenylacetate, betaine, glutamine, choline and trimethylamine N-oxide may be good candidates of pre-diagnose biomarkers for ionizing radiation in liver.

    The main reason for the emergence of rows in Persian poetry is its prosodic function that has already been paid less. I just found something in the book Ghosn al-ban which the author had some similar view to the row. In this study, we made our attempt to show another reason for the entry and spread of the row in Persian poetry by means of a new approach. It should also be noted that in these lines to avoid as much as possible the repetitive and stereotyped points regarding the row.

    Ionising radiation is a ubiquitous environmental physical agent whose DNA damaging effects are fairly well established. The effects of low-level exposure to ionizing radiation are of concern to large number of people, including workers receiving radiation exposure on the job. Medical radiation workers are employees of hospitals, clinics and private offices where radiation is used in the process of delivering health care to humans. These workers can be categorised into two groups exposed employees who receive at least a minimum detectable exposure during a one-year period, and potentially exposed employees who work in the vicinity of radiation but whose exposures are below detectable limits. The exposure of patients and workers to radiation in medicine is a direct consequence of the use of radiation to improve the health of the individuals. Trends in radiation exposure of both patients and workers are effected not only by developments in radiation protection, but also by dose in the practice of medicine. It is very important to estimate absorbed doses from individuals occupationally exposed to ionizing radiation for carrying out radioprotection procedures and restrict the hazards to human health. The extent of health hazards is difficult to assess. Therefore, development of procedures that can be used to precisely identify health hazards in the exposed populations is a most significant approach towards establishing effective programs for disease prevention

    To examine the assumption that postdeployment incidence of sickness and other absence from work are higher among Gulf War Veterans compared with nonveterans. A prospective registry study including a cohort of 721 Danish Gulf War Veterans and a control cohort of 3,629 nonveterans selected from the general Danish population. Outcome measures were up to 23 years postdeployment incidence of (1) long-term sickness absence and (2) long-term all types of absence from work. Long term with regard to sickness and other absence was defined as exceeding 8 weeks. The association between outcomes and information on deployment history was studied using time-to-event analysis. The index date was the return date from the last deployment to the Gulf. The follow-up period was the time from index date until April 27, 2014. As the main finding, no difference was found between veterans and nonveterans in the incidence rate of long-term sickness absence. After an initial short period (3 months) with elevated incidence rate of long-term absence from work among veterans, there was no difference between the cohorts. Among Danish Gulf War Veterans, no postdeployment increased risk of long-term sickness absence or long-term absence from work was found as compared with nonveterans.

    Complete text of publication follows. Objective: This study was aimed at detecting both the incidence of chromosomal aberrations and changes in the hematological parameters as biomarkers of possible radiation injury among workers occupationally exposed to low levels of ionizing radiation and detecting the dose-effect relationship. Methods: Samples of peripheral blood were collected from 38 male industrial radiographers exposed to ionizing radiation for 1-16 years and from 24 age- and sex-matched healthy blood donors without radiation history served as control group. All radiation workers were routinely monitored with film badge. Cytogenetic analysis in peripheral blood lymphocytes assessed by the conventional chromosome aberration assay and at least 200 metaphases for each person were scored. The collected blood samples were analyzed for hematological assay using an automatic analyzer Sysmex KX-21, where 14 different parameters were computerized. Mann-Whitney U test was used to compare the frequencies of the unstable aberrations and hematological parameters between test and control groups. Dose-effect relationship and the influence of age and duration of employment was tested by regression analysis. Results and conclusion: The mean frequencies of dicentric and acentric chromosome aberrations were significantly higher in the exposed group than in the control group (P< 0.0005). No correlation between chromosomal aberrations and physical dose and age was observed in the exposed group. Also there is no clear relation between chromosome damage and duration of exposure. However, the increase in chromosome aberrations in the exposed group was not followed by a corresponding hematological depression. The average values of hematological indices were within the reference levels and did not show any significant differences with control group. A tendency of decreasing the absolute lymphocyte count within the referential levels was the only hematological effect in radiation

    Chromosomal aberrations are fairly reliable indicators of damage induced by ionising radiation. This study included 180 radiologists and medical radiographers (technicians) and 90 controls who were not occupationally exposed to ionising radiation. All exposed subjects were routinely monitored with film badge, and none was exposed to a radiation dose exceeding the limit for occupational exposure recommended by the International Commission on Radiological Protection (ICRP). Two hundred metaphases for each person were scored. The frequencies of acentric fragments, dicentrics, ring chromosomes and chromosomal exchanges were determined and compared to those obtained in the control group. Chromosome aberrations were analysed using Poisson regression for profession, age, sex, smoking and years of exposure. Age, smoking, diagnostic exposure to X-rays and occupation were found to correlate with the occurrence of acentric fragments. The influence of exposure duration on the frequency of acentric fragments was greater in medical radiographers than in radiologists. Smoking and sex were found to correlate with the occurrence of dicentric chromosomes, which were more common in men than in women. As chromosome aberrations exceeded the expected level with respect to the absorbed dose, our findings confirm the importance of chromosome analysis as a part of regular medical check-up of subjects occupationally exposed to ionising radiation.(author)

    There is a paucity of data regarding the association between occupational radiation exposure and risk to human fertility. Recently, we provided the first evidence on altered sperm functional characteristics, DNA damage and hypermethylation in radiation health workers. However, there is no report elucidating the association between seminal plasma antioxidants and sperm chromatin integrity in occupationally exposed subjects. Here, we assessed the seminal plasma antioxidants and lipid peroxidation level in 83 men who were occupationally exposed to ionizing radiation and then correlated with the sperm chromatin integrity. Flow cytometry based sperm chromatin integrity assay revealed a significant decline in αt value in the exposed group in comparison to the non-exposed group (P<0.0001). Similarly, both total and reduced glutathione levels and total antioxidant capacity in the seminal plasma were significantly higher in exposed group than the non-exposed group (P<0.01, 0.001 and 0.0001, respectively). However, superoxide dismutase level and malondialdehyde level, which is an indicator of lipid peroxidation in the seminal plasma, did not differ significantly between two groups. The total antioxidant capacity (TAC) and GSH level exhibited a positive correlation with sperm DNA integrity in exposed subjects. To conclude, this study distinctly shows that altered sperm chromatin integrity in radiation health workers is associated with increase in seminal plasma antioxidant level. Further, the increased seminal plasma GSH and TAC could be an adaptive measure to tackle the oxidative stress to protect genetic and functional sperm deformities in radiation health workers. - Highlights: • Seminal plasma antioxidants were measured in men occupationally exposed to radiation. • Sperm chromatin integrity was significantly affected in the exposed group. • Glutathione and total antioxidant capacity was significantly higher in exposed group. • Sperm DNA damage in exposed subjects

    More than 100,000 US troops were potentially exposed to chemical warfare agents sarin (GB) and cyclosarin (GF) when an ammunition dump at Khamisiyah, Iraq was destroyed during the 1991 Gulf War (GW). We previously reported reduced hippocampal volume in GW veterans with suspected GB/GF exposure relative to matched, unexposed GW veterans estimated from 1.5T magnetic resonance images (MRI). Here we investigate, in a different cohort of GW veterans, whether low-level GB/GF exposure is associated with structural alterations in specific hippocampal subfields, estimated from 4T MRI. The Automatic Segmentation of Hippocampal Subfields (ASHS) technique was used to quantify CA1, CA2, CA3 and dentate gyrus (DG), and subiculum (SUB) subfields volumes from high-resolution T2-weighted images acquired on a 4T MR scanner in 56 GW veterans with suspected GB/GF exposure and 56 "matched" unexposed GW veterans (mean age 49±7 years). GB/GF exposed veterans had smaller CA2 (p=0.003) and CA3/DG (p=0.01) subfield volumes compared to matched, unexposed GW veterans. There were no group difference in total hippocampal volume, quantified with FreeSurfer, and no dose-response relationship between estimated levels of GB/GF exposure and total hippocampal or subfield volume. These findings extend our previous report of structural alterations in the hippocampi of GW veterans with suspected GB/GF exposure to volume changes in the CA2, CA3, and DG hippocampal subfields in a different cohort of GW veterans with suspected GB/GF exposure.

    In the current study the modulatory role of mobile phone radio-frequency electromagnetic radiation (RF-EMR) on emotionality and locomotion was evaluated in adolescent rats. Male albino Wistar rats (6-8 weeks old) were randomly assigned into the following groups having 12 animals in each group. Group I (Control): they remained in the home cage throughout the experimental period. Group II (Sham exposed): they were exposed to mobile phone in switch-off mode for 28 days, and Group III (RF-EMR exposed): they were exposed to RF-EMR (900 MHz) from an active GSM (Global system for mobile communications) mobile phone with a peak power density of 146.60 μW/cm(2) for 28 days. On 29th day, the animals were tested for emotionality and locomotion. Elevated plus maze (EPM) test revealed that, percentage of entries into the open arm, percentage of time spent on the open arm and distance travelled on the open arm were significantly reduced in the RF-EMR exposed rats. Rearing frequency and grooming frequency were also decreased in the RF-EMR exposed rats. Defecation boli count during the EPM test was more with the RF-EMR group. No statistically significant difference was found in total distance travelled, total arm entries, percentage of closed arm entries and parallelism index in the RF-EMR exposed rats compared to controls. Results indicate that mobile phone radiation could affect the emotionality of rats without affecting the general locomotion.

    This study aimed to translate the original English version of the Geriatric Oral Health Assessment Index (GOHAI) into a Persian version and to assess the preliminary psychometric properties of the translated index among a sample of Persian elders. Twelve items included in GOHAI were first translated into Persian using a back-translation technique and then were compared with the original version. Four hundred and seventeen elderly subjects who were admitted to a day care centre answered GOHAI and an attached socio-demographic questionnaire. Internal consistency of the Persian version was measured by Cronbach's alpha. Test-retest reliability was assessed by intraclass correlation coefficient (ICC) and weighted kappa. Factor structure of GOHAI was evaluated by principal component factor analysis. Mean of GOHAI score was 45.71 (SD: 5.14; range: 27-51). The mean of GOHAI score was higher for the elders who rated their oral and general health as 'good'. The Cronbach's alpha for GOHAI score was 0.748, indicating a high degree of internal consistency and homogeneity between the GOHAI items. The test-retest correlation for the total GOHAI score using ICC was 0.763 (95% CI = 0.713-0.809). Factor analysis revealed a three-factor solution that bolstered the theoretical construction of the index. Significant differences in the GOHAI scores were found for income and current number of teeth. The Persian version of the GOHAI can be used reliably to identify oral health-related concerns of older Persian speakers, but further research is needed to confirm its cultural consonance in this population. © 2014 John Wiley & Sons A/S and The Gerodontology Association.

    Eight 'rogue' lymphocyte metaphases containing a large number of aberrant chromosomes were noted during a survey of chromosomal damage in 328 Belarussian children. The study population comprised children of families living in territory contaminated by radiation from the Chernobyl accident. The majority of the sample had been evacuated within 1 week from very heavily polluted territory to areas that had received much less fallout. Two hundred cells were scored per subject and one rogue cell was found in a child exposed in utero; one in a child conceived after the accident and six in the postnatally exposed group. The possibility that the damage was due to exposure to radio-iodine concentrated in the thyroid gland, or to radiation from incorporated hot particles' of an alpha or beta/gamma emitter is discussed. It is concluded that the damage to these cells is unlikely to have been caused by radiation. (Author)

    The most commonly used instrument for the research and treatment of excessive internet use is Young's Internet Addiction Test (IAT). While the IAT has been translated to several languages (including Persian) and has demonstrated good psychometric properties across several independent studies, there is still a room for alternative assessment instruments. This study reports a validation of the Persian version of the Problematic Internet Use Questionnaire (PIUQ). A sample (n = 296) from Kerman, Iran was administered the translated Persian version of the PIUQ as well as the Persian version of the University of California, Los Angeles (UCLA) Loneliness scale, Satisfaction With Life scale, and questions related to use of technology and the internet. Analyses using confirmatory and exploratory factor analyses demonstrated that the Persian version of the PIUQ had good internal reliability and concurrent validity (with loneliness and satisfaction with life), but they also had an alternative factor structure that did not support the original factor structure. The Persian version of the PIUQ produced adequate psychometric properties (internal reliability and concurrent validity), but care should be taken in the interpretation of the factor structure.

  11. Surveillance of health care workers exposed to ionising radiation: Rimed pilot study

    International Nuclear Information System (INIS)

    2008-01-01

    The project so-called RIMED aimed to set up epidemiological surveillance of health care workers exposed to ionizing radiation. A pilot study was conducted in a sample of hospital personnel to examine the possibility of identifying exposed subjects in order to analyse mortality patterns according to occupational characteristics such as medical departments or occupations in a historical cohort. Seven hospitals participated in this pilot study. Health-care workers who had worn a dosimeter up to December 2003 were to be included in this cohort. The subjects' identification data were obtained from the SISERI (Systeme d'information de la surveillance de l'exposition aux rayonnements ionisants - Ionizing Radiation Exposure Monitoring Information System) database managed by the Institut de radioprotection et de surete nucleaire - Radiation Protection and Nuclear Safety Institute (IRSN). The SISERI system was in a 'pilot' phase in 2004. According to SISERI database, a total of 5126 subjects were found to have worn a dosimeter up to December 2003. The subjects' identification data were completed by the administrative services of the hospitals and occupational physicians searched for subjects' occupational data. Information required for the vital status search was satisfactorily completed only for 38% of the cohort subjects. This pilot study showed that obtaining data from SISERI database completed by hospital administrative data in 2004 led to a database of insufficient quality for epidemiological surveillance. The Institut de veille sanitaire (French Institute of Public Health Surveillance) recommends that transmission by the employers of some specific personal or occupational data of the exposed subjects should be made compulsory. In this way, SISERI system should be able to constitute any database with required quality for epidemiological surveillance of ionizing radiation exposed subjects. (authors)

    The experiences of the last ten years have shown that the measures of the First Radiation Protection Ordinance generally proved to be sufficient for the protection of the employed or of the patients. They had to be amended in so far as the exposure to radiation for those occupationally exposed can be reduced. This results in changes to the regulations so that certain groups of persons can also be effectively controlled. The recognition that medical supervision for radiation protection reasons is reasonable only if exposure has occurred should be additionally utilized in the regulations if the Euratom standards make this possible. The protection of patients attains some new rules which can be derived from handling and from therapeutical use. In this case too experience resulted in a more reasonable application of ionizing radiation and radioactive materials than was expected when the First Radiation Protection Ordinance was issued.

    Recognition of death anxiety experienced by patients who have survived violence and threats to life during war is of strong importance in delivery of best care for veterans experiencing health stressors. The aim of the study was to explore the death anxiety experience of veterans from the Iran-Iraq war. Using a phenomenological approach, 11 war veterans were interviewed related to death anxiety experiences. Four major themes included afterlife fears; alienated farewell; ambiguous separation; and physical dissolution. Patients who have been exposed to death trauma in the battlefield may carry added burden from unique cognitions and fears related to personal death.

    Chromosome aberrations and sister chromatid exchanges (SCEs) were determined in standard peripheral lymphocyte metaphase preparations of 13 British Gulf War veterans, two veterans of the recent war in the Balkans, and one veteran of both wars. All 16 volunteers suspect exposures to depleted uranium while deployed at the two different theatres of war in 1990 and later on. The Bremen laboratory control served as a reference in this study. Compared with this control there was a statistically significant increase in the frequency of dicentric chromosomes (dic) and centric ring chromosomes (cR) in the veterans' group, indicating a previous exposure to ionising radiation. The statistically significant overdispersion of dic and cR indicates non-uniform irradiation as would be expected after non-uniform exposure and/or exposure to radiation with a high linear energy transfer. The frequency of SCEs was decreased when compared with the laboratory control. (author)

    Persian sturgeon frys were exposed to different concentrations of copper sulfate and potassium permanganate in order to the evaluation of their impacts on bacterial load of skin, gill and surrounding water and also the histopathological alternations of gill tissue. For this purpose, the sublethal doses were determined after a pre-test and then the experiment was done in 4 (for copper sulfate: 0.07, 0.14, 026 and 0.5 mg/l) and 5 (for potassium permanganate: 0.07, 0.14, 026, 0.5 and 1 mg/l) treatments with three replicates inside the glass aquaria. Also, one group without disinfecting drug was considered as control for each experiment. The microbial and histopathological investigations were done after 96 h exposure. According to our results, a range of histopathological alternations were observed in gills tissue including mucus coagulation and secretion, hyperplasia, lamellar necrosis, hyperplasia, lamellar adhesion, haemorrhage, thickening of secondary lamellae, hypertrophy of supporter cartilage, clubbing of gill lamellae and sliming of primary lamellae. The severity of these alternations increased with increasing of the doses of the copper sulfate and potassium permanganate. The bacterial load (CFU/g) of gill, skin and surrounding water was lower in 0.07 mg/l copper sulfate treatment and 1 mg/l potassium permanganate treatment (P permanganate have disinfecting effects on bacterial load of gill, skin and surrounding water, although this is along with some histopathological alternations. Also, it seems that the copper sulfate has higher disinfecting power than potassium permanganate.

    The general principles of medical surveillance for workers exposed to ionizing radiation were defined in the Euratom Basic Standards in 1959. These principles, which are in accordance with the early IGRP publications, have been adopted by the national authorities and implemented without difficulty. However, because of the forthcoming publication of the revised Basic Standards- in accordance with recent IGRP recommendations, the Commission decided to organize a meeting of doctors responsible for the medical surveillance of workers exposed to ionizing radiation in order to disseminate as widely as possible the results of experience gained in the field of radiological protection and to pinpoint the practical difficulties which might arise when the principles were applied. The Commission also considered it important to inform doctors specializing in radiological protection about the principles to be followed by those responsible for the health protection of workers exposed to non-ionizing radiation, particularly microwaves and Laser beams.

    For the last 60 years, some huge radioecological accidents and catastrophes have taken place, connected with nuclear weapon use in war, nuclear weapon tests on the nuclear test sites of Nevada, Semipalatinsk, Loob-Nor and the disturbance of the technological cycle at the enterprises of atomic industry and NPP. The scientific-technical program is being carried out at the Scientific research Institute of Radiation medicine and Ecology. The one of the its major task is to create the Scientific Automated Medical Register for the Kazakhstan population exposed to radiation. The aim of this program is a long-term automated personnel registering of population exposed to radiation in consequences of on nuclear testing on the Semipalatinsk Test Site, evolution of health condition and its changes, prediction for taken optimal decisions upon minimization of post-radiation consequences. Thus, main tendencies of Register creation are registration of the extent and characteristics of concrete man-caused factor (including radioactive), the number and age-sexual peculiarities of the risk group, medical information according to qualitative and quantitative parameters of different nosological forms of radiation induced diseases, and the duration of stay of definite patient under risk. After formatting of effective equivalent doses the information allows not only containing radiation risk, but also working out medical-social activities, directed to decrease the risk up to the level of average Republican standards.

    The purpose of the study was to examine the psychometric properties of the Persian version of the Care Dependency Scale (CDS) in nursing homes. Instrument development. The English version of the CDS was translated into Persian. A convenience sample of 140 (100 older people without dementia and 40 patients with dementia) Persian-speaking people were selected from the nursing homes in Ahvaz, Iran. Cronbach's alpha, discriminant validity, and construct validity (exploratory factor analysis) were examined. Exploratory factor analysis indicated that the CDS has two factors, including psychosocial and somatic factors. Discriminant validity showed that the CDS can differentiate patients with dementia from the older adults without dementia. The results of the study showed that the Persian CDS is a reliable and valid scale when used in nursing homes. The Persian version of the CDS can help clinicians and nurses to assess patients' need and the degree of care dependency among older adults in Persian-speaking areas.

    Nowadays, virtually everybody is exposed to radiofrequency radiation (RFR) from mobile phone base station antennas or other sources. At least according to some scientists, this exposure can have detrimental health effects. We investigated cytogenetic effects in peripheral blood lymphocytes from subjects who were professionally exposed to mobile phone electromagnetic fields in an attempt to demonstrate possible RFR-induced genetic effects. These subjects can be considered well suited for this purpose as their RFR exposure is 'normal' though rather high, and definitely higher than that of the 'general population'. The alkaline comet assay, sister chromatid exchange (SCE) and chromosome aberration tests revealed no evidence of RFR-induced genetic effects. Blood cells were also exposed to the well known chemical mutagen mitomycin C in order to investigate possible combined effects of RFR and the chemical. No cooperative action was found between the electromagnetic field exposure and the mutagen using either the comet assay or SCE test.

    Leiomyoma is the most common benign tumor of the pelvic that is associated with reproductive problems such as infertility, frequent abortions, and undesirable prenatal outcomes. High prevalence of leiomyoma and its relation with important gynecological complications, especially during reproductive ages, on the one hand, and high medical expenses and significant complications of common treatments, on the other, made us search traditional Persian medicine texts for a similar disease. In traditional Persian medicine, a condition has been introduced similar to leiomyoma (Oram-e-rahem). In this article, by collecting materials from traditional medicine texts on leiomyoma, we aim to provide theories for further studies on this topic, as there is an obvious difference between traditional Persian medicine and modern medicine with regard to leiomyoma. When modern medicine has not found a suitable response to treatment, reviewing of traditional Persian medicine for finding better treatment strategies is wise. © The Author(s) 2015.

    Current models of oral reading assume that different routes (sublexical, lexical, and semantic) mediate oral reading performance and reliance on different routes during oral reading depends on the characteristics of print to sound mappings. Studies of single cases of acquired dyslexia in aphasia have contributed to the development of such models by revealing patterns of double dissociation in object naming and oral reading skill that follow brain damage in Indo-European and Sino-Tibetan languages. Print to sound mapping in Persian varies in transparency because orthography to phonology translation depends uniquely on the presence or absence of vowel letters in print. Here a hypothesis is tested that oral reading in Persian requires a semantic reading pathway that is independent of a direct non-semantic reading pathway, by investigating whether Persian speakers with aphasia show selective impairments to object naming and reading aloud. A sample of 21 Persian speakers with aphasia ranging in age from 18 to 77 (mean = 53, SD = 16.9) was asked to name a same set of 200 objects and to read aloud the printed names of these objects in different sessions. As an additional measure of sublexical reading, patients were asked to read aloud 30 non-word stimuli. Results showed that oral reading is significantly more preserved than object naming in Persian speakers with aphasia. However, more preserved object naming than oral reading was also observed in some cases. There was a moderate positive correlation between picture naming and oral reading success (p Persian for the first time. © 2016 The British Psychological Society.

    Wars and injuries have accompanied mankind throughout history. Physicians and surgeons from various civilizations made difficult attempts to manage wounds and injuries. Among various civilizations, the Persian Empires had great armies which were well equipped. One of the most important organizations in Persian troops was the military surgery. This study presents a brief biography of Hakim Mohammad (a military surgeon in Safavid era) and introduces his book, Dhakhira-yi-Kamilah. Safavid kings (1501-1736 CE) with unifying all of Persian regions and provinces reconstructed the Persian Empire. Great scholars and physicians were raised in this era. It seems that Persian physicians and surgeons were well trained in Safavid era and many of them were even employed by other countries like Ottoman Empire and India. Hakim Mohammad as a military surgeon was one of such physicians who served in Ottoman Empire for some time. He gathered his surgical experiences and others in the book of Dhakhira-yi-Kamilah. This book was written in Persian. He has mainly written about the management of wounds and practical techniques. Later, he came back to his homeland and dedicated his book to the king of Persia.

    Full text: There are several reports of studies that suggest a causal association between exposure to ionizing radiation and the subsequent development of breast cancer. Since the Chernobyl accident in 1986, there has been a dramatic increase in thyroid cancer after radiation exposure, especially among those who were exposed as young children and living in the areas with the greatest contamination. One early report found that women exposed to radiation from Chernobyl had a slight, but significant increase in the incidence of breast cancer. No other data are reported about additional risks for the development of breast cancer in this population. With funding from a NIH R03 grant application and the Child Health International Foundation, we are investigating the molecular epidemiology of breast cancer in Belarusian women exposed at ages < 40 years to high radiation doses from the Chernobyl accident compared to controls for the common Eastern European BRCA 1/2 mutations. As occurred 20+ years after exposure of Japanese women exposed to radiation fallout from atomic bombs in 1945, we expect to find a sustained increase in breast cancer for the coming decade and longer. We accomplished nearly all of the following objectives in the evaluation of Belarusian women with breast cancer and controls who were exposed to sustained high doses of ionizing radiation in 1986. When our US collaborators visited the Republic of Belarus, they (a) met with Belarusian consultants, co-investigators, other health care professionals and administrators and developed a formal collaboration to study breast cancer, BRCA mutations and radiation exposure; (b) recruited Belarusian cancer epidemiologists, Chernobyl radiation dosimetrists, and cancer registry/database management personnel; (c) began a collaboration with the Director of Breast Cancer Surgery for the Republic of Belarus and met several breast cancer specialists in surgery and oncology under his direction; and (d) met medical directors

    Full Text Available In this paper, we present a new approach to offline OCR (optical character recognition for printed Persian subwords using wavelet packet transform. The proposed algorithm is used to extract font invariant and size invariant features from 87804 subwords of 4 fonts and 3 sizes. The feature vectors are compressed using PCA. The obtained feature vectors yield a pictorial dictionary for which an entry is the mean of each group that consists of the same subword with 4 fonts in 3 sizes. The sets of these features are congregated by combining them with the dot features for the recognition of printed Persian subwords. To evaluate the feature extraction results, this algorithm was tested on a set of 2000 subwords in printed Persian text documents. An encouraging recognition rate of 97.9% is got at subword level recognition.

    To study the genetic effects in children exposed to radiation in utero as a result of the Chornobyl nuclear power plant accident accounting the total radiation doses and equivalent radiation doses to the red bone marrow. Incidence of minor developmental anomalies was studied in children exposed to radiation in utero (study group) and in the control group (1144 subjects surveyed in total). Cytogenetic tests using the method of differential G-banding of chromosomes were conducted in 60 children of both study and control groups (10-12-year-olds) and repeatedly in 39 adolescents (15-17-year-olds). A direct correlation was found between the number of minor developmental anomalies and fetal dose of radiation, and a reverse one with fetal gestational age at the time of radiation exposure. Incidence of chromosomal damage in somatic cells of 10-12-year-old children exposed prenatally was associated with radiation dose to the red bone marrow. The repeated testing has revealed that an increased level of chromosomal aberrations was preserved in a third of adolescents. The persons exposed to ionizing radiation at prenatal period should be attributed to the group of carcinogenic risk due to persisting increased levels of chromosome damage.

    This study examined the association between parent and family reported history of non-PTSD mental illness (MI), PTSD specifically, and substance use problems, and participant clinical diagnosis of PTSD. Participants were drawn from the US Department of Veterans Affairs Mid-Atlantic Mental Illness Research, Education and Clinical Center (MIRECC) Post-Deployment Mental Health (PDMH) study (n = 3191), an ongoing multi-site cohort study of US Afghanistan and Iraq conflict era veterans. Participants who recalled a father history of PTSD had a 26-percentage point higher likelihood of meeting criteria for PTSD; while participants reporting any family history of PTSD had a 15-percentage point higher probability of endorsing symptoms consistent with PTSD. Mother history of substance use problems was associated with Veteran current PTSD, but results were sensitive to model specification. Current PTSD was not associated with family/parent history of non-PTSD mental illness, mother history of PTSD, or family/father history of substance use problems. Family history of PTSD may increase PTSD risk among veterans exposed to trauma, particularly when a father history is reported. Knowledge of family history could improve clinical decision-making for trauma-exposed individuals and allow for more effective targeting of programs and clinical services. Published by Elsevier B.V.

    Orthotics and Prosthetics User's Survey (OPUS) was developed to measure patient satisfaction in Prosthetic and Orthotic (P&O) field. To translate the satisfaction assessment module of OPUS (OPUS-SM) into Persian language (Persian OPUS-SM) and investigate its psychometric properties. For cross-cultural adaptation of the OPUS-SM, the guideline suggested by the World Health Organization was recruited. A sample of 116 Persian-speaking people who received P&O devices and services, participated in this study. During the first session, participants filled out the Persian OPUS-SM and the Visual Analog Scale (VAS) regarding their satisfaction from delivered devices and services. Drawing from the above sample of 116 participants, 41 participants retook the Persian OPUS-SM 5-7 days after their first time. The results of the first and second administration sessions were analyzed to assess internal consistency, test-retest reliability, item-subscale correlation, minimal detectable change, floor and ceiling effects, criterion validity, and dimensionality of the Persian OPUS-SM. The Cronbach's alphas of the Persian OPUS-SM were 0.71 and 0.89 for device and service satisfaction subscales, respectively. The intraclass correlation coefficients were 0.76 and 0.90 for device and service satisfaction subscales, respectively. The SEM and MDC for device satisfaction were 6.21 and ±17.21, respectively. The SEM and MDC for service satisfaction were 2.25 and ±6.22, respectively. There was a strong correlation between VAS and satisfaction subscales of the Persian OPUS-SM. Dimensionality assessment revealed that Persian OPUS-SM is a unidimensional measure. The adapted and translated Persian OPUS-SM is a reliable and validated measure. Copyright © 2016 Elsevier Inc.

    Oxford Elbow Score (OES) is a patient-reported questionnaire used to assess outcomes after elbow surgery. The aim of this study was to validate and adapt the OES into Persian language. After forward-backward translation of the OES into Persian, a total number of 92 patients after elbow surgeries completed the Persian OES along with the Persian DASH and SF-36. To assess test-retest reliability, 31 randomly selected patients (34%) completed the Persian OES again after three days while abstaining from all forms of therapeutic regimens. Reliability of the Persian OES was assessed by measuring intraclass correlation coefficient (ICC) for test-retest reliability and Cronbach's alpha for internal consistency. Spearman's correlation coefficient was used to test the construct validity. Cronbach's alpha coefficient was 0.92 showing excellent reliability. Cronbach's alpha for function, pain, and social-psychological subscales was 0.95, 0.86, and 0.85, respectively. Intraclass correlation coefficient (ICC) was 0.85 for the overall questionnaire and 0.90, 0.76, and 0.75 for function, pain, and social-psychological subscales, respectively. Construct validity was confirmed as the Spearman correlation between OES and DASH was 0.80. Persian OES is a valid and reliable patient-reported outcome measure to assess postsurgical elbow status in Persian speaking population.

    This study investigated the potential of Persian shallot extract as an anticancer agent in HepG2 tumor cell line, an in vitro human hepatoma cancer model system. The inhibitory effect of Persian shallot on the growth of HepG2 cells was measured by MTT assay. To explore the underlying mechanism of cell growth inhibition of Persian shallot, the activity of Persian shallot in inducing apoptosis was investigated through the detection of annexin V signal by flow cytometry and expression of some apoptosis related genes such p21, p53, puma, caspase-8 family-Bcl-2 proteins like bid, bim, bcl-2 and bax were measured by real-time PCR in HepG2 cells. Persian shallot extract inhibited the growth of HepG2 cells in a dose-dependent manner. The IC 50 value (inhibiting cell growth by 50%) was 149 μg/ml. The results of real-time PCR revealed a significant up-regulation of bid, bim, caspase-8, puma, p53, p21 and bax genes and a significant downregulation of bcl-2 gene in HepG2 cells treated with Persian shallot extract significantly. Therefore, this is the first report on an increased expression of bid, bim, caspase-8, puma, p53, p21 and bax genes and down regulation of bcl-2 gene indicating that the Persian shallot extract possibly induced the process of cell death through the intrinsic and extrinsic apoptosis pathways and triggers the programmed cell death in HepG2 tumor cell lines by modulating the expression of pro-/anti-apoptotic genes. Furthermore, we showed that Persian shallot extract increased annexin V signal and expression, resulting in apoptotic cell death of HepG2 cells after 24 h treatment. Therefore, according to the results of this study, the Persian shallot extract could be considered as a potential candidate for production of drug for the prevention or treatment of human hepatoma.

    The Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) formally introduced a dissociative subtype of posttraumatic stress disorder (PTSD). This study examined the proportion of U.S. veterans with DSM-5 PTSD that report dissociative symptoms; and compared veterans with PTSD with and without the dissociative subtype and trauma-exposed controls on sociodemographics, clinical characteristics, and quality of life. Multivariable analyses were conducted on a nationally representative sample of 1484 veterans from the National Health and Resilience in Veterans Study (second baseline survey conducted September-October, 2013). Of the 12.0% and 5.2% of veterans who screened positive for lifetime and past-month DSM-5 PTSD, 19.2% and 16.1% screened positive for the dissociative subtype, respectively. Among veterans with PTSD, those with the dissociative subtype reported more severe PTSD symptoms, comorbid depressive and anxiety symptoms, alcohol use problems, and hostility than those without the dissociative subtype. Adjusting for PTSD symptom severity, those with the dissociative subtype continued to report more depression and alcohol use problems. These results underscore the importance of assessing, monitoring, and treating the considerable proportion of veterans with PTSD and dissociative symptoms. Published by Elsevier Ltd.

