Abstract: During 2007 and 2008, soil samples of wheat and barley fields of the cold regions of the Kohgiluyeh and Boyer-Ahmad province were surveyed for cereal cyst nematode. In 65% of samples cysts were seen. Morphological and morphometrics of cysts, cone top structure and second stage juveniles of the isolated populations were studied. Detailed taxonomic studies revealed the existence of H. filipjevi. This is the first report of the species in the province.
On an M/G/1 Queueing Model with k-Phase Optional Services and Bernoulli Feedback  [PDF]
Sayeedeh Abdollahi, Mohammad Reza Salehi Rad
Journal of Service Science and Management (JSSM) , 2012, DOI: 10.4236/jssm.2012.53033
Abstract: In this article an M/G/1 queueing model with single server, Poisson input, k-phases of heterogeneous services and Bernoulli feedback design has been considered. For this model, we derive the steady-state probability generating function (PGF) of queue size at the random epoch and at the service completion epoch. Then, we derive the Laplace-Stieltjes Transform (LST) of the distribution of response time, the means of response time, number of customers in the system and busy period.
The major role of toxicology societies in global collaborations – a call to action
Jeffrey Brent, Mohammad Abdollahi
DARU Journal of Pharmaceutical Sciences , 2012, DOI: 10.1186/2008-2231-20-11
Abstract: While the concept of the internationalization of toxicology can take the form of collaborative relationships between individual scholars and researchers with overlapping interests, the true potential of such collaborations can best be realized when larger institutions such as governments or professional societies join forces. A classic example of such a collaboration is when the American Academy of Clinical Toxicology (AACT) and the European Association of Poison Control Centres and Clinical Toxicologists (EAPCCT) jointly generated a series of scholarly position statements that resulted in a major upheaval in the approaches to gastrointestinal decontamination in poisoned patients—an upheaval that is still being felt in clinical practice today and one that has enhanced the care of our patients. This collaboration between societies, an important event in the history of clinical toxicology, should serve not just as position statements, but more importantly as an emblematic model of the way professional toxicological societies can interact.The patterns of international scientific collaboration can be investigated by analyzing scientometric databases for internationally co-authored articles. Such an investigation shows that the science of toxicology is growing globally. For example, when countries from different regions of the world are searched in SCImago for their scientific production in toxicology, then the top countries from 10 regions of the world are as follow: Iran from Middle East, UK from Western Europe, Poland from Eastern Europe, Tunisia from Northern Africa, Nigeria from Central Africa, South Africa from Southern Africa, USA from Northern America, Brazil from Latin America, China from Asiatic Region, and Australia from Pacific region.If the number of registered toxicologists from societies of these countries from the IUTOX database are counted, an estimated 4000 members are found. The actual number of toxicologists is undoubtedly much higher since many socie
Current Opinion on Nanotoxicology
Ali Pourmand, Mohammad Abdollahi
DARU Journal of Pharmaceutical Sciences , 2012, DOI: 10.1186/2008-2231-20-95
Abstract: As requiring toxicologists to become nanotechnology experts would not be feasible, to properly incorporate the care of nanotoxicity into the existing medical framework, a range of experts across multiple fields of study must work in close synchronization. The focus needs to be on mechanism-driven research to ensure a solid scientific foundation for the assessment of NP and their role in healthcare.Nanotechnology is one of the premiere technologies available today, having expanded both as field of scientific study and in the public consciousness. Despite this growth, the drawbacks, limitations and potential safety hazards associated with the incorporation of nanotechnology into existing industries are still being learned. The noticeable point is that there is no enough data available yet to analyze global use of nanotechnology from a meta-perspective.The conventional definition of a nanoparticle (NP) is a material or materials with two or three dimensions, between 1 and 100 nm and possessing strange properties related to the size, shape or chemical composition of the material. The term nanotechnology can be defined as “the manipulation, measurement, precision, modeling, or manufacture of sub-100 nanometer scale matter” [1]. Today, over 800 consumer products are estimated to incorporate nanoparticles [2,3].Of particular interest to the medical field is the potential advantage of nanotechnology in both diagnostic and therapeutic approaches. The ability to operate at the cellular or intercellular level could lead to dramatic leaps in the patient care. As of this writing, NPs are being developed to meet a variety of needs, however very few NPs have made it out of the testing phase. Over the last five years, production of NPs has increased five-fold. The current approximation is that more than 580 companies over 30 countries manage and produce some 1,317 NP-based projects, from textiles to wound dressings [2]. Some scientists have speculated that nanotechnology is growing
