M.J Nasiri Kashani
Qom University of Medical Sciences Journal , 2012,
Abstract: Background and Objectives: Shallots are an important part of the diet of many populations and show some different pharmacological effects in different medical aspects. Some studies have been performed to evaluate the antimicrobial effects of shallots. The objective of this survey was to evaluate its antifungal activities in several fungal species. Methods: In this experimental study, after extracting shallot by soxhlet's procedure, antifungal effects of alcoholic and aqueous extracts of shallot (Allium hirtifolium) against 5 saprophyte species (Aspergillus fumigatus, Aspergillus flavus, Aspergillus niger, Penicillium gryseogenum and Alternaria) and 2 dermatophyte species (Microsporum canis and Trichophyton mentagrophytes) were evaluated in vitro. Minimum Inhibitory Concentrations (MICs) were determined by broth macrodilution method and finally were compared with miconazole. Results: Allium hirtifolium showed antifungal effects against all the tested fungi with MIC ranged between 0.058 to 0.8 mg/ml for alcoholic extract and 0.26 to 3.84 mg/ml for aqueous extract, respectively. Minimum Fungicidal Concentrations (MFCs) of alcoholic and aqueous extracts ranged between 0.1 to 12.8 mg/ml and 0.6 to 68.26 mg/ml, respectively. Conclusion: This study indicated that shallot crude juice has antifungal activity and looks promising to be an alternatative for chemical antifungal agents that have sometimes serious side effects.

African Journal of Biotechnology , 2009,
Abstract: To assess the genetic relations inPisum genus and to examine putative duplicate accessions, 20 pea varieties (Pisum sativum L.) with 57 accessions from wild Pisum species fulvum, subspecies (subsp.) asiaticum, elatius, thebaicum, abyssinicum, transcaucasicum and arvense were analyzed using 10 out of 20 microsatellite primer pairs. We genotyped all accessions. In total, 59 alleles were identified in whole collection. The maximum number of alleles (8 alleles) was obtained from the PEACPLHPP, AF004843, and AA43090 loci. The maximum number of private alleles (4) in the wild collection was detected in AF004843 locus but in the cultivar collection, it was detected in AA430902 and PSBLOX13.2 loci. Cluster analysis and principal coordinate analysis located accessions in 3 groups and cultivated varieties were obviously separated from the wild accessions. Analysis of molecular variance (AMOVA) revealed that the intergroups component of variance (29%) is lower than the intragroups component of variance (71%).

Splenic vein thrombosis with chronic pancreatitis: a case report and literature review
Nasiri SH, Khorgami J, Donboli K
Tehran University Medical Journal , 2008,
Abstract: "nBackground: Chronic pancreatitis and perivasculitis is the most common etiology of splenic vein thrombosis (SVT). Reported in up to 45% of patients with chronic pancreatitis, SVT may also be seen in patients with acute pancreatitis and pancreatic adenocarcinoma. It causes a localized portal hypertension called sinistral portal hypertension. Unlike those with generalized portal hypertension, patients with sinistral portal hypertension are asymptomatic and have normal liver function. Upper gastrointestinal bleeding from gastric varices is a life threatening complication of SVT. In patients with gastrointestinal bleeding secondary to esophageal or gastric varices, late-phase celiac angiography is used to determine the presence SVT. Splenectomy is effective in treating the collateral outflow for patients with massive gastrointestinal bleeding."n"nCase report: a 23-year-old patient with SVT due to chronic pancreatitis with gastrointestinal bleeding. The patient came to the hospital with upper gastrointestinal bleeding of unknown etiology. Diagnostic workups revealed chronic pancreatitis and SVT with bleeding gastric fundal varices, after which the patient underwent splenectomy. A review of current literature on SVT, known etiologies, diagnosis and treatment is discussed
DEXAMETHASON ADMINISTRATION IN INTRAVENOUS REGIONAL ANESTHESIA: ITS AFFECT ON POST OPERATIVE PAIN A RANDOMIZED DOUBLE BLINDED CLINICAL TRIAL

Journal of Research in Medical Sciences , 2002,
Abstract: Introduction. Intravenous regional anesthesia (IVRA) is one of the successful method of anesthesia in relief of pain of surgery. It has a multiple advantages including feasibility, rapidity of recovery, rapid onest, muscular relaxation and controllable onset of anesthesia. But this technique dose not relief postoperative pain. In the previous studies it had been tried to add some drugs to local anesthetic in IVRA for relief postoperative pain. Methods. One hundred and ten adult patients in class I and II ASA scheduled for elective operation of unilatral upper extrimeties under IVRA, randomly allocated into interventional and control groups. NRA was done with Lidocaine 0.5 percent with or without dexamethason. Postoperative pain was assessed by visual analogue scale. Results. Addition of dexamethason to local anesthetic in IVRA resulted in better tolleration of turniquate pain and reduced VAS score. Frequency of severe postoperative pain was reduced in case group. Discussion. It seems that dexamethason usage in local anesthetic in IVRA prevents sever postoperative pain in patients. The results of this study is simillar to the study wich added ketorolac to IVRA solution.

Quantum Potential and Symmetries in Extended Phase Space
Sadollah Nasiri
Symmetry, Integrability and Geometry : Methods and Applications , 2006,
Abstract: The behavior of the quantum potential is studied for a particle in a linear and a harmonic potential by means of an extended phase space technique. This is done by obtaining an expression for the quantum potential in momentum space representation followed by the generalization of this concept to extended phase space. It is shown that there exists an extended canonical transformation that removes the expression for the quantum potential in the dynamical equation. The situation, mathematically, is similar to disappearance of the centrifugal potential in going from the spherical to the Cartesian coordinates that changes the physical potential to an effective one. The representation where the quantum potential disappears and the modified Hamilton-Jacobi equation reduces to the familiar classical form, is one in which the dynamical equation turns out to be the Wigner equation.
Fetal Electrocardiogram Signal Extraction by ANFIS Trained with PSO Method

International Journal of Electrical and Computer Engineering , 2012, DOI: 10.11591/ijece.v2i2.231
Abstract: Studies indicate that the primary source of distress in pregnent mothers is their concerns about fetus’s condition and health. One way to know about condition of fetus is non-invasive fetal electrocardiogram signal extraction through which the components of fetal electrocardiogram signal are extracted from a signal recorded at abdominal area of mother which is a combination of fetal and maternal electrocardiogram signal and noise source components. The purpose of this study is to propose an algorithm to boost this extraction. To this end, we decomposed electrocardiogram signal to its Intrinsic Mode Functions (IMFs) thruogh Empirical Mode Decomposition algorithm; then, we removed the last and collected the other IMFs to reconstruct electrocardiogram signal without Baseline. Afterwards, we used Particle Swarm Optimization to train and adjust the parameters of Adaptive Neuro-Fuzzy Inference System to model the path that maternal electrocardiogram signal travel to reach abdominal area. Accordingly, we were able to distinguish and remove maternal electrocardiogram signal components from the recorded signal and hence we obtained a good approximation of fetal electrocardiogram signal. We implemented our algorithm and other algorithms on simulated and real signals and found out that, in most cases, the proposed algorithm improved the extraction of fetal electrocardiogram signal.