    Following the Goiania radiation accident, lymphocytes from 110 exposed or potentially exposed individuals were analyzed for the frequencies of chromosomal aberrations (dicentrics and centric rings) to estimate absorbed radiation dose. Dose estimates for 21 subjects exceeded 1.0 Gy, and for eight subjects they exceeded 4.0 Gy. Four of the subjects died. After the emergency period, a cytogenetic follow-up of 10 of the highest exposed patients was started. The results suggest that the average disappearance half-time of lymphocytes containing dicentric and centric rings was 130 d, which is shorter than the usually accepted value of 3 y reported in the literature

    Full Text Available Abstract                                                                                           Caesura is a pause in a line of poetry that were used primarily in Greek poetry and moreover in the poetry of most indo- European languages: Latin, Sanskrit, Avestan, German and old English. Although in Persian prosody, Caesura has an important place critics have paid little attention to it and consequently, its relations with prosodic meter of Persian poetry remains unclear. In first view it seems that the main situation of caesuras in Persian prosody is between two hemistiches of line or in middle of hemistiches with cyclical (symmetrical meter but in this study we tried to observe other inter-hemistich caesuras. The principle question we follow is the functions of caesura in Persian prosodic poem. We tried to prove that caesura is rarely the basic element of meter and in most cases, its main assistant. Primarily, we recognized caesuras in two kinds of meter: meter with obligatory caesura (that caesura is the main factor of its rhythm and meter with voluntary caesura (that caesura is an assistant of its rhythm. Meter with obligatory caesura In prosodic Persian poetry, these meters are low usage and in order to their rhythm be heard, it is necessary to set caesuras strictly in proper place. It must notice that these meters, contrary to most of Persian prosodic ones, are not composed of two syllable types (long & short syllables. They are made exclusively of long syllables. It seems that caesura in this kind of meter, is replaced with short syllables and made possible to form syllabic ordered sets so these meters could be considered as a different kind of ordinary quantitative Persian prosodic meter.   Meter with voluntary caesura In this kind, Caesura is an assistant of meter and so, there is no obligation to pause at its place, however, on the one hand it

    Unscheduled DNA synthesis induced by 'in vitro' UV-irradiation was investigated in lymphocytes of persons occupationally exposed to low doses of ionizing radiation (maximum registered radiation dose: 98 mrad/month). For radiation exposures >14 mrad/month, above background level, increased rates of UDS after in vitro UV-irradiation of lymphocytes were found. The bromodeoxyuridine differential chromatid labeling technique was applied to the examination of spontaneous and mytomycin C induced sister chromatid exchanges in the same population. No statistically significant difference could be determined in spontaneously occurring SCEs, while MMC induced SCEs were significantly reduced in persons exposed to radiation doses >14 mrad/month, thus indicating increased repair capability for DNA lesions inflicted by a second insult after protracted low dose irradiation.

    Cardiovascular diseases are major health complications currently in various societies. Management of heart diseases as a prevention step or as treatment with low-cost procedures like lifestyle modifications including nutrition are important current trends. Although the term nutrition dates back to 2 past centuries, Persian physicians contributed to this term at least from 1000 years ago. Rhazes (865-925 AD) was one of the pioneers in this field. He preferred using foods in treating illnesses. "Foods and drinks" were 1 subject from 6 principles (Setteh Zarorieh) that Persian physicians believed can affect human health. In this review, we described some medieval Persian views on the role of nutrition in heart diseases and compare their prescriptions with current findings. Interestingly, current investigations mostly support Persian medicine principles. Historically, this work shows that the concept of nutrition in heart diseases has had a successful background at least from 1000 years ago in Persia. © The Author(s) 2014.

    The most common cognitive disorder that is disabling is dementia. During the medieval period, traditional Persian medicine was an outstanding source of medicine that was used as standard references in medical schools of in the West and Middle East. In ancient manuscripts of traditional Persian medicine, a condition has been introduced similar to dementi (raoonat and homgh). In this article, by collecting materials of traditional medicine texts on dementia, we aim to provide theories for further studies on this topics, as there is an obvious difference between traditional Persian medicine and modern medicine with regard to dementia; however, since modern medicine has not found a suitable response to treatment for all diseases, reviewing traditional Persian medicine for finding better treatment strategies is wise. Use of all medical potentials approved by the World Health Organization beside classic medicine like traditional medicine and considering the availability and acceptability among people is recommended. © The Author(s) 2015.

    A long-term genetic monitoring of the Goiania population exposed to ionizing radiation of Cesium-137 is described using cytogenetic and molecular endpoints. Two molecular methods were employed: the hprt clonal assay, involving in vitro selection of 6-thioguanine-resistant hprt mutant clones which were characterized at the molecular level using RT-PCR and genomic analysis. Ionizing radiation exposure initially elevated hprt mutation frequency which gradually diminished, so that no significant increase was observed 4.5 years after original exposure. The spectrum of hprt mutation recovered from 10 individuals exposed to relatively high doses of radiation revealed a 4-fold increase in the frequency of A:T{yields}G:C transitions. Additionally, a two-fold increase in the frequency of deletions was observed which may reflect radiation-induced DNA strand breakage; determination of micro satellite instability using fluorescent PCR and genomic DNA from mononuclear cells. The frequency distribution of somatic micro satellite alterations in exposed and non-exposed populations were not different. We estimated the risk associated with radiation exposure for the exposed Goiania population. The estimated genetic risk of dominant disorders in the first post-exposure generation was increased by approximately a 24-fold. The risk of carcinogenesis was increased by a factor of 1.5 13 refs.; e-mail: acruz at uvic.ca.; bwglick at uvic.ca

    Full Text Available BACKGROUND: The Chernobyl accident represents a long-term experiment on the effects of exposure to ionizing radiation at the ecosystem level. Though studies of these effects on plants and animals are abundant, the study of how Chernobyl radiation levels affect prokaryotic and eukaryotic microbial communities is practically non-existent, except for a few reports on human pathogens or soil microorganisms. Environments enduring extreme desiccation and UV radiation, such as sunlight exposed biofilms could in principle select for organisms highly resistant to ionizing radiation as well. METHODOLOGY/PRINCIPAL FINDINGS: To test this hypothesis, we explored the diversity of microorganisms belonging to the three domains of life by cultivation-independent approaches in biofilms developing on concrete walls or pillars in the Chernobyl area exposed to different levels of radiation, and we compared them with a similar biofilm from a non-irradiated site in Northern Ireland. Actinobacteria, Alphaproteobacteria, Bacteroidetes, Acidobacteria and Deinococcales were the most consistently detected bacterial groups, whereas green algae (Chlorophyta and ascomycete fungi (Ascomycota dominated within the eukaryotes. Close relatives to the most radio-resistant organisms known, including Rubrobacter species, Deinococcales and melanized ascomycete fungi were always detected. The diversity of bacteria and eukaryotes found in the most highly irradiated samples was comparable to that of less irradiated Chernobyl sites and Northern Ireland. However, the study of mutation frequencies in non-coding ITS regions versus SSU rRNA genes in members of a same actinobacterial operational taxonomic unit (OTU present in Chernobyl samples and Northern Ireland showed a positive correlation between increased radiation and mutation rates.

    The Dysphagia Handicap Index (DHI) is one of the instruments used for measuring a dysphagic patient's self-assessment. In some ways, it reflects the patient's quality of life. Although it has been recognized and widely applied in English speaking populations, it has not been used in its present forms in Persian speaking countries. The purpose of this study was to adapt a Persian version of the DHI and to evaluate its validity, consistency, and reliability in the Persian population with oropharyngeal dysphagia. Some stages for cross-cultural adaptation were performed, which consisted in translation, synthesis, back translation, review by an expert committee, and final proof reading. The generated Persian DHI was administered to 85 patients with oropharyngeal dysphagia and 89 control subjects at Zahedan city between May 2013 and August 2013. The patients and control subjects answered the same questionnaire 2 weeks later to verify the test-retest reliability. Internal consistency and test-retest reliability were evaluated. The results of the patients and the control group were compared. The Persian DHI showed good internal consistency (Cronbach's alpha coefficients range from 0.82 to 0.94). Also, good test-retest reliability was found for the total scores of the Persian DHI (r=0.89). There was a significant difference between the DHI scores of the control group and those of the oropharyngeal dysphagia group (P‹0.001). The Persian version of the DHI achieved Face and translation validity. This study demonstrated that the Persian DHI is a valid tool for self-assessment of the handicapping effects of dysphagia on the physical, functional, and emotional aspects of patient life and can be a useful tool for screening and treatment planning for the Persian-speaking dysphagic patients, regardless of the cause or the severity of the dysphagia.

    Full text: Frequencies of chromosomal aberrations in lymphocytes of peripheral blood were investigated among the observed groups of subjects who were exposed to low radiation doses (external exposure) in comparison with the control group. The first group of subjects is involved in the production of radioisotope technetium, whose accumulated work exposure time ranges between 3 and 30 years. The second group works on inspection of the medical X-ray equipment, whose accumulated work exposure time is between 2 and 34 years. The third group worked on decontamination of the terrain from depleted uranium radioactive ammunition. These workers were involved in mechanical removal of the surface soil layer to a depth of 50 cm. They were selected out of a group of professionals otherwise exposed to radiation from confined sources in their daily work. The accumulated work exposure of this group ranged from 2 to 34 years. The control group consisted of individuals not working in the ionizing radiation zone. The average yearly absorbed dose measured by TL dosimeters for all three observed groups did not exceed 2 mSv. The chromosomal aberrations were analyzed by a modified Moorhead method. The objective of the study was to establish the existence of differences in the frequencies of chromosomal aberrations change with respect to the source type, i.e. type of radioactive emission. Comparisons of the chromosomal changes in the observed groups revealed that the group working on technetium production had an increase in the frequency of chromosomal aberrations with respect to control. The aberrations found were of the acentric fragment and chromosomal break types. A comparison of the exposed groups between each other, no statistically significant differences in the numbers of chromosomal aberrations were found. Soil decontamination from depleted uranium did not contribute to the relative radiation risk, since it lasted only a few months, and was done by the professionals fully clothed

    Oxford shoulder score is a specific 12-item patient-reported tool for evaluation of patients with inflammatory and degenerative disorders of the shoulder. Since its introduction, it has been translated and culturally adapted in some Western and Eastern countries. The aim of this study was to translate the Oxford Shoulder Score (OSS) in Persian and to test its validity and reliability in Persian speaking population in Iran. One hundred patients with degenerative or inflammatory shoulder problem participated in the survey in 2012. All patients completed the Persian version of OSS, Persian DASH and the SF-36 for testing validity. Randomly, 37 patients filled out the Persian OSS again three days after the initial visit to assess the reliability of the questionnaire. Cronbach's alpha coefficient was 0.93. The intraclass correlation coefficient was 0.93. In terms of validity, there was a significant correlation between the Persian OSS and DASH and SF-36 scores (P Persian version of the OSS proved to be a valid, reliable, and reproducible tool as demonstrated by high Cronbach's alpha and Pearson's correlation coefficients. The Persian transcript of OSS is administrable to Persian speaking patients with shoulder condition and it is understandable by them.

    In physico-chemical interaction with cellular DNA ionizing radiation produces a variety of primary lesions, such as single-strand breaks (SSB), alkali-labile sites, double-strand breaks (DSB), DNA-DNA and DNA-protein crosslinks, and damage to purine and pyrimidine bases. The effects of low-level exposure to ionising radiation are of concern to large number of people, including workers receiving radiation exposure on the job. It is very important to estimate absorbed doses from individuals occupationally exposed to ionising radiation for carrying out radioprotection procedures and restrict the hazards to human health. A wide range of methods is presently used for the detection of early biological effects of DNA-damaging agents in environmental and occupational settings. Currently, unstable chromosomal aberrations in peripheral blood lymphocytes, in particularly dicentrics, are the most fully developed biological indicators of ionizing radiation exposure. This methodology usually complements data obtained by physical dosimetry. As a routine, it is used whenever the individual dosimeter shows an exposure to penetrating radiation above its limit of detection. One of the advantages of cytogenetic dosimetry is that this biological dosimeter can be assessed at any moment whereas physical dosimeters are not always present in the subject. During the last years, the single cell gel electrophoresis (SCGE) or comet assay has gained widespread acceptance for genotoxicity testing. In molecular epidemiology studies DNA damage evaluated by the comet assay is utilized as a biomarker of exposure. The comet assay permits the detection of primary DNA damage and the study of repair kinetics at the level of single cells. The aim of the present study was to assess and quantificate the levels of DNA damage in peripheral blood leukocytes of medical workers occupationally exposed to ionizing radiation and corresponding unexposed control subjects. As a sensitive biomarker of exposure the

  17. The management of workers occupationally exposed to ionizing radiation

    In Canada, the regulation of radiation protection is a shared responsibility between the federal body (the Atomic Energy Control Board) and the appropriate provincial body (usually the Department of Health, or Department of Labour). The AECB is responsible, for example, for regulating the development, application and use of nuclear energy and radioisotopes, and the provinces are responsible for the regulation of all other forms of ionizing and non-ionizing radiations and for naturally-occurring radioactive material (NORM). Although there is consultation between the federal and provincial regulatory agencies, the division of jurisdictional authority has resulted in considerable differences in the approach towards implementation radiation protection programs in Canada. This is especially true in the management of workers occupationally exposed to ionizing radiation. These differences have produced unwarranted discrepancies in operating procedures and practices in the allocation of resources and manpower, and in the requirements governing radiological training, personnel monitoring and medical surveillance. In light of the General Amendments to the AEC Regulations, the 1990 Recommendations of the ICRP, and the IAEA recommendations on safety culture, the ACRP has considered it timely to undertake a study to examine the feasibility of establishing a more coherent approach to harmonize radiation protection practices within Canada. This study comprised an examination of the regulatory approach used in several countries: a review of the nature of radiation safety programs in various types of licensed institutions and facilities in Canada; and a review of recommendations of internationally-recognized authorities in radiation protection

    Cytogenetic assays for unstable chromosomes were performed on 54 medical radiation workers who are occupationally exposed to radiation and 42 controls. A total of 15,577 metaphase cells were scored. The frequencies of dicentrics and acentric chromosomes on controls were 0.52*10{sup -3} and 0.82*10{sup -2}, respectively. On radiation workers those were 2.28*10{sup -3} and 1.34*10{sup -2}, respectively. Though the frequencies of all types of chromosome aberrations in the workers were higher than those in the controls, the only significant difference was found in the case of dicentrics (P < 0.01). When we considered exposure dose of recent one year, duration of employment and smoking habit in radiation worker, a slight increase was shown in frequency of unstable chromosome aberrations on these workers, but no statistical differences were observed (P > 0.05) except exposure dose of recent one year (P < 0.05). These results could indicate that low level exposure to ionizing radiation can induce unstable chromosome aberrations in blood lymphocytes.

    Cognitive impairment in patients with Parkinson's disease (PD) mainly involves executive function (EF). The frontal assessment battery (FAB) is an efficient tool for the assessment of EFs. The aims of this study were to determine the validity and reliability of the psychometric properties of the Persian version of FAB and assess its correlation with formal measures of EFs to provide normative data for the Persian version of FAB in patients with PD. The study recruited 149 healthy participants and 49 patients with idiopathic PD. In PD patients, FAB results were compared to their performance on EF tests. Reliability analysis involved test-retest reliability and internal consistency, whereas validity analysis involved convergent validity approach. FAB scores compared in normal controls and in PD patients matched for age, education, and Mini-Mental State Examination (MMSE) score. In PD patients, FAB scores were significantly decreased compared to normal controls, and correlated with Stroop test and Wisconsin Card Sorting Test (WCST). In healthy subjects, FAB scores varied according to the age, education, and MMSE. In the FAB subtest analysis, the performances of PD patients were worse than the healthy participants on similarities, fluency tasks, and Luria's motor series. Persian version of FAB could be used as a reliable scale for the assessment of frontal lobe functions in Iranian patients with PD. Furthermore, normative data provided for the Persian version of this test improve the accuracy and confidence in the clinical application of the FAB.

    Acute or chronic exposure to ionizing radiation is a factor that may be hazardous to health. It has been reported that exposure to low doses of radiation (less than 50 mSv / year) and subsequently exposure to high doses have greater effects in people. However, it is unknown molecular and biochemical level alteration. This study, analyzes the susceptibility of a biological system (HeLa Atcc CCL-2 human cervix cancer cell line) to ionizing radiation (6 and 60 mSv/ 90). Our evaluate multiple variables such as: total protein profile, mitochondrial metabolic activity (XTT assay), cell viability (Trypan blue exclusion assay), cytoskeleton (actin micro filaments), nuclei (D API), genomic DNA. The results indicate, that cells exposed to ionizing radiation structurally show alterations in nuclear phenotype and aneuploidy, further disruption in the tight junctions and consequently on the distribution of actin micro filaments. Similar alterations were observed in cells treated with a genotoxic agent (200μM H 2 O 2 /1 h). In conclusion, this multi-criteria assessment enables precise comparisons of the effects of radiation between any biological systems. However, it is necessary to determine stress markers for integration of the effects of ionizing radiation. (Author)

    Acute or chronic exposure to ionizing radiation is a factor that may be hazardous to health. It has been reported that exposure to low doses of radiation (less than 50 mSv / year) and subsequently exposure to high doses have greater effects in people. However, it is unknown molecular and biochemical level alteration. This study, analyzes the susceptibility of a biological system (HeLa Atcc CCL-2 human cervix cancer cell line) to ionizing radiation (6 and 60 mSv/ 90). Our evaluate multiple variables such as: total protein profile, mitochondrial metabolic activity (XTT assay), cell viability (Trypan blue exclusion assay), cytoskeleton (actin micro filaments), nuclei (D API), genomic DNA. The results indicate, that cells exposed to ionizing radiation structurally show alterations in nuclear phenotype and aneuploidy, further disruption in the tight junctions and consequently on the distribution of actin micro filaments. Similar alterations were observed in cells treated with a genotoxic agent (200μM H{sub 2}O{sub 2}/1 h). In conclusion, this multi-criteria assessment enables precise comparisons of the effects of radiation between any biological systems. However, it is necessary to determine stress markers for integration of the effects of ionizing radiation. (Author)

    The ability of cells to adapt low-dose or low-dose rate radiation is well known. High-LET radiation has unique characteristics, and the data concerning low doses effects and high-LET radiation remain fragmented. In this study, we assessed in vitro the ability of low doses of X-rays to induce an adaptive response (AR) to a subsequent challenging dose of heavy-ion radiation. Lymphoblastoid cells (TK6, AHH-1, NH32) were exposed to priming 0.02-0.1Gy X-rays, followed 6h later by challenging 1Gy heavy-ion radiation (carbon-ion: 20 and 40keV/μm, neon-ion: 150keV/μm). Pre-exposure of p53-competent cells resulted in decreased mutation frequencies at hypoxanthine-guanine phosphoribosyl transferase locus and different H2AX phosphorylation kinetics, as compared to cells exposed to challenging radiation alone. This phenomenon did not seem to be linked with cell cycle effects or radiation-induced apoptosis. Taken together, our results suggested the existence of an AR to mutagenic effects of heavy-ion radiation in lymphoblastoid cells and the involvement of double-strand break repair mechanisms.

    Persian shallot grows as a wild plant in some mountains of Iran, The aim of our research was to study the relationship between different temperatures, seed age and duration of sulfuric acid treatment on Persian shallot seed germination. The interactive effect of incubation temperature, seed age and scarification treatments had a significant effect on the germination and emergence percentage of Persian shallot. It is concluded that suitable condition for Persian shallot seed germination is scarification of one year old seeds with sulfuric acid for 15 min, and stratification at 4 deg. C. In fact Persian shallot seeds need both scarification and stratification for germination enhancement. (author)

    The purpose of the present study was to investigate associations between the 7-factor hybrid model of DSM-5 posttraumatic stress disorder (PTSD) symptoms, which includes intrusions, avoidance, negative affect, anhedonia, externalizing behaviors, anxious arousal, and dysphoric arousal symptoms, and alcohol consumption and consequences. A nationally representative sample of 916 trauma-exposed U.S. military veterans were administered the Trauma History Screen, PTSD Checklist-5, and Alcohol Use Disorders Identification Test. Confirmatory factor analyses were conducted to determine associations between the 7-factor hybrid model of PTSD symptoms, and alcohol consumption and consequences. Results revealed that lifetime dysphoric arousal (r=0.31), negative affect (r=0.30), and anhedonia (r=0.29) symptom clusters were most strongly associated with past-year alcohol consequences. No significant associations were observed for alcohol consumption. While the cross-sectional study design does not allow one to ascertain causative associations between PTSD factors and alcohol consumption and consequences, results generally align with the self-medication hypothesis, as PTSD factors reflecting internalizing were most strongly related to alcohol-related consequences. These results underscore the importance of assessing for alcohol use problems in veterans who score highly on PTSD symptoms reflecting internalizing symptomatology. Copyright © 2017 Elsevier Ltd.

    Full Text Available Abstract Poetic return movement was started by a group of poets like Moshtagh and Shole Esfehani in the second half of 12 century. Their goal was restoring Persian poem and deliverance of Hindi style decline. Esfahan’s poets initiative was considered only in Iran but in other Persian language and literature areas like India, Afghanistan and Transoxiana it was ignored. After the failure of constitutional Movement in Afghanistan, motion similar poetic return was happened that caused poetic themes, which had gone towards modernism, return to Hindi style again.The present paper attempts to analyze the poetic atmosphere in Afghanistan synchronous the poetic return movement in Iran and investigate socio- political backgrounds of return to Hindi style in Afghanistan after constitution failure.

    Studies of occupational populations exposed to large doses of radiation, principally from the ingestion of radium by dial painters and inhalation of radon and its daughters by miners, have provided important information on the health effects of those radioisotopes. Studies of medical radiologists, military personnel exposed to nuclear tests, and factory workers exposed to thorium are in progress. Employees of DOE-contractor facilities and of naval shipyards are also under study. Personnel dosimetry data are generally available for the latter category of occupational populations. Reasons for conducting the studies include interest in exploring the verification at low exposure levels of results of studies of heavily exposed populations and the responsibility of the employer to maintain adequate surveillance of the health of his workers by conducting appropriate epidemiologic studies. The low level of exposure of workers in facilities where adequate personnel dosimetry records are available make it unlikely that the results of such studies can be used to provide health risk estimates in the near future

    Subjects occupationally exposed to ionizing radiation (external exposition) are examined for chromosomal aberrations in peripheral blood lymphocytes in comparison to a control group. The average annual absorbed dose, measured by TLD dosimeters, for all three groups did not exceed 2mSv. Continuous exposure to small doses of ionizing radiation causes unstable aberrations in lymphocytes. In this research the largest number of found alterations are of acentric fragments and chromosomal breaks type. The highest occupational risk appears to be for subjects working in manufacturing of radio isotope technetium [sr

    Background: A small group of Gulf War I veterans wounded in depleted uranium (DU) friendly-fire incidents have been monitored for health changes in a clinical surveillance program at the Veterans Affairs Medical Center, Baltimore since 1994. Methods: During the spring of 2015, an in-patient clinical surveillance protocol was performed on 36 members of the cohort, including exposure monitoring for total and isotopic uranium concentrations in urine and a comprehensive assessment of health outcomes. Results: On-going mobilization of U from embedded fragments is evidenced by elevated urine U concentrations. The DU isotopic signature is observed principally in participants possessing embedded fragments. Those with only an inhalation exposure have lower urine U concentration and a natural isotopic signature. Conclusions: At 25 years since first exposure to DU, an aging cohort of military veterans continues to show no U-related health effects in known target organs of U toxicity. As U body burden continues to accrue from in-situ mobilization from metal fragment depots, and increases with exposure duration, critical tissue-specific U concentration thresholds may be reached, thus recommending on-going surveillance of this veteran cohort. - Highlights: • Gulf War I veterans wounded with depleted uranium are monitored for health changes. • In 2015 in-patient clinical surveillance was performed on 36 members of the cohort. • Mobilization of U from embedded fragments is evidenced by elevated U in urine. • This cohort of continues to show no U-related health effects.

  12. Blast Exposure, White Matter Integrity, and Cognitive Function in Iraq and Afghanistan Combat Veterans

    Full Text Available The long-term effects of blast exposure are a major health concern for combat veterans returning from the recent conflicts in Iraq and Afghanistan. We used an optimized diffusion tensor imaging tractography algorithm to assess white matter (WM fractional anisotropy (FA in blast-exposed Iraq and Afghanistan veterans (n = 40 scanned on average 3.7 years after deployment/trauma exposure. Veterans diagnosed with a blast-related mild traumatic brain injury (mTBI were compared to combat veterans with blast exposure but no TBI diagnosis. Blast exposure was associated with decreased FA in several WM tracts. However, total blast exposure did not correlate well with neuropsychological testing performance and there were no differences in FA based on mTBI diagnosis. Yet, veterans with mTBI performed worse on every neurocognitive test administered. Multiple linear regression across all blast-exposed veterans using a six-factor prediction model indicated that the amount of blast exposure accounted for 11–15% of the variability in composite FA scores such that as blast exposure increased, FA decreased. Education accounted for 10% of the variability in composite FA scores and 25–32% of FA variability in the right cingulum, such that as level of education increased, FA increased. Total blast exposure, age, and education were significant predictors of FA in the left cingulum. We did not find any effect of post-traumatic stress disorder on cognition or composite FA. In summary, our findings suggest that greater total blast exposure is a contributing factor to poor WM integrity. While FA was not associated with neurocognitive performance, we hypothesize that FA changes in the cingulum in veterans with multiple combat exposures and no head trauma prior to deployment may represent a marker of vulnerability for future deficits. Future work needs to examine this longitudinally.

    Finding the right word is a necessity in communication, and its evaluation has always been a challenging clinical issue, suggesting the need for valid and reliable measurements. The Homophone Meaning Generation Test (HMGT) can measure the ability to switch between verbal concepts, which is required in word retrieval. The purpose of this study was to adapt and validate the Persian version of the HMGT. The first phase involved the adaptation of the HMGT to the Persian language. The second phase concerned the psychometric testing. The word-finding performance was assessed in 90 Persian-speaking healthy individuals (20-50 year old; 45 males and 45 females) through three naming tasks: Semantic Fluency, Phonemic Fluency, and Homophone Meaning Generation Test. The participants had no history of neurological or psychiatric diseases, alcohol abuse, severe depression, or history of speech, language, or learning problems. The internal consistency coefficient was larger than 0.8 for all the items with a total Cronbach's alpha of 0.80. Interrater and intrarater reliability were also excellent. The validity of all items was above 0.77, and the content validity index (0.99) was appropriate. The Persian HMGT had strong convergent validity with semantic and phonemic switching and adequate divergent validity with semantic and phonemic clustering. The Persian version of the Homophone Meaning Generation Test is an appropriate, valid, and reliable test to evaluate the ability to switch between verbal concepts in the assessment of word-finding performance.

    Diagnostic radiology plays an important role in the assessment and treatment of neonates requiring intensive care. It is often necessary to perform multiple radiographic examinations depending upon the infants birth weight, gestational age and respiratory problems, especially to those infants with very low birth weight (< 1500g). The high frequency of these examinations raises the radiological issue due to the potentially long-term adverse effects. We hypothesize that unnecessary organs of those infants are exposed to X-ray radiation during their hospitalization, leading to an increased risk of long-term adverse effects. The goal of this study was to examine if organs, other than those originally intended, were exposed to excessive radiation in a population of neonates during their stay in the Neonatal Intensive Care Unit - NICU

    Full Text Available Abstract Diversity of suffix ‘-i’, called ‘ya’, in Persian language, which is of important consideration, for any reason, has not been able to attract scholars and grammarians in the field of Persian language. Here is an attempt to mention different kinds of ‘ya’ and to explain their applications, relying on grammar books, dictionaries, and today native application. The character generally has three types of applications in Persian language. It is firstly one of the Persian alphabet, so it primarily functions as a ‘phoneme’. It is applied in its second function when appears in the form of ’morpheme’, such as ‘-i’ in ‘mardi rad shod’ (a man passed with usage of indefinite article. The third function appears when it comes in the place of a word, because it is one of the six types of pronouns. So, ‘ya’ is applied in three forms: phoneme, morpheme and word. In continue, it is attempted to explain these kinds in more details. ‘ya’ as indefinite maker (Nakare: This kind of ‘ya’ is called the mark of indefinite by many of the Persian grammarians, including doctor Mohammad Moin. Dehkhoda says ‘ya’ is added to the end of the word to make it an indefinite one, such as the last word and it is a sign of indefinite types " of " is unknown, such as‘-i’ in ‘pesari ra didam’ (I saw a boy. ‘ya’ as numerical suffix means one (vahdat:  This kind is added to the last  of the word, and means "one". The difference between this one and the previous, ‘ya’ as indefinite maker, is just in their meanings. ‘ya’ as attributive suffix: This ‘ya’ is joined by various kinds of Persian words an attributes them to someone, some place or something, such as ‘Shirazi’(from shiraz, ‘farsi’(Persian, ‘Irani’(Iraian, Barmaki (Barmakian.

    The purpose was to study the risk factors and clinical course of brain strokes in professionally exposed workers being employed in plutonium production in comparison with a control group. The method and materials of study -clinical supervision and clinical database creation on 162 cases of brain stroke (128 males and 34 females) developed among professionally exposed workers. Age of patient varied from 21 to 68 years (in average -51.6 y.). The control group consisted of patients with the same diagnosis, worked on the same enterprise, but non-exposed to radiation. Data on the totally accumulated dose of external gamma radiation were received on the base of the individual dosimeters (from 0.1 cSv to 52 cSv, in average about 13 cSv); the plutonium-239 body content was estimated accordingly to the level of urine radionuclide excretion (from 0.4 kBq to 1.6 kBq, in average about 0.33 kBq). Muscle's hypertinsion and pathological great-toe reflexes in paretic legs and hands, hemianopsia, impressive and ataxic aphasia prevailed in the patients with ischemic brain strokes in system of internal carotid artery, exposed to radiation. The changes of muscle's tension, ataxia and nystagmus were marked more often in the professionals with ischemic brain strokes in system of vertebrobasilar artery. The illness proceeded more easy and with smaller frequency of frustration of consciousness and algesthesia, irrespective of a type ischemic brain strokes in the people exposed to ionizing radiation, than in patients of non-irradiated group. It was found that the arterial hypertension appeared to be the main risk factor for the brain stroke in both groups of patients (in 81.48% and 91.15% of cases). There was no marked differences in significance of risk factors and in main clinical parameters of various types of ischemic brain strokes among the patients professionally exposed to radiation in comparison with a control group.

    The Brazilian radiological accident that occurred in 1987, in Goiania, it was a terrible radiation episode. As a consequence, hundreds of people were contaminated due to the Cesium-137 radiation. Recently, many studies had shown that genome instabilities, such as, mutations, chromosomal aberrations, micronuclei formation and micro satellite instability and a delay on cellular death are usually reported on mammal cells exposed to ionizing radiation, being considered as a manly risk to humans. Mutations can be spontaneous, and the occurrence is dependent on the organism, or, induced, being associated to mutagenic exposition. Ionizing radiations are an example of physical and mutagenic agents that could harm the cell repair and could cause the development of many types of cancer. The evaluation of the biological effects of the ionizing radiation, in somatic and germ line cells, with a consequent determination of the radio-induced mutations, it is extremely important to estimate the genetic risks, manly in population exposed to radiation. The analyses of repetitive DNA sequences have been demonstrated that such sequences are prone to high rates of spontaneous mutations. The minisatellites and microsatellites have been used to demonstrate the induction of germ line mutation rates on mouse, humans, among others organisms. The aim of the present study was to analyze the frequency of microsatellite alterations to determine the mutation rates occurred in germ cells of the parents exposed to the ionizing radiation of the Cesium-137. The studied group was constitute of 10 families of individuals accidentally exposed to Cesium-137 and by the control group constituted by 645 healthy individuals who carried out paternity tests on 2009. We found only one mutation of paternal origin in the D8S1179 locus on the exposed group, being the mutation rate of 0.002. In the control group, we found 01 mutation on D16S539 loei and on D3S1358; 02 mutations on Penta E loeus; 04 mutations on D

    Full Text Available Abstract                                                                                           Caesura is a pause in a line of poetry that were used primarily in Greek poetry and moreover in the poetry of most indo- European languages: Latin, Sanskrit, Avestan, German and old English. Although in Persian prosody, Caesura has an important place critics have paid little attention to it and consequently, its relations with prosodic meter of Persian poetry remains unclear. In first view it seems that the main situation of caesuras in Persian prosody is between two hemistiches of line or in middle of hemistiches with cyclical (symmetrical meter but in this study we tried to observe other inter-hemistich caesuras. The principle question we follow is the functions of caesura in Persian prosodic poem. We tried to prove that caesura is rarely the basic element of meter and in most cases, its main assistant. Primarily, we recognized caesuras in two kinds of meter: meter with obligatory caesura (that caesura is the main factor of its rhythm and meter with voluntary caesura (that caesura is an assistant of its rhythm. Meter with obligatory caesura In prosodic Persian poetry, these meters are low usage and in order to their rhythm be heard, it is necessary to set caesuras strictly in proper place. It must notice that these meters, contrary to most of Persian prosodic ones, are not composed of two syllable types (long & short syllables. They are made exclusively of long syllables. It seems that caesura in this kind of meter, is replaced with short syllables and made possible to form syllabic ordered sets so these meters could be considered as a different kind of ordinary quantitative

    Serum dioxin studies of Vietnam (VN) veterans, military historical records of tactical herbicide use in Vietnam, and the compelling evidence of the photodegradation of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and other aspects of environmental fate and low bioavailability of TCDD are consistent with few, if any, ground troop veterans being exposed to Agent Orange. That conclusion, however, is contrary to the presumption by the Department of Veterans Affairs (DVA) that military service in Vietnam anytime from January 9, 1962 to May 7, 1975 is a proxy for exposure to Agent Orange. The DVA assumption is inconsistent with the scientific principles governing determinations of disease causation. The DVA has nonetheless awarded Agent Orange-related benefits and compensation to an increasing number of VN veterans based on the presumption of exposure and the published findings of the Institute of Medicine that there is sufficient evidence of a "statistical association" (a less stringent standard than "causal relationship") between exposure to tactical herbicides or TCDD and 15 different human diseases. A fairer and more valid approach for VN veterans would have been to enact a program of "Vietnam experience" benefits for those seriously ill, rather than benefits based on the dubious premise of injuries caused by Agent Orange.

