Abstract

Objective: The aim of this study was to estimate genetic diversity and morphological relationships of Phytophthora sojae from Iran. Methods: During 2005ñ2007, 142 isolates of P. sojae were collected from soil samples and diseased soybean plants from Lorestan, Mazandaran, Golestan and Ardabil provinces. Races of the isolates were determined. DNA of fifty isolates of P. sojae was amplified with 20 RAPD and 5 ISSR primers. Results: Five primers amplified 77 fragments, of which 20 were polymorphic, indicating low variability. RAPD and ISSR primers clustered isolates into three distinct groups at 85% similarity. Genetic diversity among isolates detected intra specific variability even among isolates of the same geographic origin. There is no correlation between races, geographical distribution, and molecular markers.

Abstract

Objective: The main objective of this study was to screen and evaluate the potential of fungi that isolated from Orobanche ramosa with potential as biological control agents against the parasitic weed, in laboratory and greenhouse experiments. Methods: In this investigation, isolates of Fusarium solani were recovered from diseased broomrape collected from tomato, eggplant, melon, and watermelon fields in Southern Khorasan. The pathogenicity of isolates was evaluated on O. ramosa stem and seed. Fusarium damaged all of the developmental stages and prevented the damage that broomrape causes to plants. Results: The germination of inoculated seed was significantly reduced, germ tubes of microconidia penetrated all parts of the thick, complex seed testa, and seed contents were destroyed. Pathogenicity tests indicated that F. solani caused lesions of black soft rot and complete deterioration within 5-7 days (100%). They also attacked Orobanche seeds, arresting their germination and causing maceration of non-germinated and germinated seeds after 5-7 days of incubation. This is the first investigation of the effects of F. solani on host plant interactions with broomrape in melon.

Abstract

Objective: It has been shown that deferasirox can reduce blood and tissues lead content in animal models. In this study the effect of deferasirox alone or combined with glycine as an antioxidant was evaluated in chronic cadmium toxicosis in rat. Methods: Male wistar albino rats were exposed to 200 ppm cadmium in the drinking water for 3 weeks and treated thereafter with deferasirox (140 mg/kg), glycine (1000 mg/kg) and deferasirox (140 mg/kg) + glycine (1000 mg/kg) by oral gavages, twice daily for 7 days. The effect of these treatments on blood, liver, kidney, bone and testis cadmium values and parameters indicative of oxidative stress (superoxide dismutase, catalase, glutathione peroxidase and total antioxidant capacity in blood) were investigated. Results: Deferasirox was found to be effective in reducing cadmium level in blood, liver and kidney and glycine reduced cadmium levels in bone. Individual administration of deferasirox or glycine mitigated the effects of cadmium on some indicative parameters of oxidative stress in blood. But the best results were obtained following co-administration of both drugs.

Abstract

Objective: Water scarcity is a growing global problem and increasing population pressures, living standards and the growing demand for environmental quality have evoked all the governments to represent better solutions about water resources management. In addition, there are growing political ties for reducing water use in agriculture that follow enough environmental benefits and increase the welfare of other water consumers. Methods: In addition, there are growing political ties for reducing water use in agriculture that follow enough environmental benefits and increase the welfare of other water consumers. This further increases the economic analysis to check the behavior of farmers using mathematical programming techniques and has been followed the application of Positive Mathematical Programming (PMP) especially. Results: Applied policies include increased 5, 10, 20 and 30 percent in water irrigation prices and reduced 10, 15, 25 and 30 percent in the amount of available irrigation water policies. Farmer's response to these policies showed that increased costs and reduced available irrigation water are effective in accepting deficit irrigation.

Abstract

Objective: Ecosystems with mixed species compared to the ones with pure compositions provide a broader range of options in the fields of biodiversity, conservation, protection and restoration. Nearly all forest plantations are established as monocultures, but research has shown that there are potential advantages to be gained by using carefully designed species mixtures in place of monocultures. This paper reviews recent studies that compare stand development and productivity of mixed and pure plantations. Results: Higher stand-level productivity in mixtures has been found with species interactions. These mixtures can also improve economic return through greater individual-tree growth rates and provision of multiple commercial or subsistence products. More complex plantation mixtures of several species have been used for ecological restoration of degraded lands; these large numbers of species of different successional stages are combined to reduce the need for a series of sequential plantings. Future research needs to examine many more tree species across a wider range of sites.

