Excitatory and inhibitory effects of nitric oxide on weight, size, and histological changes of rat cerebellum
Karambaksh A,Noori Mougahi SMH,Hassan Zadeh GR,Tak Zaree N
Tehran University Medical Journal , 2013,
Abstract: Background: Nitric oxide (NO) is produced in different body organs in mammals and numerous physiological and pathological properties are attributed to this small molecule. The precursor of this substance in the body, L-arginine, is synthesized by the enzyme nitric oxide synthase (NOS), and it is catalyzed, and is inhibited by a substance called L-NG-nitroarginine methyl ester (L-NAME). In this study we investigated the qualitative and quantitative effects of nitric oxide on cerebellar histopathology in vivo environment via increasing and decreasing its production.Methods: Forty Wister rats, weighing 200- 250 gr with a mean age of 8 weeks, were divided into 5 groups after making sure the rats were pregnant. Except the control group, the other pregnant groups, respectively received: 2 ml/kg normal saline, 200 mg/kg L-arginine, 20 mg/kg L-NAME and a mixture of the same doses of L-arginine and L-NAME on the third, fourth and fifth days of pregnancy. On day 18 of pregnancy, we anesthetized the rats, excised the cerebellum after craniotomy and fixed the organs in 10% formalin. We later prepared 5 to 6-micron in thickness tissue sections and dyed them by the routine Hematoxylin and eosin (HE) and Masson's Trichrom staining methods before studying them by light microscopy.Results: There was a significant difference between the rats receiving L-arginine and the rats in other groups (P<0.01). Conclusion: This study showed that L-NAME is capable of significantly decreasing the injury caused by nitric oxides in rat cerebellum.
Share of Nations in 37 International Public Health Journals: An Equity and Diversity Perspective Towards Health Research Capacity Building
N Keshavarz Mohammadi,F Zaree,E de Leeuw,MM Emamjomeh
Iranian Journal of Public Health , 2011,
Abstract: Background: This paper contributes to further exploration of inequity in access to health research capacity development by examining the representation of different nations in international public health journals. It also aims to examine the degree of diversity that exists in these journals.Methods: This study is a descriptive survey. It was done with objective sampling on 37 ISI health journals on October of 2008.The number and nationality of people in different editorial positions of the journals was identified. The second analy-sis involved recalculating the numbers obtained for each nation to the population size of nations per million inhabitants. In order to better compare countries in terms of presence in editorial team of the journals, a ‘public health editor equity gap ratio' (PHEEGR) was developed.Results: Low income countries have occupied none of the leadership positions of chief editor or associate /assistant chief editors and middle income countries at maximum shared less than 5 percent. The PHEEGR gap in access to the different editorial positions between highest to the lowest representation of countries was 16/1 for chief editors, 12/1 for associate editors , 335/1 for editorial boards and 202/1 for associate editorial boards. However, after normalizing the data to the country's population, the gap increased significantly.Conclusion: There is an imbalance and possibly even inequity in the composition of editorial boards and offices of interna-tional health journals that should be paid significant attention. This can contribute to fill the equity gap exists between health in developing and developed countries.
Study of sexual behavior in male soldiers for STD/HIV prevention opportunities

Indian Journal of Dermatology, Venereology and Leprology , 2004,
Abstract: BACKGROUND: A survey was undertaken in patients of sexually transmitted infections with the aim of exploring STD and HIV prevention opportunities. METHODS: A behavioral survey was conducted on 56 soldiers while being treated or followed up for a sexually transmitted disease. They were studied for their attitude and sexual activity patterns relevant to the transmission of STDs. In addition, the individual′s outlook to sexual life and motivation factors was assessed. RESULTS: The study revealed that the source of infection of STD was equally divided between commercial sex worker (CSW) and casual sexual relationships. The majority did not use barrier contraceptives and knowledge about their protective role was insufficient. Access to health education was satisfactory; however, awareness levels for preventive action were still inadequate. Homosexuality was rare and most soldiers could stay without frequent sex. Alcohol was not found to be a significant co-factor. CONCLUSIONS: Heterosexual contact remains the main route of sexual contact. A wide variation in casual relationships and motivating factors was noted. Long abstinence and transit periods, traditionally considered major reasons for a soldier′s indulgence in sex did not seem to play a major role. The role of sex parlors in the army was negated.
Needlestick Injuries in Dentistry
N Gupta,J Tak
Kathmandu University Medical Journal , 2011, DOI: 10.3126/kumj.v9i3.6307
Abstract: Needlestick injuries and other sharps-related injuries which expose health care professionals to bloodborne pathogens continue to be an important public health concern. Dentists are at increased risk of exposure to bloodborne pathogens, including Hepatitis B, Hepatitis C, and HIV. This article presents comprehensive information on Needlestick injuries (NSI), post exposure prophylaxis, precautions and suggestions for prevention of NSI in dentistry. Dentists should remember and apply many precautions to prevent the broad spectrum of sharps and splash injuries that could occur during the delivery of dental care.