    Past research suggests that rates of trauma exposure and Posttraumatic Stress Disorder (PTSD) are elevated among lesbian, gay, bisexual, and transgender (LGBT) veterans compared to heterosexual and cisgender veterans. Given higher rates of trauma exposure and PTSD, and the culture associated with the Department of Defense's history of policies excluding LGBT people, it is important to understand if LGBT veterans are seeking PTSD treatment following discrimination-based traumatic events, where they seek care, and if they are satisfied with treatment. This study aimed to describe the experiences of discrimination-based trauma-exposed LGBT veterans' (n = 47) experiences with PTSD treatment, including location of treatment (Veterans Health Administration [VHA] versus non-VHA) and satisfaction with care. The majority of veterans had received a PTSD diagnosis from a health-care provider in their lifetimes (78.72%, n = 37), and over half reported currently experiencing PTSD symptoms. Approximately 47% of LGBT veterans with discrimination-based trauma histories preferred to seek PTSD treatment exclusively at VHA (46.81%) or with a combination of VHA and non-VHA services (38.30%). Veterans who received PTSD treatment exclusively from VHA reported higher satisfaction ratings (7.44 on 0-9 scale) than veterans who received PTSD treatment exclusively from outside VHA (5.25 on 0-9 scale). For veterans who sought PTSD treatment at both VHA and non-VHA facilities, there were no significant differences regarding satisfaction ratings for their PTSD treatment in the two settings. Results are discussed in terms of VHA's continued efforts to establish equitable, patient-centered health care for all veterans and the importance of non-VHA facilities to recognize veteran identities.

    The National Health System implemented in the last few years a new pattern of primary attention for workers by creating doctors offices in work centers. At the same time, the Ministry of Public Health (MINSAP) carries the medical surveillance of the staff exposed to ionizing radiation. This work proposes a program to integrate the consulting room on radiation hygiene to primary health care services for workers that work with ionizing radiation sources, aiming to ameliorate and improve them

    While a high-dose of ionizing radiation is generally harmful and causes damage to living organisms, a low-dose of radiation has been shown to be beneficial in a variety of animal models. To understand the basis for the effect of low-dose radiation in vivo, we examined the cellular and immunological changes evoked in mice exposed to low-dose radiation at very low (0.7 mGy/h) and low (3.95 mGy/h) dose rate for the total dose of 0.2 and 2 Gy, respectively. Mice exposed to low-dose radiation, either at very low- or low-dose rate, demonstrated normal range of body weight and complete blood counts. Likewise, the number and percentage of peripheral lymphocyte populations, CD4{sup +} T, CD8{sup +} T, B, or NK cells, stayed unchanged following irradiation. Nonetheless, the sera from these mice exhibited elevated levels of IL-3, IL-4, leptin, MCP-1, MCP-5, MIP-1{alpha}, thrombopoietin, and VEGF along with slight reduction of IL-12p70, IL-13, IL-17, and IFN-{gamma}. This pattern of cytokine release suggests the stimulation of innate immunity facilitating myeloid differentiation and activation while suppressing pro-inflammatory responses and promoting differentiation of naive T cells into T-helper 2, not T-helper 1, types. Collectively, our data highlight the subtle changes of cytokine milieu by chronic low-dose {gamma}-radiation, which may be associated with the functional benefits observed in various experimental models.

    Use of reliable screening and diagnostic tests for assessment of cognitive abilities in neurological patients is rapidly increasing in clinical practice. This is due to the increase in the prevalence of dementias and the raised awareness of cognitive impairment in neurological disorders. Two well-known bedside screening tests for dementias among the English-speaking population are the Mini Mental State Examination (MMSE) and Addenbrooke's Cognitive Examination (ACE). However, such tests have not been developed for the Persian-speaking population, which is estimated at 120 million worldwide. In this study we developed the Persian ACE and MMSE, adopted from the English version. We also assessed the sensitivity and specificity of these tests in the identification of Alzheimer's disease (AD) and mild cognitive impairment (MCI). We found that the Persian ACE at a cutoff point of 84, has a sensitivity of 93% and a specificity of 91% in discriminating MCI from a normal population; at 78, the test has a sensitivity of 73% and a specificity of 93% in differentiating MCI from AD, and at a similar cutoff point has a sensitivity of 100% and specificity of 96% in discriminating AD from a normal population. We conclude that the Persian ACE is a valuable tool in clinical practice in the Persian-speaking population. 2009 S. Karger AG, Basel.

    The operation of nuclear power plants is always subjected to emission of some radioactive materials in the form of gaseous, liquids and solids in the environment. The heat from condenser coolant discharged to the sea can have some adverse effects on biological systems as thermal pollution. In this project, the radiation and thermal effects on Bushehr Nuclear Power Plants on aquatic animals in Persian Gulf were studied. The mathematical models for atmospheric dispersion of pollutant and pathways of radioactive materials from air to sea water and from sea to animals and human bodies were considered. some environmental samples from Persian Gulf were measured for radioactivity using high-purity Ge/Li detectors and Gamma-spectroscopy. The results indicates that the erection of B usher Nuclear Power Plants and its operation in the normal operation can have no adverse effects on environment, and also its thermal pollution is of no importance due to low area for coolant discharges

    Immunomodulatory effects of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) demonstrated using animals are thymic atrophy, downregulation of cytotoxic T or B lymphocyte differentiation or activation, whereas human immunotoxicities have not been investigated well. This study was undertaken to evaluate overall immunologic spectrum of the Vietnam War Korean veterans exposed to Agent Orange contaminated with TCDD. Quantity of red blood cells, hemoglobin and hematocrit in the veterans suffered from chronic diseases associated with Agent Orange exposure (Veterans-patient group) were decreased in comparison with those of the veterans without the diseases and the age-matched healthy controls, but no differences in leukocyte populations. Plasma IgG levels were lowered in the veterans than the controls, owing to significant decrease in the IgG1 levels. Increase in the IgE levels was observed in the plasma from the veterans. Alteration of T cell-mediated immunity was also resulted from activation of peripheral blood mononuclear cells with polyclonal T cell activators. Production of IFNgamma, a major cytokine mediating host resistance against infection or tumoregenesis, was lowered in the veterans-patient group. However, production of IL-4 and IL-10, representative cytokines involved with hypersensitivity induction, was enhanced in the patient group. Overall, this study suggests that military service in Vietnam and/or Agent Orange exposure disturbs immune-homeostasis resulting in dysregulation of B and T cell activities.

    Radiation is in the public eye because of Fukushima, computed tomography examinations, airport screenings, and possible terrorist attacks. What if the Boston Marathon pressure cooker had also contained a radioactive source? Nuclear power may be on the resurgence. Because of the increasing uses of radiation, the increases in population exposures, and the increasing knowledge of radiation effects, constant vigilance is needed to keep up with the changing times. Psychosocial disorders associated with the inappropriate (but real) fear of radiation need to be recognized as radiation detriments. Radiation risk communication, radiation education, and communication must improve at all levels: to members of the public, to the media, to other scientists, and to radiation professionals. Stakeholders must continue to be involved in all radiation protection initiatives. Finally, we are at a crisis as the number of war babies (me) and baby boomers (you?) who are also radiation professionals continues its rapid decline, and there are few in the pipeline to fill the current and looming substantial need: "The old road is rapidly agin'" (Dylan). NCRP has begun the WARP initiative-Where Are the Radiation Professionals?-an attempt to rejuvenate the pipeline of future professionals before the trickle becomes tiny drops. A Workshop was held in July 2013 with government agencies, military, private sector, universities, White House representatives, and societies to develop a coordinated and national action plan. A "Manhattan Project" is needed to get us "Back to the Future" in terms of the funding levels that existed in years past that provided the necessary resources to train, engage, and retain (a.k.a., jobs) the radiation professionals needed for the nation.

    Due to negligence, Persian (Iranian) traditional medicine has had a weak presence in the world of research for a long time. However, in recent years, a variety of activates by research and faculty centers have created awareness and a platform to introduce and promote Persian medicine to the world. The aim of this study is to present and analyze scientific achievements of Persian medicine in the world of research. Articles were collected from PubMed database using keywords such as "Persian medicine", "Persian traditional medicine", "Iranian medicine", and "Iranian traditional medicine". All data were classified based on the type of research (review, intervention, case reports, etc.), the field of study (neurology, cardiovascular, metabolic, historical studies, etc.), publication year, and journal type. A total of 501 articles were identified until the end of 2015, comprising of 222 reviews and 219 interventional (108 animal, 57 clinical and 54 cellular). Most studies were on neurology (20.1%), gastroenterology (14.5%), and cardiovascular diseases (10.4%). The publications in 2015 and 2014 had the highest hit rate with 139 and 132 articles, respectively, with 1:2 publication ratio between foreign and Iranian journals. The most published articles, both foreign and Iranian, were in "Evidence-Based Complementary and Alternative Medicine" and "Iranian Red Crescent Medicine" journals. The contribution of foreign authors was 5%. The primary focus of the articles was on "Basic concepts of Persian medicine", "Healthy lifestyle according to Persian medicine", and "Historical aspects", by 3.1%, 2.9%, and 6.7%, respectively. During the last 2 years, the number of articles published in Persian (Iranian) medicine, particularly clinical studies had significant growth in comparison with the years before. The tendency of foreign researchers to use the keywords "Iranian" or "Persian" medicine is notable. This research was only based on the designated keyword and other keywords were

    Quantitative and qualitative characteristics of lymphocytes in peripheral blood, thymus and spleen of rats chronically exposed to combined external γ-radiation trichlorfon pesticide effect have been studied. It is shown that chronical combined trichlorfon and γ irradiation effect is accompanied by suppression of lymphopoiesis already at the early stages of the experience. The observed effects are formed depending on both daily and cumulative doses of the effect. The development of the combined effect is based on the summation of effects of chronical effect of ionizing radiation and pesticide. The revealed changes in lymphocytes population exposed to radiation and chemical factors can lead to substantial decrease of natural immunity thereby decreasing to various diseases

    Full Text Available It was claimed by variationists that languages experience variation at all levels, which is supposed to be patterned. The present study aimed at exploring how variation occurred in English and Persian wh-questions. More specifically, it investigated whether such a variation was systematic and patterned. To this end, a modified version of the Edinburgh Map Task was used in data collection. The population of this study was 60 Canadian and Persian native speakers who performed the task through the construction of wh-question variants. The results indicated that both languages experienced variation in the construction of wh-questions. However, Persian proved to be more variable than English because it allowed more wh-question variants to be produced. Moreover, this variation was patterned in English and Persian individually, yet a systematic variation could not be observed between these two languages. It followed that the different mind-sets of the Canadian and Iranian participants which were affected by social and cultural factors might account for such a variation.

    The near-Earth space radiation environment includes energetic galactic cosmic rays (GCR), high intensity proton and electron belts, and the potential for solar particle events (SPE). These sources may penetrate shielding materials and deposit significant energy in sensitive electronic devices on board spacecraft and satellites. Material and design optimization methods may be used to reduce the exposure and extend the operational lifetime of individual components and systems. Since laboratory experiments are expensive and may not cover the range of particles and energies relevant for space applications, such optimization may be done computationally with efficient algorithms that include the various constraints placed on the component, system, or mission. In the present work, the web-based tool OLTARIS (On-Line Tool for the Assessment of Radiation in Space) is presented, and the applicability of the tool for rapidly analyzing exposure levels within either complicated shielding geometries or user-defined material slabs exposed to space radiation is demonstrated. An example approach for material optimization is also presented. Slabs of various advanced multifunctional materials are defined and exposed to several space radiation environments. The materials and thicknesses defining each layer in the slab are then systematically adjusted to arrive at an optimal slab configuration.

    To examine self-rated health (SRH) and its association with social participation, along with physical and mental health indicators, among USA male veterans and non-veterans aged ≥65 years. The two waves of the National Health and Aging Trend Study provided data (n = 2845 at wave 1; n = 2235 at wave 2). Multilevel mixed effects generalized linear models were fit to test the hypotheses. Despite their older age, veterans did not differ from non-veterans in their physical, mental and cognitive health, and they had better SRH. However, black and Hispanic veterans had lower SRH than non-Hispanic white veterans. Formal group activities and outings for enjoyment were positively associated with better SRH for veterans, non-veterans and all veteran cohorts. Aging veterans, especially black and Hispanic veterans, require programs and services that will help increase their social connectedness.

    Full Text Available Due to strategic situation of the Persian Gulf, identifying the petroleum pollution level and source is an important issue. Therefore, this paper enhanced fingerprinting method of applying biomarkers Polycyclic Aromatic Hydrocarbons (PAHs in identifying source and distribution of oil spills of the exposed areas. 10 soil samples collected from the northern coasts of the Persian Gulf along three provinces in the south of Iran. PAH concentrations in the soil ranged from 42.76 to 5596.49 ng.g-1. In the present study the distribution of 3 ringed PAHs was much higher than the other PAHs. Phenanthrene and alkylated derivatives of phenanthrene such as 3-methyl, 2-methyl, 9-methyl and 1-methyl phenanthrene were distinctively higher than the other components. According to the result PAHs concentration can be considered as no or little risk of toxicity for the organisms living in soil except for Fluoranthhene, comparing LD50. Applying marker ratios revealed that in most of the sampling sites showed perogenic sources and it emphasizes on the direct impact of oil and petroleum products to the lands due to oil well exploitation and transferring pipelines.

    Thermoluminescent dosemeters (TLD), widely experimented and utilized in personal dosimetry, have some advantageous characteristics which induce one to employ them also in radiotherapy. The new radiotherapy techniques are aimed at selectively depositing a high dose in cancerous tissues. This goal is reached by utilising both conventional and other more recently proposed radiation, such as thermal neutrons and heavy charged particles. In these inhomogeneous radiation fields a reliable mapping of the spatial distribution of absorbed dose is desirable, and the utilized dosemeters have to give such a possibility without notably perturbing the radiation field with the materials of the dosemeters themselves. TLDs, for their small dimension and their tissue equivalence for most radiation, give good support in the mapping of radiation fields. After exposure to the high fluxes of therapeutic beams, some commercial TL dosemeters have shown a loss of reliability. An investigation has therefore be performed, both on commercial and on laboratory made phosphors, in order to investigate their behaviour in such radiation fields. In particular the thermal neutron and gamma ray mixed field of the thermal column of a nuclear reactor, of interest for Boron Neutron Capture Therapy (B.N.C.T.) and a proton beam, of interest for proton therapy, were considered. Here some results obtained with new TL phosphors exposed in such radiation fields are presented, after a short description of some radiation damage effect on commercial LiF TLDs exposed in the (n th ,γ) field of the thermal column of a reactor.

    Comparative analysis of the findings of clinical and ultrasound study of the thyroid gland in 403 participants of the accident clean-up irradiated in the 'iodine' period and 57 patients with hypothyroidism (of them, 46 were exposed to radiation in the 'iodine' period and 11 in 'non-iodine' one) was carried out. The disease dynamics was investigated in 81 patients with acute radiation sickness. The structural changes suggest different ways of hypothyroidism development in the exposed persons and manifest themselves in two main clinical forms of the disease, atrophic and hypertrophic ones

    There are many indications for excretory urography in humans and animals. Intravenous urography (IVU) is the most practical method about other urography techniques are used because of difficulties for finding veins in IVU, due to small size of the patients. This study was performed to evaluate the feasibility of subcutaneous injection of iodixanol in providing a safe and diagnostic urogram in Persian squirrel. Twelve clinically healthy adult Persian squirrels were prepared and kept for two weeks prior to study. Blood tests were performed 7 days prior to the study. After eighteen hour fasting, animals were sedated by using xylazine/diazepam cocktail (xylazine 5mg/kg, diazepam 30mg/kg). Lateral and ventrodorsal control radiographs were taken. Thirteen hundred and 1800 mg iodine per kilogram body weight of iodixanol was injected subcutaneously over shoulder area in Persian squirrels (each dose for six Persian squirrels). Lateral and ventrodorsal radiographs were taken every 5 m

    Operation CROSSROADS, conducted at Bikini Atoll in 1946, was the first post World War II test of nuclear weapons. Mortality experience of 40,000 military veteran participants in CROSSROADS was compared to that of a similar cohort of nonparticipating veterans. All-cause mortality of the participants was slightly increased over nonparticipants by 5% (p < .001). Smaller increases in participant mortality for all malignancies (1.4%, p = 0.26) or leukemia (2.0%, p = 0.9) were not statistically significant. These results do not support a hypothesis that radiation had increased participant cancer mortality over that of nonparticipants. 8 refs

    Full Text Available Background: Pre-clinical studies for isolation and purification of marine compounds continued at an active pace since the last decade. Today, more than 60% of the anticancer drugs commercially available are of naturally origin thus the sea is a very favorable bed for the discovery of novel anticancer agents. Methods: A total of known 611 seashells species in the Persian Gulf were investigated for synonymy in OBIS database. Then, all the species, including their synonymy were searched in PubMed databse to find their isolated bioactive agents. Results: From 611 known seashells in the Persian Gulf, 172 genera/species had bioactive compounds. Anticancer agents were isolated and purified for 8 genera. These compounds had various structures they were polypeptide, polysaccharide, glycoprotein, alkaloid, cerebroside, and cembranoid which had different mechanism of actions including induction of apoptosis, destroying the skeletal structures of the cells, immune bioactivity and inhibition of topoisomerase I. Spisulosine is the only anticancer agent which is currently under clinical trial. Conclusions: Although, the known seashells from the Persian Gulf have potential anticancer and cytotoxic compounds but a very few investigations had been reported. Further investigations for isolation and purification on bioactive compounds from seashells of the Persian Gulf is recommended.

    The Internet has provided great opportunities for disseminating both accurate and inaccurate health information. Therefore, the quality of information is considered as a widespread concern affecting the human life. Despite the increasingly substantial growth in the number of users, Persian health websites and the proportion of internet-using patients, little is known about the quality of Persian medical and health websites. The current study aimed to first assess the quality, popularity and importance of websites providing Persian health-related information, and second to evaluate the correlation of the popularity and importance ranking with quality score on the Internet. The sample websites were identified by entering the health-related keywords into four most popular search engines of Iranian users based on the Alexa ranking at the time of study. Each selected website was assessed using three qualified tools including the Bomba and Land Index, Google PageRank and the Alexa ranking. The evaluated sites characteristics (ownership structure, database, scope and objective) really did not have an effect on the Alexa traffic global rank, Alexa traffic rank in Iran, Google PageRank and Bomba total score. Most websites (78.9 percent, n = 56) were in the moderate category (8 ≤ x ≤ 11.99) based on their quality levels. There was no statistically significant association between Google PageRank with Bomba index variables and Alexa traffic global rank (P > 0.05). The Persian health websites had better Bomba quality scores in availability and usability guidelines as compared to other guidelines. The Google PageRank did not properly reflect the real quality of evaluated websites and Internet users seeking online health information should not merely rely on it for any kind of prejudgment regarding Persian health websites. However, they can use Iran Alexa rank as a primary filtering tool of these websites. Therefore, designing search engines dedicated to explore accredited

    Using the Minnesota Multiphasic Personality Inventory and the Millon Clinical Multiaxial Inventory, we assessed the psychological functioning of U.S. Air Force veterans exposed to Agent Orange and its contaminant, 2,3,7,8-tetrachlodibenzo-p-dioxin (dioxin), during the Vietnam War. Index subjects were veterans of Operation Ranch Hand (N = 1,109). Comparisons (N = 1,493) were U.S. Air Force veterans not involved with spraying herbicides. We found few consistent psychological abnormalities associated with serum dioxin levels. Ranch Hand veterans with higher dioxin levels showed some difficulties in anxiety, somatization, depression, and a denial of psychological factors. However, those with background levels also showed indications of emotional distress, primarily in emotional numbing and lability; a guarded, suspicious, and withdrawn style of relating to others; and unusual thoughts or behaviors.

  16. The modes of death in mammals exposed to whole body radiation (acute radiation syndromes)

    When an animal is exposed to a sufficient amount of radiation, there will be changes in many organs of the body, and as a result of either the effects in one particular organ or the interaction of effects in several organs, the animal as a whole will show characteristic syndromes. Some syndromes result inevitably in death. Others may or may not be lethal, depending on the extent of the tissue damage. The time of appearance of the syndromes, their duration, and the survival of the organism depend on many factors. Whole body acute doses of radiation produce the same spectrum of Central Nervous System (CNS), Gastrointestinal (GI) and Bone Marrow (BM) injury in man as was described for animals. Damage to the skin, ovary and testis are an integral and important part of the symptoms. (author) [pt

    The Multiple Sclerosis Walking Scale-12 (MSWS-12) is a multi-item rating scale used to assess the perspectives of patients about the impact of MS on their walking ability. The aim of this study was to examine the reliability and validity of the MSWS-12 in Persian speaking patients with MS. The MSWS-12 questionnaire was translated into Persian language according to internationally adopted standards involving forward-backward translation, reviewed by an expert committee and tested on the pre-final version. In this cross-sectional study, 100 participants (50 patients with MS and 50 healthy subjects) were included. The MSWS-12 was administered twice 7 days apart to 30 patients with MS for test and retest reliability. Internal consistency reliability was Cronbach's α 0.96 for test and 0.97 for retest. There were no significant floor or ceiling effects. Test-retest reliability was excellent (intraclass correlation coefficient [ICC] agreement of 0.98, 95% CI, 0.95-0.99) confirming the reproducibility of the Persian MSWS-12. Construct validity using known group methods was demonstrated through a significant difference in the Persian MSWS-12 total score between the patients with MS and healthy subjects. Factor analysis extracted 2 latent factors (79.24% of the total variance). A second factor analysis suggested the 9-item Persian MSWS as a unidimensional scale for patients with MS. The Persian MSWS-12 was found to be valid and reliable for assessing walking ability in Persian speaking patients with MS. Copyright © 2014 Elsevier B.V. All rights reserved.

    Pruritus is an unpleasant feeling that can cause the desire of scratching in a person and can be the symptoms of systemic, infectious, and neurological diseases. Pruritus is the most common clinical manifestation of skin diseases. Pruritus prevalence is 8-38% in the general population. Causes and treatments of pruritus have been described by traditional Persian medicine scientists. The aim of this study was to derive general principles of the proposed treatment to reduce or relieve pruritus. This descriptive study, review traditional medicine books including Al canon fil tibb, Al-Hawi, Makhzan ul-adviyyah, Al-Abniyah an-Haghyegh el-adviyah, Tuhfat ul-Momineen and Exir-e-Azam. The above-mentioned documents were derived and classified by keywords such as pruritus, hakka, jarab and sherry. In traditional Persian medicine, there are different causes for pruritus such as accumulation of vapors or acute humors in subcutaneous tissue or weakness of expulsive (Dafi'a) faculty and its treatment is based on removing the causes. Proper nutrition, bathing, and removing pathogenic humors are involved in the treatment. According to this study, some plants such as Cassia fistula, Purslane, Violets, Fumaria, Barley, Coriander, Rose and Terminalia chebula are anti-itching. Proper nutrition is the most important point in health and treatment of humors production with appropriate quality and quantity. Pruritus can be treated by lifestyle modification and using medicinal plants. It could be concluded that traditional Persian medicine therapies can be effective in the treatment of pruritus with mild side effects. By further investigation and research, we can reach more effective treatment methods in the field of traditional Persian medicine along with other new medical therapies.

    Environmental mutagens such as ionizing radiation and chemicals induce DNA damage in a wide variety of organisms. The International Commission on Radiological Protection (lCRP) has recently emphasized the need to protect non-human biota from the potential effects of ionizing radiation. Radiation exposures to non-humans can occur as a result of low-level radioactive discharges into the environment. Molecular genetic effects at low-level radiation exposures are largely unexplored and systematic studies using sensitive biomarkers are required to assess DNA damage in representative non-human species. The objective of the study was to detect DNA damage in the fish Catla catla exposed to gamma radiation using flow cytometry at different time intervals. Increases in the coefficient of variation (CV) of the G 0 /G 1 peak, indicating abnormal DNA distributions were observed in fish exposed to gamma radiation than in controls. Significant increase in the CV was observed from day 12-90 and thereafter decreased. This increase in CV might be due to DNA damage in the cell populations at G 0 /G 1 phase or deletions and duplications caused by improper repair of chromosomes in the cell-cycle machinery. Ionizing radiation induced cell-cycle perturbations and apoptosis were also observed after gamma radiation exposure. (author)

    The radiative properties of polymers exposed to high-intensity radiation are of importance for the numerical simulation of arc-induced ablation. The paper investigates the optical properties of polymethylmethacrylate PMMA and polyamide PA6 films exposed to high-power arc plasmas, which can cause ablation of the material. A four-flux radiative approximation is first used to estimate absorption and scattering coefficients of the tested materials in the ultraviolet (UV) and in the visible (VIS) ranges from spectrophotometric measurements. The temperature-induced variation of the collimated transmissivity of the polymers is also measured from room temperature to the glass temperature of PMMA and the melting temperature of PA6. Furthermore, band-averaged absorption and scattering coefficients of non-ablating and ablating polymers are estimated from the UV to the short-wavelength infrared (SWIR), covering the range of interest for the simulation of arc-induced ablation. These estimates are obtained from collimated transmissivities measured with an additional in situ photometric system that uses a high-power, transient arc plasma to both illuminate the samples and to induce ablation. It is shown that the increase in the bulk temperature of PA6 leads to a strong reversible increase in collimated transmissivity, significantly reducing the absorption and scattering coefficients of the material. A weaker but opposite effect of temperature on the optical properties is found in PMMA. As a consequence, it is suggested that the absorption coefficient of polymers used for arc-induced ablation estimates should not be taken directly from direct collimated transmissivity measurements at room temperature. The band-averaged radiation measurements also show that the layer of products released by ablation of PMMA produces scattering radiation losses mainly in the VIS-SWIR ranges, which are only a small fraction of the total incident arc radiation. In a similar manner, the ablation layer

    Solar ultraviolet radiation (UVR) exposure is widely recognised as a leading cause of skin cancer, with outdoor workers being particularly at risk. Little is known on a national level about how many workers are exposed to solar radiation, the circumstances in which they are exposed, or their use of protective measures. The Australian Work Exposures Study (AWES) was a cross-sectional telephone survey of 5,023 Australian workers aged 18 to 65. A subset of 1,113 respondents who indicated they worked outdoors was asked about their exposure to solar radiation in terms of the amount of time they spent working outdoors, their working location and their use of sun protective measures. A total of 1,100 respondents (22% overall) were assessed as being exposed to solar radiation at work. Exposure was more likely among males and those residing in lower socioeconomic and regional areas. Sun protection was used by 95% of the respondents, although the level of protection varied among workers, with only 8.7% classified as fully protected. This study provides valuable information regarding solar exposure that has not previously been available. The results of this study will inform strategies for risk reduction. © 2014 The Authors.

    The aim of the present study was to assess occupationally induced chromosomal damage in hospital workers exposed to low levels of ionizing radiation. Thirty-two interventional cardiologists, 36 nuclear medicine physicians and 33 conventional radiologists were included in this study, along with 35 healthy age- and sex-matched individuals as the control group. We used conventional metaphase chromosome aberration (CA) analysis, cytokinesis-block micronucleus (MN) assay as important biological indicators of ionizing radiation exposure. Occupational dosimetry records were collected over the last year (ranged from 0.25 to 48 mSv) and their whole life exposure (ranged from 1.5 to 147 mSv). The results showed significantly higher frequencies of dicentric and acentric CAs (p < 0.001) and MN (p < 0.01) in all exposed groups than in the controls. Taking all the confounding factors into account, no obvious trend of increased chromosomal damages as a function of either duration of employment, exposed dose, sex or age was observed. Interventional cardiologists had the highest rates of CA and MN frequencies between the worker groups, though the differences were not significant. These results indicate that long term exposure to low dose ionizing radiation could result in DNA damage. Hence, the personnel who work in the hospitals should carefully apply the radiation protection procedures.

    2015-11-01

    Full Text Available Dubbing is one of the developing areas in Translation Studies, and this study aimed at investigating the translation strategies used in the dubbing of comedy animations from English to Persian. Since colloquial, idiomatic, and humorous expressions have the capacity to elicit laughter and as it is not always easy to draw a clear-cut line between these three types of expressions, this study examines all three types, investigating the strategies used in translating these expressions. The data was collected from five popular American comedy animations dubbed into Persian. The original humorous, colloquial, and idiomatic expressions and their Persian translations were written down and the strategies used in translating them were identified and classified into nine groups for further analysis. The findings from the sample demonstrate that the Persian translators tend to use familiar expressions rather than translate literally and that beside humorous expressions, the translators tend to use idiomatic and colloquial expressions to produce laughter mostly in cases where the original animation has not used them. In short, the Persian translators have frequently and freely used idiomatic and colloquial expressions in their secondary function to elicit laughter which is a strategy that can be used in the translation of comedies, especially for children, where there are numerous linguistic and cultural barriers across the cultures.

    The sociocultural identities that people self-assign or accept influence their interpersonal interactions and decision making. Identity-based interventions attempt to influence individuals by associating healthy behaviors with in-group membership. Outreach and educational efforts aimed at veterans may rely on "typical" veteran identity stereotypes. However, as discussed in this Open Forum, there is evidence that veteran identity is not monolithic but rather fluctuates on the basis of personal characteristics and individual military service experiences. Overall, the impact of veteran identity on veterans' health behaviors and use of health care is not known and has been understudied. A major limiting factor is the lack of a standardized measure of veteran identity that can assess variations in salience, prominence, and emotional valence.

    Full Text Available Today, the mobile phone, with its wide range of features, is an inexpensive, easy to use, and most modern communication tool. One of the special applications of smart phones is providing spaces and facilities such as SMS services, virtual networks, and interactive groups that link people and groups from different linguistic and cultural background. In this paper, we tried to study the messages of the Farsi-speaking users of the Telegram communication network from the linguistics perspective. In this regard, the linguistics and rhetorical correspondence of short messages in Persian language was studied by the content-analysis method. The statistical population consisted of 150 messages which contained 327 sentences. These messages were randomly selected from 5 different groups. Persian language used in cyberspace differs from standard Persian language. The first step in correcting communication language errors in cyberspace is to inform the users about the type of errors.

    Chromosome aberrations frequency was estimated in peripheral lymphocytes from hospital workers occupationally exposed to low levels of ionizing radiation and controls. Chromosome aberrations yield was analyzed by considering the effects of dose equivalent of ionizing radiation over time, and of confounding factors, such as age, gender and smoking status. Frequencies of aberrant cells and chromosome breaks were higher in exposed workers than in controls (P=0.007, and P=0.001, respectively). Seven dicentric aberrations were detected in the exposed group and only three in controls, but the mean frequencies were not significantly different. The dose equivalent to whole body of ionizing radiation (Hwb) did appear to influence the spectrum of chromosomal aberrations when the exposed workers were subdivided by a cut off at 50 mSv. The frequencies of chromosome breaks in both subgroups of workers were significantly higher than in controls (≤50 mSv, P=0.041; >50 mSv, P=0.018). On the other hand, the frequency of chromatid breaks observed in workers with Hwb >50 mSv was significantly higher than in controls (P=0.015) or workers with Hwb ≤50 mSv (P=0.046). Regarding the influence of confounding factors on genetic damage, smoking status and female gender seem to influence the increase in chromosome aberration frequencies in the study population. Overall, these results suggested that chromosome breaks might provide a good marker for assessing genetic damage in populations exposed to low levels of ionizing radiation

    Sexual dysfunction has been demonstrated to be related to a poor quality of life. These dysfunctions are especially prevalent among men. This cross-sectional study aimed to investigate the psychometric properties of the Persian translation of the Sexual Quality of Life–Male (SQOL-M), translated and adapted to measure sexual quality of life among Iranian men. Forward–backward procedures were applied in translating the original SQOL-M into Persian, and then the psychometric properties of the Persian translation of the SQOL-M were studied. A total of 181 participants (23-60 years old) were included in the study. Validity was assessed by construct validity using confirmatory factor analysis, convergent validity, and content validity. The international index of erectile function (IIEF) and the work ability index were used to study the convergent validity. Reliability was evaluated through internal consistency and test–retest reliability analyses. The results from confirmatory factor analysis confirmed a one-factor solution for the Persian version of the SQOL-M. Content validity of the translated measure was endorsed by 10 specialists. Pearson correlations indicated that work ability index score, dimensions of the IIEF, and the IIEF total score were positively correlated with the Persian version of the SQOL-M (p Persian version of the SQOL-M has good to excellent psychometric properties and can be used to assess the sexual quality of life among Iranian men.

    It has been shown that smoking may be affected by metacognitions. This study aimed to evaluate the factor structure, reliability and validity of the Persian version of the Metacognitions about Smoking Questionnaire (MSQ) among a sample of Iranian male smokers. When the English to Persian translation of the MSQ was performed, exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were completed according to the four-factor solution of the original MSQ. Three hundred male treatment-seeking smokers (mean age = 41.37, SD = 15.90) filled out the Persian-translated version of the MSQ, the Smoking Effects Questionnaire (SEQ), and the Nicotine Dependence Syndrome Scale (NDSS). The results of EFA revealed that the Persian version of the MSQ had a four-factor structure named positive metacognitions about cognitive regulation (PM-CR), positive metacognitions about emotional regulation (PM-ER), negative metacognitions about uncontrollability (NM-U), and negative metacognitions about cognitive interference (NM-CI). The findings of CFA also indicated that the four-factor structure of the Persian version of the MSQ had appropriate fit. Validity and reliability of the Persian version of the MSQ were found to be good. Negative metacognitions about smoking predicted nicotine dependence over and above smoking outcome expectancies.

    We investigated the association between exposure to chemical warfare and chronic mental/physical conditions. This was a secondary analysis of data from a case-control study on Iranian male veterans. Participants with neuropsychiatric disorders other than depressive/anxiety disorders, anatomical defects, or malignancies were excluded. Compared to non-exposed veterans, exposed veterans demonstrated significantly higher odds of PTSD [OR (95% CI) = 5.23 (1.98-13.85)], hypertension [OR (95% CI) = 5.57 (1.68-18.48)], coronary heart disease [OR (95% CI) = 6.8 (1.62-28.49)], and diabetes [OR (95% CI) = 3.88 (1.35-11.16)], and marginally higher odds of moderate to severe depressive symptoms [OR (95% CI) = 2.21 (0.93-5.28)]. This study provides preliminary evidence on association of exposure to chemical warfare with long-term mental disorders as well as chronic medical conditions.