Abstract

Objective: Intravascular catheter-associated infection has been increasing hospitalization in post-surgery patients mainly due to microbial colonization of the catheter surface and formation of a superficial biofilm layer. The present study is aimed in developing an effective antibacterial device which can prevent colonization of organisms by modification of catheter. Methods: In the present study, the antibacterial activities of intravascular catheters are impregnated with third generation broad spectrum antibiotic cefixime under in vitro conditions. To enhance sustained drug release from the catheter surface, a carrier polyvinyl alcohol was added as a second layer. Biofilm forming abilities for the test cultures were initially determined using a standard Exit-site challenge test viz., Borosilicate tube assay and Microtitre plate assay .These test were performed to evaluate the biofilm production using biofilm index. Results: Qualitative and quantitative antibacterial activity tests were performed in modified catheters. It was observed that modified catheters could potentiality prevent the growth of test organisms. During the in vitro conditions it was observed that the growth and survival all the four high biofilm producers viz., Staphylococcus epidermidis, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and the moderate biofilm producer, Proteus mirabilis were prevented when exposed to drug-carrier coated catheters. These in vitro results suggest that the antibacterial drug-carrier coated catheters can potentially be used to combat catheter colonization and catheterassociated infections.

Abstract

Objective: In this study aimed at evaluating the antifertility effect of the methanolic extract of Abelmoschus esculentus (okro) fruit using albino wistar rat. Methods: Fifty adult male rats weighing 200g to 300g were weighed and divided into five groups of five rats each. Group1 served as the control and were given water and normal rat chaw while groups 2, 3, 4 and 5 served as the test groups and were orally administered with (250, 500, 750 and 1000)mg/kg of okro extract respectively after three weeks of acclimatization. Following six weeks of extract administration, the rats were reweighed and sacrificed. Semen was collected from their caudal epididymis for sperm analysis and their testes were weighed and processed for histological studies. Results: Results from the test groups showed a significant (p≤0.05) reduction in the testicular weight and a significant (p≤0.05) increase in the body weight of the rats when compared with the control group. There was also a significant (p≤0.05) decrease in sperm count and sperm motility with a corresponding increase in the percentage number of abnormal sperm cells The histology of the testes showed degenerating testicular tissues. From the result, we therefore conclude that consistent consumption of okro may be destructive to the testes and as such, could impair male fertility.

Abstract

Objective: In this study investigated effects of different amounts of pelleted manure with urea and micro elements on yield and seed quality of medicinal plants, pumpkin (Cucurbita pepo var. styriaca). Methods: The animal manure and urea as pellet with four levels (150 Kg urea, 50 Kg urea + 3.5 ton animal manure, 100 (Kg) urea+ 1.5 ton animal manure and 150 (Kg) urea+1.5 ton animal manure) located in main plots and microelements with three levels (1000, 2000 and 3000 ppm) including a combination of iron, zinc, manganese and boron were located in subplots. Results showed that the highest number of female flowers, fruit yield, number of seeds per fruit, 1000 seed weight and seed yield was observed in using of 150 (Kg) urea + 1.5 ton manure pellet Increasing of nitrogen levels increased plant growth parameters, yield components and seed yield in pumpkin. Results: There was no significant difference between pelleted manures in seed oil percentage and seed protein but the highest oil yield was obtained in the treatment of 150 (kg) urea + 1.5 ton manure pellet which is related to higher seed yield in this treatment. The highest amounts of mentioned parameters are obtained in concentration of 2000 ppm of microelements except of seed protein which is observed in a concentration of 3000 ppm. At whole among of these fertilizer treatments, 1.5 ton animal manure + 150 (Kg) Urea as pellet with 2000 ppm of microelements is much recommended for maximum qualitative and quantitative properties in pumpkin.

Abstract

Objective: The main objective pursued in this paper is to investigate the energy consumption for drying of potato slices using vacuum-infrared drying method. Methods: Drying of potato slices with the thicknesses of 1, 2 and 3 mm were conducted at vacuum levels of zero (without vacuum), 20, 80 and 140 mm [Hg], infrared radiation at power levels of 100, 150 and 200 W in the three repetition. Results: The results show that with the slice thickness decreases, acts of vacuum and increasing lamp power, energy consumption be reduced. Maximum of energy consumption occurred in a vacuum of 140 mm Hg, but in general it can be stated that by applying vacuum, energy consumption is reduced due to the shortening of the drying time. Data analysis showed that use of vacuum in conjunction with infrared radiation drying increased energy consumption in comparison to merely infrared drying. In the combined vacuum-infrared process, drying time and consequently energy consumption decreased in comparison to the merely infrared drying. The maximum thermal utilization efficiency (31.01%) and minimum energy requirements (5.3 kWh/kg H2O) was calculated for drying of potato slices computed at infrared power of 150 W without vacuum at thickness of 1 mm. The minimum thermal utilization efficiency (2.13%) and maximum energy requirements (185.14 kWh/kg H2O) for drying of potato slices was achieved at infrared radiation power of 100 W with vacuum level of 80 mm [Hg] at thickness of 2 mm.
