Iranica Journal of Energy and Environment (IJEE) , 2012,
Abstract: Polycyclic aromatic hydrocarbons (PAHs) concentrations in sediments measured from five stations in coastal area of Bushehr-Iran. Total PAHs concentration ranged from 844.9 to 4790.3 ng g-1 in summer and 935.0 to 4972.0 ng g-1 in winter. Significant difference was observed between total PAHs concentration in studied stations (P<0.05). Among the studied stations tPAHs concentration was higher in Rafael and followed by Sheghab station. The lowest level of tPAHs observed in Abshirinkon station. There was no significant difference between tPAHs concentration in August and February (P>0.05). Based on the number of aromatic rings in the molecular structure, the composition pattern of PAHs was different within studied stations. The studied stations receives their PAHs from both petrogenic and pyrolitic sources. The level of PAHs contamination in the Bushehr coastline founded to be moderate to high compared with other studied locations. Regular monitoring of PAHs contaminant in the region is recommended.

Abstract: In a survey of the Population of Behbahan city, carried out in years 1990-91, the mean age was approximated up to 15.2 and 17.5 in the villages and the city, respectively. Furthermore, about 27.4% and 27.9% of the corresponding populations were under 5 years of age. The birth rate in the urban and rural areas was about 31.2 and 33.3 per thousand live births. Mortality rate related to the immaturity and low-birth weight were two times more in villages than in the city. There is a meaningful relationship between intent’s body weight and IMR in the villages but both in the city.
Neurological Manifestations, Diagnosis, and Treatment of Celiac Disease: A Comprehensive Review
Shahriar Nikpour
Iranian Journal of Neurology , 2012,
Abstract: Celiac disease or gluten sensitivity may initially present asone or more neurological signs and/or symptoms. On the other hand, it may be associated with or complicated by neurological manifestations. Neurological presentations are rare in children but as many as 36% of adult patients present with neurological changes. With severe malnutrition after progression of celiac disease, different vitamin deficiencies may develop. Such problems can in turn overlap with previous neurological abnormalities including ataxia,epilepsy, neuropathy, dementia, and cognitive disorders. Inthis study, we aimed to review the neurological aspects of celiac disease. Early diagnosis and treatment could prevent related disability in patients with celiac disease.
Detection Tool for Unbalanced Bids  [PDF]
Babak Nikpour, Ahmed Senouci, Neil Eldin
Open Journal of Civil Engineering (OJCE) , 2017, DOI: 10.4236/ojce.2017.73028
Abstract: Unbalanced bidding is a cash flow management strategy that is recognized as an illegal/disqualifying practice by public owners; and unethical practice by most private owners. This practice provides the awarded bidder with unjustified advantages at the expense of the owner. Unfortunately, limited tools and techniques are currently available to identify and detect unbalanced bids during the evaluation process. This paper presents an innovative detection tool to identify unbalanced bids in unit price contracts during the bid evaluation process. The proposed technique develops BMDI graphs to visualize total markup variation patterns during the project lifetime to detect unbalanced bids. The proposed method also uses Monte Carlo simulation to take in consideration the impact of cost uncertainties and risks. An illustrative example was presented to show the capabilities and features of the proposed method in determining the status of submitted bids during the evaluation process.
Translational Researches Require Effective Protocols for Knowledge and Technology Transfer and Integration

Abstract: Integration of several disciplines (nonclinical, preclinical and clinical researches) during drug discovery and development through learn and confirm process need a dynamic process “translational medicine” (TM) to give a holistic understanding of the entire process. To achieve the highest impacts, however, effective standard protocols need to be performed.
Integration of Molecular, Cellular and Translational Researches in BioImpacts
Yadollah Omidi
BioImpacts , 2011,
Abstract: Integration of molecular cellular biology with advanced technologies (e.g., bioinformatics, omics, biophotonics and nanobiosensing) has significantly improved the translational medicine field. The integrative research in various biomedical sciences has also fastened the progression of drug discovery and development. Aiming to meet the highest standards of publication, the newly established multidisciplinary open access journal “BioImpacts” grants a free platform for all authors and readers to facilitate the integration of different scientific domains in biomedical sciences.
Smart Multifunctional Theranostics: Simultaneous Diagnosis and Therapy of Cancer
Yadollah Omidi
BioImpacts , 2011,
Abstract: Clinical applications of advanced nanomedicines such as PEGylated liposomal doxorubicin and paclitaxel-albumin bioconjugates have significantly improved the cancer treatment strategies. However, these pharmaceuticals lack early detection and single cell tracking capabilities. Thus, engineering of smart multifunctional theranostics appear to be our next stepfor simultaneous diagnosis and therapy of cancer. Clinical translation of multifunctional theranostics appears to be dependent upon specificity of cancer biomarkers, biocompatibility of components used for formulation, and advancement of bioconjugation techniques. While many cancer biomarker candidates often fail to be used for clinical diagnosis/therapy because of their nonspecific functional expression in normal tissues, biocompatibility of materials used for bioconjugationalso needs to be approved. All these issues need to be fully addressed prior to the translation of smart multifunctional cancer theranostics.
CNT Nanobombs for Specific Eradication of Cancer Cells: A New Concept in Cancer Theranosticss
Yadollah Omidi
BioImpacts , 2011,
Abstract: Whole extermination of cancerous cells/tissue seems no longer to be a dream. Exploiting advanced photoactive nanomaterials such as functionalized fullerenes and carbon nanotubes (CNTs) can act as CNT nanobombs (CNT-NBs) when exposed to the near infrared (NIR) radiation. PEGylated CNTs tagged with an antibody/aptamer can target cancer cells. Once attached to cancer cells, the NIR emission (700-1100 nm), in which body tissues are mostly transparent, can be applied to CNT-NBs which can absorb the light and get heated up. The resultant enhanced temperature can abolish the cancer. Once stealth CNT-NBs are tagged with imaging moieties, it would be a matter of computer gaming for physician who can inject it for real time visualization and destruction of cancer by activation of the NIR laser. While, many nanosystems (NSs) are still in waiting list for clinical translation, our dreams may come true by applying stealth CNT-NBs against cancer.

Journal of Research in Health Sciences , 2011,
Abstract: Background: Quality management is one of the most effective strategies for improving Health system performance in developed and developing countries. This research was a comparative study on quality management models in health system of several countries. The main goal of this study was to identify the most significant dimensions of quality management and propose appropriate model for health system. Methods: In this research Asian, African, European, North and South American countries that have backgrounds in implementation of total quality models in health sector, were elected via a convenient sampling. In addition this study included World Health Organization and World Bank experiences concerning quality in several countries. Results: showed that in 22 studies in developing countries, outcome criteria do not exist, 7 studies utilized structural indicators and 3 studies utilized both process and structural indicators for assessing the quality of healthcare, Also main goals of quality improvement in these countries were: increasing service efficiency, improving quality of services, improving quality of work life, cost decreasing, waste eliminations, appropriate usage of resource and developing organizational culture. Conclusions: General approaches to quality in these countries were: Quality Assurance, ISO 9002, cultural development, Total Quality Management, process documentations and quality improvement projects. The most significant problems in implementation of qua