In Washington the rhetoric from both the political right and left supports our Veterans. My cynical side reminds me that this might have something to do with Veterans voting in a higher percentage than the population as a whole, but let me give the politicians this one. Serving our Country in the military is something that deserves to be honored. I was proud to serve our Veterans over 30 years at the four Department of Veterans Affairs (VA hospitals. However, the VA has had a very bad year. First, in Washington there were the resignations of the Secretary of Veterans Affairs, Eric Shinseki; the undersecretary for the Veterans Health Administration, Robert Petzel; and the undersecretary for the Veterans Benefits Administration, Allison Hickey. Locally, in the light of the VA wait scandal there were the firing of ...

    Cat breeders observed a frequent occurrence of internal hydrocephalus in Persian cats with extreme brachycephalic head morphology. To investigate a possible relationship among the grade of brachycephaly, ventricular dilatation, and skull dysmorphologies in Persian cats. 92 Persian-, 10 Domestic shorthair cats. The grade of brachycephaly was determined on skull models based on CT datasets. Cranial measurements were examined with regard to a possible correlation with relative ventricular volume, and cranial capacity. Persians with high (peke-face Persians) and lower grades of brachycephaly (doll-face Persians) were investigated for the presence of skull dysmorphologies. The mean cranial index of the peke-face Persians (0.97 ± 0.14) was significantly higher than the mean cranial index of doll-face Persians (0.66 ± 0.04; P < 0.001). Peke-face Persians had a lower relative nasal bone length (0.15 ± 0.04) compared to doll-face (0.29 ± 0.08; P < 0.001). The endocranial volume was significantly lower in doll-face than peke-face Persians (89.6 ± 1.27% versus 91.76 ± 2.07%; P < 0.001). The cranial index was significantly correlated with this variable (Spearman's r: 0.7; P < 0.0001). Mean ventricle: Brain ratio of the peke-face group (0.159 ± 0.14) was significantly higher compared to doll-face Persians (0.015 ± 0.01; P < 0.001). High grades of brachycephaly are also associated with malformations of the calvarial and facial bones as well as dental malformations. As these dysmorphologies can affect animal welfare, the selection for extreme forms of brachycephaly in Persian cats should be reconsidered. Copyright © 2017 The Authors.

    Tinnitus is a common otologic symptom that can seriously affect a patient's quality of life. The purpose of the present study was to translate and validate the Iowa Tinnitus Handicap Questionnaire (THQ) into the Persian language, and to make it applicable as a tool for determining the effects of tinnitus on a patient's life. The main version of the THQ was translated into the Persian language. The agreed Persian version was administered to 150 tinnitus patients. The validity of the Persian THQ was evaluated and internal reliability was confirmed using Cronbach's α-coefficient. Finally, the effect of independent variables such as age, mean patient threshold, gender, and duration of tinnitus were considered in order to determine the psychometric properties of tinnitus. After an exact translation process, the Persian THQ was found to exhibit face validity. In terms of content validity, content validity index in total questionnaire was 0.93. Further, in structural validity measurements, intermediate correlation with annoyance from tinnitus (r=0.49), low correlation with duration of tinnitus (r=0.34) and high correlation with the Tinnitus Handicap Inventory (THI) questionnaire (r=0.84) were demonstrated. Additionally, a negligible effect of gender and age was noted on degree of tinnitus handicap (P= 0.754, P= 0.573, respectively). In the internal reliability assessment for Factors 1, 2, 3, and the whole questionnaire, Cronbach`s α-coefficient was 0.95, 0.92, 0.25 and 0.88, respectively. The Persian version of the Iowa THQ demonstrates high validity and reliability and can be used for the determination of tinnitus handicap and for following-up in the intervention process in Persian tinnitus patients.

    From July 1965 until November 1971, New Zealand Defence Force Personnel fought in the Vietnam War. During this time more than 76,500,000 litres of phenoxylic herbicides were sprayed over parts of Southern Vietnam and Laos, the most common being known as 'Agent Orange'. The current study aimed to ascertain whether or not New Zealand Vietnam War veterans show evidence of genetic disturbance arising as a consequence of their now confirmed exposure to these defoliants. A sample group of 24 New Zealand Vietnam War veterans and 23 control volunteers were compared using an SCE (sister chromatid exchange) analysis. The results from the SCE study show a highly significant difference (P Vietnam War veterans studied here were exposed to a clastogenic substance(s) which continues to exert an observable genetic effect today, and suggest that this is attributable to their service in Vietnam.

    To research the effect of 27.2 MHz radiofrequency radiation on electrocardiograms (ECG), 225 female workers operating radiofrequency machines at a shoe factory were chosen as the exposure group and 100 female workers without exposure from the same factory were selected as the control group. The 6 min electric field strength that the female workers were exposed to was 64.0 ± 25.2 V/m (mean ± SD), which exceeded 61 V/m, the International Commission on Non-Ionizing Radiation Protection reference root mean square levels for occupational exposure. A statistical difference was observed between the exposed group and the control group in terms of the rate of sinus bradycardia (χ(2)  = 11.48, P = 0.003). When several known risk factors for cardiovascular disease were considered, including smoking, age, alcohol ingestion habit, and so on, the exposure duration was not an effective factor for ECG changes, sinus arrhythmia, or sinus bradycardia according to α = 0.05, while P = 0.052 for sinus arrhythmia was very close to 0.05. We did not find any statistical difference in heart rate, duration of the QRS wave (ventricular depolarization), or corrected QT intervals (between the start of the Q wave and end of the T wave) between the exposed and control groups. Occupational exposure to radiofrequency radiation was not found to be a cause of ECG changes after consideration of the confounding factors. Copyright © 2012 Wiley Periodicals, Inc.

    We aimed to validate a cross-culturally adapted version of the Persian Michigan Hand Outcomes Questionnaire (MHOQ). We followed the Beaton's guideline to translate the questionnaire to Persian. We administered the final version to 223 patients among which 79 patients returned 3 days later to respond to the Persian MHOQ for the second time. In the first visit, respondents also filled the Disabilities of the Arm Shoulder and Hand (DASH) and rated the pain based on the Visual Analogue Scale (VAS). Cronbach's alpha for the total MHOQ was 0.79 which showed good internal consistency. Intraclass correlation coefficient (ICC) for the total MHOQ was 0.84 which demonstrated good reliability between test and retest. The absolute correlation coefficient between total MHOQ and the DASH was as high as 0.74. Persian version of the MHOQ proved to be a reliable and valid instrument to be implemented among Persian population with the hand and wrist disorders.

    Numerical simulation of oil slick movement with respect to tidal factors and wind effects was performed in order to counteract oil pollution in the Persian Gulf. First, a flow model was invoked with respect to water level fluctuations. The main tidal constituents were applied to the model using the initial conditions of water level variations in the Hormuz Strait near the Hangam Island. The movement of oil pollution was determined due to wind, tide and temperature effects and confirmed by applying a verified field results. Simulations were focused near an important terminal in the Persian Gulf, Assaluyeh Port. The results were led to preparing a risk-taking map in a parallel research for the Persian Gulf.

    Silver nanoparticles (AgNPs) are widely used in consumer products mainly due to their antimicrobial action. The rapidly increasing use of nanoparticles (NPs) has driven more attention to their possible ecotoxicological effects. In this study, the acute toxicity of colloidal AgNPs was evaluated during the embryonic stage of Persian sturgeon (Acipenser persicus) and starry sturgeon (Acipenser stellatus) at concentrations of 0, 0.25, 0.5, 1, 2, 4, and 8 mg/L. Fertilized eggs (75 eggs per replicate) were exposed to aforementioned concentrations for 96 h in triplicate. 96-h LC50 values in Persian sturgeon and starry sturgeon were calculated as 0.163 and 0.158 mg/L, respectively. Furthermore, in starry sturgeon, the short-term effects of AgNPs on the hatching rate, survival rate, and Ag accumulation during early life stages (before active feeding commences) were also analyzed at concentrations of 0, 0.025, 0.05, and 0.1 mg/L of colloidal AgNPs. The highest silver accumulation occurred in larvae exposed to 0.1 mg/L AgNPs; however, the body burden of silver did not alter survival rate, and there were no significant differences among treatments. Based on the obtained results from the acute toxicity exposures, AgNPs induced a concentration-dependent toxicity in both species during early life stages, while complementary studies are suggested for investigating their short-term effects in detail.

    Freshly collected peripheral blood samples from four healthy human volunteers were diluted with RPMI 1640 tissue culture medium and exposed in sterile T-75 tissue culture flasks in vitro for 24 h to 835.62 MHz radiofrequency (RF) radiation, a frequency employed for customer-to-base station transmission of cellular telephone communications. An analog signal was used, and the access technology was frequency division multiple access (FDMA, continuous wave). A nominal net forward power of 68 W was used, and the nominal power density at the center of the exposure flask was 860 W/m(2). The mean specific absorption rate in the exposure flask was 4.4 or 5.0 W/kg. Aliquots of diluted blood that were sham-exposed or exposed in vitro to an acute dose of 1.50 Gy of gamma radiation were used as negative or positive controls. Immediately after the exposures, the lymphocytes were stimulated with a mitogen, phytohemagglutinin, and cultured for 48 or 72 h to determine the extent of genetic damage, as assessed from the frequencies of chromosomal aberrations and micronuclei. The extent of alteration in the kinetics of cell proliferation was determined from the mitotic indices in 48-h cultures and from the incidence of binucleate cells in 72-h cultures. The data indicated no significant differences between RF-radiation- and sham-exposed lymphocytes with respect to mitotic indices, incidence of exchange aberrations, excess fragments, binucleate cells, and micronuclei. In contrast, the response of the lymphocytes exposed to gamma radiation was significantly different from both RF-radiation- and sham-exposed cells for all of these indices. Thus, under the experimental conditions tested, there is no evidence for the induction of chromosomal aberrations and micronuclei in human blood lymphocytes exposed in vitro for 24 h to 835.62 MHz RF radiation at SARs of 4.4 or 5.0 W/kg.

    The aim of the present study was to develop and provide validation statistics for the Persian Injury-Psychological Readiness to Return to Sport scale (I-PRRS) following a cross-sectional and prospective cohort study design. The I-PRRS was forward/back-translated and culturally adapted into Persian language. The Persian I-PRRS was administered to 100 injured athletes (93 male; age 26.0 ± 5.6 years; time since injury 4.84 ± 6.4 months) and 50 healthy athletes (36 male; mean age 25.7 ± 6.0 years). The Persian I-PRRS was re-administered to 50 injured athletes at 1 week to examine test-retest reliability. There were no floor or ceiling effects confirming the content validity of Persian I-PRRS. The internal consistency reliability was good. Excellent test-retest reliability and agreement were demonstrated. The statistically significant difference in Persian I-PRRS total scores between the injured athletes and healthy athletes provides an evidence of discriminative validity. The Persian I-PRRS total scores were positively correlated with the Farsi Mood Scale (FARMS) total scores, showing construct validity. The principal component analysis indicated a two-factor solution consisting of "Confidence to play" and "Confidence in the injured body part and skill level". The Persian I-PRRS showed excellent reliability and validity and can be used to assess injured athletes' psychological readiness to return to sport among Persian-speaking populations.

    Full Text Available   The wind drift motion of the water which is produced by the stress of the wind exerted upon the surface of the ocean is described by Ekmans theory (1905. Using the mean monthly values for the wind stress and SST, seasonal Ekman transport for the Persian Gulf was computed and contoured. The geostrophic winds have combined with the SST to estimate the effect of cooling due to Ekman transport of colder northern waters and inflow from the Oman Sea. The monthly SST mainly obtained from the 10 10 grided data of Levitus atlas and Hormuz Cruis Experiment for 1997.   Analyses show a NW to SE Ekman transport due to wind stress and significant interannual variability of SST on sea surface in the Persian Gulf. The seasonal variation of SST shows a continental pattern due to severe interaction between the land and sea. But these variations somehow moderates because of Ekman transport in Persian Gulf.

    Full Text Available Mohammad Moin has been considered as one of the most committed literary men of the present time who recorded a considerable amount of Persian words, expressions, and declarations in his own 6 volumes Persian dictionary according to scientific research methods and in a different way in comparison to the previous dictionaries. This article argues the quality of colloquial infinitives which have been recorded in Moin Persian Dictionary. The most important obstacles in all researches related to literature and colloquial language is the recognition criterion of "being colloquial". In this article, the recognition criterion is that of Moin's criterion who was a great master in this field. In the other words, any infinitives in front of which he put the abbreviation "Ɂam", have been extracted and at the next stage, according to the syntactic resources, have been divided into 8 categories. Finally, the examples of each category have been presented through tables.

    To assess the cognitive status in persons exposed to ionizing radiation in prenatal period. The study included in-utero exposed people (n = 77), and the comparison group (n = 73), which consisted of people who lived in the territories of the Chelyabinsk Oblast that were not radioactive. The following methods were used: clinical, clinical-psychological (Mini-Mental State Examination (MMSE), the WAIS test, the proverb interpretation task, neurophysiological (EEG) methods, laboratory-based methods (cholesterol, high and low-density lipoproteins, triglycerides, cortisol, melatonin), and methods of statistical data processing. The number of people with non-psychotic mental disorders with the prevalence of organic mental disorders (cognitive and asthenic) was significantly higher among in-utero exposed subjects. A neurophysiological study revealed more severe changes in the bioelectric brain activity with the presence of pathological and theta-rhythms in exposed persons. The clinical-psychological study revealed a significant decrease in the analytic/synthetic ability in exposed people and significantly lower level of the general and verbal IQ. These changes were accompanied by higher levels of cortisol and melatonin which led to the activation and tension of the adaptation mechanisms in in-utero exposed subjects.

    Orthopedic surgeons should be considered as professionals occupationally exposed to ionizing radiation, for using C arc (fluoroscope) an equipment of X type radiation emission, during surgical procedures for imaging generation. Some health institutes, use of C arc under uncontrolled circumstances, such a lack of dosimetry control, incomplete or absence of personnel protective elements and protective measures, which in turn, lead to a high exposition to the personnel. Materials and methods. Study of double match cohort by age and gender, was conducted, in four health institutions of second and third level of attention in Bogota city. Personal dosimetry measurements with TLD-100 dosimetry crystals in both cohorts and environmental dosimetry in each of operation rooms used for orthopedic procedures, were carry out during six months of follow up. Dosimetry crystals were read in a Harshaw 4500 - Bicron equipment, in the Medical Physics Laboratory of National University of Colombia. Results. Dosimetry measurements are compatibles with those of occupationally exposed personnel 3.44 mSv/6 m CI 95% (1.66-3.99), even does not overpass ICRP recommendations, are higher as were expect at the beginning of the study. The median of effective accumulative dose in thorax is 3,4 mSv CI 95% (1,66-3,99), higher in comparison with neck value 2,7 mSv CI 95% (1,73-3,80) and hand dosimetry 1,42 mSv CI 95% (0,96-2,34). Conclusions: Orthopedic surgeons should be considered occupational exposed to ionizing radiation, who has to accomplish to the radiological protection measures, dosimetric follow up and maintenance of the used X ray equipment. It was confirm throughout this study that dosimetry shows higher levels as expected at the beginning of the study, compatible with occupationally exposed personnel. (Author)

    Background: Functional gastrointestinal diseases are common in general populations and comprise more than 40% visits to gastroenterologists. Treatment options of gastrointestinal diseases have been limited. There are a few medications for functional gastrointestinal diseases and some of medications are not available in the market or in the place where the patient lives. Traditional Persian medicine (TPM) is a branch of alternative and traditional medicine based on individual viewpoint and humoral theory, focuses on lifestyle modification and uses natural products to manage the patients. Methods: In this study, a set of compound drugs known as digesters (jawarishes) and other applications are described based on main TPM text books. Results: Jawarishes have different formulations containing various medicinal herbs used for better food digestion and improved gastric functions and also used for other disorders including reinforcing the brain, heart, liver and some therapeutic approaches. Conclusions: By reviewing medieval Persian pharmaceutical manuscripts, we can conclude that many herbs are effective in different systems of the body and improve gastric functions. Zingiber officinalis and Piper nigrum are mixed together to get various formulations. The variety of jawarishes formulations and their different clinical applications can indicate continuity of their use. PMID:29387312

  1. Serving Our Homeless Veterans: Patient Perpetrated Violence as a Barrier to Health Care Access

    2017-07-01

    Full Text Available In 2009, the Department of Veterans Affairs (VA set a goal to end veteran homelessness by 2015. Since then there has been a 36% reduction in homelessness due, in part, to the VA Supportive Housing (HUD-VASH program. These services include the receipt of home-based services to the veterans’ home. However, safety concerns and the threat of violence toward health care workers remain problematic in non-institutional care settings. This article discusses the concept of access to care and how safety concerns act as a barrier to services and optimal patient outcomes. Our study provides information on the prevalence of patient violence toward health care workers in the HUD-VASH program in a large veterans’ health system. Results suggest 70% of home-based service providers were exposed to violence and aggression. Providing services to veterans outside of institutional care settings, and the goal of eradicating homelessness among veterans, warrants further examination of access barriers.

    The objective: evaluation of the peri-ungual capillaroscopy as diagnostic tool and screening of secondary infra clinical lesions to a chronic exposure to X ionizing radiation. Material and methods: the whole of personnel exposed of the Grenoble university hospital center, as well as a non exposed physician population chosen according to age criteria, had benefit of a peri-ungual capillaroscopy. An estimation of the exposure level was realised, allowing the constitution of exposure groups. Seven qualitative capillaroscopic variables were evaluated: dilatation, hemorrhages, edema, capillary rarefaction, tortuosity, capillary density and background color. Results: two homogenous populations in term of age: 32 exposed subjects, for essential cardiologists and interventional radiologists; 35 non exposed subjects. No statistically significant difference was enlightened, in the comparison of exposed- non exposed groups and in the comparison of the most exposed group to the control group. Discussion: the low statistical power of this study does not allow to conclude to the lack of inter group difference. This result disagrees with the literature, but these works are not easily comparable. Conclusion: the importance of the stake and the surveillance of the operators hands justifies the realisation of a multi centric great scope study. (N.C.)

    We performed a study on the presence of chromosome aberrations in a cohort of plutonium workers of the Mayak production association (PA) with a mean age of 73.3 ± 7.2 years to see whether by multi-color fluorescence in situ hybridization (mFISH) translocation analysis can discriminate individuals who underwent occupational exposure with internal and/or external exposure to ionizing radiation 40 years ago. All Mayak PA workers were occupationally exposed to chronic internal alpha-radiation due to incorporated plutonium-239 and/or to external gamma-rays. First, we obtained the translocation yield in control individuals by mFISH to chromosome spreads of age-matched individuals and obtained background values that are similar to previously published values of an international study (Sigurdson et al. in Mutat Res 652:112-121, 2008). Workers who had absorbed a total dose of >0.5 Gy external gamma-rays to the red bone marrow (RBM) displayed a significantly higher frequency of stable chromosome aberrations relative to a group of workers exposed to <0.5 Gy gamma-rays total absorbed RBM dose. Thus, the translocation frequency may be considered to be a biological marker of external radiation exposure even years after the exposure. In a group of workers who were internally exposed and had incorporated plutonium-239 at a body burden >1.48 kBq, mFISH revealed a considerable number of cells with complex chromosomal rearrangements. Linear associations were observed for translocation yield with the absorbed RBM dose from external gamma-rays as well as for complex chromosomal rearrangements with the plutonium-239 body burden.

    As a result of the 1991 Persian Gulf war, between mid-January and June 1991, the Persian Gulf was contaminated with an estimated 4 to 6 million barrels of crude oil, released directly into the Gulf from refinement facilities, transhipment terminals, and moored tankers along the coast of Kuwait, and precipitated from oil fire smoke plumes. To assess the environmental impact of the oil, an international team of marine scientists representing 14 nations was assembled under the auspices of the United Nations International Oceanic Commission and the Regional Organization for Protection of the Marine Environment to conduct detailed surveys of the Persian Gulf, the Strait of Hormuz, and the Gulf of Oman, including hydrographic, chemical, and biological measurements. To supplement the field surveys and to serve as an aid in data interpretation, astronauts aboard the Space Shuttle Atlantis photographed water features and coastal habitats in the Persian Gulf during mission STS-45 (24 March to 02 April 1992). The astronauts collected 111 hand-held, color photographs of the Gulf (72 70-mm photographs and 39 5-inch photographs) from an altitude of 296 km (160 n.mi.). The photographs reveal distributions in water turbidity associated with outflow from the Shatt-al-Arab and water circulation along the entire coast of Iran and the Strait of Hormuz, coastal wetlands and shallow-water habitats, and sticks appearing in the sunglint pattern, which appear to be oil.

    We examine the frames the elite news media uses to portray veterans on and surrounding Veterans Day 2012, 2013, 2014, and 2015. We use mental health illness and media framing literature to explore how, why, and to what extent Veterans Day news coverage uses different media frames across the four consecutive years. We compiled a Media Coverage Corpora for each year, which contains the quotes and paraphrased remarks used in all veterans news stories for that year. In our primary study, we applied the meaning extraction method (MEM) to extract emergent media frames for Veterans Day 2014 and compiled a word frequency list, which captures the words most commonly used within the corpora. In post hoc analyses, we collected news stories and compiled word frequency lists for Veterans Day 2012, 2013, and 2015. Our findings reveal dissenting frames across 2012, 2013, and 2014 Veterans Day media coverage. Word frequency results suggest the 2012 and 2013 media frames largely celebrate Veterans as heroes, but the 2014 coverage depicts veterans as victimized by their wartime experiences. Furthermore, our results demonstrate how the prevailing 2015 media frames could be a reaction to 2014 frames that portrayed veterans as health victims. We consider the ramifications of this binary portrayal of veterans as either health victims or heroes and discuss the implications of these dueling frames for veterans' access to healthcare resources.

    Military sexual trauma (MST) is prevalent among female Veterans and is associated with increased risk for suicidal self-directed violence. Yet research examining processes which contribute to suicidal ideation and attempts among MST survivors has been sparse, focusing primarily on psychiatric symptoms or diagnoses, rather than employing a theory-driven approach. The interpersonal-psychological theory (Joiner, 2005) is a leading theory of suicide that may be particularly relevant for understanding suicidal ideation among female Veterans who have experienced MST. We examined whether constructs derived from the interpersonal-psychological theory of suicide (perceived burdensomeness, thwarted belongingness, and fearlessness about death; Joiner, 2005) were associated with suicidal ideation among female Veterans who had experienced MST, when adjusting for known risk factors for suicide. Ninety-two female Veterans with a history of MST completed the Interpersonal Needs Questionnaire, Acquired Capability for Suicide Scale - Fearlessness about Death Scale, and Beck Scale for Suicide Ideation. Perceived burdensomeness, thwarted belongingness, and fearlessness about death were each associated with suicidal ideation in the past week, adjusting for prior suicide attempts, current depressive symptoms, and current symptoms of posttraumatic stress disorder. When including all three interpersonal-psychological constructs in the model, only perceived burdensomeness and fearlessness about death were significantly associated with suicidal ideation. These findings provide knowledge regarding interpersonal processes that may contribute to suicidal ideation among this high-risk, yet understudied, population. These results also underscore the importance of assessing for interpersonal-psychological constructs-particularly perceived burdensomeness and fearlessness about death-when working with female Veterans who have experienced MST. © 2017 Wiley Periodicals, Inc.

    The combat with short-edged weapons has a long tradition in Iran. There are several traditional types of Persian knives and daggers. They can generally be classified into three main categories that were used by Persian warriors in close cambat: kārd (knife), xanjar (dagger), and pišqabz (a type of knife/dagger with an S-shaped blade). The pišqabz was also called dešne. The following article presents these different weapons, analyzing their basic features and variations, the way of carrying an...

  11. Effects of chronic exposure to low doses of ionizing radiation on the reproductive performance and outcome of an exposed population

    Mannino, J.A.

    1978-01-01

    This study was designed to test the hypothesis that low doses of ionizing radiation (cumulative dose less than 5.0 rads/yr) effects the reproductive history and/or outcome of a human population. Medically-related personnel who were exposed to low doses of radiation in the course of their employment were compared with medically-related personnel who were not routinely exposed to ionizing radiation. Each population consisted of 3000 persons from the states of Michigan and Ohio. Reproductive performance, history, and outcome of each sample population was compared statistically. Nineteen congenital defects and 47 postnatal defects were recorded for conceptions of the non-exposed population and 50 congenital defects and 83 postnatal defects were recorded for the exposed group. These groups were further broken down as to whether conception took place before, during, or after exposure and the results statistically analyzed. It was found that the exposure population had greater than expected numbers of postnatal defects and less than expected numbers of normal conceptions

    The Oxford Knee Score (OKS) is a short patient-reported outcome instrument that measures pain and physical activity related to knee osteoarthritis. The purpose of this study is to evaluate, construct validity and consistent reliability of the Persian version of the OKS. The case series consisted of 80 patients who were clinically diagnosed with having knee osteoarthritis. All patients were requested to fill-in the Persian OKS and Short-Form 36 Health Survey (SF-36). Correlation analysis between the Persian versions of these two instruments was then carried out. The scores of the Persian SF-36 were used to evaluate convergent and divergent validity of the 12-item Persian OKS. From a total of 80 patients, 63 were female (79%) and the remaining 17 were male (21%) with a mean age of 52.2 years. In the present study, high Cronbach's alpha of 0.95 confirms excellent internal consistency of the Persian OKS scale similar to previous investigations. The results confirm that the Persian version of this instrument is valid and reliable, similar to its English index and its subsequent translations in different languages. The Persian OKS is a reliable instrument to evaluate knee function in patients with knee osteoarthritis and is a useful tool for outcome measurement in clinical research.

    Although many cross-sectional studies have examined the correlates of psychological resilience in U.S. military veterans, few longitudinal studies have identified long-term predictors of resilience in this population. The current prospective cohort study utilized data from a nationally representative sample of 2157 U.S. military veterans who completed web-based surveys in two waves (2011 and 2013) as part of the National Health and Resilience in Veterans Study (NHRVS). Cluster analysis of cumulative lifetime exposure to potentially traumatic events and Wave 2 measures of current symptoms of posttraumatic stress, major depressive, and generalized anxiety disorders was performed to characterize different profiles of current trauma-related psychological symptoms. Different profiles were compared with respect to sociodemographic, clinical, and psychosocial characteristics. A three-group cluster analysis revealed a Control group with low lifetime trauma exposure and low current psychological distress (59.5%), a Resilient group with high lifetime trauma and low current distress (27.4%), and a Distressed group with both high trauma exposure and current distress symptoms (13.1%). These results suggest that the majority of trauma-exposed veterans (67.7%) are psychologically resilient. Compared with the Distressed group, the Resilient group was younger, more likely to be Caucasian, and scored lower on measures of physical health difficulties, past psychiatric history, and substance abuse. Higher levels of emotional stability, extraversion, dispositional gratitude, purpose in life, and altruism, and lower levels of openness to experiences predicted resilient status. Prevention and treatment efforts designed to enhance modifiable factors such as gratitude, sense of purpose, and altruism may help promote resilience in highly trauma-exposed veterans.

    The use of earths and clays for medical purposes dates back to antiquity. In recent years, there has been an increasing interest in researches on traditional remedies in the hope of discovering new drug. Iran is an ancient country with a medical backbone acquired from the experiences of ancient Persian scholars, who had made a great contribution to the development of the medical sciences. Many medical and pharmaceutical books by early Persian scientists still exist and may have the potential of leading researchers to new drug discoveries. Owing to the emergence of new and antimicrobial-resistant infections, present-day medicine has recently begun focusing on medicinal earths and clays especially as mineral antimicrobials. The current study is, therefore, aimed at gathering information regarding medicinal clays in traditional Persian medicine (TPM). Five main Persian materia medica with the key word 'tin' (clay) and current databases such as PubMed, Scopus, ScienceDirect, and Google Scholar were searched by key words 'white, green, red, maroon, violet, black, grey and pink clays' and 'pharmacological effects'. Twenty three clays were found in Persian manuscripts. Although their mineralogical compositions are unknown, different pharmacological properties have been attributed to these mineral medicaments. Clay's properties were widely used in medieval times for the treatment of infections to poisoning. They were also used in compound formulations, possibly for their pharmaceutical formulation modifying effects. Modern scientific proofs have also been found in many of the medicinal clays reported in Persian manuscripts. Although many of the reported clays are still unknown, their characterization may lead to new medicinal developments. Novel analytical methods available today make it possible to elucidate the chemical compositions of these minerals as parameters responsible for their medicinal effects.

    The purpose of this report is to disseminate information concerning the medical status of 253 Marshallese exposed to fallout radiation in 1954. This report discusses the medical care provided and the medical findings for the years 1988-1991. Details of the BRAVO thermonuclear accident that caused the exposure have been published, and a 1955 article in the Journal of the American Medical Association describing the acute medical effects in the exposed population remains a definitive and relevant description of events. Participation in the Marshall Islands Medical Program by the exposed Marshallese is voluntary. In the spring and fall of each year, medical surveillance is provided to exposed and unexposed cohorts. Examinations performed include: a cancer-related examination as defined by the American Society, an annual thyroid examination and thyroid function testing, serum prolactin testing looking for pituitary tumors, annual blood counts to include platelets, and evaluation for paraneoplastic evidence of neoplasms. This report details the medical program, medical findings, and thyroid surgery findings. Deaths (4 exposed and 10 nonexposed) that occurred during the reporting period are discussed. There is a mild but relatively consistent depression of neutrophil, lymphocyte, and platelet concentrations in the blood of the exposed population. This depression appears to be of no clinical significance. Thyroid hypofunction, either clinical or biochemical, has been documented as a consequence of radiation exposure in 14 exposed individuals. Previously, one other exposed person was diagnosed with basal cell carcinoma. During this reporting period, a thyroid nodule was identified in an individual who was in utero during the exposure. Upon pathologic review, the nodule was diagnosed as occult papillary carcinoma.

    Full Text Available There has been considerable debate over what the sources of morphological variation in second language acquisition are. From among various hypotheses put forth on the topic, the feature reassembly hypothesis (Lardiere, 2005 assumes that it is the reconfiguration of features in the L2 which causes variation between the performance of natives and non-natives. Acknowledged as one of the most difficult elements of English grammar to be acquired by learners, the article system was the focus of the present study which aimed at attending to the acquisition of that system by Persian learners. This descriptive piece of research focused on how the article system functions in English and Persian, the similarities found across the two languages and the possible sources of difficulty for Persian learners in using English articles as related to their L1. The participants included Persian learners at three levels of grammatical knowledge. A group of English native speakers also took part in the study. A grammaticality judgment test and a translation test were conducted to collect data. Comparisons were made among the four groups, using ANOVAs. Based on the results, it is argued that the observed pattern of article use among Persian speaking learners can be best accounted for by the feature reassembly hypothesis.

    A follow-up study of the late effects of intrauterine exposure to irradiation has been made on a 16-year-old girl whose mother was exposed to external 60 Co irradiation during the Xinzhou radiation accident 16 years previously. The outcomes of the general medical examinations, conventional chromosome aberration analyses and fluorescence in situ hybridisation (FISH) are presented and the China-revised Wechsler Intelligence Scale for Children (C W ISC) was used to identify her IQ level, which was well below normal for her age. The biological dose of the radiation to which she was exposed when she was in her mother's uterus was inferred to be 1.85 Gy. Although there is no evidence of any other developmental changes or tumour induction at this stage in her life, the child's total intelligence level does appear to have been affected. (note)

    The Parental Bonding Instrument (PBI) is a widely used self-report measure for quantifying key parenting styles as perceived by the child during its first 16 years. While its development study identified two key parental dimensions, subsequent studies have variably confirmed those two or argued for one or more additional parental constructs. We developed a Persian translation of the PBI and administered it to a sample of 340 high school students. The construct validity of the Persian PBI was examined by Exploratory Factor Analysis while Confirmatory Factor Analysis was used to identify the most adequate model. Analyses of the Persian PBI favored a four-factor model for both parental forms. The Persian PBI has a factorial structure consistent with constructs identified in western cultures, as well as high internal consistency and test-retest reliability. Multivariate analyses indicated significant differences between boys and girls across some factors. The PBI appears an acceptable and appropriate measure for quantifying parent-child bonding in Iranian samples. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Background: Developmental Sentence Scoring (DSS) was developed as a numerical measurement and a clinical method based on the morphosyntactic acquisition in the English language. The aim of this study was to develop a new numerical tool similar to DSS to assess the morphosyntactic abilities in Persian-speaking children. Methods: In this cross-sectional and comparative study, the language samples of 115 typically developing Persian-speaking children aged 30 - 65 months were audio recorded during the free play and picture description sessions. The Persian Developmental Sentence Score (PDSS) and the Mean Length of Utterance (MLU) were calculated. Pearson correlation and one – way Analysis of variance (ANOVA) were used for data analysis. Results: The correlation between PDSS and MLU in morphemes (convergent validity) was significant with a correlation coefficient of 0.97 (p< 0.001). The value Cronbach's Alpha (α= 0.79) in the grammatical categories and the split-half coefficient (0.86) indicated acceptable internal consistency reliability. Conclusion: The PDSS could be used as a reliable numerical measurement to estimate the syntactic development in Persian-speaking children. PMID:28210600

    Although criminal behavior in veterans has been cited as a growing problem, little is known about why some veterans are at increased risk for arrest. Theories of criminal behavior postulate that people who have been exposed to stressful environments or traumatic events and who report negative affect such as anger and irritability are at increased risk of antisocial conduct. We hypothesized veterans with posttraumatic stress disorder (PTSD) or traumatic brain injury (TBI) who report anger/irritability would show higher rates of criminal arrests. To test this, we examined data in a national survey of N = 1,388 Iraq and Afghanistan war era veterans. We found that 9% of respondents reported arrests since returning home from military service. Most arrests were associated with nonviolent criminal behavior resulting in incarceration for less than 2 weeks. Unadjusted bivariate analyses revealed that veterans with probable PTSD or TBI who reported anger/irritability were more likely to be arrested than were other veterans. In multivariate analyses, arrests were found to be significantly related to younger age, male gender, having witnessed family violence, prior history of arrest, alcohol/drug misuse, and PTSD with high anger/irritability but were not significantly related to combat exposure or TBI. Findings show that a subset of veterans with PTSD and negative affect may be at increased risk of criminal arrest. Because arrests were more strongly linked to substance abuse and criminal history, clinicians should also consider non-PTSD factors when evaluating and treating veterans with criminal justice involvement.