Herbal medicines for the management of irritable bowel syndrome: A comprehensive review
Roja Rahimi,Mohammad Abdollahi
World Journal of Gastroenterology , 2012, DOI: 10.3748/wjg.v18.i7.589
Abstract: Irritable bowel syndrome (IBS) is a functional gut disorder with high prevalence. Because of various factors involved in its pathophysiology and disappointing results from conventional IBS medications, the treatment of IBS is challenging and use of complementary and alternative medicines especially herbal therapies is increasing. In this paper, electronic databases including PubMed, Scopus, and Cochrane library were searched to obtain any in vitro, in vivo or human studies evaluating single or compound herbal preparations in the management of IBS. One in vitro, 3 in vivo and 23 human studies were included and systematically reviewed. The majority of studies are about essential oil of Menta piperita as a single preparation and STW 5 as a compound preparation. Some evaluated herbs such as Curcuma xanthorriza and Fumaria officinalis did not demonstrate any benefits in IBS. However, it seems there are many other herbal preparations such as those proposed in traditional medicine of different countries that could be studied and investigated for their efficacy in management of IBS.
Systematic review of modulators of benzodiazepine receptors in irritable bowel syndrome: Is there hope?
Pooneh Salari,Mohammad Abdollahi
World Journal of Gastroenterology , 2011, DOI: 10.3748/wjg.v17.i38.4251
Abstract: Several drugs are used in the treatment of irritable bowel syndrome (IBS) but all have side effects and variable efficacy. Considering the role of the gut-brain axis, immune, neural, and endocrine pathways in the pathogenesis of IBS and possible beneficial effects of benzodiazepines (BZD) in this axis, the present systematic review focuses on the efficacy of BZD receptor modulators in human IBS. For the years 1966 to February 2011, all literature was searched for any articles on the use of BZD receptor modulators and IBS. After thorough evaluation and omission of duplicate data, 10 out of 69 articles were included. BZD receptor modulators can be helpful, especially in the diarrhea-dominant form of IBS, by affecting the inflammatory, neural, and psychologic pathways, however, controversies still exist. Recently, a new BZD receptor modulator, dextofisopam was synthesized and studied in human subjects, but the studies are limited to phase IIb clinical trials. None of the existing trials considered the neuroimmunomodulatory effect of BZDs in IBS, but bearing in mind the concentration-dependent effect of BZDs on cytokines and cell proliferation, future studies using pharmacodynamic and pharmacokinetic approaches are highly recommended.

An Update on Pharmacology of Satureja Species; From Antioxidant, Antimicrobial, Antidiabetes and Anti-hyperlipidemic to Reproductive Stimulation
Saeideh Momtaz,Mohammad Abdollahi
International Journal of Pharmacology , 2010,
Abstract: Since ancient, the genus Satureja L. is well recognized for its therapeutic values. Only recently, scientists have been aware of its new medicinal aspects. In our last review, we evaluated existing scientific data about this genus. Regarding ongoing reports and new multi-functional properties of this plant we were interested to update pharmacology of Satureja. Data were gathered using of scientific books, journals, articles and websites including Pubmed, Scopus and Google Scholar up to 25th April 2010. Of initial search, 1540 records were reviewed for inclusion or exclusion in study, of which 71 publications were included. Different species of Satureja are famous for their analgesic, antiseptic, antimicrobial, antiviral, antioxidant, antiproliferative, antiprotozoal, antifungal, antidiarrheal, anti-inflammatory, anti-nociceptive, anticholinesterase and vasodilatory activities. The valuable therapeutic aspects of this genus are mostly correlated to the existence of essential oils, flavonoids and triterpenoids. The combination of two or more subspecies acting by different mechanisms to produce a synergistic effect should be considered. Based on the conducted assessments so far, antibacterial, antifungal, antiviral, antioxidant, anti-diabetic, vasodilatory and analgesic activities are characterized as the most applicable properties of Satureja subspecies. Further studies are needed to confirm novel pharmacological aspects of this genus in both animal and human.
