T-Helper Cytokine Patterns and Related Antibodies in Patients with Gestational Diabetes Mellitus
Z Etaati,R Moazzami Godarzi,F Kalhori,SA Sobhani
Tehran University Medical Journal , 2012,
Abstract: Background: Diabetes mellitus (DM) is a group of metabolic disorders such as DM I, DM II, secondary causes of DM and gestational diabetes mellitus characterized by hyperglycemic phonotype. The etiology of gestational diabetes mellitus is unknown. Recent studies address the chronic activity of immune system against infections (not autoimmunity) as an important cause of gestational diabetes mellitus. This study aimed to compare T-helper cells 1 and 2 cytokines and associated antibodies in patients with gestational diabetes mellitus and normal pregnant women. Methods: This cross-sectional study was performed on 45 female patients with GDM and 45 healthy pregnant women in Bandar Abbas, Iran, from 2008- 2009. The exclusion criteria were presence of any infectious diseases or autoimmune disorders such as SLE or RA. Present and past medical histories were taken from the participants thorough physical examination. Blood samples (10 mL) were drawn and sent to laboratory for measuring serum IgE, IgG1, IgG2, IgG3, IgG4, interleukin-10 (IL-10), interleukin-12 (IL-12), transforming growth factor-beta (TGF 1), and interferon-gamma (IFN ) measurements. T-test and Kolmogorov-Smirnov test were used for data analysis. Results: The mean age of the patients with GDM and healthy pregnant women was 32.5 and 27.9 yrs, respectively. T-helper 1 and 2 associated antibodies and cytokines had no significant differences between the case and control groups. Conclusion: The changes in T-helper 1 and 2 associated antibodies and cytokines are not associated with gestational diabetes mellitus and could not be considered as a predictor for gestational diabetes mellitus.
The Violation of Cooperative Principles and Four Maxims in Iranian Psychological Consultation  [PDF]
Arezou Sobhani, Ali Saghebi
Open Journal of Modern Linguistics (OJML) , 2014, DOI: 10.4236/ojml.2014.41009
Abstract:

This paper aimed to investigate new ways of understanding non-cooperative attitudes of the speakers and the violation of Cooperative Principle maxims in real Iranian psychological consulting session. The data base consists of recorded conversations between a male psychotherapist and his patients during therapy sessions. After analysing their language by means of conversational implicature and the occurrences of the violation of Cooperative Principle, it is concluded that the recognition of conversational implicature is essential for the understanding of the non-cooperative attitudes of the speakers and their violation of one or more Cooperative Principle maxims. Moreover, it was clear that the message people intend to convey is not wholly contained within the words they use, but it is also dependent on how hearers interpreting the message taking into account context and implicated meaning. Finally, there were instances when the purpose was to intentionally miscommunicate within this sophisticated social context. The study has a contribution to the existing knowledge in the area of pragmatics and psychology development.

Gray isometries for finite $p$-groups
Reza Sobhani
Transactions on Combinatorics , 2013,
Abstract: We construct two classes of Gray maps, called type-I Gray map and type-II Gray map, for a finite $p$-group $G$. Type-I Gray maps are constructed based on the existence of a Gray map for a maximal subgroup $H$ of $G$. When $G$ is a semidirect product of two finite $p$-groups $H$ and $K$, both $H$ and $K$ admit Gray maps and the corresponding homomorphism $psi:Hlongrightarrow {rm Aut}(K)$ is compatible with the Gray map of $K$ in a sense which we will explain, we construct type-II Gray maps for $G$. Finally, we consider group codes over the dihedral group $D_8$ of order 8 given by the set of their generators, and derive a representation and an encoding procedure for such codes.
Anthropometric Evaluation of Nutritional Status in Primary School Students at Bandar Abbas (2001 – 2002)
T Aghamolaei,A Sobhani
Journal of School of Public Health and Institute of Public Health Research , 2004,
Abstract: Primary school students constitute an important demographic category: the fact that they are going through a phase of rapid physical, social and mental growth makes them especially vulnerable to the obnoxious effects of disease and malnutrition. In Iran, one of the major causes of malnutrition and growth deficiency is lack of food. The objective of this study was using anthropometric techniques to assess nutritional status in primary school students at Bandar Abbas. This is a cross-sectional study involving 1300 subjects selected by cluster sampling. Indices used in this study were weight for age (W/A), weight for height (W/H), and height for age (H/A). Malnutrition was defined as an index value more than 2 standard deviations below the standard level. We found wasting (W/H) in 15.7%, stunting (H/A) in 11.7% and underweight (W/A) 21.2% of the subjects, with no significant difference in nutritional status between boys and girls. Prevalence of all three types of malnutrition increased with age and school grade. Students who had received nutrition education showed better nutrition status compared to those without such background education. Measures to control malnutrition can include education, proper recording and follow-up of nutrition and growth data in the form of health files, and nutritional interventions. The latter is particularly relevant in higher age groups and school grades.