    Whether it comes from the ground, the sky, or medical treatment, humans are constantly exposed to ionizing radiation from the world around them. This is a normal occurrence, and has always been the case. According to the IAEA International Basic Safety Standard, the radiation dose for public is not more than 1 mSv per year. That is just an average though, and the actual figure may fluctuate widely per person depending on where they live and the medical procedures they had that year. The international standard is to allow people who work with and around radioactive material (researchers, nuclear power plant workers, X-ray technicians and others) to have exposures of not more than 20 mSv total per year. The 20 mSv annual dose is considered to be safe and not significantly increase the risk for radiation-related health effects. Biological dosimetry based on the analysis of micronuclei in the cytokinesis-block micronucleus (CBMN) assay can be used as an alternative method for scoring dicentric chromosomes in the field of radiation protection. Bio dosimetry is mainly performed, in addition to the physical dosimetry, with the aim of individual dose assessment. The aim of the present study was to perform a cytogenetic analysis in peripheral blood lymphocyte of 30 individuals occupationally exposed to low level of ionizing radiation and compare the result with 30 controls using CBMN assay. Number of bi-nucleated cell and micronuclei were scored and statistical analysis was done to see the effect of micronuclei with gender, age and occupation. In conclusion, scoring of micronuclei is a useful cytogenetic monitoring for radiation workers and assessment of genetic damage. (author)

    Full Text Available Background and Aim: Assessment of central auditory processing skills needs various behavioral tests in format of a test battery. There is a few Persian speech tests for documenting central auditory processing disorders. The purpose of this study was developing a dichotic test formed of one-syllabic words suitable for evaluation of central auditory processing in Persian language children and reporting its preliminary results in a group of normal children.Materials and Methods: Persian words in competing manner test was developed utilizing most frequent monosyllabic words in children storybooks reported in the previous researches. The test was performed at MCL on forty-five normal children (39 right-handed and 6 left-handed aged 5-11 years. The children did not show any obvious problem in hearing, speech, language and learning. Free (n=28 and directed listening (n=17 tasks were investigated.Results: The results show that in directed listening task, there is significant advantage for performance of pre-cued ear relative to opposite side. Right ear advantage is evident in free recall condition. Average performance of the children in directed recall is significantly better than free recall. Average row score of the test increases with the children age.Conclusion: Persian words in competing manner test as a dichotic test, can show major characteristics of dichotic listening and effect of maturation of central auditory system on it in normal children.

    The history of astrology offers to its students a primary challenge: the complexity of its career in transmission from one cultural area to another and in transformation of its doctrines and methods to fit the interests and cultural circumstances of its eager recipients. The translation movement between the Indian and Arabic/Persian cultures is still rarely studied. In this paper I am discussing the relations (intellectual voyages) between Indian and Arabic/Persian astrological traditions from historical and cultural perspectives. By using the various examples from Sanskrit, Pahlavī, Arabic and Persian sources I try to display the intimate scientific exchanges, by emphasizing the field of astrology and divination, between two geographically close, but in a religious and philosophical sense, very different cultural areas. The conclusion is made that the influence of Hindu astro-sciences on Islamic culture was comparatively greater but the impact of the Islamic sciences on Hindus was no less significant. On both sides a fruitful process of enculturation and integration of technical astral concepts and applied methods took place.

    Germline minisatellite mutation rates were investigated in male workers occupationally exposed to radiation at the Sellafield nuclear facility. DNA samples from 160 families with 255 offspring were analysed for mutations at eight hypervariable minisatellite loci (B6.7, CEB1, CEB15, CEB25, CEB36, MS1, MS31, MS32) by Southern hybridisation. No significant difference was observed between the paternal mutation rate of 5.0% (37 mutations in 736 alleles) for control fathers with a mean preconceptional testicular dose of 9 mSv and that of 5.8% (66 in 1137 alleles) for exposed fathers with a mean preconceptional testicular dose of 194 mSv. Subgrouping the exposed fathers into two dose groups with means of 111 mSv and 274 mSv revealed paternal mutation rates of 6.0% (32 mutations in 536 alleles) and 5.7% (34 mutations in 601 alleles), respectively, neither of which was significantly different in comparisons with the rate for the control fathers. Maternal mutation rates of 1.6% (12 mutations in 742 alleles) for the partners of control fathers and 1.7% (19 mutations in 1133 alleles) for partners of exposed fathers were not significantly different. This study provides evidence that paternal preconceptional occupational radiation exposure does not increase the germline minisatellite mutation rate and therefore refutes suggestions that such exposure could result in a destabilisation of the germline that can be passed on to future generations.

    The effects of gamma irradiation (GR) on total phenol, anthocyanin and antioxidant activity were investigated in three different Persian pistachio nuts at doses of 0, 1, 2 and 4 kGy. The antioxidant activity, as determined by FRAP and DPPH methods, revealed a significant increase in the 1-2 kGy dose range. Total phenol content (TPC) revealed a similar pattern or increase in this range. However, when radiation was increased to 4 kGy, TPC in all genotypes decreased. A radiation dose of 1 kGy had no significant effect on anthocyanin content of Kale-Ghouchi (K) and Akbari (A) genotypes, while it significantly increased the anthocyanin content in the Ghazvini (G) genotype. In addition, increasing the radiation to 4 kGy significantly increased the anthocyanin content of K and G genotypes. To conclude, irradiation could increase the phenolic content, anthocyanin and antioxidant activity of pistachio nuts.

    Previous studies have used network models to investigate how PTSD symptoms associate with each other. However, analyses examining the degree to which these networks are stable over time, which are critical to identifying symptoms that may contribute to the chronicity of this disorder, are scarce. In the current study, we evaluated the temporal stability of DSM-5 PTSD symptom networks over a three-year period in a nationally representative sample of trauma-exposed U.S. military veterans. Data were analyzed from 611 trauma-exposed U.S. military veterans who participated in the National Health and Resilience in Veterans Study (NHRVS). We estimated regularized partial correlation networks of DSM-5 PTSD symptoms at baseline (Time 1) and at three-year follow-up (Time 2), and examined their temporal stability. Evaluation of the network structure of PTSD symptoms at Time 1 and Time 2 using a formal network comparison indicated that the Time 1 network did not differ significantly from the Time 2 network with regard to network structure (p = 0.12) or global strength (sum of all absolute associations, i.e. connectivity; p = 0.25). Centrality estimates of both networks (r = 0.86) and adjacency matrices (r = 0.69) were highly correlated. In both networks, avoidance, intrusive, and negative cognition and mood symptoms were among the more central nodes. This study is limited by the use of a self-report instrument to assess PTSD symptoms and recruitment of a relatively homogeneous sample of predominantly older, Caucasian veterans. Results of this study demonstrate the three-year stability of DSM-5 PTSD symptom network structure in a nationally representative sample of trauma-exposed U.S. military veterans. They further suggest that trauma-related avoidance, intrusive, and dysphoric symptoms may contribute to the chronicity of PTSD symptoms in this population. Published by Elsevier B.V.

    The Schizophrenia Cognition Rating Scale (SCoRS) is an interview-based assessment of cognition that involves interviews with patients and informants. The SCoRS has shown good reliability, validity, and sensitivity to cognitive impairment in schizophrenia, with the advantage of brief administration and scoring time. The present study aimed to test the concurrent validity of the Persian version of the SCoRS. A group of 35 patients with schizophrenia and a group of 35 healthy controls received the Persian-SCoRS in the first session, and a standardized performance-based cognitive battery, the Brief Assessment of Cognition in Schizophrenia (BACS), in the second session.Our results indicated that the Persian version of the SCoRS was sensitive to cognitive impairment in the patients. The Persian SCoRS global rating was significantly associated with the composite score generated from the Persian version of the BACS and predicted functional outcomes as measured by Global Assessment of Functioning (GAF) and World Health Organization Quality of Life (WHO QOL). A Persian version of the SCoRS, an interview based measure of cognition that included informants, is related to cognitive performance and global functioning. Copyright © 2017 Elsevier B.V.

  11. Agreement in Persian

    Directory of Open Access Journals (Sweden)

    Lofti, Ahmad R.

    2006-01-01

    Full Text Available This article investigates agreement as a number marking mechanism in Persian. The mechanism differs from number marking on nominals in that with an inanimate plural subject, the SG verbal ending signals a collective conceptualization of the experience where the members of the group are considered together as a single unit. The PL ending, on the other hand, signals a distributive conceptualization where the entities are individuated; hence, they are considered to be dispersed over space, or distinct in sort or time. Autonomy - whether the entity is conceived of as governing the course of events or not - seems to underlie the choice between SG and PL.

    Cytogenetic techniques were used to examine peripheral lymphocytes taken from 33 subjects employed at the IRT-2000-Sofia Nuclear Reactor and exposed to mixed gamma and neutron radiation in its Zone A. Physical dosimetry data (from pen and film personnel dosimeters) showed the exposures to be below maximum permissible levels, in complience with Radiation Safety Norms in the P.R. of Bulgaria (1972). The subjects were distributed into three groups according to the length of their occupational experience as radiation workers. Comparisons were made with cytogenetic findings in the lymphocyte cultures taken from 30 subjects with no occupational radiation exposure. Radiation workers exhibited a significant increase in chromosomal damage of the chromosome and chromatid type. Subjects with 5-10 years of occupational experience had a higher degree of chromosomal damage than the less-than-5-years group. For persons with more than 10 years of occupational experience, however, no increase over controls could be ascertained in percentage of chromosomal damage. When radiation workers were re-distributed in accord with the exposures received, it was evident that the effect increased with the accumulated dose, the group with about 0.02 Sievert having nearly twice the aberrant cell percentage for the 0.01 Sievert group. In the group of up to 0.05 Sievert, the percentage of aberrant cells was in the order of that observed after exposure to 0.02 Sievert. From the findings in the analysis, radiation quality seemed to play no part in enliciting the cytogenetic response of peripheral lymphocytes. (A.B.)

    Objective: To observe and study the late effects of intrauterine exposure to irradiation. Methods: A 16-year-old girl, borne by a woman exposed to 60 Co irradiation during the Xinzhou radiation accident 16 years ago underwent inquiry, general medical examination. Conventional chromosome aberration analysis and fluorescence in situ hybridization (FISH) were used to examine non-stability and stability shromosome aberrations, and China revised Wechsler Intelligence Scale for Children (C W ISC) was used to detect IQ level. Results: Inquiry revealed no history of carcinoma and no family history of hereditary diseases. The girl often caught cold when she was a child, but she hadn't any other diseases. Menarche occurred when she was 12 years old, and she had not suffered from dysmenorrhea. Her development of body frame constitution was normal. She could not carry out addition and subtraction, but she could make simple verbal communication, writing and even reciting text. The results of the routine lab examination were within the normal range. Unstable chromosome aberrations were not shown, and the chromosome translocation rate was 2.3%. The dose that induced the chromosome injury was deduced as 0.81 Gy. The biological dose of the radiation that she was exposed to was inferred to be 1.85 Gy when she was in her mother's uterus. Ultrasonic sound showed nodular goiter and no malignant change. China's revised Wechsler Intelligence Scale for Children (C W ISC) test results showed that speech, operation and full-scale IQ was 51, 50, and 46 respectively. The total intelligence was better than 0.01%, and worse than 99.90% of the population. Conclusions: Exposure in utero does not affect the body frame constitution development after birth of the fetus, but mental retardation is clear. No evidence of any tumor can be found for the children exposed to radiation before their birth. (authors)

    The systemic effect of radiation increases in proportion to the dose amount and rate. The association between accumulated radiation dose and adverse effects, which is derived according to continuous low dose-rate radiation exposure, is not clearly elucidated. Our previous study showed that low dose-rate radiation exposure did not cause adverse effects in BALB/c mice at dose levels of ≤2 Gy, but the testis weight decreased at a dose of 2 Gy. In this study, we studied the effects of irradiation at the low dose rate (3.49 mGy/h) in the testes of C57BL/6 mice. Mice exposed to a total dose of 0.02, 0.2, and 2 Gy were found to be healthy and did not show any significant changes in body weight and peripheral blood components. However, mice irradiated with a dose of 2 Gy had significantly decreased testis weight. Further, histological studies and sperm evaluation also demonstrated changes consistent with the findings of decreased testis weight. In fertile patients found to have arrest of sperm maturation, the seminiferous tubules lack the DNMT1 and HDAC1 protein. The decrease of DNMT1 and HDAC1 in irradiated testis may be the part of the mechanism via which low dose-rate irradiation results in teticular injury. In conclusion, despite a low dose-rate radiation, our study found that when mice testis were irradiated with 2 Gy at 3.49 mGy/h dose rate, there was significant testicular and sperm damage with decreased DNMT1 and HDAC1 expression.

    Full Text Available Background: The Oxford Knee Score (OKS is a short patient-reported outcome instrument that measures pain and physical activity related to knee osteoarthritis. The purpose of this study is to evaluate, construct validity and consistent reliability of the Persian version of the OKS. Methods: The case series consisted of 80 patients who were clinically diagnosed with having knee osteoarthritis. All patients were requested to fill-in the Persian OKS and Short-Form 36 Health Survey (SF-36. Correlation analysis between the Persian versions of these two instruments was then carried out. The scores of the Persian SF-36 were used to evaluate convergent and divergent validity of the 12-item Persian OKS. Results: From a total of 80 patients, 63 were female (79% and the remaining 17 were male (21% with a mean age of 52.2 years. In the present study, high Cronbach’s alpha of 0.95 confirms excellent internal consistency of the Persian OKS scale similar to previous investigations. The results confirm that the Persian version of this instrument is valid and reliable, similar to its English index and its subsequent translations in different languages. Conclusion: The Persian OKS is a reliable instrument to evaluate knee function in patients with knee osteoarthritis and is a useful tool for outcome measurement in clinical research.

    This study examined the diagnostic accuracy of selected language sample measures (LSMs) with Persian-speaking children. A pre-accuracy study followed by phase I and II studies are reported. Twenty-four Persian-speaking children, aged 42 to 54 months, with primary language impairment (PLI) were compared to 27 age-matched children without PLI on a set of measures derived from play-based, conversational language samples. Results showed that correlations between age and LSMs were not statistically significant in either group of children. However, a majority of LSMs differentiated children with and without PLI at the group level (phase I), while three of the measures exhibited good diagnostic accuracy at the level of the individual (phase II). We conclude that general LSMs are promising for distinguishing between children with and without PLI. Persian-specific measures are mainly helpful in identifying children without language impairment while their ability to identify children with PLI is poor.

    Abstract Purpose of the Study: To compare the number of chronic conditions among a list of 12 and their association with physical function among postmenopausal non-Veteran and Veteran women with diabetes. Design and Methods: Among women with diabetes from the Women’s Health Initiative, we compared the average number of chronic conditions between non-Veterans and Veterans and the association between total number of chronic conditions on subsequent RAND-36 physical function. To examine associations between each condition and subsequent physical function, we compared women with diabetes plus one chronic condition to women with diabetes alone using linear regression in separate models for each condition and for non-Veterans and Veterans. Results: Both non-Veterans ( N = 23,542) and Veterans ( N = 618) with diabetes had a median of 3 chronic conditions. Decreases in physical function for each additional condition were larger among Veterans than non-Veterans (−6.3 vs. −4.1 points). Decreases in physical function among women with diabetes plus one chronic condition were greater than that reported for diabetes alone for all combinations and were more pronounced among Veterans (non-Veterans: −11.1 to −24.2, Veterans: −16.6 to −40.4 points). Hip fracture, peripheral artery disease, cerebrovascular disease, and coronary disease in combination with diabetes were associated with the greatest decreases in physical function. Implications: Chronic conditions were common among postmenopausal women with diabetes and were associated with large declines in physical function, particularly among Veterans. Interventions to prevent and reduce the impact of these conditions and facilitate coordination of care among women with diabetes may help them maintain physical function. PMID:26768385

    Full Text Available The combat with short-edged weapons has a long tradition in Iran. There are several traditional types of Persian knives and daggers. They can generally be classified into three main categories that were used by Persian warriors in close cambat: kārd (knife, xanjar (dagger, and pišqabz (a type of knife/dagger with an S-shaped blade. The pišqabz was also called dešne. The following article presents these different weapons, analyzing their basic features and variations, the way of carrying and unsheathing them, and the corresponding techniques of use of each weapon.

    Almost two-thirds of proven oil and a third of world natural gas resources are in the Persian Gulf countries. Unfortunately strategic region of Persian Gulf in the past three decades faced with many security challenges due to wars and political conflicts. For security in this region, there are several methods such as military treaties between regional countries or Military presence of foreign countries, but historical evidence has shown, none of them could not guarantee the stable security in this region. The regional cooperation between countries can be replaced to mentioned methods. IPI Gas pipeline is an objective sample for this regional cooperation.

    The mollusc Biomphalaria glabrata have characteristics that allow them to be identified as an animal model ideal for monitoring areas exposed to chemical agents and physical. This study evaluated the effect of ionizing radiation from Cobalt-60 in haemocytes present in the hemolymph of Biomphalaria glabrata, with the goal of using these cells as indicators of the presence of radiation in aquatic environments. The mollusks were divided into five groups: one control and four subjected doses of 25, 35, 45 and 55 Gy of gamma radiation. After 48 hours of irradiation, the clam hemolymph was collected and slides were prepared and stained with Giemsa for analyses under a light microscope. Statistical analysis was performed using ANOVA and Tukey's test, p <0.05. The results showed that the total number of cells after irradiation reduced compared to control except at a dose of 55 Gy. During data analysis, morphological changes were observed in haemocytes of mollusks subjected to doses of 35, 45 and 55 Gy. These modifications consisted of nucleus bilobulated and nucleo plasmatic bridges. Another change was exclusively observed in the cellular exposure of 55 Gy, where hemocytes showed misshapen nuclei and cytoplasm vacuolisation, suggestive of apoptosis. It is concluded that hemocytes are sensitive to radiation and can be used as indicators of the presence of high doses of ionizing radiation in aquatic environments. (author)

  3. Gender, race & the veteran wage gap.

    Vick, Brandon; Fontanella, Gabrielle

    2017-01-01

    This paper analyzes earnings outcomes of Iraq/Afghanistan-era veterans. We utilize the 2009-2013 American Community Survey and a worker-matching methodology to decompose wage differences between veteran and non-veteran workers. Among fully-employed, 25-40 year-olds, veteran workers make 3% less than non-veteran workers. While male veterans make 9% less than non-veterans, female and black veterans experience a wage premium (2% and 7% respectively). Decomposition of the earnings gap identifies some of its sources. Relatively higher rates of disability and lower rates of educational attainment serve to increase the overall wage penalty against veterans. However, veterans work less in low-paying occupations than non-veterans, serving to reduce the wage penalty. Finally, among male and white subgroups, non-veterans earn more in the top quintile due largely to having higher educational attainment and greater representation in higher-paying occupations, such as management.

    Healthcare systems are interested in technology-enhanced interventions to improve patient access and outcomes. However, there is uncertainty about feasibility and acceptability for groups who may benefit but are at risk for disparities in technology use. Thus, we sought to describe characteristics of Internet use and technology-related attitudes for two such groups: (1) Veterans with multi-morbidity and high acute care utilization and (2) informal caregivers of Veterans with substantial care needs at home. We used survey data from two ongoing trials, for 423 Veteran and 169 caregiver participants, respectively. Questions examined Internet use in the past year, willingness to communicate via videoconferencing, and comfort with new technology devices. Most participants used Internet in the past year (81% of Veterans, 82% of caregivers); the majority of users (83% of Veterans, 92% of caregivers) accessed Internet at least a few times a week, and used a private laptop or computer (81% of Veterans, 89% of caregivers). Most were willing to use videoconferencing via private devices (77-83%). A majority of participants were comfortable attempting to use new devices with in-person assistance (80% of Veterans, 85% of caregivers), whereas lower proportions were comfortable "on your own" (58-59% for Veterans and caregivers). Internet use was associated with comfort with new technology devices (odds ratio 2.76, 95% confidence interval 1.70-4.53). Findings suggest that technology-enhanced healthcare interventions are feasible and acceptable for Veterans with multi-morbidity and high healthcare utilization, and informal caregivers of Veterans. In-person assistance may be important for those with no recent Internet use.

    The aim of this study was to evaluate the psychometric properties of the Persian version of the International Consultation on Incontinence Modular Questionnaire for Female Lower Urinary Tract Symptoms (ICIQ-FLUTS) in patients with urinary tract dysfunction. After gaining permission from the International Consultation on Incontinence Modular Questionnaire (ICIQ) advisory board, the English Female Lower Urinary Tract Symptoms (FLUTS) questionnaire was translated into Persian and then translated back into English. One hundred fourteen women with pelvic floor dysfunction were asked to complete the Persian FLUTS and International Consultation on Incontinence Modular Questionnaire Overactive Bladder Questionnaire (ICIQ-OAB). The Persian FLUTS questionnaire was also readministered to 20 patients 2 weeks after their initial visit. Study data were analyzed using SPSS V16.0. To validate the translated questionnaire, we assayed content/face validity, internal consistency/reliability, and construct validity. Internal consistency and test-retest reliability were assessed using Cronbach's alpha and the intraclass correlation coefficient (ICC) respectively. The mean age of the patients was 48.8 years old, 84% were married, and 59% had at least one Caesarean. Except for very few missing data, there is no any ambiguity in the Persian version of the FLUTS questionnaire. The Cronbach's alpha was 0.83, indicating a high internal consistency. Concerning criterion validity, correlation between the Persian FLUTS and the OAB was 0.77 (p Persian version of the FLUTS questionnaire demonstrates good internal consistency, content validity, and reliability.

    This study explored the dynamics of veteran/service dog partnerships by gathering the perspectives of veterans with a history of post-traumatic stress disorder and/or traumatic brain injury. Exploratory qualitative methods (focus groups and individual interviews) were used to investigate veteran/service dog relationships related to community involvement, family and friend relationships, self-care, work, and leisure. Nine male veterans, Paws, and Stripes program graduates participated. Data were audio recorded and transcribed by two research team members who used qualitative analytic software to manage and code the data. The full research team discussed themes and reached consensus on the themes that emerged from analysis. Five themes emerged about the perceived benefit of veteran/service dog relationship: Secluded but Seeking Society (moving from isolation to reconnection); Opening Opportunities (navigating daily life); Bridging the Gap (facilitating social opportunities); and Reclaiming Life (transforming sense of worth and purpose). An overarching theme, Calming Catalyst, connected the other four themes. Veterans in this study reported that their goal was to reclaim and develop key aspects of their lives and they perceived service dogs as a support in their transition from isolation to reintegration. This study found that service dogs supported the veterans to meet their goal. Implications for rehabilitation There are a significant number of veterans with post-traumatic stress disorder and/or traumatic brain injury who are facing life challenges including self-care, securing work, participating in leisure activities, and integrating into the community. Service dogs are an emerging intervention used to assist veterans with reintegration into civilian life. There is a need for professionals to be aware of potential benefits of service dog/veteran partnerships. Based on our findings, veterans could benefit from being paired with a service dog to facilitate their

    In this study, we reported the reliability and validity of Bedside version of Persian WAB (P-WAB-1) adapted from Western Aphasia Battery (WAB-R) (1,2). P-WAB-1 is a clinical linguistic measuring tool to determine severity and type of aphasia in brain damaged patients based on Aphasia Quotient (AQ) as a functional measure. For the purposes of a quick clinical screening of aphasia in Persian, we adapted the bedside version of WAB-R to assess the performance of Persian aphasic patients. The data we reported on adaptation, validity and reliability of P-WAB-1 are based on faithful translation and criterion validity ratio (CVR) taken from the expert panel and the performance of 60 consecutive brain damaged patients referred to different university clinics for rehabilitation and 30 healthy subjects as norms and 40 age-matched epileptic patients as the control group. Based on the results of this study, P-WAB-1 has internal consistency (a=0.71) and test-retest reliability (r=.65 PPersian speaking brain damaged patients. This study is the initial step on adaptation of different versions of WAB-R to measure the severity of aphasia using AQ, LQ and CQ as operational measures and to classify Persian speaking aphasic patients into different types.

    Full Text Available Toxocara cati is among the most common feline parasites which can infect human especially children and cause various symptoms. Due to close connection of this species with humans as pets and with other stray cats either directly or indirectly; this study was conducted specially for the first time to determine the infection status of Persian cats of Tabriz area to this parasite. In this study, from a total of 50 Persian cats studied, 13 (26% were infected by a variety of enteric parasites and 37 (74% were without infection and 10 (20% of the cats were infected by Toxocara cati. According to the results, significant difference in infection rate was observed between Persian cats kept indoors and those that were kept in cattery and also there was significant differences in infection rate between males and females (p

    The hazardous effects of ionizing radiation to man are well recognized, and they are divided into two groups, the stochastic effects (hereditary and carcinogenic effect) and non-stochastic effects (somatic effects such as depression of hematopoiesis, chronic dermatitis and cataracta). The basic framework of the International Commission on Radiological Protection (ICRP) is intended to prevent the occurrence of non-stochastic effects, by keeping doses below the relevant thresholds, and to ensure that all reasonable aspects are taken to reduce the incidence of stochastic effects. In Japan, the regulatory provisions of radiological protection of the workers occupationally exposed to ionizing radiation are based on the recommendation of ICRP adopted in 1977. According to these regulations, the dose equivalent limits of occupational exposure of man has been decided at 50 mSv/year. The monitoring of exposure to the individual and the procedure of medical examination of the workers are briefly described and discussed. (author)

    Since 2003 The Janbazan Medical and Engineering Research Center in collaboration with Tehran University has conducted a nationwide cancer registry project among all Iranian Veterans with history of exposure to mustard gas during 1980-1988 Iran Iraq war. The mixed cohort study has a retrospective phase from the exposure time to 2003 and a prospective phase from 2003 to 2013. The main goal is to find any possible relationship between exposure to mustard gas and developing cancer as a long term health effect. A total number of 7500 individual (both military and civilians) with confirmed medical records of exposure to mustard gas have been included in the study to be compared with the same number of control population as well as the statistics of the national cancer registry system. The follow up of all cases is being done as a part of the national health monitoring program of the Janbazan (veterans) organization. In this report the latest findings of this project will be presented.(author)

    Objective: One of the most common global disorders is related to gastrointestinal system. Functional dyspepsia (FD) defined as upper abdominal pain and discomfort in the absence of organic ailments is a prevalent disease without any confirmed medication. The purpose of this study was to find gastric disorders which might be coincidental to FD based on traditional Persian medicine (TPM). Materials and Methods: We searched the main textbooks of TPM including Al-Havi (by Rhazes), Canon of medicine (by Avicenna), ZakhireKhawrazmshahi (by Ismail Jorjani), Moalijat-e Aghili and Makhzan Al-adviya (by Mohammad Hosein AghiliShirazi), and ExirAzam (by Hakim Azam Khan). Also, we searched Pubmed, Scopus, Science Direct, Medline, scientific information database (SID), Iranmedex and Google Scholar from 1980 to 1 August 2014 for dyspepsia, gastrointestinal disease, traditional Persian medicine, and gastric dystemperaments. Results: There is no equivalent term for FD in traditional Persian medicine although similar signs and symptoms are visible in terms like simple cold dystemperament of stomach, indigestion, and digestion debility in TPM sources. Some treatments mentioned in TPM have shown promising results in the current experimental tests. Conclusion: Finding these similarities in complementary and alternative medicine (CAM) textbooks may lead to discovering new remedies for this widespread disease. PMID:27222829

    The Brief Assessment of Cognition in Schizophrenia (BACS) is designed for assessment of cognitive function in patients with schizophrenia. Versions of the BACS in English and other languages have been shown to be as sensitive to cognitive dysfunction as a standard test battery, with the advantage of brief administration and scoring time. The present study aimed to test the concurrent validity of the Persian version of the BACS (Persian-BACS). A group of 50 patients with schizophrenia-spectrum disorders and a group of 50 healthy controls received the Persian-BACS in a first session, and in a second session a standard neurocognitive battery. Cronbach's alpha for the Persian-BACS was 0.74. All the Persian-BACS subscales were significantly correlated with the corresponding standard neurocognitive subscales and the Pearson correlation of the composite scores from the two instruments was 0.71. Moreover, a one-factor solution was found that accounted for 67.9% of the variance. Finally, the Persian-BACS demonstrated high ability to discriminate patients with schizophrenia from healthy controls. Good psychometric properties of the Persian-BACS suggest that it is a useful tool for assessing cognition in schizophrenic patients with Persian as their primary language. © 2013 The Authors.

    Methods: The effect of addition of Persian gums, Tragacanth, and a combination of both of these compounds at levels of 0.5, 1, and 1.5% on texture, color, and sensory characteristics of these cakes was evaluated in this study. Results: The results showed that solidity and viscosity factors were elevated by addition of gum to cake. Using of gums in cakes leads to moisture maintenance inside the cake texture and thus improves mastication property. Furthermore, the results of porosity evaluation showed that addition of Persian gums and Tragacanth decreases the size and increases the number of gas cells inside the cake texture and improves porosity. The best porosity was related to the sample containing 1.5% Persian gum and Tragacanth. The treatment that contained 0.75% Persian gum and 0.75% Tragacanth had the highest acceptability among consumers. Conclusions: Results showed that Persian and Tragacanth gums, whether used independently or in combination, can improve the quality and organoleptic characteristics of gluten-free cakes.

    Tuberculosis was a major cause of morbidity and manpower loss in the Armed Forces during World War II. Military control programmes commenced in the 1950s but were initially limited in scope by the many recruits who were already tuberculin positive on enlistment. The aim of our study was to examine whether veterans have an increased risk of tuberculosis compared with non-veterans. Retrospective cohort study of 57 000 veterans born 1945-1985, and 173 000 people with no record of military service, resident in Scotland, matched for age, sex and area of residence, using Cox proportional hazard analysis to compare the risk of tuberculosis overall, by birth cohort, length of service and year of diagnosis and to examine comorbidities. Over mean 29 years follow-up, 69 (0.12%) veterans were recorded as having tuberculosis, compared with 267 (0.15%) non-veterans (unadjusted HR 0.90, 95% CIs 0.69 to 1.19, p=0.463). Only the 1945-1949 veterans' birth cohort was at higher risk, unadjusted HR 1.54, 95% CIs 0.98 to 2.45, p=0.061, although the difference in risk did not achieve significance. Veterans born from 1950 were at significantly reduced risk of tuberculosis compared with non-veterans after adjusting for deprivation, HR 0.67, 95% CI 0.47 to 0.95, p=0.026. The most common comorbidities were smoking-related and alcohol-related disease. The risk of comorbid hepatitis B or C was very low, in both veterans and non-veterans. No length of service was associated with an increased risk of tuberculosis in comparison with non-veterans. Scottish veterans born before 1950 are at moderately increased risk of tuberculosis compared with age, sex and geographically matched civilians with no record of service, although the difference is not statistically significant. Scottish veterans born from 1950 show a reduction in risk compared with civilians. Tuberculosis should be considered in the differential diagnosis of respiratory disease in the older veteran.

    The current study was undertaken to examine whether posttraumatic stress symptoms (PTSS) and depressive symptoms mediated the association between trauma exposure (combat-related trauma and non-combat traumas occurring before, during, and after military service), and drug abuse symptoms use among male and female veterans. Participants were 2304 (1851 male, 453 female) veterans who took part in a multi-site research study conducted through the Department of Veterans Affairs Mid-Atlantic Mental Illness Research, Education and Clinical Center (VISN 6 MIRECC). Path analytic models were used to determine the association between problematic past-year drug use and combat-related and non-combat trauma experienced before, during, or after the military and whether current post-traumatic stress symptoms or depressive symptoms mediated these associations. For both male and female veterans, depressive symptoms significantly mediated the effects of pre- and post-military trauma on drug abuse symptoms. Mental health providers who work with trauma-exposed Iraq and Afghanistan era veterans should assess for drug use, depressive symptoms, and life-span trauma (i.e., not only combat-related traumas) as part of a thorough trauma-based assessment for both men and women.

    The object of this work is to introduce the training program in Radiation Protection implemented in our Hospital, and its evaluation and follow-up. Material AND Methods: The training program in Radiation Protection implanted by the Department of Radiation Protection in the Hospital de la Ribera consists of three types of training modalities: Annual Seminars: applicable to all the exposed workers and divided in a general part and a specific one for each area; Informative lectures: applicable to a specific department, deal with specific issues of interest without predetermined frequency; Individualised training: applicable to pregnant, new workers, job moves and duties change. The follow-up of the program is carried out by mean of inquiries about general and site-specific knowledge on radiation protection. Results The results of the inquiries are analysed and related with the continuous training program. Conclusion: It is remarkable that departments with workers without academic training in radiation protection (Intensive Care Unit, Surgery, Endoscopy,) need a more dedicated training. The results confirm the validity of the three training modalities: The annual seminar provides a continuous training to all exposed workers; the informative lecture is useful to handle immediately issues of current interest in a specific department and the individual training are useful to acquire specific knowledge about radiation risks and radiation protection rules in new working situations.

