Relationship between loss of exercise consequences and risk of cardiovascular diseases after detraining
Mehdi Mogharnasi,Mahtab Nasseh
Zahedan Journal of Research in Medical Sciences , 2011,
Abstract: Background: The studies show that regular exercise may play an important role in improvement the cardiovascular status and with detraining period people will loose its useful outcome. The aim of this study was to assess the effect of short detraining period on cardiovascular biomarkers in Wistar rats.Materials and Method: Forty-two male rats were divided randomly in two groups: experimental group (n=24) and control group (n=18). The training program was done 3 times per week, for 8 weeks. Then six rats experienced detraining. The blood samples were collected after 14 fasting hours in different stages and with the same conditions. The quantity of sICAM-1 was measured, using the commercial R&D Elisa kit. The quantity of total cholesterol (TC), triglyceride (TG), HDL & LDL in plasma was measured by using Pars-Azmoon kits. Data were analyzed by Kolmogrov-Smirnov, repeated measures of ANOVA, LSD and t-test. The amount of errors were computed in the level of p<0.05.Results: Thirty-six sessions of aerobic training made significant changes in variables and after 4 weeks of detraining the amount of measured variables were changed in to the insignificant baseline level. There were significant changes when detraining group compared with training group at the end of study [sICAM-1 (p=0.006), TC (p=0.004), TG (p=0.005) & LDL-C (p=0.037), HDL-C (p=0.037)].Conclusion: The results showed, detraining casuses the increase of dangerous factors and body faces the risk of cardiovascular diseases and atherosclerosis

A. Jafari,Y. Nasseh
Asian Journal of Plant Sciences , 2009,
Abstract: In present research anatomical studies carried out 11 species which growing in Khorassan Province (North-East of Iran). These species were divided to two groups, annual and perennial species. For comparative anatomy studying, cross sections from stem and leaf were prepared using microtome and differential staining. The characters of secondary xylem and axial parenchyma, arrangement of vessel and the arrangement of mesophyll were studied. The results showed the variation of internal structure didn`t have correspondence to taxonomy position.
On Ext-indices of ring extensions
Saeed Nasseh,Yuji Yoshino
Mathematics , 2007,
Abstract: In this paper we are concerned with the finiteness property of Ext-indices of several ring extensions. In this direction, we introduce some conjectures and discuss the relationship of them. Also we give affirmative answers to these conjectures in some special cases. Furthermore, we prove that the trivial extension of an Artinian local ring by its residue class field is always of finite Ext-index and we show that the Auslander-Reiten conjecture is true for this type of rings.
A Note on Symmetry in the Vanishing of Ext
Saeed Nasseh,Massoud Tousi
Mathematics , 2009,
Abstract: Avramov and Buchweitz proved that for finitely generated modules $M$ and $N$ over a complete intersection local ring $R$, $\Ext^i_R(M,N)=0$ for all $i\gg 0$ implies $\Ext^i_R(N,M)=0$ for all $i\gg 0$. In this note we give some generalizations of this result. Indeed we prove the above mentioned result when (1) $M$ is finitely generated and $N$ is arbitrary, (2) $M$ is arbitrary and $N$ has finite length and (3) $M$ is complete and $N$ is finitely generated.
Andre-Quillen homology and complete intersection dimensions
Saeed Nasseh,Tirdad Sharif
Mathematics , 2013,
Abstract: We study the relation between the vanishing of Andre-Quillen homology and complete intersection dimensions. As an application, we solve a problem of Avramov and Iyengar related to Quillen's conjecture. We also extend some of the existing results in the literature and give a characterization of algebra retracts of finite Andre-Quillen dimension with respect to complete intersection dimensions.
Golden Research Thoughts , 2012, DOI: 10.9780/22315063
Abstract: Madam Colette was perhaps the most controversial female writer of French literature. During her most productive years as a novelist Colette has written extensively on the themes of childhood, love, marital life. Passionate and tumultuous, her writings were largely based on her own experiences of three successive marriages. Colette attempted to find answers to the troubled life by observing the simplest of things; a spider on its web, one pussy stretching out in the lawn, perfumes of the summer wind, the first rays of the sun which she describes in a subtle and sensual way. The presence of autobiography and fiction in hers novels where 'I' and the 'she' of her successive heroines became the 'me' of Colette, expresses her freedom of existence and to define her own aesthetics. The novelist as such has succeeded in maintaining the critical uncertainty around her work. But this ambiguity may contain valuable information on the genesis, development, and training of her writing. Colette admits to the autobiographical nature of her works and acknowledges presenting fragments of her love life. Conventionally colettienne works are distinguished into two important genres; the novels written in the first person and when the author distances herself from her heroines and also blurs the boundaries between her imaginations and her collections of memories.