Epigenetic Effect of Chronic Stress on Dopamine Signaling and Depression
Sofia Moriam and Mahbub E. Sobhani
Genetics & Epigenetics , 2012, DOI: 10.4137/GEG.S11016
Abstract: Because of the complex causal factors leading to depression, epigenetics is of considerable interest for the understanding effect of stress in depression. Dopamine is a key neurotransmitter important in many physiological functions, including motor control, mood, and the reward pathway. These factors lead many drugs to target Dopamine receptors in treating depressive disorders. In this review, we try to portray how chronic stress as an epigenetic factor changes the gene regulation pattern by interrupting Dopamine signaling mechanism.
Optimization of an existing forest road network using Network 2000
Mohammad Reza Ghaffarian,Hooshang Sobhani
Croatian Journal of Forest Engineering , 2007,
Abstract: Optimization of forest road network is an important part of logging planning. Matthews (1942) was the first to introduce a method for optimization of road spacing based on minimization of roading and skidding cost. The goal of this paper is to find the best road network for a district harvested by skidder. The skidding model developed by stepwise regression model was used to predict the cost of skidding per cubic meter for the 39 nodes, which were planned in the district map. The harvesting volume and roading cost per each node were computed.The data were entered into NETWORK 2000 and shortest path algorithm; simulated annealing and great deluge algorithms were run to find the best solution to optimize logging cost of the district. The results showed which roads can be eliminated from the existing forest road network.

Journal of Dental Medicine , 1999,
Abstract: One of the major goals of periradicular surgery is to create a good apical sea! at the apex. This"nis done by sectioning of 2 to 3mm from the apex, preparation of a class I cavity and filling with a"nbiocompatible material."nThe purpose of this in vitro study was to determine whether ultrasonic units used for root end"npreparations could change the surface & structure of resected root ends, as competed to common"nmethods of retropreparation. Eighty-five extracted single rooted teeth were divided into five similar"ngroups. Then instrumented and filled with lateral condensation method. Then three millimeter of apex"nwas resected, retropreparaiions in two groups were done with low speed handpiece and round V) ^ur"nand cavities in two other groups prepared with the highest power of dentspiay ultrasonic unit with TFI-"n10 tip and in one other group prepared with the highest power of neo sonic ultrasonic unit with diamond"ncoated CT-1 retro tip."nFollowing root resection and retropreparation the surface of resected root ends were examined for the"npresence of any cracks or structural changes on the surface of resected root ends with stereo microscope"n50x."nThe results of this study showed thai high power settings of ultrasonic units can increase the potential of"ncrack formation on resected root surfaces. In conclusion it is better to use low power setting of ultrasonic"nfor retropreparation.
Acquired Hemophagocytic Lymphohistiocytosis: A Case Report
M Hashemieh,A Sobhani Araghi
Iranian Journal of Pediatrics , 2006,
Abstract: Background: Hemophagocytic lymphohistiocytosis (HLH) is a rare and potentially fatal disease of normal but overactive histiocytes (macrophages) that commonly appears in childhood. A fever, hepatosplenomegaly, pancytopenia, lymphadenopathy, and a rash often comprise the initial presentation. Cutaneous involvement occurs in up to 65% of patients. Although the signs of central nervous system (CNS) involvement may be pronounced early, it usually develops later during the course of the disease. The pathological hallmark of this disease is the aggressive proliferation of activated macrophages and histiocytes, which phagocytose other cells, namely red blood cells, white blood cells, and platelets, leading to the clinical symptoms. Case Report: This paper presents a 4- years old girl that was admitted to the hospital because of abdominal distention .Her vital signs were normal. Physical examinations by her physician were revealed hepatosplenomegaly. She had pancytopenia, high erythrocyte sedimentation rate but tests for liver and kidney-functions were normal in primary laboratory data. The results of tests for viral hepatitis A, B, and C were negative. An abdominal ultrasonographic study confirmed the presence of hepatosplenomegaly, but no ascites was detected. Examination of a stained bone marrow aspirate (BMA) revealed dyserythropoietic change. After 2 months, she presented with intermittent fever but three blood cultures yielded no growth at 48 hours. A liver biopsy was done and it showed a picture similar to chronic persistent hepatitis. Again, she has undergone bone marrow aspiration and showed the same findings with the past BMA (dyserythropoietic change) .She was candidate for bone marrow biopsy and explorative laparotomy. During explorative laparotomy, specimens from liver (again), spleen, pancreas, and abdominal lymph nodes was obtained. There was evidence of hemophagocytosis in the spleen, marrow, lymph nodes specimens and the results of complementary laboratories were consistent with a "Hemophagocytic Lymphohistiocytosis".