    Data were summarized on the DNA Bank establishment for workers of the Mayak nuclear facility in Southern Ural, who were exposed to different doses of chronic radiation from γ -rays during the first years of the enterprise operations (1948-1958) and their families. Some workers were exposed to combined radiation (external + internal radiation from incorporated 239 Pu). The DNA Bank was established to store the unique genetic material from these individuals and their offspring for future risk estimation of the late consequences of radiation exposure using modern molecular-genetic technologies. Today, DNA Bank contains genetic material from 1,500 individuals and 218 families. The computer database was generated for the DNA Bank. It included individual medical-demographic, occupational descriptions and doses, quantitative and qualitative DNA data. Literature data on radiation-induced genome instability (variability of hypervariable areas) were also analyzed. Prospects of the DNA Bank establishment are also presented. The work is carried out on extension of the DNA Bank of exposed individuals and their offspring

    Full Text Available As an important feature of interface between language and society, address terms can provide valuable sociolinguistic information about the interlocutors, their relationship and their circumstances. As a result, in the past few decades address terms in different languages have been studied from different angles and with varying focus. In line with those studies this article focuses on identifying different types of addressing terminology that Persian interlocutors may use in different contexts. Personal names, general and occupation titles, kinship related terms, religious oriented expressions, honorifics, terms of intimacy, personal pronouns, descriptive phrases and employing greetings or attention getters to avoid address terms were found to be the possible categories for Persian addressers choice. The study also reveals that Persian language is rich enough in this respect and that an artful skill is required for Persian speakers to make an accurate and proper use of the vast range of choices for addressing individuals in various contexts. In addition to account for the abandonment of certain socioeconomic-referenced terms, the study also shows a number of culture-specific address terms which may have no equivalent in English.

    The peripheral blood content in women, which, due to their occupation are exposed to low dose ionizing radiation effect, has been investigated. One hundred and ten women from 20 to 50 years of age and occupation service in a sphere of ionizing radiation from 6 months to 4 years (an average length of 2,5 years) were examined. The unequal external gamma irradiation was the fundamental factor of the radiation effect under conditions of occupational media. The mean annual dose did never exceed the maximum permissible limits. As control, a group of 106 clinically healthy women of the same age and working in the industry but not exposed to radiation effect, was formed. Hemoglobin quantity, erythrocytes and leukocytes number, differential count of leukocytes and thrombocytes number were analyzed. Not any statistically significant differences (p > 0,05) between the mean values of the studied parameters of the control group and this one of women exposed to occupational irradiation were observed. This analysis of the hematological parameters represents the first stage of the already undertaken dynamic examination of the health status of a new and relatively stable contingent of occupationally irradiated persons.

    The feeling of abdominal fullness, bloating, and movement of gas in the abdomen is a very uncomfortable sensation termed flatulence. Since flatulence is one of the most common gastrointestinal symptoms that is bothersome to patients, it is important to identify effective methods to resolve this issue. In modern medicine, management of flatulence is often not satisfactory. On the other hand, traditional systems of medicine can be considered good potential sources to find new approaches for preventing and treating flatulence. The aim of this study is to review flatulence treatments from a traditional Persian medicine (TPM) viewpoint. In this study, the reasons for flatulence and methods for its prevention and treatment are reviewed in traditional Persian medicine (TPM) texts and then related with evidence from modern medicine by searching in databases, including PubMed, Scopus, Google Scholar, and IranMedex. From a traditional Persian scholar viewpoint, one of the most important causes of flatulence is an incorrect manner of eating; valuable advice to correct bad eating habits will be illustrated. In addition, traditional practitioners describe some herbs and vegetables as well as herbal compounds that are effective food additives to relieve flatulence. The anti-flatulent effect of most of these herbs has been experimentally verified using modern medicine. Attention to TPM can lead to the identification of new preventive and curative approaches to avoid and treat flatulence. In addition, Persian viewpoints from the medieval era regarding flatulence are historically important.

    Full Text Available BACKGROUND: The present study aims to design and standardize the verbal fluency test (VFT among bilingual (Turkish-Persian adolescents in Tabriz, Iran. METHODS: In the designing stage, 190 adolescents who were already selected randomly from among the guidance and high school students in Tabriz were classified into three age groups (11-12, 13-15, 16-18. The screening test including 33 Persian letters and three ‘animal’, ‘fruit’, and ‘supermarket stuff’ categories, and SDQ was administered to them. The results were the three letters ‘M’, ‘D’, and ‘B’ for phonological fluency, and two ‘animal’ and ‘supermarket stuff’ categories for semantic fluency in the Persian language. In the standardization stage, the letters and categories specified in the designing stage were administered in the same order to 302 adolescents. Moreover, 28 adolescents diagnosed with ADHD were selected to estimate the discriminant validity of VFT. RESULTS: Pearson correlation coefficient between test-retest of the three letters ‘M’, ‘D’, and ‘B’ for phonological fluency were estimated at 0.67, 0.66, and 0.75, respectively. Furthermore, for the two categories of ‘animal’ and ‘supermarket stuff’ it was estimated to be 0.80 and 0.65, respectively. All these amounts were significant (P < 0.01. The discriminant validity, which was estimated through comparison between the scores of normal and ADHD adolescents, showed that the obtained t value for all indices except for the letter ‘B’ was meaningful. The results of MANOVA between two gender groups were significant at P < 0.05 for three ‘M’, ‘D’, and ‘B’ variables of verbal fluency and ‘animal’ semantic fluency. In both verbal and semantic fluency the mean of subjects’ performance scores showed that females outperformed males. CONCLUSIONS: The findings of the current study indicated that VFT is reliable in the studied sample group, and has a valid psychometric

    Persian bamboo shark (Chiloscyllium arabicum) was collected from two sites of the Khozestan province, northern basin of Persian Gulf, with the aim to identify differences in metal concentrations between fishing areas as well as the risk for human health due to consumption of the selected species. We analyzed Zn, Cu, Pb, Hg, Cd and Ni in muscle and liver tissues of specimens from both areas of study using atomic adsorption spectrometry. Statistical elaborations revealed higher bioaccumulation of metals in livers than muscle as well as in the site of worthy of Musa as regards Zn, Pb and Ni than the site of worthy of Darvis, due to the more intensive anthropogenic input. The risk for consumers is low for the most of metals, with the exception of the THQ for Hg, which resulted next to the level of risk with high frequencies of consumption.

    In a survey it will be given results of consultations of pregnant women exposed during the pregnancy in the period of 1976 to 1992 formerly in the National Board of Atomic Safety and Radiation Protection of the GDR and since 1990 in the Clinic-diagnostical Division of the Federal Health Office. The report includes dose estimations of the embryo and medical assessments of 430 pregnant women. The radiation exposure were mainly received by X-ray diagnostic (n = 406 cases) and the others by applications of radiation in nuclear medicine, research and vocational training (n = 24 cases). Results of dose and risk estimation were summarized in tables. Women having incurred fetal doses in excess of 100 mGy were recommended to interrupt pregnancy. A fetal dose above 100 mGy occured in 9 cases. The anatomico-pathological and embryological findings of the embryo or fetus showed only in one case a reference of teratogenic radiation damage.

    In his seminal book on the historical periods of Western attitudes toward death, Philippe Aries describes four consecutive periods through which these attitudes evolved and transformed. According to him, the historical attitudes of Western cultures have passed through four major parts described above: "Tamed Death," One's Own Death," "Thy Death," and "Forbidden Death." This paper, after exploring this concept through the lens of Persian Poetic Wisdom, concludes that he historical attitudes of Persian-speaking people toward death have generally passed through two major periods. The first period is an amalgamation of Aries' "Tamed Death" and "One's Own Death" periods, and the second period is an amalgamation of Aries' "Thy Death" and "Forbidden Death" periods. This paper explores the main differences and similarities of these two historical trends through a comparative review of the consecutive historical periods of attitudes toward death between the Western and Persian civilizations/cultures. Although both civilizations moved through broadly similar stages, some influential contextual factors have been very influential in shaping noteworthy differences between them. The concepts of after-death judgment and redemption/downfall dichotomy and practices like deathbed rituals and their evolution after enlightenment and modernity are almost common between the above two broad traditions. The chronology of events and some aspects of conceptual evolutions (such as the lack of the account of permanent death of nonbelievers in the Persian tradition) and ritualistic practices (such as the status of the tombs of Shiite Imams and the absolute lack of embalming and wake in the Persian/Shiite culture) are among the differences.

    Background Over one hundred different pharmaceutical dosage forms have been recorded in literatures of Traditional Persian Medicine among which nasal forms are considerable. Objectives This study designed to derive the most often applied nasal dosage forms together with those brief clinical administrations. Materials and Methods In the current study remaining pharmaceutical manuscripts of Persia during 9th to 18th century AD have been studied and different dosage forms related to nasal application of herbal medicines and their therapeutic effects were derived. Results By searching through pharmaceutical manuscripts of medieval Persia, different nasal dosage forms involving eleven types related to three main groups are found. These types could be derived from powder, solution or liquid and gaseous forms. Gaseous form were classified into fumigation (Bakhoor), vapor bath (Enkebab), inhalation (Lakhlakheh), aroma agents (Ghalieh) and olfaction or smell (Shomoom). Nasal solutions were as drops (Ghatoor), nasal snuffing drops (Saoot) and liquid snuff formulations (Noshoogh). Powders were as nasal insufflation or snorting agents (Nofookh) and errhine or sternutator medicine (Otoos). Nasal forms were not applied only for local purposes. Rather systemic disorders and specially CNS complications were said to be a target for these dosage forms. Discussion While this novel type of drug delivery is known as a suitable substitute for oral and parenteral administration, it was well accepted and extensively mentioned in Persian medical and pharmaceutical manuscripts and other traditional systems of medicine as well. Accordingly, medieval pharmaceutical standpoints on nasal dosage forms could still be an interesting subject of study. Therefore, the current work can briefly show the pharmaceutical knowledge on nasal formulations in medieval Persia and clarify a part of history of traditional Persian pharmacy. PMID:24624204

  11. Determination of intake and internal radiation dose for occupationally exposed workers to iodine 131

    Workers who prepare and inject radioactive Iodine I 131 doses at the medical centers in Syria are potentially exposed to the radioactive intake by ingestion or inhalation during preparation or injection processes. The received amount of the radioactive intake differs according to the amount of the I 131 that released during the preparation or injection processes, and to the work conditions and the applying ways of the radiation protection principles. Because of this radioactive intake, the thyroid gland may expose to amounts of I 131 which may negatively affect the health of the workers, so it is necessary to make routine monitoring for all workers who receive an intake of more than 10% of the annual intake limit which is (2*10 6 Bq/y) for I 131 . To make this monitoring process, it is necessary to use either the thyroid gland counter in order to know the concentrated amount of the radioactivity in the gland, or the analysis of a 24 hours urine sample of the exposed workers to determine the eliminated amount of the radioactivity using gamma spectrometry, also the two processes can be applied at the same time. Since the thyroid gland counter is not available, the analysis of urine sample was done to determine the concentrated amount of the radioactivity in urine, then to estimate the radioactive intake and the internal radioactive dose. The results of applying this method dictated that some workers work in safe conditions according to the radiation protection and there is no need for them to make routine monitoring . But the other workers receive a radioactive intake of about 10% yearly of the annual intake limit and that requires a routine periodical monitoring for those workers in addition to the necessity of applying the principles of the radiation protection during the work with I 131 . These principles and systems should indicate the basic requirement of radiation protection that must be available in the laboratory that deal with I 131 either for therapy or for

    STS-45 Earth observation taken aboard Atlantis, Orbiter Vehicle (OV) 104, is of the northern reaches of the Persian Gulf with the sunglint pattern centered on the Saudi Arabian island of Abu Ali. Bright features along the coast are thought to be deposits of oil, released from a terminal offshore of Kuwait during the recent Persian Gulf War. Further up the coast, in Kuwait, the black, oil-soaked desert surrounding the site of the oil well fires is clearly visible. View was taken from an altitude of 160 nautical miles with OV-104 located at 28 degrees north and 52.8 degrees east. During the STS-45 mission, an international survey team focused on oil contamination of the shallow-water habitants in the area north of Abu Ali Island. Crewmembers contacted the NOAA survey vessel, the R/V Mt. Mitchell, several times and photographed water color and sunglint within the study area and throughout the entire Persian Gulf. These photographic data are expected to aid the Persian Gulf researchers in

    In 1954, following detonation of a megaton nuclear device at Bikini, an unfortunate accident occurred owing to an unpredicted shift in winds resulting in exposure to radioactive fallout of 250 Marshallese people, 28 American servicemen on atolls to the east, and 23 Japanese fishermen on their fishing vessel. In this presentation, medical findings in the exposed Marshallese noted over the past 28 years is briefly reviewed with particular emphasis on late effects on the thyroid gland. The Marshallese were too far distant from the detonation for any direct effects, and their exposure was due entirely to fallout radiation during the 2 days prior to evacuation. This consisted of penetrating whole-body gamma radiation, irradiation of the skin (principally beta radiation) from fallout deposited on the skin, and internal absorption of radionuclides from ingestion of contaminated food and water. The most serious internal exposure was that to the thyroid from radioiodines, which were relatively abundant in the fallout. 63 references, 1 figure, 4 tables

    To translate and cross-culturally adapt the Functional Independence Measure (FIM) into the Persian language and to test the reliability and validity of the Persian FIM (PFIM) in patients with stroke. In this cross-sectional study carried out in an outpatient stroke rehabilitation center, 40 patients with stroke (mean age 60 years) were participated. A standard forward-backward translation method and expert panel validation was followed to develop the PFIM. Two experienced occupational therapists (OTs) assessed the patients independently in all items of the PFIM in a single session for inter-rater reliability. One of the OTs reassessed the patients after 1 week for intra-rater reliability. There were no floor or ceiling effects for the PFIM. Excellent inter-rater and intra-rater reliability was noted for the PFIM total score, motor and cognitive subscales (ICC(agreement)0.88-0.98). According to the Bland-Altman agreement analysis, there was no systematic bias between raters and within raters. The internal consistency of the PFIM was with Cronbach's alpha from 0.70 to 0.96. The principal component analysis with varimax rotation indicated a three-factor structure: (1) self-care and mobility; (2) sphincter control and (3) cognitive that jointly accounted for 74.8% of the total variance. Construct validity was supported by a significant Pearson correlation between the PFIM and the Persian Barthel Index (r = 0.95; p Persian patients with stroke. The Functional Independence Measure (FIM) is an outcome measure for disability based on the International Classification of Functioning, Disability and Health (ICF). The FIM was cross-culturally adapted and validated into Persian language. The Persian version of the FIM (PFIM) is reliable and valid for assessing functional status of patients with stroke. The PFIM can be used in Persian speaking countries to assess the limitations in activities of daily living of patients with stroke.

  18. Relations Between Cognitive Functioning and Alcohol Use, Craving, and Post-Traumatic Stress: An Examination Among Trauma-Exposed Military Veterans With Alcohol Use Disorder.

    Cognitive dysfunction is commonly observed among individuals with alcohol use disorder (AUD) and trauma exposure and is, in turn, associated with worse clinical outcomes. Accordingly, disruptions in cognitive functioning may be conceptualized as a trans-disease phenomenon representing a potential high-yield target for intervention. Less is known though about how different cognitive functions covary with alcohol use, craving, and post-traumatic stress symptom severity among trauma-exposed individuals with AUD. Sixty-eight male and female trauma-exposed military veterans with AUD, entering treatment trials to reduce alcohol use, completed measures assessing alcohol use and craving, post-traumatic stress symptom severity, and cognitive functioning. In multivariate models, after controlling for post-traumatic stress symptom severity, poorer learning and memory was associated with higher alcohol consumption and higher risk taking/impulsivity was associated with stronger preoccupations with alcohol and compulsions to drink. Alcohol consumption and craving, but not performance on cognitive tests, were positively associated with post-traumatic stress symptom severity. Findings suggest that interventions to strengthen cognitive functioning might be used as a preparatory step to augment treatments for AUD. Clinicians are encouraged to consider a standard assessment of cognitive functioning, in addition to post-traumatic stress symptom severity, in treatment planning and delivery for this vulnerable and high-risk population.

    Studies of radiation induced defects continue to be relevant as they find an ever greater application due to the increasing radiation doses to which semiconductor detectors are exposed. Efforts of figuring out the changes due to high radiation doses provide the fundamental motivation for this type of experiments. The PIN diode is described, and a developmental disorder caused thereto by 60Co source gamma quanta ranging from 100 kGy to 1 MGy. The calibration curve shows the effect of disturbances on the volt-ampere characteristics as a function of the dose of gamma radiation. The results are compared with earlier published data. Highlights: •We have studied Si PIN diode dosimeters irradiated by gamma. •We measured DLTS spectra and calculated energy traps caused by gamma irradiation. •Increasing dose caused creation of new traps and disappearance of others.

    In the studies reported here, the micronucleus assay, a common cytogenetic technique, was used to examine the dose-responses in fibroblasts from three ungulate species (white-tailed deer, woodland caribou, and Indian muntjac) exposed to high doses of ionizing radiation (1-4 Gy of 60 Co gamma radiation). This assay was also used to examine the effects of exposure to low doses (1-100 mGy) typical of what these species experience in a year from natural and anthropogenic environmental sources. An adaptive response, defined as the induction of resistance to a stressor by a prior exposure to a small 'adapting' stress, was observed after exposure to low doses. This work indicates that very small doses are protective for the endpoint examined. The same level of protection was seen at all adapting doses, including 1 radiation track per cell, the lowest possible cellular dose. These results are consistent with other studies in a wide variety of organisms that demonstrate a protective effect of low doses at both cellular and whole-organism levels. This implies that environmental regulations predicated on the idea that even the smallest dose of radiation carries a quantifiable risk of direct adverse consequences to the exposed organism require further examination. Cytogenetic assays provide affordable and feasible biological effects-based alternatives that are more biologically relevant than traditional contaminant concentration-based radioecological risk assessment

    The Revised Fibromyalgia Impact Questionnaire (FIQR), an updated version of the Fibromyalgia Impact Questionnaire (FIQ) achieved a better balance among different domains (i.e., function, overall impact, and symptom severity) and attempts to address the limitations of FIQ. As there is no Persian version of the FIQR available, we aimed to investigate the validity and reliability of a Persian translation of the FIQR in Iranian patients. After translating the FIQR into Persian, it was administered to 77 female patients with fibromyalgia syndrome. All of the patients filled out the questionnaire together with a Persian version of the FIQ, short form-12 (SF-12). The tender-point count was also calculated. One week later, FM patients filled out the Persian FIQR at their second visit. Reliability was analyzed by internal consistency and reproducibility including Cronbach's α coefficient and intra-class correlation coefficient. Construct validity was evaluated by Spearman's correlation coefficient and Pearson's correlation coefficient. Statistical analysis was performed using SPSS for Windows version 17.0. All patients included in this study were female, and the mean age was 38.23 ± 10.68 years. The total scores of the FIQR and FIQ were 49.77 ± 18.27 and 54.05 ± 14.00 that were closely correlated (r = 0.63, p FIQ domains (r = 0.36-0.63, p fibromyalgia.

    This report describes a historical cohort study of the group of Canadian military personnel exposed to radiation in the 1950s at atomic bomb test blasts in the U.S. and Australia, and at clean-up operations at the Chalk River Nuclear Laboratories. Overall and cause-specific mortality in the exposed group was compared to that of the control cohort of unexposed military personnel, matched on age, service, rank and trade. Analyses indicated no elevation in the exposed cohort, in overall or cause-specific mortality due to diseases associated with radiation. Since this study was restricted to an investigation of mortality, we must stress that we cannot generalize these results or conclusions to current morbidity experienced by the exposed cohort

    Eating disorders are understudied among male veterans, who may be at increased risk due to the high rates of trauma exposure and experiences of multiple traumatization in this population. This study sought to examine the associations between specific types of trauma (i.e., childhood physical abuse, adult physical assault, childhood sexual abuse, adult sexual assault, and military-related trauma) and eating disorder symptoms in a large, nationally-representative sample of trauma-exposed male veterans. Survey data were collected from N = 642 male veterans. Traumatic experiences in childhood and adulthood were assessed using the Trauma History Screen and the National Stressful Events Survey. Eating disorder symptoms were assessed with the Eating Disorder Diagnostic Scale. Analyses also controlled for age and body mass index. Multiple traumatization was associated with increased eating disorder symptoms. However, military-related trauma was the only trauma type that was uniquely associated with eating disorder symptoms when controlling for other trauma types. Examination of different types of military-related trauma indicated that this association was not driven by exposure to combat. Noncombat, military-related trauma was associated with eating disorder symptom severity in male veterans. Results highlight the need for better assessment of eating disorder symptoms in this population. © 2017 Wiley Periodicals, Inc.

    Emerging knowledge suggests that post-traumatic stress disorder (PTSD) pathophysiology is linked to the patients’ epigenetic changes, but comprehensive studies examining genome-wide methylation have not been performed. In this study, we examined genome-wide DNA methylation in peripheral whole blood in combat veterans with and without PTSD to ascertain differentially methylated probes. Discovery was initially made in a training sample comprising 48 male Operation Enduring Freedom (OEF)/Operation Iraqi Freedom (OIF) veterans with PTSD and 51 age/ethnicity/gender-matched combat-exposed PTSD-negative controls. Agilent whole-genome array detected ~5600 differentially methylated CpG islands (CpGI) annotated to ~2800 differently methylated genes (DMGs). The majority (84.5%) of these CpGIs were hypermethylated in the PTSD cases. Functional analysis was performed using the DMGs encoding the promoter-bound CpGIs to identify networks related to PTSD. The identified networks were further validated by an independent test set comprising 31 PTSD+/29 PTSD− veterans. Targeted bisulfite sequencing was also used to confirm the methylation status of 20 DMGs shown to be highly perturbed in the training set. To improve the statistical power and mitigate the assay bias and batch effects, a union set combining both training and test set was assayed using a different platform from Illumina. The pathways curated from this analysis confirmed 65% of the pool of pathways mined from training and test sets. The results highlight the importance of assay methodology and use of independent samples for discovery and validation of differentially methylated genes mined from whole blood. Nonetheless, the current study demonstrates that several important epigenetically altered networks may distinguish combat-exposed veterans with and without PTSD. PMID:28696412

    There is a growing need for information on evidence-based practices that may potentially address needs of elderly people with severe mental illness (SMI), and more specifically on community-based services such as assertive community treatment (ACT). This study examines national evaluation data from fiscal year 2001-2005 from Veterans Affairs Mental Health Intensive Case Management (MHICM) program (N = 5,222), an ACT-based service model, to characterize the age distribution of participants and the distinctive needs, patterns of service delivery, and treatment outcomes for elderly veterans. Altogether, 24.8% of participants were 55-64 years; 7.4% 65-74 years; and 2.8% were older than 75. Veterans over 75 formed a distinct subgroup that had a later age of onset of primarily nonpsychotic illnesses without comorbid substance abuse and had experienced more limited lifetime hospital treatment than younger participants. Older veterans were less symptomatic and more satisfied with their social relationships than younger clients. They mostly live independently or in minimally restrictive housing, but they received less recovery-focused services and more crisis intervention and medical services. They thus do not appear to be young patients with SMI who have aged but rather constitute a distinct group with serious late-onset problems. It is possible that MHICM services keep them in the community and avoid costly nursing home placement while providing a respite service that reduces family burden. These data highlight the unique characteristics of older veterans receiving ACT-like services and the need to focus greater attention on recovery-oriented services as well as community support for this subgroup.

    Full Text Available Objectives: Increasingly people are using the internet to find information about medical and educational issues and one of the simplest ways to obtain information is internet. Persian Cued Speech is a very new system to Iranian families with deaf child and the professionals and a few educators have enough knowledge about it, so the purpose of this study was to introduce Persian Cued Speech website to deaf educators and rehabilitation professionals and assess their views about the website and their accessibility to important information through its use. Methods:The sample group was randomly selected fromdeaf educators and rehabilitation professionals working in different educational settings for deaf children in Tehran, our capital .They completed a questionnaire which was adopted from different website assessing questionnaires. Researchers also completed an interview with the sample group. Results: Our findings show that from the deaf educators and rehabilitation professionals point of view,the Persian Cued Speech website was a helpful and informing website. They also wanted more pictures and videos,bigger font sizes and more practical parts.So we decide to change some parts of the website to be more usable for them. Discussion: Using informational websites can be a very helpful tool in the internet area. Helpful websites are those which are more accessible, readable and appropriately designed and are user-friendly.

    Full Text Available Coral bleaching events due to elevated temperatures are increasing in both frequency and magnitude worldwide. Mass bleaching was recorded at five sites in the northern Persian Gulf during August and September 2012. Based on available seawater temperature data from field, satellite and previous studies, we suggest that the coral bleaching threshold temperature in the northern Persian Gulf is between 33.5 and 34°C, which is about 1.5 to 2.5°C lower than that in the southern part. To assess the bleaching effects, coral genera counted during 60-minute dives were categorized into four groups including healthy, slightly bleached ( 50% bleached tissue and fully bleached colonies. The anomalously high sea surface temperature resulted in massive coral bleaching (~84% coral colonies affected. Acropora spp. colonies, which are known as the most vulnerable corals to thermal stress, were less affected by the bleaching than massive corals, such as Porites, which are among the most thermo-tolerant corals. Turbid waters, suggested as coral refugia against global warming, did not protect corals in this study since most affected corals were found in the most turbid waters. The 2012 bleaching in the northern Persian Gulf was relatively strong from the viewpoint of coral bleaching severity. Long-term monitoring is needed to understand the actual consequences of the bleaching event on the coral reefs and communities.

  12. Gastrointestinal drug absorption in rats exposed to 60Co γ-radiation

    1976-01-01

    Following exposure of the gastrointestinal (GI) tract to ionizing radiation, its structure and function are altered for several days. Such alterations may affect the bioavailability of orally administered drugs. The potential mechanisms by which radiation may affect drug absorption were explored by studying the absorption of four test drugs, sulfanilamide, bretylium, sulfisoxazole acetyl, and riboflavin, in rats that were exposed to 850 R cobalt-60 gamma-radiation or sham irradiated. In one series of experiments, the drugs were administered orally and the amount of drug excreted in urine was used as a measure of the extent of their absorption. Cumulative urinary excretion of the drugs was shown to be a valid measure of absorption since it was not affected by radiation after intravenous administration of the drugs. At one day post-irradiation, the extent of absorption of sulfanilamide and bretylium was not affected by radiation but the absorption of sulfisoxazole acetyl and riboflavin was increased. At five days post-irradiation, there was no detectable difference between irradiated and control animals in the extent of absorption of the drugs. The fraction of sulfanilamide excreted in the urine as 4 N-conjugate was increased at one day post-irradiation. The increased excretion of metabolite appeared to result from metabolism of the drug by gut flora prior to absorption. This study shows that radiation-induced alterations in the absorption of orally administered drugs are due primarily to slowed gastric emptying. In general, slowed gastric emptying causes the rate of drug absorption to decline. The extent of absorption of drugs that are normally well absorbed is not affected by radiation while the extent of absorption of drugs that normally are absorbed poorly may be increased after irradiation of the GI tract

    "Melancholia" seems to be the oldest term used to describe the manifestations of depression. Throughout the history of medicine, melancholia has been the focus of consideration of many scholars who have provided varying definitions of this disorder and its manifestations. This continual process has resulted in the gradual development of the concept of melancholia over time. Persian scholars were among the scientists who have studied the melancholia and contributed to its concept. One figure, Al-Akhawayni Bukhari (?-983 AD), a Persian physician whose reputation was based on the treatment of patients with mental problems, investigated this disorder. He described Melancholia and explained its clinical manifestations and treatment methods. Al-Akhawayni provided an early classification of the patients suffering from this disorder. Since the medieval Persian concept of melancholia is not well-known, this paper aims to review Al-Akhawayni's 10(th) century knowledge on melancholia which can represent the early concept of this disorder in the Near East.

    In this study, the phase behavior of sodium caseinate-Persian gum mixtures was investigated. The effect of thermodynamic incompatibility on phase distribution of sodium caseinate fractions as well as the flow behavior and microstructure of the biopolymer mixtures were also studied. The phase diagram clearly demonstrated the dominant effect of Persian gum on the incompatibility of the two biopolymers. SDS-PAGE electrophoresis indicated no selective fractionation of sodium caseinate subunits between equilibrium phases upon de-mixing. The microstructure of mixtures significantly changed depending on their position within the phase diagram. Fitting viscometric data to Cross and Bingham models revealed that the apparent viscosity, relaxation time and shear thinning behavior of the mixtures is greatly influenced by the volume ratio and concentration of the equilibrium phases. There is a strong dependence of the flow behavior of sodium caseinate-Persian gum mixtures on the composition of the equilibrium phases and the corresponding microstructure of the system.

    2008-05-01

    Full Text Available This study aspires to examine the concept of ellipsis by comparing and contrasting English and Persian written texts. For this purpose, three Persian novels and three English ones were selected. These novels were analyzed carefully; they were compared and contrasted for types and amount of ellipsis used, through a Chi-square analysis.  The results of the data analysis revealed that various types of ellipsis were used differently in these two languages. In other words, in the English corpus, nominal ellipsis was used more frequently than verbal ellipsis but in the Persian one, the use of verbal ellipsis was more frequent than nominal. Moreover, the results of this study lend some support to the idea of the universality of ellipsis, in that, all subtypes of ellipsis were used in these two languages although they  were used more frequently in English than in Persian. This study might have implications for teachers, material developers, and researchers in the field of teaching English as a foreign language. In other words, teaching ellipsis directly to foreign language learners will improve the quality of their writing. Moreover,  the results of the present study have obvious importance in increasing students' awareness of the way native speakers of English organize their writing.

    One of the main effects of the Chernobyl reactor accident is an increase in childhood papillary thyroid carcinomas (PTC) in the regions that were contaminated with radio-iodine from the fallout. Despite a considerable research effort, molecular profiles have yet to be identified that reliably distinguish between age matched patients with radiation associated and sporadic PTCs. Expression of micro RNAs (miRNA) have recently been studied extensively in many different cancer types. MiRNAs have the potential to provide insights into the network of molecular pathways that are involved in the development of tumorigenesis as they are involved in the regulation of networks of mRNAs. In addition, miRNAs can be studied in formalin-fixed paraffin embedded material, making them ideal for clinical studies. This study was designed specifically to identify differentially expressed miRNAs in patients with childhood PTC that were exposed (n=11) and non-exposed (n=9) to irradiation. The results suggest that in radiation-associated childhood PTC DNA repair processes which are reflected by genes that encode DNA-binding proteins are de-regulated. DNA mutation and double-strand breaks are induced by ionising radiation and subsequent mis-repair and inactivation of tumour suppressor genes and the activation of oncogenes leads to growth and proliferation of the tumour cell. These findings suggest that in addition to the MAP kinase pathway which is known to be a key pathway in PTC, additional pathways such as the Fc epsilon RI signalling, the VEGF pathway and p53 signalling pathway seem to be involved in radiation-associated tumorigenesis of PTC

    The exposure of man to radiation and the resulting risk of carcinogenesis continue to be of concern to the public. In this context, there is often a tendency to carry out epidemiological studies concerning the induction of cancer in radiation workers and members of the public which are not supported by a statistically valid data base or whose result are misinterpreted or misused. To assist national authorities in evaluating radiological risks, the Nuclear Energy Agency has sponsored a critical review of the methodologies for, and the limitations of, these epidemiological studies, and of the precautions to be adopted in interpreting their results. Prepared by two consultants, Dr. Joan M. Davies and Dr. Hazel Inskip, the review focuses on the problems encountered when carrying out epidemiological studies on groups of the general population exposed to radiation, and using their results for radiological protection purposes. The primary objective is to provide background material for national authorities who have responsibilities in the field of radiological protection, as well as to other persons interested in this subject.

    Cross-sectional validation study to investigate psychometric properties of adapted Persian version of the Scoliosis Research Society-22r (SRS-22r) questionnaire. OBJECTIVES.: To translate the SRS-22r into Persian and to evaluate the internal consistency, reliability, and validity of the Persian SRS-22r. The SRS-22r has not been translated and validated for Persian-speaking patients with idiopathic scoliosis. This was to provide a validated instrument to measure health-related quality of life in patients with idiopathic scoliosis in Iran. The translation and cultural adaptation of the original questionnaire were carried out in accordance with the published guidelines. About 84 patients with adolescent idiopathic scoliosis were participated in the study. The Short Form Health Survey (SF-36) was used to test convergent validity of the Persian SRS-22r. Moderate to high correlations were found between the SRS-22r domains and SF-36 subscales. The correlations ranged from 0.54 to 0.67 (function/activity domain), 0.48 to 0.74 (pain domain), 0.45 to 0.55 (self image domain), 0.66 to 0.85 (mental health domain), and 0.35 to 0.55 (satisfaction domain) (P adolescent patients with scoliosis in Iran. It is simple and easy to use and now can be applied in clinical settings and future outcome studies in Iran.

    Highlights: • Irradiation increased intestinal bacterial translocation, accompanied by claudin protein expression in rats. • Neurotensin decreased the bacterial translocation and restored claudin-3 expression. • Claudin-3 can be used as a marker in evaluating radiation induced intestinal injury. - Abstract: The molecular events leading to radiation-induced intestinal barrier failure are not well known. The influence of the expression of claudin proteins in the presence and absence of neurotensin was investigated in radiation-exposed rat intestinal epithelium. Wistar rats were randomly divided into control, irradiation, and irradiation + neurotensin groups, and bacterial translocation to the mesenteric lymph node and expression of claudins were determined. Irradiation led to intestinal barrier failure as demonstrated by significant bacterial translocation. In irradiated terminal ilea, expression of claudin-3 and claudin-4 was significantly decreased, and claudin-2 expression was increased. Administration of neurotensin significantly reduced bacterial translocation and restored the structure of the villi as seen by histologic examination. Among the three subtype of claudins, only claudin-3 expression was restored. These results suggest that the therapeutic effect of neurotensin on the disruption of the intestinal barrier is associated with claudin-3 alteration and that claudin-3 could be used as a marker in evaluating radiation-induced intestinal injury.