Alexandre Dumas: The Original Musketeer
Indian Streams Research Journal , 2012,
Abstract: Alexandre Dumas was the most well loved French historical novelist who created a new genre in classical French literature with his themes of high adventure and romance. Writing in his unique flamboyant style, his stories of intrigues, valour, and of course, love, captured the imagination of the French readership in those days. However, his versatility saw him transcend several genres as a playwright, a columnist, and a wellread travel writer. Today the works of Dumas are immortalised in books of many languages, plays, and cinema.
Software Security Requirements Checklist
Mahtab Alam
International Journal of Software Engineering , 2010,
Abstract: The increasing use of information systems led to dramatically improve the functionalitywith respect to safety, cost and reliability. However, with this growthof information systems the likelihood of vulnerabilities also increases. Securityproblems involving computers and software are frequent, widespread, and serious.The number and variety of attacks from outside organizations, particularlyvia the Internet, and the amount and consequences of insider attacks are increasingrapidly. We routinely hear customers claim that their system is insecure.However, without knowing what assumptions they make, it is hard to justifysuch a claim, and it is important to identify security requirements of the system.Enumerating the security to a system helps system architects develop realisticand meaningful secure software. In this paper, we propose a checklist for securityrequirements and assess the security with the help of a metrics based onchecklist threshold value.
Effect of repeated use on dentin bond strength of two adhesive systems: All-in-one and one-bottle
Shafiei Fershteh,Memarpour Mahtab
Indian Journal of Dental Research , 2009,
Abstract: Aims: To compare the effects of repeated use of two one-bottle adhesives with that of two all- in- one adhesives (with acetone solvent) on bond strength to dentin. Materials and Methods: A flat dentin surface was prepared on 120 bovine incisors using 600- grit abrasive pape. The teeth were randomly assigned into 12 equal groups. The four adhesive systems [Prime and Bond NT (P&B NT), One-Step Plus (OS), iBond (iB), and G-Bond (GB)] were used at baseline, after the lid of the container had been opened 30 times, and after it had been opened 60 times. Before each use of the adhesives, the lids of the containers were left open for 1 min. The resin composites were applied on the dentin in a cylindrical split mold. After thermocycling, shear bond strength test was performed with a universal testing machine at 1 mm/min. We used Kruskal-Wallis and Dunn tests for statistical analysis. Results: There was no statistically significant difference among bond strength (MPa) of the groups of P&B NT (31.9 ± 4.6, 31.8 ± 6.5, 26.1 ± 6.7) and OS (33.2 ± 5.1, 30.9 ± 7, 29.3 ± 5.9), respectively (P > 0.05). The mean of the bond strength of iB and GB after 60 times (15.3 ± 4.1 and 12.2 ± 3.9, respectively) was significantly lower than that of iB and GB at baseline (23.5 ± 4.8 and 22.2 ± 4.5, respectively) (P < 0.05). Conclusions: Repeated use (60 times) of the all-in-one adhesive led to a decline in the dentin bond strength. To avoid this problem it would be advisable to have containers with smaller amounts of adhesive or perhaps those with only a singe dose.
Can Transabdominal Sonography Predict Pelvic Relaxation?
Atoosa Adibi,Mahtab Zargham
Iranian Journal of Radiology , 2009,
Abstract: Introduction: Pelvic relaxation and cystocele is a common problem in middle to old age women. Transabdominal ultrasound (TAS) is a noninvasive, available routine procedure in many situations. We evaluated whether TAS can predict pelvic relaxation or not. "nMaterials and Methods: In a cross sectional case- control study one hundred women 30 years or older were enrolled into the study. An expert female urologist examined the cases for the presence of signs and the grading of pelvic relaxation. A single radiologist blinded to pelvic exam results performed TAS. In the full bladder state the following criteria were recorded: 1. Bladder outlet funneling at rest and valsalva 2. Bladder base position in relation to the superior edge of the pubis symphysis 3. Bladder wall thickness 4. Pelvicaliceal system stasis 5.Post voiding residual urine ( PVR). "nResults: Bladder outlet funneling can predict pelvic relaxation (Se, 91.3%), both at rest and after valsalva. If the bladder base descent is seen below the superior edge of the pubis with the cut off point of 5 mm,it can predict pelvic relaxation. "nConclusion: TAS can be used as a safe and available modality to predict pelvic relaxation
