Cytotoxic Effect of Aqueous Extract of Anastatica hierochuntica L. on AMN-3 Cell Line in vitro

Anastatica hierochuntica L. is distributed throughout Arabain Peninsula, and elsewhere it is locally called "Kuffe Maryam" .All parts of the plant are used in folk medicine. This study amid to investigate the effect of aqueous extract of anastatica hierochunctica L. on the cancer cell lines AMN-3. Anti cancer activity of aqueous extract of  anastatica hierochunctica L. showed anticancer activity against AMN-3  cell line for twelve  concentrations (0.04, 0.09, 0.195, 0.39, 0.78, 1.56, 3.125, 6.25, 12.5, 25, 50, 100) mg/mL  in comparison with negative control. Keywords: Anastatica hierochuntica L., Cytotoxic activity

Identification and characterization of pathogenic viruses in aquatic animal using advanced techniques in order to develop rapid diagnostic kit (shrimp viral disease kit as well as TSV, HPV and MBV )

Shrimp production increasing rapidly in the world and in2013 the production reaches 4.2 MT. In Iran the shrimp production is under development and estimated in 1393, 20 thousand tons produced. In this regards the important subject is health and disease in shrimp farm. The white spot syndrome virus for second time appears in chabahar and damage many farms. Because the aquaculture activity expand in the world in national, regional and international scale, many emerge disease are endanger. In this regard the viral disease is very important and not only decrease the production but also has a side effect in business and national economy. For control and prevention the viral disease, the accurate methods such as PCR kit were developed. In this project the PCR methods with sensitivity, specificity and efficacy was designed and used for detection viral disease. Many viruses have several serotypes and in different area maybe new serotype induce the disease. For this reason, the specific kit will be design. Three viruses consist of MBV, TSV and IHHNV are very pathogenic in shrimp farm and need the specific PCR kit for detection them. In this project the MBV virus was identified and designs a new primer with Oligo software and the primer amplified a part of DNA with 185 bp in the gel. The specificity and sensitivity of primer were checked by IQ2000 Kit and the primer used for detection unknown samples

Themoeconomic optimization of triple pressure heat recovery steam generator operating parameters for combined cycle plants

The aim of this work is to develop a method for optimization of operating parameters of a triple pressure heat recovery steam generator. Two types of optimization: (a) thermodynamic and (b) thermoeconomic were preformed. The purpose of the thermodynamic optimization is to maximize the efficiency of the plant. The selected objective for this purpose is minimization of the exergy destruction in the heat recovery steam generator (HRSG). The purpose of the thermoeconomic optimization is to decrease the production cost of electricity. Here, the total annual cost of HRSG, defined as a sum of annual values of the capital costs and the cost of the exergy destruction, is selected as the objective function. The optimal values of the most influencing variables are obtained by minimizing the objective function while satisfying a group of constraints. The optimization algorithm is developed and tested on a case of CCGT plant with complex configuration. Six operating parameters were subject of optimization: pressures and pinch point temperatures of every three (high, intermediate and low pressure) steam stream in the HRSG. The influence of these variables on the objective function and production cost are investigated in detail. The differences between results of thermodynamic and the thermoeconomic optimization are discussed

The Most Important Herbs Used in the Treatment of Sexually Transmitted Infections in Traditional Medicine

Sexually transmitted diseases (STDs) or venereal diseases are transmitted through various methods of sexual intercourse (oral, vaginal, and anal). The predisposition to contract these types of diseases and infections depends on the immunity system of the body, so the lower the immunity system's strength, the greater the risk of sexually transmitted infections (STIs). The most important pathogenic causes of STIs include bacteria, viruses, and parasites. Phytochemical investigations have shown that medicinal plants are a rich source of antioxidant compounds, biologically active compounds, phenols, etc. They can have an inhibitory effect on germs and infectious viruses and are very important for a variety of parasitic diseases, microbial infections, and STIs. Some of the most important medicinal plants that produce inhibitory effects on the growth and proliferation of pathogenic agents of the STIs were reported in the present article. A number of plants have been reported to be used in the treatment and prevention of genital tract diseases and STIs, and to produce antiviral and antimicrobial effects, including Taxillus, Aristolochia, Syzygium cumini, Albizia adianthifolia, Bidens pilosa, Carica papaya, Ranunculus, Peltophorum africanum, Vachellia karroo, Rhoicissus tridentate, Houttuynia cordata, Panax notoginseng, Nelumbo nucifera, Astragalus, Hypericum aethiopicum, Spondias mombin, Jatropha zeyheri, Ximenia caffra, Trichilia dregeana, Clematis brachiate, Tabernaemontana, Sarcophyton. Phytochemical investigations have examined the therapeutic and clinical effects of medicinal plants, and the use of their active ingredients to produce herbal drugs has been addressed. The results of phytochemical investigations have shown that the most important compounds of these plants include quercetin, isoquercitrin, Dammarane-type saponin, flavonoids, alkaloids, flavonoids, glycosides, terpenoids, steroids, astragalosides, flavonoids and polysaccharides, α-pinene, β-pinene, α-pinene, quercetin, myricetin and luteolin flavonoids, β-pinene, 1,3,8-p-menthatriene, ledene, m-menthane, linalyl acetate and 3-carene. β-sitosterol, lupeol, lupeol, sitosterol, spathulenol, β-sitostenone