    Diabetes Mellitus is a common metabolic disorder presenting increased amounts of serum glucose and will cover 5.4% of population by year 2025. Accordingly, this review was performed to gather and discuss the stand points on diagnosis, pathophysiology, non-pharmacological therapy and drug management of diabetes this disorder as described in medieval Persian medicine. To this, reports on diabetes were collected and analyzed from selected medical and pharmaceutical textbooks of Traditional Persian Medicine. A search on databases as Pubmed, Sciencedirect, Scopus and Google scholar was also performed to reconfirm the Anti diabetic activities of reported herbs. The term, Ziabites, was used to describe what is now spoken as diabetes. It was reported that Ziabites, is highly associated with kidney function. Etiologically, Ziabites was characterized as kidney hot or cold dystemperament as well as diffusion of fluid from other organs such as liver and intestines into the kidneys. This disorder was categorized into main types as hot (Ziabites-e-har) and cold (Ziabites-e-barid) as well as sweet urine (Bole-e-shirin). Most medieval cite signs of Ziabites were remarked as unusual and excessive thirst, frequent urination and polydipsia. On the management, life style modification and observing the essential rules of prevention in Persian medicine as well as herbal therapy and special simple manipulations were recommended. Current investigation was done to clarify the knowledge of medieval scientists on diabetes and related interventions. Reported remedies which are based on centuries of experience might be of beneficial for- further studies to the management of diabetes. PMID:24741508

    Full Text Available Given that a systematic treatment of Persian Discourse Markers (hereafter DMs is almost absent in modern Persian linguistics and to bridge this gap, the audio-recorded data comprising 14 face to face casual conversations involving two-party and multi-party interactions among family members, acquaintances and close friends are used to shed light on these ‘frequently used’ but ‘frequently unnoticed’ linguistic elements. To document a list of the most common DMs typically used in Tehrani dialect of Persian language and to have a detailed description of their discoursal functions in talk, Brinton’s (1996 binary classification of DMs functions (textual and interpersonal was developed to provide an empirically-supported account of the functions and position of Persian DMs in interaction among Tehrani speakers. The present account of DMs which is basically ‘analytical description’ provides the reader with the knowledge about how Persian DMs operate in actual usage. The findings are built upon a 3105-word corpus including 14 audio-recorded conversations among 50 participants. Altogether 34 tokens of Persian DMs with an overall 254 occurrences were identified among which na/na baba (no/no daddy with the total of 33 (12.84% occurrences were the most frequently used Persian DM in the data which are followed by dige (no English equivalent, aare/ba’ale (yep/yes, yani (I mean, vali (but, haalaa/ alaan (now, bebin/nega kon (look and aslan (by no means/ never.To the author, research on the functions and distributional patterns of Persian DMs will broaden our knowledge of their discoursal behavior in language in general and contribute to the already growing cross-linguistic body of work on DMs.

Rheological (farinograph and extensograph characteristics, staling, and organoleptic evaluations were performed on the dough and the resulting Taftoon bread. Statistical results showed that the salep gum at 5% and Persian gum at 3% (w/w flour basis had a significant effect on the dough properties. Salep and Persian gums when each separately added increased and decreased dough water absorption, respectively. Both hydrocolloids increased the dough resistance to extension and decreased its extensibility. Persian gum shows dual nature in water absorption and some other baking properties. Textural studies revealed that addition of 5% salep gum (w/w flour basis reduced the bread crumb firmness and delayed the staling process of the Taftoon bread. X-ray diffraction study also confirmed this result.

  8. Military veterans and Social Security.

    Olsen, Anya

    There are 9.4 million military veterans receiving Social Security benefits, which means that almost one out of every four adult Social Security beneficiaries has served in the United States military. In addition, veterans and their families make up almost 40 percent of the adult Social Security beneficiary population. Policymakers are particularly interested in military veterans and their families and have provided them with benefits through several government programs, including Social Security credits, home loan guarantees, and compensation and pension payments through the Department of Veterans Affairs. It is therefore important to understand the economic and demographic characteristics of this population. Information in this article is based on data from the March 2004 Current Population Survey, a large, nationally representative survey of U.S. households. Veterans are overwhelmingly male compared with all adult Social Security beneficiaries who are more evenly split between males and females. Military veterans receiving Social Security are more likely to be married and to have finished high school compared with all adult Social Security beneficiaries, and they are less likely to be poor or near poor than the overall beneficiary population. Fourteen percent of veterans receiving Social Security benefits have income below 150 percent of poverty, while 25 percent of all adult Social Security beneficiaries are below this level. The higher economic status among veterans is also reflected in the relatively high Social Security benefits they receive. The number of military veterans receiving Social Security benefits will remain high over the next few decades, while their make-up and characteristics will change. In particular, the number of Vietnam War veterans who receive Social Security will increase in the coming decades, while the number of veterans from World War II and the Korean War will decline.

    The study was aimed at investigation of the parameters of physical development and specific features in the development of psychomotor habits and peripheral blood parameters in children aged 0 to 7 grandchildren of exposed individuals. A dynamic follow-up of physical and psychomotor development, as well as regular check-ups of peripheral blood were carried out in 877 grandchildren of test subjects occupationally exposed to chronic radiation before conception. Multifactorial analysis did not show a correlation between the deviations in the physical development of children in the studied cohort and exposure of their grandparents and/or parents. Factors other than radiation (poor health status of mother, gestosis) did influence the studied parameters. The mean levels of hemoglobin, red cells, platelets, and leukocytes in the test group were virtually the same as in controls and coincided with published data [ru

    Frequently and in an increasing perspective, the Brazilian Nuclear Energy Commission is inquired on the development of cancer in occupationally exposed workers to ionizing radiation. These workers try to compensate their state of ill health juridically. Taking into account that cancer is a probabilistic effect of radiation, it could be only detected by an increase in cases that normally occur in a particular population. Whether or not the occurrence of the illness is identified as having occupational origin misses scientific consistence. Regarding the probabilistic effect of low level radiation doses, radiation protection is founded on the linear dose-effect without threshold hypothesis. Thus, it could be call into a question: is it possible that the illness, presented by an individual, derives from occupational causes. If the answer is positive, the responsibility can be imputed, at first, to the employer and the link of causality turns out to be fundamented not any more in measurable objective facts but in social, economic, ethic and moral aspects, which arise from the radiological protection quality and measures offered by the employer.

    Pineal gland is one of the most important components of homeostasis - the supporting system of the body. It participates in the launch of stress responses, restriction of their development, prevention of adverse effects on the body. There was proved an impact of electromagnetic radiation on the epiphysis. However, morphological changes in the epiphysis under exposure to electromagnetic radiation of modern communication devices are studied not sufficiently. For the time present the population is daily exposed to electromagnetic radiation, including local irradiation on the brain. These date determined the task of this research - the study of the structure of rat pineal gland under the exposure to electromagnetic radiation from personal computers and mobile phones. These date determined the task of this research - the study of the structure of rat pineal gland under the exposure to electromagnetic radiation from personal computers and mobile phones. Performed transmission electron microscopy revealed signs of degeneration of dark and light pinealocytes. These signs were manifested in the development of a complex of general and specific morphological changes. There was revealed the appearance of signs of aging and depletion transmission electron microscopy both in light and dark pinealocytes. These signs were manifested in the accumulation of lipofuscin granules and electron-dense "brain sand", the disappearance of nucleoli, cytoplasm vacuolization and mitochondrial cristae enlightenment.

    The aim was to culturally translate and validate the Persian lower extremity functional scale (LEFS) in a heterogeneous sample of outpatients with lower extremity musculoskeletal disorders (n = 304). This is a prospective methodological study. After a standard forward-backward translation, psychometric properties were assessed in terms of test-retest reliability, internal consistency, construct validity, dimensionality, and ceiling or floor effects. The acceptable level of intraclass correlation coefficient >0.70 and Cronbach's alpha coefficient >0.70 was obtained for the Persian LEFS. Correlations between Persian LEFS and Short-Form 36 Health Survey (SF-36) subscales of Physical Health component (rs range = 0.38-0.78) were higher than correlations between Persian LEFS and SF-36 subscales of Mental Health component (rs range = 0.15-0.39). A corrected item--total correlation of >0.40 (Spearman's rho) was obtained for all items of the Persian LEFS. Horn's parallel analysis detected a total of two factors. No ceiling or floor effects were detected for the Persian LEFS. The Persian version of the LEFS is a reliable and valid instrument that can be used to measure functional status in Persian-speaking patients with different musculoskeletal disorders of the lower extremity. Implications for Rehabilitation The Persian lower extremity functional scale (LEFS) is a reliable, internally consistent and valid instrument, with no ceiling or floor effects, to determine functional status of heterogeneous patients with musculoskeletal disorders of the lower extremity. The Persian version of the LEFS can be used in clinical and research settings to measure function in Iranian patients with different musculoskeletal disorders of the lower extremity.

    Full Text Available Jalal al-Din Rumi and Muhammad Hafez Shirazi are two of the great mystics, Sufis, writing in Persian in the 13th and 14th century. Their poetry is still an essential part of the Turkish and the Persian religious and cultural settings. The objectives of this article are to suggest a method for analyzing the poetry of Rumi and Hafez within the discipline of History of religions. The various combinations of symbols, symbolic clusters, together create a totality from which parts are taken and combined in various ways in the poems. Seldom all of them are there together, but reading some poems with various themes gives the whole combination of symbols, which has been used by the poet. It gives the picture of a Sufi setting, where the essential thing is the path to the unity with God. With it goes the Persian identity indicated in the garden of roses symbolizing paradise, kingship, justice, prosperity, the love of nature etc. Only in combination do these symbols point to the complex situation of the Persian Sufis.

    All living organisms are naturally exposed to radiation from different sources. Ionizing radiation produces a plethora of lesions upon DNA that can be categorized as single and double strand breaks and base damage. Among them, unrepaired double strand breaks (Dbs) have the greatest biological significance, since they are responsible of cell death. In Escherichia coli this kind of lesions are repaired mostly by homologous recombination. In this work the participation of some recombination genes in the repair of Dbs is evaluated. Escherichia coli defective strains were exposed to gamma radiation and incubated for different periods in ideal conditions. Both micro electrophoresis and pulse field gel electrophoresis techniques were used to evaluate the kinetics of repair of such lesions, reflecting the importance of each defective gene in the process.

    Carpal tunnel syndrome (CTS) is recognized as the most common type of neuropathies. Questionnaires are the method of choice for evaluating patients with CTS. Boston Carpal Tunnel Syndrome (BCTS) is one of the most famous questionnaires that evaluate the functional and symptomatic aspects of CTS. This study was performed to evaluate the validity and reliability of the Persian version of BCTS questionnaire. First, both parts of the original questionnaire (Symptom Severity Scale and Functional Status Scale) were translated into Persian by two expert translators. The translated questionnaire was revised after merging and confirmed by an orthopedic hand surgeon. The confirmed questionnaire was interpreted back into the original language (English) to check for any possible content inequality between the original questionnaire and its final translated version. The final Persian questionnaire was answered by 10 patients suffering from CTS to elucidate its comprehensibility; afterwards, it was filled by 142 participants along with the Persian version of the Quick-DASH questionnaire. After 2 to 6 days, the translated questionnaire was refilled by some of the previous patients who had not received any substantial medical treatment during that period. Among all 142 patients, 13.4 % were male and 86.6 % were female. The reliability of the questionnaire was tested using Cronbach's alpha and Intraclass correlation coefficient (ICC). Cronbach's alpha was 0.859 for symptom severity scale (SSS) and 0.878 for functional status scale (FSS). Also, ICCs were calculated as 0.538 for SSS and 0.773 for FSS. In addition, construct validity of SSS and FSS against QuickDASH were 0.641 and 0.701, respectively. Based on our results, the Persian version of the BCTQ is valid and reliable. Level of evidence: II.

    Veterans of the 1991 Gulf War have an increased risk of amyotrophic lateral sclerosis (ALS), but the etiology is unknown. This study sought to identify geographic areas with elevated risk for the later development of ALS among military personnel who served in the first Gulf War. A unified geographic information system (GIS) was constructed to allow analysis of secondary data on troop movements in the 1991 Gulf War theatre in the Persian Gulf region including Iraq, northern Saudi Arabia, and Kuwait. We fit Bayesian Poisson regression models to adjust for potential risk factors, including one relatively discrete environmental exposure, and to identify areas associated with elevated risk of ALS. We found that service in particular locations of the Gulf was associated with an elevated risk for later developing ALS, both before and after adjustment for branch of service and potential of exposure to chemical warfare agents in and around Khamisiyah, Iraq. Specific geographic locations of troop units within the 1991 Gulf War theatre are associated with an increased risk for the subsequent development of ALS among members of those units. The identified spatial locations represent the logical starting points in the search for potential etiologic factors of ALS among Gulf War veterans. Of note, for locations where the relative odds of subsequently developing ALS are among the highest, specific risk factors, whether environmental or occupationally related, have not been identified. The results of spatial models can be used to subsequently look for risk factors that follow the spatial pattern of elevated risk.

    People use many different coping strategies to deal with their traumatic recollections. Twenty-five British World War II veterans were interviewed regarding the ways they used social support both during the war and in the years afterwards. The findings demonstrate that social support is used in fundamentally different ways. During the war comradeship was particularly important and even fifty years after the war comrades are still a valuable resource for discussing war experiences, and dealing with the emotional content of traumatic recollections. Veterans rely on wives and families to help deal with the more physical and practical elements of coping, but tend not to discuss their traumatic memories with them. The findings show that social support is an important lifelong coping strategy for World War II veterans.

    Complete text of publication follows. The health concerns have been raised following the enormous increase in the use of wireless mobile telephones through out the world. This investigation had been taken, with the motive to find out whether mobile phone radiations cause any in vivo effects on the frequency of micronucleated exfoliated cells in the exposed subjects. A total of 109 subjects including 85 regular mobile phone users (exposed) and 24 non-users (controls) had participated in this study. Exfoliated cells were obtained by swabbing the buccal-mucosa from exposed as well as sex-age-matched controls. One thousand exfoliated cells were screened from each individual for nuclear anomalies including micronuclei (MN), karyolysis (KL), karyorrhexis (KH), broken egg (BE) and bi-nucleated (BN) cells. The average daily duration of exposure to mobile phone radiations is 61.26 minutes with an overall average duration of exposure in term of years is 2.35 years in exposed subjects along with the 9.84±0.745 MNC (micronucleated cells) and 10.72±0.889 TMN (total micronuclei) as compared to zero duration of exposure along with average 3.75±0.774 MNC and 4.00±0.808 TMN in controls. The means are significantly different in case MNC and TMN at 0.01% level of significance. For all other nuclear anomalies (KL, KH, BE and BN cells) the means are found statistically nonsignificant. A positive correlation was found in the frequency of MNC and TMN with respect to duration of exposure time.

    The purpose of the present study was to translate and to cross-culturally adapt the Cumberland Ankle Instability Tool (CAIT) into Persian language and to evaluate its psychometric properties. The International Quality of Life Assessment process was pursued to translate CAIT into Persian. Two groups of Persian-speaking individuals, 105 participants with a history of ankle sprain and 30 participants with no history of ankle sprain, were asked to fill out Persian version of CAIT (CAIT-P), Foot and Ankle Ability Measure (FAAM), and Visual Analog Scale (VAS). Data obtained from the first administration of CAIT were used to evaluate floor and ceiling effects, internal consistency, dimensionality, and criterion validity. To determine the test-retest reliability, 45 individuals re-filled CAIT 5-7 days after the first session. Cronbach's alpha was over the cutoff point of 0.70 for both ankles and in both groups. The intra-class correlation coefficient was high for right (0.95) and left (0.91) ankles. There was a strong correlation between each item and the total score of the CAIT-P. Although the CAIT-P had strong correlation with VAS, its correlation with both subscales of FAAM was moderate. The CAIT-P has good validity and reliability and it can be used by clinicians and researchers for identification and investigation of functional ankle instability. Implications for Rehabilitation Chronic ankle instability is one of the most common consequences of acute ankle sprain. Cumberland Ankle Instability Tool is an acceptable measure to determine functional ankle instability and its severity. The Persian version of Cumberland Ankle Instability Tool is a valid and reliable tool for clinical and research purpose in Persian-speaking individuals.

    Military sexual trauma (MST) is the Veteran Health Administration's (VHA) term for sexual assault and/or sexual harassment that occurs during military service. The experience of MST is associated with a variety of mental health conditions. Preliminary research suggests that MST may be associated with homelessness among female Veterans, although to date MST has not been examined in a national study of both female and male homeless Veterans. To estimate the prevalence of MST, examine the association between MST and mental health conditions, and describe mental health utilization among homeless women and men. National, cross-sectional study of 126,598 homeless Veterans who used VHA outpatient care in fiscal year 2010. All variables were obtained from VHA administrative databases, including MST screening status, ICD-9-CM codes to determine mental health diagnoses, and VHA utilization. Of homeless Veterans in VHA, 39.7 % of females and 3.3 % of males experienced MST. Homeless Veterans who experienced MST demonstrated a significantly higher likelihood of almost all mental health conditions examined as compared to other homeless women and men, including depression, posttraumatic stress disorder, other anxiety disorders, substance use disorders, bipolar disorders, personality disorders, suicide, and, among men only, schizophrenia and psychotic disorders. Nearly all homeless Veterans had at least one mental health visit and Veterans who experienced MST utilized significantly more mental health visits compared to Veterans who did not experience MST. A substantial proportion of homeless Veterans using VHA services have experienced MST, and those who experienced MST had increased odds of mental health diagnoses. Homeless Veterans who had experienced MST had higher intensity of mental health care utilization and high rates of MST-related mental health care. This study highlights the importance of trauma-informed care among homeless Veterans and the success of VHA homeless

    Exposure to Agent Orange (AO) has been associated with the development of chronic lymphocytic leukemia (CLL). We performed a retrospective study of 2052 Vietnam veterans identified in the National VA Tumor Registry to assess the impact of AO exposure on CLL prognosis, treatment and survival. Prognostic factors did not differ based on exposure. Veterans exposed to AO were diagnosed younger (63.2 vs. 70.5 years, p < .0001) and had longer overall survival (median not reached vs. 91 months, p < .001). This prolonged survival was in the subgroups of patients aged 60-69 years (p< .0001) and those with 11q deletion (p < .0001). Those exposed to AO were more likely to be treated with fludarabine, chlorambucil and rituximab (38 vs. 21%, p < .001) and bendamustine plus rituximab (25 vs. 18%, p = 0.039) as first line therapy. Exposure to AO was not associated with either poor prognostic factors or shortened overall survival in our large veteran population with CLL.

    A clinical outcome tool is needed for the assessment of young athletes with low back pain. To translate and culturally adapt the Micheli functional scale (MFS), a self-report questionnaire developed to evaluate young athletes with low back pain (LBP) into Persian language and examine the reliability and validity of the Persian MFS (PMFS). A cross-sectional study was conducted to assess the psychometric properties of the PMFS. The PMFS was cross-culturally adapted into Persian language adopting forward/backward translation, expert panel review, and pre-testing. The PMFS was administered to young athletes with and without LBP. Main outcome measures were Persian MFS, Persian functional rating Index (PFRI), and visual analogue scale (VAS). A sample of 100 young athletes with LBP with a mean age of 16.5 ± 2.5 years participated. Fifty young athletes without LBP completed the PMFS. There was no missing responses and floor or ceiling effects. There was a significant difference for the total PMFS scores between young athletes with and without LBP. A significant correlation was found between the total PMFS score and the VAS (r = 0.92) or the PFRI (r = 0.82; P Persian MFS is valid and reliable for use in Persian-speaking young athletes with LBP.

    The development of communication systems has brought great social and economic benefits to society. As mobile phone use has become widespread, concerns have emerged regarding the potential adverse effects of radiofrequency electromagnetic radiation (RF-EMR) used by these devices. To verify potential effects of mobile phone radiation on the central nervous system (CNS) in an animal model. Male Wistar rats (60 days old) were exposed to RF-EMR from a Global System for Mobile (GSM) cell phone (1·8 GHz) for 3 days. At the end of the exposure, the following behavioral tests were performed: open field and object recognition. Our results showed that exposed animals did not present anxiety patterns or working memory impairment, but stress behavior actions were observed. Given the results of the present study, we speculate that RF-EMR does not promote CNS impairment, but suggest that it may lead to stressful behavioral patterns.

    Fear of falling may be related to falling during stroke onset. The Fall Efficacy ScaleInternational (FES-I) with excellent psychometric properties, is an instrument developed to assess patients' concerns about fallings. The aim of this study was to determine validation of this scale in Iranian patients with stroke. The "forward-backward" procedure was applied to translate the FES-I from English to Persian. One hundred-twenty patients who had suffered stroke, aged 40 to 80 years (55% male) completed the Persian FES-I, Geriatric Depression Scale-15 (GDS-15), General Health Questionnaire-28 (GHQ-28), Berg Balance Scale (BBS) and Timed up and Go (TUG) questionnaires. The interval time for the test-retest of the Persian scale was 7-14 days. The test-retest and inter-rater reliabilities of the Persian FES-I were excellent (ICC2,1=0.98, pPersian scale showed only one significant factor. The total Persian FES-I score had a significantly negative correlation (pPersian FES-I proved to be an effective and valuable measurement tool to assess stroke patients' fear of falling in practice and research setting.

    This study examined the relative influences of PTSD, other psychopathology, and intimate partner alcohol and drug use on substance-related problems in U.S. veterans (242 couples, N = 484). Hierarchical regression analyses revealed that partner alcohol and drug use severity explained more variance in veteran alcohol use and drug use (20% and 13%, respectively) than did veteran PTSD, adult antisocial behavior, or depression symptoms combined (6% for veteran alcohol use; 7% for veteran drug use). Findings shed new light on the influence of relationship factors on veteran alcohol and drug use and underscore the importance of couples-oriented approaches to treating veterans with comorbid PTSD and substance abuse.

    Sporulated oocysts of Eimeria nieschulzi Dieben 1924, a rat coccidium, were exposed to radiation, heat, or both in an effort to attenuate the parasite. Moderate levels of each treatment or combination thereof attenuated the parasite, reduced pathogenesis (as judged by oocyst discharge during primary infection), and produced immunity to challenge when the oocysts were subsequently inoculated into rats. Thus, heat- and/or radiation-treated E. nieschulzi oocysts fed to rats could reduce pathogenesis during a primary infection and yet give good homologous protection

    In spite of accumulating information about pathological aspects of sulfur mustard (SM), the precise mechanism responsible for its effects is not well understood. Circulating microRNAs (miRNAs) are promising biomarkers for disease diagnosis and prognosis. Accurate normalization using appropriate reference genes, is a critical step in miRNA expression studies. In this study, we aimed to identify appropriate reference gene for microRNA quantification in serum samples of SM victims. In this case and control experimental study, using quantitative real-time polymerase chain reaction (qRT-PCR), we evaluated the suitability of a panel of small RNAs including SNORD38B, SNORD49A, U6, 5S rRNA, miR-423-3p, miR-191, miR-16 and miR-103 in sera of 28 SM-exposed veterans of Iran-Iraq war (1980-1988) and 15 matched control volunteers. Different statistical algorithms including geNorm, Normfinder, best-keeper and comparative delta-quantification cycle (Cq) method were employed to find the least variable reference gene. miR-423-3p was identified as the most stably expressed reference gene, and miR- 103 and miR-16 ranked after that. We demonstrate that non-miRNA reference genes have the least stabil- ity in serum samples and that some house-keeping miRNAs may be used as more reliable reference genes for miRNAs in serum. In addition, using the geometric mean of two reference genes could increase the reliability of the normalizers.

    Posttraumatic stress disorder (PTSD) is associated with executive functioning deficits, including disruptions in working memory (WM). Recent studies suggest that attention training reduces PTSD symptomatology, but the underlying neural mechanisms are unknown. We used high-density magnetoencephalography (MEG) to evaluate whether attention training modulates brain regions serving WM processing in PTSD. Fourteen veterans with PTSD completed a WM task during a 306-sensor MEG recording before and after 8 sessions of attention training treatment. A matched comparison sample of 12 combat-exposed veterans without PTSD completed the same WM task during a single MEG session. To identify the spatiotemporal dynamics, each group's data were transformed into the time-frequency domain, and significant oscillatory brain responses were imaged using a beamforming approach. All participants exhibited activity in left hemispheric language areas consistent with a verbal WM task. Additionally, veterans with PTSD and combat-exposed healthy controls each exhibited oscillatory responses in right hemispheric homologue regions (e.g., right Broca's area); however, these responses were in opposite directions. Group differences in oscillatory activity emerged in the theta band (4-8 Hz) during encoding and in the alpha band (9-12 Hz) during maintenance and were significant in right prefrontal and right supramarginal and inferior parietal regions. Importantly, following attention training, these significant group differences were reduced or eliminated. This study provides initial evidence that attention training improves aberrant neural activity in brain networks serving WM processing.

  17. Action spectra in mammalian cells exposed to ultraviolet radiation

    A review is given of the literature published since 1977 on action spectra in mammalian cells exposed to ultraviolet radiation in the wavelength region above 220 nm. Action spectra for lethal events are discussed for cell inactivation in normal cells, growth arrested cells and photosensitive cells. Action spectra for non-lethal events are also discussed in relation to pyrimidine dimer formation, photoreactivation and the use of photosensitisers. It was concluded from these studies that damage to the DNA, and the extent of the repair of this damage, seems to determine a cell's response to such parameters as inactivation, mutation, transformation, latent viral activation, cellular viral capacity and ultraviolet enhanced viral reactivation. In addition to the direct effects of UV on DNA, photosensitization of cellular responses with chemicals such as 8-MOP extend the wavelength range at which damage can be demonstrated. (U.K.)

    Persian leek is one of the most widely used herbal foods among Iranians. In this study, effects of oral administration of Persian leek on plasma and liver lipids were examined in hamster. Male Syrian hamsters were randomly divided into three groups: control (standard diet), high fat control (high-fat/high-cholesterol diet), Persian leek (high-fat/high-cholesterol diet + 1% per weight of diet from dried powdered Persian leek) for 14 weeks. High fat diet increased plasma and liver lipids as compared to standard diet. Adding Persian leek to the high-fat/high-cholesterol diet resulted in no significant changes in the concentration of the plasma lipids or liver cholesterol. However, liver triglycerides (TG), plasma Alanine aminotransferase and gene expression of tumor necrosis factor- α were decreased in hamsters fed high-fat diet containing Persian leek as compared to high-fat diet only. Persian leek might be considered as a herbal food that can reduce liver TG accumulation induced by high fat diets.

    The patients exposed to the atomic bomb radiation in Hiroshima area came to Beppu Spa to have hot spring therapy. During the fiscal year of 1982 (April, 1982, to March, 1983), 3972 persons came to the hot spring sanatorium, and 586 patients (14.8 %) received physical examination. Among them, 473 patients (80.7 %) were exposed to the atomic bomb radiation on August 6, 1945, or entered in the city of Hiroshima by August 20, 1945, according to the official notebook issued by the government. Physical examination was performed twice a week during their stay, and more than 53.5 % of the patients were older than 70, and the oldest was 93 years old. Blood pressure was measured when the patients came in and went out, and hypertensive patients were asked to observe the rule of treatment strictly. The complaints of the patients which brought them to the hot spring were mostly pain in bodies and lower extremities, and hypertension, common cold syndrome, diabetes and constipation. Patients took hot spring bath 2 - 3 times daily, and many patients had microwave and low frequency wave treatment. Soaking in a bath (containing 1.4 mg of cupric sulfate and 11.4 mg of zinc sulfate per liter) was practiced by diabetic patients. The therapeutic effects were difficult to judge because the period of stay of the most patients was about 10 days, but in most of them, subjective symptoms were relieved when they left the sanatorium.

  20. Do Persian Native Speakers Prosodically Mark Wh-in-situ Questions?

    2018-02-01

    It has been shown that prosody contributes to the contrast between declarativity and interrogativity, notably in interrogative utterances lacking lexico-syntactic features of interrogativity. Accordingly, it may be proposed that prosody plays a role in marking wh-in-situ questions in which the interrogativity feature (the wh-phrase) does not move to sentence-initial position, as, for example, in Persian. This paper examines whether prosody distinguishes Persian wh-in-situ questions from declaratives in the absence of the interrogativity feature in the sentence-initial position. To answer this question, a production experiment was designed in which wh-questions and declaratives were elicited from Persian native speakers. On the basis of the results of previous studies, we hypothesize that prosodic features mark wh-in-situ questions as opposed to declaratives at both the local (pre- and post-wh part) and global level (complete sentence). The results of the current study confirm our hypothesis that prosodic correlates mark the pre-wh part as well as the complete sentence in wh-in-situ questions. The results support theoretical concepts such as the frequency code, the universal dichotomous association between relaxation and declarativity on the one hand and tension and interrogativity on the other, the relation between prosody and pragmatics, and the relation between prosody and encoding and decoding of sentence type.

    To describe the normal ultrasonographic biometry of the Persian cat's eyes using B-mode ultrasonography. In a cross-sectional study, 20 healthy Persian cats with no history of previous ophthalmic disease were examined. Ocular biometry of the left and right eyes was measured using B-mode ultrasonography. Comparison of the average measurements between left and right eyes and between vertical and horizontal planes was performed using paired-sample t test. Correlation of ocular parameters with sex, age, head circumference and eye colour was evaluated. Mean ± standard deviation (SD) measurements of the ocular structures of anterior chamber, lens thickness, vitreous chamber and anterior to posterior dimension of the globe in 40 eyes were 4.1 ± 0.7, 7.7 ± 0.5, 8.2 ± 0.4 and 20.7 ± 1.0 mm, respectively. No significant difference was found between the ocular biometry of the left and right eyes or the horizontal and vertical planes. Of the ocular parameters, the following had a significant positive correlation with head circumference: axial globe length, anterior chamber and lens thickness. The vitreous body had a positive correlation with age. Regarding the breed predisposition of Persian cats to ocular problems, the present study provides baseline information for further clinical investigations of ocular abnormalities using B-mode ultrasonography. © 2014 Australian Veterinary Association.

    Radiation-use efficiency of growth (defined as biomass accumulation per unit of absorbed photosynthetically active radiation) of loblobby pine forest plots exposed to ambient or elevated atmospheric carbon dioxide concentration was compared. Biomass accumulation of the dominant loblobby pines was calculated from monthly measurements of tree growth and site-specific allometric measurements. Leaf area index was estimated by optical, allometric and interfall methods, depending on species. Results showed that depending on tree height, elevated carbon dioxide did not alter the above-ground biomass allocation in loblobby pine. Leaf area index estimates by the different methods were found to vary significantly, but elevated carbon dioxide had only a slight effect on leaf area index in the first three years of this study. The 27 per cent increase in radiation-use efficiency of growth in response to carbon dioxide enrichment is believed to have been caused primarily by the stimulation of biomass increment. It was concluded that long-term increases in atmospheric carbon dioxide concentration can increase the radiation-use efficiency of growth in closed canopy forests, but the magnitude and duration of this increase in uncertain. 57 refs., 2 tabs., 3 figs

    The purpose of this study was to analyze the incidence and structure of cogenital developmental defects in the grandchildren of subjects occupationally exposed to chronic external gamma-irradiation. For 830 children only grandfather was exposed, for 259 only grandmother, and for 468 grandfather and grandmother. The mean equivalent doses for gonads by the moment of conception of future parents of the cohort examined ranged from 17.3 to 145.3 sSv. The incidence and structure of congenital developmental defects in 1557 grandchildren of occupationally exposed subjects differed from that in controls. Multifactorial analysis failed to establish the effect of grandparents' and parents' exposure on the development of diseases in the progeny. Factors other than radiation proved to be significant. 13 refs.; 1 tab

    Dementia is a chronic neurodegenerative disease causing progressive and gradual impairment of different brain's cognitive functions. The prevalence of dementia is about 3 to 7% in different parts of the world. The aim of this study was to determine the etiologies of dementia according to the Traditional Persian Medicine scientists' viewpoint and introduce their recommended herbal remedies for this disease. The authors explored six main Traditional Persian Medicine textbooks for the disease of dementia, its etiologies and related recommended herbal treatments. Two main keywords of "Lisarghes" and" Nesyan" were searched for this purpose. Medical databases, including PubMed, Scopus, Google Scholar, and Science Direct were searched for related articles published between 1966 and 2016 to review the pharmacological components and active ingredients of suggested herbal medicines. According to the Traditional Persian Medicine, dementia is resulted from brain dystemperament, a condition caused by cold and moist or cold and dry tempers. To treat this disease, Traditional Persian scientists recommended various herbal remedies. Current studies have demonstrated that some of these medicinal plants have beneficial effects for the aforementioned disease, including acetyl cholinesterase inhibitory function, neuroprotective effects, and memory enhancing role. The Traditional Persian Medicine literature suggested different herbal remedies for treating dementia. Modern studies support the usefulness of some of these medicines. However, the effect of a large number of these remedies has remained unexamined, a matter which needs to be investigated in future researches.