Data-dependent Posterior Propriety of Bayesian Beta-Binomial-Logit Model
Hyungsuk Tak,Carl N. Morris
Mathematics , 2015,
Abstract: A Beta-Binomial-Logit model is a Beta-Binomial model with covariate information incorporated via a logistic regression. Posterior propriety of a Bayesian Beta-Binomial-Logit model can be data-dependent for improper hyper-prior distributions. Various researchers in the literature have unknowingly used improper posterior distributions or have given incorrect statements about posterior propriety because checking posterior propriety can be challenging due to the complicated functional form of a Beta-Binomial-Logit model. We derive data-dependent necessary and sufficient conditions for posterior propriety within a class of hyper-prior distributions that encompass those used in previous studies.
Risk Assessment and Examination of Economic Aspects of Precision Weed Management
Katalin Takács-Gy?rgy,István Takács
Sustainability , 2011, DOI: 10.3390/su3081114
Abstract: The aim of this research is to investigate plant production sustainability, the economical requirements, risks, and identify threshold levels to switching on, or off precision weed management techniques in Hungarian growing and sales conditions; taking into consideration that the implementation of precision technology can be justified also by its role in the reduction of environmental load, which would create a harmony between individual usefulness and social utility. A simulation model has been developed to investigate the return of extra investments, along with the risk of this return in relation to the soil type, weed coverage, and the sales price.
Effects of Low Power He-Ne Laser Radiation on Injured Sciatic Nerve
N Tak Zareh,M Jamaly,D Yarmohammadi
Tehran University Medical Journal , 2001,
Abstract: The nervous system has an important and vital role in the human body, but unfortunately the repairment of damaged nervous tissue is very slowly. For a long time, the scientists have been involved in finding ways to speed up this process. Radiation of low power He-Ne laser has been suggested to as a way to improve this issue. In this study, 20 rats were divided randomly into control and case groups. The sciatic nerves of all these rats were damaged under general anesthesia and sterile conditions. The day of surgery was considered as the day zero. Rats of case group received every day laser radiation (?=65 mm). At 27th day rats were killed by ether and the sciatic nerve was studied histologically. Data was analysed and the difference was significant. In the case group the repairment was faster. We concluded that low power He-Ne laser radiation on crushed sciatic nerve of the rats has accelerated the nerve repairment process.
Engineering Evaluation about the Role of Innovation in a Globalized Economy
Zoltán Koczor,áron Takács
Acta Polytechnica Hungarica , 2008,
Abstract: New trends in production processes result in the important role of innovation in aglobalized economy. In the different market segments, strong competition does not alloweven the smallest loss of the traditional processes, so the whole value-add process has to bemanaged by a complex, globalized, IT-based system and standardized managementmethods. In order to provide adequate and effective solutions the critical process elements,a whole new set of innovative engineering methods has to be developed. This paperanalyses the means related to the existing production systems of light industry, discussingin detail the LEAN logic that is to minimise stock levels; and on the other hand attempts togive an overview of the up-to-date methods in proportion to their actual role.

Acta Medica Okayama , 2000,
Abstract: The majority of the t(14;18) chromosome translocations that occur in non-Hodgkin centroblastic-centrocytic follicular lymphoma can be detected by various methods. During the translocation process the bcl-2 gene located on chromosome 18 (18q21) is translocated to the JH region of the immunoglobulin gene of chromosome 14 (14q32). The most frequent type of bcl-2 translocations is the mbr type, whereas the immunoglobulin gene breaks mainly at the JH1-6 exons. About one of the 10(5) cells bearing the translocation can already be detected by using nested polymerase chain reaction (PCR). Eight patients suffering from follicular lymphoma were included in this study, which considered the usefulness of the PCR method. The results are in good agreement with those obtained by conventional diagnostic methods. Translocation can be detected, however, in patients with non-malignant diseases such as Sj gren's syndrome (about 5% of the patients) and in a patient with Whipple disease. In addition, translocation was detected in lymphocytes of peripheral blood of a healthy donor. Since lymphomas are detected in patients with Sj gren's syndrome with a relative high frequency, an early diagnosis of the translocation could improve the treatment of the disease. Nevertheless, a diagnosis of lymphoma is valid only in cases of bone marrow translocation-positivity.