    In recent years there has been a tremendous increase in use of Wi-Fi devices along with mobile phones, globally. Wi-Fi devices make use of 2.4GHz frequency. The present study evaluated the impact of 2.45GHz radiation exposure for 4h/day for 45days on behavioral and oxidative stress parameters in female Sprague Dawley rats. Behavioral tests of anxiety, learning and memory were started from day 38. Oxidative stress parameters were estimated in brain homogenates after sacrificing the rats on day 45. In morris water maze, elevated plus maze and light dark box test, the 2.45GHz radiation exposed rats elicited memory decline and anxiety behavior. Exposure decreased activities of super oxide dismutase, catalase and reduced glutathione levels whereas increased levels of brain lipid peroxidation was encountered in the radiation exposed rats, showing compromised anti-oxidant defense. Expression of caspase 3 gene in brain samples were quantified which unraveled notable increase in the apoptotic marker caspase 3 in 2.45GHz radiation exposed group as compared to sham exposed group. No significant changes were observed in histopathological examinations and brain levels of TNF-α. Analysis of dendritic arborization of neurons showcased reduction in number of dendritic branching and intersections which corresponds to alteration in dendritic structure of neurons, affecting neuronal signaling. The study clearly indicates that exposure of rats to microwave radiation of 2.45GHz leads to detrimental changes in brain leading to lowering of learning and memory and expression of anxiety behavior in rats along with fall in brain antioxidant enzyme systems.

A shift from light to heavy aggregates occurred in the polyribosomes of both intact and adrenalectomized rats after they were exposed to gamma rays. In irradiated adrenalectomized rats, however, the shift to heavier aggregates was not as great as that which occurred in irradiated adrenal-intact animals. Subcutaneous injection of cortisone acetate (10 mg/100 g body weight) also altered the liver polyribosome patterns of both intact and adrenalectomized rats within 8 hours of its administration. The shift which occurred following cortisone administration, however, was less striking than that seen after irradiation only. Thus, although adrenal glucocorticoids contribute to the radiation-indu ied shift in liver polyribosomes in adrenal-intact rats, other factors appear to be involved, since the shift is also obtained in adrenalectomized animals.

    Full Text Available Background and Aims: The dichotic listening subtest is an important component of the test battery for auditory processing assessment in both children and adults. A randomized dichotic digits test (RDDT was created to compensate for sensitivity weakness of double digits when detecting abnormal ear asymmetry during dichotic listening. The aim of this study was the development and  intial evaluation of the Persian randomized dichotic digits test.Method: Persian digits 1-10 (except for the bisyllabic digit, 4 uttered by a native Persian language speaker were recorded in a studio. After alignment of intensity and temporal characteristics of digit waveforms, lists 1 and 2 of the RDDT were reproduced. List 1 of the test was administered at 55 dBHL on 50 right-handed normal hearing individuals (with an equal sex ratio in the age group of 18-25 years and hearing thresholds of 15 dBHL or better in audiometric frequencies.Results: Mean (standard deviation of percent-correct score for right and left ears and right ear advantage of the subjects was 94.3 (5.3, 84.8 (7.7, and 9.5 (7.0 percent, respectively. Sixty percent of the subjects showed normal results and unilateral and bilateral deficits were seen in 24 percent and 16 percent, respectively, of studied individuals.Conclusion: It seems the Persian version of RDDT test is the same as the original test as it is able to test ear asymmerty, unilateral and bilateral deficits in dichotic listening.

    Combat deployment and reintegration are challenging for service members and their families. Although family involvement in mental health care is increasing in the U.S. Department of Veterans Affairs (VA) system, little is known about family members' preferences for services. This study elicited the perspectives of returning Afghanistan and Iraq war veterans with posttraumatic stress disorder and their families regarding family involvement in veterans' mental health care. Semistructured qualitative interviews were conducted with 47 veterans receiving care for posttraumatic stress disorder at the Central Arkansas Veterans Healthcare System or Oklahoma City VA Medical Center and 36 veteran-designated family members. Interviews addressed perceived needs related to veterans' readjustment to civilian life, interest in family involvement in joint veteran/family programs, and desired family program content. Interview data were analyzed using content analysis and constant comparison. Both groups strongly supported inclusion of family members in programs to facilitate veterans' postdeployment readjustment and reintegration into civilian life. Both desired program content focused on information, practical skills, support, and gaining perspective on the other's experience. Although family and veteran perspectives were similar, family members placed greater emphasis on parenting-related issues and the kinds of support they and their children needed during and after deployment. To our knowledge, this is the first published report on preferences regarding VA postdeployment reintegration support that incorporates the perspectives of returning male and female veterans and those of their families. Findings will help VA and community providers working with returning veterans tailor services to the needs and preferences of this important-to-engage population. (c) 2015 APA, all rights reserved).

    Traditional Persian Medicine (TPM) was the prevailing practice of medicine in the Eurasia region up through the 18th century, a practice of medicine stemming back to Hippocrates and to the 5000 year old civilization of the region. It is a school of medicine which touches on many a delicate points which may seem unimaginable within the realm of modern allopathic medicine. This practice of ancient medicine besides shedding light on various possible theoretical modern day disorders serves as a vast resource for therapeutics. In this paper, we present study of the manuscripts of this ancient medical practice in search of symptom presentations coinciding with presentation of multiple sclerosis (MS). This paper represents a comprehensive search through TPM texts and manuscripts with the intention to seek possible clues on MS from potentially valuable age-old resources. We predominantly focused our search on the works of five eminent physicians of Medieval Persia: Avicenna (980-1037 AD), Haly Abbas (949-982 AD), Rhazes (865-925 AD), Averroes (1126-1198 AD) and Jorjani (1042-1137 AD). In this paper, the authors attempt a theory and conclude with high probability that a conjunction of a series of signs, symptoms found in TPM texts under the terms khadar, isterkha and falej form the symptoms and the disease pattern of modern day MS. This theory draws upon existent similarities in terms of disease pathology, disease patterns and predisposing factors seen between MS and the related morbidities within Persian Medicine. We recommend further examinations of such potentially valuable long-standing resources, examining the diagnoses and treatments as set forth by Persian Medicine through international collaboration within the global scientific community.

  1. Reliability of semiconductor and gas-filled diodes for over-voltage protection exposed to ionizing radiation

    Directory of Open Access Journals (Sweden)

    Stanković Koviljka

    2009-01-01

    Full Text Available The wide-spread use of semiconductor and gas-filled diodes for non-linear over-voltage protection results in a variety of possible working conditions. It is therefore essential to have a thorough insight into their reliability in exploitation environments which imply exposure to ionizing radiation. The aim of this paper is to investigate the influence of irradiation on over-voltage diode characteristics by exposing the diodes to californium-252 combined neutron/gamma radiation field. The irradiation of semiconductor over-voltage diodes causes severe degradation of their protection characteristics. On the other hand, gas-filled over-voltage diodes exhibit a temporal improvement of performance. The results are presented with the accompanying theoretical interpretations of the observed changes in over-voltage diode behaviour, based on the interaction of radiation with materials constituting the diodes.

    This study examined the relative influences of posttraumatic stress disorder (PTSD), other psychopathology, and intimate partner alcohol and drug use on substance-related problems in U.S. veterans (242 couples, N = 484). Hierarchical regression analyses revealed that partner alcohol and drug use severity explained more variance in veteran alcohol use and drug use (20% and 13%, respectively) than did veteran PTSD, adult antisocial behavior, or depression symptoms combined (6% for veteran alcohol use; 7% for veteran drug use). Findings shed new light on the influence of relationship factors on veteran alcohol and drug use and underscore the importance of couples-oriented approaches to treating veterans with comorbid PTSD and substance abuse.

    In this study, we aimed to translate and test the validity and reliablity of the Persian version of the Manchester-Oxford Foot Questionnaire in foot and ankle patients. We translated the Manchester-Oxford Foot Questionnaire to Persian language according to the accepted guidelines, then assessed the psychometric properties including the validity and reliability on 308 patients with long-standing foot and ankle problems. To test the reliability, we calculated the intra-class correlation coefficient (ICC) for test-retest reliability and measured Cronbach's alpha to test the internal consistency. To test the construct validity of the Manchester-Oxford Foot Questionnaire we also administered the Short-Form 36 to patients. Construct validity was supported by significant correlation with SF36 subscales except for pain subscale of the persian MOXFQ with mental health of the SF36 (r=0.207). Intraclass correlation coefficient was 0.79 for the total MOXFQ and ranged from 0.83 to 0.89 for the three subscales. Cronbach's alpha for pain, walking/standing, and social interaction was 0.86, 0.88, and 0.89, respectively, and was 0.79 for the total MOXFQ showing good internal consistency in each domain. The Persian Manchester-Oxford Foot Questionnaire health scoring system is a valid and reliable patient-reported instrument for foot and ankle problems. Copyright © 2015. Published by Elsevier Ltd.

  4. Changes in viability of two Antarctic marine bacteria exposed to solar radiation in the water column: influence of vertical mixing

    2007-01-01

    The effect of UV radiation on two Antarctic marine bacterial strains (UVps and UVvi) was studied in the water column of Potter Cove (South Shetland, Antarctica). Quartz flasks were filled with the bacterial suspensions and exposed to solar radiation at 0 m, 1 m and 3 m depth. Assays using flasks exposed to direct solar radiation and others using flasks covered with/by interferential filters which discriminate between UVA and UVB, were performed. In other assays, a vertical mixing of 4 m/h was simulated. Both strains showed a significant decrease in viability (expressed as colony - forming units) when exposed to a surface UVB dose of 8.4 kJ m -2 . Studies with interferential filters showed a significant decrease at 0 and 1 m depth under both UV treatments. The UVps strain appeared to be more sensitive to UVB than to UVA. Damage produced by UVB was attenuated by the vertical mixing when the surface UVB dose was 4.8 kJ m -2 . This effect was not observed when surface UVB dose was 7.7 kJ m -2 . These results show that the negative effect caused by UVB radiation on the bacterio plankton would be significant only in the first meter of water column of the Antarctic coastal waters with high levels of suspended particulate material.

    Osteoarthritis of the knee is the most common chronic joint disease that involves middle aged and elderly persons. There are different clinical instruments to quantify the health status of patients with knee osteoarthritis and one example is the WOMAC score that has been translated and adapted into different languages. The purpose of this study was cultural adaptation, validation and reliability testing of the Persian version of the WOMAC index in Iranians with knee osteoarthritis. We translated the original WOMAC questionnaire into Persian by the forward and backward technique, and then its psychometric study was done on 169 native Persian speaking patients with knee degenerative joint disease. Mean age of patients was 53.9 years. The SF-36 and KOOS were used to assess construct validity. Reliability testing resulted in a Cronbach's alpha of 0.917, showing the internal consistency of the questionnaire to be a reliable tool. Inter-correlation matrix among different scales of the Persian WOMAC index yielded a highly significant correlation between all subscales including stiffness, pain, and physical function. In terms of validity, Pearson`s correlation coefficient was significant between three domains of the WOMAC with PF, RP, BP, GH, VT, and PCS dimensions of the SF-36 health survey (P<0.005) and KOOS (P<0.0001) . The Persian WOMAC index is a valid and reliable patient- reported clinical instrument for knee osteoarthritis.

    Full Text Available Menopause is not a disease; however the somatic and psychological symptoms that accompany it affect the life of women. Women health questionnaire (WHQ is a self-administered questionnaire that measures the physical and mental health of women ages 40 to 65 years. The purpose of this study is to provide psychometric documentation details of the translation of WHQ into the Persian language. A total of 350 peri and postmenopausal women were recruited from urban health centers in the city of Tabriz, between March and October 2015. The validity of WHQ was assessed using construct and discriminate validity. The reliability of questionnaire was assessed by test retest reliability and measuring internal consistency. The KMO was 0.791, and the Bartlett’s test of Sphericity was significant. Principle component analysis (PCA resulted in 9 factors which explained up to 55.4% of the total variance. Cronbach's coefficient was 0.799 and the Intraclass correlation coefficient (ICC of the Persian translation scale was 0.712. Evaluation of the psychometric properties showed that the Persian language translation of the 36-item version of the WHQ was appropriate when applied to middle aged women

    The Chernobyl Childhood Illness Program (CCIP) was a humanitarian assistance effort funded by the United States Congress. Its purpose was to assist the Ukrainian Government to identify and treat adolescents who developed mental and physical problems following their exposure as young children to Chernobyl radiation. Thirteen years after the Chernobyl nuclear plant accident in 1986, the CCIP examined 116,655 Ukrainian adolescents for thyroid diseases. Of these, 115,191 were also screened for depression, suicide ideation, and psychological problems. The adolescents lived in five of Ukraine's seven most Chernobyl radiation contaminated provinces. They were up to 6 years of age or in utero when exposed to nuclear fallout, or were born up to 45 months after Chernobyl. Ukrainian endocrinologist and ultrasonographers used physical examination and ultrasonography of the neck to evaluate the adolescents for thyroid tumors. The adolescents were then screened for depression by the Children's Depression Inventory (CDI). After this, Ukrainian psychologists conducted individual psychological interviews to corroborate the adolescents' CDI responses. Papillary thyroid carcinoma was diagnosed in eight adolescents, a high prevalence rate similar to that reported by other studies from the Soviet Union. Screening identified thyroid nodules in 1,967 adolescents (1.7%). Depression was diagnosed in 15,399 adolescents (13.2%), suicide ideation in 813 (5.3%), and attempted suicide in 354 (2.3%). Underlying components of the participants' depression were negative mood, interpersonal difficulties, negative self-esteem, ineffectiveness, and anhedonia. Depression was greater in females (77%). Those with thyroid and psychological problems were referred for treatment. The adolescents screened by CCIP represent the largest Ukrainian cohort exposed to Chernobyl radiation as children who were evaluated for both thyroid tumors and depression. The group had an increased prevalence of thyroid cancer

    2012-01-01

    The International Commission on Radiological Protection (ICRP) emphasized the need to protect non-human biota from the potential effects of ionizing radiation and proposed to include molecular effects such as DNA damage as endpoints. Molecular effects of ionizing radiation exposure in representative non-humans are largely unexplored and sufficient data is not available in fishes. Gene expression is a fast and sensitive end point in detecting the molecular cues as a result of ionizing radiation exposure in a wide variety of aquatic organisms under suspected environmental contamination. Exposure to ionizing radiation transiently alters gene expression profiles as cells regulate certain genes to protect cellular structures and repair damage. The present study focused on genes like Gadd45á, Cdk1 and Bcl-2 in DNA damage repair and cell cycle machinery and its implication as molecular markers of radiation exposure. This study is first of its kind showing the in vivo expression profile of cell cycle genes in fish exposed to gamma radiation. Although this preliminary investigation points to certain molecular markers of ionizing radiation, elaborate studies with various doses and dose-rates are required before these markers find application as prospective molecular markers in aquatic radiation biodosimetry

    The report examines existing systems for providing care and benefits to persons who may have been injured by radiation exposure and recommends additional guidelines for handling radiation-related claims. The benefits systems examined are Veterans' benefits, Federal Employees Compensation Act, Longshoremen's and Harbor Workers' Compensation Act, State Workers' Compensation programs, Government and private 'back-up' program, Social Security Disability Insurance (Medicare), Supplemental Security Income (Medicaid), private health insurance, government hospitals, and remedies available under the judicial system. The report recommends that the Federal Government develop guidelines to determine the likelihood of a causal relationship between a person's illness and his exposure to radiation; that Federal compensation programs and State programs develop criteria for deciding radiation exposure claims, based on those guidelines; that a national registry of radiation workers be established to maintain individual radiation exposure records; and that the Federal Government annually compile compensation claims based on radiation exposure. Appendixes list those groups of people most likely to be exposed to radiation, and the benefits available under the various compensation programs listed above

    2015-09-01

    Entomopathogenic nematodes (EPNs) can be highly effective biocontrol agents, but their efficacy can be reduced due to exposure to environmental stress such as from ultraviolet (UV) radiation. Our objectives were to 1) compare UV tolerance among a broad array of EPN species, and 2) investigate the relationship between reduced nematode viability (after exposure to UV) and virulence. Nematodes exposed to a UV radiation (254 nm) for 10 or 20 min were assessed separately for viability (survival) and virulence to Galleria mellonella. We compared 9 different EPN species and 15 strains: Heterorhabditis bacteriophora (Baine, fl11, Oswego, and Vs strains), H. floridensis (332), H. georgiana (Kesha), H. indica (HOM1), H. megidis (UK211), Steinernema carpocapsae (All, Cxrd, DD136, and Sal strains), S. feltiae (SN), S. rarum (17C&E), and S. riobrave (355). In viability assessments, steinernematids, particularly strains of S. carpocapsae, generally exhibited superior UV tolerance compared with the heterorhabditids. However, some heterorhabditids tended to be more tolerant than others, e.g., H. megidis and H. bacteriophora (Baine) were most susceptible and H. bacteriophora (Vs) was the only heterorhabditid that did not exhibit a significant effect after 10 min of exposure. All heterorhabditids experienced reduced viability after 20 min exposure though several S. carpocapsae strains did not. In total, after 10 or 20 min exposure, the viability of seven nematode strains did not differ from their non-UV exposed controls. In virulence assays, steinernematids (particularly S. carpocapsae strains) also tended to exhibit higher UV tolerance. However, in contrast to the viability measurements, all nematodes experienced a reduction in virulence relative to their controls. Correlation analysis revealed that viability among nematode strains is not necessarily related to virulence. In conclusion, our results indicate that the impact of UV varies substantially among EPNs, and viability alone

    Full Text Available In the Islamic period, Apollonius of Tyana (c. 15-100 CE was well known both as “Lord of the Talismans” (ṣāḥib al-ṭilasmāt and as a Neo-Pythagorean-Hermetic philosopher. In his Kitāb al-Aḥjār, Jābir b. Ḥayyān cites “the Muslim advocates of Apollonius” (aṣḥāb Balīnās al-Islāmīyūn. The reference shows that Apollonius’ most prominent work, Sirr alkhalīqa, was already famous in the Arabicspeaking world from very early on. This article gives an overview of citations of Apollonius in Islamic sources from different fields and of the works generally attributed to him. Furthermore, I review Sirr al-khalīqa, its influences on the Jābirian works and its reception in the Ismā‘īlī tradition. This article additionally discusses an Arabic commentary of Sirr al-khalīqa by ‘Awn b. al-Mundhir (4th/10th century, which is extant in a unique manuscript, and its hitherto unknown Persian translation. This Persian translation covers parts of Ibn al-Mundhir’s work not available in the Arabic excerpt and is therefore an important source for the history of Islamic alchemy. An edition of the Persian translation is given as an appendix.

    Full Text Available Due to the important role of figures of speech in prose, the present research tried to investigate the figures of speech in the novel, Harry Potter Series, and their Persian translations. The main goal of this research was to investigate the translators’ problems in translating figures of speech from English into Persian. To achieve this goal, the collected data were analyzed and compared with their Persian equivalents. Then, the theories of Newmark (1988 & 2001, Larson (1998, and Nolan (2005 were used in order to find the applied strategies for rendering the figures of speech by the translators. After identifying the applied translation strategies, the descriptive and inferential analyses were applied to answer the research question and test its related hypothesis. The results confirmed that the most common pitfalls in translating figures of speech from English into Persian based on Nolan (2005 were, not identifying of figures of speech, their related meanings and translating them literally. Overall, the research findings rejected the null hypothesis. The findings of present research can be useful for translators, especially beginners. They can be aware of the existing problems in translating figures of speech, so they can avoid committing the same mistakes in their works.

    Full Text Available Background: Research in marine pharmacology will promise new bioactive agents. The marine bioenvironment is the unique resource for bioactive agents that could not be found in terrestrial organisms. Methods: A total of known 611 seashells species in the Persian Gulf were investigated for synonymy in OBIS database. Then, all the species, including their synonymy were searched in PubMed database to find their isolated bioactive agents. Results: From 611 known seashells in the Persian Gulf, 172 genera/species had bioactive compounds. Bioactive agents were isolated and purified for 16 genera/ species. The crude or purified extracts from these seashells had immunomodulatory effects (6 seashells, anti-toxicologic effects (4 seashells, analgesic (1 seashell, cardiotonic and vasoactive agents (2 seashells, hypolipidemic agents (4 seashells, anti-osteoporotic and osteoblastic agents (2 seashells and anti-dermatitis effect (1 seashell. Conclusion: The known seashells from the Persian Gulf have bioactive and immunomodulatory compounds and increase in the efforts to isolate these agents will promise a treasure for novel anti-infective agents.

    Microplastics (MPs; distribution, and polymer types in littoral surface sediments of the Persian Gulf were performed. A two-step method, with precautions taken to avoid possible airborne contamination, was applied to extract MPs from sediments collected at five sites during low tide. MPs were found in 80% of the samples. Across all sites, fiber particles were the most dominate shape (88%), followed by films (11.2%) and fragments (0.8%). There were significant differences in MP particle concentration between sampling sites (p value polymer types. More than half of the observed MPs (56%) were in the size category of 1-4.7 mm length, with the remaining particles (44%) being in the size range of 10 μm to <1 mm. Compared to literature data from other regions, intertidal sediments in the Persian Gulf cannot be characterized as a hot spot for MP pollution. The present study could, however, provide useful background information for further investigations and management policies to understand the sources, transport, and potential effects on marine life in the Persian Gulf.

    Israeli investigators have identified several relatively frequent disorders due to founder point mutations in Persian (Iranian) Jews, who, for nearly three centuries up to the Islamic Revolution of 1979, were completely isolated reproductively. Using a community-based model previously employed with Tay-Sachs disease prevention, we developed a pilot program for the Persian Jewish community of greater Los Angeles. We screened for mutations responsible for four relatively frequent autosomal recessive conditions in Persian Jews in which effective interventions are available for each: Pseudocholinesterase deficiency (butyryl cholinesterase deficiency); Congenital hypoaldosteronism (corticosterone methyl oxidase II); Autoimmune polyendocrinopathy (autoimmune regulatory element); and Hereditary Inclusion Body myopathy. One thousand individuals volunteered. Mutations were assessed in saliva-derived DNA and were positive for 121/1000 butyryl cholinesterase deficiency; 92/1000 Hereditary Inclusion Body myopathy; 38/1000 corticosterone methyl oxidase II; and 37/1000 autoimmune regulatory element. Ten homozygous individuals (9 butyryl cholinesterase deficiency and 1 Hereditary Inclusion Body myopathy) and 10 "at-risk" couples (seven for butyryl cholinesterase deficiency and one each for the other three disorders) were identified. These frequencies are comparable with those in Israel and indicate an extraordinary level of inbreeding, as anticipated. A carefully planned effort can be delivered to an "increased risk" community if detailed attention is given to planning and organization. However, availability of an effective intervention for those found to be "at-risk" or possibly affected, is essential before embarking.

    This report updates, for 1980 through 1982, the results of continuing medical surveillance of a Marshallese population accidentally exposed to radioactive fallout in March 1954. The originally exposed Marshallese population comprised 64 persons on Rongelap Atoll who each received, on the average, an estimated 190 rads of absorbed external gamma radiation, 18 on Ailingnae Atoll who received 110 rads, and 159 on Utirik who received 11 rads. There were, in addition, 3 persons in utero on Rongelap, 1 person in utero on Ailingnae, and 8 persons in utero on Utirik who are considered exposed. The recipients of primary medical care include exposed and comparison populations as well as a rather large number of additional beneficiaries who are seen on a humanitarian basis of practical need and resource availability. In recent years, about 1400 people have been seen annually. This report, however, deals with four clearly defined groups: the remaining individuals who were exposed to radioactive fallout on Rongelap, Ailingnae, and Utirik in 1954 (including those in utero), and a comparison population of individuals from Rongelap who were unexposed. The number of persons now in each exposure category are 51, 12, 116, and 137, respectively. 100 references, 4 figures, 5 tables

    Evaluation of haematological indicators is carried out as routing in medical surveillance of workers exposed to ionizing radiation, in order to assest the initial and continuing fitness for their intended tasks. The purpose of this work is to analize the behaviour of haematological parametsrs in relation with the time of exposure as well as received doses for workers. It was stabilished a 8 years follw up for the 74 workers of the radiotherapy service in the Oncological Hospital in Havana City. As result were observed no significant changes on mean number of leucocytes, platelets an haemoglobin, which oscillate within normal limits stablished for adult people. Allthought it was incountered an increase in the number of cases with leucopenia, in direct relation with the increase of time of exposure an cumulative doses. The incidence of those cases was 2,3 times higher in the 8th year of the follow up, in relation with the begining of the exposition to ionizing radiation

  7. Radiocarbon age and diagenesis of oolitic sediments from the Persian Gulf

    Radiocarbon measurements of different parts of ooids of Pleistocene and Holocene oolitic sediments from the Persian Gulf on the coast of Kuwait indicated that atmospheric carbon dioxide had been involved in the recrystallization of aragonite and in the diagenesis of the oolitic sediments. The radiocarbon activity of different layers of sediments generally corresponds to their stratigraphic sequence. The radiocarbon ages of several earlier layers, however, seem to be reduced due to recrystallization and diagenesis. The radiocarbon ages of well-preserved shells of mollusks of the fossiliferous horizon are lower than their alleged Pleistocene geological age. The rate of emergence of the shore between one and several mm.yr -1 was established which corresponds to that recorded in the mouth of the Persian Gulf and in Qatar. (author)

    Full Text Available Background: The larval stages of Gasterophilus are obligate parasites in the gastrointestinal tract of equine account­able for pathologic ulcers in the Persian onager gastrointestinal. The aim of the current report was to study the histo­pathological change with G. pecorum larvae in the esophagus of a Persian onager.Methods: This study was performed in Iranian Zebra propagation and breeding site in Khartouran National Park, southeast of Shahrud City, Semnan Province, Iran in 2014. Following a necropsy with specific refer to esophagus of one adult female Persian onager were transmitted to the laboratory. After autopsy, parasites collected from the esophagus were transmitted into 70% alcohol. For histopathological investigation, tissue samples were collected from the esophagus. The tissues were fixed in 10% buffered formalin, and conformity routine processing, there were stained with Hematoxylin and eosin.Results: After clarity by lactophenol parasites were identified as G. pecorum. Microscopic recognition contained hyperemia, inflammatory cell infiltration, epithelial destruction, esophageal gland hyperplasia.Conclusion: This is the first survey of G. pecorum and histopathological study in the Persian onager esophagus in the world.

  9. The Effect of Culture Type on the Length of Persian Proverbs Compared to their English Equivalents

    Full Text Available The interrelation of culture and language is to the extent that many classifications of culture are based on linguistic factors. In this article, high and low context cultures division is assessed on English and Persian as they belong to different cultural types. Forty Persian proverbs are contrasted with their equivalents in English to investigate whether there is a difference in the number of word forms used in each. In order to avoid linguistic differences which are effective in enumerating word forms, the second lines in linguistic glosses provided for Persian proverbs including a one to one correspondence of each word in English are used to count word forms. Results show that 70 percent of the Persian proverbs in the data are longer than their English counterparts. This shows that relative length of proverbs can be a distinguishing factor reflecting cultural types. The results not only confirm the applicability of this cultural division in the field of proverbs, but also a matter of tendency rather than a dichotomy in belonging to a high or low context culture is proposed. At the end, there are suggestions for further relevant investigations.

    OBJECTIVE: To examine the assumption that postdeployment incidence of sickness and other absence from work are higher among Gulf War Veterans compared with nonveterans. METHODS: A prospective registry study including a cohort of 721 Danish Gulf War Veterans and a control cohort of 3,629 nonveterans...... and nonveterans in the incidence rate of long-term sickness absence. After an initial short period (3 months) with elevated incidence rate of long-term absence from work among veterans, there was no difference between the cohorts. CONCLUSION: Among Danish Gulf War Veterans, no postdeployment increased risk...... outcomes and information on deployment history was studied using time-to-event analysis. The index date was the return date from the last deployment to the Gulf. The follow-up period was the time from index date until April 27, 2014. RESULTS: As the main finding, no difference was found between veterans...

  13. Review of NCRP radiation dose limit for embryo and fetus in occupationally-exposed women

    International Nuclear Information System (INIS)

    Anon.

    1977-01-01

    On the basis of the current review, the NCRP has decided to make no change in the current recommendation of its radiation dose limit to the unborn. The NCRP recommendation is restated here as follows: During the entire gestation period, the maximum permissible dose equivalent to the embryo-fetus from occupational exposure of the expectant mother should be 0.5 rem. Since the preparation of the 1971 report there has been no new evidence concerning teratogenic or carcinogenic effects of irradiation of the embryo-fetus that would justify a change in the limit in either direction. It is implicit in this position and recommendation that women who can reasonably be expected to be pregnant should not, in certain instances, be exposed to the same radiation environment as women who are not considered fertile or as men. This applies particularly to conditions where radiation workers can receive dose equivalents of 0.5 rem or more in short periods

    1992-01-01

    Research works of epidemiology and experimental biology concerning health effects on populations exposed to low level ionizing radiation in China have been reviewed, with emphasis on the studies of mortality of malignancies and prevalence of hereditary diseases in a high background radiation area (HBRA) (radiation level is about three times of the control area of normal background CA), where the inhabitant families have lived for many generations. About one million person-years in HBRA and as many in CA were observed for cancer mortality. Statistical analysis showed that no difference was found either in mortality of all cancers or leukemias between HBRA and CA. The incidence of Down Syndrome in HBRA was within the range of spontaneous incidence and dependent on age of maternity. The characteristics of adaptive response induced by low level irradiation in humans as well as in experimental animal lymphocytes observed in Chinese laboratories are also discussed in this presentation

    Two mouse strains (RF/J and C57B1/6J) were exposed to x-ray doses totaling 400, 800, and 1200 rad. Total doses were given in 200-rad fractions at 7-day intervals to the whole body, gut only, or bone tissue with the gut shielded. Animals were anesthetized during exposure. Two control groups were used. A sham control group was anesthetized but not exposed to x rays, and another control group received neither anesthesia nor x-radiation. All mice were retained in a standard laboratory environment for observations on life span and histopathology at death. Life shortening was observed in all irradiated groups of strain RF/J mice and was attributed primarily to an increase in incidence and/or earlier onset of neoplasia. Life shortening was observed in the C57B1/6J whole-body exposed mice, but the effect appeared to be noncarcinogenic. Shielding of the bone or gut tissue proved to have a 100% sparing effect in strain C57 mice and none in strain RF mice. In both mouse strains, the sham control groups (anesthetized but not irradiated) showed approximately 8% life shortening below the non-anesthetized control groups and increased incidences of neoplasia of approximately 40%, suggesting that sodium pentabarbital may be as carcinogenic as x-radiation

  17. Some Problems of American Students in Mastering Persian Phonology.

    An adult learning to speak a foreign language normally retains an "accent" which may affect the intelligibility of certain sounds, but more often simply conveys the fact that the speaker is a non-native speaker. Various scholars have experimented and discussed the elements involved in a foreign accent. However, in Iran very few researchers have attempted to verify scientifically what are the phonetic and phonological aspects of an "accent." This author tried to determine whether or not a selected group of words, emphasizing stop voicing, produced by native speakers of Persian had significant phonetic and phonemic differences from those achieved by the American students. Subjects for the experiments were three groups of students, one Iranian, two American. A contrastive analysis of the Persian and the English stop consonants was made. An identical measurement test for all three groups was administered. Utilized was a Kay Sona-graph for acoustic analysis, and all spoken data from the Iranian group were compared with those of the American groups. An examination of acoustic correlates of Tehran stops produced by American students shows that the phonetically different but similar feature of /voice/ found in Tehran, Persian and English stops is intuitive to the Americans, and that the language learner cannot readily disassociate a phonological feature from habits of articulation. The results of this research support using the phonetic method for adult learners who want to improve their pronunciation ability. Further research and experimentation is necessary on the effect of the suprasegmental elements on a foreign accent and the most effective teaching materials and methods and to explore other possible techniques in the teaching process.

    Reliability and validity are the key concepts in measurement processes. Young internet addiction test (YIAT) is regarded as a valid and reliable questionnaire in English speaking countries for diagnosis of Internet-related behavior disorders. This study aimed at validating the Persian version of YIAT in the Iranian society. A pilot and a cross-sectional study were conducted on 28 and 254 students of Qom University of Medical Sciences, respectively, in order to validate the Persian version of YIAT. Forward and backward translations were conducted to develop a Persian version of the scale. Reliability was measured by test-retest, Cronbach's alpha and interclass correlation coefficient (ICC). Face, content and construct validity were approved by the importance score index, content validity ratio (CVR), content validity index (CVI), correlation matrix and factor analysis. The SPSS software was used for data analysis. The Cronbach's alpha was 0.917 (CI 95%; 0.901 - 0.931). The average of scale-level CVI was calculated to be 0.74; the CVI index for each item was higher than 0.83 and the average of CVI index was equal to 0.89. Factor analysis extracted three factors including personal activities disorder (PAD), emotional and mood disorder (EMD) and social activities disorder (SAD), with more than 55.8% of total variances. The ICC for different factors of Persian version of Young Questionnaire including PAD, EMD and for SAD was r = 0.884; CI 95%; 0.861 - 0.904, r = 0.766; CI 95%; 0.718 - 0.808 and r = 0.745; CI 95%; 0.686 - 0.795, respectively. Our study showed that the Persian version of YIAT is good and usable on Iranian people. The reliability of the instrument was very good. Moreover, the validity of the Persian translated version of the scale was sufficient. In addition, the reliability and validity of the three extracted factors of YIAT were evaluated and were acceptable.

    Life evolved in an environment filled with a wide variety of ionizing and non-ionizing radiation. It was previously reported that medical exposures to pregnant women increases the risk of low birth weight. This study intends to investigate the relationship between exposure to ionizing and non-ionizing radiation and the risk of low birth weight. One thousand two hundred mothers with their first-term labor (vaginal or cesarean) whose newborns' history had been registered in neonates' screening program in Shiraz were interviewed and surveyed. Data collection was performed by the assessment of mother's history of radiography before and during pregnancy, physical examination of the mother for height and weight and weighing and examining the newborn for any diagnosis of disease and anomalies. There were no statistical significant differences between the mean weight of newborns whose mothers had been exposed to some common sources of ionizing and non-ionizing radiations such as dental or non dental radiographies, mobile phone, cordless phone and cathode ray tube (CRT) and those of non-exposed mothers. The findings of this study cast doubt on previous reports, which indicated that exposure to ionizing radiation during pregnancy increased the risk of low birth weight.
